The present study aims at assessing the role of epidemiology on health decision-making processes in the public administrations of the Veneto region, north-eastern Italy. In 2003 a questionnaire was mailed to chief-executives of local public health organizations (21 Local Health Units, 2 Public Hospitals), and 18 responded. All public health organizations were practicing Epidemiology, but only 4 had dedicated services. Sixty-two people were working as epidemiologists in public health, but only half played the role for most of their Full Time Employment. Personal educational qualifications were mainly degree in Medicine (62%) and Statistical Sciences (23%). Among physicians, 78% was specialized in Hygiene and Preventive Medicine. The head office of most public health organizations (15 out of 18) appraised epidemiology as fundamental with regard to the health decision-making process, however two thirds of them reported that the epidemiological informative needs were only little or not at all satisfied. To improve the situation, most Public Health Organizations intended to perform educational activities and to use external advisors. In conclusion, Public Health Organizations of the Veneto region appreciated the importance of epidemiology in the health decision-making process. However, few resources were devoted to this field so that informative needs were only partly satisfied.
