We utilized physician-coded diagnoses and chart
reviews to estimate the incidence of
interstitial cystitis (IC) in women. A computer
search of the Kaiser Permanente database was
performed to identify newly coded diagnoses of
IC (ICD-9 code 595.1) between May 2002 and May
2005. Chart reviews were performed and patient
demographics, diagnosing physicians, and symptom
characteristics were recorded. The IC incidence
rate was 15 per 100,000 women per year. The mean
age of the patients was 51 years (range 31-81
years). The most common presenting symptoms were
frequency (70%), dysuria (52%), urgency (50%),
suprapubic pain (50%), nocturia (35%), and
dyspareunia (13%). Cases diagnosed by primary
care physicians had a shorter median symptom
duration (9 months) compared with those
diagnosed by urologists (1 year) and
gynecologists (3 years). IC is an uncommon
diagnosis in the community setting, with an
incidence rate of 15 per 100,000 women per year.
