qCanadian tuberculosis surveillance includes chest X-ray screening of permanent resident applicants. This study was designed to assess such screening from a cost minimization perspective (cost per case of active TB detected and treated) and a cost effectiveness perspective (incremental cost per case prevented). The two strategies compared were no screening program (passive detection of active pulmonary TB) and screening for active and inactive pulmonary TB. The cost per case of active TB via passive detection was estimated to be $7675.87. Between 1 June 1996 and 1 June 1997, 12898 applicants underwent screening chest X-rays at the Montreal Chest Institute, among whom 16 cases of active TB were detected and treated and 322 cases of inactive TB were detected. The cost per case detected and treated through screening was $31419.33. 56% of those with inactive TB were prescribed preventive treatment, and 76% of these individuals were compliant. The incremental cost per case prevented through the screening program was calculated to be $16376.09. Thus from a cost minimization perspective, no screening was preferable to screening, but from a cost effectiveness perspective, when the benefit of cases prevented through screening was considered, the screening program appeared to be worthwhile in comparison to other health interventions.q --aquot;Canadian tuberculosis surveillance includes chest X-ray screening of permanent resident applicants.
