KMTC Research Methods — Topic-by-Topic Summary Notes


TOPIC 1: Concepts of Research

What is Research? A systematic, controlled, empirical, and critical investigation of phenomena, guided by theory or hypotheses, about presumed relations among such phenomena.
Purposes of Research:
  • Describe phenomena (descriptive)
  • Explain cause-effect relationships (explanatory)
  • Predict outcomes
  • Control or improve practice
Characteristics of Good Research:
  • Systematic and organised
  • Empirical (evidence-based)
  • Objective and unbiased
  • Replicable
  • Ethical
Types of Research:
TypeDescription
Basic/PureBuilds knowledge; no immediate application
AppliedSolves practical problems (most health research)
QuantitativeNumerical data; statistics; objectivity
QualitativeNon-numerical; explores meanings, experiences
Mixed MethodsCombines quantitative and qualitative

TOPIC 2: Research Designs

Definition: The overall plan/strategy for answering the research question.

A. Descriptive Designs

  • Describe characteristics of a population or phenomenon
  • E.g., surveys, case studies, cross-sectional studies
  • No manipulation of variables

B. Observational Designs

DesignKey Feature
Cross-sectionalData collected at one point in time
Case-controlCompares cases vs. controls; looks backward
CohortFollows exposed vs. unexposed groups forward in time

C. Experimental Designs

  • Randomised Controlled Trial (RCT): Gold standard; random allocation to treatment/control
  • Quasi-experimental: No randomisation; natural groups
  • Pre-test / Post-test: Measures before and after intervention
Advantages and Disadvantages must be known for each — common exam question.

TOPIC 3: The Research Process

A step-by-step sequence:
  1. Identify a research problem
  2. Review existing literature
  3. Formulate objectives / hypothesis / research questions
  4. Choose research design
  5. Develop methodology (sampling, instruments)
  6. Collect data
  7. Analyse and interpret data
  8. Write and present findings
  9. Publish / disseminate

TOPIC 4: Identifying & Prioritising the Research Problem

Research Problem: A gap in knowledge or an unresolved issue in practice.
Sources of Research Problems:
  • Clinical observation, patient complaints
  • Literature gaps
  • Policy needs, community health issues
Criteria for a Good Research Problem (FINER):
  • Feasible (resources, time, skills available)
  • Interesting to the researcher
  • Novel (adds new knowledge)
  • Ethical
  • Relevant to health needs
Research Question vs. Hypothesis:
  • Research question: Open-ended (e.g., "What factors contribute to…?")
  • Hypothesis: A testable prediction (e.g., "There is a significant association between X and Y")
    • Null hypothesis (H₀): No effect / no difference
    • Alternative hypothesis (H₁): There is an effect / difference

TOPIC 5: Literature Review, Referencing & Citation

Purpose of Literature Review:
  • Shows existing knowledge
  • Justifies the study
  • Avoids duplication
  • Identifies gaps
Steps:
  1. Define search terms
  2. Search databases (PubMed, Google Scholar, WHO, MoH Kenya)
  3. Critically appraise sources
  4. Synthesise and write
Referencing Styles commonly used at KMTC: APA or Vancouver
APA Format (in-text): (Author, Year) Vancouver (in-text): Numbered superscripts [1]

TOPIC 6: Research Methodology & Protocol Development

Key Concepts:

Target Population: The entire group the researcher wants to study. Accessible Population: The portion realistically available. Sample: A subset of the population selected for study.

Sampling Methods:

TypeDescription
Simple randomEvery member has equal chance; lottery/random numbers
Stratified randomDivide into strata, then randomly sample each
SystematicSelect every nth person
ClusterRandomly select groups (clusters), study all within
PurposiveDeliberately select based on characteristics (qualitative)
ConvenienceUse available/accessible subjects
Sample Size Determination: Influenced by population size, expected prevalence, desired confidence level (usually 95%), and acceptable margin of error.

Instrument Development:

  • Questionnaire: Self-administered; closed or open-ended questions
  • Interview guide: Structured, semi-structured, or unstructured
  • Observation checklist
  • Document review guide
Validity: Does the instrument measure what it is supposed to measure?
  • Content validity, construct validity, criterion validity
Reliability: Does it give consistent results on repeated use?
  • Test-retest, inter-rater reliability

TOPIC 7: Data Collection, Processing, Analysis & Interpretation

Data Collection:

  • Primary data: Collected first-hand (interviews, questionnaires, observation)

STRUCTURED / LONG ANSWER QUESTIONS (Exam-style)


57. A clinical officer at a rural health facility notices that many diabetic patients miss their clinic appointments. She decides to conduct a study on this problem.
(a) Write a suitable research problem statement for this study. (2 marks) (b) State ONE research objective and ONE research hypothesis. (4 marks) (c) Identify the MOST appropriate research design and justify your choice. (3 marks) (d) Describe TWO sampling methods she could use and state which is preferable. (4 marks) (e) State THREE ethical considerations she must observe. (3 marks)
Model Answer: (a) "Despite available services, a high proportion of diabetic patients at [name] Health Centre miss scheduled follow-up appointments; the factors contributing to this are not documented."
(b) Objective: To determine factors associated with missed clinic appointments among diabetic patients at [name] Health Centre. Hypothesis H₀: There is no significant association between transportation cost and missed clinic appointments among diabetic patients.
(c) Cross-sectional descriptive design — it allows collection of data at one point in time, is quick, inexpensive, and suitable for identifying prevalence and associated factors in a clinic population.
(d) Simple random sampling (from clinic register) or systematic sampling (every nth patient). Systematic sampling is preferable given an ordered register — practical and efficient.
(e) Obtain informed consent; ensure confidentiality of patient information; obtain ethical approval from the institutional review committee.

58. Explain the difference between descriptive and inferential statistics. Give TWO examples of each and state when each type is used in health research. (10 marks)
Model Answer: Descriptive Statistics summarise and describe the main features of a dataset without drawing conclusions beyond the data itself.
  • Examples: Mean age of patients (e.g., mean = 45 years); frequency table showing percentage of males vs. females.
  • Used when: Presenting baseline characteristics of a study population; summarising survey findings.
Inferential Statistics use sample data to make inferences or draw conclusions about a larger population; involves hypothesis testing.
  • Examples: Chi-square test to test association between smoking and lung disease; t-test to compare mean blood glucose between two treatment groups.
  • Used when: Testing whether differences between groups are statistically significant; determining if findings can be generalised to the population.

KMTC Research Methods — 40 MCQs with Answers & Explanations


SECTION A: Concepts of Research

1. Which of the following BEST defines research?
  • A. Gathering information from the internet
  • B. A systematic, empirical and critical investigation aimed at discovering new knowledge
  • C. Reading journals and summarising findings
  • D. Asking experienced clinicians for their opinions
Answer: B Research is defined as a systematic, controlled, empirical and critical investigation of phenomena. It must be structured and evidence-based — not just information gathering.

2. A study conducted to solve an immediate practical problem in a health facility is called:
  • A. Basic research
  • B. Pure research
  • C. Applied research
  • D. Historical research
Answer: C Applied research is directed at solving specific real-world problems. Basic/pure research builds general knowledge without immediate application.

3. Which of the following is NOT a characteristic of good research?
  • A. It is replicable
  • B. It is based on personal bias
  • C. It is systematic
  • D. It is empirical
Answer: B Good research must be objective and free from personal bias. All other options — replicability, systematic approach, and empirical basis — are hallmarks of quality research.

4. Research that collects non-numerical data to understand human experiences and meanings is called:
  • A. Experimental research
  • B. Quantitative research
  • C. Qualitative research
  • D. Descriptive research
Answer: C Qualitative research explores attitudes, behaviours, and experiences through methods like interviews and focus groups. It produces non-numerical, narrative data.

5. The PRIMARY motivation for conducting health research is to:
  • A. Fulfil academic requirements
  • B. Improve patient care and health outcomes
  • C. Secure research funding
  • D. Publish papers in journals
Answer: B The ultimate goal of health research is to generate knowledge that improves clinical practice and patient outcomes, even when academic or funding requirements are also present.

SECTION B: Research Designs

6. A researcher selects 200 patients who have tuberculosis (cases) and 200 who do not (controls) to compare their past exposure to indoor smoke. This is a:
  • A. Cohort study
  • B. Cross-sectional study
  • C. Case-control study
  • D. Randomised Controlled Trial
Answer: C A case-control study starts with disease status (cases vs. controls) and looks BACKWARD to compare past exposures. It is ideal for rare diseases like TB.

7. A study that collects data from a population at a single point in time is called:
  • A. Longitudinal study
  • B. Cohort study
  • C. Cross-sectional study
  • D. Case-control study
Answer: C Cross-sectional studies are a "snapshot" — data collected at one moment. They can measure prevalence but cannot establish cause and effect.

8. The research design considered the GOLD STANDARD for testing the effectiveness of a new drug is:
  • A. Cross-sectional study
  • B. Cohort study
  • C. Case-control study
  • D. Randomised Controlled Trial (RCT)
Answer: D RCTs randomly allocate participants to treatment or control groups, eliminating selection bias. This makes them the most reliable design for testing interventions.

9. In a cohort study, participants are selected based on:
  • A. Whether they have the disease or not
  • B. Their exposure status (exposed vs. unexposed)
  • C. Convenience of access
  • D. Random allocation to treatment groups
Answer: B Cohort studies select participants according to exposure (e.g., smokers vs. non-smokers) then follow them forward in time to see who develops the disease.

10. Which study design is BEST suited for studying a rare disease?
  • A. RCT
  • B. Cross-sectional study
  • C. Case-control study
  • D. Cohort study
Answer: C Case-control studies are efficient for rare diseases because you start by identifying existing cases rather than waiting for the disease to develop in a large cohort.

11. A researcher tests a new nursing intervention on one group before and after implementation without a control group. This is:
  • A. A true experimental design
  • B. A quasi-experimental design
  • C. A case-control study
  • D. A cohort study
Answer: B True experimental designs require randomisation and a control group. Without these, the design is quasi-experimental — still useful but with lower internal validity.

SECTION C: Research Process & Problem Formulation

12. The FIRST step in the research process is:
  • A. Reviewing literature
  • B. Collecting data
  • C. Identifying a research problem
  • D. Writing the hypothesis
Answer: C You cannot review literature, design a study, or collect data until you have identified WHAT problem needs to be investigated. Problem identification always comes first.

13. According to the FINER criteria, "E" stands for:
  • A. Empirical
  • B. Ethical
  • C. Extensive
  • D. Explanatory
Answer: B FINER = Feasible, Interesting, Novel, Ethical, Relevant. A good research problem must not harm participants and must be approvable by an ethics committee.

14. "There is no significant difference in wound healing rates between patients dressed with honey and those dressed with normal saline." This statement is a:
  • A. Research question
  • B. Research objective
  • C. Alternative hypothesis
  • D. Null hypothesis
Answer: D The null hypothesis (H₀) always states there is NO effect, NO difference, or NO relationship. It is what the researcher attempts to disprove.

15. A specific, measurable statement predicting the expected relationship between variables is called:
  • A. Research problem
  • B. Research hypothesis
  • C. Research design
  • D. Research instrument
Answer: B A hypothesis is a testable prediction about the relationship between an independent variable and a dependent variable. It must be falsifiable.

16. Which of the following is the BEST example of a well-stated research problem?
  • A. "HIV is a serious disease in Africa"
  • B. "I want to study malnutrition"
  • C. "Despite supplementation programmes, 40% of children under 5 in Turkana remain stunted; contributing factors are unknown"
  • D. "How can we improve health in Kenya?"
Answer: C A good problem statement is specific, identifies a gap in knowledge, is measurable, and points toward a clear investigation. Options A, B, and D are vague and non-specific.

SECTION D: Literature Review & Referencing

17. The MAIN purpose of a literature review in a research proposal is to:
  • A. Demonstrate the researcher's reading ability
  • B. Identify gaps in existing knowledge and justify the study
  • C. Replace the methodology section
  • D. List all books available on the topic
Answer: B A literature review contextualises the study, shows what is already known, and — most importantly — identifies the gap that the new research will fill.

18. In APA referencing style, how is a source cited within the text?
  • A. [1]
  • B. (Author, Year)
  • C. Author [page number]
  • D. Superscript number¹
Answer: B APA uses the author-date format: e.g., (Mugenda, 2009). Vancouver style uses numbered citations [1] or superscripts. KMTC commonly uses APA.

19. A researcher combines results from multiple independent studies on the same topic using statistical methods. This process is called:
  • A. Systematic review
  • B. Literature review
  • C. Meta-analysis
  • D. Narrative review
Answer: C A meta-analysis pools quantitative data from multiple studies to produce a combined statistical estimate. A systematic review is the broader process; meta-analysis is its statistical component.

20. Presenting another person's work as your own without acknowledgement is:
  • A. Paraphrasing
  • B. Summarising
  • C. Referencing
  • D. Plagiarism
Answer: D Plagiarism is a serious academic and research offence. All ideas, quotes, and data taken from other sources must be cited, whether paraphrased or quoted directly.

SECTION E: Sampling Methods

21. A researcher selects every 10th patient from a clinic register of 500 patients. This sampling method is:
  • A. Simple random sampling
  • B. Stratified random sampling
  • C. Systematic sampling
  • D. Purposive sampling
Answer: C Systematic sampling selects every nth element from an ordered list. It is practical and easy to implement using registers or lists.

22. A researcher divides the study population into male and female groups, then randomly selects 50 from each group. This is:
  • A. Cluster sampling
  • B. Stratified random sampling
  • C. Systematic sampling
  • D. Convenience sampling
Answer: B Stratified random sampling divides the population into subgroups (strata) based on a characteristic (e.g., sex), then randomly samples from each stratum. It ensures representation of all subgroups.

23. In qualitative research, the sampling method that deliberately selects participants based on specific characteristics relevant to the study is:
  • A. Simple random sampling
  • B. Systematic sampling
  • C. Purposive sampling
  • D. Cluster sampling
Answer: C Purposive (judgmental) sampling is non-probability sampling where the researcher deliberately chooses participants who have the knowledge or experience relevant to the study — standard in qualitative research.

24. The term used to describe the ENTIRE group that a researcher wants to study is:
  • A. Sample
  • B. Strata
  • C. Target population
  • D. Study unit
Answer: C The target population is everyone the researcher wants to generalise findings to. The accessible population is the reachable subset. The sample is drawn from the accessible population.

25. Which sampling method gives every member of the population an EQUAL and INDEPENDENT chance of selection?
  • A. Convenience sampling
  • B. Purposive sampling
  • C. Simple random sampling
  • D. Snowball sampling
Answer: C Simple random sampling is the purest probability sampling method. A lottery or random number table ensures no bias in who gets selected.

26. The degree to which a research instrument measures what it is supposed to measure is called:
  • A. Reliability
  • B. Validity
  • C. Sensitivity
  • D. Precision
Answer: B Validity asks: "Are we measuring the right thing?" Reliability asks: "Do we get consistent results?" An instrument can be reliable without being valid, but not the reverse.

SECTION F: Data Collection & Analysis

27. Data collected by reviewing existing hospital records and reports is called:
  • A. Primary data
  • B. Raw data
  • C. Secondary data
  • D. Quantitative data
Answer: C Secondary data already exists and was collected for another purpose (e.g., hospital registers, MOH reports). Primary data is collected fresh by the researcher.

28. The process of assigning numerical codes to questionnaire responses before entering data into a computer is called:
  • A. Editing
  • B. Cleaning
  • C. Coding
  • D. Tabulation
Answer: C Coding converts categorical responses into numbers for software analysis (e.g., Male=1, Female=2). Editing checks for completeness; cleaning corrects errors after entry.

29. A set of scores: 5, 8, 8, 10, 12, 15, 20. The MODE is:
  • A. 10
  • B. 12
  • C. 8
  • D. 15
Answer: C The mode is the value that appears MOST frequently. The number 8 appears twice; all others appear once. Therefore mode = 8.

30. When data is heavily skewed, the BEST measure of central tendency to use is:
  • A. Mean
  • B. Standard deviation
  • C. Mode
  • D. Median
Answer: D The mean is pulled toward extreme values (outliers) in skewed data. The median (middle value) is resistant to skew and better represents the centre of a skewed distribution.

31. A statistical test used to determine whether there is a significant association between two categorical variables (e.g., gender and disease status) is:
  • A. t-test
  • B. ANOVA
  • C. Chi-square test
  • D. Pearson correlation
Answer: C Chi-square (χ²) tests associations between categorical variables. t-test compares means of two groups. ANOVA compares means of three or more groups. Pearson correlation measures linear relationships between continuous variables.

SECTION G: Statistics & Health Rates

32. A county has a mid-year population of 400,000. There were 8,000 live births during the year. The Crude Birth Rate is:
  • A. 10 per 1,000
  • B. 20 per 1,000
  • C. 40 per 1,000
  • D. 80 per 1,000
Answer: B CBR = (Live births ÷ Mid-year population) × 1,000 = (8,000 ÷ 400,000) × 1,000 = 20 per 1,000

33. The number of NEW cases of a disease occurring in a defined population during a specified period is called:
  • A. Prevalence
  • B. Incidence
  • C. Mortality rate
  • D. Case fatality rate
Answer: B Incidence = new cases over a period (measures RISK of developing disease). Prevalence = all existing cases at a point in time (measures BURDEN of disease).

34. In a study, the p-value obtained is 0.02. The correct interpretation is:
  • A. The null hypothesis is accepted
  • B. The result is not statistically significant
  • C. The result is statistically significant; reject the null hypothesis
  • D. The study has a 2% chance of being wrong
Answer: C When p < 0.05, the result is statistically significant — we reject the null hypothesis. The p-value is NOT the probability that the study is wrong; it is the probability of getting these results if H₀ were true.

35. 500 new malaria cases were reported in a population of 250,000 during one year. The incidence rate per 1,000 is:
  • A. 0.2
  • B. 2
  • C. 5
  • D. 20
Answer: B Incidence rate = (New cases ÷ Population at risk) × 1,000 = (500 ÷ 250,000) × 1,000 = 2 per 1,000

36. Statistics used to draw conclusions about a population based on data from a sample are called:
  • A. Descriptive statistics
  • B. Parametric statistics
  • C. Inferential statistics
  • D. Nominal statistics
Answer: C Inferential statistics (e.g., chi-square, t-test, ANOVA) allow generalisation from sample findings to the larger population. Descriptive statistics only summarise the data collected.

SECTION H: Research Ethics & Report Writing

37. The ethical principle that requires researchers to maximise benefits and minimise harm to participants is:
  • A. Justice
  • B. Autonomy
  • C. Beneficence

Short Answer Questions (SAQs)

9. Define research and state FOUR characteristics of good research. (5 marks)
Model Answer: Definition: Research is a systematic, controlled, empirical, and critical investigation of phenomena, guided by theory or hypotheses, about presumed relations among such phenomena.
Four characteristics:
  1. Systematic — follows a structured, planned process
  2. Empirical — based on observable evidence, not opinion
  3. Objective — free from personal bias
  4. Replicable — can be repeated by other researchers and yield similar results (Also acceptable: ethical, valid, reliable)

10. Distinguish between inductive and deductive reasoning in research. (4 marks)
Model Answer:
  • Inductive reasoning: Moves from specific observations to broad generalisations. Researcher collects data first, then develops a theory. Common in qualitative research. Example: Observing that several malnourished children come from households without latrines → concluding poor sanitation contributes to malnutrition.
  • Deductive reasoning: Starts with an existing theory or hypothesis, then collects data to test it. Common in quantitative research. Example: Hypothesising that exclusive breastfeeding reduces diarrhoea, then testing this in a study.

11. List FIVE types of research and give ONE example of each relevant to healthcare. (5 marks)
Model Answer:
TypeHealthcare Example
ExploratoryPreliminary study on factors affecting vaccine uptake in a new county
DescriptivePrevalence survey of hypertension in adults in Nairobi
AnalyticalCase-control study on risk factors for cervical cancer
PredictiveStudy predicting diabetes risk based on BMI and family history
Experimental/AppliedRCT testing a new wound dressing for diabetic foot ulcers

Application Question

12. A nurse at Kakamega County Hospital notices that many patients are readmitted within 30 days of discharge. She wants to investigate this problem.
(a) What type of research (by purpose) would be MOST appropriate to first explore this problem? Justify your answer. (3 marks) (b) What research approach (quantitative, qualitative, or mixed methods) would best capture both the rate of readmission AND patients' reasons for readmission? Explain. (3 marks)
Model Answer: (a) Exploratory research — because the problem is not well understood yet. There is no established theory about WHY readmissions are occurring, so an exploratory approach would first describe the scope of the problem and identify potential contributing factors before a more focused study is designed.
(b) Mixed methods — quantitative component would measure the readmission rate (numbers, percentages, demographics) while the qualitative component (interviews/focus groups) would explore patients' lived experiences, barriers to follow-up, and reasons for returning. Using only one approach would miss either the scale or the depth of the problem.

  1. Fabrication — inventing/making up data or results that were never collected
  2. Falsification — manipulating, altering, or omitting data to change research outcomes
  3. Plagiarism — using another person's ideas, data, or writing without proper attribution

Application Question (LAQ)

52. (Long Answer — 15 marks)
You are a final-year Clinical Medicine student at KMTC. You have been asked to write a research proposal on: "Factors associated with high defaulter rates among tuberculosis patients at a district hospital in Western Kenya."
(a) Write a suitable title, background, and problem statement for this proposal. (4 marks) (b) State ONE general objective and THREE specific objectives. (4 marks) (c) Describe the methodology you would use, including: design, population, sampling technique, sample size approach, and instrument. (5 marks) (d) State TWO ethical considerations relevant to this study. (2 marks)
Model Answer:
(a) Title: Factors Associated with Tuberculosis Treatment Default among Patients Attending [Name] District Hospital, Western Kenya: A Cross-Sectional Study
Background: Tuberculosis (TB) remains a major public health concern in Kenya, ranking among the top 10 causes of death. The WHO END TB Strategy targets treatment success rates of ≥90%. However, treatment default — defined as interruption of treatment for ≥2 consecutive months — remains a significant barrier. In Western Kenya, default rates at district facilities have been reported at 15–30%, well above the national target of <5%. Factors such as poverty, distance to facility, drug side effects, and stigma have been implicated but are poorly documented at district level.
Problem Statement: Despite free TB treatment provided under the national DLTLD programme, high default rates persist at [Name] District Hospital, compromising treatment outcomes and contributing to drug resistance. The specific factors driving this default have not been studied at this facility.
(b) General Objective: To determine factors associated with TB treatment default among patients at [Name] District Hospital.
Specific Objectives:
  1. To assess socio-demographic characteristics of TB patients who defaulted treatment
  2. To identify patient-related factors (knowledge, side effects, stigma) associated with default
  3. To determine health system factors (distance, drug availability, staff attitude) associated with default
(c) Design: Descriptive cross-sectional study — appropriate for determining prevalence and associated factors at one point in time. Population: All TB patients enrolled in the hospital's TB register in the past 2 years (defaulters and non-defaulters). Sampling: Systematic random sampling from the TB register — every 2nd patient selected until sample size is reached. Sample size: Yamane's formula or Fisher's formula based on estimated 25% default rate, 95% confidence level. Instrument: Interviewer-administered structured questionnaire covering demographics, treatment history, knowledge, side effects, and health system factors. Records review for treatment outcomes.
(d)
  1. Informed consent — patients (defaulters) must be informed of the study purpose and voluntarily agree; no coercion since they fear penalties for default
  2. Confidentiality — TB patient data is sensitive; identifiers must be removed; data stored securely; findings reported in aggregate form

  • Distribution: Who gets it? Where? When? (person, place, time)
  • Determinants: Why? What causes it?
  • Key measures: Incidence, Prevalence, Mortality rate, Morbidity rate

━━━━━━━━━━━━━━━━━━━━━━━━━━━

TOPIC 2: RESEARCH PROBLEM

━━━━━━━━━━━━━━━━━━━━━━━━━━━

Research Gap

An area where knowledge is absent, insufficient, or contradictory — the space between what is known and what needs to be known.
Sources of research gaps:
  • Clinical observation
  • Unanswered questions in published literature
  • Policy or programme needs
  • Community health priorities

Identifying & Prioritising a Research Topic

FINER Criteria — a good research problem must be:
LetterCriterionMeaning
FFeasibleDoable with available time, resources, and skills
IInterestingMotivates the researcher to complete it
NNovelAdds new knowledge; not simply repeating existing work
EEthicalDoes not harm participants; can get ethical approval
RRelevantAddresses a real health need or policy priority

Background of the Study

  • Reviews the global, regional, and local context of the problem
  • Uses statistics and data to show the MAGNITUDE of the problem
  • Leads logically to the problem statement

Problem Statement

A well-written problem statement must contain:
  1. Context — what is the current situation
  2. Magnitude — statistics showing extent of the problem
  3. The gap — what is NOT yet known locally
  4. Consequences — what happens if unaddressed
  5. Proposed investigation — what the study will explore
✏️ Example: "Despite free TB treatment under the DLTLD programme, default rates at [Name] Hospital remain at 30%, well above the national target of <5%. The specific factors driving this default have not been studied at this facility."

Research Questions

  • Interrogative form of the objective
  • Open-ended questions guiding data collection
  • Example: "What factors contribute to TB treatment default at [Name] Hospital?"

Research Objectives

  • General objective: Broad statement of the overall aim
  • Specific objectives: Narrow, measurable, action-oriented sub-goals
  • Begin with action verbs: assess, determine, compare, establish, evaluate, identify

Hypothesis

TypeDefinitionExample
Null (H₀)States NO difference/effect/association"There is no significant association between smoking and lung cancer"
Alternative (H₁)States there IS a difference/effect/association"There is a significant association between smoking and lung cancer"

TermDefinition
LimitationsWeaknesses beyond the researcher's control (e.g., small sample, self-reporting bias)
AssumptionsConditions accepted as true without testing (e.g., respondents answered honestly)
Scope/DelimitationsBoundaries of the study — what is included and excluded

Conceptual Framework

  • A visual or narrative diagram showing the relationship between variables
  • Shows: Independent variable(s) → Dependent variable(s) and any confounding/intervening variables
  • Guides what to measure and how variables interact

Key Definitions

TermDefinition
Target populationEntire group findings are generalised to
Accessible populationReachable subset of the target population
Sampling frameComplete list from which sample is drawn (e.g., clinic register)
SampleSubset of the population actually studied

Sample Size Determination

  • Yamane's formula (known population): n = N / (1 + N(e²))
    • N = population size, e = margin of error (usually 0.05)
  • Fisher's formula (unknown/large population): n = Z²pq / d²
    • Z = 1.96 (95% confidence), p = expected proportion, q = 1-p, d = 0.05

Sampling Techniques

Probability (Random) Sampling

MethodHow it works
Simple randomEvery member has equal chance; lottery or random numbers
Stratified randomDivide into strata → randomly sample each stratum
SystematicSelect every nth person from an ordered list
ClusterRandomly select groups (clusters); study all within cluster

Non-Probability Sampling

MethodHow it works
PurposiveDeliberately select based on specific characteristics
ConvenienceSelect whoever is readily available
SnowballExisting participants recruit others (used in hard-to-reach populations)

C. Data Collection

Types of Data

  • Primary data: Collected fresh by the researcher (questionnaires, interviews, observation)
  • Secondary data: Already existing (hospital records, MOH reports, registers)

Data Collection Instruments

InstrumentBest Used For
Structured questionnaireLarge samples; literate populations; quantitative data
Interview guideQualitative data; illiterate/semi-literate populations
Observation checklistBehaviours, practices, clinical procedures
Document review guideSecondary data from records/files

E. Validity and Reliability

Validity — "Are we measuring the right thing?"

TypeDefinition
Content validityItems cover all aspects of the concept (expert review)
Criterion validityResults correlate with a gold standard measure
Construct validityInstrument measures the theoretical construct
Face validityInstrument appears relevant to experts/respondents

Reliability — "Do we get consistent results?"

TypeDefinition
Test-retestSame instrument, same group, different times → similar results
Inter-raterDifferent observers using same instrument → similar results
Internal consistencyItems measuring the same concept give similar scores (Cronbach's alpha ≥ 0.7)
Key rule: An instrument can be reliable WITHOUT being valid, but a valid instrument MUST also be reliable.

TOPIC 5: RESEARCH ETHICS

━━━━━━━━━━━━━━━━━━━━━━━━━━━

History of Research Ethics

EventYearSignificance
Nuremberg Code1947First international code after Nazi experiments; established voluntary consent
Declaration of Helsinki1964WMA guidelines for medical research involving humans; updated regularly
Belmont Report1979Three core principles: Respect, Beneficence, Justice
KEMRI/NACOSTIOngoingKenya's national ethical oversight framework

Belmont Report — Three Core Principles

1. Respect for Persons (Autonomy)

  • Individuals are autonomous agents — they decide for themselves
  • Informed consent must be obtained
  • Vulnerable groups (children, prisoners, mentally ill) need extra protection

2. Beneficence

  • Maximise benefits to participants and society
  • Minimise harm and risk
  • Benefits must clearly outweigh risks

3. Justice

  • Fair selection of participants — no group exploited for another's benefit
  • Risks and benefits distributed equitably across society

Explain made easy

SIRS → Sepsis → MODS → Death

Your Body Can Kill Itself — Made Easy


THE BIG IDEA 🧠

Imagine your body's defense system is like a fire alarm. A small fire (infection/injury) triggers the alarm. But sometimes the alarm goes so crazy it burns down the whole house trying to put out the fire. That is SIRS → Sepsis → MODS.

STEP 1: SIRS

Systemic Inflammatory Response Syndrome

What is it?

Your body detects a threat (infection, burn, trauma, surgery) and launches a massive inflammatory response — like calling ALL your soldiers to war at once.

Think of it as:

🔥 "The body overreacts to a problem"

Diagnosis — ANY 2 of these 4 criteria:

CriteriaAbnormal Value
Temperature>38°C (fever) OR <36°C (hypothermia)
Heart Rate>90 beats/minute (tachycardia)
Respiratory Rate>20 breaths/min OR PaCO₂ <32 mmHg
White Blood Cells>12,000 OR <4,000 cells/mm³ OR >10% bands

Key point:

  • SIRS can happen WITHOUT infection — burns, pancreatitis, major trauma all cause SIRS
  • It is the body's inflammatory fire alarm gone loud

STEP 2: SEPSIS

When SIRS + Infection = Sepsis

What is it?

When that same overreaction (SIRS) is triggered by a confirmed or suspected INFECTION.

Simple formula:

🦠 SIRS + Infection = SEPSIS

Think of it as:

"Your immune system is fighting an infection but it's fighting TOO hard — and now it's damaging your own organs in the process."

What happens inside the body:

  1. Bacteria/virus enters the blood
  2. Immune system releases cytokines (chemical alarm signals) — TNF, IL-1, IL-6
  3. These cytokines cause widespread inflammation throughout the body
  4. Blood vessels dilate (widen) → blood pressure drops
  5. Blood clots abnormally in small vessels → blocks organ blood flow
  6. Organs begin to receive less oxygen

Signs of Sepsis (qSOFA — quick bedside tool):

  • Altered mental status (confusion)
  • Respiratory rate ≥ 22/min
  • Systolic BP ≤ 100 mmHg
Score 2 or more = likely sepsis

STEP 3: SEVERE SEPSIS & SEPTIC SHOCK

Severe Sepsis:

Sepsis + Organ dysfunction The fire is now burning the organs

Septic Shock:

Severe sepsis + Persistent hypotension despite giving IV fluids
  • Systolic BP < 90 mmHg even after fluid resuscitation
  • Body needs vasopressors (drugs to squeeze blood vessels) just to maintain pressure

Think of it as:

🚨 "Blood pressure has collapsed. The organs are in danger. This is a medical emergency."

STEP 4: MODS

Multiple Organ Dysfunction Syndrome

What is it?

The inflammatory storm has now damaged multiple organs at the same time.

Think of it as:

💥 "The fire has spread to every room in the house."

Organs that fail — one by one (or all at once):

OrganWhat HappensSigns You See
LungsARDS (fluid fills air sacs)Low O₂, needs ventilator
KidneysAcute Kidney Injury↑ Creatinine, low urine output
LiverHepatic dysfunction↑ Bilirubin, jaundice
HeartMyocardial depressionLow BP, arrhythmias
BrainEncephalopathyConfusion, coma
BloodDIC (clotting everywhere)Bleeding + clotting simultaneously
GI tractGut ischaemiaIleus, GI bleeding

Key rule:

The more organs that fail, the higher the mortality.
  • 1 organ failing → ~15–20% death
  • 2 organs → ~40–50%
  • 3+ organs → >80% death

THE FULL CASCADE — SIMPLIFIED

    Body overreacts
           ↓
         SIRS
  (inflammation everywhere)
           ↓
    + Confirmed Infection

           ↓
    Organs not getting blood
           ↓
     SEVERE SEPSIS
   (first organ starts failing)
           ↓
   BP crashes despite fluids
           ↓
     SEPTIC SHOCK
           ↓
  Multiple organs now failing
           ↓
         MODS
           ↓
    ⚠️ DEATH (if untreated)

WHY DOES THE BODY KILL ITSELF?

Normal response vs. SIRS/Sepsis response:

NormalSIRS/Sepsis
InflammationLocal, controlled, resolvesSystemic, uncontrolled, escalating
CytokinesHelp fight infection locallyFlood the whole bloodstream
Blood vesselsNormal toneAll dilate → BP crashes
ClottingNormalMicro-clots block tiny blood vessels
OrgansFunction normallyStarved of oxygen → fail

The paradox:

The body's own defense mechanism — inflammation — becomes so exaggerated that it destroys healthy tissue, collapses blood pressure, and shuts down organs. The cure becomes the killer.

MANAGEMENT SUMMARY

The Sepsis 1-Hour Bundle (Surviving Sepsis Campaign)

StepAction
1Measure lactate (>2 mmol/L = concern; >4 = organ hypoperfusion)
2Take blood cultures × 2 BEFORE giving antibiotics
3Give broad-spectrum IV antibiotics immediately
4Give 30 ml/kg IV crystalloid (Normal Saline or Ringer's Lactate) for hypotension
5Give vasopressors (Noradrenaline first choice) if BP stays low after fluids

Remember: TIME = ORGANS

Every hour of delay in antibiotics increases mortality by ~7%

MEMORY TRICKS 🧠

SIRS criteria → "The Hot Tachycardic Breathless WBC"
Temp + Heart Rate + Respiratory Rate + WBC
SIRS → Sepsis → Shock → MODS progression:
"Soldiers Start Shooting Madly" S = SIRS, S = Sepsis, S = Shock, M = MODS
Septic Shock vs Severe Sepsis:
Severe Sepsis = organ dysfunction Septic Shock = organ dysfunction + BP won't come up with fluids
MODS organs failing:
"Lungs, Kidneys, Liver, Heart, Brain, Blood, Gut" "Lucky Kidneys Let Heart Beat Bright Green"

QUICK SUMMARY TABLE

StageDefinitionKey Feature
SIRSSystemic inflammatory response to any insult≥2 of 4 criteria; no infection needed
SepsisSIRS + confirmed/suspected infectionOrgan dysfunction begins
Severe SepsisSepsis + organ dysfunctionAt least one organ failing
Septic ShockSevere sepsis + persistent hypotension despite fluidsNeeds vasopressors
MODSMultiple organ failure≥2 organs failing; high mortality

Bottom line: Your body's immune system is designed to protect you. But when it loses control — whether from infection, trauma, or burns — it attacks everything, including your own organs. The key to saving patients is recognising the cascade early and breaking it with fluids, antibiotics, and organ support before MODS sets in.
