The investigators are aimed to evaluate the anaesthesia-related quality control indicators and adverse events, in terms of its incidence, changes, causes, risk factors and preventability in Central China, using a series of annual surveys.
The investigators prospectively collected information on patient, surgical, anaesthesia, and hospital characteristics for all anaesthesia procedures performed in all certified facilities in Central China. All available data of patients who had anaesthesia were gathered monthly from anaesthesia quality control groups that provide services to all certified facilities and were reviewed. All anaesthesia-related adverse events were scrutinized consecutively to determine their root causes and preventability. The incidence and patterns of anaesthesia-related quality control indicators and adverse events were analysed.

Anesthesia-related deaths were diagnosed and reported timely by the data-quality-control staffs at all AQCC certified facilities, according to the time and code of death. Time: within 24 h of anesthesia induction Code: International Classification of Diseases, 10th Revision for medical conditions related to anesthesia or anesthetics was grouped into four categories: (1) complications of anesthesia during labor (24 hours after anesthesia); (2) overdose of anesthetics for surgical purposes; (3) adverse effects of anesthetics in therapeutic use; and (4) other complications of anesthesia in surgical and medical care
