Background: Tissue Next Generation Sequencing (NGS) testing can identify targetable genetic alterations, and has become an essential component of cancer care. Prolonged turnaround time (TAT) for tissue NGS testing (time from ordering until report arrival) can be a barrier for optimal treatment. Reducing the TAT can significantly aid the decision making process and improve the time to treatment initiation. As a quality improvement project, we explored a strategy to improve the TAT at our safety net hospital. Methods: We studied the TAT of commercial NGS test (FoundationOne CDx) ordered between January and December of 2022 by the oncology service at Bellevue Hospital Center (BHC), an affiliated public hospital. Tissue NGS testing was ordered for solid tumors regardless of tumor origin at the discretion of the provider. During the first half of the year, specimens prepared at BHC lab were manually dropped off at a central location for shipping to Foundation Medicine lab (testing site). The workflow was changed on 7/7/2022 to introduce a courier system to pick up the specimens from pathology lab at BHC. We analyzed the data reported by Foundation Medicine. Results: As of 2/1/2023, all specimens ordered between 1/1/2022 to 12/29/2022 were reported. There were 123 reports, of which 122 were used for the analysis. 1 report was excluded due to mislabelling of the specimen at the testing site that led to significant delay in TAT. The mean TAT of all reported specimens for the year 2022 was 23 days. Introduction of the courier reduced the mean TAT from 25 days to 20 days. After introducing the courier system, the mean time for specimen analysis was similar, but the mean time from specimen ordering to arrival at the testing site was reduced from 14 days to 10 days. Conclusions: The TAT for tissue NGS testing in underserved cancer patients at a safety net hospital can be successfully improved by implementing a courier system. The improvement was achieved regardless of tumor origin or patients’ financial ability to pay and can aid decision making for treatment initiation. This strategy can be adopted by community hospitals without access to on-site NGS testing. We are exploring additional interventions to optimize the workflow to further reduce the TAT.
