Background: Pain is the clinical hallmark of sickle cell disease (SCD) leading to hospitalization, psychological sequelae and a decreased health-related quality of life. The aim of this systematic literature review is to evaluate the efficacy of non-pharmacological interventions in reducing sickle cell-related pain in children with SCD. Methods: A comprehensive literature search up until October 2022 was performed to identify studies that investigated the efficacy of non-pharmacological interventions on (1) pain frequency and/or intensity, and (2) analgesic and health service use in children with SCD. Randomized controlled (RCTs) trials and quasi-experimental designed (QED) studies that investigated non-pharmacological interventions for pediatric patients with SCD until the age of 21 years were considered for inclusion. Results: Ten articles (5 RCTs and 5 QED studies) with 422 participants were included. They investigated cognitive behavioral therapy (CBT) (n =5), biofeedback (n=2), massage (n=1), virtual reality (n=1) and yoga (n=1). CBT, biofeedback, massage, virtual reality and yoga significantly reduced frequency and/or intensity of SCD-related pain. Biofeedback also significantly reduced analgesic use. Conclusion: Non-pharmacological interventions may be effective in reducing pain in pediatric SCD patients. However, due to the heterogeneity of the included studies a quantitative analysis could not be performed. Awaiting further supporting evidence, healthcare providers should consider implementing these interventions as valuable part of a comprehensive pain management strategy plan to improve the outcome of sickle cell-related pain.
