# Perspectives and Experiences of Doctors and Pharmacists on the Clinical Use of Direct Oral Anticoagulants in Saudi Arabia

## TL;DR

This study explores how doctors and pharmacists in Saudi Arabia use and feel about newer blood thinners called DOACs, finding that they prefer them over older drugs like warfarin.

## Contribution

The study provides insights into DOAC usage and confidence levels among healthcare professionals in Saudi Arabia, highlighting training needs.

## Key findings

- Most participants preferred DOACs over warfarin for anticoagulation therapy.
- Internal medicine residents and hospital pharmacists showed higher confidence in managing DOACs compared to community pharmacists.
- Lexicomp was the most commonly used tool for DOAC-related information.

## Abstract

Background and objectives: Research into clinicians’ and pharmacists’ experiences and perspectives on direct oral anticoagulant (DOAC) use in Saudi Arabia and the broader Middle Eastern area is limited. Therefore, we aimed to evaluate the perspectives and experiences of physicians and pharmacists practicing in Saudi Arabia who prescribe DOACs and dispense DOAC therapy, respectively. Methods: A cross-sectional study was undertaken utilizing an online survey instrument. We collected data via Google Forms. Between June and July 2024, the study questionnaire was distributed to community pharmacists, general practitioners [GPs], cardiologists, residents in internal medicine, and hospital pharmacists (primary and secondary healthcare professionals) working in Saudi Arabia. Results: Comprising 146 doctors and 167 pharmacists, 313 total healthcare professionals participated in the study. Of the weekly DOAC prescriptions, cardiologists had the most at 35%; internal medicine residents came next at 16.3% and general practitioners at 17.5%. Among pharmacists, 16.7% of community pharmacists and 23.9% of hospital pharmacists dispensed DOACs weekly. The most often prescribed and dispensed medications were rivaroxaban, edoxaban, and apixaban. Across all categories, Lexicomp was the most often used tool. Most physicians (98%) said they lowered the DOAC dose when necessary. Especially in dosing, preoperative care, patient education, and medication interaction identification, internal medicine residents and hospital pharmacists expressed more confidence in managing DOACs. In these domains, community pharmacists expressed less trust. Conclusions: This study revealed that most participants preferred newer oral anticoagulants over warfarin and demonstrated a fairly good level of self-perceived knowledge regarding various aspects of the clinical use of DOACs. The study findings highlight the importance of focused training initiatives to standardize the use of DOACs, boost trust among community pharmacists and GPs, and ensure safe and effective patient care.
