Policy Points: Medical software has become an increasingly critical component of health care, yet the regulation of these devices is inconsistent and controversial. No studies of medical devices and software assess the impact on patient safety of the FDA's current regulatory safeguards and new legislative changes to those standards. Our analysis quantifies the impact of software problems in regulated medical devices and indicates that current regulations are necessary but not sufficient for ensuring patient safety by identifying and eliminating dangerous defects in software currently on the market. New legislative changes will further deregulate health IT, reducing safeguards that facilitate the reporting and timely recall of flawed medical software that could harm patients.
Medical software has become an increasingly critical component of health care, yet the regulatory landscape for digital health is inconsistent and controversial. To understand which policies might best protect patients, we examined the impact of the US Food and Drug Administration's (FDA's) regulatory safeguards on software-related technologies in recent years and the implications for newly passed legislative changes in regulatory policy.
Using FDA databases, we identified all medical devices that were recalled from 2011 through 2015 primarily because of software defects. We counted all software-related recalls for each FDA risk category and evaluated each high-risk and moderate-risk recall of electronic medical records to determine the manufacturer, device classification, submission type, number of units, and product details.
A total of 627 software devices (1.4 million units) were subject to recalls, with 12 of these devices (190,596 units) subject to the highest-risk recalls. Eleven of the devices recalled as high risk had entered the market through the FDA review process that does not require evidence of safety or effectiveness, and one device was completely exempt from regulatory review. The largest high-risk recall categories were anesthesiology and general hospital, with one each in cardiovascular and neurology. Five electronic medical record systems (9,347 units) were recalled for software defects classified as posing a moderate risk to patient safety.
Software problems in medical devices are not rare and have the potential to negatively influence medical care. Premarket regulation has not captured all the software issues that could harm patients, evidenced by the potentially large number of patients exposed to software products later subject to high-risk and moderate-risk recalls. Provisions of the 21st Century Cures Act that became law in late 2016 will reduce safeguards further. Absent stronger regulations and implementation to create robust risk assessment and adverse event reporting, physicians and their patients are likely to be at risk from medical errors caused by software-related problems in medical devices.
政策要点:医疗软件已成为医疗保健中日益关键的组成部分,然而对这些设备的监管却不一致且存在争议。尚无关于医疗器械和软件的研究评估美国食品药品监督管理局(FDA)当前监管保障措施以及这些标准的新立法变化对患者安全的影响。我们的分析量化了受监管医疗器械中软件问题的影响,并表明现行法规对于通过识别和消除当前市场上软件中的危险缺陷来确保患者安全是必要的,但并不充分。新的立法变化将进一步放松对健康信息技术的监管,减少有助于报告和及时召回可能伤害患者的有缺陷医疗软件的保障措施。
医疗软件已成为医疗保健中日益关键的组成部分,然而数字健康的监管格局却不一致且存在争议。为了解哪些政策可能最能保护患者,我们研究了近年来美国食品药品监督管理局(FDA)的监管保障措施对软件相关技术的影响以及新通过的监管政策立法变化的影响。
利用FDA数据库,我们识别了2011年至2015年期间主要因软件缺陷而被召回的所有医疗器械。我们统计了每个FDA风险类别中与软件相关的所有召回情况,并评估了电子病历的每一次高风险和中风险召回,以确定制造商、设备分类、提交类型、单位数量和产品细节。
共有627个软件设备(140万台)被召回,其中12个设备(190,596台)面临最高风险召回。被召回为高风险的设备中有11个是通过FDA审查程序进入市场的,该程序不需要安全或有效性证据,还有一个设备完全免于监管审查。最大的高风险召回类别是麻醉科和综合医院,心血管科和神经科各有一例。有5个电子病历系统(9,347台)因被归类为对患者安全构成中度风险的软件缺陷而被召回。
医疗器械中的软件问题并不罕见,有可能对医疗护理产生负面影响。上市前监管并未涵盖所有可能伤害患者的软件问题,大量患者接触到后来被进行高风险和中风险召回的软件产品就证明了这一点。2016年末成为法律的《21世纪治愈法案》的条款将进一步减少保障措施。如果没有更强有力的法规和实施措施来建立健全的风险评估和不良事件报告制度,医生及其患者可能会面临医疗器械中软件相关问题导致的医疗差错风险。
