BACKGROUND: Drug resistance indexes (DRIs) quantify the cumulative impact of antimicrobial resistance on the likelihood that a given pathogen will be susceptible to antimicrobial therapy.OBJECTIVE: To derive a DRI for community urinary tract infections caused byEscherichia coliin British Columbia for the years 2007 to 2010, and to examine trends over time and across patient characteristics.METHODS: Indication-specific utilization data were obtained from BC PharmaNet for outpatient antimicrobial prescriptions linked to diagnostic information from physician payment files. Resistance data forE coliurinary isolates were obtained from BC Biomedical Laboratories (now part of LifeLabs Medical Laboratory Services). DRIs were derived by multiplying the rate of resistance to a specific antimicrobial by the proportional rate of utilization for that drug class and aggregating across drug classes. Higher index values indicate more resistance.RESULTS: Adaptive-use DRIs remained stable over time at approximately 18% (95% CI 17% to 18%) among adults ≥15 years of age and approximately 28% (95% CI 26% to 31%) among children <15 years of age. Similar results were observed when proportional drug use was restricted to the baseline year (ie, a static-use model). Trends according to age group suggest a U-shaped distribution, with the highest DRIs occurring among children <10 years of age and adults ≥65 years of age. Males had consistently higher DRIs than females for all age groups.CONCLUSIONS: The stable trend in adaptive-use DRIs over time suggests that clinicians are adapting their prescribing practices for urinary tract infections to local resistance patterns. Results according to age group reveal a higher probability of resistance to initial therapy among young children and elderly individuals.

Introduction: Surveillance of antimicrobial resistance is essential in establishing treatment guidelines for urinary tract infections. The aim of this pilot study was to analyse resistance rates of pathogens, across different demographics and determine whether adjustments in empiric therapy should be considered for different age and gender groups. Methodology: A 5-year retrospective study included 256 patients hospitalised, under the initial diagnosis of Fever of Unknown Origin who were then subsequently diagnosed with a urinary tract infection at the Clinic for Infectious and Tropical Diseases, Clinical Centre of Serbia. Patients were evaluated using demographic, clinical, and antimicrobial resistance data with appropriate statistical analysis including ANOVA significance testing, univariate, and multivariate analysis. Results: Resistance rates were above the threshold of 20% for the majority of the antimicrobials tested, the only exception being carbapenems. Amikacin, cefepime, and norfloxacin were agents that could be effectively used as empiric therapy in younger adults with resistance rates of 4.2, 8.0, and 10.0%, respectively. Moderate resistance rates of 17.4% for amikacin and 19.1% for cefepime were observed in the age group 35-64 years. High resistance rates were observed for all antimicrobials among patients 65 years and over. Among male patients, resistance rates to most antimicrobials were high. In female patients, amikacin and cefepime had resistance rates less than 20%. Younger age presented as a negative risk factor for infection by a multi-drug resistant pathogen. Conclusion: Age and gender demonstrated to be significant factors for determining proper empiric therapy; large-scale studies from Serbia are needed to solidify these findings.

Abstract Background Outpatient therapies for urinary tract infections (UTIs) are becoming limited due to antimicrobial resistance. The purpose of this paper is to report how the incidence of hospitalizations for UTIs have varied over time in both men and women and across age groups. We also explore how the severity for UTI hospitalizations has changed and describe the seasonality of UTI hospitalizations. Methods Using the Nationwide Inpatient Sample, we compute a time-series of UTI incidence and subdivide the series by age and sex. We fit a collection of time-series models to explore how the trend and seasonal intensity varies by age and sex. We modeled changes in severity using regression with available confounders. Results In 2011, there were approximately 400000 hospitalizations for UTIs with an estimated cost of $2.8 billion. Incidence increased by 52% between 1998 and 2011. The rate of increase was larger among both women and older patients. We found that the seasonal intensity (summer peaks and winter troughs) increased over time among women while decreasing among men. For both men and women, seasonality decreased with advancing age. Relative to controls and adjusted for demographics, we found that costs among UTI patients grew more slowly, patients left the hospital earlier, and patients had lower odds of death. Conclusions Incidence of UTI hospitalization is increasing and is seasonal, peaking in the summer. However, the severity of UTI admissions seems to be decreasing, indicating that patients previously treated as outpatients may now be admitted to the hospital due to increasing antimicrobial resistance.

Background Antimicrobial resistance in community-associated infections is an increasing worldwide concern. In low-to-middle income countries, over-the-counter (OTC) sales of antimicrobials without medical prescription have been blamed for increasing consumption and resistance. We studied the impact of restriction of OTC sales of antimicrobials in Brazil (instituted in October 2010) on resistance trends of Escherichia coli from community-onset urinary tract infections. Methods We analyzed monthly resistance trend of Escherichia coli from community-onset urinary tract infections from 2005 through 2018. The data were submitted to interrupted time series analysis in both linear and Poisson regression models. Results We found impact on cefazolin (p<0.001) and amikacin (p<0.001) resistance as immediate impact of the intervention, and no beneficial impact on resistance to ciprofloxacin, ceftriaxone or sulfamethoxazole-trimethoprim. Conclusion At the present study, we found that OTC sales restriction did not generally impact on antimicrobial resistance.

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
