Efficacy of non‐pharmacological interventions to reduce pain in children with sickle cell disease: A systematic review

Abstract

AbstractBackgroundPain 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.MethodsFollowing the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis guidelines, 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 until the age of 21. Both randomized controlled trials (RCTs) and quasi‐experimental designed (QED) studies were considered for inclusion.ResultsTen articles (five RCTs and five QED studies) with 422 participants were included. They investigated cognitive behavioural therapy (CBT) (n = 5), biofeedback (n = 2), massage (n = 1), virtual reality (n = 1) and yoga (n = 1). The majority of the interventions were psychological (n = 7) and were performed in the outpatient clinic (n = 6). CBT and biofeedback significantly reduced frequency and/or intensity of SCD‐related pain in outpatient settings, while virtual reality and yoga significantly reduced pain in inpatient settings. Biofeedback also significantly reduced analgesic use. None of the included articles reported reduced health service use.ConclusionNon‐pharmacological interventions may be effective in reducing pain in paediatric patients with SCD. 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.
