A New Hospital-At-Home Model for Integrated Geriatric Care: Data from a Preliminary Italian Experience

Hospital-at-home (HaH) has emerged as an alternative to conventional in-hospital care in older adults, possibly reducing hospital admissions and related complications. This study aimed to describe the characteristics and outcomes of patients referred to "Gruppo di Intervento Rapido Ospedale-Territorio" (GIROT), a HaH service based on comprehensive geriatric assessment, developed in Florence, Italy, during the postpandemic period.

Retrospective longitudinal study.

GIROT provided home-based care to patients with acute or exacerbated chronic diseases and a high risk of hospital-related complications (ie, patients with moderate-to-severe disability and/or dementia), referred from primary care, emergency departments, or in-hospital units.

All-cause mortality and hospitalization rates were assessed at 1, 3, and 6 months, and predictors of 6-month mortality were investigated.

Among 391 patients (mean age, 88.4 years; 62.4% female) referred from emergency departments (58.6%), primary care (27.9%), and acute medical units (13.6%), the main diagnoses were respiratory failure (28.4%), acute heart failure (25.3%), and delirium (13.6%). Patients referred from primary care were older and showed a higher prevalence of severe disability and hypomobility. After 1, 3, and 6 months, mortality rates were 34.5%, 45.6%, and 53.8%, and hospitalization rates 7.2%, 21.5%, and 37.9%, respectively. Predictors of 6-month mortality included age [odds ratio (OR), 1.039], severe disability (OR, 3.446), impossible/assisted walking (OR, 4.450) and referral from primary care (OR, 2.066). High global satisfaction with the service was reported.

The GIROT model may help expanding acute health care capacity for older adults at high risk of hospital-related complications. Customized care plans are needed in patients with severe disability/hypomobility, considering also simultaneous palliative care.
