Article Summary

Objective: The authors of this study investigated the prevalence and impact of ED care fragmentation by characterizing the population of patients seeking care at multiple EDs and quantifying costs associated with this patient population.

 

Methods: This is a retrospective cohort study of insured patients who had one or more ED visit between 2010 and 2016. Outcomes investigated included number of EDs visited by each patient, the costs associated with this subset of patients, and factors associated with visiting multiple EDs.

 

Results: The study included 53,015,427 patients belonging to a single for-profit payer. Of this group, 8,651,716 patients had at least 1 ED visit and accounted for 16,390,676 ED visits resulting in  $26,102,831,740 in ED costs.

  • 20.5% of patients visited more than one ED but accounted for 41.4% of visits and 39.2% of costs

  • A small proportion (0.4%) of patients visited 5 or more EDs but accounted for 2.8% of ED visits and costs

  • Factors most strongly associated with visiting multiple EDs included age, living in the South, total years of enrollment and higher visit complexity

  • Diagnoses most strongly associated with visiting multiple EDs included alcohol and drug diagnoses and mental health disorders

 

Conclusion: A minority of patients seek care at multiple EDs but account for a significant cost burden. Characterization of this population suggests they represent higher complexity visits and are more likely to suffer from comorbid substance abuse and mental health conditions. The authors recommend further work to evaluate the impact of ED care fragmentation of care utilization and outcomes and recommend improving access to patient records to mitigate its effects.
