The Verbal Rating Scale Is Reliable for Assessment of Postoperative Pain in Hip Fracture Patients

Table 8

Reliability of recalled change in pain by straight leg raise at 3-minute interval. The five possible descriptors of recalled pain are converted into three categories: “less pain,” “the same pain,” and “more pain.”

	Change in pain	Agreement %	Expected agreement %		(95% CI)
All patients; (sOMC 0–28)	1st VRS by straight leg raise to 2nd VRS by straight leg raise	68%	50%	0.36	(0.31–0.41)
sOMC 0–7	1st VRS by straight leg raise to 2nd VRS by straight leg raise	43%	37%	0.10	(0.05–0.14)
sOMC 8–17	1st VRS by straight leg raise to 2nd VRS by straight leg raise	70%	54%	0.35	(0.23–0.47)
sOMC 18–28	1st VRS by straight leg raise to 2nd VRS by straight leg raise	70%	52%	0.39	(0.32–0.46)

The consecutive pain ratings are outlined in Figure 2.
