Abstract: Objectives: To identify factors associated with short hospital stays for patients admitted with acute heart failure (AHF) admitted to hospitals with short-stay units (SSU). Material and methods: Multicenter nonintervention study in a multipurpose cohort of patients with AHF to 10 Spanish hospitals with short-stay units; patients were followed prospectively. We recorded demographic data, medical histories, baseline cardiorespiratory and function variables on arrival in the emergency department, on admission, and at 30 days. The outcome variable was a short hospital stay (<= 4 days). We built receiver operating characteristic curves of simple and mixed predictive models for short stays and calculated the area under the curves. Results: A total of 1359 patients with a mean (SD) age of 78.7 (9.9) years (53.9% women) were included; 568 (41.8%) had short stays. Five hundred ninety patients (43.4%) were admitted to SSU and 769 (56.6%) were admitted to conventional wards. The variables associated with a short-stay according to the mixed regression model were hypertensive crisis (odds ratio [OR], 1.79; 95% CI, 1.17-2.73; P=.007) and admission to a SSU (OR, 16.6; 95% CI, 10.0-33.3; P<.001). Hypotensive AHF (OR, 0.49; 95% CI, 0.26-0.91; P=.025), hypoxemia (OR, 0.68; 95% CI, 0.53-0.88; P=.004); and admission on a Wednesday, Thursday, or Friday (OR, 0.62; 95% CI, 0.49-0.77; P<.001) were associated with a long stay. The area under the receiver operating characteristic curve was 0.827 (95% CI, 0.80-0.85; P<.001). Thirty-day mortality and readmission rates did not differ between patients with short vs long stays (mortality, 0.5% in both cases, P=.959; and readmission, 22.9% vs 27.7%, respectively; P=.059). Conclusion: Both clinical and administrative factors are independently related to whether patients with AHF have short stays in the hospitals studied, and among therapy, it is remaslcasle the existence of a SSU.
