Start4All — Cameroon Country Data Management
BCHPR · 7-country programme with LSTM + Stop TB Partnership · 2023 – present
End-to-end Cameroon data operations for Start4All — a 7-country TB intervention programme evaluating near-POC molecular diagnostics and sputum pooling. Evidence fed the WHO 9 March 2026 recommendations; LSTM's 27 February 2026 commentary explicitly cited Start4All.
Highlights
- Data workflows across screening and treatment event forms with dynamic data-dictionary-driven recoding (no hard-coded value→label maps).
- Calculated delay metrics: screening → diagnostic → treatment initiation timelines.
- Multi-level TB outcome classification (cure / failure / lost-to-follow-up) with competing-event logic over 6-month follow-up.
- Prioritisation flagging surfacing high-value data-entry errors for enumerator QA.
- Participant-level activity scoring and data quality workflows for enumerator performance management.
- Country evidence stream later cited in WHO recommendations on sputum pooling and near-POC TB tests.
