Abstract : Pharmacist-managed anticoagulation service (ACS) are responsible for providing the patient education, adjustment of warfarin dosage, monitoring of side effect to maintain pro- thrombin time within the therapeutic range. Many studies have proven the therapeutics effi- ciency of ACS by showing the improvements in warfarin therapy while reducing warfarin related adverse effects. There are several hospitals in Korea that are operating the ACS. The ACS in Seoul Asan Medical Center (AMC) began to provide the ACS for the neurology patients treated with warfarin from April 2003 and its effectiveness remains to be evaluated. The purpose of this study was to evaluate the therapeutic effect of ACS by comparing the achievement rate of INR within the therapeutic range before and after ACS operation and by surveying the patient satis- faction of ACS. We compared the achievement rate of INR values within the therapeutic range during the six-month before the ACS (Pre-ACS) and after the referral to the ACS (Post-ACS).
The study included 58 patients who had been previously managed by physician but now was managed by ACS. We have also surveyed the patient satisfaction of ACS
A total 679 INR values were analyzed pre-ACS group consisted of 285(41%) cases while post-ACS group consisted of 411(59%) cases. The analysis showed that the achievement rate of INR values within the therapeutics range in post-group was significantly superior to the Pre-ACS(65.45%
vs. 47.9%, p≺0.0001). Furthermore post-group spent more time within the therapeutic range than the pre-ACS group (68.08% vs. 50.10%, p≺0.0001). Seventy-nine patients completed the survey on the patient satisfaction. Most patients responded positively with ACS in 18 questions, which correspond with overall satisfaction on ACS, understanding of explanation, knowledge of
