Conclusion

USD
CT screening increases healthcare costs compared with no
screening; this increase is fully explained by the costs of the CTscreening 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 costeffectiveness 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
Figure 1: Design of the Danish Lung Cancer Screening Trial
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.
