Next was a giant step for medical AI as far as testing its performance versus doctors. That came last month with publication of the PaLM foundation model capabilities for the United States Medical Licensing Examination (USMLE),and was also assessed for several other medical question answering challenges, including consumer health questions.
In China, back in 2017, Tsinghua University and the company iFlyTek collaborated to build Xiaoyi (translates to \u201Clittle doctor\u201D) trained on 2 million medical records and 400,000 articles. It was able to achieve a passing score of 456 for the Chinese medical licensing exam for which 360 to 600 is passing, by excelling on memorization and information recall but performing poorly on patient cases. While it attracted media attention, there was (appropriately) no assertion that the AI was ready to take the place of doctors or formally be licensed.
From the above graphic, you can see the PaLM catapulting from 50% accuracy to 67.6%, an absolute jump of 17% (a relative increase of 33%!). Importantly, the parity in medical question answering was demonstrated by 92.6% of doctors saying the MED-PaLM chatbot was right as compared with 92.9% of other doctors being correct. Furthermore, for potential harm of the answers, there was only a small gap: the extent of possible harm was 5.9% for Med-PaLM and 5.7% for clinicians; the likelihood of possible harm was 2.3% and 1.3%, respectively. The authors from Google and Deep Mind concluded: \u201Cthe resulting model, Med-PaLM, performs encouragingly, but remains inferior to clinicians. We show that comprehension, recall of knowledge, and medical reasoning improve with model scale and instruction prompt tuning, suggesting the potential utility of LLMs in medicine.\u201D
I should point out that it\u2019s not exactly a clear or rapid path because there is a paucity of large or even massive medical datasets, and the computing power required to run these models is expensive and not widely available. But the opportunity to get to machine-powered, advanced medical reasoning skills, that would come in handy (an understatement) with so many tasks in medical research (above Figure), and patient care, such as generating high-quality reports and notes, providing clinical decision support for doctors or patients, synthesizing all of a patient\u2019s data from multiple sources, dealing with payors for pre-authorization, and so many routine and often burdensome tasks, is more than alluring.
It\u2019s very early for LLMs/generative AI/foundation models in medicine, but I hope you can see from this overview that there has been substantial progress in answering medical questions\u2014that AI is starting to pass the tests that approach the level of doctors, and it\u2019s no longer just about image interpretation, but starting to incorporate medical reasoning skills. That doesn\u2019t have anything to do with licensing machines to practice medicine, but it\u2019s a reflection that a force is in the works to help clinicians and patients process their multimodal health data for various purposes. The key concept here is augment; I can\u2019t emphasize enough that machine doctors won\u2019t replace clinicians. Ironically, it\u2019s about technology enhancing the quintessential humanity in medicine.
That gets us back to the premise of Deep Medicine, AI has vast transformative potential to improve accuracy and precision of medicine, provide more autonomy for patients, and ultimately achieve the far reaching goal of restoring the patient-doctor relationship that has eroded over many decades. Undoubtedly, over the years ahead, these models, combining massive data and computing power, deep learning on steroids, will find their way to the multitude of medical tasks. I\u2019m optimistic this new era of AI can accelerate the progress that is desperately needed. Stay tuned!
In the midst of the Time War, Daleks and Time Lords bring to bear all the weapons they can find, unleashing untold devastation. But if just one of these infernal devices can provide an advantage - however small - that could mean victory.
A medical device is any device intended to be used for medical purposes. Significant potential for hazards are inherent when using a device for medical purposes and thus medical devices must be proved safe and effective with reasonable assurance before regulating governments allow marketing of the device in their country. As a general rule, as the associated risk of the device increases the amount of testing required to establish safety and efficacy also increases. Further, as associated risk increases the potential benefit to the patient must also increase.
Medical devices vary in both their intended use and indications for use. Examples range from simple, low-risk devices such as tongue depressors, medical thermometers, disposable gloves, and bedpans to complex, high-risk devices that are implanted and sustain life. One example of high-risk devices are those with embedded software such as pacemakers, and which assist in the conduct of medical testing, implants, and prostheses. The design of medical devices constitutes a major segment of the field of biomedical engineering.
The global medical device market was estimated to be between $220 and US$250 billion in 2013.[4] The United States controls 40% of the global market followed by Europe (25%), Japan (15%), and the rest of the world (20%). Although collectively Europe has a larger share, Japan has the second largest country market share. The largest market shares in Europe (in order of market share size) belong to Germany, Italy, France, and the United Kingdom. The rest of the world comprises regions like (in no particular order) Australia, Canada, China, India, and Iran. This article discusses what constitutes a medical device in these different regions and throughout the article these regions will be discussed in order of their global market share.
A global definition for medical device is difficult to establish because there are numerous regulatory bodies worldwide overseeing the marketing of medical devices. Although these bodies often collaborate and discuss the definition in general, there are subtle differences in wording that prevent a global harmonization of the definition of a medical device, thus the appropriate definition of a medical device depends on the region. Often a portion of the definition of a medical device is intended to differentiate between medical devices and drugs, as the regulatory requirements of the two are different. Definitions also often recognize In vitro diagnostics as a subclass of medical devices and establish accessories as medical devices.
Section 201(h) of the Federal Food Drug & Cosmetic (FD&C) Act[5] defines a device as an "instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related article, including a component part, or accessory which is:
which does not achieve its primary intended purposes through chemical action within or on the body of man or other animals and which is not dependent upon being metabolized for the achievement of its primary intended purposes. The term 'device' does not include software functions excluded pursuant to section 520(o)."
According to Article 1 of Council Directive 93/42/EEC,[6] 'medical device' means any "instrument, apparatus, appliance, software, material or other article, whether used alone or in combination, including the software intended by its manufacturer to be used specifically for diagnostic and/or therapeutic purposes and necessary for its proper application, intended by the manufacturer to be used for human beings for the purpose of:
Based on the New Approach, rules that relate to safety and performance of medical devices were harmonised in the EU in the 1990s. The New Approach, defined in a European Council Resolution of May 1985,[7] represents an innovative way of technical harmonisation. It aims to remove technical barriers to trade and dispel the consequent uncertainty for economic operators, to facilitate free movement of goods inside the EU.[citation needed]
The government of each Member State must appoint a competent authority responsible for medical devices.[9] The competent authority (CA) is a body with authority to act on behalf of the member state to ensure that member state government transposes requirements of medical device directives into national law and applies them. The CA reports to the minister of health in the member state. The CA in one Member State has no jurisdiction in any other member state, but exchanges information and tries to reach common positions.
