Design and rationale of the atrial fibrillation occurring transiently with stress (AFOTS) follow-up cohort study.

ABSTRACT: Atrial fibrillation occurring transiently with stress (AFOTS) describes the first detection of AF in a patient who is hospitalized for a non-cardiac medical illness or following non-cardiac surgery. Uncertainty exists whether episodes of AFOTS are due to reversible precipitants and will not recur after recovery, or if they are paroxysmal atrial fibrillation (AF) that is detected during inpatient cardiac monitoring. Previous studies have used retrospective, non-systematic and ultimately low-sensitivity protocols to investigate the recurrence of AF in patients with AFOTS. The prospective, multi-center, investigator-initiated AFOTS Follow-Up Cohort Study will enroll 138 case patients with AFOTS in the setting of non-cardiac surgery or medical illness, matched 1:1 with control patients for age, sex, stressor, and hospital unit. Participants will wear a 14-day ECG heart monitor at 1 and 6 months after hospital discharge. Over 12 months of follow-up, we will collect data regarding participant's medications, and clinical events. The primary endpoint is detection of 30 or more seconds of AF after hospital discharge. To date, 50% of the target sample has been enrolled. The study is expected to complete enrolment in mid-2019 and conclude 1 year later. The AFOTS follow-up study will employ a systematic protocol to detect AF and will provide a precise and valid estimate of AF recurrence following AFOTS. This study will establish whether patients with AFOTS have an increased propensity to AF after hospitalization as compared to matched controls and may inform the management of this population.

Project description:BackgroundContinuity of care has been shown to be poor following in-hospital discharge, and there are substantially fewer resources to facilitate follow-up care arrangements after discharge from an emergency department. Our objective was to assess the frequency, timeliness and predictors for obtaining follow-up care following discharge from an emergency department in Ontario with a new diagnosis of atrial fibrillation.MethodsWe conducted a retrospective cohort study involving all patients discharged from the 157 nonpediatric emergency departments in Ontario, who received a new diagnosis of atrial fibrillation between 2007 and 2012. We determined the frequency of follow-up care with a family physician, cardiologist or internist within 7 (timely) and 30 days of the emergency department visit, and assessed the association of emergency and family physician characteristics, including primary care model type, with obtaining timely follow-up care.ResultsAmong 14 907 patients discharged from Ontario emergency departments with a new, primary diagnosis of atrial fibrillation, half (n = 7473) had timely follow-up care. At 30 days, 2678 patients (18.0%) still had not obtained follow-up care. Among emergency and family physician factors, lack of a family physician had the largest independent association with acquiring timely follow-up care (odds ratio [OR] 0.58, 95% confidence interval [CI] 0.50-0.69). Using patients with a family physician belonging to a primarily fee-for-service remuneration model as the comparison group, patients with a family physician belonging to a capitation-based Family Health Network, as part of a Family Health Team, were less likely to receive timely follow-up care (OR 0.73, 95% CI 0.62-0.86), as were those whose family physician belonged to the same model type that was not part of a Family Health Team (OR 0.77, 95% CI 0.60-0.97).InterpretationOnly half of the patients who were discharged from an emergency department in Ontario with a new diagnosis of atrial fibrillation were seen within 7 days of discharge. The most influential factor was having a family physician; patients with a family physician being remunerated via primarily fee-for-service methods were more likely to be seen within 7 days than those who were reimbursed through a primarily capitation model. Systems-wide solutions are needed to ensure timely follow-up care is available for all patients with chronic diseases.
