The goal of the project was to increase the effectiveness of chief nurses through a further training programme in the field of management. The team in Szeged (Hungary) chose as their area of interest, human resource management, as in this field, it is possible to achieve the greatest improvement with the smallest financial investment. We measured fluctuations and the absenteeism of nurses, changes in their qualifications, and nurse and patient satisfaction at the beginning and end of the period studied. Almost all parameters showed improvement by the end of the tested period. A book of two volumes (available on the WEB in English and in French) was prepared containing the recommendations of EU.
