Update information

September 2025: This update amalgamates and replaces the NICE antimicrobial prescribing guidelines on community-acquired pneumonia and hospital-acquired pneumonia (both published September 2019), and partially updates and replaces NICE guideline CG191 (published 2014).

Recommendations are marked [2025] if the evidence has been reviewed.

We have also made some changes without an evidence review. These are marked [2019, amended 2025] or [2014, amended 2025].

Recommendations labelled [2019] or [2014] last had an evidence review in 2019 or 2014, respectively.

Minor updates since publication

November 2025: We updated links throughout to the NICE's guidelines on suspected sepsis in people aged 16 or over, suspected sepsis in under 16s and suspected sepsis in people who are or have recently been pregnant, which have replaced the previous NICE guideline on suspected sepsis.
