[Is polytrauma treatment in deficit in the aG-DRG system?]

[Severe injury type procedures-Influence of the cipher 11 "complications" and the COVID-19 pandemic on a center for maximum care of severe injuries]

INTRODUCTION

Ensuring the best treatment options for injured patients (healing process, Heilverfahren, HV) is the main goal and responsibility of the German statutory accident insurance (DGUV). The injury type catalogue is the tool to guide the HV. The development of the number of cases treated in a center for severe injury type procedures, the effects of the cipher 11 "complications" of the catalogue and the effects of the COVID-19 pandemic are presented.

METHODS

A retrospective study of all patients treated in the context of the DGUV from January 2019 to December 2021 was carried out. The number of cases before and during the legal lockdown actions were compared. The case mix index, the mean number of operations, the mean time in the operating room and the hospital stay were analyzed. Additionally, the cases under the cipher 11 were classified according to the specific anatomical regions.

RESULTS

Out of 2007 cases 67% were classified as severe injury type procedures (SAV). Of these cases 51% were categorized to the cipher 11 of the injury type catalogue. Complications were observed particularly in the anatomical regions of the shoulder girdle, elbow, hand, knee, ankle joint and foot. These complex cases are economically not sufficiently represented. During the governmental COVID-19 lockdown actions, the number of patients treated in the context of the DGUV significantly decreased.

CONCLUSION

The injury type catalogue is used effectively in the catchment area of the present trauma center. Most of the cases treated in the present trauma center are severe injury type procedures; however, more than half of these cases are classified as complications. This development might show the need for a structural change or an adjustment of the HV. The current comments on the injury type catalogue offer important definitions and specifications; however, the conciseness of the entire catalogue should be maintained.

[Influence of the general data protection regulation on data quality in registry data collection : Selection bias due to data protection requirements and the impact on key indicators for measuring the quality of care in a level 1 trauma center]

BACKGROUND

Due to the new general data protection regulations (GDPR), the requirements for correct patient information on the documentation of pseudonymized data in a registry have increased enormously. In particular, written consent applies to the TraumaRegister DGU® as it is not always possible to get written permission from severely injured patients in acute situations. Therefore, the study aimed to investigate the influence of undocumented cases due to a lack of clarification on the standardized mortality rate (SMR).

MATERIAL AND METHODS

In 2019, 274 patients meeting the criteria of the baseline dataset were retrospectively recorded. In the remaining 197 patients, the RISC II score could be calculated in all cases. In addition, due to state-specific law, all deceased patients were documented in our trauma center.

RESULTS

In this study with 197 primary care patients (72% male), 147 (74,6%) were informed and gave permission or died and were subsequently documented. The predicted mortality, actual mortality and SMR were 18.5%, 19.0% and 1.03, respectively. For patients who were not informed (n = 50), the predicted mortality, actual mortality, and SMR were 7.0%, 0% and 0. When these cases are included, the SMR is significantly more favorable at 0.93.

CONCLUSION

Due to the lack of written consent from surviving patients, only about 75% of all patients at Leipzig University Hospital could be documented for the TraumaRegister DGU®. On the other hand, since the local legal situation permits registry documentation of deceased patients, this has a detrimental effect on the standardized mortality rate (SMR), which is about 10% higher in our collective than it actually is.
