Screening for colorectal cancer in personnel of an academic medical center.

The colorectal cancer (CRC) screening program in Israel offers the average-risk population fecal occult blood tests from the age of 50 years. Compliance, however, is very low, reaching only 6% of eligible persons in 2005. Our aim in this study was to describe the results of an improved CRC screening program directed at the in-house staff of Beilinson Hospital. All employees of Beilinson Hospital over age 50 years were sent a letter explaining the new CRC screening program and an accompanying questionnaire. Responders who reported a family history of CRC or related cancers or symptoms were offered colonoscopy; the remainder were offered sigmoidoscopy or, if they preferred, colonoscopy. Two hundred twenty of the 888 candidates (24.7%) completed the questionnaire, of whom 144 (16.2%) agreed to further investigation. These included 90 of 105 patients with a positive questionnaire and 20 of 115 with a negative questionnaire who underwent colonoscopy and 34 of 115 with a negative questionnaire who underwent sigmoidoscopy. The colonoscopy group included 26 of the 30 patients (86.6%) with a positive family history. Early-stage CRC was diagnosed in three patients (1.36%), all with a positive questionnaire. There were no pathologic findings on sigmoidoscopy. The sensitivity, specificity, and positive and negative predictive values of the questionnaire for identifying subjects with CRC or advanced adenoma were 100.00%, 18.86%, 2.27%, and 100.00%, respectively. In conclusion, using hospital facilities, we initiated a unique CRC screening program for employees. Our method may be applicable in other medical centers for the detection of adenomas and CRCs in the early, curative stages.

Preparation for colonoscopy in hospitalized patients.

Successful colonoscopy depends on good preparation of the colon before the procedure. Inadequate preparation may lead to cancelled or repeat procedures and compromise patient safety, quality of care, and cost effectiveness. The primary aim of this study was to isolate factors that affect preparation success, especially in older, more severely ill, bedridden patients. The secondary aim was to examine the possible differences in preparation quality between ambulatory and hospitalized patients and the impact of a staff educational program on the preparation of hospitalized patients for colonoscopy. The study group included 303 consecutive ambulatory patients and 104 hospitalized patients referred for colonoscopy between January and March 2002, before the department introduced an educational program on colonoscopy preparation, and 310 ambulatory patients and 105 hospitalized patients referred for colonoscopy between January and March 2003. All patients completed an ad hoc questionnaire, and the findings were compared between ambulatory and hospitalized patients and between patients treated before and after the educational program. Polyethylene glycol was used significantly more often for colonoscopy preparation in hospitalized patients than in ambulatory patients (53.1% versus 8.8%; P=.0001). The hospitalized group was characterized by more incomplete or repeated colonoscopies and poorer preparation quality. On multivariate analysis, the variables found to be independent predictors of good preparation were successful patient completion of the preparatory procedure according to instructions, colonoscopy performed for follow-up after polypectomy, and preparation with sodium phosphate. The educational intervention had no impact on the quality of preparation. In conclusion, sodium phosphate preparation and complete adherence to preparation instructions are the most important factors for successful colonoscopy preparation. Current preparatory methods for hospitalized and severely ill patients need to be revised.
