Abstract

BACKGROUND: Among Chinese American individuals, only approximately 42% of cases of colorectal cancer (CRC) are diagnosed at an early stage, possibly because these patients are less likely than non-Hispanic white individuals to undergo CRC screening. METHODS: Primary care physicians (PCPs) were recruited from a local independent practice association serving Chinese Americans and randomized into early-intervention and delayed-intervention groups. PCPs in the early-intervention group received continuing medical education (CME), and their patients received an intervention mailer, consisting of a letter with the PCP's recommendation, a bilingual educational booklet, and a fecal occult blood test (FOBT) kit in year 1. PCPs in the delayed-intervention group received no CME, and their patients received the mailers in year 2. RESULTS: A total of 20 PCPs were assigned to the early-intervention and 22 PCPs to the delayed-intervention group. A total of 3120 patients of these participating PCPs who had undergone CRC screening that was due during the study period were included. A total of 915 mailers were sent in year 1 and 830 mailers were sent in year 2. FOBT screening rates increased from 26.7% at baseline to 58.5% in year 1 in the early-intervention group versus 19.6% at baseline to 22.2% in year 1 in the delayed-intervention group (P<.0001). The overall effect size of the mailer intervention with or without CME was estimated as a difference of 26.6 percentage points (95% confidence interval, 22.0-31.2 percentage points) from baseline compared with usual care. The intervention was found to have no impact on rates of colonoscopy or sigmoidoscopy. CONCLUSIONS: The results of the current pilot study demonstrated that a mailer including educational materials and FOBT kits can increase CRC screening rates with or without CME for the PCPs.
