Diseases of the colon and rectum

The introduction of reimbursement for screening colonoscopy in Germany more than one year ago raised concerns that the consequent workload might lead to underuse of diagnostic colonoscopy for symptomatic patients. Available appropriateness criteria for diagnostic colonoscopy have been rarely tested in a realistic outpatient setting. This study was designed to test current appropriateness criteria for diagnostic colonoscopy to better select patients and potentially provide more capacity for screening cases. Secondary goals were yield and quality control in both the diagnostic and screening cases. ⋯ Currently used appropriateness criteria for diagnostic colonoscopy increase the yield of relevant findings but lead to a miss rate for relevant findings in the range of 10 to 15 percent. Simple selection criteria based on age and symptoms could be more suitable and should be tested in a larger group of patients.
