The validity of simplified self-report pain intensity assessment tools in preschool-age children undergoing adenotonsillectomy.

Abstract

To assess the validity of simplified pain scales, including the Simplified Faces Pain Scale (S-FPS) and Simplified Concrete Ordinal Scale (S-COS) in preschool-age children who underwent adenotonsillectomy (T&A) by comparing the values of simplified pain scales with the Faces Pain Scale-Revised (FPS-R) and the Faces, Legs, Activity, Cry, Consolability (FLACC) observational pain scale. The present study consisted of 100 pediatric patients between the ages of 3 and 6years old who had T&A. A two-step pain assessment approach with S-FPS and S-COS and FPS-R and FLACC pain scales was performed with children with the help of their parents or caregivers at the 1st, 6th and 12thhours, and over the 7days after surgery. The mean scores of S-FPS and S-COS were higher than the mean FPS-R scores for each time point for all age groups. The total number of children reporting no pain was higher for FPS-R than S-FPS and S-COS for each age group and the difference was significant for 3-, 4- and 5- year olds. S-FPS, S-COS and FPS-R showed a moderate correlation with FLACC in all age groups, whereas the correlation values were not significantly different between the tests. In the present study, we found that S-FPS and S-COS were valid options for estimating pain in preschool children including 3- and 4-year-olds who underwent T&A.
