Factors Associated With Length of Stay and Readmission Rates for Older Hospital in the Home Patients: A Systematic Review

Abstract

Objective: The aim of this study is to conduct a systematic review of published literature to examine factors associated with Length of Stay (LOS) and Readmission Rates for older Hospital in the Home (HITH) patients. Method: In accordance with PRISMA guidelines, seven databases were searched for peer-reviewed articles relating to HITH, older patients, LOS and readmissions. Results: Twenty-nine studies met the inclusion criteria. Risk factors associated with increased readmissions and LOS were age, prior hospitalisations, illness severity, geriatric-related complications, and cognitive impairment. Most studies found that patients participating in HITH had a shorter initial acute hospitalisation LOS than patients transferred to a subacute hospital or rehabilitation ward. However, LOS and readmissions, comparing HITH to traditional in-hospital care, were inconsistent. Conclusions: Overall, LOS and readmission rates (comparing home-based care to hospital care) were inconsistent but appear related to patient demographics and disease profile and require further study.
