Abstract:Background Intravenous unfractionated heparin (IV UFH) has a narrow therapeutic index and poses a high risk of bleeding. Objective To determine the impact of pharmacy monitoring and intervention on adherence to and appropriate implementation of IV UFH protocol. Setting A 438 bed hospital specializing in cardiac services. Methods This is a retrospective chart review study. Pre-pharmacy intervention data were collected from November 2013 to January 2014 and compared to post-pharmacy intervention data obtained be… Show more
“…Previous studies have supported favorable outcomes in the management of UFH based on pharmacist-driven management. [18][19][20] Although these pharmacist interventions were associated with positive outcomes on UFH management at the time of infusion initiation, the present study differs from current literature because of its focus on pharmacist intervention in patients with supratherapeutic aPTT values where aPTT may not have been the most optimal monitoring tool. Previous studies evaluated time to therapeutic range to evaluate pharmacist intervention at the time of UFH initiation.…”
Background: Unfractionated heparin (UFH) infusions are commonly managed with nurse-driven nomograms titrated to activated partial thromboplastin time (aPTT). In some patients, anti-Xa values may be more appropriate measures of anticoagulation. At the present institution, an update to the nurse-driven aPTT nomogram requires pharmacist notification and clinical assessment for critically supratherapeutic aPTT results. Objective: The purpose of this study was to evaluate the efficacy and safety of the nomogram update. Methods: A single-center, retrospective, pre-post analysis was conducted in patients treated with UFH who experienced a critical aPTT during the 6 months preceding and following the nomogram update. Patients with erroneous critical aPTT results were excluded. The primary endpoint was the time in therapeutic range (Rosendaal method) from the first critical aPTT until UFH discontinuation. Secondary endpoints included the proportion of patients transitioned to anti-Xa monitoring and the incidence of Bleeding Academic Research Consortium (BARC) 2, 3, 5 bleeding. Data were analyzed by the χ2 test. The study was institutional review board approved. Results: Of 277 UFH infusions, 142 belonged to the pre-implementation group and 135 to the post-implementation group. Baseline aPTTs were similar between the 2 groups. Time in therapeutic range was 58.1% versus 62.4% of between groups ( P = .467). UFH was transitioned to pharmacist-driven anti-Xa monitoring in 16.2% versus 40.3% of patients ( P < .001). BARC 2, 3, 5 bleeding occurred in 23.2% versus 13.4% of patients ( P < .001). Conclusions: Application of these data suggest improved safety and efficacy outcomes with directed pharmacist management of UFH in patients with critically elevated aPTTs.

Purpose:
This study assessed the impact of process standard work, a quality improvement tool, on staff adherence to nurse-driven unfractionated heparin (UFH) protocols in adult patients at a community teaching hospital.
Methods:
This was a retrospective quality improvement project, and statistical analysis was performed by a senior research specialist at the facility.
Results:
In total, 109 venous thromboembolism or cardiac UFH anticoagulant protocols were included in the final analysis, accounting for 445 activated partial thromboplastin time results.
Conclusion:
There was no change in adherence to a nurse-driven UFH protocol among adult patients after the implementation of process standard work.
