Brief summary

Aim: To determine the relationship between quantitative and qualitative risk perceived by patients presenting for anaesthesia. Participants will be recruited before their preanaesthetic consultation in the preadmission clinic and will be above 18yrs old. Methods: Participants randomised as to the order in how anaesthesia risk is presented. Group A will be asked to correlate verbal descriptions of risk with numerical descriptions and then be asked to correlate numerical descriptions with verbal ones and Group B will do it the other way round. All participants will be asked general demographic information and which method of describing risks they prefer and whether they would like a discussion of risks to be included in the preanaesthetic consultation. Expected Outcomes: to be able to correlate verbal descriptions of risk with numerical descriptions in order to develop a useful set of words that can be used to communicate risk more clearly.

Aim: To determine the relationship between quantitative and qualitative risk perceived by patients presenting for anaesthesia. Participants > 18yrs will be recruited before their preanaesthetic consultation in the preadmission clinic. Methods: All participants in this study will be asked the same questions. The order of questioning will be allocated as per the randomisation sequence. All participants will be asked both sets of questions. Group A will be provided with a series of words describing risk such as 'rare, 'uncommon' 'common' 'frequent' and asked to choose which numerical descriptor eg 1:1000, 1:100 etc best applies to the verbal terms. Group B will be provided with the numerical descriptors of risk first and then asked the most appropriate word from a list best describing the meaning as per Group A. There will be no washout period. The survey will take approximately 10 mins total. All participants will be asked general demographic information and which method of describing risks they prefer (numerical or verbal) and whether they would like a discussion of risks to be included in the preanaesthetic consultation. Expected Outcomes: to be able to correlate verbal descriptions of risk with numerical descriptions in order to develop a useful set of words that can be used to communicate risk more clearly when consenting patients for their anaesthetic.
