Table 2:

Results comparing the addition of a smoking cessation intervention to a low-dose computed tomography screening program for lung cancer versus lung cancer screening program alone

VariableResult
Outcome per 1000 people eligible for smoking cessation intervention*
No. of lung cancer cases prevented12
No. of life-years gained200
Outcome per 1000 people eligible for smoking cessation intervention* discounted at 1.5% per year
Life-years gained130
QALYs gained98
Smoking cessation intervention costs, $2.8 million
Incremental cost of lung cancer treatments, $−600 000
Incremental total direct health care costs, $2.2 million
Incremental cost per QALY gained, $22 200
  • Note: QALY = quality-adjusted life-year.

  • * Based on base-case screening program that assumes annual screening of people aged 55–74 years with 30 pack-year or more smoking history, 60% recruitment rate phased in over 10 years and rescreening adherence rate of 70%; base-case smoking cessation intervention assumes 10 cessation attempts with 2.5% quit rate per attempt at a cost of $622 per attempt.

  • Includes costs of smoking cessation intervention and lung cancer screening, and direct health care costs of treating lung cancer.
