The average HbAlc for primary care patients has not changed in recent years and improvements appear unlikely unless clinical practice is modified. The proportion reaching the blood pressure goal of <130/80 mm I-Ig was 23% in 2011, with a two-fold variation between counties. The proportion with blood pressure lower than 140/80 mm Hg was about 61%. The results point to under-treatment and the potential for improvement in all regions. However, there is scope for improvement, as only 46% of diabetic patients under age 80 achieved the LDL cholesterol goal, with county level variations of between 36-58%. On several indicators for stroke and acute myocardial infarction, treatment in line with guidelines and outcomes have improved significantly.
