BackgroundIncreasing prescription overdose deaths have demonstrated the need for safer emergency department (ED) prescribing practices for patients who are frequent ED users.ObjectivesWe hypothesized that the care of frequent ED users would improve using a citywide care coordination program combined with an ED care coordination information system, as measured by fewer ED visits by and decreased controlled substance prescribing to these patients.MethodsWe conducted a multisite randomized controlled trial (RCT) across all EDs in a metropolitan area; 165 patients with the most ED visits for complaints of pain were randomized. For the treatment arm, drivers of ED use were identified by medical record review. Patients and their primary care providers were contacted by phone. Each patient was discussed at a community multidisciplinary meeting where recommendations for ED care were formed. The ED care recommendations were stored in an ED information exchange system that faxed them to the treating ED provider when the patient presented to the ED. The control arm was subjected to treatment as usual.ResultsThe intervention arm experienced a 34% decrease (incident rate ratios = 0.66, p < 0.001; 95% confidence interval 0.57-0.78) in ED visits and an 80% decrease (odds ratio = 0.21, p = 0.001) in the odds of receiving an opioid prescription from the ED relative to the control group. Declines of 43.7%, 53.1%, 52.9%, and 53.1% were observed in the treatment group for morphine milligram equivalents, controlled substance pills, prescriptions, and prescribers, respectively.ConclusionThis RCT showed the effectiveness of a citywide ED care coordination program in reducing ED visits and controlled substance prescribing.Copyright © 2016 The Author(s).
