The objective of this investigation was to determine the frequency of and predictors for inadequate barium enemas in the frail elderly.
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.
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).
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.
本研究旨在确定体弱老年人钡剂灌肠检查不充分的频率及其预测因素。
回顾性分析171例接受钡剂灌肠检查的老年住院患者（平均年龄 = 85.3岁）的医学和放射学记录。主要研究结果是钡剂灌肠检查结果书面总结中放射科医生关于检查是否充分的报告。
171项检查中有88项（51.5%）被认为不充分，其中肠道准备不佳是89.7%的不充分检查的主要或促成因素。在各种人口统计学和临床因素中，只有长期使用泻药和/或灌肠剂与检查不充分相关（比值比 = 7.0；95%置信区间2.7至18.0）。
这些结果表明，高龄患者钡剂灌肠检查不充分的频率非常高，提示该患者群体需要改进肠道准备方法，尤其是长期使用泻药和灌肠剂的患者。
