Background: Direct oral anticoagulants (DOACs) have significantly transformed anticoagulant therapy, improving effectiveness, safety, and convenience in managing thromboembolic conditions. However, concerns persist regarding drug-related problems (DRPs) associated with DOACs, necessitating the establishment of multidisciplinary antithrombotic stewardship programs to optimize the selection, dosing, and monitoring of DOACs.

Objectives: To evaluate the incidence and types of DRPs associated with DOACs, the frequency of clinical pharmacist consultations, the acceptance rates of the clinical pharmacist recommendations, and physicians' adherence to appropriate DOACs prescribing practices.

Methods: A retrospective cohort study was conducted over 4 months in the internal medicine departments at Shamir Medical Center (Assaf Harofeh), Israel. The study included patients aged 18 years and older who were prescribed DOACs (apixaban, rivaroxaban, and dabigatran). Data on patient characteristics and clinical outcomes were collected from electronic medical records. A clinical pharmacist reviewed and reassessed the appropriateness of DOAC prescribing.

Results: During the study period, 415 patients receiving DOACs were identified. Among them, 28.4% had inappropriate DOAC prescriptions leading to 128 recommended interventions. The most common DRP was underdosing (29.7%) followed by unjustified antiplatelet use (26.6%). Clinical pharmacists performed 85.9% of the interventions, with a physician acceptance rate of 72.7%. Patients with inappropriate DOAC prescriptions exhibited increased trends in thromboembolic events and in-hospital mortality.

Conclusions: Despite over a decade of clinical experience with DOACs, DRPs remain a significant challenge. Implementing antithrombotic stewardship programs is critical for optimizing DOACs use, reducing DRPs, and enhancing patient safety.

Background: Medication errors are a common cause of morbidity and mortality.

Objectives: To evaluate the rate of acknowledgment of medication errors as reported by physicians working in the community and in hospitals.

Methods: An anonymous questionnaire was sent to 9320 active physicians (about 48% community physicians, 17% hospital physicians and 35% working in both places), with questions on the rate and type of medication errors that they had encountered during their professional career. The questions specified errors in dosage, type of medicine (wrong indication), route of administration and drug interactions.

Results: Only 627 physicians (6.7%) responded. Of these, nearly 79% admitted having made an error in prescribing medication; the majority admitted to more than one error. Physicians with fewer years of experience admitted having made a mistake more than did physicians with more experience (P = 0.019). Pediatricians and geriatricians made more dosage mistakes (P = 0.02), while family physicians and psychiatrists made more mistakes in drug interactions (P = 0.001).

Conclusions: It is possible that indifference, fear of identification, or lack of awareness may have contributed to the low response rate despite the fact that the questionnaire was anonymous. Educational programs should be implemented in medical schools to encourage physicians to report errors before the onset of adverse reactions.
