Abstract

Background: Postoperative pain is a common and distressing consequence of surgery in children. It can lead to suffering, prolonged recovery, impaired physical functioning, and even chronic pain. Effective postoperative pain management is crucial for improving patient outcomes. However, several factors hinder the accurate assessment and management of pain in children, particularly in low-income countries. This study aims to evaluate the severity of postoperative pain in paediatric patients and identify its predictors. Materials and methods: A longitudinal study was conducted on 235 paediatric surgical patients aged 2 months–7 years in Public Hospitals of Addis Ababa from January to April 2023. The primary outcome, pain severity, was assessed at three different times using a pain assessment tool. Cochran’s q-test was used to compare postoperative pain incidences. The Generalized Estimating Equation was used to determine predictor variables’ effects on pain severity over time. The study demonstrated the direction of association and significance using an AOR with a 95% CI at a P value of 0.05. Result: The incidence of moderate to severe postoperative pain was 36.6% at 12 h, 20% at 24 h, and 10% at 36 h. Patients with preoperative pain and preoperative anxiety were more likely to experience moderate to severe postoperative pain [adjusted odds ratio (AOR)=3.41, CI=1.15, 10.00 and AOR=2.28, CI=1.219, 4.277, respectively). Intraoperative predictors of postoperative pain severity included longer duration of surgery (AOR=6.62, CI=1.90, 23.00) and major surgery (AOR=5.2, CI=2.11, 12.88). Postoperative pain severity was reduced in patients receiving multimodal analgesia (AOR=0.24; CI=0.091, 0.652) and in patients assessed frequently in the postoperative period (AOR=0.09; CI=0.022, 0.393). Conclusion: A significant portion of paediatric surgical patients in this study experienced high levels of postoperative pain, particularly within the first 24 h. The most influential factors affecting pain severity were postoperative pain management strategies and assessment practices.
