Delays in access to healthcare and extended wait times have been found to be associated with multiple consequences including, but not limited: to poorer health outcomes, financial burden from seeking non-network care, higher rates of appointment no-shows, unnecessary emergency department visits, frustration, inconvenience, and dissatisfaction with the healthcare system. While preventing delays and reducing wait times are particularly critical for many health services, to improve or optimize access by any method requires understanding what defines bad access and how its consequences are quantified. This project focus area aims to develop a methodology to better understand, define and quantify access to care and its effects on cost, flow, and patient health.
