Neonatal intensive care nurses' assessment of preterm infants' pain and sedation: inter-rater reliability of the neonatal pain, agitation, and sedation scale

Abstract

Background Timely and accurate assessment of pain and sedation in newborns is essential for effective management. Therefore, neonatal pain and sedation assessment remains a key global issue in neonatal intensive care unit (NICU) nursing practice. This study examined the inter-rater reliability of Neonatal Pain Agitation, and Sedation Scale (N-PASS) scores among NICU patients.Methods This prospective observational study assessed agreement among 19 NICU nurses and two independent researchers who completed 190 observations from 82 preterm infants. Each evaluator rated N-PASS independently and blindly. Agreement among three raters-a nurse and two researchers-were analyzed using the intraclass correlation (ICC) and the Fleiss kappa test.Results Agreement levels varied across N-PASS subscales. The ICC and kappa values indicated moderate-to-good reliability for the pain/agitation subscale, whereas the ICC values for the sedation subscale indicated excellent or moderate reliability. Nurses assigned higher mean pain/agitation scores than researchers.Conclusions NICU nurses must improve their N-PASS assessment skills for both pain and sedation. NICU nurse managers should prioritize improving these competencies to improve pain experiences and ensure adequate sedation, given their significant impact on short- and long-term outcomes in preterm infants.
