The impact of substance use on health care utilization, treatment, and outcomes in patients with non-small cell lung cancer.

Background: Mortality from non-small cell lung cancer (NSCLC) has improved with screening and novel treatments. The substance use epidemic has threatened health outcomes in a variety of diseases, but little is known about how it is associated with NSCLC outcomes.

Methods: We performed a retrospective cohort study of 211 patients with NSCLC treated at a safety-net hospital.

Quantifying Downstream Healthcare Utilization in Studies of Genomic Testing.

Objectives: The challenges of understanding how interventions influence follow-up medical care are magnified during genomic testing because few patients have received it to date and because the scope of information it provides is complex and often unexpected. We tested a novel strategy for quantifying downstream healthcare utilization after genomic testing to more comprehensively and efficiently identify related services. We also evaluated the effectiveness of different methods for collecting these data.
