Adherent and non-adherent groups were determined by prescription fill status and provider documentation. The two groups were compared by age, gender, race, ethnicity, insurance type, diagnostic indication for DOAC, pharmacy type, employment status, number of comorbidities, number of home medications and primary language. Univariable and multivariable logistic regressions were applied between the groups and categories. P values &lt;0.05 were deemed significant.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The cohort had 938 patients with non-adherence reported in 227 (24.2%) patients. In multivariable logistic regression, non-adherence was more common in younger patients (OR 1.19, CI 1.03 to 1.37, p=0.020) and in males (OR 1.41, CI 1.02 to 1.95, p=0.039). It was also more frequent among patients prescribing from hospital pharmacies (OR 2.70, CI 1.96 to 3.85, p=0.001) and the employed versus retired (OR 1.92, CI 1.09 to 3.57, p=0.032). Non-adherence was borderline significant in Black Non-Hispanics versus White Non-Hispanics (OR 1.75, CI 0.98 to 3.24, p=0.065) and in White Hispanics versus White Non-Hispanics (OR 1.98, CI 0.89 to 4.43, p=0.095). It was also borderline significant in English primary speakers versus Spanish primary speakers (OR 1.64, CI 0.96 to 2.86, p=0.071).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>DOAC non-adherence in the Bronx is significantly associated with patient age, gender, employment status and prescribing pharmacy type.
