A Government Accountability Office (GAO) report shows that the US Food and Drug Administration (FDA) has not met its statutory requirement for inspections every 2 years of US manufacturers of such high-risk medical devices as pacemakers.
In the report, presented at a January 29 hearing before the House Committee on Energy and Commerce's Subcommittee on Oversight and Investigations, the GAO said the FDA estimates that it inspects manufacturers of high-risk devices every 3 years and those producing medium-risk devices (such as hearing aids) every 5 years. And while there is no comparable requirement for inspecting plants outside the United States, the FDA estimated that it inspects foreign manufacturers of high-risk devices every 6 years and those making medium-risk devices every 27 years (http://www.gao.gov/new.items/d08428t.pdf).
