Abstract
AimThe aim of the study was to compare the New Orleans Criteria and the New Orleans Criteria according to their diagnostic performance in patients with mild head injury.MethodsThe study was designed and conducted prospectively after obtaining ethics committee approval. Data was collected prospectively for patients presenting to the ED with Minor Head Injury. After clinical assessment, a standard CT scan of the head was performed in patients having at least one of the risk factors stated in one of the two clinical decision rules.Patients with positive traumatic head injury according to BT results defined as Group 1 and those who had no intracranial injury defined as Group 2. Statistical analysis was performed with SPSS 11.00 for Windows. ROC analyze was performed to determine the effectiveness of detecting intracranial injury with both decision rules. p < 0.05 was considered statistically significant.Results175 patients enrolled the study. Male to female ratio was 1.5. The mean age of the patients was 45 ± 21,3 in group 1 and 49 ± 20,6 in group 2. The most common mechanism of trauma was falling. The sensitivity and specificity of CCHR were respectively 76.4% and 41.7%, whereas sensitivity and specificity of NOC were 88.2% and 6.9%.ConclusionThe CCHR has higher specificity, PPV and NPV for important clinical outcomes than does the NOC.
Highlights
Minor head injury (MHI) is one of the most common injury type seen in the emergency departments (ED) [1]
Some authors define MHI as the blunt injury of the head with alteration in consciousness, amnesia, or disorientation in a patient who has a Glasgow Coma Scale (GCS) score of 13 to 15 [3,4], others define it as the blunt injury of the head with alteration in consciousness, amnesia, or disorientation in a patient who has a Glasgow Coma Scale (GCS) score of 14 to 15 [5]
Patients with positive traumatic head injury according to BT results defined as Group 1 and those who had no intracranial injury defined as Group 2
Summary
Minor head injury (MHI) is one of the most common injury type seen in the emergency departments (ED) [1]. Some authors define MHI as the blunt injury of the head with alteration in consciousness, amnesia, or disorientation in a patient who has a Glasgow Coma Scale (GCS) score of 13 to 15 [3,4], others define it as the blunt injury of the head with alteration in consciousness, amnesia, or disorientation in a patient who has a Glasgow Coma Scale (GCS) score of 14 to 15 [5]. Accepted clinical decision rules for detecting life-threatening complications in patients with mild head injury are New Orleans Criteria (NOC) and the Canadian CT Head Rules (CCHR) [3,4,12].
