Urinary incontinence is common in the increasing numbers of aged people and is often the precipitating factor for nursing home admission. Recalcitrant incontinence may be managed by urethral catheters. In this study of a random stratified sample of Maryland nursing homes (4259 patients), we found that the daily prevalence of urethral catheter use in Maryland nursing homes was 7.5%. More than 80% of urethral catheter users were women. Among men, we found equal prevalences of urethral and condom catheter use. Previous studies have demonstrated long-term use of urethral catheters to be associated with almost universal bacteriuria of a polymicrobial and dynamic nature. Combining these data suggests that long-term catheter-associated bacteriuria is the most common infection in American health care facilities.
尿失禁在日益增多的老年人中很常见，且常常是导致入住养老院的诱发因素。顽固性尿失禁可用尿道导管处理。在这项对马里兰州养老院随机分层抽样（4259名患者）的研究中，我们发现马里兰州养老院中使用尿道导管的日患病率为7.5%。超过80%的尿道导管使用者为女性。在男性中，我们发现尿道导管和避孕套导管的使用患病率相同。先前的研究表明，长期使用尿道导管与几乎普遍存在的具有多种微生物且动态变化性质的菌尿症有关。综合这些数据表明，长期导管相关性菌尿症是美国医疗保健机构中最常见的感染。
