Silva AG, De Francesco S, Rodrigues M, et al. - In order to determine the reliability of pain assessment in frail and older adults, researchers here examined the test‐retest reliability of (1) the number of painful body sites, (2) pain intensity, and (3) pain extent in institutionalized older adults. They assessed 74 older adults in 2 separate sessions, 2 days to 1 week apart, for pain intensity, number of painful body sites, and pain extent (in pixels) using a vertical pain numeric scale (0 to 10), a body chart divided into 50 body regions, and ImageJ, respectively. Assessing measures of Intraclass correlation coefficients (ICCs), standard error of measurement, and minimal detectable differences, they suggest the vertical pain rating scale and the body chart as reliable for determining pain intensity and number of pain sites, respectively. They observed a wide CI for the ICC for pain area and a high measurement error, both of which compromised its potential clinical importance.
