Characteristics and Survival of Patients with Acute Traumatic Spinal Cord Injury Above T6 with Prolonged Intensive Care Unit Stays

Early rehabilitation after spinal cord injury: a scoping review protocol

OBJECTIVE

The objective of this scoping review is to identify the timings and types of early rehabilitation after spinal cord injury (SCI) that are documented in the literature, as well as identify possible research gaps in this field.

INTRODUCTION

Preclinical and clinical studies support the idea that early rehabilitation may be beneficial for patients with acute SCI. However, the timings and types of rehabilitation that should and could be used in the acute stage are still unclear. The first step towards such knowledge is to extensively review what is documented in the literature.

INCLUSION CRITERIA

This review will consider all papers focusing on early rehabilitation after SCI in adult humans or animals (<3 months' post-SCI for humans and other primates and <3 weeks' post-SCI for other animals). Interventions in the included papers must aim at sensorimotor or functional improvement and take place in a hospital or a rehabilitation center if they target human subjects. This review will include published and unpublished experimental and observational studies, research protocols, conference abstracts, systematic reviews, and guidelines.

METHODS

MEDLINE (PubMed), Scopus, Embase, PEDro, Web of Science Core Collection, CINAHL (EBSCOhost), Cochrane Database of Systematic Reviews, Cochrane CENTRAL, PROSPERO, ClinicalTrials.gov, and gray literature sources will be searched for eligible articles. No language or date limits will be applied. Two independent reviewers will perform study selection and data extraction, and the results will be presented according to the SCI type and severity.

Guidelines for neuroprognostication in adults with traumatic spinal cord injury

BACKGROUND

Traumatic spinal cord injury (tSCI) impacts patients and their families acutely and often for the long term. The ability of clinicians to share prognostic information about mortality and functional outcomes allows patients and their surrogates to engage in decision-making and plan for the future. These guidelines provide recommendations on the reliability of acute-phase clinical predictors to inform neuroprognostication and guide clinicians in counseling adult patients with tSCI or their surrogates.

METHODS

A narrative systematic review was completed using Grading of Recommendations Assessment, Development, and Evaluation methodology. Candidate predictors, including clinical variables and prediction models, were selected based on clinical relevance and presence of an appropriate body of evidence. The Population/Intervention/Comparator/Outcome/Timing/Setting question was framed as "When counseling patients or surrogates of critically ill patients with traumatic spinal cord injury, should < predictor, with time of assessment if appropriate > be considered a reliable predictor of < outcome, with time frame of assessment >?" Additional full-text screening criteria were used to exclude small and lower quality studies. Following construction of an evidence profile and summary of findings, recommendations were based on four Grading of Recommendations Assessment, Development, and Evaluation criteria: quality of evidence, balance of desirable and undesirable consequences, values and preferences, and resource use. Good practice recommendations addressed essential principles of neuroprognostication that could not be framed in the Population/Intervention/Comparator/Outcome/Timing/Setting format. Throughout the guideline development process, an individual living with tSCI provided perspective on patient-centered priorities.

RESULTS

Six candidate clinical variables and one prediction model were selected. Out of 11,132 articles screened, 369 met inclusion criteria for full-text review and 35 articles met eligibility criteria to guide recommendations. We recommend pathologic findings on magnetic resonance imaging, neurological level of injury, and severity of injury as moderately reliable predictors of American Spinal Cord Injury Impairment Scale improvement and the Dutch Clinical Prediction Rule as a moderately reliable prediction model of independent ambulation at 1 year after injury. No other reliable or moderately reliable predictors of mortality or functional outcome were identified. Good practice recommendations include considering the complete clinical condition as opposed to a single variable and communicating the challenges of likely functional deficits as well as potential for improvement and for long-term quality of life with SCI-related deficits to patients and surrogates.

CONCLUSIONS

These guidelines provide recommendations about the reliability of acute-phase predictors of mortality, functional outcome, American Spinal Injury Association Impairment Scale grade conversion, and recovery of independent ambulation for consideration when counseling patients with tSCI or their surrogates and suggest broad principles of neuroprognostication in this context.

Hospital Course and Complications of Subaxial Cervical Trauma Patients With Tetraplegia or Paraplegia: A Case Series and Literature Review

STUDY DESIGN

A single-institution, retrospective cohort study.

OBJECTIVE

The objective was to present demographic characteristics, mechanism of injuries, lengths of stay, intensive care unit (ICU) days, discharge locations, and causes of 90-day readmission for patients with subaxial spinal cord injuries resulting in paraplegia or tetraplegia.

SUMMARY OF BACKGROUND DATA

Spinal cord injuries resulting in paraplegia or tetraplegia are rare injuries with debilitating outcomes. Numerous advances have occurred in caring for these patients, but patients still experience multiple complications. The severity of these injuries and numerous complications result in prolonged hospital stays and the need for extensive rehabilitation.

METHODS

Twelve patients with subaxial spinal cord injury resulting in paraplegia or tetraplegia from a level 1 adult trauma center were reviewed. The primary outcomes included hospital length of stay, ICU days, intrahospital complications, 90-day readmission rates, and discharge location. We reviewed the literature for these outcomes in spinal cord injuries.

RESULTS

For patients with subaxial spinal cord injuries resulting in paraplegia and tetraplegia, the average age was 36.0 years, and most were male [91.7% (11/12)]. The most common mechanism of injury was gunshot wounds[41.7% (5/12)]. Patients spent an average of 46.3 days in the hospital and 30.7 days in the ICU. Respiratory complications were the most common (9 patients). Fifty percent of patients (6/12) were discharged to the inpatient spinal cord rehab center, and 16.7% (2/12) expired while in the hospital. Two patients (20.0%) were readmitted within 90 days of discharge.

CONCLUSIONS

Most patients with subaxial spinal cord injuries resulting in paraplegia or tetraplegia were young males with high-energy traumas. Many patients had intrahospital complications, and most were discharged to the hospital spinal rehab center. These findings likely stem from the severity of paraplegia and tetraplegia injuries and the need for rehabilitation.

Predictors of Intensive Care Unit Stay in Patients with Acute Traumatic Spinal Cord Injury Above T6

OBJECTIVE

The objective of this study was to identify factors associated with the intensive care unit (ICU) length of stay (LOS) of patients with an acute traumatic spinal cord injury above T6.

METHODS

We performed a retrospective, observational study of patients admitted to an ICU between 1998 and 2017 (n = 241). The LOS was calculated using a cumulative incidence function, with events of death being considered a competing event. Factors associated with the LOS were analyzed using both a cause-specific Cox proportional hazards regression model and a competing risk model. A multistate approach was also used to analyze the impact of nosocomial infections on the LOS.

RESULTS

A total of 211 patients (87.5%) were discharged alive from the ICU (median LOS = 23 days), and 30 (12.4%) died (median LOS = 11 days). In the multivariate analysis after adjusting for variables collected 4 days after the ICU admission, a higher American Spinal Injury Association motor score (subdistribution hazards ratio [sHR] = 1.01), neurological level C5-C8 (HR = 0,64), and lower Sequential Organ Failure Assessment score (sHR = 0.82) and fluid balance (sHR = 0.95) on day 4 were linked to a lower LOS in this unit. In the multivariate analysis, the onset of an infection was significantly associated with a longer LOS when adjusting for variables collected both at ICU admission (adjusted sHR = 0.62; 95% confidence interval = 0.50-0.77) and on day 4 (adjusted hazards ratio = 0.65; 95% confidence interval = 0.52-0.80).

CONCLUSIONS

After adjusting the data for conventional variables, we identified a lower American Spinal Injury Association motor score, injury level C5-C8, a higher Sequential Organ Failure Assessment score on day 4, a more positive fluid balance on day 4, and the onset of an infection as factors independently associated with a longer ICU LOS.
