Healthcare resource use and cost burden of urinary incontinence to United States payers.

OBJECTIVE

To assess healthcare resource utilization and costs for female patients diagnosed with stress or mixed urinary incontinence (SUI/MUI) compared to a matched cohort of patients without SUI/MUI.

METHODS

We conducted a retrospective matched cohort study of women using the IBM MarketScan research database. Women diagnosed with SUI/MUI between July 1, 2014 and June 30, 2016 were identified using International Classification of Diseases 9 and 10 codes for SUI or MUI with the date of first diagnosis as the index date from which 2-year postindex healthcare resource use and direct cost data were derived from claims, examined, and compared 1:1 with patients without a SUI/MUI diagnosis, matched by age and Charlson's Comorbidity Index.

RESULTS

A total of 68 636 women with SUI/MUI were matched 1:1 with controls. In the 2-year postindex date, a significantly higher proportion of SUI/MUI patients had ≥1 inpatient visit and ≥1 outpatient visit compared to the control group (inpatient: 18.89% vs. 12.10%, p < 0.0001; outpatient: 88.44% vs. 73.23%, p < 0.0001). Mean primary care visits were significantly higher in SUI/MUI patients compared to controls (7.33 vs. 5.53; p < 0.0001) as were specialist visits (1.2 vs. 0.08; p < 0.0001). Mean all-cause outpatient costs were higher in SUI/MUI patients compared to controls ($7032.10 vs. $3348.50; p < 0.0001), as were inpatient costs ($3990.70 vs. $2313.70; p < 0.0001).

CONCLUSION

Women with SUI/MUI consume significantly higher medical resources and incur higher costs to payers, compared to women without SUI/MUI. While reasons for this are not fully understood, improved and standardized treatment for women with SUI/MUI may positively affect cost and outcomes.
