Are you about to have an operation? Take time to fill in a questionnaire. The questions will help you to talk to your doctor and to prepare for the procedure. Be clear about the reasons for the procedure, possible alternative forms of treatment, and how best to prepare and recover. At the same time, the questionnaire will help you think about the practical arrangements that you need to make in addition to your medical treatment: the people to contact, an advance healthcare directive, care for your pets, etc.
