International Survey
We have been challenged with many questions over the years mostly on how to rank some postoperative events. A comprehensive survey will be designed to identify such challenging points. These points are then discussed within a core group (at least FA, MP, AD, MAP, PAC) with the aim
to provide some guidance on how to use the CD classification and the CCI® to achieve consistency in the application of both classifications.
The questionnaire consists of three parts: 1) personal identification details, 2) general questions and FAQ on CD classification and CCI®, and 3) specific clinical scenarios.
- General Questions & FAQ:
A selection of questions raised in various benchmark studies, in the weekly morbidity and mortality (M&M) conferences of the University Hospital Zurich and by visitors to the assessurgery.com or cci-calculator.com website who contact us via the contact form.
- Clinical scenarios:
A selection of scenarios that have repeatedly led to discussions at M&M conferences on CD classification and the calculation of the CCI®. Furthermore, scenarios from the 5-year experience paper on CD classification and the 3-year experience paper on CCI® for which no consensus could be found among the survey participants.
We defined 7 groups of clinical scenarios:
1. Complications requiring repetitive interventions
2. Recurrent complications after intermittent healing
3. Invasive diagnostic interventions
4. Expected sequelae
5. Complications of increasing severity depending one from each other
6. Unrelated Complications/Death
7. Patient referral due to complications
Space will be provided for free text comments in relation to each question and scenario.
Panel of international academic surgeons invited based on a broad network of the authors.
- Sample Size Calculation:
Not needed, as consequences are only adjustments.
- Analysis of the survey:
First a descriptive analysis will be performed. Then a core group consisting of the co-authors (FA, MP, AD, MAP, PAC) will meet and discuss all questions and scenarios of the survey. Based on the survey results and the discussion, the core group will finally make a classification recommendation for all questions and scenarios.
Survey participants who leave valuable comments on a question or scenario will be contacted personally, if necessary, and included in the discussion.
