Abstract
OBJECTIVE: The objective of the study was to assess the impact of a computer physician order entry (CPOE) electronic order set on appropriate vancomycin dosing in the emergency department (ED). METHODS: We conducted a retrospective study examining ED dosing of vancomycin before and after the implementation of an electronic weight-based vancomycin order set. Preimplementation and postimplementation patient records were analyzed between the dates of June 1st and August 31st 2010 for the pre-CPOE group and January 1st to March 31st 2013 for the post-CPOE group. STATISTICAL ANALYSIS: χ(2) analysis, Fisher exact test, and t tests were performed with a 2-sided P value <.05 denoting statistical significance, where appropriate. RESULTS: A total of 597 patients were included in the study, with 220 in the pre-CPOE group and 377 in the post-CPOE group. The use of the electronic order set resulted in a 21.9% increase (P < .05) in appropriate dosing with 67.4% (254/377) of post-CPOE vancomycin doses considered appropriate vs 45.5% (100/220) in the pre-CPOE group. In critically ill patients, there was a 16.3% increase in appropriate dosing with 44.7% (38/85) in the post-CPOE group compared with 28.4% (19/67) in the pre-CPOE group. CONCLUSION: The implementation of an electronic order set increased the percentage of ED patients receiving appropriate initial vancomycin doses. The impact of increasing compliance to vancomycin guidelines is in accordance with stewardship principles that promote optimization of antimicrobial dosing based on individual patient characteristics. More studies are needed to assess the relationship between appropriate vancomycin loading doses in the ED and therapeutic outcomes.
