June 2022: This guideline updates and replaces NICE guideline CG90 (published October 2009).
We have reviewed the evidence on access to services, service delivery, treatment of new episodes of depression, prevention of relapse, further-line treatment, chronic depression, depression with personality disorder, psychotic depression and patient choice.
Recommendations are marked  if the evidence has been reviewed.
Recommendations that have been deleted, or changed without an evidence review
Some recommendations were deleted from the 2009 guideline. Appendix 1 sets out these recommendations and includes details of replacement recommendations. If there is no replacement recommendation, an explanation for the deletion is given.
For recommendations ending [2009, amended 2022] we have made changes without reviewing the evidence. The reasons for the changes are given in appendix 2.
For recommendations ending , we have not reviewed the evidence. In some cases, minor changes have been made – for example, to update links, or bring the language and style up to date – without changing the intent of the recommendation.
