This a randomized study in that 6 rheumatologists (30 referrals each) will be randomized to one of two groups: intervention or control. Referring physicians to the intervention group will be faxed a brief Choosing Wisely form (intervention) based upon the recommendations of the Canadian Rheumatology Association's (CRA) Canada Choosing Wisely campaign, while referring physicians from the control group will not receive the form (non intervention). Analysis will be based upon the results of a three question survey faxed to all referring physicians at year one and at year two and on future referrals from the referring physicians to determine if there is a reduction in the group of ordering physicians that received the intervention (Choosing Wisely form).
