19-LB: Treatment Intensification and Risk of Cardiovascular Events in Insulin-Treated Patients with Type 2 Diabetes: A United Kingdom Retrospective Cohort Study

Using the Clinical Practice Research Datalink, adults diagnosed with T2DM newly initiated with a basal long/intermediate-acting insulin from January 2004 to December 2016 were identified. First change or add on of short or premix insulin and/or OADs was defined as intensification. Patients were categorized into three groups; uncontrolled glycaemia at baseline (≥7% HbA1c) and early (within 1-year) intensifiers, and uncontrolled glycaemia at baseline and delayed (>1-year) intensifiers and uncontrolled-non-intensifiers as a reference groups. A total of n=8,538 patients were included; 32.95% (n=2,813) were uncontrolled-glycaemic-early intensifiers, 28.91% (n=2,468) were uncontrolled glycaemic-delayed intensifiers, and 38.15% (n=3,257) were non-intensifiers. Majority of the early and delayed intensified patients were males (54.60% and 57.41% respectively) and the average age was 62.40years. Non-intensifiers were older (67.72 years) and had a greater number of risk factors. Median baseline HbA1c was 85.90mmol/mol [10.01%] (IQR, 73.9-101.0 mmol/mol; 8.91-11.39%) and 82.50mmol/mol [9.70%] (IQR, 71.60-96.70mmol/mol, 8.70-11.00%) in the early and delayed treatment intensified group respectively. Early treatment intensification within 1-year post basal insulin therapy was linked to 18% (HR CI: 0.65, 1.03), 23% (HR CI: 0.58, 1.02) and 28% (HR CI: 0.58, 0.93) reduction in the risk of HF, MI and stroke respectively. CVE risk was also reduced in the delayed versus non-intensified group. In conclusion, large proportion of patients remain non-intensified post basal insulin despite poor glycemic control, timely intensification in primary care is thus central in minimising CVE complications.
