Is There a Difference in the Mortality Prediction Performance of Two ICISS Approaches for Trauma Patients Admitted to Hospitals in Urban India?

Research question Is there a difference in the mortality prediction performance of two ICISS approaches for trauma patients admitted to hospitals in urban India?

Study design The investigators will conduct a retrospective registry based study.

Setting The data that will be used is from a prospective cohort study named towards improved trauma care outcomes in India (TITCO). It was collected from four public university hospitals in India between October 2013 and January 2015. The hospitals are in Mumbai, Delhi and Kolkata. The two centers in Mumbai were King Edward Memorial Hospital and Lokmanya Tilak Municipal General Hospital. The one in Delhi was Jai Prakash Narayan Apex Trauma Center and the one in Kolkata was the Institute of Post-Graduate Medical Education and Research and Seth Sukhlal Karnani Memorial Hospital.

The data was collected by one trained project officer at each hospital, working eight-hour shifts with a rotating schedule between day, evening and night shifts. Data from patients admitted outside of the shift hours was collected retrospectively within days of arrival to hospital. The patients were followed until discharge, death or to a maximum of 30 days. If discharged, the patients were considered to be alive at 30 days. There was no follow-up after patient discharge or after the 30 days.

Source and method of participant selection Project officers included consecutive patients that presented to participating hospitals. Patients were included either by direct observation during the project officers' shifts or by retrospective data extraction from patient records.
