Background: Tanzania’s primary healthcare system suffers from a scarcity of financial and human resources that impedes its effectiveness to deliver dependable and uniform quality healthcare. Adherence to standard treatment guidelines (STG) can help provide more consistent and correct diagnoses and treatments and limit the irrational use of medicines and the negative health consequences that can occur as a result. The purpose of this study was to investigate prescribers’ adherence of their diagnoses and respective treatments to national STG and to identify potential areas for planning interventions. Methods: A cross-sectional study on prescribers’ adherence to diagnosis and treatment, according to national STG, was conducted in 2012 in public primary healthcare facilities (HCF) in the Dodoma region of Tanzania. Information on 2886 patients was collected, prospectively and retrospectively, from 120 HCF across the Dodoma region using a structured questionnaire. Twenty-five broadly defined main illness groups were recorded and the nine most prevalent and relevant conditions were statistically analysed in detail. Results: Diagnoses and related treatments were recorded and analysed in 2872 cases. The nine most prevalent conditions were upper respiratory tract infections (25%), malaria (18%), diarrhoea (9.9%), pneumonia (6.1%), skin problems (5.8%), gastrointestinal diagnoses (5%), urinary tract infections (4%), worm infestations (3.6%) and eye problems (2.1%). Only 1.8% of all diagnoses were non-communicable diseases. The proportion of prescribers’ primary diagnoses that completely adhered to national STG was 599 (29.9%), those that partially adhered totalled 775 (38.7%), wrong medication was given in 621 cases (30.9%) and no diagnosis or medication was given in nine cases (0.5%). Sixty-one percent of all patients received an antibiotic regardless of the diagnoses. Complete adherence was highest when worms were diagnosed and lowest for diarrhoea. The proportion of cases that did not adhere to STG was highest with patients with skin problems and lowest for malaria. Conclusion: Prescribers’ general adherence to national STG in primary HCF in the public sector in Dodoma region is sub-optimal. The reasons are multifaceted and focused attention, directed at improving prescribing and pharmacotherapy, is required with a view of improving patient care and health outcomes.

The availability of medicines in public health facilities in Tanzania is problematic. Medicines shortages are often caused by unavailability at Medical Stores Department, the national supplier for public health facilities. During such stock-outs, districts may purchase from private suppliers. However, this procedure is intransparent, bureaucratic and uneconomic. To complement the national supply chain in case of stock-outs with a simplified, transparent and efficient procurement procedure based on a public-private partnership approach with a prime vendor at the regional level. To develop a successful pilot of a Prime Vendor system with the potential for national scale-up. A public-private partnership was established engaging one private sector pharmaceutical supplier as the Prime Vendor to provide the complementary medicines needed by public health facilities in Tanzania. The Dodoma pilot region endorsed the concept involving the private sector, and procedures to procure complementary supplies from a single vendor in a pooled regional contract were developed. A supplier was tendered and contracted based on Good Procurement Practice. Pilot implementation was guided by Standard Operating Procedures, and closely monitored with performance indicators. A 12-step approach for national implementation was applied including cascade training from national to facility level. Each selected vendor signed a contract with the respective regional authority. In the pilot region, tracer medicines availability increased from 69% in 2014 to 94% in 2018. Prime vendor supplies are of assured quality and average prices are comparable to prices of Medical Stores Department. Procurement procedures are simplified, shortened, standardized, transparent and well-governed. Procurement capacity was enhanced at all levels of the health system. Proven successful, the Prime Vendor system pilot was rolled-out nationally, on government request, to all 26 regions of mainland Tanzania, covering 185 councils and 5381 health facilities. The Prime Vendor system complements regular government supply through a regional contract approach. It is anchored in the structures of the regional health administration and in the decentralisation policy of the country. This partnership with the private sector facilitates procurement of additional supplies within a culture of transparency and accountability. Regional leadership, convincing pilot results and policy dialogue have led to national roll-out. Transferring this smaller-scale supply chain intervention to other regions requires country ownership and support for sustainable operations.

Background: Access to safe, effective, quality and affordable essential medicines for all is a central component of Universal Health Coverage (UHC). However, the availability of quality medicines in peripheral healthcare facilities is often limited. Several countries have developed integrated complementary pharmaceutical supply systems to address the shortage of medicines. Nevertheless, there is little evidence on how accountability contributes to the performance of such complementary pharmaceutical supply systems in low-income settings. The current study analyses how accountability mechanisms contributed to the performance of Jazia Prime Vendor System (Jazia PVS) in Tanzania. Methods: The study analysed financial, performance and procedure accountability as defined in Boven’s accountability framework. We conducted 30 in-depth interviews (IDIs), seven group discussions (GD) and 14 focus group discussions (FGDs) in 2018 in four districts that implemented Jazia PVS. We used a deductive and inductive approach to develop the themes and framework analysis to summarize the data. Results: The study findings revealed that a number of accountability mechanisms implemented in conjunction with Jazia PVS contributed to the performance of Jazia PVS. These include inventory and financial auditing conducted by district pharmacists and the internal auditors, close monitoring of standard operating procedures by the prime vendor regional coordinating office and peer cascade coaching. Furthermore, the auditing activities allowed identifying challenges of delayed payment to the vendor and possible approaches for mitigation while peer cascade coaching played a crucial role in enabling staff at the primary facilities to improve skills to oversee and manage the medicines supply chain. Conclusion: Financial, performance and procedure accountability measures played an important role for the successful performance of Jazia PVS in Tanzania. The study highlights the need for capacity building linked to financial and supply management at lower level health facilities, including health facility governing committees, which are responsible for priority-setting and decision-making at facility level.

Background: In Tanzania, the Medical Stores Department is the principal pharmaceutical provider to public health facilities throughout the country. However, growing demand from health facilities has proved difficult to satisfy and stock-outs at health facilities are frequent. The aim of the current study was to conduct a situation analysis of the procedures and practices of procuring medicines and medical supplies from private suppliers in the Dar es Salaam region when those commodities are unavailable at the Medical Stores Department. Methods: A mixed-method approach including qualitative and quantitative methods was applied to understand procurement procedures and practices and private suppliers’ performance at district level. Qualitative interviews with suppliers and district authorities, and a review of inventory documents at store level was conducted between February and March 2018. The quantitative approach included a review and analyses of relevant procurement documents from the 2016/2017 financial year to explore the funds used to procure health commodities from the private sector. The ten most frequently mandated private suppliers were assessed in more detail focusing on cost, quality and availability of medicines and lead times and delivery. Results: A lack of consistency and written guidelines for procuring medicines and medical supplies from the private sector was observed. The procurement process was bureaucratic and lengthy requiring multiple steps between health facilities, suppliers and district authorities. A significant number of people were involved requiring a minimum of 13 signatures and 16 steps from order preparation to approval. Only 17 of 77 prequalified private suppliers received orders from public health facilities. The criteria for choosing which supplier to use were unclear. Completed orders amounted to USD 663,491. The bureaucratic process drove councils and healthcare facilities towards alternative ways to procure health commodities when Medical Stores Department stock-outs occurred. Conclusion: The procurement procedure outside the Medical Stores Department is inefficient and cumbersome, often circumventing government regulations. General lack of accountability renders the process susceptible to leakage of funds and medicines. Increasing the transparency and efficiency of procurement procedures from the private sector with a prime vendor system would help to better manage Medical Stores Department stock-outs and help improve health care services overall.

We explored the outcomes and challenges encountered during a 12-year collaborative development endeavor in Tanzania, focused on enhancing the healthcare system. The Health Promotion and System Strengthening (HPSS) project, supported by the Swiss Government and implemented by the Swiss Tropical and Public Health Institute (Swiss TPH) from 2011 to 2023, aimed to strengthen various aspects of Tanzania’s healthcare landscape. This included reforms in health insurance through the improved Community Health Fund (iCHF), the establishment of a public–private partnership to optimize the health commodity supply chain via a Prime Vendor System (Jazia PVS), the implementation of health technology management innovations, and the facilitation of participatory community and school health promotion initiatives. Operating in a multisectoral, interdisciplinary, and systemic manner, the HPSS project employed a variety of interconnected strategies, focusing on key entry points within the Tanzanian health system, starting from district level to national policies. These efforts followed a three-stages approach to reach a sustainable adoption of the innovations, going through the process of service and product innovation, integration into service delivery systems, and finally their adoption in the respective institutional policies. Each stage presented distinct frameworks and challenges, detailed in this article. The development of innovative concepts was complemented by capacity building through on-the-job training, establishment of new accredited training programs for pre-service trainings, and the development of new IT systems integrated into the governmental IT environment, as well as efforts to improve transparency, accountability, and governance. Activities in these fields were guided by operational research, following the translational approach of Swiss TPH to go from innovation and validation to application. The example of the HPSS project highlights the cycle of developing and testing innovations at the community and district level, followed by endeavoring national-level integration and policy adjustments, consequently resulting in improved service delivery at the district and community level.

Schoolchildren are in their formative years, and therefore at an ideal stage in their lives to take in knowledge and best practices that will guide their future behavior. Through the Roll Back Antimicrobial Resistance (RBA) Initiative in Tanzania, antimicrobial resistance (AMR) School Clubs have successfully educated and empowered schoolchildren to become antibiotic guardians and AMR champions. Using appropriate language and consideration of the local context, the project has employed a variety of innovative activities, including AMR arts and crafts, competitions, storytelling and interactive learning that would teach children in an engaging and enjoyable manner. The School Club project has demonstrated how a mix of fun-based knowledge and skills transfer methods and rewarding competitions can change antimicrobial use knowledge and practice in schoolchildren.
