Back to Basics: Predictive and Generative AI in Healthcare

AI Basics

Artificial Intelligence (AI) is revolutionizing many industries, and healthcare is no exception. As this technology rapidly permeates the medical and digital sectors, this article aims to provide a comprehensive explanation of AI as it relates to medical practice.

Understanding AI

AI is evolving rapidly, with new articles and tools constantly emerging, so it can feel like you're always out of date. As a healthcare marketing agency, it's our job to help healthcare leaders succeed in this competitive digital environment. In this article, we'll demystify some of the AI ​​terminology you may encounter.

What is AI?

AI (Artificial Intelligence) is a field of computer science that focuses on creating machines and software that can perform tasks that typically require human intelligence. These tasks include answering questions accurately, solving math problems, writing code, etc. Simply put, AI allows computers to perform tasks by mimicking human thoughts and behaviors.

The history of AI in healthcare spans decades. In the 1970s, early AI systems such as MYCIN and INTERNIST-1 were developed to assist with medical diagnosis, showcasing the potential of AI in healthcare. Breakthroughs came with the introduction of natural language processing in the 2010s, improving communication between AI systems and humans. A notable example is Pharmabot, a chatbot developed in 2015 to assist with medication education for pediatric patients and their parents. Today, AI is poised to revolutionize healthcare by improving diagnostic accuracy, personalized medicine, and operational efficiencies.

Without getting too deep into the computer science aspects, creating artificial intelligence involves developing an algorithm (a set of instructions), coding these instructions into software, and training the model to perform specific tasks.

Core Components of AI

AI typically encompasses a wide range of algorithms and techniques, including:

Machine Learning (ML): This is a subset of AI that allows a system to learn and improve from experience without being explicitly programmed. For example, if a machine learning model is designed to recognize images of cats, it will look at thousands of images of cats and non-cats. Over time, it will be able to identify the features that distinguish cats from other objects.

Deep Learning: This is a more advanced type of machine learning. It uses neural networks, computer systems inspired by the human brain. These networks can learn from large amounts of data to recognise patterns and make decisions, making this method particularly well suited to tasks like facial recognition and speech understanding.

Natural Language Processing (NLP) is a branch of machine learning that teaches computers to understand and use human language – for example, it enables your mobile phone to understand voice commands and chatbots to understand questions and respond with human-like dialogue.

Robotics: This branch of AI involves designing and building robots. Robots are physical machines that can perform tasks independently or semi-independently. Robotics integrates AI to enable these machines to perceive their environment, make decisions, and take actions. An example would be a self-driving car.

Types of AI

AI comes in many forms, but the two main ones are generative and predictive.

Generative AI in Healthcare

Generative AI refers to systems that can create new content, such as text, images, or audio. These systems use advanced models to generate outputs that are similar to, but not directly copied from, the training data. One notable example is ChatGPT. GPT stands for “Generative Pre-trained Transformer” and is a type of deep learning model developed by OpenAI.

  • Driving force: It can create new content based on the input it receives.
  • Pre-trained: It is initially trained on a large dataset to learn how human language works.
  • Transformer: It is designed to effectively understand and process sequences of text such as sentences and paragraphs.

Potential/Applications of Generative AI in Healthcare:

Chatbots for websites: ChatGPT's xx allows virtual assistants, like the one on your website, to be able to converse with patients more effectively and provide them with the guidance they need.

Medical Imaging: Generative AI can inspire medical scenarios – creating images from scans that show disease progression, helping doctors visualize how a condition progresses.

Medical Documentation and Management Services: Generative AI automates routine tasks such as writing medical reports, summarizing patient histories, and streamlining updates to electronic health records.

Predictive AI in Healthcare

Predictive AI uses historical data and machine learning techniques to identify likely future outcomes. It is designed to forecast future events, trends, and behaviors. These systems use machine learning and statistical modeling techniques to analyze large data sets and identify patterns that help with predictions.

Predictive AI is being applied across a variety of industries to help organizations make more informed decisions, anticipate future needs, and improve efficiency.

Potential/Applications of Predictive AI in Healthcare:

Audience Targeting: Predictive analytics in marketing, such as Google Analytics, can help you target potential patients by analyzing historical data to predict who is most likely to convert.

Patient Risk Assessment: AI can look at patient data and predict which patients are at higher risk for certain diseases, such as heart disease or diabetes.

Hospital Resource Management: AI can predict patient admissions and optimize resource allocation, staffing, and bed management to improve hospital efficiency.

The Future is Now: Predictive and Generative AI in Healthcare

Overall, AI has great potential to transform nearly every aspect of healthcare over the next few years, and it's important to have a marketing team that stays up to date on the latest advancements in predictive and generative AI in healthcare. Understanding AI, including its core components and types, is crucial for healthcare leaders who want to effectively leverage the benefits of AI in this rapidly changing environment.
