Considerations for using predictive models that include race as an input variable: the case study of lung cancer screening.
Indiscriminate use of predictive models incorporating race can reinforce biases present in source data and lead to an exacerbation of health disparities. In some countries, such as the United States, there is therefore a push to remove race from prediction models; however, there are still many prediction models that use race as an input. Biomedical informaticists who are given the responsibility of using these predictive models in healthcare environments are likely to be faced with questions like how to deal with race covariates in these models. The authors report that there is a need for a practical framework to facilitate model user thinking on how to incorporate race in their chosen model to avoid inadvertently amplifying disparities. The purpose of this paper is to utilize a case study of lung cancer screening to propose a simple framework to guide model users in approaching race inputs in the predictive models they are attempting to leverage in electronic health records and clinical workflows.

Clinical implications of removing race-corrected pulmonary function tests for African American patients requiring surgery for lung cancer.
This study’s objective was to identify how many hospitals providing lung cancer surgery use race correction in pulmonary function tests (PFTs), examine the association of race correction with predicted lung function, and test the effect of decorrection on surgeons' treatment recommendations. Percent predicted preoperative and postoperative forced expiratory volume in 1 second (FEV1) was calculated for African American patients who underwent lung cancer resection between January 1, 2015, and September 31, 2022, using race-corrected and race-neutral equations for hospitals performing race correction. Randomization of US cardiothoracic surgeons was conducted to receive 1 clinical vignette that differed by the use of Global Lung Function Initiative equations for (1) African American patients (percent predicted postoperative FEV1, 49%), (2) other race or multiracial patients (percent predicted postoperative FEV1, 45%), and (3) race-neutral patients (percent predicted postoperative FEV1, 42%). A total of 515 African American patients (308 [59.8%] female; mean age, 66.2 years) were included in the study. Among these patients, the percent predicted preoperative FEV1 and postoperative FEV1 would have decreased by 9.2% and 7.6%, respectively, if race-neutral equations had been used. A total of 225 surgeons (194 male [87.8%]; mean time in practice, 19.4 years) were successfully randomized and completed the vignette items regarding risk perception and treatment outcomes (76% completion rate). Surgeons randomized to the vignette with African American race-corrected PFTs were more likely to recommend lobectomy (79.2%) compared with surgeons randomized to the other race or multiracial-corrected (61.7%) or race-neutral PFTs (52.8%).

Methods for using race and ethnicity in prediction models for lung cancer screening eligibility.
The purpose of this study was to compare eligibility for lung cancer screening in a representative United States population by refitting the life-years gained from screening-computed tomography (LYFS-CT) model to exclude race and ethnicity versus a counterfactual eligibility method that recalculates life expectancy for racial and ethnic minority individuals utilizing the same covariates but substitutes White race and utilizes the higher predicted life expectancy, preventing historically underserved groups from being penalized. The National Health Interview Survey (NHIS) 2015-2018 included 25,601 individuals aged 50 to 80 years who ever smoked. The study found that removing race and ethnicity from the submodels underestimated lung cancer death risk and all-cause mortality in African American individuals. It also overestimated mortality in Hispanic American and Asian American individuals. As a result, the LYFS-CT NoRace model increased Hispanic American and Asian American eligibility by 108% and 73%, respectively, while decreasing African American eligibility by 39%. Utilizing LYFS-CT with the counterfactual all-cause mortality model better maintained calibration across groups and increased African American eligibility by 13% without decreasing eligibility for Hispanic American and Asian American individuals.

Racial disparities in lung cancer stage of diagnosis among adults living in the southeastern United States.
The purpose of this study was to identify factors contributing to racial disparities in stage of lung cancer stage diagnosis in low-income adults. The researchers identified cases of incident lung cancer from the prospective observational Southern Community Cohort Study by linking them with state cancer registries in 12 southeastern states. A subset of participants who answered psychosocial questions such as those related to racial discrimination experiences were assessed to determine if model predictive power improved. The study identified 1,572 patients with incident lung cancer with available lung cancer stage. Compared with White participants Black participants with lung cancer reflected higher unadjusted odds of distant stage diagnosis. Higher neighborhood area deprivation was related with distant stage diagnosis. No significant differences were found in distant stage disease for Black vs White participants after controlling for individual- and area-level factors, but participants with COPD showed decreased odds of distant stage diagnosis in the primary model.

Evaluation of revised US Preventive Services Task Force lung cancer screening guideline among women and racial/ethnic minority populations.
The purpose of this study was to determine the changes associated with the revised USPSTF guideline for lung cancer screening eligibility among female, Black, and Hispanic populations using a large nationwide survey. The investigators concluded that the revised USPSTF guideline may likely increase lung cancer screening rates for female, Black, and Hispanic populations. However, despite these potential improvements, lung cancer screening inequities may persist without tailored eligibility criteria.

Racial disparities in resection of early stage non-small cell lung cancer: variability among surgeons.
This study examined racial disparities in resection surgery of non-small cell lung cancer (NSCLC). These disparities are well documented. The authors identified 19,624 patients with stage I-II NSCLC 65 years and older from the SEER-Medicare database. They studied patients evaluated by a surgeon within 6 months of diagnosis. Black patients were less likely to undergo resection with resection rates varying among surgeons. Thoracic surgeon specialists were less likely to have any disparities with resection rates.

Elucidating patient-perceived role in "decision-making" among African Americans receiving lung cancer care through a county safety-net system.
The researchers explored patient-perceived role in "decision-making" related to active treatment and palliation among African Americans receiving lung cancer care through a county safety-net system. They found that caregivers and patients expressed a concurrent lack of understanding of their prognosis and outcomes of treatment. Dyads did not discuss their lung cancer experience in terms of decision-making; rather, most articulated their role as following physician guidance.

Racial and geographic disparities in the patterns of care and costs at the end of life for patients with lung cancer in 2007-2010 after the 2006 introduction of bevacizumab.
The authors examined racial/ethnic and geographical disparities in cancer care and costs during the last 6 months of life for lung cancer decedents after the FDA's approval of bevacizumab. They found that there were substantial racial/ethnic and geographic disparities in the types of cancer care and costs in the last 6 months of life among lung cancer decedents, regardless of the length of survival times and hospice care status.
