Richard McManus, Mark Caulfield, Bryan Williams respond to criticisms of the 2011 NICE guideline, arguing that it reflects the reduced costs of generic drugs and new evidence on cardiovascular risk reduction

There is then a detailed search for efficacy and cost effectiveness literature; where required, technical staff do new meta-analyses and economic modelling.5 The process is open with minutes of all group meetings freely available (http://guidance.nice.org.uk/CG/Wave2/14/Development/GDGMinutes for Hypertension), and there is an extensive and exhaustive process of external consultation for each guideline. This includes detailed consideration of the scope and publication of a draft guideline before the guideline emerges in its final form.5 All responses to the consultation are collated and responded to individually, and an audit process ensures that difficult questions are not ignored. Groups such as specialist societies, commercial organisations, research groups with a particular interest, and hospital trusts can register as stakeholders and provide detailed comments.

In the case of hypertension, the update was partial, which meant that the scope was limited to areas where it was …
