Integration of Health Coaches in a Whole Health Team Model of Chronic Pain Care: a Qualitative Study.

OBJECTIVE: Health coaching has shown promise in helping patients manage their chronic disease and in improving health outcomes, yet the implementation of health coaching in healthcare systems is understudied. Further, evidence suggests that interdisciplinary care teams may be more effective in treating chronic pain than usual care. As such, we sought to examine the benefits and drawbacks to embedding health coaches within interdisciplinary pain care teams ("Whole Health Teams"). DESIGN: As part of a multisite clinical trial (at five Veterans Health Administration sites) investigating the effectiveness of a Whole Health Team (WHT) approach to care for patients with chronic pain, qualitative interviews gathered data on how the experience of treating patients in the WHT differed from the experience treating patients outside the WHT, as well as provider experiences coordinating patient care within the WHT. PARTICIPANTS: Twenty-two WHT members, study investigators, and study coordinators. APPROACH: Data were analyzed using a rapid analysis approach. RESULTS: Overall, stakeholders perceived considerable synergy within the interdisciplinary pain care team. Each provider brought a different perspective to the patient's health concerns, which stakeholders felt was valuable and increased patient progress towards goals. The team model was also viewed as efficient because everyone was committed to working together and communicating as a team. Logistically, however, stakeholders noted challenges to working as a team, especially regarding patient goal setting. Furthermore, multiple stakeholders believed the care team model required a high degree of dedication to teamwork and communication among its members to be successful. CONCLUSIONS: Embedding health coaches within interdisciplinary pain care teams may improve care processes and accelerate patient progress. Successful implementation would require adequate training, role clarification, and expectation setting to facilitate good communication across all care team members. Additional research is needed to evaluate the clinical outcomes of integrating health coaches on WHTs versus other implementation approaches.

Evidence of Hippocampal Structural Alterations in Gulf War Veterans With Predicted Exposure to the Khamisiyah Plume.

OBJECTIVES: To replicate and expand our previous findings of smaller hippocampal volumes in Gulf War (GW) veterans with predicted exposure to the Khamisiyah plume. METHODS: Total hippocampal and hippocampal subfield volumes were quantified from 3 Tesla magnetic resonance images in 113 GW veterans, 62 of whom had predicted exposure as per the Department of Defense exposure models. RESULTS: Veterans with predicted exposure had smaller total hippocampal and CA3/dentate gyrus volumes compared with unexposed veterans, even after accounting for potentially confounding genetic and clinical variables. Among veterans with predicted exposure, memory performance was positively correlated with hippocampal volume and negatively correlated with estimated exposure levels and self-reported memory difficulties. CONCLUSIONS: These results replicate and extend our previous finding that low-level exposure to chemical nerve agents from the Khamisiyah pit demolition has detrimental, lasting effects on brain structure and function.

Insomnia Severity, Subjective Sleep Quality, and Risk for Obstructive Sleep Apnea in Veterans With Gulf War Illness.

Despite the fact that sleep disturbances are common in veterans with Gulf War Illness (GWI), there has been a paucity of published sleep studies in this veteran population to date. Therefore, the present study examined subjective sleep quality (assessed with the Pittsburgh Sleep Quality Index), insomnia severity (assessed with the Insomnia Severity Index), and risk for obstructive sleep apnea (assessed with the STOP questionnaire) in 98 Gulf War veterans. Veterans with GWI, defined either by the Kansas or Centers for Disease Control and Prevention criteria, had greater risk for obstructive sleep apnea (i.e., higher STOP scores) than veterans without GWI. This difference persisted even after accounting for potentially confounding demographic (e.g., age, gender) and clinical variables. Veterans with GWI, defined by either the Kansas or Centers for Disease Control and Prevention criteria, also had significantly greater insomnia severity and poorer sleep quality than veterans without GWI (p < 0.05), even after accounting for potentially confounding variables. Furthermore, there were significant, positive correlations between insomnia severity, subjective sleep quality, and GWI symptom severity (p ≤ 0.01). In stepwise linear regression models, insomnia severity significantly predicted GWI status over and above demographic and clinical variables. Together these findings provide good rationale for treating sleep disturbances in the management of GWI.

Associations between the self-reported frequency of hearing chemical alarms in theater and regional brain volume in Gulf War Veterans.

BACKGROUND: We previously reported evidence of reduced cortical gray matter (GM), white matter (WM), and hippocampal volume in Gulf War (GW) veterans with predicted exposure to low-levels of nerve agent according to the 2000 Khamisiyah plume model analysis. Because there is suggestive evidence that other nerve agent exposures may have occurred during the Gulf War, we examined the association between the self-reported frequency of hearing chemical alarms sound during deployment in the Gulf War and regional brain volume in GW veterans. METHODS: Ninety consecutive GW veterans (15 female, mean age: 52±8years) participating in a VA-funded study underwent structural magnetic resonance imaging (MRI) on a 3T scanner. Freesurfer (version 5.1) was used to obtain regional measures of cortical GM, WM, hippocampal, and insula volume. Multiple linear regression was used to determine the association between the self-reported frequencies of hearing chemical alarms during the Gulf War and regional brain volume. RESULTS: There was an inverse association between the self-reported frequency of hearing chemical alarms sound and total cortical GM (adjusted p=0.007), even after accounting for potentially confounding demographic and clinical variables, the veterans' current health status, and other concurrent deployment-related exposures that were correlated with hearing chemical alarms. Post-hoc analyses extended the inverse relationship between the frequency of hearing chemical alarms to GM volume in the frontal (adjusted p=0.02), parietal (adjusted p=0.01), and occipital (adjusted p=0.001) lobes. In contrast, regional brain volumes were not significantly associated with predicted exposure to the Khamisiyah plume or with Gulf War Illness status defined by the Kansas or Centers for Disease Control and Prevention criteria. CONCLUSIONS: Many veterans reported hearing chemical alarms sound during the Gulf War. The current findings suggest that exposure to substances that triggered those chemical alarms during the Gulf War likely had adverse neuroanatomical effects.
