BackgroundWhile warfarin is the most commonly prescribed medication to prevent thromboembolic disorders, the risk of adverse drug reactions (ADR) poses a serious concern. This prospective study evaluated how primary care providers (PCP) and cardiologists at our Institution managed patients treated with warfarin with the goal of decreasing the number of warfarin ADRs.MethodsA multidisciplinary anticoagulation task force was established at our Institution in 2014 to standardize warfarin monitoring and management. Between 2013 and 2017, we analyzed patients who were prescribed warfarin by their PCP or cardiologist upon hospital discharge and in the ambulatory setting to determine the international normalized ratio (INR) within 5, 10, and 30 days after discharge, time in therapeutic range (TTR), number of severe warfarin ADRs, and total and average cost reduction of all severe warfarin ADRs to determine whether there was an organizational cost savings following the implementation of standardized warfarin care.ResultsThe warfarin ADR rate significantly decreased over the 5-year period, from 3.8 to 0.98% (p < 0.0001). The proportion of warfarin prescriptions out of all anticoagulants significantly decreased, from 72.2 to 42.1% (p < 0.001). The proportion of individuals who received an INR at 5, 10, and 30 days after hospital discharge compared to the total number of patients prescribed warfarin significantly increased (p < 0.001). The total cost of severe warfarin ADRs decreased by 57.6% between 2013 and 2017.ConclusionsThis study serves as a model to reduce the number of severe warfarin ADRs by the following tactics: (1) educating PCPs and cardiologists about evidence-based guidelines for warfarin management, (2) increasing the use of our Institution’s electronic warfarin module, and (3) enhancing patient compliance with obtaining INR.

Objective: Prescription opioid misuse represents a social and economic challenge in the United States. We evaluated Schedule II opioid prescribing practices by primary care providers (PCPs), orthopedic and general surgeons, and pain management specialists.Design: Prospective evaluation of prescribing practices of PCPs, orthopedic and general surgeons, and pain management specialists over 5 years (October 1, 2014-September 30, 2019) in an outpatient setting.Methods: An analysis of Schedule II opioid prescribing following the implementation of federal and state guidelines and evidence-based standards at our institution. Results: There were significantly more PCPs, orthopedic and general surgeons, and pain management specialists with a significantly increased number who prescribed Schedule II opioids, whereas there was a simultaneous significant decline in the average number of Schedule II opioid prescriptions per provider, Schedule II opioid pills prescribed per provider, and Schedule II opioid pills prescribed per patient by providers. The average number of Schedule II opioid prescriptions with a quantity 90 and Opana/Oxycontin prescriptions per PCP, orthopedic surgeon, and pain management specialist significantly decreased. The total morphine milligram equivalent (MME)/day of Schedule II opioids ordered by PCPs, orthopedic and general surgeons, and pain management specialists significantly declined. The ages of the providers remained consistent throughout the study. Conclusions: This study reports the implementation of federal and state regulations and institutional evidence-based guidelines into primary care and medical specialty practices to reduce the number of Schedule II opioids prescribed. Further research is warranted to determine alternative therapies to Schedule II opioids that may alleviate a patient’s pain without initiating or exacerbating a potentially lethal opioid addiction.
