Estimating time and transportation costs associated with lung cancer screening and diagnostic lung procedures in Taiwan: a cross-sectional survey in a medical centre

Abstract

ObjectivesEarlier research has evaluated the non-medical costs after lung cancer diagnosis. This study estimated the time costs and transportation costs associated with low-dose CT (LDCT) screening and diagnostic lung procedures in Taiwan.DesignCross-sectional study.SettingA tertiary referral medical centre.Participants and interventionsThe study participants were individuals aged 50–80 years who underwent LDCT screening or diagnostic lung procedures between 2021 and 2022. Participants completed a questionnaire including items on time spent on receiving care, time spent on travel and its cost and time taken off from work by the participant and any accompanying caregiver.Outcome measuresTime costs were valued using the age- and sex-specific average daily wage for employed participants/caregivers. Costs of informal healthcare sector consisted of time cost of the participant, transportation cost and time cost of the caregiver.ResultsA total of 209 participants who underwent LDCT screening (n=84) or non-surgical (n=12) or surgical (n=113) diagnostic lung procedures for the first time were enrolled. Considering the purchasing power parity, the average costs of informal healthcare sector were US$126.4 (95% CI 101.6 to 151.2), US$290.7 (95% CI 106.9 to 474.5) and US$749.8 (95% CI 567.3 to 932.4), respectively, for LDCT screening, non-surgical procedures and surgical procedures.ConclusionsThis study estimated time and transportation costs associated with LDCT screening and diagnostic lung procedures, which could be used for future analysis of cost-effectiveness of lung cancer screening in Taiwan.
