Although advances in diagnostic imaging have improved early detection, significant inequities persist in the period following a confirmed diagnosis, where delays in care can lead to disease progression and poor survival outcomes. The theoretical framework is the Health Belief Model (HBM) which explains health behavior through perceptions of susceptibility, severity, benefits, and barriers to action. The overall study aim is to quantify the differences in average time to first follow-up appointment, staging, and referral post CT-diagnosed lung cancer between African American males and White males. The global research question is: What are the differences in average time to first follow-up appointment, staging, and referral following a CT-based lung cancer diagnosis between African American males and White males? The null hypothesis is: There are no difference in average time to first follow-up appointment, staging, or referral following a CT-based lung cancer diagnosis between African American males and White males. The significance of the study lies in its focus on a population that experiences the highest lung cancer mortality yet remains underrepresented in post-diagnosis research. By examining care after diagnosis rather than screening participation, this study addresses a critical gap in the literature and contributes to evidence-based strategies for improving equity in care coordination, timeliness, and treatment initiation among African American males. The study design is a retrospective secondary analysis using electronic medical record data from the TriNetX Database comparing average time to first follow-up appointment, staging, and referral post CT-based lung cancer diagnosis between African American males and White males.
