Summary

Cholesterol screening referral rates vary significantly based on the guidelines used. Different criteria for hypercholesterolemia can lead to a substantial patient load for healthcare systems.

Area of Science:

  • Cardiovascular Health
  • Public Health Screening
  • Clinical Lipidology

Background:

  • Hypercholesterolemia screening is a key public health strategy.
  • Referral patterns are influenced by diagnostic criteria.
  • The impact of screening on healthcare resources requires evaluation.

Purpose of the Study:

  • To assess how different hypercholesterolemia screening criteria affect patient referral rates.
  • To analyze the potential burden on healthcare systems due to cholesterol screening.

Main Methods:

  • Systematic recruitment of an adult population sample (4,404 men, 5,164 women, aged 20-69).
  • Screening for hypercholesterolemia using defined cutoff levels.
  • Analysis of referral patterns based on Lipid Research Clinics, National Cholesterol Education Program (NCEP), and NIH Consensus Conference guidelines.

  • Follow-up cholesterol determination for a subset of referred individuals.

    • Main Results:

    • Referral rates varied widely: 7.3% (men) and 5.8% (women) using ≥265 mg/dL (Lipid Research Clinics), versus 49.2% (men) and 40.2% (women) using ≥200 mg/dL (NCEP).
    • NIH Consensus Conference criteria resulted in 28.0% (men) and 21.8% (women) referrals.
    • Of those initially screened with hypercholesterolemia (≥265 mg/dL), 36% had lower levels upon re-testing.
    • High referral numbers are strongly dependent on chosen cutoff levels and population demographics.

    Conclusions:

    • Population-based cholesterol screening generates a large number of patients requiring follow-up.
    • The choice of screening criteria significantly impacts referral volume and potential healthcare system load.
    • Healthcare communities must be prepared for the resource demands associated with widespread cholesterol screening programs.
