Evaluation of Multi Drug Resistant Tuberculosis Surveillance System, Yemen

Avaliação do Sistema de Vigilância da Tuberculose Drogarresistente, Brasil, 2013-2017*

“…In the Yemen, a study conducted in sentinel units evaluated DRTB-SS as having com moderate simplicity. 18 In the United States, a pilot instrument prepared to obtain basic information on DRTB cases was considered to be simple. 19 In comparison with the results of these two studies, DRTB-SS can be considered to have been implemented throughout Brazil, having consolidated workflows and activities which, to a certain extent, justify its complexity.…”

“…Low DRTB-SS sensitivity has already been documented in other studies, highlighting the need to improve access to diagnosis and treatment. 18 Moderate notification timeliness and low validation timeliness indicate that these processes can be carried out in a shorter space of time, although there is no standard timeliness for these items. Untimely validation, together with other factors, such as the time taken to make laboratory test results available, 23 can delay the start of treatment, contributing to dissemination of resistant bacilli and, consequently, worsening of the patient's condition.…”

“…[15][16] Based on the Venn diagram, we identified the number of DRTB cases on the SITETB system (S1), the number of cases on the SINAN system closed as DRTB cases (S2) and the number of cases on both systems (A). 17 The estimated total number of DRTB cases (Ne) was calculated using the Chapman formula, 18 where Ne=((S1+1)(S2+1)/A+1)-1 Taking the estimated number of cases, the proportion of cases notified by the SITETB system was then calculated. d) Average proportion (%) of 'I agree totally' and 'I agree partially' answers to the following items of the satisfaction survey:…”
