Hospital Acquired

Hospital-acquired infections (HAIs) are common in intensive care unit (ICU) patients and are associated with increased morbidity and mortality. There has been an increasing effort to prevent HAIs, and infection control practices are paramount in avoiding these complications. In the last several years, numerous developments have been seen in the infection prevention strategies in various health care settings. This article reviews the modern trends in infection control practices to prevent HAIs in ICUs with a focus on methods for monitoring hand hygiene, updates in isolation precautions, new methods for environmental cleaning, antimicrobial bathing, prevention of ventilator-associated pneumonia, central line-associated bloodstream infections, catheter-associated urinary tract infections, and Clostridium difficile infection.

The validity of the central line-associated bloodstream infection (CLABSI) measure is compromised by subjectivity. We observed significant decreases in both CLABSIs and total hospital-acquired bloodstream infections (BSIs) following a CLABSI prevention intervention in adult intensive care units. Total hospital-acquired BSIs could be explored as an adjunct, objective CLABSI measure.

The Impact

Background: Discontinuation of contact precautions for methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE) have failed to show an increase in associated transmission or infections in adult healthcare settings. Pediatric experience is limited. Objective: We evaluated the impact of discontinuing contact precautions for MRSA, VRE, and extended-spectrum β-lactamase–producing gram-negative bacilli (ESBLs) on device-associated healthcare-associated infections (HAIs). Methods: In October 2018, contact precautions were discontinued for children with MRSA, VRE, and ESBLs in a large, tertiary-care pediatric healthcare system comprising 2 hospitals and 620 beds. Coincident interventions that potentially reduced HAIs included blood culture diagnostic stewardship (June 2018), a hand hygiene education initiative (July 2018), a handshake antibiotic stewardship program (December 2018) and multidisciplinary infection prevention rounding in the intensive care units (November 2018). Compliance with hand hygiene and HAI prevention bundles were monitored. Device-associated HAIs were identified using standard definitions. Annotated run charts were used to track the impact of interventions on changes in device-associated HAIs over time. Results: Average hand hygiene compliance was 91%. Compliance with HAI prevention bundles was 81% for ventilator-associated pneumonias, 90% for catheter-associated urinary tract infections, and 97% for central-line–associated bloodstream infections. Overall, device-associated HAIs decreased from 6.04 per 10,000 patient days to 3.25 per 10,000 patient days after October 2018 (Fig. 1). Prior to October 2018, MRSA, VRE and ESBLs accounted for 10% of device-associated HAIs. This rate decreased to 5% after October 2018. The decrease in HAIs was likely related to interventions such as infection prevention rounds and handshake stewardship. Conclusions: Discontinuation of contact precautions for children with MRSA, VRE, and ESBLs were not associated with increased device-associated HAIs, and such discontinuation is likely safe in the setting of robust infection prevention and antibiotic stewardship programs.Funding: NoneDisclosures: None

Background: Central line–associated bloodstream infections are serious life-threatening infections in the intensive care unit setting. Methods: To analyze the impact of the International Nosocomial Infection Control Consortium (INICC) Multidimensional Approach (IMA) and INICC Surveillance Online System (ISOS) on central line–associated bloodstream infection rates in Bahrain from January 2013 to December 2016, we conducted a prospective, before-after surveillance, cohort, observational study in one intensive care unit in Bahrain. During baseline, we performed outcome and process surveillance of central line–associated bloodstream infection on 2320 intensive care unit patients, applying Centers for Disease Control and Prevention’s National Healthcare Safety Network definitions. During intervention, we implemented IMA through ISOS, including (1) a bundle of infection prevention interventions, (2) education, (3) outcome surveillance, (4) process surveillance, (5) feedback on central line–associated bloodstream infection rates and consequences, and (6) performance feedback of process surveillance. Bivariate and multivariate regression analyses were performed using a logistic regression model to estimate the effect of the intervention on the central line–associated bloodstream infection rate. Results: During baseline, 672 central line days and 7 central line–associated bloodstream infections were recorded, accounting for 10.4 central line–associated bloodstream infections per 1000 central line days. During intervention, 13,020 central line days and 48 central line–associated bloodstream infections were recorded. After the second year, there was a sustained 89% cumulative central line–associated bloodstream infection rate reduction to 1.2 central line–associated bloodstream infections per 1000 central line days (incidence density rate, 0.11; 95% confidence interval 0.1–0.3; p, 0.001). The average extra length of stay of patients with central line–associated bloodstream infection was 23.3 days, and due to the reduction of central line–associated bloodstream infections, 367 days of hospitalization were saved, amounting to a reduction in hospitalization costs of US$1,100,553. Conclusion: Implementing IMA was associated with a significant reduction in the central line–associated bloodstream infection rate in Bahrain.

Background: Stenotrophomonas maltophilia is a Gram-negative bacillus and opportunistic emergent pathogen causing hospi- tal-acquired infections (HAIs). Due to risk factors such as prolonged intensive care unit stay and invasive procedures, it has become one of the leading causes of HAIs. Objective: The aim of this study was to evaluate the epidemiology of S.maltophilia infections over a six-year period at Düzce University Hospital, Turkey. Methods: The incidence, clinical characteristics, antimicrobial susceptibility and outcomes of nosocomial S. maltophilia in- fections during this period were retrospectively analyzed. Results: During the study period, 67 samples obtained from 61 patients were identified. Pneumonias (82%) were the most common HAIs, followed by bloodstream infections (10.5%), urinary tract infections (3%), skin and soft tissue infections (3%) and surgical site infection (1.5%). Admission to intensive care, hospitalization exceeding 30 days, and previous use of broad-spectrum antibiotics constituted risk factors. Resistance to cotrimoxazole (6%) was lower than that to levofloxacin (18%). Conclusion: The most important risk factors for S.maltophilia infection in patients are previous exposure to antibiotics, pro- longed hospitalization and invasive procedures such as mechanic ventilation. Discharging patients as early as possible with the rational use of antibiotics may be effective in reducing S. maltophilia infections and resistance rates.

Device-associated infections cause substantial morbidity in children. These healthcare-associated infections (HAI) can increase length of stay and healthcare costs. The strategies used to prevent device-associated infections in children can vary, depending on many patient-specific factors, including the child’s age and physical location when receiving inpatient pediatric care. In addition, infection prevention strategies in children are not always the same as adult prevention strategies. This chapter reviews practical, evidence-based strategies to prevent pediatric ventilator-associated events (VAE), central line–associated bloodstream infections (CLABSI), and catheter-associated urinary tract infections (CAUTI). The recommendations focus on patients outside the neonatal intensive care unit (NICU) setting.

The Impact

Hospital-acquired infections (HAIs) are a global public health concern. As the COVID-19 pandemic continues, its contribution to mortality and antimicrobial resistance (AMR) grows, particularly in intensive care units (ICUs). A two-year retrospective study from April 2019–April 2021 was conducted in an adult ICU at the Hospital for Infectious and Tropical Diseases, Belgrade, Serbia to assess causative agents of HAIs and AMR rates, with the COVID-19 pandemic ensuing halfway through the study. Resistance rates >80% were observed for the majority of tested antimicrobials. In COVID-19 patients, Acinetobacter spp. was the dominant cause of HAIs and more frequently isolated than in non-COVID-19 patients. (67 vs. 18, p = 0.001). Also, resistance was higher for imipenem (56.8% vs. 24.5%, p < 0.001), meropenem (61.1% vs. 24.3%, p < 0.001) and ciprofloxacin (59.5% vs. 36.9%, p = 0.04). AMR rates were aggregated with findings from our previous study to identify resistance trends and establish empiric treatment recommendations. The increased presence of Acinetobacter spp. and a positive trend in Klebsiella spp. resistance to fluoroquinolones (R2 = 0.980, p = 0.01) and carbapenems (R2 = 0.963, p = 0.02) could have contributed to alarming resistance rates across bloodstream infections (BSIs), pneumonia (PN), and urinary tract infections (UTIs). Exceptions were vancomycin (16.0%) and linezolid (2.6%) in BSIs; tigecycline (14.3%) and colistin (0%) in PNs; and colistin (12.0%) and linezolid (0%) in UTIs. COVID-19 has changed the landscape of HAIs in our ICUs. Approval of new drugs and rigorous surveillance is urgently needed.

AbstractCentral line-associated bloodstream infections (CLABSIs) are the most frequent pediatric hospital-acquired infections and significantly impact outcomes. The aim of this study was to estimate the attributable mortality for CLABSIs in pediatric and neonatal patients in Greece. A retrospective matched-cohort study was performed, in two tertiary pediatric hospitals. Inpatients with a central line in neonatal and pediatric intensive care units (NICUs and PICUs), hematology/oncology units, and a bone marrow transplantation unit between June 2012 and June 2015 were eligible. Patients with confirmed CLABSI were enrolled on the day of the event and were matched (1:1) to non-CLABSI patients by hospital, hospitalization unit, and length of stay prior to study enrollment (188 children enrolled, 94 CLABSIs). Attributable mortality was estimated. During the study period, 22 CLABSIs and nine non-CLABSIs died (23.4 vs. 9.6%, respectively, p = 0.011), leading to an attributable mortality of 13.8% (95% confidence interval [CI] = 3.4–24.3%). Children in PICUs were more likely to die, presenting an attributable mortality of 20.2% (95% CI = − 1.4–41.8%), without reaching, however, statistical significance. After multiple logistic regression, CLABSIs were four times more likely to die (odds ratio [OR] = 4.29, 95% CI = 1.28–14.36, p = 0.018). Survival analysis showed no difference in time to death after study enrollment between CLABSIs and non-CLABSIs (log-rank p = 0.137, overall median survival time = 7.8 months). Greek pediatric mortality rates are increased by the CLABSI occurrence, highlighting the importance of infection prevention strategies.
