You will also explore relevant jobs and online courses that can help you get started using AI for healthcare purposes today.
Types of AI in Healthcare
Artificial Intelligence is a general term that encompasses many different but related processes. Some of the most common forms of AI used within healthcare include:
Machine Learning
Machine learning (ML) is the process of training algorithms using data sets, such as health records, to create models capable of performing such tasks as categorizing information or predicting outcomes. For example, ML can be used to analyze medical images, such as X-rays or MRI scans, and detect abnormalities or diagnose conditions.
Deep Learning
Deep learning is a subset of machine learning that involves greater volumes of data, training times, and layers of ML algorithms to produce neural networks capable of more complex tasks. For example, deep learning can be used to generate synthetic data, such as synthetic medical images, that can augment existing data and improve the performance of ML models.
Natural Language Processing
Natural language processing (NLP) is the use of ML to understand human language, whether it be verbal or written. In healthcare, NLP can be used to interpret documentation, notes, reports, and published research. For example, NLP can be used to extract relevant information from electronic health records (EHRs), such as patient symptoms, medications, or lab results, and use them to support clinical decision making.
Robotic Process Automation
Robotic process automation (RPA) is the use of AI in computer programs to automate administrative and clinical workflows. These programs can mimic human actions, such as clicking, typing, or copying, and perform them faster and more accurately. For example, RPA can be used to automate tasks such as scheduling appointments, billing, or claims processing, and reduce the burden on healthcare staff.
Applications of AI in Healthcare
As artificial intelligence becomes more widely adopted, so too does the number of ways the technology is being used across the health sector. Some of the most prominent applications of AI in healthcare include:
Clinical AI Tools
Clinical AI tools are those that directly assist with patient care, such as:
- Predicting health trajectories of patients, such as their risk of developing certain diseases, their response to treatments, or their likelihood of survival.
- Recommending treatments, such as drugs, dosages, or therapies, based on the patient’s condition, preferences, and medical history.
- Guiding surgical care, such as using robotic surgical equipment outfitted with AI to help surgeons better perform surgeries by decreasing their physical fluctuations and providing updated information during the operation.
- Monitoring patients, such as using wearable devices, sensors, or apps to track the patient’s vital signs, symptoms, or behaviors, and alert the healthcare providers or the patients themselves of any changes or anomalies.
- Supporting population health management, such as using AI to analyze large-scale data from various sources, such as EHRs, social media, or environmental factors, and identify patterns, trends, or risks that affect the health outcomes of a community.
Administrative AI Tools
Administrative AI tools are those that indirectly assist with patient care, such as:
- Recording digital notes, such as using speech recognition or NLP to transcribe the verbal interactions between the healthcare providers and the patients, and automatically document them in the EHRs.
