Implementation of pharmacist-managed anticoagulation clinic in a saudi arabian health center.

BACKGROUND

During the past 2 decades, a paradigm shift in the management of oral anticoagulation therapy has occurred. A multidisciplinary approach has been used and has proved beneficial from both a cost and quality perspective. However, this approach to anticoagulation therapy is not well established in Saudi Arabia and the Middle East, and the traditional way of managing anticoagulation patients is still the mainstay of care. The Pharmacy Services Division (PSD) in collaboration with physician, nursing, and medical support enterprises at the Dhahran Health Center established the pharmacy-managed anticoagulation clinic (ACC).

OBJECTIVE

To describe the implementation process of the first pharmacist-managed anticoagulation clinic in the eastern province of Saudi Arabia and its impact on patient care.

METHODS

The PSD in collaboration with medical staff successfully created a care delivery model utilizing clinical pharmacists' expertise to provide comprehensive anticoagulation management services at Saudi Aramco Medical Services Organization (SAMSO). Planning included analyzing existing practices, reviewing the relevant literature, obtaining physician input, formulating a business proposal, and developing clinical protocols and guidelines. Collaborative relationships were established with the center laboratory, scheduling services, and nursing and medical departments. Clinic services include patient assessment, anticoagulation monitoring, warfarin dosage adjustment, medication dispensing at the clinic, patient education, and feedback to referring physicians. Data (2 years before and after clinic inception) for all patients enrolled at the anticoagulation clinic were reviewed to evaluate the impact of the clinic on anticoagulation management, adverse events, and patient satisfaction.

RESULTS

A total of 578 patients were enrolled in the ACC. The total percentage of international normalized ratio (INR) within the target range was 59% versus 48% when compared to the previous traditional practice. The number of INR tests per patient dropped by 19%. Minor and major adverse events occurred in 10% and 1.5% of patients, respectively. Overall, the patients were very satisfied with the new clinic compared to the previous practice.

CONCLUSION

Implementation of the pharmacist-managed ACC in the eastern province of Saudi Arabia had a positive impact on patient care based on the improvements in the number of patients whose INR was within therapeutic range and patient satisfaction scores.
