Evaluation of the French National Program on Home Return of Patients with Chronic Heart Failure (PRADO-IC): Pilot Study of 91 Patients During Its Deployment in the Bas Rhin Area

Objective: The main objective of this study was to evaluate the impact of the French national program on home return of chronic heart failure patients (PRADO-IC) in terms of re-hospitalizations for heart failure (HF) during its deployment in the Bas-Rhin (France).

Patients and methods: This was a pilot, descriptive, quantitative, retrospective, and bi-centric study (University Hospitals of Strasbourg and Haguenau Hospital Center, France). It included all patients included in the PRADO-IC program from these centers between January 1, 2015 and December 31, 2015. The primary endpoint of our study was the evaluation of the number of 1-year, 6-month, and 30-day re-admissions to the hospital in relation to an acute HF episode, before and after the inclusion of patients in the PRADO-IC program. The secondary endpoints were the number of overall re-hospitalizations (all-cause); the number of days of hospitalization for HF; the time to first re-hospitalization and the average length of hospital stay, before and after inclusion in PRADO-IC; and the overall and cardiovascular mortality rates.

Results: 91 patients out of 271 (33,6%) with a mean age of 79.2 years (67-94) were included. They all had chronic HF, essentially class II-III NYHA (90.1%), mostly of ischemic origin (41.9%), with altered left ventricular ejection fraction in 71.4% of cases. A reduction in the mean number of hospitalizations for HF per patient at 30 days, 6 months and 1 year was observed, respectively, from 0.18 ± 0.42 per patient before inclusion to 0.15 ± 0.36 after inclusion (p = 0.56); 0.98 ± 1.04 hospitalizations to 0.53 ± 0.81 at 6 months (p < 0.01); and 1.64 ± 1.14 hospitalizations 1.04 ± 1.05 at 1 year (p < 0.001). Patients were hospitalized less overall after inclusion in the PRADO-IC program. The number of days of hospitalization for HF was reduced after inclusion of patients from 18.02 ± 7.78 days before inclusion to 14.28 ± 11.57 days for the 6 month follow-up (p = 0.006), and from 22.07 ± 10.33 days before inclusion to 16.39 ± 15.94 days for the 1 year follow-up (p < 0.001). In contrast, inclusion in PRADO-IC statistically increased the mean time to first re-hospitalization for HF from mean 99.36 ± 72.39 days before inclusion to 148.11 ± 112.77 days after inclusion (p < 0.001).

Conclusion: This study seems to demonstrate that the PRADO-IC program could improve the management of chronic HF patients in ambulatory care, particularly regarding HF re-hospitalization. However, due to the limitations of the methodology used and the small number of patients, it is advisable to consolidate its initial results with a randomized controlled study on a larger number of patients. In our opinion, its results need to be communicated because, to our knowledge, no equivalent study exists.
