Stakeholder perspectives on interventions to improve HIV pre-exposure prophylaxis uptake and continuation in Lesotho: A participant-ranked preferences study

Low uptake and high discontinuation remain major obstacles to realizing the potential of Pre-Exposure Prophylaxis (PrEP) in changing the trajectory of the HIV epidemic. We conducted a card sorting and ranking exercise with 155 local stakeholders to determine their views on the most important barriers and most promising interventions to achieving high PrEP coverage. Stakeholders were a purposive sample of PrEP policymakers and implementing partners (n = 7), healthcare providers (n = 51), and end-users (n = 97). End-users included adults who were currently using PrEP (n = 55), formerly using PrEP (n = 36), and those who were offered PrEP but declined (n = 6). Participants sorted pre-selected interventions and barriers to PrEP coverage into three piles–most, somewhat, and least important. Participants then ranked interventions and barriers in the “most important” piles in ascending order of significance. Ranked preferences were analyzed as voting data to identify the smallest set of candidates for which each candidate in the set would win in a two-candidate election against any candidate outside the set. Participants viewed a lack of PrEP awareness as the most important barrier to PrEP uptake for women, and a fear of HIV testing for men. Community-based HIV testing was ranked as the most promising intervention to improve PrEP uptake for both men and women. Perceived or experienced stigma was seen as an important barrier for PrEP continuation for both men and women, with an additional important barrier for men being daily activities that compete with the time needed to take a daily pill. Adherence counseling and multi-month PrEP prescriptions were seen as the most promising interventions to improve PrEP continuation. Our findings suggest community-based activities that generate PrEP demand (community-based HIV testing and mass media campaigns), reinforced with facility-based follow-up (counseling and multi-month prescription) could be promising interventions for PrEP programs that are aimed at the general adult population.
