Patterns of conventional and complementary non-pharmacological health practice use by US military veterans: a cross-sectional latent class analysis

Implications of Physical Activity in Reducing Alcohol Use for Women Veterans: A Narrative Review

Women veterans (WV) are a fast-growing population in the United States with concerning health disparities. Reports of increased risks of cardiovascular disease (CVD) and poorer health are evident in WV compared with their civilian counterparts. The transition from active duty to veteran poses additional life stressors, causing changes in health behaviors such as unhealthy alcohol consumption and decreased physical activity, which may explain health disparities in WV. The changes in these two health risk behaviors may be influenced by each other, and emerging evidence suggests that physical activity aids in managing alcohol consumption during alcohol use treatment. In this general narrative review, we summarized findings from studies involving WV on (1) the associations between alcohol consumption and physical activity and (2) the effect of physical activity on reducing alcohol use. We also discussed the clinical consideration of adding physical activity to alcohol use interventions for WV. Most of the literature included in this review has been based on predominantly veteran men populations. This knowledge gap highlights the importance of continued efforts and research studies targeting WV to eliminate health disparities among them.

Complementary and Integrative Medicine Prevalence and Utilization in International Military and Veteran Settings and Communities: A Systematic Review

INTRODUCTION

Active duty military personnel and veterans have unique and complex health needs, with the high demands of military life often leading to chronic physical and mental health conditions. Complementary and integrative medicine (CIM) could be a possible solution to this problem. Some military health systems have started integrating CIM into health care delivery. However, there has been no systematic evaluation of the prevalence and utilization of CIM in military and veteran populations globally.

MATERIALS AND METHODS

A Preferred Reporting Items For Systematic Reviews and Meta-Analysis Protocols protocol was used to systematically search for original research assessing the prevalence and utilization of CIM among active serving military or veterans. CINAHL, MEDLINE, Scopus, and AMED databases were searched up to February 3, 2023.

RESULTS

A total of 27 studies met the inclusion criteria and were included in this review. The overall quality of evidence was high with a low risk of bias. Utilization of CIM varied. The lowest utilization demonstrated that only 1.9% of services delivered by military health system were CIM. The majority of studies found utilization rates between 30% and 80%, with some studies reporting use as high as 90%. The most commonly used CIM therapies included chiropractic care, massage, mindfulness/meditation, and acupuncture. Utilization of CIM products was high and ranged from 32% to 87%. The most frequently used products were dietary supplements, particularly multivitamins and minerals and protein supplements/amino acids. The use of herbal products was high among veterans ranging from 10% to 79%.

CONCLUSIONS

The high demand for CIM by military personnel and veterans has important implications for policy, funding allocation, and integration of these services into clinical practice, particularly by countries not currently doing so. Further research is needed to assess the implementation of CIM into real-world settings to explore barriers and facilitators for their use in clinical practice and, by extension, their integration into the wider health care system.

Design, methods, and recruitment outcomes of the Veterans' Pain Care Organizational Improvement Comparative Effectiveness (VOICE) study

The Veterans' Pain Care Organizational Improvement Comparative Effectiveness (VOICE) study is a 12-month pragmatic randomized comparative effectiveness trial conducted at ten United States Veterans Affairs (VA) health care sites. The overall goal was to test interventions to improve pain while reducing opioid use among VA patients with moderate-severe chronic pain despite treatment with long-term opioid therapy (LTOT). Aims were 1) to compare lower-intensity telecare collaborative pain management (TCM) versus higher-intensity integrated pain team management (IPT), and 2) to test the option of switching to buprenorphine (versus no option) in a high-dose subgroup. Recruitment challenges included secular trends in opioid prescribing and the COVID-19 pandemic. Participants were recruited over 3.5 years. Of 6966 potentially eligible patients, 4731 (67.9%) were contacted for telephone eligibility interview; of those contacted, 3398 (71.8%) declined participation, 359 (7.6%) were ineligible, 821 (24.2%) enrolled, and 820 (24.1%) were randomized. The most common reason for declining was satisfaction with pain care (n = 731). The most common reason for ineligibility was not having moderate-severe chronic pain (n = 110). Compared with the potentially eligible population, randomized participants were slightly younger, more often female, had similar prescribed opioids, and had similar or higher rates of pain and mental health diagnoses. The enrolled patient number was lower than the original target, but sufficient to power planned analyses. In conclusion, the VOICE trial enrolled a diverse sample similar to the population of VA patients receiving LTOT. Results will add substantially to limited existing evidence for interventions to improve pain while reducing opioid use. ClinicalTrials.gov identifier: NCT03026790.

The relationship between capacity and utilization of nonpharmacologic therapies in the US Military Health System

Background

Nonpharmacologic therapies (NPTs) are recommended as first-line treatments for pain, however the impact of expanding professional capacity to deliver these therapies on use has not been extensively studied. We sought to examine whether an effort by the US Military Health System (MHS) to improve access to NPTs by expanding professional capacity increased NPT utilization in a cohort at higher risk for pain – Army soldiers returning from deployment.

Methods

Our study involved secondary analysis of MHS workforce data derived from the Defense Medical Human Resources System Internet (DMHRSi), and healthcare utilization data obtained from two ambulatory record systems of the Military Health System (MHS) for a sample of 863,855 Army soldiers previously deployed to Iraq or Afghanistan over a 10-year period (2008–2017). We measured clinical provider capacity in three occupational groups responsible for pain management at 130 military treatment facilities (MTFs): physical therapy, chiropractic, and behavioral health, measured annually as full-time equivalence per 100,000 patients served at each MTF. Utilization in both direct and purchased care settings was measured as annual mean NPT users per 1000 sample members and mean encounters per NPT user. Generalized estimating equation models estimated the associations of facility-level occupational capacity measures and facility-level utilization NPT measures.

Results

In 2008, nearly all MTFs had some physical therapist and behavioral health provider capacity, but less than half had any chiropractor capacity. The largest increase in capacity from 2008 to 2017 was for chiropractors (89%) followed by behavioral health providers (77%) and physical therapists (37%). Models indicated that increased capacity of physical therapists and chiropractors were associated with significantly increased utilization of six out of seven NPTs. Acupuncture initiation was associated with capacity increases in each occupation. Increased professional capacity in MTFs was associated with limited but positive effects on NPT utilization in purchased care.

Conclusions

Increasing occupational capacity in three professions responsible for delivering NPTs at MTFs were associated with growing utilization of seven NPTs in this Army sample. Despite increasing capacity in MTFs, some positive associations between MTF capacity and purchased care utilization suggest an unmet need for NPTs. Future research should examine if these changes lead to greater receipt of guideline-concordant pain management.

Care Outcomes for Chiropractic Outpatient Veterans (COCOV): a qualitative study with veteran stakeholders from a pilot trial of multimodal chiropractic care

BACKGROUND

Low back pain (LBP) is common among military veterans seeking treatment in Department of Veterans Affairs (VA) healthcare facilities. As chiropractic services within VA expand, well-designed pragmatic trials and implementation studies are needed to assess clinical effectiveness and program uptake. This study evaluated veteran stakeholder perceptions of the feasibility and acceptability of care delivery and research processes in a pilot trial of multimodal chiropractic care for chronic LBP.

METHODS

The qualitative study was completed within a mixed-method, single-arm, pragmatic, pilot clinical trial of chiropractic care for LBP conducted in VA chiropractic clinics. Study coordinators completed semi-structured, in person or telephone interviews with veterans near the end of the 10-week trial. Interviews were audiorecorded and transcribed verbatim. Qualitative content analysis using a directed approach explored salient themes related to trial implementation and delivery of chiropractic services.

RESULTS

Of 40 participants, 24 completed interviews (60% response; 67% male gender; mean age 51.7 years). Overall, participants considered the trial protocol and procedures feasible and reported that the chiropractic care and recruitment methods were acceptable. Findings were organized into 4 domains, 10 themes, and 21 subthemes. Chiropractic service delivery domain encompassed 3 themes/8 subthemes: scheduling process (limited clinic hours, scheduling future appointments, attendance barriers); treatment frequency (treatment sufficient for LBP complaint, more/less frequent treatments); and chiropractic clinic considerations (hire more chiropractors, including female chiropractors; chiropractic clinic environment; patient-centered treatment visits). Outcome measures domain comprised 3 themes/4 subthemes: questionnaire burden (low burden vs. time-consuming or repetitive); relevance (items relevant for LBP study); and timing and individualization of measures (questionnaire timing relative to symptoms, personalized approach to outcomes measures). The online data collection domain included 2 themes/4 subthemes: user concerns (little difficulty vs. form challenges, required computer skills); and technology issues (computer/internet access, junk mail). Clinical trial planning domain included 2 themes/5 subthemes: participant recruitment (altruistic service by veterans, awareness of chiropractic availability, financial compensation); and communication methods (preferences, potential barriers).

CONCLUSIONS

This qualitative study highlighted veteran stakeholders' perceptions of VA-based chiropractic services and offered important suggestions for conducting a full-scale, veteran-focused, randomized trial of multimodal chiropractic care for chronic LBP in this clinical setting.

Complementary, Integrative, and Nondrug Therapy Use for Pain Among US Military Veterans on Long-term Opioids

BACKGROUND

Long-term opioid therapy for chronic pain arose amid limited availability and awareness of other pain therapies. Although many complementary and integrative health (CIH) and nondrug therapies are effective for chronic pain, little is known about CIH/nondrug therapy use patterns among people prescribed opioid analgesics.

OBJECTIVE

The objective of this study was to estimate patterns and predictors of self-reported CIH/nondrug therapy use for chronic pain within a representative national sample of US military veterans prescribed long-term opioids for chronic pain.

RESEARCH DESIGN

National two-stage stratified random sample survey combined with electronic medical record data. Data were analyzed using logistic regressions and latent class analysis.

SUBJECTS

US military veterans in Veterans Affairs (VA) primary care who received ≥6 months of opioid analgesics.

MEASURES

Self-reported use of each of 10 CIH/nondrug therapies to treat or cope with chronic pain in the past year: meditation/mindfulness, relaxation, psychotherapy, yoga, t'ai chi, aerobic exercise, stretching/strengthening, acupuncture, chiropractic, massage; Brief Pain Inventory-Interference (BPI-I) scale as a measure of pain-related function.

RESULTS

In total, 8891 (65%) of 13,660 invitees completed the questionnaire. Eighty percent of veterans reported past-year use of at least 1 nondrug therapy for pain. Younger age and female sex were associated with the use of most nondrug therapies. Higher pain interference was associated with lower use of exercise/movement therapies. Nondrug therapy use patterns reflected functional categories (psychological/behavioral, exercise/movement, manual).

CONCLUSIONS

Use of CIH/nondrug therapies for pain was common among patients receiving long-term opioids. Future analyses will examine nondrug therapy use in relation to pain and quality of life outcomes over time.

Yoga Practice Among Veterans With and Without Chronic Pain: A Mixed Methods Study

OBJECTIVES

The primary aim of this study was to examine differences in yoga practice between persons with and without chronic pain. Secondarily, we describe use of the Essential Properties of Yoga Questionnaire, Short Form (EPYQ-SF) for self-report.

DESIGN

Participants were members of an existing cohort of veterans who completed a 2015-2016 survey focused on pain and nonpharmacological health practices. Cohort members who reported yoga in the past year [n=174 (9.4%) of 1850] were eligible for the present study, which used multiple-contact mixed-mode survey methodology to collect data on yoga practices. The EPYQ-SF was used to assess properties and context of yoga practice. Practice patterns were compared for participants with and without chronic pain. To explore potential reasons for reported yoga practice patterns, focused semistructured interviews were conducted with a subset of participants.

RESULTS

Of 174 participants contacted, 141 (82%) returned the yoga questionnaire and 110 (78% of respondents) were still practicing yoga. Among yoga practitioners, 41 (37%) had chronic pain. Practitioners with chronic pain reported gentler (2.8 vs. 3.1, 5-point scale) and less active (2.9 vs. 3.3) yoga practice than those without. Those with chronic pain attended yoga studios less frequently and reported shorter yoga practices than those without. Most yoga practice was self-directed and at home.

CONCLUSIONS

Differences in yoga practice of persons with and without chronic pain have implications for implementation of yoga interventions for chronic pain. Future interventions should focus on alternative individual delivery formats or addressing barriers to group practice among people with chronic pain.
