China’s National Medical Products Administration (NMPA) has issued a guidance for human factors engineering (HFE) of medical devices, a document that by some accounts aligns fairly well with guidance from the U.S. FDA. However, Yvonne Limpens, manager of the human factors program at Emergo by UL, said NMPA may push for domestic HFE testing on imported devices because of a perception that device usability may be different in China than in other nations, thus adding to the cost of doing business in the world’s second most populous nation.
