Abstract
Aim. To study the structure of anticoagulant prescription in a general hospital to identify trends and contributing factors.Materials and methods. The study was conducted in an urban general hospital. According to retrospective retrieval from electronic health records, total 17,129 patients received anticoagulants from 2008 to 2018. Formal appropriateness of oral anticoagulants (OАС) prescriptions for 6,638 patients with atrial fibrillation (AF) was analyzed with CHA2-DS2-VASc score.Results. Appearance of recommendations for the direct oral anticoagulants (DOAC) prescription in clinical guidelines for venous thromboembolism (VTE) and AF management contributed to steady increase in the DOAC taking and decrease in the proportion of warfarin prescription. From 2011 to 2018, the proportion of patients with DOACs prescription increased from 1.7% to 81.5%. The most common indications for anticoagulant were ischemic stroke prevention in AF and VTE with mean rate 75.3% and 23.2%, respectively for the 2011-2018 period. Steady increase in low-molecular-weight heparin (LMWH) prophylactic prescriptions was also shown (Chi-square for linear trend=1340, df=1, p<0.0001). Since 2014, the prescription of LMWH in prophylactic doses increased dramatically, probably related to implementation of computerized decision support system (CDSS) for VTE prevention in the hospital.Conclusion. The study showed that in a general hospital anticoagulants were prescribed in 19% of hospitalized patient. Not only the new clinical recommendations based on the results of the recent studies on anticoagulants efficacy and safety (external factors), but also implementation standard operating protocols and CDSS, providing physicians current information about the relevant clinical recommendations (internal changes), could influence the appropriateness of anticoagulants prescription.
