Analysis of the projected utility of dabigatran, rivaroxaban, and apixaban and their future impact on existing Hematology and Cardiology Anticoagulation Clinics at The Johns Hopkins Hospital.

The purpose of this study is to determine the percentage of patients in the Johns Hopkins Anticoagulation Clinics that are potential candidates for the new oral anticoagulants, dabigatran, rivaroxaban, and apixaban. A retrospective chart review was conducted of patients managed in the Johns Hopkins Cardiology and Hematology Anticoagulation Clinics between November 1, 2009 and October 31, 2010. Data elements collected include demographics, primary indication for anticoagulation, renal function, hepatic function, and concomitant medications. These factors were considered against product labeling guidelines and inclusion/exclusion criteria from clinical studies to derive candidacy status for each oral anticoagulant for each patient. Patients who met at least one caution or contraindication criteria were deemed "non-candidates"; potential dosage reductions of the new oral anticoagulants were not considered. Four hundred ninety-one patients participated in the study. Among participants, 63% would be dabigatran candidates, 62% rivaroxaban candidates, and 70% would be candidates for apixaban. Dabigatran use would be cautioned against in 34%, rivaroxaban in 18 %, and apixaban in 30%. Four percent had contraindications to dabigatran, whereas 21% had contraindications to rivaroxaban. More than 60% of patients in the Johns Hopkins Anticoagulation Clinics appear to be potential candidates for each of the new oral anticoagulants, assuming they are eventually approved for the same indications as warfarin. Many patients fell into the "cautioned" category, which demonstrates the complexity associated with selecting candidates for these new agents.

Development and implementation of a pharmacist-managed inpatient anticoagulation monitoring program.

PURPOSE. A stepwise approach to development and implementation of a program to standardize and increase pharmacists' involvement in anticoagulation therapy at a large academic medical center is described. SUMMARY. In response to the Joint Commission's national goal of improved patient safety in anticoagulation therapy, a work group of pharmacy administrators, educators, clinical specialists, and decentralized pharmacists at the hospital developed the structure for a comprehensive inpatient anticoagulation program (IAP); the work group also developed a list of required competencies, educational materials, assessment methods, and mechanisms for eliciting feedback from IAP pharmacists and other patient care staff. After completion of training that included structured case-review sessions, a one-on-one shadowing experience, and competency assessment, IAP pharmacists began reviewing clinical and laboratory data on patients receiving warfarin and low-molecular-weight heparins and providing recommendations to physicians, nurse practitioners, and other health care team members. Feedback from other clinicians was generally positive, with a majority of those surveyed indicating that increased pharmacist involvement in anticoagulation monitoring and dosage adjustment resulted in improved patient care; about 80% indicated that they concurred with pharmacists' recommendations at least 75% of the time. Results of a survey of IAP pharmacists indicated increased satisfaction with their daily duties but also a need for improved pharmacist-to-pharmacist communication. CONCLUSION. Case-based advanced training and implementation of an IAP in a tertiary care hospital increased pharmacists' involvement in the management of inpatients receiving anticoagulants.
