- Abstract
In its 2021 update of lung cancer screening recommendations, the U.S. Preventive Services Task Force (USPSTF) evaluated strategies that selected people on the basis of risk and emphasized the need for further research on similar studies. This article describes such a study and compares the USPSTF recommendation with an alternative that includes optimal risk thresholds. Visual Abstract. A Cost-Effectiveness Analysis of Risk Model–Based Lung Cancer Screening.: In its 2021 update of lung cancer screening recommendations, the U.S. Preventive Services Task Force (USPSTF) evaluated strategies that selected people on the basis of risk and emphasized the need for further research on similar studies. This article describes such a study and compares the USPSTF recommendation with an alternative that includes optimal risk thresholds. Background: In their 2021 lung cancer screening recommendation update, the U.S. Preventive Services Task Force (USPSTF) evaluated strategies that select people based on their personal lung cancer risk (risk model–based strategies), highlighting the need for further research on the benefits and harms of risk model–based screening. Objective: To evaluate and compare the cost-effectiveness of risk model–based lung cancer screening strategies versus the USPSTF recommendation and to explore optimal risk thresholds. Design: Comparative modeling analysis. Data Sources: National Lung Screening Trial; Surveillance, Epidemiology, and End Results program; U.S. Smoking History Generator. Target Population: 1960 U.S. birth cohort. Time Horizon: 45 years. Perspective: U.S. health care sector. Intervention: Annual low-dose computed tomography in risk model–based strategies that start screening at age 50 or 55 years, stop screening at age 80 years, with 6-year risk thresholds between 0.5% and 2.2% using the PLCOm2012 model. Outcome Measures: Incremental cost-effectiveness ratio (ICER) and cost-effectiveness efficiency frontier connecting strategies with the highest health benefit at a given cost. Results of Base-Case Analysis: Risk model–based screening strategies were more cost-effective than the USPSTF recommendation and exclusively comprised the cost-effectiveness efficiency frontier. Among the strategies on the efficiency frontier, those with a 6-year risk threshold of 1.2% or greater were cost-effective with an ICER less than $100 000 per quality-adjusted life-year (QALY). Specifically, the strategy with a 1.2% risk threshold had an ICER of $94 659 (model range, $72 639 to $156 774), yielding more QALYs for less cost than the USPSTF recommendation, while having a similar level of screening coverage (person ever-screened 21.7% vs. USPSTF's 22.6%). Results of Sensitivity Analyses: Risk model–based strategies were robustly more cost-effective than the 2021 USPSTF recommendation under varying modeling assumptions. Limitation: Risk models were restricted to age, sex, and smoking-related risk predictors. Conclusion: Risk model–based screening is more cost-effective than the USPSTF recommendation, thus warranting further consideration. Primary Funding Source: National Cancer Institute (NCI).
