Objective: Direct oral anticoagulants have been evaluated in the general population, but proper evidence for their safe use in the geriatric population is still missing. We compared the bleeding risk of a direct oral anticoagulant (rivaroxaban) and vitamin K antagonists (VKAs) among French geriatric patients with non-valvular atrial fibrillation (AF) aged ≥80 years.Methods: We performed a sequential observational prospective cohort study, using data from 33 geriatric centres. The sample comprised 908 patients newly initiated on VKAs between September 2011 and September 2014 and 995 patients newly initiated on rivaroxaban between September 2014 and September 2017. Patients were followed up for up to 12 months. One-year risks of major, intracerebral, gastrointestinal bleedings, ischaemic stroke and all-cause mortality were compared between rivaroxaban-treated and VKA-treated patients with propensity score matching and Cox models.Results: Major bleeding risk was significantly lower in rivaroxaban-treated patients (7.4/100 patient-years) compared with VKA-treated patients (14.6/100 patient-years) after multivariate adjustment (HR 0.66; 95% CI 0.43 to 0.99) and in the propensity score-matched sample (HR 0.53; 95% CI 0.33 to 0.85). Intracerebral bleeding occurred less frequently in rivaroxaban-treated patients (1.3/100 patient-years) than in VKA-treated patients (4.0/100 patient-years), adjusted HR 0.59 (95% CI 0.24 to 1.44) and in the propensity score-matched sample HR 0.26 (95% CI 0.09 to 0.80). Major lower bleeding risk was largely driven by lower risk of intracerebral bleeding.Conclusions: Our study findings indicate that bleeding risk, largely driven by lower risk of intracerebral bleeding, is lower with rivaroxaban than with VKA in stroke prevention in patients ≥80 years old with non-valvular AF.

Introduction: Integrated care is a particularly promising approach in geriatrics - a field in which the medical, psychological and social issues are often complex. The uptake of integrated care by healthcare professionals (HCPs) is essential but varies markedly. The objective of the present study of healthcare professionals was to identify barriers to and facilitators of commitment to integrated care for seniors. Methods: We performed a two-step, qualitative study, comprising (i) six qualitative, semi-directive series of interviews with HCPs (hospital practitioners, family physicians, nurses and pharmacists) who agreed or disagreed to take part in the French national "Health Pathway of Seniors for Preserved Autonomy" (PAERPA) pilot program; and (ii) an analysis of the pooled results, in order to identify common concerns among the healthcare professionals. Results: We identified four key "barrier" and "facilitator" topics shared by HCPs who had committed to the pilot program and those who had not: (i) awareness of and/or interest in geriatric medicine and team working, (ii) the presence of a care coordinator; (iii) the provision of information about the program and about the patient, and communication between HCPs, and (iv) personal benefits for the HCPs and the patients. Key conclusions: The four key topics identified in this large qualitative study of several healthcare professions should be considered during the design and dissemination of integrated care pathways for older patients.

Background consideration of the first hospital re-admission only and failure to take account of previous hospital stays, which are the two significant limitations when studying risk factors for hospital re-admission. The objective of the study was to use appropriate statistical models to analyse the impact of previous hospital stays on the risk of hospital re-admission among older patients. Methods an exhaustive analysis of hospital discharge and health insurance data for a cohort of patients participating in the PAERPA ('Care Pathways for Elderly People at Risk of Loss of Personal Independence') project in the Hauts de France region of France. All patients aged 75 or over were included. All data on hospital re-admissions via the emergency department were extracted. The risk of unplanned hospital re-admission was estimated by applying a semiparametric frailty model, the risk of death by applying a time-dependent semiparametric Cox regression model. Results a total of 24,500 patients (median [interquartile range] age: 81 [77–85]) were included between 1 January 2015 and 31 December 2017. In a multivariate analysis, the relative risk (95% confidence interval [CI]) of hospital re-admission rose progressively from 1.8 (1.7–1.9) after one previous hospital stay to 3.0 (2.6–3.5) after five previous hospital stays. The relative risk [95%CI] of death rose slowly from 1.1 (1.07–1.11) after one previous hospital stay to 1.3 (1.1–1.5) after five previous hospital stays. Conclusion analyses of the risk of hospital re-admission in older adults must take account of the number of previous hospital stays. The risk of death should also be analysed. [ABSTRACT FROM AUTHOR]

Résumé: La fibrillation atriale (FA) est fréquente chez le sujet âgé. Son traitement repose sur les anticoagulants pour prévenir un accident vasculaire cérébral (AVC) et les emboles systémiques. Les antagonistes de la vitamine K (AVK) ont longtemps été les seuls anticoagulants disponibles pour la prise en charge de la FA. Leur maniement complexe en a fait une des principales causes de iatrogénie chez le sujet âgé. Depuis près de 10 ans, les anticoagulants oraux d'action directe (AOD) ont fait leur apparition et de grands essais randomisés (RE-LY, ROCKET-AF, ARISTOTLE, ENGAGE-AF) ont montré leur supériorité par rapport aux AVK dans la prise en charge de la FA. Ces essais ont été menés sur un très grand nombre de patients (n = 71 683), dont 27 500 ≥ 75 ans et près de 8 000 sujets > 80 ans. Les résultats de 11 méta-analyses récentes regroupant les données des essais randomisés et celles des études observationnelles de la « vraie vie » chez 660 896 personnes âgées indiquent que les AOD ont une meilleure efficacité que les AVK pour prévenir les accidents vasculaires cérébraux (AVC) (réduction du risque allant de 13 % à 26 %), et par rapport à ceux-ci présentent un moindre risque d'hémorragies cérébrales (réduction du risque de 50 %). Le risque d'hémorragie majeure apparaît lui, similaire ou moindre sous AOD que sous AVK (en fonction de la posologie, de la fonction rénale, du site hémorragique ou du type d'AOD). Par ailleurs, le bénéfice des AOD en comparaison aux AVK est retrouvé dans les analyses en sous-groupes chez les sujets de plus de 75 ans, chez les insuffisant rénaux (clairance créatine 30-50 mL/min) et chez les sujets chuteurs. Les analyses indiquent qu'en comparaison avec les AVK, les AOD apparaissent d'autant plus favorables que les patients sont âgés car ce sont eux qui présentent le plus haut risque d'AVC et d'hémorragies cérébrales. En résumé, les AOD présentent un profil efficacité/tolérance supérieur aux AVK, ce qui justifie leur utilisation en première intention chez le sujet âgé de plus de 75 ans. Atrial fibrillation (AF) is common in the elderly. The treatment of this condition is based on anticoagulation in preventing Stroke and systemic arterial embolism. Vitamin K antagonists (VKAs) have long been the only anticoagulants available for the management of AF. Difficulties handling VKAs have made them one of the main causes of iatrogenic disease in the elderly. In the last 10 years, direct-acting oral anticoagulants (DOACs) have emerged and large randomized trials (RE-LY, ROCKET-AF, ARISTOTLE, ENGAGE-AF) have demonstrated their superiority over VKAs in the management of AF. These trials were conducted with large numbers of patients (n=71,683), including 27,500 aged ≥75 years and nearly 8,000 subjects aged >80 years. Results from 11 recent meta-analyses of randomized trials and observational real-world studies of 660,896 elderly patient indicate that DOACs are more effective than VKA-based prophylaxis in preventing stroke (risk reduction ranging from 13% to 26%) and carry a lower risk of cerebral hemorrhage (risk reduction 50%). The risk of major hemorrhage appears to be similar to or lower with DOACs than with VKAs (depending on the dosage, renal function, hemorrhagic site or type of DOACs). Moreover, a greater benefit of DOACs over VKA therapy has been found in subgroup analyses in subjects aged over 75 years, in patients with renal insufficiency (creatinine clearance 30-50 mL/min) and in those with a history of falls. Analyses indicate that DOACs are a better choice than VKAs in the elderly because elderly patients are those with the highest risk of stroke and cerebral hemorrhages. In summary, DOACs have a better efficacy/tolerance profile than VKAs, which justifies their first-line use in subjects over 75 years of age. [ABSTRACT FROM AUTHOR]

Drug‐induced hyperkalemia is a frequent and severe complication in the hospital setting. Other risk factors may also induce hyperkalemia but the combination of drugs and precipitating factors has not been extensively studied. The aim was to identify drug‐induced hyperkalemia events in hospitalized older patients and to describe their combinations with precipitating factors. Two experts independently analyzed retrospective data of patients aged 75 years or more. Experts identified 471 hyperkalemia events and concluded that 379 (80.5%) were induced by drugs. The cause was multifactorial (i.e., at least one drug with a precipitating factor) in 300 (79.2%) of the 379 drug‐induced hyperkalemia. Most of the drug‐induced hyperkalemia events were avoidable (79.9%)—mainly because of the multifactorial cause (e.g., dosage adaptation during acute kidney injury). Drug‐induced hyperkalemia events are frequently combined with precipitating factors in hospitalized older patients and their prevention should focus on these combinations. [ABSTRACT FROM AUTHOR]

Background: Several studies have shown that the prescription of antiplatelet therapy (APT) is associated with an increased risk of oral anticoagulant (OAC) underuse in patients aged 75 years and over with atrial fibrillation (AF). An associated atheromatous disease may be the underlying reason for APT prescription. The objective of the study was to determine whether the association between underuse of OAC and APT prescription was explained by the presence of an atheromatous disease. Methods and Results: We performed a retrospective, observational, single-centre study between 2009 and 2013 based on administrative data. Patients aged 75 years and over with non-valvular AF were identified in a database of 72,090 hospital stays. Prescriptions of anti-thrombotic medications and their association with the presence of atheromatous disease were evaluated by the mean of a logistic regression. A total of 2034 hospital stays were included (mean age 84.3 ± 5.2 years). The overall prevalence of known atheromatous disease was 25.9%. OAC underuse was observed in 58.5% of the stays. In multivariable analysis, the prescription of an APT was associated with an increased risk of OAC underuse [odds ratio (OR) 6.85; 95% confidence interval (CI) 5.50-8.58], independently of the presence of a concomitant known atheromatous disease (OR 0.78; 95% CI 0.60-1.01). Among the 692 stays with APT monotherapy (34.0%), 232 (33.5%) displayed an atheromatous disease. Conclusions: The underuse of OAC is associated with the prescription of APT in older patients with AF, regardless of the presence or absence of known atheromatous disease. Our results suggest that APT is often inappropriately prescribed instead of OAC. [ABSTRACT FROM AUTHOR]
