ICT to support Prevention of NCD (Non Communicable Diseases) and occupational diseases R. Gazzarata, D. Vecchio, S. Alloisio, S. Del Buono, M. Giacomini (University of Genoa, Italy) Abstract— The importance of prevention in the fight against illness is not a recent concept. In the last century, thanks to new medical discoveries and to media developments, prevention has get a power never seen before but, despite that, the culture of prevention must be further improved. In this contest one problem is evident: there is too much information available and with different quality. In most cases, high quality information is flooded by many other unsafe sources. Even the user can reach authoritative sources, their organization presentation is often quite confusing. For all these reasons a very sensitive institution, such as Giannina Gaslini Hospital in Genoa, decided to improve the diffusion of prevention culture with a cooperation project among ITC professionals, medical doctors and social affair experts. The main aim of this cooperation is to produce a web based – high quality tool to allow user to get selected information in many fields such as: chemical, physic and biological risk to exposition of dangerous substances, international, national and regional guidelines and laws, workplace safety, risk factors, preventive medicine, life style. In the present paper the ITC structure of the developed tool and the knowledge organization choices are shown. INTRODUCTION w HE prevention as an instrument to reduce illness is not a recent concept. It is born in XVIII century hen Edward Jenner, English doctor and naturalist, used use serum from cows with cowpox to prevent human smallpox, creating the first vaccines in accordance with scientific criteria and recognized by the national English science academy “Royal Society”. In the next century London’s cholera epidemic was defeated thanks to the understanding of the importance of hygiene and the consequent purifying water and the sanitary service improvement. These are only two examples, but they explain the importance of prevention. Thanks to the media development prevention has get a power never seen before: for example let us see cancer and cardiovascular disease cases that represent first and second death causes. T Each year, the American Cancer Society calculates and makes public the number of new cases of cancer and deaths expected in the United States. Moreover, it compiles the most recent data on cancer incidence, mortality, and survival based on the incidence data from the National Cancer Institute, Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and the mortality data from the National Center for Health Statistics. Incidence and death rates are standardized by age to the 2000 United States standard million population. A total of 1,479,350 new cases of cancer and 562,340 deaths caused by cancer were expected to occur in the United States in 2009. Overall, cancer incidence rates decreased in the most recent period in both men (1.8% per year from 2001 to 2005) and women (0.6% per year from 1998 to 2005). This happened largely because of the decreased in major cancer sites in men and women. In men these are: lung, prostate (186320 new cases and 28660 deaths in the US men estimated for 2008 [1-2]), the most common nonskin epithelial malignancy, colon and rectum (colorectum). Otherwise in women the major cancer sites are: breast (second leading cause of mortality among women, and the lifetime risk for developing breast cancer in the United States is one in eight' [3-4]) and colorectum. Overall cancer death rates decreased in men by 19.2% between 1990 and 2005, with a decreases in lung (37%), prostate (24%), and colorectal (17%) cancer accounting for nearly 80% of the total decrease. Among women, overall cancer death rates between 1991 and 2005 decreased by 11.4%, with decreases in breast (37%) and colorectal (24%) cancer accounting for 60% of the total decrease. The reduction in the overall rates of cancer has resulted in the avoidance of about 650,000 deaths over the 15-year period. This great result was possible thanks to studies about causes and factors 79
