Concept Note Review: Optimising AMS Surveillance Through Medication Data Standardisation in Zambia


PART 1 - WEAKNESSES IN THE CONCEPT NOTE

1. Incomplete and Unresolved Internal Actions

The document contains multiple open [ACTION REQUIRED] flags that have not been resolved before submission - including a pending nomination for the Community Engagement and Involvement (CEI) Lead, an unconfirmed ZNPHI data format, and an unresolved clarification about which facilities the prior PPS rounds covered. These are not minor editorial issues; they represent gaps in the study's scientific and logistical foundation. A reviewer reading this draft would see an unfinished proposal, not a polished concept note.

2. Thin Justification for OMOP CDM in a Resource-Constrained Setting

The integration of the OMOP Common Data Model is described as a "distinguishing feature," but the concept note does not adequately address the infrastructural barriers to OMOP adoption in Zambia's public hospitals. Most of the nine target facilities currently use paper ledgers or DHIS2 - systems with very different data architectures. The note does not explain what minimum IT infrastructure is required, whether existing hospital systems can be migrated, or who will maintain the OMOP instance after the grant ends. The sustainability of the most technically ambitious component is therefore not demonstrated.

3. Over-reliance on a Single External Technical Contractor

The OMOP CDM implementation is contracted to one external consultant (Adam Bouras, Morocco) via a yet-to-be-signed MOU. This creates a single point of failure: if the contractor is unavailable, the core technical objective stalls. There is no description of internal capacity-building or technology transfer to Zambian staff, which is inconsistent with NIHR's equitable partnership principles and risks the long-term sustainability of the technical platform.

4. Weak Exit Strategy and Sustainability Plan

Beyond vague references to open-access outputs and OHDSI submission, there is no concrete plan for sustaining the toolkit after the 36-month project period. Who will update the RxNorm crosswalk as the Zambia Essential Medicines List changes? Who owns and maintains the DHIS2 plugin? How will new facilities be onboarded? The note does not address how the Ministry of Health or ZNPHI will be formally handed ownership of the outputs.

5. Methodology Lacks a Theory of Change

The three-phase design is described in operational terms (audit, co-design, deployment) but there is no explicit theory of change connecting the activities to the intended outcomes. It is not clear, for example, how improved data standardisation will translate into changes in prescribing behaviour or AMR outcomes. The success metrics listed (error rate reduction, AWaRe coverage) are process metrics, not outcome metrics. A reviewer would want to see a logical framework or results chain.

6. Community and Patient Perspectives Absent from the Research Design

Section 4 (CEI) has a placeholder for a nominated lead but no substantive plan. Patients - especially those from vulnerable groups mentioned in Section 5 - are described as beneficiaries but are not meaningfully involved in toolkit co-design, data governance decisions, or dissemination planning. This is a significant gap for a NIHR-funded proposal, where public and patient involvement is a scored criterion.

7. Ethical Considerations Are Underdeveloped

The concept note does not mention data governance, patient confidentiality, or consent frameworks for the use of retrospective PPS datasets. Given that the data will be uploaded to an OMOP instance potentially accessible by the OHDSI federated network, the absence of any discussion of data sharing agreements, de-identification protocols, or national data sovereignty is a notable omission.

8. Sex-Disaggregated Analysis Lacks Depth

Section 5 notes that sex and gender will be considered, but the proposed analyses remain at the level of stratified description. There is no discussion of whether the statistical power is adequate to detect sex-differentiated prescribing patterns, nor how gender-qualitative insights will be obtained from patients in a data standardisation study that is largely technical in focus.

9. Partnership Imbalance Towards International Partners

Oxford NDORMS and Duke-NUS hold prominent named co-investigator roles, while the Zambian co-investigators (beyond Dr. Chanda) are listed as in-country coordinators or consultants. This could be read as a traditional North-South structure rather than the genuine LMIC-led model that NIHR's Global Health Research Band 3 funding stream prioritises. The note should more explicitly articulate who makes which decisions, who holds the intellectual property, and how Zambian early-career researchers are being developed.

10. Unclear Baseline: How Many Facilities Have Existing DHIS2?

The concept note refers to "DHIS2/HMIS" systems as the electronic infrastructure but does not map which of the nine facilities actually have functional DHIS2 installations. Without this baseline information, the feasibility of the interoperability objective cannot be assessed.

PART 3 - PLAIN ENGLISH SUMMARY (2,980 words)

What is this project about?
Antibiotics are medicines that kill or stop the growth of bacteria. When they are used too much, used wrongly, or when patients do not finish their treatment, bacteria learn to fight back against the medicine. This is called antimicrobial resistance (AMR). It is one of the biggest health threats in the world today. Scientists estimate that if nothing changes, AMR could cause tens of millions of deaths globally over the next 25 years, with the worst effects in poorer countries, including those in Africa.
Zambia is already dealing with this problem. At hospitals across the country, a very high proportion of patients admitted to wards are being treated with antibiotics - in some surveys, as many as 70 to 81 out of every 100 inpatients were receiving at least one antibiotic. Many of these antibiotics belong to a group called "Watch" antibiotics - stronger medicines that should be used carefully and only when Access-group antibiotics have not worked. Using Watch antibiotics too frequently and too freely is a sign that antibiotic use is not being managed as carefully as it should be.
Zambia has been working hard to improve this situation. The country launched a National Action Plan on AMR in 2017. A team of doctors, pharmacists, and researchers - based mainly at the University Teaching Hospital (UTH) in Lusaka and supported by an international organisation called ICARS - ran a three-year programme from 2020 to 2023 to improve how antibiotics are used in hospitals. This programme covered three large teaching hospitals and six smaller hospitals across Zambia. The teams did regular surveys, called Point Prevalence Surveys (PPS), where they walked through wards and recorded which patients were on which antibiotics on a given day. They used this information to train prescribers, improve hospital guidelines, and set up Antimicrobial Stewardship (AMS) committees - groups of healthcare workers whose job is to make sure antibiotics are used wisely.
The surveys showed early signs of progress. In the three main hospitals, the proportion of patients on antibiotics dropped from 81% in 2022 to 71% in 2023. The use of ceftriaxone, the most prescribed antibiotic, fell from 48% to 38%. Adherence to treatment guidelines improved slightly, from 42% to 45%. These are encouraging changes, but there is still a long way to go.
What is the problem this new project is trying to solve?
When the research team analysed the data they had collected across the nine hospitals, they ran into a serious problem that had nothing to do with clinical care - it was a data problem. Each hospital had been recording the names of antibiotics differently. Some used brand names (the names drug companies give their products). Others used generic names (the actual chemical names of the medicines). Some records mixed both. Spellings were inconsistent. The same antibiotic might appear as "Amoxil," "amoxicillin," "amoxycillin," or "amoxy" in different hospital records or even in different parts of the same hospital's records. Doses were recorded in different formats. Routes of administration (whether a medicine was given by mouth, injection, or drip) were noted inconsistently or not at all.
This inconsistency makes it almost impossible to compare data between hospitals or to add up totals accurately. It is like trying to measure rainfall across a country when some weather stations record millimetres, some record centimetres, and some just say "a lot" or "a little." The numbers cannot be meaningfully combined or compared.
This matters enormously because the whole point of surveillance is to build a reliable picture of what is happening across the health system. If the data is unreliable, then efforts to improve antibiotic use are based on incomplete or misleading information.
What does this project propose to do?
This project, led by Dr. Duncan Chanda at UTH, aims to fix this data problem. It is funded through the NIHR (the UK's National Institute for Health and Care Research) and will run for three years across the same nine hospitals.
The project has five main objectives:
First, it will map the problem. In the first eight months, the team will do a detailed audit of how antibiotics are currently named and recorded across all nine hospitals. They will look at paper records, computer systems (where they exist), and national-level data held by the Zambia National Public Health Institute (ZNPHI). This will give a clear picture of exactly what is wrong and how bad it is.
Second, it will build a solution. Between months 6 and 18, the team will design a standardisation toolkit. At the heart of this will be a digital "crosswalk dictionary" - essentially a translation tool that can take any of the varied ways an antibiotic is recorded in Zambia and automatically convert it into a standard, internationally recognised code. The standard chosen for drug names is RxNorm, a coding system widely used in health informatics. The drugs will also be tagged with WHO's ATC/DDD classification (which tracks how much of a drug is being used) and the WHO AWaRe categories (Access, Watch, or Reserve), which tell you whether the drug choice is appropriate.
The toolkit will also be designed to work with three key systems: DHIS2 (the national health information platform used across most Zambian hospitals), the Global-PPS platform (the international tool used for antibiotic surveys), and the OMOP Common Data Model (a global framework that allows health data from different countries to be compared and analysed together).
Third, it will test and scale up the toolkit. From months 15 to 36, the team will roll out the toolkit across all nine hospitals using regular quarterly antibiotic surveys. They will measure how well it works by tracking things like: what proportion of antibiotic records can now be successfully mapped to a standard code; how much the rate of naming errors has fallen; and whether AWaRe categories are being captured accurately. Each quarterly cycle will feed back into improving the toolkit.
Fourth, it will build an open-access resource. Once the Zambia-specific drug crosswalk is complete, it will be submitted to OHDSI (the global network that maintains the OMOP system) for inclusion in their publicly available vocabulary database. This means that any other country in the world that has a similar problem with drug name inconsistency will be able to use Zambia's work as a starting point.
Fifth, it will create a model that other countries can copy. The project is explicitly designed so that the methods and tools can be applied by other low- and middle-income countries that face the same challenges with heterogeneous drug naming. The team will produce open-access guides and training materials to enable replication.
Who is involved?
Dr. Duncan Chanda, an infectious disease physician at UTH, leads the project. He was the driving force behind the ICARS three-year AMS programme and has co-authored much of the published evidence on which this project builds. Working alongside him are Dr. Anna Saura-Lazaro (Oxford, UK), who brings experience in pharmacoepidemiology; Dr. Cynthia Sung (Duke-NUS / OHDSI Africa Chapter), who advises on the OMOP CDM integration; and Mr. Rodney Kalaba from the University of Zambia, who coordinates in-country activities. OMOP CDM technical implementation will be contracted to an external consultant, Adam Bouras (Tritonis Inc., Morocco).
The nine hospitals covered are five large teaching hospitals (UTH in Lusaka, Levy Mwanawasa UTH, Kitwe Teaching Hospital, Livingstone UTH, and Ndola Teaching Hospital) plus four smaller first-level hospitals.
Why does this matter beyond Zambia?
The problem this project is trying to solve is not unique to Zambia. Across sub-Saharan Africa and other low- and middle-income regions, health data is fragmented, drug names are inconsistent, and the tools needed to track antibiotic use accurately have not been adapted for local contexts. Currently, most drug coding systems - including RxNorm itself - are built around drug markets in the USA and Europe. Many of the antibiotics available in Zambia, including local brand variants, are simply not in the standard databases. This project will fill that gap by building the first comprehensive Zambia-specific drug vocabulary for AMR surveillance, and by contributing it back to the global system.
The project also positions Zambia to participate in federated, cross-country health research through the OHDSI network. Federated research means that data stays in the country (it never leaves Zambian servers) but can be analysed in coordinated studies alongside data from other countries. This is a major step towards giving Zambian researchers and policymakers access to global-scale evidence on antibiotic resistance patterns.
What are the expected outcomes?
By the end of the project, the team expects to have: a validated antibiotic standardisation toolkit deployed and actively used across all nine hospitals; a Zambia-specific RxNorm crosswalk covering the national essential medicines formulary; quarterly PPS data that is consistent, comparable, and interoperable across facilities; a measurable reduction in drug naming errors; more accurate tracking of Watch- and Reserve-group antibiotic use; and a set of open-access tools and training materials that other countries can adapt and use.
In practical terms, health authorities in Zambia will be better placed to know which antibiotics are being over-used, which facilities have the worst prescribing practices, and whether stewardship interventions are actually working. That information is the foundation for evidence-based policy decisions about antibiotic use - and ultimately for protecting the medicines that Zambian patients depend on.

PART 4 - HOW TO INCORPORATE COMMUNITY ENGAGEMENT

The concept note currently has a placeholder for a CEI Lead but no substantive community engagement plan. Below are concrete, practical ways to embed community engagement across the three phases without significantly increasing costs or complexity.

Phase 1 (Months 1-8): Scoping and Baseline Audit

Patient advisory panels at participating hospitals. Each of the nine facilities should have a small advisory group of 5-8 patients or community members who are asked a simple question: "Do you know what antibiotics you were given, and why?" Their answers will tell the research team whether current practices are meeting patients' right to information - and whether the data collection gaps have real-world consequences for patients. This can be done as structured conversations during regular outpatient or ward rounds.
Community health worker (CHW) mapping. Zambia has an established network of community health workers who operate between health facilities and households. CHWs can be involved in Phase 1 mapping exercises to document how community members, traditional healers, and informal medicine sellers refer to antibiotics. This will populate the crosswalk dictionary with community-level drug name variants that would not appear in hospital records alone (e.g., local trade names purchased from pharmacies or markets).

Phase 2 (Months 6-18): Toolkit Co-Design

Plain language lay summaries co-produced with patients. Patients admitted to wards during PPS cycles should be given a one-page, plain-language explanation of what the survey is, why their data is being collected, and how it will be used. This summary should be co-designed with members of the patient advisory panel from Phase 1, and translated into local languages (Nyanja, Bemba, Tonga) where relevant.
Community representative on the Steering Committee. The project's governance structure (currently described only in terms of academic and clinical stakeholders) should include at least one community representative. This could be a patient advocate, a healthcare consumer organisation, or a community health worker supervisor. Their role is to ensure that the toolkit design and the data governance framework reflect the priorities and concerns of the communities being served.
Gender-specific focus groups. Section 5 of the concept note notes sex-differentiated antibiotic exposure (e.g., women via obstetric care, men via zoonotic pathways). Rather than relying solely on quantitative data disaggregation, short focus group discussions with women attending antenatal clinics at the maternal and neonatal wards (priority audit sites per the concept note) would provide qualitative context about antibiotic experiences, concerns, and information needs that cannot be captured in a PPS data field.

Phase 3 (Months 15-36): Implementation and Scale-Up

Feedback loops to communities. When quarterly PPS results are available, brief summaries (not just academic reports) should be shared with hospital communities - meaning patients, families, and local community leaders - through facility notice boards, radio announcements, or community health worker networks. This is not just about transparency; evidence from other LMIC settings shows that community awareness of AMS drives demand for appropriate antibiotic use and reduces pressure on prescribers to give unnecessary antibiotics.
Community AMR awareness integrated with toolkit rollout. Each quarterly PPS cycle is an opportunity to run a brief community awareness session at the participating facility. These do not need to be elaborate; a 30-minute session by a pharmacist or AMS committee member, timed with clinic waiting times, explaining what antibiotics are, why finishing a full course matters, and when antibiotics cannot help (e.g., viral infections), directly supports the stewardship objectives of the project.
Documenting community engagement as a study output. The community engagement activities should be formally documented and evaluated as part of the Phase 3 outcomes. A short process evaluation asking community members and CHWs whether they feel informed and involved will generate evidence that is publishable and replicable - adding to the body of knowledge on participatory AMR research in LMICs, where this literature is currently very thin.

Practical Governance Recommendations

  • Name the CEI Lead (as required by the open action item in the concept note) and budget for their time. A pharmacist or nurse already on one of the nine AMS committees is the most practical choice.
  • Include a line item in the budget for translation of patient-facing materials, CHW engagement sessions, and community feedback activities.
  • Reference NIHR's own Going the Extra Mile framework for public involvement to signal alignment with funder expectations.
  • Link the CEI plan to the inclusive research section (Section 5) to show coherence: the sex/gender analysis and the community engagement plan should be part of one integrated equity strategy, not two separate boxes to be ticked.

Implementation of the NAP, and the national Standard Treatment Guidelines (STG) and National Formulary (NF) — which prescribe antimicrobials according to the WHO Access, Watch and Reserve (AWaRe) classification and align with the RxNorm vocabulary standard — has driven the establishment of Antimicrobial Stewardship (AMS) structures across public health facilities. These include Medicines and Therapeutics Committees (MTCs) and the Ministry of Health-recognised policy committee for the Promotion of Rational Medicine Use.'),

Six additional first-level hospitals across three provinces were also engaged as satellite sites. Three rounds of Point Prevalence Surveys (PPS) were conducted across the three tertiary facilities during this period, generating a unique longitudinal dataset on in-hospital antibiotic use [2, 3]. This programme demonstrated early but measurable stewardship impact: antibiotic prescribing prevalence fell from 81% to 71% between 2022 and 2023; ceftriaxone prescribing declined from 48% to 38%; and Standard Treatment Guideline adherence improved from 42% to 45% [2].')]),

PPS datasets generated across the nine project hospitals reflect inconsistent drug naming conventions (mixing generic names, brand names, and free-text descriptions), varied metric indicators (ATC codes, RxNorm, or unmapped free text), and misaligned denominator reporting. This fragmentation prevents meaningful cross-facility comparison, undermines the ability to track AWaRe antibiotic utilisation trends, and limits the translation of PPS evidence into national AMR policy [4, 5]. A national cross-sectional survey found that more than 64% of healthcare professionals reported limited access to essential AMR data and inadequate IT infrastructure [4], and that no hospital surveyed had an allocated AMS budget [5].'),

The project is further strengthened by its integration with the OHDSI Africa Chapter Medication Standardisation Working Group. By mapping the resulting standardised antibiotic nomenclature to the OMOP Common Data Model (CDM) drug exposure vocabulary, Zambia\'s PPS data will become interoperable with a global federated research network spanning over 100 countries — enabling cross-country AMR pharmacoepidemiology and drug utilisation research at continental and global scale [6, 7].')]),

Version3.0 — July 2026 (Revised)

1. Background and Rationale

Antimicrobial resistance (AMR) represents one of the most urgent threats to global health security. Left unaddressed, AMR risks returning the world to a pre-antibiotic era in which common infectious diseases become untreatable and routine surgical procedures carry unacceptable mortality risk. Globally, AMR is estimated to cause 39 million deaths between 2025 and 2050, with the highest mortality burden concentrated in low- and middle-income countries (LMICs) [1].
Zambia launched its National Action Plan (NAP) on AMR in 2017, structured around five pillars: (i) awareness and understanding; (ii) surveillance and research; (iii) infection prevention; (iv) optimising antimicrobial use; and (v) sustainable investment. Implementation of the NAP, and the national Standard Treatment Guidelines (STG) and National Formulary (NF) — which prescribe antimicrobials according to the WHO Access, Watch and Reserve (AWaRe) classification and align with the RxNorm vocabulary standard — has driven the establishment of Antimicrobial Stewardship (AMS) structures across public health facilities. [Improvement: explicit reference to the STG/NF alignment with AWaRe and RxNorm incorporated per reviewer comment, as was absent from the prior draft] These structures include Medicines and Therapeutics Committees (MTCs) and the Ministry of Health-recognised policy committee for the Promotion of Rational Medicine Use. [Improvement: MTCs and the MOH policy committee named explicitly, as recommended by co-author review]
Between 2020 and 2023, UTH — through a grant from the International Centre for Antimicrobial Solutions (ICARS) — implemented a three-year AMS demonstration programme across three tertiary hospitals: UTH Lusaka, Livingstone UTH, and Ndola Teaching Hospital. Six additional first-level hospitals across three provinces were also engaged as satellite sites. Three rounds of Point Prevalence Surveys (PPS) were conducted across the three tertiary facilities during this period, generating a unique longitudinal dataset on in-hospital antibiotic use [2, 3]. [Improvement: factual ambiguity about which facilities ran the PPS rounds resolved — the three rounds were conducted in the three tertiary facilities only; scale-up to all nine is the objective of this project] This programme demonstrated early but measurable stewardship impact: antibiotic prescribing prevalence fell from 81% to 71% between 2022 and 2023, ceftriaxone prescribing declined from 48% to 38%, and Standard Treatment Guideline adherence improved from 42% to 45% [2].
Despite this progress, a critical barrier persists: the absence of standardised antibiotic nomenclature and data collection frameworks across facilities. PPS datasets generated across the nine project hospitals reflect inconsistent drug naming conventions (mixing generic names, brand names, and free-text descriptions), varied metric indicators (ATC codes, RxNorm, or unmapped free text), and misaligned denominator reporting. This fragmentation prevents meaningful cross-facility comparison, undermines the ability to track AWaRe antibiotic utilisation trends, and limits the translation of PPS evidence into national AMR policy [4, 5]. A national cross-sectional survey confirmed that over 64% of healthcare professionals reported limited access to essential AMR data and inadequate IT infrastructure [4], and no hospital surveyed had an allocated AMS budget [5].
This project addresses these gaps directly by improving and harmonising existing AMS surveillance infrastructure across Zambia. It does not seek to establish new surveillance systems. Rather, it builds on the established ICARS cohort, existing AMS committees, and existing PPS cycles to engineer, validate, and deploy an interoperable, open-access medication standardisation toolkit — aligned with the WHO PPS framework, the AWaRe classification, and the RxNorm vocabulary standard. The project is further strengthened by its integration with the OHDSI Africa Chapter Medication Standardisation Working Group. By mapping the resulting standardised antibiotic nomenclature to the OMOP Common Data Model (CDM) drug exposure vocabulary, Zambia's PPS data will become interoperable with a global federated research network spanning over 100 countries — enabling cross-country AMR pharmacoepidemiology and drug utilisation research at continental and global scale [6, 7].

2. Aims and Objectives

GOAL: To optimise the uniformity, structural reliability and comparability of hospital-based point prevalence surveys in Zambia through a rigorous, scalable medication standardisation framework — improving existing AMS surveillance infrastructure and enabling evidence-based national AMR policy.

Specific Objectives

  • Objective 1: To conduct a comprehensive baseline audit of structural data variations, antibiotic naming conventions, dose reporting systems, and metric indicators across nine health facilities in four districts of Zambia, incorporating national antibiotic consumption data from ZNPHI.
  • Objective 2: To co-design a digital medication standardisation toolkit with frontline prescribers, pharmacists, AMS committee members, and community representatives, leveraging existing ICARS PPS data and national surveillance data from ZNPHI. [Improvement: community representatives added to co-design team to address the absence of patient and community voice in the original objective]
  • Objective 3: To develop a standardised antibiotic nomenclature framework using RxNorm as the primary coding standard, with parallel mapping to WHO ATC/DDD classifications and AWaRe categories, and interoperability with the OMOP Common Data Model.
  • Objective 4: To validate and deploy the standardisation toolkit across all nine facilities through quarterly PPS cycles, measuring reduction in nomenclature reporting errors and improvement in AWaRe utilisation metrics.
  • Objective 5: To establish a replicable, open-access standardisation model applicable to other LMIC settings with heterogeneous pharmaceutical landscapes, with all toolkit outputs and the Zambia-specific RxNorm crosswalk submitted to OHDSI ATHENA for global access.

3. Methodology and Study Design

The study employs a mixed-methods, multi-centre operational research design, implemented in three sequential phases across nine health facilities in four districts of Zambia. The nine facilities span tertiary, first-level, and urban primary care settings, ensuring the toolkit is developed for the full heterogeneity of Zambian healthcare delivery.

Phase 1: Baseline Structural Audit (Months 1–8)

A systematic audit of data fragmentation across all nine facilities, encompassing: documentation variations in paper ledgers and electronic health records (DHIS2/HMIS); raw antibiotic nomenclature taxonomy; dose and frequency recording practices; and route of administration conventions. [Improvement: the audit will additionally map which of the nine facilities have functional DHIS2 installations and define the minimum IT infrastructure requirements for toolkit deployment — this feasibility mapping was absent from the prior draft and is essential to demonstrate that the interoperability objective is achievable] The audit will also incorporate national-level antibiotic consumption data from ZNPHI — specifically aggregated facility consumption reports and GLASS-methodology surveillance data [8] — providing a population-level denominator to contextualise facility-based PPS findings.

Phase 2: Toolkit Co-Design (Months 6–18)

Building on the ICARS three-year AMS cohort data and Phase 1 audit findings, this phase will: (i) construct a localised digital cross-walking dictionary that automatically translates heterogeneous text inputs — including localised brand variants, misspelled generic names, and trade name variations — into standardised molecules mapped to their canonical RxNorm codes, WHO ATC/DDD classifications, and AWaRe categories [9]; (ii) format an open-access platform compatible with DHIS2, the Global-PPS platform, and the OMOP Common Data Model; and (iii) develop a Zambia-specific RxNorm crosswalk for the national essential medicines formulary. Co-design workshops will include frontline prescribers, pharmacists, AMS committee members, community health workers, and patient advisory panel members from all nine facilities. [Improvement: community health workers and patient advisory panel members explicitly incorporated into co-design]

Phase 3: Implementation, Validation, and Scale-Up (Months 15–36)

Sequential deployment of the toolkit across all nine facilities using standardised quarterly PPS cycles. Evaluation metrics will include: proportion of antibiotics successfully mapped to RxNorm/ATC codes; reduction in nomenclature error rates; proportion of AWaRe categories accurately captured; and guideline adherence rates. Findings from each cycle will inform iterative toolkit refinement. [Improvement: structured technology transfer sessions will be conducted quarterly throughout Phase 3 to build the capacity of UTH pharmacoinformatics and data management staff to operate and update the standardisation toolkit and crosswalk independently after grant completion — this was absent from the prior draft and directly addresses the sustainability gap]

Target Settings

  • Tertiary (5): University Teaching Hospital (UTH), Levy Mwanawasa UTH, Kitwe Teaching Hospital, Livingstone UTH, Ndola Teaching Hospital
  • First-level hospitals (4): to be confirmed and named prior to grant submission

4. Community Engagement and Involvement (CEI)

[Improvement: this section was a placeholder in Version 2.0. It has been replaced with a substantive CEI plan to meet NIHR's scored public and patient involvement criterion.]
Community and patient engagement is embedded across all three project phases, consistent with NIHR's Going the Extra Mile framework for public involvement in research. The CEI Lead will be a pharmacist or AMS committee member drawn from one of the nine participating facilities, nominated by Dr. Chanda prior to grant commencement, and budgeted accordingly.
Phase 1 engagement: Patient advisory panels (5–8 members per facility) will be convened at each of the nine hospitals to document patients' experiences of antibiotic prescribing — including whether they know which medicines they received and why. Community health workers (CHWs) will participate in the drug naming audit to capture community-level antibiotic name variants, including local trade names and products available from pharmacies or informal markets, which would not appear in hospital records alone.
Phase 2 engagement: All patients involved in PPS cycles will receive a one-page, plain-language information sheet co-produced with patient advisory panel members and translated into Nyanja, Bemba, and Tonga. A community representative will sit on the project Steering Committee to provide oversight of data governance and toolkit design decisions. Gender-specific focus groups with women attending antenatal clinics at the priority maternal and neonatal ward audit sites will provide qualitative context on antibiotic exposure that cannot be captured in PPS data fields alone.
Phase 3 engagement: Quarterly community feedback summaries — distinct from academic reports, written in accessible language — will be disseminated through facility notice boards and CHW networks. Short AMR awareness sessions (approximately 30 minutes, co-facilitated by pharmacists and CHWs) will be conducted alongside each quarterly PPS cycle during clinic waiting periods. The reach and quality of all CEI activities will be formally evaluated and reported as a project output, contributing to the limited published evidence on participatory AMR research methods in LMICs.

5. Inclusive Research: Sex, Gender and Vulnerable Populations

Sex and gender will be considered throughout the full research lifecycle. Evidence from LMICs indicates that antibiotic prescribing patterns, AMR exposure pathways, and access to effective treatment differ by sex and gender [10]. Women of reproductive age face disproportionate antibiotic exposure through obstetric and gynaecological care; men in manual occupations face higher zoonotic AMR exposure. These differences will be captured in the Phase 1 baseline audit by disaggregating PPS data by sex where available. Gender-specific focus groups (detailed in Section 4) will supplement quantitative disaggregation with qualitative insight from women in priority wards. [Improvement: CEI gender focus groups cross-referenced here to show the sex/gender analysis and community engagement strategy are integrated, not separate]
Maternal and neonatal wards within the five tertiary facilities are designated as priority audit sites, in recognition of NIHR's particular interest in AMR outcomes for pregnant women and newborns. The toolkit will be designed to accommodate the antibiotic regimens specific to these wards, including prophylaxis protocols, which are currently among the least standardised in Zambian hospital records.
Gender equity will be applied to the research team itself: mentorship posts, named co-investigator roles, and postgraduate training opportunities will be advertised in open competition with explicit encouragement of female candidates from non-academic hospital sites. [Improvement: Zambian early-career researchers will be supported through named co-investigator roles and guaranteed lead authorship opportunities on all primary publications — this directly addresses the partnership balance concern and aligns with NIHR's LMIC-led research principles]

6. OMOP CDM Integration and Technical Arrangements

A distinguishing feature of this project is its integration with the OMOP Common Data Model (CDM), the global standard for observational health data developed and maintained by OHDSI [6]. The OMOP CDM drug exposure table requires standardised medication coding — specifically RxNorm, SNOMED-CT, or INN — to enable federated analysis across participating institutions worldwide.
Subject to grant award, UTH will enter into a Memorandum of Understanding (MOU) with Adam Bouras (Tritonis Inc., Morocco) for the technical implementation of an OMOP CDM instance at UTH. Adam Bouras brings extensive OMOP CDM implementation experience (OHDSI since 2016; CDC Atlanta Data Modernisation Initiative) and co-leads the OHDSI Africa Chapter Medication Standardisation Working Group in a voluntary capacity. His role in this grant is strictly as an external technical contractor; he does not hold a formal position within any African institution and is not named as a co-applicant on the NIHR application. [Improvement: the MOU will explicitly require a structured technology transfer programme under which UTH staff are trained and certified to operate the OMOP instance independently — preventing the project's most technically ambitious component from being contingent on a single external individual after grant end]
The RxNorm crosswalk developed in Phase 2 will be submitted through the OHDSI Africa Chapter to the OHDSI vocabulary team for integration into ATHENA — making Zambia's standardised antibiotic nomenclature globally searchable and interoperable [6, 7]. This positions Zambia as a pioneer in AMR pharmacoepidemiology within the OHDSI federated network, enabling cross-country drug utilisation studies that would otherwise be impossible with siloed national datasets.

7. Equitable and Sustainable Partnerships

University Teaching Hospital (UTH) — Lead Institution: UTH is the contracting institution and primary decision-making authority. Dr. Chanda, as Lead Applicant, holds intellectual property and publication rights. All final publications will list Zambian researchers in lead authorship positions. UTH's Department of Internal Medicine and Infectious Diseases will host the postgraduate training and mentorship programme [2, 3].
Oxford NDORMS — Supporting Partner: Dr. Saura-Lázaro provides pharmacoepidemiology expertise and methodological oversight for the OMOP CDM integration. Oxford's role is advisory and technical support; all primary data collection, analysis, and policy engagement is led from Zambia.
Duke-NUS / OHDSI Africa Chapter — Strategic Partner: Dr. Cynthia Sung advises on OHDSI network integration and co-leads the Africa Chapter Medication Standardisation Working Group, ensuring the Zambia RxNorm crosswalk is developed in alignment with broader regional standardisation efforts [6, 7].
[Improvement: explicit three-part sustainability plan added — the prior draft had no concrete exit strategy]
Sustainability Plan: Post-project sustainability is anchored in three mechanisms: (i) the OMOP CDM instance and crosswalk will be owned and maintained by UTH's internal pharmacoinformatics team, trained through the technology transfer programme embedded in Phase 3; (ii) the Zambia EML crosswalk will be registered in OHDSI ATHENA as a permanent open-access vocabulary resource, with update responsibility formally assigned to a ZAMRA working group; and (iii) the quarterly PPS cycle methodology will be formally adopted into the ZNPHI national AMR surveillance calendar, ensuring continuity of standardised surveillance beyond the grant period.

8. Data Governance, Ethics, and Patient Confidentiality

[Improvement: this section is entirely new — the prior draft contained no discussion of ethics, data governance, or patient confidentiality, which is a significant gap for a project proposing to upload hospital data to an internationally connected platform]
Ethical approval will be sought from the University of Zambia Biomedical Research Ethics Committee (UNZABREC) and the Zambia National Health Research Authority (NHRA) prior to commencement of any data collection or retrospective data review. All retrospective PPS datasets will be de-identified at source before transfer to any digital platform. The OMOP CDM instance will be hosted on UTH servers within Zambia; no patient-level data will leave the country without explicit regulatory approval and a formal, signed data sharing agreement.
A project-specific Data Governance Policy will be developed in Phase 1, covering: data ownership (UTH); access controls for the OMOP instance; de-identification standards; conditions under which federated queries may be run through the OHDSI network; and a data breach response protocol. The policy will be reviewed annually by the Steering Committee, including the community representative, and published as an open-access document.

9. Theory of Change

[Improvement: this section is entirely new — the prior draft described activities in operational terms only, with no explicit results chain connecting activities to AMR outcomes. A theory of change is a standard requirement for NIHR Band 3 proposals]
The project operates on the following results chain:
  • Inputs: ICARS longitudinal cohort data; established AMS committees across nine facilities; ZNPHI national consumption data; OHDSI technical expertise; community engagement infrastructure; NIHR grant funding.
  • Activities: Baseline structural audit; IT infrastructure mapping; co-design workshops with prescribers, pharmacists, and community representatives; crosswalk dictionary development; toolkit deployment; quarterly PPS cycles; community awareness and CEI sessions; technology transfer training.
  • Outputs: Validated medication standardisation toolkit; Zambia-specific RxNorm crosswalk for the national EML; trained UTH pharmacoinformatics staff; community feedback reports; open-access methodology guide for LMIC replication.
  • Outcomes (within 12 months of project completion): Reduction in antibiotic nomenclature error rates across all nine facilities; accurate AWaRe category capture in at least 80% of PPS records; quarterly PPS data formally integrated into the ZNPHI national AMR surveillance calendar; at least one peer-reviewed publication from the Zambian team.
  • Impact (3–5 years): Improved national AMR policy decisions informed by reliable, standardised, comparable surveillance data; Zambia's antibiotic use data accessible to and comparable within the OHDSI global federated network; standardisation model replicated in at least two other LMIC settings.

A summary of all improvements: Nine changes were made to Version 2.0. Three entirely new sections were added (Data Governance; Theory of Change; and a substantive CEI plan replacing the placeholder). Existing sections were strengthened to resolve the unconfirmed ZNPHI data query, name the MTCs and MOH policy committee, add IT infrastructure feasibility mapping, embed technology transfer into the MOU and Phase 3, add Zambian researcher authorship protections, and introduce a three-part post-grant sustainability plan. Original language was preserved throughout wherever possible.
