Co-occurring medical and mental illness and substance use disorders among veteran clinic users with spinal cord injury patients with complexities

Cognitive, behavioral and psychiatric symptoms in patients with spinal cord injury: a scoping review

Spinal Cord Injury (SCI) is a condition where the spinal cord is damaged and experiences partial or complete loss of motor and/or sensory function, which is typically less than normal. After SCI, patients may exhibit more severe psychiatric symptoms and experience cognitive impairments, including reduced speed and attention processing capacity, as well as difficulties with executive function and episodic memory retention. Among the behavioral and psychiatric symptoms, depression, anxiety, substance use disorder, and posttraumatic stress disorder are the most common. This review aims to investigate the cognitive, behavioral, or psychiatric symptoms of the patient with SCI and their influence on the rehabilitation process. Studies were identified from an online search of PubMed, Web of Science, Cochrane Library, and Embase databases. Studies published between 2013-2023 were selected. This review has been registered on OSF (n) 3KB2U. We have found that patients with SCI are at high risk of cognitive impairment and experience a wide range of difficulties, including tasks based on processing speed and executive function. This clinical population may experience adjustment disorders with depression and anxiety, as well as other psychiatric symptoms such as fatigue, stress, and suicidal ideation. This review has demonstrated that SCI patients may experience psychiatric symptoms and cognitive impairments that affect their functioning. At the same time, these patients may be more prone to various adjustment and mood disorders. Moreover, these two aspects may interact with each other, causing a range of symptoms, increasing the risk of hospitalization, and delaying the rehabilitation process.

Evaluation of clinical outcomes and employment status in veterans with dual diagnosis of traumatic brain injury and spinal cord injury

PURPOSE

To examine clinical outcomes and employment status in Veterans with and without a dual diagnosis of traumatic brain injury (TBI) and spinal cord injury (SCI).

METHODS

This cross-sectional study examined a national sample of Veterans enrolled in the VA Million Veteran Program who completed the Comprehensive TBI Evaluation (CTBIE) as part of the Veterans Health Administration's TBI Screening and Evaluation Program. Veterans (N = 12,985) were classified into the following TBI/SCI groups using CTBIE data: those with a dual diagnosis of TBI and SCI (TBI+/SCI+); those with a history of TBI but no SCI (TBI+/SCI-); and those with no history of TBI or SCI (TBI-/SCI-; i.e., the control group). CTBIE-derived outcomes included neurobehavioral symptoms, comorbid psychiatric symptoms, pain and pain interference, and employment status.

RESULTS

Chi-square analyses showed significant associations between TBI/SCI group and all clinical outcomes evaluated (all p's < .001; V = 0.07-0.11). In general, the TBI+/SCI+ and TBI +/SCI- groups endorsed comparable levels of neurobehavioral symptoms, psychiatric symptoms, and pain, but significantly greater rates of symptoms and pain relative to the TBI-/SCI- group. Effect sizes for all pairwise comparisons were small (φ = 0.01-0.11). Finally, there was no significant association between TBI/SCI group and employment status (p = .170; V = 0.02), with all three groups showing relatively comparable rates of unemployment.

CONCLUSIONS

Regardless of SCI status, Veterans with TBI history endorsed poorer clinical outcomes than Veterans without TBI and SCI. However, rates of unemployment were similarly high across all three groups. Findings suggest that any Veteran completing the CTBIE may be at risk for poor clinical and employment outcomes.

Dual utilization of Medicare and VA outpatient care among Veterans with spinal cord injuries and disorders

OBJECTIVE

Veterans with spinal cord injuries and disorders (SCI/D) utilizing Veterans Affairs healthcare facilities are also Medicare eligible. Use of multiple health care systems potentially duplicates or fragments care in this population; yet little is known about those using multiple systems. This study describes dual use of services paid for by VA and Medicare among Veterans with SCI/D.

DESIGN

Retrospective, cross-sectional, observational study.

PARTICIPANTS

Veterans with SCI/D (n = 13,902) who received healthcare services within the VA SCI System of Care and were eligible for or enrolled in Medicare in 2011.

INTERVENTIONS

N/A.

OUTCOME MEASURES

Patient characteristics, average number of visits and patient level frequencies of reasons for visits were determined for individuals within healthcare utilization (VA only, Medicare only, or dual VA/Medicare) groups. Multinomial logistic regression analyses were used to investigate associations of patient variables on dual use.

RESULTS

65.3% of Veterans with SCI/D were VA only users for outpatient encounters, 4.4% had encounters paid for by Medicare only, and 30.3% were dual users. Veterans were less likely to be VA only users if they were older than 69 and if they had been injured for greater than ten years. African American Veterans with SCI (compared to white) were more likely to be VA only users.

CONCLUSION

A substantial number (∼30%) of Veterans with SCI/D are dual users. These numbers highlight the importance of improved strategies to coordinate care and increase health information sharing across systems.

Association Between Anxiety Symptoms, Depression Symptoms, and Life Satisfaction Among Individuals 1 Year After Spinal Cord Injury: Findings From the SCIRehab Project

Objective

To examine the association between anxiety symptoms, depression symptoms, and life satisfaction 1 year after SCI.

Design

Cross-sectional analysis of data from the SCIRehab Project. A linear regression model estimated the association between anxiety symptoms and life satisfaction and tested the moderating effect of depression symptoms on the association between anxiety symptoms and depression symptoms with an interaction term.

Setting

Six rehabilitation facilities across the United States.

Participants

A total to 940 persons older than 12 years who received inpatient spinal cord injury (SCI) rehabilitation between 2007 and 2009 were followed up 1 year post injury (n=940).

Interventions

None

Main Outcome Measures

Life satisfaction 1 year after SCI measured via the Satisfaction With Life Scale.

Results

Unadjusted analyses showed anxiety symptoms were associated with decreased life satisfaction for individuals with SCI. In adjusted analyses, anxiety symptoms were not associated with life satisfaction. In adding an interaction term, anxiety symptoms were associated with 2 points lower life satisfaction holding the other variables constant (P=.02). There was a moderating effect of depression symptoms on the association between anxiety symptoms and life satisfaction. Persons with anxiety symptoms had lower life satisfaction scores at lower levels of depression symptoms but higher life satisfaction scores at higher levels of depression symptoms than persons with no anxiety.

Conclusions

In clinical settings, both anxiety and depression symptoms should be monitored, measured, and treated together to optimally improve life satisfaction for persons with SCI. Prioritizing interventions known to have transdiagnostic effects may achieve the best results.

Demographic and Health Profiles of People Living With Traumatic Spinal Cord Injury in the United States During 2015-2019: Findings from the Spinal Cord Injury Model Systems Database

OBJECTIVE

To estimate the population profile of people living with traumatic spinal cord injury (TSCI) to help evaluate health care needs of this aging population.

DESIGN

Cross-sectional study.

SETTING

SCI Model Systems (SCIMS) centers in the United States.

PARTICIPANTS

Individuals (N=20,437) who: (1) incurred a TSCI between 1972 and 2019, (2) were initially treated at one of the SCIMS centers, and (3) were alive during the period from 2015 to 2019.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Demographics, injury characteristics, health conditions, and social participation, as compared with previous estimates in 2008 and general population statistics in 2017.

RESULTS

People living with TSCI during the period from 2015-2019 (mean years since injury, 18y; 79.4% male, and 62.5% White) were older (51.6 vs 45.0y) and had a higher percentage of C1-C4 (21.9% vs 17.0%) and American Spinal Injury Association Impairment Scale D injuries (31.5% vs 26.0%) compared with the 2008 TSCI population profile. Although the proportion of people with a bachelor's degree or higher was similar between the TSCI and general US populations (30.7% vs 32.0%), the employment rate was lower in the TSCI population (24.0% vs 59.5%). People are affected by various medical problems over time post TSCI. The prevalence of pain and urinary tract infection remained high over postinjury years, at 86.1% and 52.6%, respectively. Rehospitalization and depression were most common during the first year (34.9% and 22.3%, respectively), and pressure injury was more common among those 20 years or more postinjury (>30.0%). Health conditions declined with advanced age, including self-perceived health, diabetes, and institutional residence. People who survived TSCI for years, however, had relatively good degrees of independence and social participation.

CONCLUSION

Study findings highlight the need for greater involvement of primary care providers and geriatricians in the continuity of care for SCI to promote healthy aging. Improvement in employment should also be the target in promoting social participation and quality of life.

Using Inferred Mobility Status to Estimate the Time to Major Depressive Disorder Diagnosis Post-Spinal Cord Injury

OBJECTIVE

Estimate (1) prevalence of major depressive disorder (MDD) diagnosis; (2) risk factors associated with MDD diagnosis; (3) time at which MDD is diagnosed post-spinal cord injury (SCI); and (4) interaction of inferred mobility status (IMS) in a commercially insured population over 3 years.

DESIGN

Retrospective longitudinal cohort design.

SETTING

A commercial insurance claims database from January 1, 2010 to December 31, 2013.

PARTICIPANTS

Individuals with an index cervical or thoracic SCI in 2011 or 2012, without history of MDD ≤30 days pre-SCI (N=1409).

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

Prevalence of, risk factors associated with, and time to MDD diagnosis post-SCI. A stratified survival analysis using IMS, based upon durable medical equipment (DME) claims, was also completed.

RESULTS

Post-SCI, 294 out of 1409 (20.87%) were diagnosed with new-onset MDD. Significant (P<.05) risk factors included: employment, length of index hospitalization, discharge from index hospitalization with healthcare services, rehabilitation services post-SCI, and 2 of 5 IMS comparisons. Median time to MDD was 86 days. Survival analysis demonstrated a significant difference between 6 of 10 IMS comparisons. Regarding new-onset or recurring MDD, 432 out of 1409 (30.66%) were diagnosed post-SCI. Significant risk factors included: female, employment, length of index hospitalization, discharge from index hospitalization with healthcare services, rehabilitation services post-SCI, MDD>30 days pre-SCI, catheter claims, and 2 of 5 IMS comparisons. Median time to MDD was 74 days. Survival analysis demonstrated a significant difference between 4 of 10 IMS comparisons.

CONCLUSIONS

Prevalence of MDD post-SCI is greater than the general population. Stratification by IMS illustrated that individuals with greater inferred reliance on DME are at a greater risk for MDD and have shorter time to MDD diagnosis post-SCI.

Prevention and management of osteoporosis and osteoporotic fractures in persons with a spinal cord injury or disorder: A systematic scoping review

Objectives: The primary objective was to review the literature regarding methodologies to assess fracture risk, to prevent and treat osteoporosis and to manage osteoporotic fractures in SCI/D.Study Design: Scoping review.Settings/Participants: Human adult subjects with a SCI/D.Outcome measures: Strategies to identify persons with SCI/D at risk for osteoporotic fractures, nonpharmacological and pharmacological therapies for osteoporosis and management of appendicular fractures.Results: 226 articles were included in the scoping review. Risk of osteoporotic fractures in SCI is predicted by a combination of DXA-defined low BMD plus clinical and demographic characteristics. Screening for secondary causes of osteoporosis, in particular hyperparathyroidism, hyperthyroidism, vitamin D insufficiency and hypogonadism, should be considered. Current antiresorptive therapies for treatment of osteoporosis have limited efficacy. Use of surgery to treat fractures has increased and outcomes are good and comparable to conservative treatment in most cases. A common adverse event following fracture was delayed healing.Conclusions: Most of the research in this area is limited by small sample sizes, weak study designs, and significant variation in populations studied. Future research needs to address cohort definition and study design issues.

Mental disorder prevalence among U.S. Department of Veterans Affairs outpatients with spinal cord injuries

OBJECTIVES

Depression and other mental disorders are more prevalent among individuals living with spinal cord injury (SCI) than in the community at large, and have a strong association with quality of life. Yet little is known about the prevalence and predictors of mental disorders among U.S. military Veterans living with SCI. The primary aim of this study was to present an estimate of mental disorder point prevalence in this population. The secondary aim was to examine the relationship of mental disorders to demographics, injury characteristics, and other clinically relevant features such as impairment from mental health problems and life satisfaction.

DESIGN

Cross-sectional.

SETTING

A SCI & Disorders Center at a U.S. Veterans Affairs Medical Center.

PARTICIPANTS/METHODS

Administrative and medical records of 280 Veterans who attended annual comprehensive SCI evaluations were evaluated. Demographics, injury characteristics, self-reported mental and emotional functioning (i.e. SF-8 Health Survey), and clinician-determined mental disorder diagnoses were attained.

RESULTS

Overall, 40% of patients received at least one mental disorder diagnosis, most commonly depressive disorders (19%), posttraumatic stress disorder (12%), and substance or alcohol use disorders (11%). Several patient characteristics predicted mental disorders, including age, racial minority identity, non-traumatic SCI etiology, and incomplete (i.e. AIS D) vs. complete injury. Mental disorders were associated with greater impairment from health and mental health-related problems and less satisfaction with life.

CONCLUSIONS

Mental disorders are common among outpatients receiving VA specialty care for SCI. These findings highlight the importance of having adequate and effective available mental health services available for Veterans with SCI.

Effect of Family Caregiving on Depression in the First 3 Months After Spinal Cord Injury

Objective

To investigate the effect of family caregiving on depression in the first 3 months after spinal cord injury (SCI).

Methods

A retrospective study was carried out on 76 patients diagnosed with an SCI from January 2013 to December 2016 at the Department of Physical Medicine and Rehabilitation of Kyungpook National University Hospital, Korea. Clinical characteristics including age, gender, level of injury, completeness of the injury, time since injury, caregiver information, etiology, and functional data were collected through a retrospective review of medical records. Depression was assessed using the Beck Depression Inventory (BDI). Patients with 14 or more points were classified as depressed and those with scores of 13 or less as non-depressed group.

Results

Of the 76 patients, 33 were in the depressed group with an average BDI of 21.27±6.17 and 43 patients included in the non-depressed group with an average BDI of 4.56±4.20. The BDI score of patients cared by unlicensed assistive personnel (UAP) was significantly higher than that of patients cared by their families (p=0.020). Univariate regression analysis showed that motor complete injury (p=0.027), UAP caregiving (p=0.022), and Ambulatory Motor Index (p=0.019) were associated with depression after SCI. Multivariate binary logistic regression analysis showed that motor completeness (p=0.002) and UAP caregiving (p=0.002) were independent risk factors.

Conclusion

Compared with UAP, family caregivers lowered the prevalence of depression in the first 3 months after SCI.

Increased psychological distress among individuals with spinal cord injury is associated with central neuropathic pain rather than the injury characteristics

STUDY DESIGN

Cross-sectional study.

OBJECTIVES

Central neuropathic pain (CNP) is common after spinal cord injury (SCI). The psychological impact of CNP is not clear. Previous studies reported depression and pain catastrophizing among patients with SCI and CNP; however, the lack of control groups prevented discerning whether these were attributed to CNP or to the SCI itself. The aim was to examine the psychological distress among individuals with SCI with and without CNP and controls to evaluate its impact and possible source.

SETTING

Outpatient clinic of a large rehabilitation center.

METHODS

Individuals with SCI and CNP (n = 27) and without CNP (n = 23), and able-bodied controls (n = 20) participated. Data collection included sociodemographics, SCI characteristics, and level of post-traumatic stress disorder (PTSD), anxiety, stress, depression, and pain catastrophizing. The sensory, affective, and cognitive dimensions of CNP were analyzed.

RESULTS

Individuals with SCI and CNP exhibited elevated levels of PTSD, anxiety, stress, depression, and pain catastrophizing compared to the two control groups, which presented similar levels. The psychological variables among the CNP group correlated positively only with the affective dimension of CNP. Neither CNP nor the psychological variables correlated with SCI characteristics.

CONCLUSIONS

Irrespective of CNP intensity, the affective dimension (suffering) is associated with increased psychological distress. Perhaps individual differences in the response to SCI and/or individual traits rather than the mere exposure to SCI may have a role in the emergence of CNP and psychological distress/mood dysfunction. Rehabilitation programs should prioritize stress management and prevention among individuals with SCI and CNP.

Examining the relationship between post-traumatic stress disorder and social participation among Veterans with spinal cord injuries and disorders

PURPOSE

The objectives of this study were to examine differences in social participation among Veterans with spinal cord injuries/disorders with and without post-traumatic stress disorder, and determine if lower social participation was independently associated with having post-traumatic stress disorder.

METHODS

A cross-sectional mailed national survey was sent to a national sample of Veterans with spinal cord injuries/disorders who received prior-year Veterans Affairs healthcare. Surveys provided data on: demographics, health conditions, injury characteristics, and social participation. Analyses included bivariate comparisons, and multivariate logistic regression to determine if lower social participation was independently associated with post-traumatic stress disorder.

RESULTS

Veterans with (vs. without) post-traumatic stress disorder (n = 896) reported lower social participation (40.2 vs. 43.9, p < 0.0001). Multivariate analyses showed that longer duration of injury (OR = 0.98, 95% CI: 0.97-1.00, p = 0.04) and white race (OR = 0.62, 95% CI: 0.38-1.01, p = 0.05) were associated with lower odds of post-traumatic stress disorder, while a greater number of health conditions (OR = 1.43, 95% CI: 1.25-1.64, p < 0.0001) was associated with greater odds. When controlling for covariates, lower social participation was independently associated with post-traumatic stress disorder (OR = 0.94, 95% CI: 0.90-0.98, p = 0.003).

CONCLUSIONS

Results indicate post-traumatic stress disorder is associated with lower social participation in Veterans with spinal cord injuries/disorders, independent of other factors that may impact participation. Efforts to screen for and treat post-traumatic stress disorder among persons with spinal cord injuries/disorders, regardless of injury-specific factors, are needed to improve participation. Implications for Rehabilitation Individuals with spinal cord injuries/disorders often have post-traumatic stress disorder; in Veterans with spinal cord injuries/disorders this may be compounded by trauma incurred through military experiences. Social participation, an important aspect of rehabilitation and community integration following spinal cord injury or disorder, may be hindered by symptoms of post-traumatic stress disorder. Our data show that post-traumatic stress disorder is associated with lower social participation in Veterans with spinal cord injuries/disorders, independent of other factors that may impact participation. These results indicate that efforts to screen for and treat post-traumatic stress disorder among persons with spinal cord injuries/disorders, regardless of injury-specific factors, are needed to improve participation in this patient population.

Dual-energy X-ray absorptiometry and fracture prediction in patients with spinal cord injuries and disorders

Low T-scores at the hip predict incident fractures in persons with a SCI.

INTRODUCTION

Persons with a spinal cord injury (SCI) have substantial morbidity and mortality following osteoporotic fractures. The objective of this study was to determine whether dual-energy X-ray absorptiometry (DXA) measurements predict osteoporotic fractures in this population.

METHODS

A retrospective historical analysis that includes patients (n = 552) with a SCI of at least 2 years duration who had a DXA performed and were in the VA Spinal Cord Disorders Registry from fiscal year (FY) 2002-2012 was performed.

RESULTS

The majority of persons (n = 455, 82%) had a diagnosis of osteoporosis or osteopenia, with almost half having osteoporosis. BMD and T-scores at the lumbar spine were not significantly associated with osteoporotic fractures (p > 0.48) for both. In multivariable analyses, osteopenia (OR = 4.75 95% CI 1.23-17.64) or osteoporosis (OR = 4.31, 95% CI 1.15-16.23) compared with normal BMD was significantly associated with fractures and higher T-scores at the hip were inversely associated with fractures (OR 0.73 (95% CI 0.57-0.92)). There was no significant association of T-scores or World Health Organization (WHO) classification with incident fractures in those with complete SCI (p > 0.15 for both).

CONCLUSION

The majority (over 80%) of individuals with a SCI have osteopenia or osteoporosis. DXA-derived measurements at the hip, but not the lumbar spine, predict fracture risk in persons with a SCI. WHO-derived bone density categories may be useful in classifying fracture risk in persons with a SCI.

Documentation of preventive care for pressure ulcers initiated during annual evaluations in SCI

OBJECTIVE

Community-acquired pressure ulcers (PrUs) are a frequent cause of hospitalization of Veterans with spinal cord injury (SCI). The Veterans Health Administration (VHA) recommends that SCI annual evaluations include assessment of PrU risk factors, a thorough skin inspection and sharing of recommendations for PrU prevention strategies. We characterized consistency of preventive skin care during annual evaluations for Veterans with SCI as a first step in identifying strategies to more actively promote PrU prevention care in other healthcare encounters.

DESIGN/SETTING/PARTICIPANTS

Retrospective cross-sectional observational design, including review of electronic medical records for 206 Veterans with SCI admitted to 2 VA SCI centers from January-December, 2011.

OUTCOME MEASURES

Proportion of applicable skin health elements documented (number of applicable elements/skin health elements documented).

RESULTS

Our sample was primarily white (78%) male (96.1%), and mean age = 61 years. 40% of participants' were hospitalized for PrU treatment, with a mean of 294 days (median = 345 days) from annual evaluation to the index admission. On average, Veterans received an average of 75.5% (IQR 68-86%) of applicable skin health elements. Documentation of applicable skin health elements was significantly higher during inpatient vs. outpatient annual evaluations (mean elements received = 80.3% and 64.3%, respectively, P > 0.001). No significant differences were observed in documentation of skin health elements by Veterans at high vs. low PrU risk.

CONCLUSION

Additional PrU preventive care in the VHA outpatient setting may increase identification and detection of PrU risk factors and early PrU damage for Veterans with SCI in the community, allowing for earlier intervention.

The epidemiology of substance use disorders in US Veterans: A systematic review and analysis of assessment methods

BACKGROUND

Substance use disorders (SUDs), which encompass alcohol and drug use disorders (AUDs, DUDs), constitute a major public health challenge among US veterans. SUDs are among the most common and costly of all health conditions among veterans.

OBJECTIVES

This study sought to examine the epidemiology of SUDs among US veterans, compare the prevalence of SUDs in studies using diagnostic and administrative criteria assessment methods, and summarize trends in the prevalence of SUDs reported in studies sampling US veterans over time.

METHODS

Comprehensive electronic database searches were conducted. A total of 3,490 studies were identified. We analyzed studies sampling US veterans and reporting prevalence, distribution, and examining AUDs and DUDs.

RESULTS

Of the studies identified, 72 met inclusion criteria. The studies were published between 1995 and 2013. Studies using diagnostic criteria reported higher prevalence of AUDs (32% vs. 10%) and DUDs (20% vs. 5%) than administrative criteria, respectively. Regardless of assessment method, both the lifetime and past year prevalence of AUDs in studies sampling US veterans has declined gradually over time.

CONCLUSION

The prevalence of SUDs reported in studies sampling US veterans are affected by assessment method. Given the significant public health problems of SUDs among US veterans, improved guidelines for clinical screening using validated diagnostic criteria to assess AUDs and DUDs in US veteran populations are needed.

SCIENTIFIC SIGNIFICANCE

These findings may inform VA and other healthcare systems in prevention, diagnosis, and intervention for SUDs among US veterans.

Depression Trajectories During the First Year After Spinal Cord Injury

OBJECTIVE

To determine the number and type of longitudinal depression trajectories during the first year after spinal cord injury (SCI) and to identify baseline predictors of these trajectories.

DESIGN

Cohort study.

SETTING

Rehabilitation and postacute community settings.

PARTICIPANTS

Of 168 consecutive admissions to inpatient rehabilitation for acute SCI, 141 (115 men, 26 women) patients were enrolled in a randomized controlled trial telephone follow-up intervention, which showed no outcome differences, and completed assessments on at least 2 of the 4 follow-up occasions (3, 6, 9, and 12 months after SCI). Participants were on average 41 years old, most were non-Hispanic (96%) and white (86%), and 61.7% had tetraplegia.

INTERVENTIONS

Data were drawn from the ineffective randomized controlled trial.

MAIN OUTCOME MEASURE

Patient Health Questionnaire-9 (PHQ-9).

RESULTS

Unconditional linear latent class growth analysis models of PHQ-9 total scores revealed an optimal 3-class solution: stable low depression (63.8%), mild to moderate depression (29.1%), and persistent moderate to severe depression (7.1%). Preinjury mental health history and baseline pain, quality of life, and grief predicted class membership.

CONCLUSIONS

The modal response to SCI was stable low depression, whereas persistent moderate to severe depression primarily represented a continuation or relapse of preinjury depression. This line of research has the potential to improve identification of subgroups destined for poor outcomes and to inform early intervention studies.

Sex differences in mental health and substance use disorders and treatment entry among justice-involved Veterans in the Veterans Health Administration

BACKGROUND

Over half of veterans in the criminal justice system have mental health or substance use disorders. However, there is a critical lack of information about female veterans in the criminal justice system and how diagnosis prevalence and treatment entry differ by sex.

OBJECTIVES

To document prevalence of mental health and substance use disorder diagnoses and treatment entry rates among female veterans compared with male veterans in the justice system.

RESEARCH DESIGN

Retrospective cohort study using national Veterans Health Administration clinical/administrative data from veterans seen by Veterans Justice Outreach Specialists in fiscal years 2010-2012.

SUBJECTS

A total of 1535 females and 30,478 male veterans were included.

MEASURES

Demographic characteristics (eg, sex, age, residence, homeless status), mental health disorders (eg, depression, post-traumatic stress disorder), substance use disorders (eg, alcohol and opioid use disorders), and treatment entry (eg, outpatient, residential, pharmacotherapy).

RESULTS

Among female veterans, prevalence of mental health and substance use disorders was 88% and 58%, respectively, compared with 76% and 72% among male veterans. Women had higher odds of being diagnosed with a mental health disorder [adjusted odds ratio (AOR)=1.98; 95% confidence interval (CI), 1.68-2.34] and lower odds of being diagnosed with a substance use disorder (AOR=0.50; 95% CI, 0.45-0.56) compared with men. Women had lower odds of entering mental health residential treatment (AOR=0.69; 95% CI, 0.57-0.83).

CONCLUSIONS

Female veterans involved in the justice system have a high burden of mental health disorders (88%) and more than half have substance use disorders (58%). Entry to mental health residential treatment for women is an important quality improvement target.

Comorbidity and functional correlates of anxiety and physical conditions in Canadian Veterans

Introduction: Little is known about the relationship between anxiety disorders and physical conditions in Canadian Veterans. The purpose of this investigation was to examine the comorbidity of anxiety and physical conditions and their relation to physical and mental health–related quality of life and activity limitations in a nationally representative sample of Canadian Veterans. Methods: Participants were selected from the cross-sectional 2010 Survey on Transition to Civilian Life ( N = 3,154, response rate = 71.0%). The sample consisted of former Canadian Armed Forces Regular Force personnel who were released from 1998 to 2007. Multivariate logistic and linear regression models evaluated associations between several commonly occurring chronic physical conditions and any anxiety disorder and correlates (i.e., quality of life and activity limitations) of comorbidity. Results: Any anxiety disorder was associated with significantly elevated rates of cardiovascular, gastrointestinal, respiratory, and musculoskeletal conditions; diabetes; and chronic pain after controlling for sociodemographics, military characteristics, any mood disorder, and heavy drinking. However, when additionally controlling for number of physical conditions, any anxiety disorder remained significantly associated with gastrointestinal conditions (adjusted odds ratio [AOR] = 1.63, 99% confidence interval [CI] = 1.07–2.50) and chronic pain (AOR = 1.79, 99% CI = 1.15–2.78). Co-occurring anxiety disorders and musculoskeletal conditions were associated with poorer physical health–related quality of life and activity limitations than musculoskeletal conditions alone. Conclusion: Anxiety disorders and physical health problems co-occur at high rates among Canadian Veterans, and this comorbidity is linked to poorer physical health–related quality of life and activity limitations. These findings have implications for supporting at-risk personnel with the transition to civilian life and for informing health promotion and prevention efforts.

Prevalence of depression after spinal cord injury: a meta-analysis

OBJECTIVES

To use meta-analysis to synthesize point prevalence estimates of depressive disorder diagnoses for persons who have sustained a spinal cord injury (SCI).

DATA SOURCES

We searched PsycINFO, PubMed, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Dissertation Abstracts International (DAI) for studies examining depression after SCI through 2013. We also conducted a manual search of the reference sections of included studies.

STUDY SELECTION

Included studies contained persons with SCI; used a diagnostic measure of depression (ie, an unstructured, semi-structured, or structured clinical interview, and/or a clinician diagnosis); and provided a diagnosis of major or minor depressive episodes for the subjects in the study. Diagnostic criteria were based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, or the Diagnostic and Statistical Manual of Mental Disorders-Third Edition (including Research Diagnostic Criteria) criteria.

DATA EXTRACTION

The 2 authors of this study screened the titles and abstracts of 1053 unique studies for inclusion in this meta-analysis. Nineteen studies, containing 35,676 subjects and 21 effect size estimates, were included.

DATA SYNTHESIS

The mean prevalence estimate of depression diagnosis after SCI was 22.2%, with a lower-bound estimate of 18.7% and an upper bound estimate of 26.3%. Random effects and mixed effects models were used in this work. A small number of study moderators were explored, including sample sex composition, Diagnostic and Statistical Manual of Mental Disorders version used, data collection method (primary vs secondary), sample traumatic etiology composition, sample injury level and completeness composition, and sample diagnostic composition. Data collection method, Diagnostic and Statistical Manual of Mental Disorders version, and diagnostic composition significantly predicted variation in observed effect size estimates, with primary data collection studies having lower estimates compared with secondary data analysis studies, studies using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnostic criteria having higher estimates compared with studies using Diagnostic and Statistical Manual of Mental Disorders, Third Edition, criteria, and samples comprising individuals diagnosed only with major depression having lower prevalence estimates.

CONCLUSIONS

The existing data on depression after SCI indicate that the prevalence of depression after SCI is substantially greater than that in the general medical population. These results underscore the importance of continued research on measuring depression in persons with SCI and on treatments for depression after SCI.

Depression, healthcare utilization, and comorbid psychiatric disorders after spinal cord injury

BACKGROUND

Depression is often comorbid with other psychiatric conditions in the general population, with resultant impact on severity of conditions and healthcare utilization. It is unclear to what degree this is also true among persons with spinal cord injury (SCI).

OBJECTIVE

This study examined rates at which psychiatric conditions were comorbid with depression after SCI, and the association between a depression diagnosis and healthcare and pharmaceutical drug use.

METHODS

Retrospective analysis of data (N = 41 213) abstracted from Veterans Health Administration administrative databases between fiscal years (FYs) 1997 and 2007 to examine overall rates of depression. Administrative data from FY 2007 was used to examine rates of psychiatric disorders comorbid with depression, and to compare veterans with SCI and depression to veterans with SCI but no depression on healthcare and pharmaceutical use.

RESULTS

Twenty-eight percent (n = 11 506) of 41 213 veterans who received SCI care between FY 1997 and FY 2007 were diagnosed with depressive disorders. Among the veterans with SCI and depression diagnoses in 2007 (n = 2615), 70% were also diagnosed with another psychiatric illness, with posttraumatic stress disorder and other anxiety disorders being the most common. Veterans with SCI and depression had more healthcare visits and received more pharmaceutical prescriptions than their counterparts without depression.

CONCLUSIONS

Persons with SCI and depression are likely to experience comorbid psychiatric illnesses, with associated increased healthcare visits and medication use. Research and theory on depression after SCI should develop toward describing and addressing psychiatric and medical co-morbidities that are normative in this population.

Tissue engineering is a promising method for the repair of spinal cord injuries (Review)

Spinal cord injury (SCI) may lead to a devastating and permanent loss of neurological function, which may place a great economic burden on the family of the patient and society. Methods for reducing the death of neuronal cells, inhibiting immune and inflammatory reactions, and promoting the growth of axons in order to build up synapses with the target cells are the focus of current research. Target cells are located in the damaged spinal cord which create a connect with the scaffold. As tissue engineering technology is developed for use in a variety of different areas, particularly the biomedical field, a clear understanding of the mechanisms of tissue engineering is important. This review establishes how this technology may be used in basic experiments with regard to SCI and considers its potential future clinical use.

Training professionals’ communication and motivation skills to improve spinal cord injury patients’ satisfaction and clinical outcomes: Study protocol of the ESPELMA trial

Acute spinal cord injury leaves patients severely impaired and generates high levels of psychological distress among them and their families, which can cause a less active role in rehabilitation, worse functional recovery, and less perceived satisfaction with the results. Additionally, rehabilitation professionals who deal with this psychological distress could ultimately experience higher stress and more risk of burnout. This article presents the study protocol of the ESPELMA project, aimed to train rehabilitation professionals in the clinical management of acute spinal cord injury–associated psychological distress, and to measure the impact of this training on the patients’ perceived satisfaction with treatment.

Neuropsychological Assessment and Treatment Following a Spinal Cord Injury and Alcohol Withdrawal

Mr. Wellington, a 61-year-old veteran, was referred for a neuropsychological assessment and mental health treatment by his attending physician and psychologist following a spinal cord injury (SCI) and alcohol withdrawal. According to the referral, Mr. Wellington had been experiencing anxiety and depressive symptoms, as well as diminished cognitive functioning. These symptoms were considered to be interfering with his participation in SCI rehabilitation. Prior to the assessment, Mr. Wellington had sustained a tetraplegic injury due to a syrinx and partial L5 injury caused by an uncontrolled chronic bone infection and was receiving treatment at a Veteran’s Administration medical center. Results of the assessment, the related challenges in identifying the etiology of the patient’s diminished neurocognitive functioning, and mental health treatment are discussed.

Pain and post-traumatic stress disorder symptoms during inpatient rehabilitation among operation enduring freedom/operation iraqi freedom veterans with spinal cord injury

OBJECTIVE

To examine the frequency of post-traumatic stress disorder (PTSD) symptoms and pain, and how PTSD symptoms were associated with pain severity ratings and the longitudinal course of pain during inpatient rehabilitation for spinal cord injury (SCI) among veterans of the Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) conflicts.

DESIGN

Longitudinal analysis of data gathered from electronic medical records.

SETTING

SCI specialty care centers within the Department of Veterans Affairs.

PARTICIPANTS

Veterans of the OEF/OIF conflicts (N=87) who received inpatient rehabilitation for SCI and disorders at Department of Veterans Affairs SCI centers between May 2003 and October 2009.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE(S)

PTSD screening at start of rehabilitation and pain numeric rating scale measurements completed throughout rehabilitation. Cut-scores were used to categorize participants into 1 of 4 groups on the basis of scores at the start of rehabilitation: Pain and PTSD, Pain Alone, PTSD Alone, Neither Condition.

RESULTS

Comorbid pain and PTSD symptoms were more common than either condition alone, and nearly as common as not having either condition. Participants with pain at the start of rehabilitation (Pain and PTSD, Pain-Alone groups) showed declines in pain ratings over the course of rehabilitation. In contrast, participants in the PTSD-Alone group showed increasing pain over the course of rehabilitation.

CONCLUSIONS

Pain and PTSD symptoms may be more likely to manifest as comorbidities than as isolated conditions during inpatient rehabilitation. Assessment routines and care plans should be prepared with comorbidities as a foremost concern. It is advisable to screen for pain and PTSD at multiple time points during inpatient rehabilitation to detect new or emerging concerns.

Trends in probable PTSD in firefighters exposed to the World Trade Center disaster, 2001-2010

OBJECTIVE

We present the longest follow-up, to date, of probable posttraumatic stress disorder (PTSD) after the 2001 terrorist attacks on the World Trade Center (WTC) in New York City firefighters who participated in the rescue/recovery effort.

METHODS

We examined data from 11,006 WTC-exposed firefighters who completed 40,672 questionnaires and reported estimates of probable PTSD by year from serial cross-sectional analyses. In longitudinal analyses, we used separate Cox models with data beginning from October 2, 2001, to identify variables associated with recovery from or delayed onset of probable PTSD.

RESULTS

The prevalence of probable PTSD was 7.4% by September 11, 2010, and continued to be associated with early arrival at the WTC towers during every year of analysis. An increasing number of aerodigestive symptoms (hazard ratio [HR] 0.89 per symptom, 95% confidence interval [CI] 0.86-.93) and reporting a decrease in exercise, whether the result of health (HR 0.56 vs no change in exercise, 95% CI 0.41-.78) or other reasons (HR 0.76 vs no change in exercise, 95% CI 0.63-.92), were associated with a lower likelihood of recovery from probable PTSD. Arriving early at the WTC (HR 1.38 vs later WTC arrival, 95% CI 1.12-1.70), an increasing number of aerodigestive symptoms (HR 1.45 per symptom, 95% CI 1.40-1.51), and reporting an increase in alcohol intake since September 11, 2001 (HR 3.43 vs no increase in alcohol intake, 95% CI 2.67-4.43) were associated with delayed onset of probable PTSD.

CONCLUSIONS

Probable PTSD continues to be associated with early WTC arrival even 9 years after the terrorist attacks. Concurrent conditions and behaviors, such as respiratory symptoms, exercise, and alcohol use also play important roles in contributing to PTSD symptoms.

A longitudinal study of depression from 1 to 5 years after spinal cord injury

OBJECTIVE

To describe rates of probable major depression and the development and improvement of depression and to test predictors of depression in a cohort of participants with spinal cord injury (SCI) assessed at 1 and 5 years after injury.

DESIGN

Longitudinal cohort study.

SETTING

SCI Model System.

PARTICIPANTS

Participants (N=1035) who completed 1- and 5-year postinjury follow-up interviews from 2000 to 2009.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

Probable major depression, defined as Physician Health Questionnaire-9 score of 10 or higher.

RESULTS

Probable major depression was found in 21% of participants at year 1 and 18% at year 5. Similar numbers of participants had improvement (25%) or worsening (20%) of symptoms over time, with 8.7% depressed at both 1 and 5 years. Increased pain (odds ratio [OR], 1.10), worsening health status (OR, 1.39), and decreasing unsafe use of alcohol (vs no unsafe use of alcohol; OR, 2.95) are risk factors for the development of depression at 5 years. No predictors of improvement in depression were found.

CONCLUSION

In this sample, probable major depression was found in 18% to 21% of participants 1 to 5 years after injury. To address this high prevalence, clinicians should use these risk factors and ongoing systematic screening to identify those at risk for depression. Worsening health problems and lack of effective depression treatment in participants with SCI may contribute to high rates of chronic or recurrent depression in this population.

Preinjury alcohol and drug use among persons with spinal cord injury: implications for rehabilitation

CONTEXT/OBJECTIVE

To describe preinjury alcohol and drug use and opportunities for secondary prevention among persons with recent spinal cord injury (SCI).

DESIGN

Survey.

SETTING

Acute inpatient rehabilitation program.

PARTICIPANTS

Participants were 118 (84.8%) of 139 consecutive admissions who met inclusion criteria and were screened for preinjury alcohol and drug use.

INTERVENTIONS

None.

OUTCOME MEASURES

Alcohol and drug use, toxicology results, alcohol problems, readiness to change, and treatment preferences.

RESULTS

Participants were on average 37 years old, 84% were men, and 85% were white. Fifty-one percent of the sample was considered 'at-risk' drinkers. Significant lifetime alcohol-related problems were reported by 38% of the total sample. Thirty-three percent reported recent illicit drug use and 44% of the 82 cases with toxicology results were positive for illicit drugs. Seventy-one percent of at-risk drinkers reported either considering changes in alcohol use or already taking action. Forty-one percent reported interest in trying substance abuse treatment or Alcoholics Anonymous (AA). Motivation to change alcohol use was significantly and positively associated with self-reported indicators of alcohol problem severity.

CONCLUSION

Preinjury alcohol and drug abuse are common among persons with recent SCI. Substance abuse screening is feasible and detects not only salient clinical problems but also significant motivation to change and interest in AA or treatment, all of which represent an important window of opportunity for appropriate brief interventions and referrals. In contrast with the idea that alcoholism is a 'disease of denial', the majority of at-risk drinkers with new onset SCI indicate they are considering making changes.
