Objective: Despite neurotrauma treatment practices comprising a significant amount of neurosurgical work for secondary medical service centers, little attention has been placed on neurotrauma cases and evaluation of current neurotrauma treatment practices is limited. Therefore we investigated current neurotrauma practices in our hospital located in a Japanese suburban city.
Method: We analyzed 439 patients with traumatic brain injury (TBI) admitted to our hospital between April 2004 and October 2010. Patients were divided into three groups based on the Glasgow Coma Scale (GCS) score on admission: mild TBI (GCS 14 – 15) in 252 patients (57.4%), moderate TBI (GCS 9 – 13) in 116 patients (26.4%), and severe TBI (GCS 3 – 8) in 71 patients (16.2%). Age, gender, alcohol consumption, cause of injury, cranial CT findings, neurosurgical procedure, length of hospital stay, and clinical outcome were analyzed.
Results: The average age of the patients was 59.2 years old. Male patients comprised 65%. Alcohol consumption was reported in 81 cases (18.5%), most of them with moderate TBI. Fall (208 cases, 47.4%) was the most frequent cause of injury, followed by traffic accident (115 cases, 26.2%) and high fall (73 cases, 16.6%). Acute subdural hematoma (174 cases, 39.6%) was most frequently seen in cranial CT findings on admission, which significantly increased with severity. A neurosurgical procedure was performed for 70 cases (15.9%), of which 15 (6.0%) were mild TBI and 18 (15.5%) were moderate TBI. The average hospital stay was 20.8 days, which significantly increased with severity. The overall rate of favorable outcome was 82.7%, and mortality was 8.2%; outcome deteriorated with severity.
Conclusion: Some mild and moderate TBI cases had deteriorated and required surgery or resulted in death. These findings suggest that cautious treatment is necessary even in mild to moderate TBI cases which are often encountered in secondary medical service centers.
