Quality assessment of Major Trauma Registry of Navarra: completeness and correctness.

This study assessed the completeness of the Major Trauma Registry of Navarra (MTR-N) data and their concordance with the patients' medical files. It retrospectively reviewed all the MTR-N cases documented in June and July of 2014 and 2015. For each case, 42 parameters' values were taken from the MTR-N. To assess concordance between the MTR-N and medical files, the same variables values were re-recorded. Data completeness was calculated for all cases and data correctness for those documented in the MTR-N, separately for each variable. The overall average completeness rate for all variables was 92.8%. The percentages of completely missing data ranged from 0% (29 variables) to 76.8% (base excess). The overall average rate of correctness was 98.0%. Exact concordance ranged from 93.0% (7 variables) to 100% (22 variables). This study demonstrates the reliability and validity of the MTR-N data and its effectiveness for quality improvement and research in our community.
