ABSTRACT
OBJECTIVE: To examine changes in persistent emergency department (ED) use by adult frequent ED (FED) users over time comparing prepandemic versus peripandemic periods, and to identify distinct characteristics of individuals who remained FED users over time during the pandemic versus the prepandemic era.
METHODS: We conducted a retrospective, secondary, longitudinal analysis in Texas, following 2 cohorts of ED users over 36 months (cohort 1: March 2017-February 2020; cohort 2: March 2019-February 2022). The main outcomes were whether a baseline FED (≥9 ED visits/12 mo) user remained a FED user persistently over the next 24 months and whether they were persistent FED users prepandemic or peripandemic. Multivariable regressions estimated changes in persistent FED use across cohorts and assessed differences between individuals who remained persistent FED users during the pandemic compared with the prepandemic period.
SETTING: All-payer Texas Hospital ED Research Data File from 2016 to 2022.
RESULTS: About 1 million individuals had at least one ED visit in the baseline years, totaling 4.6 million visits. Overall, FED users accounted for 8% of all ED users but over 40% of visits. Although more than half of FED users at baseline exhibited persistent FED use over the next 24 months, there was a 7% decline in the proportion of return FED users after the onset of COVID-19 which was statistically significant (AOR=0.82; 95% CI=0.80-0.84), and this effect was more pronounced when patients with any COVID-19-related ED visit during the study period were excluded (AOR=0.10; 95% CI=0.09-0.11). Individuals aged 45 years or older, those with congestive heart failure and diabetes with complications, and those with public insurance (when COVID-19-related visits were excluded) had higher odds of remaining persistent FED users during the pandemic.
CONCLUSIONS: Many FED users will seek ED care for multiple years, given their medical complexity. Future research should identify heterogeneous subgroups among persistent FED users to tailor interventions towards their needs.
