Monitoring Pharmacy and Test Kit Stocks in Rural Mozambique: U.S. President's Emergency Plan for AIDS Relief Surveillance to Help Prevent Ministry of Health Shortages.

Support of human immunodeficiency virus (HIV) and tuberculosis (TB) testing and treatment supported by President's Emergency Plan for AIDS Relief (PEPFAR) in Africa requires immense quantities of tests and medications. We sought to use central pharmacy supply data of Mozambique's rural Zambézia Province (2017 population ≈5.11 million persons; ≈12.6% adult HIV prevalence in 2016) to examine shortages, stockouts, and trends in availability. Using stock surveillance for 60 weeks in 2014-2015, we assessed availability of 36 medications [4 classes: adult antiretroviral (ARV) medications, pediatric ARVs, anti-TB medications, and antibiotics] and diagnostic test kits (2 rapid tests for HIV; 1 each for malaria and syphilis). We contrasted these to 2018-2019 data. We modeled pharmacy data using ordinal logistic regression, characterizing weekly product availability in four categories: good, adequate, shortage, or complete stockout. We found 166 (7.7%) stockouts and 150 (6.9%) shortages among 2,160 weekly records. Earlier calendar time was associated with reduced medication supplies (p < .001). Certain medication/test kit classes were associated with reduced supply (p < .001). We found an interaction between time and medication class on the odds of reduced supply (p < .001). Pediatric ARVs had a 17.4 (95% confidence interval: 8.8-34.4) times higher odds of reduced medication supply compared with adult ARVs at study midpoint. Trends comparing the first and last weeks showed adult ARVs having 67% and pediatric having 71% lower odds of reduced supplies. Only adult ARV shortages improved amid growing demand. Data from 2018 to 2019 suggest continuing inventory management challenges. Monitoring of drug (especially pediatric) and test kit shortages is vital to ensure quality improvement to guarantee adequate supplies to enable patients and care providers to achieve sustained viral suppression. A central Mozambican drug repository in the nation's second largest Province continues to experience drug and rapid test kit stockouts.

HIV Rapid Diagnostic Test Inventories in Zambézia Province, Mozambique: A Tale of 2 Test Kits.

BACKGROUND: The first pillar of the UNAIDS 90-90-90 goal seeks to accurately identify persons living with HIV (PLHIV), a process that is predicated on facilities having the necessary HIV tests available to perform the task. In many rural settings, the identification of PLHIV is accomplished through a two-step process involving the sequential use of 2 separate rapid diagnostic tests (RDTs). Inadequate inventory of either test has ramifications for the success of HIV-related programs. The purpose of this study was to evaluate the inventory levels of HIV RDT kits at specific healthcare facilities in Zambézia province, Mozambique. METHODS: Using facility-level pharmacy stock surveillance data from October 2015 through September 2016, we assessed the inventory levels of HIV RDTs at 75 health facilities in 8 districts within Zambézia province, Mozambique. Using programmatically established categories (good, sufficient, threatened, or stockout), defined in conjunction with the provincial health authorities, descriptive statistics were performed to determine inventory control of HIV RDTs at the district and health facility levels. Monthly proportions of adequate (good + sufficient) inventory were calculated for each district to identify inventory trends over the evaluation period. To assess whether the proportion of inadequate stocks differed between RDT, a mixed-effects logistic regression was conducted, with inadequate inventory status as the outcome of interest. RESULTS: When viewed as a whole, the inventory of each test kit was reported as being at adequate levels more than 89% of the time across the 75 facilities. However, disaggregated analysis revealed significant variability in the inventory levels of HIV RDTs at the district level. Specifically, the districts of Inhassunge, Namacurra, and Pebane reported inadequate inventory levels (threatened + stockout), of one or both test kits, for more than 10% of the study period. In addition, a disparity between inventory levels of each test kit was identified, with the odds of reporting inadequate inventory levels of the confirmatory test (Uni-Gold™) being approximately 1.8-fold greater than the initial test (Determine™) (odds ratio: 1.82, 95% CI: 1.40-2.38). CONCLUSION: As Test and Treat programs evolve, a significant emphasis should be placed on the "test" component of the strategy, beginning with assurances that health facilities have the adequate inventory of RDT necessary to meet the needs of their community. As national policy-makers rely predominantly on data from the upstream arm of the supply chain, it is unlikely the disparity between inventory levels of HIV RDTs identified at individual districts and specific health facilities would have been recognized. Moving forward, our findings point to a need for (1) renewed efforts reinforcing appropriate downstream forecasting of essential medicines and diagnostic tests in general and for Uni-Gold™ test kits specifically, and (2) simple metrics that may be routinely collected at all health facilities and which may then easily and quickly flow upstream so that policy-makers may optimally allocate resources.
