The Veterans Health Administration (VHA) offers spiritual supports to Veterans nationally through its Chaplaincy Service and its Whole Health initiative. There are no systematic efforts to extend spiritual supports to Veterans re-entering community post-incarceration, however. Thus, the full potential of spiritual supports in bolstering well-being and minimizing recidivism during re-entry may not be fully realized.

Sleep disturbances, including chronic insomnia and sleep apnea, are major concerns for US veterans, with rising rates and detrimental effects on physical, mental, and social well-being. Sleep disturbances in veterans are also underdiagnosed and undertreated for reasons that include limited sleep clinician availability, long wait times, and the time commitment for treatment. Greater use of sleep health information technologies could improve access to assessment and treatment of sleep disturbances.

Importance: Few evidence-based treatments are available for Gulf War illness (GWI). Behavioral treatments that target factors known to maintain the disability from GWI, such as problem-solving impairment, may be beneficial. Problem-solving treatment (PST) targets problem-solving impairment and is an evidence-based treatment for other conditions.

Background: The transition to the community after incarceration presents challenges for returning citizens, including the immediate need to secure housing, employment, and income. Additionally, health care is essential for this population due to high rates of chronic physical health and mental health problems and substance use disorders. There is growing recognition of the need for interventions that support returning citizens as they navigate community reintegration while simultaneously tending to physical and behavioral health needs.

Healthcare must rapidly and systematically learn from earlier COVID-19 responses to prepare for future crises. This is critical for VA's Mental Health Residential Rehabilitation and Treatment Programs (RRTPs), offering 24/7 care to Veterans for behavioral health and/or homelessness. We adapted the World Health Organization's After Action Review (AAR) to conduct semi-structured small-group discussions with staff from two RRTPs and Veterans who received RRTP care during COVID-19, to examine COVID-19's impact on these programs.

Background: Insomnia is a prevalent and debilitating disorder among veterans. Cognitive behavioral therapy for insomnia (CBTI) can be effective for treating insomnia, although many cannot access this care. Technology-based solutions and lifestyle changes, such as physical activity (PA), offer affordable and accessible self-management alternatives to in-person CBTI.

Identifying an intervention's core components is indispensable to gauging whether an intervention is implemented with fidelity and/or is modified; it is often a multi-stage process, starting with the first stage of identifying an initial set of core components that are gradually refined. This first stage of identifying initial core components has not been thoroughly examined. Without a clear set of steps to follow, interventions may vary in the rigor and thought applied to identifying their initial core components.

Military veterans involved in the criminal justice system are a vulnerable subpopulation that has extensive physical and behavioural health treatment needs. Like non-veteran populations, safe and stable housing, employment and social support are critical for veterans returning to society after incarceration. The challenges of social reintegration are immense, and the risk of recidivism is high.

Background: Between 12,000 and 16,000 veterans leave incarceration annually. As is known to be the case for justice-involved populations in general, mental health disorders (MHDs) and substance use disorders (SUDs) are highly prevalent among incarcerated veterans, and individuals with MHDs and SUDs reentering the community are at increased risk of deteriorating health and recidivism. We sought to identify opportunities to better coordinate care/services across correctional, community, and VA systems for reentry veterans with MHDs and SUDs.

Article Synopsis
  • The study analyzed secure messaging (SM) communication between patients and primary care teams at two VA facilities, focusing on message threads.
  • Most messages (94.5%) were initiated by patients (90.4%), primarily addressing medication renewals, scheduling, and health issues, while only a small percentage (5.5%) came from healthcare teams.
  • A significant number of issues (24.2%) were unresolved through SM, indicating that improvements in communication training for both patients and providers could enhance the overall interaction and resolution of concerns.
