Study Overview
Brief Summary
This project assesses the feasibility, appropriateness, and acceptability of a "Commonly Asked Questions after Lung Cancer Screening" (CAQ) informational document that the investigators created, resulting from patient and provider discussion in focus groups and interviews. If effective, the CAQ may be a new tool to help improve patient understanding of LCS results and adherence to follow-up recommendations.
Detailed Description
Barriers to optimal implementation of lung cancer screening (LCS) include low levels of patient knowledge. Patient understanding of LCS results may alleviate distress and improve understanding of recommendations. The investigators developed a "Commonly Asked Questions after LCS" (CAQ) information sheet based on gaps in knowledge identified by patient focus groups and provider interviews. The study objective was to assess CAQ appropriateness and acceptability, and preliminary impact on patient understanding and distress after receiving LCS results.
The investigators conducted a pilot alternating intervention controlled trial of the CAQ. All patients in the University of Washington/Seattle Cancer Care Alliance LCS program who underwent baseline or annual LCS were received a mailing within one week of their scan, either: 1) usual care: a brief form letter with screening results; or 2) usual care plus the CAQ (intervention). The mailing assignment was alternated weekly. Mailed follow-up surveys assessed appropriateness and acceptability of CAQ as well as LCS knowledge in the intervention group.
Primary outcomes include: 1) Ratings of "I understand the results of my most recent LCS CT scan" on a Likert Scale; 2) Correct self-report of next step based on Lung-RADS standardized follow-up; 3) symptoms of distress (measured by IES); as well as 4) measures of acceptability and appropriateness. Secondary outcomes include responses to 6 questions regarding lung cancer screening knowledge.
