Despite universal coverage under a provincial health plan, the residents of Ontario, Canada, still bear some costs for outpatient care, particularly for prescription drugs. The objective of this study was to determine the financial and nonmonetary costs borne by patients presenting at a dermatology clinic in an academic centre, and to assess the extent to which these costs were problematic. Consecutive new patients in a 6-week period were asked to complete a self-administered questionnaire of which 86 of 140 questionnaires (61%) were returned for analysis. The mean total cost to patients was C$28.92 (range $0 to $177.00). Medications were the largest expense (mean $35.66 for those receiving medication). Despite relatively prompt referrals (mean 12.4 days) and short in-office waiting time (mean 26.5 minutes), there was a trend for subjects to rate time costs as more problematic than monetary costs. Patients attending a dermatology clinic bear variable monetary and nonmonetary costs. For some patients these costs may have the potential to impair access to care.
