Background: For patients on continuous IV unfractionated heparin (UFH), failing to achieve a therapeutic aPTT by 24 hours can be associated with increased morbidity. A pharmacy clinical surveillance system (PCSS) subtherapeutic aPTT alert was implemented at our institution to improve achievement of therapeutic aPTT goals by 24 hours. Objective: The primary objective was the time to achieve the minimum goal aPTT before and after the alert implementation. The secondary objectives were to examine the percentage of patients who achieved the minimum goal aPTT by 24 hours and the number of dose changes to achieve the minimum goal aPTT. Methods: A single-center retrospective study was conducted to include all adult inpatients receiving a continuous UFH infusion during a 3-month period prior to the implementation of a subtherapeutic aPTT alert and a 3-month period after implementation. Results: 317 patients were included in the analysis. The average time to achieve the minimum goal aPTT was 21.8 hours prior to alert implementation and 15.4 hours after implementation (p = .002). The percent of patients who achieved the minimum goal aPTT by 24 hours was 65.7% prior to alert implementation and 82.4% after implementation (p = .035). The average number of dose changes necessary to achieve aPTT value to the minimum goal aPTT prior to alert implementation was 1.67 and 1. 98 after implementation (p = .68). Conclusion: This analysis showed that implementation of a PCSS subtherapeutic aPTT alert for patients on continuous UFH infusions may ensure patients reach goal aPTT faster and facilitate a higher percent of patients who achieve the minimum goal aPTT by 24 hours.
