Brief Summary
DESIGN: Prospective randomised-controlled trial AIM: To determine whether presenting both techniques of general anaesthesia and regional anaesthesia in an unbiased manner, with video media, aids the anaesthetic consent process, compared to standard verbal consent alone. OUTCOME MEASURES Primary outcome: \- Participants' satisfaction regarding the anaesthetic consent process Secondary outcomes:
- Knowledge, attitudes and practices towards anaesthesia
- Participants' choice of anaesthetic technique POPULATION: General adult population (\>18yrs), males and females DURATION: 2 years

Outcome Measures
Primary Outcomes (1)
Patient satisfaction CSQ-8
Client Satisfaction Questionnaire is a questionnaire measuring satisfaction. Response options differ from item to item, but all are based on a four-point scale. Examples include: "How satisfied are you with the amount of help you have received?" (which response options: 1 = "Quite dissatisfied", 2 = "Indifferent or mildly dissatisfied", 3 = "Mostly satisfied", 4 = "Very satisfied"; and, "Have the services you received helped you to deal more effectively with your problems?" (Which has the response options: 4 = Yes, they helped a great deal", 3 = "Yes, they helped somewhat", 2 = "No, they didn't help", 1 = "No, they seemed to make things worse". with an overall score is produced by summing all item responses. For the CSQ-8 version, scores range from 8 to 32, with higher values indicating higher satisfaction.

Study Arms (2)
Standard video verbal consent process
NO INTERVENTIONThe control group will undergo the standard video verbal consent process for both GA and RA for orthopaedic surgery. This will be delivered using a standardised video script that will be generated from existing certified material.
Video assisted consent process
EXPERIMENTALThe intervention group will also be shown the same pre-recorded standard verbal consent, but following this will additionally be shown a specifically recorded video of the anaesthetic process for both GA and RA.
Interventions
The intervention group will also be shown the same pre-recorded standard verbal consent, but following this will additionally be shown a specifically recorded video of the anaesthetic process for both GA and RA. This video will aim to communicate the same information as that found in the traditional verbal consent, using an actor undergoing an anaesthetic to provide context.
