title: [Investigation and measures for improvement of input error rate in a study of anesthesia-related critical incidents by the Japanese Society of Anesthesiologists].
abstract: BACKGROUND
  The Japanese Society of Anesthesiologists (JSA) started the annual survey of the critical incidents related to anesthesia in 1992. The certified anesthesia-training hospitals, which are more than 700 in Japan, send the questionnaire results to JSA every year. This is a nationwide large-scale survey, in which more than 150 million cases are analyzed per year. The accuracy of each data is essential for such a large data base. In this report, we examined the accuracy of data in our institute.
  
  
  METHODS
  We have examined 2238 cases of anesthesia that we had managed between January 1 and June 30, 2005 in the Hyogo Medical College Hospital. We analyzed the data accuracy regarding the classification of surgical procedures, and anesthesia methods, especially total intravenous anesthesia (TIVA).
  
  
  RESULTS
  The error rate in the classification of surgical procedures was 15.1%. There were three types of errors; incorrect selection (8.1%), suspension by choosing "others" (4.9%), and no selection (2.1%). Inhalation anesthetics were used in 44.6% of cases which had been enrolled as TIVA.
  
  
  CONCLUSIONS
  The high error rate in the classification of surgical procedures and anesthesia methods impair the reliability of data analysis. We expect to discuss further at the JSA meeting regarding the method of the survey.
