Feasibility of Brief, Hypnotic Enhanced Cognitive Therapy for SCI-related Pain During Inpatient Rehabilitation

OBJECTIVES

(1) Adapt evidence-based hypnosis-enhanced cognitive therapy (HYP-CT) for inpatient rehabilitation setting; and (2) determine feasibility of a clinical trial evaluating the effectiveness of HYP-CT intervention for pain after spinal cord injury (SCI).

STUDY DESIGN

Pilot non-randomized controlled trial.

SETTING

Inpatient rehabilitation unit.

PARTICIPANTS

English-speaking patients admitted to inpatient rehabilitation after SCI reporting current pain of at least 3 on a 0-10 scale. Persons with severe psychiatric illness, recent suicide attempt or elevated risk, or significant cognitive impairment were excluded. Consecutive sample of 53 patients with SCI-related pain enrolled, representing 82% of eligible patients.

INTERVENTION

Up to 4 sessions of HYP-CT Intervention, each 30-60 minutes long.

METHODS

Participants were assessed at baseline and given the choice to receive HYP-CT or Usual Care.

MAIN OUTCOME MEASURES

Participant enrollment and participation and acceptability of intervention. Exploratory analyses examined the effect of intervention on pain and cognitive appraisals of pain.

RESULTS

In the HYP-CT group, 71% completed at least 3 treatment sessions and reported treatment benefit and satisfaction with the treatment; no adverse events were reported. Exploratory analyses of effectiveness found pre-post treatment pain reductions after HYP-CT with large effect (P<.001; β=-1.64). While the study was not powered to detect significant between-group differences at discharge, effect sizes revealed decreases in average pain (Cohen's d=-0.13), pain interference (d=-0.10), and pain catastrophizing (d=-0.20) in the HYP-CT group relative to control and increases in self-efficacy (d=0.27) and pain acceptance (d=0.15).

CONCLUSIONS

It is feasible to provide HYP-CT to inpatients with SCI, and HYP-CT results in substantial reductions in SCI pain. The study is the first to show a psychological-based nonpharmacologic intervention that may reduce SCI pain during inpatient rehabilitation. A definitive efficacy trial is warranted.

Utilization of rehabilitation services in violent versus nonviolent traumatic spinal cord injury

BACKGROUND

Violence is the third leading cause of spinal cord injury (SCI) in the United States, and people with violence-related SCI have worse long-term outcomes compared to other traumatic SCI etiologies. Little is known, however, about the underlying reasons for these differences. Access to and utilization of rehabilitation services may differ in this population, but their outpatient care has not been previously investigated.

OBJECTIVE

To evaluate differences in utilization patterns of outpatient rehabilitation services between people with violence-related SCI and other traumatic SCI etiologies.

DESIGN

Retrospective cohort study.

SETTING

Academic tertiary care hospital system.

PATIENTS

A total of 41 patients with violence-related SCI residing in King County at the time of injury who completed inpatient rehabilitation (IPR) in our institution were identified from the hospital trauma registry and matched with 41 control patients with nonviolent traumatic SCI.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE(S)

The number of appointments attended, canceled, and missed during the first year after discharge from IPR were obtained by chart review for physical medicine & rehabilitation (PM&R) physicians and therapy services.

RESULTS

People with violence-related SCI had decreased follow-up with outpatient rehabilitation services after IPR discharge compared to non-violent traumatic SCI, including PM&R (2.50 ± 2.44 vs. 3.76 ± 2.21 visits, β = -1.28, p = .017), physical therapy (8.91 ± 11.02 vs. 17.57 ± 15.26, β = -9.79, p = .009), occupational therapy (4.28 ± 7.90 vs. 10.04 ± 14.42, β = -6.18, p = .033), and recreational therapy (0.293 ± 0.955 vs. 1.37 ± 2.86, β = -1.07, p = .035). The rate of missed appointments was also higher among people with violence-related SCI compared to controls for PM&R (25.2% ± 28.5% vs. 9.9% ± 16.5%, β = 14.6%, p = .014) and physical therapy (26.0% ± 32.0% vs 4.2% ± 13.2%, β = 22.1%, p = .009).

CONCLUSIONS

Individuals with violence-related SCI had fewer follow-up appointments with PM&R physicians and other allied health professionals and were more likely to miss scheduled appointments compared to other traumatic SCI etiologies. Decreased outpatient follow-up may affect long-term outcomes for people with violence-related SCI.

Birth Outcomes and Rehospitalizations Among Pregnant Women With Rheumatoid Arthritis and Systemic Lupus Erythematosus and Their Offspring

OBJECTIVE

To compare obstetric/birth outcomes and rehospitalization among women with and without rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE) and their infants.

METHODS

This population-based retrospective cohort study identified women with RA (n = 1,223) and SLE (n = 1,354) and unexposed women with singleton births 1987-2014 in Washington State in linked vital hospital discharge records. Outcomes, including cause-specific hospitalizations <2 years postpartum, were compared by estimating adjusted relative risks (RRs) and cause-specific rehospitalization hazard ratios (HRs) with 95% confidence intervals (95% CIs).

RESULTS

We observed increased risks of several adverse outcomes; RRs were often greatest for SLE. Women with RA/SLE more often required rehospitalization, most notably at <6 months postpartum (RA: 4% versus 2%; RR 2.22 [95% CI 1.62-3.04]; SLE: 6% versus 2%; RR 2.78 [95% CI 2.15-3.59]). Maternal postpartum rehospitalization was greatest for musculoskeletal conditions (RA: HR 19.1 [95% CI 13.6-26.8]; SLE: HR 29.8 [95% CI 22.1-40.1]). Infants of women with SLE more often had malformations (9% versus 6%; RR 1.46 [95% CI 1.21-1.75]), and increased mortality at <2 years (RR 2.11 [95% CI 1.21-3.67]). Infants of women with SLE also experienced more frequent rehospitalizations in their first year of life.

CONCLUSION

Women with RA or SLE and their infants experienced adverse outcomes, particularly infants of women with SLE. Maternal/infant rehospitalization was more common; most marked in the early months postpartum. Close follow-up during these time periods is crucial to minimize adverse outcomes.

Positive predictive value of a sepsis-screening protocol for patients with tetraplegia

OBJECTIVE

To determine the positive predictive value (PPV) of a sepsis-screening protocol in patients with cervical spinal cord injury (SCI).

DESIGN/METHOD

Retrospective review of all patients with cervical SCI who screened positive for two or more systemic inflammatory response syndrome (SIRS) criteria while hospitalized in acute care or inpatient rehabilitation units over a 3.5-year period. Sepsis was defined by the occurrence of (1) any culture order followed by an intravenous (IV) antibiotic within 72 hours or (2) an IV antimicrobial followed by a culture order within 24 hours.

RESULTS

A total of 134 patients screened positive for two or more SIRS criteria. Of these, 36 patients (26.9%) were diagnosed with sepsis. Factors associated with a true-positive SIRS screen on multivariable analysis included American Spinal Injury Association Impairment Scale (AIS) grade A-C (vs. D; p < .001). The PPV of the screen was 38% in patients with AIS A-C and 9% in patients with AIS D. Altered mental status (AMS) was strongly associated with a diagnosis of sepsis; 16 of 18 (88.9%) of those with AMS had sepsis (p < .001). Age, sex, and neurologic level of injury were not associated with true-positive screening. For patients with new SCI, the first true-positive screen occurred a median of 31 days post-injury. The most common SIRS criteria combinations in patients with true-positive screens were elevated heart rate and either abnormal white blood cell count (43% of true positives) or abnormal temperature (26% of true positives). Abnormally low body temperature (<36°C) contributed to false-positive screening for 10 of 38 (26%) AIS D patients who screened positive.

CONCLUSION

Sepsis screening using SIRS criteria in hospitalized patients with tetraplegia has a PPV of 26.9%; it is significantly higher in patients with AIS A-C versus D injuries. AMS, when combined with a positive SIRS screening, is strongly associated with sepsis.

A Case Study of Hypnosis Enhanced Cognitive Therapy for Pain in a Ventilator Dependent Patient during Inpatient Rehabilitation for Spinal Cord Injury

Early, acute pain following spinal cord injury (SCI) is common, can negatively impact SCI rehabilitation, and is frequently not responsive to biomedical treatment. Nonpharmacological interventions show promise in reducing pain for individuals with SCI. However, most psychological interventions rely heavily on verbal interaction between the individual being treated and the clinician, making them inaccessible for individuals with impaired verbal output due to mechanical ventilation. This case study aims to describe the adaptation and implementation of hypnotic cognitive therapy (HYP-CT) intervention for early SCI pain in the context of mechanical ventilation dependence and weaning. The participant was a 54-year-old male with C2 AIS A SCI requiring mechanical ventilation. Four sessions of HYP-CT were provided during inpatient rehabilitation with assessment prior to intervention, after the intervention sessions, and prior to discharge. The participant reported immediate reductions in pain intensity following each intervention session. Overall, he reported increases in self-efficacy and pain acceptance. He did not report any negative treatment effects and thought the intervention provided support during mechanical ventilation weaning. During treatment, he discontinued opioid pain medications and reported actively using intervention strategies. Our results support the potential for early, hypnotic cognitive therapy for individuals with SCI experiencing pain or distress while dependent on mechanical ventilation.

Pregnancy outcomes among visually impaired women in Washington State, 1987-2014

BACKGROUND

Women with visual impairment may have reduced ability to access standard care resources, however, information on their pregnancy and neonatal outcomes is limited.

OBJECTIVE

To assess risk of adverse pregnancy and neonatal outcomes among visually impaired women in Washington State from 1987 to 2014.

METHODS

We conducted a retrospective cohort study using linked Washington State birth/fetal death hospital discharge records to compare outcomes among women with and without visual impairment noted at their delivery hospitalization. Pregnancy conditions and outcomes evaluated included gestational diabetes, pre-eclampsia, labor induction and cesarean delivery. Neonatal outcomes included preterm delivery and birth weight <2500 g. We assessed length of maternal and infant delivery hospitalization. We performed Poisson regression to estimate relative risks (RR) and 95% confidence intervals (CIs) for each outcome, adjusting for year of delivery, maternal age, and parity.

RESULTS

Most adverse pregnancy and neonatal outcomes were similar for visually impaired (N = 232) and comparison women (N = 2362). However, visually impaired women had increased risks of severe pre-eclampsia (RR 3.77, 95% CI 1.69-8.43), labor induction (RR 1.33, 95% CI 1.10-1.61) and preterm delivery (RR 1.60, 95% CI 1.06-2.42). They were also more likely to have delivery hospitalizations of 3 or more days following a vaginal (RR 1.86, 95% CI 1.41-2.47). Among cesarean deliveries, infants of visually impaired women had increased risk (RR 1.24, 95% CI 1.02-1.51) of hospitalization for 3 or more days postpartum.

CONCLUSION

Our findings may be useful for obstetric providers in counseling their visually impaired patients.

A tele-health intervention to increase physical fitness in people with spinal cord injury and cardiometabolic disease or risk factors: a pilot randomized controlled trial

STUDY DESIGN

Clinical trial.

OBJECTIVES

We used a single-blind parallel-group design to test the feasibility and preliminary efficacy of a telehealth-based physical activity counseling intervention to increase physical fitness in people with SCI.

SETTING

Seattle, Washington, United States.

METHODS

We recruited under-active, manual wheelchair-using adults at least 1-year post-SCI who had at least two cardiometabolic risk factors/diseases. Participants underwent baseline tests of peak cardiorespiratory fitness; lipids, glucose and insulin; muscle and fat mass; self-reported physical activity, depression, pain and other factors. Participants were assigned 1:1 to treatment vs. usual care (UC) control conditions via concealed computerized randomization. Treatment was delivered via telephone and adapted from the 16-session Diabetes Prevention Program. All baseline tests were repeated at 6 months. Prespecified feasibility goals were to recruit at least nine participants/quarter and retain 85% with complete fitness testing at 6 months. Prespecified efficacy goals were to demonstrate at least a medium treatment effect size (0.50) on fitness, self-reported physical activity, and other outcomes.

RESULTS

Seven participants were randomized to treatment, 8 to UC over 15 months. Maximum recruitment was only 5.4 participants/quarter. Thirteen (87%) of participants were retained. The effects of treatment on fitness and most cardiometabolic risk factors did not meet expectations, whereas the effects on self-reported physical activity, depression, and pain did meet expectations.

CONCLUSIONS

The study did not meet key efficacy and feasibility objectives, yet there were some promising effects on self-report measures and lessons to be learned for designing future trials.

Pregnancy Outcomes in Women with Spinal Cord Injuries: A Population-Based Study

BACKGROUND

Pregnant women with congenital or acquired spinal cord injury face challenges due to compromised neurologic function and mobility, factors that may also affect fetal/infant health. Few studies have examined pregnancy course and longer-term outcomes in this population.

OBJECTIVE

To assess pregnancy outcomes among women with spinal cord injury, paralysis, or spina bifida using population-based data.

DESIGN

Retrospective cohort study.

SETTING

Washington state linked birth-hospital discharge records.

PARTICIPANTS

All women (N = 529) with spinal cord injury, paralysis, or spina bifida with singleton live birth deliveries 1987-2012, and a comparison group of women without disabilities (N = 5282).

METHODS

Diagnosis codes were screened to identify cases and a 10:1 random sample of comparison women. Relative risks (RRs) and 95% confidence intervals (CIs) were calculated overall and separately for each condition using multivariable regression. Subsequent hospitalizations or death were identified via linkage to hospital discharge/death records for 2 years after delivery.

MAIN OUTCOME MEASUREMENTS

Pregnancy course (weight gain, gestational diabetes, preeclampsia, infection, venous thromboembolism), delivery/labor characteristics, infant characteristics (birthweight/size, gestational age), and longer-term outcomes (occurrence/reasons for maternal/infant rehospitalization, mortality).

RESULTS

Women with these spinal conditions had increased adjusted risks of prenatal urinary tract infection/pyelonephritis (RR 26.43, 95% CI 13.97-49.99), venous thromboembolism (RR 9.16, 95% CI 2.17-38.60), preterm rupture of membranes (RR 2.15, 95% CI 1.18-3.90), and cesarean delivery (RR 1.88, 95% CI 1.70-2.09). They had longer hospitalizations and increased rehospitalization (RR 1.54, 95% CI 1.28-1.87), including for postpartum depression (RR 8.15, 4.29-15.48) or injury (RR 13.05, 95% CI 6.60-25.81). Their infants were more often small for gestational age (RR 1.65, 95% CI 1.33-2.06), but had no increased risk of rehospitalization or death.

CONCLUSIONS

We observed no increased long-term morbidity among infants of women with these conditions. Possible increased maternal morbidities during the first postpartum years indicate areas for intervention.

Benefits of an exercise wellness program after spinal cord injury

OBJECTIVE

To describe the initial benefits of a structured group exercise program on exercise frequency and intensity, perceived health, pain, mood, and television watching habits.

DESIGN

Pre-test/post-test.

PARTICIPANTS/METHODS

Eighty-nine persons with SCI participated voluntarily in a no-cost, twice weekly physical therapy group exercise class over 3 months. Forty-five persons completed pre- and post-participation interviews on exercise frequency and intensity, perceived health, pain, mood, sleep, and television watching habits.

RESULTS

Mean participant age of the respondents was 43.82 years. 49% had AIS C or D injuries, 24% had AIS A,B paraplegia, 9% had AIS A,B C1-C4 and 18% had AIS A,B C5-C8. 75.6% of participants were male and 84.4% had a traumatic etiology as the cause of their SCI. There was a significant improvement in days of strenuous and moderate exercise as well as health state. There was an average decrease in pain scores, depression scores, number of hours spent watching television, and days/week of mild exercise.

CONCLUSION

Participation in structured, small group exercise as a component of a wellness program after SCI shows promise for improving regular exercise participation and health state, but benefits may also occur across other areas of health and function including mood, pain, and hours spent watching television. Further follow-up is needed to determine whether improvements can be maintained after program completion and across all neurological levels.

Effect of Continuous Positive Airway Pressure on Stroke Rehabilitation: A Pilot Randomized Sham-Controlled Trial

STUDY OBJECTIVES

Obstructive sleep apnea (OSA) predicts poor functional outcome after stroke and increases the risk for recurrent stroke. Less is known about continuous positive airway pressure (CPAP) treatment on stroke recovery.

METHODS

In a pilot randomized, double-blind, sham-controlled trial, adult stroke rehabilitation patients were assigned to auto-titrating or sham CPAP without diagnostic testing for OSA. Change in Functional Independence Measure (FIM), a measure of disability, was assessed between rehabilitation admission and discharge.

RESULTS

Over 18 months, 40 patients were enrolled and 10 withdrew from the study: 7 from active and 3 from sham CPAP (p > 0.10). For the remaining 30 patients, median duration of CPAP use was 14 days. Average CPAP use was 3.7 h/night, with at least 4 h nightly use among 15 patients. Adherence was not influenced by treatment assignment or stroke severity. In intention-to-treat analyses (n = 40), the median change in FIM favored active CPAP over sham but did not reach statistical significance (34 versus 26, p = 0.25), except for the cognitive component (6 versus 2.5, p = 0.04). The on-treatment analyses (n = 30) yielded similar results (total FIM: 32 versus 26, p = 0.11; cognitive FIM: 6 versus 2, p = 0.06).

CONCLUSIONS

A sham-controlled CPAP trial among stroke rehabilitation patients was feasible in terms of recruitment, treatment without diagnostic testing and adequate blinding-though was limited by study retention and CPAP adherence. Despite these limitations, a trend towards a benefit of CPAP on recovery was evident. Tolerance and adherence must be improved before the full benefits of CPAP on recovery can be assessed in larger trials.

Beyond broken spines-what the radiologist needs to know about late complications of spinal cord injury

OBJECTIVE

To describe expected imaging findings to assist the emergency room radiologist with recognising complications and pathology unique to the spinal cord injury (SCI) patient population to ensure rapid and accurate diagnosis.

METHODS

Pictorial review.

RESULTS

We review several imaging findings common to persons with chronic SCI, emphasising imaging in the emergency setting and on CT.

CONCLUSION

SCI patients present a unique diagnostic challenge, as they may present with symptoms that are difficult to localise because of abnormal sensation and autonomic instability. Imaging plays an important role in the emergent setting, rapidly differentiating the most commonly encountered complications from less common, unanticipated complications. Radiologists need to be attuned to both the expected findings and potential complications, which may be unique to SCI patients, to ensure accurate diagnosis and treatment in the emergency setting.

MAIN MESSAGES

• Medical complications after spinal cord injury are common and associated with significant morbidity. • Radiologists should be aware of complications unique to the SCI population to aid diagnosis. • Due to abnormal sensation, SCI patients often present with symptoms that are difficult to localise. • In the ED, imaging helps to rapidly differentiate common complications from less anticipated ones.

Weight gain following spinal cord injury: a pilot study

STUDY DESIGN

Retrospective chart review.

OBJECTIVE

To define the temporal course of weight gain in persons with new spinal cord injury (SCI), and to identify predictors of weight gain in this population.

SETTING

A United States Department of Veterans Affairs (VA) SCI Unit.

METHODS

A retrospective chart review in a VA SCI Unit was conducted. Participants (n = 85) included all persons with new SCI completing initial rehabilitation at the center between 1998 and 2006. Outcome measures were mean change in body mass index (BMI) between rehabilitation admission and final follow-up, time of greatest BMI change, and distribution of participants by BMI classification. These measures were also examined relative to SCI level, American Spinal Injury Association Impairment Scale (AIS) grade, primary mode of mobility, and age at rehabilitation admission.

RESULTS

Mean BMI increased by 2.3 kg/m2 between rehabilitation admission (mean 45 days post-injury) and final follow-up (mean 5 years post-injury). The distribution of participants shifted from lower BMI classifications at rehabilitation admission to higher BMI classifications at final follow-up. For participants transitioning from normal to overweight or obese, the greatest increase occurred during the first year after acute rehabilitation. Neurological level, impairment category, primary mode of mobility, and age at rehabilitation admission did not significantly predict BMI change. BMI at rehabilitation admission correlated significantly with BMI at final follow-up (P < 0.0005).

CONCLUSIONS

These findings confirm a significant increase in BMI after new SCI and suggest that persons with new SCI are at greatest weight gain risk during the first year following acute rehabilitation.

Intractable pruritus after traumatic spinal cord injury

BACKGROUND

This report describes a young woman with incomplete traumatic cervical spinal cord injury and intractable pruritus involving her dorsal forearm.

METHOD

Case report.

FINDINGS

Anatomic distribution of the pruritus corresponded to the dermatomal distribution of her level of spinal cord injury and vertebral fusion. Symptoms were attributed to the spinal cord injury and possible cervical root injury. Pruritus was refractory to all treatments, including topical lidocaine, gabapentin, transcutaneous electrical nerve stimulation, intravenous Bier block, stellate ganglion block, and acupuncture.

CONCLUSIONS

Further understanding of neuropathic pruritus is needed. Diagnostic workup of intractable pruritus should include advanced imaging to detect ongoing nerve root compression. If diagnostic studies suggest radiculopathy, epidural steroid injection should be considered. Because the autonomic nervous system may be involved in complex chronic pain or pruritic syndromes, sympatholysis via such techniques as stellate ganglion block might be effective.

Observation of muon neutrino disappearance with the MINOS detectors in the NuMI neutrino beam

This Letter reports results from the MINOS experiment based on its initial exposure to neutrinos from the Fermilab NuMI beam. The rates and energy spectra of charged current nu(mu) interactions are compared in two detectors located along the beam axis at distances of 1 and 735 km. With 1.27 x 10(20) 120 GeV protons incident on the NuMI target, 215 events with energies below 30 GeV are observed at the Far Detector, compared to an expectation of 336+/-14 events. The data are consistent with nu(mu) disappearance via oscillations with |Delta(m)2/32|=2.74 +0.44/-0.26 x10(-3)eV(2) and sin(2)(2theta(23))>0.87 (68% C.L.).
