- Prospective evaluation of the effect of a new co-payment for specialists consultations on actualization of referrals (2,432 patient), was examined. Actualization of the appointment, reasons for not actualizing, and sociodemographic characteristics were recorded. Actualization was 85.1% in community consultation clinics and 91.7% in hospital outpatient clinics. The main reasons for non actualization were: inability to reach the clinic (53.4%), the problem had resolved (15%), and co-payment (2%). In addition, 19.1% stated that they did not actualize a past consultant visit due to co-payment. Referring physicians noted that co-payment had some effect on their decision, especially with the elderly or lower income patients. A relatively small compulsory co-payment was not found to have a long term effect on utilization of specialists’ services.
