Abstract:
Background: Evidence points to unequal access to direct oral anticoagulant (DOAC) therapy, to the detriment of the most socioeconomically disadvantaged patients in different geographic areas; however, few studies have focused on people with atrial fibrillation. This study aimed to assess gender-based and socioeconomic differences in the prescriptions of anticoagulants in people with non-valvular atrial fibrillation who attended Primary Care. Method: A cross-sectional study with real-world data from patients treated in Primary Care in Catalonia (Spain). Data were obtained from the SIDIAP database, covering 287 Primary Care centers in 2018. Results were presented as descriptive statistics and odds ratios estimated by multivariable logistic regression. Results: A total of 60,978 patients on anticoagulants for non-valvular atrial fibrillation were identified: 41,430 (68%) were taking vitamin K antagonists and 19,548 (32%), DOACs. Women had higher odds of treatment with DOAC (adjusted odds ratio [ORadj] 1.12), while lower DOAC prescription rates affected patients from Primary Care centers located in high-deprivation urban centers (ORadj 0.58) and rural areas (ORadj 0.34). Conclusions: DOAC prescription patterns differ by population. Women are more likely to receive it than men, while people living in rural areas and deprived urban areas are less likely to receive this therapy. Following clinical management guidelines could help to minimize the inequality.
