A multidisciplinary program based on early care in a day hospital after heart failure hospitalizations. Reduction of 30-day readmissions in patients discharged from cardiology departments

Readmission rates at 30 days after admission for heart failure (HF) are high. Patients admitted in Cardiology are usually younger and with lower comorbidity than the total population with HF. Our department leads a multidisciplinary program for the management of HF (MHFP), based on early post-discharge follow-up in a day hospital, for clinical-analytical assessment, optimization and titration of pharmacological treatment, structured education, promotion of self-care and intravenous treatment if appropriate. The objective of this study is to assess the impact of the MHFP on all cause 30-day readmission rate in our patients (MHFP group), compared with the rest of the Cardiology units in our region (control group).

All discharges with HF main diagnosis in our region were analyzed through anonymized consultation of the Minimum Basic Data Set (a public administrative data base) in the period 2009–2015. The first admission of each patient in the period was identified as index admission, excluding patients who died at that admission and selecting only discharges by Cardiology. Epidemiological characteristics, comorbidities and hospital length of stay were compared in the two groups. The outcome variable was the time to first readmission for any cause in the first 30 days after discharge from index admission. Quantitative variables were compared using Student's t and categorical variables with χ². For the multivariate analysis, Cox method was used.

We included 15,440 patients, 474 in the MHFP group and 14,966 in the control group. The epidemiological characteristics and main comorbidities were compared, and the results are shown in the table. Readmission rate was significantly lower in the MHFP group (9.9 vs 14.2%, HR 0.72, 95% CI: 0.54–0.96 in multivariate analysis). The variables independently associated with an increase in 30-day readmissions were the age-adjusted Charlson index and chronic kidney disease.

Over a period of 6 years, in patients with HF, discharged by Cardiology, a MHFP significantly reduced all cause 30-day readmissions.
