Objective
To study the effect of electronic health record (EHR) implementation on the operational metrics of a diverse group of community emergency departments (ED).
Methods
We performed a retrospective before/after analysis of 23 EDs from a single management group that experienced EHR implementation, defined as the date of implementation of electronic clinical documentation in the ED. We obtained electronic data for 4 length-of-stay (LOS) measures (arrival-to-provider, admitted, discharged and overall LOS) and 4 measures of operational characteristics (left-prior-to–treatment-complete, significant returns, overall patient satisfaction and provider efficiency). We compared the 6-month “baseline” period immediately prior to implementation with a “steady-state” period commencing 6 months after implementation for all 8 metrics.
Results
For the LOS measures, there were no differences in the arrival-to-provider interval (difference of −0.02 hours, 95% CI of difference −0.12, 0.08), admitted LOS (difference of 0.10 hours, 95% CI of difference −0.17, 0.37), discharged LOS (difference of 0.07 hours, 95% CI of difference −0.07, 0.22) and overall LOS (difference of 0.11 hours, −0.04, 0.27). For operational characteristics, there were no differences in the percentage who left-prior-to-treatment-complete (difference of 0.24%, 95% CI of difference −0.47%, 0.95%), significant returns (difference of −0.04%, 95% CI of difference −0.48%,0.39%), overall percentile patient satisfaction (difference of −0.02%, 95% CI of difference −2.35%, 2.30%) and provider efficiency (difference of −0.05 patients/hour, 95% CI of difference −0.11,0.02).
Conclusions
There is no meaningful difference in 8 measures of operational performance for community EDs experience EHR implementation between a baseline and steady state period.
