Since entering medical school, Gemma’s curiosity in the multifactorial approach to problem solving has led her to the topic of shared decision making (SDM), a collaborative approach by which clinicians, patients and caregiver(s) engage in a partnership to synthesize the best-available medical evidence about the available options with the patient’s values, needs and preferences to arrive at the optimal decision for the patient. Within the Gill Lab, Gemma is working to summarize recent implementations of SDM in pediatric inpatient settings and describe the effect of SDM interventions on parent-reported and clinical outcomes.
