Approximately, one in three computed tomography (CT) scans performed for head injury may be avoidable. We evaluate the efficacy of the Canadian CT head rule (CCHR) on head CT imaging in minor head injury (MHI) and its association of Glasgow Coma Scale (GCS) and structural abnormality.
We conducted a prospective cross-sectional study from May 2018 to October 2019 in the Department of Emergency Medicine, Pushpagiri Institute of Medical Sciences and Research Centre, Thiruvalla, Kerala. The CCHR is applied to patients with MHIs (GCS 13-15) after initial stabilization and it is ascertained, if they require a non-contrast CT head and imaging is done. For those who do not require CT head as per the CCHR are excluded from this study. After imaging the patients who have a positive finding on CT head are admitted and followed up if they underwent any neurosurgical intervention, those with no findings in CT head are discharged from the hospital. A total of 203 patients were included during study period.
A total of 203 patients were included in study with mean age of 49.5 years. Approximately, 70% (142) were male. Sensitivity of CCHR for predicting positive CT finding in the present study sample was 68% and specificity was 42.5%.
Canadian CT head rule is a useful tool in the Emergency Department for predicting the requirement of CT in patients with MHI. Canadian CT head rule can reduce the number of CT scans ordered following MHI in ED, thus improving the healthcare costs.

因头部受伤而进行的计算机断层扫描（CT）中，约三分之一可能是不必要的。我们评估了加拿大头部CT规则（CCHR）在轻度头部损伤（MHI）患者头部CT成像中的有效性，以及它与格拉斯哥昏迷量表（GCS）和结构异常的关联。
2018年5月至2019年10月，我们在喀拉拉邦蒂鲁瓦拉市普什帕吉里医学科学与研究中心急诊科进行了一项前瞻性横断面研究。CCHR应用于初始稳定后的MHI患者（GCS 13 - 15），确定他们是否需要进行非增强头部CT并完成成像。根据CCHR不需要进行头部CT的患者被排除在本研究之外。对头部CT有阳性发现的患者进行成像后，如果他们接受了任何神经外科干预则入院并进行随访，头部CT无发现的患者则出院。研究期间共纳入203例患者。
本研究共纳入203例患者，平均年龄49.5岁。大约70%（142例）为男性。在本研究样本中，CCHR预测CT阳性发现的敏感性为68%，特异性为42.5%。
加拿大头部CT规则是急诊科预测MHI患者CT需求的有用工具。加拿大头部CT规则可减少急诊科MHI后开具的CT扫描数量，从而降低医疗成本。
