Conclusion CT screening increases healthcare costs compared with no screening; this increase is fully explained by the costs of the CT-screening scans. Overall healthcare costs were higher for the true-positive and false-positive groups than for the control group, also when excluding CT-screening scan costs. Background Low dose computerised tomography (CT) screening for lung cancer can reduce lung cancer mortality but more data on cost-effectiveness are needed before recommendations can be made. Method This study analysed data of participants in the DLCST(figure 1). In Denmark all healthcare costs and services are recorded in public registries. Residents in Denmark have a unique personal identification number and every event in the public healthcare system is linked to this number Healthcare cost data for both the primary and the secondary healthcare sector were retrieved from public registries from randomisation (2004-2006) until September 2011. Results Costs in the randomised groups are presented in figure 2. In the diagnostic groups, costs were 10.57 (95% CI 7.09 to15.75) times higher for the true-positive and 1.67 (95% CI 1.20 to 2.32) times higher for the false-positive group compared with the control group.
