Utilization of whole health services among veterans with spinal cord injuries and disorders (SCI/D): Early insights from the VA SCI/D system of care.

CONTEXT/OBJECTIVE: Our objective was to describe early participation in Whole Health programs across the Veterans Health Administration (VHA) Spinal Cord Injuries and Disorders (SCI/D) System of Care. DESIGN: Retrospective analysis of VHA administrative data. SETTING: The VHA SCI/D System of Care. PARTICIPANTS: Veterans with SCI/D included in the FY2019 cumulative VHA SCI/D Registry cohort with living status during FY2017, FY2018, and FY2019. INTERVENTIONS: N/A. OUTCOME MEASURES: We assessed the number of encounters and unique Veterans with SCI/D, and the percent of Veterans with SCI/D, who utilized each Whole Health (WH) program available in VA. RESULTS: Utilization of WH Pathway and well-being Programs increased from 62 encounters to 1703 encounters between FY2017 and FY2019 (representing 0.09% to 3.13% of Veterans with SCI/D). Utilization of chiropractic care rose from 130 encounters to 418 encounters during the same time period. Similarly, utilization of complementary and integrative health programs increased from 886 encounters to 2655 encounters (representing 1.09% to 3.11% of Veterans; FY2017 to 2019). We also report utilization of specific WH programs. CONCLUSION: Participation in WH services has been increasing among Veterans with SCI/D who receive health care from the VHA SCI/D System of Care. However, utilization among Veterans with SCI/D remains low overall, and targeted efforts to increase WH program reach are needed. Additional information about the relative effectiveness of different strategies to support WH implementation is also needed, to ensure strategies likely to have the most impact are prioritized.

VHA Whole Health Services and Complementary and Integrative Health Therapies: a Gateway to Evidence-Based Mental Health Treatment.

BACKGROUND: Engagement in evidence-based psychotherapy (EBP) among veterans with behavioral health conditions is often low. The Veterans Health Administration (VHA) is implementing a "Whole Health (WH)" system of care, to identify veteran personal health goals, align care with those goals, and offer services designed to engage and empower veterans to achieve well-being. OBJECTIVE: To examine the relationship between veteran WH utilization and subsequent engagement in EBP. DESIGN: Retrospective analysis of VHA administrative records from 18 facilities implementing WH. SUBJECTS: Veterans (n = 265,364) with a diagnosis of depression, post-traumatic stress disorder (PTSD), and/or anxiety who had a mental healthcare encounter but no EBP use in fiscal year (FY) 2018. Among this cohort, 33,146 (12.5%) began using WH in FY2019. MAIN MEASURES: We examined use of an EBP for depression, anxiety, and/or PTSD within 1 year of the index date of WH use compared to use of an EBP anytime during FY2019 for veterans not identified as using WH. We used multiple logistic regression to examine the association between veteran WH use and EBP engagement. KEY RESULTS: Approximately 3.0% (n = 7,860) of the veterans in our overall cohort engaged in an EBP in the year following their index date. Controlling for key demographic, health, and utilization variables, WH users had 2.4 (95% CI: 2.2-2.5) times higher odds of engaging in an EBP the following year than those with no WH utilization. Associations between utilization of specific WH services (vs. no utilization of that service) and engagement in an EBP in the subsequent year ranged from 1.6 (95% CI: 1.0-2.6) to 3.5 (95% CI: 3.2-3.9) across the different types of WH services used. CONCLUSIONS: WH use was associated with increased engagement in EBPs among veterans with depression, anxiety, and/or PTSD. Future interventions intended to promote veteran engagement in EBPs may benefit from leveraging WH services and therapies.

Using a person-centered approach in clinical care for patients with complex chronic conditions: Perspectives from healthcare professionals caring for Veterans with COPD in the U.S. Veterans Health Administration's Whole Health System of Care.

BACKGROUND: The largest nationally integrated health system in the United States, the Veterans Health Administration (VHA), has been undergoing a transformation toward a Whole Health (WH) System of Care. WH Clinical Care, a component of this system, includes holistically assessing the Veteran's life context, identifying what really matters to the Veteran, collaboratively setting and monitoring personal health and well-being goals, and equipping the Veteran with access to conventional and complementary and integrative health resources. Implementation of WH Clinical Care has been challenging. Understanding healthcare professionals' perspectives on the value of and barriers and facilitators to practicing WH Clinical Care holds relevance for not only VHA's efforts but also other health systems, in the U.S. and internationally, that are engaged in person-centered care implementation. OBJECTIVES: We sought to understand perspectives of healthcare professionals at VHA on providing WH Clinical Care to Veterans with COPD, as a lens to understand the broader issue of WH Clinical Care for Veterans living with complex chronic conditions. DESIGN: We interviewed 25 healthcare professionals across disciplines and services at a VA Medical Center in 2020-2021, including primary care providers, pulmonologists, palliative care providers, and chaplains. Interview transcripts were analyzed using qualitative content analysis. KEY RESULTS: Each element of WH Clinical Care raised complex questions and/or concerns, including: (1) the appropriate depth/breadth of inquiry in person-centered assessment; (2) the rationale for elicitation of what really matters; (3) the feasibility and appropriate division of labor in personal health goal setting and planning; and (4) challenges related to referring Veterans to a broad spectrum of supportive services. CONCLUSIONS: Efforts to promote person-centered care must account for healthcare professionals' existing comfort with its elements, advocate for a team-based approach, and continue to grapple with the conflicting structural conditions and organizational imperatives.

Association of Race and Ethnicity With Incidence of Dementia Among Older Adults.

Importance: The racial and ethnic diversity of the US, including among patients receiving their care at the Veterans Health Administration (VHA), is increasing. Dementia is a significant public health challenge and may have greater incidence among older adults from underrepresented racial and ethnic minority groups. Objective: To determine dementia incidence across 5 racial and ethnic groups and by US geographical region within a large, diverse, national cohort of older veterans who received care in the largest integrated health care system in the US. Design, Setting, and Participants: Retrospective cohort study within the VHA of a random sample (5% sample selected for each fiscal year) of 1 869 090 participants aged 55 years or older evaluated from October 1, 1999, to September 30, 2019 (the date of final follow-up). Exposures: Self-reported racial and ethnic data were obtained from the National Patient Care Database. US region was determined using Centers for Disease Control and Prevention (CDC) regions from residential zip codes. Main Outcomes and Measures: Incident diagnosis of dementia (9th and 10th editions of the International Classification of Diseases). Fine-Gray proportional hazards models were used to examine time to diagnosis, with age as the time scale and accounting for competing risk of death. Results: Among the 1 869 090 study participants (mean age, 69.4 [SD, 7.9] years; 42 870 women [2%]; 6865 American Indian or Alaska Native [0.4%], 9391 Asian [0.5%], 176 795 Black [9.5%], 20 663 Hispanic [1.0%], and 1 655 376 White [88.6%]), 13% received a diagnosis of dementia over a mean follow-up of 10.1 years. Age-adjusted incidence of dementia per 1000 person-years was 14.2 (95% CI, 13.3-15.1) for American Indian or Alaska Native participants, 12.4 (95% CI, 11.7-13.1) for Asian participants, 19.4 (95% CI, 19.2-19.6) for Black participants, 20.7 (95% CI, 20.1-21.3) for Hispanic participants, and 11.5 (95% CI, 11.4-11.6) for White participants. Compared with White participants, the fully adjusted hazard ratios were 1.05 (95% CI, 0.98-1.13) for American Indian or Alaska Native participants, 1.20 (95% CI, 1.13-1.28) for Asian participants, 1.54 (95% CI, 1.51-1.57) for Black participants, and 1.92 (95% CI, 1.82-2.02) for Hispanic participants. Across most US regions, age-adjusted dementia incidence rates were highest for Black and Hispanic participants, with rates similar among American Indian or Alaska Native, Asian, and White participants. Conclusions and Relevance: Among older adults who received care at VHA medical centers, there were significant differences in dementia incidence based on race and ethnicity. Further research is needed to understand the mechanisms responsible for these differences.

Complementary and integrative medicine perspectives among veteran patients and VHA healthcare providers for the treatment of headache disorders: a qualitative study.

OBJECTIVE: To evaluate veteran patient and provider perceptions and preferences on complementary and integrative medicine (CIM) for headache management. BACKGROUND: The Veterans Health Administration (VHA) has spearheaded a Whole Health system of care focusing on CIM-based care for veteran patients. Less is known about patients' and providers' CIM perceptions and preferences for chronic headache management. METHODS: We conducted semi-structured interviews with 20 veteran patients diagnosed with headache and 43 clinical providers, across 12 VHA Headache Centers of Excellence (HCoE), from January 2019 to March 2020. We conducted thematic and case comparative analyses. RESULTS: Veteran patients and VHA clinical providers viewed CIM favorably for the treatment of chronic headache. Specific barriers to CIM approaches included: (1) A lack of personnel specialized in specific CIM approaches for timely access, and (2) variation in patient perceptions and responses to CIM treatment efficacy for headache management. CONCLUSION: Veteran patients and VHA clinical providers in this study viewed CIM favorably as a safe addition to mainstream headache treatments. Advantages to CIM include favorable adverse effect profiles and patient autonomy over the treatment. By adding more CIM providers and resources throughout the VHA, CIM modalities may be recommended more routinely in the management of veterans with headache.

Shifting the Paradigm: A Population Health Approach to the Management of Direct Oral Anticoagulants.

Over the past decade, direct oral anticoagulants (DOACs) have contributed to a major paradigm shift in thrombosis management, replacing vitamin K antagonists as the most commonly prescribed anticoagulants in many countries. While DOACs provide distinct advantages over warfarin (eg, convenience, simplicity, and safety), they are frequently associated with inappropriate prescribing and adverse events. These events have prompted regulatory agencies to mandate oversight, which individual institutions may find difficult to comply with given limited resources. Veterans Health Administration (VHA) has leveraged technology to develop the DOAC Population Management Tool (PMT) to address these challenges. This tool has empowered VHA to update a 60-year standard of care from one-to-one provider-to-patient anticoagulation monitoring to a population-based management approach. The DOAC PMT allows for the oversight of all patients prescribed DOACs and leads to intervention only when clinically indicated. Using the DOAC PMT, facilities across VHA have maximized DOAC oversight while minimizing resource usage. Herein, we discuss how the DOAC PMT was conceived, developed, and implemented, along with the challenges encountered throughout the process. Additionally, we share the impact of the DOAC PMT across VHA, and the potential of this approach beyond anticoagulation and VHA.

Health Care for Our Nation's Veterans: A Policy Paper From the American College of Physicians.

The Veterans Health Administration (VHA) is the United States' largest integrated health care delivery system, serving over 9 million enrollees at nearly 1300 health care facilities. In addition to providing health care to the nation's military veterans, the VHA has a research and development program, trains thousands of medical residents and other health care professionals, and conducts emergency preparedness and response activities. The VHA has been celebrated for delivering high-quality care to veterans, early adoption of electronic medical records, and high patient satisfaction. However, the system faces challenges, including implementation of an expanded community care program, modernization of its electronic medical records system, and providing care to a population with complex needs. The position paper offers policy recommendations on VHA funding, the community care program, medical and health care professions training, and research and development.

Introducing clinical pharmacy specialists into interprofessional primary care teams: Assessing pharmacists' team integration and access to care for rural patients.

ABSTRACT: Clinical pharmacy specialists (CPS) were deployed nationally to improve care access and relieve provider burden in primary care.The aim of this study was to assess CPS integration in primary care and the Clinical Pharmacy Specialist Rural Veteran Access (CRVA) initiative's effectiveness in improving access.Concurrent embedded mixed-methods evaluation of participating CRVA CPS and their clinical team members (primary care providers, others).Health care providers on primary care teams in Veterans Health Administration (VHA).Perceived CPS integration in comprehensive medication management assessed using the MUPM and semi-structured interviews, and access measured with patient encounter data.There were 496,323 medical encounters with CPS in primary care over a 3-year period. One hundred twenty-four CPS and 1177 other clinical team members responded to a self-administered web-based questionnaire, with semi-structured interviews completed by 22 CPS and clinicians. Survey results indicated that all clinical provider groups rank CPS as making major contributions to CMM. CPS ranked themselves as contributing more to CMM than did their physician team members. CPS reported higher job satisfaction, less burn out, and better role fit; but CPS gave lower scores for communication and decision making as clinic organizational attributes. Themes in provider interviews focused on value of CPS in teams, relieving provider burden, facilitators to integration, and team communication issues.This evaluation indicates good integration of CPS on primary care teams as perceived by other team members despite some communication and role clarification challenges. CPS may play an important role in improving access to primary care.

Chemoradiation treatment patterns among United States Veteran Health Administration patients with unresectable stage III non-small cell lung cancer.

BACKGROUND: The Veterans Health Administration (VHA) is the largest integrated health care system in the United States (US). Among VHA patients, the rate of use of concurrent chemoradiation therapy (CCRT) among those with unresectable, stage III non-small cell lung cancer (NSCLC) is unknown. The objective was to report recent CCRT treatment patterns in VHA patients and identify characteristics associated with receipt of CCRT. METHODS: Using Department of Veteran Affairs (VA) Cancer Registry System data linked to VA electronic medical records, we determined rates of CCRT, sequential CRT (SCRT), radiation therapy (RT) only, chemotherapy (CT) only, and neither treatment. RESULTS: Among 4054 VHA patients who met study criteria, CCRT rates slightly increased from 44 to 50% between 2013 and 2017. Factors associated with decreased odds of CCRT receipt compared to any other treatment included increasing age (adjusted odds ratio [aOR] per 10 years = 0.67; 95% CI: 0.60-0.76) and Charlson-Deyo comorbidity score (aOR = 0.94; 95% CI: 0.91-0.97). White race was associated with increased odds of CCRT receipt (aOR = 1.24; 95% CI: 1.004-1.53). In a chart review sample of 200 patients, less than half (n = 85) had a documented reason for not receiving CCRT. Among these, 29% declined treatment, and 71% did not receive CCRT due to "not being a candidate" for reasons related to frailty or lung nodules being too far apart for radiation therapy. CONCLUSIONS: CCRT rates among VHA patients with unresectable, stage III NSCLC slightly increased from 2013 to 2017; however in 2017, only half were receiving CCRT. Older patients and those with multiple comorbidities were less likely to receive CCRT and even when controlling for these factors, non-white patients were less likely to receive CCRT.

Variability and Costs of Low-Value Preoperative Testing for Cataract Surgery Within the Veterans Health Administration.

Importance: The Choosing Wisely guidelines indicate that preoperative testing is often unnecessary and wasteful for patients undergoing cataract operations. However, little is known about the impact of these widely disseminated guidelines within the US Veterans Health Administration (VHA) system. Objective: To examine the extent, variability, associated factors, and costs of low-value tests (LVTs) prior to cataract operations in the VHA. Design, Setting, and Participants: This cohort study examined records of all patients receiving cataract operations within the VHA in fiscal year 2017 (October 1, 2016, to September 31, 2017). Records from 135 facilities nationwide supporting both ambulatory and inpatient surgery were included. Exposures: A laboratory test occurring within 30 days prior to cataract surgery and within 30 days after clinic evaluation. Main Outcomes and Measures: Overall national and facility-level rates and associated costs of receiving any of 8 common LVTs in the 30 days prior to cataract surgery. The patient characteristics, procedure type, and facility-level factors associated with receiving at least 1 test, the number of tests received, and receipt of a bundle of 4 tests (complete blood count, basic metabolic profile, chest radiograph, and electrocardiogram). Results: A total of 69 070 cataract procedures were identified among 50 106 patients (66 282 [96.0%] men; mean [SD] age, 71.7 [8.1] years; 53 837 [77.9%] White, 10 292 [14.9%] Black). Most of the patient population had either overweight (23 292 [33.7%] patients) or obesity (27 799 [40.2%] patients). Approximately 49% of surgical procedures (33 424 procedures) were preceded by 1 or more LVT with an overall LVT cost of $2 597 623. Among patients receiving LVTs, electrocardiography (7434 patients [29.9%]) was the most common, with some patients also receiving more costly tests, including chest radiographs (489 patients [8.2%]) and pulmonary function tests (127 patients [3.4%]). For receipt of any LVT, the intraclass correlation coefficient was 0.61 (P < .001) at the facility level and 0.06 (P < .001) at the surgeon level, indicating the substantial contribution of the facility to amount of tests given. Conclusions and Relevance: Despite existing guidelines, use of LVTs prior to cataract surgery is both common and costly within a large, national integrated health care system. Our results suggest that publishing evidence-based guidelines alone-such as the Choosing Wisely campaign-may not sufficiently influence individual physician behavior, and that system-level efforts to directly deimplement LVTs may therefore necessary to effect sustained change.

Understanding VA's Use of and Relationships With Community Care Providers Under the MISSION Act.

BACKGROUND: Congress has enacted 2 major pieces of legislation to improve access to care for Veterans within the Department of Veterans Affairs (VA). As a result, the VA has undergone a major transformation in the way that care is delivered to Veterans with an increased reliance on community-based provider networks. No studies have examined the relationship between VA and contracted community providers. This study examines VA facility directors' perspectives on their successes and challenges building relationships with community providers within the VA Community Care Network (CCN). OBJECTIVES: To understand who VA facilities partner with for community care, highlight areas of greatest need for partnerships in various regions, and identify challenges of working with community providers in the new CCN contract. RESEARCH DESIGN: We conducted a national survey with VA facility directors to explore needs, challenges, and expectations with the CCN. RESULTS: The most common care referred to community providers included physical therapy, chiropractic, orthopedic, ophthalmology, and acupuncture. Open-ended responses focused on 3 topics: (1) Challenges in working with community providers, (2) Strategies to maintain strong relationships with community providers, and (3) Re-engagement with community providers who no longer provide care for Veterans. CONCLUSIONS: VA faces challenges engaging with community providers given problems with timely reimbursement of community providers, low (Medicare) reimbursement rates, and confusing VA rules related to prior authorizations and bundled services. It will be critical to identify strategies to successfully initiate and sustain relationships with community providers.

Tele-Integrative Medicine to Support Rehabilitative Care.

Complementary and integrative health (CIH) modalities have therapeutic value in the multidisciplinary rehabilitation of chronic pain patients. Evidence of such has been seen with the Whole Health Model at the (Veterans Affairs) VA Healthcare system. CIH therapies, including yoga, tai chi, mindfulness meditation, hypnosis, self-massage, and acupressure, are significantly effective for managing chronic pain with little to no negative effects, and can be easily incorporated into telemedicine care with great potential benefit. The future of wellness in telemedicine is evolving with great potential, and needs further attention to addressing barriers of care.

Big Data in the Veterans Health Administration: A Nursing Informatics Perspective.

PURPOSE: This article reviews the missions of the U.S. Department of Veterans Affairs (VA) and the evolution of its electronic health record (EHR), the Veterans Health Information Systems and Technology Architecture (VistA). This system, along with its clinical graphical user interface the Computerized Patient Record System, form a key link in VA health care. A Veteran who receives healthcare through the VA can have their EHR accessed by clinicians at any VA healthcare facility across the United States and its territories. Data aggregated daily at a corporate data warehouse supports VA quality improvement and research. ORGANIZING CONSTRUCT: Serving over 9 million Veterans, the VA is one of the largest integrated healthcare systems in the United States. It has been a leader in the development and use of healthcare informatics, EHR, and big data analytics for over 30 years. Nurses engaged in major roles in the evolution of these developments. CONCLUSIONS: With over 500 nurses as members, the Office of Nursing Informatics' Field Alliance demonstrates the VA's continuing commitment to fostering nursing informatics. The commitment includes investment by the VA to develop nursing informaticists from among its own staff. CLINICAL RELEVANCE: Exemplars of the impact of nursing informatics are shared. Future directions include an EHR that begins during military service and follows the Veteran into VA health care.

Garnering Support for Complementary and Integrative Health Implementation: A Qualitative Study of VA Healthcare Organization Leaders.

Objectives: Healthcare organization leaders' support is critical for successful implementation of new practices, including complementary and integrative health (CIH) therapies. Yet little is known about how to garner this support and what motivates leaders to support these therapies. We examined reasons leaders provided or withheld support for CIH therapy implementation, using a multilevel lens to understand motivations influenced by individual, interpersonal, organizational, and system determinants. Design and setting: We conducted qualitative interviews with leaders in seven Veterans Health Administration medical centers that offered at least three CIH therapies to Veterans and were identified as early adopters of CIH therapies. Subjects: Participants included 12 executive leaders and 34 leaders of key clinical services, including primary care, mental health, physical medicine and rehabilitation, and pain. Measures: We used a thematic analysis to examine leaders' narratives of barriers and facilitators to implementation including their attitudes toward CIH therapies, perceptions of evidence, engagement in implementation, and decisions to provide concrete support for CIH therapies. Drawing from Greenhalgh's Diffusion of Innovation framework, we organized themes according to the influence of individual determinants, two levels of inner setting, and outer system context on CIH implementation. Results: Leaders' decisions to provide or withhold support were driven by considerations across multiple levels including (1) individual attitudes/knowledge, perceptions of evidence, and personal experiences; (2) interpersonal interactions with trusted brokers, patients, and loved ones/colleagues/staff; (3) organizational concerns surrounding relative priorities, local resources, and metrics/quality/safety; and (4) system-level policy, bureaucracy, and interorganizational networks. These considerations interacted across levels, with components at organizational and system levels sometimes prevailing over individual perceptions and experiences. Conclusions: Garnering leaders' support for CIH therapy implementation should address their considerations at multiple levels. Implementation strategies designed to shift individual attitudes alone may be insufficient for securing leaders' support without attention to broader organizational and system-level contextual issues.

Complementary and Integrative Health Approaches Offered in the Veterans Health Administration: Results of a National Organizational Survey.

Introduction: Certain complementary and integrative health (CIH) approaches have increasingly gained attention as evidence-based nonpharmacological options for pain, mental health, and well-being. The Veterans Health Administration (VA) has been at the forefront of providing CIH approaches for years, and the 2016 Comprehensive Addiction and Recovery Act mandated the VA expand its provision of CIH approaches. Objective/Design: To conduct a national organizational survey to document aspects of CIH approach implementation from August 2017 to July 2018 at the VA. Participants: CIH program leads at VA medical centers and community-based outpatient clinics (n = 196) representing 289 sites participated. Measures: Delivery of 27 CIH and other nonpharmacologic approaches was measured, including types of departments and providers, visit format, geographic variations, and implementation challenges. Results: Respondents reported offering a total of 1,568 CIH programs nationally. Sites offered an average of five approaches (range 1-23), and 63 sites offered 10 or more approaches. Relaxation techniques, mindfulness, guided imagery, yoga, and meditation were the top five most frequently offered. The most approaches were offered in physical medicine and rehabilitation, primary care, and within integrative/whole health programs, and VA non-Doctor of Medicine clinical staff were the most common type of CIH provider. Only 13% of sites reported offering CIH approaches through telehealth at the time. Geographically, southwestern sites offered the smallest number of approaches. Implementation challenges included insufficient staffing, funding, and space, hiring/credentialing, positioning CIH as a priority, and high patient demand. Conclusions: The provision of CIH approaches was widespread at the VA in 2017-2018, with over half of responding sites offering five or more approaches. As patients seek nonpharmacologic options to address their pain, anxiety, depression, and well-being, the nation's largest integrated health care system is well-positioned to meet that demand. Providing these therapies might not only increase patient satisfaction but also their health and well-being with limited to no adverse events.

Hypoglossal Nerve Stimulation in Veterans With Comorbid Insomnia and Sleep Apnea.

OBJECTIVE: Insomnia and sleep apnea frequently co-occur, with additive effects of both disorders presenting clinicians with unique treatment challenges compared to one disorder alone. The hypoglossal nerve stimulator (HNS) is a promising treatment for patients with comorbid insomnia and sleep apnea (COMISA), many of whom have positive airway pressure (PAP) intolerance. Our aim was to determine adherence to and efficacy of HNS in veterans with COMISA refractory to PAP therapy compared to those with obstructive sleep apnea alone (OSA only). STUDY DESIGN: Retrospective case series. SETTING: A single, academic Veterans Affairs medical center. METHODS: Review of clinical records, pre- and postoperative polysomnography, and clinical measures of obstructive sleep apnea (OSA), sleepiness, and insomnia was conducted in 53 consecutive cases of veterans with OSA undergoing HNS implantation. HNS adherence was obtained at postoperative visits. HNS adherence and efficacy were compared between individuals with COMISA and OSA only. RESULTS: COMISA was noted in 30 of 53 (56.6%) veterans studied. There was no significant difference between HNS adherence in patients with COMISA and OSA only (5.6 vs 6.4 h/night, P = .17). HNS implantation improved polysomnographic and clinical measures of OSA and sleepiness in both COMISA and OSA only, and 56.5% (13/23) of patients with COMISA self-reported improvement in insomnia after surgery. CONCLUSION: HNS was successful in treating a complex veteran population with COMISA refractory to PAP when examining measures of treatment adherence and efficacy. Future studies of patients with COMISA undergoing HNS will examine effective combination therapy targeting insomnia and a multidisciplinary effort to optimize treatment adherence.

Machine-Learning Models for Multicenter Prostate Cancer Treatment Plans.

Clinical factors, including T-stage, Gleason score, and baseline prostate-specific antigen, are used to stratify patients with prostate cancer (PCa) into risk groups. This provides prognostic information for a heterogeneous disease such as PCa and guides treatment selection. In this article, we hypothesize that nonclinical factors may also impact treatment selection and their adherence to treatment guidelines. A total of 552 patients with intermediate- and high-risk PCa treated with definitive radiation with or without androgen deprivation therapy (ADT) between 2010 and 2017 were identified from 34 medical centers within the Veterans Health Administration. Medical charts were manually reviewed, and details regarding each patient's clinical history and treatment were extracted. Support Vector Machine and Random forest-based classification was used to identify clinical and nonclinical predictors of adherence to the treatment guidelines from the National Comprehensive Cancer Network (NCCN). We created models for predicting both initial treatment intent and treatment alterations. Our results demonstrate that besides clinical factors, the center in which the patient was treated (nonclinical factor) played a significant role in adherence to NCCN guidelines. Furthermore, the treatment center served as an important predictor to decide on whether or not to prescribe ADT; however, it was not associated with ADT duration and weakly associated with treatment alterations. Such center-bias motivates further investigation on details of center-specific barriers to both NCCN guideline adherence and on oncological outcomes. In addition, we demonstrate that publicly available data sets, for example, that from Surveillance, Epidemiology, and End Results (SEERs), may not be well equipped to build such predictive models on treatment plans.

Management of patients with prior lumbar fusion: a cross-sectional survey of Veterans Affairs chiropractors' attitudes, beliefs, and practices.

BACKGROUND: Little is known about the preferred treatment strategies of chiropractors in managing low back pain patients with prior lumbar fusions. There are several case reports which describe chiropractic care following surgical intervention, but there are no cohort or experimental studies published. Therefore, we sought to examine self-reported management approaches and practice patterns related to the management of patients with prior surgical lumbar fusion, among United States Veterans Affairs (VA) chiropractors. METHODS: An electronic survey was administered nationwide to all chiropractors providing clinical care within VA. Questions were informed by a prior survey and piloted on a sample of chiropractors external to VA. Statistical analysis included respondent background information, and quantitative analysis of chiropractic referral patterns and practices. This survey collect information on 1) provider demographics, 2) VA referral patterns, and 3) attitudes, beliefs, practices and interventions utilized by VA chiropractors to manage patients with a history of surgical lumbar fusion. RESULTS: The survey response rate was 46.3% (62/134). The respondents were broadly representative of VA chiropractic providers in age, gender, and years in practice. The majority of respondents (90.3%) reported seeing at least 1 post-fusion patient in the past month. The most common therapeutic approaches utilized by VA chiropractors were healthy lifestyle advice (94.9%), pain education (89.8%), exercise prescription (88.1%), stretching (66.1%) and soft tissue manual therapies (62.7%). A relatively smaller proportion described always or frequently incorporating lumbar (16.9%), thoracic (57.6%) or pelvic (39.0%) spinal manipulation. CONCLUSION: This survey provides preliminary data on VA chiropractic services in the management of patients with prior lumbar fusion. These patients are often seen by VA chiropractors, and our findings support the need for further study to advance understanding of interventions utilized by chiropractors in this patient population.

Use of General Primary Care, Specialized Primary Care, and Other Veterans Affairs Services Among High-Risk Veterans.

Importance: Integrated health care systems increasingly focus on improving outcomes among patients at high risk for hospitalization. Examining patterns of where patients obtain care could give health care systems insight into how to develop approaches for high-risk patient care; however, such information is rarely described. Objective: To assess use of general and specialized primary care, medical specialty, and mental health services among patients at high risk of hospitalization in the Veterans Health Administration (VHA). Design, Setting, and Participants: This national, population-based, retrospective cross-sectional study included all veterans enrolled in any type of VHA primary care service as of September 30, 2015. Data analysis was performed from April 1, 2016, to January 1, 2019. Exposures: Risk of hospitalization and assignment to general vs specialized primary care. Main Outcome and Measures: High-risk veterans were defined as those who had the 5% highest risk of near-term hospitalization based on a validated risk prediction model; all others were considered low risk. Health care service use was measured by the number of encounters in general primary care, specialized primary care, medical specialty, mental health, emergency department, and add-on intensive management services (eg, telehealth and palliative care). Results: The study assessed 4 309 192 veterans (mean [SD] age, 62.6 [16.0] years; 93% male). Male veterans (93%; odds ratio [OR], 1.11; 95% CI, 1.10-1.13), unmarried veterans (63%; OR, 2.30; 95% CI, 2.32-2.35), those older than 45 years (94%; 45-65 years of age: OR, 3.49 [95% CI, 3.44-3.54]; 66-75 years of age: OR, 3.04 [95% CI, 3.00-3.09]; and >75 years of age: OR, 2.42 [95% CI, 2.38-2.46]), black veterans (23%; OR, 1.63; 95% CI, 1.61-1.64), and those with medical comorbidities (asthma or chronic obstructive pulmonary disease: 33%; OR, 4.03 [95% CI, 4.00-4.06]; schizophrenia: 4%; OR, 5.14 [95% CI, 5.05-5.22]; depression: 42%; OR, 3.10 [95% CI, 3.08-3.13]; and alcohol abuse: 20%; OR, 4.54 [95% CI, 4.50-4.59]) were more likely to be high risk (n = 351 012). Most (308 433 [88%]) high-risk veterans were assigned to general primary care; the remaining 12% (42 579 of 363 561) were assigned to specialized primary care (eg, women's health and homelessness). High-risk patients assigned to general primary care had more frequent primary care visits (mean [SD], 6.9 [6.5] per year) than those assigned to specialized primary care (mean [SD], 6.3 [7.3] per year; P < .001). They also had more medical specialty care visits (mean [SD], 4.4 [5.9] vs 3.7 [5.4] per year; P < .001) and fewer mental health visits (mean [SD], 9.0 [21.6] vs 11.3 [23.9] per year; P < .001). Use of intensive supplementary outpatient services was low overall. Conclusions and Relevance: The findings suggest that, in integrated health care systems, approaches to support high-risk patient care should be embedded within general primary care and mental health care if they are to improve outcomes for high-risk patient populations.

Strategy Configurations Directly Linked to Higher Hepatitis C Virus Treatment Starts: An Applied Use of Configurational Comparative Methods.

BACKGROUND: The Department of Veterans Affairs (VA) cares for more patients with hepatitis C virus (HCV) than any other US health care system. We tracked the implementation strategies that VA sites used to implement highly effective new treatments for HCV with the aim of uncovering how combinations of implementation strategies influenced the uptake of the HCV treatment innovation. We applied Configurational Comparative Methods (CCMs) to uncover causal dependencies and identify difference-making strategy configurations, and to distinguish higher from lower HCV treating sites. METHODS: We surveyed providers to assess VA sites' use of 73 implementation strategies to promote HCV treatment in the fiscal year 2015. CCMs were used to identify strategy configurations that uniquely distinguished higher HCV from lower HCV treating sites. RESULTS: From the 73 possible implementation strategies, CCMs identified 5 distinct strategy configurations, or "solution paths." These were comprised of 10 individual strategies that collectively explained 80% of the sites with higher HCV treatment starts with 100% consistency. Using any one of the following 5 solution paths was sufficient to produce higher treatment starts: (1) technical assistance; (2) engaging in a learning collaborative AND designating leaders; (3) site visits AND outreach to patients to promote uptake and adherence; (4) developing resource sharing agreements AND an implementation blueprint; OR (5) creating new clinical teams AND sharing quality improvement knowledge with other sites AND engaging patients. There was equifinality in that the presence of any one of the 5 solution paths was sufficient for higher treatment starts. CONCLUSIONS: Five strategy configurations distinguished higher HCV from lower HCV treating sites with 100% consistency. CCMs represent a methodological advancement that can help inform high-yield implementation strategy selection and increase the efficiency and effectiveness of future implementation efforts.
