Abstract:
Introduction: multidrug-resistant tuberculosis
(MDR-TB) remains a public health problem
worldwide. In Mozambique, cases of MDR-TB have
increased annually. In 2018, 1,206 cases were
reported, as compared to 943 cases in 2017. The
aim of this study was to assess the surveillance
system for multidrug-resistant tuberculosis in
Maputo City. Methods: an extract from the national
database was considered for a cut-out of the City of
Maputo in the period 2017-2018; the study was
conducted per the guidelines of the Centers for
Disease Control and Prevention, where the
description of the system was carried out, and
evaluation of the attributes. Each attribute was
evaluated according to the established criteria and
parameters. Results: the surveillance system is
based on the collection of data in health centers.
Four hundred and six cases of MDR-TB were
notified, of which 56.8% (231/406) were male and
95.9% (386/406) were ≥15 years. The system was
complex with 4 levels of information transmission.
With regard to flexibility, there was no changing the
variables in the database. Acceptability was good.
The quality of the data was regular with
discrepancy of data of 14.5%. The system was
considered stable as there was no system
interruption. Timeliness with case notification
monthly. The system sensitivity was 72.9%, the
positive predictive value (PPV) was 2.3% and
regarding utility the system has fulfilled its
objectives. Conclusion: the system was not flexible,
the data quality was regular, had moderate
sensitivity and low positive predictive value.
Continuous assessment of data and scale up the
diagnosis for the detection of cases of MDR-TB is
recommended.
