The World Health Organisation Global Code of Practice and migration of health workers from Zimbabwe
Bibliographic record
Abstract
The migration of health workers remains one of the most pressing challenges facing many countries in the global South. This short communication seeks to reignite debate on the effectiveness of the World Health Organisation (WHO) Code as a tool for managing the migration of health workers from the South. While the WHO Code was somewhat effective in reducing the migration of health workers from countries such as Zimbabwe during the first five years of its implementation, demand for health workers in the UK after Brexit and the COVID-19 pandemic has accelerated the rate of migration of health workers from countries facing critical shortages. Clearly, new solutions are needed that strike a balance between the right of health workers in the South to migrate and the right of citizens in the region to a stable supply of health workers.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
