Variation in recommendations for cancer screening among primary care physicians in New Mexico

The acceptance of age-appropriate cancer screening as an integral part of primary care has grown among physicians over the past decade. We conducted a mailed survey of all primary care physicians in New Mexico in order to better understand their current cancer screening practices. We found a high rate of self-reported screening, particularly for prostate and colorectal cancer. The screening rates were influenced only slightly by the introduction of evidence-based guidelines, with younger physicians and those with university affiliations more likely to follow recommendations. Female physicians and obstetrician-gynecologists endorsed breast and cervical cancer screening among all age groups and were less likely to follow recommendations for less frequent screening in women as they age. Since a physician's practice beliefs influence his/her attitude toward testing, tailoring education by physician specialty may be more effective than using generic messages in encouraging compliance with the most recent evidence-based guidelines.
