Evaluating Adherence to Guideline-Directed Infection Management Pre- and Postimplementation of an Electronic Order Set.

BACKGROUND

After publication of the infection (CDI) guidelines by the Infectious Disease Society of America (IDSA) in early 2018, we identified that many prescribers at our institution continued to practice using the older guidelines.

OBJECTIVE

This study aimed to determine whether the implementation of an electronic order set for CDI would increase prescriber compliance to current IDSA recommendations for CDI management.

METHODS

This was a single-center, prospective cohort study of adult inpatients with a confirmed CDI. The study was conducted between March 1, 2018, and April 1, 2019. Patients were stratified into a preintervention and postintervention group before and after order set implementation. The primary outcome was a composite of appropriate CDI therapy selection and discontinuation of nonessential antimicrobials and acid-suppressive agents. The secondary outcome evaluated appropriate CDI therapy medications prescribed at hospital discharge.

RESULTS

Of the 149 patients included in this study, 96 were included in a preintervention group and 53 included in a postintervention group. The primary outcome was met in 45% of patients in the preintervention group and 66% of patients in the postintervention group ( = .01). The secondary outcome occurred in 86% of patients in the preintervention group and 100% of patients in the postintervention group ( = .02).

CONCLUSION

Implementation of a CDI electronic order set and alert bundle was associated with enhanced prescriber adherence to guideline-directed therapy. Our results suggest that order sets not only improve inpatient compliance to guidelines but may also improve medication-related adherence to guideline recommendations upon discharge.
