Few physicians recommend colorectal cancer (CRC) screening consistently across all modalities. Interventions targeting physician and practice factors are needed to improve CRC screening adherence.
Area of Science:
- Oncology
- Preventive Medicine
- Health Services Research
Background:
- Colorectal cancer (CRC) screening rates are suboptimal in older U.S. adults.
- Physician recommendations are crucial for CRC screening adherence.
- Limited data exist on physician recommendations across the spectrum of CRC screening tests.
Purpose of the Study:
- To investigate physician and practice factors associated with guideline-consistent recommendations for various colorectal cancer screening modalities.
- To identify potentially modifiable factors influencing physician screening advice.
Main Methods:
- Analysis of a nationally representative survey of 1266 U.S. physicians conducted in 2007.
- Assessment of physician and practice characteristics, screening perceptions, and recommendations for fecal occult blood testing (FOBT), flexible sigmoidoscopy (FS), colonoscopy, and double contrast barium enema (DCBE).
- Classification of recommendations as guideline-consistent for all, some, or none of the recommended modalities; statistical analysis using descriptive statistics and polytomous logit regression.
Main Results:
- Only 19.1% of physicians provided guideline-consistent recommendations across all CRC screening modalities they advised.
- Younger physician age, board certification, practice type, fewer patients weekly, and use of electronic medical records were linked to consistent recommendations.
- Greater influence of patient preferences and availability of published clinical evidence also correlated with guideline-consistent advice.
Conclusions:
- Physician recommendations for colorectal cancer screening exhibit both overuse and underuse.
- Few physicians align their recommendations for all screening modalities with established guidelines.
- Targeted interventions addressing modifiable physician and practice factors are essential to enhance CRC screening practices.
