Summary

Universal diabetes screening for individuals over 45 in general practice is feasible but yields few cases when age is the only risk factor. Targeting patients with multiple risk factors is more efficient for diabetes detection.

Area of Science:

  • Endocrinology
  • General Practice
  • Public Health

Background:

  • The American Diabetes Association recommends universal screening for diabetes in individuals aged 45 and older.
  • General practices in the UK serve a diverse patient population, necessitating evaluation of screening strategies.

Purpose of the Study:

  • To evaluate the feasibility and yield of universal diabetes screening in general practice for patients over 45.
  • To assess the cardiovascular risk profile of newly diagnosed diabetes patients.

Main Methods:

  • A cross-sectional population study was conducted in a UK general practice.
  • Included were patients aged over 45 not previously diagnosed with diabetes.
  • Fasting blood glucose levels were measured to determine diabetes prevalence.

Main Results:

  • Of 2481 eligible patients, 876 were screened. Diabetes prevalence was 0.2% in age-only risk patients and 2.8% in those with additional risk factors.
  • Screening all patients over 45 required 4 hours/week; targeting those with risk factors halved this time.
  • Newly diagnosed patients frequently had high cardiovascular risk (e.g., hypertension, high cholesterol).

Conclusions:

  • Diabetes screening via fasting blood glucose in general practice is feasible.
  • Screening is low-yield for patients with age as the sole risk factor.
  • Targeted screening of patients with multiple risk factors is more effective for identifying diabetes in this population.
