The article presents data on associations and foundations active in health care field in Poland, on the basis of a review of research done by Klon/Jawor Association and the Central Statistical Office. The article also applies to the issue of cooperation between NGOs and governmental adminstration in the health area and identifies lacking information that is necessary for better planning of national health policy. In Poland there are about three thousand associations and foundations whose main focus is the health care. In 2010, they accounted for about 7% of all non-governmental organizations. Results of representative nationwide surveys from 2008 and 2010 indicate that the NGO's active in the field of health care have, in most cases, legal form of associations. Almost half of the organizations declared national or international scope of action. Headquarters of most organizations were mainly in the cities, and only, one in twenty in the village. Most organizations were located in the mazowieckie province and a significant fraction of them was in Warsaw itself. Organizations were stood out by a relatively large number of personnel on the background of the entire NGO sector. Half of the organizations employed paid workers, the majority also collaborated with volunteers who were not members of the organization. More than a third of organizations dealt with the rehabilitation, therapy and long-term care, and about 1/3 dealt with prevention, health promotion and education, and blood donations. World Health Organization indicates the need for systematic collection of data about the role of the nongovernmental sector in health. In Poland, legal regulations require the public institutions and organizations to cooperate with NGOs to achieve health objectives. In spite of relevant data on NGOs in the field of health care in Poland, the necessary information to assess their potential are still lacking. Recognition of the capacity and limitations ofNGOs could enable better planning of national health policy.
