Integrated Genomic and Social Network Analyses of SARS-CoV-2 Transmission in the Healthcare Setting.

BACKGROUND: Infection prevention (IP) measures are designed to mitigate the transmission of pathogens in healthcare. Using large-scale viral genomic and social network analyses, we determined if IP measures used during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic were adequate in protecting healthcare workers (HCWs) and patients from acquiring SARS-CoV-2. METHODS: We performed retrospective cross-sectional analyses of viral genomics from all available SARS-CoV-2 viral samples collected at UC San Diego Health and social network analysis using the electronic medical record to derive temporospatial overlap of infections among related viromes and supplemented with contact tracing data. The outcome measure was any instance of healthcare transmission, defined as cases with closely related viral genomes and epidemiological connection within the healthcare setting during the infection window. Between November 2020 through January 2022, 12 933 viral genomes were obtained from 35 666 patients and HCWs. RESULTS: Among 5112 SARS-CoV-2 viral samples sequenced from the second and third waves of SARS-CoV-2 (pre-Omicron), 291 pairs were derived from persons with a plausible healthcare overlap. Of these, 34 pairs (12%) were phylogenetically linked: 19 attributable to household and 14 to healthcare transmission. During the Omicron wave, 2106 contact pairs among 7821 sequences resulted in 120 (6%) related pairs among 32 clusters, of which 10 were consistent with healthcare transmission. Transmission was more likely to occur in shared spaces in the older hospital compared with the newer hospital (2.54 vs 0.63 transmission events per 1000 admissions, P < .001). CONCLUSIONS: IP strategies were effective at identifying and preventing healthcare SARS-CoV-2 transmission.

Compliance of healthcare workers in a psychiatric inpatient ward to infection control practices during the COVID-19 pandemic: a participant observation study supplemented with a self-reported survey.

BACKGROUND: As an emerging infectious disease with a heterogenous and uncertain transmission pattern, coronavirus disease 2019 (COVID-19) has created a catastrophe in healthcare-associated infections (HAIs) and posed a significant challenge to infection control practices (ICPs) in healthcare settings. While the unique characteristics of psychiatric patients and clinical settings may make the implementation of ICPs difficult, evidence is lacking for compliance with ICPs among healthcare workers (HCWs) in a psychiatric setting during the COVID-19 pandemic. METHODS: A cross-sectional multi-method study based on participant unobtrusive observation coupled with the completion of a self-administered ICP survey was conducted to assess compliance with ICPs among HCWs in a psychiatric inpatient ward in a regional hospital. An online checklist, called eRub, was used to record the performance of HCWs in hand hygiene (HH) and other essential ICPs. Furthermore, a well-validated questionnaire (i.e., Compliance with Standard Precautions Scale, CSPS) was used to collect the participants' self-reported ICP compliance for later comparison. RESULTS: A total of 2,670 ICP opportunities were observed from January to April 2020. The overall compliance rate was 42.6%. HCWs exhibited satisfactory compliance to the wearing of mask (91.2%) and the handling of clinical waste (87.5%); suboptimal compliance to the handling of sharp objects (67.7%) and linen (72.7%); and poor compliance to HH (3.3%), use of gloves (40.9%), use of personal protective equipment (20%), and disinfection of used surface/area (0.4%). The compliance rates of the nurses and support staff to HH were significantly different (χ2 = 123.25, p < 0.001). In the self-reported survey, the overall compliance rate for ICPs was 64.6%. CONCLUSION: The compliance of HCWs in a psychiatric inpatient ward to ICPs during the COVID-19 pandemic ranged from poor to suboptimal. This result was alarming. Revisions of current ICP guidelines and policies that specifically target barriers in psychiatric settings will be necessary.

Barriers and facilitators to early mobilisation and weight-bearing as tolerated after hip fracture surgery among older adults in Saudi Arabia: a qualitative study.

OBJECTIVE: To explore the practice of prescribing and implementing early mobilisation and weight-bearing as tolerated after hip fracture surgery in older adults and identify barriers and facilitators to their implementation. METHODS: Semi-structured interviews were conducted with 20 healthcare providers (10 orthopaedic surgeons and 10 physiotherapists) from Saudi Arabian government hospitals. Data were analysed using inductive thematic analysis. RESULTS: While early mobilisation and weight-bearing as tolerated were viewed as important by most participants, they highlighted barriers to the implementation of these practices. Most participants advocated for mobility within 48 h of surgery, aligning with international guidance; however, the implementation of weight-bearing as tolerated was varied. Some participants stressed the type of surgery undertaken as a key factor in weight-bearing prescription. For others, local protocols or clinician preference was seen as most important, the latter partially influenced by where they were trained. Interdisciplinary collaboration between orthopaedic surgeons and physiotherapists was seen as a crucial part of postoperative care and weight-bearing. Patient and family member buy-in was also noted as a key factor, as fear of further injury can impact a patient's adherence to weight-bearing prescriptions. Participants noted a lack of standardised postoperative protocols and the need for routine patient audits to better understand current practices and outcomes. CONCLUSION: This study contributes to national and global discussions on the prescription of early mobilisation and weight-bearing as tolerated. It highlights the necessity for a harmonised approach, incorporating standardised, evidence-based protocols with patient-specific care, robust healthcare governance and routine audits and monitoring for quality assurance and better patient outcomes.

Precautions for seafood consumers: An updated review of toxicity, bioaccumulation, and rapid detection methods of marine biotoxins.

Seafood products are globally consumed, and there is an increasing demand for the quality and safety of these products among consumers. Some seafoods are easily contaminated by marine biotoxins in natural environments or cultured farming processes. When humans ingest different toxins accumulated in seafood, they may exhibit different poisoning symptoms. According to the investigations, marine toxins produced by harmful algal blooms and various other marine organisms mainly accumulate in the body organs such as liver and digestive tract of seafood animals. Several regions around the world have reported incidents of seafood poisoning by biotoxins, posing a threat to human health. Thus, most countries have legislated to specify the permissible levels of these biotoxins in seafood. Therefore, it is necessary for seafood producers and suppliers to conduct necessary testing of toxins in seafood before and after harvesting to prohibit excessive toxins containing seafood from entering the market, which therefore can reduce the occurrence of seafood poisoning incidents. In recent years, some technologies which can quickly, conveniently, and sensitively detect biological toxins in seafood, have been developed and validated, these technologies have the potential to help seafood producers, suppliers and regulatory authorities. This article reviews the seafood toxins sources and types, mechanism of action and bioaccumulation of marine toxins, as well as legislation and rapid detection technologies for biotoxins in seafood for official and fishermen supervision.

Use of proxy indicators for automated surveillance of severe acute respiratory infection, the Netherlands, 2017 to 2023: a proof-of-concept study.

BackgroundEffective pandemic preparedness requires robust severe acute respiratory infection (SARI) surveillance. However, identifying SARI patients based on symptoms is time-consuming. Using the number of reverse transcription (RT)-PCR tests or contact and droplet precaution labels as a proxy for SARI could accurately reflect the epidemiology of patients presenting with SARI.AimWe aimed to compare the number of RT-PCR tests, contact and droplet precaution labels and SARI-related International Classification of Disease (ICD)-10 codes and evaluate their use as surveillance indicators.MethodsPatients from all age groups hospitalised at Leiden University Medical Center between 1 January 2017 up to and including 30 April 2023 were eligible for inclusion. We used a clinical data collection tool to extract data from electronic medical records. For each surveillance indicator, we plotted the absolute count for each week, the incidence proportion per week and the correlation between the three surveillance indicators.ResultsWe included 117,404 hospital admissions. The three surveillance indicators generally followed a similar pattern before and during the COVID-19 pandemic. The correlation was highest between contact and droplet precaution labels and ICD-10 diagnostic codes (Pearson correlation coefficient: 0.84). There was a strong increase in the number of RT-PCR tests after the start of the COVID-19 pandemic.DiscussionAll three surveillance indicators have advantages and disadvantages. ICD-10 diagnostic codes are suitable but are subject to reporting delays. Contact and droplet precaution labels are a feasible option for automated SARI surveillance, since these reflect trends in SARI incidence and may be available real-time.

Nurses' safety climate, quality of care, and standard precautions adherence and compliance: A cross-sectional study.

INTRODUCTION: Investigations about the interrelationships of nurses' safety climate, quality of care, and standard precautions (SP) adherence and compliance remain particularly scarce in the literature. Thus, we tested a model of the associations between nurses' safety climate, quality of care, and the factors influencing adherence and compliance with SPs utilizing the structural equation modeling (SEM) approach. DESIGN: Cross-sectional design complying with STROBE guidelines. METHODS: Using convenience sampling, nurses (n = 730) from the Philippines were recruited. Data were collected between April and September 2022 using four validated self-report measures. Spearman Rho, mediation and path analyses, and SEM were employed for data analysis. RESULTS: Acceptable model fit indices were shown by the emerging model. The safety climate is positively associated with quality of care and factors influencing adherence to and compliance with SPs. Quality of care directly affected factors influencing adherence to SPs. The factors influencing adherence to SPs directly affected SP compliance. Quality of care mediated between safety climate and the factors influencing adherence to SPs. Factors influencing adherence to SPs mediated between safety climate, quality of care, and SP compliance. CONCLUSIONS: The study's variables are not distinct but overlapping nursing concepts that must be examined collectively. Nurse administrators can utilize the emerging model to formulate strategies and regulations for evaluating and enhancing nurses' safety climate, quality of care, and SP adherence and compliance. CLINICAL RELEVANCE: Our findings may impact policymaking, organizational, and individual levels to improve nurses' clinical practice. PATIENT OR PUBLIC CONTRIBUTION: This study had no patient contribution or public funding.

Research on the relationship between nurses' compliance with standard precautions, servant leadership and emotional exhaustion: A cross-sectional survey.

AIM: This study aimed to analyse the effects of servant leadership on nurses' emotional failure and compliance with standard precautions and to explore the moderating effect of individual resilience. DESIGN: A cross-sectional survey. METHODS: This descriptive cross-sectional study was conducted from October 9 to November 1, 2022. The convenience sampling method was used to collect questionnaire data from 924 clinical nurses in a third-class general hospital in Chongqing, China. RESULTS: The emotional exhaustion and compliance with standard precautions were at the general level. Servant leadership mediated by emotional exhaustion had a significant positive predictive effect on compliance with standard precautions. Personal resilience played a negative moderating role in the relationship between servant leadership and emotional exhaustion. For nurses with low resilience, servant leadership had a greater impact on emotional exhaustion. CONCLUSION: The current compliance with standard precautions for clinical nurses is not high due to emotional exhaustion. The level of servant leadership can alleviate nurses' emotional exhaustion and improve compliance with standard precautions. Especially for nurses with low personal resilience, the care and support of department leaders are needed. IMPACT: We found that the compliance with standard precautions is not high, and the link between emotional exhaustion, servant leadership and compliance with standard precautions provides a basis for further patient care. NO PATIENT OR PUBLIC CONTRIBUTION: There was no patient or public involvement. IMPACT STATEMENT: Nurses are the key population for hospital infection prevention and control, and their level of compliance with standard precautions is of great significance for hospital infection prevention and control. However, in practice, nurses' compliance with standard precautions is generally low. Most of the previous studies on nurses' compliance with standard precautions were conducted from the perspective of individual nurses, based on the staff's 'knowledge, belief, and action' to study the current status of compliance with standard precautions and the factors affecting adherence, with less attention paid to the influence of psychological, environmental, and organizational factors. Therefore, the study focuses on the impact of servant leadership and emotional exhaustion on standard precautionary adherence, which is of great significance for good care management at the organizational level. It also explored how the impact of servant leadership on emotional exhaustion varies across levels of resilience, which is important for accurately identifying different types of nursing staff and targeting assistance.

Patients in isolation, their physical, environmental and mental health: An exploratory study.

BACKGROUND: Strict patient isolation in hospital is associated with adverse health outcomes. However, there is a lack of high-quality evidence for effective interventions to improve safety and quality of care for these patients. AIMS: To identify patient reported areas for improvement in the care of patients in hospital isolation and to determine the feasibility of collecting patient reported outcomes using validated tools. METHODS: Design An exploratory mixed methods study. Setting A major metropolitan teaching hospital in Melbourne, Australia. Participants Patients in hospital isolation for transmissible infections. Data collection Data were collected by (1) phone interviews with patients in isolation and (2) seven validated measurement tools to assess cognition, loneliness, nutritional status, quality of life, anxiety and depression and physical activity. Data were collected between September and December 2021. Data analysis Interviews were transcribed and analysed using thematic analysis. Quantitative data were analysed descriptively including participant characteristics and outcome data. RESULTS: Participants identified areas for improvement including activities to decrease boredom, more contact with staff to mitigate loneliness and increase comfort care, and formalised communication about clinical treatment and discharge plan. Patients with gastrointestinal symptoms were happier to be alone. There were operational challenges within the health service including delays and miscommunication. Only 70% of the participants completed all questionnaires. CONCLUSION: This study identified areas for improvement in care of patients in isolation and demonstrated that collecting patient reported outcomes using validated tools was feasible. The results of this research will inform development of an intervention to manage adverse effects. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Patients in hospital isolation require additional consideration to ensure that their needs are met to avoid adverse outcomes. The patient experience and comfort can be negatively affected when fundamental care is lacking. REPORTING METHOD (EQUATOR): EQUATOR guidelines for Mixed Methods Reporting in Rehabilitation & Health Sciences (MMR-RHS). PATIENT OR PUBLIC CONTRIBUTION: Thirteen patients in hospital isolation agreed to participate in this study, sharing their experiences through interviews and assessment.

Nurses' compliance to standard precautions prior to and during COVID-19.

AIMS: To measure nurses' compliance with standard precautions during the COVID-19 pandemic, compare findings with previous assessments and describe the barriers affecting nurses' compliance. BACKGROUND: Healthcare providers' compliance with standard precautions is still limited worldwide. Implementation of infection control policies in hospitals is needed internationally, especially during a pandemic. Surprisingly, studies exploring nurses' compliance with standard precautions are lacking during COVID-19. METHODS: A multicenter cross-sectional study was adopted in two Italian hospitals. Nurses' compliance with standard precautions was measured through The Compliance with Standard Precautions Scale (Italian version). An open-ended question explored the barriers to nurses' compliance with standard precautions. Reporting, followed the STROBE guidelines. RESULTS: A total of 201 nurses were enrolled in 2020. Nurses' compliance with standard precautions was suboptimal. A statistically significant improvement in the compliance rate with standard precautions was observed between pre- and during COVID-19 assessments. High compliance was found in the appropriate use of surgical masks, gloves and sharps disposal. Nurses perceived personal, structural and organizational barriers to standard precautions adherence. CONCLUSION: Nurses' compliance with standard precautions was not 100%, and different factors impeded nurses to work safely. Our findings provide institutional leaders and educators with the basis for implementing policies to optimize nurse safety, well-being and patient care. IMPLICATIONS FOR NURSING AND HEALTH POLICIES: Nurses have the right to work safely, and when the shortage of personal protective equipment and nurses during an emergency threatens healthcare quality worldwide, policymakers are challenged to act by establishing an effective allocation of resources for consistent compliance with standard precautions. Moreover, nurses should actively engage in the implementation of infection control policies to improve safe behaviours among citizens and students accessing hospitals.

RETRACTED: Safety climate, quality of care, adherence to and compliance with standard precautions among nurses: Structural equation modeling.

AIMS: The aim was to investigate the interrelationships of nurses' safety climate, quality of care, and adherence to and compliance with standard precautions (SPs). BACKGROUND: Investigations about nurses' safety climate and quality care and their association with adherence to and compliance with SPs remain remarkably scant across literature, specifically among developing countries like the Philippines. DESIGN: Cross-sectional design and structural equation modeling (SEM) approach while complying with STROBE guidelines. METHODS: Participant nurses were recruited using convenience sampling (n = 870). Four validated self-report instruments were used to collect data from February to August 2022. Spearman rho, SEM, mediation, and path analyses were employed for data analysis. RESULTS: The emerging model showed acceptable model fit parameters. The safety climate positively influenced the quality of care and adherence to and compliance with SPs. Quality of care directly affected adherence to SPs, while adherence to SPs directly affected compliance with SPs. The quality of care mediated the relationship between safety climate and adherence to SPs. Whereas adherence to SPs mediated the relationships between safety climate and compliance with SPs and the quality of care and compliance with SPs. CONCLUSIONS: Nurses' safety climate directly affected the quality of care and SPs adherence and compliance. The quality of care mediated the impact of safety climate on SPs adherence. Finally, SPs adherence demonstrated a mediating effect among quality of care, safety climate, and SPs compliance. IMPLICATIONS FOR NURSING POLICY AND PRACTICE: Nursing policymakers and administrators can use the findings to design strategic policies and sustainable in-service educational courses fostering and maintaining nurses' safety climate, quality of care, and SPs adherence and compliance.

The Impact of Universal Glove and Gown Use on Clostridioides Difficile Acquisition: A Cluster-Randomized Trial.

BACKGROUND: Clostridioides difficile is the most common cause of healthcare-associated infections in the United States. It is unknown whether universal gown and glove use in intensive care units (ICUs) decreases acquisition of C. difficile. METHODS: This was a secondary analysis of a cluster-randomized trial in 20 medical and surgical ICUs in 20 US hospitals from 4 January 2012 to 4 October 2012. After a baseline period, ICUs were randomized to standard practice for glove and gown use versus the intervention of all healthcare workers being required to wear gloves and gowns for all patient contact and when entering any patient room (contact precautions). The primary outcome was acquisition of toxigenic C. difficile determined by surveillance cultures collected on admission and discharge from the ICU. RESULTS: A total of 21 845 patients had both admission and discharge perianal swabs cultured for toxigenic C. difficile. On admission, 9.43% (2060/21 845) of patients were colonized with toxigenic C. difficile. No significant difference was observed in the rate of toxigenic C. difficile acquisition with universal gown and glove use. Differences in acquisition rates in the study period compared with the baseline period in control ICUs were 1.49 per 100 patient-days versus 1.68 per 100 patient-days in universal gown and glove ICUs (rate difference, -0.28; generalized linear mixed model, P = .091). CONCLUSIONS: Glove and gown use for all patient contact in medical and surgical ICUs did not result in a reduction in the acquisition of C. difficile compared with usual care. CLINICAL TRIALS REGISTRATION: NCT01318213.

Are contact precautions "essential" for the prevention of healthcare-associated methicillin-resistant Staphylococcus aureus?

The recently updated SHEA/IDSA/APIC practice recommendations for MRSA prevention in acute care facilities list contact precautions (CP) for patients known to be infected or colonized with MRSA as an "essential practice", meaning that it should be adopted in all acute care facilities. We argue that existing evidence on benefits and harms associated with CP do not justify this recommendation. There are no controlled trials that support broad use of CP for MRSA prevention. Data from hospitals that have discontinued CP for MRSA have found no impact on MRSA acquisition or infection. The burden and harms of CP remain concerning, including the environmental impact of increased gown and glove use. We suggest that CP be included among other "additional approaches" to MRSA prevention that can be implemented under specific circumstances (e.g. outbreaks, evidence of ongoing transmission despite application of essential practices).

Active Surveillance and Contact Precautions for Preventing Methicillin-Resistant Staphylococcus aureus Healthcare-Associated Infections During the COVID-19 Pandemic.

BACKGROUND: Statistically significant decreases in methicillin-resistant Staphylococcus aureus (MRSA) healthcare-associated infections (HAIs) occurred in Veterans Affairs (VA) hospitals from 2007 to 2019 using a national policy of active surveillance (AS) for facility admissions and contact precautions for MRSA colonized (CPC) or infected (CPI) patients, but the impact of suspending these measures to free up laboratory resources for testing and conserve personal protective equipment for coronavirus disease 2019 (COVID-19) on MRSA HAI rates is not known. METHODS: From July 2020 to June 2022 all 123 acute care VA hospitals nationwide were given the rolling option to suspend (or re-initiate) any combination of AS, CPC, or CPI each month, and MRSA HAIs in intensive care units (ICUs) and non-ICUs were tracked. RESULTS: There were 917 591 admissions, 5 225 174 patient-days, and 568 MRSA HAIs. The MRSA HAI rate/1000 patient-days in ICUs was 0.20 (95% confidence interval [CI], .15-.26) for facilities practicing "AS + CPC + CPI" compared to 0.65 (95% CI, .41-.98; P < .001) for those not practicing any of these strategies, and in non-ICUs was 0.07 (95% CI, .05-.08) and 0.12 (95% CI, .08-.19; P = .01) for the respective policies. Accounting for monthly COVID-19 facility admissions using a negative binomial regression model did not change the relationships between facility policy and MRSA HAI rates. There was no significant difference in monthly facility urinary catheter-associated infection rates, a non-equivalent dependent variable, in the policy categories in either ICUs or non-ICUs. CONCLUSIONS: Facility removal of MRSA prevention practices was associated with higher rates of MRSA HAIs in ICUs and non-ICUs.

Living with HIV during COVID-19: knowledge and worry about COVID-19, adherence to COVID-19-related precautions, and HIV health outcomes.

The COVID-19 pandemic has been profound impacts on mental and physical health of individuals with chronic diseases. Thus, it is important to understand the effects of the COVID-19 pandemic on people living with HIV. We aimed to assess the association between COVID-19-related knowledge and worry, HIV-related health practices and outcomes, and adherence to precautions related to COVID-19, and possible associations of these factors with HIV treatment outcomes (ART adherence and viral load). A cross-sectional survey was conducted between October 2020 and February 2021 among 291 PLWH at two large university hospital HIV clinics in Izmir, Turkey. Additionally, the most recent HIV-RNA load, CD4 count was recorded using medical records. Logistic regression analyses were performed to determine predictors of self-reported adherence to COVID-19-related precautions, ART adherence and undetectable viral load. COVID-19-related worry, COVID-19-related knowledge, and ART adherence were significant predictors of adherence to COVID-19-related precautions. Furthermore, adherence to COVID-19-related precautions was a significant predictor of both ART adherence and undetectable viral load. Findings provide a unique aspect of the interrelations of COVID and living with HIV. Since health behaviors and outcomes for COVID-19 and HIV seem to be interrelated, treatment practices and interventions that address these simultaneously may enhance their efficacy.

Transvenous Lead Extraction in Pediatric Patients　- Is It the Same Procedure in Children as in Adults?

BACKGROUND: Cardiac implantable electronic devices (CIED) are very rare in the pediatric population. In children with CIED, transvenous lead extraction (TLE) is often necessary. The course and effects of TLE in children are different than in adults. Thus, this study determined the differences and specific characteristics of TLE in children vs. adults.Methods and Results: A post hoc analysis of TLE data in 63 children (age ≤18 years) and 2,659 adults (age ≥40 years) was performed. The 2 groups were compared with respect to risk factors, procedure complexity, and effectiveness. In children, the predominant pacing mode was a single chamber ventricular system and lead dysfunction was the main indication for lead extraction. The mean implant duration before TLE was longer in children (P=0.03), but the dwell time of the oldest extracted lead did not differ significantly between adults and children. The duration (P=0.006) and mean extraction time per lead (P<0.001) were longer in children, with more technical difficulties during TLE in the pediatric group (P<0.001). Major complications were more common, albeit not significantly, in children. Complete radiographic and procedural success were significantly lower in children (P<0.001). CONCLUSIONS: TLE in children is frequently more complex, time consuming, and arduous, and procedural success is more often lower. This is related to the formation of strong fibrous tissue surrounding the leads in pediatric patients.

Aerosol precautions and airway complications: a national prospective multicentre cohort study.

The perceived risk of transmission of aerosolised viral particles from patients to airway practitioners during the COVID-19 pandemic led to the widespread use of aerosol precautions, including personal protective equipment and modifications to anaesthetic technique. The risk of these aerosol precautions on peri-operative airway complications has not been assessed outside of simulation studies. This prospective, national, multicentre cohort study aimed to quantify this risk. Adult patients undergoing general anaesthesia for elective or emergency procedures over a 96-hour period were included. Data collected included use of aerosol precautions by the airway practitioner, airway complications and potential confounding variables. Mixed-effects logistic regression was used to assess the risk of individual aerosol precautions on overall and specific airway complications. Data from 5905 patients from 70 hospital sites were included. The rate of airway complications was 10.0% (95%CI 9.2-10.8%). Use of filtering facepiece class 2 or class 3 respirators was associated with an increased risk of airway complications (odds ratio 1.38, 95%CI 1.04-1.83), predominantly due to an association with difficult facemask ventilation (odds ratio 1.68, 95%CI 1.09-2.61) and desaturation on pulse oximetry (odds ratio 2.39, 95%CI 1.26-4.54). Use of goggles, powered air-purifying respirators, long-sleeved gowns, double gloves and videolaryngoscopy were not associated with any alteration in the risk of airway complications. Overall, the use of filtering facepiece class 2 or class 3 respirators was associated with an increased risk of airway complications, but most aerosol precautions used during the COVID-19 pandemic were not.

Infectious Risk of Arterial Lines: A Narrative Review.

Arterial catheter-related bloodstream infections have been identified as a significant healthcare burden. However, the incidence of arterial catheter-related infections is commonly underestimated in clinical practice, and adherence to CDC-recommended practices is inconsistent. Several categories of interventions have been studied to prevent arterial catheter-related bloodstream infections, which include barrier precautions, cutaneous antisepsis, insertion site selection, dressings, chlorhexidine-impregnated sponges, and the duration of catheter placement with or without catheter replacement. The majority of these studies are limited by small sample sizes and single-center designs, and further randomized trials are needed to update current clinical practice guidelines to reduce the risk of arterial catheter-related infections.

Revisiting the personal protective equipment components of transmission-based precautions for the prevention of COVID-19 and other respiratory virus infections in healthcare.

The COVID-19 pandemic highlighted some potential limitations of transmission-based precautions. The distinction between transmission through large droplets vs aerosols, which have been fundamental concepts guiding infection control measures, has been questioned, leading to considerable variation in expert recommendations on transmission-based precautions for COVID-19. Furthermore, the application of elements of contact precautions, such as the use of gloves and gowns, is based on low-quality and inconclusive evidence and may have unintended consequences, such as increased incidence of healthcare-associated infections and spread of multidrug-resistant organisms. These observations indicate a need for high-quality studies to address the knowledge gaps and a need to revisit the theoretical background regarding various modes of transmission and the definitions of terms related to transmission. Further, we should examine the implications these definitions have on the following components of transmission-based precautions: (i) respiratory protection, (ii) use of gloves and gowns for the prevention of respiratory virus infections, (iii) aerosol-generating procedures and (iv) universal masking in healthcare settings as a control measure especially during seasonal epidemics. Such a review would ensure that transmission-based precautions are consistent and rationally based on available evidence, which would facilitate decision-making, guidance development and training, as well as their application in practice.

Effectiveness of implementing of an infection control link nurse program to improve compliance with standard precautions and hand hygiene among nurses: a quasi-experimental study.

BACKGROUND: Standard precautions (SPs) including hand hygiene are considered fundamental protective measures to manage health care-associated infections (HCAIs) and to reduce occupational health hazards. The purpose of this research was to examine the effectiveness of an infection control link nurse (ICLN) program on compliance with SPs and hand hygiene among nurses. METHODS: A quasi-experimental study with a pretest-post-test design was conducted with participating of 154 clinical nurses who worked in different wards of a tertiary referral teaching hospital in Iran. The intervention group (n = 77) had 16 infection control link nurses nominated. The control group (n = 77) received only the standard multimodal approach used in the hospital. Pre- and post-test assessment of compliance with standard precautions and hand hygiene compliance was performed via the Compliance with Standard Precautions Scale (CSPS) and the World Health Organization observational hand hygiene form. Two independent sample t-tests were used to examine differences between Compliance with Standard Precautions and hand hygiene Compliance among nurses in intervention and control group. Multiple linear regression analysis was used to assess the effect size. RESULTS: After developing and implementing the infection control link nurse program, no statistically significant improvement was found in the Compliance with Standard Precautions (ß = 5.18; 95% CI= -0.3-10.65, p = 0.064). An improvement in hand hygiene compliance was observed among nurses in the intervention group that improved statistically significant from 18.80% before the program to 37.32% 6 months after the program (ß = 20.82; 95% CI 16.40-25.25, p < 0.001). CONCLUSIONS: Given the continuing level of interest that exists in improving health care workers' hand hygiene practices, the findings of this study provide significant practical implications for hospitals seeking to improve compliance with hand hygiene among nurses, showing the effectiveness of using infection control link nurse program. Further research is needed to assess effectiveness of using infection control link nurse program to improve compliance with standard precautions.

Posterior Approach Total Hip Arthroplasty Utilizing a Monoblock Dual-Mobility Construct Without Posterior Hip Precautions: A Series of 580 Hips With One Dislocation.

BACKGROUND: Instability remains a devastating complication following total hip arthroplasty. Here we describe a mini-posterior approach with a monoblock dual-mobility implant without "traditional posterior hip precautions" yielding excellent results. METHODS: There were 580 consecutive hips in 575 patients who underwent total hip arthroplasty utilizing a monoblock dual-mobility implant and a mini-posterior approach. With this technique, the acetabular component positioning does not rely on tradition intra-operative radiographic abduction and anteversion goals but rather uses patient-specific anatomic landmarks (anterior acetabular rim and, when visible, the transverse acetabular ligament) to set cup position; stability is assessed with a significant, dynamic intra-operative test of range of motion. Patients' mean age was 64 years (range, 21 to 94), and 53.7% were women. RESULTS: Mean abduction was 48.4° (range, 29° to 68°) and mean anteversion was 24.7° (range, -1° to 51°). Patient Reported Outcomes Measurement Information System scores improved in every measured domain from preoperative to final postoperative visit. There were seven (1.2%) patients who required reoperation, with mean time to reoperation of 1.3 months (range, one to 176 days). Only one patient (0.2%) who had a preoperative history of spinal cord injury and Charcot arthropathy dislocated. CONCLUSION: A posterior approach hip surgeon may want to consider using a monoblock dual-mobility construct and avoidance of traditional posterior hip precautions to achieve early hip stability with an extremely low dislocation rate and high patient satisfaction scores.
