Here’s a step-by-step procedure of how to build a generative AI solution for the healthcare industry.
Step 1: Define Generative AI Goals for your Healthcare System
To effectively implement a Generative AI solution in healthcare, it is crucial to first identify the specific tasks it will undertake.
Prioritize functions that are either highly challenging or require significant human resources.
For each selected task, the AI must be trained on historical data to ensure accuracy and relevance. These are a few possible applications with the current state of Gen AI:
- Generative AI can meticulously analyze extensive medical data, and help in precise diagnosis of diseases. This capability is particularly valuable in identifying subtle or complex conditions.
- Utilizing AI technology, healthcare providers can develop personalized treatment plans. These plans are based on the unique medical history of each patient.
- By integrating AI into hospital operations, there is a significant opportunity to streamline administrative processes.
- In the realm of drug discovery and medical research, AI has the potential to significantly expedite the development process.
Selecting the right tasks for your Generative AI solution involves focusing on areas that present the greatest challenges.
Step 2: Understand your Healthcare Data Collection and Data Infrastructure
Begin the process of building a generative AI solution by gathering relevant data that will fuel the algorithm. The efficacy of these AI models hinges on the quality of the data they are trained on.
High-quality data, free from errors and inconsistencies, is essential for the accuracy and reliability of AI-driven decisions. Should the data contain inaccuracies or biases, the resulting outputs could be unreliable, potentially leading to erroneous treatments.
This is especially vital for the healthcare industry where any discrepancies in data can lead to negative outcomes for patients.
Strict Data privacy laws have also led to most healthcare institutions using synthetic data for electronic health records. This ensures that replicas of electronic health records (EHRs) of patient data are used to ensure patient confidentiality. Proper data storage is equally important to prevent any leaks from the healthcare systems.
Moreover, strict adherence to regulatory standards, such as HIPAA and GDPR, is crucial in safeguarding sensitive health information. These regulations ensure that patient data is handled with the utmost confidentiality and security, maintaining trust and integrity in healthcare AI applications.
Step 3: Choose the Right AI Platforms and Tools
Not all Gen AI platforms are created equal. For example, some platforms excel at natural language processing, making them ideal for chatbots and virtual assistants. Others shine in data analysis, aiding in clinical decision-making and risk prediction.
For healthcare applications, you may want to consider the following generative AI solution providers:
IBM Watson Health (Formerly Merative L.P.)

Before you build a generative AI solution and train it, you need a prototype. Here is how to build a generative AI application PoC.
- Choose a specific, manageable use case for the PoC. This should be a representative scenario where the AI solution can have a significant impact. For example, a PoC might focus on using generative AI applications to analyze radiology images to detect bone fractures.
- Collect and prepare the data required for the PoC. This could involve anonymized imaging data. Ensure the data is of high quality and representative of the real-world conditions the AI will encounter.
- Configure the AI model to address the chosen use case. This involves training a machine learning model on the collected data. An expert would have to guide it through the first several thousand images.
- Run the PoC in a controlled environment to evaluate its performance. Monitor how well the AI solution works in terms of accuracy.
It is time-consuming and can take many months but thereafter the system keeps fine-tuning itself. Think of the system as an infant that learns about the alphabet, reads a few books, and then starts writing.
Step 6: Evaluate and Check for Biases Within Your Healthcare AI Model
AI model bias is a significant challenge that can lead to inexact outcomes.
For example, if an AI system used in a hospital is trained mostly with medical data from male patients, it might not be as good at diagnosing diseases in female patients. It is not that men and women have entirely different physiology but older women have significantly more fractures than men due to osteoporosis.
To correct AI model bias take these steps:
- Ensure the training data is diverse and representative of the population the model will serve.
- Embed ethical considerations and fairness criteria into the AI development process.
- Regularly test the AI models for bias by checking the model’s outputs against various demographic groups
Building an AI algorithm must happen with transparency and explainability in mind. Understanding how and why a model makes certain decisions is crucial for identifying and correcting biases.
Bias correction is not a one-time task. Continuous monitoring and updating of the AI models are necessary.
Step 7: Maintain Your Generative AI Solution and Check for Improvements
