Effectiveness of community hospital post-acute care on mortality, re-admission, institutionalization, and activation of a home care programme in Emilia-Romagna region, Italy

Background: In Italy, there is scant evidence on the impact of Community Hospitals (CHs) on clinical outcomes. Aims: To assess the effectiveness of CHs versus long-term care hospital or inpatient rehabilitation facilities on mortality, re-admission, institutionalization, and activation of a home care programme in the Emilia-Romagna Region (ERR-Italy) after acute hospitalisation. Methods: We implemented a cohort study drawing upon the ERR Administrative Healthcare Database System and including hospital episodes of ERR residents subject ≥ 65 years, discharged from a public or private hospital with a medical diagnosis to a CH or to usual care between 2017 and 2019. To control for confounding, we applied a propensity score matching. Results: Patients transferred to CHs had a significantly lower risk of dying but an increased risk of being readmitted to community or acute hospital within 30/90 days from discharge. The hazard of institutionalisation within 30/90 days was significantly lower in the whole population of the CH exposed group but not among patients with cardiac or respiratory chronic diseases or diabetes. The activation of a home care program within 90 days was slightly higher for those who were transferred to a CH. Discussion: The findings of our study show mixed effects on outcomes of patients transferred to CHs compared to those who followed the post-acute usual care and should be taken with cautious as could be affected by the so-called ‘confounding by indication’. Conclusions: The study contributes to the intermediate care available evidence from a region with a well-established care provision through CHs.
