Generative AI in Healthcare: Developing Customized Solutions with Neural Networks

A subset of artificial intelligence, generative AI  is poised to redefine how healthcare is delivered. 

By creating new data instances that mimic real-world patterns, generative AI in healthcare can transform drug discovery, medical imaging, personalized medicine, clinical documentation, and more.

A recent research effort by McKinsey & Company surveyed 150 healthcare stakeholders and found integrators very interested in generative AI solutions (in payer organizations, health systems, and healthcare tech), illustrating that the application of generative AI in healthcare is moving from concept to action.

What this really means is that healthcare organizations are starting to place meaningful bets on generative AI, not just in pilots, but in strategic adoption.

Yet, healthcare is complex, regulated, and varied. A “one-size-fits‐all” generative AI in healthcare solution won’t deliver maximum benefit. Tailoring AI models to specific clinical, operational, and regulatory settings is critical.

In this blog, we explore:

• What generative AI models are (and why they matter in healthcare)
• Current & emerging applications of generative AI in healthcare
• Fresh research findings and what they tell us about where we’re headed
• Challenges specific to healthcare adoption
• How to approach customized generative AI in healthcare solutions.

Understanding Generative AI Models

“Generative AI in healthcare” refers to the use of AI models to generate new data or insights (such as synthetic images, text, signals, or tabular data) that mirror or augment real, clinically relevant data.

Key architectures include:

• Generative Adversarial Networks (GANs) – Two networks (generator + discriminator) compete so that the generator produces ever more realistic “fake” data and the discriminator learns to distinguish fake from real.
• Variational Autoencoders (VAEs) – Encode data into a latent (compressed) space, then decode it back. By sampling in the latent space, you can generate new data instances.
• Diffusion Models / Denoising Models – a more recent class of generative models that gradually modify noise to recover new samples; increasingly used for images and signals.
• Large Language Models (LLMs) and multimodal generative models – For text, combinations of text+image, or other modalities (e.g., EHR text, clinical notes).

Here’s what recent research shows:

• A 2024 systematic review covering generative models (GANs, VAEs, diffusion, LLMs) across multiple medical modalities (imaging, ultrasound, CT/MRI, text, time-series, tabular) found that while synthetic data production is growing fast, the use of that synthetic data beyond augmentation (e.g., for validation or downstream evaluation) remains limited.
• Another paper (2025) emphasizes that generative AI has rapidly evolved since 2022 and is now being deployed in clinical practice and research for medical documentation, diagnostics, patient communication, drug discovery, and more.

What this really means is: we’ve moved from “look how cool GANs are” to “here is how generative AI in healthcare actually works in real-world settings, and what we still need to tackle”.

Core Applications of Generative AI in Healthcare

Here are several domains where generative AI is delivering (and evolving) value.

1. Medical Image Generation and Enhancement

• Synthetic data to mitigate scarcity & privacy: Generative AI models generate synthetic medical images (e.g., X-rays, MRIs, CTs) that help train downstream AI without exposing real patient data. Research in synthetic EHR and imaging confirms this trend.
• Image quality improvement: Low-quality scans (noise, motion artifacts) can be enhanced using generative models, thereby improving diagnostic accuracy.
• Rare condition simulation: Synthetic images allow augmentation of under-represented disease classes, helping models learn rare patterns.

Example: A study on cardiovascular disease (CVD) mortality prediction used GAN‐generated synthetic data and demonstrated promising applicability.

2. Synthetic Data for Tabular and EHR Data

• Generative models are used to create realistic synthetic electronic health record (EHR) data that maintain statistical and structural properties of real data, enabling data sharing & research without exposing sensitive information.
• A new framework (‘Bt-GAN’) specifically tackles fairness in synthetic health-data generation to reduce bias in downstream predictions.

3. Drug Discovery & Molecule Generation

• Generative AI in healthcare is increasingly used to design novel molecules, predict bioactivity, and optimize candidate properties (safety, efficacy).
• A recent article in Cell refers to generative AI as a “transformative tool” for accelerating biomedical research (including drug discovery) thanks to large datasets and specialized compute.

4. Personalized Medicine & Treatment Planning

• Generative approaches simulate different patient trajectories (disease progression, treatment response) based on individual data.
• This supports personalized plans, risk stratification, and scenario modeling.
• Moreover, a 2024/25 review highlights that generative AI touches areas such as customized treatment plans, risk prediction, surgical outcome support, nursing workflow, and population health.

5. Clinical Documentation, Workflow Automation & NLP

• Beyond imaging or molecules, generative AI is making inroads into administrative and documentation workflows: auto-drafting clinical notes, transcription, summarizing patient-clinician interactions, etc. A study on clinical note generation shows the promise and risks of LLMs in this domain.
• Reducing clinical admin burden is a major operational win for healthcare systems.

6. Operational and Non-Clinical Use Cases

• Generative AI in healthcare also extends to revenue cycle management, marketing, supply chain optimization, workforce planning, and more.
• For India: A report on GenAI in Indian healthcare forecasts productivity gains of ~30-32% by 2030, driven by both clinical and non-clinical uses.

New Research Highlights & Future Trends

Let’s break down some of the most recent and forward-looking findings in generative AI in healthcare:

• The “generative era” of medical AI: A Cell commentary emphasizes that we’ve reached a phase where generative AI isn’t just experimental—it’s integrated into large-scale biomedical research, enabled by petabyte datasets and advanced hardware.
• Synthetic data evaluation gap: A systematic review across medical modalities (imaging, time-series, text) highlighted a major gap: there are no standardized evaluation methodologies tailored to medical synthetic data. Without that, clinical adoption is hampered.
• Fairness in synthetic health data: The Bt-GAN framework specifically addresses bias among synthetic EHR data generation, going beyond “just generate more data” to “generate fairer, unbiased data.”
• Generative AI in clinical research regulation: Agencies such as the U.S. Food & Drug Administration (FDA) and the National Institutes of Health (NIH) are issuing guidance on the use of generative AI in research settings, hinting at the field’s growing maturity.
• Broad trend capture: Consultancies identify that generative AI is shifting healthcare from “reactive” to “predictive/proactive” care models. For example, workflow automation, chronic-disease management & personalized treatment are getting a boost.

What this really means: If you’re thinking of applying generative AI in healthcare (for example, via your organization), you should no longer treat it as “emerging tech we’ll pilot sometime.” Instead, it’s about choosing where to apply it (use-case focus), how to evaluate it (metrics + clinical validation), and how to scale it (governance & clinical translation).

Challenges and Considerations

Data Privacy & Security

• Healthcare data remains highly regulated (HIPAA, GDPR, local laws), and generative AI that handles patient data (or generates synthetic data) must adhere to these rules.
• Synthetic data helps, but recent research emphasizes the quality & utility of synthetic data (not just “fake data”) as critical. E.g., synthetic EHR datasets used for cardiovascular mortality prediction.
• Evaluation standards for synthetic health data remain immature — impacting trust and regulatory acceptance.

Ethical Implications

• Bias & fairness: Synthetic data can amplify biases if the underlying data is skewed or if the generation doesn’t account for subgroup representation. Example: Bt-GAN work addresses this explicitly.
• Explainability / Interpretability: Generative models often operate as “black boxes”. In clinical settings, this is a barrier to adoption — clinicians need to trust the AI-generated output.
• Responsible use & oversight: Since generative AI can generate data or produce predictions, human-in-the-loop governance is essential to ensure safety and proper use.

Clinical Translation & Validation

• Generating synthetic data or predictions is one thing; validating them in clinical workflows is another. The lack of a standard benchmark for synthetic data is a barrier.
• Integration with existing systems (EHRs, imaging workflows, clinician dashboards) remains non-trivial.
• Regulatory frameworks are still catching up. Although agencies are issuing guidance, deployment needs compliance.

Operational / Organizational

• Skills gap: Healthcare organizations need collaboration between clinicians, data scientists, and AI engineers.
• ROI and use-case selection: Not all generative AI use cases generate high value; prioritization matters.
• Trust & adoption: Clinicians must be comfortable with the output, and workflows need to adapt.

Developing Customized Generative AI in Healthcare Solutions

Importance of Domain Expertise & Collaboration

The intersection of clinical domain knowledge + AI expertise is even more critical now.

• Recent studies show that many healthcare AI projects still fail due to a lack of domain expert integration.
• Use-case selection: A deep understanding of the healthcare context, patient journey, disease pathways, and clinical workflows is essential.
• Collaboration among stakeholders (clinicians, hospital IT, data scientists, regulatory/legal) ensures solutions map to real needs rather than just “cool tech.”

Data Preparation, Curation & Synthetic Data Strategy

• Data quality, diversity, and annotation remain foundational. But beyond that, a synthetic data strategy is now key. Organizations must decide when to use synthetic vs. real data, how to evaluate synthetic data, and how to integrate it for training/validation.
• Because evaluation standards are still emerging, establishing internal benchmarking and quality metrics for synthetic datasets is recommended.
• Consider privacy-preserving techniques such as federated learning and differential privacy combined with generative AI.
• In geographies like India, adoption of generative AI is accelerating, but legacy systems and uneven data availability remain constraints.

Model Training, Fine-Tuning, and Deployment

• Select the exemplary architecture: GAN, VAE, LLM, diffusion model based on the use case (imaging, text, EHR) and target modality.
• Transfer learning and fine-tuning on domain-specific health care data can speed up development.
• Continuous learning: As healthcare data evolves and workflows change, models must be retrained/refined.
• Monitoring & governance: Especially in healthcare, real-world monitoring of model performance, bias drift, and adverse outcomes is critical.
• Explainability: Choose architectures and interfaces that allow clinicians to interrogate outputs and understand logic where possible.

Customisation & Use-case Prioritisation

• Prioritize based on impact: e.g., care for high-volume conditions, workflow bottlenecks, and rare disease diagnosis where synthetic data helps the most.
• Customize for patient population: region, demographics, disease prevalence, data availability.
• Operational readiness: Ensure integration into clinical systems, regulatory compliance, and clinician workflows.
