Spinal Cord 2023; 61:430-435. [PMID: 36854965 PMCID: PMC10767623 DOI: 10.1038/s41393-023-00882-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Revised: 02/06/2023] [Accepted: 02/14/2023] [Indexed: 03/02/2023]
Abstract
STUDY DESIGN Cohort study. OBJECTIVE To identify five-year longitudinal changes in employment, health, participation, and quality-of-life outcomes (QOL) among participants with chronic spinal cord injury (SCI) and to compare the amount of change in these outcomes between those surviving and those not surviving until follow-up. METHODS Participants were 1157 individuals from the SCI Longitudinal Aging Study, who have completed at least two self-report assessments separated by five-year intervals. The main outcome measures were 13 indicators related to employment, health, participation, and QOL/psychosocial indicators. Survival status measured at follow-up. RESULTS Those who survived to follow up had a history indicating a greater likelihood of employment, better health, participation, and QOL/psychosocial indicators. Among survivors, longitudinal declines were limited to the percent employed and participation indicators, whereas those deceased by follow-up had significant undesirable changes in employment, participation, health, and QOL/psychosocial indicators. More specifically, compared to the survivors, those deceased by follow-up experienced a greater increase in hospitalizations, decreases in nights away from home, and declines in global satisfaction over the five-year interval. CONCLUSIONS Longitudinal declines in employment and some aspects of participation are common among long-term survivors and may be part of the natural course of outcomes after SCI. However, more dramatic increases in hospitalizations, fewer nights away from home, and declining satisfaction may be red flags for declining longevity.

Abstract
Background Individuals with traumatic spinal cord injuries (SCIs) have lower subjective well-being and diminished longevity, yet there is a lack of research on how life satisfaction and changes in life satisfaction relate to longevity. Objectives To identify the relationships between survival status and life satisfaction and its changing trend over a 10-year period. Methods Data were taken from the SCI Longitudinal Aging Study. A cohort study of 676 adult participants with SCI completed three assessments separated by 5-year intervals. We applied the survival analyses by using person-year logistic regression models. Results There were 135 participants (20%) who were deceased by the end of 2019. After controlling for demographic and injury factors, life satisfaction was significantly related to survival. In the final model, having an upward trend of life satisfaction was significantly associated with lower odds of mortality, whereas a downward trend in life satisfaction was not significant. Conclusion Our findings demonstrate the importance of current life satisfaction and having a trend toward improving satisfaction to survival. The findings indicated the importance of psychosocial adaptation to life quality and longevity after SCI.

Abstract
OBJECTIVE Mechanism of injury is a largely understudied descriptor of acute traumatic spinal cord injury (tSCI). This study sought to compare the impact of high-energy and low-energy mechanisms of injury in neurological outcomes of cervical sensorimotor complete tSCI. METHODS Patients with tSCI were identified in 4 prospective, multicenter clinical trials and registries. American Spinal Injury Association Impairment Scale (AIS) grade was assessed ≤ 72 hours postinjury and followed up between 12 to 52 weeks. Patients were included if they had a cervical and sensorimotor complete (AIS-A) injury at baseline. Study outcomes were change in AIS grade and lower extremity motor, upper extremity motor, and total motor scores. Propensity score matching between high-energy mechanisms of injury (HEMI; e.g. , motor vehicle collisions) and low-energy mechanisms of injury (LEMI; e.g. , falls) groups was performed. Adjusted groups were compared with paired t-tests and McNemar test. RESULTS Of 667 patients eligible for inclusion, 523 experienced HEMI (78.4%). HEMI patients were younger, had lower body mass index, more associated fractures or dislocations, and lower baseline lower extremity motor scores. After propensity score matching of these baseline variables, 118 pairs were matched. HEMI patients had a significantly worse motor recovery from baseline to follow-up based on their diminished change in upper extremity motor scores and total motor scores. CONCLUSION Cervical sensorimotor complete tSCIs from HEMI were associated with significantly lower motor recovery compared to LEMI patients. Our findings suggest that mechanism of injury should be considered in modelling prognosis and in understanding the heterogeneity of outcomes after acute tSCI.

Abstract
STUDY DESIGN Cohort study. OBJECTIVE Previous research has indicated that socioeconomic factors affect longevity after traumatic spinal cord injury (SCI). Our purpose was to evaluate whether social participation mediates the relationship between socioeconomic factors and survival status after SCI. SETTING Medical university in the southeastern United States. METHODS Participants (N = 1540) met the following inclusion criteria: traumatic SCI of at least 1-year duration, minimum of 18 years of age, and having residual impairment from SCI. The main outcome measures were a) survival status as of December 31, 2019, identified by the National Death Index (NDI) search, b) socioeconomic status (SES), measured by education, employment status, and family income, and c) participation, measured by marital/relationship status, hours out of bed per day, days leaving home per week, and nights away home during the past year. RESULTS Thirty nine percent of participants (n = 602) were decreased by the end of 2019. Socioeconomic factors were associated with longevity controlling for demographic, injury characteristics, and health status. However, the association of SES with longevity was mediated by three social participation mobility indicators (hours out of bed, days out of house, and nights away from home), such that SES was no longer significantly related to longevity after inclusion of the participation variables. CONCLUSIONS Although socioeconomic factors are related to longevity, their relationship appears to be mediated by social participation mobility indicators. Intervention studies are needed to address the modifiable factors that may promote longevity, including promoting an active lifestyle.

Abstract
Spinal cord injury (SCI) is a devastating condition that results in severe motor, sensory, and autonomic dysfunction. The L-/T-type calcium channel blocker nimodipine (NMD) exerts a protective effect on neuronal injury; however, the protective effects of long-term administration of NMD in subjects with SCI remain unknown. Thus, the aim of this study was to evaluate the role of long-term treatment with NMD on a clinically relevant SCI model. Female rats with SCI induced by 25 mm contusion were subcutaneously injected with vehicle or 10 mg/kg NMD daily for six consecutive weeks. We monitored the motor score, hind limb grip strength, pain-related behaviors, and bladder function in this study to assess the efficacy of NMD in rats with SCI. Rats treated with NMD showed improvements in locomotion, pain-related behaviors, and spasticity-like symptoms, but not in open-field spontaneous activity, hind limb grip strength or bladder function. SCI lesion areas and perilesional neuronal numbers, gliosis and calcitonin gene-related peptide (CGRP+) fiber sprouting in the lumbar spinal cord and the expression of K+–Cl− cotransporter 2 (KCC2) on lumbar motor neurons were also observed to further explore the possible protective mechanisms of NMD. NMD-treated rats showed greater tissue preservation with reduced lesion areas and increased perilesional neuronal sparing. NMD-treated rats also showed improvements in gliosis, CGRP+ fiber sprouting in the lumbar spinal cord, and KCC2 expression in lumbar motor neurons. Together, these results indicate that long-term treatment with NMD improves functional recovery after SCI, which may provide a potential therapeutic strategy for the treatment of SCI.

SSM Popul Health 2021; 15:100854. [PMID: 34258374 PMCID: PMC8259327 DOI: 10.1016/j.ssmph.2021.100854] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Revised: 06/21/2021] [Accepted: 06/21/2021] [Indexed: 12/20/2022] Open
Abstract
Income and health are related in a bi-directional manner, whereby level of income affects health and vice versa. People in poorer households tend to experience worse health status and higher mortality rates than people in wealthier households, and, at the same time, having poor health could restrict workability leading to less income. This gap exists in almost every country, and it is more pronounced in more unequal countries and in vulnerable populations, such as people experiencing disability. The goal of this paper is to estimate the health-income gap in people with a Spinal Cord Injury (SCI), which is a chronic health condition often associated with multiple comorbidities that leads to disability. As data on mortality is inexistent, to estimate the health-income gap for persons with SCI, this paper uses two health outcomes: the number of years a person has lived with the injury, and a comorbidity index. Data was obtained from the International Spinal Cord Injury survey (InSCI), which is the first worldwide survey on community-dwelling persons with SCI. To compare across countries, the health outcomes were adjusted through hierarchical models, accounting for country fixed-effects, individual characteristics such as age and gender, and injury characteristics (cause, type and degree). Our results suggest that for the years living with SCI, the gap varies from 1 to 6 years between the lowest and the highest income groups. The main driver of such a difference is the cause of injury, where injuries caused by work accidents showed the biggest gap. Similarly, for the comorbidity index, persons with SCI in poorer deciles reported significantly more comorbidities, forty times more, than people in richer deciles.

Abstract
Spasticity, one of the most frequent comorbidities of spinal cord injury (SCI), disrupts motor recovery and quality of life. Despite major progress in neurorehabilitative and pharmacological approaches, therapeutic strategies for treating spasticity are lacking. Here, we show in a mouse model of chronic SCI that treatment with nimodipine-an L-type calcium channel blocker already approved from the European Medicine Agency and from the U.S. Food and Drug Administration-starting in the acute phase of SCI completely prevents the development of spasticity measured as increased muscle tone and spontaneous spasms. The aberrant muscle activities associated with spasticity remain inhibited even after termination of the treatment. Constitutive and conditional silencing of the L-type calcium channel CaV1.3 in neuronal subtypes demonstrated that this channel mediated the preventive effect of nimodipine on spasticity after SCI. This study identifies a treatment protocol and suggests that targeting CaV1.3 could prevent spasticity after SCI.

Abstract
OBJECTIVE To evaluate whether pain interference mediates the relationship between pain intensity and probable major depression (PMD) among persons with spinal cord injury (SCI), accounting for differences in the frequency of prescription medication use and resilience. DESIGN Cross-sectional analysis using self-report assessment. SETTING Medical university in the Southeastern United States. PARTICIPANTS There were a total of 4670 participants (N=4670), all of whom had traumatic SCI of at least 1-year duration, identified from the Southeastern Regional SCI Model System and 2 state-based surveillance systems. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The Patient Health Questionnaire-9 was used to define PMD. Covariates included demographic and injury characteristics, pain severity, pain interference, and resilience. Separate sets of multistage logistic regression analyses were conducted for 3 levels of prescription pain medication use (daily, occasional/weekly, none). RESULTS Pain intensity was related to a greater risk of PMD (odds ratio [OR]daily pain medication user, 1.28; 95% confidence interval [CI], 1.21-1.35; ORoccasional/weekly pain medication user, 1.26; 95% CI, 1.16-1.36; ORnonpain medication user, 1.44; 95% CI, 1.33-1.56), but this relationship disappeared after consideration of pain interference (ORdaily pain medication user, 0.97; 95% CI, 0.90-1.04; ORoccasional/weekly pain medication user, 0.94; 95% CI, 0.84-1.05; ORnonpain medication user, 1.07; 95% CI, 0.95-1.20), which indicates pain interference was a mediator between pain intensity and PMD and there was no direct relationship between pain intensity and PMD. Resilience was protective of PMD in each model but was not a mediator. CONCLUSIONS Although pain intensity was associated with PMD, the relationship was mediated by pain interference. Resilience was an important protective factor. Therefore, clinicians should assess pain interference when screening for PMD and direct treatment at reducing pain interference. Building resilience may further reduce the risk of PMD.

Abstract
OBJECTIVE To evaluate how self-reported problems change over time among people with spinal cord injury (SCI). DESIGN Cross-sequential analysis. SETTING Medical university in the Southeastern United States. PARTICIPANTS Participants included 1997 individuals with traumatic SCI of at least 1-year duration who were identified from participation in the SCI Longitudinal Aging Study from 1993-2018. INTERVENTIONS None. MAIN OUTCOME MEASURES The outcomes analyzed were 6 problem factors defined as health, social isolation, emotional distress, environmental barriers, money, and lack of opportunities. A series of cross-sequential models, using PROC MIXED procedure, were developed to evaluate the initial and change of the 6 problem factors over the 6 times of measurements in 25 years. RESULTS Years post injury was negatively associated with initial status of problems of social isolation, emotional distress, environmental barriers, and lack of opportunities because participants with more years post injury at baseline reported lower scores on each factor. Longitudinally, with increased years post injury, higher scores were observed on the health problem factor. However, problems of social isolation, emotional distress, environmental barriers, money, and lack of opportunities decreased over time with increasing years post injury. CONCLUSIONS Participants had more health problems with increasing years after SCI, but fewer problems of social isolation, emotional distress, environmental barriers, money, and lack of opportunities.

Abstract
OBJECTIVE To identify the prevalence of opioid use in individuals with chronic spinal cord injury (SCI) living in South Carolina. DESIGN Cohort study. SETTING Data from 2 statewide population-based databases, an SCI Registry and the state prescription drug monitoring program, were linked and analyzed. PARTICIPANTS The study included individuals (N=503) with chronic (>1y) SCI who were injured between 2013 and 2014 in South Carolina and who survived at least 3 years postinjury. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Filled opioid prescriptions over a 2-year period (months 13-36 after injury). The main outcomes were total number of days with an opioid prescription over the 2-year period, length of coverage period [(final day of prescription coverage+the days supplied)-first day of prescription coverage], average daily morphine milligram equivalents (MME) over the coverage period, and concurrent days covered by an opioid and a prescription for benzodiazepines, sedatives, or hypnotics. RESULTS A total of 53.5% of the cohort (269 individuals) filled at least 1 opioid prescription during their second or third year after SCI. In total, there were 3386 opioid fills during the 2-year study. On average, the total number of opioid prescription days was 293±367. The average coverage period was 389±290 days, and the average daily MME during the coverage period was 41±70 MME. Of those who filled an opioid prescription, 23% had high-risk fills (>50 MME), and 38% had concurrent prescriptions for benzodiazepines, sedatives, or hypnotics. CONCLUSIONS The prevalence of opioid use was high among individuals with chronic SCI, exceeding rates observed in the general population. Also concerning were the rates of high-risk fills, based on average daily MME and concurrent benzodiazepine, sedative, or hypnotic prescriptions. These findings, taken together with those of earlier studies, should be used by providers to assess and monitor opioid use, decrease concurrent high-risk medication use, and attenuate the risk of adverse outcomes.

Abstract
Objective: Identify the association of personality and purpose in life with competing risks of multiple causes of death after spinal cord injury (SCI), using data from the SCI Longitudinal Health Study. Design: Prospective cohort study with data collected in 1997-1998 and 2007-2009. Mortality status determined as of December 31, 2016. Setting: Specialty hospital in the Southeastern United States. Participants: 3070 adults with chronic (>1-year), traumatic SCI. Interventions: N/A. Outcome Measures: We examined 6 psychological factors (Purpose in Life and 5 scales of the Zuckerman-Kuhlman Personality Questionnaire) and risk of mortality due to 6 specific causes of death, building on published analyses of behavioral and health/clinical risk and protective factors. Results: There were 803 deaths. Four of the 6 psychological factors were predictive of all-cause mortality. All except 1 personality scale were related to cause-specific mortality. Psychological factors were most predictive of unintentional injury deaths. Purpose in life was protective of death due to pneumonia; whereas, Activity was protective of death due to diseases of heart and blood vessels and to unintentional injury. Sociability, Impulsive-Sensation Seeking, and Neuroticism-Anxiety were risk factors for death due to unintentional injury. Neuroticism-Anxiety was related to death due to septicemia. There were no significant psychological predictors of cancer. Conclusions: Rehabilitation professionals have a central role in promoting purpose in life as a means of increasing longevity. By assessing personality factors predictive of specific causes of mortality, those at risk may be targeted for cause-specific prevention strategies.

Abstract
KEY POINTS Cutaneous reflexes were tested to examine the neuronal mechanisms contributing to muscle spasms in humans with chronic spinal cord injury (SCI). Specifically, we tested the effect of Achilles and tibialis anterior tendon vibration on the early and late components of the cutaneous reflex and reciprocal Ia inhibition in the soleus and tibialis anterior muscles in humans with chronic SCI. We found that tendon vibration reduced the amplitude of later but not earlier cutaneous reflex in the antagonist but not in the agonist muscle relative to the location of the vibration. In addition, reciprocal Ia inhibition between antagonist ankle muscles increased with tendon vibration and participants with a larger suppression of the later component of the cutaneous reflex had stronger reciprocal Ia inhibition from the antagonistic muscle. Our study is the first to provide evidence that tendon vibration attenuates late cutaneous spasm-like reflex activity, likely via reciprocal inhibitory mechanisms, and may represent a method, when properly targeted, for controlling spasms in humans with SCI. ABSTRACT The neuronal mechanisms contributing to the generation of involuntary muscle contractions (spasms) in humans with spinal cord injury (SCI) remain poorly understood. To address this question, we examined the effect of Achilles and tibialis anterior tendon vibration at 20, 40, 80 and 120 Hz on the amplitude of the long-polysynaptic (LPR, from reflex onset to 500 ms) and long-lasting (LLR, from 500 ms to reflex offset) cutaneous reflex evoked by medial plantar nerve stimulation in the soleus and tibialis anterior, and reciprocal Ia inhibition between these muscles, in 25 individuals with chronic SCI. We found that Achilles tendon vibration at 40 and 80 Hz, but not other frequencies, reduced the amplitude of the LLR in the tibialis anterior, but not the soleus muscle, without affecting the amplitude of the LPR. Vibratory effects were stronger at 80 than 40 Hz. Similar results were found in the soleus muscle when the tibialis anterior tendon was vibrated. Notably, tendon vibration at 80 Hz increased reciprocal Ia inhibition between antagonistic ankle muscles and vibratory-induced increases in reciprocal Ia inhibition were correlated with decreases in the LLR, suggesting that participants with a larger suppression of later cutaneous reflex activity had stronger reciprocal Ia inhibition from the antagonistic muscle. Our study is the first to provide evidence that tendon vibration suppresses late spasm-like activity in antagonist but not agonist muscles, likely via reciprocal inhibitory mechanisms, in humans with chronic SCI. We argue that targeted vibration of antagonistic tendons might help to control spasms after SCI.

Abstract
STUDY DESIGN Prospective cohort study. OBJECTIVES Identify the risk and protective factors of all-cause and cause-specific mortality among persons with traumatic spinal cord injury (SCI). SETTING Rehabilitation specialty hospital in the Southeastern United States. METHODS A prospective cohort study was conducted with 3070 adults with traumatic SCI who were a minimum of 1 year post-injury at assessment. Prospective data were collected in 1997-1998 and 2007-2010, with mortality determined as of 31 December, 2016. The deceased were classified into six categories based on underlying cause of death: septicemia, pneumonia and influenza, cancer, heart and blood vessel diseases, unintentional injuries, and all other causes. The competing risk analysis strategy applied to each of the specific causes. RESULTS There were a total of 803 observed deaths among the 2979 final study sample. After controlling for demographic and injury characteristics, general health, pressure ulcer history, and symptoms of infections were significantly associated with all-cause mortality. Except for cancer, they were also related with at least one of the specific causes of death, whereas orthopedic complications and subsequent injuries were unrelated to any cause. CONCLUSIONS Three health domains, global health, pressure ulcers, and symptoms of illness or infection, were significantly associated with mortality after SCI, and the patterns of association varied as a function of specific cause of death.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES This study investigates the association between spinal cord injuries (SCI) and post-injury mortality. SUMMARY OF BACKGROUND DATA SCIs) are severe conditions treated in the acute trauma setting. Owing to neurological deficits, unstable spinal columns, and associated injuries, these patients often have complex inpatient hospitalizations with significant morbidity and mortality. It is assumed that a high rate of postinjury mortality would follow such severe injuries; however, the effect of SCI and its treatment on predictors of longevity remain largely unknown. METHODS Patients seen at a regional referral center for SCI were reviewed from a prospectively maintained database. Four hundred and twenty-six patients with SCI and varying degrees of injury between 2004 and 2009 were collected. Injury characteristics, including injury severity score, level of SCI, and type of SCI were retrieved. To determine independent predictors of 5-year mortality, a logistic regression using patient and injury characteristics at the time of presentation was performed. RESULTS Average age was 47.4 years (range: 14-95), and 74.5% (318/426) were male. Half of the cohort sustained low-energy mechanisms of injury (220/426; 52.4%). The 30-day, 90-day, 1-year, 2-year, and 5-year mortality rates in the SCI cohort were 6.6% (28/426), 9.2% (39/426), 12.0% (51/426), 15.0% (64/426), and 17.8%, respectively (76/426). Logistic regression demonstrated that increasing age (B = 1.06, P < 0.001), increasing ICU length-of-stay (B = 1.06; P = 0.002), decreased motor score at presentation (B = 0.98; P = 0.004), and lack of surgical intervention (B = 0.38; P < 0.001) were independent predictors of mortality at 5 years. CONCLUSION There is substantial mortality associated with SCI. A significant proportion of the mortalities occurred acutely after injury. Mortality was associated with neurological deficit and severity of injury, as well as with preinjury patient characteristics. To combat this high rate of death, efforts are needed to address the concomitant disease processes associated with neurological deficits. LEVEL OF EVIDENCE 3.

Abstract
STUDY DESIGN Prospective cohort study. OBJECTIVE To identify the relationship of frequency of prescription medication use to treat pain, spasticity, sleep, and depression/stress, and change in prescription medication use with risk of all-cause mortality. SETTING This study was initiated at a specialty hospital in the Southeastern USA, with follow-up and data analysis at an academic medical center in the Southeastern United States. METHODS Prospective data were collected in 1997-1998 (Time 1) and 2007-2009 (Time 2), with mortality determined as of 31 December 2014. The initial participant cohort was comprised of 1386 participants with traumatic SCI who were adults and a minimum of 1-year post-injury at enrollment in 1997-1998. Of these, 863 participated at follow-up and 861 were included in the current mortality analysis. RESULTS The frequency of taking prescription medication increased over the 10-year timeframe, particularly for sleep and pain. Each type of prescription medication at Time 1 was associated with later mortality, and an increase in medication use over time was associated with a greater risk of mortality for three of the four conditions (all except spasticity). A decrease in the frequency of pain medication use over time was associated with a decreased risk of all-cause mortality. CONCLUSIONS More frequent use of prescription medication to treat pain, sleep, and depression/stress is related to all-cause mortality, and increases in the use of medications to treat these conditions is associated with elevated risk of all-cause mortality.

Abstract
OBJECTIVE To determine whether antispasmodic medications are associated with neurological and functional outcomes during the first year after traumatic spinal cord injury (SCI). DESIGN/METHODS Retrospective analysis of prospectively collected data from six inpatient SCI rehabilitation centers. Baseline-adjusted outcomes at discharge and one-year follow-up were compared using analysis of covariance between patients who received antispasmodic medication on at least 5 days during inpatient rehabilitation and patients who did not. OUTCOME MEASURES Rasch-transformed motor subscore of the Functional Independence Measure (FIM); International Standards for Neurological Classification of Spinal Cord Injury motor scores, grade, and level. RESULTS Of 1,259 patients, 59.8%, 35.4%, and 4.8% were injured at the cervical, thoracic, and lumbosacral levels, respectively. 65.6% had motor complete injury. Rasch-transformed motor FIM score at admission averaged 23.3 (95% confidence interval (CI) 22.4-24.2). Total motor score averaged 39.2 (95% CI 37.8-40.6). 685 patients (54.4%) received one or more antispasmodic medications on at least 5 days. After controlling for demographic and injury variables at admission, Rasch-transformed motor FIM scores at discharge were significantly lower (P = 0.018) in patients receiving antispasmodic medications than in those who did not. This trend persisted in secondary analyses for cervical, thoracic, and lumbosacral subgroups. Multivariate regression showed that receiving antispasmodic medication significantly contributed to discharge motor FIM outcome. At one-year follow-up, no outcomes significantly differed between patients ON or OFF antispasmodics. CONCLUSIONS Antispasmodic medications may be associated with decreased functional recovery at discharge from inpatient traumatic SCI rehabilitation. Randomized prospective studies are needed to directly evaluate the effects of antispasmodic medication on recovery.

Abstract
PURPOSE The purpose of this study was to evaluate the impact of implementing evidence-based guidelines on smoking cessation in persons with spinal cord injuries and pressure injuries. We also evaluated the impact of smoking on pressure injury healing in this population. SUBJECTS AND SETTING The sample population included 158 spinal cord-injured patients with pressure injuries (29 females and 129 males). There were 83 in the control group and 75 in the intervention group, with a mean age of 44 years in both groups. The research setting was an outpatient wound clinic located in a large medical center in the southeastern United States. METHODS A retrospective chart review was completed. Data were reviewed 6 months before and 6 months after implementation of the US Department of Health and Human Services Clinical Practice Guidelines for Treating Tobacco Use and Dependence. We evaluated the number and size of wounds, achievement of smoking cessation, and demographic information. RESULTS Forty-eight percent of the control group participants and 57% of the intervention group participants smoked cigarettes at baseline. Smoking cessation doubled with the use of the clinical practice guidelines (P = .03). Smokers presented with a greater number of pressure injuries than nonsmokers. They experienced a mean increase rather than reduction in wound size. Nearly half (45.5%) of the intervention group participants who desired to have surgery had it performed, compared with only 34.9% of the control group participants (P = .35). CONCLUSIONS Our findings demonstrate a positive influence with use of clinical practice guidelines to help individuals stop smoking. Results also confirm findings of previous studies supporting the negative impact of smoking on pressure injury healing in persons with spinal cord injuries.

Abstract
OBJECTIVE To identify the association of pain intensity, pain interference, and pain medication use with risk of mortality after spinal cord injury, controlling for demographic, injury, socioeconomic, and health factors. DESIGN Prospective cohort study. SETTING Academic medical center. PARTICIPANTS All participants (N=2535) had traumatic spinal cord injury of at least 1-year duration at enrollment, with noncomplete recovery (American Spinal Injury Association Impairment Scale grades A-D). Mortality status was obtained for 2535 individuals, and 335 were deceased as of 2014. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Mortality status as of December 31, 2014, identified by the National Death Index. RESULTS Preliminary bivariate analyses indicated that deceased participants were more likely to be older at injury, have more years postinjury, be men, and have a severe injury, low income, less education, and poorer health indicators. The final Cox model indicated that those who used pain medication daily were 51% more likely to be deceased at follow-up (hazard ratio [HR], 1.51). Pain intensity and pain interference were not statistically significant. Nonchronic pressure ulcer was related to 67% higher mortality risk (HR, 1.67), and chronic pressure ulcer was related to 122% higher risk (HR, 2.22). Other health indicators also increased the risk of mortality from 43% to 73%, including hospitalization (HR, 1.54), depression (HR, 1.43), and amputation (HR, 1.73). CONCLUSIONS Prescription pain medication use appears to have a direct association with mortality, beyond that associated with other characteristics, and should become a strong focus of prevention efforts.

Abstract
Our purpose was to identify risk of pain medication misuse (PMM) among participants with spinal cord injury (SCI) by examining associations with multiple sets of risk factors including demographic and injury characteristics, pain experiences, frequency of pain medication use, substance use, personality, and depressive symptoms. Risk of PMM was defined by a cutoff score ≥30 measured using the Pain Medication Questionnaire (PMQ) and examined in 1,619 adults with traumatic SCI of at least 1 year duration who reported at least 1 painful condition and use of prescription pain medication using a cross-sectional design. Results indicated 17.6% of participants had scores of ≥30 on the PMQ. After controlling for demographic, injury, and pain characteristics, logistic regression analysis showed that being a current smoker, recently using cannabis (behavioral factors), and multiple psychological factors were associated with risk of PMM, as indicated by scores on the PMQ. These included elevated depressive symptomatology and exhibiting impulsive or anxious personality traits. Because risk of PMM is indicated in individuals with SCI, prescribers should assess and monitor multiple risk factors for PMM including substance use behaviors and psychological indicators. PERSPECTIVE This article identifies behavioral substance use and psychological factors associated with risk of PMM, measured using the PMQ, among those with SCI. Identification of these related variables will help health care professionals better prescribe and monitor pain medication use and/or misuse among individuals with SCI.

Abstract
OBJECTIVE To investigate the association of multiple sets of risk and protective factors (biographic and injury, socioeconomic, health) with cause-specific mortality after spinal cord injury (SCI). DESIGN Retrospective analysis of a prospectively created cohort. SETTING Spinal Cord Injury Model Systems facilities. PARTICIPANTS Adults (N=8157) with traumatic SCI who were enrolled in a model systems facility after 1973 and received follow-up evaluation that included all study covariates (between November 1, 1995 and October 31, 2006). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES All-cause mortality was determined using the Social Security Death Index as of January 1, 2014. Causes of death were obtained from the National Death Index and classified as infective and parasitic diseases, neoplasms, respiratory system diseases, heart and blood vessel diseases, external causes, and other causes. Competing risk analysis, with time-dependent covariates, was performed with hazard ratios (HRs) for each cause of death. RESULTS The HRs for injury severity indicators were highest for deaths due to respiratory system diseases (highest HR for injury level C1-4, 4.84) and infective and parasitic diseases (highest HR for American Spinal Injury Association Impairment Scale grade A, 5.70). In contrast, injury level and American Spinal Injury Association Impairment Scale grade were relatively unrelated to death due to neoplasms and external causes. Of the socioeconomic indicators, education and income were significantly predictive of a number of causes of death. Pressure ulcers were the only 1 of 4 secondary health condition indicators consistently related to cause of death. CONCLUSIONS Injury severity was related to mortality due to infective disease and respiratory complications, suggesting that those with the most severe SCI should be targeted for prevention of these causes. Socioeconomic and health factors were more broadly related to a number of causes of death. Intervention strategies that enhance socioeconomic status and health may also result in reduced mortality due to multiple causes.

Abstract
Background: Research has shown that employment following spinal cord injury (SCI) is related to health and functioning, with physical health and functioning after SCI frequently identified as a primary barrier to employment. Objective: To examine the relationship between employment and behaviors associated with the management of physical health and functioning as described by individuals with SCI who have been employed post injury. Methods: A qualitative approach using 6 focus groups at 2 sites included 44 participants with SCI who had worked at some time post injury. Heterogeneous and homogeneous groups were created based on specific characteristics, such as education, gender, or race. A semi-structured interview format asked questions about personal, environmental, and policy-related factors influencing employment after SCI. Groups were recorded, transcribed, and entered into NVivo before coding by 2 reviewers. Results: Within the area of behaviors and management of physical health and functioning, 4 overlapping themes were identified: (1) relearning your own body and what it can do; (2) general health and wellness behaviors; (3) communication, education, and advocacy; and (4) secondary conditions and aging. Specific themes articulate the many types of behaviors individuals must master and their impact on return to work as well as on finding, maintaining, and deciding to leave employment. Conclusions: Individuals with SCI who are successfully employed after injury must learn how to perform necessary behaviors to manage health and function in a work environment. The decision to leave employment often appears to be associated with secondary complications and other conditions that occur as persons with SCI age.

Abstract
STUDY DESIGN Self-reported survey. OBJECTIVE Our purpose was to identify the predictors of pain medication misuse (PMM) among participants with spinal cord injury (SCI). SETTING A medical university in the southeastern United States. METHODS A total of 919 adults with impairment from traumatic SCI of at least 1-year duration, who reported at least one painful condition and were taking prescription medication to treat pain, were included in this study. PMM was measured by the Pain Medication Questionnaire (PMQ). RESULTS The average PMQ score was 19.7, with 25.8% of participants scoring at or above the cutoff of 25, which is indicative of PMM. A three-stage logistic regression analysis was conducted by sequentially adding three sets of predictors to the equation: (1) demographic and injury characteristics; (2) pain characteristics and (3) frequency of pain medication use. Age and education level were protective of PMM, whereas pain intensity, pain interference and pain medication use were risk factors. Number of painful days was not significant in the final model. CONCLUSION PMM must be of concern after SCI, given its high prevalence among those with at least one painful condition and its relationship with pain indicators.

Abstract
OBJECTIVE To determine unique associations of suicidal ideation (SI) and lifetime suicide attempts (SAs) in individuals with spinal cord injury (SCI). DESIGN Cross-sectional analysis. SETTING Outpatient. PARTICIPANTS Individuals with SCI (N=2533) who were 18 years or older with a history of traumatic SCI. INTERVENTIONS None. MAIN OUTCOME MEASURES Any SI in the past 2 weeks (9-item Patient Health Questionnaire) and any lifetime SA. RESULTS Three hundred twenty-three individuals (13.3%) reported SI in the past 2 weeks and 179 (7.4%) reported lifetime SA. After controlling for other factors, both lifetime SA and current SI were associated with study site and current level of depression. In addition, SA was associated with less education, younger age at injury, having current or past treatment of depression, and having bipolar disorder or schizophrenia. SI was associated with more years since injury and lifetime SA. Several psychological factors were associated with current SI and lifetime SAs, including lower environmental reward and less positive affect. In addition, control of one's community activities and spiritual well-being were associated with current SI. In bivariate comparisons, severity of SCI was also associated with the 47% of the SAs that occurred after injury. CONCLUSIONS Several unique associations of SI and lifetime SA in individuals with SCI were identified, including level of environmental reward and control, spiritual well-being, and severity of SCI. These factors bear further investigation as prospective risk factors for suicidal behavior after SCI.

Abstract
OBJECTIVE To introduce allostatic load (AL) as a framework for measuring stress-related outcomes after spinal cord injury (SCI) by identifying the number and nature of biomarkers investigated in existing studies and by generating preliminary data on AL in 30 persons with traumatic SCI. METHODS This systematic review and pilot study were conducted at a medical university in the southeastern United States. A review of literature published between 1993 and 2012 identified studies using 2 or more of 5 classes of AL biomarkers. We then collected data on 11 biomarkers (n = 30) from self-selected participants using physical exams and blood and urine specimen collection. These included waist to hip ratio, systolic and diastolic blood pressure, total cholesterol, high-density lipoprotein cholesterol, dihydroepiandrosterone, glycosylated hemoglobin, C-reactive protein, interleukin-6, and cortisol, norepinephrine, and epinephrine normalized by 12-hour creatinine. RESULTS We were unable to identify any studies investigating AL biomarkers from each of the 5 areas or any studies specifically proposing to investigate AL. AL scores were relatively low, with metabolic indicators being the most elevated and neuroendocrine the least elevated. CONCLUSIONS AL is a promising, yet underutilized, construct that may be feasibly assessed after SCI.

Abstract
STUDY DESIGN Retrospective population-based study with mortality follow-up. OBJECTIVE To study mortality, causes and risk factors for death in Estonian patients with traumatic spinal cord injury (TSCI). SETTING All Estonian hospitals. METHODS Medical records of patients with TSCI from all regional, central, general, and rehabilitation hospitals in Estonia from 1997 to 2007, were retrospectively reviewed. Mortality status was ascertained as of 31 December 2011. Causes of death were collected from the Estonian Causes of Death Registry. Standardized mortality ratios (SMRs) were calculated for the entire sample and for causes of death. A Cox proportional hazards modeling was used to identify the risk indicators for death. RESULTS During the observation period (1997-2011) 162 patients of 595 died. Nearly half of the patients (n = 76) died during the first year after TSCI. The main causes of death were external causes (30%), cardiovascular disease (29%). and suicide (8%). The overall SMR was 2.81 (95% confidence interval 2.40-3.28) and SMR was higher for women than for men (3.80 vs. 2.70). Cause-specific SMRs were markedly elevated for sepsis and suicide. Mortality was significantly affected by the age at the time of injury, neurological level, and extent of the injury as well as the year of TSCI and complications. CONCLUSION Life expectancy is significantly decreased in patients with TSCI in Estonia compared with the general population. Deaths during the first year after the injury have an important impact on statistics. Treatment of cardiovascular diseases, infections, and prevention of suicide are useful for reducing mortality in patients with TSCI.

Abstract
INTRODUCTION Smoking, while detrimental to health in any population, has greater health implications for those with spinal cord injury (SCI) because of additional risks posed by SCI. The aims of this study were to document smoking status after SCI and to assess relationships between smoking status with injury severity and alcohol/pain medication use. METHODS Participants (n = 1,076) were identified from a large rehabilitation hospital in the southeastern part of the United States. Eligibility criteria included (a) traumatic SCI resulting in residual impairment, (b) adult, and (c) 1+ years postinjury. Previous and current cigarette smoking and quitting attempts were assessed. Relationships were assessed between smoking status (current, former, and never), alcohol use, and pain medication use. RESULTS Of participants (72% male, M age = 49.6 years, M = 16.1 years since SCI), 49.2% had never smoked, 28.2% were former smokers, and 22.6% were current smokers. Of current smokers, 39.2% attempted quitting in the past year and 77.2% had ever tried to quit. Only 29.9% of those who ever tried to quit sought professional help. Ambulatory persons, regardless of injury level, were 2.32 times more likely to be current smokers than nonambulatory persons with a high-level cervical injury. Lower socioeconomic status, binge drinking, and misuse of pain medication all predicted current smoking. CONCLUSIONS Smoking prevalence among persons with SCI is largely consistent with the general population. Additionally, we found smoking to be associated with other risk behaviors (binge drinking and prescription medication misuse) and differs by injury severity. Future studies should assess smoking interventions, which may differ by injury severity.

Abstract
BACKGROUND To successfully prevent secondary health conditions (SHCs) and promote longevity after spinal cord injury (SCI), we must first understand the risk factors precipitating their occurrence and develop strategies to address these risk factors. Conceptual models may aid in identifying the nature of SHCs and guide research, clinical practice, and the development of prevention strategies. OBJECTIVE Our purpose is to review and refine an existing theoretical risk and prevention model (TRPM) as a means of classifying risk and protective factors for SHCs and mortality after SCI and for identifying points of intervention. METHODS We describe conceptual work within the field of SCI research and SHCs, including a description of the TRPM, a review of research using the TRPM, and conceptual enhancements to the TRPM based on previous research. CONCLUSIONS The enhanced TRPM directs research to the timing and chronicity of the SHCs and their relationship with overall health and physiologic decline. Future research should identify differences in the nature of SHCs, the extent to which they relate to risk and protective factors, and the degree to which they may be prevented with appropriate research-based strategies.

Abstract
STUDY DESIGN Cohort study. OBJECTIVES First, to examine three sets of risk and protective factors for mortality after spinal cord injury (SCI), with an emphasis on health and secondary conditions. Second, to extend earlier work with several methodologic enhancements and addition of new predictors. SETTING Twenty hospitals designated as SCI Model Systems (SCIMSs) of care in the United States. METHODS Altogether, 8183 adults with traumatic SCI who received at least one follow-up evaluation between November 1995 and October 2006 from one of the SCIMSs were included in the study. There were 76,262 person-years and 1381 deaths at the end of June 2011. Mortality status determined by National Death Index and Social Security Death Index searches. Three successive sets of risk factors were evaluated with a logistic regression model on person-year observations to estimate the chance of dying in any given year. RESULTS Several biographic and injury, socio-environmental and health factors were significantly related to the odds of mortality. A history of pneumonia or kidney calculus was associated with greater odds of mortality, whereas deep vein thrombosis was not. Poor general health, decline in health over the past year, hospitalization and a grade 3 or 4 pressure ulcer were also related to mortality. Consistent with a mediating effect, odds ratios declined with the addition of each successive set of factors. CONCLUSION The relationship of biographic and injury characteristics with mortality after SCI is mediated by socio-environmental and health factors. Assessment of these variables enhances our ability to identify individuals at risk for excess mortality.

Abstract
BACKGROUND The primary purpose of this article is to provide an overview of demography, neurological level of injury, extent of lesion, incidence, prevalence, injury mechanisms as well as lethality and causes of death associated with traumatic spinal cord injuries. MATERIAL AND METHOD A literature search was carried out in PubMed, with the search words "traumatic spinal cord injury"/"traumatic spinal cord injuries" together with "epidemiology", and "spinal cord injury"/"spinal cord injuries" together with "epidemiology". RESULTS The reported annual incidence of traumatic spinal cord injuries varies from 2.3 per million in a study from Canada to 83 per million in Alaska. The prevalence is given as ranging from 236 per million in India to 1800 per million in the USA. The average age at the time of injury varies from 26.8 years in Turkey to 55.5 years in the USA. The ratio of men to women varies from 0.9 in Taiwan to 12.0 in Nigeria. The most frequent cause of injury is traffic accidents, followed by falls, violence and sports/leisure activity incidents. Patients with traumatic spinal cord injuries have a higher lethality than the normal population. The most frequent causes of death today are airway problems, heart disease and suicide. INTERPRETATION There are large geographical differences in reported incidence, prevalence and lethality. This is attributable to differences in definition, inclusion, classification and patient identification procedures in the various studies, together with geographical and cultural differences and differences in prehospital and hospital treatment.

Abstract
OBJECTIVE To examine behavioral risk factors in relation to fatigue after spinal cord injury (SCI), specifically cardiovascular-related behaviors, prescription medication use, and alcohol and cigarette use. DESIGN Cross-sectional. SETTING A medical university in the southeastern United States. PARTICIPANTS Adults (N=2245) at least 1 year post-SCI from a large specialty hospital in the Southeast responded to a mail-in survey. INTERVENTION Not applicable. MAIN OUTCOMES MEASURE The Modified Fatigue Impact Scale-5-item version was used to assess disabling fatigue. RESULTS Of participants, 8.3% had disabling fatigue, 45.3% reported fatigue rarely to never impacted their life, and 46.4% reported having some fatigue. Persons who reported having less exercise than others with a similar injury level were 2.49 times as likely to have disabling fatigue as persons who reported more exercise. Those with a fair or poor diet were also more likely to have disabling fatigue. Use of prescription medication to treat pain was associated with disabling fatigue, as was being CAGE positive. Among nonbehavioral variables, race and injury severity were significantly associated with disabling fatigue. CONCLUSIONS We identified several behavioral predictors of disabling fatigue, including cardiovascular risk factors, prescription medication use, and alcohol use. These factors are important because they are able to be modified and could be potential factors for prevention or intervention.

Abstract
Objective To evaluate the association of demographic, behavioral, and socioeconomic factors with all-cause mortality while controlling for health status among a cohort of participants with severe disability related to spinal cord injury (SCI). Study Design Prospective cohort study. Setting Data were analyzed at a major medical university in the Southeast United States of America. Methods Participants included 1361 adults with traumatic SCI of at least one year duration who were recruited through a large specialty hospital in the Southeast United States of America. Three Cox proportional hazards models were generated relating the predictors to all-cause mortality. Results Age, disability, smoking, and income were significant in the final model. Both current (hazard ratio [HR]=2.03, 95% confidence interval [CI]=1.46–2.82) and former smokers (HR=1.58, CI=1.16–2.16) were at elevated hazard of mortality, as were those with incomes under $10,000 (HR=2.29, CI=1.53–3.44) and between $10,000–$35,000 (HR=1.47, CI=1.03–2.10). Conclusions Even after controlling for health and severity of disability, the coefficients for smoking and income were significant, exceeding that reported previously within the general population. The importance of these factors may be magnified after severe disability, even though life expectancy is already greatly diminished in this population.

Abstract
STUDY DESIGN Cohort study. OBJECTIVES To identify the stability of socio-environmental, behavioral and health predictors of mortality over an 8-year time frame. SETTING Data were analyzed at a large medical university in the Southeast United States of America (USA). METHODS Adults with residual impairment from a spinal cord injury (SCI) who were at least 1-year post-injury at assessment were recruited through a large specialty hospital in the Southeast USA. A total of 1209 participants were included in the final analysis. A piecewise exponential model with two equal time intervals (8 years total) was used to assess the stability of the hazard and the predictors over time. RESULTS The hazard did significantly change over time, where the hazard in the first time interval was significantly lower than the second. There were no interactions between the socio-environmental, behavior or health factors and time, although there was a significant interaction between age at injury (a demographic variable) and time. CONCLUSION These results suggest there is stability in the association between the predictors and mortality, even over an 8-year time period. Results reinforce the use of historic variables for prediction of mortality in persons with SCI.

Abstract
OBJECTIVE To evaluate the association of health status, secondary health conditions, hospitalizations, and risk of mortality and life expectancy (LE) after spinal cord injury (SCI). DESIGN Prospective cohort study. SETTING Preliminary data were collected from a specialty hospital in the Southeastern United States, with mortality follow-up and data analysis conducted at a medical university. PARTICIPANTS Adults with traumatic SCI (N=1361), all at least 1-year postinjury at the time of assessment, were enrolled in the study. There were 325 deaths. After elimination of those with missing data on key variables, there were 267 deaths and 12,032 person-years. INTERVENTIONS None. MAIN OUTCOME MEASURES The mortality status was determined by routine follow-up using the National Death Index through December 31, 2008. A logistic regression model was developed to estimate the probability of dying in any given year using person-years. RESULTS A history of chronic pressure ulcers, amputations, a depressive disorder, symptoms of infections, and being hospitalized within the past year were all predictive of mortality. LE estimates were generated using the example of a man with noncervical, nonambulatory SCI. Using 3 age examples (20, 40, 60y), the greatest estimated lost LE was associated with chronic pressure ulcers (50.3%), followed by amputations (35.4%), 1 or more recent hospitalizations (18.5%), and the diagnosis of probable major depression (18%). Symptoms of infections were associated with a 6.7% reduction in LE for a 1 SD increase in infectious symptoms. CONCLUSIONS Several secondary health conditions represent risk factors for mortality and diminish LE after SCI. The presence of 1 or more of these factors should be taken as an indicator of the need for intervention.

Abstract
Objective To identify the relationship between spasticity and life satisfaction as measured by 3 multi-item factor scales and a rating of overall quality of life among participants with spinal cord injury (SCI). Study Design Cross-sectional survey; secondary analysis of existing data by linear regression analysis between spasticity and quality of life. Setting Large specialty hospital in the Southeastern United States. Methods Participants included 1,549 adults with traumatic spinal cord injuries, at least 18 years of age and a minimum of 1 year post-injury at survey. Outcome measures included: (1) Home Life Satisfaction, (2) Global Satisfaction, (3) Vocational Satisfaction, (4) Overall Quality of Life and (5) three subscales from the Patient Reported Impact of Spasticity Measure. Results Three aspects of spasticity (Daily Activities, Positive Impact, and spasticity at its worst) all were negatively correlated with Home Life Satisfaction, Global Satisfaction, and Overall Quality of Life. Only the Daily Activities scale and the spasticity at its worst rating had a significant negative correlation with Vocational Satisfaction. Conclusion Spasticity is negatively associated with quality of life after SCI. These negative outcomes need to be considered in an individual’s rehabilitation and treatment methods.

Abstract
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.

Abstract
PURPOSE Among veterans with traumatic spinal cord injury (SCI) or disease aetiologies, examine the association between diagnosed mental illness (MI) and substance use disorders (SUD) on mortality after controlling for demographic and socioeconomic factors, SCI severity, injury duration and chronic physical illnesses. METHOD Longitudinal analysis of Veteran Health Administration(VHA) administrative data and Medicare claims for FY 1999-2004 matched with Spinal Cord Dysfunction-Registry (SCD-R) of VHA clinic users (N = 8334) with SCI. SCI was identified through SCD-R; individual MIs (anxiety, bipolar, depressive disorders, psychoses, post-traumatic disorder and schizophrenia) and SUDs (tobacco, alcohol and/or drug) were identified through ICD-9-CM codes. Cox-proportional hazards regressions were used to examine association between MI and SUD and time to death in years. RESULTS Among veterans with SCI, 17% died by the end of FY 2004. Veterans with psychosis (35%), depression (22%) and alcohol and/or drug use (20%) had significantly higher rates of mortality compared to those without these diagnoses. After adjusting for other independent variables in the study, hazards ratios for psychosis was 1.47 (95%CI = 1.24, 1.75), for alcohol and/or drug use was 1.30 (95% CI = 1.11, 1.53). CONCLUSIONS Some types of MI and SUD were associated with excess mortality among veterans with SCI. Care for MI and SUD needs to be routinely integrated into SCI management. Future research is needed to determine whether depression and SUD treatment provides opportunity to improve survival.

Abstract
PURPOSE This study aimed to provide a broad overview of the health of people with spinal cord injury (SCI) in Singapore, so as to highlight areas of potential need. These areas could then guide future research and rehabilitation programme development. METHODS Demographic data, injury information and information about SCI-related secondary impairments, chronic conditions and their associated risk factors, medical and hospital utilisation, participation (Craig Handicap Assessment and Reporting Technique) and life satisfaction (Satisfaction with Life Scale) were collected via interviews from people living with traumatic SCI. RESULTS On average, participants (50 men and 5 women) were aged 48.3 ± 16.54 years and had had their SCIs for 5 years. -75% with tetraplegia. The most prevalent SCI-related secondary impairments were pain, spasms, bladder problems, bowel problems and oedema. Chronic conditions and their associated risk factors were prevalent. Participation and life satisfaction scores were lower than those reported for similar populations cross-culturally. CONCLUSION The study revealed several health areas that may be affecting the overall health of people with SCI in Singapore. By focusing on community reintegration and health promotion, physiotherapists and other rehabilitation professionals may augment health outcomes and improve the quality of life of this population in Singapore.

[PMID: 21044720 PMCID: PMC3181076 DOI: 10.1016/j.apmr.2010.07.219] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2010] [Revised: 07/02/2010] [Accepted: 07/24/2010] [Indexed: 10/18/2022]
Abstract
OBJECTIVES To identify (1) the annual incidence of subsequent injury and injury-related hospitalizations in persons with preexisting spinal cord injury (SCI) and (2) risk and protective behaviors associated with differential risk for injury. DESIGN Longitudinal mailed survey. Participants were enrolled in 1997 to 1998, with a follow-up conducted 10 years later. SETTING Data were collected from participants identified from a specialty hospital and were analyzed at a medical university in the Southeastern United States. PARTICIPANTS Participants (N=1386) during the baseline enrollment, 821 of whom also participated in the 10-year follow-up. Inclusion criteria were (1) traumatic SCI with residual impairment, (2) nonsurgical onset, (3) aged 18 years or older, and (4) a minimum of 12 months post-SCI. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Number of injuries severe enough to require treatment in a clinic, emergency department, or hospital in the 12 months before the survey and number of injury-related hospitalizations. Predictor variables included selected items from the Behavioral Risk Factor Surveillance System, the Zuckerman-Kuhlman Personality Questionnaire, and prescription medication use. RESULTS More than 23% of participants reported at least 1 injury within the past year, an increase from that reported 10 years earlier by the same participants (19%), and 7% reported at least 1 injury-related hospitalization. Those who reported a subsequent injury during the preliminary baseline data collection were about twice as likely to report at least 1 injury 10 years later. Binge drinking, psychotropic prescription medication use, and several personality characteristics also were related to injuries and/or injury-related hospitalization. CONCLUSIONS Risk for injury continues to be a significant concern in the years and decades after SCI onset. Behavioral and personality factors hold the key to prevention.

Abstract
PURPOSE: To assess the relationship of psychological, environmental, and behavioral factors with pressure ulcers (PUs) in persons with spinal cord injury (SCI). METHODS: A total of 1,549 participants from a large rehabilitation hospital in the southeast United States answered questions regarding outcomes after SCI. Variables from each set of factors were entered sequentially into the model: (1) psychological and environmental, and (2) behavioral. RESULTS: Forty-eight percent of participants reported having a PU in the past year. After entering behavioral variables into the model, all environmental and psychological variables became nonsignificant. Odds of having a PU increased 28% with each psychotropic medication taken weekly. Persons who smoked one or more packs of cigarettes daily had 2.82 times the odds of having a PU than persons who did not smoke. Increased hours out of bed were protective against PUs. CONCLUSION: This study demonstrated the importance of health behaviors in the occurrence of PUs after SCI. These health behaviors provide important targets for intervention for health care providers.
