How are global health policies transferred to sub-Saharan Africa countries? A systematic critical review of literature

Suitability of paediatric legislation beyond the USA and Europe: a qualitative study on access to paediatric medicines

Background

Paediatric legislation has contributed to better access to appropriate treatments in the European Union and the USA by requiring paediatric research in return for financial incentives. This study explored whether similar policies could improve access to medicines in other countries.

Methods

We conducted 46 interviews with representatives from healthcare practice, patient organisations and health authorities from six countries (Australia, Brazil, Canada, Kenya, Russia and South Africa) as well as multinational pharmaceutical companies exploring their views regarding access barriers to paediatric medicines. Emphasis was placed on regulation-related barriers and the effect of the COVID-19 pandemic. Where participants were familiar with paediatric legislation, views regarding its relevance for domestic context were explored in depth.

Results

Insufficient paediatric research and development, regulatory hurdles and reimbursement constraints were reported to be relevant access barriers in all studied settings. In the absence of marketing registration or reimbursement, access to paediatric medicines was associated with increased legal, financial and informational barriers. Brazil, Kenya, Russia and South Africa additionally described overarching deficiencies in medicines provision systems, particularly in procurement and supply. The COVID-19 pandemic was said to have reduced regulatory hurdles while further heightening global access inequalities.Views regarding paediatric legislation were mixed. Concerns regarding the implementation of such policies focused on regulatory resource constraints, enforceability and potential reduction of industry activity.

Conclusions

The study findings suggest that paediatric legislation may be most impactful in mature health systems and should be accompanied by measures addressing access barriers beyond marketing registration. This could include strengthening domestic manufacturing capacities and technology transfer for medicines with high public health relevance. Ideally, legislative changes would build on global harmonisation of paediatric legislation, which could be achieved through existing WHO structures.

Engaging Community Health Workers (CHWs) in Africa: Lessons from the Canadian Red Cross supported programs

Universal Health Coverage (UHC) will not be achieved if health care worker shortages, estimated to increase to 18 million by 2030, are not addressed rapidly. Community-based health systems, which pivot to effective engagement of community health workers (CHW), may have an essential role in linking communities with health care facilities and reducing unmet health services needs caused by these shortages. The Canadian Red Cross (CRC) has partnered with different National Red Cross/Red Crescent Societies and Ministries of Health in Africa in the implementation of programs where CHWs contributed to the provision of various health services. This study reports on key findings (i.e., beneficiaries reached, CHWs engaged, programs implemented, intervention outcomes) and lessons learned from CRC supported CHW programs in Africa over the last 15 years (2007-2022). Qualitative methodology was employed to conduct document analysis on 17 sets of reports from each CRC-supported community health worker project in Africa over the past 15 years. Focus was on identifying challenges, facilitators, and lessons learned. CRC supported projects have trained over 9000 CHWs, benefiting nearly 7.5 million people across Africa. Key success factors include adaptability and agility in programming and project management, and considering contextual factors (political, social, and cultural systems). Investing in essential training for CHWs, staff, and volunteers is crucial, alongside employing an evidence-based approach to inform all aspects of programming and implementation. Additionally, projects prioritizing protection, gender and inclusion (PGI) while leveraging existing community structures and partnerships important for successful implementation. Despite challenges (i.e., weak health systems, lack of political commitment, insufficient funding, inadequate training) CHWs are recognized as crucial in promoting community-based health, improving access to care, addressing disparities, and contributing to achieving (UHC). Their unique position within communities enables them to provide culturally appropriate and localized primary health care- particularly in remote, resource limited and poverty-stricken regions.

Adherence to evidence-based implementation of antimicrobial treatment guidelines among prescribers in sub-Saharan Africa: a systematic review and meta-analysis

BACKGROUND

Adherence to evidence-based standard treatment guidelines (STGs) enable healthcare providers to deliver consistently appropriate diagnosis and treatment. Irrational use of antimicrobials significantly contributes to antimicrobial resistance in sub-Saharan Africa (SSA).  The best available evidence is needed to guide healthcare providers on adherence to evidence-based implementation of STGs. This systematic review and meta-analysis aimed to determine the pooled prevalence of adherence to evidence-based implementation of antimicrobial treatment guidelines among prescribers in SSA.

METHODS

The review followed the JBI methodology for systematic reviews of prevalence data. CINAHL, Embase, PubMed, Scopus, and Web of Science databases were searched with no language and publication year limitations. STATA version 17 were used for meta-analysis. The publication bias and heterogeneity were assessed using Egger's test and the I2 statistics. Heterogeneity and publication bias were validated using Duval and Tweedie's nonparametric trim and fill analysis using the random-effect analysis. The summary prevalence and the corresponding 95% confidence interval (CI) of healthcare professionals' compliance with evidence-based implementation of STG were estimated using random effect model. The review protocol has been registered with PROSPERO code CRD42023389011. The PRISMA flow diagram and checklist were used to report studies included, excluded and their corresponding section in the manuscript.

RESULTS

Twenty-two studies with a total of 17,017 study participants from 14 countries in sub-Saharan Africa were included. The pooled prevalence of adherence to evidence-based implementation of antimicrobial treatment guidelines in SSA were 45%. The pooled prevalence of the most common clinical indications were respiratory tract (35%) and gastrointestinal infections (18%). Overall prescriptions per wards were inpatients (14,413) and outpatients (12,845). Only 391 prescribers accessed standard treatment guidelines during prescription of antimicrobials.

CONCLUSIONS

Healthcare professionals' adherence to evidence-based implementation of STG for antimicrobial treatment were low in SSA. Healthcare systems in SSA must make concerted efforts to enhance prescribers access to STGs through optimization of mobile clinical decision support applications. Innovative, informative, and interactive strategies must be in place by the healthcare systems in SSA to empower healthcare providers to make evidence-based clinical decisions informed by the best available evidence and patient preferences, to ultimately improving patient outcomes and promoting appropriate antimicrobial use.
