Interactional group discussion: results of a controlled trial using a behavioral intervention to reduce the use of injections in public health facilities.

Injections are commonly overused in Indonesia. More than 60% of patients attending public health facilities receive at least one injection, which increases clinical risk and has adverse economic impact. This study assesses the efficacy of an innovative behavioral intervention, the Interactional Group Discussion (IGD), for reducing the overuse of injections.
