This paper describes a study aiming to investigate the opinions of administrative personnel concerning the effectiveness of a cost sharing mechanism (of euro 5/visit) at public hospitals' outpatient departments. Data was derived through a structured questionnaire (developed by the researchers) which appealed to 112 administrative directors of public hospitals. Results highlighted a positive attitude concerning the function of the cost – sharing mechanism at public hospitals, a rather fair measure for the users (vulnerable groups are excluded) which probably is enhancing the monetary flow in public hospitals.
