Knowledge about the meaning of treatment is one of the aspects of good patient cooperation with a doctor. Patients of the maternity ward do not show satisfactory knowledge about the used supplementation with vitamins D and K. The preliminary study suggests that there is a group of patients, which the pharmaceutical advice related to the appropriateness of supplementation can be important. It is a group of up to 30% of people who openly declare a complete lack of knowledge about the legitimacy of the treatment. Lack of information about treatment can be treated as some failure to comply with patient’s rights, however, at the preliminary examination stage, the reasons for lack of knowledge cannot be determined.

The education of patients in the hospital ward is a task carried out in some countries and a potential new task in the realities of the Polish healthcare system. It would pose specific educational requirements to pharmacists, emphasizing the practical use of knowledge and pointing to the special significance of interpersonal skills, which, in the opinion of the authors, are more important than the formal specialization, sex or age of the person implementing the discussed pharmaceutical service.
