Population-Based Modeling of Cholesterol Lowering in the United States

Status Completed

Clinical Trial Summary

To evaluate the cost-effectiveness of cholesterol-lowering strategies in the United States population. The study used the Coronary Heart Disease (CHD) Policy Model, a state-transition computer simulation model used to obtain forecasts of the public health impact and economic cost of CHD in the United States population.

Clinical Trial Description

BACKGROUND:

The study was part of an Institute-initiated Request for Applications (RFA) titled "Cost-Effective Strategies of Cholesterol-Lowering" released by the NHLBI in 1990. The RFA was stimulated by the controversy concerning costs and cost-effectiveness that followed the 1987 report of the National Cholesterol Education Program (NCEP) Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults. The RFA was intended to support a broad and thorough quantitative exploration of the potential health benefits and costs of cholesterol-lowering from multiple perspectives.

DESIGN NARRATIVE:

The study added to the CHD Policy Model the capability to model the consequences of reductions in LDL cholesterol and increases in HDL/LDL ratios in the United States population. The CHD Policy Model was used for several studies, including: to compare the implications of using alternative epidemiologic studies as the basis for estimating the association between cholesterol levels and CHD risk; to derive cutting points for initiating cholesterol reduction, specific to age, sex, and CHD risk factors, and based on cost-effectiveness criteria; to compare the cost-effectiveness of specific targeted and population-wide strategies for cholesterol reduction; to incorporate the effects of treatments on quality of life, including both adverse effects of cholesterol-lowering drugs and reductions in CHD morbid events; and finally, to perform a cost-effectiveness analysis of cholesterol screening, incorporating costs of screening, effects of measurement error on misclassification of patients, and variations in individual cholesterol levels over time.

The study completion date listed in this record was obtained from the "End Date" entered in the Protocol Registration and Results System (PRS) record. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
