Development of a web-based application to improve data collection of antimicrobial utilization in the public health care system in South Africa

Challenges and success stories of the implementation of infection control and antimicrobial stewardship strategies: proceedings of the 5th Global Ministerial Summit on Patient Safety, 2023

The 5th edition of the Global Ministerial Summit on Patient Safety was held in Montreux, Switzerland, in February 2023, delayed by three years due to the COVID-19 pandemic. The overarching theme of the summit was "Less Harm, Better Care - from Resolution to Implementation", focusing on the challenges of implementation of infection prevention and control (IPC) strategies as well as antimicrobial stewardship programs (ASP) around the world. IPC strategies and ASP are of increasing importance due to the substantial burden of healthcare-associated infections and antimicrobial resistance threatening patient safety. Here, we summarize countries' and regional experiences and activities related to the implementation of IPC strategies and ASP shared at the meeting. Full implementation of effective programs remains a major challenge in all settings due to limited support by political and healthcare leaders, and human and financial constraints. In addition, the COVID-19 pandemic challenged already well-established programs. By enforcing sustained implementation by dedicated, cross-disciplinary healthcare personnel with a broad skill set, a reduction in healthcare-associated infections and multidrug-resistant pathogens can be achieved, leading ultimately to improved patient safety.

Antimicrobial stewardship capacity and antibiotic utilisation practices in the Cape Coast Teaching Hospital, Ghana: A point prevalence survey study

INTRODUCTION

Antimicrobial resistance (AMR) is a global threat that necessitates coordinated strategies to improve antibiotic prescribing and reduce AMR. A key activity is ascertaining current prescribing patterns in hospitals to identify targets for quality improvement programmes.

METHODS

The World Health Organisation point prevalence survey methodology was used to assess antibiotic prescribing in the Cape Coast Teaching Hospital. All core variables identified by the methodology were recorded.

RESULTS

A total of 78.8% (82/104) patients were prescribed at least one antibiotic, with the majority from adult surgical wards (52.14%). Significantly longer hospital stays were associated with patients who underwent surgery (p = 0.0423). "Access" antibiotics dominated total prescriptions (63.8%, 132/207) with ceftriaxone, cefuroxime, and ciprofloxacin being the most prescribed "Watch" antibiotics. The most common indications were for medical prophylaxis (59.8%, 49/82) and surgical prophylaxis (46.3%, 38/82). Over one-third of surgical prophylaxis (34.2%, 13/38) indications extended beyond one day. There was moderate documentation of reasons for antibiotic treatment in patient notes (65.9%, 54/82), and targeted therapy after samples were taken for antimicrobial susceptibility testing (41.7%, 10/24). Guideline compliance was low (25%) where available.

CONCLUSIONS

There was high use of antibiotics within the hospital which needs addressing. Identified quality targets include developing surgical prophylaxis guidelines, reviewing "Watch" antibiotic prescribing, and assessing antibiotic durations for patients on two or more antibiotics. Organizational-level deficiencies were also identified that need addressing to help instigate ASPs. These can be addressed by developing local prescribing protocols and antibiotic stewardship policies in this hospital and wider in Ghana and across Africa.

Off-Label and Unlicenced Medicine Use among Hospitalised Children in South Africa: Practice and Policy Implications

BACKGROUND

Information regarding off-label and unlicensed medicine use among South African children is limited. This is a concern as the prescribing of off-label and unlicensed medicines can lead to issues of effectiveness and safety as well as raise liability issues in the event of adverse events. This potentially exposes physicians to legal penalties. Consequently, we sought to determine the prevalence of off-label and unlicensed medicine use among paediatric patients in South Africa to provide future direction.

METHODS

This study retrospectively examined the use of medicine in a point-prevalence survey study (PPS) involving paediatric patients aged (0-2 years) admitted to selected public hospitals in Gauteng Province, South Africa. Data were collected per hospital over two days between February 2022 and July 2022. Demographics, duration of treatment, diagnosis, and medicines prescribed were collected from patient medical records using a mobile application. Prescribed medicines were reviewed against the medicine formularies and other databases to assess their appropriateness.

RESULTS

From three academic hospitals, 184 patient records were reviewed. A total of 592 medicines were dispensed, of which 379 (64.0%) were licensed and 213 (36.0%) were used off-label/unlicensed for paediatric patients 0-2 years of age. The most prevalent off-label and unlicensed medicines were multivitamins (n = 32, 15.0%) and ampicillin injections (n = 15, 7.0%).

CONCLUSION

The frequency of unlicensed and off-label medicine prescribing shown in this study is consistent with the literature and can be considered high. This practice can pose a risk because it adversely affects patients if not properly regulated. Attention is needed to ensure future high-quality, safe, and effective use of medicines.

Antibiotic prescribing to inpatients in Limpopo, South Africa: a multicentre point-prevalence survey

BACKGROUND

Electronic continuous surveillance databases are ideal for monitoring antibiotic use (ABU) in hospitalised patients for antibiotic stewardship programmes (ASP). However, such databases are scarce in low-resource settings. Point prevalence surveys (PPS) are viable alternatives. This report describes ABU and identifies ASP implementation improvement areas in Limpopo Province, South Africa.

METHODS

This cross-sectional descriptive study extracted patient-level ABU data from patients' files using a modified global PPS tool. Data were collected between September and November 2021 at five regional hospitals in Limpopo Province, South Africa. All patients in the wards before 8 a.m. on study days with an antibiotic prescription were included. Antibiotic use was stratified by Anatomic Therapeutic Chemical and Access, Watch, Reserve classifications and presented as frequencies and proportions with 95% confidence intervals (CI). Associations between categorical variables were assessed using the chi-square test. Cramér's V was used to assess the strength of these associations.

RESULTS

Of 804 inpatients surveyed, 261 (32.5%) (95% CI 29.2-35.7) were prescribed 416 antibiotics, 137 were female (52.5%) and 198 adults (75.9%). One hundred and twenty-two (46.7%) patients received one antibiotic, 47.5% (124/261) received two, and 5.7% (15/261) received three or more antibiotics. The intensive care units had a higher ABU (68.6%, 35/51) compared to medical (31.3%, 120/384) and surgical (28.5%, 105/369) wards (p = 0.005, Cramér's V = 0.2). Lower respiratory tract infection (27.4%, 104/379), skin and soft tissue infections (SST) (23.5%, 89/379), and obstetrics and gynaecology prophylaxis (14.0%, 53/379) were the common diagnoses for antibiotic prescriptions. The three most prescribed antibiotic classes were imidazoles (21.9%, 91/416), third-generation cephalosporins (20.7%, 86/416) and combination penicillin (18.5%, 79/416). Access antibiotics accounted for 70.2% (292/416) of prescriptions and Watch antibiotics for 29.6% (123/416) (p = 0.110, Cramér's V = 0.1). Reasons for prescribing and treatment plans were documented in 64.9% (270/416) (95% CI 60.3-69.5) and 21.4% (89/416) (95% CI 17.3-25.3) of prescriptions, respectively.

CONCLUSIONS

The study serves as a baseline for ABU surveillance at the five regional hospitals in Limpopo Province. Lack of documentation indicates poor prescribing practices; ASP should address gaps by deploying evidence-based, multifaceted and stepwise interventions.

Scoping review of health information technology usability methods leveraged in Africa

OBJECTIVE

The aim of this study was to explore the state of health information technology (HIT) usability evaluation in Africa.

MATERIALS AND METHODS

We searched three electronic databases: PubMed, Embase, and Association for Computing Machinery. We categorized the stage of evaluations, the type of interactions assessed, and methods applied using Stead's System Development Life Cycle (SDLC) and Bennett and Shackel's usability models.

RESULTS

Analysis of 73 of 1002 articles that met inclusion criteria reveals that HIT usability evaluations in Africa have increased in recent years and mainly focused on later SDLC stage (stages 4 and 5) evaluations in sub-Saharan Africa. Forty percent of the articles examined system-user-task-environment (type 4) interactions. Most articles used mixed methods to measure usability. Interviews and surveys were often used at each development stage, while other methods, such as quality-adjusted life year analysis, were only found at stage 5. Sixty percent of articles did not include a theoretical model or framework.

DISCUSSION

The use of multistage evaluation and mixed methods approaches to obtain a comprehensive understanding HIT usability is critical to ensure that HIT meets user needs.

CONCLUSIONS

Developing and enhancing usable HIT is critical to promoting equitable health service delivery and high-quality care in Africa. Early-stage evaluations (stages 1 and 2) and interactions (types 0 and 1) should receive special attention to ensure HIT usability prior to implementing HIT in the field.

Ongoing Efforts to Improve Antimicrobial Utilization in Hospitals among African Countries and Implications for the Future

There are serious concerns with rising antimicrobial resistance (AMR) across countries increasing morbidity, mortality and costs. These concerns have resulted in a plethora of initiatives globally and nationally including national action plans (NAPs) to reduce AMR. Africa is no exception, especially with the highest rates of AMR globally. Key activities in NAPs include gaining a greater understanding of current antimicrobial utilization patterns through point prevalence surveys (PPS) and subsequently instigating antimicrobial stewardship programs (ASPs). Consequently, there is a need to comprehensively document current utilization patterns among hospitals across Africa coupled with ASP studies. In total, 33 PPS studies ranging from single up to 18 hospitals were documented from a narrative review with typically over 50% of in-patients prescribed antimicrobials, up to 97.6% in Nigeria. The penicillins, ceftriaxone and metronidazole, were the most prescribed antibiotics. Appreciable extended prescribing of antibiotics up to 6 days or more post-operatively was seen across Africa to prevent surgical site infections. At least 19 ASPs have been instigated across Africa in recent years to improve future prescribing utilizing a range of prescribing indicators. The various findings resulted in a range of suggested activities that key stakeholders, including governments and healthcare professionals, should undertake in the short, medium and long term to improve future antimicrobial prescribing and reduce AMR across Africa.

Determinants of the Empiric Use of Antibiotics by General Practitioners in South Africa: Observational, Analytic, Cross-Sectional Study

The overuse of antibiotics is the main driver of antimicrobial resistance (AMR). However, there has been limited surveillance data on AMR and antibiotic prescribing at a primary healthcare level in South Africa. An observational, analytic, cross-sectional study was undertaken to assess key factors associated with empiric antibiotic prescribing among private sector general practitioners (GPs) in the eThekwini district in South Africa, particularly for patients with acute respiratory infections (ARIs). A semi-structured web-based questionnaire was used between November 2020−March 2021. One hundred and sixteen (55.5%) responding GPs prescribed antibiotics empirically for patients with ARIs more than 70% of the time, primarily for symptom relief and the prevention of complications. GPs between the ages of 35−44 years (OR: 3.38; 95%CI: 1.15−9.88), >55 years (OR: 4.75; 95% CI 1.08−21) and in practice < 15 years (OR: 2.20; 95%CI: 1.08−4.51) were significantly more likely to prescribe antibiotics empirically. Three factors—workload/time pressures; diagnostic uncertainty, and the use of a formulary, were significantly associated with empiric prescribing. GPs with more experience and working alone were slightly less likely to prescribe antibiotics empirically. These findings indicate that a combination of environmental factors are important underlying contributors to the development of AMR. As a result, guide appropriate interventions using a health system approach, which includes pertinent prescribing indicators and targets.

A national, multicentre web-based point prevalence survey of antimicrobial use in community healthcare centres across South Africa and the implications

OBJECTIVE

Up to 90% of antimicrobials globally are prescribed and dispensed in ambulatory care. However, there are considerable gaps regarding the extent and rationale for their use especially in low- and middle-income countries such as South Africa. Point prevalent surveys (PPS) are useful to determine current prescribing patterns, identify targets for quality improvement and evaluate the effectiveness of antimicrobial stewardship programmes (ASPs) within institutions. Consequently, the objective of this study was to undertake a PPS within community healthcare centers (CHCs) in South Africa given their importance to the public healthcare system. The findings will be used to provide guidance on future interventions to improve antimicrobial use in South Africa and wider.

METHODS

A PPS of antimicrobial consumption was undertaken among patients attending 18 CHCs in South Africa. A web-based application was used to record the utilization data, with utilization assessed against World Health Organization (WHO) and South African guidelines.

RESULTS

The overall prevalence of antimicrobial use amongst patients attending the CHCs was 21.5% (420 of 1958 patients). This included one or more antimicrobials per patient. The most frequently prescribed antimicrobials were amoxicillin (32.9%), isoniazide (11.3%) and a combination of rifampicin, isoniazid, pyrazinamide and ethambutol (Rifafour®) (10.5%), with the majority from the WHO Access list of antibiotics. There was high adherence to guidelines (93.4%). The most common indication for antibiotics were ear, nose and throat infections (22.8%), with no culture results recorded in patients' files.

CONCLUSIONS

It's encouraging to see high adherence to South African guidelines when antimicrobials were prescribed, with the majority taken from the WHO Access list. However, there were concerns with appreciable prescribing of antimicrobials for upper respiratory tract infections that are essentially viral in origin, and a lack of microbiological testing. The establishment of ASPs can help address identified concerns through designing and implementing appropriate interventions.

A web-based point prevalence survey of antimicrobial use and quality indicators at Raleigh Fitkin Memorial Hospital in the Kingdom of Eswatini and the implications

OBJECTIVES

Currently there is limited knowledge regarding antimicrobial utilization patterns among public hospitals in Eswatini. This is a concern given rising resistance rates among African countries. This study aimed to address this by determining antimicrobial utilization patterns using a point prevalence survey (PPS) methodology at Raleigh Fitkin Memorial (RFM) Hospital. The findings would be used to identify potential interventions to improve future antimicrobial utilization.

METHOD

A PPS was conducted using a web-based application (App). Antimicrobials were categorized according to the World Health Organization (WHO) Access, Watch, and Reserve (AWaRe) classification. Each ward in the hospital was surveyed in one day using patient files. All patients in the ward, admitted by 08h30 on the day of the survey, were included. Ethical clearance was granted by the university and at country level.

RESULTS

Overall, 68 patient files in 12 wards were surveyed, with 88.2% (60/68) receiving at least one antimicrobial. The most widely prescribed antimicrobials were amoxicillin (24.3%), and ceftriaxone IV (21.6%), mostly from the Access group (69.9%), and zero from the Reserve group. In the past 90 days prior to admission, most patients (60.3%; 41/68) were not receiving any antimicrobials. Of concern was that antimicrobial use was empirical for all patients (100%) with mostly parenteral administration (88.3%; 91/103). In addition, the majority of surgical prophylaxis patients (80%; 12/15) were given an extended course post surgery. There was also no documented switch or stop dates, or patient culture and drug sensitivity results.

CONCLUSION

Antimicrobial utilization is high at RFM hospital. Identified targets for quality improvement programs include encouraging earlier switching to oral antimicrobials, reducing extended use for surgical prophylaxis and encouraging greater sensitivity testing and documentation stop dates. The development of the App appreciably reduced data collection times and analysis, and would be recommended for use in other public hospitals.

Tackling antimicrobial resistance across sub-Saharan Africa: current challenges and implications for the future

INTRODUCTION

Antimicrobial resistance (AMR) is a concern as this increases morbidity, mortality, and costs, with sub-Saharan Africa having the highest rates globally. Concerns with rising AMR have resulted in international, Pan-African, and country activities including the development of national action plans (NAPs). However, there is variable implementation across Africa with key challenges persisting.

AREAS COVERED

Consequently, there is an urgent need to document current NAP activities and challenges across sub-Saharan Africa to provide future guidance. This builds on a narrative review of the literature.

EXPERT OPINION

All surveyed sub-Saharan African countries have developed their NAPs; however, there is variable implementation. Countries including Botswana and Namibia are yet to officially launch their NAPs with Eswatini only recently launching its NAP. Cameroon is further ahead with its NAP than these countries; though there are concerns with implementation. South Africa appears to have made the greatest strides with implementing its NAP including regular monitoring of activities and instigation of antimicrobial stewardship programs. Key challenges remain across Africa. These include available personnel, expertise, capacity, and resources to undertake agreed NAP activities including active surveillance, lack of focal points to drive NAPs, and competing demands and priorities including among donors. These challenges are being addressed, with further co-ordinated efforts needed to reduce AMR.

Challenges and Innovations Brought about by the COVID-19 Pandemic Regarding Medical and Pharmacy Education Especially in Africa and Implications for the Future

BACKGROUND

Multiple measures introduced early to restrict COVID-19 have dramatically impacted the teaching of medical and pharmacy students, exacerbated by the lack of infrastructure and experience with e-learning at the start of the pandemic. In addition, the costs and reliability of the Internet across Africa pose challenges alongside undertaking clinical teaching and practical programmes. Consequently, there is a need to understand the many challenges and how these were addressed, given increasingly complex patients, to provide future direction.

METHOD

An exploratory study was conducted among senior-level medical and pharmacy educators across Africa, addressing four key questions, including the challenges resulting from the pandemic and how these were dealt with.

RESULTS

Staff and student members faced multiple challenges initially, including adapting to online learning. In addition, concerns with the lack of equipment (especially among disadvantaged students), the costs of Internet bundles, and how to conduct practicals and clinical teaching. Multiple activities were undertaken to address these challenges. These included training sessions, developing innovative approaches to teaching, and seeking ways to reduce Internet costs. Robust approaches to practicals, clinical teaching, and assessments have been developed.

CONCLUSIONS

Appreciable difficulties to teaching arising from the pandemic are being addressed across Africa. Research is ongoing to improve education and assessments.

A national, multicentre web-based point prevalence survey of antimicrobial use and quality indices among hospitalised paediatric patients across South Africa

OBJECTIVES

Data on antimicrobial consumption among the paediatric population in public hospitals in South Africa is limited. These needs to be addressed to improve future use and reduce antimicrobial resistance rates. Consequently, the objective is to quantify antimicrobial usage;and identify and classify which antimicrobials are used in the peadiatric population in public sector hospitals in South Africa according to World Health Organiosation (WHO) AWaRe list of antimicrobials METHODS: Conduct a point prevalence survey among 18 public sector hospitals from nine provinces using a newly developed web-based application. The data will be analysed according to the WHO AwaRe list to guide future quality improvement programmes.

RESULTS

1261 paediatric patient files were reviewed with 49.7% (627/1261) receiving at least one antimicrobial, with 1013 antimicrobials prescribed overall. The top five antimicrobials included ampicillin (16.4%), gentamycin (10.0%), amoxicillin and enzyme inhibitor (9.6%), ceftriaxone (7.4%), and amikacin (6.3%). Antimicrobials from the Access classification were the most used (55.9%) with 3.1% being from the Reserve classification. The most common infectious conditions were pneumonia (21.3%; 148/1013) and clinical sepsis (16.0%; 111/1013). Parenteral administration (75.6%) and prolonged surgical prophylaxis (66.7%; 10/15) were common and concerns. 28% of the paediatric patients had cultures requested for them before antimicrobial treatment (284/1013) however only 38.7% (110/284) of culture results were available in the files.

CONCLUSION

Overall, antimicrobial prescribing is common among paediatric patients in South Africa. Interventions should be targeted at improving antimicrobial prescribing, including surgical prophylaxis, and encouraging greater use of oral antibiotics.

Antimicrobial Stewardship Activities in Public Healthcare Facilities in South Africa: A Baseline for Future Direction

Antimicrobial resistance (AMR) is a growing problem worldwide, including South Africa, where an AMR National Strategy Framework was implemented to instigate antimicrobial stewardship programmes (ASPs) and improve antimicrobial prescribing across sectors. To address the need to assess progress, a sequential mixed methodology with an explanatory research design was employed. In Phase 1, a self-administered questionnaire was completed by healthcare professionals (HCPs) from 26 public sector healthcare facilities across South Africa to assess compliance with the Framework. The results were explored in Phase 2 through 10 focus group discussions and two in-depth interviews, including 83 participants. Emerging themes indicated that public healthcare facilities across South Africa are facing many challenges, especially at entry level primary healthcare (PHC) facilities, where antimicrobial stewardship activities and ASPs are not yet fully implemented. Improved diagnostics and surveillance data are a major shortcoming at these facilities. Continuous education for HCPs is deficient, especially for the majority of prescribers at PHC level and health campaigns are nearly non-existent. Involvement and visibility of management at certain facilities is a serious shortfall. Consequently, it is important to call attention to the challenges faced with improving antimicrobial prescribing across countries and address these to reduce AMR, especially in PHC facilities, being the first point of access to healthcare for the vast majority of patients in developing countries.

A multicentre point prevalence study of antibiotics utilization in hospitalized patients in an urban secondary and a tertiary healthcare facilities in Nigeria: findings and implications

OBJECTIVES

The understanding of antimicrobial utilization patterns is pertinent to successful implementation of the National Action Plans on Antimicrobial Resistance (AMR). There is, however, limited information on antibiotics utilization in Nigeria. This study was undertaken to build on existing information and provide direction for appropriate interventions including Antibiotics Stewardship Programs (ASP).

METHOD

A Point Prevalence Study (PPS) was conducted in two public urban health facilities in Lagos, Nigeria using a design adapted from the European Center for Disease Prevention and Control (ECDC) and Global-PPS surveys.

RESULTS

The prevalence of antibiotics use was 80.6% administered mostly parenterally (83.1% of total prescriptions) with concerns with extended surgical antibiotics prophylaxis. The mostly used antibiotics in the secondary hospital were parenteral metronidazole (32.4%), ceftriaxone (27.5%), and amoxicillin + clavulanate (8.2%) while the mostly used in the tertiary hospital were ceftriaxone (25.3%), parenteral metronidazole (19.1%), and amoxicillin + clavulanate (9.3%). There was an appreciable lack of specific functional capacities, policies, and processes to promote appropriate antimicrobial use in both hospitals.

CONCLUSIONS

There is high rate of antibiotics utilization in these facilities with lack of institutional frameworks and processes for ensuring appropriate antibiotic use. The study provides the information needed to improve future antimicrobial use in hospitals and reduce AMR.

Strategies to Improve Antimicrobial Utilization with a Special Focus on Developing Countries

Antimicrobial resistance (AMR) is a high priority across countries as it increases morbidity, mortality and costs. Concerns with AMR have resulted in multiple initiatives internationally, nationally and regionally to enhance appropriate antibiotic utilization across sectors to reduce AMR, with the overuse of antibiotics exacerbated by the COVID-19 pandemic. Effectively tackling AMR is crucial for all countries. Principally a narrative review of ongoing activities across sectors was undertaken to improve antimicrobial use and address issues with vaccines including COVID-19. Point prevalence surveys have been successful in hospitals to identify areas for quality improvement programs, principally centering on antimicrobial stewardship programs. These include reducing prolonged antibiotic use to prevent surgical site infections. Multiple activities centering on education have been successful in reducing inappropriate prescribing and dispensing of antimicrobials in ambulatory care for essentially viral infections such as acute respiratory infections. It is imperative to develop new quality indicators for ambulatory care given current concerns, and instigate programs with clear public health messaging to reduce misinformation, essential for pandemics. Regular access to effective treatments is needed to reduce resistance to treatments for HIV, malaria and tuberculosis. Key stakeholder groups can instigate multiple initiatives to reduce AMR. These need to be followed up.

A point prevalence survey of antimicrobial utilisation patterns and quality indices amongst hospitals in South Africa; findings and implications

Objectives: Antimicrobial use is growing, driven mainly by rising demands in developing countries. Knowing how antimicrobials are prescribed is important. Consequently, we undertook a point prevalence survey (PPS) quantifying antimicrobial consumption among 18 public sector hospitals across South Africa.Method: A purpose-built web-based application was used to collect PPS data.Results: Out of 4407 adult patients surveyed, 33.6% were treated with an antimicrobial. The most frequently prescribed groups were a combination of penicillins including β-lactamase inhibitors. Amoxicillin combined with an enzyme inhibitor accounted for 21.4% total DDDs. In the medical and surgical wards, Access antimicrobials (54.1%) were mostly used, while in the ICU, Watch antimicrobials (51.5%) were mostly used. Compliance with the South African Standard Treatment Guidelines and Essential Medicines List was 90.2%; however, concerns with extended use of antimicrobials for surgical prophylaxis (73.2% of patients).Conclusion: The web-based PPS tool was easy to use and successful in capturing PPS data since the results were comparable to other PPS studies across Africa. High use of amoxicillin combined with an enzyme inhibitor, possibly because it was among the broad-spectrum antimicrobials in the Access group. The findings will assist with future targets to improve antimicrobial prescribing among public sector hospitals in South Africa.
