Evaluation of pharmacist-based compared to doctor-based anticoagulation management in Qatar.

RATIONALE, AIMS AND OBJECTIVES: For over 60 years, warfarin has been the mainstay anticoagulant used in the outpatient setting for the prevention and treatment of a wide variety of thromboembolic clinical conditions. Guidelines recommend that health care providers managing oral anticoagulation therapy should do so in a systematic and coordinated fashion. Studies have shown that, when compared to traditional doctor-based anticoagulation management, pharmacist-managed anticoagulation services can improve patient outcomes. The first pharmacist-based anticoagulation clinic in Qatar was launched in 2013 at Alwakra Hospital. The primary objective of this research was to evaluate the impact of pharmacist versus doctor-based anticoagulation management on the percentage time under therapeutic INR (International Normalized Ratio; TTR), INR within therapeutic range and the extreme out of range INRs. METHOD: A retrospective cohort study was designed to compare the anticoagulation control of pharmacist-based warfarin clinic to the usual doctor-care. RESULTS: Data from 278 patients taking warfarin (78 managed at pharmacist and 200 at doctor-based clinic) were evaluated. Subjects followed at the pharmacist-based clinic had a superior TTR compared to those managed at the doctor-based clinic (81.8% vs. 69.8%, P < 0.001). Additionally, the percentage of visits within therapeutic range were significantly higher in the pharmacist's group compared to doctor's group (76.5% vs. 71.2%, P = 0.011). At the same time, percentage of visits with extreme subtherapeutic INR was reduced in the pharmacist-managed clinic (5.17% vs. 7.05%, P = 0.007) CONCLUSIONS: Our study indicates that pharmacist-based anticoagulation has better INR control when compared to the traditional anticoagulation management. Pharmacist-managed anticoagulation clinics should be considered and supported for warfarin management.

Knowledge, attitudes, and practices of community pharmacists on generic medicines in Qatar.

BACKGROUND: The practice of generic medicines prescribing, dispensing and substitution in developing countries has been controversial among healthcare professionals, particularly due to issues on quality, safety and efficacy. These controversies are as a result of inter-country differences in policies and laws as well as individualized knowledge and attitudes of pharmacists pertaining to generic medicines. OBJECTIVE: This study primarily aims to assess the knowledge, attitudes, and practices of community pharmacists in Qatar towards generic medicines. SETTING: Community pharmacy settings throughout the State of Qatar. METHOD: A cross-sectional study using a pretested paper-based survey was conducted among a random sample of community pharmacists in Qatar. The data were analyzed using IBM-SPSS(®) version 20. Both descriptive and inferential statistical analyses were applied. MAIN OUTCOME MEASURE: Knowledge, attitudes, and practices of generic medicines pertaining to regulatory standards, safety, efficacy, quality, and future policies. Results A total of 160 surveys were distributed to community pharmacists of which 118 were returned (response rate, 74 %). The mean total score of generic medicines knowledge among the pharmacists was 6.8 ± 1.6 (maximum possible score was 10). Years of practice as well as place of obtaining academic degree did not influence knowledge score. Approximately 72 % of the pharmacists supported generic substitution for brand name drugs in all cases where a generic medicine is available and the majority (93 %) agreed that pharmacists should be given generic substitution right. Nearly 61 % of the pharmacists considered lack of proven bioequivalence to original brands as an important barrier for selecting generic medicines and 55 % rated "lack of policy for directing the practice of generic medicine" as an important barrier. CONCLUSION: In order to enhance the quality use of and to promote the practice of generic medicines in Qatar, an educational program should be implemented. A national generic medicine policy and guidelines are warranted in the State of Qatar.
