Background  Statin administration early in ischemic stroke may influence outcomes. Our aim was to determine the clinical impact of increasing statin administration early in ischemic stroke hospitalization.    Methods and Results  This is a retrospective analysis of a multicenter electronic medical record ( EMR ) intervention to increase early statin administration in ischemic stroke across all 20 hospitals of an integrated healthcare delivery system. A stroke  EMR  order set was modified from an “opt‐in” to “opt‐out” mode of statin ordering. Outcomes were mortality by 90 days, discharge disposition, and increase in stroke severity. We examined the relationship between intervention and outcome using autoregressive integrated moving average (ARIMA) time‐series modeling. The  EMR  intervention increased both overall in‐hospital statin administration (from 87.2% to 90.7%,  P <0.001) and early statin administration (from 16.9% to 26.3%,  P <0.001). ARIMA models showed a small increase in the rate of survival (difference in probability [ P  diff ]=0.02,  P =0.016) and discharge to home or rehabilitation facility ( P  diff =0.04,  P =0.034) associated with the intervention. The increase in statin administration <8 hours was associated with much larger increases in survival ( P  diff =0.17,  P =0.033) and rate of discharge to home or rehabilitation ( P  diff =0.29,  P =0.011), as well as a decreased rate of neurological deterioration in‐hospital ( P  diff =−0.14,  P =0.026).    Conclusions  A simple  EMR  change increased early statin administration in ischemic stroke and was associated with improved clinical outcomes. This is, to our knowledge, the first  EMR  intervention study to show that a modification of an electronic order set resulted in improved clinical outcomes.
