All MT patients above 13 years of age regardless of cause of bleed were included in the study from December 2015 to October 2017 accounting for a total of 61 patients. Subgroup categorization of study population was done, and physician-driven ratios of the blood components were calculated for each case.

Efficient communication existed between the treating physicians and transfusion.
