Mid-level healthcare workers knowledge on non-communicable diseases in Tanzania: a district-level pre-and post-training assessment.

INTRODUCTION: Over the past two decades, Tanzania's burden of non-communicable diseases has grown disproportionately, but limited resources are still prioritized. A trained human resource for health is urgently needed to combat these diseases. However, continuous medical education for NCDs is scarce. This paper reports on the mid-level healthcare workers knowledge on NCDs. We assessed the knowledge to measure the effectiveness of the training conducted during the initiation of a Package for Essential Management of Severe NCDs (PEN Plus) in rural district hospitals in Tanzania. METHODS: The training was given to 48 healthcare employees from Dodoma Region's Kondoa Town Council District Hospital. For a total of five (5) days, a fundamental course on NCDs featured in-depth interactive lectures and practical workshops. Physicians from Tanzania's higher education institutions, tertiary university hospitals, research institutes, and medical organizations served as trainers. Before and after the training, a knowledge assessment comprising 28 questions was administered. Descriptive data analysis to describe the characteristics of the specific knowledge on physiology, diagnosis and therapy of diabetes mellitus, rheumatic fever, heart disease, and sickle cell disease was done using Stata version 17 (STATA Corp Inc., TX, USA). RESULTS: Complete assessment data for 42 out of the 48 participants was available. Six participants did not complete the training and the assessment. The mean age of participants was 36.9 years, and slightly above half (52%) were above 35 years. Two-thirds (61.9%) were female, and about half (45%) were nurses. The majority had the experience of working for more than 5 years, and the average was 9.4 years (+/- 8.4 years). Overall, the trainees' average scores improved after the training (12.79 vs. 16.05, p < 0.0001) out of 28 possible scores. Specifically, trainees' average scores were better in treatment than in diagnosis, except for sickle cell disease (1.26 vs. 1.83). Most were not able to diagnose rheumatic heart disease (47.6% able) compared to diabetes mellitus (54.8% able) or sickle cell disease (64.3% able) at baseline. The proportion of trainees with adequate knowledge of the treatment of sickle cell disease and diabetes mellitus was 35% and 38.1%, respectively, and there was a non-statistical difference after training. Those working for less than 5 years had a higher proportion of adequate knowledge (30.8%) compared to their more experienced colleagues (6.9%). After the training, participants' knowledge of NCDs increased by three times (i.e., aPR 3, 95% CI = 1.1, 1.5, and 6.0). CONCLUSION AND RECOMMENDATIONS: PEN Plus training improved the knowledge of healthcare workers at Kondoa Town Council District Hospital. Training is especially needed among nurses and those with a longer duration of work. Continuing education for human resources for health on the management of NCDs is highly recommended in this setting.

Expanding access to parasite-based malaria diagnosis through retail drug shops in Tanzania: evidence from a randomized trial and implications for treatment.

BACKGROUND: Tanzania has seen a reduction in the fraction of fevers caused by malaria, likely due in part to scale-up of control measures. While national guidelines require parasite-based diagnosis prior to treatment, it is estimated that more than half of suspected malaria treatment-seeking in Tanzania initiates in the private retail sector, where diagnosis by malaria rapid diagnostic test (RDT) or microscopy is illegal. This pilot study investigated whether the introduction of RDTs into Accredited Drug Dispensing Outlets (ADDOs) under realistic market conditions would improve case management practices. METHODS: Dispensers from ADDOs in two intervention districts in Tanzania were trained to stock and perform RDTs and monitored quarterly. Each district was assigned a different recommended retail price to evaluate the need for a subsidy. Malaria RDT and artemisinin-based combination therapy (ACT) uptake and availability were measured pre-intervention and 1 year post-intervention through structured surveys of ADDO owners and exiting customers in both intervention districts and one contiguous control district. Descriptive analysis and logistic regression were used to compare the three districts and identify predictive variables for testing. RESULTS AND DISCUSSION: A total of 310 dispensers from 262 ADDOs were trained to stock and perform RDTs. RDT availability in intervention ADDOs increased from 1% (n = 172) to 73% (n = 163) during the study; ACT medicines were available in 75% of 260 pre-intervention and 68% of 254 post-intervention ADDOs. Pre-treatment testing performed within the ADDO increased from 0 to 65% of suspected malaria patients who visited a shop (95% CI 60.8-69.6%) with no difference between intervention districts. Overall parasite-based diagnosis increased from 19 to 74% in intervention districts and from 3 to 18% in the control district. Prior knowledge of RDT availability (aOR = 1.9, p = 0.03) and RDT experience (aOR = 1.9, p = 0.01) were predictors for testing. Adherence data indicated that 75% of malaria positives received ACT, while 3% of negatives received ACT. CONCLUSIONS: Trained and supervised ADDO dispensers in rural Tanzania performed and sold RDTs under real market conditions to two-thirds of suspected malaria patients during this one-year pilot. These results support the hypothesis that introducing RDTs into regulated private retail sector settings can improve malaria testing and treatment practices without an RDT subsidy.

Pursuing health systems strengthening through disease-specific programme grants: experiences in Tanzania and Sierra Leone.

INTRODUCTION: Disease-specific 'vertical' programmes and health system strengthening (HSS) 'horizontal' programmes are not mutually exclusive; programmes may be implemented with the dual objectives of achieving both disease-specific and broader HSS outcomes. However, there remains an ongoing need for research into how dual objective programmes are operationalised for optimum results. METHODS: A qualitative study encompassing four grantee programmes from two partner countries, Tanzania and Sierra Leone, in the Comic Relief and GlaxoSmithKline 'Fighting Malaria, Improving Health' partnership. Purposive sampling maximised variation in terms of geographical location, programme aims and activities, grantee type and operational sector. Data were collected via semi-structured interviews. Data analysis was informed by a general inductive approach. RESULTS: 51 interviews were conducted across the four grantees. Grantee organisations structured and operated their respective projects in a manner generally supportive of HSS objectives. This was revealed through commonalities identified across the four grantee organisations in terms of their respective approach to achieving their HSS objectives, and experienced tensions in pursuit of these objectives. Commonalities included: (1) using short-term funding for long-term initiatives; (2) benefits of being embedded in the local health system; (3) donor flexibility to enable grantee responsiveness; (4) the need for modest expectations; and (5) the importance of micro-innovation. CONCLUSION: Health systems strengthening may be pursued through disease-specific programme grants; however, the respective practice of both the funder and grantee organisation appears to be a key influence on whether HSS will be realised as well as the overall extent of HSS possible.

Evaluation of near point-of-care viral load implementation in public health facilities across seven countries in sub-Saharan Africa.

INTRODUCTION: In many low- and middle-income countries, HIV viral load (VL) testing occurs at centralized laboratories and time-to-result-delivery is lengthy, preventing timely monitoring of HIV treatment adherence. Near point-of-care (POC) devices, which are placed within health facility laboratories rather than clinics themselves (i.e. "true" POC), can offer VL in conjunction with centralized laboratories to expedite clinical decision making and improve outcomes, especially for patients at high risk of treatment failure. We assessed impacts of near-POC VL testing on result receipt and clinical action in public sector programmes in Cameroon, Democratic Republic of Congo, Kenya, Malawi, Senegal, Tanzania and Zimbabwe. METHODS: Routine health data were collected retrospectively after introducing near-POC VL testing at 57 public sector health facilities (2017 to 2019, country-dependent). Where possible, key indicators were compared to data from patients receiving centralized laboratory testing using hazard ratios and the Somers' D test. RESULTS: Data were collected from 6795 tests conducted on near-POC and 17614 tests on centralized laboratory-based platforms. Thirty-one percent (2062/6694) of near-POC tests were conducted for high-risk populations: pregnant and breastfeeding women, children and those with suspected failure. Compared to conventional testing, near-POC improved the median time from sample collection to return of results to patient [six vs. sixty-eight days, effect size: -32.2%; 95% CI: -41.0% to -23.4%] and to clinical action for individuals with an elevated HIV VL [three vs. fourty-nine days, effect size: -35.4%; 95% CI: -46.0% to -24.8%]. Near-POC VL results were two times more likely to be returned to the patient within 90 days compared to centralized tests [50% (1781/3594) vs. 27% (4172/15271); aHR: 2.22, 95% CI: 2.05 to 2.39]. Thirty-seven percent (340/925) of patients with an elevated near-POC HIV VL result had documented clinical follow-up actions within 30 days compared to 7% (167/2276) for centralized testing. CONCLUSIONS: Near-POC VL testing enabled rapid test result delivery for high-risk populations and led to significant improvements in the timeliness of patient result receipt compared to centralized testing. While there was some improvement in time-to-clinical action with near-POC VL testing, major gaps remained. Strengthening of systems supporting the utilization of results for patient management are needed to truly capitalize on the benefits of decentralized testing.

Averting Maternal Death and Disability in an Urban Network of Care in Dar es Salaam, Tanzania: A Descriptive Case Study.

The non-governmental organization Comprehensive Community Based Rehabilitation in Tanzania (CCBRT) developed a multi-facility maternal and neonatal Network of Care (NOC) among 22 government hospitals and catchment facilities operating across Dar es Salaam. While facility delivery rates were above 90% in the Dar es Salaam region, the quality of services was substandard, leading to an excess of preventable maternal and neonatal morbidity and mortality. In partnership with the Dar es Salaam regional health authorities CCBRT developed a plan to improve the quality of service delivery at childbirth by through a system strengthening approach, capacitating lower-level facilities to provide routine care during pregnancy and uncomplicated deliveries, as well as improving care at secondary level referral hospitals and developing an inter-connected strengthened referral system. The Regional-CCBRT partnership implemented interventions across the continuum of care that included clinical training in basic and comprehensive emergency obstetric care, investments in infrastructure, and a rigorous maternal and perinatal death audit and follow-up program. Routine data generated were reflected upon at quarterly quality improvement meetings to follow up on problems identified. The government has initiated the replication of the model. This descriptive case study uses the four domains of the Networks of Care framework to document the wide-ranging efforts made to build and maintain the CCBRT Network of Care in order to solve for specific challenges in maternal and neonatal health service delivery in the urban context of the Dar es Salaam region.
