Prevalence and predictors of inappropriate prescribing according to the Screening Tool of Older People's Prescriptions and Screening Tool to Alert to Right Treatment version 2 criteria in older patients discharged from geriatric and internal medicine wards: A prospective observational multicenter study.

AIM: To evaluate the prevalence and predictors of potentially inappropriate medications (PIM) and potential prescribing omissions (PPO) in hospital-discharged older patients, according to the recently updated Screening Tool of Older People's Prescriptions and Screening Tool to Alert to Right Treatment version 2 criteria. METHODS: This was a multicenter prospective observational study of patients aged ≥65 years consecutively discharged from geriatric and internal medicine wards. Each patient underwent a comprehensive geriatric assessment, and PIM and PPO at discharge were determined according to the Screening Tool of Older People's Prescriptions and Screening Tool to Alert to Right Treatment version 2 criteria. A multivariate logistic regression was carried out to identify variables independently associated with PIM and PPO. RESULTS: Among 726 participants (mean age 81.5 years, 47.8% women), the prevalence of PIM and PPO were 54.4% and 44.5%, respectively. Benzodiazepines and proton-pump inhibitors were the drugs most frequently involved with PIM, whereas PPO were often related to 5-alpha reductase inhibitors, angiotensin-converting enzyme inhibitors, statins and drugs for osteoporosis. The number of medications (OR 1.22, 95% CI 1.15-1.28) and discharge from geriatric units (OR 0.55, 95% CI 0.40-0.75) were associated with PIM, whereas PPO were independently associated with discharge from geriatric wards (OR 0.44, 95% CI 0.31-0.62), age (OR 1.04, 95% CI 1.02-1.07), comorbidities (OR 1.17, 95% CI 1.04-1.30) and the number of drugs (OR 1.12, 95% CI 1.05-1.18). CONCLUSIONS: Inappropriate prescribing is highly prevalent among hospital-discharged older patients, and is associated with polypharmacy and discharge from internal medicine departments.

Health status, geriatric syndromes and prescription of oral anticoagulant therapy in elderly medical inpatients with atrial fibrillation.

AIM: The aim of the present study was to investigate the prevalence of geriatric syndromes among older medical inpatients with atrial fibrillation, and their association with use of vitamin K antagonists. METHODS: A retrospective study of patients aged ≥65 years discharged with a diagnosis of atrial fibrillation from the Acute Geriatric Ward was carried out. Stroke and bleeding risk were evaluated according to the CHA2 DS2 -VASC and HAS-BLED scores. Comorbidity, cognitive status, functional autonomy and contraindications to vitamin K antagonists were also considered. RESULTS: Atrial fibrillation was documented in 1078 of 3650 patients (29.5%, mean age 83.4 ± 6.6 years, 60.3% women). Contraindications to vitamin K antagonists were documented in 24.9% of patients. Prescription of vitamin K antagonists at discharge was 37.8% and 47.9%, in the overall sample and in those without contraindications, respectively. In the overall sample, prescription of vitamin K antagonists was associated with younger age, permanent/persistent atrial fibrillation, home discharge, less comorbidity, higher hemoglobin levels, better functional independence, known atrial fibrillation at admission and lower HAS-BLED score. Among patients without contraindications to vitamin K antagonists, their use at discharge was independently associated with younger age, permanent/persistent atrial fibrillation, home discharge, higher hemoglobin levels and CHA2DS2-VASC score, better functional autonomy, and greater number of drugs. CONCLUSIONS: We showed a high prevalence of atrial fibrillation among older medical inpatients, who have a poor health status and a high prevalence of geriatric syndromes. Vitamin K antagonists were prescribed in less than half of the patients; underuse was mainly accounted for by a high prevalence of comorbidities/contraindications, poor health status and limited functional autonomy.

Effects of oral anticoagulant therapy in older medical in-patients with atrial fibrillation: a prospective cohort observational study.

BACKGROUND: Uncertainties about efficacy and safety of oral anticoagulant therapy (OAT) among older and frail medical patients with atrial fibrillation (AF) largely contribute to under-prescription of these drugs. AIMS: In this prospective observational cohort study, we investigated mortality, and ischemic and hemorrhagic events, in hospital-discharged older patients with AF. METHODS: Stroke and bleeding risk were evaluated using CHA2DS2-VASC and HAS-BLED scores. Comorbidity, frailty, cognitive and nutritional status and functional autonomy were evaluated using standardized scales. Independent associations between clinical variables, including OAT use, and all-cause mortality, fatal and non-fatal ischemic and hemorrhagic events, were evaluated. Further clinical outcomes comparison between patients treated with OAT and those untreated was performed after adjustment for significant differences in patient baseline characteristics with propensity score matching. RESULTS: Of 452 patients included (mean age 81.6 years, 54.9 % women, roughly 30 % cognitively impaired and/or functionally dependent, mean CHA2DS2-VASC and HAS-BLED scores 4.6 and 2.8, respectively), 151 (33.4 %) died during a mean follow-up period of 300.5 days; ischemic and hemorrhagic stroke occurred in 4.0 and 0.4 % of patients, respectively, and major bleedings in 6.2 %. DISCUSSION: After multivariate analysis, OAT at discharge was associated with lower overall mortality and reduced occurrence of ischemic stroke, the first finding being confirmed in propensity score matched analysis. CONCLUSIONS: Among older vulnerable AF patients with high post discharge death rate, OAT was associated, among other multiple factors, with reduced mortality and lower occurrence of ischemic stroke.

Effects of Oral Anticoagulant Therapy in Medical Inpatients ≥65 Years With Atrial Fibrillation.

In this retrospective cohort observational study, we investigated mortality, ischemic, and hemorrhagic events in patients ≥65 years with atrial fibrillation consecutively discharged from an Acute Geriatric Ward in the period 2010 to 2013. Stroke and bleeding risk were evaluated using CHA2DS2-VASC (congestive heart failure/left ventricular dysfunction, hypertension, aged ≥75 years, diabetes mellitus, stroke/transient ischemic attack/systemic embolism, vascular disease, aged 65 to 74 years, gender category) and HAS-BLED (hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, labile international normalized ratio, elderly, drugs/alcohol concomitantly) scores. Co-morbidity, cognitive status, and functional autonomy were evaluated using standardized scales. Independent associations among clinical variables, including use of vitamin K antagonist-based oral anticoagulant therapy (OAT), all-cause mortality, and fatal and nonfatal ischemic and hemorrhagic events, were evaluated. Further clinical outcomes comparison between patients treated with OAT and those untreated was performed after adjustment for significant differences in patient baseline characteristics with propensity score matching. Of 980 patients discharged (mean age 83 years, 60% women, roughly 30% cognitively impaired or functionally dependent, mean CHA2DS2-VASC and HAS-BLED scores 4.8 and 2.1, respectively), 505 (51.5%) died during a mean follow-up period of 571 days; ischemic and hemorrhagic stroke occurred in 82 (12.3%) and 13 patients (1.3%), respectively, and major bleedings in 43 patients (4.4%). Vitamin K antagonists' use was independently associated with reduced mortality (odds ratio 0.524) and with a nonsignificant reduction in incidence of ischemic stroke, without excess in bleeding risk. Similar findings were observed in the 2 propensity score-matched cohorts of patients. In conclusion, among vulnerable patients with atrial fibrillation ≥65 years with high post-discharge death rate, OAT was associated, among other multiple factors, with reduced mortality.
