Calgary Postoperative Pain After Spine Surgery (CAPPS) Score of Yang et al

Description

Yang et al reported the Calgary Postoperative Pain After Spine Surgery (CAPPS) score for identifying a patient at risk for poor postoperative pain control after elective spine surgery. The authors are from the University of Calgary and Icahn School of Medicine at Mount Sinai.

Patient selection: elective spine surgery

Parameters:

(1) age in years

(2) sex

(3) daily opioid use prior to surgery

(4) preoperative NRS neck/back pain (VAS scale from 0 to 10)

(5) depression level, based on PHQ-9, from 0 to 23

(6) number of motion segments (any part of 2 adjacent articulating vertebrae) treated

(7) fusion surgery

Parameter	Finding	Points
age	< 70 years	2
	>= 70 years	0
sex	female	2
	male	0
preoperative opioid use	daily	3
	other	0
preoperative pain	0 to 7	0
	> 7	1
depression	none or mild	0
	moderate or severe (PHQ9 >=10)	1
number of motion segments treated	0 to 2	0
	>= 3	2
fusion surgery	no	0
	yes	2

total score =

= SUM(points for all of the parameters)

Interpreation:

• minimum score" 0

• maximum score: 13

• The higher the score the greater the risk of postoperative pain.

Total Score	Risk of Postoperative Pain	Probability
0 to 4	low	32%
5 or 6	high	63%
9 to 13	extreme risk	85%

Performance:

• The area under the ROC curve is 0.74.
