Anesthesia Quality Control Indicators of 6 Provinces in Central China

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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.

| number of anesthesia per anesthesiologist |  | through study completion, an average of 1 year | 
| proportion of patients of different American Society of Anesthesiologists physical status (ASAPS) |  | through study completion, an average of 1 year | 
| proportion of emergency non selective anesthesia |  | through study completion, an average of 1 year | 
| proportion of various anesthesia methods |  | through study completion, an average of 1 year | 
| proportion of intraoperative autologous blood transfusion |  | through study completion, an average of 1 year | 
| cancellation of operations after the anesthesia |  | through study completion, an average of 1 year |

| hypothermia in the PACU |  | through study completion, an average of 1 year | 
| unplanned transfer to intensive care unit (ICU) |  | through study completion, an average of 1 year | 
| unplanned secondary tracheal intubation |  | through study completion, an average of 1 year | 
| anesthesia-related death within 24 hours of anesthesia | 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 | through study completion, an average of 1 year | 
| cardiac arrest within 24 hours of anesthesia |  | through study completion, an average of 1 year | 
| severe anaphylaxis during anesthesia |  | through study completion, an average of 1 year | 
| severe neurological complications after intraspinal anesthesia |  | through study completion, an average of 1 year | 
| serious complications of central venipuncture |  | through study completion, an average of 1 year | 
| hoarseness after tracheal catheter extubation |  | through study completion, an average of 1 year | 
| coma after anesthesia |  | through study completion, an average of 1 year |
