RESUMO
OBJECTIVE: To determine the effectiveness of active, upper-room, germicidal ultraviolet (GUV) devices in reducing bacterial contamination in patient rooms in air and on surfaces as a supplement to the central heating, ventilation, and air conditioning (HVAC) air handling unit (AHU) with MERV 14 filters and UV-C disinfection. METHODS: This study was conducted in an academic medical center, burn intensive care unit (BICU), for 4 months in 2022. Room occupancy was monitored and recorded. In total, 402 preinstallation and postinstallation bacterial air and non-high-touch surface samples were obtained from 10 BICU patient rooms. Airborne particle counts were measured in the rooms, and bacterial air samples were obtained from the patient-room supply air vents and outdoor air, before and after the intervention. After preintervention samples were obtained, an active, upper-room, GUV air disinfection system was deployed in each of the patient rooms in the BICU. RESULTS: The average levels of airborne bacteria of 395 CFU/m3 before GUV device installation and 37 CFU/m3 after installation indicated an 89% overall decrease (P < .0001). Levels of surface-borne bacteria were associated with a 69% decrease (P < .0001) after GUV device installation. Outdoor levels of airborne bacteria averaged 341 CFU/m3 in March before installation and 676 CFU/m3 in June after installation, but this increase was not significant (P = .517). CONCLUSIONS: Significant reductions in air and surface contamination occurred in all rooms and areas and were not associated with variations in outdoor air concentrations of bacteria. The significant decrease of surface bacteria is an unexpected benefit associated with in-room GUV air disinfection, which can potentially reduce overall bioburden.

The built environment has been integral to response to the global pandemic of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). In particular, engineering controls to mitigate risk of exposure to SARS-CoV-2 and other newly emergent respiratory pathogens in the future will be important. Anticipating emergence from this pandemic, or at least adaptation given increasing administration of effective vaccines, and the safety of patients, personnel, and others in health care facilities remain the core goals. This article summarizes known risks and highlights prevention strategies for daily care as well as response to emergent infectious diseases and this parapandemic phase.

Portable medical equipment (PME) can be an important reservoir of pathogens causing health care-associated infections. To address this, a novel, portable ultraviolet disinfection pod (UVDP) that allows for full 360-degree disinfection was developed. This investigation examined efficacy of the UVDP against microorganisms on clean, patient-ready PME. We found that the UVDP significantly reduced the number of recoverable bacteria on PME.

Background: Many hospitals struggle to prevent catheter-associated urinary tract infection (CAUTI). Objective: To evaluate the effect of a multimodal initiative on CAUTI in hospitals with high burden of health care-associated infection (HAI). Design: Prospective, national, nonrandomized, clustered, externally facilitated, pre-post observational quality improvement initiative, for 3 cohorts active between November 2016 and May 2018. Setting: Acute care, long-term acute care, and critical access hospitals, including intensive care and non-intensive care wards. Participants: Target hospitals had a high burden of Clostridioides difficile infection plus central line-associated bloodstream infection, CAUTI, or hospital-onset methicillin-resistant Staphylococcus aureus bloodstream infection, defined as cumulative attributable differences above the first tertile in the Targeted Assessment for Prevention (TAP) strategy. Some additional nonrecruited hospitals also joined. Intervention: Multimodal intervention, including Practice Change Assessment tool to identify infection prevention and control (IPC) and HAI prevention gaps; Web-based, on-demand modules involving onboarding, foundational IPC practices, HAI-specific 2-tiered approach to prioritize and implement interventions, and TAP resources; monthly webinars; state partner-led in-person meetings; and feedback. State partners made site visits to at least 50% of their enrolled hospitals, to support self-assessments and coach. Measurements: Rates of CAUTI and urinary catheter device utilization ratio. Results: Of 387 participating hospitals from 23 states and the District of Columbia, 361 provided CAUTI data. Over the study period, the unadjusted CAUTI rate was low and relatively stable, decreasing slightly from 1.12 to 1.04 CAUTIs per 1000 catheter-days. Catheter utilization decreased from 21.46 to 19.83 catheter-days per 100 patient-days from the pre- to the postintervention period. Limitations: The intervention period was brief, with no assessment of fidelity. Baseline CAUTI rates were low. Patient characteristics were not assessed. Conclusion: This multimodal intervention yielded no substantial improvements in CAUTI or urinary catheter utilization. Primary Funding Source: Centers for Disease Control and Prevention.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) remains one of the most common causes of health care-associated infection (HAI). Objective: To evaluate the effect of education and a tiered, evidence-based infection prevention strategy on rates of hospital-onset MRSA bloodstream infection (BSI). Design: Prospective, national, nonrandomized, interventional, 12-month, multiple cohort, pre-post observational quality improvement project. Setting: Acute care, long-term acute care, and critical access hospitals with a disproportionate burden of HAI. Patients: All patients admitted to participating facilities during the project period. Intervention: A multimodal infection prevention intervention consisting of recommendations and tools for prioritizing and implementing evidence-based infection prevention strategies, on-demand educational videos, Internet-based live educational presentations, and access to content experts. Measurements: Rates of hospital-onset MRSA BSI, overall and stratified by hospital type, during 12-month baseline and postintervention periods. Variation in outcomes across hospital types was examined. Results: Between November 2016 and May 2018, 387 hospitals in 23 states and the District of Columbia participated, 353 (91%) submitted MRSA data, and 172 (49%) indicated that MRSA prevention was a priority. Unadjusted overall rates of hospital-onset MRSA BSI were 0.075 (95% CI, 0.065 to 0.085) and 0.071 (CI, 0.063 to 0.080) per 1000 patient-days in the baseline and postintervention periods, respectively. Limitations: The intervention period was short. Participation and adherence to recommended interventions were not fully assessed. Baseline rates of hospital-onset MRSA BSI were relatively low. Prevention of MRSA was a priority in a minority of participating hospitals. Patient characteristics and other MRSA risk factors were not assessed. Conclusion: In hospitals with a disproportionate burden of HAIs, access to tools to assist with implementation of evidence-based prevention strategies and education resources alone may not be sufficient to prevent MRSA BSI.

BACKGROUND: In the postacute and long-term care setting, the practice of changing the indwelling urinary catheter large sterile drainage bag to a small-size leg drainage bag is intended to maintain a person's mobility, dignity, and comfort. There is scant evidence that assesses the impact of intermittent use of a leg bag on frequency of urinary tract infection since this breaks the closed urinary drainage system. METHODS: We reviewed research published between 1993 and 2014 for the answers to 20 practice questions developed by experts and long-term care clinicians on the risks and benefits, cleaning, connection, and storage of reusable leg bags. RESULTS: Seventeen of the 26 publications and studies provided varying advice on the risk of breaking the closed system and on practices for changing, disinfecting, and storing leg bags between uses. Thirteen of 20 practice questions were answered by ≥1 publications, few of which were evidence based. CONCLUSIONS: We identified the existence of low-level evidence that leg bags pose no evident, disproportionate risk of infection compared with maintaining a closed system. The lack of uniformity in evidence in the literature suggests aseptic technique should guide practice. Available evidence suggests that aseptic technique should guide practice.

BACKGROUND: Infection Preventionists have varying levels of educational preparation. Many have no prior experience in IP. The diversity makes design of professional development programs challenging. Recent surveys suggest that only about half of practicing IPs are board certified. There is an urgent need to employ competent IP's to drive improvement in patient outcomes. METHODS: This is a project that utilized the APIC Competency Model to create a professional development program characterizing three career stages. Methods included a review of literature on professional development; a survey of IP competence; an assessment of job descriptions and performance evaluations; and a crosswalk of IP competencies. RESULTS: The professional development program includes competency - based IP job descriptions and performance evaluations for each career stage; a professional portfolio; and a toolkit for supervisors. DISCUSSION: Participants agreed that application of the model resulted in tools which are more closely aligned with current roles for IPs; and increased satisfaction and motivation with the new program. CONCLUSION: Competent and knowledgeable IP's are crucial to optimizing efficacy of IPC programs. A professional development program has the potential to guide staff orientation, improve satisfaction and retention, improve patient outcomes and promote a positive trajectory in advancing practice.

Importance: Catheter-associated urinary tract infection (UTI) in nursing home residents is a common cause of sepsis, hospital admission, and antimicrobial use leading to colonization with multidrug-resistant organisms. Objective: To develop, implement, and evaluate an intervention to reduce catheter-associated UTI. Design, Setting, and Participants: A large-scale prospective implementation project was conducted in community-based nursing homes participating in the Agency for Healthcare Research and Quality Safety Program for Long-Term Care. Nursing homes across 48 states, Washington DC, and Puerto Rico participated. Implementation of the project was conducted between March 1, 2014, and August 31, 2016. Interventions: The project was implemented over 12-month cohorts and included a technical bundle: catheter removal, aseptic insertion, using regular assessments, training for catheter care, and incontinence care planning, as well as a socioadaptive bundle emphasizing leadership, resident and family engagement, and effective communication. Main Outcomes and Measures: Urinary catheter use and catheter-associated UTI rates using National Healthcare Safety Network definitions were collected. Facility-level urine culture order rates were also obtained. Random-effects negative binomial regression models were used to examine changes in catheter-associated UTI, catheter utilization, and urine cultures and adjusted for covariates including ownership, bed size, provision of subacute care, 5-star rating, presence of an infection control committee, and an infection preventionist. Results: In 4 cohorts over 30 months, 568 community-based nursing homes were recruited; 404 met inclusion criteria for analysis. The unadjusted catheter-associated UTI rates decreased from 6.78 to 2.63 infections per 1000 catheter-days. With use of the regression model and adjustment for facility characteristics, the rates decreased from 6.42 to 3.33 (incidence rate ratio [IRR], 0.46; 95% CI, 0.36-0.58; P < .001). Catheter utilization was 4.5% at baseline and 4.9% at the end of the project. Catheter utilization remained unchanged (4.50 at baseline, 4.45 at conclusion of project; IRR, 0.95; 95% CI, 0.88-1.03; P = .26) in adjusted analyses. The number of urine cultures ordered for all residents decreased from 3.49 per 1000 resident-days to 3.08 per 1000 resident-days. Similarly, after adjustment, the rates were shown to decrease from 3.52 to 3.09 (IRR, 0.85; 95% CI, 0.77-0.94; P = .001). Conclusions and Relevance: In a large-scale, national implementation project involving community-based nursing homes, combined technical and socioadaptive catheter-associated UTI prevention interventions successfully reduced the incidence of catheter-associated UTIs.

BACKGROUND: The Agency for Healthcare Research and Quality (AHRQ) has funded national collaboratives using the Comprehensive Unit-based Safety Program to reduce rates of two catheter-associated infections-central-line-associated bloodstream infection (CLABSI) and catheter-associated urinary tract infection (CAUTI), using evidence-based intervention bundles to improve technical aspects of care and socioadaptive approaches to foster a culture of safety. OBJECTIVE: Examine the association between hospital units' results for the Hospital Survey on Patient Safety Culture (HSOPS) and catheter-associated infection rates. METHODS: We analysed data from two prospective cohort studies from acute-care intensive care units (ICUs) and non-ICUs participating in the AHRQ CLABSI and CAUTI collaboratives. National Healthcare Safety Network catheter-associated infections per 1000 catheter-days were collected at baseline and quarterly postimplementation. The HSOPS was collected at baseline and again 1â year later. Infection rates were modelled using multilevel negative binomial models as a function of HSOPS components over time, adjusted for hospital-level characteristics. RESULTS: 1821 units from 1079 hospitals (CLABSI) and 1576 units from 949 hospitals (CAUTI) were included. Among responding units, infection rates declined over the project periods (by 47% for CLABSI, by 23% for CAUTI, unadjusted). No significant associations were found between CLABSI or CAUTI rates and HSOPS measures at baseline or over time. CONCLUSIONS: We found no association between results of the HSOPS and catheter-associated infection rates when measured at baseline and postintervention in two successful large national collaboratives focused on prevention of CLABSI and CAUTI. These results suggest that it may be possible to improve CLABSI and CAUTI rates without making significant changes in safety culture, particularly as measured by instruments like HSOPS.

The built environment supports the safe care of patients in health care facilities. Infection preventionists and health care epidemiologists have expertise in prevention and control of health care-associated infections (HAIs) and assist with designing and constructing facilities to prevent HAIs. However, design elements are often missing from initial concepts. In addition, there is a large body of evidence that implicates construction and renovation as being associated with clusters of HAIs, many of which are life threatening for select patient populations. This article summarizes known risks and prevention strategies within a framework for patient safety.

BACKGROUND: The purpose of this study was to assess effectiveness of an interactive educational program in increasing knowledge of key infection prevention and control (IPC) principles with emphasis on indwelling device care, hand hygiene, and multidrug-resistant organisms (MDROs) among nursing home (NH) health care personnel (HCP). METHODS: We conducted a multimodal randomized controlled study involving HCP at 12 NHs. Ten comprehensive and interactive modules covered common IPC topics. We compared intervention and control scores to assess differences in pretest scores as a result of field interventions, pre- and post-test scores to assess knowledge gain, and magnitude of knowledge gain based on job categories. RESULTS: We conducted over 200 in-services across 10 topics at six intervention sites over 36 months. There were 4,962 tests returned over the course of the study, ranging from 389-633 per module. Participants were mostly female certified nursing assistants (CNAs). Score improvement was highest for modules emphasizing hand hygiene, urinary catheter care, and MDROs (15.6%, 15.9%, and 22.0%, respectively). After adjusting for cluster study design, knowledge scores were significantly higher after each educational module, suggesting the education delivery method was effective. When compared with CNAs, nursing and rehabilitation personnel scored significantly higher in their knowledge tests. CONCLUSIONS: Our intervention significantly improved IPC knowledge in HCP, especially for those involved in direct patient care. This increase in knowledge along with preemptive barrier precautions and active surveillance has enhanced resident safety by reducing MDROs and infections in high-risk NH residents.

Catheter-associated urinary tract infection (CAUTI) is considered a reasonably preventable event in the hospital setting, and it has been included in the US Department of Health and Human Services National Action Plan to Prevent Healthcare-Associated Infections. While multiple definitions for measuring CAUTI exist, each has important limitations, and understanding these limitations is important to both clinical practice and policy decisions. The National Healthcare Safety Network (NHSN) surveillance definition, the most frequently used outcome measure for CAUTI prevention efforts, has limited clinical correlation and does not necessarily reflect noninfectious harms related to the catheter. We advocate use of the device utilization ratio (DUR) as an additional performance measure for potential urinary catheter harm. The DUR is patient-centered and objective and is currently captured as part of NHSN reporting. Furthermore, these data are readily obtainable from electronic medical records. The DUR also provides a more direct reflection of improvement efforts focused on reducing inappropriate urinary catheter use.

IMPORTANCE: Indwelling devices (eg, urinary catheters and feeding tubes) are often used in nursing homes (NHs). Inadequate care of residents with these devices contributes to high rates of multidrug-resistant organisms (MDROs) and device-related infections in NHs. OBJECTIVE: To test whether a multimodal targeted infection program (TIP) reduces the prevalence of MDROs and incident device-related infections. DESIGN, SETTING, AND PARTICIPANTS: Randomized clinical trial at 12 community-based NHs from May 2010 to April 2013. Participants were high-risk NH residents with urinary catheters, feeding tubes, or both. INTERVENTIONS: Multimodal, including preemptive barrier precautions, active surveillance for MDROs and infections, and NH staff education. MAIN OUTCOMES AND MEASURES: The primary outcome was the prevalence density rate of MDROs, defined as the total number of MDROs isolated per visit averaged over the duration of a resident's participation. Secondary outcomes included new MDRO acquisitions and new clinically defined device-associated infections. Data were analyzed using a mixed-effects multilevel Poisson regression model (primary outcome) and a Cox proportional hazards model (secondary outcome), adjusting for facility-level clustering and resident-level variables. RESULTS: In total, 418 NH residents with indwelling devices were enrolled, with 34,174 device-days and 6557 anatomic sites sampled. Intervention NHs had a decrease in the overall MDRO prevalence density (rate ratio, 0.77; 95% CI, 0.62-0.94). The rate of new methicillin-resistant Staphylococcus aureus acquisitions was lower in the intervention group than in the control group (rate ratio, 0.78; 95% CI, 0.64-0.96). Hazard ratios for the first and all (including recurrent) clinically defined catheter-associated urinary tract infections were 0.54 (95% CI, 0.30-0.97) and 0.69 (95% CI, 0.49-0.99), respectively, in the intervention group and the control group. There were no reductions in new vancomycin-resistant enterococci or resistant gram-negative bacilli acquisitions or in new feeding tube-associated pneumonias or skin and soft-tissue infections. CONCLUSIONS AND RELEVANCE: Our multimodal TIP intervention reduced the overall MDRO prevalence density, new methicillin-resistant S aureus acquisitions, and clinically defined catheter-associated urinary tract infection rates in high-risk NH residents with indwelling devices. Further studies are needed to evaluate the cost-effectiveness of this approach as well as its effects on the reduction of MDRO transmission to other residents, on the environment, and on referring hospitals.
