Attaining 95-95-95 through Implementation Science: 15 Years of Insights and Best Practices from the Walter Reed Army Institute of Research's Implementation of the U.S. President's Emergency Plan for AIDS Relief.

ABSTRACT: The Walter Reed Army Institute of Research (WRAIR) supports more than 350,000 people on lifesaving HIV treatment in Kenya, Nigeria, Tanzania, and Uganda through funding from the U.S. President's Emergency Plan for AIDS Relief (PEPFAR). Here, we review and synthesize the range of impacts WRAIR's implementation science portfolio has had on PEPFAR service delivery for military and civilian populations since 2003. We also explore how investments in implementation science create institutional synergies within the U.S. Department of Defense, contributing to broad global health engagements and improving health outcomes for populations served. Finally, we discuss WRAIR's contributions to PEPFAR priorities through use of data to drive and improve programming in real time in the era of HIV epidemic control and public health messaging that includes prevention, the 95-95-95 goals, and comorbidities.

Project description:The US budget for global health funding, which was by far the largest of similar funding in the world, increased from US $1.3 billion in 2001 to more than US $10 billion in recent years. More than 54% of this funding was allocated to the Global Fund to Fight HIV/AIDS through the US President's Emergency Plan for AIDS Relief (PEPFAR) in Africa. However, recent studies indicate contradictory results regarding the effectiveness of PEPFAR. One by Bendavid, Holmes, Bhattacharya, and Miller shows positive effects of PEPFAR in reducing adult mortality in Africa, while another by Duber, Coates, Szekeras, Kaji, and Lewis finds that there are no significant differences in reducing adult mortality in countries that received PEPFAR funding vs countries that did not. Due to their potential impact on policy decisions regarding critical global health funding, we wanted to assess why the results are discrepant. To do this, we replicated the Bendavid study. The replication provides verification that the study replicable and that the analytic choices of the authors are robust to different assumptions or restrictions. This allows us to assess the different choices and data available to the two research groups and draw some conclusions about why the results may be different. Then, focusing on two of the prominently discrepant studies, i.e., the Bendavid study (1998-2008) and the Duber study (2000-2006), we establish why the two studies are in disagreement. We apply appropriate individual-level and country-level analytical methodology as used by Bendavid over the analytical time period used for the Duber study (2000-2006), which originally focused on nationally aggregated data and differed in some key focus countries. For our first objective, we replicated the original Bendavid study findings and our findings support their conclusion that between 1998-2008 all-cause mortality decreased significantly more (OR = 0.84, CI, 0.72-0.99) in countries that implemented PEPFAR. For our second objective (Bendavid's data and methodology applied to Duber's study period), we found reduction in all cause adult mortality to be borderline insignificant (OR = 0.87 CI, 0.75-1.01, p = 0.06), most possibly reflecting the abbreviated fewer number of events and sample size over a shorter period. Therefore, our overall analyses are consistent with the conclusion of positive impact of the PEPFAR program in reducing adult mortality. We believe that the discrepancy observed in the original studies mainly a reflection of shortcomings in the analytical approach necessitated by the Duber study's nationally aggregated dataset or "may reflect a lack of data quality" in the Duber study (Duber, et al. 2010).

Project description: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.
