What is AI in healthcare, and how does it work?
By: Dr. Nisarg Patel, ClinicSpots
AI simulates human-like cognitive functions to perform tasks that need analytical, reasoning, problem-solving, and decision-making abilities. AI combines the principal features of data, algorithms, training, and artificial neural networks (ANN).
The structure of the human brain inspires artificial neural networks. AI uses Natural Language Processing (NLP), which leverages applications like chatbots to interpret human language. It is being used across different domains like healthcare, entertainment, finance, and more.
AI in healthcare can help organizations in early diagnosis, treatment, drug discovery, personalized medicine, and improving healthcare administration. For questions about how AI is transforming healthcare, you can ask here at Clinicspots.
What are the benefits of AI and machine learning in healthcare?
AI and machine learning (ML) have the potential to revolutionize healthcare. Some benefits include:
- Improved diagnosis and treatment by analyzing more data. For example, AI-powered image analysis tools are already being used to detect cancer and other diseases in medical images with a high degree of accuracy.
- Personalized medicine: AI-powered drug discovery tools are being used to identify new treatments for diseases resistant to traditional therapies.
- AI and ML help to reduce costs by automating many tasks that are currently performed by humans, like appointments, patient records, etc.
- Improved access to care in rural areas.
- Increased safety by preventing medical errors and employing risk prediction models.
- Aid in drug discovery by screening large numbers of potential drug candidates.
How can AI help in early disease detection?
Methods on how AI can help in early disease detection:
- Analyzing medical images, like X-rays, CT scans, and MRIs. It is also useful to detect signs of disease that may be invisible to the human eye, like lung cancer in CT scans and breast cancer in mammograms.
- Assessing electronic health records to identify patients who are at risk for developing certain diseases.
- Developing predictive models to predict the risk of heart attack, stroke, and Alzheimer’s disease.
- Personalizing treatment to recommend the best course of treatment.
- It can identify diseases earlier, improve patient outcomes, and reduce the cost of healthcare.
Some specific examples of how AI is being used in early disease detection:
- In 2019, Google AI developed a system to detect skin cancer with 95% accuracy.
- In 2020, University of Pennsylvania developed an AI system to detect diabetic retinopathy with 90% accuracy.
- In 2021, University of California, San Francisco developed an AI system that can detect Alzheimer’s disease with 89% accuracy.
Is patient data safe with AI applications in healthcare?
Some potential risks to patient data include:
- Data breaches and cyberattacks.
- Bias in AI algorithms.
- Lack of transparency, making it difficult to assess patient safety and accuracy.
- Loss of control, since AI applications can make decisions about patient care without human oversight.
Safeguards to protect patient data:
- Data encryption to protect from unauthorized access.
- Data anonymization.
- Conducting audits to detect and address bias.
- AI applications should always be subject to human oversight to allow intervention.
- Encourage transparency and accountability.
- Educate patients and healthcare providers about the risks and benefits of AI in healthcare.
- Develop international standards to ensure worldwide protection.
How can AI improve healthcare operations and administrative tasks?
AI can improve healthcare operations and administrative tasks in the following manner:
- Automating routine tasks like appointments, bill processing, etc.
- Improving efficiency and streamlining processes.
- Making predictions about patient outcomes.
- Personalizing care and recommending the best course of treatment.
- Improving communication between healthcare providers and patients by using chatbots.
Are there any ethical concerns with AI in healthcare?
Potential ethical concerns with AI in healthcare include:
- Data privacy and security
- Algorithm bias, like in cases of races or ethnicities
- Lack of transparency
- Loss of patient autonomy
- Job losses for healthcare workers due to automation
- Lack of accessibility to patients in rural areas
Preventative measures:
- Develop clear policies and regulations for the use of AI in healthcare
- Educate healthcare professionals about the ethical concerns of AI
- Involve patients in the development and use of AI
- Support research into the ethical implications of AI in healthcare
Can AI assist in drug discovery and development?
AI can assist in drug discovery and development in the following ways:
- Virtual screening of a large number of potential drug candidates can be done to identify those that are most likely to be effective and safe.
- New drugs can be designed by predicting their structure and properties.
- Target identification for new drug targets, which are the proteins or other molecules that drugs interact with to produce their results, thus identifying the most promising targets.
- Analyzing data from clinical trials to identify patterns and trends which can help to improve the design, speed, and conduct of clinical trials.
- Toxicity prediction of potential drug candidates.
How is AI being used in remote patient monitoring?
- Data analysis from remote patient monitoring (RPM) can be used to identify patterns and trends, like patients at risk of developing complications or who may need additional care.
- Predictive models can forecast the likelihood of a patient developing a disease or condition for early intervention and to prevent complications.
- Develop recommendation engines to design the best course of treatment.
- Automated decision-making, like sending alerts.
- Personalization of treatment to improve the effectiveness.
Are there any AI-powered healthcare applications available to the public?
AI-powered healthcare applications available to the public:
- Symptom checkers: Users can input their symptoms and get recommendations from companies such as Ada Health, Symptomate, and Buoy Health.
- Telemedicine platforms: Virtual doctor-patient consultations and advice, such as Teledoc.
- Apps for mental health: Chatbots and apps to offer therapeutic conversations, mood tracking, etc., such as Woebot.
- Managing medications by reminders, such as Medisafe.
- Detect and monitor disease using radiology and medical images.
- Managing chronic diseases like diabetes and hypertension, such as Omada health.
- Chatbots which provide healthcare information.
Looking forward
The digital era calls for a paradigm shift in the healthcare industry due to novel AI-based techniques. AI now has the potential to transform healthcare through early medical intervention, selective data screening, and personalized patient engagement. Research into various AI-based tools is now paving the way to find better clinical cures for dreaded diseases like cancer, and Alzheimer’s but also helping to manage chronic diseases like diabetes, hypertension, etc. AI is thus helping us to reach new heights in medical research and development, benefiting our future generations.
