Healthcare information technology interventions to improve cardiovascular and XXXX medication adherence.

@entity1 @entity65 @entity6
OBJECTIVE: To determine the efficacy of healthcare information technology (HIT) interventions in improving adherence. STUDY DESIGN: Systematic search of randomized controlled trials of HIT interventions to improve medication adherence in @entity65 or @entity6 . METHODS: Interventions were classified as 1-way @entity1 reminder systems, 2-way interactive systems, and systems to enhance @entity1 -provider interaction. Studies were subclassified into those with and without real-time provider feedback. Cohen's d effect sizes were calculated to assess each intervention's magnitude of effectiveness. RESULTS: We identified 7190 articles, only 13 of which met inclusion criteria. The majority of included studies (54%, 7 studies) showed a very small ES. The effect size was small in 15%, large in 8%, and was not amenable to calculation in the remainder. Reminder systems were consistently effective, showing the largest effect sizes in this review. Education/counseling HIT systems were less successful, as was the addition of realtime adherence feedback to healthcare providers. Interactive systems were rudimentary and not integrated into electronic health records; they exhibited very small effect sizes. Studies aiming to improve @entity1 -provider communication also had very small effect sizes. CONCLUSIONS: There is a paucity of data about HIT's efficacy in improving adherence to medications for @entity65 and @entity6 , although simple @entity1 reminder systems appear effective. Future studies should focus on more sophisticated interactive interventions that expand the functionality and capabilities of HIT and better engage @entity1 in care.
