The hidden pandemic: surgical wound complications and the use of technology for early detection and prevention

The global volume of surgery is considerable and growing. It was estimated that 312.9 million surgical procedures were performed in 2012, which represented a 33.6% increase over 8 years. Despite advances in surgical technique, infection control practices and wound care, surgical wound complications such as surgical site infection and surgical wound dehiscence are unwanted outcome following surgery.

Burden of Multidrug-Resistant Gram-Negative Bacterial Infections in a Tertiary Care Hospital

Multidrug-resistant (MDR) Gram-negative bacterial infections have emerged as a major public health concern. The aim of the present study was to detect the rate of infections due to MDR Gram-negative bacteria (GNB) in a tertiary care hospital, the rate of Carbapenemases and AmpC-β-lactamases production and the Antimicrobial susceptibility test pattern (AST) among MDR GNB. The rate of MDR GNB during the study period was 25.70%. Urine samples showed the highest contribution to the total MDR GNB. Among the total MDR GNB isolates, 166 were randomly selected and included in the present study. A higher rate of MDR GNB was reported among male patients (61.5%) compared to the females (38.5%) and most of them were from the patients aged between 61-70 years (30.7%). The most prevalent MDR GNB was Klebsiella pneumoniae 80 (48.12%), followed by Escherichia coli 43 (25.9%). AST of MDR GNB revealed their significant resistance to β-lactamases/β-lactamases inhibitors, cephalosporins, fluoroquinolones and carbapenem drugs (98%). Of 123 MDR Enterobacterales, 83% of them were found to be Metallo β-lactamase (MBLs) producers by mCIM and eCIM methods. Of 43 MDR non-fermenters, 29 (67.4%) of them were found to be carbapenemase producers by MHT. About 29.51% of MDR GNB isolates were found to be AmpC producers by AmpC disk test. A reliable and rapid phenotypic method to detect carbapenemases and AmpC β-lactamases among MDR GNB in a routine microbiology laboratory method is clinically important to guide antibiotic therapy and implementation of effective infection control practices.

Phenotypic and genotypic assessment of fluoroquinolones and aminoglycosides resistances in Pseudomonas aeruginosa collected from Minia hospitals, Egypt during COVID-19 pandemic

BackgroundOne of the most prevalent bacteria that cause nosocomial infections is Pseudomonas aeruginosa. Fluoroquinolones (FQ) and aminoglycosides are vital antipseudomonal drugs, but resistance is increasingly prevalent. The study sought to investigate the diverse mechanisms underlying FQ and aminoglycoside resistance in various P. aeruginosa strains particularly during the COVID-19 crisis.MethodsFrom various clinical and environmental samples, 110 P. aeruginosa isolates were identified and their susceptibility to several antibiotic classes was evaluated. Molecular techniques were used to track target gene mutations, the presence of genes encoding for quinolone resistance, modifying enzymes for aminoglycosides and resistance methyltransferase (RMT). Efflux pump role was assessed phenotypically and genotypically. Random amplified polymorphic DNA (RAPD) analysis was used to measure clonal diversity.ResultsQnrS was the most frequently encountered quinolone resistance gene (37.5%) followed by qnrA (31.2%) and qnrD (25%). Among aminoglycoside resistant isolates, 94.1% harbored modifying enzymes genes, while RMT genes were found in 55.9% of isolates. The aac(6')-Ib and rmtB were the most prevalent genes (79.4% and 32.3%, respectively). Most FQ resistant isolates overexpressed mexA (87.5%). RAPD fingerprinting showed 63.2% polymorphism.ConclusionsAminoglycosides and FQ resistance observed in this study was attributed to several mechanisms with the potential for cross-contamination existence so, strict infection control practices are crucial.

Predictive modeling of mortality in carbapenem-resistant Acinetobacter baumannii bloodstream infections using machine learning.

Acinetobacter baumannii, a notable drug-resistant bacterium, often induces severe infections in healthcare settings, prompting a deeper exploration of treatment alternatives due to escalating carbapenem resistance. This study meticulously examined clinical, microbiological, and molecular aspects related to in-hospital mortality in patients with carbapenem-resistant A. baumannii (CRAB) bloodstream infections (BSIs). From 292 isolates, 153 cases were scrutinized, reidentified through matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS), and evaluated for antimicrobial susceptibility and carbapenemase genes via multiplex polymerase chain reaction (PCR). Utilizing supervised machine learning, the study constructed models to predict 14- and 30-day mortality rates, revealing the Naïve Bayes model's superior specificity (0.75) and area under the curve (0.822) for 14-day mortality, and the Random Forest model's impressive recall (0.85) for 30-day mortality. These models delineated eight and nine significant features for 14- and 30-day mortality predictions, respectively, with "septic shock" as a pivotal variable. Additional variables such as neutropenia with neutropenic days prior to sepsis, mechanical ventilator support, chronic kidney disease, and heart failure were also identified as ranking features. However, empirical antibiotic therapy appropriateness and specific microbiological data had minimal predictive efficacy. This research offers foundational data for assessing mortality risks associated with CRAB BSI and underscores the importance of stringent infection control practices in the wake of the scarcity of new effective antibiotics against resistant strains. The advanced models and insights generated in this study serve as significant resources for managing the repercussions of A. baumannii infections, contributing substantially to the clinical understanding and management of such infections in healthcare environments.

Prevalence of rectal carbapenem resistant Enterobacterales carriage among patients attending healthcare facilities in Ibadan, Nigeria: a descriptive study

BackgroundCarbapenem Resistant Enterobacterales (CRE) infections are increasingly associated with or directly responsible for morbidity and mortality from bacterial infections in sub-Saharan Africa where there are limited antibiotic options. CRE rectal colonization of patients in healthcare facilities provides a reservoir of these organisms and could potentially cause invasive infections in these settings. The prevalence of rectal carriage among patients attending healthcare facilities in Nigeria has not been previously described. We set out to assess the prevalence of rectal CRE carriage and their antibiotic susceptibility patterns among patients attending healthcare facilities in Nigeria.MethodsA descriptive cross-sectional study was carried out from December 2021 to September 2022 in Ibadan, in which patients attending primary, secondary and tertiary healthcare facilities were screened for rectal carriage of CRE by microscopy, culture and sensitivity of rectal swab specimens.ResultsA total of 291 patients were screened; 45 (15.5%), 66 (22.7%) and 180 (61.8%) at primary, secondary and tertiary healthcare facilities, respectively. All but one of them had received a third-generation cephalosporin or carbapenem in the preceding 30 days. The mean age was 28.8 years and 55.7% were male. Overall, 51 (17.5%) participants had CRE colonization, with 5(11.1%), 9(13.6%) and 37(20.6%) at primary, secondary and tertiary healthcare facilities, respectively (p = 0.243). Regarding antimicrobial susceptibility, 43(84.3%) CRE isolates were resistant to at least 3 different classes of antibiotics while two Escherichia coli isolates were resistant to all 5 classes of antibiotics tested. The lowest rates of CRE resistance were to tigecycline (6, 11.5%) and colistin (8, 15.7%).ConclusionsIn this first study on CRE colonization in Nigeria, we found that a substantial proportion of patients in three levels of healthcare facilities had rectal carriage of CRE, including pan-resistant isolates. Active surveillance and appropriate infection prevention and control practices (IPC) need to be urgently strengthened to mitigate the risk of active CRE infection.Trial registrationNot applicable.

Transforming Hospital Housekeeping: The Kayakalp Journey

Introduction The Kayakalp guidelines for public healthcare facilities under the Swachh Bharat Abhiyan (Clean India Mission) focus on improving sanitation, cleanliness, and infection control at public hospitals in India. This study was conducted in a 960-bed tertiary-level teaching hospital in eastern India. Housekeeping has been a challenge in public institutions, with factors like overcrowding and resource constraints. Tobacco and betel nut chewing, spitting, poor sanitation practices, and open urination are major challenges in ensuring sanitation at the hospital. The research objective was to study the implementation of the Kayakalp guidelines for quality improvement in housekeeping services at the institution. Methods A pre- and post-interventional study was conducted using the Plan-Do-Check-Act (PDCA) quality tool. Plan phases included the gap assessment using the Kayakalp checklist with numerical scoring. Necessary interventions were done under three headings: structure, processes, and outcomes in the “Do” phase. The “Check” phase included monitoring of the activities followed by the “Act” phase, which included a review of the action plan. External experts nominated by the government conducted the final assessments and recommended it as one of the cleanest hospitals. Results A 360-degree improvement was observed in hospital services, with assessment score improvement from 73.68% to 95.0%. The institution received the first prize in 2020 and 2021 and runners-up Kayakalp National Award under category “B” (Institute of National Importance) Hospitals in 2019. Conclusion The implementation of Kayakalp guidelines of the Government of India proved to be efficient in the improvement of housekeeping and infection control practices in the institution.

Visual Mapping of Operating Theater Team Dynamics and Communication for Reflexive Feedback and Surgical Practice Optimization.

Effective operating theater (OT) communication and teamwork are essential to optimal surgical outcomes. We mapped the OT team dynamics and infection control practices using visual methods to guide reflexive feedback and optimize perioperative practices. Data were gathered from adult gastrointestinal surgical teams at a tertiary hospital in India using observations, sociograms (communication mapping tool), and focus group discussions (FGDs). Our methods aimed to map team communication, roles and responsibilities in infection-related practices, and door openings. Qualitative data were thematically analyzed. Quantitative data were analyzed using descriptive statistics. Data were gathered from 10 surgical procedures (over 51 hours) using 16 sociograms, 15 traffic flow maps, and 3 FGDs. Senior surgeons directly influence team hierarchies, dynamics, and communication. While the surgeons, anesthetic residents, and technicians lead most tasks during procedures, the scrub nurse acts as a mediator coordinating activity among role players across hierarchies. Failing to provide the scrub nurse with complete details of the planned surgery leads to multiple door openings to fetch equipment and disposables. Traffic flow observed in 15-minute intervals corresponds to a mean frequency of 56 door openings per hour (min: 16; max: 108), with implications for infection control. Implementing the World Health Organization surgical safety checklist was inconsistent across pathways and does not match reported compliance data. Human factors research is important in optimizing surgical teamwork. Using visual methods to provide feedback to perioperative teams on their communication patterns and behaviors, provided an opportunity for contextualized enhancement of infection prevention and control practices.

European society of clinical microbiology and infectious diseases guidelines for antimicrobial stewardship in emergency departments (endorsed by European association of hospital pharmacists)

ScopeThis European Society of Clinical Microbiology and Infectious Diseases guideline provides evidence-based recommendations to support a selection of appropriate antibiotic use practices for patients seen in the emergency department (ED) and guidance for their implementation. The topics addressed in this guideline are (a) Do biomarkers or rapid pathogen tests improve antibiotic prescribing and/or clinical outcomes? (b) Does taking blood cultures in common infectious syndromes improve antibiotic prescribing and/or clinical outcomes? (c) Does watchful waiting without antibacterial therapy or with delayed antibiotic prescribing reduce antibiotic prescribing without worsening clinical outcomes in patients with specific infectious syndromes? (d) Do structured culture follow-up programs in patients discharged from the ED with cultures pending improve antibiotic prescribing? MethodsAn expert panel was convened by European Society of Clinical Microbiology and Infectious Diseases and the guideline chair. The panel selected in consensus the four most relevant antimicrobial stewardship topics according to pre-defined relevance criteria. For each main question for the four topics, a systematic review was performed, including randomized controlled trials and observational studies. Both clinical outcomes and stewardship process outcomes related to antibiotic use were deemed relevant. The literature searches were conducted between May 2021 and March 2022. In April 2022, the panel members were formally asked to suggest additional studies that were not identified in the initial searches. Data were summarized in a meta-analysis if possible or otherwise summarized narratively. The certainty of the evidence was classified according to the Grading of Recommendations Assessment, Development and Evaluation criteria. The guideline panel reviewed the evidence per topic critically appraising the evidence and formulated recommendations through a consensus-based process. The strength of the recommendations was classified as strong or weak. To substantiate the implementation process, implementation trials or observational studies describing facilitators/barriers for implementation were identified from the same searches and were summarized narratively. RecommendationsThe recommendations on the use of biomarkers and rapid pathogen diagnostic tests focus on the initiation of antibiotics in patients admitted through the ED. Their effect on the discontinuation or de-escalation of antibiotics during hospital stay was not reported, neither was their effect on hospital infection prevention and control practices. The recommendations on watchful waiting (i.e. withholding antibiotics with some form of follow-up) focus on specific infectious syndromes for which the primary care literature was also included. The recommendations on blood cultures focus on the indication in three common infectious syndromes in the ED explicitly excluding patients with sepsis or septic shock. Most recommendations are based on very low and low certainty of evidence, leading to weak recommendations or, when no evidence was available, to best practice statements. Implementation of these recommendations needs to be adapted to the specific settings and circumstances of the ED. The scarcity of high-quality studies in the area of antimicrobial stewardship in the ED highlights the need for future research in this field.

Performance and acceptability of the STREAM Disinfectant Generator for infection prevention and control practices in primary health care facilities in Uganda

BackgroundEffective infection prevention and control programs can positively influence quality of care, increase patient safety, and protect health care providers. Chlorine, a widely used and effective chemical disinfectant, is recommended for infection prevention and control in health care settings. However, lack of consistent chlorine availability limits its use. Electrolytic chlorine generators can address limited chlorine supply and stockouts by enabling onsite production of readily usable, high-quality chlorine cost-effectively. We report the feasibility (i.e., performance, acceptability, chlorine availability, and cost) of the electrolytic STREAM Disinfectant Generator (Aqua Research, New Mexico, USA) device for infection prevention and control in primary health care facilities in Uganda.MethodsWe installed STREAM devices in 10 primary health care facilities in central and western Uganda. Commercial chlorine inventory records (stock cards) were reviewed in each facility to calculate average liters of chlorine received and used per month. These values were compared with actual STREAM chlorine production volumes over the study period to determine its impact on chlorine availability. We collected acceptability data from a purposive sample of device users (n = 16), hospital administrators (n = 10), and district health officers (n = 6) who had been directly involved in the operation or supervision of the STREAM device. We descriptively analyzed the acceptability data by user group and evaluated qualitative responses manually using a thematic approach. Cost data were normalized and modeled to determine a break-even and cost-savings analysis across a five-year period (the minimum expected lifespan of the STREAM device).ResultsChlorine was consistently available without any reported stockouts during the evaluation period. STREAM chlorine production resulted in a 36.9 percent cost-savings over a five-year period compared to commercial chlorine. User acceptability of the STREAM device was high among STREAM operators, hospital administrators, and district health officers, with all respondents reporting that STREAM moderately or significantly improved infection prevention and control practices in the health facility. Overall, 88 percent of device users and 100 percent of hospital administrators wished to continue using the STREAM device instead of commercial chlorine products.ConclusionThe STREAM device has demonstrated significant potential to strengthen infection prevention and control practices in health care facilities in Uganda. Based on the preliminary results, the STREAM device should be considered a promising tool for district hospitals and large health centers facing infection prevention and control challenges in Uganda and elsewhere, provided water and electricity are available. Going forward, implementation of the STREAM device could also be considered in smaller health care facilities in Uganda and elsewhere.

Incidence density rate of multidrug-resistant organism (MDRO) at a tertiary care teaching hospital: A retrospective cross-sectional study

: Multidrug-resistant organisms (MDROs) has become a major public health concern. Rise of MDROs and their negative consequences on patient’s survival and health care costs need the assessment of their burden and implementation of practices to control their emergence and spread. There is a lack of literature mentioning incidence density rates (IDR) of various MDRO infections in Indian hospitals. Therefore, the study was conducted to determine the infection IDR and trend of various MDROs at a tertiary care teaching hospital. It will serve as a benchmark data for similar facilities using the same surveillance definitions and methodology. : A retrospective cross-sectional study was conducted using culture data of ten years (January 2014 to December 2023) at Shree Krishna Hospital, Karamsad. MDRO studied included Methicillin-resistant (MRSA), V (VRE), (CRE), Multidrug-resistant (MDR) spp. and MDR . A total of 7311 MDRO were detected from 1321793 in-patients, showing the overall IDR of 5.53 per 1000 patients-days. CRE (n = 3056, 42%) was the most common MDRO. The overall IDR per 1000 patient-days of MRSA, VRE, CRE, MDR- ., and MDR- was 0.81, 0.23, 2.31, 1.29 and 0.89 respectively. Overall MDRO IDR has increased from 4.20 to 8.77 from 2014 to 2023. An increasing IDR was observed for MRSA (0.57 to 1.48) and MDR- (0.43 to 1.60). Around 80% of the . were MDR as compared to other MDRO. MDROs have been identified as a significant problem at our institute showing an increasing trend. We recommend following stringent infection control practices including isolation protocols as well as adherence to hospital antibiotic policy to reduce the burden of MDROs.

Exploring veterinary students' awareness and perception of zoonoses risks, infection control practices, and biosecurity measures in Ethiopia.

Universities and colleges are often regarded as playing a key role in educating veterinarians and animal health workers who advise farmers on herd health and animal husbandry. However, to date, studies examining veterinary students' knowledge of zoonotic diseases of public health importance and the source of this knowledge, as well as their preparedness to respond to these diseases, have focused on the Global North rather than the Global South. This study takes Ethiopia as a case study in exploring veterinary medicine students' knowledge of zoonosis risks, infection control practices and biosecurity measures, recognizing that it is imperative to reconcile national-level veterinary education curricula with emerging global trends, such as One Health-focused training. This training advocates for a collaborative, interdisciplinary response at local, national, and international levels to the adverse impact of zoonotic diseases on animal health and productivity, and human and environmental health. Data for this study were collected through a pre-tested online questionnaire administered to 154 veterinary students from several universities in Ethiopia. The findings of this study suggest veterinary students were aware of the public health risks posed by zoonoses and the important role that collaboration between the disciplines of human and animal health can play in addressing zoonoses and emerging health risks. However, students demonstrated poor knowledge of the need to adopt infection control measures (ICPs) and biosecurity measures to reduce occupational risks and prevent within and between herd transmission of infection. Moreover, students' vaccination rates against zoonotic diseases associated with occupational risks, such as rabies, were low. The results of this study suggest that there are currently gaps in Ethiopia's veterinary curriculum and that enhancing veterinary students' access to information regarding infection control practices and biosecurity measures could contribute to reducing their future occupational exposure to zoonoses. This study highlights the policy implications of the current veterinary medicine curriculum in Ethiopia and the scope for aligning the curriculum with important global initiatives, such as One Health-focused training.

Associations of Plasmodium and Intestinal Helminth Infections with Maternal Anemia and Adverse Pregnancy Outcomes in Northwest Ethiopia.

Malaria and intestinal helminth infections are significant public health challenges in Ethiopia. However, little is known about the relationship of Plasmodium and intestinal helminth infections in pregnancy with maternal anemia and adverse pregnancy outcomes. A health-facility-based cross-sectional study was conducted among 526 parturients in northwest Ethiopia to investigate the associations of these parasitic infections with anemia and adverse pregnancy outcomes. Maternal and newborn profiles were collected using questionnaires and checklists. Maternal hematocrit was determined using the micro-hematocrit method. Malaria was diagnosed by microscopy, rapid diagnostic tests, and quantitative polymerase chain reaction, whereas intestinal parasites were detected microscopically using stool wet mount and Kato-Katz preparations. Among the women, 38.6% were anemic, and 36.5% had adverse pregnancy outcomes. Single infections of hookworm (adjusted odds ratio [aOR] = 3.11, 95% CI: 1.64-5.87) in pregnancy were associated with anemia at parturiency, whereas malaria single infections were associated with anemia (aOR = 4.28, 95% CI: 2.17-8.23) and adverse pregnancy outcomes (aOR = 2.94, 95% CI: 1.47-5.91). Moreover, intestinal helminth coinfections in pregnancy were associated with anemia (aOR = 13.3, 95% CI: 4.8-36.8), whereas malaria-helminth coinfections were associated with anemia (aOR = 7.47, 95% CI: 3.71-15.04) and adverse pregnancies (aOR = 4.75, 95% CI: 2.36-9.57). Overall, the study showed that Plasmodium and intestinal helminth infections in pregnancy are associated with anemia and adverse pregnancy outcomes. Thus, strengthening malaria and intestinal parasite infection prevention and control practices in pregnancy is warranted to alleviate the burden of anemia and adverse pregnancy outcomes.

Infection prevention, control and management: assessing the knowledge among nurses and student nurses in the Eastern Province of Sri Lanka

Background and aims: The knowledge of infection control among health-care workers is a crucial factor in the success of infection control pro-grams. This study compares the understanding of infection control and prevention practices among nurses and student nurses in eastern province of Sri Lanka. Methods: We utilized a pre-tested self-administered questionnaire with 25 questions. Descriptive statistics and the independent t-test were used to analyze survey responses and compare scores between groups. Results: Out of 178 responses analyzed 112 were nurses and 66 were student-nurses. The average scores were 44% for nurses and 51% for student-nurses. Both groups had less than 10% knowledge of notifiable diseases in Sri Lanka and medical abbreviations. Knowledge about immunization, vaccines, clinical sample transportation, and MRSA decolonization was under 40% for both groups. Overall knowledge of infection control and prevention practices among nurses was significantly poorer than that of student-nurses (p<0.001). Conclusion: These findings underscore the generally inadequate knowledge of infection control and prevention practices among both nurses and student-nurses. It is imperative to implement policies and measures to as-sess and enhance the training curricula for student-nurses and to ensure ongoing training programs for nurses.

Long-Term Sustainability of Peri-Operative Infection Control Practices: Implementation of "Clean Cut," a Checklist-Based Quality Improvement Program in India.

Introduction: Surgical site infections (SSIs) are a substantial healthcare burden in low- and middle- income countries. "Clean Cut" is a checklist-based infection prevention and control (IPC) program intended to improve compliance to peri-operative IPC standards. We aim to study the short-term and long-term impact of its implementation in a tertiary care cancer referral center. Methods: This was a single institute, prospective interventional study. Patients undergoing elective head-neck surgical procedures were included. The "Clean Cut" program consisting of surveillance, audits, and IPC training was implemented for 6 months, after which there was no active oversight. Post-intervention (T2) and 1-year follow-up (T3) data regarding compliance to core IPC practices and SSI rates were compared with baseline (T1). Results: One hundred eighty six patients were included with 50 (26.9%), 86 (46.2%), and 50 (26.9%) patients at T1, T2, and T3, respectively. At baseline, teams complied with a mean of 3.56 of the six critical components of infection control processes which rose to 4.66 (p < 0.001) at T2, but decreased to 4.02 at T3 (p = 0.053). The SSI rate at baseline decreased significantly after Clean Cut implementation [16 (32%) vs. 12 (13.95%), p = 0.012], but returned to baseline levels after 1 year [17 (34%), p = 0.006]. Conclusion: Implementation of the "Clean Cut" program increases compliance to infection control processes and reduces SSI rates in the short term. Without continuing oversight, these rates return to baseline values after 1 year.

Clusters of emerging multidrug-resistant organisms in US health care facilities during the initial months of the SARS-CoV-2 pandemic

Outbreaks of emerging multidrug-resistant organisms (eMDROs), including carbapenem-resistant Enterobacterales, carbapenem-resistant Acinetobacter baumannii, and Candida auris, have been reported among severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) patients. We describe eMDRO clusters in SARS-CoV-2 units and associated infection control (IC) practices early in the SARS-CoV-2 pandemic. We conducted a retrospective survey of a convenience sample of health departments in 11 states to describe clusters of eMDROs that began before November 1, 2020 and involved SARS-CoV-2 units. Cluster characteristics and IC practices during the cluster period were assessed using a standardized outbreak report form, and descriptive analyses were performed. Overall, 18 eMDRO clusters (10 carbapenem-resistant Enterobacterales, 6 Cauris, 1 carbapenem-resistant Pseudomonas aeruginosa, and 1 carbapenem-resistant A baumannii) in 18 health care facilities involving 397 patients were reported from 10 states. During the cluster period, 60% of facilities reported a shortage of isolation gowns, 69% extended use of gowns, and 67% reported difficulty obtaining preferred disinfectants. Reduced frequency of hand hygiene audits was reported in 85% of acute care hospitals during the cluster period compared with before the pandemic. Changes in IC practices and supply shortages were identified in facilities with eMDRO outbreaks during the SARS-CoV-2 pandemic and might have contributed to eMDRO transmission.

Infection Prevention and Control in the Emergency Department Unit in King Khalid Hospital, Hail City, Saudi Arabia

Context: The emergency department presents unique challenges to infection control and prevention. Infection control (IC) activities include the identification of infectious disease processes, surveillance, and epidemiologic investigation, preventing/controlling the transmission of infectious agents/healthcare-associated infections, employee/occupational health, management and communication, education and research, managing the environment of care, and cleaning, sterilization, disinfection, and asepsis. Aim: Assess infection prevention and control practices in the emergency department in King Khalid Hospital, Hail City, Saudi Arabia. Methods: A quantitative, descriptive correlational study design was used to conduct the study in the emergency department (ED) unit at King Khalid Hospital (KKH), Hail City, Saudi Arabia. All available nurses working in the emergency department KKH at the time of data collection. A self-administered structured questionnaire was utilized to collect data in the current study. Results: 71.7% (n=76) of the participants were between 25 and 35 years old, 24.5% (n=26) were between 36-45 years old, and only 3.8% (n=4) were over 45 years old. 79.2% of the nurses reported that there is a curriculum or program for IC training for doctors and nurses, 71.7% mentioned that they have recommendations for IC training link doctors and nurses, 84.8% reported that IC issues are parts of the examination and evaluation in basic training for nurses, and there are policies and procedures elaborating infection control interventions. Besides, 82.1% of the nurses reported infection control policies and guidelines in their units, and 83% and 82.7% stated that there is a list of reportable infectious agents available in their unit and accessible to all staff, and there is an active infection control team, respectively. Conclusion: Overall, this study indicated that nurses reported a high level of infection prevention and control practices in the ED of King Khalid Hospital. There was no statistically significant association between nurses' knowledge of infection prevention and control practices and their demographic characteristics. Implementing regular training and educational programs for nurses, focusing on updating knowledge and skills in IPC practices, was recommended.

Candida auris Response in a Tennessee Dialysis Facility, 2023

Background: Candida auris, a multi-drug resistant fungal pathogen, was introduced to Tennessee in 2021. There are limited studies on the spread of C. auris in highly specialized care settings including outpatient dialysis facilities. Facilities are concerned that C. auris transmission is difficult to prevent in this setting due to patient vulnerability, treatment frequency and length, and isolation challenges. As a result, these facilities may reject patients based on their positive colonization status. In 2023, the Tennessee Department of Health (TDH) conducted two containment-driven colonization screenings in response to a colonized patient receiving dialysis treatment for one month without their status being known to the facility. Methods: An initial point prevalence survey (PPS) was conducted to assess for ongoing transmission among dialysis patients. Patient screening was prioritized for the cohort of patients who received dialysis at the same time as the index patient (Cohort A). The screening was broadened to include patients dialyzed directly before Cohort A (Cohort B) by request of the Cohort B patients. A second PPS was conducted 7 weeks later, targeting the same cohorts. Specimens were collected through supervised patient self-collection of a skin swab from the axilla and groin. Flocked Eswabs were used for collection and transferred in Amies transport media to the Tennessee State Public Health Lab. The presence of C. auris was detected via Polymerase Chain Reaction (PCR). Results: Twenty-three patients (12 from Cohort A; 11 from Cohort B) were screened in the first PPS. One patient from Cohort A tested positive. This colonized patient was determined to be a known C. auris case first detected four months prior, but the patient’s status was never communicated to the dialysis facility from the discharging acute care facility. Eleven patients, excluding the previously identified positives, participated (9 from Cohort A; 2 from Cohort B) in the second PPS; no positives were identified. Discussion: The index patient and an additional patient identified by the PPS both received dialysis at this facility for up to 4 months without facility knowledge. These results suggest that the standard infection control practices at this dialysis facility were adequate to prevent the transmission of C. auris among dialysis patients on multiple shifts. Additionally, patient self-collection identified a known C. auris patient. Future TDH work includes further evaluating the risk of C. auris transmission and developing targeted infection prevention and control practices for the outpatient dialysis setting.

Study on Knowledge of Infection Control Practice of Healthcare Workers

ABSTRACT Background: Healthcare-associated infections (HAIs), also known as nosocomial infections, are a significant risk in hospitals, leading to increased morbidity and mortality among patients due to poor hygiene practices. Materials and Methods: This descriptive study involved 350 participants from Wuhan’s private hospitals. Respondents answered a questionnaire distributed in person or via email, and data were analyzed using SPSS version 25.0. Results: Analysis revealed a knowledge gap among healthcare workers in infection control, affecting their ability to maintain hospital cleanliness. Education levels were assessed, showing that 60% of participants held diplomas or higher qualifications. Conclusion: The study highlights the urgent need for enhanced training and information dissemination on infection control practices among healthcare staff. Identifying this knowledge and practice gap is crucial for improving hospital hygiene and reducing HAI incidence.

Outbreak of New Delhi Metallo-β-lactamase-producing Escherichia coli in a Neonatal Intensive Care Unit, New York State

Background: Outbreaks of carbapenemase-producing (CP) organisms (CPOs), including carbapenem-resistant Enterobacterales (CRE), in neonatal intensive care units (NICUs) are not well documented. The Centers for Disease Control and Prevention (CDC) identifies CP-CRE as an urgent threat to United States (US) healthcare facilities. Wadsworth Center, the New York State (NYS) Department of Health’s (NYSDOH’s) public health laboratory, participates in CDC’s Antimicrobial Resistance Laboratory Network to provide CPO identification, characterization, and surveillance. NYSDOH investigated an outbreak of CP-CRE Escherichia coli (E. coli) infections in NICU patients reported by one hospital. Method: Hospital A reported a CRE E. coli outbreak in their NICU to NYSDOH, as required by NYS Sanitary Code. In response, epidemiologists reviewed case data, conducted case finding, and provided infection control guidance to the hospital. Hospital A continued NICU clinical surveillance and conducted colonization screening to detect additional cases of CRE E. coli. The Wadsworth Center Antimicrobial Resistance Laboratory Network tested isolates from affected patients for CP genes and performed whole genome sequencing (WGS) to determine the CP gene variant, multilocus sequence type (MLST), and relatedness by mutation event (ME) analysis. NYSDOH epidemiologists assessed Hospital A’s infection control practices in affected areas and provided recommendations. Result: Hospital A identified two CRE E. coli infections in NICU patients with overlapping admissions in June-July 2023. Retrospective surveillance identified a third CRE E. coli case in an adult medical intensive care unit patient on admission to Hospital A in June 2023, with prior hospitalization April-May 2023. WGS analysis identified the blaNDM-5 gene in all three CRE E. coli patient isolates. The two NICU patients’ isolates had the same MLST (361/650) and differed by 9 MEs, indicating relatedness to each other and not the adult patient’s (MLST 167/2). NICU patient colonization screening identified no additional blaNDM-5 E. coli cases.
