Abstract
PurposeThe goal of this study was to examine treatment patterns, utilization, and costs for complicated urinary tract infections (UTIs) requiring inpatient/emergency department (ED) and outpatient care. MethodsThis observational study evaluated inpatient/ED-treated and outpatient-treated patients (aged ≥18 years) with complicated UTIs from 2 large US administrative claims databases (HealthCore Integrated Research Environment and Premier Perspective Database). Patient identification depended on treatment setting: outpatients had 2 UTI diagnosis–related office visits and 2 claims for different antibiotics within 30 days, and inpatients had a UTI-related hospitalization/ED visit after 1 UTI diagnosis–related office visit plus 2 claims for different antibiotics within 30 days. The index date for outpatients was the date of the first office visit; for inpatients, it was the date of admission/ED visit. Both cohorts had continuous insurance eligibility. Outcomes were assessed by using univariate and multivariate statistics. FindingsThe study sample included 1118 inpatient/ED patients (76.6% female subjects; mean age, 62.4 years) and 41,605 outpatients (85.8% female subjects; mean age, 52.3 years). Mean (SD) pharmacy costs were $2971 ($7650) for inpatient/ED patients and $1882 ($3120) for outpatients during the full treatment period. Index hospitalization/ED averaged $38,422 ($51,161). Mean all-cause 90-day follow-up costs for the inpatient/ED cohort were $34,100 ($71,621) and $11,345 ($34,313) for the outpatient cohort. ImplicationsRelative to outpatient-treated patients, inpatient/ED-treated patients were older, sicker, had higher costs across treatment periods, and had reduced antibiotic use at a lower rate during the 90-day follow-up. Strategies to avoid preventable inpatient/ED visits may help reduce costs in the management of outpatients with complicated UTIs.
