Higher Resource Utilization and Costs in Long-Term Nursing Home Residents With Overactive Bladder: A Retrospective Study of Medicare Beneficiaries.

To determine the all-cause health care resource utilization and costs among long-term nursing home (LTNH) residents with and without overactive bladder (OAB).

Retrospective cohort study.

Minimum Data Set (MDS)-linked Medicare Part A, B, and D claims data from 2013 to 2015 were analyzed. LTNH residents aged 65 years or older with a diagnosis of OAB (n = 216,731) were propensity score matched with LTNH residents without OAB (n = 300,327) (non-OAB cohort).

We measured health care resource utilization and costs associated with OAB by setting (inpatient, outpatient, emergency department, or prescription) during the 6 months following nursing home admission. Descriptive and multivariate (negative binomial for health care resource utilization and 2-part model for costs) analyses were performed to examine the health care resource utilization and costs among LTNH residents with and without OAB. The annual cost attributed to OAB was calculated as the difference between total annual OAB costs and total annual non-OAB costs.

A total of 214,505 patients were included in each matched cohort. Across all health care resource categories, LTNH residents with OAB had higher health care resource utilization and costs compared to the non-OAB cohort (all P < .001). The mean annual direct total cost was $57,984 in the OAB cohort compared with $54,285 in the non-OAB cohort. The annual cost of OAB in nursing homes was estimated at $793 million. Adjusted analyses revealed that the OAB cohort was 9% more likely to have hospitalization and emergency department visits, 15% more likely to have outpatient visits, 27% more likely to have physician visits, and 12% more likely to have prescription counts compared with the non-OAB cohort.

The study findings suggest that LTNH residents with OAB have significantly more health care resource utilization compared with patients without OAB. These results provide health care decision makers with recent estimates of the burden of OAB in LTNH to assist them with resource planning.
