In this context, the Health Technology Assessment (HTA) is a key tool able to provide policy makers with objective data in order to take the best choices in a perspective of efficiency, effectiveness, and equity in healthcare. The main objective was to develop a common HTA procedure in order to facilitate the decision making process of innovative technologies acquisition. Five piedmont centers were involved. The evaluation process provided several steps: analysis of clinical need, analysis of technology effectiveness and description of the organizational and economic impact.
