Effectiveness of interventions used to prepare preschool children and their parents for day surgery: A systematic review and meta-analysis of randomised controlled trials

Background To evaluate how effective preparatory interventions for paediatric day surgery are at reducing parents' anxiety and stress and children's pain and fear. Methods A systematic review was conducted according to Joanna Briggs Institute (JBI) guidelines and reported using the PRISMA 2020 checklist. PubMed, CINAHL (EBSCO), Scopus, Medic and Web of Science were screened for original research published up until December 2020, while Mednar and EBSCO Open Dissertations were used to identify any relevant grey literature. The methodological quality and risks of bias were evaluated according to JBI guidelines by two authors. The eligibility criteria were parents of a preschool (2- to 6-year-old) child going through day surgery with preparatory interventions, outcomes measured anxiety, stress (parent), fear and pain (child), and randomised controlled trial (RCT). Results Two thousand and three hundred and fourteen RCTs were screened. Fifteen studies (including 1514 participants) were chosen for narrative synthesis of parental anxiety and stress and children's fear and pain. Nine studies underwent a meta-analysis of parental anxiety (n = 970). The interventions were categorised as functional, informative or a combination of both. Four interventions reduced parents' anxiety while two significantly alleviated children's postoperative pain. The interventions found to be effective combined various ways of providing information. The meta-analysis did reveal a statistically significant impact on parents' anxiety (SMD =0.22, 95% Cl [0.03, 0.41], z = 2.28, p = .023). None of the studies dealt with parental stress or fear in children. Conclusions The studied interventions used various preparatory approaches, some of which were effective at reducing parental anxiety. More RCT studies are needed to find the most effective methods for preparing parents and their children for day surgery. Relevance to Clinical Practice Preparation for day surgery through appropriate interventions can reduce anxiety among parents and postoperative pain in children.
