| Summary: | 碩士 === 高雄醫學大學 === 護理學研究所 === 101 === Catheter associated urinary tract infection is one of the most common nosocomial infections. The catheterization is often performed on the patients if they are under poor conditions in intensive care units (ICU). However, the incidence of catheter-associated urinary tract infection (CAUTI) in the intensive care units is up to 5.1 ‰. This study was attempted to explore the value of urine pH and fluid intake on the occurrence of urinary tract infection (UTI) for the patients with catheterization in ICU.
The longitudinal historical cohort design was adopted for this study, and the purposive sampling was selected for the patients with indwelling urinary catheter and were hospitalized in ICU at a medical center in Kaohsiung. Sixty-one patients participated in this study. The measurement tools include the questionnaires of demographic and disease characteristics, urinary tract infection symptoms questionnaire, intake and output record sheet, urine pH strip and pH test meter. The tests were started after the patients agree to participant the study until they were discharged from the ICU or transferred to the ward. The data were analyzed using chi-square and t-test for descriptive statistics and generalized estimating equation(GEE) for inferential statistics.
The results showed that there were significant differences between the first and second urine specific gravity, urine osmolarity, the second urine appearance with turbid and the second test of bacteriuria. It was find the urine appearance with turbid could be used as a predictor of bacteriuria based on the result of GEE. Thus, the urine appearance with or without turbid is recommended to be the indicator of bacteriuria for the early detection of bacteriuria.
