Effects of the new injury type catalogue of the German statutory accident insurance on a center for severe injury type procedures

Abstract

Aretrospective study of all inpatients treated in the context of the DAV, VAV and SAV procedures at a SAV center from the 2nd and 3rd quarters of 2018 was carried out. The development of the number of cases, the case mix index (CMI), the mean number of operations, the mean time in the operating room and the length of hospitalization were analyzed. Furthermore, an assessment of the SAV cases was carried out with respect to the new developments and with particularly reference to complications. The total number of inpatients in the context of the DAV, VAV, SAV procedures changed only slightly. There was aclear decrease in DAV cases and arelevant increase in SAV cases. The CMI increased by 47%, the number of surgical procedures by 15%, the mean time in the operating room by 36% and the length of hospitalization by 43%. When converted to a daily operating room unit of 7 h (Tagestischeinheit, TTE) the operating room time increased from 89 to 108 TTE and the length of hospitalization increased from 1028 to 1358 days. Of the 111 SAV cases in the 3rd quarter, 52% were assigned to the catalogue number11 "complications". In comparison to the previous version of the VAV/SAV catalogue, it was now possible to assign all inpatients to asingle category. The modifications of the VAV in the observational period led to an enormous increase in SAV cases. It remains to be seen whether this development is confirmed in subsequent quarters. The increase in CMI, the number of necessary operations, operating room times and duration of hospitalization showed the necessity of these innovations on structural changes of hospitals involved in the treatment of SAV cases.
