Closing the Testing Gap: Standardization of Comprehensive Biomarker Testing for Metastatic Non–Small-Cell Lung Cancer in a Large Community Oncology Practice

Abstract

PURPOSE: Non–small-cell lung cancer (NSCLC), the leading cause of cancer death in the United States, accounts for 85% of all lung cancer cases. Biomarker testing is an integral part of the care of patients with NSCLC. Despite broad consensus recommendations that all patients with metastatic NSCLC (mNSCLC) undergo comprehensive biomarker testing (comprehensive genomic profiling and PD-L1), testing rates remain suboptimal. METHODS: The primary goal of this project was to apply National Comprehensive Cancer Network (NCCN) guidelines for comprehensive biomarker testing to all new patients with mNSCLC within a large community practice. Plan-Do-Study-Act methodology was used, with cycle 1 focused on provider education and the creation of a mNSCLC initial consult Note (electronic health record template/McKesson iKnowMed G2) and accompanying order set. Staging, template/order set utilization, and comprehensive biomarker testing rates were recorded while workflow processes were monitored. Cycle 2 centered on improved cancer staging, data analytic reporting, auditing, and reeducation. RESULTS: The comprehensive biomarker testing rates increased from a historic rate of 68% to 92.7% during the 1-year intervention period. The template utilization rate was 71% with complete staging (TNM stage and relevant biomarkers) documented in 40%. CONCLUSION: Implementation and standardization of comprehensive biomarker testing of patients with mNSCLC in a large multisite community-based oncology practice is feasible and results in significant improvement in comprehensive biomarker testing and reporting. Establishing reliable and measurable tracking metrics to ensure that these new processes are used and maintained can assist in scaling these processes. Efforts to scale this best practice are planned across the US Oncology Network.
