The goal of this study was to see if the Canadian CT Head Rule (CCHR) was valid in cases of minor Traumatic Brain Injury (TBI) in an Indian emergency room. The patterns of neuroradiology references between the Emergency Physician (EP) and the neurosurgeon were compared as a secondary goal. Between July 2019 and July 2020, the study was conducted prospectively. Patients who met the inclusion criteria were given CCHR and the results were recorded. For the ultimate decision, the neurosurgeon was consulted. In the event of a disagreement between the neurosurgeon and the EP, the neurosurgeon made the neuro-radiology decision. The CCHR offers 100% sensitivity as a screening tool for individuals who need CT brain scans due to a TBI, while the specificity is low (45.8%). In comparison to neurosurgeons, EPs had a better level of awareness and inclination to use CDRs in situations of minor TBI to guide the decision for neuro-radiology. Residents at the emergency department said they felt safe using the rule through a smartphone application.
