Appropriateness of prescription of oral anticoagulant therapy in acutely hospitalized older people with atrial fibrillation. Secondary analysis of the SIM-AF cluster randomized clinical trial.

AIMS: To assess the appropriateness of oral anticoagulant (OAC) prescription and its associated factors in acutely hospitalized elderly patients. METHODS: Data were obtained from the prospective phase of SIM-AF (SIMulation-based technologies to improve the appropriate use of oral anticoagulants in hospitalized elderly patients with Atrial Fibrillation) randomized controlled trial, aimed to test whether an educational intervention improved OAC prescription, compared to current clinical practice, in internal medicine wards. In this secondary analysis, appropriateness of OAC prescription was assessed at hospital admission and discharge. RESULTS: For 246 patients, no significant differences were found between arms (odds ratio 1.38, 95% confidence interval [CI] 0.84-2.28) in terms of appropriateness of OAC prescription. Globally, 92 patients (37.4%, 95% CI = 31.6-43.6%) were inappropriately prescribed or not prescribed at hospital discharge. Among 51 patients inappropriately prescribed, 82% showed errors on dosage, being mainly under-dosed (n = 29, 56.9%), and among 41 inappropriately not prescribed, 98% were taking an antiplatelet drug. Factors independently associated with a lower probability of appropriateness at discharge were those related to a higher risk of bleeding (older age, higher levels of aspartate aminotransferase, history of falls, alcohol consumption) and antiplatelet prescription at admission. The prescription of OACs at admission was the strongest predictor of appropriateness at discharge (odds ratio = 7.43, 95% CI = 4.04-13.73). CONCLUSIONS: A high proportion of hospitalized older patients with AF remains inappropriately prescribed or nonprescribed with OACs. The management of these patients at hospital admission is the strongest predictor of prescription appropriateness at discharge

Appropriateness of oral anticoagulant therapy prescription and its associated factors in hospitalized older people with atrial fibrillation.

AIMS: Although oral anticoagulants (OACs) are effective in preventing stroke in older people with atrial fibrillation (AF), they are often underused in this particularly high-risk population. The aim of the present study was to assess the appropriateness of OAC prescription and its associated factors in hospitalized patients aged 65 years or older. METHODS: Data were obtained from the retrospective phase of Simulation-based Technologies to Improve the Appropriate Use of Oral Anticoagulants in Hospitalized Elderly Patients With Atrial Fibrillation (SIM-AF) study, held in 32 Italian internal medicine and geriatric wards. The appropriateness of OAC prescription was assessed, grouping patients in those who were and were not prescribed OACs at hospital discharge. Multivariable logistic regression was used to establish factors independently associated with the appropriateness of OAC prescription. RESULTS: A total of 328 patients were included in the retrospective phase of the study. Of these, almost 44% (N = 143) were inappropriately prescribed OACs, being mainly underprescribed or prescribed an inappropriate antithrombotic drug (N = 88). Among the patients prescribed OACs (N = 221), errors in the prescribed doses were the most frequent cause of inappropriate use (N = 55). Factors associated with a higher degree of patient frailty were inversely associated with the appropriateness of OAC prescription. CONCLUSIONS: In hospitalized older patients with AF, there is still a high prevalence of inappropriate OAC prescribing. Characteristics usually related to frailty are associated with the inappropriate prescribing. These findings point to the need for targeted interventions designed for internists and geriatricians, aimed at improving the appropriate prescribing of OACs in this complex and high-risk population

Simulation-Based Education for Physicians to Increase Oral Anticoagulants in Hospitalized Elderly Patients with Atrial Fibrillation

PURPOSE: This study was intended to determine whether a simulation-based education addressed to physicians was able to increase the proportion of hospitalized elderly with atrial fibrillation prescribed with oral anticoagulants (OACs) compared with the usual practice. METHODS: We conducted a cluster randomized trial (from April 2015 to September 2018) on 32 Italian internal medicine and geriatric wards randomized 1:1 to intervention or control arms. The physicians of wards randomized to intervention received a computer-based e-learning tool with clinical scenarios (Dr Sim), and those of wards randomized to control received no formal educational intervention. The primary outcome was the OAC prescription rate at hospital discharge in the intervention and control arms. RESULTS: Of 452 patients scrutinized, 247 were included in the analysis. Of them, 186 (75.3%) were prescribed with OACs at hospital discharge. No difference was found between the intervention and control arms in the post-intervention phase (odds ratio, 1.46; 95% confidence interval [CI], 0.81-2.64). The differences from the pre- to post-intervention phases in the proportions of patients prescribed with OACs (15.1%; 95% CI, 0%-31.5%) and with direct oral anticoagulants (DOACs) (20%; 95% CI, 0%-39.8%) increased more in the intervention than in the control arm. CONCLUSIONS: This simulation-based course did not succeed in increasing the rate of elderly patients prescribed with OACs at hospital discharge compared with the usual practice. Notwithstanding, over time there was a greater increase in the intervention than in the control arm in the proportion of patients prescribed with OACs and DOACs
