Relationship Between Substance Use and the Onset of Spinal Cord Injuries: A Medical Chart Review

Association of Disability Status and Type With Binge Drinking and Prescription Opioid Misuse Among Adults From a 3-State Sample

BACKGROUND

Research examining at-risk substance use by disability status is limited, with little investigation into differences by disability type. We investigated binge drinking and prescription opioid misuse among adults with and without disabilities, and by type of disability, to inform need for assessment and intervention within these populations.

METHODS

Secondary analyses of adults who completed the disability, alcohol, and prescription opioid misuse items in the 2018 Ohio, Florida, or Nebraska Behavioral Risk Factor Surveillance System surveys (n = 28 341), the only states that included prescription opioid misuse in 2018. Self-reported disability status (yes/no) relied on 6 standardized questions assessing difficulties with: vision, hearing, mobility, cognition, self-care, and independent living (dichotomous, nonmutually exclusive, for each disability). Logistic regression models estimated the association of disability status and type with (1) past 30-day binge drinking and (2) past-year prescription opioid misuse. Additional models were restricted to separate subsamples of adults who: (a) currently drink, (b) received a past-year prescription opioid, and (c) did not receive a past-year prescription opioid.

RESULTS

One-third reported at least one disability, with mobility (19.5%), cognitive (11.5%), and hearing (10.2%) disability being the most common. Disability status was associated with lower odds of binge drinking (adjusted odds ratio [AOR] = 0.74, 95% confidence interval [CI] 0.68-0.80, P ≤ .01). However, among adults who currently drink, people with disabilities had higher odds of binge drinking (AOR = 1.11, 95% CI 1.01-1.22, P ≤ .05]. Disability was associated with higher odds of past-year prescription opioid misuse (AOR = 2.51, 95% CI 2.17-2.91, P ≤ .01).

CONCLUSIONS

Adults with disabilities had higher odds of prescription opioid misuse, and among adults who currently drink, higher odds for binge drinking were observed. The magnitude of the association between disability status and prescription opioid misuse was particularly concerning. Providers should be trained to screen and treat for substance use problems for people with disabilities.

Blood Alcohol Concentration Is Associated With Improved AIS Motor Score After Spinal Cord Injury

Objective

To investigate the relationship between blood alcohol concentration (BAC) and neurologic recovery after traumatic spinal cord injury (TSCI) using standardized outcome measures from the International Standards for the Neurological Classification of Spinal Cord Injury (ISNCSCI) examination.

Method

This is a retrospective review of merged, prospectively collected, multicenter data from the Spinal Cord Injury Model Systems Database and institutional trauma databases from five academic medical centers across the United States. Patients with SCI and a documented BAC were analyzed for American Spinal Injury Association Impairment Scale (AIS) motor score, FIM, sensory light touch score, and sensory proprioception score upon admission and discharge from rehabilitation. Linear regression was used for the analysis.

Results

The study identified 210 patients. Mean age at injury was 47 ± 20.5 years, 73% were male, 31% had an AIS grade A injury, 56% had ≥1 comorbidity, mean BAC was 0.42 ± 0.9 g/dL, and the mean Glasgow Coma Score upon arrival was 13.27 ± 4.0. ISNCSCI motor score gain positively correlated with higher BAC (4.80; confidence interval [CI], 2.39-7.22; p < .0001). FIM motor gain showed a trend toward correlation with higher BAC, although it did not reach statistical significance (3.27; CI, -0.07 to 6.61; p = .055). ISNCSCI sensory light touch score gain and sensory proprioception score gain showed no correlation with BAC (p = .44, p = .09, respectively).

Conclusion

The study showed a positive association between higher BAC and neurologic recovery in patients with SCI as measured by ISNCSCI motor score gain during rehabilitation. This finding has not been previously reported in the literature and warrants further study to better understand possible protective physiological mechanisms underlying the relationship between BAC and SCI.

The Therapeutic Potential and Usage Patterns of Cannabinoids in People with Spinal Cord Injuries: A Systematic Review

BACKGROUND

People with spinal cord injuries (SCI) commonly experience pain and spasticity; limitations of current treatments have generated interest in cannabis as a possible therapy.

OBJECTIVES

We conducted this systematic review to: 1) examine usage patterns and reasons for cannabinoid use, and 2) determine the treatment efficacy and safety of cannabinoid use in people with SCI.

METHODS

PubMed, Embase, Web of Science and Cumulative Index to Nursing and Allied Health Literature databases were queried for keywords related to SCI and cannabinoids.

RESULTS

7,232 studies were screened, and 34 were included in this systematic review. Though 26 studies addressed cannabinoid usage, only 8 investigated its therapeutic potential on outcomes such as pain and spasticity. The most common method of use was smoking. Relief of pain, spasticity and recreation were the most common reasons for use. A statistically significant reduction of pain and spasticity was observed with cannabinoid use in 83% and 100% of experimental studies, respectively. However, on examination of randomized control trials (RCTs) alone, effect sizes ranged from - 0.82 to 0.83 for pain and -0.95 to 0.09 for spasticity. Cannabinoid use was associated with fatigue and cognitive deficits.

CONCLUSION

Current evidence suggests that cannabinoids may reduce pain and spasticity in people with SCI, but its effect magnitude and clinical significance are unclear. Existing information is lacking on optimal dosage, method of use, composition and concentration of compounds. Long-term, double-blind, RCTs, assessing a wider range of outcomes should be conducted to further understand the effects of cannabinoid use in people with SCI.
