This document discusses the development of a compendium of effective structural HIV prevention interventions. It describes the process of establishing expert criteria for inclusion, selecting 18 interventions, and preparing detailed entries on the rationale, implementation, evaluation and lessons of each. The interventions addressed policies/laws, resource provision, and social marketing. Key themes were emerging from community needs, evolving implementation, and the difficulty of evaluating complex structural interventions. The compendium aims to facilitate replication and adaptation of evidence-based structural approaches.
