ABSTRACT

OBJECTIVE: To reduce both inappropriate testing for and diagnosis of healthcare-onset (HO) Clostridioides difficile infections (CDIs). DESIGN: We performed a retrospective analysis of C. difficile testing from hospitalized children before (October 2017-October 2018) and after (November 2018-October 2020) implementing restrictive computerized provider order entry (CPOE). SETTING: Study sites included hospital A (a ∼250-bed freestanding children's hospital) and hospital B (a ∼100-bed children's hospital within a larger hospital) that are part of the same multicampus institution. METHODS: In October 2018, we implemented CPOE. No testing was allowed for infants aged ≤12 months, approval of the infectious disease team was required to test children aged 13-23 months, and pathology residents' approval was required to test all patients aged ≥24 months with recent laxative, stool softener, or enema use. Interrupted time series analysis and Mann-Whitney U test were used for analysis. RESULTS: An interrupted time series analysis revealed that from October 2017 to October 2020, the numbers of tests ordered and samples sent significantly decreased in all age groups (P < .05). The monthly median number of HO-CDI cases significantly decreased after implementation of the restrictive CPOE in children aged 13-23 months (P < .001) and all ages combined (P = .003). CONCLUSION: Restrictive CPOE for CDI in pediatrics was successfully implemented and sustained. Diagnostic stewardship for CDI is likely cost-saving and could decrease misdiagnosis, unnecessary antibiotic therapy, and overestimation of HO-CDI rates.

ABSTRACT

We sought to describe the characteristics of catheter-associated urinary tract infections (CAUTIs) in a children's hospital while demonstrating efficacy of electronic identification of CAUTIs. There were 25 CAUTIs identified over 24 months, with most (88%) occurring in the intensive care units (ICUs). The incidence of ICU CAUTIs decreased during the study period (P = .04). Concordance between electronic identification and validation by infection control staff was 83% and increased to 100% with correction of nursing documentation.

ABSTRACT

Few recent studies have assessed the epidemiology of health care-associated infections (HAIs) in the pediatric population after cardiac surgery. A retrospective cohort study was performed to assess the epidemiology of several types of HAIs in children 18 years of age or younger undergoing cardiac surgery from July 2010 to June 2012. Potential pre-, intra-, and postoperative risk factors, including adherence to the perioperative antibiotic prophylaxis regimen at the authors' hospital, were assessed by multivariable analysis using Poisson regression models. Microorganisms associated with HAIs and their susceptibility patterns were described. Overall, 634 surgeries were performed, 38 (6 %) of which were complicated by an HAI occurring within 90 days after surgery. The HAIs included 7 central line-associated bloodstream infections (CLABSIs), 12 non-CLABSI bacteremias, 6 episodes of early postoperative infective endocarditis (IE), 9 surgical-site infections (SSIs), and 4 ventilator-associated pneumonias (VAPs). Mechanical ventilation (rate ratio [RR] 1.07 per day; 95 % confidence interval [CI] 1.03-1.11; p = 0.0002), postoperative transfusion of blood products (RR 3.12; 95 %, CI 1.38-7.06; p = 0.0062), postoperative steroid use (RR 3.32; 95 % CI 1.56-7.02; p = 0.0018), and continuation of antibiotic prophylaxis longer than 48 h after surgery (RR 2.56; 95 % CI 1.31-5.03; p = 0.0062) were associated with HAIs. Overall, 66.7 % of the pathogens associated with SSIs were susceptible to cefazolin, the perioperative antibiotic prophylaxis used by the authors' hospital. In conclusion, HAIs occurred after 6 % of cardiac surgeries. Bacteremia and CLABSI were the most common. This study identified several potentially modifiable risk factors that suggest interventions. Further studies should assess the role of improving adherence to perioperative antibiotic prophylaxis, the age of transfused red blood cells, and evidence-based guidelines for postoperative steroids.
