Baylor Scott & White Medical Center Trauma Study Questions 24-Hour Surgery Window
Surgical intervention within 24 hours of hospital presentation for traumatic spinal injury failed to show an independent association with improved short-term functional outcomes, according to a retrospective observational study. Researchers at Baylor Scott & White Medical Center in Temple, Texas, evaluated 147 patients who underwent surgical fixation between January 1, 2019, and December 31, 2023, finding that patient age and baseline neurological impairment proved more decisive for 30-day recovery than operating within the standard one-day window.
Patient Cohort and Modified Rankin Scale Outcomes at 30 Days
The study analyzed patients treated for traumatic spinal injury to determine functional status 30 days after surgical intervention using the Modified Rankin Scale (mRS). Out of the 147 total patients meeting inclusion criteria, 69 individuals achieved a good functional outcome with an mRS score of 2 or less, while 78 patients scored 3 or higher, indicating poorer functional recovery. Investigators excluded individuals lacking a 30-day follow-up, those with concurrent injuries affecting their mRS scores, and patients managed without surgical stabilization.
Bivariate analysis revealed that patients with higher functional impairment at 30 days were older and presented with more severe American Spinal Injury Association (ASIA) impairment scores and longer hospital stays. Specifically, the median age for patients with an mRS score of 2 or less was 46 years, compared to 56 years for those with an mRS score of 3 or higher. Furthermore, procedures performed within 24 hours of hospital admission did not reach statistical significance in separating the two recovery groups, with 23% of the better-outcome cohort and 32% of the poorer-outcome cohort receiving early intervention.
Multivariate Logistic Regression Identifies Age and ASIA Impairment as Independent Predictors
Multivariate logistic regression identified specific clinical variables independently associated with a 30-day mRS score of 2 or less. A five-year increase in patient age decreased the odds of a good functional outcome by a factor of 0.87. Conversely, a one-point increase in the baseline ASIA impairment score increased the odds of achieving an mRS score of 2 or less by 3.45. Operating less than 24 hours after presentation yielded an adjusted odds ratio of 0.82, which did not reach statistical significance for predicting short-term functional recovery.
Most patients in the cohort presented with milder injuries. The study authors noted that these findings contrast with certain previous meta-analyses favoring early decompression, yet align with other retrospective and randomized controlled trials showing no significant difference in neurological outcomes based strictly on surgical timing.
Frequently Asked Questions About the Baylor Scott & White Study
Why did researchers choose the Modified Rankin Scale for this spinal injury study?
Investigators selected the Modified Rankin Scale given the predominance of patients with relatively mild neurological impairment in the cohort to assess overall functional status following surgical intervention.
How was early surgical intervention defined in the analysis?
Researchers defined early surgical intervention as any operation performed within 24 hours of hospital presentation. Because exact injury timestamps were not consistently documented in electronic medical records, timing was measured relative to hospital arrival rather than the moment of trauma.
What limitations did the study authors identify in their findings?
The study’s retrospective design at Baylor Scott & White Medical Center and its sample size of 147 patients limited the ability to detect smaller effects on functional outcomes. Investigators also focused strictly on short-term outcomes at 30 days and lacked sufficient representation of patients with severe ASIA A through C injuries.
