[Knowledge of the cost of the treatments delivered from the Hospital Pharmacy Department and perception of the health status].

Objective: To assess the influence of the knowledge of the financial cost of the treatment and perception of the patient of his/her health status and the health care received from the Hospital Pharmacy Department (HPD).

Method: During a four-month period, from July to October of 2009, a questionnaire was provided to all the patients coming to the Hospital Pharmacy Department to gather their medications, except for those starting their therapies. The patients returning the completed questionnaire at a next visit were provided with the second part, in which they were informed on the monthly cost of their treatments and some questions from the main questionnaire were asked again.
