The significance of bacteriuria or urinary tract infection in incontinent residents and the association with fluid intake has not been explored fully.
The aim of this study was to test whether or not increasing fluid intake changed the occurrence of bacteriuria in incontinent residents in nursing homes between baseline and 6-week follow-up.
A quasiexperimental study with pretest and posttest design was conducted in six nursing homes in Kaohsiung, Taiwan. A 6-week increasing fluid regimen (n = 44) was tested against the maintenance group (n = 30). The intake and output checklist was used to record residents' fluid intake, and bacteriuria was confirmed by a positive urine culture.
The prevalence of asymptomatic bacteriuria was 29.7% at baseline and 17.6% at the 6-week follow-up. Despite higher percentage of reduction in bacteriuria noted in the increasing group (15.9% vs. 6.7%), increasing fluid intake to reduce the occurrence of bacteriuria was not statistically supported.
Adequate amount of fluid intake, participants' characteristics, and components of a fluid regimen are major cautions in interpreting the preliminary results. Fluid intake could be the least harmful and the cheapest method to reduce susceptibility for bacteriuria. Combining behavioral approaches such as improving access to fluid or scheduled toileting may be beneficial in reducing the occurrence of bacteriuria in incontinent elders in nursing homes.
在失禁居民中，菌尿或尿路感染的意义以及与液体摄入的关系尚未得到充分探讨。
本研究旨在测试增加液体摄入是否会改变养老院中失禁居民在基线和 6 周随访期间发生菌尿的情况。
在台湾高雄的 6 家养老院中进行了一项准实验研究，采用前后测试设计。将 6 周的增加液体方案（n = 44）与维持组（n = 30）进行比较。使用摄入量和输出量检查表记录居民的液体摄入量，并用阳性尿液培养来确认菌尿。
基线时无症状菌尿的患病率为 29.7%，6 周随访时为 17.6%。尽管增加组的菌尿减少百分比更高（15.9%比 6.7%），但增加液体摄入以减少菌尿的发生并没有得到统计学支持。
在解释初步结果时，需要注意适当的液体摄入量、参与者的特征和液体方案的组成部分。液体摄入可能是减少菌尿易感性的最无害和最便宜的方法。结合改善液体获取或定时如厕等行为方法可能有助于减少养老院中失禁老年人的菌尿发生。
