Antimicrobial resistance in urosepsis: outcomes from the multinational, multicenter global prevalence of infections in urology (GPIU) study 2003–2013
Objective Primary objective was to identify the (1) relationship of clinical severity of urosepsis with the pathogen spectrum and resistance and (2) appropriateness of using the pathogen spectrum and resistance rates of health-care-associated urinary tract infections (HAUTI) as representative of urosepsis. The secondary objective was to provide an overview of the pathogens and their resistance profile in patients with urosepsis. Population and Methods A point prevalence study carried out in 70 countries (2003–2013). Population studied included; 408 individuals with microbiologically proven urosepsis, 1606 individuals with microbiological proof of HAUTI and 27,542 individuals hospitalised in urology wards. Main outcomes are pathogens and resistance identified in HAUTIs and urosepsis including its clinical severity. A statistical model that included demographic factors (study year, geographical location, hospital setting) was used for analysis. Results Amongst urology practices, the prevalence of microbiologically proven HAUTI and urosepsis was 5.8 and 1.5 %, respectively. Frequent pathogens in urosepsis were E. coli (43 %), Enterococcus spp. (11 %), P. aeruginosa (10 %) and Klebsiella spp . (10 %). Resistance to commonly prescribed antibiotics was high and rates ranged from 8 % (imipenem) to 62 % (aminopenicillin/β lactamase inhibitors); 45 % of Enterobacteriaceae and 21 % of P. aeruginosa were multidrug-resistant. Resistance rates in urosepsis were higher than in other clinical diagnosis of HAUTI (Likelihood ratio <0.05). Conclusions It is not appropriate to use the pathogen spectrum and resistance rates of other HAUTIs as representative of urosepsis to decide on empirical treatment of urosepsis. Resistance rates in urosepsis are high, and precautions should be made to avoid further increase.
Antibiotic resistance, hospitalizations, and mortality related to prostate biopsy: first report from the Norwegian Patient Registry
BackgroundA 68-year-old man died of cerebral arterial embolism 6 days after transrectal prostate biopsy with a single p.o. dose of trimethoprim sulfamethoxazole (TMP-SMX) as prophylaxis. The case precipitated analysis of local antibiotic resistance and complication rates.Materials and methodsData on E. coli resistance from Oslo University Hospital and national data on hospitalizations and mortality after biopsy were retrieved from local microbiology files and the Norwegian Patient Registry (NPR) 2011–2017.ResultsUrine E. coli resistance against TMP-SMX increased from 35% in 2013 to more than 60% in 2015. For ciprofloxacin, the resistance increased from 15% in 2013 to about 45% in 2016. The highest annual E. coli resistance in blood cultures for TMP-SMX and ciprofloxacin was 37% and 28%, respectively. 10% of patients were hospitalized with a diagnosis of infection within the first 60 days after biopsy and there was a relative increase in mortality rate of 261% within the first 30 days. Due to the severity of the figures, the story and the NPR data were published in Norway’s leading newspaper and were succeeded by a series of chronicles and commentaries.ConclusionsSeveral critical points of the biopsy procedure were not performed according to current standards. We believe that the patient might have died of septic embolism after biopsy. As a result of the findings and the debate, local practice was changed from transrectal to transperineal prostate biopsies.
Comparison of the Efficacy of Percutaneous Microwave Ablation Therapy versus Laparoscopic Partial Nephrectomy for Early-Stage Renal Tumors
This study aimed to compare the efficacy of percutaneous microwave ablation therapy (MWAT) and laparoscopic partial nephrectomy (LPN) in early-stage renal cell carcinoma (RCC) classified as T1a; a retrospective analysis was conducted on patients treated between January 2017 and November 2023. Oncological outcomes, radiological recurrence, length of stay (LOS), and costs were evaluated. The study included 110 patients, with no significant differences between the two groups regarding residual tumors, local tumor progression, and disease-free survival rates (p > 0.05). The LPN group showed significantly lower pre/postoperative serum urea and creatinine and higher estimated glomerular filtration rate values, whereas the MWA group experienced significantly lower mean costs, complication rates, LOS in the hospital, and procedure durations (p ≤ 0.05). However, post-procedure residual tumors and local tumor progression rates did not differ significantly between the LPN and MWAT groups (p > 0.05). MWAT is as effective as LPN for T1a RCC lesions. In addition, MWAT has lower costs than LPN and is a cost-effective treatment method. Therefore, MWAT minimizes hospital stay and complications and since the oncological results are similar to LPN, it might be considered as the first choice of treatment in young patients.
Condition-specific surveillance in health care-associated urinary tract infections as a strategy to improve empirical antibiotic treatment: an epidemiological modelling study
BackgroundHealth care-associated urinary tract infection (HAUTI) consists of unique conditions (cystitis, pyelonephritis and urosepsis). These conditions could have different pathogen diversity and antibiotic resistance impacting on the empirical antibiotic choices. The aim of this study is to compare the estimated chances of coverage of empirical antibiotics between conditions (cystitis, pyelonephritis and urosepsis) in urology departments from Europe.MethodsA mathematical modelling based on antibiotic susceptibility data from a point prevalence study was carried. Data were obtained for HAUTI patients from multiple urology departments in Europe from 2006 to 2017. The primary outcome of the study is the Bayesian weighted incidence syndromic antibiogram (WISCA) and Bayesian factor. Bayesian WISCA is the estimated chance of an antibiotic to cover the causative pathogens when used for first-line empirical treatment. Bayesian factor is used to compare if HAUTI conditions did or did not impact on empirical antibiotic choices.ResultsBayesian WISCA of antibiotics in European urology departments from 2006 to 2017 ranged between 0.07 (cystitis, 2006, Amoxicillin) to 0.89 (pyelonephritis, 2009, Imipenem). Bayesian WISCA estimates were lowest in urosepsis. Clinical infective conditions had an impact on the Bayesian WISCA estimates (Bayesian factor > 3 in 81% of studied antibiotics). The main limitation of the study is the lack of local data.ConclusionsOur estimates illustrate that antibiotic choices can be different between HAUTI conditions. Findings can improve empirical antibiotic selection towards a personalized approach but should be validated in local surveillance studies.
The Global Prevalence of Infections in Urology Study: A Long-Term, Worldwide Surveillance Study on Urological Infections
The Global Prevalence of Infections in Urology (GPIU) study is a worldwide-performed point prevalence study intended to create surveillance data on antibiotic resistance, type of urogenital infections, risk factors and data on antibiotic consumption, specifically in patients at urological departments with healthcare-associated urogenital infections (HAUTI). Investigators registered data through a web-based application (http://gpiu.esiu.org/). Data collection includes the practice and characteristics of the hospital and urology ward. On a certain day in November, each year, all urological patients present in the urological department at 8:00 a.m. are screened for HAUTI encompassing their full hospital course from admission to discharge. Apart from the GPIU main study, several side studies are taking place, dealing with transurethral resection of the prostate, prostate biopsy, as well as urosepsis. The GPIU study has been annually performed since 2003. Eight-hundred fifty-six urology units from 70 countries have participated so far, including 27,542 patients. A proxy for antibiotic consumption is reflected by the application rates used for antibiotic prophylaxis for urological interventions. Resistance rates of most uropathogens against antibiotics were high, especially with a note of multidrug resistance. The severity of HAUTI is also increasing, 25% being urosepsis in recent years.
Preoperative assessment of the patient and risk factors for infectious complications and tentative classification of surgical field contamination of urological procedures
Purpose To assess the patient and identify the risk factors for infectious complications in conjunction with urological procedures and suggest a model for classification of the procedures. Method Review of literature, critical analysis of data and tentative model for reducing infectious complications. Results Risk factors are bound to the patient and to the procedure itself and are associated with the environment where the healthcare is provided. Assuming a clean environment and sterile operation field, a five-level assessment ladder related to the patient and type of surgery is useful, considering: (1) the ASA score, (2) the general risk factors, (3) the individual endogenous and exogenous risk factors, (4) the class of surgery and the potential bacterial contamination burden and (5) the level of severity and difficulty of the surgical intervention. A cumulative approach will identify the level of risk for each patient and define preventive measures, such as the type of antibiotic prophylaxis or therapeutic measures before surgery. There are data suggesting that the higher the ASA score, the higher is the risk of infectious complication. Age, dysfunction of the immune system, hypo-albuminaemia/malnutrition and overweight, uncontrolled blood glucose level and smoking are independent general risk factors, whilst bacteriuria, indwelling catheter treatment, urinary tract stone disease, urinary tract obstruction and a history of urogenital infection are specific urological risk factors. There is inconclusive evidence for most other reported risk factors. The level of contamination of the surgical field is of utmost importance as are the procedure-related factors, and the sum of these have to be reflected on for the subsequent perioperative management of the patient. Conclusions It is essential to identify and control risk factors to minimize infectious complications in conjunction with urological procedures. Our knowledge is limited and clinical research and quality registries analysing risk factors must be undertaken. We propose a working basis for assessment of patients’ risk factors and classification of urological procedures.
Healthcare-associated urinary tract infections in hospitalized urological patients—a global perspective: results from the GPIU studies 2003–2010
Introduction European Section for Infections in Urology has been conducting an annual prevalence survey investigating various aspects of healthcare-associated urinary tract infections (HAUTI) since 2003. Material and Methods The data on various clinical categories of HAUTI, the contamination status of HAUTI patients who underwent any urological intervention with regard to microorganisms isolated, resistance status and antibiotics used to treat HAUTI will be presented. Results Of a total of 19,756 patients screened, 1,866 patients had HAUTI (9.4 %); 1,313 males (70.4 %) and 553 (29.6 %) females. Mean age was 59.9 ± 18.2. Asymptomatic bacteriuria (ASB) and cystitis were the most frequent clinical diagnoses representing 27.0 and 26 % of all HAUTI, respectively. Echerichia coli was found to be the most frequent uropathogen (544 of 1,371 isolates) (39.7 %). Fluoroquinolones were preferred in 26.6 % of cases followed by cephalosporins (23.3 %), aminoglycosides (14.1 %) and penicillins (13.8 %). High global resistance rates to ciprofloxacin (>50 %), cephalosporins (35–50 %) and penicillins (50 %) were found in the GPIU studies 2003–2010. Discussion We showed that around 10 % of hospitalized urological patients are at risk to develop HAUTI often caused by multiresistant uropathogens. Increased antibiotic use often with broad-spectrum antimicrobials will inevitably be followed by increasing bacterial resistance. To interrupt such a vicious cycle, our results suggest (1) there is still room for improvement in surgical prophylaxis in terms of limiting exposure to antibiotics and (2) far too many patients with ASB are being treated which shows that the new proposal of classification should be adopted where ABS is regarded as colonization and not as an infection to be treated.
Urosepsis 30-day mortality, morbidity, and their risk factors: SERPENS study, a prospective, observational multi-center study
Purpose To provide a descriptive report of mortality and morbidity in the first 30 days of diagnosis of urosepsis. Secondary aim is to identify risk factors of unfavourable outcomes. Methods Prospective observational multicentre cohort study conducted from September 2014 to November 2018 in European hospitals. Adult patients (≥ 18 years) diagnosed with acute urosepsis according to Sepsis-2 criteria with confirmed microbiological infection were included. Outcomes were classified in one of four health states: death, multiple organ failure, single organ failure, and recovery at day 30 from onset of urosepsis. Descriptive statistics and ordinal logistic regression analysis was performed. Results Three hundred and fifty four patients were recruited, and 30-day mortality rate was 2.8%, rising to 4.6% for severe sepsis. All patients who died had a SOFA score of ≥ 2 at diagnosis. Upon initial diagnosis, 79% ( n  = 281) of patients presented with OF. Within 30 days, an additional 5% developed OF, resulting in a total of 84% affected. Charlson score (OR 1.14 CI 1.01–1.28), patients with respiratory failure at baseline (OR 2.35, CI 1.32–4.21), ICU admission within the past 12 months (OR 2.05, CI 1.00–4.19), obstruction causative of urosepsis (OR 1.76, CI 1.02–3.05), urosepsis with multi-drug-resistant(MDR) pathogens (OR 2.01, CI 1.15–3.53), and SOFA baseline score ≥ 2 (OR 2.74, CI 1.49–5.07) are significantly associated with day 30 outcomes (OF and death). Conclusions Impact of comorbidities and MDR pathogens on outcomes highlights the existence of a distinct group of patients who are prone to mortality and morbidity. These findings underscore the need for the development of pragmatic classifications to better assess the severity of UTIs and guide management strategies.
