Comparative effectiveness of care coordination interventions in the emergency department: a systematic review.

STUDY OBJECTIVE To conduct a systematic review on the effectiveness of emergency department (ED)-based care coordination interventions. METHODS We reviewed any randomized controlled trial or quasi-experimental study indexed in MEDLINE, CINAHL, Web of Science, Cochrane, or Scopus that evaluated the effectiveness of ED-based care coordination interventions. To be included, interventions had to incorporate information from previous visits, provide educational services on continuing care, provide post-ED treatment plans, or transfer information to continuing care providers. Studies had to quantify information transfer or report ED revisits, hospitalizations, or follow-up rates. Randomized controlled trial quality was assessed with the Jadad score. RESULTS Of 23 included articles, 14 were randomized controlled trials and 9 were quasi-experimental studies. Randomized controlled trial quality ranged from 2 to 3 on a 5-point scale. The majority of the studies (17) were conducted at a single center. Of nineteen studies that developed post-ED plans, 12 were effective in improving follow-up rates or reducing repeated ED visits. Four studies found paradoxically higher ED visit rates. Of 4 that used educational services for continuing care, 2 were effective. Of the 2 evaluating information transfer, 1 was effective. One study assessed incorporating information from other sites and found higher rates of information transfer, but utilization was not studied. CONCLUSION The majority of ED-based care coordination interventions focus on interfacing with outpatient providers, and about two thirds have been effective in increasing follow-up rates or reducing repeated ED utilization. Other types of interventions have shown similar effectiveness, but fewer have been studied.
