Can a learning health system optimise emergency care?Hospitals' emergency departments are intense places, where the speed and efficiency of care is key for good patient outcomes.However, these departments often also deal with patients who have non-critical illnesses, which can restrict the resources available for those who really need them.At the University of Calgary in Canada, Dr Catherine Patocka and Dr Jessalyn Holodinsky are creating a feedback-based learning health system to optimise patient care in emergency departments.
