Colorectal cancer screening among underserved minority population: discrepancy between physicians' recommended, scheduled, and completed tests.

OBJECTIVE

This study examines the correlates of: (1) health care provider recommendation of CRC testing; (2) provider scheduling for recommended CRC testing using sigmoidoscopy, colonoscopy, or double-contrast barium enema; and (3) adherence to CRC scheduling among underserved minority populations.

METHODS

Medical record and schedule logbook reviews and interviewer-administered surveys.

SETTING

Large urban safety-net, outpatient primary care setting in Los Angeles County.

PARTICIPANTS

306 African-American and Latino patients aged 50 years and older.

RESULTS

A vast majority of minority patients do not receive standard CRC testing in urban safety-net primary care settings. Of those patients who were actually scheduled for sigmoidoscopy or colonoscopy, almost half completed the procedure. Completing CRC testing was associated with marital status, co-morbid chronic physical conditions, number of risk factors for colorectal cancer, and lower perceived barriers to CRC testing.

CONCLUSION

Effective interventions to reduce CRC mortality among underserved minority populations require an integrated approach that engages patients, providers, and health care systems.

PRACTICE IMPLICATIONS: Designing interventions that (1) increase physician-patient communications for removing patients' perceived barriers for CRC testing and (2) promote a non-physician-based navigator system that reinforces physicians' recommendation are strongly recommended.
