Impact of differentiated service delivery models on retention in HIV care and viral suppression among people living with HIV in sub-Saharan Africa: A systematic review and meta-analysis of randomised controlled trials.

Differentiated service delivery (DSD) models, such as adherence clubs (ACs), are client-centred approaches where clinically stable people living with HIV (PLHIV) meet to receive various services, including psychosocial support, brief symptoms screening, and refills of antiretroviral medications, among others. We conducted a review to assess the impact of DSD models, including ACs, on sustaining retention in care (RC) and achieving viral suppression (VS) among PLHIV in sub-Saharan Africa. The review protocol was registered in PROSPERO (CRD42023418988). We searched the literature from PubMed, Scopus, Web of Science, Embase and Google Scholar from their inception through May 2023. Eligible randomised controlled trials of adherence clubs were reviewed to assess impact on retention and viral suppression. Random effect models were used to estimate the risk ratios (RR) and 95% confidence intervals (CI). The literature search yielded a total of 1596 records of which 16 randomised clinical trials were determined to be eligible. The trials were conducted in diverse populations among adults and children with a total of 13,886 participants. The RR between any DSD models and standard of care (SoC) was 1.09 (95% CI: 1.08-1.11, I2 : 0%, p: <0.96) and 1.01 (95% CI: 1.00-1.02, I2 : 0%, p: <0.85) for RC and VS, respectively. The RR between ACs and SoC was 1.01 (95% CI: 0.96-1.07, I2 : 84%, p: <0.01) and 1.02 (95% CI: 0.98-1.07, I2 : 77%, p: <0.01) for RC and VS, respectively. DSD models, including ACs, show comparable effectiveness to SoC in maintaining care and achieving viral suppression for stable PLHIV. To maximise adoption, an implementation science approach is crucial for designing effective strategies and overcoming challenges.

Implementation research for promoting access and rational use of antibiotics for children: lessons learnt from Tanzania.

Implementation research (IR) has proved to be a potential catalyst in facilitating the uptake of evidence-based innovations into routine practices and thereby maximizing public health outcomes. IR not only focuses on the effectiveness of the innovations but also identifies and addresses the barriers and facilitators to maximize their uptake into routine practices. This article describes the processes undertaken to implement a research project aimed at promoting access and rational use of antibiotics for children (PARAC). It also provides an overview of the lessons learnt during its implementation in Tanzanian hospital and community settings.

WHO/INRUD prescribing indicators among tertiary regional referral hospitals in Dar es Salaam, Tanzania: a call to strengthen antibiotic stewardship programmes.

Background: Antibiotic prescribing should be guided by national essential medicines lists (NEMLs) and treatment guidelines; however, there are inadequate data on antibiotic utilization patterns in tertiary hospitals in Tanzania. This study aimed to determine antibiotic prescribing patterns in tertiary hospitals in Dar es Salaam, Tanzania. Methods: A retrospective cross-sectional study was conducted in three regional referral hospitals. About 200 prescription records from 2020 to 2022 were analysed at each hospital for prescribing patterns using WHO/ International Network of Rational Use of Drugs (INRUD) indicators (1993) and the AWaRe 2021 classification. Factors associated with receiving an antibiotic prescription were assessed using a logistic regression model. Facilities were ranked on prescribing practices using the index of rational drug prescribing (IRDP). Results: A total of 2239 drugs were prescribed, of which 920 (41.1%) were antibiotics. An average of 3.7 ±â€Š1.5 (optimal: 1.6-1.8) total medicines and 1.53 ±â€Š0.78 antibiotics were prescribed per patient. About 88.0% (528) of the prescriptions contained antibiotics (optimal: 20.0%-26.8%), while 78.2% (413) of all antibiotic prescriptions contained injections (optimal: 13.4%-24.1%). Furthermore, 87.5% (462) of the antibiotics were prescribed in generic names (optimal: 100%), while 98.7% (521) conformed to the NEML (optimal: 100%). Metronidazole was the most frequently prescribed antibiotic (39.2%; n = 134), followed by ceftriaxone (37.1%, n = 127) and amoxicillin/clavulanic acid (8.5%, n = 29). Conclusions: We found substantial empirical prescribing and overuse of antibiotics exceeding WHO recommendations. Antibiotic overuse varied across the hospitals. Being male, having underlying conditions such as diabetes mellitus, and/or being treated at Temeke hospital were associated with receiving an antibiotic prescription. We recommend strengthening antibiotic stewardship programmes in the studied facilities.

The public health sector supply chain costs in Tanzania.

Tanzania's supply chain system is a complicated web of integrated and vertical systems, covering essential and vertical programs health commodities, laboratory and diagnostics, equipment, and supplies. Despite significant improvement in the supply chain over the decades, the availability of medicines has remained uneven. Therefore, identifying the cost of operating the supply chain is vital to facilitate allocation of adequate finances to run the supply chain. We adopted a three-step approach to costing, which included i) identification, ii) measurement, and (iii) valuation of the resource use. Two levels of the Tanzanian supply chain system were examined to determine the cost of running the supply chain by function. These included first the Medical Stores Department (MSD) central and zonal level, secondly the health service delivery level that include National, Zonal and regional hospitals and the Primary Health Care (District Hospital, health center and Dispensary). The review adopted the health system perspective, whereby all resources consumed in delivering health commodities were considered, resource use was then classified as financial and economic costs. The costing period was an average of two financial years, 2015/16 and 2016/17. The cost data were exchanged from Tanzania Shillings to 2017 US$ and then adjusted for inflation to 2020 US$. The study used the total sales reported in audited financial accounts for throughput value. The average annual costs of running the supply chain at the central MSD was estimated at USD$ 15.5 million and US$ 4.1 million at the four sampled MSD Zonal branches. There is a wide variation in annual running costs among MSD zonal branches; the supply chain's unit cost was highest in the Dodoma zone and lowest in the Mwanza zone at 26% and 8%, respectively. When examined on a cost-per-unit basis, supply chain systems operate at sub-optimal levels at health facilities at a unit cost of 37% per unit of commodity throughput value. There are inefficiencies in supply chain financing in Tanzania. Storage costs are higher than distribution costs, this may imply some efficiency gains. MSD should employ a "just in time" inventory model, reducing the inventory holding costs, including the high-expired commodities holding charge, this could be improved by increasing the order fill rate.
