Bare et al reported the CCR-CARESS score for predicting mortality following surgery for colorectal cancer. This can help to identify a patient with a high short-term mortality rate. The authors are from multiple institutions in Spain.
Patient selection: surgery for colorectal cancer (Stage III in 33%; Stage IV in 10%)
Outcome: 30-day mortality
Parameters:
(1) age in years
(2) COPD
(3) palliative surgery (versus curative)

= SUM(points for all 3 parameters)
Interpretation:
• minimum score: 0
• maximum score: 5
• The higher the score the greater the 30-day mortality.
