Brief summary
Aim of the study is to evaluate, whether the self administered quality of recovery (QoR-9) questionnaire can predict postoperative complications after non-cardiac surgery and whether preoperative risk estimates can be improved by implementation of the QoR-9 as postoperative screening tool.
Detailed description
The QoR-9 as established patient-centred outcome measure, which is validated in German language, is surveyed preoperatively, as well as on postoperative day 1 and 3 after non-cardiac surgery. We showed in a pilot study that this score reveals a high sensitivity to detect patients with a disturbed health status through a detailed and time-consuming physical examination.We want to evaluate if short screening tools can be used to categorize patients with increased risk for developing postoperative complicationsTherefore, patients undergoing non-cardiac surgery are informed preoperatively about the study and written informed consent is obtained. Afterwards, the QoR-9, as well as validated preoperative risk scores are obtained. Relevant intra- and immediate postoperative factors are recorded. On postoperative day 1 and 3 patients perform the QoR-9. Postoperative complications during hospital stay are determined using the Clavien Dindo score by searching the patients 'record. After 6 months the patients are contacted via telephone and the QoR-9 is obtained. 6-months mortality is determined.
Interventions
DIAGNOSTIC_TESTQoR 9 Questionnaire
The QoR-9 as established patient-centred outcome measure, which is validated in German language, is surveyed preoperatively, as well as on postoperative day 1 and 3 after non-cardiac surgery. Postoperative complications are evaluated using the Clavien-Dindo Score. A follow-up is intended after 6 months. Preoperative risk is estimated using the ASA (American Society of Anesthesiologists) and the POSPOM (Preoperative Score to predict postoperative mortality) score.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative Complications evaluated by Clavien- Dindo Score | Date of Surgery till Discharge from Hospital (approximately 30 days) | Nine domains are evaluated: Pulmonary, infectious, renal, gastrointestinal, cardiovascular, neurological, wound, haematological and pain. Each domain is graded between grade I and V (death of a patient). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| hospital mortality | Date of Surgery till Discharge from Hospital (approximately 30 days) | Rate of Mortality among study patients |
| 6-month mortality | 6 month after date of surgery | Mortality among patients 6 months after surgery |
| Superiority of QoR-9 questionnaire against common Outcome Score | Date of surgery until 6 month follow-up | Comparison of different risk estimates and Outcome Scores |
