BackgroundThe Pediatric Critical-Care Observation Tool (P-CPOT) is an adaption of the Critical-Care Pain Observation Tool (CPOT) originally designed to assess pain in nonverbal critically-ill adults.AimThe study validated the P-CPOT in assessing nociceptive procedure pain in pediatric intensive care unit (PICU) children who are unable to verbalize pain.MethodsContent validity was tested using a two-round expert panel review with 8 experts. With a sample of 78 PICU patients, prospective repeated measures were designed to detect the change over time at pre- (T1), during (T2), and post- (T3) for routinely scheduled nociceptive procedures. Each measure was independently completed by two raters using two scales, the P-CPOT and the FLACC (Faces, Legs, Activity, Cry and Consolability).ResultsAll categories had Item-level content validity indices of 0.88 to 1.00. A one-factor structure containing 5 items was established and accounted for 85% variance in P-CPOT scores. Inter-rater reliability was substantial with correlation coefficient of 0.996 and Kappa value of 0.90. A threshold value of 4 resulted in excellent balance between sensitivity (98.6%) and specificity (97.6%). Both tools detected the score changes over time (p = .025). P-CPOT had a larger effect size (Cohen's d = 4.1) as well as a higher score than FLACC at T2 (p = .039). Linear regression revealed that patients being ventilated tended to have a P-CPOT score of 1.1 higher than the FLACC score while controlling for heart rates (p < .001), meaning that P-CPOT is more sensitive than FLACC for detecting pain increase during nociceptive procedures in ventilated patients.ConclusionThe P-CPOT is a valid scale for assessing pain in PICU patients with very good psychometric performance. It is especially adept in detecting pain in ventilated patients.Copyright © 2019 American Society for Pain Management Nursing. Published by Elsevier Inc. All rights reserved.
