BACKGROUND: Consent to therapy is increasingly requested in the form of ''informed consent''. OBJECTIVE: To validate an evidence-based informed consent form for erythropoietin (EPO) therapy and to evaluate patient opinions about the informed consent approach. METHODS: An evidence-based informed consent form was developed as part of the Evidence-Based-Medicine course at the Medical School of Turin, Italy. It was validated by anonymous questionnaires (0-10 analogical scales and open answers) administered to patients at different stages of CKD (19 pre-ESRD, 26 hemodialysis, 12 transplant patients) attending an outpatient unit of the University of Turin, to 8 nurses, and to 26 medical students. RESULTS: All individuals filled in the questionnaire. Interest in a detailed explanation of the therapy was high (median 9), as was comprehension (median 9), with no differences between patients with regard to disease stage (pre-ESRD vs. RRT) or educational level. Prior knowledge of the therapy was affected by the educational level (p=0.013 for the advantages and p=0.004 for the side effects) and the professional role (patients vs caregivers: p=0.009 for the advantages and p<0.001 for side affects); patient knowledge of the advantages (median 6) tended to increase as the disease progressed (p=0.015). The most common response by patients was that informed consent was necessary for all drugs (35.1%); 73.1% of the caregivers considered it necessary only for severe side effects. The preferred modality of consent was discussion with the caregiver during the clinical controls (42% of all cases). CONCLUSIONS: Patient interest in and comprehension of an informed consent form with a detailed explanation of the therapy was high; the caregiver's opinion was still the most valued teaching tool.
