Risk Factors for Urinary Tract Infection (UTI) Among Home Health Care Patients: Analysis Using Routinely Collected Clinical Data

Background: Urinary tract infection (UTI) is a complication often experienced during a home health care (HHC) episode, yet related hospitalization risk factors are unclear. Objectives: This study use multiple data sources to identify risk factors for UTI related hospitalization or emergency department (ED) visits among HHC patients.Method: We performed a multivariable logistic regression to identify risk factors for UTI-related hospitalization or ED visits using merged data from the Outcome and Assessment Information Set, electronic health record from a large HHC agency, and Center for Medicare and Medicaid claims. Results: Of 48,336 cases, 1,689 patients (3.5%) had a UTI-related hospitalization/ED visits. Being a female (OR = 1.31; 95% CI: 1.16–1.46), the presence of a urinary catheter (OR = 5.7; 95% CI: 4.54–7.14), treatment with general antibacterial and antiseptics (OR = 2.75; 95% CI: 1.02–7.38), dependency in instrumental activities of daily living (e.g., meal preparation [OR=1.72; 95% CI: 1.25-2.37]), and no available caregivers (OR = 1.79; 95% CI: 1.2–2.68) increased the odds of a UTI related event among HHC patients. Discussion/conclusion: We identified notable risk factors for UTI related hospitalization/ER visit, filling a knowledge gap on the currently understudied HHC population. Risk factors identified in this study can be used to proactively identify HHC patients at risk for UTI related hospitalization and target them for preventive interventions. Further research is needed in HHC to develop tailored interventions for at-risk patients.
