RESUMO
As part of the Choosing Wisely Campaign, the Society of Hospital Medicine identified reducing inappropriate use of acid-suppressive medication for stress ulcer prophylaxis as 1 of 5 key opportunities to improve the value of care for hospitalized patients. We designed a computerized clinical decision support intervention to reduce use of acid-suppressive medication for stress ulcer prophylaxis in hospitalized patients outside of the intensive care unit at an academic medical center. Using quasiexperimental interrupted time series analysis, we found that the decision support intervention resulted in a significant reduction in use of acid-suppressive medication with stress ulcer prophylaxis selected as the only indication, a nonsignificant reduction in overall use, and no change in use on discharge. We found low rates of use of acid-suppressive medication for the purpose of stress ulcer prophylaxis even before the intervention, and continuing preadmission medication was the most commonly selected indication throughout the study. Our results suggest that attention should be focused on both the inpatient and outpatient settings when designing future initiatives to improve the appropriateness of acid-suppressive medication use.

BACKGROUND: Potentially inappropriate medication (PIM) use in hospitalized older patients is common. Our objective was to determine whether a computerized provider order entry (CPOE) drug warning system can decrease orders for PIMs in hospitalized older patients. METHODS: We used a prospective before-and-after design among patients 65 years or older admitted to a large, urban academic medical center in Boston, Massachusetts, from June 1, 2004, through November 29, 2004 (for patients admitted before the warning system was added), and from March 17, 2005, through August 30, 2008 (patients admitted after the warning system was added). We instituted a medication-specific warning system within CPOE that alerted ordering providers at the point of care when ordering a PIM and that advised alternative medication or dose reduction. The main outcome measure was the rate of orders for PIMs before and after the warning system was deployed. RESULTS: The mean (SE) rate of ordering medications that were not recommended dropped from 11.56 (0.36) to 9.94 (0.12) orders per day after the implementation of a CPOE warning system (difference, 1.62 [0.33]; P<.001), with no evidence that the effect waned over time. There were no appreciable changes in the rate of ordering medications for which only dose reduction was recommended or that were not targeted after CPOE implementation. These effects persisted in autoregressive models that accounted for secular trends and season (P<.001). CONCLUSION: Specific alerts embedded into a CPOE system, used in patients 65 years or older, can decrease the number of orders of PIMs quickly and specifically.
