Active surveillance and contact precautions for preventing MRSA 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 Health Administration (VA) facilities from 2007 to 2019 using active surveillance for facility admissions and contact precautions for patients colonized (CPC) or infected (CPI) with MRSA, but the value of these interventions is controversial. Objective: To determine the impact of active surveillance, CPC, and CPI on prevention MRSA HAIs, we conducted a prospective cohort study between July 2020 and June 2022 in all 123 acute-care VA medical facilities. In April 2020, all facilities were given the option to suspend any combination of active surveillance, CPC, or CPI to free up laboratory resources for COVID-19 testing and conserve personal protective equipment. We measured MRSA HAIs (cases per 1,000 patient days) in intensive care units (ICUs) and non-ICUs by the infection control policy. Results: During the analysis period, there were 917,591 admissions, 5,225,174 patient days, and 568 MRSA HAIs. Only 20% of facilities continued all 3 MRSA infection control measures in July 2020, but this rate increased to 57% by June 2022. The MRSA HAI rate for all infection sites in non-ICUs was 0.07 (95% CI, 0.05–0.08) for facilities practicing active surveillance plus CPC plus CPI compared to 0.12 (95% CI, 0.08–0.19; P = .01) for those not practicing any of these strategies, and in ICUs the MRSA HAI rates were 0.20 (95% CI, 0.15–0.26) and 0.65 (95% CI, 0.41–0.98; P < .001) for the respective policies. Similar differences were seen when the analyses were restricted to MRSA bloodstream HAIs. Accounting for monthly COVID-19 admissions to facilities over the analysis period using a negative binomial regression model did not change the relationships between facility policy and MRSA HAI rates in the ICUs or non-ICUs. There was no statistically significant difference in monthly facility urinary catheter-associated infection rates, a nonequivalent dependent variable, in the categories during the analysis period in either ICUs or non-ICUs. Conclusions: In Veterans Affairs medical centers, there were fewer MRSA HAIs when facilities practiced active surveillance and contact precautions for colonized or infected patients during the COVID-19 pandemic. The effect was greater in ICUs than non-ICUs.Disclosures: None

Veterans Health Administration National TeleOncology Service.

As the largest integrated health care system in the United States, the Veterans Health Administration (VA) is a leader in telehealth-delivered care. All 10 million Veterans cared for within the VA are eligible for telehealth. The VA cares for approximately 46,000 Veteran patients with newly diagnosed cancer and an estimated 400,000 prevalent cases annually. With nearly 38% of VA health care system users residing in rural areas and only 44% of rural counties having an oncologist, many Veterans lack local access to specialized cancer services. We describe the VA's National TeleOncology (NTO) Service. NTO was established to provide Veterans with the opportunity for specialized treatment regardless of geographical location. Designed as a hub-and-spoke model, VA oncologists from across the country can provide care to patients at spoke sites. Spoke sites are smaller and rural VA medical centers that are less able to independently provide the full range of services available at larger facilities. In addition to smaller rural spoke sites, NTO also provides subspecialized oncology care to Veterans located in larger VA medical facilities that do not have subspecialties available or that have limited capacity. As of fiscal year 2021, 23 clinics are served by or engaged in planning for delivery of NTO and there are 24 physicians providing care through the NTO virtual hub. Most NTO physicians continue to provide patient care in separate traditional in-person clinics. Approximately 4,300 unique Veterans have used NTO services. Approximately half (52%) of Veterans using NTO lived in rural areas. Most of these Veterans had more than one remote visit through NTO. NTO is a state-of-the-art model that has the potential to revolutionize the way cancer care is delivered, which should improve the experience of Veterans receiving cancer care.

Trends in COVID-19 cases and clinical management in Veterans Health Administration medical facilities: A national cohort study.

ObjectiveWe explored longitudinal trends in sociodemographic characteristics, reported symptoms, laboratory findings, pharmacological and non-pharmacological treatment, comorbidities, and 30-day in-hospital mortality among hospitalized patients with coronavirus disease 2019 (COVID-19).MethodsThis retrospective cohort study included patients diagnosed with COVID-19 in the United States Veterans Health Administration between 03/01/20 and 08/31/20 and followed until 09/30/20. We focused our analysis on patients that were subsequently hospitalized, and categorized them into groups based on the month of hospitalization. We summarized our findings through descriptive statistics. We used Cuzick’s Trend Test to examine any differences in the distribution of our study variables across the six months.ResultsDuring our study period, we identified 43,267 patients with COVID-19. A total of 8,240 patients were hospitalized, and 13.1% (N = 1,081) died within 30 days of admission. Hospitalizations increased over time, but the proportion of patients that died consistently declined from 24.8% (N = 221/890) in March to 8.0% (N = 111/1,396) in August. Patients hospitalized in March compared to August were younger on average, mostly black, urban-dwelling, febrile and dyspneic. They also had a higher frequency of baseline comorbidities, including hypertension and diabetes, and were more likely to present with abnormal laboratory findings including low lymphocyte counts and elevated creatinine. Lastly, there was a decline from March to August in receipt of mechanical ventilation (31.4% to 13.1%) and hydroxychloroquine (55.3% to <1.0%), while treatment with dexamethasone (3.7% to 52.4%) and remdesivir (1.1% to 38.9%) increased.ConclusionAmong hospitalized patients with COVID-19, we observed a trend towards decreased disease severity and mortality over time.

The Focus They Deserve: Improving Women Veterans' Health Care Access.

Veterans Health Administration (VHA) initiatives aim to provide veterans timely access to quality health care. The focus of this analysis was provider and staff perspectives on women veterans' access in the context of national efforts to improve veterans' access to care. We completed 21 site visits at Veterans Health Administration medical facilities to evaluate the implementation of a national access initiative. Qualitative data collection included semistructured interviews (n=127), focus groups (n=81), and observations with local leadership, administrators, providers, and support staff across primary and specialty care services at each facility. Deductive and inductive content analysis was used to identify barriers, facilitators, and contextual factors affecting implementation of initiatives and women veterans' access. Participants identified barriers to women veterans' access and strategies used to improve access. Barriers included a limited availability of providers trained in women's health and gender-specific care services (e.g., women's specialty care), inefficient referral and coordination with community providers, and psychosocial factors (e.g., childcare). Participants also identified issues related to childcare and perceived harassment in medical facility settings as distinct access issues for women veterans. Strategies focused on increasing internal capacity to provide on-site women's comprehensive care and specialty services by streamlining provider training and credentialing, contracting providers, using telehealth, and improving access to community providers to fill gaps in women's services. Participants also highlighted efforts to improve gender-sensitive care delivery. Although some issues affect all veterans, problems with community care referrals may disproportionately affect women veterans' access owing to a necessary reliance on community care for a range of gender-specific services.

Building/Campus Characteristics and Legionella in Potable Water Systems at Veterans Health Administration Facilities

Background: When control mechanisms such as water temperature and biocide level are insufficient, Legionella, the causative bacteria of Legionnaires’ disease, can proliferate in water distribution systems in buildings. Guidance and oversight bodies are increasingly prioritizing water safety programs in healthcare facilities to limit Legionella growth. However, ensuring optimal implementation in large buildings is challenging. Much is unknown, and sometimes assumed, about whether building and campus characteristics influence Legionella growth. We used an extensive real-world environmental Legionella data set in the Veterans Health Administration (VHA) healthcare system to examine infrastructure characteristics and Legionella positivity. Methods: VHA medical facilities across the country perform quarterly potable water sampling of healthcare buildings for Legionella detection as part of a comprehensive water safety program. Results are reported to a standardized national database. We did an exploratory univariate analysis of facility-reported Legionella data from routine potable water samples taken in 2015 to 2018, in conjunction with infrastructure characteristics available in a separate national data set. This review examined the following characteristics: building height (number of floors), building age (reported construction year), and campus acreage. Results: The final data set included 201,936 water samples from 819 buildings. Buildings with 1–5 floors (n = 634) had a Legionella positivity rate of 5.3%, 6–10 floors (n = 104) had a rate of 6.4%, 11–15 floors (n = 36) had a rate of 8.1%, and 16–22 floors (n = 9) had a rate of 8.8%. All rates were significantly different from each other except 11–15 floors and 16–22 floors (P &lt; .05, χ2). The oldest buildings (1800s) had significantly less (P &lt; .05, χ2) Legionella positivity than those built between 1900 and 1939 and between 1940 and 1979, but they were no different than the newest buildings (Fig. 1). In newer buildings (1980–2019), all decades had buildings with Legionella positivity (Fig. 1 inset). Campus acreage varied from ~3 acres to almost 500 acres. Although significant differences were found in Legionella positivity for different campus sizes, there was no clear trend and campus acreage may not be a suitable proxy for the extent or complexity of water systems feeding buildings. Conclusions: The analysis of this large, real-world data set supports an assumption that taller buildings are more likely to be associated with Legionella detection, perhaps a result of more extensive piping. In contrast, the assumption that newer buildings are less associated with Legionella was not fully supported. These results demonstrate the variability in Legionella positivity in buildings, and they also provide evidence that can inform implementation of water safety programs.Funding: NoneDisclosures: Chetan Jinadatha, principal Investigator/Co-I: Research: NIH/NINR, AHRQ, NSF principal investigator: Research: Xenex Healthcare Services.

Does Offering Battlefield Acupuncture Lead to Subsequent Use of Traditional Acupuncture?

Objectives:Veterans Health Administration encourages auricular acupuncture (Battlefield Acupuncture/BFA) as a nonpharmacologic approach to pain management. Qualitative reports highlighted a “gateway hypothesis”: providing BFA can lead to additional nonpharmacologic treatments. This analysis examines subsequent use of traditional acupuncture.Research Design:Cohort study of Veterans treated with BFA and a propensity score matched comparison group with a 3-month follow-up period to identify subsequent use of traditional acupuncture. Matching variables included pain, comorbidity, and demographics, with further adjustment in multivariate regression analysis.Subjects:We identified 41,234 patients who used BFA across 130 Veterans Health Administration medical facilities between October 1, 2016 and March 31, 2019. These patients were matched 2:1 on Veterans who used VA care but not BFA during the same period resulting in a population of 24,037 BFA users and a comparison cohort of 40,358 non-BFA users. Patients with prior use of traditional acupuncture were excluded.Results:Among Veterans receiving BFA, 9.5% subsequently used traditional acupuncture compared with 0.9% of non-BFA users (P<0.001). In adjusted analysis, accounting for patient characteristics and regional availability of traditional acupuncture, patients who used BFA had 10.9 times greater odds (95% confidence interval, 8.67–12.24) of subsequent traditional acupuncture use.Conclusions:Providing BFA, which is easy to administer during a patient visit and does not require providers be formally certified, led to a substantial increase in use of traditional acupuncture. These findings suggest that the value of offering BFA may not only be its immediate potential for pain relief but also subsequent engagement in additional therapies.

Staff perceptions implementing interprofessional team-based behavioural healthcare

ABSTRACTThe US Veterans Health Administration (VHA) in 2013 mandated a nationwide implementation of interprofessional team-based care in the general mental health setting and officially endorsed the collaborative care model in 2015 to guide the coordinated and anticipatory care to be delivered by these teams. Front-line clinic staff are major stakeholders whose practices are most directly affected by this implementation and may or may not view teams as useful or feasible for their practice. Our objective was to examine their perspectives on delivering team-to-patient care in order to understand what system-level efforts can best support the transition to such care from the more conventional provider-to-patient care. We conducted 14 semi-structured interviews with staff from general mental health clinics across three different VHA medical facilities. The interview questions focused on asking how care is organised and delivered at their clinic, their experiences in collaborating with other staff, and how the clinic handles changes. Four recurrent themes were identified: navigating workplace supervision, organisation, and role structures; continuing professional growth and relationships; delivering patient-focused care through education and connection to resources; and utilising information technology for communication and panel-based management. Quality improvement efforts were rarely discussed during the interviews. Our results indicate that staff’s endorsement of the implementation of interprofessional care teams in general mental health settings may be strengthened through associated efforts targeted at enhancing their experiences aligned to these emergent themes.

Extracting Sexual Trauma Mentions from Electronic Medical Notes Using Natural Language Processing.

Patient history of sexual trauma is of clinical relevance to healthcare providers as survivors face adverse health-related outcomes. This paper describes a method for identifying mentions of sexual trauma within the free text of electronic medical notes. A natural language processing pipeline for information extraction was developed and scaled to handle a large corpus of electronic medical notes used for this study from US Veterans Health Administration medical facilities. The tool was used to identify sexual trauma mentions and create snippets around every asserted mention based on a domain-specific lexicon developed for this purpose. All snippets were evaluated by trained human reviewers. An overall positive predictive value (PPV) of 0.90 for identifying sexual trauma mentions from the free text and a PPV of 0.71 at the patient level are reported. The metrics are superior for records from female patients.

Process mapping appointments to identify improvements in care delivered to patients who screen positive for depression

Rationale, aims and objectives After screening positive for depression, many patients do not receive effective medication or maintain optimal contact with practitioners. Our objective was to examine how appointments that patients have after screening positive may affect the delivery of evidence-based and guideline-concordant depression care. Methods We reviewed treatment records for 271 patients who screened positive for depression in primary care across three United States Veterans Health Administration medical facilities. For each patient, we mapped the process of appointments that took place following the positive screen, noting the number of appointments, the service line in which each appointment was held, as well as whether guideline-concordant depression care was in turn received over four months. Results We found that (i) approximately half of the patients who screened positive had no follow-up appointments, (ii) all patients who had two or more follow-up appointments received some – but not necessarily guideline-concordant – mental health treatment, and (iii) there were distinct patterns across the three facilities regarding which service lines’ appointments most often resulted in treatment. Conclusions Our work offers a novel approach of using data on appointments that patients have after screening positive for depression to shed light on current care practices. The number of post-screening appointments can be an informative process measure for improving depression care to become more guideline-concordant. Facilities vary substantially in terms of which service lines they use to attain guideline-concordance, likely due to notable differences in how their primary care, integrated primary care behavioral health, and mental health services are organized.

Cardiovascular Disease Risk Factors Among Women Veterans at VA Medical Facilities

ABSTRACTBACKGROUNDHypertension, hyperlipidemia, diabetes, and obesity in middle adulthood each elevate the long-term risk of cardiovascular disease (CVD). The prevalence of these conditions among women veterans is incompletely described.OBJECTIVETo describe the prevalence of CVD risk factors among women veterans in middle adulthood.DESIGNSerial cross-sectional studies of data from the Diabetes Epidemiologic Cohorts (DEpiC), a national, longitudinal data set including information on all patients in the Veterans Health Administration (VA).PARTICIPANTSWomen veterans (n = 255,891) and men veterans (n = 2,271,605) aged 35–64 receiving VA care in fiscal year (FY) 2010.MAIN MEASURESPrevalence of CVD risk factors in FY2010 by age and, for those aged 45–54 years, by race, region, period of military service, priority status, and mental illness or substance abuse; prevalence by year from 2000 to 2010 in women veterans receiving VA care in both 2000 and 2010 who were free of the factor in 2000.KEY RESULTSHypertension, hyperlipidemia, and diabetes were common among women and men, although more so among men. Hypertension was present in 13 % of women aged 35–44 years, 28 % of women aged 45–54, and 42 % of women aged 55–64. Hyperlipidemia prevalence was similar. Diabetes affected 4 % of women aged 35–44, and increased more than four-fold in prevalence to 18 % by age 55–64. The prevalence of obesity increased from 14 % to 18 % with age among women and was similarly prevalent in men. The relative rate of having two or more CVD risk factors in women compared to men increased progressively with age, from 0.55 (35–44 years) to 0.71 (45–54) to 0.73 (55–64). Most of the women with a factor present in 2010 were first diagnosed with the condition in the 10 years between 2000 and 2010.CONCLUSIONSCVD risk factors are common among women veterans aged 35–64. Future research should investigate which interventions would most effectively reduce risk in this population.Electronic supplementary materialThe online version of this article (doi:10.1007/s11606-013-2381-9) contains supplementary material, which is available to authorized users.

The Prevalence of Overweight and Obesity in Veterans with Multiple Sclerosis

To estimate the prevalence and factors associated with overweight and obesity in veterans with multiple sclerosis (MS) enrolled in the Veterans Health Administration (VA) and to compare the prevalence in this group with gender-specific published rates for the general population of veterans receiving outpatient care at VA medical facilities. Cross-sectional cohort study linking electronic medical record information to mailed survey from 1999 to 2004. A total of 4703 veterans with MS enrolled in VA who returned questionnaires as part of two cross-sectional studies. Main outcome measures included body mass index, demographic information, Veteran RAND 36-item Health Survey, frequency of physical exercise, and other health conditions. Overall, 28% of female and 42.8% of male veterans with MS were overweight. Another 25% of women and 21.2% of male veterans met the criteria for obesity. Compared with a historical cohort of veterans enrolled in the VA, veterans with MS had a slightly higher adjusted prevalence of overweight than did veterans in general (42.3% vs. 39.6%, respectively) but a lower adjusted prevalence of obesity (20.1% vs. 33.1%). In adjusted logistic regression, age, smoking, and lower levels of pain were associated with a lower likelihood of overweight or obesity. Being male, married, employed and having arthritis and diabetes were associated with a greater likelihood of overweight or obesity. Overweight and obesity are a problem for more than 60% of veterans with MS in the VA. Screening for overweight and obesity should be done routinely. Interventions to prevent and manage excessive weight in individuals with MS should be developed and evaluated.
