Why It Matters
Less than 5% of Africans who need palliative care receive it, and morphine availability is critically restricted, yet the trial pipeline for affordable pain management is nearly empty.
The Evidence 135 words · target 156
In the burden-versus-investment landscape of African health research, does the distribution of palliative care trials across African nations reveal a systematic research gap? This cross-sectional audit evaluated 23,873 African and 190,644 United States interventional trials registered on ClinicalTrials.gov through April 2026. Investigators computed the Poisson incidence rate as the primary estimand using registry metadata for each nation. Africa hosted 56 palliative care trials (0.2% of its portfolio) compared to 1,126 in the United States, yielding a 0.0-fold disparity in per-population investment. Temporal analysis showed 17.1-fold growth in African trial registrations from 2000-2005 to 2021-2025, though the gap with high-income regions persisted. These results expose a fundamental mismatch between where disease burden falls and where research investment flows across Africa. Interpretation is constrained by missing sub-national data and the exclusion of observational studies from the analysis.
