Alexander T Janke, MD, MHS

As an emergency medicine physician and health services researcher, I am working to make emergency care safer, high-quality, and lower cost in the U.S. I aim to apply a learning health systems approach, enabled by data science and artificial intelligence, to improve diagnosis in the emergency care setting. My prior work has explored the role of emergency departments in the broader healthcare system, the evolution of acute care utilization patterns over time, and diagnostic quality and value.

My research focuses on diagnostic excellence in emergency medicine, with particular attention to how clinicians and systems manage diagnostic uncertainty in time-sensitive conditions such as pulmonary embolism, acute neurologic presentations, and pediatric abdominal pain. I also study the structural drivers of emergency care quality and value, including emergency department boarding, hospital capacity constraints, and the policy and financing environment in which acute care is delivered. Across these areas, I use national claims data, statewide clinical registries (including the Michigan Emergency Department Improvement Collaborative), and electronic health record data to characterize variation in care and to develop measures and interventions that improve quality at scale.
