The National Lung Screening Trial established the benefits of low-dose computed tomography for lung cancer screening (LCS) to identify lung cancer at earlier stages. In February 2021, the US Preventive Services Task Force (USPSTF) revised the eligibility recommendations to increase the number of high-risk individuals eligible for LCS and, in effect, expand screening eligibility for vulnerable populations. One strategy for facilitating LCS is to implement targeted screening in geographic areas with the greatest need. In Philadelphia, although neighborhood smoking rates have been defined, it is not known which neighborhoods have the greatest number of people eligible for LCS. In this study, the authors estimate eligibility for LCS within Philadelphia neighborhoods using both previous and current USPSTF guidelines. They used the Public Health Management Corporation's Household Health Survey from 2010, 2012, and 2015 to identify the number of people within ever-smoker groups (current every day, current occasional, and former smokers) by neighborhood in Philadelphia. Using the 2015 National Health Interview Survey (NHIS) Cancer Supplement, they identified the percentages within ever-smoker groups that were LCS eligible using the previous and current USPSTF guidelines. Finally, they applied the percentages eligible for the ever-smoker groups from the NHIS to the numbers in these groups within Philadelphia neighborhoods. They found that the number of Philadelphians eligible for LCS increased from 41,946 to 89,231 after the revised USPSTF guidelines. The current USPSTF guidelines increased eligibility for LCS within all Philadelphia neighborhoods, with the greatest increases in the River Wards planning district. Local providers should use these results to prioritize LCS services within neighborhoods with greatest eligibility.
