Opportunities and Limitations of Swiss Polytrauma Registry Data for Scientific Purposes- Registry Data for Scientific Purposes

Study Overview
=================
Brief Summary
-----------------
The aim of the analysis is an evaluation of the current performance of the Swiss Trauma Registry (STR) with respect to providing a reliable basis for (scientific) investigations on the management of trauma patients in Switzerland. The current project tries to address this question by considering central aspects of completeness and by exemplifying the use of the registry for research questions. The aim is to identify potential shortcomings of the registry.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| analysis of data completeness | The STR comprises patient data starting from preclinical management, resuscitation, hospitalization and discharge data as well as data considering 28-day mortality, long-term outcome and cost. The founders agreed on a total of 98 items for analyses. All data sets will be evaluated for completeness of the 98 data points (items). | single time point assessment at baseline | 
| rate of 28 day survival | analysis of patient outcome: rate of patients' 28 day survival | single time point assessment at baseline | 
| length of hospital stay | analysis of patient outcome: length of hospital stay (days) | single time point assessment at baseline | 
| rate of patients receiving intensive care treatment | analysis of patient outcome: rate of patients receiving intensive care treatment | single time point assessment at baseline | 
| rate of patients returning to the previous living situation | analysis of patient outcome: rate of patients returning to the previous living situation | single time point assessment at baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| cost of maintenance of the register | analysis of how many pro-rata salary per cent annually are specifically invested in the maintenance of the register | single time point assessment at baseline |
