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

Table 7

Reliability of recalled pain from rest to straight leg raise. The five possible descriptors of recalled pain are converted into three categories: “less pain,” “the same pain,” and “more pain.” The table shows the change in pain from 2nd VRS at rest to 1st VRS by straight passive leg raise.

	Change in pain	Agreement %	Expected agreement %		(95% CI)
All patients; (sOMC 0–28)	2nd VRS at rest to 1st VRS by straight leg raise	73%	36%	0.57	(0.49–0.65)
sOMC 0–7	2nd VRS at rest to 1st VRS by straight leg raise	56%	38%	0.28	(0.16–0.40)
sOMC 8–17	2nd VRS at rest to 1st VRS by straight leg raise	70%	36%	0.52	(0.37–0.68)
sOMC 18–28	2nd VRS at rest to 1st VRS by straight leg raise	76%	36%	0.62	(0.52–0.73)

The consecutive pain ratings are outlined in Figure 2.
