title: Assessing the use of the Index of Sedation Need in oral surgery.
abstract: OBJECTIVE
  This article evaluates the use of the Index of Sedation Need in oral surgery.
  
  
  METHODS
  Service evaluation and audit.
  
  
  METHODS
  Oral surgery department of a London dental teaching hospital.
  
  
  METHODS
  Patients attending for oral surgery procedures with sedation which had been arranged without reference to the IOSN tool completed the IOSN and a patient questionnaire. Operators completed a similar questionnaire. The IOSN was calculated and the questionnaire responses analysed using SPSS.
  
  
  RESULTS
  56% of the patients in this study (n = 105) were receiving sedation appropriately according to the IOSN tool. When the questionnaire responses were analysed depending on sedation need, no statistical difference was found using Fisher's exact test or Pearson Chi-Square (p <0.05). Fifty percent of patients who had no need for sedation according to the IOSN tool were considered by the operator to have been untreatable without it.
  
  
  CONCLUSIONS
  This study raises questions over the validity and reliability of the IOSN tool as a method of defining sedation need.
