Patients with long-standing inflammatory bowel disease (IBD) involving at least 1/3 of the colon are at increased risk for colorectal cancer (CRC). Advancements in CRC screening and surveillance and improved treatment of IBD has reduced CRC incidence in patients with ulcerative colitis and Crohn’s colitis. Most cases of CRC are thought to arise from dysplasia, and recent evidence suggests that the majority of dysplastic lesions in patients with IBD are visible, in part thanks to advancements in high definition colonoscopy and chromoendoscopy. Recent practice guidelines have supported the use of chromoendoscopy with targeted biopsies of visible lesions rather than traditional random biopsies. Endoscopists are encouraged to endoscopically resect visible dysplasia and only recommend surgery when a complete resection is not possible. New technologies such as virtual chromoendoscopy are emerging as potential tools in CRC screening. Patients with IBD at increased risk for developing CRC should undergo surveillance colonoscopy using new approaches and techniques.

We examined the relationship between physician adherence with a smoking cessation guideline and organizational structures, policies, leadership support, and physician knowledge and attitudes. A random sample of 844 physicians practicing in 127 VHA hospitals was surveyed. Survey results were aggregated to the hospital level and linked with data on organizational characteristics from the 1998 annual survey of hospitals by the American Hospital Association. Significant predictors of adherence included organizational policies related to nicotine replacement prescriptions, the timing and effectiveness of guideline implementation, physicians' knowledge of VHA clinical guidelines generally, and physicians' beliefs about the receptiveness of patients to smoking cessation.
