VA mental health services utilization in Iraq and Afghanistan veterans in the first year of receiving new mental health diagnoses

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.

Association of Mental Health Disorders With Prescription Opioids and High-Risk Opioid Use in US Veterans of Iraq and Afghanistan

CONTEXT Record numbers of Iraq and Afghanistan veterans survive their war injuries and yet continue to experience pain and mental health problems, particularly posttraumatic stress disorder (PTSD). Little is known about the association of mental health disorders and prescription opioid use. OBJECTIVE To investigate the effect of mental health disorders, particularly PTSD, on risks and adverse clinical outcomes associated with prescription opioid use. DESIGN Retrospective cohort study involving 141,029 Iraq and Afghanistan veterans who received at least 1 non-cancer-related pain diagnosis within 1 year of entering the Department of Veterans Affairs (VA) health care system from October 1, 2005, through December 31, 2010. MAIN OUTCOME MEASURES Independent association of mental health disorders and the prescription of opioids, higher risk opioid use, and adverse clinical outcomes (eg, accidents and overdose) within 1 year of receiving a pain-related diagnosis. RESULTS A total of 15,676 veterans were prescribed opioids within 1 year of their initial pain diagnosis. Compared with 6.5% of veterans without mental health disorders, 17.8% (adjusted relative risk [RR], 2.58; 95% CI, 2.49-2.67) of veterans with PTSD and 11.7% (adjusted RR, 1.74; 95% CI, 1.67-1.82) with other mental health diagnoses but without PTSD were significantly more likely to receive opioids for pain diagnoses. Of those who were prescribed pain medication, veterans with PTSD were more likely than those without mental health disorders to receive higher-dose opioids (22.7% vs 15.9%, adjusted RR, 1.42; 95% CI, 1.31-1.54), receive 2 or more opioids concurrently (19.8% vs 10.7%, adjusted RR, 1.87; 95% CI, 1.70-2.06), receive sedative hypnotics concurrently (40.7% vs 7.6%, adjusted RR, 5.46; 95% CI, 4.91-6.07), or obtain early opioid refills (33.8% vs 20.4%; adjusted RR, 1.64; 95% CI, 1.53-1.75). Receiving prescription opioids (vs not) was associated with an increased risk of adverse clinical outcomes for all veterans (9.5% vs 4.1%; RR, 2.33; 95% CI, 2.20-2.46), which was most pronounced in veterans with PTSD. CONCLUSION Among US veterans of Iraq and Afghanistan, mental health diagnoses, especially PTSD, were associated with an increased risk of receiving opioids for pain, high-risk opioid use, and adverse clinical outcomes.

Substance use disorders in Iraq and Afghanistan veterans in VA healthcare, 2001–2010: Implications for screening, diagnosis and treatment.

BACKGROUND The prevalence and correlates of alcohol use disorder (AUD) and drug use disorder (DUD) diagnoses in Iraq and Afghanistan veterans who are new users of Department of Veterans Affairs (VA) healthcare nationwide has not been evaluated. METHODS VA administrative data were used in retrospective cross-sectional descriptive and multivariable analyses to determine the prevalence and independent correlates of AUD and DUD in 456,502 Iraq and Afghanistan veterans who were first-time users of VA healthcare between October 15, 2001 and September 30, 2009 and followed through January 1, 2010. RESULTS Over 11% received substance use disorder diagnoses: AUD, DUD or both; 10% received AUD diagnoses, 5% received DUD diagnoses and 3% received both. Male sex, age < 25 years, being never married or divorced, and proxies for greater combat exposure were independently associated with AUD and DUD diagnoses. Of those with AUD, DUD or both diagnoses, 55-75% also received PTSD or depression diagnoses. AUD, DUD or both diagnoses were 3-4.5 times more likely in veterans with PTSD and depression (p < 0.001). CONCLUSIONS Post-deployment AUD and DUD diagnoses were more prevalent in subgroups of Iraq and Afghanistan veterans and were highly comorbid with PTSD and depression. Stigma and lack of universal screening may have reduced the number of DUD diagnoses reported. There is a need for improved screening and diagnosis of substance use disorders and increased availability of integrated treatments that simultaneously address AUD and DUD in the context of PTSD and other deployment-related mental health disorders.

Childhood Trauma Associated with Short Leukocyte Telomere Length in Posttraumatic Stress Disorder

BACKGROUND Posttraumatic stress disorder (PTSD) is associated with increased risk for age-related diseases and early mortality. An accelerated rate of biological aging could contribute to this increased risk. To investigate, we assessed leukocyte telomere length (LTL), an emerging marker of biological age, in men and women with and without PTSD. We also examined childhood trauma, a risk factor for both PTSD and short LTL, as a potential contributor to short LTL in PTSD. METHODS Participants included 43 adults with chronic PTSD (n = 18 with multiple categories of childhood trauma) and 47 control subjects (none with multiple categories of childhood trauma) (mean age = 30.55, SD = 7.44). Exclusion criteria included physical illness, medication use, obesity, alcohol or substance abuse, and pregnancy. Structured clinical interviews were conducted to assess PTSD and other psychiatric disorders and childhood trauma exposure. LTL was measured with a quantitative polymerase chain reaction method. RESULTS As predicted, participants with PTSD had shorter age-adjusted LTL than control subjects. Exposure to childhood trauma was also associated with short LTL. In fact, childhood trauma seemed to account for the PTSD group difference in LTL; only participants with PTSD and exposure to multiple categories of childhood trauma had significantly shorter LTL than control subjects. CONCLUSIONS Childhood trauma is associated with short LTL in individuals with PTSD. Chronic exposure to the psychobiological sequelae of childhood trauma could increase risk for PTSD and short LTL. Thus, the lasting psychological impact of exposure to trauma in childhood might be accompanied by equally enduring changes at the molecular level.

Mental health diagnoses and utilization of VA non-mental health medical services among returning Iraq and Afghanistan veterans.

BACKGROUNDOver 35% of returned Iraq and Afghanistan veterans in VA care have received mental health diagnoses; the most prevalent is post-traumatic stress disorder (PTSD). Little is known about these patients’ use of non-mental health medical services and the impact of mental disorders on utilization.OBJECTIVETo compare utilization across three groups of Iraq and Afghanistan veterans: those without mental disorders, those with mental disorders other than PTSD, and those with PTSD.DESIGN AND PARTICIPANTSNational, descriptive study of 249,440 veterans newly utilizing VA healthcare between October 7, 2001 and March 31, 2007, followed until March 31, 2008.MEASUREMENTSWe used ICD9-CM diagnostic codes to classify mental health status. We compared utilization of outpatient non-mental health services, primary care, medical subspecialty, ancillary services, laboratory tests/diagnostic procedures, emergency services, and hospitalizations during veterans’ first year in VA care. Results were adjusted for demographics and military service and VA facility characteristics.MAIN RESULTSVeterans with mental disorders had 42–146% greater utilization than those without mental disorders, depending on the service category (all P < 0.001). Those with PTSD had the highest utilization in all categories: 71–170% greater utilization than those without mental disorders (all P < 0.001). In adjusted analyses, compared with veterans without mental disorders, those with mental disorders other than PTSD had 55% higher utilization of all non-mental health outpatient services; those with PTSD had 91% higher utilization. Female sex and lower rank were also independently associated with greater utilization.CONCLUSIONSVeterans with mental health diagnoses, particularly PTSD, utilize significantly more VA non-mental health medical services. As more veterans return home, we must ensure resources are allocated to meet their outpatient, inpatient, and emergency needs.

Scared to Death? Generalized Anxiety Disorder and Cardiovascular Events in Patients With Stable Coronary Heart Disease: The Heart and Soul Study

CONTEXT Anxiety is common in patients with coronary heart disease (CHD), but studies examining the effect of anxiety on cardiovascular prognosis and the role of potential mediators have yielded inconsistent results. OBJECTIVES To evaluate the effect of generalized anxiety disorder (GAD) on subsequent cardiovascular events and the extent to which this association is explained by cardiac disease severity and potential behavioral or biological mediators. DESIGN Prospective cohort study (Heart and Soul Study). SETTING Participants were recruited between September 11, 2000, and December 20, 2002, from 12 outpatient clinics in the San Francisco Bay Area and were followed up until March 18, 2009. PARTICIPANTS One thousand fifteen outpatients with stable CHD followed up for a mean (SD) of 5.6 (1.8) years. MAIN OUTCOME MEASURES We determined the presence of GAD using the Diagnostic Interview Schedule. Proportional hazards models were used to evaluate the association of GAD with subsequent cardiovascular events and the extent to which this association was explained by potential confounders and mediators. RESULTS A total of 371 cardiovascular events occurred during 5711 person-years of follow-up. The age-adjusted annual rate of cardiovascular events was 9.6% in the 106 participants with GAD and 6.6% in the 909 participants without GAD (P = .03). After adjustment for demographic characteristics, comorbid conditions (including major depressive disorder), cardiac disease severity, and medication use, GAD remained associated with a 62% higher rate of cardiovascular events (hazard ratio, 1.62; 95% confidence interval, 1.11-2.37; P = .01). Additional adjustment for a variety of potential behavioral and biological mediators had little effect on this association (hazard ratio, 1.74; 95% confidence interval, 1.13-2.67; P = .01). CONCLUSIONS In outpatients with CHD, a robust association between GAD and cardiovascular events was found that could not be explained by disease severity, health behaviors, or biological mediators. How GAD leads to poor cardiovascular outcomes deserves further study.

Depressive Symptoms, Health Behaviors, and Subsequent Inflammation in Patients With Coronary Heart Disease: Prospective Findings From the Heart and Soul Study

OBJECTIVE Depression has been associated with inflammation in patients with coronary heart disease. However, it is uncertain whether depressive symptoms lead to inflammation or vice versa. METHOD The authors evaluated 667 outpatients with established coronary heart disease from the Heart and Soul Study. Depressive symptoms were assessed annually with the 9-item Patient Health Questionnaire. Participants were categorized as having no significant depressive symptoms (score below 10 at all interviews), depressive symptoms (score of 10 or higher) at one interview, or depressive symptoms at two or more interviews. At baseline and 5-year follow-up, fasting blood samples were collected to measure three inflammatory biomarkers: fibrinogen, interleukin-6 (IL-6), and high-sensitivity C-reactive protein (hsCRP). RESULTS Of the 667 participants, 443 had no depressive symptoms, 86 had depressive symptoms at one assessment, and 138 had depressive symptoms at two or more annual assessments. Across the three groups, greater depressive symptoms were associated with higher subsequent log-transformed levels of IL-6 and hsCRP, and the association with higher fibrinogen levels approached significance. Baseline inflammation did not predict subsequent depressive symptoms. The association of depressive symptoms with subsequent inflammation levels was eliminated after adjustment for health behaviors associated with depression-physical inactivity, smoking, and higher body mass index. CONCLUSIONS Depressive symptoms predicted higher IL-6 and hsCRP levels among outpatients with coronary heart disease, but higher inflammation levels did not predict subsequent depressive symptoms. The association between depressive symptoms and inflammation was no longer significant after adjustment for health behaviors, which suggests these behaviors may mediate depressive effects.

Gender differences in military sexual trauma and mental health diagnoses among Iraq and Afghanistan veterans with posttraumatic stress disorder.

OBJECTIVE We examined correlates of posttraumatic stress disorder (PTSD), including military sexual trauma (MST), in Iraq and Afghanistan veterans. We also compared mental health comorbidities by gender among veterans with PTSD, with and without MST. METHODS Retrospective data analyses were conducted using Department of Veterans Affairs (VA) administrative data from 213,803 Iraq and Afghanistan veterans and the subset diagnosed with PTSD from April 1, 2002, to October 1, 2008. We used descriptive statistics and multivariate logistic regression compared by gender to investigate independent correlates and mental health comorbidities associated with PTSD, with and without MST. RESULTS Among women with PTSD, 31% screened positive for MST; 1% of men with PTSD screened positive for MST. Among those with PTSD, veterans with MST had more comorbid mental health diagnoses than those without MST. Women with PTSD and MST were more likely to receive comorbid depression, anxiety, and eating disorder diagnoses, and men were more likely to receive comorbid substance use disorder diagnoses. CONCLUSIONS MST is associated with an increased prevalence of mental health disorders comorbid with PTSD. Better understanding comorbidity patterns will allow for targeted evaluation and treatment of returning veterans with MST.

Post-Traumatic Stress Disorder is Associated With Poor Health Behaviors: Findings From the Heart and Soul Study

OBJECTIVE Posttraumatic stress disorder (PTSD) results in substantial disability, including increased risk of cardiovascular disease (CVD). Poor health behaviors are major risk factors for initial and recurrent CVD events. Therefore, this study investigated whether PTSD is associated with poor health behaviors in patients with CVD. METHOD Cross-sectional study of 1,022 men and women with CVD. PTSD was assessed with the Computerized Diagnostic Interview Schedule for DSM-IV. Physical activity, medication adherence and smoking history were determined by self-report questionnaires. Multivariate logistic and linear regression models were used to evaluate the association of PTSD with health behaviors. RESULTS Of the 1,022 participants, 95 (9%) had PTSD. PTSD was associated with significantly higher rates of physical inactivity in terms of overall exercise (OR 1.6, 95% CI [1.0-2.6]; p = .049), light exercise (OR 1.7, 95% CI [1.0-2.9]; p = .045), and self-rated level of exercise compared to others of their age and sex (OR 1.8, 95% CI [1.0-3.0]; p = .047). Participants with PTSD were more likely to report medication nonadherence, including forgetting medications (OR 1.8, 95% CI [1.0-3.3]; p = .04) or skipping medications (OR 1.7, 95% CI [1.1-2.9]; p = .03). Participants with PTSD also reported a greater smoking history (β 6.4 pack years, 95% CI [1.8-10.9]; p = .006), which remained significant after adjustment for depression and income. CONCLUSIONS Among patients with heart disease, those with PTSD were more likely to report physical inactivity, medication nonadherence and smoking. The majority of these associations were explained by adjustment for comorbid depression and lower income.

Association of Cardiovascular Risk Factors With Mental Health Diagnoses in Iraq and Afghanistan War Veterans Using VA Health Care

To the Editor: The photograph accompanying the book review by Dr Smitherman is captioned as showing Abraham Lincoln at Bull Run. However, I believe that the photograph does not show Lincoln. Not only does the man not look like Lincoln (head too big, neck too short, arms too short, stance atypical), but there is no record that Lincoln ever visited the Bull Run battlefield. Furthermore, the photograph does not appear in the standard catalog of Lincoln photographs. Even the source of the photograph questions whether the subject is Lincoln. Possibly the man is Brigadier General Montgomery Meigs, who is known to have visited the battlefield and who has been mistaken for Lincoln by photograph historians in the past.
