Provider preferences for delivery of HIV care coordination services: results from a discrete choice experiment
Introduction The PROMISE study was launched in 2018 to assess and document the implementation of changes to an existing HIV Care Coordination Program (CCP) designed to address persistent disparities in care and treatment engagement among persons with HIV in New York City. We evaluated provider endorsement of features of the CCP to identify opportunities for improvement. Methods We used a discrete choice experiment (DCE) to measure provider endorsement of four CCP attributes, including: a) how CCP helps with medication adherence, b) how CCP helps with primary care appointments, c) how CCP helps with issues other than primary care, and d) where CCP visits take place (visit location). Each attribute had three to four levels. Our primary outcomes were relative importance and part-worth utilities, measures of preference for the levels of the four CCP program attributes. Results Visit location (28.6%) had the highest relative importance, followed by how staff help with ART adherence (24.3%), how staff help with issues other than primary care (24.2%), and how staff help with primary care appointments (22.9%). Within each of the above attributes, respectively, the levels with the highest part-worth utilities were home visits 60 minutes from the program or agency (19.9 utiles, 95% CI 10.7-29.0), directly observed therapy (26.1 utiles, 95% CI 19.1-33.1), help with non-HIV specialty medical care (26.5 utiles, 95% CI 21.5-31.6), and reminding clients about and accompanying them to primary care appointments (20.8 utiles, 95% CI 15.6-26.0). Conclusions Ongoing CCP refinements should account for how best to support and evaluate the intensive CCP components endorsed by providers in this study.
