Cardiovascular risk factor control in British adults with diabetes mellitus: Retrospective cohort study

Area of Science:

• Cardiology
• Endocrinology
• Public Health

Background:

• Diabetes mellitus is a major risk factor for cardiovascular disease.
• Effective management of cardiovascular risk factors is crucial for preventing complications in diabetic patients.
• Primary care plays a vital role in managing diabetes and its associated risks.

Purpose of the Study:

• To assess the control of key cardiovascular risk factors in adults with diabetes mellitus within the first year of diagnosis.
• To identify the proportion of patients achieving targets for HbA1c, systolic blood pressure (SBP), LDL cholesterol, and smoking status.
• To evaluate the need for enhanced quality improvement strategies in diabetes care.

Main Methods:

• Utilized electronic medical records from the UK Health Improvement Network Database (2003-2015).
• Analyzed data from 292,170 British adults diagnosed with diabetes mellitus.
• Examined cardiovascular risk factor control at a median of 354 days post-diagnosis, considering glycemic control (HbA1c), blood pressure, LDL cholesterol, and smoking status.

Main Results:

• Overall control of cardiovascular risk factors was suboptimal, with only 14.7% meeting all targets (HbA1c <7%, SBP <140 mmHg, LDL ≤1.8 mmol/L or on statin, non-smoker).
• Specific control rates included: HbA1c <7% (52.0%), SBP <140 mmHg (53.1%), LDL ≤1.8 mmol/L or on statin (90.4%), and non-smokers (86.0%).
• Despite 71.4% receiving antihypertensive agents, only 53.1% achieved SBP <140 mmHg, highlighting a gap in blood pressure management.

Conclusions:

• There is a significant need for improved quality of care targeting multiple cardiovascular risk factors in individuals with diabetes.
• Current management strategies may not be sufficiently effective in achieving comprehensive risk factor control.
• Future interventions should focus on a holistic approach to managing atherosclerotic risk factors beyond glycemic control alone.
