Efficacy of XXXX cleansing in reducing contamination of bagged urine specimens.

To determine the effectiveness of precleansing with @entity5164 - @entity14942 in reducing the contamination rate of bagged urine specimens, 62 @entity1 admitted to a @entity1 's hospital were randomly assigned to either receive (32 @entity1 ) or not receive (30) cleansing before bag application. Perimeatal swabs were taken before bag application and, in the treated group, after cleansing. Of the specimens from the treated group 69% were found to be contaminated, compared with 73% of those from the no-cleansing group. @entity1216 was ineffective in eliminating the perimeatal flora in 75% of the @entity1 . The same organisms were present on the perimeatal swab and in the urine specimen in 95% of the @entity1 in the treated group and 96% of those in the no-cleansing group. To estimate the contamination rate of urine specimens routinely cultured in the laboratory, 200 consecutive specimens (142 midstream and 58 bagged) were cultured. The contamination rate of the midstream urine specimens was 15%, compared with 66% for the bagged specimens. The cost of laboratory processing of contaminated bagged urine specimens at the hospital in 1983 may have been as high as  13 365. @entity1216 cleansing does not appear to be cost-effective. Further randomized controlled studies are needed to evaluate the effectiveness of other cleansing agents in reducing the contamination rate of bagged urine specimens.
