Software failures were behind 24 percent of all the medical device recalls in 2011, according to data from the U.S. Food and Drug Administration, which said it is gearing up its labs to spend more time analyzing the quality and security of software-based medical instruments and equipment.
The FDA's Office of Science and Engineering Laboratories (OSEL) released the data in its 2011 Annual Report on June 15, amid reports of a compromise of a Web site used to distribute software updates for hospital respirators. The absence of solid architecture and "principled engineering practices" in software development affects a wide range of medical devices, with potentially life-threatening consequences, the Agency said. In response, FDA told Threatpost that it is developing tools to disassemble and test medical device software and locate security problems and weak design.
... "Manufacturers are responsible for identifying risks and hazards associated with medical device software (or) firmware, including risks related to security, and are responsible for putting appropriate mitigations in place to address patient safety," the agency said in an e-mail statement.
Health IT medical devices are the exception, of course. A health IT virtual medical device is always of rock-solid architecture, always uses "principled engineering practices" in software development, and never has life-threatening consequences, of course.
Hence its special regulatory accommodations over non-virtual (tangible) medical devices.
