Recently, Tuscany regional government has promulgated (Regional law n. 464/07) guidelines for setting up suitable sanitary rooms for patients allergic to latex. These guidelines enforced the managers of the Tuscany Local Health Units to promote educational activities and a correct methodology for the safe management of both health workers and patients who need latex-free diagnostical and/or therapeutical procedures. An other Regional law (n.345/05) had previously enforced all the Tuscany Local Health Units managers to implement and update a Registry of every latex-allergic patients ever hospitalized in their own local facilities. Since 2002 a multi-disciplinary task force of health operators, lead by the Preventive Medicine Section, has been elaborating and implementing a plan for the safety of latex-allergic patients of the Pisa University Hospital, along with a Registry where each of these patients were recorded. Moreover, since 2005 under the responsabilities of the staff of the Preventive Medicine Section, another Registry has been implemented and updated. In this Registry all the Hospital employees who have been diagnosed a latex allergy, through the medical exams performed within the occupational medical surveillance activity, have been filed. In this study we report the results of this preventive activity both aimed at patients and heatlh operators safety.
