Abstract

Background: The prescribing practice of newer oral anticoagulants (NOACs) has not been adequately studied in the Indian scenario.

Aims: We aimed to describe the prescribing practices of oral anticoagulants, the patient profile and medical comorbidities among patients admitted in a general medicine unit.

Methods: In this retrospective study of the 2742 patients prescribed vitamin- K antagonists (VKAs), during the study period, 150 cases were randomly taken for analysis to match the 105 NOACs cases. Their demographic details, clinical characteristics and treatment details were analyzed.

Results: More than 95% of anticoagulants prescribed were VKAs. The prescription of anticoagulants was more common in men (median age 63 years) for prescription of NOACs and 52 years for VKAs. Dabigatran (60.9%) and warfarin (81.3%) were the most prescribed drugs in their respective classes. The most common indication was for cardiovascular diseases with atrial fibrillation (32%). Diabetes and hypertension were the most common comorbidities in patients prescribed oral anticoagulants with a larger proportion of patients with heart failure being prescribed VKAs ( P < 0.01). Patients in the NOACs group had a higher HAS-BLED high-risk score (33.3% vs. 17.3%; P = 0.002). Logistic regression analysis revealed that patients with co-morbidities of congestive heart failure were more likely to be prescribed VKAs while diabetics were more likely to receive NOACs.

Conclusions: VKAs were the most prescribed anticoagulants; congestive heart failure, diabetes, and hypertension were the commonest comorbidities; and atrial fibrillation was the commonest indication. Patients with a high HAS-BLED score were prescribed NOACs more often.
