BackgroundPretreatment invasive nodal staging is paramount for appropriate treatment decisions in non-small cell lung cancer. Despite guidelines recommending when to perform staging, many studies suggest that invasive nodal staging is underused. Attitudes and barriers to guideline-recommended staging are unclear. The National Lung Cancer Roundtable initiated this study to better understand the factors associated with guideline-adherent nodal staging.Research QuestionWhat are the knowledge gaps, attitudes, and beliefs of thoracic surgeons and pulmonologists about invasive nodal staging? What are the barriers to guideline-recommended staging?Study Design And MethodsA web-based survey of a random sample of pulmonologists and thoracic surgeons identified as members of American College of Chest Physicians (CHEST) was conducted in 2019. Survey domains included knowledge of invasive nodal staging guidelines, attitudes and beliefs toward implementation, and perceived barriers to guideline adherence.ResultsAmong 453 responding physicians, 29% were unaware that invasive nodal staging guidelines exist. Among the 320 physicians who knew guidelines exist, attitudes toward the guidelines were favorable, with 91% agreeing guidelines are generalizable and 90% agreeing that recommendations improved their staging and treatment decisions. Approximately 80% responded that guideline recommendations are based on satisfactory levels of scientific evidence, and 50% stated a lack of evidence linking adherence to guidelines to changes in management or better patient outcomes. Nearly 9 in 10 physicians reported at least one barrier to guideline adherence. The most common barriers included patient anxiety associated with treatment delays (62%), difficulty implementing guidelines into routine practice (52%), and time delays of additional testing (51%).InterpretationAmong physicians who responded to our survey, more than one-quarter were unaware of invasive nodal staging guidelines. Attitudes toward guideline recommendations were positive, although 20% reported insufficient evidence to support staging algorithms. Most physicians reported barriers to implementing guidelines. Multilevel interventions are likely needed to increase rates of guideline-recommended invasive nodal staging.Copyright © 2022. Published by Elsevier Inc.
