Before you get your hopes up I will not be revealing the intimate details of a viva but I will attempt to convey some of the thought processes that are employed in the creation of a viva. I can only speak for myself here but I suspect my colleague examiners do similar things.
It begins with an idea (as do most things) which is often formed during the actual viva exams. I think to myself, “Gee the candidates don’t know much about basic propofol pharmacokinetics.” Often this thought is engendered as I watch a colleague examine on a particular topic. I like to examine on topics that satisfy a few criteria:
- I think anaesthetists should know this stuff
- The topic is clinically relevant (hopefully these two aren’t mutually exclusive)
- I have seen a knowledge deficit about the topic in my trainees (if they already know it then someone else can ask them that!)
- The ‘answers’ or responses I want need to be in the set texts (this can be quite difficult and has scuppered a few viva ideas along the way)
- Another person with a FANZCA would at least understand most of what the viva was getting at
- The nature of the topic lends itself to being asked in a viva format
Once I have the idea I write down what the main points I want candidates to demonstrate an understanding of are. (I also need to make sure there is a learning objective pertaining to the viva!!) Each viva topic is only five minutes long so the path to pass responses needs to be direct and hopefully short. Next I hit the books and confirm that the topic is adequately covered. Occasionally I discover that my understanding of the topic is at odds with what the books say! Not uncommonly I may have to look at six different books and it is frustrating for all of us if they say six slightly different things. Next I need to formulate the questions to get the information I want. Each viva should ideally start with a simple and brief question to allow the candidate to answer the opening question correctly and begin in a good frame of mind. So, for a propofol PK viva I might ask “What is the induction dose of propofol for a healthy unpremedicated 20 year old?” Subsequent questions need to flow on naturally from the opening question. I like a diagram or two in a viva but it needs to be simple and easily drawn. Sometimes it may be better to provide a diagram. It may be deliberately incomplete. Lastly I run through the viva myself a few times to check the timing and make sure the flow of the viva is alright. Then the real hard work starts. Part 2 will elaborate.
