Barium enemas in the frail elderly.PURPOSE: The objective of this investigation was to determine the frequency of and predictors for inadequate barium enemas in the frail elderly. PATIENTS AND METHODS: The medical and radiologic records of 171 elderly institutionalized patients (mean age = 85.3 years), who underwent barium enema examinations, were retrospectively reviewed. The study outcome of primary interest was the radiologist's report of the adequacy of examination as indicated in the written summary of the results of the barium enema procedure. RESULTS: Eighty-eight (51.5%) of the 171 studies were deemed inadequate, with poor bowel preparation a primary or contributing factor in 89.7% of the inadequate studies. Among a variety of demographic and clinical factors, only long-term laxative and/or cathartic use was associated with an inadequate study (odds ratio = 7.0; 95% confidence interval 2.7 to 18.0). CONCLUSION: These results demonstrate a very high frequency of inadequate barium enema examinations in the very old and suggest a need for improved methods of bowel preparation in this patient population, especially in those who are long-term users of laxatives and cathartics.

Colorectal cancer screening in Massachusetts: measuring compliance with current guidelinesCONTEXT: Professional organizations have published guidelines for colorectal cancer screening. Defining which patients are currently, or should be, screened is an important clinical and public health issue. OBJECTIVE: To document the prevalence of colorectal cancer screening and profile the tests patients have had. DESIGN/POPULATION: A random-digit telephone survey of Massachusetts adults, 50 years of age and older. OUTCOME MEASURES: Percentage of persons ever and currently tested by fecal occult blood tests, flexible sigmoidoscopy, barium enema, colonoscopy, or some combination of these tests. RESULTS: Sixty-five percent of those contacted agreed to the telephone interview. Approximately 29% of the 1119 respondents had never had any currently accepted test, including 10% who reported having only a fecal occult blood test done in a provider's office and 19% who reported having no tests. At least 51% were currently tested by one or more tests for screening, diagnosis, or both. Another 10% were possibly current by colonoscopy or barium enema, both of which can be ordered for screening but are more commonly used to evaluate a problem, such as rectal bleeding, or for surveillance after identification of a polyp or other abnormality. An additional 11% had been tested at some point but were not current according to guidelines. CONCLUSIONS: Accurate assessment of rates of colorectal cancer screening is complex because of the multiple acceptable screening methods, the fact that patients may be tested for screening or diagnostic purposes, and the lack of adequate systems for tracking such testing. For accurate measurement, all methods must be assessed regardless of whether tests were ordered for screening, diagnosis, or surveillance.
