RESUMO
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.

Rationale: Hunter-Cheyne-Stokes breathing with central sleep apnea (CSA) is prevalent in some patients with heart failure with reduced ejection fraction (HFrEF). Theoretical models of Hunter-Cheyne-Stokes breathing predict that a low metabolic rate (MR) predisposes one to CSA. Objectives: In this study, we examined the role of MR in the pathogenesis of CSA. Methods: A physiological study was conducted in a sleep laboratory at a U.S. Department of Veterans Affairs medical center. Patients were 28 consecutive male Veterans with stable HFrEF. After an adaptation night, polysomnography, left ventricular ejection fraction, pulmonary function tests, carbon dioxide production ([Formula: see text]), and arterial blood samples were obtained under strict standardized conditions. Physiological variables were then entered into regression models to examine the association with CSA. Results: Body mass index varied from 20 to 40 kg/m2, and [Formula: see text] ranged from 167 to 434 ml/min. In the final regression model, low [Formula: see text] and low body mass index were associated with CSA index. [Formula: see text] had the strongest association (95% confidence interval, -0.36 to -0.06; P = 0.007). Conclusions: In patients with HFrEF, a low MR and related low [Formula: see text], but not low oxygen consumption, were associated with CSA. Mechanistically, in the face of low MR and [Formula: see text], a given change in ventilation results in large swings in partial pressure of CO2, thus promoting CSA. To our knowledge, this is the first study in humans that shows this association.

We detected no correlation between standardized antimicrobial administration ratios (SAARs) and healthcare facility-onset Clostridioides difficile infection (HO-CDI) rates in 102 acute-care Veterans Affairs medical centers over 16 months. SAARs may be useful for investigating trends in local antimicrobial use, but no ratio threshold demarcated HO-CDI risk.

A comparison of computer-extracted and facility-reported counts of hospitalized coronavirus disease 2019 (COVID-19) patients for public health reporting at 36 hospitals revealed 42% of days with matching counts between the data sources. Miscategorization of suspect cases was a primary driver of discordance. Clear reporting definitions and data validation facilitate emerging disease surveillance.

OBJECTIVE: To assess the impact of the coronavirus disease 2019 (COVID-19) pandemic on healthcare-associated infections (HAIs) reported from 128 acute-care and 132 long-term care Veterans Affairs (VA) facilities. METHODS: We compared central-line-associated bloodstream infections (CLABSIs), ventilator-associated events (VAEs), catheter-associated urinary tract infections (CAUTIs), methicillin-resistant Staphylococcus aureus (MRSA), and Clostridioides difficile infections and rates reported from each facility monthly to a centralized database before the pandemic (February 2019 through January 2020) and during the pandemic (July 2020 through June 2021). RESULTS: Nationwide VA COVID-19 admissions peaked in January 2021. Significant increases in the rates of CLABSIs, VAEs, and MRSA all-site HAIs (but not MRSA CLABSIs) were observed during the pandemic in acute-care facilities. There was no significant change in CAUTI rates, and C. difficile rates significantly decreased. There were no significant increases in HAIs in long-term care facilities. CONCLUSIONS: The COVID-19 pandemic had a differential impact on HAIs of various types in VA acute care, with many rates increasing. The decrease in CDI HAIs may be due, in part, to evolving diagnostic testing. The minimal impact of COVID-19 in VA long-term facilities may reflect differences in patient numbers and acuity and early recognition of the impact of the pandemic on nursing home residents leading to increased vigilance and optimization of infection prevention and control practices in that setting. These data support the need for building and sustaining conventional infection prevention and control strategies before and during a pandemic.

Legionella growth in healthcare building water systems can result in legionellosis, making water management programs (WMPs) important for patient safety. However, knowledge is limited on Legionella prevalence in healthcare buildings. A dataset of quarterly water testing in Veterans Health Administration (VHA) healthcare buildings was used to examine national environmental Legionella prevalence from 2015 to 2018. Bayesian hierarchical logistic regression modeling assessed factors influencing Legionella positivity. The master dataset included 201,146 water samples from 814 buildings at 168 VHA campuses. Overall Legionella positivity over the 4 years decreased from 7.2 to 5.1%, with the odds of a Legionella-positive sample being 0.94 (0.90-0.97) times the odds of a positive sample in the previous quarter for the 16 quarters of the 4 year period. Positivity varied considerably more at the medical center campus level compared to regional levels or to the building level where controls are typically applied. We found higher odds of Legionella detection in older buildings (OR 0.92 [0.86-0.98] for each more recent decade of construction), in taller buildings (OR 1.20 [1.13-1.27] for each additional floor), in hot water samples (O.R. 1.21 [1.16-1.27]), and in samples with lower residual biocide concentrations. This comprehensive healthcare building review showed reduced Legionella detection in the VHA healthcare system over time. Insights into factors associated with Legionella positivity provide information for healthcare systems implementing WMPs and for organizations setting standards and regulations.

We sought to determine how often patients with a negative toxin enzyme immunoassay following a positive nucleic acid amplification test for Clostridioides difficile infection (CDI) were treated for CDI in Veterans Affairs facilities. From October 2018 through March 2021, 702 (29.5%) of 2,374 unique patients with these test results were treated.

BACKGROUND AND OBJECTIVES: Research on Legionnaires' Disease (LD) suggests there may be long-term health complications, but data are limited. This study investigated whether Intensive Care Unit (ICU) admission during LD hospitalization may be associated with adverse health outcomes and characterized subsequent discharge diagnoses in patients with LD up to 5 years post-LD. METHODS: We conducted a retrospective case series study with follow up for 5 years among patients hospitalized at a Department of Veterans Affairs (VA) Medical Center between 2005 and 2010 with LD. Data were collected from medical records on health history, LD severity (including ICU admission), and discharge diagnoses for 5 years post-LD or until death. We used ordinal logistic regression to explore associations between ICU admission and hospitalizations post-LD. Frequency counts were used to determine the most prevalent discharge diagnoses in the 5 years post-LD. RESULTS: For the 292 patients with laboratory-confirmed LD, those admitted to the ICU during LD hospitalization were more likely to have a greater number of hospitalizations within 5 years compared to non-ICU patients (ORHosp 1.92 CI95% 1.25, 2.95). Fifty-five percent (161/292) had ≥ 1 hospitalization within 5 years post-LD. After accounting for pre-existing diagnosis codes in patients with at least one hospitalization in the 2 years prior to LD (n = 77/161 patients, 47.8%), three of the four most frequent new diagnoses in the 5 years post-LD were non-chronic conditions: acute renal failure (n = 22, 28.6%), acute respiratory failure (n = 17, 22.1%) and unspecified pneumonia (n = 15, 19.5%). CONCLUSIONS: Our findings indicate that LD requiring ICU admission is associated with more subsequent hospitalizations, a factor that could contribute to poorer future health for people with severe LD. In addition to chronic conditions prevalent in this study population, we found new diagnoses in the 5-year post-LD period including acute renal failure. With LD incidence increasing, more research is needed to understand conditions and factors that influence long term health after LD.

Clostridioidesdifficile infection rates from 7 facilities that used nucleic acid amplification testing (NAAT) alone for 12 months then switched to NAAT plus toxin enzyme immunoassay (EIA) and reported the latter result for 12 months were compared to 70 facilities that used NAAT alone for all 24 months. There was no significant difference in rates between facility groups over the first 12 months (P = .21, linear regression), but we detected a decrease in rates for the facilities that changed to NAAT+EIA (P < .0001).

OBJECTIVE: A guideline for the prevention of Clostridioides difficile infection (CDI) in 127 Veterans Health Administration acute-care facilities was implemented in July 2012. Beginning in 2015, a targeted assessment for prevention strategy was used to evaluate facilities for hospital-onset healthcare-facility-associated CDIs to focus prevention efforts where they might have the most impact in reaching a reduction goal of 30% nationwide. METHODS: We calculated standardized infection ratios (SIRs) and cumulative attributable differences (CADs) using a national data baseline. Facilities were ranked by CAD, and those with the 10 highest CAD values were targeted for periodic conference calls or a site visit from January 2016-September 2019. RESULTS: The hospital-onset healthcare-facility-associated CDI rate in the 10 facilities with the highest CADs declined 56% during the process improvement period, compared to a 44% decline in the 117 nonintervention facilities (P = .03). CONCLUSION: Process improvement interventions targeting facilities ranked by CAD values may be an efficient strategy for decreasing CDI rates in a large healthcare system.

OBJECTIVE: We examined Clostridioides difficile infection (CDI) prevention practices and their relationship with hospital-onset healthcare facility-associated CDI rates (CDI rates) in Veterans Affairs (VA) acute-care facilities. DESIGN: Cross-sectional study. METHODS: From January 2017 to February 2017, we conducted an electronic survey of CDI prevention practices and hospital characteristics in the VA. We linked survey data with CDI rate data for the period January 2015 to December 2016. We stratified facilities according to whether their overall CDI rate per 10,000 bed days of care was above or below the national VA mean CDI rate. We examined whether specific CDI prevention practices were associated with an increased risk of a CDI rate above the national VA mean CDI rate. RESULTS: All 126 facilities responded (100% response rate). Since implementing CDI prevention practices in July 2012, 60 of 123 facilities (49%) reported a decrease in CDI rates; 22 of 123 facilities (18%) reported an increase, and 41 of 123 (33%) reported no change. Facilities reporting an increase in the CDI rate (vs those reporting a decrease) after implementing prevention practices were 2.54 times more likely to have CDI rates that were above the national mean CDI rate. Whether a facility's CDI rates were above or below the national mean CDI rate was not associated with self-reported cleaning practices, duration of contact precautions, availability of private rooms, or certification of infection preventionists in infection prevention. CONCLUSIONS: We found considerable variation in CDI rates. We were unable to identify which particular CDI prevention practices (i.e., bundle components) were associated with lower CDI rates.

Nursing homes present a unique challenge for implementing infection prevention and control practices while striving to maintain a home-like environment. Medical devices such as urinary catheters and central venous catheters have become a part of nursing home care but can predispose residents to associated infections. Because evidence-based prevention bundles were implemented, catheter-associated urinary tract infections (CAUTIs) and central line-associated bloodstream infections (CLABSIs) were monitored in all U.S. Department of Veterans Affairs (VA) nursing homes, and outcomes were evaluated. Bundle components for CLABSIs focused on insertion technique, site selection, and routine assessment of central line necessity, while the CAUTI bundle focused on insertion technique, appropriate indication, and routine assessment of urinary catheter necessity. From October 2010 through September 2016, VA nursing homes reported nationwide reductions of CAUTIs (51.2%; P < .0001) and CLABSIs (25.0%; P = .0009).

Importance: Legionnaires disease (LD) incidence is increasing in the United States. Health care facilities are a high-risk setting for transmission of Legionella bacteria from building water systems to occupants. However, the contribution of LD in health care facilities to national LD rates is not well characterized. Objectives: To determine the burden of LD in US Department of Veterans Affairs (VA) patients and to assess the amount of LD with VA exposure. Design, Setting, and Participants: Retrospective cohort study of reported LD data in VA medical facilities in a national VA LD surveillance system from January 1, 2014, to December 31, 2016. The study population included total veteran enrollees and enrollees who used the VA health care system. Main Outcomes and Measures: The primary outcome was assessment of annual LD rates, categorized by VA and non-VA exposure. Legionnaires disease rates for cases with VA exposure were determined on both population and exposure potential levels. Rates by VA exposure potential were calculated using inpatient bed days of care, long-term care resident days, or outpatient encounters. In addition, types and amounts of LD diagnostic testing were calculated. Case and testing data were analyzed nationally and regionally. Results: There were 491 LD cases in the case report surveillance system from January 1, 2014, to December 31, 2016. Most cases (447 [91%]) had no VA exposure or only outpatient VA exposure. The remaining 44 cases had VA exposure from overnight stays. Total LD rates from January 1, 2014, to December 31, 2016, increased for all VA enrollees (from 1.5 to 2.0 per 100â¯000 enrollees; P = .04) and for users of VA health care (2.3 to 3.0 per 100â¯000 enrollees; P = .04). The LD rate for the subset who had no VA exposure also increased (0.90 to 1.47 per 100â¯000 enrollees; P < .001). In contrast, the LD rate for patients with VA overnight stay decreased on a population level (5.0 to 2.3 per 100â¯000 enrollees; P < .001) and an exposure level (0.31 to 0.15 per 100â¯000 enrollees; P < .001). Regionally, the eastern United States had the highest LD rates. The urine antigen test was the most used LD diagnostic method; 49â¯805 tests were performed in 2015-2016 with 335 positive results (0.67%). Conclusions and Relevance: Data in the VA LD databases showed an increase in overall LD rates over the 3 years, driven by increases in rates of non-VA LD. Inpatient VA-associated LD rates decreased, suggesting that the VA's LD prevention efforts have contributed to improved patient safety.

BACKGROUND: Declines in methicillin-resistant Staphylococcus aureus (MRSA) health care associated infections (HAIs) were previously reported in Veterans Affairs acute care (2012), spinal cord injury (SCIU) (2011), and long-term-care facilities (LTCFs) (2012). Here we report continuing declines in infection rates in these settings through September 2015. METHODS: Monthly data entered into a national database from 127 acute care facilities, 22 SCIUs, and 133 LTCFs were evaluated for trends using negative binomial regression. RESULTS: There were 23,153,240 intensive care unit (ICU) and non-ICU, and 1,794,234 SCIU patient-days from October 2007-September 2015, and 22,262,605 LTCF resident-days from July 2009-September 2015. Admission nasal swabbing remained >92% in all 3 venues. Admission prevalence changed from 13.2%-13.5% in acute care, from 35.1%-32.0% in SCIUs, and from 23.1%-25.0% in LTCFs during the analysis periods. Monthly HAI rates fell 87.0% in ICUs, 80.1% in non-ICUs, 80.9% in SCIUs, and 49.4% in LTCFs (all P values < .0001 for trend). During September 2015, there were 2 MRSA HAIs reported in ICUs, 20 (with 3 in SCIUs) in non-ICUs, and 31 in LTCFs nationwide. CONCLUSIONS: MRSA HAI rates declined significantly in acute care, SCIUs, and LTCFs over 8 years of the Veterans Affairs MRSA Prevention Initiative.

OBJECTIVE To detail the activities of the Veterans Health Administration (VHA) Antimicrobial Stewardship Initiative and evaluate outcomes of the program. DESIGN Observational analysis. SETTING The VHA is a large integrated healthcare system serving approximately 6 million individuals annually at more than 140 medical facilities. METHODS Utilization of nationally developed resources, proportional distribution of antibiotics, changes in stewardship practices and patient safety measures were reported. In addition, inpatient antimicrobial use was evaluated before and after implementation of national stewardship activities. RESULTS Nationally developed stewardship resources were well utilized, and many stewardship practices significantly increased, including development of written stewardship policies at 92% of facilities by 2015 (P<.05). While the proportional distribution of antibiotics did not change, inpatient antibiotic use significantly decreased after VHA Antimicrobial Stewardship Initiative activities began (P<.0001). A 12% decrease in antibiotic use was noted overall. The VHA has also noted significantly declining use of antimicrobials prescribed for resistant Gram-negative organisms, including carbapenems, as well as declining hospital readmission and mortality rates. Concurrently, the VHA reported decreasing rates of Clostridium difficile infection. CONCLUSIONS The VHA National Antimicrobial Stewardship Initiative includes continuing education, disease-specific guidelines, and development of example policies in addition to other highly utilized resources. While no specific ideal level of antimicrobial utilization has been established, the VHA has shown that improving antimicrobial usage in a large healthcare system may be achieved through national guidance and resources with local implementation of antimicrobial stewardship programs.

OBJECTIVE: A nationwide initiative was implemented in February 2014 to decrease Clostridium difficile infections (CDI) in Veterans Affairs (VA) long-term care facilities. We report a baseline of national CDI data collected during the 2 years before the Initiative. METHODS: Personnel at each of 122 reporting sites entered monthly retrospective CDI case data from February 2012 through January 2014 into a national database using case definitions similar to those used in the National Healthcare Safety Network Multidrug-Resistant Organism/CDI module. The data were evaluated using Poisson regression models to examine infection occurrences over time while accounting for admission prevalence and type of diagnostic test. RESULTS: During the 24-month analysis period, there were 100,800 admissions, 6,976,121 resident days, and 1,558 CDI cases. The pooled CDI admission prevalence rate (including recurrent cases) was 0.38 per 100 admissions, and the pooled nonduplicate/nonrecurrent community-onset rate was 0.17 per 100 admissions. The pooled long-term care facility-onset rate and the clinically confirmed (ie, diarrhea or evidence of pseudomembranous colitis) long-term care facility-onset rate were 1.98 and 1.78 per 10,000 resident days, respectively. Accounting for diagnostic test type, the long-term care facility-onset rate declined significantly (P=.05), but the clinically confirmed long-term care facility-onset rate did not. CONCLUSIONS: VA long-term care facility CDI rates were comparable to those in recent reports from other long-term care facilities. The significant decline in the long-term care facility-onset rate but not in the clinically confirmed long-term care facility-onset rate may have been due to less testing of asymptomatic patients. Efforts to decrease CDI rates in long-term care facilities are necessary as part of a coordinated approach to decrease healthcare-associated infections.

OBJECTIVE: An initiative was implemented in July 2012 to decrease Clostridium difficile infections (CDIs) in Veterans Affairs (VA) acute care medical centers nationwide. This is a report of national baseline CDI data collected from the 21 months before implementation of the initiative. METHODS: Personnel at each of 132 data-reporting sites entered monthly retrospective CDI case data from October 2010 through June 2012 into a central database using case definitions similar to those of the National Healthcare Safety Network multidrug-resistant organism/CDI module. RESULTS: There were 958,387 hospital admissions, 5,286,841 patient-days, and 9,642 CDI cases reported during the 21-month analysis period. The pooled CDI admission prevalence rate (including recurrent cases) was 0.66 cases per 100 admissions. The nonduplicate/nonrecurrent community-onset not-healthcare-facility-associated (CO-notHCFA) case rate was 0.35 cases per 100 admissions, and the community-onset healthcare facility-associated (CO-HCFA) case rate was 0.14 cases per 100 admissions. Hospital-onset healthcare facility-associated (HO-HCFA), clinically confirmed HO-HCFA (CC-HO-HCFA), and CO-HCFA rates were 9.32, 8.40, and 2.56 cases per 10,000 patient-days, respectively. There were significant decreases in admission prevalence (P = .0006, Poisson regression), HO-HCFA (P = .003), and CC-HO-HCFA (P = .004) rates after adjusting for type of diagnostic test. CO-HCFA and CO-notHCFA rates per 100 admissions also trended downward (P = .07 and .10, respectively). CONCLUSIONS: VA acute care medical facility CDI rates were higher than those reported in other healthcare systems, but unlike rates in other venues, they were decreasing or trending downward. Despite these downward trends, there is still a substantial burden of CDI in the system supporting the need for efforts to decrease rates further.
