Anesthesia-handover Checklist and Perioperative Outcomes in Elderly

Study Overview
=================
Brief Summary
-----------------
With the increasing number of surgical cases, intraoperative handover of anesthesia care is common and inevitable. Verbal handover from one anesthesiologist to another during surgery are being used in many hospitals. However, verbal handover is often an informal, unstructured process during which omissions and errors can occur. It is possible that an improved anesthesia handover may reduce the related adverse events. This study aims to test the hypothesis that use of a well-designed, structured handover-checklist to improve handover quality may decrease the occurrence of postoperative complications in elderly patients undergoing major noncardiac surgery.

Detailed Description
-----------------
It was estimated that more than 9 million patients undergo surgery with a complete anesthesia handover each year worldwide. Verbal handover from one anesthesiologist to another during surgery are being used in many hospitals; and there is no unified patient handover guideline at present. It is well recognized that the transfer-of-care is a point of vulnerability where valuable patient information can be distorted and omitted. A previous study of the investigators showed that handover of anesthesia care was associated with a higher risk of delirium in elderly patients after major noncardiac surgery. The World Health Organization has included communication during patient care handovers among its top 5 patient safety initiatives. It is possible that an improved anesthesia-handover protocol may reduce the related adverse events. Many efforts have performed to optimize handover processes. However, handover quality between anesthesiologists has rarely been investigated. The investigators hypothesize that a well-designed, structured handover-checklist will improve handover quality and reduce the occurrence of postoperative complications.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| A composite incidence of all complications within 30 days after surgery. | Include organ injury (delirium, acute kidney injury, and myocardial injury) within 3 days and other major complications (class II or higher on Clavien-Dindo classification) within 30 days after surgery. | Up to 30 days after surgery. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Intensive care unit admission after surgery. | Intensive care unit admission after surgery. | Up to 30 days after surgery. | 
| Length of stay in the intensive care unit after surgery. | Length of stay in the intensive care unit after surgery. | Up to 30 days after surgery. | 
| Incidence of organ injury (delirium, acute kidney injury, and acute myocardial injury) within 3 days after surgery. | Delirium is diagnosed with the Confusion Assessment Method. Acute kidney injury is diagnosed according to the KDIGO (Kidney Disease: Improving Global Outcomes) Criteria. Acute myocardial injury is diagnosed according to the serum cardiac tropinin I level. | Up to 3 days after surgery. | 
| Incidence of major complications within 30 days after surgery. | Major complications are defined as newly occurred conditions that are harmful to patients' recovery and required medical therapy, i.e., class II or higher on the Clavien-Dindo classification. | Up to 30 days after surgery. | 
| Length of hospital stay after surgery. | Length of hospital stay after surgery. | Up to 30 days after surgery. | 
| All-cause mortality within 30 days after surgery. | All-cause mortality within 30 days after surgery. | Up to 30 days after surgery. |
