Objectives. We examined the relationship between continuityof care and diabetes control.
Methods. We analyzed data on 1400 adults with diabetes who tookpart in the Third National Health and Nutrition ExaminationSurvey. We examined the relationship of continuity of care withglycemic, blood pressure, and lipid control.
Results. Continuity of care was associated with both acceptableand optimal levels of glycemic control. Continuity was not associatedwith blood pressure or lipid control. There was no differencebetween having a usual site but no usual provider and havinga usual provider in any of the investigated outcomes.
Conclusions. Continuity of care is associated with better glycemiccontrol among people with diabetes. Our results do not supporta benefit of having a usual provider above having a usual siteof care.
