This study aimed to investigate the impact of shared decision making (SDM) interventions on vaccine uptake, finding that SDM interventions significantly increased vaccine uptake and led to some studies reporting reduced decisional conflict and increased decision confidence.
Background: The interest in shared decision making (SDM) and the use of patient decision aids have increased significantly. Research indicates that this approach has benefits and yet, implementation remains a challenge. To illustrate this development, we focus on vaccine hesitancy which has become a serious public health challenge during the COVID-19 pandemic. Various strategies have been used in healthcare, with limited success, to help patients overcome vaccine hesitancy. It is unclear whether SDM interventions can increase vaccination rates. Aims: Our aim was 2-fold: to provide an overview of SDM and the use of patient decision aids and to determine the effect of SDM interventions on vaccine uptake. Methods: To provide an overview, we drew on our knowledge of the field and summarized the most recent systematic reviews. We examined the impact on vaccine hesitancy by searching for randomized controlled trials (RCTs) of SDM interventions, conducted a meta-analysis and calculated a pooled odds ratio. Additional outcomes were reported in a narrative synthesis. Results: SDM is viewed as the pinnacle of patient-centred care, supported by an ethical imperative and by empirical evidence of benefits. We found 10 RCTs that met our inclusion criteria. SDM interventions significantly increased vaccine uptake compared to control groups (odds ratio = 1.45; 95% confidence interval [1.17,1.80]; p < 0.01). Some RCTs also reported significantly decreased decisional conflict and increased decision confidence. Conclusion: Future health care delivery systems will need to consider how to support the implementation of SDM. Interventions designed to facilitate this approach can represent a helpful, ethically defensible, strategy to increase vaccination rates.
