Description

Cross et al reported the BRRISC score to predict risk of recurrence in a patient being treated for cellulitis. This can help to identify a patient who may benefit from more aggressive management.  The authors are from the University of Sussex and University of Oxford in England.

 


Patient selection: adult with cellulitis

 

Parameters:

(1) age in years

(2) heart rate in beats per minute

(3) blood urea in mmol/L

(4) platelet count in 10^9/L

(5) serum albumin in g/L

(6) history of previous cellulitis

(7) venous insufficiency

(8) liver disease
