How Generative AI Differs from Traditional AI in Healthcare

The term 'AI in healthcare' has been around for years, particularly with technologies like predictive analytics and Machine Learning, ML. So, what makes Generative AI so fundamentally different? The distinction lies in their core function; traditional AI classifies, predicts, or detects, while Generative AI ‘creates’. 

‍

Think of it this way, Traditional AI can tell you, with high accuracy, if a spot on an X ray is cancerous. It makes a judgment based on patterns it has learned. Generative AI can take a brief dictation from a doctor after a patient visit and automatically draft a complete, structured, and grammatically perfect Electronic Health Record (EHR) or note, or it can create a realistic, synthetic CT scan for training a diagnostic tool without compromising patient privacy.

This ability to produce entirely new, relevant content makes GenAI a game-changer for tasks that are currently time consuming and human intensive, like documentation, research, and personalised patient engagement. The power of NLP (natural language processing) and LLM (large language models) is a key component of this shift, enabling a new level of intelligent automation and personalisation.

With this difference in mind, the next step is to explore where GenAI is already creating real value in healthcare.

‍

Top Use Cases of Generative AI in Healthcare

Generative AI’s capability to create original content is solving some of the most critical and complex problems in modern medicine. This ability is driving real-world change in these key areas:

‍

Accelerated drug discovery and development

‍Drug development is notoriously slow and expensive, taking up to 10 years and costing billions of dollars. GenAI can analyse vast chemical and genomic databases to design entirely new drug molecules and proteins in a matter of days, something that used to take years. This significantly accelerates the research and development phase, offering a promising path to faster treatments.

‍

Automating clinical documentation

‍This is perhaps the most immediate relief for clinicians. GenAI acts as an AI scribe, listening securely to doctor-patient conversations and instantly drafting comprehensive, structured clinical notes and summaries. This frees up doctors and nurses from hours of tedious paperwork, letting them focus on actual patient care. 

‍

Generating synthetic patient data

‍Real patient data is essential, but it is also sensitive. GenAI solves this by creating large, realistic, but entirely artificial datasets that mimic real patient statistics. This allows researchers and developers to test new AI models and software without ever touching confidential protected health information.

‍

Enhancing medical imaging

‍GenAI improves the quality of diagnostics. It can take a low-resolution X-ray or MRI and enhance it into a sharp, clear image, helping radiologists spot subtle signs of disease earlier. It can also create draft reports from these scans, streamlining the diagnostic process.

‍

Improving patient personalisation and engagement

‍Using GenAI, healthcare providers can offer truly individualised care. It powers sophisticated virtual assistants that provide patients with personalised educational materials, answer questions about their care plan, and deliver custom reminders, leading to better patient adherence and outcomes. This is part of the broader push for highly personalised healthcare. 

‍

Modernizing IT systems‍

GenAI is even helping healthcare organisations in transforming application modernization by fixing their old, complex software. It can analyse legacy code and create modernised code snippets, accelerating the transition to robust, cloud-based systems. This process is vital for keeping up with the speed of digital transformation.

These use cases highlight how widely GenAI can be applied, so let us look at the benefits it brings across the entire healthcare ecosystem.

• Early and accurate diagnosis: The ability of GenAI to analyse medical images and lab results with incredible speed, identifying patterns a human might overlook, leads to earlier disease detection and improved patient outcomes. 
• Enhanced research and innovation- Researchers use GenAI to analyse trial data, generate patient cohorts, design molecules, and summarise findings. This accelerates the discovery pipeline for drugs, therapies, and clinical insights.

‍

Significant Reduction in Operational Costs

The financial strain on healthcare systems is immense. GenAI offers a path to considerable cost savings.

• Administrative cost savings: Automating documentation, billing, and scheduling tasks that can consume up to a quarter of hospital operating budgets- translates directly into millions of dollars in annual savings. 
• Reduced R&D costs: By simulating and synthesising potential drug candidates, GenAI drastically reduces the time and resources spent on dead-end research in the drug discovery pipeline. 

‍

Improved Patient and Clinician Experience

Perhaps the most humanised benefit is the improvement in daily life for both patients and providers.

• Focusing on Care: Automating tedious, repetitive tasks helps combat the rising tide of clinician burnout, allowing doctors and nurses to spend more time interacting with patients rather than with screens and paperwork. This is part of the larger conversation about how GenAI can help address healthcares greatest challenges, a topic we explore deeply in our podcast episode on Gen AI in healthcare.

GenAI can unify information from EHRs, IoMT devices, medical images, and claims data. Secure cloud computing in healthcare enables teams to access and use real-time health data in a compliant way.

However, even with substantial advantages, GenAI also comes with challenges that healthcare organisations must manage carefully.

‍

Challenges and Risks of Applying Generative AI in Healthcare

While GenAI is amazing, using it in a field as serious as healthcare comes with big challenges. That means organisations need to consider potential risks before scaling their solutions. Here are the most important challenges explained:

‍

1. Data security and patient privacy

• The Risk: GenAI models learn from huge amounts of information. If real patient data is misused, or if the model accidentally shares private health details, it's a major privacy disaster.
• The Solution: Everything must follow strict privacy laws like HIPAA. We need to use fake, "synthetic" data for training as much as possible to keep real patient records locked down.

‍

2. Accuracy, 'hallucinations,' and trust

• The Risk: AI is creative, and sometimes it just makes things up; we call these ‘hallucinations’. A hallucination in a clinical note or a treatment suggestion could put a patient's life at risk.
• The Solution: A human doctor or clinician must always review and approve any key suggestion or summary created by the AI. GenAI is a tool to help, not a boss to follow blindly.

‍

3. Algorithm bias and health fairness

• The Risk: If the data used to train the AI only comes from one group of people (e.g., a single race, age group, or region), the AI will likely perform poorly or incorrectly for everyone else. This exacerbates existing health inequities even further.
• The Solution: We must carefully check the training data to make sure it represents everyone, so the AI works equally well for all patients.

‍

4. Difficulty integrating with old systems (interoperability)

• The Risk: Most hospitals and clinics utilise outdated computer systems and software, including legacy Electronic Health Records (EHRs). These systems were not designed to interact seamlessly with advanced, modern GenAI tools. Trying to connect the old to the new often causes technical headaches and crashes.
• The Solution: Organisations need a smart strategy to connect these systems, often using special connectors, so the new AI tools can smoothly pull information from and push information back into the existing patient record systems.

‍

5. Clear accountability when things go wrong

• The Risk: If a GenAI tool makes an incorrect suggestion that leads to a mistake, who is responsible? Is it the doctor who followed the suggestion, the hospital that bought the software, or the company that built the AI? The legal and ethical lines are currently blurry.
• The Solution: Clear policies must be established immediately to determine who is accountable for any errors. This ensures there is oversight and that trust in the clinical process can be maintained.

‍

6. High Cost of Building and Running the Technology

• The Risk: Building a large, custom AI model for healthcare and training it on massive amounts of data is very expensive. Furthermore, running these powerful models day-to-day (the operational costs) can be incredibly high, making it difficult for smaller clinics or hospitals to afford.
• The Solution: Healthcare providers should partner with companies to find cost-effective ways to deploy, perhaps by using existing cloud-based solutions or sharing infrastructure, to make AI affordable for all.

‍

7. The 'Black Box' Problem (Lack of Transparency)

• The Risk: Many advanced AI models are like a black box. They can give you a correct answer, but the steps they took to get that answer are hidden and impossible for a human to follow. In medicine, where 'why' is critical for trust and safety, this lack of transparency is a major issue.
• The Solution: We must push for Explainable AI tools that can clearly show the evidence and the data points they used to reach a conclusion, making the process clear and trustworthy for clinicians.

‍

8. Need for New Skills and Training

• The Risk: GenAI changes how doctors and nurses work. They need new training on how to use these tools effectively, how to spot an AI 'hallucination,' and how to use the AI's suggestions as a starting point, not a final answer. If staff aren't trained properly, they might mistrust the technology or use it incorrectly.
• The Solution: Hospitals need to invest in extensive, ongoing training for all staff to make sure the human team and the AI team work together seamlessly and safely.

‍
