OBJECTIVE: Successful colorectal cancer screening relies in part on physicians ordering a complete diagnostic evaluation of the colon (CDE) with colonoscopy or barium enema plus sigmoidoscopy after a positive screening fecal occult blood test (FOBT).
DESIGN:We surveyed primary care physicians about colorectal cancer screening practices, beliefs, and intentions. At least 1 physician responded in 318 of 413 (77%) primary care practices that were affiliated with a managed care organization offering a mailed FOBT program for patients aged 50 years. Of these 318 practices, 212 (67%) had 602 FOBT+ patients from August through November 1998. We studied 184 (87%) of these 212 practices with 490 FOBT+ patients after excluding those judged ineligible for a CDE or without demographic data. Three months after notification of the FOBT+ result, physicians were asked on audit forms if they had ordered CDEs for study patients. Patient-and physicianpredictors of ordering CDEs were identified using logistic regression.
MEASUREMENTS AND MAIN RESULTS:A CDE was ordered for only 69.5% of 490 FOBT+ patients. After adjustment, women were less likely to have had CDE initiated than men (adjusted odds, 0.66; confidence interval, 0.44 to 0.97). Physician survey responses indicating intermediate or high intention to evaluate a FOBT+ patient with a CDE were associated with nearly 2-fold greater adjusted odds of actually initiating a CDE in this circumstance versus physicians with a low intention.CONCLUSIONS: Primary care physicians often fail to order CDE for FOBT+ patients. A CDE was less likely to be ordered for women and was influenced by physician's beliefs about CDEs.KEY WORDS: colorectal neoplasms; primary health care; occult blood; mass screening; attitude of health personnel.
DCR without silastic intubation is less expensive than DCR with silastic intubation in primary uncomplicated NLDO, and has a similar success rate. DCR with silastic intubation may create increased burden for patients in the form of more post-surgical follow-up visits. In cases of uncomplicated primary NLDO, the use of silastic intubation in DCR may be unnecessary.
Full-thickness mucosal grafts typically maintain their native epithelial morphology following transplantation to the ocular surface. Submucosal glands usually do not survive transplantation, which could be the result of intentional thinning of the graft at the time of transplantation. Contrary to the opinion that hard palate graft epithelium usually undergoes metaplasia from keratinized to nonkeratinized within 6 months following transplantation to the eye, all hard palate grafts in this study remained orthokeratotic and/or parakeratotic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
