Studying depression following spinal cord injury: Evidence, policy and practice

Factors associated with multiple hospital readmissions for individuals with spinal cord injury

Objective

To identify patient-level and clinical factors associated with multiple hospital readmissions in individuals with spinal cord injury (SCI).

Design

Retrospective cohort analysis of the publicly available dataset from the SCI Rehabilitation (SCIRehab) study.

Setting

Six rehabilitation centers in the U.S. that participated in the SCIRehab study. Participants: Individuals with traumatic SCI (N=1371) who were consecutively enrolled in the SCIRehab study.

Outcome measures

The primary outcome was all-cause hospital readmission within 1 year of discharge from a rehabilitation center. The patient-level and clinical factors include employment status, depression, caregiver support, state-funded insurance, functional status, and rehabilitation services.

Results

Of the 1170 participants included in the study, 228 were readmitted once and 120 were readmitted multiple times. In our study, 34.2% and 10.8% were readmitted more than once due to genitourinary and respiratory conditions, respectively. Lower utilization of rehabilitation services, lower functional status, unemployment, and depression were associated with higher odds of being readmitted multiple times within one year of discharge from inpatient rehabilitation facility.

Conclusion

Psychosocial and clinical factors were associated with increased risk for multiple readmissions in individuals with SCI. In order to reduce recurrent readmissions in individuals with SCI, further research is necessary to maximize efficacy of risk factor modification and prevention strategies.

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.

The Patient Health Questionnaire depression screener in spinal cord injury

CONTEXT

Although depression is not inevitable following spinal cord injury/dysfunction (SCI/D), it can have a negative impact on rehabilitation. Evidence-based assessment of depression utilizing self-report instruments, such as the Patient Health Questionnaire-9 (PHQ-9), is considered good clinical practice. Although the PHQ-9 has been studied in individuals with SCI/D, little is known about the clinical utility of the Patient Health Questionnaire-2 (PHQ-2). Traditional cutoff scores for the PHQ-2 were examined to explore their operating characteristics as related to PHQ-9 results.

METHODS

Archival data were collected for 116 Veterans with SCI/D who completed the PHQ-2 and PHQ-9 as one component of their routine, comprehensive SCI annual evaluation at a Veterans Affairs Medical Center. Logistic regressions were performed to determine the impact of different cutoff scores for the PHQ-2 on the likelihood that participants would endorse clinically significant levels of depressive symptoms on the PHQ-9 (≥10).

RESULTS

Using a cutoff score of 3 or greater correctly classified 94.8% of the cases, outperforming the other cutoff scores. A cutoff score of 3 or greater had a sensitivity of 83.3% and specificity of 97.8%, and yielded a positive predictive value of 90.9% and a negative predictive value of 95.7%.

CONCLUSION

The PHQ-2 shows promise as a clinically useful screener in the community-residing SCI/D population. Findings regarding the presence of suicidal ideation emphasize the importance of routine screening for depressive symptomatology in the SCI/D population. Future research should investigate the role of the PHQ-2 in clinical decision-making and treatment monitoring.
