Background & Objectives: Severe traumatic brain injury is one of the leading causes of mortality and morbidity.Efficient management of severe traumatic brain injury demands a specialty driven focused intensive care. We developed our model of closed ICU driven by Neurosurgical Neurointensivist and the corollary to thiscommitment is a TBI patient centered Neurocritical care with the capacity and capability to deal with most of the neurological illnesses.Materials & Methods: A prospective study was conducted to find out the impact of the establishment of closed system of neurocritical care on 5 year mortality of severe TBI. Total 1288 patients met the inclusion criteria, which were enrolled. Tabulation was done for gender, age range, Glasgow outcome scale and mortality.Results: It was observed that mortality reduced from 47% to 35% over a span of five years. The most common age range was 30-40 years, which is the most productive group of any population. Bed sore incidence is always on rise in any ICU. After the implementation of SOPs based management and increase in nursing staff theincidence of bedsore also showed a detrimental pattern from 35 % to 19%.Conclusion: Neurocritical care unit is proven to be an integral part of any neurosurgical unit and this closed system of NCC unit provide best SOP based care with significant reduction in mortality of patients with STBI.
