Evaluation of a National Comprehensive Cancer Network Guidelines–Based Decision Support Tool in Patients With Non–Small Cell Lung Cancer

Key Points Question Is exposure to the National Comprehensive Cancer Center guidelines associated with decreased decisional conflict and increased rates of guideline-concordant care in patients with non–small cell lung cancer? Findings In this nonrandomized clinical trial, exposure to the National Comprehensive Cancer Center guidelines in 76 patients with non–small cell lung cancer was associated with increased smoking cessation counseling and decreased use of adjuvant chemotherapy after resection of early-stage disease. Use of the tool during consultation was also associated with decreased decisional conflict and greater satisfaction with their decision by the patients. Meaning The findings of this study suggest that use of cancer treatment guidelines is not in conflict with shared decision-making; increasing patients’ access to guidelines appears to improve the quality of oncologic care.
