We conducted a retrospective cohort study of 103,220 adults with type-2 diabetes receiving care at nine healthcare organizations within the High Value Healthcare Collaborative (HVHC) between October 2012 and September 2014.[6] We measured the association between diabetes control and ambulatory visit frequency.
