This in turn may have led to the increased tracing rate of suspects.
The five rates related to notification of university student TB suspects were referral rate, referral arrival rate, tracing rate, tracing arrival rate and total arrival rate.
Moreover, a slightly higher first level contact tracing rate will not alter the dynamics significantly (row 1, Table 2).
Before the intervention, there were no significant differences in referral rate, referral arrival rate, tracing rate, tracing arrival rate, and total arrival rate between the control group and the intervention group.
Only when the first level contact tracing rate is drastically increased (more than tripled in row 2, Table 2), will the solution go to disease free.
Advantages of this study include the representativeness of the participants (Wadsworth et al, in press) and a high tracing rate of mammograms (91%).
We successfully obtained copies of mammograms for 1319 of the 1471 women who gave consent (90% tracing rate), the large majority (1249 (95%)) from NHS breast screening centres.
We successfully obtained copies of mammograms for 1,319 of the 1,471 women who gave consent (90% tracing rate), the large majority [1,249 (95%)] from NHS breast screening centers.
Moreover, drastic increase (by more than three-fold) in the first level contact tracing rate is need for the system to become disease free.
The referral rate, the referral arrival rate, tracing rate and total arrival rate increased to 97.2%, 83.1%, 95.0%, and 93.2% respectively, while the rates remained between 40% and 50% in the control group.
