Longitudinal changes in hand hygiene adherence among healthcare workers during the COVID-19 pandemic, Dominican Republic

Hand hygiene (HH) can reduce transmission of healthcare-associated infections (HAIs) in healthcare facilities and is especially important in low- and middle-income countries where HH infrastructure may be insufficient and the burden of HAIs is highest. At baseline, we assessed HH infrastructure and practices among healthcare workers (HCWs) at two large hospitals in the Dominican Republic during the COVID-19 pandemic. HCWs were observed for HH adherence (HHA) (defined as the use of alcohol-based hand rub (ABHR) or handwashing with soap and water) before and after patient contact and donning new gloves before patient contact. The baseline assessment was repeated following implementation of local production and distribution of ABHR and a HH promotion campaign. Descriptive analyses and regression models evaluated predictors of HHA and glove use. Cumulative HHA was 18.9%. While patient-care areas with a functional HH resource increased from 47% at baseline to 92% after the intervention, HHA declined from 23.0% to 16.7%. HHA was higher after patient contact (aOR = 5.88; 95% CI = 4.17–8.33), during a period of increased COVID-19 risk (aOR = 1.69; 95% CI = 1.05–2.77), during invasive patient contacts (aOR = 1.64; 95% CI = 1.23–2.17) and when gloves were not used (aOR = 1.25; 95% CI = 1.01–1.56). The negative association between glove use and HHA diminished when access to HH resources increased. New gloves were donned before 39.6% of patient contacts. Glove use was higher among nurses (aOR = 7.12; 95% CI = 3.02–16.79) and during invasive contacts (aOR = 4.76; 95% CI = 2.27–10.0). While access to HH resources increased after the interventions, HHA did not increase. HHA was lower when COVID-19 risk was lower. Findings from this study may guide future efforts to increase HHA among HCWs.

Infection prevention and control compliance during COVID-19 pandemic era: assessment of 26 regional referral hospitals in Tanzania

BackgroundInfection prevention and control (IPC) implementation at referral hospitals (RHs) in Tanzania is still inadequate, regardless of ongoing IPC capacity-building initiatives. This continues to challenge the quality of healthcare service provision as poor IPC implementation fuels healthcare-associated infections (HAIs) and antimicrobial resistance (AMR) problems. The study aimed to describe the implementation of IPC practices in 26 Regional RHs’ functional units in 2021.MethodsThe study involved secondary data from an assessment conducted using the National IPC Standard checklist for hospitals to all functional units at 26 regional RHs in 2021. Data were analysed in STATA version 15.0 to compute the weighted median with interquartile range (IQR) for each functional unit score.ResultsThe overall weighted median IPC compliance with 26 regional RHs in 2021 was 50 (41–60), whereby the lowest and highest scores were 24 and 72%, respectively. The highest-performing unit was the intensive care unit (ICU) for adults 71.4% (46.4–78.6), and lowest performing functional units were the mortuary, Central Sterilization and Supply Department, and blood transfusion [47.4% (36.8–57.9), 47.4% (40–50), and 47.6% (38.1–61.9)], respectively.ConclusionImplementation of IPC practices in 26 RHs in Tanzania is inadequate. We recommend that RHs need to strengthen IPC practices implementation in each functional unit in order to reach the required target of at least 80% score. This will enhance the reduction of the burden of HAIs and AMR, and increase the energy and morale of healthcare workers in preparedness and response to emerging and remerging diseases.

Burden of nosocomial infections in intensive care units: Cost of antibiotics, the extra length of stay and mortality rate.

Healthcare-associated infections (HAIs) in intensive care unit (ICU) patients significantly complicate the normal hospitalization process and affect patients' condition, length of hospitalization, mortality, and treatment cost. In this study, we aimed to determine the prevalence and economic burden of HAIs. The study involved all patients with a confirmed HAIs (based on CDC/NHSN case-definitions); in the general ICU of a tertiary university hospital in Tehran, from April 2020 to March 2021. The patients' information, including length of hospitalization, outcome, type and cost of prescribed antibiotics, were recorded. During the study period, 119 HAIs were found in 1395 (43% F / 57% M) patients. The prevalence of nosocomial infections was 8.53%. The mean duration of hospitalization in all ICU patients was 4.7 ± 3.1 days, and 31.85 ± 18.96 days in patients with HAIs. The most common organisms involved in HAIs are Acinetobacter baumannii (54.6%), Klebsiella pneumoniae (30.3%), E. coli (15.1%), and Enterococcus spp. (12%). Incidence density of ventilator-associated pneumonia (VAP), central line-associated bloodstream infection (CLA-BSI), and catheter-associated urinary tract infection (CA-UTI) per 1000 device-days were 36.08, 17.57, and 8.86, respectively. The total cost of antibiotics for HAIs was € 105,407. Among these, the highest consumption costs were for carbapenems, followed by colistin and caspofungin. This study showed the high burden of nosocomial infections in ICUs. Strategies for more strict infection prevention and control are necessary to reduce this burden.

2488. Healthcare-associated infections in acute care hospitals in Greece, results of the third Point Prevalence Survey, April – December 2022

Abstract Background The burden of healthcare-associated infections (HAIs) in European acute care hospitals is estimated through periodic Point Prevalence Studies (PPS) coordinated by European Centre for Disease Prevention and Control (ECDC). In 2016, Greece had the highest HAI prevalence among European countries (10%). The current PPS aimed to estimate the prevalence of HAIs among inpatients, especially in the context of COVID-19 pandemic. Methods A cross-sectional study was conducted between April and December 2022, according to ECDC PPS protocol v.6.1, in a representative sample of 50 Greek hospitals across all country regions. Patients admitted in wards before 8.00 am of the study day were screened for inclusion. Infection control teams collected hospital characteristics (e.g., total beds, infection control markers), wards (specialty, bed occupancy) and active HAIs (type, origin, microbiological results). Active HAIs included present HAIs or past HAIs that are still being treated. ECDC HelicsWin.Net software v.4.4.0, was used for data entry and analysis. Results Overall, 12.1% inpatients (1,175 of a total 9,707) had at least one active HAI. Among the 1,408 HAIs, the most commonly observed were lower respiratory tract infections (28.9%), bloodstream infections (20%), among which 4.6% were catheter-related, and urinary tract infections (13.1%), as shown in table 1. HAI prevalence was higher in patients of intensive care units (45.7%), compared to medical (13.5%) and surgical ones (8.2%). Laboratory data were available for 58.9% of HAIs and 1,259 microorganisms were identified. Klebsiella species (20.5%), Acinetobacter species (12.8%), P. aeruginosa (10.2%), Candida species (7.9%) and S. aureus (6.3%) were frequent isolates. Antimicrobial susceptibility patterns varied depending on the pathogen (table 2). Conclusion This study shows the increased burden of HAIs among inpatients and the emergence of difficult-to-treat pathogens in Greek hospitals. Subsequent prevalence studies will provide additional evidence regarding the trend in HAI prevalence among inpatients and support the identification of modifiable practices. The invigoration of infection control and antimicrobial stewardship programs in these settings is essential. Disclosures All Authors: No reported disclosures

Impact of COVID-19 Pandemic on Healthcare-Associated Infections: A Systematic Review and Meta-Analysis.

This study investigated how the Coronavirus Disease 2019 (COVID-19) pandemic has affected the rate of healthcare-associated infections (HAIs). PubMed, Scopus and Google Scholar were searched to identify potentially eligible studies published from December 2019 to September 2022. A random effect model was used to determine the changes in the rate of HAIs during the pandemic. Thirty-seven studies, mostly from the United States (n = 13), were included. Fifteen studies described how the pandemic affected the rate of CLABSIs and CAUTIs, and eight of them showed a significant increase in CLABSIs. The risk of CLABSIs and CDIs was 27% (pooled odds ratio [OR]: 0.73; confidence interval [CI]: 0.61-0.89; p < 0.001) and 20% (pooled OR: 1.20; CI: 1.10-1.31; p < 0.001) higher during the pandemic compared to before the COVID-19 pandemic period, respectively. However, the overall risk of HAIs was unaffected by the pandemic (pooled OR: 1.00; 95 CI: 0.80-1.24; p = 0.990). Furthermore, there were no significant changes in the risk of CAUTIs (pooled OR: 1.01; 95 CI: 0.88-1.16; p = 0.890), and SSIs (pooled OR: 1.27; CI: 0.91-1.76; p = 0.16) between the two periods. The COVID-19 pandemic had no effect on the overall risk of HAIs among hospitalized patients, but an increased risk of CLABSIs and CDI were observed during the pandemic. Therefore, more stringent infection control and prevention measures and prudent interventions to promote the rational use of antibiotics are warranted across all healthcare facilities to reduce the burden of HAIs.

Surveillance of Multidrug-Resistant Pathogens in Neonatal Intensive Care Units of Palermo, Italy, during SARS-CoV-2 Pandemic.

Antimicrobial resistance (AMR) is a topic of concern, especially in high-level care departments like neonatal intensive care units (NICUs). The systematic use of an "active" epidemiological surveillance system allows us to observe and analyze any changes in microbial distribution, limiting the risk of healthcare-associated infection (HAI) development. We have conducted a longitudinal observational study in the five NICUs of Palermo, comparing the "pre-pandemic period" (March 2014-February 2020) with the "pandemic" one (March 2020-February 2022). The primary aim of the study was to evaluate the cumulative prevalence of carriage from multi-drug resistant (MDR) bacteria in the cumulative NICUs (NICU C). During the "pre-pandemic period", 9407 swabs were collected (4707 rectal, 4700 nasal); on the contrary, during the "pandemic period", a total of 2687 swabs were collected (1345 rectal, 1342 nasal). A statistically significant decrease in MDR-Gram-negative bacteria (GNB) carriage prevalence was detected during the pandemic. At the same time, there was a general worsening of the carriage of carbapenemase-forming MDR-GNB (CARBA-R+) and methicillin-resistant Staphylococcus aureus (MRSA) during the pandemic period. A significant reduction in methicillin-susceptible Staphylococcus aureus (MSSA) carriage was detected too. The surveillance of MDRO carriage in NICUs is fundamental for limiting the social and economic burden of HAIs.

An Observational Study from Northern India to Evaluate Catheter-associated Urinary Tract Infection in Medical Intensive Care Unit at a Tertiary Care Center.

Healthcare-associated infections are the leading cause of morbidity and mortality in hospitalized patients. Catheter-associated urinary tract infection (CAUTI) is a leading infection in ICU settings. This study aims to evaluate the patient and catheter-related factors contributing to the urinary tract infection as well as implementing the preventive measures ultimately curbing down the burden of healthcare-associated infections. This is a hospital-based observational study conducted in Department of Microbiology, from October 2020 to September 2021. A total of 150 patients admitted to Medical Intensive Care Unit (MICU) with the indwelling urinary catheter were included. Urine samples were collected with proper aseptic precautions and processed within 2 hours of collection. Identification and antimicrobial susceptibility testing of the isolated pathogens was done as per CLSI guidelines 2019. In this study, the CAUTI rate was 9.4 per 1000 urinary catheter days, while the overall magnitude was 14.67%. It was predominantly reported in 51-70-years age group (34%), and females (63.63%) outnumbered males (36.36%), with Escherichia coli being the commonest pathogen. The highest incidence was reported in the 3rd week of catheterization with diabetes being a predominant risk factor (17.24%). This study provides baseline data on CAUTI rate, pathogens isolated, and risk factors at our institute. The overall goal is to identify, educate, and implement best-practice measures for prevention and curbing down the incidence rates of catheter-associated urinary tract infections.

Intermittent point prevalence surveys on healthcare-associated infections, 2011 and 2016, in England: what are the surveillance and intervention priorities?

Point prevalence surveys are an important surveillance method for determining the burden of healthcare-associated infections (HCAIs). To outline the key results of two point prevalence surveys in England (2011 and 2016). All National Health Service and independent sector hospitals in England were eligible to participate. Data were collected between September and November in both 2011 and 2016 based on the protocol and codebook devised by the European Centre for Disease Prevention and Control. Analysis was performed using Stata Version 13 and SAS Version 9.3. A mixed-effects model was applied, which allowed estimation of organization-specific means and accounted for the heterogeneity in the responses from different organizations. A total of 100,755 case records were included (52,433 in 2011 and 48,312 in 2016). The estimated prevalence of HCAIs was slightly higher in 2016 [6.89%, 95% confidence interval (CI) 6.21-7.57%] than in 2011 (6.41%, 95% CI 5.75-7.06%). In both surveys, the prevalence of HCAIs was highest in adult intensive care units (23.1% in 2011, 21.2% in 2016), and pneumonia/lower respiratory tract infections was the most common cause of HCAIs (22.7% in 2011 vs 29.2% in 2016). Inpatients in acute hospitals were older and had higher risk of dying in 2016 compared with 2011; however, the proportion of inpatients with HCAIs or on antibiotics did not differ significantly. The burden of HCAIs in English hospitals increased slightly between 2011 and 2016. However, the proportion of inpatients with HCAIs or on antibiotics did not differ significantly.

Healthcare-associated infections and antimicrobial resistance in Canadian acute care hospitals, 2017-2021.

Healthcare-associated infections (HAIs) and antimicrobial resistance (AMR) continue to contribute to excess morbidity and mortality among Canadians. This report describes epidemiologic and laboratory characteristics and trends of HAIs and AMR from 2017 to 2021 (Candida auris 2012-2021) using surveillance and laboratory data submitted by hospitals to the Canadian Nosocomial Infection Surveillance Program (CNISP) and by provincial laboratories to the National Microbiology Laboratory (NML). Data collected from 88 Canadian sentinel acute care hospitals between January 1, 2017, and December 31, 2021, for Clostridioides difficile infections (CDI), carbapenemase-producing Enterobacterales (CPE), methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections (BSIs) and vancomycin-resistant Enterococcus (VRE) BSIs. Candida auris (C. auris) surveillance was initiated in 2019 by CNISP and in 2012 by the NML. Case counts, rates, outcomes, molecular characterization and antimicrobial resistance profiles are presented. From 2017 to 2021, increased rates per 10,000 patient days were observed for MRSA BSIs (35%; 0.84-1.13), VRE BSIs (43%; 0.23-0.33) and CPE infections (166%, 0.03-0.08). CDI rates decreased 11% (5.68-5.05). Thirty-one C. auris isolates were identified in Canada from 2012 to 2021, with the majority from Western Canada (68%). From 2017 to 2021, the incidence of MRSA and VRE BSIs, and CPE infections increased in Canadian acute care hospitals participating in a national sentinel network (CNISP) while CDI decreased. Few C. auris isolates were identified from 2012 to 2021. Reporting standardized surveillance data and the consistent application of infection prevention and control practises in acute care hospitals are critical to help decrease the burden of HAIs and AMR in Canada.

Mechanistic insights of Euphorbia milii des moul mediated biocompatible and non-cytotoxic, antimicrobial nanoparticles: an answer to multidrug resistant bacteria.

The emergence of drug-resistant microbial pathogens is a matter of global concern and become more serious if they linked with healthcare-associated infections (HAIs). As per World Health Organization statistics, multidrug-resistant (MDR) bacterial pathogens account for between 7 and 12%of the worldwide burden of HAIs. The need for an effective and environmentally sustainable response to this situation is urgent. The primary goal of this study was to create copper nanoparticles that are biocompatible and non-toxic by using an extract of Euphorbia des moul, and then to test these nanoparticles' bactericidal efficacy against MDR strains of Escherichia coli, Klebsiella spp., Pseudomonas aeruginosa, and Acinetobacter baumannii. UV-Vis spectroscopy, dynamic light scattering, X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, and scanning electron microscopy techniqueswere used to characterize the biogenic G-CuNPs. It was found thatG-CuNPs were spherical inshape,with an average diameter of ~ 40nm and a charge density of - 21.52mV. The G-CuNPsfully eradicated the MDR strains at a dosage of 2mg/ml with 3h of incubation time. Mechanistic analysisshowed that theG-CuNPs efficiently disrupted the cell membrane and damaged the DNA and by generating more reactive oxygen species. Moreover, cytotoxic examination revealedthat G-CuNPs displayed < 5% toxicity at 2mg/ml concentration on human RBCs, PBMCs, and A549 cell lines, suggesting that they are biocompatible. This nano-bioagent is an eco-friendly, non-cytotoxic, non-hemolytic organometallic copper nanoparticles (G-CuNPs) with a high therapeutic index for possible use in the prevention of biomedical device-borne infections by preparing an antibacterial layer on indwellingmedical devices. However, its potential clinical use has to be further studied through in vivo testing with an animal model.

Burden of healthcare-associated infections in europe: a systematic literature review

Clinical and economic burden of healthcare-associatedinfections: A prospective cohort study.

Healthcare-associated infections (HAIs) have become a serious public health problem. Despite the fact that implementing evidence-based infection control strategies could prevent HAIs and save billions of dollars, Ethiopia lacks national surveillance studies on the rate, economic, and clinical burden of HAIs. To assess the clinical and economic burden of HAIs in hospitalized patients at Ayder comprehensive specialized hospital. A prospective cohort study design was conducted in patients with and without HAIs. A review of medical records, interviews, and patient bills was used to extract necessary information. The patients in the two arms were matched based on age, sex, Charlson comorbidity index, and ward type. Measurable factors were compared between infected and uninfected patients using the paired ttest or McNemar's test, as appropriate. Logistic regression was used to identify predictors of in-hospital mortality. Stata 14.1 was used to conduct all analyses. A total of 408 patients, 204 with HAIs and 204 without HAIs were included in the study. In-hospital mortality was higher in patients with HAI (14.7% vs 7.8%, P = 0.028). Patients with HAI stayed an average of 8.3 days longer than controls (18.85 vs 10.59, P<0.001). The average direct medical costs for patients with HAI were 3033 Ethiopian birrs (ETB) higher than controls (4826 vs 1793, P<0.001). The presence of HAIs (AOR: 2.22, 95% CI: 1.13-4.39) and admission to intensive care units (AOR: 3.39, 95% CI: 1.55-7.40) were significant predictors of in-hospital mortality. HAIs have a significant impact on in-hospital mortality, the length of extra hospital stays, and extra costs for medical care. Patients admitted to intensive care units and those with HAIs were found to be significant predictors of in-hospital mortality. Interventions must be implemented to prevent HAIs, especially in patients admitted to intensive care units.

Multicentre surveillance of epidemiologically important pathogens causing nosocomial bloodstream infections and pneumonia trials in Brazilian adult intensive care units.

Introduction. Healthcare-associated infections (HAIs) are the most recurrent adverse event in hospitals worldwide and represent an important public health problem.Gap statement. There are a paucity of multicentric data describing severe HAIs such as bloodstream infection (BSI) and pneumonia in Brazil.Aim. To provide an up-to-date picture of the extent and patterns of HAIs in adult intensive care units (ICUs), as well as to identify variables associated with the risk of development of severe infections.Methodology. Point prevalence surveys were conducted using standardized protocols in 35 ICUs from Minas Gerais state, Brazil. Medical records of eligible inpatients at or before 8 am on the survey day were reviewed to identify HAIs present at the time of the survey. A matched-pairs case-control study was performed on a total of 66 pairs for BSI and 115 pairs for pneumonia according to the selection criteria developed.Results. Overall, 171 patients (45.7%) had at least one HAI, with most (78.4%) acquired in the ICU. These patients presented a total of 240 infections; including 123 pneumonia (51.3%) and 66 BSI (27.5%), and 78.9 and 80.3 %, respectively, were acquired in the ICU. Their aetiology showed a predominance of Gram-negative bacteria versus Gram-positive bacteria (48.9 versus 43.3 %), with Acinetobacter baumannii (13.7%) and Pseudomonas aeruginosa (12.8%) being prominent. One striking observation from our data was the higher prevalence of Staphylococcus aureus (14.5%) and coagulase-negative staphylococci (10.2%) observed in the overall HAIs.Conclusion. A high severe ICU-acquired HAI burden was found when compared with findings from other low- and middle-income countries. These data can be utilized for better planning of nosocomial infection surveillance programmes in our hospitals.

SG-APSIC1069: Implementing infection prevention bundle significantly reduced multidrug-resistant organisms infection and healthcare-associated infections in intensive care unit at a national hospital in Vietnam

Objectives: In Vietnam, the burden of healthcare-associated infections (HAIs), especially by multidrug-resistant organisms (MDROs), can be greater at national hospitals where a high number of severe patients from lower-tier hospitals are received for treatment. To reduce MDRO and HAI incidences at the tropical diseases intensive care unit (ICU) of Cho Ray Hospital, the final line of treatment for 20 southern provinces of Vietnam, a comprehensive infection prevention bundle was developed and implemented in 2019. In this retrospective study, we evaluated the effectiveness of this intervention in preventing MDRO infections and HAIs among patients at risk. Methods: The infection prevention bundle included elements to improve administration controls, environmental controls, and personal protective equipment usage. The bundle was implemented via training and active monitoring. Medical data, such as microbiology results, length of hospital stay, treatment cost of all patients admitted to the targeted ICU, and data on adherence to the bundle elements, were collected via routine monitoring from July to December 2019. These data were reviewed and analyzed. An independent 2-sample t test was used to calculate the significance of the differences in MDRO and HAI rates before and after the intervention. Results: The mean number of MDRO infections decreased significantly after implementation of the infection prevention bundle (7.0 vs 3.3; P = .011). HAI and ventilator-associated pneumonia (VAP) rates also decreased significantly (5.9 vs 3.7; P= .013 and 20.4 vs 13.7; P=0.047, respectively). The mean total treatment cost per patient was reduced by 1.8 million VND (US $76.76). Bundle-element adherence was high throughout the intervention period, ranging from 72.7% (putting MDRO sign on beds) to 100% (hand hygiene, cohort patients, environment cleaning). Conclusions: Implementation of an appropriate infection prevention bundle with a high adherence rate by healthcare workers helped to effectively reduce MDRO infection and HAI rates in the tropical diseases ICU.

Healthcare-Associated Infection in Surgery Department: A Big Challenge for African Surgical Teams.

Healthcare-associated infections (HAIs) are increasing in health facilities in Mali, due to health disparities and growing costs. Twenty to fifty percent of HAIs in the surgery department can be prevented with appropriate measures. This study aimed to determine the burden of HAI and its risk factors. This was a prospective cohort study from January to June 2021 at the CHU Gabriel TOURE, Bamako, Mali. The sample size was determined based on the CDC Atlanta criteria, used to confirm HAI in surgical settings. Demographic, clinical, and biological parameters were determined. For the confirmed case of infection, the incriminated bacteria were isolated and tests were performed for the choice of drugs. Of the total 1001 patients included in this study, 195 patients (19.48%) have HAIs. The types of infections were as follows: 70 cases of surgical site infections, 54 infections on burns victims, 40 urinary tract infections, and 31 cases of bacteraemia. Germs such as Escherichia Coli, Klebsiella pneumoniae, and Acinetobacter were often isolated. We found increasing hospital stays as well as some postoperative mortality related to infections. At the end of this study, corrective efforts were implemented to prevent HAI. Among them are improvements in sterilisation techniques as far as surgical materials were concerned. In addition to a surgical checklist, locally used drapes were replaced with single-use surgical supplies. Advanced training of the surgical team on things such as bladder catheterisation was also conducted in the department. It is important to put in place a committee, to prevent nosocomial infection in our hospital. The selected committee will be responsible for planning and implementing diverse strategies to prevent infections. The prevention of HAIs will reduce health costs and improve the quality of surgical care.

The Epidemiology of Healthcare-Associated Bloodstream Infection in an Adult Intensive Care Unit: A Retrospective Cohort Study in a Single Tertiary Care Hospital in Hanoi, Vietnam.

Background Healthcare-associated infections (HAIs), including bloodstream infections (BSIs) in the intensive care unit (ICU), are growing global public health problems. While high-income countries have reported the burden of HAIs precisely, low- and middle-income countries (LMICs), including Vietnam, often lack surveillance systems for HAIs. In Vietnam, few reports described HAI-associated BSIs. Therefore, in this study, we aim to clarify the characteristics of HAI-associated BSIin an adult ICU. Materials and methods We conducteda retrospective cohort study of HAI-associated BSIin the adult ICU of Bach Mai Hospital (BMH), Vietnam, between December 2013 and August 2015. For every case identified with bacteremia, we collected characteristics and laboratory findings of the case andfollowed the length of hospital stay and seven-day and 30-day survival. Predictors of 30-day mortality were analyzed using univariate and multivariate analyses. Results Among the 90 cases identified, the median age of the study cohort was 57 (range: 18-90) years, and 59 (65.6%) were male. Chronic heart disease was the most frequent comorbidity (n = 26, 28.9%). The pathogens isolated were mostly Candida spp. (n = 26, 26.3%) and Enterococcus spp. (n = 19, 19.2%). Among the 90 patients with confirmed HAI-associated BSI, 34 (37.8%) patients survived, while 31 (34.4%)patients died in 30 days. In multivariate analysis, chronic heart disease tended to increase with 30-day all-cause mortality (odds ratio (OR) = 3.5, 95% confidence interval (CI) = 1.0-11.9, p = 0.051). Conclusions Our retrospective cohort study is the largest investigation to describe HAI-associated BSI in an adult ICU in a tertiary care hospital in Vietnam. Improved laboratory detection and infection surveillance systems are needed to reduce HAI-associated BSI.

Microbiology of Healthcare-Associated Infections: Results of a Fourth National Point Prevalence Survey in Serbia.

Millions of patients acquire healthcare-associated infections (HAIs) every year, putting them at risk for serious complications and prolonged hospitalization. Point prevalence surveys (PPS), guided by the European Centre for Disease Prevention and Control framework, are one of the primary methods by which countries in the European Union conduct surveillance of HAIs. Serbia, though not in the EU, implemented this approach in its national PPS. The microbiological and antimicrobial resistance (AMR) analyses comprised patients in 61 out of 65 hospitals included in the fourth PPS conducted in November 2017. A total of 515/12,380 (4.2%) of the adult patients included in the PPS had at least one HAI, with intensive care units carrying the highest prevalence of 15.9%. Urinary tract and surgical site infections were the most frequently identified types of HAIs (23.9% and 23.0%, respectively). Enterobacterales comprised almost half (47.0%) of all causative agents, most notably Klebsiella spp. (16.7%). AMR was very high for most pathogens—80.5% of nonfermentative Gram-negative bacilli were resistant to carbapenems whereas 62.9% of Enterobacterales were resistant to third generation cephalosporins. The calculated AMR index of 61% is one of the highest in Europe. Further efforts are needed to reduce the burden of HAIs in Serbia that carry very high resistance rates to antibiotics currently used in clinical practice.

Health-care-associated bloodstream and urinary tract infections in a network of hospitals in India: a multicentre, hospital-based, prospective surveillance study

Health-care-associated infections (HAIs) cause significant morbidity and mortality globally, including in low-income and middle-income countries (LMICs). Networks of hospitals implementing standardised HAI surveillance can provide valuable data on HAI burden, and identify and monitor HAI prevention gaps. Hospitals in many LMICs use HAI case definitions developed for higher-resourced settings, which require human resources and laboratory and imaging tests that are often not available. A network of 26 tertiary-level hospitals in India was created to implement HAI surveillance and prevention activities. Existing HAI case definitions were modified to facilitate standardised, resource-appropriate surveillance across hospitals. Hospitals identified health-care-associated bloodstream infections and urinary tract infections (UTIs) and reported clinical and microbiological data to the network for analysis. 26 network hospitals reported 2622 health-care-associated bloodstream infections and 737 health-care-associated UTIs from 89 intensive care units (ICUs) between May 1, 2017, and Oct 31, 2018. Central line-associated bloodstream infection rates were highest in neonatal ICUs (>20 per 1000 central line days). Catheter-associated UTI rates were highest in paediatric medical ICUs (4·5 per 1000 urinary catheter days). Klebsiella spp (24·8%) were the most frequent organism in bloodstream infections and Candida spp (29·4%) in UTIs. Carbapenem resistance was common in Gram-negative infections, occurring in 72% of bloodstream infections and 76% of UTIs caused by Klebsiella spp, 77% of bloodstream infections and 76% of UTIs caused by Acinetobacter spp, and 64% of bloodstream infections and 72% of UTIs caused by Pseudomonas spp. The first standardised HAI surveillance network in India has succeeded in implementing locally adapted and context-appropriate protocols consistently across hospitals and has been able to identify a large number of HAIs. Network data show high HAI and antimicrobial resistance rates in tertiary hospitals, showing the importance of implementing multimodal HAI prevention and antimicrobial resistance containment strategies.

An outbreak of Burkholderia cepacia bloodstream infections in a tertiary-care facility in northern India detected by a healthcare-associated infection surveillance network.

The burden of healthcare-associated infections (HAIs) is higher in low- and middle-income countries, but HAIs are often missed because surveillance is not conducted. Here, we describe the identification of and response to a cluster of Burkholderia cepacia complex (BCC) bloodstream infections (BSIs) associated with high mortality in a surgical ICU (SICU) that joined an HAI surveillance network. A 780-bed, tertiary-level, public teaching hospital in northern India. After detecting a cluster of BCC in the SICU, cases were identified by reviewing laboratory registers and automated identification and susceptibility testing outputs. Sociodemographic details, clinical records, and potential exposure histories were collected, and a self-appraisal of infection prevention and control (IPC) practices using assessment tools from the World Health Organization and the US Centers for Disease Control and Prevention was conducted. Training and feedback were provided to hospital staff. Environmental samples were collected from high-touch surfaces, intravenous medications, saline, and mouthwash. Between October 2017 and October 2018, 183 BCC BSI cases were identified. Case records were available for 121 case patients. Of these 121 cases, 91 (75%) were male, the median age was 35 years, and 57 (47%) died. IPC scores were low in the areas of technical guidelines, human resources, and monitoring and evaluation. Of the 30 environmental samples, 4 grew BCC. A single source of the outbreak was not identified. Implementing standardized HAI surveillance in a low-resource setting detected an ongoing Burkholderia cepacia outbreak. The outbreak investigation and use of a multimodal approach reduced incident cases and informed changes in IPC practices.
