Background: Healthcare inequities for patients with traumatic brain injury (TBI) represent a major priority area for trauma quality improvement. We hypothesized a relationship between health insurance status and timing of withdrawal of life sustaining treatment (WLST) for adults with severe TBI. Methods: This multicenter retrospective observational cohort study utilized data collected between 2017 and 2020. We identified adult (age ≥ 16) patients with isolated severe TBI admitted participating Trauma Quality Improvement Program centers. We determined the relationship between insurance status (public, private, and uninsured) and the timing of WLST using a competing risk survival analysis framework adjusting for baseline, clinical, injury and trauma center characteristics. Multivariable cause-specific Cox regressions were used to compute adjusted hazard ratios (HR) reflecting timing of WLST, accounting for mortality events. We also quantified the between-center residual variability in WLST using the median odds ratio (MOR) and measured insurance status association with access to rehabilitation at discharge. Results: We identified 42,111 adults with isolated severe TBI treated across 509 trauma centers across North America. There were 10,771 (25.6%) WLST events in the cohort and a higher unadjusted incidence of WLST events was evident in public insurance patients compared to private or uninsured groups. After adjustment, WLST occurred earlier for publicly insured (HR 1.07, 95% CI 1.02–1.12) and uninsured patients (HR 1.29, 95% CI 1.18–1.41) compared to privately insured patients. Access to rehabilitation was lower for both publicly insured and uninsured patients compared to patients with private insurance. Accounting for case-mix, the MOR was 1.49 (95% CI 1.43–1.55), reflecting significant residual between-center variation in WLST decision-making. Conclusions: Our findings highlight the presence of disparate WLST practices independently associated with health insurance status. Additionally, these results emphasize between-center variability in WLST, persisting despite adjustments for measurable patient and trauma center characteristics. [ABSTRACT FROM AUTHOR]

This study aims to estimate real-world clinical practice trends in time to surgery following thoracolumbar spinal cord injury (SCI) in trauma centers across North America over the last decade (2010-2020). A multi-center retrospective observational study was conducted using Trauma Quality Improvement Program data from 2010 to 2020. All surgically treated patients with thoracic and lumbar SCI were included. Descriptive plots and a multivariable Poisson regression model with time to spine surgery as the primary outcome were constructed. This study included 4350 adult patients with complete SCI surgically treated across 449 trauma centers. Within this group, 3978 (91.4%) patients were diagnosed with thoracic SCI and 372 (8.6%) patients were diagnosed with lumbar SCI. The overall mean time to surgery was 31.6 h (±34.1). Early surgery (≤24 h) was performed in 2599 patients (59.7%). An estimated annual reduction of 1.6 h in time to surgery was demonstrated over the study period, starting initially at a mean of 47.6 h (±40.6) in 2010, and reaching a mean of 25.3 h (±30) in 2020. Multivariable Poisson regression adjusting for patient, injury, and institution confounders, demonstrated a significant decrease in time to surgery by 5% per year over the study period (incidence rate ratios [IRR] = 0.95, 95% confidence interval [CI]: 0.93-0.96). Moreover, in a secondary analysis including 3270 patients with incomplete thoracolumbar SCI, a comparable significant annual reduction in time to surgery was demonstrated (IRR = 0.93, 95% CI: 0.91-0.94). This study provides real-world data on practice pattern trends with respect to time to spine surgery following traumatic thoracolumbar SCI. Over the years from 2010 to 2020, we found a significant reduction in time to surgery across trauma centers in North America.

This study aims to quantify the change in time to surgery for treatment of complete traumatic cervical spinal cord injury (SCI) patients in American College of Surgeons accredited trauma centers across North America over the last decade (2010-2020). This multi-center retrospective observational cohort study used data from the Trauma Quality Improvement Program from 2010 to 2020. All surgically treated patients with complete traumatic cervical SCI were included. Primary outcome was time to spine surgery from treating hospital arrival in hours. Both descriptive statistics and a multi-variable Poisson regression model clustering standard of errors by each included trauma center were used to evaluate and quantify the annual change in time to surgical intervention. The study included 6855 complete traumatic cervical SCI patients managed across 484 trauma centers in North America. Median time to spine surgery was 14.6 h. A total of 4618 patients (67.3%) underwent surgical intervention within 24 h from hospital arrival. From 2010 to 2020, median time to surgery decreased by an average 0.6 h (±0.15) per year. A multi-variable adjusted model for time to surgery demonstrated a significant downward annual reduction of 5% in time to surgery between the years 2010 and 2020 (Incidence rate ratio = 0.95; 95% Confidence Interval: 0.93-0.96). This study provides compelling real-world based quantification of the change in time to surgical intervention following traumatic cervical SCI. A significant decreasing annual trend pertaining to surgical timing across trauma centers in North America over the past decade was demonstrated.
