ABSTRACT: Background
Patient-reported outcomes in atrial fibrillation (AF) are increasingly used to evaluate treatment efficacy and as endpoints in clinical trials. Few studies have related patient-reported outcomes in AF to clinical events and outcomes. We examined the association between patient-reported outcomes and hospitalization risk in individuals with AF receiving care at a regional healthcare system.Methods and results
We related the AF Effect on QualiTy of Life (AFEQT), a validated measure (range 0-100) with higher scores indicating superior AF-specific patient-reported outcomes, to hospitalization events in a cohort with prevalent AF. We determined incidence rates for hospitalization events (all-cause, cardiac-, or AF-related) across quartiles of AFEQT scores. We used the Andersen-Gill method to account for multiple hospitalization events per individual and compared the risks of hospitalization across AFEQT quartiles in multivariable-adjusted models. In 339 individuals with AF (age 72.3 ± 10.1 years; 43% women) followed for median 2.6 years (range 0-3.4 years), we observed 417 total hospitalization events. We identified increased incidence rates of hospitalization with progressively decreased AFEQT quartile. Relative to those in the highest AFEQT quartile, individuals in the lowest AFEQT quartile had 3-fold greater risk of all-cause hospitalization (95% Confidence Interval [CI] 1.67-6.57, p < 0.001) and 5-fold greater risk of cardiac hospitalization (95% CI 1.66-13.80, p = 0.004).Conclusions
We identified a progressive association between patient-reported outcomes in AF and risk of hospitalization events. Our results underscore the relevance of patient-reported outcomes to clinical adversity and prognosis in AF.

Project description:OBJECTIVES:Women report higher atrial fibrillation (AF) symptom severity and receive less AF therapies than their male counterparts. It is understudied if differences in AF therapies received explains sex differences in AF symptom severity. We investigate the impact of sex and AF therapies on patient-reported outcomes. METHODS:Participants were recruited (n=953) across four academic medical centres with an AF diagnosis and age ≥18 years. Patient-reported outcomes (AF symptom severity, AF-related quality of life, functional status and emotional status) were determined by biannual surveys. We performed multiple linear regressions on propensity-matched cohorts to determine the association of AF therapies and sex on patient-reported outcomes. RESULTS:Our study population (n=953) was 65% male (n=616), 93% white (n=890) and 72 (±10) years old. Individuals receiving rate control therapy reported comparatively lower AF-related quality of life (-7.22, 95% CI -11.51 to -2.92) and poorer functional status (-3.69, 95% CI -5.27 to -2.12). Individuals receiving rhythm control strategies did not report significantly different patient-reported outcomes. Women were more likely to report poorer functional status (-2.63, 95% CI -3.86 to -1.40) and poorer AF-related quality of life, higher anxiety (2.33, 95% CI 1.07 to 3.59), higher symptoms of depression (1.48, 95% CI 0.31 to 2.65) and AF symptom severity (0.29, 95% CI 0.07 to 0.52). CONCLUSIONS:Female sex was associated with comparatively poorer AF symptom severity and quality of life, and this association remained after accounting for AF therapies received. Receiving rate control medication alone was associated with comparatively poorer AF-related quality of life and functional status.

Project description:ObjectivesThis study sought to determine how frequently patient-reported outcomes (PROs) are collected in registered clinical studies of atrial fibrillation (AF).BackgroundImproving symptom burden and quality of life are important goals in the treatment of AF and are best measured with PROs.MethodsData from Clincaltrials.gov were studied to identify PROs in AF studies. All studies reporting AF as the disease condition were included, and PROs were identified by search terms within the outcome measures field. Generic and AF-specific PROs were identified and assessed by study type and year. Clinicaltrials.gov reporting was compared with published reports of linked studies in PubMed.ResultsFrom 1999 to 2018, 1,709 studies including AF patients were posted; 238 studies (14%) included PROs. Collection of PROs was reported in 22% of trials (n = 83 of 386) studying procedural interventions and 11% of all Phase 3 studies (n = 18 of 168). Among the 238 studies with PROs, most described "quality of life" (n = 194 [82%]), and most (n = 198 [83%]) included only generic (not AF-specific) PROs. Only 17% of studies (n = 40) reporting PROs specified a previously published AF-specific tool, most commonly the AFEQT (Atrial Fibrillation Effect on QualiTy-of-life) form (n = 20 [8.4%]). Among the available PubMed citations of 391 studies, 74 studies (19%) described collecting a specific PRO tool (n = 29 [7.4%]) for an AF-specific PRO.ConclusionsDespite increased emphasis on the importance of PROs in AF, a minority of registered clinical trials reported collecting PROs, with very few using validated, AF-specific PROs. Improving outcomes that are most important to patients will necessitate increased emphasis on these PROs in pivotal clinical studies.

Project description:Background The IMPACT-AF (Integrated Management Program Advancing Community Treatment of Atrial Fibrillation) trial is a prospective, randomized, cluster design trial comparing atrial fibrillation management with a computerized clinical decision support system with usual care (control) in the primary care setting of Nova Scotia, Canada. The objective of this analysis was to assess and compare patient-reported health-related quality of life and patient-reported experience with atrial fibrillation care between clinical decision support and control groups. Methods and Results Health-related quality of life was measured using the EuroQol 5-dimensional 5-level scale, whereas patient-reported experience was assessed using a self-administered satisfaction questionnaire, both assessed at baseline and 12 months. Health utilities were calculated using the Canadian EuroQol 5-dimensional 5-level value set. Descriptive statistics and generalized estimating equations were used to compare between groups. Among 1145 patients enrolled in the trial, 717 had complete EuroQol 5-dimensional 5-level data at baseline. The mean age of patients was 73.53 years, and 61.87% were men. Mean utilities at baseline were 0.809 (SD, 0.157) and 0.814 (SD, 0.157) for clinical decision support and control groups, respectively. At baseline, most patients in both groups reported being "very satisfied" with the care received for their atrial fibrillation. There were no statistically significant differences in utility scores or patient satisfaction between groups at 12 months. Conclusions Health-related quality of life of patients remained stable over 12 months, and there was no significant difference in patient satisfaction or utility scores between clinical decision support and control groups.

Project description:BackgroundThere is little information available on AF and its association with outcomes in adult influenza hospitalizations.MethodsThe National Inpatient Sample was queried from years 2009-2018 to create a cohort of discharges containing an influenza diagnosis. AF was the primary exposure. Univariate and multivariate regression analysis was used to describe the association of AF with clinical and healthcare-resource outcomes. Finally, a doubly-robust analysis using average treatment effect on the treated (ATT) propensity score weighting was performed to verify the results of traditional regression analysis.ResultsAfter adjustment, the presence of AF during influenza hospitalization was associated with higher odds of in-hospital mortality (aOR 1.56, 95 % CI 1.49 - 1.65), acute respiratory failure (aOR 1.22, 95 % CI 1.19 - 1.25), acute respiratory failure with mechanical ventilation (aOR 1.37, 95 % CI 1.32 - 1.41), acute kidney injury (aOR 1.09, 95 % CI 1.06 - 1.12), acute kidney injury requiring dialysis (aOR 1.61, 95 % CI 1.46 - 1.78) and cardiogenic shock (aOR 1.90, 95 % CI 1.65 - 2.20, all p-values < 0.0001). These findings were validated in our propensity score analysis using ATT weights. The presence of AF was also associated with higher total charges and costs of hospitalization, as well as a significantly longer length of stay (all p-values < 0.0001).ConclusionAF is a cardiovascular comorbidity associated with worse clinical and healthcare resource outcomes in influenza requiring hospitalization. Its presence should be used to identify patients with influenza at risk of worse prognosis.

Project description:AimsPost-operative atrial fibrillation (POAF) is associated with stroke and mortality. It is unknown if POAF is associated with subsequent heart failure (HF) hospitalization. This study aims to examine the association between POAF and incident HF hospitalization among patients undergoing cardiac and non-cardiac surgeries.Methods and resultsA retrospective cohort study was conducted using all-payer administrative claims data that included all non-federal emergency department visits and acute care hospitalizations across 11 states in the USA. The study population included adults aged at least 18 years hospitalized for surgery without a prior diagnosis of HF. Cox proportional hazards regression models were used to examine the association between POAF and incident HF hospitalization after making adjustment for socio-demographics and comorbid conditions. Among 76 536 patients who underwent cardiac surgery, 14 365 (18.8%) developed incident POAF. In an adjusted Cox model, POAF was associated with incident HF hospitalization [hazard ratio (HR) 1.33; 95% confidence interval (CI) 1.25-1.41]. In a sensitivity analysis excluding HF within 1 year of surgery, POAF remained associated with incident HF hospitalization (HR 1.15; 95% CI 1.01-1.31). Among 2 929 854 patients who underwent non-cardiac surgery, 23 763 (0.8%) developed incident POAF. In an adjusted Cox model, POAF was again associated with incident HF hospitalization (HR 2.02; 95% CI 1.94-2.10), including in a sensitivity analysis excluding HF within 1 year of surgery (HR 1.49; 95% CI 1.38-1.61).ConclusionsPost-operative atrial fibrillation is associated with incident HF hospitalization among patients without prior history of HF undergoing both cardiac and non-cardiac surgeries. These findings reinforce the adverse prognostic impact of POAF and suggest that POAF may be a marker for identifying patients with subclinical HF and those at elevated risk for HF.

Project description:IntroductionPatient-reported outcomes are routinely assessed in atrial fibrillation (AF) to evaluate efficacy of treatment and as clinical trial outcomes. The relation of depression to such measures has had limited study in AF.MethodsIn a cohort receiving treatment for AF, we assessed depression with the Patient Health Questionniare-9 (PHQ; 0-4, normal range; 5-9, mild depression; ?10 moderate depression). We related depression to disease-specific quality of life with the AF Effect on QualiTy of life (AFEQT, range 0-100) and the Global Perceived Stress Scale (GPPS, range 0-24) in multivariable-adjusted models.ResultsIn 260 individuals (age 71.7 ± 10.1, 44.6% women) with AF, 51 (26.1%) had PHQ scores ?5 and 17 (6.5%) ?10. AFEQT scores decreased progressively with depression severity (normal range PHQ, 81.4 ± 14.1; mild depression, 65.8 ± 17.1; moderate depression, 50.6 ± 19.3). Individuals without depression had lower GPPS scores (3.0 ± 2.6) than those with mild (4.9 ± 2.5) or moderate (8.9 ± 4.0) depression. In multivariable-adjusted models mild depression was associated with a 12.1-point (95% confidence interval [CI], -17.2 to -6.9) decrease in AFEQT and 1.9-point (95% CI, 1.1 to 2.7) increase in GPSS, while moderate depression a 27.7-point (95% CI, -35.5 to -19.8) decrease in AFEQT and 5.5-point (95% CI, 4.2 to 6.8) increase in GPSS, relative to normal range PHQ. Regression analyses confirmed significant correlations between depression and AFEQT and GPPS scores in multivariable-adjusted models.ConclusionsWe determined that depression is associated with a step-wise, progressively adverse change in patient-centered outcomes in individuals with AF. Our findings suggest the importance of assessing depression in the evaluation of AF. Subject term list: health services, atrial fibrillation, risk factors.

Project description:ImportanceA primary objective in managing atrial fibrillation (AF) is to optimize patients' health status, which can be done only if physicians accurately quantify the outcomes associated with AF in patients' lives.ObjectiveTo explore physicians' estimation of the health status of patients with AF and its association with subsequent care and outcomes.Design, setting, and participantsA multicenter, prospective cohort study was conducted in 2 outpatient practices in Tokyo, Japan. Participants included patients with newly diagnosed AF or those referred for initial treatment of AF at outpatient practices and treating physicians from November 8, 2018, to April 1, 2020. Data analysis was performed from December 22, 2022, to July 7, 2023.ExposuresParticipating patients completed the Atrial Fibrillation Effect on Quality-of-Life (AFEQT) questionnaire, a 20-item tool covering 4 domains with a 7-point Likert scale; 3 domains (symptoms, daily activities, and treatment concerns) were used in this study. Blinded to patients' responses, treating physicians answered a 3-item questionnaire quantifying each patient's AFEQT domain with a single item. Patients' mean Likert scale responses within each AFEQT domain were subtracted from the physicians' assessments so that higher scores (≥0.5 points) indicate physician underestimation, while lower scores (≤0.5 points) indicate physician overestimation of the health status of patients with AF.Main outcomes and measuresThe independent association of physician-patient concordance with treatment escalation (alteration or initiation of antiarrhythmic drugs, cardioversion, or catheter ablation) and 1-year adjusted changes in AFEQT scores.ResultsAmong 330 patients (238 [72.1%] men; mean [SD] age, 67.9 [11.9] years; 163 [49.4%] with paroxysmal AF), physicians correctly estimated health status in 112 patients (33.9%), underestimated it in 42 patients (12.7%), and overestimated it in 176 patients (53.3%). Treatment escalation occurred in 63.6% of patients whose health status was correctly estimated, 47.6% of those whose health status was underestimated, and 66.3% of patients whose health status was overestimated. After multivariable adjustment, underestimation of health status was independently associated with less treatment escalation (adjusted odds ratio, 0.43; 95% CI, 0.20-0.90) and less frequent AFEQT overall summary score improvement at 1 year (underestimated, 2.5 [95% CI, -1.6 to 6.7] vs correctly and overestimated health status, 8.4 [95% CI, 7.0-9.9] points; P = .01).Conclusions and relevanceIn this cohort study, physician underestimation of the health status of patients with AF was common and associated with less aggressive treatment and less health status improvement at 1 year.

Project description:Patient-reported outcome measures (PROMs) provide a wholesome view of patient well-being. We conducted a retrospective cohort study to evaluate whether PROMs inform risk of unplanned healthcare utilization in patients with IBD. We identified adult patients with IBD who completed at least two surveys in a large Internet-based cohort within 1 year. We evaluated the association between baseline patient characteristics, disease activity indices, medication use, and PROMs, assessed using NIH Patient-Reported Outcome Measurement Information System (PROMIS) and subsequent risk of incident hospitalization (at time of first follow-up) within 1 year, and readmission within 1 year (in patients with hospitalization at first follow-up), using multivariable logistic regression. Of 7902 patients with IBD (45.5 year, 72% females, 63% Crohn's disease), 1377 (17.4%) were hospitalized within 1 year. Among PROMs, pain interference (adjusted OR per 5-point increase in PROMIS, 1.09; 95% CI 1.05-1.14), but not depression, anxiety, fatigue or sleep disturbance, was predictive of higher risk of hospitalization. Prior surgery or hospitalization, symptomatic disease, biologic, and corticosteroid use were also associated with higher risk of hospitalization. Of 521 patients hospitalized with IBD, 133 (25.5%) were readmitted within 1 year. Anxiety and pain interference were predictive of higher risk of readmission, whereas depression was associated with lower risk of readmission. In a large Internet-based cohort study, PROMs may have a modest effect on modifying risk of unplanned healthcare utilization in patients with IBD, with pain interference being most consistently associated with increased risk of hospitalization and readmission.

Project description:BackgroundAtrial fibrillation is a large and growing burden across all types of healthcare. Both incidence and prevalence are expected to double in the next 20 years, with huge impact on hospital admissions, costs and patient quality of life. Patient wellbeing determines the management strategy for atrial fibrillation, including the use of rhythm control therapy and the clinical success of heart rate control. Hence, evaluation of quality of life is an emerging and important part of the assessment of patients with atrial fibrillation. Although a number of questionnaires to assess quality of life in atrial fibrillation are available, a comprehensive overview of their measurement properties is lacking.Methods and resultsWe performed a systematic review of the measurement properties of atrial fibrillation-specific health-related quality of life questionnaires. Methodological quality was assessed using the Consensus based Standards for selection of health Measurement Instruments (COSMIN) checklist, with measurement properties rated for quality against optimal criteria and levels of evidence. We screened 2,216 articles, of which eight articles describing five questionnaires were eligible for inclusion: Atrial Fibrillation 6 (AF6), Atrial Fibrillation Effect on QualiTy-of-Life (AFEQT), Atrial Fibrillation Quality of Life Questionnaire (AFQLQ), Atrial Fibrillation Quality of Life (AFQoL), and Quality of Life in Atrial Fibrillation (QLAF). Good reliability (internal consistency and test-retest reliability) was demonstrated for AF6, AFEQT, AFQLQ and AFQoL. Content, construct and criterion validity were positively rated only in AFEQT. Responsiveness was positively rated only in AFEQT, but with limited evidence. Overall, AFEQT showed strong positive evidence for 2 of 9 measurement properties, compared to one for AFQoL and none for the remaining questionnaires.InterpretationGiven the low ratings for many measurement properties, no single questionnaire can be recommended, although AFEQT performed strongest. Further studies to robustly assess reliability, validity and responsiveness of AF-specific quality of life questionnaires are required. This review consolidates the current evidence for quality of life assessment in patients with atrial fibrillation and identifies priority areas for future research.

Project description:CONTEXT:Although the heritability of atrial fibrillation (AF) is established, the contribution of familial AF to predicting new-onset AF remains unknown. OBJECTIVE:To determine whether familial occurrence of AF is associated with new-onset AF beyond established risk factors. DESIGN, SETTING, AND PARTICIPANTS:The Framingham Heart Study, a prospective community-based cohort study started in 1948. Original and Offspring Cohort participants were aged at least 30 years, were free of AF at the baseline examination, and had at least 1 parent or sibling enrolled in the study. The 4421 participants in this analysis (mean age, 54 [SD, 13] years; 54% women) were followed up through December 31, 2007. MAIN OUTCOME MEASURES:Incremental predictive value of incorporating different features of familial AF (any familial AF, premature familial AF [onset ?65 years old], number of affected relatives, and youngest age of onset in a relative) into a risk model for new-onset AF. RESULTS:Across 11,971 examinations during the period 1968-2007, 440 participants developed AF. Familial AF occurred among 1185 participants (26.8%) and premature familial AF occurred among 351 participants (7.9%). Atrial fibrillation occurred more frequently among participants with familial AF than without familial AF (unadjusted absolute event rates of 5.8% and 3.1%, respectively). The association was not attenuated by adjustment for AF risk factors (multivariable-adjusted hazard ratio, 1.40; 95% confidence interval [CI], 1.13-1.74) or reported AF-related genetic variants. Among the different features of familial AF examined, premature familial AF was associated with improved discrimination beyond traditional risk factors to the greatest extent (traditional risk factors, C statistic, 0.842 [95% CI, 0.826-0.858]; premature familial AF, C statistic, 0.846 [95% CI, 0.831-0.862]; P = .004). Modest changes in integrated discrimination improvement were observed with premature familial AF (2.1%). Net reclassification improvement (assessed using 8-year risk thresholds of <5%, 5%-10%, and >10%) did not change significantly with premature familial AF (index statistic, 0.011; 95% CI, -0.021 to 0.042; P = .51), although categoryless net reclassification was improved (index statistic, 0.127; 95% CI, 0.064-0.189; P = .009). CONCLUSIONS:In this cohort, familial AF was associated with an increased risk of AF that was not attenuated by adjustment for AF risk factors including genetic variants. Assessment of premature familial AF was associated with a very slight increase in predictive accuracy compared with traditional risk factors.
