This literature review has been updated and the following changes made:

The research question, ‘How should potential healthcare infection incidents be assessed?’ has been reworded to say; ‘How should suspected healthcare infection incidents be assessed?

New research question added; How should a healthcare infection incident be ‘closed’, with lessons learned, recorded and disseminated nationally?

A number of recommendations have been rephrased and new recommendations have been added. The grading of existing recommendations has also been changed to reflect the quality of the evidence-base used to inform them.

The Neonatal addendum has been updated to include these changes.
