Both increasing competition between hospitals and growing demands for quality by patients and health insurances require a good knowledge of patients' needs and expectations. For this reason the hospital management organized a survey during Open Day in the hospital. The visitors were asked to find facts about their expectations concerning a potential stay in a hospital. The results of this survey show the importance of hospital staff's communication skills. Moreover, the results indicate that structural changes in a hospital must be aimed at patient's needs and requirements. Only in this manner can the expectations of potential patients be met to ensure high patient satisfaction.
