Variables | Beta | Beta after inflationa | Points |
---|---|---|---|
CSH | 1.05 | 3.84 | 4 |
Age <65 years | 0.66 | 2.44 | 2 |
De novo surgery | 0.47 | 1.71 | 2 |
BMI <20 kg/ m2 | 0.55 | 2 | 2 |
Female sex | 0.27 | 1 | 1 |
BMI, body mass index; CSH, clinically significant haematoma.
Beta coefficient was inflated by dividing the smallest beta coefficient (0.27), and then points were derived by rounding to the nearest integer. The BRUISE-Control He−−ADSS and He++ADSS scores post-operative pain risk score were developed based on the final risk prediction model (He, CSH; A, age; D, de novo surgery; S, slim—BMI <20 kg/m2; and S, sex—female).
