Multimorbidity among Veterans Diagnosed with PTSD in the Veterans Health Administration Nationally

Prevalence of multimorbidity in people with and without severe mental illness: a systematic review and meta-analysis

BACKGROUND

People with severe mental illness, such as schizophrenia-spectrum disorder and bipolar disorder, face poorer health outcomes from multiple chronic illnesses. Physical multimorbidity, the coexistence of two or more chronic physical conditions, and psychiatric multimorbidity, the coexistence of three or more psychiatric disorders, are both emerging concepts useful in conceptualising disease burden. However, the prevalence of physical and psychiatric multimorbidity in this cohort is unknown. This study aimed to estimate the absolute prevalence of both physical and psychiatric multimorbidity in people with severe mental illness, and also compare the odds of physical multimorbidity prevalence against people without severe mental illness.

METHODS

We searched CINAHL, EMBASE, PubMed, and PsycINFO from inception until Feb 15, 2024, for observational studies that measured multimorbidity prevalence. To be included, studies had to have an observational study design, be conducted in an adult population (mean age ≥18 years) diagnosed with either schizophrenia-spectrum disorder or bipolar disorder, and include a measurement of occurrence of either physical multimorbidity (≥2 physical health conditions) or psychiatric multimorbidity (≥3 psychiatric conditions total, including the severe mental illness). From control studies, a random-effects meta-analysis compared odds of physical multimorbidity between people with and without severe mental illness. Absolute prevalence of physical and psychiatric multimorbidity in people with severe mental illness was also calculated. Sensitivity and meta-regression analyses tested an array of demographic, diagnostic, and methodological variables.

FINDINGS

From 11 144 citations we included 82 observational studies featuring 1 623 773 individuals with severe mental illness (specifically schizophrenia-spectrum disorder or bipolar disorder), of which 21 studies featured 13 235 882 control individuals without severe mental illness (descriptive data for the entire pooled cohorts were not available for numbers of males and females, age, and ethnicity). This study did not feature involvement of people with lived experience. The odds ratio (OR) of physical multimorbidity between people with and without severe mental illness was 2·40 (95% CI 1·57-3·65, k=11, p=0·0009). This ratio was higher in younger severe mental illness populations (mean age ≤40 years, OR 3·99, 95% CI 1·43-11·10) compared with older populations (mean age >40 years, OR 1·55, 95% CI 0·96-2·51; subgroup differences p=0·0013). For absolute prevalence, 25% of those with severe mental illness have physical multimorbidity (95% CI 0·19-0·32, k=29) and 14% have psychiatric multimorbidity (95% CI 0·08-0·23, k=21).

INTERPRETATION

This is the first meta-analysis to estimate physical alongside psychiatric multimorbidity prevalence, showing that these are common in people with schizophrenia-spectrum disorder and bipolar disorder. The greater burden of physical multimorbidity in people with severe mental illness compared with those without is higher for younger cohorts, reflecting a need for earlier intervention. Our findings speak to the utility of multimorbidity for characterising the disease burden associated with severe mental illness, and the importance of facilitating integrated physical and mental health care.

Depression and Differential Oral Health Status Among U.S. Adults With and Without Prior Active Duty Service in the U.S. Military, National Health and Nutrition Examination Survey 2011-2018

INTRODUCTION

Veterans suffer from lower overall well-being than non-veterans because of their unique life course. This study aims to compare the impact of depression on oral health for veteran and non-veteran populations.

MATERIALS AND METHODS

Data from 11,693 adults (18+) participating in the National Health and Nutrition Examination Survey (2011-2018) were analyzed. The outcome variables were dichotomous (at/above mean) decayed, missing, and filled teeth due to caries (DMFT), as well as the components, namely, missing teeth, filled teeth (FT), and decayed teeth (DT). The primary predictor variable combined depression screening outcome and veteran status (veteran/depressed, veteran/not depressed, non-veteran/depressed, and non-veteran/not depressed). Covariates included socioeconomic factors, demographics, wellness factors, and oral health-related habits. Associations between outcome and predictor variables were assessed with a fully adjusted logistic regression analysis.

RESULTS

Veterans, regardless of depression status, had more DMFT, FT, missing teeth, and DT compared to non-veterans. After controlling for covariates, veterans suffering from depression had higher odds of DT (1.5, 95% CI, 1.0-2.4) compared to non-veterans without depression. In general, veterans who screened negative for depression had better oral health compared to all groups, with lower odds of DT (0.7, 95% CI, 0.6-0.9) and higher odds of FT (1.4, 95% CI, 1.1-1.7) compared to non-veterans with and without depression.

CONCLUSIONS

This study found that not only veterans have higher odds of overall caries experience, but also veterans suffering from depression have higher odds of active caries compared to non-depressed veterans. Most veterans lack Veterans Health Administration dental benefits and face challenges maintaining oral health on top of medical and mental health burdens. Our results add further urgency to increasing dental care access for this vulnerable population because of the exacerbation of unmet oral health care needs attributable to the additional mental health challenges veterans face.

Adjustment disorder in the Armed Forces: a systematic review

BACKGROUND

In the UK military, adjustment disorder (AjD) is reported as one of the most diagnosed mental disorders, alongside depression, in personnel presenting to mental health services. Despite this, little is understood about what may predict AjD, common treatment or outcomes for this population.

AIM

The systematic review aimed to summarise existing research for AjD in Armed Forces (AF) populations, including prevalence and risk factors, and to outline clinical and occupational outcomes.

METHOD

A literature search was conducted in December 2020 to identify research that investigated AjD within an AF population (serving or veteran) following the PRISMA guidelines.

RESULTS

Eighty-three studies were included in the review. The AjD prevalence estimates in AF populations with a mental disorder was considerably higher for serving AF personnel (34.9%) compared to veterans (12.8%). Childhood adversities were identified as a risk factor for AjD. AjD was found to increase the risk of suicidal ideation, with one study reporting a risk ratio of 4.70 (95% Confidence Interval: 3.50-6.20). Talking therapies were the most common treatment for AjD, however none reported on treatment effectiveness.

CONCLUSION

This review found that AjD was commonly reported across international AF. Despite heterogeneity in the results, the review identifies several literature gaps.

Factors influencing length of hospital stay among veterans admitted to an inpatient psychiatric unit

It is well established that Veterans are at increased risk for mental health problems and associated hospitalization. While hospitalization is appropriate for acute stabilization, prolonged stays can contribute to reduced quality of life, increased healthcare expenditures, and trauma exposure with associated trauma-related symptoms. To reduce inpatient psychiatric length of stay and to improve patient outcomes, it is imperative that risk factors for prolonged length of stay are elucidated. The purpose of this retrospective chart review was to examine demographic and clinical characteristics and their association with inpatient psychiatric length of stay in a sample of Veterans. Demographic information collected included age and race. Clinical characteristics collected included primary admitting psychiatric diagnosis, number of psychiatric emergencies during hospitalization, utilization of restraint or seclusion, observation status, 30-day readmission status, adherence to psychiatric follow-up appointments post-discharge, and presence of suicidality. A total of 820 Veterans were included in the analysis. Age, primary psychiatric diagnosis, occurrence of a psychiatric emergency, and observation status were significant predictors of length of stay (F = 24.39, p < .001). There were significant differences in the average length of stay between Veterans with substance use disorders and those with psychotic disorders (B = 0.576, p < .001). Likewise, Veterans with neurocognitive disorders also had longer lengths of stay than those without neurocognitive disorders, respectively (B = 0.014, p < .001). In summary, quality of mental health care can be improved by reducing length of stay, but additional understanding related to risk factors is first needed.

The Costs and Health Benefits of Expanded Access to MDMA-assisted Therapy for Chronic and Severe PTSD in the USA: A Modeling Study

Background and Objective

Intensive psychotherapy assisted with 3,4-methylenedioxymethamphetamine (MDMA-AT) was shown in Phase 3 clinical trials to substantially reduce post-traumatic stress disorder (PTSD) symptoms compared to psychotherapy with placebo. This study estimates potential costs, health benefits, and net savings of expanding access to MDMA-AT to eligible US patients with chronic and severe PTSD.

Methods

Using a decision-analytic model, we compared the costs, deaths averted, and quality-adjusted life years (QALYs) gained of three, 10-year MDMA-AT coverage targets (25%, 50%, and 75%) compared to providing standard of care to the same number of eligible patients with chronic and severe PTSD. We used a payer perspective and discounted costs (in US$) and QALYs to 2020. We conducted one-way, scenario, and probabilistic sensitivity analyses and calculated the net monetary value of MDMA-AT using a cost-effectiveness threshold of $100,000 per QALY gained.

Results

Expanding access to MDMA-AT to 25–75% of eligible patients is projected to avert 43,618–106,932 deaths and gain 3.3–8.2 million QALYs. All three treatment targets are dominant or cost-saving compared to standard of care. Our sensitivity analyses found that accounting for parameter uncertainty and changes in various assumptions did not alter the main finding—MDMA-AT is dominant compared to standard of care.

Conclusion

Expanding access to MDMA-AT to patients with chronic and severe PTSD will provide substantial health and financial benefits. The precise magnitude is uncertain and will depend on the number of eligible patients and other inputs.

Association of symptom severity, pain and other behavioral and medical comorbidities with diverse measures of functioning among adults with post-traumatic stress disorder

Post-traumatic stress disorder (PTSD) is an often disabling mental disorder whose management typically focuses on reducing PTSD symptoms. Chronic pain and other comorbidities that commonly accompany PTSD symptoms may also be independently associated with disability. Using data from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions, we examined the independent association of PTSD symptom severity, pain interference, non-PTSD psychiatric and substance use disorders (SUD), and medical illnesses with each of four domains of function: mental health-related quality of life and physical functioning assessed with the Mental Health Composite Score (MCS) and Physical Function Score (PFS) of the Short Form-12; perceived social support from the Interpersonal Support and Evaluation List-12 (ISEL-12); and self-reported past year employment. Among 1779 individuals representing 11 million U.S. adults who met the Diagnostic and Statistical Manual-5 (DSM-5) criteria for Past Year PTSD, the MCS (41.2; SD 12.5), PFS (44.8; SD 13.2) and ISEL-12 (33.6; SD 7.2) indicated substantial disability when compared to population norms, and only 63.6% were employed. Multiple regression showed the MCS had a modest negative association with PTSD symptoms, pain interference, psychiatric multimorbidity and medical comorbidity although not with SUD. PFS and employment had significant negative associations with pain interference and medical comorbidity. ISEL-12 had a weak negative association with PTSD symptoms and non-PTSD psychiatric comorbidity. Common comorbidities thus significantly influence disability associated with PTSD, often more strongly than PTSD symptoms. PTSD treatment may require integrative multimorbidity management beyond a focus on PTSD symptoms.

Increased vascular α1-adrenergic receptor sensitivity in older adults with posttraumatic stress disorder

Posttraumatic stress disorder (PTSD) is an independent risk factor for the development of hypertension and cardiovascular disease. Patients with PTSD have heightened blood pressure and sympathetic nervous system reactivity; however, it is unclear if patients with PTSD have exaggerated vasoconstriction in response to sympathetic nerve activation that could also contribute to increased blood pressure reactivity. Therefore, we hypothesized that patients with PTSD have increased sensitivity of vascular α₁-adrenergic receptors (α1ARs), the major mediators of vasoconstriction in response to release of norepinephrine at sympathetic nerve terminals. To assess vascular α1AR sensitivity, we measured the degree of venoconstriction in a dorsal hand vein in response to exponentially increasing doses of the selective α1AR agonist, phenylephrine (PE), in 9 patients with PTSD (age = 59 ± 2 yr) and 10 age-matched controls (age = 60 ± 1 yr). Individual dose-response curves were generated to determine the dose of PE that induces 50% of maximal venoconstriction (i.e., PE ED₅₀) reflective of vascular α1AR sensitivity. In support of our hypothesis, PE ED₅₀ values were lower in PTSD compared with controls (245 ± 54 ng/min vs. 1,995 ± 459 ng/min, P = 0.012), indicating increased vascular α₁AR sensitivity in PTSD. The PTSD group also had an increase in slope of rise in venoconstriction, indicative of an altered venoconstrictive reactivity to PE compared with controls (19.8% ± 1.2% vs. 15.1% ± 1.2%, P = 0.009). Heightened vascular α₁AR sensitivity in PTSD may contribute to augmented vasoconstriction and blood pressure reactivity to sympathoexcitation and to increased cardiovascular disease risk in this patient population.

Gender Difference in Substance Use and Psychiatric Outcomes Among Dually Diagnosed Veterans Treated in Specialized Intensive PTSD Programs

OBJECTIVES

Posttraumatic stress disorder (PTSD) is a problem of growing importance among female veterans, which is especially challenging when accompanied by comorbid substance use disorder (SUD). Since women are still a small minority of Veterans Health Administration (VHA) patients, there is concern that outcomes among dually diagnosed women may be worse than among men.

METHOD

National program evaluation data were collected at admission and 4 months after discharge from 7,074 dually diagnosed veterans including 203 women (2.9%) treated at 57 specialized intensive VHA PTSD treatment programs between 1993 and 2011. Multiple regression was used to compare clinical change in women and men adjusting for baseline differences.

RESULTS

Women showed no significant differences from men in measures of substance use or total PTSD symptoms at admission although they were more likely to have experienced sexual trauma and less likely to report combat exposure. With adjustment for these differences, there were no significant gender differences in length of stay, satisfaction with treatment, or measures of change in substance use or total PTSD symptoms 4 months after discharge. Reductions in an index of days of substance use was associated with reduction in total PTSD symptoms among both women (R = 0.33; p = .01) and men (R = 0.44, p < .0001) with no significant gender difference.

CONCLUSION

No significant gender differences were observed in substance use or PTSD outcomes, despite the extreme minority status of women in VHA programs. Highly vulnerable women can benefit as much as men, even when treatment is not formally tailored to address gender-specific needs.

Posttraumatic Stress Disorder, Suicidal Ideation, and Suicidal Self-Directed Violence Among U.S. Military Personnel and Veterans: A Systematic Review of the Literature From 2010 to 2018

Rates of suicide and posttraumatic stress disorder remain high among United States military personnel and veterans. Building upon prior work, we conducted a systematic review of research published from 2010 to 2018 regarding: (1) the prevalence of suicidal ideation, suicide attempt, and suicide among United States military personnel and veterans diagnosed with posttraumatic stress disorder; (2) whether posttraumatic stress disorder was associated with suicidal ideation, suicide attempt, and suicide among United States military personnel and veterans. 2,106 titles and abstracts were screened, with 48 articles included. Overall risk of bias was generally high for studies on suicidal ideation or suicide attempt and low for studies on suicide. Across studies, rates of suicidal ideation, suicide attempt, and suicide widely varied based on study methodology and assessment approaches. Findings regarding the association between posttraumatic stress disorder diagnosis with suicidal ideation and suicide were generally mixed, and some studies reported that posttraumatic stress disorder was associated with lower risk for suicide. In contrast, most studies reported significant associations between posttraumatic stress disorder and suicide attempt. These findings suggest complex associations between posttraumatic stress disorder and suicidal ideation, suicide attempt, and suicide, which are likely influenced by other factors (e.g., psychiatric comorbidity). In addition, most samples were comprised of veterans, rather than military personnel. Further research is warranted to elucidate associations between posttraumatic stress disorder and suicidal ideation, suicide attempt, and suicide, including identification of moderators and mediators of this relationship. Addressing this among United States military personnel, by gender, and in relation to different trauma types is also necessary.

Patterns of comorbidity associated with ICD-11 PTSD among older adults in the United States

Little research has been conducted on posttraumatic stress disorder (PTSD) comorbidity among older adults regarding the description of PTSD in the 11^th version of the International Classification of Diseases (ICD-11). This study sought to provide evidence of a dimensional model of psychopathology using the 'Hierarchical Taxonomy of Psychopathology' (HiTOP) model as a theoretical framework to explain patterns of ICD-11 PTSD comorbidity. Distinct patterns of ICD-11 PTSD comorbidity among a nationally representative sample (n = 530) of adults aged 60 years and older from the United States were examined using latent class analysis (LCA). Covariates associated with comorbidity classes were assessed through multinomial logistic regression. ICD-11 PTSD was highly comorbid with other psychopathologies. LCA results favoured a two-class solution. Class 1 (71.7%) was characterised by moderate probabilities for major depressive disorder and alcohol use disorder; Class 2 (28.3%) was characterised by a moderate-high probability of general psychopathology and was associated with lower social support, spousal/partner physical abuse, and history of attempted suicide. PTSD was highly comorbid with other disorders among older adults. Distinct patterns of PTSD comorbidity exist among this cohort and these findings can aid clinicians and researchers in understanding and predicting maladaptive responses to trauma and associated psychopathology.

Factors associated with PTSD symptom improvement among Iraq and Afghanistan veterans receiving evidenced-based psychotherapy

BACKGROUND

Despite availability of evidence-based psychotherapies (EBPs) for posttraumatic stress disorder (PTSD), not all veterans who initiate EBPs experience benefit. Better understanding factors associated with clinically significant improvement can help ameliorate care.

METHODS

A cohort of Iraq and Afghanistan War veterans who initiated an EBP was identified (N = 32,780) with ≥1 post-deployment psychotherapy visit at the Veterans Health Administration from 10/2001-6/2017, a post-deployment PTSD diagnosis, and ≥2 PTSD symptom measures. We used random-effects logistic regression to assess whether patient-level, diagnostic, and treatment factors were associated with achieving symptom improvement.

RESULTS

Increased odds of PTSD symptom improvement were seen in women (OR = 1.19; 95% CI: 1.09--1.29), those who initiated EBP within a year of engaging in mental healthcare compared with the delayed EBP group (OR = 1.20; 95% CI: 1.14--1.28), those who completed at least 8 EBP sessions in 16 weeks (OR = 1.23; 95% CI:1.11--1.36), those who received PE only (vs. CPT or both; OR = 2.23; 95% CI: 1.86--2.68) or CPT individual therapy only (vs. CPT group or both; OR = 1.34; 95% CI: 1.22--1.48), and those with a drug dependence diagnosis (OR = 1.24; 95% CI: 1.11--1.39). Decreased odds of improvement were seen in Black veterans (OR=0.75; 95% CI: 0.69--0.81) and those with service-connected disability (OR = 0.61; 95% CI: 0.52--0.71).

LIMITATIONS

Diagnoses were from medical charts and not confirmed with gold standard assessment tools; we only included veterans with at least two PTSD measurements, which may cause bias.

CONCLUSION

Modifiable factors associated with PTSD improvement (timing, dose, and modality) can be used to improve EBP outcomes.

Comparing the effectiveness of VA residential PTSD treatment for veterans who do and do not report a history of MST: A national investigation

The Department of Veterans Affairs (VA) has implemented initiatives to promote veterans' recovery from the health sequelae of military sexual trauma (MST), including posttraumatic stress disorder (PTSD). MST can impact emotion regulation, interpersonal functioning, and perceptions of trust and safety, as well as increase risk for psychiatric comorbidity, which may impede PTSD treatment.. VA PTSD Residential Rehabilitation Treatment Programs (RRTPs) may facilitate the therapeutic process by offering increased structure, support, and adjunctive services. Limited research has examined the effect of MST on PTSD RRTP outcomes. Utilizing data from 7918 men and women veterans participating in a VA PTSD RRTP, the impact of the experience of MST on rates of program completion and changes in PTSD symptoms during and after treatment were examined. Rates of program completion were similar between those who did and did not report experiencing MST. Multilevel modeling was utilized to examine the impact of MST on PTSD symptoms after accounting for gender, age, race/ethnicity, and program completion. MST survivors endorsed more severe PTSD symptoms at admission; however, PTSD symptom severity scores were similar to those who did not report experiencing MST by discharge. Additionally, MST survivors had larger initial reductions in PTSD symptoms, followed by a greater recurrence of PTSD symptoms over time, compared to those who did not report experiencing MST. MST survivors appear able to participate in and benefit from PTSD RRTPs. Nonetheless, the increased recurrence of PTSD symptoms following discharge from residential treatment indicates the need for strategies to maintain post-treatment gains among MST survivors.
