Variation in neurosurgical intervention for severe traumatic brain injury: The challenge of measuring quality in trauma center verification.

ABSTRACT:

Background

Intracranial pressure monitor (ICPm) procedure rates are a quality metric for American College of Surgeons trauma center verification. However, ICPm procedure rates may not accurately reflect the quality of care in TBI. We hypothesized that ICPm and craniotomy/craniectomy procedure rates for severe TBI vary across the United States by geography and institution.

Methods

We identified all patients with a severe traumatic brain injury (head Abbreviated Injury Scale, ≥3) from the 2016 Trauma Quality Improvement Program data set. Patients who received surgical decompression or ICPm were identified via International Classification of Diseases codes. Hospital factors included neurosurgeon group size, geographic region, teaching status, and trauma center level. Two multiple logistic regression models were performed identifying factors associated with (1) craniotomy with or without ICPm or (2) ICPm alone. Data are presented as medians (interquartile range) and odds ratios (ORs) (95% confidence interval).

Results

We identified 75,690 patients (66.4% male; age, 59 [36-77] years) with a median Injury Severity Score of 17 (11-25). Overall, 6.1% had surgical decompression, and 4.8% had ICPm placement. Logistic regression analysis showed that region of the country was significantly associated with procedure type: hospitals in the West were more likely to use ICPm (OR, 1.34 [1.20-1.50]), while Northeastern (OR, 0.80 [0.72-0.89]), Southern (OR, 0.84 [0.78-0.92]), and Western (OR, 0.88 [0.80-0.96]) hospitals were less likely to perform surgical decompression. Hospitals with small neurosurgeon groups (<3) were more likely to perform surgical intervention. Community hospitals are associated with higher odds of surgical decompression but lower odds of ICPm placement.

Conclusion

Both geographic differences and hospital characteristics are independent predictors for surgical intervention in severe traumatic brain injury. This suggests that nonpatient factors drive procedural decisions, indicating that ICPm rate is not an ideal quality metric for American College of Surgeons trauma center verification.

Project description:BackgroundThe probability of undergoing surgery after severe traumatic brain injury (TBI) varies significantly across studies and centers. However, causes of this variability are poorly understood. We hypothesized that intoxication may impact the probability of receiving an urgent neurosurgical procedure among patients with severe TBI.MethodsWe performed a retrospective cohort study of adult patients admitted to a Level I or II trauma center in the United States or Canada with an isolated severe TBI (2012-2016). Data were derived from the Trauma Quality Improvement Program dataset. An urgent neurosurgical procedure was defined as a procedure that occurred within 24 hours of admission. Multivariable logistic regression was utilized to examine the independent effect of intoxication on a patient's likelihood of undergoing an urgent procedure, as well as the timing of the procedure.ResultsOf the 33,646 patients with an isolated severe TBI, 11,313 (33.6%) were intoxicated. An urgent neurosurgical procedure was performed in 8,255 (24.5%) cases. Overall, there was no difference in the probability of undergoing an urgent procedure between patients who were and were not intoxicated (OR 0.99; 95% CI 0.94-1.06). While intoxication status had no impact on the probability of surgery among patients with the most severe TBI (head AIS 5: OR 1.06 [95% CI 0.98-1.15]), intoxicated patients on the lower spectrum of injury had lower odds of undergoing an urgent procedure (AIS 3: OR 0.80 [95% CI 0.66-0.97]). Among patients who underwent an urgent procedure, intoxication had no impact on timing.ConclusionIntoxication status was not associated with differences in the probability of undergoing an urgent neurosurgical procedure among all patients with a severe TBI. However, in patients with less severe TBI, intoxication status was associated with decreased likelihood of receiving an urgent intervention. This finding underscores the challenge in the management of intoxicated patients with TBI.

Project description:There have been large changes over the past several decades to patient demographics in those presenting with mild traumatic brain injury (mTBI) with intracranial hemorrhage (ICH; complicated mTBI) with the potential to affect the use of neurosurgical interventions. The objective of this study was to characterize long-term trends of neurosurgical interventions in patients with complicated mTBI using 13 years of the National Trauma Data Bank (NTDB). This was a retrospective cohort study of adult (≥18 years) trauma patients included in the NTDB from 2007 to 2019 who had an emergency department Glasgow Coma Scale score 13-15, an intracranial hemorrhage (ICH), and no skull fracture. Neurosurgical intervention time trends were quantified for each ICH type using mixed-effects logistic regression with random slopes and intercepts for hospitals, as well as covariates for time and 14 demographic, injury, and hospital characteristics. In total, 666,842 ICH patients across 1060 hospitals were included. The four most common hemorrhages were isolated subdural hemorrhage (36%), isolated subarachnoid hemorrhage (24%), multiple hemorrhage types (24%), and isolated unspecified hemorrhages (9%). Overall, 49,220 (7%) patients received a neurosurgical intervention. After adjustment, the odds of neurosurgical intervention significantly decreased every 10 years by the following odds ratios (odds ratio [95% confidence interval]): 0.85 [0.78, 0.93] for isolated subdural, 0.63 [0.51, 0.77] for isolated subarachnoid, 0.50 [0.41, 0.62] for isolated unspecified, and 0.79 [0.73, 0.86] for multiple hemorrhages. There were no significant temporal trends in neurosurgical intervention odds for isolated epidural hemorrhages (0.87 [0.68, 1.12]) or isolated contusions/lacerations (1.03 [0.75, 1.41]). In the setting of complicated mTBI, the four most common ICH types were associated with significant declines in the odds of neurosurgical intervention over the past decade. It remains unclear whether changing hemorrhage characteristics or practice patterns drove these trends.

Project description:Bladder rupture occurs in only 1.6% of blunt abdominopelvic trauma cases. Although rare, bladder rupture can result in significant morbidity if undiagnosed or inappropriately managed. AUA Urotrauma Guidelines suggest that urethral catheter drainage is a standard of care for both extraperitoneal and intraperitoneal bladder rupture regardless of the need for surgical repair. However, no specific guidance is given regarding the length of catheterization. The present study seeks to summarize contemporary management of bladder trauma at our tertiary care center, assess the impact of length of catheterization on bladder injuries and complications, and develop a protocol for management of bladder injuries from time of injury to catheter removal. A retrospective review was performed on 34,413 blunt trauma cases to identify traumatic bladder ruptures over the past 10 years (January 2008-January 2018) at our tertiary care facility. Patient data were collected including age, gender, BMI, mechanism of injury, and type of injury. The primary treatment modality (surgical repair vs. catheter drainage only), length of catheterization, and post-injury complications were also assessed. Review of our institutional trauma database identified 44 patients with bladder trauma. Mean age was 41 years, mean BMI was 24.8 kg/m2, 95% were Caucasian, and 55% were female. Motor vehicle collision (MVC) was the most common mechanism, representing 45% of total injuries. Other mechanisms included falls (20%) and all-terrain vehicle (ATV) accidents (13.6%). 31 patients had extraperitoneal injury, and 13 were intraperitoneal. Pelvic fractures were present in 93%, and 39% had additional solid organ injuries. Formal cystogram was performed in 59% on presentation, and mean time to cystogram was 4 hours. Gross hematuria was noted in 95% of cases. Operative management was performed for all intraperitoneal injuries and 35.5% of extraperitoneal cases. Bladder closure in operative cases was typically performed in 2 layers with absorbable suture in a running fashion. The intraperitoneal and extraperitoneal injuries managed operatively were compared, and length of catheterization (28 d vs. 22 d, p=0.46), time from injury to normal fluorocystogram (19.8 d vs. 20.7 d, p=0.80), and time from injury to repair (4.3 vs. 60.5 h, p=0.23) were not statistically different between cohorts. Patients whose catheter remained in place for greater than 14 days had prolonged time to initial cystogram (26.6 d vs. 11.5 d) compared with those whose foley catheter was removed within 14 days. The complication rate was 21% for catheters left more than 14 days while patients whose catheter remained less than 14 days experienced no complications. The present study provides a 10-year retrospective review characterizing the presentation, management, and follow-up of bladder trauma patients at our level 1 trauma center. Based on our findings, we have developed an institutional protocol which now includes recommendations regarding length of catheterization after traumatic bladder rupture. By providing specific guidelines for initial follow-up cystogram and foley removal, we hope to decrease patient morbidity from prolonged catheterization. Further study will seek to allow multidisciplinary trauma teams to standardize management, streamline care, and minimize complications for patients presenting with traumatic bladder injuries.

Project description:BackgroundA minority of persons who have traumatic experiences go on to develop post-traumatic stress disorder (PTSD), leading to interest in who is at risk for psychopathology after these experiences. Complicating this effort is the observation that post-traumatic psychopathology is heterogeneous. The goal of this nested case-control study was to identify pre-trauma predictors of severe post-traumatic psychiatric comorbidity, using data from Danish registries.MethodsThe source population for this study was the population of Denmark from 1994 through 2016. Cases had received three or more psychiatric diagnoses (across all ICD-10 categories) within 5 years of a traumatic experience (n = 20 361); controls were sampled from the parent cohort using risk-set sampling (n = 81 444). Analyses were repeated in samples stratified by pre-trauma psychiatric diagnoses. We used machine learning methods (classification and regression trees and random forest) to determine the important predictors of severe post-trauma psychiatric comorbidity from among hundreds of pre-trauma predictor variables spanning demographic and social variables, psychiatric and somatic diagnoses and filled medication prescriptions.ResultsIn the full sample, pre-trauma psychiatric diagnoses (e.g. stress disorders, alcohol-related disorders, personality disorders) were the most important predictors of severe post-trauma psychiatric comorbidity. Among persons with no pre-trauma psychiatric diagnoses, demographic and social variables (e.g. marital status), type of trauma, medications used primarily to treat psychiatric symptomatology, anti-inflammatory medications and gastrointestinal distress were important to prediction. Results among persons with pre-trauma psychiatric diagnoses were consistent with the overall sample.ConclusionsThis study builds on the understanding of pre-trauma factors that predict psychopathology following traumatic experiences, by examining a broad range of predictors of post-trauma psychopathology and comorbidity beyond PTSD.

Project description:ObjectiveThe effect of surgical treatment for supratentorial spontaneous intracerebral hemorrhage (ICH) and whether it is modified by key baseline characteristics and timing remains uncertain.MethodsWe performed a systematic review and meta-analysis of randomized controlled trials of surgical treatment of supratentorial spontaneous ICH aimed at clot removal. We searched MEDLINE, Embase, and Cochrane databases up to February 21, 2019. Primary outcome was good functional outcome at follow-up; secondary outcomes were death and serious adverse events. We analyzed all types of surgery combined and minimally invasive approaches separately. We pooled risk ratios with 95% confidence intervals and assessed the modifying effect of age, Glasgow Coma Scale, hematoma volume, and timing of surgery with meta-regression analysis.ResultsWe included 21 studies with 4,145 patients; 4 (19%) were of the highest quality. Risk ratio of good functional outcome after any type of surgery was 1.40 (95% confidence interval [CI] = 1.22-1.60, I2 = 46%, 20 studies), and after minimally invasive surgery it was 1.47 (95% CI = 1.26-1.72, I2 = 47%, 12 studies). For death, the risk ratio for any type of surgery was 0.77 (95% CI = 0.68-0.85, I2 = 23%, 21 studies), and for minimally invasive surgery it was 0.68 (95% CI = 0.56-0.83, I2 = 14%, 13 studies). Serious adverse events were reported infrequently. Surgery seemed more effective when performed sooner after symptom onset (p = 0.04, 12 studies). Age, Glasgow Coma Scale, and hematoma volume did not modify the effect of surgery.InterpretationSurgical treatment of supratentorial spontaneous ICH may be beneficial, in particular with minimally invasive procedures and when performed soon after symptom onset. Further well-designed randomized trials are needed to demonstrate whether (minimally invasive) surgery improves functional outcome after ICH and to determine the optimal time window of the treatment after symptom onset.
