Home Health Care Is Associated With an Increased Risk of Emergency Department Visit, Readmission, and Cost of Care Without Reducing Risk of Complication Following Total Hip Arthroplasty: A Propensity-Score Analysis

Abstract

BackgroundHome health services have long been implemented for patients to receive additional professional care and supervision following discharge from the hospital to theoretically reduce the risk of complications and health care utilizations. The aim of this investigation was to determine if patients assigned home health services exhibited lower rates of medical and surgical complications, health care utilizations, and costs of care following total hip arthroplasty. MethodsA large national database was retrospectively reviewed to identify all primary total hip arthroplasty patients from 2010 to 2019. Patients who received home health services were matched using a propensity score algorithm to a set of similar patients who were discharged home under self-care. We compared medical and surgical complication rates, emergency room visits, readmissions, and 90-day costs of care between the groups. Multivariate regression analyses were performed to determine the independent effect of home health services on all outcomes. There were 7,243 patients who received home health services and were matched to 72,430 patients who were discharged home under self-care. ResultsPatients who received home health services had higher rates of emergency department visits at 30 days (Odds Ratio [OR] R statistical programming software v 3.6.1 [Lucent Technologies, New Providence, RJ] 1.1544; P = .002) as well as increased readmissions at 30 days (OR 1.137; P = .039); complication rates were similar between groups. Episode-of-care costs for home health patients were higher than those discharged under self-care ($14,236.97 versus $12,817.12; P < .001). ConclusionPatients assigned home health care services exhibited higher costs of care without decreased risk of complications and had increased risk of early returns to the emergency department and readmissions.
