RESUMEN
The aim of this study was to describe the evolution of mechanisms to manage the introduction of new medicines and their impact on the health-care system in Scotland. The study was a review of published and unpublished national audits and surveys on the introduction of new medicines in Scotland. Before the Scottish Medicines Consortium (SMC) was established, Area Drug and Therapeutics Committees (ADTCs) played a key role in advising National Health Service (NHS) Boards in Scotland on the use of new medicines. There was evidence of variation in the medicines evaluated and, in some cases, the evidence used leading to different decisions for the same medicine. After the SMC was established, ADTC decisions had become more consistent and comprehensive. The role of ADTCs evolved from evaluation of medicines to assessment of local implications and implementation of SMC advice. There was increased recognition of the importance of monitoring medicine use. This review demonstrated a clear evolution in the evaluation and implementation of new medicines by ADTCs across NHS Scotland. After the SMC was established, more medicines were considered by ADTCs and there was greater consistency in those considered for local implementation. ADTCs have moved from evaluation of new medicines to other aspects of medicine management, including assessment of local implications and implementation of SMC advice.
