[Assessing the number of TB cases using the capture-recapture method with two data sources].
OBJECTIVE
A more accurate assessment of the number of TB cases in Iaşi County using the capture-recapture method.


METHODS
TB patients diagnosed in Iaşi County are included in the Registry of Tuberculosis, and are microbiologically examined. The Registry of Tuberculosis in Iaşi County contains data about the diagnosis and treatment of TB patients that live in this area (notification). The second list includes all the patients smear positive or culture positive for TB. This list will be obtained from the Microbiology Laboratory, from the Clinic of Pulmonary Diseases and the Municipal Hospital of Paşcani.


RESULTS
There are 1,134 notifications, 763 laboratory, 642 overlap and thus 1,255 patients in total. The overlap between the data sources is 51%. The capture-recapture leads to an estimate of 1,348 patients (95% CI: 1,320-1,375). This means that the estimated exhaustive of the notifications is (1,134/1,348) = 84.1% (95% CI: 82.5-85.9%) and the exhaustive of the lab is (763/1,348) = 56.6% (95% CI: 55.5-57.8%)).


CONCLUSIONS
The capture recapture assessment using two data sources estimated a that the notifications are about 84% exhaustive, like WHO estimations (80%).
