Variations in antihypertensive medication treatment and blood pressure control among Veterans with HIV and existing hypertension.

BACKGROUND: Hypertension is a leading risk factor for cardiovascular disease among patients living with HIV (PLWH). Understanding the predictors and patterns of antihypertensive medication prescription and blood pressure (BP) control among PLWH with hypertension (HTN) is important to improve the primary prevention efforts for this high-risk population. We sought to assess important patient-level correlates (eg, race) and inter-facility variations in antihypertension medication prescriptions and BP control among Veterans living with HIV (VLWH) and HTN. METHODS: We studied VLWH with a diagnosis of HTN who received care in the Veterans Health Administration (VHA) from January 2018 to December 2019. We evaluated HTN treatment and blood pressure control across demographic variables, including race, and by medical comorbidities. Data were also compared among VHA facilities. Predictors of HTN treatment and control were assessed in 2-level hierarchical multivariate logistic regression models to estimate odds ratios (ORs). The VHA facility random-effects parameters from the hierarchical models were used to calculate the median odds ratios to characterize the variation across the different VHA facilities. RESULTS: A total of 17,468 VLWH with HTN (mean age 61 years, 97% male, 54% Black, 40% White) who received care within the VHA facilities in 2018-2019 were included. 73% were prescribed antihypertension medications with higher prescription rates among Black vs White patients (75% vs 71%) and higher prescription rates among patients with a history of cardiovascular disease, diabetes, and kidney disease (>80%), and those receiving antiretroviral therapy and with controlled HIV viral load (∼75%). Only 27% of VLWH with HTN had optimal BP control of systolic BP <130 mmHg and diastolic BP <80 mmHg, with a lower rate of control among Black vs White patients (24% v. 31%). In multivariate regression, Black patients had a higher likelihood of HTN medication prescription (OR 1.32, 95% CI: 1.22-1.42) but were less likely to have optimal BP control (OR 0.82; 0.76-0.88). Important positive correlates of antihypertensive prescription and optimal BP control included: number of outpatient visits in prior year, and histories of diabetes, coronary artery disease, and heart failure. There was about 10% variability in both antihypertensive prescription and BP control patterns between VHA facilities for patients with similar characteristics. There was increased inter-facility variation in antihypertensive prescription among those with a history of heart failure and those not receiving antiretroviral therapy. CONCLUSION: In a retrospective analysis of large VHA data, we found that VLWH with HTN have suboptimal antihypertensive medication prescription and BP control. Black VLWH had higher HTN medication prescription rates but lower optimal BP control.

Using Structured Observations to Evaluate the Effects of a Personalized Music Intervention on Agitated Behaviors and Mood in Nursing Home Residents With Dementia: Results From an Embedded, Pragmatic Randomized Controlled Trial.

OBJECTIVE: The objective of this research was to determine if a personalized music intervention reduced the frequency of agitated behaviors as measured by structured observations of nursing home (NH) residents with dementia. DESIGN: The design was a parallel, cluster-randomized, controlled trial. SETTING: The setting was 54 NH (27 intervention, 27 control) from four geographically-diverse, multifacility NH corporations. PARTICIPANTS: The participants were 976 NH residents (483 intervention, 493 control) with Alzheimer's disease or related dementias (66% with moderate to severe symptoms); average age 80.3 years (SD: 12.3) and 25.1% were Black. INTERVENTION: The intervention was individuals' preferred music delivered via a personalized music device. MEASUREMENT: The measurement tool was the Agitated Behavior Mapping Instrument, which captures the frequency of 13 agitated behaviors and five mood states during 3-minute observations. RESULTS: The results show that no verbally agitated behaviors were reported in a higher proportion of observations among residents in NHs randomized to receive the intervention compared to similar residents in NHs randomized to usual care (marginal interaction effect (MIE): 0.061, 95% CI: 0.028-0.061). Residents in NHs randomized to receive the intervention were also more likely to be observed experiencing pleasure compared to residents in usual care NHs (MIE: 0.038; 95% CI: 0.008-0.073)). There was no significant effect of the intervention on physically agitated behaviors, anger, fear, alertness, or sadness. CONCLUSIONS: The conclusions are that personalized music may be effective at reducing verbally-agitated behaviors. Using structured observations to measure behaviors may avoid biases of staff-reported measures.

Utility of cerebrovascular imaging biomarkers to detect cerebral amyloidosis.

INTRODUCTION: The relationship between cerebrovascular disease (CVD) and amyloid beta (Aß) in Alzheimer's disease (AD) is understudied. We hypothesized that magnetic resonance imaging (MRI)-based CVD biomarkers-including cerebral microbleeds (CMBs), lacunar infarction, and white matter hyperintensities (WMHs)-would correlate with Aß positivity on positron emission tomography (Aß-PET). METHODS: We cross-sectionally analyzed data from the Alzheimer's Disease Neuroimaging Initiative (ADNI, N = 1352). Logistic regression was used to calculate odds ratios (ORs), with Aß-PET positivity as the standard-of-truth. RESULTS: Following adjustment, WMHs (OR = 1.25) and superficial CMBs (OR = 1.45) remained positively associated with Aß-PET positivity (p < 0.001). Deep CMBs and lacunes exhibited a varied relationship with Aß-PET in cognitive subgroups. The combined diagnostic model, which included CVD biomarkers and other accessible measures, significantly predicted Aß-PET (pseudo-R2 = 0.41). DISCUSSION: The study highlights the translational value of CVD biomarkers in diagnosing AD, and underscores the need for more research on their inclusion in diagnostic criteria. CLINICALTRIALS: gov: ADNI-2 (NCT01231971), ADNI-3 (NCT02854033). HIGHLIGHTS: Cerebrovascular biomarkers linked to amyloid beta (Aß) in Alzheimer's disease (AD). White matter hyperintensities and cerebral microbleeds reliably predict Aß-PET positivity. Relationships with Aß-PET vary by cognitive stage. Novel accessible model predicts Aß-PET status. Study supports multimodal diagnostic approaches.

Detection of delirium in older patients-A point prevalence study in surgical and non-surgical hospital wards.

AIMS AND OBJECTIVES: To (i) determine the prevalence of delirium and identify delirium subtypes in surgical and non-surgical patients aged ≥65 years, (ii) determine whether certain precipitating factors affect the prevalence of delirium and (iii) review patients' medical records for description of delirium symptoms and the presence of International Classification of Diseases (ICD-10) coding for delirium in discharge summaries. METHODOLOGICAL DESIGN AND JUSTIFICATIONS: Despite being a robust predictor of morbidity and mortality in older adults, delirium might be inadequately recognised and under-reported in patients' medical records and discharge summaries. A point prevalence study (24-h) of patients ≥65 years from surgical and non-surgical wards was therefore conducted in a tertiary university hospital. ETHICAL ISSUES AND APPROVAL: The study was approved by the Data Protection Officer at the university hospital (2018/3454). RESEARCH METHODS, INSTRUMENTS AND/OR INTERVENTIONS: Patients were assessed for delirium with 4AT and delirium subtypes with the Delirium Motor Subtype Scale. Information about room transfers, need and use of sensory aids and medical equipment was collected onsite. Patients' medical records were reviewed for description of delirium symptoms and of ICD-10 codes. RESULTS: Overall, 123 patients were screened (52% female). Delirium was identified in 27% of them. Prevalence was associated with advanced age (≥85 years). The uncharacterised delirium subtype was most common (36%), followed by hypoactive (30%), hyperactive (24%) and mixed (9%). There were significant associations between positive screening tests and the need and use of sensory aids. Delirium symptoms were described in 58% of the patients who tested positive for delirium and the ICD-10 code for delirium was registered in 12% of these patients' discharge summaries. CONCLUSIONS: The high prevalence of delirium and limited use of discharge codes highlight the need to improve the identification of delirium in hospital settings and at discharge. Increased awareness and detection of delirium in hospital settings are vital to improve patient care.

Trends and geographic differences in social work telehealth utilization.

We plotted trends in social work telehealth use among Veterans in a U.S. national social work staffing program and examined the relationship between geographic factors (rurality and neighborhood disadvantage) and telehealth use (audio and video) using linear probability models. Social work telehealth use increased among Veterans during the COVID-19 pandemic. There were no geographic differences in telephone telehealth use. Video telehealth use was less common among Veterans in isolated rural areas and among Veterans in highly disadvantaged areas. Outreach efforts can address barriers that Veterans who live in rural and disadvantaged areas may experience in using video telehealth.

Prevalence of Comorbid Depression and Insomnia Among Veterans Hospitalized for Heart Failure with Alzheimer Disease and Related Disorders.

OBJECTIVE: To examine prevalence of Alzheimer Disease and related dementias (ADRD) and patient characteristics as a function of comorbid insomnia and/or depression among heart failure (HF) patients discharged from hospitals. DESIGN: Retrospective cohort descriptive epidemiology study. SETTING: VA Hospitals. PARTICIPANTS: N = 373,897 Veterans hospitalized with heart failure from October 1, 2011 until September 30, 2020. MEASUREMENTS: We examined VA and Center for Medicare & Medicaid Services (CMS) coding in the year prior to admission using published ICD-9/10 codes for dementia, insomnia, and depression. The primary outcome was the prevalence of ADRD and the secondary outcomes were 30-day and 365-day mortality. RESULTS: The cohort were predominantly older adults (mean age = 72 years, SD = 11), male (97%), and White (73%). Dementia prevalence in participants without insomnia or depression was 12%. In those with both insomnia and depression, dementia prevalence was 34%. For insomnia alone and depression alone, dementia prevalence was 21% and 24%, respectively. Mortality followed a similar pattern with highest 30-day and 365-day mortality higher in those with both insomnia and depression. CONCLUSIONS: These results suggest that persons with both insomnia and depression are at an increased risk of ADRD and mortality compared to persons with one or neither condition. Screening for both insomnia and depression, especially in patients with other ADRD risk factors, could lead to earlier identification of ADRD. Understanding comorbid conditions which may represent earlier signs of ADRD may be critical in the identification of ADRD risk.

Physical Function Assessment of Older Veterans With Serious Mental Illness.

OBJECTIVE: To characterize the physical function of older veterans with serious mental illness (SMI) across endurance, strength, and mobility domains. DESIGN: Retrospective analysis of clinical performance data. SETTING: Gerofit program, a national outpatient supervised exercise program for older veterans, delivered in Veterans Health Administration sites. PARTICIPANTS: Older veterans aged 60 and older (n = 166 with SMI, n = 1,441 without SMI) enrolled across eight national Gerofit sites between 2010 and 2019. MEASUREMENTS: Performance measures of physical function covering endurance (6-minute walk test), strength (chair stands, arm curls), and mobility (10-m walk, 8-foot-up-and-go), were administered at Gerofit enrollment. Baseline data from these measures were analyzed to characterize the functional profiles of older veterans with SMI. One sample t tests were examined to compare functional performance of older veterans with SMI to age- and sex-based reference scores. Propensity score matching (1:3) and linear mixed effects models were used to evaluate differences in function between veterans with and without SMI. RESULTS: Older veterans with SMI performed worse on all measures of function (chair stands, arm curls, 10-m walk, 6-minute walk test, 8-foot-up-and-go) compared to age- and sex-based reference scores with statistically significant differences present in the male sample. Functional performance of those with SMI was also worse compared to propensity-score matched older veterans without SMI with statistically significant differences on chair stands, 6-minute walk test, and 10-m walk. CONCLUSION: Older veterans with SMI have compromised strength, mobility, and endurance. Physical function should be a core component of screening and treatment for this population.

Impact of Delirium on Outcomes After Intracerebral Hemorrhage.

BACKGROUND AND PURPOSE: Delirium portends worse outcomes after intracerebral hemorrhage (ICH), but it is unclear if symptom resolution or postacute care intensity may mitigate its impact. We aimed to explore differences in outcome associated with delirium resolution before hospital discharge, as well as the potential mediating role of postacute discharge site. METHODS: We performed a single-center cohort study on consecutive ICH patients over 2 years. Delirium was diagnosed according to DSM-5 criteria and further classified as persistent or resolved based on delirium status at hospital discharge. We determined the impact of delirium on unfavorable 3-month outcome (modified Rankin Scale score, 4-6) using logistic regression models adjusted for established ICH predictors, then used mediation analysis to examine the indirect effect of delirium via postacute discharge site. RESULTS: Of 590 patients (mean age 70.5±15.5 years, 52% male, 83% White), 59% (n=348) developed delirium during hospitalization. Older age and higher ICH severity were delirium risk factors, but only younger age predicted delirium resolution, which occurred in 75% (161/215) of ICH survivors who had delirium. Delirium was strongly associated with unfavorable outcome, but patients with persistent delirium fared worse (adjusted odds ratio [OR], 7.3 [95% CI, 3.3-16.3]) than those whose delirium resolved (adjusted OR, 3.1 [95% CI, 1.8-5.5]). Patients with delirium were less likely to be discharged to inpatient rehabilitation than skilled nursing facilities (adjusted OR, 0.31 [95% CI, 0.17-0.59]), and postacute care site partially mediated the relationship between delirium and functional outcome in ICH survivors, leading to a 25% reduction in the effect of delirium (without mediator: adjusted OR, 3.0 [95% CI, 1.7-5.6]; with mediator: adjusted OR, 2.3 [95% CI, 1.2-4.3]). CONCLUSIONS: Acute delirium resolves in most patients with ICH by hospital discharge, which was associated with better outcomes than in patients with persistent delirium. The impact of delirium on outcomes may be further mitigated by postacute rehabilitation.

Variation in statin prescription among veterans with HIV and known atherosclerotic cardiovascular disease.

BACKGROUND: People with HIV have increased atherosclerotic cardiovascular disease (ASCVD) risk, worse outcomes following incident ASCVD, and experience gaps in cardiovascular care, highlighting the need to improve delivery of preventive therapies in this population. OBJECTIVE: Assess patient-level correlates and inter-facility variations in statin prescription among Veterans with HIV and known ASCVD. METHODS: We studied Veterans with HIV and existing ASCVD, ie, coronary artery disease (CAD), ischemic cerebrovascular disease (ICVD), and peripheral arterial disease (PAD), who received care across 130 VA medical centers for the years 2018-2019. We assessed correlates of statin prescription using two-level hierarchical multivariable logistic regression. Median odds ratios (MORs) were used to quantify inter-facility variation in statin prescription. RESULTS: Nine thousand six hundred eight Veterans with HIV and known ASCVD (mean age 64.3 ± 8.9 years, 97% male, 48% Black) were included. Only 68% of the participants were prescribed any-statin. Substantially higher statin prescription was observed for those with diabetes (adjusted odds ratio [OR] = 2.3, 95% confidence interval [CI], 2.0-2.6), history of coronary revascularization (OR = 4.0, CI, 3.2-5.0), and receiving antiretroviral therapy (OR = 3.0, CI, 2.7-3.4). Blacks (OR = 0.7, CI, 0.6-0.9), those with non-coronary ASCVD, ie, ICVD and/or PAD only, (OR 0.53, 95% CI: 0.48-0.57), and those with history of illicit substance use (OR=0.7, CI, 0.6-0.9) were less likely to be prescribed statins. There was significant variation in statin prescription across VA facilities (10th, 90th centile: 55%, 78%), with an estimated 20% higher likelihood of difference in statin prescription practice for two clinically similar individuals treated at two comparable facilities (adjusted MOR = 1.21, CI, 1.18-1.24), and a greater variation observed for Blacks or those with non-coronary ASCVD or history of illicit drug use. CONCLUSION: In an analysis of large-scale VA data, we found suboptimal statin prescription and significant interfacility variation in statin prescription among Veterans with HIV and known ASCVD, particularly among Blacks and those with a history of non-coronary ASCVD.

New Antipsychotic Prescribing Continued into Skilled Nursing Facilities Following a Heart Failure Hospitalization: a Retrospective Cohort Study.

BACKGROUND: Multimorbidity and polypharmacy are common among individuals hospitalized for heart failure (HF). Initiating high-risk medications such as antipsychotics may increase the risk of poor clinical outcomes, especially if these medications are continued unnecessarily into skilled nursing facilities (SNFs) after hospital discharge. OBJECTIVE: Examine how often older adults hospitalized with HF were initiated on antipsychotics and characteristics associated with antipsychotic continuation into SNFs after hospital discharge. DESIGN: Retrospective cohort. PARTICIPANTS: Veterans without prior outpatient antipsychotic use, who were hospitalized with HF between October 1, 2010, and September 30, 2015, and were subsequently discharged to a SNF. MAIN MEASURES: Demographics, clinical conditions, prior healthcare utilization, and antipsychotic use data were ascertained from Veterans Administration records, Minimum Data Set assessments, and Medicare claims. The outcome of interest was continuation of antipsychotics into SNFs after hospital discharge. KEY RESULTS: Among 18,008 Veterans, antipsychotics were newly prescribed for 1931 (10.7%) Veterans during the index hospitalization. Among new antipsychotic users, 415 (21.5%) continued antipsychotics in skilled nursing facilities after discharge. Dementia (adjusted OR (aOR) 1.48, 95% CI 1.11-1.98), psychosis (aOR 1.62, 95% CI 1.11-2.38), proportion of inpatient days with antipsychotic use (aOR 1.08, 95% CI 1.07-1.09, per 10% increase), inpatient use of only typical (aOR 0.47, 95% CI 0.30-0.72) or parenteral antipsychotics (aOR 0.39, 95% CI 0.20-0.78), and the day of hospital admission that antipsychotics were started (day 0-4 aOR 0.36, 95% CI 0.23-0.56; day 5-7 aOR 0.54, 95% CI 0.35-0.84 (reference: day > 7 of hospital admission)) were significant predictors of continuing antipsychotics into SNFs after hospital discharge. CONCLUSIONS: Antipsychotics are initiated fairly often during HF admissions and are commonly continued into SNFs after discharge. Hospital providers should review antipsychotic indications and doses throughout admission and communicate a clear plan to SNFs if antipsychotics are continued after discharge.

Effectiveness of a Second COVID-19 Vaccine Booster Dose Against Infection, Hospitalization, or Death Among Nursing Home Residents - 19 States, March 29-July 25, 2022.

Nursing home residents continue to experience significant COVID-19 morbidity and mortality (1). On March 29, 2022, the Advisory Committee on Immunization Practices (ACIP) recommended a second mRNA COVID-19 vaccine booster dose for adults aged ≥50 years and all immunocompromised persons who had received a first booster ≥4 months earlier.* On September 1, 2022, ACIP voted to recommend bivalent mRNA COVID-19 vaccine boosters for all persons aged ≥12 years who had completed the primary series using monovalent vaccines ≥2 months earlier (2). Data on COVID-19 booster dose vaccine effectiveness (VE) in the nursing home population are limited (3). For this analysis, academic, federal, and private partners evaluated routine care data collected from 196 U.S. community nursing homes to estimate VE of a second mRNA COVID-19 vaccine booster dose among nursing home residents who had received 3 previous COVID-19 vaccine doses (2 primary series doses and 1 booster dose). Residents who received second mRNA COVID-19 vaccine booster doses during March 29-June 15, 2022, with follow-up through July 25, 2022, were found to have 60-day VE of 25.8% against SARS-CoV-2 (the virus that causes COVID-19 infection), 73.9% against severe COVID-19 outcomes (a combined endpoint of COVID-19-associated hospitalizations or deaths), and 89.6% against COVID-19-associated deaths alone. During this period, subvariants BA.2 and BA.2.12.1 (March-June 2022), and BA.4 and BA.5 (July 2022) of the B.1.1.529 and BA.2 (Omicron) variant were predominant. These findings suggest that among nursing home residents, second mRNA COVID-19 vaccine booster doses provided additional protection over first booster doses against severe COVID-19 outcomes during a time of emerging Omicron variants. Facilities should continue to ensure that nursing home residents remain up to date with COVID-19 vaccination, including bivalent vaccine booster doses, to prevent severe COVID-19 outcomes.

Risk factors for Veteran food insecurity: findings from a National US Department of Veterans Affairs Food Insecurity Screener.

OBJECTIVE: Food insecurity is associated with numerous adverse health outcomes. The US Veterans Health Administration (VHA) began universal food insecurity screening in 2017. This study examined prevalence and correlates of food insecurity among Veterans screened. DESIGN: Retrospective cross-sectional study using VHA administrative data. Multivariable logistic regression models were estimated to identify sociodemographic and medical characteristics associated with a positive food insecurity screen. SETTING: All US Veterans Administration (VA) medical centres (n 161). PARTICIPANTS: All Veterans were screened for food insecurity since screening initiation (July 2017-December 2018). RESULTS: Of 3 304 702 Veterans screened for food insecurity, 44 298 were positive on their initial screen (1·3 % of men; 2·0 % of women). Food insecurity was associated with identifying as non-Hispanic Black or Hispanic. Veterans who were non-married/partnered, low-income Veterans without VA disability-related compensation and those with housing instability had higher odds of food insecurity, as did Veterans with a BMI < 18·5, diabetes, depression and post-traumatic stress disorder. Prior military sexual trauma (MST) was associated with food insecurity among both men and women. Women screening positive, however, were eight times more likely than men to have experienced MST (48·9 % v. 5·9 %). CONCLUSIONS: Food insecurity was associated with medical and trauma-related comorbidities as well as unmet social needs including housing instability. Additionally, Veterans of colour and women were at higher risk for food insecurity. Findings can inform development of tailored interventions to address food insecurity such as more frequent screening among high-risk populations, onsite support applying for federal food assistance programs and formal partnerships with community-based resources.

The effect of age on fever response among nursing home residents with SARS-COV-2 infection.

Over 15,000 veterans in 135 VA nursing homes were systematically tested for SARS-CoV-2 and had daily temperatures assessed from March to August, 2020. Lower baseline temperatures, and in SARS-CoV-2+ , lower maximum temperatures were observed with advancing age. Clinicians should be aware of the potential diminished fever response in the elderly with SARS-CoV-2.

Prevalence of Alzheimer's disease and related dementias among veterans experiencing housing insecurity.

INTRODUCTION: Housing insecure veterans are aging, but the prevalence of Alzheimer's disease and related dementias (AD/ADRD) in the population is unknown. METHODS: We calculated the prevalence of AD/ADRD diagnoses in 2018 among veterans that experienced homelessness, were at-risk for homelessness, or were stably housed. We determined acute care (emergency department, hospitalizations, psychiatric hospitalizations), and any long-term care (nursing home, and community-based) use by housing status among veterans with an AD/ADRD diagnosis. RESULTS: The overall prevalence of AD/ADRD diagnoses for homeless, at-risk, and stably housed veterans was 3.66%, 13.48%, and 3.04%, respectively. Housing insecure veterans with AD/ADRD used more acute care, and were more likely to have a nursing home admission compared to stably housed veterans. At risk, but not homeless veterans, were more likely to use US Department of Veterans Affairs-paid home and community-based care than stably housed veterans. DISCUSSION: The prevalence of AD/ADRD diagnoses is greater among housing insecure veterans than stably housed veterans.

Influencing Factors Associated with Implementation of INTERACT (Interventions to Reduce Acute Care Transfers) in VA Community Living Centers (CLCs) Using the Consolidated Framework.

Our objective was to identify the influencing factors associated with the implementation of the INTERACT (Interventions to Reduce Acute Care Transfers) Quality Improvement program within a national healthcare system. INTERACT focuses on early identification and management of changes in residents' condition leading to a reduction in potentially preventable hospital transfers. The Consolidated Framework was used to evaluate implementation data from eight VA Community Living Centers. Qualitative implementation data suggest two influencing Consolidated Framework domains had a strong influence: 1) key attributes of the intervention (e.g., adaptability or complexity) and 2) internal organizational factors (e.g., culture or compatibility). Using the Consolidated Framework can assist future adaptations to this and other complex quality improvement initiatives.

Adjuvanted Influenza Vaccine and Influenza Outbreaks in US Nursing Homes: Results From a Pragmatic Cluster-Randomized Clinical Trial.

BACKGROUND: Influenza outbreaks in nursing homes pose a threat to frail residents and occur even in vaccinated populations. We conducted a pragmatic cluster-randomized trial comparing adjuvanted trivalent influenza vaccine (aTIV) versus trivalent influenza vaccine (TIV). We report an exploratory analysis to compare the effect of aTIV versus TIV on facility-reported influenza outbreaks. METHODS: We evaluated the impact of the intent-to-treat vaccine assignment on outbreaks reported from November 2016 to March 2017. We collected data according to standard CDC definitions for both suspected outbreaks and those with a laboratory-confirmed case and adjusted for facility-level vaccination rates and resident characteristics in nursing homes. RESULTS: Of 823 randomized nursing homes, 777 (aTIV, n = 387; TIV, n = 390) reported information on influenza outbreaks. Treatment groups had similar characteristics at baseline except for race/ethnicity: homes assigned to TIV had a higher percentage of African-American residents (18.0% vs 13.7%). There were 133 versus 162 facility-reported suspected influenza outbreaks in aTIV versus TIV facilities, respectively; of these, 115 versus 140 were laboratory confirmed. The aTIV group experienced a 17% reduction in suspected (rate ratio, .83; 95% confidence interval, .65-1.05) and laboratory-confirmed (.83; .63-1.06) influenza outbreaks. Covariate adjustment increased the estimated reduction for suspected outbreaks to 21% (.79; .61-.99) and 22% for laboratory-confirmed outbreaks (.78; .60-1.02). CONCLUSIONS: In an exploratory analysis of a cluster-randomized trial we observed 17-21% fewer outbreaks with aTIV than TIV. Clinical Trials Registration. (NCT02882100).

Frailty Status and Patient-Reported Outcomes in Octogenarians Following Transcatheter or Surgical Aortic Valve Replacement.

BACKGROUND: Frailty status and patient-reported outcomes are especially pertinent in octogenarians following transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) to guide treatment decisions and promote patient-centred care. AIM: We aimed to determine if frailty changed 6 months after aortic valve replacement (AVR) in octogenarians, and to describe changes in self-rated health according to frailty status in patients who underwent TAVI or SAVR. METHOD: In a prospective cohort study, frailty and self-rated health were measured one day prior to and 6 months after AVR. Frailty status was measured with the Study of Osteoporotic Fracture index. Self-rated health was measured comprehensively with the disease-specific Minnesota Living with Heart Failure Questionnaire, the generic Medical Outcomes Study Short Form-12 questionnaire (SF-12), and two global questions from The World Health Organization Quality of Life Instrument Abbreviated. RESULTS: Data were available for 143 consecutive patients (mean age 83±2.7 years, 57% women; 45% underwent TAVI). At baseline, 34% were robust, 27% prefrail, and 39% frail. Overall, there was no change in the distribution of frailty status 6 months after baseline (p=0.13). However, on an individual level 65 patients changed frailty status after AVR (40 patients improved and 25 declined). Improvement in frailty status was common in prefrail (33%; n=13) and frail patients (48%; n=27). Patients had improved self-rated health after AVR, with significant differences between frailty states both at baseline (SF-12 physical: 37.4 [robust], 33.1 [prefrail], 31.6 [frail], p=0.03); SF-12 mental: 51.9 [robust], 50.8 [prefrail], 44.5 [frail], p<0.001); and at the 6-month follow-up (SF-12 physical: 45.4 [robust], 38.3 [prefrail], 32.1 [frail], p<0.001); SF-12 mental: 54.9 [robust], 49.6 [prefrail], 46.8 [frail], p=0.002). CONCLUSIONS: Advanced treatment performed in a high-risk population allowed people to improve their self-rated health. Although frailty is associated with poor self-rated health, frailty status does not equal negative outcomes. The frail patients were those who improved most in self-rated physical and mental health. They had the lowest baseline self-rated health scores and had therefore the most to gain.

Social work and telehealth: How Patient Aligned Care Team (PACT) social workers in the Veterans Health Administration responded to COVID-19.

In March 2020, the Veterans Health Administration (VA) responded to pandemic shutdowns with a rapid pivot toward providing services via telehealth. Using data on Veterans who received interventions from social workers between 2019 and 2020 at sites that participated in a national program to increase social work staffing in primary care, we examined changes in frequency and modality of social work encounters that occurred with the onset of the COVID-19 pandemic. We found that primary care social workers maintained a consistent level of engagement, with increases in telephone and video telehealth encounters as in-person visits decreased. Through front-line perspectives, we discuss the practical innovations and policies that enabled those changes in care from VA primary care social workers.

Interorganizational Context When Implementing Multisector Partnered Programs: A Qualitative Analysis of Veteran Directed Care.

As the number of Veterans enrolled in the Veterans Health Administration (VHA) and at risk for needing Long Term Services and Supports increases, VHA is shifting from institutional to Home and Community Based Services, such as the Veteran-Directed Care (VDC) program. VDC is a multi-sector program implemented as a collaboration between individual VHA medical centers (VAMCs) and Aging and Disability Network Agencies (ADNAs), entities that sit outside the VHA. Factors that affect establishment of effective multi-sector programs such as VDC are poorly understood, limiting ability to effectively deliver and scale programs. We conducted a qualitative study to describe factors affecting the interorganizational implementation context of VDC. Using constructs from the Consolidated Framework for Implementation Research (CFIR), we interviewed VDC coordinators from seven different VAMC-ADNA partnerships that initiated the VDC program between 2017 and 2018. We identified eight CFIR determinants which manifested similarly for the VAMCs and ADNAs: evidence strength and quality, relative advantage, adaptability, tension for change, access to knowledge and information, self-efficacy; engaging, and champions. We identified three CFIR determinants that varied dramatically across VAMCs and ADNAs: available resources, implementation climate, and relative priority. Our results suggest that interorganizational context plays a critical and dynamic role within multi-sector collaborations.
