Strategic Recommendations for 2025 and Beyond

As the demand for AI-powered healthcare solutions increases, companies planning to develop AI agents must approach the project with a clear strategy. Here are five strategic recommendations to guide the development of AI agents in healthcare for 2025 and beyond:

1. Start Narrow. Expand Later.

One of the biggest mistakes made by healthcare AI developers is trying to solve too many problems at once. In the early stages, it’s crucial to focus on a single, narrow use case and optimize that before expanding to other areas. For example, building an AI-powered medication reminder system or a symptom checker can provide immediate value with relatively lower risk. This allows the development team to gain critical insights, refine their technology, and establish a user base. Once the solution is stable and well-received, it’s easier and less expensive to expand into more complex areas like predictive analytics for chronic disease management or clinical decision support tools.

Starting with a narrow focus reduces the financial burden, simplifies regulatory approval processes, and helps in establishing a product-market fit. Healthcare is complex and developing AI agents that solve multiple problems at once can overwhelm the team, increase costs, and potentially create regulatory and safety challenges. Therefore, prioritizing a single, clear use case will enable teams to iterate faster, attract early adopters, and gain valuable feedback.

2. Prioritize Exploitability from Day One.

In the healthcare sector, the “black-box” nature of many AI models is a significant obstacle. Regulatory bodies like the FDA and EMA, as well as healthcare providers, often require AI models to be interpretable to ensure accountability and transparency in clinical decision-making. In 2025, regulatory frameworks will likely continue to demand greater exploitability and justification for AI-based decisions.

Designing explainable AI systems from the beginning will help mitigate regulatory hurdles and build trust with healthcare professionals and patients. It’s crucial to create AI models that can provide clear, understandable explanations for how they arrived at a certain conclusion. Whether it’s a recommendation for medication, a diagnostic output, or a triage suggestion, an AI agent must be able to explain its reasoning in a way that clinicians can understand and act upon confidently.

This will not only ensure compliance with regulations but also enhance the adoption of AI tools by clinicians who need to trust the recommendations made by the system. Creating transparent models early on will be a critical factor in long-term success.

3. Bake Compliance into Initial Design.

HIPAA, GDPR, and other regulatory frameworks have strict requirements for data security, privacy, and patient confidentiality. Compliance is a non-negotiable aspect of any healthcare-related AI project, but it can be costly if not addressed early on. Retroactively fitting an AI system into these regulations can often triple development costs, due to the need for rework, additional testing, and documentation.

To avoid such costs, it’s essential to integrate compliance considerations into the design and development process from the outset. This includes adopting secure coding practices, ensuring proper data encryption, and creating user authentication mechanisms. The earlier compliance is baked into the project, the smoother the approval process will be and the lower the chances of costly rework. Additionally, early attention to compliance ensures that the product meets both legal requirements and the ethical standards expected in healthcare, such as patient data privacy.

4. Use Fine-Tuning and Transfer Learning.

AI development is inherently resource-intensive, especially when training models from scratch. In healthcare, however, there are many pre-trained models and datasets available that can be leveraged to save significant time and money. Fine-tuning and transfer learning allow developers to start with a pre-existing model that has already been trained on a similar task and adjust it to suit the specific needs of healthcare.

By utilizing fine-tuning, healthcare AI developers can avoid the expense of training models from scratch while still obtaining accurate, tailored outputs. Pre-trained models such as those developed for image recognition or natural language processing can be adapted for specific healthcare applications like diagnostic imaging or clinical notes processing. This strategy can dramatically reduce the costs associated with acquiring large datasets and training models from scratch, while still achieving the desired performance.

5. Invest in Data Infrastructure Early.

Data is the foundation of any AI system, and in healthcare, the quality of data is paramount. However, building good datasets takes time, effort, and resources. Investing in data infrastructure early in the project lifecycle allows for the systematic collection, cleaning, and organization of healthcare data. High-quality, well-labeled datasets form the basis for building accurate and robust AI models.

A well-designed data infrastructure can be reused across multiple products, enabling AI teams to scale more efficiently and amortize the initial investment over time. Instead of starting fresh with every new product, teams can reuse and refine datasets for new use cases, which makes future product development faster, cheaper, and more reliable. Additionally, leveraging data governance tools to ensure data integrity, privacy, and security will help streamline compliance efforts and prevent costly issues down the line.
