Retrospective Evaluation of Delirium Data From Previous Study Patients for Studies at the Clinic for Anesthesiology and Intensive Care Medicine CCM/CVK/CBF

Study Overview
=================
Brief Summary
-----------------
Evaluation of several studies of the Clinic for Anesthesiology and Intensive Care Medicine CCM/CVK/CBF to create a register with the delirium data from anesthesiology study patients between 18 - 100 years. The primary purpose of the register is to assess factors influencing the development of delirium. In a subproject, risk factors that may lead to the development of postoperative delirium in the elderly will be evaluated with regard to gender differences using patients from the age of 60 with different surgical procedures. The risk factors examined are based on the evidence-based and consensus-based recommendations of the ESA guideline and literature review. In addition, the delirium incidence rate and the delirium severity is examined regarding gender differences.

| Charlson comorbidity index | Comorbidity scores | Up to 5 years | 
| Lifestyle risks 1 | Consumption of alcohol is measured by AUDIT (Alcohol Use Disorders Identification Tests) | Up to 5 years | 
| Lifestyle risks 2 | Consumption of and nicotine is measured by Fagerström Test for Cigarette Dependence (FTCD). Questionnaire scored 0-10 points with Total Score equal to the sum of all points | Up to 5 years | 
| Lifestyle risks 3 | Consumption of nicotine is measured by Smocking Pack Years (SPY) | Up to 5 years | 
| Lifestyle risks 4 | Previous consumption of nicotine is measured by History of Smoking. | Up to 5 years | 
| Level of education | Level of education is measured by ISCED (International Standard Classification of Education) | Up to 5 years | 
| Quality of life - relatives | Quality of life is measured by CarerQoL | Up to 5 years | 
| Quality of life - self 1 | Quality of life is measured by EQ-5D.An index calculated from the five EQ-5D (3L and 5L) dimensions by attaching specific weights to each severity level in each dimension. | Up to 5 years | 
| Quality of life - self 2 | Quality of life is measured by WHO-5. WHO-5 is a short and generic global rating scale measuring subjective well-being, the respondent is asked to rate how well each of the 5 statements applies to him or her when considering the last 14 days. Each of the 5 items is scored from 5 (all of the time) to 0 (none of the time). The raw score ranges from 0 (absence of well-being) to 25 (maximal well-being). Scores are then converted to a percentage scale from 0 (absent) to 100 (maximal). Higher scores represent greater psychological well-being. | Up to 5 years |
