CAP Flashcards by Katharine Pates

Bob presents to primary care with symptoms of a LRTI. A point of care CRP is done, which is 18. Should he be given abx?

No - NICE guideline. For pts presenting in primary care with symptoms of LRTI, consider point of care CRP if diagnosis of pneumonia not made and not clear whether abx should be given.
- <20 = no
- 20-100 = consider delayed prescription (they can cash if symptoms worsen)
- >100 = give abx
