Objective: This study described older patients receiving hospitalisation-at-home (HaH) services and identified factors associated with 30-day hospital readmission.
Design: 3-year retrospective study in 2017-2019 in France.
Participants: 75 108 patients aged 75 years and older who were discharged from hospital medical wards (internal medicine and geriatric units) and admitted to HaH.
Primary outcome measure: 30-day hospital readmission.
Results: The mean age of patients was 83.4 years (SD 5.7), 52.3% were male and 88.4% lived in a private household. Patients were primarily discharged from the internal medicine unit (85.3%). The top four areas of care in the HaH were palliative care, complex dressing, intravenous therapy and complex nursing care. Overall, 23.5% of patients died during their HaH stay and 27.8% were readmitted to the hospital at 30 days. In the multivariate model, male (OR 1.19, 95% CI 1.16 to 1.23), supportive cancer HaH care (OR 1.78, 95% CI 1.51 to 2.11) and very high intensity care during the previous in-person hospitalisation (OR 1.45, 95% CI 1.34 to 1.57) increased the risk of hospital readmission at 30 days. Older age (OR 0.97, 95% CI 0.97 to 0.98), living in a nursing home (OR 0.51, 95% CI 0.48 to 0.54), postsurgery HaH care (OR 0.49, 95% CI 0.41 to 0.58) and having been previously hospitalised in a geriatric unit (OR 0.81, 95% CI 0.77 to 0.85) decreased the risk of hospital readmission at 30 days.
Conclusions: HaH provides complex care to very old patients, which is associated with high mortality. Several factors are associated with rehospitalisation within 30 days that could be avoided with better integration of different services with higher geriatric skills.
