Data quality assessment of a South African electronic registry for drug-resistant TB, 2015-2016.

Setting: Assessment of bedaquiline roll-out in South Africa requires accurate patient data in EDRWeb, a national case-based rifampicin-resistant TB (RR-TB) surveillance register.

Objective: To ensure EDRWeb data reflect programmatic DR-TB source data, we implemented a data quality improvement initiative.

Design: We conducted data quality assessments of EDRWeb data compared to paper patient folders at two South African RR-TB treatment facilities in 2015 and 2016.
