While lifestyle accounts for up to 3/4 of healthcare costs, most people do not find exercise fun. Some have tried numerous diet and exercise programs with the primary goal of weight loss, only to fail and become discouraged, resulting in worse health outcomes over time. In this paper, we explore crucial elements in consumer engagement that can lead to improved health outcomes. We deploy data mining algorithms to understand the impacts of various interventions, such as social network, visual dashboard, event processing, games and challenges, on health outcomes using data obtained from a clinical trial. We explain what worked, what did not work, and why. More importantly, we describe salient attributes of social health games that are crucial in both consumer engagement and health outcomes.

Dr. Jin S. Hahn is Professor of Neurology and Pediatrics at Stanford. He attended Harvard College and Medical School, and then completed pediatrics and neurology residencies at Boston Children’s Hospital.

Dr. Hahn’s clinical research interests include congenital brain malformations, neonatal seizures, neonatal hypoxic-ischemic brain injury, and demyelinating disorders of childhood, such as acute disseminated encephalomyelitis and multiple sclerosis. Recently he has become increasingly interested in fetal neurology. With the perinatologists and neonatologists, he plays a key role in the Center for Comprehensive Fetal Health & Maternal and Family Care. Through this center he runs a prenatal neurology consult program.

Dr. Hahn is also a Silicon Valley “techie.” He has been a key member of the Clinical Informatics Program at Lucile Packard Children’s Hospital, and helped implement its Electronic Health Record System and Clinical Decision Support System. He has also developed on-line resources for neurologists, patients, and families for sharing knowledge and building a community.
