Research progress on knowledge-attitude-practice of VTE prevention in hospitalized patients: A review.

This study analyzes and summarizes the assessment tools, current situation, and influencing factors of venous thromboembolism (VTE) prevention knowledge, attitudes, and practices (KAP) among patients. This study aimed to provide a reference basis for developing targeted health education plans and intervention strategies for patients to improve their knowledge and beliefs concerning VTE prevention. This study aimed to increase the implementation rate of VTE prevention measures and ultimately reduce the incidence of VTE.The current studies found that the factors influencing knowledge, attitude, and practice of VTE prevention in hospitalized patients include demographic factors (age, sex, education level, occupation), disease-related factors (treatment stage, injury site, and wards), and other factors (receiving VTE-related knowledge education and having medical workers at home).

Use of a risk-based intervention bundle to prescribe and implement interventions to prevent pressure injury: An observational study.

To explore the relationship between the prescription and implementation of pressure injury preventative interventions following risk assessment combined with a risk-stratified intervention bundle. Single-centre, cross-sectional, observational, prospective. The charts and bedsides of 341 adult inpatients were examined. Data collection included pressure injury risk level, prescribed preventative interventions and evidence of intervention implementation. Most patients (68.6%) were at risk of pressure injury, and most interventions were prescribed according to their risk level. However, evidence from direct observation and/or documentation indicated intervention implementation rates were relatively poor. Of nine interventions mandated for all patients, compliance with three patient-/carer-focused interventions was particularly poor, with evidence indicating they had been implemented for 3%-10% of patients. Also, nutritional screening-related interventions were implemented poorly. Clinically indicated implementation of heel-elevation devices and bariatric equipment was low for at-risk patients, and the implementation of interventions for patients with existing pressure injuries was suboptimal. Significant proportions of several interventions that were observed as having been implemented were not documented as such. While most interventions were prescribed according to patient risk level, the overall implementation of interventions was poor. However, the results may in part be due to failure to document interventions as opposed to omitting them. Documentation of interventions is crucial as it provides evidence of the care provided. An increased focus on documentation of pressure injury preventative interventions is required, with a clear distinction between prescription and implementation. The results highlighted several deficiencies in care, particularly relating to evidence of implementation, patient involvement and nutritional screening. The results from this study will be used to inform and improve future pressure injury prevention practice within the study hospital and should be used to inform and benchmark pressure injury preventative practices in other hospitals. The study adheres to STROBE guidelines. None.

Association between the C-reactive protein-triglyceride glucose index and erectile dysfunction in US males: results from NHANES 2001-2004.

The C-reactive protein-triglyceride glucose index (CTI) is emerging as a novel indicator for comprehensively assessing the severity of both inflammation and insulin resistance. However, the association between CTI and erectile dysfunction (ED) remains largely unexplored. Participant data for this study were sourced from NHANES 2001-2004, with exclusion criteria applied to those lacking information on clinical variables. The CTI was defined as 0.412*Ln (CRP) + ln [T.G. (mg/dL) × FPG (mg/dL)/2]. Weighted univariable and multivariable logistic regression models were utilized to examine the correlation between the CTI and ED, assessing the CTI as both a continuous and categorical variable (quartile). Moreover, subgroup analyses were conducted to pinpoint sensitive populations, and interaction analysis was performed to validate the findings. A total of 1502 participants were included in the final analysis, encompassing 302 with ED and 1200 without ED. After adjusting for potential confounders, the CTI was positively associated with ED incidence (OR = 1.56, 95% CI: 1.27-1.90, P = 0.002). The fourth quartile of the CTI significantly increased the incidence of ED (OR = 2.69, 95% CI: 1.07-6.74, P = 0.04), and the lowest quartile of CTI was used as the reference. The dose-response curve revealed a positive linear relationship between the CTI and the incidence of ED. Subgroup analysis confirmed the consistent positive relationship between the CTI and ED. The interaction test indicated no significant impact on this association. Finally, a sensitivity analysis was performed to verify the significant positive correlation between the CTI and severe ED (OR = 1.44, 95% CI: 1.19-1.76, P = 0.004). Our national data indicate that a greater CTI is positively linked to an increased risk of ED in US men, suggesting its potential for use in clinical practice for ED prevention or early intervention. Additional large-scale prospective studies are warranted to substantiate the causative relationship between CTI and ED.

“You Have to Humanize Your feelings:” Black fathers’ Reflections on How Youth Violence Prevention and Perpetration Influence Their Overall Health and Fathering Practices

ABSTRACT In Baton Rouge, LA, and nationally, youth violence is a serious public health problem affecting the lives of community members. Fortunately, Black fathers have responded to the urgent call to prevent youth violence in Louisiana. In 2021, the SUPPORT project was launched to unearth stories of Black fathers’ prevention practices and interventions. Since relationships are embedded within and across various systems, the Social-Ecological Model for Violence Prevention was applied to a semi-structured interview approach to investigate two aims with 12 Black fathers from Baton Rouge: (1) how their experiences with youth violence influence their mental and social health, and their children’s violence exposure, and (2) the benefits of addressing youth violence. Using Braun and Clarke’s (2021) thematic analysis, the three major themes that emerged related to Black fathers’ history with violence were: (1) self-reflexive moments on lessons learned, (2) the impacts of victimization and bullying, and (3) socioemotional responses to youth violence. Related to the second aim, the salutary impact on the neighborhood and improvement of the school community were the major themes that emerged regarding the perceived benefits of addressing youth violence. These findings demonstrate that interviewees are cognizant of how their history of violence led to maladaptive coping mechanisms in response to youth violence and influenced their fathering ideologies; moreover, they were concerned with familial betterment. Further research is needed to deepen understanding of how Black fathers’ socioemotional responses to youth violence impact their wellness and fathering practices as their children mature.

Comprehensive Risk Assessment of Farmer Households in Flood and Earthquake Prone Areas Based on Multidimensional Information Diffusion Model

In recent years, the global practice of regional natural disaster reduction and comprehensive risk prevention has promoted the integration of multiple disciplines, and the theory and technology of comprehensive risk assessment for multiple natural disaster chains urgently need innovation. This article is based on multiple natural disaster chain scenarios and sets secondary indicators for multiple influencing factors based on the first level indicators composed of basic risk factors such as hazard factors, vulnerability of disaster bearing bodies, and disaster prevention and reduction capabilities. By using multidimensional information diffusion technology, multiple hazard factor hazard combination factors, vulnerability combination factors of disaster bearing bodies, and comprehensive disaster prevention and reduction capability combination factors reflecting various natural disaster scenarios are constructed, A household comprehensive risk assessment index system for multi-dimensional information diffusion assessment of natural disaster comprehensive risk was designed by quantifying risk factors such as the intensity of comprehensive disaster causing factors, vulnerability of disaster bearing bodies, and comprehensive disaster prevention and reduction capabilities in disaster scenarios. This paper expands the traditional information diffusion comprehensive risk assessment model, makes up for the lack of information on geographical units, establishes a multi impact factor multi dimension natural disaster risk comprehensive assessment model for multi risk factors of complex disaster scenarios with small samples, obtains the theoretical value of multi-dimensional information Diffusion model comprehensive risk assessment for complex disaster scenarios, breaks through the sample size limit of natural disaster risks, and makes up for the lack of information on small samples of small probability events, Improved the reliability and accuracy of comprehensive risk assessment for multiple natural disaster chains. Then, take the disaster scenario formed by the comprehensive risk of earthquake and flood in a place in the upper reaches of the Fujiang River basin as the analysis sample, calculate the comprehensive risk assessment value of flood and earthquake damage in the study area's micro samples (rural households in villages and towns). By comparison, it is found that the comprehensive risk value assessed by the multi-dimensional information Diffusion model has good reliability and high accuracy, which is significantly better than the traditional Kriging interpolation method and geographical weighted regression method. This article provides a comprehensive risk assessment of natural disasters at the micro household level, which can better reflect the diversity and regionality of risks, help clarify the hidden risks of rural natural disasters, and provide scientific basis for government emergency management decision-making.

Preoperative Evidence-Based Practice for Prevention of Early Postoperative Infections in Patients Receiving a Liver Transplant.

BACKGROUND This study aimed to evaluate the effectiveness of implementing evidence-based preoperative nursing interventions in reducing postoperative infections and intensive care unit (ICU) length of stay among liver transplant recipients. MATERIAL AND METHODS A controlled study was conducted, comparing postoperative outcomes between an intervention group receiving standardized, evidence-based preoperative care and a control group receiving routine preoperative care. Patients undergoing elective liver transplantation from September 2020 to March 2021 were included and assigned to either the intervention or control group. The intervention group received preoperative interventions based on best available evidence, while the control group received standard preoperative care. The primary outcomes measured were postoperative infection rates and length of ICU stay. RESULTS In the control group the overall Intensive Care Unit (ICU) length of stay was 3 days and the infection rate was 33.30%, while in the intervention group it was 3 days and 13.80% (P<0.05). There was no significant difference in the length of ICU stay between the control and the intervention groups (P>0.05). There was a significant improvement in the awareness, acceptance, and compliance of doctors and nurses. CONCLUSIONS Using the best evidence-based intervention for preoperative nursing of liver transplantation patients can standardize preoperative nursing behavior. Although we did not find significant differences in outcomes before and after the intervention, it is necessary to prevent postoperative infection and improve nursing compliance.

Preventive, Curative, and Tolerance Practices: Family Farmers' Local Ecological Knowledge regarding Harmful Crop Arthropods in NW Patagonia

Family farming systems face the challenge of carrying out their activities alongside Harmful Arthropods (HA), which cause damage to edible, wild, and cultivated plants that are fundamental for farmers. This case study, with farmers from the Nahuel Huapi Family Farmers Free Fair (FFAFNH, Spanish acronym), shows some distinctive elements of Local Ecological Knowledge about HA (LEKHA). LEKHA investigated about seven HA among farmers regarding nomenclature, characterization, ecological aspects, cultivated species affected, ways of acquiring and transmitting knowledge, management practices, and HA's importance. Discussed how these aspects allow us to infer the hybrid character of LEKHA, which articulates traditional knowledge of peasant agriculture and Scientific Technical Knowledge (STK). A participatory workshop was carried out, which emerged as a request and demand from the members of the FFAFNH. Fifteen local names were registered, two of which were Mapuche. Most of the HA are recognized as harmful to more than one plant, and the majority (60%) have been with farmers for a long time. Regarding management, preventive practices predominated (57%) over curative practices (14%). We postulated a new HA management practice, "tolerance" (29%), which implies that HA coexist with people in their productive spaces and are deliberately allowed to follow their natural cycles. The predominant ways of acquiring and transmitting knowledge are idiosyncratic and oblique (35% each). The workshop was an instance of reinforcement and self-validation of LEKHA, where a dialogue of knowledge was established back and forth with the STK.

Slow recovery rates and spatial aggregation of Triatoma infestans populations in an area with high pyrethroid resistance in the Argentine Chaco

BackgroundThe emergence of pyrethroid resistance has threatened the elimination of Triatoma infestans from the Gran Chaco ecoregion. We investigated the status and spatial distribution of house infestation with T. infestans and its main determinants in Castelli, a municipality of the Argentine Chaco with record levels of triatomine pyrethroid resistance, persistent infestation over 2005–2014, and limited or no control actions over 2015–2020.MethodsWe conducted a 2-year longitudinal survey to assess triatomine infestation by timed manual searches in a well-defined rural section of Castelli including 14 villages and 234 inhabited houses in 2018 (baseline) and 2020, collected housing and sociodemographic data by on-site inspection and a tailored questionnaire, and synthetized these data into three indices generated by multiple correspondence analysis.ResultsThe overall prevalence of house infestation in 2018 (33.8%) and 2020 (31.6%) virtually matched the historical estimates for the period 2005–2014 (33.7%) under recurrent pyrethroid sprays. While mean peridomestic infestation remained the same (26.4–26.7%) between 2018 and 2020, domestic infestation slightly decreased from 12.2 to 8.3%. Key triatomine habitats were storerooms, domiciles, kitchens, and structures occupied by chickens. Local spatial analysis showed significant aggregation of infestation and bug abundance in five villages, four of which had very high pyrethroid resistance approximately over 2010–2013, suggesting persistent infestations over space-time. House bug abundance within the hotspots consistently exceeded the estimates recorded in other villages. Multiple regression analysis revealed that the presence and relative abundance of T. infestans in domiciles were strongly and negatively associated with indices for household preventive practices (pesticide use) and housing quality. Questionnaire-derived information showed extensive use of pyrethroids associated with livestock raising and concomitant spillover treatment of dogs and (peri) domestic premises.ConclusionsTriatoma infestans populations in an area with high pyrethroid resistance showed slow recovery and propagation rates despite limited or marginal control actions over a 5-year period. Consistent with these patterns, independent experiments confirmed the lower fitness of pyrethroid-resistant triatomines in Castelli compared with susceptible conspecifics. Targeting hotspots and pyrethroid-resistant foci with appropriate house modification measures and judicious application of alternative insecticides with adequate toxicity profiles are needed to suppress resistant triatomine populations and prevent their eventual regional spread.Graphical

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.

Nurses' experiences of hospital‐acquired pressure injury prevention in acute healthcare services in Victoria, Australia: A qualitative study using the Theoretical Domains Framework

AbstractWe investigated nurses' experiences of hospital‐acquired pressure injury (PI) prevention in acute care services to better understand how PI prevention may be optimised. We used the Theoretical Domains Framework to systematically identify barriers and enablers to evidence‐based preventive practices as required by the International Guideline. This study was one element of a complex capacity building project on PI surveillance and prevention within the acute health service partners of Monash Partners Academic Health Science Centre, an accredited academic health partnership located in Melbourne, Australia. We adopted a qualitative descriptive design. We interviewed 32 nurses that provided care in intensive care units, general wards and COVID wards of four acute care services. Nurses were recruited from four large acute care services (three public, one private) located in Melbourne. Most of them worked with patients who were at high risk of hospital‐acquired PI on a daily basis. Interview transcripts were coded and analysed using thematic analysis guided by the Theoretical Domains Framework. The domains referred to most frequently by all participants included: Knowledge, Skills, Social/Professional Role and Identity, Beliefs about Capabilities, and Environmental Context and Resources. The key barriers discussed by nurses included gaps in nurses' knowledge and skills related to identification and staging of PI, heavy nursing workload and inadequate staffing levels, stigma and self‐blame related to PI identification, and exacerbating impacts of the COVID‐19 pandemic. Main facilitators discussed were training programmes, nursing audits and feedback, and teamwork. Participants suggested improvements including accessible and tailored training, visual reminders, and addressing heavy workloads and emotional barriers nurses face. Investing in tailored training initiatives to improve nurses' knowledge and organisational changes to address low level staffing and heavy workloads are urgently needed to support nurses in delivering optimal care and preventing hospital‐acquired PI.

Investigation of a Donor-derived Carbapenamase-producing Carbapenem-resistant Enterobacterales Hospital Outbreak

Carbapenamase-producing carbapenem-resistant Enterobacterales (CP-CRE) is an urgent public health threat for healthcare facilities. Solid organ transplant (SOT) recipients carry an increased risk for CRE infection and colonization due to prolonged exposures to antimicrobials, healthcare facilities and immunosuppression. CRE infection in SOT patients is associated with an increase in morbidity and mortality. Here, we describe a hospital outbreak investigation of three cases of New Delhi metallo-beta-lactamase (NDM) - CRE that led to novel findings with implications for further interdisciplinary investigations. An NDM-CRE infection in a critically-ill patient was identified during passive surveillance and prompted an investigation. Previous CP-CRE passive surveillance cases were reviewed. Rectal screening was performed for potentially exposed patients. 403 rectal swabs were tested for carbapenemase genes in active surveillance. Patients identified to have a new NDM-CRE isolate on active or passive surveillance were considered cases and underwent in-depth chart review including possible patient-to-patient exposures, hospital locations, procedures, devices, and consultations. NDM-CRE isolates were sent to the Minnesota Department of Health (MDH) for whole genome sequencing (WGS) to assess relatedness. Five NDM-CRE cases were identified, with all isolates harboring blaNDM including three NDM-Klebsiella pneumoniae (NDM-KP) cases (Figure 1). The first NDM-KP case, patient 1, developed mediastinal infection following lung transplantation. Review of United Network for Organ Sharing revealed that respiratory specimens from patient 1’s donor grew NDM-KP and a bronchial wash at the time of transplant yielded NDM-KP. The second NDM-KP case (patient 3) developed ventilator-associated pneumonia and was found to have used sequentially the same ventilator as patient 1. The third NDM-KP case (patient 4) was detected via rectal swab in active surveillance and shared wound care personnel in common with patients 1 and 3 (Figure 2). WGS demonstrated two single nucleotide polymorphisms (SNP) among all three isolates, strongly suggesting relatedness (Figure 3). Best practices for infection prevention were reviewed with wound care personnel. To date, no further NDM-KP isolates have been identified. Investigation was facilitated by in-depth chart review and WGS via the Central Region Antimicrobial Resistance Laboratory Network at MDH. Detection of the NDM-KP from a lung donor specimen appears genetically linked to clinical isolates in other patients, raising the possibility of a donor-derived hospital outbreak. This investigation is the first to describe a donor-derived NDM outbreak in a healthcare facility. Communication between organ procurement agencies, transplant centers, and infection prevention must be optimized to prevent CRE-associated morbidity in SOT receipts and CRE hospital outbreaks.

Hospital-Onset Clostridioides difficile infection in chronic kidney disease patients

Introduction: Hospital-onset Clostridioides difficile infection (HO-CDI), reported as laboratory-identified (LabID) event, is common in patients with chronic kidney disease (CKD), especially those with end-stage renal disease (ESRD), and is associated with prolonged length of hospitalization and more severe disease. CKD patients are at increased of developing CDI due to frequent antimicrobial and healthcare exposures. The objective of this study was to assess recent trends of HO-CDI in patients on a nephrology unit at our academic, tertiary care institution. Methods: Retrospective cross-sectional study of patients with HO-CDI who were hospitalized on a nephrology unit between January 2021 to December 2023. Collected variables included: demographic data, characterization of HO-CDI risk factors, infection and diagnosis (including prior history of CDI, toxin versus nucleic acid amplification test [NAAT] positivity, number of loose stools), CDI rate (defined as CDI count/patient days x1000), standardized antimicrobial administration ratio (SAAR) for high-risk for CDI antimicrobials (defined by the National Healthcare Safety Network), and infection prevention and control (IPC) practices, including hand hygiene audit rates. Results: A total of 30 HO-CDI infections were reported on the nephrology unit [Table], with 8 occurring in 2021, 5 in 2022, and 17 in 2023. The median age of patients was 70.8 (range: 37-96) years, and most patients (57%) were female. The majority of patients were admitted from home (73%), and two patients (7%) had a history of CDI in the last 6 months. Among the CDI cases, 60% were NAAT positive and toxin negative, and only 50% had &gt;3 bowel movements (BM) within 24 hours prior to the positive test. Ten percent received promotility agents prior to testing. Most cases (77%) occurred when other CDI patients were on the unit. Hand hygiene compliance rates averaged 81% over the three-year period [Figure 1A]. Eight-four per cent of patients received antibiotics within 30 days of CDI diagnosis; SAAR was &gt;1 for quarters 2 and 4 in 2022, and quarter 1 in 2023 [Figure 1B]. Conclusion: On our nephrology unit, patients often had &lt; 3 BM within 24 hours of CDI diagnosis, and 60% of cases were toxin-negative, NAAT-positive, suggesting possible C. difficile colonization, rather than true infection. In addition, an elevated SAAR correlated with high CDI rates. Multicomponent interventions may be required to reduce the rates of HO-CDI in CKD patients. Opportunities include emphasis on diagnostic and antimicrobial stewardship, environmental cleaning and adherence to IPC practices, including hand hygiene.

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.

Risk Factors and Outcomes of Candida auris in Southeast Michigan

Background: Candida auris is an emerging multidrug resistant fungus that presents a serious global health threat and causes severe infections with a high mortality rate in hospitalized patients with significant underlying comorbidities. We describe the risk factors and clinical outcomes associated with C. auris in Southeast Michigan. Methods: This is a retrospective case series of culture-positive C. auris patients who had contact with our healthcare facility in Detroit from 2021 to 2023. We evaluated demographics, comorbidities, risk factors, and outcomes. A comparative analysis of colonized and infected patients was performed. Results: Forty-eight (81%) colonized and 11 (19%) infected patients were included (Table); 70% were male with median age of 66 years. All variables were comparable between the two groups except chronic kidney disease, which was significantly more prevalent among colonized patients (40% vs 0, p=0.011). All patients had prior exposure to acute care hospital (ACH), 37% to long-term acute care hospital, and 42% to skilled nursing facility within 1 year of diagnosis. Chronic wounds, prior broad-spectrum antibiotic use, and indwelling devices were prevalent in both groups; more than half required mechanical ventilation in the last month, and one third had tracheostomy at the time of C. auris detection. Almost 60% had a prior history of drug-resistant organisms, including multi-drug resistant gram negative (37%) and carbapenem-resistant (20%) organisms. Blood (82%) and wound (18%) were sources of invasive candidiasis. More than half (61%) of the testing was performed at ACH. Nine patients (82%) with invasive disease were treated with echinocandins (88%); among the colonized, two (4%) were treated with echinocandins but had persistent colonization. Thirty-day mortality was not significantly different among the two groups and was nearly 20%. Conclusions: In this large cohort study, a history of healthcare exposure, drug-resistant organisms, use of broad-spectrum antibiotics, indwelling devices, and chronic wounds were common risk factors among C. auris patients. Limiting the use of broad-spectrum antimicrobials and invasive devices, adherence to infection prevention and control practices, and interfacility transfer communication are important mitigating strategies to reduce the incidence and spread of C. auris.

First Detected Transmission of C. auris within a Minnesota Healthcare Facility Following Exposure in the Emergency Department

Background: Candida auris reporting and submission of confirmed or possible isolates has been mandatory in Minnesota since August 2019. On August 9, 2023, the Minnesota Department of Health (MDH) was notified of a C. auris isolate in hip tissue from a patient in acute care hospital A (ACH-A). Only 9 cases of C. auris were detected prior to August 2023, in Minnesota, and all from patients with a history of international healthcare or healthcare in endemic C. auris locations of the United States. Methods: The MDH Public Health Laboratory (MDH-PHL) confirmed identification of C. auris from the ACH-A isolate by MALDI-TOF. MDH partnered with ACH-A to review medical records, assess infection prevention and control (IPC) practices, conduct contact tracing, and identify patients for colonization screening. Screening was performed on all patients that overlapped with the index case (case A) and were admitted to a facility in the same healthcare system as ACH-A. Facilities accepting discharged patients who overlapped with case A were contacted for colonization screening. Overlapping patients, no longer admitted to a healthcare facility, were sent a notification letter, and offered outpatient screening. Composite axilla/groin swabs were screened for C. auris using real-time PCR at MDH-PHL, who also performed whole genome sequencing (WGS) and single nucleotide polymorphism (SNP) analysis. Results: Case A’s medical record showed only Minnesota healthcare exposures, a surgical procedure in June 2023 and indicated the case overlapped with a previous case (case B) from July 2023, who had recent international healthcare. The two cases were hospitalized at ACH-B July 12-18, on different care floors without evident links to shared services. However, the cases were in adjacent rooms in ACH-B Emergency Department (ED) on July 3 for 5 hours, when C. auris status of case B was unknown. WGS indicated both isolates were within clade I (South Asian) and separated by 2 SNPs, suggesting relatedness. Extensive colonization screening occurred among 109 potentially exposed patients, including 18 patients from the ED. No additional C. auris was detected. Conclusions: This case represents the first detected transmission of C. auris within a Minnesota healthcare facility. The role of C. auris transmission within the ED is not well understood. Medical record review in combination with WGS analysis suggests potential transmission within the ED. Clinicians should be aware of the risks for C. auris transmission in the ED and follow all IPC measures to prevent transmission of this emerging fungal pathogen.

Utilizing Technology to Fill the Ambulatory Care Communicable Disease Practice Gap

Background: Infection Prevention (IP) practices in ambulatory care are often reactive and many communicable diseases in the community often do not fall onto IP’s radar until the patient becomes ill enough to seek inpatient services. The gap between ambulatory and inpatient care can lead to increased transmission and illness severity. Early identification has substantial impacts on timely implementation of IP mitigation strategies, appropriate handoff upon entry into other care settings, and timely reporting to public health organizations. Current IP processes underutilize electronic health record (EHR) capabilities by relying upon lab driven notifications. This project sought to redesign the IP’s workflows, advancing the health system beyond the acute care setting and into the ambulatory care setting by adding the power of diagnosis codes to close a practice gap. Method: Infection Prevention and Information Technology collaborated to build silent best practice advisories (BPAs) in the EHR that utilized diagnosis codes related to Varicella zoster (VZV) infection charted by ambulatory care providers. These BPAs function by triggering infection statuses that populate the patient chart and include instructions to front line staff on personal protective equipment (PPE) requirements. These BPAs also trigger real-time notifications to the IP team to determine the validity of the infection status and exposure work-up necessity. Chart reviews of diagnosis codes utilized in pre and post intervention timeframes were completed to understand the impact of the silent BPAs. Percentages of patients captured, and Healthcare Worker (HCW) exposure reviews reported were evaluated to demonstrate effectiveness. Plan, Do, Study, Act (PDSA) was utilized to respond to gaps, increase efficiency, and limit erroneous infection statuses. Result: The one-year pre-intervention period revealed 36 total diagnosis codes used for Varicella zoster (VZV) infection; 3% of these infection cases were captured and 4% of eligible cases were reported for HCW exposure review. The one-year post intervention period revealed 40 total diagnosis codes used for VZV infection; 80% of these infection cases were captured and 70% of eligible cases were reported for HCW exposure review. PDSA quality improvement cycles allowed for refinement of the BPA logic that further increased infection cases captured to 100% with 100% of eligible cases reported for HCW exposure review. Conclusion: Utilizing the EHR, the organization appreciated enhanced identification of patients in real-time with VZV infection that allowed for appropriate mitigation strategies to be implemented. This proactive workflow design helps minimize the risk of transmission between ambulatory and acute settings and facilitated HCW exposure reviews.

Evidence-based nursing practice for the prevention of nasal and facial pressure injuries in patients with non-invasive positive pressure ventilation

To investigate the evidence-based practice of prevention and care of nasal and facial pressure injuries in patients with non-invasive positive pressure ventilation (NPPV) using the knowledge to action framework (KTA), and to explore its effectiveness. Using an evidence-based nursing approach, an evidence-based practice group was established to formulate a clinical problem, the literature from domestic and international databases were researched for relevant evidence, the evidence was introduced into clinical scenarios, an evidence-based practice plan was developed, and a strategy for applying the best evidence was constructed by conducting a baseline review of healthcare professionals and patients with NPPV, analyzing barriers and promoting factors, and making changes in clinical practice at the organizational level, the practitioner level, and the patient level. Purposive sampling method was used to select the healthcare staff of the cardiac surgical intensive care unit (CSICU) of the Shandong Provincial Hospital Affiliated to Shandong First Medical University, as well as the patients with NPPV admitted from October 1 to November 15, 2023 (pre-evidence-based practice) and November 16 to December 31 (post-evidence-based practice), as the subjects of the study. Through questionnaire analysis, the incidence of nasal and facial pressure injury of NPPV patients, the implementation rate of review indicators of medical staff, the score of the knowledge, belief and conduct of medical staff, and the compliance and comfort of patients before and after evidence-based practice were compared. A total of 52 medical staff were included, aged (28.54±6.50) years old, with 3.00 (1.00, 12.75) years of working experience; 2 doctoral degree holders (3.85%), 4 master degree holders (7.69%), 46 bachelor degree holders (88.46%); 2 with senior title (3.85%), 17 with intermediate title (32.69%), and 33 junior titles (63.46%). Fifty patient questionnaires were collected before and after evidence-based nursing practice; the differences between before and after evidence-based practice in terms of gender, age, body weight, duration of ventilator usage, 24-hour bleeding and total bleeding were not statistically significant and were comparable. Compared with the pre-evidence-based practice, after carrying out the corresponding evidence-based nursing practice, the incidence of nasal and facial pressure injuries of NPPV patients decreased from 16.00% (8/50) to 4.00% (2/50, P < 0.05), the total implementation rate of review indicators of medical staff increased from 79.73% to 94.08% (P < 0.01), and the total scores of knowledge, belief and conduct were significantly improved (141.96±13.88 vs. 114.65±19.72, P < 0.05), and compliance and comfort of patients were significantly improved (compliance score: 4.60±0.99 vs. 5.82±1.42, comfort score: 4.10±1.63 vs. 6.92±2.33, both P < 0.05). The application of an evidence-based nursing approach to obtain evidence related to the prevention of nasal and facial pressure injuries in patients with NPPV can be used to guide clinical practice, significantly reducing the incidence of nasal and facial pressure injuries in such patients, improving the implementation rate of review indicators and the knowledge, belief, and conduct scores of medical staff, and enhancing compliance and comfort of NPPV patients.

Hospital-Associated Transmission of Candida auris from Adult to Pediatric Patient

Background: Candida auris, an emerging multidrug-resistant fungus, is often difficult to control in hospital outbreaks. We report the hospital investigation and findings of a transmission of C. auris from patients hospitalized in an adult unit to a pediatric unit, the first in Maryland. Methods: Between June and September 2023, C. auris was recovered from two patients admitted to an adult Neuroscience Intensive Care Unit (ICU) and a patient admitted to a pediatric ICU. Infection control initiated an investigation involving staff interviews, observations and chart reviews. Cases were defined as any patient with clinical or surveillance cultures growing C. auris. Point prevalence surveillance was conducted by collecting nares and composite axilla/groin swabs from patients on the affected units. Environmental cultures collected using moistened E-Swabs (Copan, Murrieta, CA) from shared supplies were plated on CHROMagar Candida (BD, Sparks, MD). C. auris isolates from patients hospitalized at the facility between February 2022 and October 2023 were analyzed by WGS for relatedness. WGS was performed using Illumina NextSeq 300 bp paired-end sequencing (Illumina, San Diego, CA). Single nucleotide polymorphism (SNP) analysis was performed by comparing raw reads to the reference C. auris B8441 genome for subsequent clustering analysis (Ares Genetics, Vienna, Austria). Results: WGS demonstrated isolates from two adults and one pediatric patient were less than three SNPs different, suggesting a shared isolate. One additional pediatric case was identified from surveillance cultures collected from 27 patients. Investigation into possible transmission routes revealed healthcare personnel serving both units, specifically clinical teams and continuous electroencephalography (cEEG) technologists. Additionally, cEEG equipment was used on both adult and pediatric patients and twelve equipment surface swabs and three samples each of measuring tape and gel were collected. C. auris was not isolated, however sensitivity of environmental sampling is unclear and suspicion for possible fomite/environmental transmission persisted. Other possible transmission routes included gaps in hand hygiene, isolation, disinfection of shared equipment, and reuse of single-use items. Interventions included improving and monitoring infection prevention practices, educating multi-disciplinary personnel and heightened environmental cleaning. Conclusion: This case highlights the feasibility of transmission of C. auris between patients admitted to a geographically distant unit. Our investigation revealed multiple possible routes of transmission including direct contact (from healthcare personnel or equipment) or indirect environmental sources. Prevention of hospital-associated C. auris transmission likely necessitates meticulous adherence to hand hygiene, contact precautions, and careful cleaning and disinfection of patient environments and equipment used by all disciplines.Disclosure: Patricia Simner: Research Contracts: BD Diagnostics, OpGen Inc., Qiagen Sciences Inc, T2 Diagnostics, Accelerate Diagnostics; Research Collaborators:Ares Genetics, CosmosID, IDbyDNA, Illumina; Consulting: OpGen Inc., BD Diagnostics, Shionogi Inc., GeneCapture, Qiagen Sciences Inc, Entasis, Day Zero Diagnostics, Next Gen Diagnostics
