The inquiry’s director, Clint Oellermann, said the WHO had said confidentiality agreements with the stakeholders who provided data prevented them from providing the information to the inquiry. "Without the underlying data the [inquiry] cannot place any significant weight or evidential value on [the report] in arriving at its provisional and final findings."
The inquiry might conduct its own analysis of hospital prices based on the evidence it received, Oellermann said.
The WHO’s senior health policy adviser for Africa, Sarah Barber, said the inquiry could request the information from the participating countries directly.
Lobby group Section 27 said the inquiry’s decision indicated the weight it attached to evidence-based decision-making.
