1151. A Comparison of Periurethral Cleaning Between Normal Saline and Savlon Solutions Before Indwelling Urinary Catheterization in Reducing Catheter-Associated Bacteriuria: A Randomized Controlled Study

BACKGROUND: Catheter-associated urinary tract infection (CAUTI) is one of the most common nosocomial infections. To date, there have been no randomized controlled studies to recommend the most appropriate antiseptic solution for periurethral cleaning before indwelling urinary catheterization. This study was aimed to compare normal saline solution (NSS) and Savlon solution for periurethral cleaning before indwelling urinary catheterization in reducing catheter-associated bacteriuria. METHODS: A randomized controlled, noninferiority, cross-over study to determine the incidence of significant bacteriuria (SB) on day 5 after Foley catheterization, using 2 different solutions for periurethral cleaning (NSS and Savlon solutions), was carried out in all adult patients admitted in the 2 medical intensive care units (ICUs), 1 surgical ICU, 2 neurosurgical ICUs, 4 medical wards, 4 surgical wards and 1 emergency room (ER) of King Chulalongkorn Memorial Hospital, Thailand, from June 2018 to March 2019. The acceptable prespecified noninferiority margin was set to be 10%. Each solution was used alternately every 3 months in each unit. Urine culture was collected on day 1, 3, and 5 of Foley catheter. RESULTS: During the study period, there were 207 and 160 patients in the NSS and Savlon groups, respectively. 202 (55%) patients had received Foley catheterization in the emergency room. There were no significant differences in the indication, the current illness, and preexisting condition between the 2 groups. The overall incidence of SB on day 3 and 5 after catheterization was 4% and 8.2%. The incidence of CAUTI was 3.43/1,000 catheter-day. The median duration of catheterization was 5 (IQR 3, 7) days. On day 5 after catheterization, noninferiority was demonstrated for the incidence of SB with an adjusted difference of 4 (95% CI of the difference: −2.1% to 8.9%, P = 0.05). Regarding the incidence of CAUTI, there was no significant difference between the 2 groups. CONCLUSION: To the best of our knowledge, our study was the first randomized controlled study to compare the 2 solutions for periurethral cleaning before indwelling urinary catheterization in different departments. This study demonstrates the noninferiority of NSS to Savlon solution in reducing the incidence of SB. DISCLOSURES: All authors: No reported disclosures.
