Abstract Insulin‐treated patients with type 2 diabetes require specialist multidisciplinary input to achieve treatment targets. We compared the demographics, achievement of combined NICE targets for HbA1c (≤7.5%), blood pressure (<140/80mmHg) and total cholesterol (<4mmol/L), and insulin use between patients from a local integrated diabetes service with those from a representative UK population. A cross‐sectional evaluation of individual patient data from six randomly‐selected primary care practices in Erewash (Integrated) Diabetes Service was compared with The Health Improvement Network (THIN) UK primary care database. Baseline age (61.5 years vs 65.8 years; p < 0.0001) and duration of insulin use (4.3 vs 6.3 years; p < 0.0001) use were lower in the THIN cohort. Mean HbA1c was similar between the two cohorts but weight, blood pressure, total and LDL cholesterol were significantly lower in the Erewash population compared with THIN. The combined achievement of HbA1c, total cholesterol and blood pressure was 17.5% in the Erewash cohort compared with 9.6% in the THIN cohort (p < 0.0001). There was a higher proportion of insulin users on basal‐bolus than on premix in the Erewash cohort (89.3% vs 10.7%) compared with THIN (59.0% vs 41.1%). The proportion of patients who received concurrent oral glucose‐lowering therapies in the Erewash integrated service was lower, except for SGLT2 inhibitors (2.5% in the Erewash cohort vs 0.5% in THIN; p < 0.0001). This model of an integrated diabetes service appears to confer better achievement for the NICE defined clinical targets compared with the THIN cohort. Further studies are required to investigate the impact of this service model on health economics, patient pathway and patient experience. Copyright © 2017 John Wiley & Sons.
