Impact of Clinical, Unit-Specific Guidelines on Dornase Alfa Use in Critically Ill Pediatric Patients Without Cystic Fibrosis

摘要

Purpose: The purpose of this study was to evaluate the impact of the implementation of pharmacist-guided, unit-specific dornase alfa utilization guidelines for patients without cystic fibrosis in an academic medical institution. The study reviewed the prescribing patterns in the institution's pediatric intensive care unit (PICU) and pediatric cardiac intensive care unit (PCICU) before and after the implementation of these guidelines. The primary objective of this study was to determine the effects of the guidelines on the number of dornase alfa doses prescribed in critically ill pediatric patients without cystic fibrosis. We also evaluated the pharmacoeconomic effect of the guidelines and the impact on clinical outcomes in these critically ill patients. Methods: This study was a single-center, retrospective evaluation of the implementation of pharmacist-guided, unit-specific dornase alfa guidelines. The guidelines were piloted on November 1, 2015. Pre-guideline implementation data were collected from February 1, 2015 to October 31, 2015. Post-guideline implementation data were collected from December 1, 2016 to August 31, 2016. We included patients admitted to the PICU and PCICU who had received at least 1 dose of dornase alfa and did not have a medical history or suspicion of cystic fibrosis. Results: During the pre-guideline data collection period, 1067 doses of dornase alfa were administered, and following guideline implementation, 239 doses were administered. The average total admission length of stay for patients admitted to the PICU or PCICU before guideline implementation and after implementation was 16.22 and 13.14 days, respectively (P = .042). Conclusions: The implementation of pharmacist-guided, unit-specific dornase alfa guidelines within the PICU and PCICU resulted in a 77.6% reduction in the use of dornase alfa among these units. The implementation of these guidelines led to a cost reduction of approximately US $87 707.76 over a 9-month period for the health system. During the study, the length of stay for patients admitted to the PICU and PCICU did not increase, indicating that the reduction in use of dornase alfa did not negatively affect the overall hospital length of stay for patients.
