Cardiac Screening Cost-Effectiveness Model (Population-Level)

  • Population size (N)
  • Prevalence of high-risk individuals (%)
  • Screening test sensitivity (%)
  • Screening test specificity (%)
  • Screening test cost per person
  • Confirmatory test cost per positive screen
  • Annual treatment cost per true positive
  • Treatment duration / time horizon (years)
  • Annual baseline event risk in high-risk group (% per year)
  • Relative risk reduction with treatment (%)
  • Acute care cost per cardiovascular event
  • QALY loss per event
  • Discount rate (% per year)
  • Willingness-to-pay threshold per QALY
  • Cardiac Screening Cost-Effectiveness Model (Population-Level): Explanation and Clinical Context
    This calculator implements a population-level cost-effectiveness framework to evaluate cardiac screening programs that identify high-risk individuals and initiate preventive therapy. Users input epidemiologic parameters, screening performance, and cost/QALY data to estimate ICER, QALY gains, and total costs. The model applies reference-case conventions and allows rapid scenario testing for cardiac risk screening strategies.
