Cost Analysis of a Hand Hygiene Improvement Strategy in Long-Term Care Facilities.

OBJECTIVES: To evaluate whether the costs of a successful tailored multifaceted strategy to improve hand hygiene compliance outweighed the savings by reducing infection costs in Dutch long-term care facilities (LTCFs). DESIGN: A retrospective cost analysis alongside a stepped-wedge cluster-randomized controlled trial. SETTING AND PARTICIPANTS: The study included 14 LTCFs (23 wards) in the Netherlands. METHODS: The cost analysis was based on the costs of the intervention vs the savings from avoided infections and associated treatment costs. Infection-related costs of the "usual-care" period were compared with the combined infection-related costs and intervention costs from the "intervention" period and the costs in the "post-intervention period." Multilevel analyses, with a linear model with periods as fixed effects, random effects for cluster LTCFs, and fixed effects for each step, were completed. RESULTS: There are no significant differences in total costs considering the 3 periods. When adjusting for time and clustering, the mean infection-related costs per week per LTCF for all the infections combined were highest during "usual-care" before the hand hygiene intervention was performed, namely 680 euros per week. Assuming the effect of the improvement strategy would be present for 12 months, the costs per week in the "intervention" and "post-intervention" periods were 627 euros (95% CI, 383-871) and 731 euros (95% CI, 508-954), respectively. Assuming the effect of the improvement strategy will last longer than 1 year (ie, 18 and 24 months), the average cost for the "intervention period" and the "post-intervention" period decreased to 615 euros and 719 euros during the intervention and 609 euros and 715 euros after the intervention, respectively. CONCLUSIONS AND IMPLICATIONS: Our multifaceted hand hygiene improvement strategy achieves cost savings. The results of our study are the first of an economic analysis of a hand hygiene improvement strategy in LTCFs. The results need to be confirmed by further economic evaluations.

Cell Phones in the OR: A Cross-Sectional Study of Norwegian Perioperative Nurses' Knowledge, Practice, and Attitudes.

Few studies have focused on the use of cell phones in the OR. In Norway, researchers sought to assess perioperative nurses' knowledge, practice, and attitudes associated with cell phone use in the OR and distributed a nationwide questionnaire via a social media platform. More than 80% of the 332 respondents thought that cell phones were contaminated and that pathogens could contaminate hands. Almost all respondents brought their phone to work; approximately 61% of respondents carried it in their pocket in the OR. Responses to questions about phone cleaning showed that 39 (11.7%) of the respondents routinely cleaned their phone before entering the OR and 33 (9.9%) of the respondents cleaned it when leaving the OR. Less than 20% of respondents indicated their facility had guidelines for cleaning personal cell phones. Opportunities for improvement in cell phone cleaning in ORs exist and additional research involving all perioperative team members is needed.

Understanding the significance of microbiota recovered from health care surfaces.

BACKGROUND: Microbial contamination of hospital surfaces remains despite adherence to routine disinfection. Our study demonstrates bioburden from various types of hospital high-touch surfaces and the pathogenicity of all bacteria recovered. METHODS: Several high-touch hospital surfaces from a single medical-surgical unit were sampled and cultured using replicate organism detection and counting (RODAC) Tryptic Soy agar plates. Colonies were then subcultured to blood agar plates and speciated using MALDI-TOF. The local microbiology laboratory database was queried for any clinical isolate match with the environmental samples recovered. RESULTS: Manikins, bed rails, and workstations-on-wheels were the most contaminated surfaces with the largest variety of bacteria isolated from manikins and bed rails. A total of 60 different types of pathogens were isolated, 18 of which were well-known pathogens, and 7 were classified as important in the health care setting by CDC. Our clinical microbiology laboratory identified 29 of 60 hospital surface bacteria in clinical isolates. Urine, soft tissue, and blood were the most common sources of clinical isolates. CONCLUSIONS: Surfaces in the health care environment harbor both well-known and not-so-well-known human pathogens. Several not-so-well-known pathogens are skin flora or environmental bacteria, which in the right setting, can become pathogenic and cause diseases including meningitis, brain abscess, endocarditis, and bacteremia.

A Review of the Evidence on the Role of Floors and Shoes in the Dissemination of Pathogens in a Healthcare Setting.

Background: It is generally accepted that shoes and floors are contaminated with pathogens including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and Clostridium difficile, yet correlation to clinical infection is not well established. Because floors and shoes are low-touch surfaces, these are considered non-critical surfaces for cleaning and disinfection. The purpose of this review is to assess peer-reviewed literature inclusive of floors and shoe soles as contributors to the dissemination of infectious pathogens within healthcare settings. Methods: Using the Preferred Reporting Items for Systematic Reviews (PRISMA) methodology, PubMed and Medline were searched for articles assessing the presence of pathogens on or the transmission of pathogens between or from floors or shoe soles/shoe covers. Inclusion criteria are the human population within healthcare or controlled experimental settings after 1999 and available in English. Results: Four hundred eighteen articles were screened, and 18 articles documented recovery of bacterial and viral pathogens from both floors and shoes. Seventy-two percent (13/18) of these were published after 2015, showing increased consideration of the transfer of pathogens to high-touch surfaces from shoe soles or floors during patient care. Conclusions: There is evidence that floors and shoes in healthcare settings are contaminated with several different species of health-care-associated pathogens including MRSA, VRE, and Clostridium difficile.

Personal stethoscope disinfection practices and bacterial contamination: A cross-sectional study at the University Hospital Emergency Department in Belgrade, Serbia.

BACKGROUND: A significant reduction in bacterial growth on stethoscope membranes has been noticed after performing daily disinfection. Nevertheless, disinfection is rarely performed. We aimed to assess self-reported stethoscope disinfection practices among medical doctors, detect bacterial contamination on personal stethoscopes, and estimate the effectiveness of 70% ethanol as a stethoscope disinfecting agent. METHODS: To determine stethoscope disinfection practices, participants filled out a questionnaire (N = 47), followed by providing stethoscopes for bacterial analysis. Differences in bacterial contamination were observed through the self-reported frequency and method of stethoscope disinfection. The effect of disinfecting with 70% ethanol was evaluated by comparing the presence of bacterial growth before and after disinfection. RESULTS: The presence of bacterial growth was found in 78.7% of the stethoscope samples, with the median (interquartile range) number of colony-forming units at 25 (10-105). The frequency of disinfection greatly impacted the number of colony-forming units, and the method affected the presence of bacterial growth. Disinfection of stethoscope membranes using 70% ethanol resulted in a compelling 97.3% reduction of bacterial growth. CONCLUSIONS: Adequate stethoscope disinfection is highly efficient in reducing bacterial contamination and as such should be considered a critical step in hygienic practices.

Health care-associated Clostridioides difficile infection: Learning the perspectives of health care workers to build successful strategies.

BACKGROUND: Clostridioides difficile (C difficile) is one of the most common health care-associated infections that negatively impact patient care and health care costs. This study takes a unique approach to C difficile infection (CDI) control by investigating key prevention obstacles through the perspectives of Stanford health care (SHC) frontline health care personnel. METHODS: An anonymous qualitative survey was distributed at SHC, focusing on knowledge and practice of CDI prevention guidelines, as well as education, communication, and perspectives regarding CDI at SHC. RESULTS: 112 survey responses were analyzed. Our findings unveiled gaps in personnel's knowledge of C difficile diagnostic guidelines and revealed a need for targeted communication and guideline-focused education. Health care staff shared preferences and recommendations, with the majority recommending enhanced communication of guidelines and information as a strategy for reducing CDI rates. The findings were then used to design and propose internal recommendations for SHC to mitigate the gaps found. DISCUSSION: Many guidelines and improvement strategies are based on strong scientific and medical foundations; however, it is important to ask whether these guidelines are effectively translated into practice. Frontline health care workers hold empirical perspectives that could be key in infection control. CONCLUSIONS: Our findings emphasize the importance of including frontline health care personnel in infection prevention decision-making processes and the strategies presented here can be applied to mitigating infections in different health care settings.

Impact of multimodal interventions targeting behavior change on hand hygiene adherence in nursing homes: An 18-month quasi-experimental study.

BACKGROUND: Nursing home residents are vulnerable and frail, and hand hygiene adherence is often too low to prevent transmission of infections. This study's aim was to investigate whether interventions targeting behavior change can improve hand hygiene adherence in nursing homes. METHODS: Over 18 months, 22 nursing home wards participated in this quasi-experimental study. Three intervention wards were selected based on the mean values of hand hygiene adherence, infections, and antibiotic use. Multimodal interventions targeting behavior change, including education, UV-light boxes, and posters, were implemented. RESULTS: Hand hygiene adherence increased to 60.9% in the intervention wards and decreased to 51.3% in the control wards. The control wards experienced lower adherence in all indications of WHO's "My five moments for hand hygiene." DISCUSSION: Interventions should target proper hand hygiene before patient contact and glove use because health care workers have low adherence in these areas. The findings indicate that the type of intervention is less important than attention to hand hygiene and activating workers' motivation. Using a behavior change approach and continuous reinforcement is important because the effects of interventions diminish over time. CONCLUSIONS: Our findings showed that multimodal interventions targeting behavior change may increase hand hygiene adherence.

Analysis of health care facility-onset Clostridioides difficile infection (CDI) in a hematopoietic cell transplant (HCT) unit: A call for diagnostic stewardship in a complex patient population.

Nearly half the patients identified as having health care facility-onset Clostridioides difficile infections on a hematopoietic cell transplant unit had an alternative clinical explanation for diarrhea, including conditioning regimen toxicity or other medications. Our study supports that targeted diagnostic stewardship interventions should be explored and that additional risk-adjustments considered for facilities with oncology hematopoietic cell transplant wards in the National Healthcare Safety Network LabID Clostridioides difficile infection standardized infection ratio model.

Beyond duodenoscope-transmitted infections: Analysis of surface bioburden and UV-C mitigation within a tertiary care endoscopy unit.

BACKGROUND: An inpatient endoscopy unit is a care hub for patients from throughout the hospital and can be the site of health care-associated infections (HAIs). Shared surfaces and other nonmedical devices (keyboards) have been increasingly recognized as sites of pathogen transmission. Beyond standard cleaning of high-touch target areas, we queried whether the addition of automated devices delivering low-intensity doses of ultraviolet (UV)-C radiation could further reduce bioburden in an academic endoscopy unit. METHODS: Bioburden on previously identified high-touch/communal surfaces was measured before and after the installation of automated, low-intensity UV-light emitting devices (UV Angel) that passively monitor and disinfect targeted surfaces with Ultraviolet-C light (UV-C) light. RESULTS: High-touch sites (keyboards) had a baseline bacterial contamination of >80%, whereas individual procedure rooms and common areas had a >57% contamination rate. Following the implementation of automated UV-C light decontamination, bioburden was reduced on average by >91% at high-touch surfaces and within procedure rooms. DISCUSSION/CONCLUSIONS: Nonsterile hubs of patient care could serve as sites of "silent" HAI transmission. We have identified high-touch surfaces within an endoscopy unit that have a high bioburden of bacterial contamination and demonstrated that the installation of passive, automated UV-C light disinfection devices can reduce bioburden significantly, possibly mitigating HAI transmission between patients.

Effects of COVID-19 hospitalization rates on the incidence of hospital-acquired Candida central line-associated bloodstream infection.

BACKGROUND: An increase in central line-associated bloodstream infections (CLABSIs) has been reported during the Coronavirus (COVID-19) pandemic; however, few studies have documented causative pathogens, particularly Candida species associated with candidemia. METHODS: This was a retrospective study based on the National Health Care Safety Network surveillance definitions of CLABSI caused by Candida species during pre-COVID-19 (October 2017 to February 2020) and COVID-19 (March 2020 to December 2021) periods within a local community hospital. Candida CLABSI incidence per 1,000 central line days was compared between periods using the χ2 test and correlated with COVID-19 inpatient hospitalization rates using Pearson correlation. RESULTS: Overall CLABSI (0.68 vs 1.98 per 1,000, P = .004) and Candida CLABSI incidence (0.06 vs 0.77 per 1,000, P = .003) significantly increased from pre-COVID-19 to COVID-19 periods. There was a significant correlation between COVID-19 ICU hospitalizations and CLABSIs (R = 0.18, P = .048), but not acute care hospitalizations and CLABSIs (R = 0.065, P = .250). Conversely, there was a significant association between COVID-19 acute care hospitalizations and Candida CLABSIs (R = 0.50, P < .001), but not COVID-19 ICU hospitalizations and Candida CLABSIs (R = 0.01, P = .631). CONCLUSIONS: During the COVID-19 pandemic, our facility experienced a significant increase in Candida CLABSI and a significant correlation of Candida CLABSIs with acute care COVID-19 hospitalizations.

A narrative review of how infection preventionist (IP) staffing and outcome metrics are assessed by health care organizations and factors to consider.

BACKGROUND: Infection Preventionist to date are experiencing staffing shortages, the purpose of this narrative review is to understand how heath care organizations track staffing and outcome metrics in relation to Infection Preventionists. METHODS: Databases utilized included MEDLINE, PubMed, EMBASE, Web of Science, and Google Scholar. RESULTS: The initial search included 668 studies. After excluding duplicates, the title and abstract review yielded 50 articles. After screening full texts, 37 studies met the inclusion criteria. Significant variability exists within infection prevention staffing metrics. Common metrics to account for IP staffing levels include the ratio of IPs per facility and IPs per inpatient bed. Frequently tracked outcomes in relation to infection preventionists include Catheter-associated urinary tract infections and central line bloodstream infection incidence rates and standardized infection ratios, as well as Clostridioides difficile incidence rates. Metrics and outcomes from included studies are available in our supporting tables. CONCLUSIONS: This review highlights the need for a new IP staffing model that focuses on a granular assessment of each program and care setting. Additional studies can then be conducted to examine how ideal staffing impacts outcome metrics.

Analysing the implementation of infection prevention and control measures in health care facilities during the COVID-19 pandemic in the African Region.

BACKGROUND: The declaration of SARS-CoV-2 as a public health emergency of international concern in January 2020 prompted the need to strengthen infection prevention and control (IPC) capacities within health care facilities (HCF). IPC guidelines, with standard and transmission-based precautions to be put in place to prevent the spread of SARS-CoV-2 at these HCFs were developed. Based on these IPC guidelines, a rapid assessment scorecard tool, with 14 components, to enhance assessment and improvement of IPC measures at HCFs was developed. This study assessed the level of implementation of the IPC measures in HCFs across the African Region during the COVID-19 pandemic. METHOD: An observational study was conducted from April 2020 to November 2022 in 17 countries in the African Region to monitor the progress made in implementing IPC standard and transmission-based precautions in primary-, secondary- and tertiary-level HCFs. A total of 5168 primary, secondary and tertiary HCFs were assessed. The HCFs were assessed and scored each component of the tool. Statistical analyses were done using R (version 4.2.0). RESULTS: A total of 11 564 assessments were conducted in 5153 HCFs, giving an average of 2.2 assessments per HCF. The baseline median score for the facility assessments was 60.2%. Tertiary HCFs and those dedicated to COVID-19 patients had the highest IPC scores. Tertiary-level HCFs had a median score of 70%, secondary-level HCFs 62.3% and primary-level HCFs 56.8%. HCFs dedicated to COVID-19 patients had the highest scores, with a median of 68.2%, followed by the mixed facilities that attended to both COVID-19 and non-COVID-19 patients, with 64.84%. On the components, there was a strong correlation between high IPC assessment scores and the presence of IPC focal points in HCFs, the availability of IPC guidelines in HCFs and HCFs that had all their health workers trained in basic IPC. CONCLUSION: In conclusion, a functional IPC programme with a dedicated focal person is a prerequisite for implementing improved IPC measures at the HCF level. In the absence of an epidemic, the general IPC standards in HCFs are low, as evidenced by the low scores in the non-COVID-19 treatment centres.

Mortality and Case Fatality Rates Associated With Surgical Site Infections: A Retrospective Surveillance Study.

Background: Surgical site infections (SSIs) have been associated with increases in terms of costs, hospital stay, morbidity, and mortality. We aimed to assess trends in SSIs monitored through 10 years of surveillance activities in our region, and to describe mortality attributable to SSIs in the two most frequently monitored surgical procedures: colorectal surgery and hip arthroplasty. Methods: A retrospective cohort study was conducted among the 42 hospitals participating in the surveillance network of our region in northern Italy. All colorectal and hip arthroplasty procedures performed between January 1st, 2010, and December 31st, 2019, and monitored through the surveillance system were included in the study. Surgical site infection rates, overall mortality, case fatality rates (CFR), and mortality attributable to SSIs were evaluated overall and by year of participation in the surveillance program. Results: In total, 11,417 colon surgery and 20,804 hip arthroplasty procedures were included. Among colon surgery procedures, SSI rates decreased from 9.21% in 2010 to 5.7% in 2019. A significant decreasing trend was found for overall mortality (p = 0.008), which progressively decreased from 4.96% in 2010 to 2.96% in 2019. Among hip arthroplasty procedures, no significant trend emerged for SSI and mortality rates. Considering the 10-year period, the CFR was 6.62% and 3.7% for SSIs after colon surgery and hip arthroplasty procedures, respectively. Conclusions: The impact of SSIs on the clinical outcomes of patients undergoing surgery highlights the importance of SSI surveillance.

Voices from frontline nurses on care quality and patient safety during COVID-19: An application of the Donabedian model.

BACKGROUND: The COVID-19 pandemic has adversely impacted quality of care and patient safety. This study aimed to describe registered nurses' (RNs) perceptions on the impact of the COVID-19 pandemic on their ability to adhere to patient safety protocols using Donabedian's Health Care Quality model. METHODS: In October 2020, a survey was conducted among all actively licensed RNs in New Jersey who provided direct patient care during the first peak of COVID-19. RESULTS: Of 3,027 participants, 68% reported that the number of patients assigned impacted their ability to adhere to protocols. RNs identified a variety of organizational structures impacting adherence, including inadequate staffing, staff qualifications, and inadequate resources. Impacted processes included the inability to adhere to patient safety protocols and conduct comprehensive assessments and surveillance, the need for additional time spent on personal protective equipment and isolation policies, and difficulty maintaining isolation integrity; the need to prioritize and cluster care; and guidelines limiting personnel who could enter the room. Nurses attributed both adverse patient and staff outcomes to inadequate staffing and high patient acuity. CONCLUSIONS: These findings highlight the need for health care organizations to support frontline nursing staff in adhering to patient safety and infection prevention and control protocols during times of crises. Infection preventionists have substantial contact with bedside nurses and should leverage their collegial relationships to promote patient safety.

Effect of serious infectious threat response initiative (SITRI) during the coronavirus disease 2019 (COVID-19) pandemic at the Veterans Affairs North Texas Health Care System.

BACKGROUND: Health care-associated infections (HAIs) increased worldwide as health care facilities struggled through the pandemic. We describe our methods in the implementation of a programmatic initiative called serious infectious threat response initiative (SITRI) that was conceptualized to support our staff, to facilitate day-to-day clinical operations related to COVID-19 and to shield our infection prevention and control program (IPC) from excessive COVID-19 work burden to the extent possible to retain routine prevention focused efforts. Post implementation, we sought to understand and quantify the workload and utility of SITRI, IPC burnout and HAI incidence during the implementation period. METHODS: We correlated the number of weekly phone calls with inpatient COVID-19 census, assessed types of calls, staff feedback, IPC burnout, pre- and postpandemic HAI incidence, and the cost. RESULTS: There was significant correlation between SITRI calls and the weekly average COVID-19 census (P = .00026). IPC burnout evaluation indicated improvement in scores for exhaustion and reduced achievement and worsening in score for depersonalization. HAI incidence did not increase. SITRI's cost was $360,000. CONCLUSIONS: Staff solicited SITRI's support in tandem with the COVID-19 burden. Our HAI during the pandemic did not increase while SITRI was operational in contrast to what is published in literature.

Isolation and Detection of Drug-Resistant Bacterial Pathogens in Postoperative Wound Infections at a Tertiary Care Hospital in Saudi Arabia.

Background: Surgical site infections (SSIs), especially when caused by multidrug-resistant (MDR) bacteria, are a major healthcare concern worldwide. For optimal treatment and prevention of antimicrobial resistance, it is important for clinicians to be aware of local drug-resistant bacterial pathogens that cause SSIs. Objective: To determine the frequency patterns of drug-resistant bacterial strains causing SSIs at a tertiary care hospital in Saudi Arabia. Methods: This retrospective study was conducted at the Microbiology laboratory of Al-Noor Specialist Hospital, Makkah, Saudi Arabia, and included wound swab samples from all cases of SSI between January 01, 2017, and December 31, 2021. The swabs were processed for the identification of bacterial strains and their resistance pattern to antibiotics according to the Clinical and Laboratory Standards Institute. Results: A total of 5409 wound swabs were analyzed, of which 3604 samples (66.6%) were from male. Most samples were from the Department of Surgery (43.3%). A total of 14 bacterial strains were isolated, of which 9 were Gram-negative bacteria. The most common isolates were Klebsiella pneumoniae, followed by Pseudomonas aeruginosa, Escherichia coli, Acinetobacter baumannii, methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococci (VRE), and vancomycin-resistant S. aureus (VRSA). In terms of MDR in 2021, the highest rate of carbapenem-resistance was in A. baumannii (97%). MDR was as follows: A. baumannii, 97%; K. pneumoniae, 81%; E. coli, 71%; MRSA, 60%; P. aeruginosa, 33%; VRE, 22%; and VRSA, 2%. Conclusion: This study showed that in the city of Makkah, Saudi Arabia, the rates of MDR bacteria are high, with the majority being Gram-negative.

Polish infection control nurses' job satisfaction and cooperation with their colleagues reflect how the value of infection control is appreciated by other health care workers: findings from surveys conducted before and during the COVID-19 pandemic.

BACKGROUND: Infection prevention and control (IPC) is based on the activity of specialized, trained and highly qualified personnel, especially infection control nurses (ICNs). Effective implementation of IPC procedures demands close cooperation between IPC teams (IPCTs) and hospital personnel. Based on disturbing results on the epidemiology of health care-associated infections (HAIs) and compliance with preventive procedures, we suspect that cooperation between ICNs and different groups of hospital staff is poor. The aim of this study was to assess the perceptions of ICNs working in Polish hospitals with regard to difficulties in working with various professional groups in the hospital, their organizational conditions, and their job satisfaction before and after the COVID-19 pandemic. METHODS: The study was conducted twice, in 2014 and 2021, among ICNs working in Polish hospitals. The survey used an anonymous questionnaire designed by the authors. RESULTS: In 2014, 183 ICNs participated in the study, and 175 ICNs participated in 2021. The respondents' average age and seniority (duration of work as an ICN) were higher in 2021. Depending on the ward specialty, approximately 30-48.8% of the ICNs had difficulty cooperating with physicians. However, the ICNs declared better cooperation with nurses in various hospital wards and with other professionals. For some groups of hospital staff, there was a negative correlation between poor cooperation and ICNs' job satisfaction. The job satisfaction data were disturbing; for example, more than half of the respondents considered changing jobs, and the lack of a sense of purpose in their work was declared by 29.7% of ICNs in 2014 and by 54.3% of ICNs in 2021. CONCLUSIONS: Our results suggest that infection prevention and control is not highly appreciated by health care workers and hospital management. Our study reveals difficulties in ICNs' cooperation with hospital staff and managers in both 2021 and 2014, moderate job satisfaction, a high level of willingness to change jobs, and insufficient training in interpersonal skills and the implementation of changes. These findings clearly indicate an urgent need to introduce modern competence development systems in infection control beyond the scope of traditional training.

Improvement in Infection Prevention and Control Performance Following Operational Research in Sierra Leone: A Before (2021) and After (2023) Study.

INTRODUCTION: Infection prevention and control (IPC) is crucial to limit health care-associated infections and antimicrobial resistance. An operational research study conducted in Sierra Leone in 2021 reported sub-optimal IPC performance and provided actionable recommendations for improvement. METHODS: This was a before-and-after study involving the national IPC unit and all twelve district-level secondary public hospitals. IPC performance in 2021 (before) and in 2023 (after) was assessed using standardized World Health Organization checklists. IPC performance was graded as: inadequate (0-25%), basic (25.1-50%), intermediate (50.1-75%), and advanced (75.1-100%). RESULTS: The overall IPC performance in the national IPC unit moved from intermediate (58%) to advanced (78%), with improvements in all six core components. Four out of six components achieved advanced levels when compared to the 2021 levels. The median score for hospitals moved from basic (50%) to intermediate (59%), with improvements in six of eight components. Three of four gaps identified in 2021 at the national IPC unit and four of seven at hospitals had been addressed by 2023. CONCLUSIONS: The study highlights the role of operational research in informing actions that improved IPC performance. There is a need to embed operational research as part of the routine monitoring of IPC programs.

Health Care-Associated Infection in Elderly Patients With Cerebrovascular Disease in Intensive Care Units: A Retrospective Cohort Study in Taizhou, China.

BACKGROUND: Cerebrovascular diseases are associated with high incidence of health care-associated infections (HAIs) and poor prognosis in elderly patients. This study aimed to investigate the incidence and clinical characteristics of HAIs in elderly patients with cerebrovascular disease in the intensive care unit (ICU). METHODS: Patients admitted with cerebrovascular disease, aged ≥65 years, were included. The clinical data of the patients were retrospectively analyzed to determine the risk factors, infection type, distribution, and pathogenic characteristics of HAIs in the context of cerebrovascular diseases. RESULTS: Out of 381 ICU inpatients monitored, 79 (20.73%) developed HAIs. Risk analysis revealed number of ventilator days as significant risk factors for HAIs in elderly patients with cerebrovascular diseases in the comprehensive ICU. In the HAI group, 56 patients (70.89%) had respiratory tract infection (RTI). Sixty-five patients (82.28%) were infected with Gram-negative bacteria (GNB), and 42 (53.16%) with multi-drug-resistant organism (MDRO). The length of hospitalization days, ventilator days, and overall hospitalization costs were higher in the HAI group than in the non-HAI group (P < 0.05), but there was no significant difference between groups in the treatment outcome of patients. Patients with MDRO infection had longer duration and higher cost of hospitalization than those infected with non-MDRO (P < 0.05), but there was no significant difference between the groups in the treatment outcome of patients. CONCLUSIONS: HAIs occurred mostly due to RTI and GNB infection. The hospitalization cost and duration, as well as the length of ventilator days, were higher for cerebrovascular patients with HAIs than for non-HAIs patients.

Most hospital patients at risk for bacterial infection undergo an anesthetic: implications for infection control practices related to the anesthesia workspace.

PURPOSE: Even with nearly 100% compliance with prophylactic antibiotic protocols, many surgical patients (> 5%) develop surgical site infections, some caused by pathogens transmitted from the anesthesia workspace (e.g., anesthesia machine), including multidrug-resistant Staphylococcus aureus. Reducing contamination of the anesthesia workspace substantively reduces the risk of surgical site infections. We estimated the percentage of hospital patients at risk for health care-associated infections who may benefit from the application of basic preventive measures under the control of anesthesia practitioners (e.g., their hand hygiene). METHODS: We conducted a retrospective cohort study which included every patient admitted to the University of Miami Health System from April 2021 through March 2022 for hospitalization, surgery, emergency department visits, or outpatient visits. Lists were created for the start date and times of every parenteral antibiotic administered and every anesthetic. RESULTS: Among 28,213 patient encounters including parenteral antibiotic(s), more than half (64.3%) also included an anesthetic (99% confidence interval, 62.2 to 66.6). The hypothesis that most antibiotics were administered during encounters when a patient underwent an anesthetic was accepted (P < 0.001). This observation may seem counterintuitive because parenteral antibiotics were administered for fewer than half of the 53,235 anesthetics (34.2%). The result was a consequence of most anesthetics (63.5%) at the health system being conducted in nonoperating room locations, and only 7.2% of such patients received a parenteral antibiotic. CONCLUSIONS: Because approximately two-thirds of patients who receive an intravenous antibiotic also undergo an anesthetic, greater use of effective infection control measures in the anesthesia operating room workspace has the potential to substantively reduce overall rates of hospital infections.

RéSUMé: OBJECTIF: Même avec un respect de près de 100 % des protocoles antibiotiques prophylactiques, bon nombre de patients et patientes en chirurgie (> 5 %) développent des infections du site opératoire, dont certaines sont causées par des agents pathogènes transmis par l'espace de travail anesthésique (p. ex. appareil d'anesthésie), y compris un staphylocoque doré multirésistant. La réduction de la contamination de l'espace de travail anesthésique réduit considérablement le risque d'infections du site opératoire. Nous avons estimé le pourcentage de patientes et patients hospitalisé·es à risque d'infections associées aux soins de santé qui pourraient bénéficier de l'application de mesures préventives de base sous le contrôle de praticiens et praticiennes d'anesthésie (par exemple, leur hygiène des mains). MéTHODE: Nous avons mené une étude de cohorte rétrospective qui comprenait toutes les personnes admises au Système de santé de l'Université de Miami d'avril 2021 à mars 2022 pour une hospitalisation, une intervention chirurgicale, des visites aux urgences ou des consultations externes. Des listes ont été créées pour la date et l'heure de début de chaque antibiotique parentéral administré et de chaque anesthésique. RéSULTATS: Parmi les 28 213 consultations avec les patient·es comprenant des antibiotiques parentéraux, plus de la moitié (64,3 %) comportaient également un anesthésique (intervalle de confiance à 99 %, 62,2 à 66,6). L'hypothèse selon laquelle la plupart des antibiotiques étaient administrés lors de rencontres lorsqu'une personne bénéficiait d'une anesthésie a été acceptée (P < 0,001). Cette observation peut sembler contre-intuitive, car des antibiotiques parentéraux ont été administrés pour moins de la moitié des 53 235 anesthésiques (34,2 %). En effet, la plupart des anesthésies (63,5 %) ont été administrées en dehors de la salle d'opération, et seulement 7,2 % de cette patientèle a reçu un antibiotique parentéral. CONCLUSION: Étant donné qu'environ les deux tiers des patientes et patients qui reçoivent un antibiotique par voie intraveineuse bénéficient également d'une anesthésie, une plus grande utilisation de mesures efficaces de contrôle des infections dans l'espace de travail anesthésique de la salle d'opération pourrait réduire considérablement les taux globaux d'infections hospitalières.
