Health Technology Assessment is a structured form of analysis based on evidence and research that generates information on clinical and cost-effective health technologies. In the field of health, technology means any intervention that can be used to improve health, prevent, diagnose or cure a particular disease, rehabilitation programs, long-term care, and more. The main questions asked when conducting a health technology assessment are: Does the technology work ?, For whom she works?, What is the benefit for the individual ?, At what price ?, How does it compare to alternatives ?. In the medical practice four main components have been adopted in the health technology assessment - 1. Evaluation of the clinical efficiency of the health technology; 2. Economic analysis of health technology; 3. Analysis of the budgetary impact; 4. Assessing the social, ethical and organizational aspects of health technology. The information provided by HTA should be used to make informed health policy decisions regarding investments (or denials) in healthcare technology.
