Fewer than Two-Thirds of Veterans Receive Timely Lung Cancer Screening Follow-Up


BACKGROUND:
Lung cancer remains the leading cause of cancer mortality, but research shows that yearly lung cancer screening (LCS) achieves a 20% relative reduction in mortality. Although the U.S. Preventive Services Task Force has recommended LCS for high-risk individuals since 2013, there has been limited evidence on follow-up after initial LCS in real-world settings. This retrospective cohort study sought to determine adherence to recommended next steps (i.e., annual screening or evaluation of screen-detected findings) in a national cohort of Veterans screened for lung cancer – and to identify factors associated with delayed or absent follow-up. Using VA data, investigators identified 28,294 Veterans ages 55-80 with >30 pack per year smoking history and who either currently smoked or quit <15 years ago – and who underwent initial LCS in any VA facility from 1/1/2015 through 11/30/2019. The primary outcome was receipt of the recommended next step following index LCS according to Lung-RADS assessment categories for LCS (i.e., incomplete, negative, benign, suspicious, very suspicious). The covariates examined included patient demographics, priority status, healthcare use, comorbidities, and distance to a VA healthcare facility. Random chart reviews also were conducted.

FINDINGS:

  • Less than two-thirds of Veterans received timely recommended follow-up after an initial lung cancer screening, with higher risk of delayed or absent follow-up among marginalized populations that have long experienced disparities in lung cancer outcomes. Of the 28,294 Veterans in this study, 63% underwent recommended follow-up, while 29% received delayed (13%) or no (16%) follow-up.
  • Veterans with higher-risk findings (higher Lung-RADS category) and those in high-volume or academic centers were more likely to receive timely follow-up. Black Veterans, Veterans with mental health disorders or lower income were more likely to have delayed or absent follow-up.
  • Most Veterans (21,557, 76%) had low-risk findings on index LCS (Lung-RADS 1 or 2; negative or benign appearance), while 4,001 (14%) had indeterminate results (Lung-RADS 3; probably benign), and 2,736 (10%) had suspicious findings (Lung-RADS 4; suspicious or very suspicious).

IMPLICATIONS:

  • To optimize the mortality benefit of lung cancer screening, further work must be done to improve adherence, overall, and especially among marginalized populations.

LIMITATIONS:

  • Investigators were unable to capture care received outside of VA or Medicare.
  • Investigators could not measure patient-centered outcomes (i.e., lung cancer diagnoses and mortality), so focused on adherence to screening which is a key factor in lung cancer mortality.

What are HSR&D Publication Briefs?

HSR&D requires notification by HSR&D-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR&D and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR&D based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR&D published articles. Visit the HSR&D citations database for a complete listing of HSR&D articles and presentations.
