The latter is more convenient because routinely collected by clinicians for administrative reasons. To exploit this advantage a proprietary program that maps ICD-9-CM into AIS codes has been used for many years. Recently a program called ICDPIC trauma and developed in the USA has become available free of charge for registered STATA users. We compared the ICDPIC calculated Injury Severity Score ISS with the one from direct prospective AIS coding by expert trauma registrars dAIS . Methods The administrative records of the 289 major trauma cases admitted to the hospital of Udine-Italy from 1 July 2004 to 30 June 2005 and enrolled in the Italian Trauma Registry were retrieved and ICDPIC-ISS was calculated. The agreement between ICDPIC-ISS and dAIS-ISS was assessed by Cohen s Kappa and Bland-Altman charts. We then plotted the differences between the 2 scores against the ratio between the number of traumatic ICD-9-CM codes and the number of dAIS codes for each patient DIARATIO . We also compared the absolute differences in ISS among 3 groups identified by DIARATIO. The discriminative power for survival of both scores was finally calculated by ROC curves. Results The scores matched in 33 272 patients k and when categorized in 80 272 k . The Bland-Altman average difference was limits minus to plus . ICDPIC-ISS of 75 was particularly unreliable. The differences increased p as DIARATIO increased
