The Impact

Accurately diagnosing urinary tract infections (UTIs) in hospitalized patients remains challenging, requiring correlation of frequently nonspecific symptoms and laboratory findings. Urine cultures (UCs) are often ordered indiscriminately, especially in patients with urinary catheters, despite the Infectious Diseases Society of America guidelines recommending against routine screening for asymptomatic bacteriuria (ASB).1,2 Positive UCs can be difficult for providers to ignore, leading to unnecessary antibiotic treatment of ASB.2,3 Using diagnostic stewardship to limit UCs to situations with a positive urinalysis (UA) can reduce inappropriate UCs since the absence of pyuria suggests the absence of infection.4–6 We assessed the impact of the implementation of a UA with reflex to UC algorithm (“reflex intervention”) on UC ordering practices, diagnostic efficiency, and UTIs using a quasi-experimental design.

Catheter Care

The purpose of this quasi-experimental study was to test the use of a bundled approach of catheter care practices for a 3-month period to reduce the occurrence of catheter-associated urinary tract infections (CAUTIs) in adult critical care patients who had indwelling urinary catheters. Catheter care is completed primarily by nursing staff, however minimal studies exist in the literature that support specific nursing care to reduce the occurrence of CAUTIs. Catheter care practices were investigated and implemented in a bundled approach to determine the impact on reducing CAUTIs in a critical care unit. Though the results were not statistically significant, they were clinically significant with a 50% reduction in CAUTI incidence.

Abstract External urinary collection devices (EUCDs) may reduce indwelling catheter usage and catheter-associated urinary tract infections (CAUTIs). In this retrospective quasi-experimental study, we demonstrated that EUCD implementation in women was associated with significantly decreased indwelling catheter usage and a trend (P = .10) toward decreased CAUTI per 1,000 patient days.

The Impact

Background: Using alternatives to indwelling urinary catheters plays a vital role in reducing catheter-associated urinary tract infections (CAUTIs). We assessed the impact of introducing female external catheters on urinary catheter utilization and CAUTIs. Methods: In a 500-bed academic medical center, female external catheters were implemented on October 1, 2017, with use encouraged for eligible females with urinary incontinence but not meeting other standard indications for urinary catheters. Nurses were educated and trained on female external catheter application and maintenance, and infection prevention staff performed surveillance case reviews with nursing and medical staff. We determined the number of catheter days for both devices based on nursing documentation of device insertion or application, maintenance, and removal. We used the CAUTI and DUR (device utilization ratio) definitions from the CDC NHSN. Our primary outcomes were changes in DUR for both devices 21 months before and 24 months after the intervention in both intensive care units (ICUs) and non-ICU wards. We used a generalized least-squares model to account for temporal autocorrelation and compare the trends before and after the intervention. Our secondary outcome was a reduction in CAUTIs, comparing females to males. Results: In total, there were 346,213 patient days in 35 months. The mean rate of patient days per month increased from 7,436.4 to 7,601.9 after the implementation of female external catheters, with higher catheter days for both urinary catheters (18,040 vs 19,625) and female external catheters (22 vs 12,675). After the intervention, the DUR for female external catheters increased (0 vs 0.07; P < .001) and for urinary catheters the DUR decreased (0.12 vs 0.10; P < .001) (Fig. 1). A reduction in urinary catheter DUR was observed in ICUs (0.29 vs 0.27; P < .001) but not wards (0.08 vs 0.08; P = NS) (Fig. 2). Of the 39 CAUTIs, there was no significant overall change in the rate per 1,000 catheter days (1.22 vs 0.87; P = .27). In females (n = 20 CAUTI), there was a 61% reduction in the CAUTI rate per 1,000 catheter days (0.78 vs 0.31; P = .02), but no significant change in the rate in males (0.44 vs 0.56; P = .64). The CAUTI rate per 1,000 catheter days among females decreased in the ICUs (1.14 vs 0.31; P = .04) but not in wards (0.6 vs 0.33; P = .96). Conclusions: In a setting with a baseline low UC DUR, successful implementation of female external catheters further modestly reduced UC DUR and was associated with a 61% decrease in CAUTI among females in the ICU but not in wards. Further interventions to better identify appropriate patients for female external catheters may improve patient safety and prevent patient harm.Funding: NoneDisclosures: None

Abstract Purpose: Urinary tract infections are the most common infections early after kidney transplantation. The goals of this study were to evaluate our perioperative antibiotic protocol and risk factors for the occurrence of urinary tract and its effect on the early graft function. We evaluated laboratory alterations during episodes of UTI regarding their potential to guide treatment.Methods: Retrospective single-center analysis of all kidney transplant recipients of an academic transplant center between 2015 and 2017.Results: 96 patients were included in the study. Overall, in 22 patients a asymptomatic bacteriuria (ASB) was detected and 33 patients developed a urinary tract infection (UTI). Gram-negative UTIs appeared earlier than gram-positive UTIs. The most common lab findings during UTI were leukocytosis and CRP increase, both more common in gram-negative UTI (p .00 & .03). All complicated UTIs were caused by gram-negative bacteria (p .00). No difference in UTIs was seen between perioperative antibiotic regimens. Patients that suffered from UTIs showed less favorable graft function at discharge (GFR 43 vs 52 ml / min, p .03).Conclusion: UTIs are associated with worse graft functions while ASBs are not. Whether UTIs are caused by or lead to decreased graft function is still unclear. Proper gram-negative coverage is needed in cases of complicated UTIs or severe laboratory findings. Perioperative antibiotic regimens appear to have no beneficial influence on the incidence of UTIs.

Abstract Background One of the most readily available and cost effective tests in the diagnosis of urinary tract infections (UTI) is the urinalysis. Problems arise when antibiotic treatment is initiated in a patient who does not display typical signs and symptoms of UTI and for whom a urinalysis was obtained for other reasons. Methods This was a retrospective observational study carried out on 1000 patients with positive urine nitrite. Medical records were identified with subsequent analysis of urine culture and symptomatology. Recorded and analyzed data included: age, sex, location (emergency room (ER) or hospital ward), findings on urinalysis (pH, presence of leukocyte esterase(LE), epithelial cells, bacteria, and white blood cells (WBCs)) and antibiotic treatment. Results Of these 1000 patients with positive nitrite, we excluded 815 patients (81 had missing data, 466 met exclusion criteria and 268 had symptomatic UTI). 185 were found to not have any symptoms of a UTI. Inappropriate antibiotic treatment occurred in 108/185 patients (58.4%) and was significantly associated with greater amounts of bacteria and WBCs in the urinalyses (P = 0.008 and P = 0.029, respectively). It was also significantly more likely to occur in the ER than the hospital wards (92/147 treated in the ER vs. 16/37 treated on the hospital wards, P = 0.033). There was no significant association between antibiotic treatment and age, sex, urine pH, urine LE, and urine epithelial cell amounts (P &gt; 0.05). Urine cultures were not obtained in 69.7% of patients. A positive urine culture was significantly associated with inappropriate antibiotic treatment (P = 0.0006). The two most common presenting complaints were psychiatric complaints (21.6%) and vaginal bleeding (14.6%). Conclusion Urinalysis can be an invaluable diagnostic tool, but must be used and interpreted appropriately. There is a misperception that pyuria with bacteriuria defines UTI. However, positive results on a urinalysis alone in an asymptomatic patient is not enough to diagnose a UTI, and antibiotic treatment is only indicated in specific circumstances as outlined by IDSA guidelines for the treatment of asymptomatic bacteriuria. Further education targeting appropriate interpretation of urinalyses and IDSA guidelines is needed to decrease the unnecessary use of antibiotics. Disclosures All authors: No reported disclosures.

Background: Urinary tract infections (UTI) are one of the most common hospital-acquired infections with 80% as a result of urinary catheterisation. Aim/Objective: This study examined the impact of a simple intervention consisting of a daily chart reminder in patients with indwelling urinary catheters (IUC) on the duration of catheter use and the incidence of catheter-associated UTIs (CAUTIs). Methods: The trial used a prospective pretest–post-test design with a control group over a six-month period conducted on two medical units of a community teaching hospital. We included all patients admitted to two medical units between 1 June and 30 November 2016 who had an IUC inserted at the study site. During the intervention phase, a sticker was placed in the charts of patients with urinary catheters reminding physicians to assess for catheter removal if not clinically necessary. Results: A total of 195 patients participated in this study (112 control unit, 83 intervention unit). There was a decrease in the duration of IUC use on the intervention unit from 11.7 days to 7.5 days ( P = 0.0028). There was a decrease in repeated catheterisation from 11.1% to 2.1% ( P = 0.0882), and CAUTIs from 17.5% to 4.6% ( P = 0.0552) but this did not reach statistical significance. Discussion: The implementation of a daily IUC reminder sticker in patient charts was associated with a significant reduction in the mean duration of indwelling catheter use with a trend towards a reduction in the frequency of repeated urinary catheterisation and rate of CAUTIs.

Abstract Background It has been postulated that the COVID-19 pandemic would increase the overall catheter-associated urinary tract infections (CAUTI) risk in part due to higher acuity, increased indwelling urinary catheter (IUC) utilization, longer length of stay, changes in infection prevention practices due to staffing shortages. However, reported data are limited. The goal of this study was to evaluate the impact of the COVID-19 pandemic on our CAUTI rates. Methods This was a retrospective cross-sectional study comparing CAUTI rate per 1,000 indwelling urinary catheter (IUC) days, urine culture (UC) utilization rate per 1,000 IUC days, IUC utilization rate per 1,000 patient days, Standardized Infection Ratio (SIR) and Standardized Utilization Ratio (SUR) in the pre-COVID-19 period from January 1, 2019 to December 31, 2019 to the COVID-19 period from April 1, 2020 to March 31, 2021 at an 877-bed tertiary care hospital in Detroit, Michigan. CAUTI, UC utilization and IUC utilization rate were extracted from the electronic medical record (Epic™ Bugsy). SIR and SUR data were extracted from National Healthcare Safety Network (NHSN). Results The average CAUTI rate per 1,000 IUC days decreased from 0.99 pre-COVID-19 to 0.64 during COVID-19, yielding a 35% reduction. The UC order rate per 1,000 IUC days decreased from 19.19 to 18.83 with only 2% reduction. However, IUC utilization rate increased by 55% from 0.184 to 0.286. The SIR decreased from 0.483 to 0.337 with a 30% reduction, although this was not statistically significant ((P-value 0.283). The overall SUR decreased significantly from 0.806 to 0.762 (P-value &lt; 0.001). Figure 2 is a control chart of the CAUTI rate from July 2019 to April 2021. Figure 1. CAUTI, indwelling urinary catheter and urine culture utilization rates pre-and during COVID-19 pandemic. Figure 2. CAUTI control chart pre-and during COVID-19 pandemic. Conclusion Although the IUC utilization increased during the COVID-19 pandemic, CAUTI rate, SIR and SUR decreased and UC orders remained unchanged. Thus, the pandemic did not have a negative impact on our CAUTI rates. Disclosures All Authors: No reported disclosures

Abstract Background In the acute care setting, urinary tract infections (UTIs) may be over diagnosed in up to 40% of cases. In most scenarios, asymptomatic bacteriuria (ASB) is not an indication for antibiotic therapy; inappropriate therapy is associated with a higher incidence of antibiotic-resistant bacteria and adverse drug reactions. Limiting inappropriate collection of urine cultures may decrease unnecessary treatment of ASB. The objective of this study is to assess the impact of a urine culture best practice advisory (BPA) on collection of unnecessary urine cultures. Methods This retrospective, observational, single-center study included adult inpatients with an order for urinalysis/urine culture. Those who were pregnant, had a concomitant infection other than UTI and/or were taking antimicrobials for a non-UTI indication, and were undergoing urological procedures were excluded. Duplicate urine culture collections and/or admissions were excluded. Incorporation of a BPA into computerized provider order entry, allowing providers to assess need and document indication for urine culture collection, was implemented on July 2019. The following clinical outcomes were assessed: number of unnecessary urine cultures collected, number of antibiotic treatments, and antibiotic-associated adverse reactions. Results Two hundred met criteria for inclusion; 96 in the pre-BPA group (Aug – Oct 2018) and 104 in the post-BPA group (Aug – Oct 2019). Seventy-four (37%) were male and the mean age was 64 and 70 years (p=0.249), respectively. The Charlson Comorbidity Index (CCI) was similar between groups (4 vs. 5, p=0.162) and majority were admitted to a general medical ward (94.5%). Seventy patients (72.9%) in the pre-BPA group and 47 (51.6%) in the post-BPA group had inappropriately ordered urinalysis/urine cultures (OR 0.40; 95% CI 0.22-0.73; p=0.003). Of these patients, 15 (21.4%) and 9 (19.1%) from the pre- and post-BPA groups, respectively, were treated (p=0.077). Among those treated, only two adverse drug reactions were reported. Conclusion Implementation of a BPA significantly reduced the number of inappropriate urinalysis/urine culture orders. There was a trend towards decreased antibiotic use for ASB. Future studies are warranted to assess sustainability of these results. Disclosures All Authors: No reported disclosures
