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
