Treatment choice, duration, and cost in patients with interstitial cystitis and painful bladder syndrome

Abstract

Introduction and hypothesis

In order to better understand provider treatment patterns for interstitial cystitis (IC)/painful bladder syndrome, we sought to document the therapies utilized and their associated expenditures using a national dataset.

Methods

A cohort was created by applying the ICD-9 diagnosis of IC (595.1) to INGENIX claims for the year 1999. Subjects were followed for 5 years, and patterns of care and related expenditures were evaluated.

Results

Of 553,910 adults insured in 1999, 89 subjects had a diagnosis of IC with 5-year follow-up data. All subjects were treated with oral medication(s), 26% received intravesical treatments, and 22% underwent hydrodistension. Total expenditures per subject were $2,808.

Conclusions

The majority of IC expenditures were attributable to oral medical therapy. Hydrodistension and intravesical instillations were utilized in less than 25% of patients. Hydrodistension was used more frequently among subjects with a new diagnosis; this may reflect its utilization as part of a diagnostic algorithm.
