(RE-)AIMing for Rapid Uptake: Pilot Evaluation of a Modified Hub and Spoke Model of Medication for Opioid Use Disorder.

OBJECTIVE: Medication for opioid use disorder (MOUD) is an effective, evidence-based treatment, but significant gaps in implementation remain. We evaluate one novel approach to address this gap: a Hub and Spoke model to increase buprenorphine access and management. METHODS: This outcome evaluation was guided by the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework using secondary data analysis of clinical and administrative data to characterize program outcomes for program Reach, Effectiveness, Adoption, and Maintenance. Implementation was assessed through a chart review of provider progress notes and through key informant interviews with program staff to understand why this site was able to introduce a novel approach to MOUD. RESULTS: Nearly half of patients with opioid use disorder (45.48%, n=156) were reached by the program over 2 years. Of those, 91.67% had 1 or more program visits after an initial intake appointment, and 78.85% had a buprenorphine prescription. Patients in the program were 2.44 times more likely to have a buprenorphine prescription than those in comparator site that did not have a Hub and Spoke program (95% CI: 1.77-3.37; P <0.001). There was significantly greater program reach in year 1 than year 2, suggesting rapid initial uptake followed by modest program growth. Key informant interviews illustrated several themes regrading program implementation, including the importance of process champions, the beneficial impact of MOUD for patients, and addressing facility performance metrics. A supportive organizational culture and a receptive climate were also key factors for implementation. CONCLUSIONS: This program led to rapid improvement in MOUD uptake across the facility. Future efforts should focus on improving program maintenance, including supporting the exchange of patients from the hub to appropriate spokes.

Adapting and Evaluating the Feasibility and Acceptability of a Behavioral Intervention to Promote Sleep Health in Cardiac Rehabilitation.

OBJECTIVES: Study objectives were to: 1) iteratively adapt the Transdiagnostic Sleep and Circadian Intervention (TranS-C) for patients in cardiac rehabilitation (CR; Phase 1) and 2) conduct a preliminary single group pre-post intervention test to a) evaluate procedural feasibility and intervention acceptability and b) to explore preliminary pre-post changes in self-reported sleep, disability, and health-related quality of life (HRQoL; Phase 2). METHOD: In Phase 1, 12 individuals in CR and six content experts completed interviews to inform TranS-C adaptations. Interviews were analyzed using rapid qualitative analysis. In Phase 2, eight individuals in CR completed a baseline assessment, the adapted TranS-C intervention, and a post-intervention assessment. Intervention acceptability was assessed via questionnaire and interview. Sleep, disability, and HRQoL outcomes were assessed using questionnaires. Descriptive statistics were calculated for quantitative measures; interviews were analyzed using rapid qualitative analysis. RESULTS: Phase 1 participants were receptive to the premise and structure of the adapted intervention. In Phase 2, participants endorsed positive attitudes toward the intervention. Seven of eight participants demonstrated improvements in sleep outcomes. Disability and HRQoL results did not consistently improve. CONCLUSION: The adapted TranS-C intervention was acceptable to CR patients and could yield improvements in subjective sleep outcomes. Larger-scale testing in CR is warranted.

Collaborative Care Models to Improve Pain and Reduce Opioid Use in Primary Care: a Systematic Review.

BACKGROUND: Collaborative care management (CCM) is an empirically driven model to overcome fractured medical care and improve health outcomes. While CCM has been applied across numerous conditions, it remains underused for chronic pain and opioid use. Our objective was to establish the state of the science for CCM approaches to addressing pain-related outcomes and opioid-related behaviors through a systematic review. METHODS: We identified peer-reviewed articles from Cochrane, Embase, PsycINFO, and PubMed databases from January 1, 1995, to October 31, 2022. Abstracts and full-text articles were screened for study inclusion, resulting in 18 studies for the final review. In addition, authors used the Patient-Centered Integrated Behavioral Health Care Principles and Tasks Checklist as a tool for assessing the reported CCM components within and across studies. We conducted this systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement. RESULTS: Several CCM trials evidenced statistically significant improvements in pain-related outcomes (n = 11), such as pain severity and pain-related activity interference. However, effect sizes varied considerably across studies and some effects were not clinically meaningful. CCM had some success in targeting opioid-related behaviors (n = 4), including reduction in opioid prescription dose. Other opioid-related work focused on CCM to facilitate buprenorphine treatment for opioid use disorder (n = 2), including improved odds of receiving treatment and greater prevalence of abstinence from opioids and alcohol. Uniquely, several interventions used CCM to target mental health as a way to address pain (n = 10). Generally, there was moderate alignment with the CCM model. CONCLUSIONS: CCM shows promise for improving pain-related outcomes, as well as facilitating buprenorphine for opioid use disorder. More robust research is needed to determine which aspects of CCM best support improved outcomes and how to maximize the effectiveness of such interventions.

Headache Disorders in VHA Primary Care: Prevalence, Psychiatric Comorbidity, and Health Care Utilization.

Military veterans are at increased risk for headache disorders compared to the general population, yet the prevalence and burden associated with headache disorders among veterans is not yet well understood. In this electronic medical record study, we examined the prevalence of headache disorders among veterans seen in a northeastern network of Veterans Health Administration (VHA) primary care during 2017-2018. We also examined rates of psychiatric comorbidity and health care utilization of veterans with headache disorders for the year following the date of the first headache code in the medical record. Of the total population of veterans in the network, 1.3% had a headache disorder and another 3.5% had a possible headache disorder. Migraine and chronic migraine represented the majority of cases. Posttraumatic stress disorder was the most frequent psychiatric comorbidity. Having a headache disorder was associated with higher rates of primary care, neurology, pain clinic, and mental health service use but not higher rates of emergency department or Whole Health (e.g., patient-centered, holistic health services) use. Prevalence findings are comparable to those previously found among veterans, but a substantial proportion of veterans may have been misdiagnosed. Veterans with headache disorders have high rates of psychiatric comorbidity and use several types of health services at higher rates. Findings highlight the need for interdisciplinary care and further education and support for primary care providers. Primary care settings that integrate evidence-based behavioral and Whole Health services may be an optimal way of providing more holistic care for headache disorders.

A Practical Guide to Applying the Delphi Technique in Mental Health Treatment Adaptation: The Example of Enhanced Problem-Solving Training (E-PST).

Expert consensus methods, such as the Delphi procedure, are commonly employed in consumer, education, and health services research. However, the utility of this methodology has not widely been described in relation to mental health treatment adaptation efforts. This gap is noteworthy given that evidence-based treatments are often modified in terms of core intervention content, method of delivery, and target populations. Expert consensus methods such as the Delphi procedure offer multiple practical benefits (e.g., flexibility, resource-efficiency) for psychologists who need to adapt existing treatments to meet new research and clinical practice needs. The purpose of this paper is to provide a brief overview of the Delphi procedure, and to offer a practical guide to using this method for treatment adaptation. An example is offered using our team's application of a three-round Delphi procedure to render content and context modifications to an existing problem-solving intervention to optimize its use with a new treatment population. Data were collected from Department of Veterans Affairs clinical subject matter experts. Round 1 utilized semi-structured interviews to determine necessary protocol features and modifications. Rounds 2-3 utilized a forced-choice survey and feedback loop to evaluate expert consensus. More than 91% of rated items reached consensus following Round 2, with the remainder following Round 3. Recommended modifications included minor structural and content edits, and re-balancing time allotments. We conclude that consensus methods may facilitate treatment adaptation efforts, enhance treatment feasibility, and promote content and ecological validity. Considerations for future Delphi-based treatment adaptations are offered.

Primary care and mental health providers' perceptions of implementation of pharmacogenetics testing for depression prescribing.

BACKGROUND: Pharmacogenetic testing (PGx) has the potential to improve the quality of psychiatric prescribing by considering patients' genetic profile. However, there is limited scientific evidence supporting its efficacy or guiding its implementation. The Precision Medicine in Mental Health (PRIME) Care study is a pragmatic randomized controlled trial evaluating the effectiveness of a specific commercially-available pharmacogenetic (PGx) test to inform antidepressant prescribing at 22 sites across the U.S. Simultaneous implementation science methods using the Consolidated Framework for Implementation Research (CFIR) are integrated throughout the trial to identify contextual factors likely to be important in future implementation of PGx. The goal of this study was to understand providers' perceptions of PGx for antidepressant prescribing and implications for future implementation. METHODS: Qualitative focus groups (n = 10) were conducted at the beginning of the trial with Primary Care and Mental Health providers (n = 31) from six PRIME Care sites. Focus groups were audio-recorded and transcribed and data were analyzed using rapid analytic procedures organized by CFIR domains. RESULTS: Analysis revealed themes in the CFIR Intervention Characteristics domain constructs of Evidence, Relative Advantage, Adaptability, Trialability, Complexity, and Design that are important for understanding providers' perceptions of PGx testing. Results indicate: 1) providers had limited experience and knowledge of PGx testing and its evidence base, particularly for psychiatric medications; 2) providers were hopeful that PGx could increase their precision in depression prescribing and improve patient engagement, but were uncertain about how results would influence treatment; 3) providers were concerned about potential misinterpretation of PGx results and how to incorporate testing into their workflow; 4) primary care providers were less familiar and comfortable with application of PGx testing to antidepressant prescribing than psychiatric providers. CONCLUSIONS: Provider perceptions may serve as facilitators or barriers to implementation of PGx for psychiatric prescribing. Incorporating implementation science into the conduct of the RCT adds value by uncovering factors to be addressed in preparing for future implementation, should the practice prove effective. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT03170362 ; Registered 31 May 2017.

Validation of an Expanded Measure of Integrated Care Provider Fidelity: PPAQ-2.

This study aimed to validate the factor structure of the expanded Primary Care Behavioral Health Provider Adherence Questionnaire (PPAQ-2), which is designed to assess provider fidelity to both the Primary Care Behavioral Health (PCBH) and collaborative care management (CCM) models of integrated primary care. Two-hundred fifty-three integrated care providers completed self-reports of professional background, perceptions of clinic integration and related practice barriers, and the PPAQ-2. Confirmatory factor analyses were conducted to assess the theorized factor structure and criterion validity was assessed through correlational analysis. Factor analyses demonstrated adequate fit with the data and acceptable to excellent composite reliabilities across five PCBH domains and five CCM domains. Validity was demonstrated by correlations between adherence scores and measures of clinic integration and barriers to fidelity. The PPAQ-2 is a psychometrically sound measure that can be used in future integrated care dismantling studies to identify provider behaviors that best predict patient outcomes.

Facilitators and Barriers to Seeking Mental Health Care Among Primary Care Veterans With Posttraumatic Stress Disorder.

Although posttraumatic stress disorder (PTSD) is common in primary care patients, many do not seek mental health treatment. Existing research on barriers and facilitators to receiving PTSD treatment are not specific to primary care patients. In this study, we sought to understand the psychosocial concerns, treatment barriers, and treatment facilitators among non-treatment-seeking primary care veterans with PTSD who reside in both rural and urban settings. Using a concurrent triangulation design, we collected qualitative focus group and quantitative self-report data concurrently, analyzed them separately, and merged the results for interpretation. In total, 27 veteran primary care patients with PTSD participated in 1 of 4 focus groups. A modified conventional content analysis approach was used. Team-based coding began with three broad primary codes (psychosocial concerns, barriers, and facilitators) and subcodes were allowed to emerge from the data. Self-report measures were used to collect clinical characteristics and barriers to care. The results expanded upon existing models of PTSD treatment initiation by (a) specifying treatment preferences, such as patient-centered care, peer support services, and open access scheduling, and (b) presenting concerns, such as anger and core symptoms of PTSD. Results also indicated that a commonly used quantitative barriers measure may offer an incomplete picture of why veterans do not seek treatment as it does not assess how past negative treatment experiences may affect utilization. Strategies to help veterans overcome barriers to care may benefit from a focus on negative treatment-seeking beliefs and tailoring based on a veteran's rural or urban status.

Enhancing implementation of measurement-based mental health care in primary care: a mixed-methods randomized effectiveness evaluation of implementation facilitation.

BACKGROUND: Mental health care lags behind other forms of medical care in its reliance on subjective clinician assessment. Although routine use of standardized patient-reported outcome measures, measurement-based care (MBC), can improve patient outcomes and engagement, clinician efficiency, and, collaboration across care team members, full implementation of this complex practice change can be challenging. This study seeks to understand whether and how an intensive facilitation strategy can be effective in supporting the implementation of MBC. Implementation researchers partnering with US Department of Veterans Affairs (VA) leaders are conducting the study within the context of a national initiative to support MBC implementation throughout VA mental health services. This study will focus specifically on VA Primary Care-Mental Health Integration (PCMHI) programs. METHODS: A mixed-methods, multiple case study design will include 12 PCMHI sites recruited from the 23 PCMHI programs that volunteered to participate in the VA national initiative. Guided by a study partnership panel, sites are clustered into similar groups using administrative metrics. Site pairs are recruited from within these groups. Within pairs, sites are randomized to the implementation facilitation strategy (external facilitation plus QI team) or standard VA national support. The implementation strategy provides an external facilitator and MBC experts who work with intervention sites to form a QI team, develop an implementation plan, and, identify and overcome barriers to implementation. The RE-AIM framework guides the evaluation of the implementation facilitation strategy which will utilize data from administrative, medical record, and primary qualitative and quantitative sources. Guided by the iPARIHS framework and using a mixed methods approach, we will also examine factors associated with implementation success. Finally, we will explore whether implementation of MBC increases primary care team communication and function related to the care of mental health conditions. DISCUSSION: MBC has significant potential to improve mental health care but it represents a major change in practice. Understanding factors that can support MBC implementation is essential to attaining its potential benefits and spreading these benefits across the health care system.

Mental health measurement among women veterans receiving co-located, collaborative care services.

Routine use of measurement to identify patient concerns and track treatment progress is critical to high quality patient care. This is particularly relevant to the Primary Care Behavioral Health model, where rapid symptom assessment and effective referral management are critical to sustaining population-based care. However, research suggests that women who receive treatment in co-located collaborative care settings utilizing the PCBH model are less likely to be assessed with standard measures than men in these settings. The current study utilized regional retrospective data obtained from the Veterans Health Administration's electronic medical record system to: (1) explore rates of mental health measurement for women receiving co-located collaborative care services (N = 1008); and (2) to identify predictors of mental health measurement in women veterans in these settings. Overall, only 8% of women had documentation of standard mental health measures. Measurement was predicted by diagnosis, facility size, length of care episode and care setting. Specifically, women diagnosed with depression were less likely than those with anxiety disorders to have standard mental health measurement documented. Several suggestions are offered to increase the quality of mental health care for women through regular use of measurement in integrated care settings.

Military veteran cancer survivors' preferences for a program to address lifestyle change and psychosocial wellness following treatment.

This study aimed to understand military veteran cancer survivors' preferences regarding the delivery of post-treatment wellness services. Thirty-three military veteran cancer survivors were interviewed about their perceptions of three models of health service delivery (home-, primary care-, and oncology-based services). Conventional qualitative content analysis revealed strengths and weaknesses of each service delivery model's content and structure (e.g., program location, inclusion of emotional support, access to clinical experts). All service delivery programs had strengths, with clinic-based programs offering the greatest breadth of services deemed important for wellness by cancer survivors.

Chiropractic Management for US Female Veterans With Low Back Pain: A Retrospective Study of Clinical Outcomes.

OBJECTIVE: The purpose of this study was to determine if female US veterans had clinically significant improvement in low back pain after chiropractic management. METHODS: This is a retrospective chart review of 70 courses of care for female veterans with a chief complaint of low back pain who received chiropractic management through the VA Western New York Healthcare System in Buffalo, New York. A paired t test was used to compare baseline and discharge outcomes for the Back Bournemouth Questionnaire. The minimum clinically important difference was set as a 30% improvement in the outcome measure from baseline to discharge. RESULTS: The average patient was 44.8 years old, overweight (body mass index 29.1 kg/m2), and white (86%). The mean number of chiropractic treatments was 7.9. Statistical significance was found for the Back Bournemouth Questionnaire outcomes. The mean raw score improvement was 12.4 points (P < .001), representing a 27.3% change from baseline with 47% of courses of care meeting or exceeding the minimum clinically important difference. CONCLUSION: For our sample of female veterans with low back pain, clinical outcomes from baseline to discharge improved under chiropractic care. Although further research is warranted, chiropractic care may be of value in contributing to the pain management needs of this unique patient population.

Measurement of Common Mental Health Conditions in VHA Co-located, Collaborative Care.

The VA has integrated psychologists and other licensed mental health providers, known collectively as co-located collaborative care (CCC) providers, into patients' primary care medical homes to improve mental health services for veterans. However, it is unclear if CCC providers are routinely using mental health measures as part of evidence-based, coordinated care. This study aimed to determine the prevalence and predictors of CCC provider utilization of brief, validated measures. A retrospective review of VA electronic medical records from 8403 veterans diagnosed with depression, posttraumatic stress disorder, or anxiety disorder was conducted. Results indicated that 23 % of the sample had a screening or brief symptom measure documented by a CCC provider. Likelihood of measurement was predicted by primary diagnosis, length of care episode, CCC provider credential, and clinic setting. Future research should address factors impacting measurement practices of CCC providers in order to develop implementation strategies for advancing measurement-based mental health care.

Moving toward integrated behavioral intervention for treating multimorbidity among chronic pain, depression, and substance-use disorders in primary care.

INTRODUCTION: The importance of using integrated treatment for multimorbidity has been increasingly recognized. One prevalent cluster of health conditions is multimorbidity of chronic pain, depression, and substance-use disorders, a common triad of illnesses among primary care patients. This brief report brings attention to an emerging treatment method of an integrated behavioral approach to improve health outcomes for individuals with these 3 conditions in the outpatient setting, particularly primary care. METHODS: A multidatabase search was conducted to identify studies of behavioral interventions targeting co-occurrence or multimorbidity among the 3 health conditions in the adult outpatient setting. An independent screening of the articles was accomplished by all authors with consensus on the final inclusion for review. RESULTS: Three studies met formal inclusion criteria for this review. The included studies evaluated cognitive behavioral therapy or combined motivational interviewing with cognitive behavioral therapy. Key findings from other reviews and additional studies are also included in this review to further inform the development of a common approach for treating this triad of conditions in primary care. CONCLUSIONS: Although there has been increased recognition for more effective and practical behavioral treatments for patients with multiple chronic health conditions, the evidence-base to inform practice remains limited. The findings from this review suggest that a common approach, rather than a distinct intervention for chronic pain, depression, or substance-use disorders, is indicated and that best care can be provided within the context of a coordinated, interdisciplinary, and patient-centered primary care team.

A program to improve detection of undiagnosed dementia in primary care and its association with healthcare utilization.

OBJECTIVE: Alzheimer's disease and related dementias are common and costly, with increased healthcare utilization for patients with these disorders. The current study describes a novel dementia detection program for veterans and examines whether program-eligible patients have higher healthcare utilization than age-matched comparison patients. DESIGN: Using a telephone-based case-finding approach, the detection program used risk factors available in the electronic medical record (EMR) and telephone-based brief cognitive screening. Holding illness severity constant, dementia detection and healthcare utilization were compared across age-matched groups with and without program risk factors. SETTING: Five Veterans Affairs Healthcare Network Upstate New York primary care clinics. PARTICIPANTS: Veterans aged 70 years and older. MEASUREMENTS: EMR data and the Charlson comorbidity index. RESULTS: Program-eligible patients (n = 5,333) demonstrated significantly greater levels of medical comorbidity relative to comparison patients and were on average more than twice as likely to be admitted to the hospital. They also had nearly double the number of outpatient visits to several services. Similar patterns were seen in those who screened positive on a brief cognitive measure, compared with those who screened negative. CONCLUSIONS: A novel program using EMR data to assist in the detection of newly diagnosed dementia in a clinical setting was found to be useful in identifying older veterans with multiple comorbid medical conditions and increased utilization of hospital and clinic services. Results suggest undetected cognitive impairment and dementia may significantly contribute to healthcare utilization and costs of care in older veterans.

Health service and medication use among veterans with persistent postconcussive symptoms.

Persistent postconcussive symptoms (PPCS) are noted when a series of cognitive, emotional, and somatosensory complaints persist for months after a concussion. Clinical management of PPCS can be challenging in the veteran population because of the nonspecific nature of symptoms and co-occurrence with affective disturbances such as posttraumatic stress disorder (PTSD) and chronic pain. In this study, we compared health service and medication use patterns in a sample of 421 veterans with PPCS with an age-matched cohort of case controls. The results suggest that the veterans with PPCS showed high rates of medical and mental health service utilization during a mean treatment period of 2 years. Although chronic pain commonly co-occurs with PPCS in veterans, service use and medication prescribing trends seem to have been influenced more by the presence of PTSD than chronic pain. Our findings reinforce the overlap among PPCS, PTSD, and chronic pain and demonstrate the complexity inherent in treating these conditions in veterans.

Exploratory Factor Analysis of a Patient-Facing PCBH Adherence Measure: The PPAQ-Patient.

Model adherence indicates the degree to which a program or intervention is delivered as intended. In integrated primary care, where mental health services are embedded into primary care clinics, appraisal of model adherence provides insight into whether these services align with key features of this unique practice environment (e.g., brief, interdisciplinary care). To date, such evaluations have emphasized system and provider factors. This study is a preliminary evaluation of whether a novel patient-facing measure, the Primary Care Behavioral Health Provider Adherence Questionnaire-Patient Version (PPAQ-Patient), can provide insight into adherence to the Primary Care Behavioral Health (PCBH) model of integrated primary care. Survey data were collected from 281 veterans who received PCBH care. Exploratory factor analyses evaluated the data structure. Results suggest that 19 items spanning three temporally-referenced subscales may feasibly capture patient perspectives on PCBH adherence at various stages of treatment. Future work is needed to refine the measure.

Brief behavioral intervention for chronic pain in integrated primary care: What are we waiting for?

Despite high rates of pain-related concerns among primary care patients and associated increases in health care costs (Gore et al., 2012; Mills et al., 2016), psychological or behavioral treatments that are well suited for use in integrated primary care (IPC) settings remain sparsely implemented. Psychological treatment for chronic pain has been recommended for many years (Darnall, 2021; Institute of Medicine (US) Committee on Advancing Pain Research, Care and Education, 2011; Kligler et al., 2018), and the emphasis on the application of nonpharmacological treatment has intensified following concerns about opioid safety. There is abundant empirical support for the use of psychological treatment for chronic pain, such as cognitive behavioral therapy (CBT) in specialty settings (Williams et al., 2021). The evidence to support the use of "brief treatments" in IPC is in a comparatively early stage. The limited state of the research might suggest that brief behavioral intervention for chronic pain is years away from being ready for translation to everyday clinical practice. But why wait? We therefore conducted a focused narrative review of peer-reviewed research on brief psychotherapy for chronic pain in adults that could be feasibly employed in IPC settings through more widely adopted models, such as primary care behavioral health.

Pain and Hazardous Alcohol Use in Veterans in Primary Care: The Role of Affective Pain Interference and Alcohol Pain-Coping Perceptions.

Chronic pain and unhealthy alcohol use commonly co-occur and are associated with negative health outcomes. Veterans may be particularly vulnerable to these conditions, yet limited research has examined factors involved in their co-occurrence. This cross-sectional study aimed to examine the role of affective pain interference and alcohol pain-coping perceptions in the relationship between pain and hazardous alcohol use. As informed by the catastrophizing, anxiety, negative urgency, and expectancy model, we hypothesized that the relationship between pain and hazardous alcohol consumption is mediated by affective pain interference and stronger among those with greater perceptions that alcohol helps cope with pain. Participants were 254 VA primary care patients (87.8% male, Mage = 64.03, 76.4% White) with a history of chronic musculoskeletal pain, past-year alcohol use, and past-week pain. Veterans completed a mailed survey including measures of pain, affective pain interference, alcohol pain-coping perceptions, and hazardous alcohol use. Hypotheses were tested with regression models and PROCESS macros. As hypothesized, affective pain interference mediated the pain-hazardous alcohol use association. Contrary to hypotheses, results showed no moderating effect of alcohol pain-coping perceptions. Findings partially support relationships among theorized constructs and suggest that for Veterans with co-occurring pain and alcohol use it may be important to target pain-related affective interference and perceptions that alcohol helps cope with pain. PERSPECTIVE: This article presents a test of factors involved in the pain and alcohol relationship, as informed by the CANUE model. Findings suggest that for Veterans with co-occurring pain and past-year alcohol use, it may be important to target pain-related affective interference and perceptions that alcohol helps cope with pain.

Primary care utilization among veterans with chronic musculoskeletal pain: a retrospective chart review.

OBJECTIVE: Patients with chronic pain have been shown to be more frequent utilizers of primary care, a contributor to increased health care costs. This study aimed to clarify which patient factors predict primary care utilization among veterans with chronic pain. DESIGN: Data were gathered from the electronic medical records of veterans who used Veterans Affairs primary care services from 2003 to 2009 in upstate New York. Chronic pain cases (N = 792) were those veterans diagnosed with a musculoskeletal condition of the hip, knee, or lower back during two or more primary care encounters over a period ≥ 3 months. Cases were frequency matched by age to controls, or those veterans who did not have a chronic musculoskeletal condition of the hip, knee, or lower back. Demographic information, medical and psychiatric diagnoses, medication use, and other health-related factors were used in regression models to predict primary care utilization. RESULTS: Cases consistently accrued more primary care encounters than controls during each year of the observation period. Cases also accrued more encounters from specialty medicine clinics, chronic pain clinics, and behavioral health clinics co-located in primary care. The contribution of mental health factors to care utilization differed by case-control status. Diagnosis of depression and substance use disorders were predictors of care utilization only among controls, whereas anxiety disorders, use of anxiolytics, and adjustment disorders were predictors only among cases. Cases with a co-occurring anxiety disorder had a greater than twofold increased risk (odds ratio = 2.36, 95% confidence interval = 1.32-4.22) of being in the top 10% of the distribution of total primary care utilization. CONCLUSIONS: Mental health conditions that commonly co-occur with chronic musculoskeletal pain contribute to greater health care utilization. Improved screening and early intervention for these disorders in primary care may improve patient outcomes and stem high rates of care utilization of veterans.
