Here is a thorough Need for Study section for the topic "Medication Chart Review of Potentially Inappropriate Prescribing in Elderly Inpatients Using Beers Criteria and STOPP/START Criteria":

Need for Study

1. Global Rise in the Elderly Population and Polypharmacy Burden

The world is experiencing an unprecedented demographic transition. Adults aged 65 years and older now constitute the fastest-growing segment of the global population. This age group is disproportionately affected by multiple chronic conditions - hypertension, diabetes mellitus, heart failure, osteoporosis, cognitive decline - which necessitate the concurrent use of multiple medications (polypharmacy, typically defined as 5 or more drugs). A 2022 systematic review and meta-analysis (PMID: 35854209) confirmed that polypharmacy prevalence is rising steadily across healthcare settings worldwide. With each additional drug, the risk of drug-drug interactions, drug-disease interactions, adverse drug reactions (ADRs), and medication errors compounds exponentially.

2. High Prevalence of Potentially Inappropriate Prescribing (PIP) in the Elderly

Potentially Inappropriate Medications (PIMs) are drugs whose risks outweigh their benefits in older adults due to age-related changes in pharmacokinetics (reduced renal and hepatic clearance, altered volume of distribution) and pharmacodynamics (increased receptor sensitivity). Studies using the Beers and STOPP/START criteria consistently report alarming PIM prevalence rates:
  • 12% to 80% of older adults in community, nursing home, and hospital settings receive at least one PIM (PLOS ONE, 2019).
  • In a Spanish nursing home study, 48% of residents had at least one PIM by STOPP criteria vs. 25% by Beers criteria (PMC3780483).
  • In Indian tertiary care settings, STOPP/START identified a significantly higher proportion of PIMs compared to Beers criteria alone (Cureus, 2023).
Despite this documented prevalence, PIP often goes undetected because routine clinical practice lacks a standardized, structured screening process - especially in inpatient settings where prescribing complexity is highest.

3. Serious Clinical Consequences of PIP in Hospitalized Patients

The clinical and economic impact of PIP in elderly inpatients has been extensively documented. A landmark systematic review and meta-analysis of 63 studies (Mekonnen et al., British Journal of Clinical Pharmacology, 2021 - PMID: 34008195) found that PIP in hospitalized older adults is significantly associated with:
  • 91% increased odds of adverse drug event-related hospital admissions
  • 60% increased odds of functional decline
  • 26% increased odds of adverse drug reactions and adverse drug events
  • Increased risk of falls (consistent across all included studies)
A more recent 2026 meta-analysis (Muzzarelli et al., Int J Clin Pharm - PMID: 40996586) further demonstrated that PIMs identified by STOPP/START criteria were associated with a 1.84-fold increased odds of rehospitalization (95% CI 1.08-3.12). These consequences translate into prolonged hospital stays, increased healthcare costs, reduced quality of life, and preventable mortality.

4. Prescribing Omissions: An Equally Critical but Underrecognized Problem

While much attention is paid to overprescribing, prescribing omissions - failure to prescribe clinically indicated medications - are equally harmful and often overlooked. The START (Screening Tool to Alert doctors to Right Treatment) component of STOPP/START specifically addresses this gap. In the Spanish nursing home study, START identified prescribing omissions in 44% of residents - with the most frequent omissions involving cardiovascular and bone health medications. Without tools like START, these omissions would remain invisible to clinicians conducting informal medication reviews.

5. Limitations of Current Prescribing Practices in Inpatient Settings

The inpatient hospital setting is particularly vulnerable to PIP due to:
  • Acute illness altering pharmacokinetics/pharmacodynamics, making previously appropriate drugs suddenly harmful
  • Multiple prescribers across specialties contributing to fragmented prescribing
  • Medication reconciliation failures during admission and discharge transitions
  • Time pressure and cognitive overload on clinicians, with no systematic tool for screening all medications simultaneously
  • Lack of clinical pharmacist integration in many hospitals in low- and middle-income countries
A structured medication chart review using validated criteria at admission and discharge directly addresses these gaps.

6. Superiority and Complementarity of STOPP/START Over Beers Criteria Alone

The Beers Criteria, first published in 1991 and periodically updated by the American Geriatrics Society, is the most widely recognized tool globally. However, it has recognized limitations:
  • Primarily designed for the North American context; many medications listed are not available or rarely used in other countries
  • Does not capture prescribing omissions (no equivalent to START)
  • The STOPP screening tool identified 35% of elderly ED patients with PIMs vs. 25% by Beers, and STOPP-related medications contributed to twice the number of admissions (12% vs. 6%) - as cited in Rosen's Emergency Medicine
STOPP/START version 3 (2023 - PMID: 37256475) has been updated to include a broader physiological systems-based approach, making it more clinically actionable. However, because the two tools detect different subsets of PIP (kappa agreement as low as 0.093 in some studies), using both tools together is recommended for a comprehensive medication review. This complementary use forms the scientific rationale for studies that apply both criteria simultaneously.

7. Gap in Inpatient-Specific, Region-Specific Evidence

While studies on PIP using Beers and STOPP/START criteria exist in community and nursing home settings, there is a relative paucity of inpatient-specific medication chart review studies, particularly from:
  • Developing countries where prescribing patterns, available medications, disease burden, and healthcare infrastructure differ substantially from Western settings
  • Tertiary care hospitals where multi-morbid patients are concentrated
  • Settings with limited clinical pharmacist involvement
A medication chart review in elderly inpatients provides a real-world snapshot of prescribing quality, identifies the most common categories of PIP specific to the local population, and generates data that can inform institutional prescribing policies and clinical pharmacy programs.

8. Potential for Intervention and Improvement

Research consistently shows that medication review using validated criteria, when acted upon, leads to measurable improvement. A 2023 systematic review (PMID: 37582482) found that deprescribing interventions in older patients significantly reduced PIM use and improved clinical outcomes. By identifying the nature and magnitude of PIP at a local level through a chart review study, the groundwork is laid for:
  • Targeted clinical pharmacist-physician collaborative interventions
  • Development of institutional prescribing guidelines for elderly patients
  • Integration of PIM screening tools into electronic health records
  • Training programs for clinicians on geriatric pharmacology

9. Regulatory and Policy Imperatives

Health systems globally are under increasing pressure to improve medication safety in older adults. The WHO's Medication Without Harm global patient safety challenge (3rd Global Patient Safety Challenge) specifically targets reducing medication-related harm by 50% over 5 years, with elderly patients identified as a high-risk group. Inpatient medication chart review studies using standardized tools directly contribute to this global agenda and provide locally applicable, policy-relevant data.

Summary

In short, a medication chart review using both Beers and STOPP/START criteria in elderly inpatients is needed because:

This study is therefore timely, necessary, and directly actionable in improving medication safety for one of the most vulnerable patient populations in any healthcare system.

Give in brief

Need for Study (Brief)

The elderly population is growing rapidly, and older adults commonly suffer from multiple chronic diseases requiring several medications simultaneously (polypharmacy). This increases the risk of Potentially Inappropriate Medications (PIMs) - drugs whose risks outweigh benefits in the elderly due to age-related changes in drug metabolism and sensitivity.
Studies report PIM prevalence of 12-80% in hospitalized elderly patients, yet it frequently goes undetected in routine clinical practice. PIP in inpatients is associated with adverse drug reactions, falls, functional decline, and up to 91% increased odds of ADE-related admissions (Mekonnen et al., 2021). PIMs identified by STOPP/START have also been linked to a 1.84-fold increased risk of rehospitalization (Muzzarelli et al., 2026).
The Beers Criteria and STOPP/START Criteria are the two most widely validated tools for detecting PIP. However, they identify different subsets of inappropriate prescribing (agreement as low as kappa = 0.093), meaning neither tool alone is sufficient. Additionally, the START component uniquely detects prescribing omissions - clinically indicated drugs that were never prescribed - found in up to 44% of elderly patients.
Despite this, inpatient-specific medication chart reviews using both tools simultaneously remain limited, particularly in developing countries where prescribing patterns, disease burden, and available medications differ significantly from Western populations.
This study is therefore needed to:
  • Determine the local prevalence and pattern of PIP in elderly inpatients
  • Compare the detection ability of Beers vs. STOPP/START criteria
  • Identify prescribing omissions through START criteria
  • Generate evidence to guide institutional prescribing policies, clinical pharmacist interventions, and safer prescribing practices for elderly inpatients

Here is a concise Introduction for the study:

Introduction

The global population is ageing at an unprecedented rate. Adults aged 65 years and above now constitute a significant and growing proportion of the world population. This demographic shift has resulted in a parallel increase in the burden of chronic non-communicable diseases such as hypertension, diabetes mellitus, ischemic heart disease, osteoporosis, and cognitive disorders. Managing these conditions often requires the simultaneous prescription of multiple medications, a condition known as polypharmacy (generally defined as the concurrent use of five or more drugs).
Older adults are inherently vulnerable to medication-related harm due to age-related physiological changes in pharmacokinetics and pharmacodynamics - including reduced renal and hepatic clearance, decreased albumin levels altering drug protein binding, reduced total body water increasing drug concentration, and heightened receptor sensitivity. These changes collectively alter the way drugs are absorbed, distributed, metabolized, and eliminated, making elderly patients highly susceptible to adverse drug reactions (ADRs), drug-drug interactions, and drug-disease interactions.
Potentially Inappropriate Medications (PIMs) are defined as drugs whose risks outweigh their clinical benefits in older adults, particularly when safer therapeutic alternatives are available. PIM use is widely prevalent among hospitalized elderly patients, with reported rates ranging from 12% to 80% across various settings globally. PIP in inpatients has been associated with significant clinical consequences including adverse drug events, falls, functional decline, prolonged hospital stay, and increased risk of readmission.
To identify and reduce PIP in clinical practice, several explicit screening tools have been developed and validated over time. The two most widely used are the Beers Criteria and the STOPP/START Criteria.

Beers Criteria

The American Geriatrics Society (AGS) Beers Criteria - originally developed by Dr. Mark Beers in 1991 for nursing home residents - is the oldest and most globally recognized explicit tool for identifying PIMs in older adults. It was designed to be easily applied from pharmacy records with minimal clinical data, making it suitable for quality improvement initiatives. The criteria have since been updated regularly (2003, 2012, 2015, 2019, and most recently 2023 - PMID: 37139824) and are now applicable to all adults aged 65 years and older across ambulatory, acute care, and institutional settings.
The 2023 AGS Beers Criteria is organized into five categories:
  1. Medications to avoid in most older adults regardless of diagnosis
  2. Medications to avoid in older adults with specific diseases or conditions (drug-disease interactions)
  3. Medications to be used with caution in older adults
  4. Potentially harmful drug-drug interactions to avoid
  5. Medications requiring dose adjustment based on renal function
Common drug classes flagged include long-acting benzodiazepines, first-generation antihistamines (e.g., diphenhydramine), tricyclic antidepressants, NSAIDs, antipsychotics, and certain oral hypoglycemics. Each criterion includes a quality-of-evidence rating and strength of recommendation. A key limitation is that the Beers Criteria is primarily designed for the North American context, and does not capture prescribing omissions - i.e., clinically indicated medications that have not been prescribed.

STOPP/START Criteria

The STOPP (Screening Tool of Older Persons' Potentially Inappropriate Prescriptions) and START (Screening Tool to Alert doctors to Right Treatment) criteria were first developed and validated in 2008 by O'Mahony, Gallagher, and colleagues in Ireland, specifically to address the limitations of the Beers Criteria in European clinical practice. They are organized on a physiological systems basis (cardiovascular, CNS, renal, gastrointestinal, etc.), making them more intuitive for clinicians during the medication review process.
  • STOPP criteria identify medications that are potentially inappropriate and should ideally be stopped or replaced.
  • START criteria identify evidence-based medications that are indicated but have not been prescribed - detecting prescribing omissions, which are equally harmful but often overlooked.
Version 2 (2015) expanded the criteria significantly, and the most recent Version 3 (2023 - PMID: 37256475), validated by a pan-European Delphi consensus of 11 academic geriatricians from 8 countries, now contains 133 STOPP criteria and 57 START criteria - a 66.7% increase from version 2. The STOPP criteria have been shown to detect more PIMs than the Beers Criteria (35% vs. 25% in emergency settings), and STOPP-related medications were associated with twice the number of preventable hospital admissions.
Importantly, studies have demonstrated that the two tools identify different subsets of inappropriate prescribing, with agreement as low as kappa = 0.093, confirming that neither tool alone is sufficient for a comprehensive medication review.

Rationale for this Study

Given the high prevalence and serious clinical consequences of PIP in elderly inpatients, the complementary strengths of the Beers and STOPP/START criteria, and the relative paucity of inpatient-specific data in developing countries, a structured medication chart review using both tools simultaneously in hospitalized elderly patients is both timely and clinically relevant. Such a review will help characterize the local pattern of PIP, identify prescribing omissions, compare the performance of the two tools, and lay the groundwork for targeted interventions to improve medication safety in this vulnerable population.

Introduction

The global elderly population (aged ≥65 years) is growing rapidly, and older adults frequently suffer from multiple chronic diseases requiring several medications simultaneously - a condition known as polypharmacy. Age-related changes in pharmacokinetics (reduced renal and hepatic clearance, altered drug distribution) and pharmacodynamics (increased receptor sensitivity) make elderly patients especially vulnerable to adverse drug reactions, drug-drug interactions, and medication-related harm.
Potentially Inappropriate Medications (PIMs) are drugs whose risks outweigh their benefits in older adults, particularly when safer alternatives exist. PIM use is reported in 12-80% of elderly inpatients and is associated with adverse drug events, falls, functional decline, and increased hospital readmissions.
To detect and reduce PIP systematically, two validated explicit screening tools are widely used:
Beers Criteria - Developed by the American Geriatrics Society (first published 1991, latest update 2023), it is an explicit list of medications to avoid or use with caution in adults aged ≥65 years, categorized by drug-drug interactions, drug-disease interactions, and dose adjustments. Though widely used globally, it is primarily designed for the North American context and does not detect prescribing omissions.
STOPP/START Criteria - Developed in Europe (2008, updated versions 2, 3), organized by physiological systems. STOPP (Screening Tool of Older Persons' Potentially Inappropriate Prescriptions) identifies medications that should be stopped, while START (Screening Tool to Alert doctors to Right Treatment) uniquely identifies clinically indicated medications that have been omitted. Version 3 (2023) contains 133 STOPP and 57 START criteria. STOPP detects more PIMs than Beers criteria (35% vs 25%) and captures prescribing omissions that Beers criteria misses entirely.
Since the two tools identify different subsets of PIP (kappa agreement as low as 0.093), using both together provides a more complete picture of prescribing quality. This study aims to conduct a structured medication chart review in elderly inpatients using both criteria to assess the prevalence, pattern, and clinical implications of PIP in a real-world hospital setting.

Introduction (with reference markers)

The global elderly population (aged ≥65 years) is growing rapidly, and older adults frequently suffer from multiple chronic diseases requiring several medications simultaneously - a condition known as polypharmacy [1]. Age-related changes in pharmacokinetics (reduced renal and hepatic clearance, altered drug distribution) and pharmacodynamics (increased receptor sensitivity) make elderly patients especially vulnerable to adverse drug reactions, drug-drug interactions, and medication-related harm [2].
Potentially Inappropriate Medications (PIMs) are drugs whose risks outweigh their benefits in older adults, particularly when safer alternatives exist. PIM use is reported in 12-80% of elderly inpatients and is associated with adverse drug events, falls, functional decline, and increased hospital readmissions [3].
To detect and reduce PIP systematically, two validated explicit screening tools are widely used:
Beers Criteria - Developed by the American Geriatrics Society (first published 1991, latest update 2023) [4], it is an explicit list of medications to avoid or use with caution in adults aged ≥65 years, categorized by drug-drug interactions, drug-disease interactions, and dose adjustments. Though widely used globally, it is primarily designed for the North American context and does not detect prescribing omissions.
STOPP/START Criteria - Developed in Europe (2008, updated versions 2 and 3) [5], organized by physiological systems. STOPP (Screening Tool of Older Persons' Potentially Inappropriate Prescriptions) identifies medications that should be stopped, while START (Screening Tool to Alert doctors to Right Treatment) uniquely identifies clinically indicated medications that have been omitted. Version 3 (2023) contains 133 STOPP and 57 START criteria [5]. STOPP detects more PIMs than Beers criteria (35% vs 25%) and captures prescribing omissions that Beers criteria misses entirely [6].
Since the two tools identify different subsets of PIP (kappa agreement as low as 0.093) [7], using both together provides a more complete picture of prescribing quality. This study aims to conduct a structured medication chart review in elderly inpatients using both criteria to assess the prevalence, pattern, and clinical implications of PIP in a real-world hospital setting.

Review of Literature


1. Polypharmacy and the Elderly - A Growing Concern

The elderly population is disproportionately affected by polypharmacy due to multiple co-morbidities. Delara et al. (2022) [1] in a systematic review and meta-analysis confirmed that polypharmacy is highly prevalent worldwide and is a primary risk factor for adverse drug reactions (ADRs), drug-drug interactions, and potentially inappropriate medication (PIM) use. The risk of ADRs increases exponentially with the number of drugs prescribed, making medication review a priority in elderly inpatient care.

2. Global Prevalence of Potentially Inappropriate Medications

Tian et al. (2023) [2] conducted a systematic review and meta-analysis of 94 studies involving nearly 371 million older adults from 17 countries and reported a pooled global prevalence of PIM use of 36.7% (95% CI 33.4%-40.0%). Asia had a prevalence of 37.2%, while Africa and South America showed the highest rates (47%). Importantly, PIM use was highest in low-income regions and showed an increasing trend over the past two decades, highlighting the need for targeted local studies.

3. PIP in Hospitalized Elderly Patients - Outcomes and Consequences

Mekonnen et al. (2021) [3] in a landmark systematic review and meta-analysis of 63 studies found that PIP in hospitalized older adults was significantly associated with:
  • 91% increased odds of ADE-related hospital admissions
  • 60% increased odds of functional decline
  • 26% increased odds of adverse drug reactions
  • Consistent association with falls
Muzzarelli et al. (2026) [4] further demonstrated that PIMs identified by STOPP/START criteria were associated with a statistically significant 1.84-fold increased risk of rehospitalization (OR 1.84, 95% CI 1.08-3.12), while Beers-identified PIMs showed a non-significant trend (OR 1.25), suggesting STOPP/START may be a more sensitive predictor of adverse outcomes.

4. Inpatient-Specific Studies on PIM Prevalence

Puig et al. (2024) [5], in a multicenter retrospective study of 4,183 elderly inpatients (aged ≥75) across 16 hospitals in Spain, reported a PIM prevalence of 23.5% using Beers, STOPP-START, EU-PIM and PRISCUS criteria combined. Benzodiazepines accounted for 70% of all PIMs. The study noted that 35% of PIMs were initiated before hospital admission and were not withdrawn during the stay, underlining the need for inpatient medication chart review.
In a study on elderly COVID-19 inpatients, Chen et al. (2023) [6] reported that polypharmacy and PIMs were highly prevalent and significantly associated with drug-drug interactions and adverse outcomes, reaffirming the need for systematic PIM screening in all hospitalized elderly patients regardless of the primary diagnosis.

5. STOPP/START vs Beers Criteria - Comparative Performance

Studies comparing the two tools consistently demonstrate that STOPP/START detects more PIMs than Beers criteria in hospital settings:
  • STOPP identified PIMs in 35% of elderly ED patients vs. 25% by Beers criteria, with STOPP-related medications contributing to twice the number of admissions (Rosen's Emergency Medicine) [7].
  • A study in Spanish nursing homes found 48% PIM prevalence by STOPP vs. 25% by Beers criteria [8].
  • A comparison study in Indian elderly patients (Cureus, 2023) [9] reported low inter-tool agreement (kappa = 0.093), confirming that the tools identify different subsets of PIP and therefore neither alone is sufficient.
Additionally, only STOPP/START includes the START component, which detects prescribing omissions - clinically indicated medications that were never prescribed. Studies have found prescribing omissions in up to 44% of elderly patients, the most common being omissions in cardiovascular, bone health, and anticoagulation therapy [8].

6. The OPERAM Trial - STOPP/START in Practice

Blum et al. (2021) [10], in the landmark OPERAM cluster RCT across four European countries (n=2,008 patients aged ≥70 with multimorbidity and polypharmacy), found that 86.1% of older inpatients had inappropriate prescribing, with a mean of 2.75 STOPP/START recommendations per patient. A pharmacotherapy optimization intervention using STOPP/START reduced PIP in 62.2% of patients. While the primary outcome of drug-related hospital admissions was not significantly reduced, the trial provided robust real-world validation of STOPP/START as an effective inpatient screening tool.

7. Clinical Impact of Medication Review and Deprescribing

Carollo et al. (2024) [11] in a systematic review and meta-analysis of 30 studies found that medication review and deprescribing in older inpatients was associated with a statistically significant 8% reduction in hospital readmissions (HR 0.92, 95% CI 0.85-0.99), with no significant effect on mortality. The review emphasized that integration of thorough medication review protocols in hospital settings can improve post-discharge outcomes and reduce healthcare costs.
Zhou et al. (2023) [12] similarly confirmed in a meta-analysis that structured deprescribing interventions guided by PIM screening tools significantly reduced PIM use and improved clinical outcomes in elderly patients.

8. Need for Local Inpatient Data

Despite growing global evidence, the majority of existing studies originate from Western countries. Prescribing patterns, drug availability, disease profiles, and healthcare infrastructure differ considerably in developing countries. There is a recognized gap in inpatient-specific, region-specific medication chart review data using both Beers and STOPP/START criteria simultaneously, making the present study both original and clinically relevant.

  1. Age <60 years - Patients below the defined elderly threshold.
  2. Short stay - Patients admitted for less than 24 hours (e.g., day-care procedures, short observation stays) as complete prescribing data may not be available.
  3. Palliative / end-of-life care patients - Patients admitted for terminal/comfort care only, as PIM criteria are generally not applicable in hospice or end-of-life settings (per AGS Beers Criteria guidance).
  4. Incomplete medical records - Patients with missing or illegible medication charts, unclear diagnoses, or incomplete clinical data that prevents accurate PIM assessment.
  5. ICU patients (optional, depending on study design) - Patients admitted to the Intensive Care Unit may be excluded as ICU prescribing follows different protocols and the criteria may not be directly applicable in critical care settings.
  6. Post-operative patients on short-term medications only - Patients prescribed only perioperative drugs (e.g., post-surgical analgesics, antibiotics) without any chronic medications, as the criteria are primarily intended for ongoing drug therapy.
  7. Patients transferred from other hospitals mid-stay - If complete prior medication history is unavailable, accurate chart review cannot be performed.
  8. Patients with no chronic medications - Patients admitted for acute conditions with no long-term medications, as most PIM criteria apply to regularly used drugs.
  9. Repeated admissions of the same patient - To avoid duplication, only the first admission during the study period is included for each patient.

Give methodology for this study (prospective observational study)

Methodology


1. Study Design

A prospective observational study conducted in the inpatient wards of a tertiary care teaching hospital.

2. Study Setting

  • Department of Pharmacology / Clinical Pharmacy in collaboration with the Department of General Medicine and other specialty wards.
  • Tertiary care hospital attached to a medical college.
  • All inpatient wards including General Medicine, Cardiology, Neurology, Nephrology, Endocrinology, Orthopedics, and Surgery.

3. Study Duration

  • Total study period: 12 months (can be adjusted to 6-18 months based on sample size requirements)
  • Patient enrollment period: After obtaining Institutional Ethics Committee (IEC) approval

4. Study Population

All elderly patients (aged ≥60 years) admitted to the inpatient wards of the study hospital during the study period who fulfill the inclusion and exclusion criteria.

5. Sample Size

Sample size is calculated using the formula for prevalence studies:
n = Z² × P × (1-P) / d²
Where:
  • Z = 1.96 (at 95% confidence interval)
  • P = expected prevalence of PIP (based on previous studies, approximately 40-50%)
  • d = allowable error (10% or 0.1)
Example calculation:
  • n = (1.96)² × 0.45 × 0.55 / (0.1)²
  • n = 3.84 × 0.2475 / 0.01
  • n ≈ 95 patients (minimum); typically rounded up to 100-150 patients to account for dropouts and incomplete records.
(Exact sample size to be finalized based on institutional guidance and IEC recommendations)

6. Sampling Method

Consecutive sampling - All eligible elderly inpatients admitted during the study period who fulfill inclusion criteria will be enrolled until the required sample size is achieved.

7. Data Collection

a) Source of Data

  • Patient medication charts (inpatient drug prescription sheets)
  • Case records / medical files
  • Laboratory investigation reports
  • Nursing notes and clinical notes

b) Data Collection Tool

A pre-designed, validated patient data collection form (proforma) will be used, capturing:
ParameterDetails Collected
Demographic dataName (coded), age, sex, ward, date of admission
Clinical dataPrimary diagnosis, co-morbidities, duration of hospital stay
Medication dataName of drug, dose, frequency, route, duration, indication
Number of medicationsTotal drugs prescribed per patient
Polypharmacy≥5 drugs (yes/no)
Lab valuesRenal function (serum creatinine, eGFR), liver function, electrolytes - as required by the criteria

c) Process of Data Collection

  1. Eligible patients will be identified daily from ward admission registers.
  2. Informed written consent will be obtained from the patient or caregiver.
  3. Demographic and clinical details will be recorded from case sheets.
  4. All medications prescribed during the hospital stay will be noted from the medication charts.
  5. Relevant laboratory parameters will be recorded from investigation reports.

8. Application of Screening Tools

a) Beers Criteria (AGS 2023 Update)

Each patient's medication list will be reviewed against the 2023 AGS Beers Criteria, which consists of five tables:
  • Table 1: Medications to avoid in older adults regardless of condition
  • Table 2: Medications to avoid based on drug-disease/drug-syndrome interactions
  • Table 3: Medications to be used with caution
  • Table 4: Potentially clinically important drug-drug interactions to avoid
  • Table 5: Medications to avoid or reduce dose based on kidney function
Each PIM identified will be recorded with the drug name, reason flagged, and quality of evidence.

b) STOPP/START Criteria (Version 3, 2023)

The same medication list will be independently reviewed using STOPP/START Version 3, which includes:
  • 133 STOPP criteria - identifying drugs that should potentially be stopped (PIMs)
  • 57 START criteria - identifying drugs that should potentially be started (Prescribing Omissions / PPOs)
Criteria are organized by physiological system:
  • Cardiovascular, CNS/neurological, Renal, Gastrointestinal, Respiratory, Musculoskeletal, Endocrine, Urological, Analgesics, Anticoagulants, etc.
Each PIM or PPO identified will be recorded with the applicable criterion number, drug involved, and clinical reason.

9. Assessment and Analysis of PIMs

  • Each prescription will be reviewed independently using both tools.
  • PIMs identified by Beers criteria alone, STOPP/START alone, or both will be categorized separately.
  • Prescribing omissions (START criteria) will be listed separately.
  • Drug classes most commonly involved will be identified.
  • Agreement between the two tools will be assessed using Cohen's Kappa coefficient.

10. Statistical Analysis

All data will be entered in Microsoft Excel and analyzed using SPSS (version 25.0) or GraphPad Prism.
Statistical TestPurpose
Descriptive statisticsMean ± SD for continuous variables; frequency and percentage for categorical variables
Chi-square testAssociation between categorical variables (e.g., gender and PIM occurrence)
Independent t-test / Mann-Whitney U testComparison of means (e.g., number of PIMs vs. number of drugs)
Pearson / Spearman correlationCorrelation between number of drugs and number of PIMs
Logistic regressionIdentifying independent predictors of PIM occurrence (age, sex, polypharmacy, number of diagnoses)
Cohen's Kappa (κ)Agreement between Beers and STOPP/START criteria
Statistical significance will be set at p < 0.05.

11. Ethical Considerations

  • Approval will be obtained from the Institutional Ethics Committee (IEC) before study commencement.
  • Written informed consent will be obtained from all patients or their legal guardians.
  • Patient data will be kept strictly confidential and coded to maintain anonymity.
  • No intervention will be made in the patient's treatment - this is a purely observational study.
  • Data will be used solely for research purposes.
  • The study will adhere to the Declaration of Helsinki and ICMR guidelines for ethical conduct of research.

Indian and Global Scenario - Need for Study


Global Scenario

The world is undergoing a rapid demographic transition. According to the United Nations, the global population aged ≥60 years is expected to double from 1 billion in 2019 to over 2.1 billion by 2050. This ageing population carries a disproportionately high burden of chronic non-communicable diseases, driving the widespread use of multiple medications simultaneously - a condition termed polypharmacy.
Globally, the prevalence of PIM use is alarmingly high. Tian et al. (2023) [1], in a systematic review and meta-analysis of 94 studies involving nearly 371 million older adults from 17 countries, reported a pooled global PIM prevalence of 36.7% (95% CI 33.4%-40.0%). The burden was highest in Africa (47%) and South America (46.9%), while Asia reported 37.2%. Importantly, PIM use was highest in low-income regions and showed a steadily increasing trend over two decades, signaling a growing global public health concern.
Hospitalized elderly patients carry the greatest risk. Mekonnen et al. (2021) [2] in a meta-analysis of 63 inpatient studies demonstrated that PIP was associated with:
  • 91% increased odds of ADE-related hospital admissions
  • 60% increased odds of functional decline
  • 26% increased odds of adverse drug reactions
  • Consistent association with falls and increased length of stay
A 2026 meta-analysis by Muzzarelli et al. [3] further confirmed that PIMs identified by STOPP/START criteria were linked to a 1.84-fold increased risk of rehospitalization in older patients, establishing PIM screening as a critical inpatient safety measure.
The WHO's 3rd Global Patient Safety Challenge - Medication Without Harm has specifically identified elderly patients as a high-risk group and has called for a 50% reduction in medication-related harm globally, making systematic PIM screening in hospitals a direct regulatory and policy priority.

Indian Scenario

India is home to one of the fastest-growing elderly populations in the world. As per census projections, the elderly population (aged ≥60 years) in India constituted approximately 10.1% of the total population and is expected to double by 2050. States like Kerala, Tamil Nadu, and Himachal Pradesh already have a higher proportion of elderly residents exceeding 12-14%.
The Indian elderly population faces a dual burden - widespread chronic diseases (hypertension, diabetes, cardiovascular disease, chronic kidney disease) combined with a healthcare system that historically lacked structured geriatric pharmacotherapy guidelines. This creates fertile ground for polypharmacy and inappropriate prescribing.
Sharma et al. (2021) in a first-of-its-kind systematic review and meta-analysis of 27 Indian studies (11,649 participants) [4] reported:
  • Pooled prevalence of polypharmacy: 49% (95% CI 42-56%)
  • Hyperpolypharmacy (≥10 drugs): 31% (95% CI 21-40%)
  • Pooled prevalence of PIM use: 28% (95% CI 24-32%)
  • PIM prevalence was highest in South India (32%) and West India (33%)
  • Polypharmacy was more prevalent in outpatient settings (57%), while hyperpolypharmacy was higher in inpatient settings (37%)
Indian-specific studies from tertiary care hospitals have reported even higher rates:
  • Chinthalapudi et al. (2022) [5] in a retrospective analysis of 402 elderly inpatients at a South Indian tertiary hospital using Beers Criteria 2019 found:
    • PIM prevalence of 54% (caution category) and 45% (avoid category)
    • Most common PIMs: aspirin, diuretics, long-acting sulfonylureas, PPIs
    • Increasing age, polypharmacy, and ≥3 drugs in history were significant predictors (p<0.05)
  • Syed et al. (2026) [6] in a cross-sectional study of 597 hospitalized older adults in Southern India comparing Beers, STOPP, and FORTA criteria reported an extraordinarily high PIM prevalence of 99.33% by Beers and 99.16% by STOPP, with a mean of 3.89 PIMs per patient by Beers criteria - highlighting that inappropriate prescribing is nearly universal in Indian inpatient settings.
  • A 2024 Indian community study (Nature Scientific Reports) using STOPP/START v3 in 600 elderly adults across six Indian cities found PIM prevalence of 28.8% and prescribing omissions in 20.3% of patients, confirming that both overuse and underuse of medications are significant problems.
Additional Indian-specific challenges include:
  • Irrational prescribing culture - multiple studies document overprescribing driven by commercial incentives
  • Limited clinical pharmacist integration in most Indian hospitals
  • Absence of standardized geriatric prescribing guidelines at national level
  • Limited awareness among clinicians about Beers and STOPP/START criteria, particularly in tier-2 and tier-3 cities
  • Applicability gap - Beers Criteria is designed for North America; STOPP/START for Europe. Few studies have validated their combined use specifically in the Indian inpatient context

Summary

ParameterGlobalIndia
Elderly population growthDoubling by 2050Expected to double by 2050; currently ~10.1%
PIM prevalence36.7% globally (meta-analysis, 2023)28% pooled (meta-analysis); up to 99% in inpatient studies
Polypharmacy prevalenceRising worldwide49% in elderly Indians (meta-analysis)
Inpatient PIM consequences91% increased ADR admissions; 1.84x rehospitalizationHigh DDI risk; falls; prolonged stay
Criteria applicabilityBeers (USA), STOPP/START (Europe)Limited Indian-specific validation data
Clinical pharmacist roleEstablished in WestLargely absent in most Indian hospitals
The above data clearly demonstrates that PIP is a highly prevalent, clinically significant, yet preventable problem in both the global and Indian context. Despite this, inpatient-specific medication chart review studies using both Beers and STOPP/START criteria simultaneously in the Indian setting remain sparse. The present study directly addresses this gap and will generate locally applicable, policy-relevant evidence for improving medication safety in hospitalized elderly patients.

Need for Study


The global elderly population (≥60 years) is expanding rapidly and is projected to double to 2.1 billion by 2050. This demographic shift has led to a parallel rise in multi-morbidity, polypharmacy, and medication-related harm. Globally, a systematic review and meta-analysis of 94 studies involving 371 million older adults (Tian et al., 2023) [1] reported a pooled PIM prevalence of 36.7%, with the highest burden in low- and middle-income regions, including Asia (37.2%). PIP in hospitalized elderly patients is associated with 91% increased odds of ADE-related admissions, 60% increased functional decline, and a 1.84-fold increased risk of rehospitalization (Mekonnen et al., 2021 [2]; Muzzarelli et al., 2026 [3]).
In India, the elderly currently constitute 10.1% of the total population and this proportion is expected to double by 2050. A systematic review and meta-analysis of 27 Indian studies (Sharma et al., 2021) [4] reported a pooled polypharmacy prevalence of 49% and PIM prevalence of 28% among older Indians, with inpatient settings recording even higher hyperpolypharmacy rates of 37%. Indian inpatient studies have reported alarmingly high PIM rates - Chinthalapudi et al. (2022) [5] found PIM prevalence of 45-54% in a South Indian tertiary hospital, while Syed et al. (2026) [6] reported PIM rates as high as 99% by both Beers and STOPP criteria among hospitalized Indian elderly, with the number of medications being the strongest independent predictor.
Despite this burden, several critical gaps persist in the Indian context:
  1. Applicability gap - The Beers Criteria is designed for North America and STOPP/START for Europe. Their combined use in Indian inpatient settings has rarely been studied, yet both tools detect different subsets of PIP (kappa as low as 0.093), making their simultaneous use essential for a complete picture.
  2. Prescribing omissions underrecognized - The START component, which identifies clinically indicated but un-prescribed medications (PPOs), is frequently omitted in Indian studies, leaving a significant dimension of PIP unaddressed.
  3. Limited inpatient-specific data - Most Indian studies are community-based or outpatient-focused. Prospective medication chart review studies in inpatient wards of tertiary care hospitals - where prescribing complexity is highest - remain sparse.
  4. No structured screening in practice - Despite the high burden, the majority of Indian hospitals lack a systematic, criteria-based medication review process for elderly inpatients at admission or discharge, with no integration of clinical pharmacy services.
  5. Policy and guideline gap - India lacks national geriatric prescribing guidelines. Local inpatient data is essential to inform institutional prescribing policies, clinical pharmacist-physician collaboration, and training programs for clinicians.
The WHO Medication Without Harm global patient safety initiative specifically calls for a 50% reduction in medication-related harm in high-risk groups, including the elderly, further underscoring the urgency of this work.
A prospective medication chart review study using both Beers Criteria (2023) and STOPP/START Criteria (Version 3, 2023) in elderly inpatients will therefore address these existing gaps by providing current, locally applicable prevalence data, identifying the most common drug classes involved, detecting prescribing omissions, comparing tool performance in the Indian context, and laying the foundation for targeted interventions to reduce PIP and improve medication safety in hospitalized elderly patients.

Puig et al. (2024) in a multicenter retrospective study of 4,183 elderly inpatients (aged ≥75) across 16 hospitals in Spain, reported a PIM prevalence of 23.5% using Beers, STOPP-START, EU-PIM and PRISCUS criteria combined. Benzodiazepines accounted for 70% of all PIMs. The study noted that 35% of PIMs were initiated before hospital admission and were not withdrawn during the stay, underlining the need for inpatient medication chart review. 5.Blum et al. (2021) in the landmark OPERAM cluster RCT across four European countries (n=2,008 patients aged ≥70 with multimorbidity and polypharmacy), found that 86.1% of older inpatients had inappropriate prescribing, with a mean of 2.75 STOPP/START recommendations per patient. A pharmacotherapy optimization intervention using STOPP/START reduced PIP in 62.2% of patients. While the primary outcome of drug-related hospital admissions was not significantly reduced, the trial provided robust real-world validation of STOPP/START as an effective inpatient screening tool. 6.Carollo et al. (2024) in a systematic review and meta-analysis of 30 studies found that medication review and deprescribing in older inpatients was associated with a statistically significant 8% reduction in hospital readmissions (HR 0.92, 95% CI 0.85-0.99), with no significant effect on mortality. The review emphasized that integration of thorough medication review protocols in hospital settings can improve post-discharge outcomes and reduce healthcare costs.

What Happened in 2025 (Not a Full Update)

In July 2025, the AGS released a companion document titled:
"Alternative Treatments to Selected Medications in the 2023 AGS Beers Criteria®" Published in J Am Geriatr Soc. 2025. PMID: 40697073
This is not a new Beers Criteria update. It is a supplementary resource that:
  • Lists safer pharmacologic AND non-pharmacologic alternatives for each PIM in the 2023 Beers Criteria
  • Helps clinicians know what to prescribe instead after stopping a PIM
  • Replaces the previous Alternatives List from 2015

For Your Study

The 2023 AGS Beers Criteria® remains the latest and most current version as of June 2026. You should cite it as:
By the 2023 American Geriatrics Society Beers Criteria® Update Expert Panel. American Geriatrics Society 2023 updated AGS Beers Criteria® for potentially inappropriate medication use in older adults. J Am Geriatr Soc. 2023;71(7):2052-81. PMID: 37139824
The next full update is expected around 2026-2027 based on the AGS's regular 4-year update cycle, but has not been published yet as of today.

Can you give sample size for this study

Sample Size Calculation


Formula Used

For a prevalence-based cross-sectional / observational study, the standard formula is:
$$n = \frac{Z^2 \times P \times (1-P)}{d^2}$$
Where:
  • n = required sample size
  • Z = Z-value at desired confidence interval
  • P = expected prevalence of PIP in elderly inpatients (from previous studies)
  • d = allowable margin of error (absolute precision)

Values Used

ParameterValueJustification
Z1.9695% Confidence Interval (standard)
P0.45 (45%)Based on Chinthalapudi et al. (2022) - Indian tertiary care hospital reported 45% PIM prevalence using Beers Criteria 2019 [PMID: 33902417]
d0.10 (10%)Allowable margin of error (±10%) - standard for prevalence studies

Calculation

$$n = \frac{(1.96)^2 \times 0.45 \times (1 - 0.45)}{(0.10)^2}$$
$$n = \frac{3.8416 \times 0.45 \times 0.55}{0.01}$$
$$n = \frac{3.8416 \times 0.2475}{0.01}$$
$$n = \frac{0.9508}{0.01}$$
$$n = **95.1 \approx 96 \text{ patients}$$

With 10% Non-Response / Dropout Correction

$$n_{adjusted} = \frac{96}{1 - 0.10} = \frac{96}{0.90} = 106.7 \approx \textbf{107 patients}$$

Final Sample Size

Minimum sample size = 100-110 patients Rounded up to n = 100 (or n = 120 for better precision and to account for incomplete records)

Alternative Calculations Using Different Prevalence Estimates

Reference StudyCountryPrevalence Used (P)Calculated n (d=10%)
Chinthalapudi et al., 2022 [PMID: 33902417]India (tertiary care)45%96
Syed et al., 2026 [PMID: 40470955]India (hospital)99%4 (very high P → small n, but not representative)
Tian et al., 2023 [PMID: 37531105]Global meta-analysis36.7%89
Puig et al., 2024 [PMID: 39350081]Spain (inpatients)23.5%72
Recommended (P = 45%)India - conservative45%96 → 107 with dropout

Recommended Final Sample Size for Proposal

n = 100 patients (minimum) Preferred: n = 150 patients - to allow for:
  • Subgroup analysis (by age group, sex, ward, number of drugs)
  • Logistic regression analysis (requires ≥10 events per variable)
  • Incomplete records and dropout (~10-15%)
  • Adequate statistical power for Cohen's Kappa comparison

Write-up for Proposal (Ready to Use)

"The sample size was calculated using the formula n = Z²P(1-P)/d², where Z = 1.96 (at 95% confidence interval), P = 0.45 (expected prevalence of PIP based on Chinthalapudi et al., 2022, from a South Indian tertiary care hospital), and d = 0.10 (margin of error). The calculated minimum sample size was 96 patients. After adding a 10% correction for incomplete records and dropouts, the final required sample size was approximately 107 patients. A sample of 100-150 elderly inpatients will be enrolled over the study period to ensure adequate statistical power for subgroup analyses."

Reference for Sample Size Justification

  • Chinthalapudi SS et al. Prevalence and predictors of PIM use among elderly patients using updated Beers Criteria 2019. Curr Drug Saf. 2022;17(3):248-55. PMID: 33902417

Need help with inclusion/exclusion criteria refinement based on sample size?

Refined Inclusion & Exclusion Criteria Based on Sample Size (n = 100-150)


Key Principle

With a target of 100-150 patients over 12 months in a tertiary care hospital, the criteria must be broad enough to enroll sufficient patients yet specific enough to maintain study quality and validity.

INCLUSION CRITERIA (Refined)

1. Age

  • Patients aged ≥60 years
  • (Rationale: Indian definition of elderly is ≥60 years per National Policy for Older Persons, India. Using ≥65 years would reduce pool by ~30-40%, risking under-enrollment in 12 months)

2. Admission Type

  • Admitted as inpatients for ≥24 hours
  • (Rationale: Ensures at least one complete inpatient medication chart is available for review. Patients staying <24 hours may not have full medication data)

3. Number of Medications

  • Prescribed ≥2 medications during hospital stay
  • (Rationale: A minimum of 2 drugs is required to assess drug-drug interactions under Beers Table 4. Using ≥5 drugs would be too restrictive and reduce sample significantly; ≥2 captures the broader PIM picture)

4. Ward Coverage

  • Patients admitted to any inpatient ward - General Medicine, Cardiology, Neurology, Nephrology, Endocrinology, Orthopedics, General Surgery
  • (Rationale: Broad ward inclusion ensures diverse prescribing patterns and avoids selection bias; also protects against under-enrollment if one ward has low admissions)

5. Documentation

  • Patients with complete and legible medication charts, case records, and at least basic laboratory data (serum creatinine / renal function mandatory; others as available)
  • (Rationale: Renal function is required by both Beers Table 5 and STOPP renal criteria. Without it, a significant number of criteria cannot be applied)

6. Consent

  • Patients or their legally acceptable representatives willing to give written informed consent
  • (Rationale: For prospective studies, consent is mandatory per ICMR guidelines and Declaration of Helsinki)

EXCLUSION CRITERIA (Refined)

1. Age <60 years

  • Strictly excluded
  • (Rationale: Both Beers and STOPP/START criteria are validated for adults ≥60-65 years only)

2. Hospital Stay <24 hours

  • Emergency visits, day-care procedures, OPD consultations
  • (Rationale: Insufficient time for inpatient medication prescribing to be documented)

3. Palliative / End-of-Life / Hospice Care

  • Patients admitted solely for terminal care or comfort measures
  • (Rationale: AGS Beers Criteria 2023 explicitly excludes hospice and end-of-life care settings from applicability)

4. Incomplete Records

  • Missing medication charts, unreadable prescriptions, or unavailable serum creatinine
  • (Rationale: Cannot apply renal-based Beers/STOPP criteria without renal function data. Incomplete records reduce data quality and validity)

5. ICU / Critical Care Patients (Optional - study-specific decision)

  • Patients admitted to ICU / HDU throughout their stay
  • (Rationale: ICU prescribing follows resuscitation protocols that differ fundamentally from chronic disease management. Inclusion may confound PIM analysis. However, if sample size is at risk, patients transferred OUT of ICU to wards may be included after 24 hours of ward stay)

6. Psychiatric Inpatients (if separate psychiatry ward exists)

  • Patients admitted to dedicated psychiatry wards
  • (Rationale: Psychiatric prescribing (antipsychotics, mood stabilizers) follows different guidelines and may skew PIM rates. Include only if psychiatry ward is part of same general hospital and sample size needs protection)

7. Repeat Admissions

  • If the same patient is admitted more than once during the study period, only the first admission is included
  • (Rationale: Prevents duplication bias in prevalence estimates)

8. Patients on Only Single Drug

  • Patients prescribed only 1 medication throughout stay
  • (Rationale: Drug-drug interaction criteria cannot be assessed; very limited PIM analysis possible)

HOW CRITERIA AFFECT SAMPLE SIZE

CriterionEffect on EnrollmentRecommendation
Age ≥60 vs ≥65≥60 gives ~20-30% more patientsUse ≥60 for Indian context
≥2 drugs vs ≥5 drugs≥2 gives 40-50% more eligible patientsUse ≥2 to protect sample size
All wards vs medicine onlyAll wards doubles eligible poolInclude all wards
Exclude ICU entirelyReduces pool by ~10-15%Exclude only pure ICU stays; include post-ICU ward transfers
Exclude psychiatryReduces pool by ~5-10%Exclude if separate ward
Exclude incomplete recordsReduces pool by ~10%Minimize by training data collectors
24-hour stay cutoffExcludes <5% of admissionsKeep 24-hour cutoff

SAMPLE SIZE PROTECTION STRATEGIES

If enrollment is slower than expected:
  1. Extend study period from 12 to 18 months
  2. Add more wards (e.g., include oncology, respiratory medicine)
  3. Lower minimum drugs threshold to ≥1 medication (with a note in limitations)
  4. Include post-ICU transfers to general ward after stabilization
  5. Allow same-patient repeat admissions with a minimum 30-day gap (with sensitivity analysis)

FINAL REFINED CRITERIA - READY FOR PROPOSAL

How to calculate the degree of agreement between two tools

Degree of Agreement Between Beers Criteria and STOPP/START Criteria


The Statistical Test Used: Cohen's Kappa (κ)

The degree of agreement between two tools (Beers Criteria and STOPP criteria) is measured using Cohen's Kappa coefficient (κ), which measures agreement beyond chance.

STEP 1: Understand the Concept

For each patient, both tools give a binary result:
  • PIM Present (Yes) or PIM Absent (No)
So for each patient, there are 4 possible combinations:
STOPP: PIM YesSTOPP: PIM NoTotal
Beers: PIM Yesa (Both agree - Yes)b (Beers Yes, STOPP No)a+b
Beers: PIM Noc (Beers No, STOPP Yes)d (Both agree - No)c+d
Totala+cb+dN
Where:
  • a = both tools identified PIM (agreement - positive)
  • d = both tools found no PIM (agreement - negative)
  • b = Beers found PIM but STOPP did not (disagreement)
  • c = STOPP found PIM but Beers did not (disagreement)

STEP 2: Cohen's Kappa Formula

$$\kappa = \frac{P_o - P_e}{1 - P_e}$$
Where:
  • P₀ = Observed agreement (proportion of cases where both tools agree)
  • P_e = Expected agreement by chance

Calculate P₀ (Observed Agreement):

$$P_o = \frac{a + d}{N}$$

Calculate P_e (Expected Agreement by Chance):

$$P_e = \frac{(a+b)(a+c)}{N^2} + \frac{(c+d)(b+d)}{N^2}$$

STEP 3: Worked Example

Suppose your study has 100 patients:
STOPP: PIM YesSTOPP: PIM NoTotal
Beers: PIM Yes40 (a)15 (b)55
Beers: PIM No20 (c)25 (d)45
Total6040100

Step 3a: Calculate P₀

$$P_o = \frac{40 + 25}{100} = \frac{65}{100} = 0.65$$

Step 3b: Calculate P_e

$$P_e = \frac{(55 \times 60)}{100^2} + \frac{(45 \times 40)}{100^2}$$ $$P_e = \frac{3300}{10000} + \frac{1800}{10000} = 0.33 + 0.18 = 0.51$$

Step 3c: Calculate Kappa

$$\kappa = \frac{0.65 - 0.51}{1 - 0.51} = \frac{0.14}{0.49} = \textbf{0.286}$$

STEP 4: Interpret Kappa Value

Kappa (κ) ValueStrength of Agreement
< 0.00Poor (less than chance)
0.00 - 0.20Slight
0.21 - 0.40Fair
0.41 - 0.60Moderate
0.61 - 0.80Substantial
0.81 - 1.00Almost Perfect
(Landis & Koch, 1977 scale - most widely used in medicine)
In published studies comparing Beers and STOPP:
  • Agreement is typically κ = 0.09 to 0.25 (Slight to Fair)
  • This low agreement is the key finding that justifies using both tools together

STEP 5: Additional Agreement Measures

Besides Kappa, report these for completeness:

1. Percent Overall Agreement

$$% \text{ Agreement} = \frac{a + d}{N} \times 100$$

2. Sensitivity and Specificity

(If one tool is taken as reference/gold standard)
MeasureFormula
Sensitivitya / (a+c) × 100
Specificityd / (b+d) × 100
PPVa / (a+b) × 100
NPVd / (c+d) × 100

3. McNemar's Test

Tests whether the proportion of PIMs detected differs significantly between the two tools:
$$\chi^2 = \frac{(b - c)^2}{b + c}$$
  • p < 0.05 = statistically significant difference in detection rates between tools
  • Use this to compare how many PIMs each tool found, not just agreement

STEP 6: How to Do This in SPSS

Method 1: SPSS (Crosstabs + Kappa)

Analyze → Descriptive Statistics → Crosstabs
→ Row: Beers_PIM (Yes/No)
→ Column: STOPP_PIM (Yes/No)
→ Statistics → tick "Kappa"
→ OK
SPSS will give:
  • Kappa value
  • Standard Error
  • Asymptotic Significance (p-value)

Method 2: SPSS (McNemar's Test)

Analyze → Descriptive Statistics → Crosstabs
→ Statistics → tick "McNemar"
→ OK

  • Get Kappa + 95% CI instantly

STEP 7: How to Report in Your Study

"The degree of agreement between the Beers Criteria (2023) and STOPP criteria (Version 3) in identifying PIMs was assessed using Cohen's Kappa coefficient (κ). A κ value of ______ (95% CI: ______ to ______) was obtained, indicating ______ [slight/fair/moderate] agreement between the two tools (p = ______).

Can I write department general medicine including geriatric medicine ward?

Yes, absolutely. This is actually a better and more accurate way to write it. Here is the reasoning and how to phrase it:

Recommended Wording

For Study Setting (in Methodology):

"The study will be conducted in the inpatient wards of a tertiary care teaching hospital, primarily in the Department of General Medicine including the Geriatric Medicine Ward, with additional enrollment from allied specialty wards such as Cardiology, Neurology, Nephrology, and Endocrinology, as applicable."

For Study Population (in Methodology):

"All elderly patients (aged ≥60 years) admitted to the Department of General Medicine including the Geriatric Medicine Ward and other inpatient wards of [Hospital Name], who fulfill the inclusion criteria, will be enrolled during the study period."

Why This Phrasing is Better

ReasonExplanation
Clinically accurateGeneral Medicine wards in Indian teaching hospitals typically include or overlap with Geriatric Medicine beds
Maximizes enrollmentGeriatric Medicine ward is the highest-yield source of elderly patients with polypharmacy - essential for reaching n=100-150
Study validityPatients in Geriatric Medicine ward have the highest burden of multi-morbidity and polypharmacy - directly relevant to study objectives
Accepted in literatureMost Indian PIP studies (including Chinthalapudi et al., Syed et al.) were conducted in General Medicine / Geriatric wards of tertiary hospitals
IEC approvalEthics committees prefer clearly defined study settings - naming both General Medicine and Geriatric Medicine ward makes the scope precise

How to Write It in Different Sections

1. Title Page / Protocol Cover

Study Setting: Department of General Medicine including Geriatric Medicine Ward, [Hospital Name]

2. Methodology - Study Setting

"This prospective observational study will be conducted in the Department of General Medicine, including the dedicated Geriatric Medicine Ward, at [Hospital Name], a tertiary care teaching hospital. Additional patients will be enrolled from allied specialty wards (Cardiology, Nephrology, Neurology, Endocrinology) where elderly inpatients with multiple co-morbidities and polypharmacy are commonly admitted."

3. Inclusion Criteria

"Patients aged ≥60 years admitted to the Department of General Medicine (including Geriatric Medicine Ward) and allied specialty wards of [Hospital Name]."

Additional Tip

If your hospital does not have a separate Geriatric Medicine Ward, write it as:
"Department of General Medicine (Geriatric patients)"
or simply:
"Department of General Medicine and allied specialty inpatient wards"
This is perfectly acceptable and commonly used in Indian medical college hospital research protocols.

How to Write It in Your Protocol

"The sample size was calculated using the formula described by Lwanga and Lemeshow (WHO, 1991) [2], with the expected prevalence of potentially inappropriate prescribing (P = 45%) derived from Chinthalapudi et al. (2022) [1], a study conducted in a South Indian tertiary care hospital using the Beers Criteria 2019. At a 95% confidence interval (Z = 1.96) and 10% allowable error (d = 0.10), the minimum required sample size was calculated as 96 patients. Adding a 10% correction for incomplete records and dropouts, the final sample size was determined to be 107 patients, rounded to 100-150 patients for the study."
