Prospective Multisite Cohort Study to Evaluate Shared Decision Making Utilization Among Individuals Screened for Lung Cancer

Patient-Provider Discussion About Lung Cancer Screening by Race and Ethnicity: Implications for Equitable Uptake of Lung Cancer Screening

BACKGROUND

Physician-patient discussions regarding lung cancer screening (LCS) are uncommon and its racial and ethnic disparities are under-investigated. We examined the racial and ethnic disparities in the trends and frequency of LCS discussion among the LCS-eligible United States (US) population.

METHODS

We analyzed data from the Health Information National Trends Survey from 2014 to 2020. LCS-eligible individuals were defined as adults aged 55 to 80 years old who have a current or former smoking history. We estimated the trends and frequency of LCS discussions and adjusted the probability of having an LCS discussion by racial and ethnic groups.

RESULTS

Among 2136 LCS-eligible participants (representing 22.7 million US adults), 12.9% (95% CI, 10.9%-15%) reported discussing LCS with their providers in the past year. The frequency of LCS discussion was lowest among non-Hispanic White participants (12.3%, 95% CI, 9.9%-14.7%) compared to other racial and ethnic groups (14.1% in Hispanic to 15.3% in non-Hispanic Black). A significant increase over time was only observed among non-Hispanic Black participants (10.1% in 2014 to 22.1% in 2020; P = .05) and non-Hispanic Whites (8.5% in 2014 to 14% in 2020; P = .02). In adjusted analyses, non-Hispanic Black participants (14.6%, 95% CI, 12.3%-16.7%) had a significantly higher probability of LCS discussion than non-Hispanic Whites (12.1%, 95% CI, 11.4%-12.7%).

CONCLUSION

Patient-provider LCS discussion was uncommon in the LCS-eligible US population. Non-Hispanic Black individuals were more likely to have LCS discussions than other racial and ethnic groups. There is a need for more research to clarify the discordance between LCS discussions and the actual screening uptake in this population.

Assessing Barriers and Facilitators to Lung Cancer Screening: Initial Findings from a Patient Navigation Intervention

Low-dose computed tomography-based lung cancer screening represents a complex clinical undertaking that could require multiple referrals, appointments, and time-intensive procedures. These steps may pose difficulties and raise concerns among patients, particularly minority, under-, and uninsured populations. The authors implemented patient navigation to identify and address these challenges. They conducted a pragmatic randomized controlled trial of telephone-based navigation for lung cancer screening in an integrated, urban safety-net health care system. Following standardized protocols, bilingual (Spanish and English) navigators educated, motivated, and empowered patients to traverse the health system. Navigators made systematic contact with patients, recording standardized call characteristics in a study-specific database. Call type, duration, and content were recorded. Univariable and multivariable multinomial logistic regression was performed to investigate associations between call characteristics and reported barriers. Among 225 patients (mean age 63 years, 46% female, 70% racial/ethnic minority) assigned navigation, a total of 559 barriers to screening were identified during 806 telephone calls. The most common barrier categories were personal (46%), provider (30%), and practical (17%). System (6%) and psychosocial (1%) barriers were described by English-speaking patients, but not by Spanish-speaking patients. Over the course of the lung cancer screening process, provider-related barriers decreased 80% (P = 0.008). The authors conclude that patients undergoing lung cancer screening frequently report personal and health care provider-related barriers to successful participation. Barrier types may differ among patient populations and over the course of the screening process. Further understanding of these concerns may increase screening uptake and adherence.

Patient impressions of the impact of comorbidities on lung cancer screening benefits and harms: A qualitative analysis

OBJECTIVE

To learn about the beliefs and preferences of lung cancer screening (LCS) among patients undergoing LCS decision making. Specifically, we investigated how their comorbidity influences their interest in screening. The goal was to inform shared-decision making discussions around the role of comorbidities and LCS.

METHODS

We recruited English-speaking LCS-eligible individuals with comorbidities from general medicine outpatient clinics at an academic medical center in New York City. The interviewers followed a semi-structured interview guide and all interviews were professionally transcribed. Study investigators independently conducted thematic analysis of de-identified transcripts; after coding, investigators discussed and agreed upon identified themes (Jacobs et al., 1999 [3]). This study was IRB-approved.

RESULTS

We achieved thematic saturation after 15 interviews. We identified the following themes: 1) Comorbidities were perceived as unrelated to LCS decision-making, 2) Lung cancer knowledge is valuable and worth any risks, 3) No matter what the guidelines or my providers say, the LCS decision is up to me.

CONCLUSION/PRACTICE IMPLICATIONS

Implications of these findings are that conversations where providers recommend against LCS may likely require time, patient education, and appreciation of the patient perspective.
