The Trauma Audit Filters Trial

An Interrupted Time Series Trial on the Effect of Implementing Trauma Audit Filters on Outcomes of Patients Admitted with Trauma in Urban India



Trauma is emerging as a major threat to population health globally. In addition to prevention, strengthening trauma care is now recognised as imperative to the global health agenda. Substantial research attributes improved trauma outcomes in high income countries to quality improvement programmes. Audit filters, defined as ``pre-identified variables that are routinely tracked to identify whether accepted standards of care are being met'', for monitoring trauma care quality are regarded as one of the most essential components of such programmes; however, there is a paucity of evidence that shows that audit filters are associated with improved outcomes. Therefore, our primary aim is to assess if institutional implementation of audit filters reduce mortality in adult trauma patients. Our secondary aim is to assess if such implementation improve other in and out of hospital outcomes in adult trauma patients.


Controlled interrupted time series trial.


Four university hospitals in India.


Adult patients admitted with history of trauma.

Primary outcome

All cause mortality within 30 days of arrival to participating hospital.

Secondary outcomes

All cause mortality in hospital, within 24 hours and 90 days, quality of life at 90 days, number of hospital free days to day 30, number of intensive care unit free days until day 30, and number of items adhered to in the World Health Organisation's trauma care checklist.
