Traumatic Brain Injury Epidemiology, risk factors and decision making
The thesis describes epidemiological changes in traumatic brain injury in the Netherlands. Besides this risk factors for and precention of traumatic brain injury is described. Finally existing desicion rules for performing a CT scan in patients with traumatic brain injury are evaluated and the CHIP desicion rule is updated
Emergency medicine training in the Netherlands, essential changes needed
Since 2008, training for emergency physicians (EPs) in the Netherlands has been based on a national 3-year curriculum. However, it has become increasingly evident that it needs to expand beyond its initial foundations. The training period does not comply with European regulations of a minimum of 5 years. Adjusting to this European standard is a logical step. Experience with the 3-year Dutch training scheme has led to the general conclusion that this training period is too short. Recommendations for essential changes and the basis for their development are presented
Mild Traumatic Brain Injury in Elderly Patients Receiving Direct Oral Anticoagulants:A Systematic Review and Meta-Analysis
The aim of this work was to conduct a systematic review and meta-analysis of studies reporting on the risk of traumatic intracerebral hemorrhage (tICH), the course of tICH, and its treatment and mortality rates in elderly mild traumatic brain injury (mTBI) patients using direct oral anticoagulants (DOACs). We consulted PubMed and Embase for relevant cohort and case-control studies with a control group. Two authors independently selected studies, assessed methodological quality, and extracted outcome data. Estimates were pooled with the Mantel-Haenszel random-effects method. We identified 16 articles comprising 3671 elderly mTBI patients using DOACs. Use of DOACs was associated with a reduced risk of tICH compared to the use of vitamin K antagonists (VKAs; odds ratio [OR], 0.44; 95% confidence interval [CI], 0.29-0.65; I2 = 22%) and a similar risk compared to the use of antiplatelet therapy (APT; OR, 0.98; 95% CI, 0.39-2.44; I2 = 0%). Reversal agent use and neurosurgical intervention rate were lower in patients using DOACs compared to patients using VKAs (OR, 0.10; 95% CI, 0.06-0.16; I2 = 0% and OR, 0.37; 95% CI, 0.21-0.67; I2 = 0%, respectively). There was no significant difference in neurosurgical intervention rate between patients who used DOACs versus patients who used APT (OR, 0.58; 95% CI, 0.15-2.21; I2 = 41%) or no antithrombotic therapy (OR, 0.76; 95% CI, 0.20-2.86; I2 = 23%). ICH progression, risk of delayed ICH, and TBI-related in-hospital mortality were comparable among treatment groups. The present study indicates that elderly patients using DOACs have a lower risk of adverse outcome compared to patients using VKAs and a similar risk compared to patients using APT after mTBI
Risk of Intracranial Complications in Minor Head Injury:The Role of Loss of Consciousness and Post-Traumatic Amnesia in a Multi-Center Observational Study
Various guidelines for minor head injury focus on patients with a Glasgow Coma Scale (GCS) score of 13-15 and loss of consciousness (LOC) or post-traumatic amnesia (PTA), while clinical management for patients without LOC or PTA is often unclear. We aimed to investigate the effect of presence and absence of LOC or PTA on intracranial complications in minor head injury. A prospective multi-center cohort study of all patients with blunt head injury and GCS score of 15 was conducted at six Dutch centers between 2015 and 2017. Five centers used the national guideline and one center used a local guideline-both based on the CT in Head Injury Patients (CHIP) prediction model-to identify patients in need of a computed tomography (CT) scan. We studied the presence of traumatic findings and neurosurgical interventions in patients with and without LOC or PTA. In addition, we assessed the association of LOC and PTA with traumatic findings with logistic regression analysis and the additional predictive value of LOC and PTA compared with other risk factors in the CHIP model. Of 3914 patients, 2249 (58%) experienced neither LOC nor PTA and in 305 (8%) LOC and PTA was unknown. Traumatic findings were present in 153 of 1360 patients (11%) with LOC or PTA and in 67 of 2249 patients (3%) without LOC and PTA. Five patients without LOC and PTA had potential neurosurgical lesions and one patient underwent a neurosurgical intervention. LOC and PTA were strongly associated with traumatic findings on CT, with adjusted odds ratios of 2.9 (95% confidence interval [CI] 2.2-3.8) and 3.5 (95% CI 2.7-4.6), respectively. To conclude, patients who had minor head injury with neither LOC nor PTA are at risk of intracranial complications. Clinical guidelines should include clinical management for patients without LOC and PTA, and they should include LOC and PTA as separate risk factors rather than as diagnostic selection criteria
Update of the CHIP (CT in Head Injury Patients) decision rule for patients with minor head injury based on a multicenter consecutive case series
OBJECTIVE: To update the existing CHIP (CT in Head Injury Patients) decision rule for detection of (intra)cranial findings in adult patients following minor head injury (MHI).METHODS: The study is a prospective multicenter cohort study in the Netherlands. Consecutive MHI patients of 16 years and older were included. Primary outcome was any (intra)cranial traumatic finding on computed tomography (CT). Secondary outcomes were any potential neurosurgical lesion and neurosurgical intervention. The CHIP model was validated and subsequently updated and revised. Diagnostic performance was assessed by calculating the c-statistic.RESULTS: Among 4557 included patients 3742 received a CT (82%). In 383 patients (8.4%) a traumatic finding was present on CT. A potential neurosurgical lesion was found in 73 patients (1.6%) with 26 (0.6%) patients that actually had neurosurgery or died as a result of traumatic brain injury. The original CHIP underestimated the risk of traumatic (intra)cranial findings in low-predicted-risk groups, while in high-predicted-risk groups the risk was overestimated. The c-statistic of the original CHIP model was 0.72 (95% CI 0.69-0.74) and it would have missed two potential neurosurgical lesions and one patient that underwent neurosurgery. The updated model performed similar to the original model regarding traumatic (intra)cranial findings (c-statistic 0.77 95% CI 0.74-0.79, after crossvalidation c-statistic 0.73). The updated CHIP had the same CT rate as the original CHIP (75%) and a similar sensitivity (92 versus 93%) and specificity (both 27%) for any traumatic (intra)cranial finding. However, the updated CHIP would not have missed any (potential) neurosurgical lesions and had a higher sensitivity for (potential) neurosurgical lesions or death as a result of traumatic brain injury (100% versus 96%).CONCLUSIONS: Use of the updated CHIP decision rule is a good alternative to current decision rules for patients with MHI. In contrast to the original CHIP the update identified all patients with (potential) neurosurgical lesions without increasing CT rate.</p
