A comprehensive database on drug assements and HTAs in Spain. Market access and its impact on decision making. Objectives: (1) To provide a comprehensive overview on HTA and its increasing impact on market access of these new drugs and technologies in Primary Healthcare Centers (PHCs) and hospital. (2) To offer an effective tool to identify new and current assessments published in Spain on your product and competitors focused on the outcome measures used for its recommendations in its specific area; PHCs or hospitals. (3) To assess the real impact of a recommendation on prescription patterns in daily practice. Key messages: (1) There are numerous drug unit departments of CCAAs and collaborations between CCAAs (CmEVN) and hospitals (GENESIS) that perform drug assessments, each using different guidelines and protocols for their assessments. (2) Spain also has one national HTA agency and several regional HTA agencies. Publication of HTAs has been more structured with the founding of AUnETS from which all agencies are member. (3) Despite all initiatives to collaborate more on drug assessments and HTAs, a lot of reports and their recommendations are published at a regional or hospital level. (4) Investigation of the impact of drug assessments and HTAs on a regional and hospital level therefore is crucial for the successful market access of a new drug or technology. (5) Knowledge on the scientific evidence and outcome measures to be investigated (e.g. efficacy, effectiveness, safety, costs, cost-effectiveness, budget impact etc.) is important to guarantee a successful appraisal. (6) Evaluation of the ranging impact of recommendations on prescription in daily practice in different settings; e.g. one region versus another region etc.
