Medical technology, or "medtech", encompasses a wide range of
healthcare products and is used to treat diseases and medical conditions affecting humans. Such technologies are intended to improve the quality of healthcare delivered through earlier
diagnosis, less invasive
treatment options and reduction in hospital stays and
rehabilitation times. Recent advances in medical technology have also focused on cost reduction. Medical technology may broadly include
medical devices,
information technology,
biotech, and healthcare services. The impacts of medical technology involve social and ethical issues. For example, physicians can seek objective information from technology rather than read subjective patient reports. A major driver of the sector's growth is the consumerization of medtech. Supported by the widespread availability of smartphones and tablets, providers can reach a large audience at low cost, a trend that stands to be consolidated as wearable technologies spread throughout the market. In the years 2010–2015, venture funding has grown 200%, allowing US$11.7 billion to flow into health tech businesses from over 30,000 investors in the space.
Types of technology Medical technology has evolved into smaller portable devices, for instance, smartphones, touchscreens, tablets, laptops,
digital ink, voice and
face recognition and more. With this technology, innovations like electronic health records (EHR),
health information exchange (HIE),
Nationwide Health Information Network (NwHIN),
personal health records (PHRs),
patient portals,
nanomedicine, genome-based personalized medicine,
Geographical Positioning System (GPS),
radio frequency identification (RFID),
telemedicine,
clinical decision support (CDS), mobile home health care and
cloud computing came to exist.
Medical imaging and
magnetic resonance imaging (MRI) have been long used and proven medical technologies for medical research, patient reviewing, and treatment analyzing. With the advancement of imagining technologies, including the use of faster and more data, higher resolution images, and specialist automation software, the capabilities of medical imaging technology are growing and yielding better results. As the imaging hardware and software evolve this means that patients will need to use less contrasting agents, and also spend less time and money. Further advancement in healthcare is electromagnetic (EM) technology guidance systems, used in medical procedures, allowing real-time visualization and navigation for the placement of medical devices inside the human body. For example, a neuro-navigated catheter is inserted into the brain, or a feeding tube placement in the stomach or small intestine, as demonstrated by the ENvue System. ENvue is an advanced electromagnetic navigation system for enteral feeding tube placement. The system uses a field generator and several EM sensors enabling proper scaling of the display to the patient's body contour, and real-time view of the feeding tube tip location and direction, which helps the medical staff ensure correct placement and avoid placement of the tube in the lungs.
3D printing is another major development in healthcare. It can be used to produce specialized
splints,
prostheses, parts for medical devices and inert implants. The end goal of 3D printing is being able to print out customized replaceable body parts. In the following section, it will explain more about 3D printing in healthcare. New types of technologies also include artificial intelligence and robots.
3D printing 3D printing is the use of specialized machines, software programs and materials to automate the process of building certain objects. It is having a rapid growth in the
prosthesis, medical implants, novel drug formulations and the
bioprinting of human tissues and organs. Risks related to AI include the potential lack of accuracy, and privacy concerns related to the collected data. Delegating decisions to AI systems may also undermine
accountability. Moreover, AI systems sometimes learn undesired behaviors from their training data. For example, an AI trained to detect skin diseases was found to have a strong tendency to classify images containing a ruler as cancerous, since pictures of malignancies typically include a ruler to show the scale.
Applications AI brings many benefits to the healthcare industry. AI helps to detect diseases, administer chronic conditions, deliver health services, and discover the drug. Furthermore, AI has the potential to address important health challenges. In healthcare organizations, AI is able to plan and relocate resources. AI is able to match patients with healthcare providers that meet their needs. AI also helps improve the healthcare experience by using an app to identify patients' anxieties. In medical research, AI helps to analyze and evaluate the patterns and complex data. For instance, AI is important in drug discovery because it can search relevant studies and analyze different kinds of data. In clinical care, AI helps to detect diseases, analyze clinical data, publications, and guidelines. As such, AI aids to find the best treatments for the patients. Other uses of AI in clinical care include
medical imaging,
echocardiography,
screening, and
surgery.
Education Medical
virtual reality provides doctors multiple surgical scenarios that could happen and allows them to practice and prepare themselves for these situations. It also permits medical students a hands-on experience of different procedures without the consequences of making potential mistakes. ORamaVR is one of the leading companies that employ such medical virtual reality technologies to transform medical education (knowledge) and training (skills) to improve patient outcomes, reduce surgical errors and training time and democratize medical education and training.
Robots Modern
robotics have made huge progress and contribution to healthcare. Robots can help doctors in performing variety tasks. Robotics adoption is increasing tremendously in hospitals. The following are different ways to improve healthcare by using robots:
Surgical robots are one of the robotic systems, which allows a surgeon to bend and rotate tissues in a more flexible and efficient way. The system is equipped with a3D magnification vision system that can translate the hand movements of the surgeon to be precise in-order to perform a surgery with minimal incisions. Other robotics systems include the ability to diagnose and treat cancers. Many scientists began working on creating a next-generation robot system to assist the surgeon in performing knee and other bone replacement surgeries.
Consumer-driven healthcare software As part of an ongoing trend towards
consumer-driven healthcare, websites or apps which provide more information on
health care quality and price to help patients choose their providers have grown. As of 2017, the sites with the most number of reviews in descending order included
Healthgrades, Vitals.com, and
RateMDs.com. Yelp, Google, and Facebook also host reviews with a large amount of traffic, although as of 2017 they had fewer medical reviews per doctor. Disputes around online reviews can lead to websites by health professionals alleging defamation. In 2018 Vitals.com was purchased by WebMD which is owned by
Internet Brands.
Patient safety organizations and government programs which have historically assessed quality have made their data more accessible over the internet; notable examples include the HospitalCompare by CMS and the LeapFrog Group's hospitalsafetygrade.org. Patient-oriented software may also help in other ways, including general education and appointments. Disclosure of legal disputes including
medical license complaints or malpractice lawsuits has also been made easier. Every state discloses license status and at least some disciplinary action to the public, but as of 2018, this was not accessible via the internet for a few states. Consumers can look up medical licenses in a national database, DocInfo.org, maintained by the medical licensing organizations Other tools include DocFinder at docfinder.docboard.org The trend to disclosure is controversial and generate significant public debate, particularly about opening up the
National Practitioner Data Bank. In 1996, Massachusetts became the first state to require detailed disclosure of malpractice claims. There is also the case of the Internet, which serves as a repository of information and expert content that can be used to "self-diagnose" instead of going to their doctor. For instance, one need only enumerate symptoms as search parameters at
Google and the
search engine could identify the illness from the list of contents uploaded to the World Wide Web, particularly those provided by expert/medical sources. These advances may eventually have some effect on doctor visits from patients and change the role of the health professionals from "gatekeeper to secondary care to facilitator of information interpretation and decision-making." Apart from basic services provided by Google in
Search, there are also companies such as
WebMD that already offer dedicated symptom-checking apps.
Technology testing All medical equipment introduced commercially must meet both United States and international regulations. The devices are tested on their material, effects on the human body, all components including devices that have other devices included with them, and the mechanical aspects.
The Medical Device User Fee and Modernization Act of 2002 was created to speed up the
FDA's approval process of medical technology by introducing sponsor user fees for a faster review time with predetermined performance targets for review time. In addition, 36 devices and apps were approved by the
FDA in 2016. == Careers ==
