    Effects of removing reimbursement restrictions on targeted therapy accessibility for non-small cell lung cancer treatment in Taiwan: an interrupted time series study by Jason C Hsu, Chen-Fang Wei, Szu-Chun Yang

    Published 2019-03-01
    “…Gefitinib was initially approved and reimbursed as a third-line therapy for patients with advanced NSCLC by the Taiwan National Health Insurance (NHI) in 2004; subsequently it became a second-line therapy (in 2007) and further a first-line therapy (in 2011) for patients with epidermal growth factor receptor mutation-positive advanced NSCLC. Another targeted therapy, erlotinib, was initially approved as a third-line therapy in 2007, and it became a second-line therapy in 2008.Objectives This study is aimed towards an exploration of the impacts of the Taiwan NHI reimbursement policies (removing reimbursement restrictions) related to accessibility of targeted therapies.Setting We retrieved 2004–2013 claims data for all patients with lung cancer diagnoses from the NHI Research Database.Design and outcome measures Using an interrupted time series design and segmented regression, we estimated changes in the monthly prescribing rate by patient number and market shares by cost following each modification of the reimbursement policy for gefitinib and erlotinib for NSCLC treatment.Results Totally 92 220 patients with NSCLC were identified. …”
