Dallas KB, Bresee C, De Hoedt A, et al. - The study demonstrated a high rate of misdiagnosis of interstitial cystitis/bladder pain syndrome (IC/BPS) overall, with only 48.8% of patients with an ICD code for IC/BPS meeting diagnostic criteria. No significant relationships were observed between diagnostic accuracy and race/ethnicity. At a younger age, Black and Hispanic patients were more likely to receive a diagnosis of IC/BPS, implying there may be differing natural histories or presentation patterns of IC/BPS between racial/ethnic groups.

• IC/BPS criteria were met in only 651 (48.8%) of the 1,334 charts with an ICD code for IC/BPS reviewed in depth.

• No differences were observed in the misdiagnosis rate by race (p=0.27) or by ethnicity (p=0.97), after adjusting for differences in age and gender.

• Female patients were diagnosed at a younger age than males in IC/BPS-confirmed cases.

• In comparison with white patients, Black and Hispanic patients were diagnosed at a younger age (41.9 vs. 50.2 years, p<0.001) and non-Hispanic patients, respectively (41.1 vs. 49.1 years, p=0.002).
