Little is known about mental health services utilization among Iraq and Afghanistan veterans receiving care at Department of Veterans Affairs (VA) facilities. Of 49,425 veterans with newly diagnosed posttraumatic stress disorder (PTSD), only 9.5% attended 9 or more VA mental health sessions in 15 weeks or less in the first year of diagnosis. In addition, engagement in 9 or more VA treatment sessions for PTSD within 15 weeks varied by predisposing variables (age and gender), enabling variables (clinic of first mental health diagnosis and distance from VA facility), and need (type and complexity of mental health diagnoses). Thus, only a minority of Iraq and Afghanistan veterans with new PTSD diagnoses received a recommended number and intensity of VA mental health treatment sessions within the first year of diagnosis.

We sought to investigate longitudinal trends and risk factors for mental health diagnoses among Iraq and Afghanistan veterans. We determined the prevalence and predictors of mental health diagnoses among 289,328 Iraq and Afghanistan veterans entering Veterans Affairs (VA) health care from 2002 to 2008 using national VA data. Of 289,328 Iraq and Afghanistan veterans, 106,726 (36.9%) received mental health diagnoses; 62,929 (21.8%) were diagnosed with posttraumatic stress disorder (PTSD) and 50 432 (17.4%) with depression. Adjusted 2-year prevalence rates of PTSD increased 4 to 7 times after the invasion of Iraq. Active duty veterans younger than 25 years had higher rates of PTSD and alcohol and drug use disorder diagnoses compared with active duty veterans older than 40 years (adjusted relative risk = 2.0 and 4.9, respectively). Women were at higher risk for depression than were men, but men had over twice the risk for drug use disorders. Greater combat exposure was associated with higher risk for PTSD. Mental health diagnoses increased substantially after the start of the Iraq War among specific subgroups of returned veterans entering VA health care. Early targeted interventions may prevent chronic mental illness.

Background: A significant burden of illness associated with the mental health effects of Operation Enduring Freedom (OEF) in Afghanistan and Operation Iraqi Freedom (OIF) in Iraq is now a key focus of the Veteran Health Administration (VHA). The issue of sexual trauma has received scant attention in the discussion of deployment-related stressors and subsequent mental health conditions, but it has been hypothesized to be a significant mental health issue for this newest generation of veterans. To date, no research has examined the contribution of experiences of sexual assault or harassment during service, referred to as Military Sexual Trauma (MST), to mental health conditions among OEF/OIF veterans. Purpose: To examine the mental health conditions associated with MST among OEF/OIF veterans treated in VHA. Methods: This cross-sectional analysis utilized administrative data obtained from the VA/DoD OEF/OIF Roster and VHA inpatient and outpatient event files. Analyses include 89,960 OEF/OIF veteran patients who utilized medical care at any VHA facility during the time period October 1, 2001 to October 1, 2006 and for whom MST screening data were available. Diagnoses were quantified by grouping ICD-9 codes into non-overlapping categories using the Mental Health and Substance Abuse Clinical Classification System. We assessed bivariate associations between demographic characteristics and MST status, and calculated the adjusted odds of mental health conditions in relation to MST status. Results were stratified by gender. Results: MST was reported by 14.5% (1,849) of women and 0.6% (471) of men. Both women and men with a positive MST screen were three times more likely to be diagnosed with a mental health condition than patients who did not report MST. The most frequently reported mental health conditions among OEF/OIF veterans were depression, PTSD, anxiety disorders, adjustment disorders, and substance abuse disorders, all of which were significantly more likely among women and men who experienced MST. The relationship between MST and specific mental health conditions did not differ by gender with the exception of PTSD, where women who had experienced MST were significantly more likely to have PTSD than men who experienced MST. Conclusions: A substantial proportion of OEF/OIF veterans treated at VHA reported MST and these experiences are associated with a wide range of mental health conditions. VHA should ensure access to appropriate services for newly returned veterans and clinician training regarding sexual trauma in men and women. MST appears to be a particularly salient issue for the treatment of PTSD among women.

In response to growing concerns about sexual violence as an underrecognized traumatic consequence of military service, Veterans Health Administration policy requires universal screening for sexual trauma sustained during military service. This prospective study, the first to evaluate national efforts to screen for military sexual trauma, investigated whether sexual trauma screening is associated with increased utilization of mental health services. This study examined data for all male (N=540,381) and female (N=33,259) veterans who had valid responses to screens for military sexual trauma in 2005. The use of mental health services during the three months after screening was examined for persons who screened positive for military sexual trauma and for those who screened negative. Findings were stratified by use of mental health services in the six months before the screening. Compared with negative screens, positive screens were associated with significantly increased rates of postscreen mental health treatment. A more than twofold increase was observed for patients without previous use of mental health treatment (women: relative risk [RR]=2.52, 95% confidence interval [CI]= 2.38-2.66; men: RR=2.47, 95% CI=2.34-2.61). In this group, the number of positive screens needed for one additional patient to access treatment was 5.5 for women and 7.2 for men. Our findings suggest that detection via screening is associated with increased rates of mental health treatment. An effective screening program that promotes detection of sexual trauma and access to mental health care can help to reduce the burden of psychiatric illness for those who have experienced military sexual trauma.

We sought to evaluate outcomes of the Veterans Administration (VA) Afghan and Iraq Post-Deployment Screen for mental health symptoms. Veterans Administration clinicians were encouraged to refer Iraq or Afghanistan veterans who screened positive for posttraumatic stress disorder, depression, or high-risk alcohol use to a VA mental health clinic. Multivariate methods were used to determine predictors of screening, the proportions who screened positive for particular mental health problems, and predictors of VA mental health clinic attendance. Among 750 Iraq and Afghanistan veterans who were referred to a VA medical center and 5 associated community clinics, 338 underwent postdeployment screening; 233 (69%) screened positive for mental health problems. Having been seen in primary care (adjusted odd ratio [AOR]=13.3; 95% confidence interval [CI]=8.31, 21.3) and at a VA community clinic (AOR=3.28; 95% CI=2.03, 5.28) predicted screening. African American veterans were less likely to have been screened than were White veterans (AOR=0.45; 95% CI=0.22, 0.91). Of 233 veterans who screened positive, 170 (73%) completed a mental health follow-up visit. A substantial proportion of veterans met screening criteria for co-occurring mental health problems, suggesting that the VA screens may help overcome a "don't ask, don't tell" climate that surrounds stigmatized mental illness. Based on data from 1 VA facility, VA postdeployment screening increases mental health clinic attendance among Iraq and Afghanistan veterans.

We examined the utility of the Veterans Health Administration (VHA) universal screening program for military sexual violence. We analyzed VHA administrative data for 185,880 women and 4139888 men who were veteran outpatients and were treated in VHA health care settings nationwide during 2003. Screening was completed for 70% of patients. Positive screens were associated with greater odds of virtually all categories of mental health comorbidities, including posttraumatic stress disorder (adjusted odds ratio [AOR]=8.83; 99% confidence interval [CI] = 8.34, 9.35 for women; AOR = 3.00; 99% CI = 2.89, 3.12 for men). Associations with medical comorbidities (e.g., chronic pulmonary disease, liver disease, and for women, weight conditions) were also observed. Significant gender differences emerged. The VHA policies regarding military sexual trauma represent a uniquely comprehensive health care response to sexual trauma. Results attest to the feasibility of universal screening, which yields clinically significant information with particular relevance to mental health and behavioral health treatment. Women's health literature regarding sexual trauma will be particularly important to inform health care services for both male and female veterans.

Posttraumatic stress disorder (PTSD) is associated with objective health problems in specific populations, such as Vietnam veterans. Less is known about PTSD and health among medical samples, especially PTSD patients with different etiologic traumas. This study examined PTSD and health in medical patients within the Department of Veterans Affairs healthcare system. A total of 134 patients completed an interview and questionnaires. Data on physician-diagnosed illnesses were gathered from medical records. PTSD diagnosis and symptoms were associated with a higher likelihood of circulatory and musculoskeletal disorders. In addition, PTSD symptoms were associated with more medical conditions. PTSD symptoms and diagnoses were also associated with poorer health related quality of life. Most of these findings remained significant after controlling for comorbid depressive, generalized anxiety disorder, and panic attack symptoms. Overall, gender did not moderate the relationship between PTSD and poorer health.

The Department of Veterans Affairs (VA) has a Congressional mandate but few empirical data on which to design and improve national health care services for women. We examined characteristics associated with women's current, former and non-use of the VA health care system. The study included 1,500 female veterans sampled from the Department of Veterans Affairs National Registry of Women Veterans. Women completed a 45-minute telephone survey assessing multiple domains of functional status and health service use. Using multivariate logistic regression, use of VA health care was associated with older age, more education, not being married, lower rates of insurance coverage, and poorer physical and psychological health. Women who were former users of VA health care were more likely to be ethnic minorities, have children, served less time in the military, had higher rates of insurance coverage and better physical and psychological health than current users. Prominent military experiences (e.g., service in a war-zone, exposure to trauma) were associated with former use and never using the VA health care system. Women who use VA health care are at greater economic, social, and health risk than nonusers, factors that have personal implications for the veteran as well as cost and service implications for VA. Additional research is needed to better understand the role of military experiences in women veterans' choice of health care.
