Abstrakt: Aim: Evidence on antithrombotic therapy use in centenarians diagnosed with atrial fibrillation (AF) is sparse. Our objective was to investigate a possible underprescribing in centenarians relative to younger cohorts of the oldest-old. We assumed lower AF rates; and, within AF patients, lower use of anticoagulants in those who died as centenarians (aged ≥100 years) than in those who died aged in their 80s (≥80 years) or 90s (≥90 years).
Methods: The present study was a quarterly structured cohort study over the 6 years before death using administrative data from German institutionalized and non-institutionalized insured patients (whole sample n = 1398 and subsample of AF patients n = 401 subclassified according to age-of-death groups [≥80, ≥90, ≥100 years]). AF, medication, stroke risk (Congestive heart failure; Hypertension; 2 × Age ≥75 years; Diabetes mellitus; 2 × Stroke; Vascular disease; Age 65-74 years; Sex [female] (CHA 2 DS 2 -VASc)) and risk of major bleeding (Hypertension; Abnormal renal and liver function; Stroke; Bleeding; Labile International Normalized Ratio [omitted in the present analysis]; Elderly; Drugs or alcohol (HAS-BLED)) were calculated. Generalized estimation equations were used to model the trajectories.
Results: Half a year before death (T1), AF rates were higher in patients aged ≥80 years (31.8%) and ≥90 years (30.6%) compared with patients aged ≥100 years (22.4%), whereas there were no significant differences between age groups 6 years before death (T0). Of all AF patients with AF at T1, 26.7% received anticoagulants; 11.2% vitamin K antagonists; 15.7% non-vitamin K antagonist oral anticoagulants; and 17.5% platelet inhibitors; yet 58.1% received none of these drugs. Centenarians received significantly fewer anticoagulants compared with the other age groups. Prescriptions of anticoagulants were not associated with CHA 2 DS 2 -VASc with and without adjustment for HAS-BLED.
Conclusions: The present findings highlight the need for more appropriate use of anticoagulation therapy in older patients, as well as for new treatment guidelines taking the heterogeneity of very old patients into account. Geriatr Gerontol Int 2018; 18: 1634-1640.
