How we made the decision

We check our guidelines regularly to ensure they remain up to date. We based the decision on surveillance 6 years after the publication of coexisting severe mental illness (psychosis) and substance misuse: assessment and management in healthcare settings (2011) NICE guideline CG120.

For details of the process and update decisions that are available, see ensuring that published guidelines are current and accurate in 'Developing NICE guidelines: the manual'.

Previous surveillance update decisions for the guideline are on our website.

New evidence

We found 1 new study in a search for systematic reviews published between 12 December 2014 and 18 July 2016. We also considered 7 additional studies identified by members of the guideline committee who originally worked on this guideline.

Evidence identified in previous surveillance 2 years and 4 years after publication of the guideline was also considered. This included 5 studies identified by the Evidence Update and 47 studies identified by the 4-year surveillance review.

From all sources, 60 studies were considered to be relevant to the guideline.

We also checked for relevant ongoing research, which will be evaluated again at the next surveillance review of the guideline.

See appendix A: summary of new evidence from surveillance and references for all new evidence considered.

Views of topic experts

We considered the views of topic experts, including those who helped to develop the guideline and other correspondence we have received since the publication of the guideline.

Views of stakeholders

Stakeholders are consulted only if we decide not to update the guideline following checks at 4 and 8 years after publication. Because this was a 6-year surveillance review, and the decision was not to update, we did not consult on the decision.

See ensuring that published guidelines are current and accurate in 'Developing NICE guidelines: the manual' for more details on our consultation processes.
