Abstract

Objective We sought to characterize the population of patients seeking care at multiple EDs and to quantify the proportion of all ED visits and costs accounted for by these patients. Methods We performed a retrospective, cohort study of de-identified insurance claims for privately insured patients with ≥ 1 ED visit between 2010 and 2016. We measured the number of EDs visited by each patient and determined the overall proportion of all ED visits and ED costs accounted for by patients who visit multiple EDs. We identified factors associated with visiting multiple EDs. Results 8,651,716 patients made 16,390,676 ED visits over the study period, accounting for $26,102,831,740 in ED costs. A significant minority (20.5%) of patients visited more than one ED over the study period. However, these patients accounted for a disproportionate amount of all ED visits (41.4%) and all ED costs (39.2%). A small proportion (0.4%) of patients visited 5 of more EDs but accounted for 2.8% of ED visits and costs. Among patients with two ED visits within 30-days, 32% were to different EDs. Having at least one ED visit for mental health or substance abuse related diagnosis was associated with increased odds of visiting multiple EDs. Conclusions A substantial minority of patients visit multiple EDs, but account for a disproportionate burden of overall ED utilization and costs. Future work should evaluate the impact of visiting multiple EDs on care utilization and outcomes and explore systems for…

How strong is the evidence?

Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 8,651,716 participants or records.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
