Resumen:
AimTo determine the factors associated with discontinuing or not starting oral anticoagulation (OA) therapy in older patients with non-valvular atrial fibrillation (NVAF).
MethodsA prospective, multicenter cohort study was carried out of patients aged >75years with NVAF hospitalized in internal medicine departments in Spain. For each patient, we recorded creatinine, hemoglobin and platelets levels, as well as CHA2DS2-VASc and HAS-BLED scores and the Charlson Comorbidity Index. We measured the ability to carry out basic activities of daily life with the Barthel Index, and the cognitive state with the Short Portable Mental Status questionnaire.
ResultsWe included 723 patients with NVAF, with a mean age of 84.8years (SD 5.2years); 390 (53.9%) of the patients were women. Before admission, 375 (51.9%) patients were treated with OA. Previously diagnosed NVAF (OR 4.099, 95% CI 1.824-9.211, P=0.001), the number of errors in the Short Portable Mental Status questionnaire (OR 1.180, 95% CI 1.020-1.365, P=0.026), peripheral arterial disease (OR 0.285, 95% CI 0.114-0.711, P=0.007) and hemoglobin levels (OR 0.812, 95% CI 0.682-0.966, P=0.019) were independently associated with not starting OA therapy at discharge. Of the 375 patients treated with OA at admission, 87 (23.2%) had their OA discontinued at discharge. The HAS-BLED score (OR 1.516, 95% CI 1.211-1.897, P<0.001) and previous acute myocardial infarction (OR 0.327, 95% CI 0.121-0.883, P=0.027) were associated with the discontinuation of OA.
ConclusionsThere are factors associated with discontinuing or not starting OA in older patients with NVAF, which often have no clinical justification. Geriatr Gerontol Int 2018; 18: 1219-1224.
