Dual Healthcare System Use During Episodes of Acute Care Heart Failure Associated With Higher Healthcare Utilization and Mortality Risk.

ABSTRACT: Background Individuals receiving cross-system care (dual users) have higher rates of healthcare utilization and worse outcomes for heart failure ( HF ) and other conditions. Individuals can be dual users or single-system users at different times, though, and little is known about utilization and mortality within discrete episodes of care. Methods and Results A retrospective cohort of 3439 patients with 5231 discrete episodes of HF exacerbation were identified between 2007 and 2011. Episodes encompassed the period from 2 weeks before an initial HF emergency department ( ED ) visit or hospitalization, included any acute care visits within 30 days after initial visit, and ended 30 days after the last acute care visit in the episode chain. All-cause and HF -specific ED visits and hospitalization within 30 days of index visit were analyzed using generalized estimating equations with robust variance. Hazard for death within episodes of acute illness was analyzed using Cox proportional hazards models. In adjusted analyses, dual use acute HF episodes were associated with higher odds of all-cause ED visits (odds ratio 1.61, 95% confidence interval [ CI ], 1.33, 1.95), HF -specific ED visits, (odds ratio 1.54, 95% CI , 1.12, 2.13), all-cause hospitalization (odds ratio 1.89, 95% CI , 1.50, 2.38), and HF -specific hospitalization (odds ratio 1.62, 95% CI , 1.15-2.30) as compared with Veterans Health Administration-only episodes of acute HF care. Dual use episodes of care were associated with higher hazard for mortality (hazard ratio=1.52, 95% CI 1.07, 2.16) as compared with all-Veterans Health Administration episodes of care. Conclusions Episodes of acute HF care spanning across healthcare systems appear to be associated with higher risk of subsequent ED visits, hospitalization, and mortality.

Project description:AimsThe aims of this study were to describe patient characteristics of the adult chronic heart failure (HF) population and to estimate the prevalence, incidence, healthcare resource utilization (HCRU), and mortality associated with HF in Southwest Finland.Methods and resultsThis was a retrospective biobank and clinical registry study. Adult patients with an HF diagnosis (International Statistical Classification of Diseases and Related Health Problems (ICD) code I50) during 2004-2013 in secondary care were included in the study and compared with age-matched and gender-matched control patients without an I50 diagnosis. HF patients were stratified in groups by left ventricular ejection fraction (LVEF) as follows: LVEF < 40% [HF with reduced ejection fraction (HFrEF)]; LVEF ? 40% [HF with preserved ejection fraction (HFpEF)]; or unknown (LVEF unknown). HCRU was stratified by inpatient, outpatient, and emergency room visits. In 2013, the incidence of HF was 3.2/1000, and the prevalence was 13.9/1000 inhabitants (n = 15 594). In the stratified analysis of HF patients (n = 8833, average ± SD age 77.1 ± 11.2), 1115 (12.6%) patients had HFrEF (female 31.3%), 1449 (16.4%) had HFpEF (female 50.9%), and 6269 (71%) had unknown LVEF (female 52.1%). The most common co-morbidities were essential hypertension (58%), chronic elevated serum creatinine (57.3%), atrial fibrillation and flutter (55.1%), and chronic ischaemic heart disease (46.4%). Patients with HF diagnosis had higher HCRU compared with that of age-matched and gender-matched controls (3.7 more days per year at the hospital for HF patients compared with the controls). The total 5 year mortality was 62.6% for HF patients and 28.3% for controls, with higher age being the strongest predictor of mortality. Moreover, multivariable Cox regression analysis showed that patients with HFrEF had a 13% (95% confidence interval 2.7-25%) increased risk of mortality compared with HFpEF patients.ConclusionsThe high mortality rate and HCRU among the studied HF patients highlight the severity of the disease and the economic and social burden on both patients and society. This calls for improved methods of care for this large patient population.

Project description:AimsMultidisciplinary team (MDT) management in heart failure (HF) is recommended to reduce mortality and HF hospitalization. We investigated whether an MDT in a community-based HF unit (HFU) impacted patients' healthcare utilization (HCU) and costs.Methods and resultsA retrospective cohort study was conducted among HF patients who visited at least once in a regional community-based HFU, established for ambulatory specialist care for New York Heart Association Functional Classes III and IV, between January 2012 and August 2019. HCU data were obtained from the health maintenance organization's claims data for 12 months before and after first HFU visit. Multivariable generalized estimating equation models were specified for the annual average change in total healthcare utilization and hospitalization costs. Our cohort consisted of 962 patients, of whom 843 (87.6%) completed at least 12 months of follow-up (Group A) and 119 (12.4%) died within 12 months following their first visit (Group B). Both groups were comparable regarding sex, socio-economic status, Charlson Comorbidity Index, ischaemic heart disease, and/or carotid artery disease. Those who died within 12 months were older and had more hypertension, diabetes, chronic renal disease, and malignancy. There was a significant reduction in the total average annual HCU costs of the entire study population 12 months after the first HFU visit [$12 675 (±17 210) after vs. $13 188 (±15 011) before, P = 0.014]. This was driven by a reduction in costs among patients who completed 12 months of follow-up [$11 955 (±17 352) after vs. $13 112 (±15 268) before, P < 0.001], whereas an increase in these costs was observed among patients who died during follow-up [$17 774 (±15 292) after vs. $13 728 (±13 093) before, P = 0.015]. These opposite trends stem mainly from a decrease [$3540 (±8991) after vs. $4941 (±6806) before, P < 0.001] vs. increase [$10 932 (±11 660) after vs. $6733 (±7215) before, P = 0.002] in hospitalization costs of these groups, respectively. The multivariable models revealed that patients who died within 12 months following the first visit to the HFU demonstrated a significant increase of 57% in hospitalization costs following their first visit [relative risk (RR) = 1.57, 95% confidence interval (CI): 1.20-2.05, P = 0.001], whereas there was a decrease of 34% in the hospitalization costs of patients who completed 12 months of follow-up after their first visit (RR = 0.66, 95% CI: 0.54-0.81, P < 0.001). The entire cohort demonstrated 27% decrease in hospitalization costs following their first HFU visit (RR = 0.73, 95% CI: 0.62-0.87, P < 0.001).ConclusionsIntensification of therapy by a dedicated MDT significantly reduced healthcare utilization and costs, predominantly due to a decrease in hospitalizations.
