Understanding How Contingency Staffing Programs Can Support Mental Health Services in the Veterans Health Administration.

Introduction: Beginning in 2019, the Department of Veterans Affairs (VA) prioritized improving access to care nationally to deliver virtual care and implemented 18 regionally based Clinical Resource Hubs (CRHs) to meet this priority. This observational study describes the quantity and types of care delivered by CRH Mental Health teams, and the professions of those hired to deliver it. Methods: A retrospective cohort study, based on national VA CRH mental health care utilization data and CRH staffing data for CRH's first 3 years, was conducted. Results: CRH Mental Health teams primarily used Telemental Health (TMH) to provide care (98.1% of all CRH MH encounters). The most common disorders treated included depression, post-traumatic stress disorder, and anxiety disorders. The amount of care delivered overtime steadily increased as did the racial and ethnic diversity of Veterans served. Psychologists accounted for the largest share of CRH staffing, followed by psychiatrists. Conclusions: CRH TMH delivered from a regional hub appears to be a feasible and acceptable visit modality, based on the continuously increasing CRH TMH visit rates. Our results showed that CRH TMH was predominantly used to address common mental health diagnoses, rather than serious mental illnesses. Traditionally marginalized patient populations increased over the 3-year window, suggesting that CRH TMH resources were accessible to many of these patients. Future research should assess barriers and facilitators for accessing CRH TMH, especially for difficult-to-service patient populations, and should consider whether similar results to ours occur when regional TMH is delivered to non-VA patient populations.

Determinants of Patient Aligned Care Team (PACT) members' burnout and its relationship with patient-centered care.

Burnout is a prevalent issue among healthcare providers affecting up to 54% of physicians and 35% of nurses. Patient Aligned Care Teams (PACT) is a team-based primary care delivery model designed to assure the delivery of high-quality care while improving clinicians' well-being. Limited studies evaluated the relationship between work environment variables and PACT members' burnout and the relationship between PACT members' burnout and patient-centered care. This cross-sectional study is based on the 2018 Veterans Health Administration (VHA) national web-based PACT survey. Burnout was measured using a single-item question that was validated in previous studies. Descriptive statistics and logistic regression were used to analyze the data. Fifty-one percent of primary care providers and 40.12% of nurses reported high burnout. PACT members with a work environment characterized by high-quality team interaction, leadership support, and psychological safety experienced lower levels of burnout. PACT members' burnout explained 6% of the variance in PACT members' ability to deliver patient-centered care. Burnout among PACT members is attributed to multiple personal and occupational variables. This study identified modifiable work environment variables that can be used to inform burnout interventions.

The Clinical Resource Hub Initiative: First-Year Implementation of the Veterans Health Administration Regional Telehealth Contingency Staffing Program.

Health care systems face challenges providing accessible health care across geographically disparate sites. The Veterans Health Administration (VHA) developed regional telemedicine service focusing initially on primary care and mental health services. The objective of this study is to describe the program and progress during the early implementation. In its first year, the Clinical Resource Hub program provided 244 515 encounters to 95 684 Veterans at 475 sites. All 18 regions met or exceeded minimum implementation requirements. The regionally based telehealth contingency staffing hub met early implementation goals. Further evaluation to review sustainability and impact on provider experience and patient outcomes is needed.

Association of Integrated Mental Health Services with Physical Health Quality Among VA Primary Care Patients.

BACKGROUND: Integrated care for comorbid depression and chronic medical disease improved physical and mental health outcomes in randomized controlled trials. The Veterans Health Administration (VA) implemented Primary Care-Mental Health Integration (PC-MHI) across all primary care clinics nationally to increase access to mental/behavioral health treatment, alongside physical health management. OBJECTIVE: To examine whether widespread, pragmatic PC-MHI implementation was associated with improved care quality for chronic medical diseases. DESIGN, SETTING, AND PARTICIPANTS: This retrospective cohort study included 828,050 primary care patients with at least one quality metric among 396 VA clinics providing PC-MHI services between October 2013 and September 2016. MAIN MEASURE(S): For outcome measures, chart abstractors rated whether diabetes and cardiovascular quality metrics were met for patients at each clinic as part of VA's established quality reporting program. The explanatory variable was the proportion of primary care patients seen by integrated mental health specialists in each clinic annually. Multilevel logistic regression models examined associations between clinic PC-MHI proportion and patient-level quality metrics, adjusting for regional, patient, and time-level effects and clinic and patient characteristics. KEY RESULTS: Median proportion of patients seen in PC-MHI per clinic was 6.4% (IQR=4.7-8.7%). Nineteen percent of patients with diabetes had poor glycemic control (hemoglobin A1c >9%). Five percent had severely elevated blood pressure (>160/100 mmHg). Each two-fold increase in clinic PC-MHI proportion was associated with 2% lower adjusted odds of poor glycemic control (95% CI=0.96-0.99; p=0.046) in diabetes. While there was no association with quality for patients diagnosed with hypertension, patients without diagnosed hypertension had 5% (CI=0.92-0.99; p=0.046) lower adjusted odds of having elevated blood pressures. CONCLUSIONS AND RELEVANCE: Primary care clinics where integrated mental health care reached a greater proportion of patients achieved modest albeit statistically significant gains in key chronic care quality metrics, providing optimism about the expected effects of large-scale PC-MHI implementation on physical health.

Association of Veterans Affairs Primary Care Mental Health Integration With Care Access Among Men and Women Veterans.

Importance: Women veterans increasingly seek care yet continue to face barriers in the Veterans Health Administration (VA), which predominantly cares for men. Evidence-based collaborative care models can improve patient access to treatment of depression, which is experienced at higher rates by women. While the VA has implemented these care models nationally, it is not known whether access improvements occur equitably across genders in primary care. Objective: To examine whether the VA's national Primary Care-Mental Health Integration (PC-MHI) initiative (beginning 2007) expanded realized access to mental health care similarly for men and women. Design, Setting, and Participants: This cohort study included 5 377 093 million primary care patients assigned to 396 VA clinics that provided integrated mental health services nationally between October 2013 and September 2016. Data analysis occurred between May 2017 and July 2020. Exposures: Clinic PC-MHI penetration, calculated as the proportion of clinic patients who saw an integrated specialist per fiscal year. Main Outcomes and Measures: Estimates of mean VA health care utilization (mental health, primary care, other specialty care, telephone, hospitalizations) and median total costs for men and women. Multilevel models adjusted for year, clinic, patient characteristics, and interactions between patient-defined gender and clinic PC-MHI penetration. Results: This study examined 5 377 093 veterans (448 455 [8.3%] women; 3 744 140 [69.6%] White) with a mean (SD) baseline age 62.0 (16.6) years. Each percentage-point increase in the proportion of clinic patients who saw an integrated specialist was associated with 38% fewer mental health visits per year for women (incidence rate ratio [IRR], 0.62; 95% CI, 0.60-0.65), but 39% more visits for men (IRR, 1.39; 95% CI, 1.34-1.44; P < .001). Both men and women had more primary care visits (men: IRR, 1.40; 95% CI, 1.36-1.45; women: IRR, 1.22; 95% CI, 1.17-1.28; P < .001) and total costs (men: ß [SE], 2.23 [0.10]; women: ß [SE], 1.24 [0.15]; P = .06), but women had 74% fewer hospitalizations than men related to clinics with mental health integration (IRR, 0.26; 95% CI, 0.19-0.36 vs IRR, 1.02; 95% CI, 0.83-1.24; P < .001). Conclusions and Relevance: While greater outpatient service use for men was observed in this study, PC-MHI was associated with a decrease in mental health specialty visits (and hospitalizations) for women veterans, potentially signifying a shift of services to primary care. With increasing patient choice for where veterans receive care, the VA must tailor medical care to the needs of rising numbers of women patients. Differences in health care utilization by gender highlight the importance of anticipating policy impacts on and tailoring services for patients in the numerical minority in the VA and other health systems.

Care Practices to Promote Patient Engagement in VA Primary Care: Factors Associated With High Performance.

PURPOSE: Patient engagement has been broadly defined as the process of actively involving and supporting patients in health care and treatment decision making. The aim of this study was to identify organizational factors that are associated with greater use of patient engagement care practices in Veterans Health Administration primary care clinics. METHODS: We conducted a cross-sectional analysis of data from the 2016 Patient-Aligned Care Team (PACT) national survey of direct care clinicians (primary care clinicians, registered nurses, and clinical associates). Exploratory factor analysis was used to group conceptually related patient engagement survey items into 3 subscales: planning and goal setting; motivational interviewing; and organizational strategies to promote self-management. Our independent variables included literature-based factors reported to promote team-based care and interdisciplinary collaboration in primary care. We used generalized estimating equations with multivariate logistic regression analysis to identify independent correlates of high performance on each patient engagement domain (top 25th vs bottom 25th percentile). RESULTS: A total of 2,478 direct care clinicians from 609 clinics completed all patient engagement items in the PACT survey. For all patient engagement sub-scales, respondents at high-performing clinics were more likely to report having regular team meetings to discuss performance improvement and having leadership responsible for implementing PACT. For 2 of 3 patient engagement subscales, high performance was also associated with having fully staffed PACT teams (≥3 team members per primary care clinician) and role clarity. CONCLUSIONS: Several desirable organizational and contextual factors were associated with high performance of patient engagement care practices. Strategies to improve the organizational functioning of primary care teams may enhance patient engagement in care.

The Effects of Telephone Visits and Rurality on Veterans Perceptions of Access to Primary Care.

INTRODUCTION: The objectives of this study were to examine if self-reported access to primary care is associated with actual patient wait times and use of telephone visits, and to assess whether this relationship differs by rural residence. METHODS: This study used 2016 administrative data from 994 primary care clinics within the Veterans Health Administration. Multiple-linear regression was used to examine relationships between patient perceptions of access and average actual patient wait time, use of telephone visits, and rural residence. Average panel size, clinic type, and panel severity were included as model covariates with cross-product terms for actual wait time, telephone use, and rurality to test for interactions. RESULTS: This study found patient perceptions of access aggregated at the clinic level to be conditional on the relationship between use of telephone visits, actual patient wait times, and rural residence. As actual wait time for routine appointments increases, Veterans served by clinics with a higher percent of rural Veterans perceive telephone visits more positively. DISCUSSION: These findings contribute to our understanding of factors associated with patient perceptions of access by highlighting complex interrelationships between strategies intended to improve access to care and how they can have differing impacts on perceptions among those living in rural or urban locations.

Veterans Health Administration Investments In Primary Care And Mental Health Integration Improved Care Access.

Aiming to increase care access, the national Primary Care-Mental Health Integration (PC-MHI) initiative of the Veterans Health Administration (VHA) embedded specialists, care managers, or both in primary care clinics to collaboratively care for veterans with psychiatric illness. The initiative's effects on health care use and cost patterns were examined among 5.4 million primary care patients in 396 VHA clinics in 2013-16. The median rate of patients who saw a PC-MHI provider was 6.3 percent. Each percentage-point increase in the proportion of clinic patients seen by these providers was associated with 11 percent more mental health and 40 percent more primary care visits but also with 9 percent higher average total costs per patient per year. At the mean, 2.5 integrated care visits substituted for each specialty-based mental health visit that did not occur. PC-MHI was associated with improved access to outpatient care, albeit at increased total cost to the VHA. Successful implementation of integrated care necessitates significant investment and multidisciplinary partnership within health systems.

Comparative analysis of salivary gland transcriptomes of Phlebotomus orientalis sand flies from endemic and non-endemic foci of visceral leishmaniasis.

BACKGROUND: In East Africa, Phlebotomus orientalis serves as the main vector of Leishmania donovani, the causative agent of visceral leishmaniasis (VL). Phlebotomus orientalis is present at two distant localities in Ethiopia; Addis Zemen where VL is endemic and Melka Werer where transmission of VL does not occur. To find out whether the difference in epidemiology of VL is due to distant compositions of P. orientalis saliva we established colonies from Addis Zemen and Melka Werer, analyzed and compared the transcriptomes, proteomes and enzymatic activity of the salivary glands. METHODOLOGY/PRINCIPAL FINDINGS: Two cDNA libraries were constructed from the female salivary glands of P. orientalis from Addis Zemen and Melka Werer. Clones of each P. orientalis library were randomly selected, sequenced and analyzed. In P. orientalis transcriptomes, we identified members of 13 main protein families. Phylogenetic analysis and multiple sequence alignments were performed to evaluate differences between the P. orientalis colonies and to show the relationship with other sand fly species from the subgenus Larroussius. To further compare both colonies, we investigated the humoral antigenicity and cross-reactivity of the salivary proteins and the activity of salivary apyrase and hyaluronidase. CONCLUSIONS: This is the first report of the salivary components of P. orientalis, an important vector sand fly. Our study expanded the knowledge of salivary gland compounds of sand fly species in the subgenus Larroussius. Based on the phylogenetic analysis, we showed that P. orientalis is closely related to Phlebotomus tobbi and Phlebotomus perniciosus, whereas Phlebotomus ariasi is evolutionarily more distinct species. We also demonstrated that there is no significant difference between the transcriptomes, proteomes or enzymatic properties of the salivary components of Addis Zemen (endemic area) and Melka Werer (non-endemic area) P. orientalis colonies. Thus, the different epidemiology of VL in these Ethiopian foci cannot be attributed to the salivary gland composition.
