Evidence Following Conditional NICE Technology Appraisal Recommendations: A Critical Analysis of Methods, Quality and Risk of Bias.

Background: The National Institute for Health and Care Excellence (NICE) may approve health technologies on condition of more evidence generated only in research (OiR) or only with research (OwR). NICE specifies the information needed to comply with its request, although it may not necessarily guarantee good quality and timely evidence for re-appraisal, before reaching a final decision.

Aim: This study aimed to critically appraise the methods, quality and risk of bias of evidence generated in response to NICE OiR and OwR technology appraisal (TA) and highly specialised technologies (HSTs) recommendations.

Costs of orphan medicinal products: longitudinal analysis of expenditure in Wales.

Background: The Orphan Regulation ((EC) No 141/2000) has successfully redirected private and public investment towards previously neglected areas through incentives, regulatory obligations and rewards. However, the growth in the number of licensed orphan medicinal products (OMPs) has led to concerns about increased costs. The aims were to investigate the trend in the costs of OMPs to the National Health Service in Wales, to attribute costs of medicines within and outside periods of marketing exclusivity, and estimate the contribution of individual medicines to the overall costs of OMPs.
