Abstract
Modified directly observed therapy (mDOT), in which a portion of total doses of a medication regime is ingested under supervision, has demonstrated efficacy as an intervention to assist patients in maintaining adherence to complicated antiretroviral therapy (ART). Although findings are favorable, existing efficacy studies fail to provide sufficient detail to guide others who wish to implement mDOT interventions. The aim of this article is to provide a primer for practitioners and researchers who wish to implement mDOT interventions. Drawing on the experience of 10 federally funded research projects, we provide guidance on critical questions for program implementation, including: who should be targeted, length/duration/content/location/tapering of sessions, staffing, incentives, and approaches to data collection. In addition, guidance on staff training and minimum requirements for mDOT interventions is offered along with real-world examples of mDOT interventions. mDOT is feasible and easily adapted to many settings and target populations. Interventions should match the specific needs of the target population and setting and be flexible in terms of design and delivery. mDOT should be considered among the spectrum of adherence interventions.
