Shared Decision Making in Pediatrics: A Systematic Review and Meta-analysis

BACKGROUND: Little is known about the impact of interventions to support shared decision making (SDM) with pediatric patients. OBJECTIVES: To summarize the efficacy of SDM interventions in pediatrics on patient-centered outcomes. DATA SOURCES: We searched Ovid Medline, Ovid Embase, Ovid Cochrane Library, Web of Science, Scopus, and Ovid PsycInfo from database inception to December 30, 2013, and performed an environmental scan. STUDY ELIGIBILITY CRITERIA: We included interventions designed to engage pediatric patients, parents, or both in a medical decision, regardless of study design or reported outcomes. STUDY APPRAISAL AND SYNTHESIS METHODS: We reviewed all studies in duplicate for inclusion, data extraction, and risk of bias assessment. Meta-analysis was performed on 3 outcomes: knowledge, decisional conflict, and satisfaction. RESULTS: Sixty-one citations describing 54 interventions met eligibility criteria. Fifteen studies reported outcomes such that they were eligible for inclusion in meta-analysis. Heterogeneity across studies was high. Meta-analysis revealed SDM interventions significantly improved knowledge (standardized mean difference [SMD] 1.21, 95% confidence interval [CI] 0.26 to 2.17, P =.01) and reduced decisional conflict (SMD -1.20, 95% CI -2.01 to -0.40, P = .003). Interventions showed a nonsignificant trend toward increased satisfaction (SMD 0.37, 95% CI -0.04 to 0.78, P = .08). LIMITATIONS: Included studies were heterogeneous in nature, including their conceptions of SDM. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: A limited evidence base suggests that pediatric SDM interventions improve knowledge and decisional conflict, but their impact on other outcomes is unclear.
