Completeness and accuracy of electronic recording of paediatric drug-resistant tuberculosis in Cape Town, South Africa

SETTING: Cape Town, South Africa.

OBJECTIVE: To assess the completeness and accuracy of electronic recording of drug-resistant tuberculosis (DR-TB) in children.

DESIGN: Retrospective cohort study. All children aged <15 years treated for DR-TB during 2012 were included, with clinical data collected from routine health services. Matching was performed between clinical data and an extracted data set from an electronic register for DR-TB (EDR.web), and data sources were compared.

RESULTS: Seventy-seven children were identified clinically, of whom only 49 (64%) were found in EDR.web. Most data in EDR.web were complete and accurate, but there were some internal inconsistencies for confirmed TB. Only 4.4% of all EDR.web entries were children.

CONCLUSION: Only two thirds of children clinically treated for DR-TB were recorded in the electronic reporting system, suggesting under-reporting. We also found a lower than expected prevalence of childhood DR-TB, probably suggesting both under-diagnosis and under-recording of DR-TB in children. Clinicians at facility level should be able to access the electronic reporting system, and data transfer between clinical paper-based and electronic sources should be simplified. Cross-linking between electronic registers for drug-susceptible and DR-TB or consolidation of registers could improve the accuracy of recording. Improved recording and reporting of DR-TB in children is needed.
