Overtreatment of Asymptomatic Candiduria among Hospitalized Patients: a Multi-institutional Study.

ABSTRACT: Candiduria is common in hospitalized patients, and asymptomatic candiduria contributes to antifungal overuse. The guidelines for management of asymptomatic candiduria do not recommend antifungal use, but rather the elimination of predisposing factors. It is unknown whether these recommendations are being followed. The primary objective of this study was to characterize candiduria management among hospitalized patients. This was a retrospective cohort study of a random sample of 305 hospitalized patients with candiduria at four U.S. medical centers from January 2010 to December 2013. Patients were classified as asymptomatic or symptomatic based on established criteria, and data were collected by chart review. Infectious Diseases Society of America (IDSA) treatment guideline adherence and its association with clinical outcomes, including candiduria recurrence (short- and long-term) and 30-day readmission, were assessed. Eighty percent of patients were classified as having asymptomatic candiduria. Overall, 143 (47%) patients were not managed according to recommended guidelines, including 105/243 (43%) in the asymptomatic candiduria group and 38/62 (61%) in the symptomatic group (P = 0.01). Discordance among asymptomatic patients was driven by overtreatment with an antifungal (98/105 [93%]). Thirty-three percent of patients with asymptomatic candiduria not managed according to the guidelines were treated for over 7 days, and 5% received over 14 days of therapy. Fluconazole was the most commonly used empirical antifungal among asymptomatic candiduria patients (96%), followed by micafungin (4%). Asymptomatic candiduria patients not managed according to the guidelines had a trend toward higher 30-day readmission (35% versus 26%, P = 0.27). Inappropriate management of candiduria among hospitalized patients was high, leading to overtreatment with antifungal therapy.

Project description:BackgroundCandiduria is common in hospitalized patients. Its management is limited because of inadequate understanding. Previous epidemiological studies based on culture assay have been limited to small study populations. Therefore, data collected by automated systems from a large target population are necessary for more comprehensive understanding of candiduria in hospitalized patients.MethodsTo determine the performance of the Sysmex UF-1000i in detecting candiduria, a cross-sectional study was designed and conducted. A total of 203 yeast-like cell (YLC)-positive and 127 negative samples were randomly chosen and subjected to microbiologic analysis. The receiver operating characteristic curve (ROC) was used to evaluate the ability of YLC counts as measured by the Sysmex UF1000i to predict candiduria. Urinalysis data from 31,648 hospitalized patients were retrospectively investigated, and statistical analysis was applied to the data collected.ResultsUsing a cutoff value of 84.6 YLCs/µL, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the yeast like cell (YLC) counts to predict candiduria were 61.7%, 84.1%, 88.6% and 66.3%, respectively. C. glabrata (33.6%) and C. tropicalis (31.4%) were more prevalent than C. albicans (24.3%) in the present study. Of the investigated hospitalized patients, 509 (1.61%) were considered candiduria-positive. Age, gender and basic condition were associated with candiduria in hospitalized patients. In the ICU setting, urinary catheterization appeared to be the only independent risk factor contributing to candiduria according to our investigation. Although antibiotic therapy has been reported to be a very important risk factor, we could not confirm its significance in ICU candiduria patients because of excessive antibiotic usage in our hospital.ConclusionsThe YLC measured by Sysmex UF-1000i is a practical and convenient tool for clinical candiduria screening prior to microbiologic culture. Candiduria is common in hospitalized patients, and its incidence varies according to age, gender and the wards where it is isolated. Candiduria had no direct connection with mortality but might be considered a marker of seriously ill patients who need particular attention in the clinic.

Project description:IntroductionAntimicrobial treatment of asymptomatic bacteriuria (ASB) is one of the most common unnecessary uses of antimicrobials. Earlier studies have shown that the prevalence of this inappropriate treatment ranges from 45% to 83%. Multifaceted interventions based on international guidelines and antimicrobial stewardship can decrease overtreatment of ASB. We have designed a study protocol with the main objective of reducing overtreatment of ASB by 50% through use of a deimplementation strategy.Methods and analysisWe will use a stepped-wedge cluster randomised design, comparing outcomes before and after introduction of our intervention in the emergency department (ED) of five hospitals (clusters) in the Netherlands. All patients (≥18 years old) who have a urine test performed in the ED will be screened for eligibility. The deimplementation strategy consists of a combination of interventions, including education, audit and feedback. The primary endpoint is overtreatment of ASB in patients without risk factors (eg, pregnancy, planned invasive urological procedures and neutropenia). Secondary endpoints are the duration of antimicrobial treatment for ASB, the number of urine cultures and urinalysis per 1000 patients, and overtreatment of positive urinalysis in asymptomatic patients.Ethics and disseminationEthical approval was obtained from the medical ethics research committee of the Academic Medical Centre (Amsterdam, the Netherlands) with a waiver for informed consent. Local feasibility was obtained by the local institutional review boards of all participating hospitals. Our study aims to reduce inappropriate screening and treatment of ASB in EDs, improve healthcare quality, lower the increase in antimicrobial resistance and save costs. If proven (cost)-effective, this study provides a well-suited strategy for a nationwide approach to reduce overtreatment of ASB. Relevant results of our study will be disseminated through publications in peer-reviewed journals and presentations at relevant (scientific) conferences.Trial registration numberNL8242; Pre-results.

Project description:BackgroundSedative-hypnotics are frequently prescribed for insomnia in hospital but are associated with preventable harms.Objective, design, and participantsWe aimed to examine whether a sedative-hypnotic reduction quality improvement bundle decreases the rate of sedative-hypnotic use among hospitalized patients, who were previously naïve to sedative-hypnotics. This interrupted time series study occurred between May 2016 and January 2019. Control data for 1 year prior to implementation and intervention data for at least 16 months were collected. The study occurred on 7 inpatient wards (general medicine, cardiology, nephrology, general surgery, and cardiovascular surgery wards) across 5 teaching hospitals in Toronto, Canada.InterventionParticipating wards implemented a sedative-hypnotic reduction bundle (i.e., order set changes, audit-feedback, pharmacist-enabled medication reviews, sleep hygiene, daily sleep huddles, and staff/patient/family education) aimed to reduce in-hospital sedative-hypnotic initiation for insomnia in patients who were previously naïve to sedative-hypnotics. Each inpatient ward adapted the bundle prior to sustaining the intervention for a minimum of 16 months.Main measuresThe primary outcome measure was the proportion of sedative-hypnotic-naïve inpatients newly prescribed a sedative-hypnotic for sleep in hospital. Secondary measures include prescribing rates of other sedating medications, fall rates, length of stay, and mortality.Key resultsWe included 8,970 patient discharges in the control period and 10,120 in the intervention period. Adjusted sedative-hypnotic prescriptions among naïve patients decreased from 15.48% (95% CI: 6.09-19.42) to 9.08% (p<0.001) (adjusted OR 0.814; 95% CI: 0.667-0.993, p=0.042). Unchanged secondary outcomes included mortality (adjusted OR 1.089; 95% CI: 0.786-1.508, p=0.608), falls (adjusted rate ratio 0.819; 95% CI: 0.625-1.073, p=0.148), or other sedating drug prescriptions (adjusted OR 1.046; 95% CI: 0.873-1.252, p=0.627).ConclusionsA sedative-hypnotic reduction quality improvement bundle implemented across 5 hospitals was associated with a sustained reduction in sedative-hypnotic prescriptions.

Project description:Recent evidence links rosacea to systemic disease, but there are not enough methodologic studies addressing this association in Asians. Our aim was to identify rosacea comorbidities in Koreans and establish a reference database. A multi-center, case-control study was performed where a total of 12,936 rosacea patients and 12,936 age- and sex-matched control subjects were identified from 2007 to 2018. Logistic regression was performed to find significant association between rosacea and Sjögren syndrome (odds ratio [OR] 2.05; 95% confidence interval, 1.40-3.00), systemic sclerosis (OR 6.56; 95% CI, 1.50-28.7), rheumatoid arthritis (OR 1.72; 95% CI, 1.50-1.98), ankylosing spondylitis (OR 2.32; 95% CI, 1.42-3.84), autoimmune thyroiditis (OR 1.96; 95% CI, 1.40-2.73), alopecia areata (OR 1.77; 95% CI, 1.27-2.45), vitiligo (OR 1.90; 95% CI, 1.30-2.77), lung cancer (OR 1.54; 95% CI, 1.06-2.21), hepatobiliary cancer (OR 1.38; 95% CI, 1.06-1.77), alcohol abuse (OR 1.59; 95% CI, 1.05-2.39), diabetes mellitus (OR 1.11; 95% 1.02-1.19), obesity (OR 1.72; 95% CI, 1.22-2.41), allergic rhinitis (OR 1.65; 95% CI, 1.54-1.76), allergic conjunctivitis (OR 1.57; 95% CI, 1.27-1.94), chronic rhinosinusitis (OR 1.28; 95% CI, 1.14-1.42), herpes infection (OR 1.69; 95% CI, 1.53-1.86), and human papillomavirus infection (OR 2.50; 95% CI, 2.06-3.02). Higher odds for Sjogren syndrome, systemic sclerosis, ankylosing spondylitis, thyroiditis, vitiligo, hepatobiliary cancer, and obesity was exclusive in female subjects with rosacea, whereas increased prevalence of alopecia areata and alcohol abuse was confined to men. Only those who were 50 years and older exhibited higher odds for vitiligo, lung cancer, and gastroesophageal reflux disease while individuals younger than 50 were exclusively associated with hepatobiliary cancer, allergic conjunctivitis, and irritable bowel syndrome. Our study suggests that Koreans with rosacea are more likely to experience systemic comorbidity. Clinicians should acknowledge these interrelations and employ comprehensive care with an individual-based approach.
