Introduction:

The HAISS (Herramienta de Aprendizaje ISS) program was created to enhance the feasibility and learning of trauma severity scores AIS (Abbreviated Injury Score) and ISS (Injury Severity Score).

Objective:

Get a computer tool that promotes learning and facilitate proper use of AIS and ISS.

Material and methods:

A sample of 40 orthopedic residents from 1st to 4th grade from 4 hospitals of the Ministry of Health was taken. A prospective longitudinal study was conducted with analytical statistics. 10 clinical cases for obtaining ISS by AIS score were delivered, this was done with the AIS Manual 2005 update 2008, two questions were conducted to evaluate the feasibility and ease of use, the time to perform was measured. The process was repeated a month later with the HAISS program.

Results:

Using the HAISS program reduced the time to resolve the 10 cases by more than 50%, acceptance by the user of the AIS scale also improved. Reliability to obtain the codification of lesions with AIS did not improve, but it did not affected ISS.

Conclusions:

The HAISS computer program is useful for orthopedic residents to accept the AIS score and ISS score mainly because it improved the ease of use and makes it more user-friendly, it also takes less time to use it.
