Here at NiaHealth, we believe AI is essential to providing the customer experience that we envision. Our company's approach to integrating AI is guided by the insightful perspective of our head of engineering, Saif Mahmud. Saif claims that our company's goal is relatively simple: “We want to analyze all aspects of our patients’ health to provide them with a personalized easy-to-follow action plan that will help them mitigate their biggest risks and achieve their healthspan goals”. 20 years ago this goal would have been impossible but with the promise of today's technology, Saif and NiaHealth’s goal is becoming more and more attainable.

A Synergy Between AI and Healthcare Workers

To fully harness the power of AI in healthcare, we must drive innovation with careful consideration and awareness. First and foremost, it is crucial that healthcare professionals understand how AI technologies function in order to leverage them effectively. AI systems only provide value when they are used with purpose and diligence by those employing them. Saif emphasizes that the successful integration of AI in healthcare extends beyond just developing advanced systems. HHe believes the success of AI’s integration into medicine will largely depend on our ability to leverage and engage with these technologies effectively. 

Saif's philosophy is encapsulated in a compelling analogy: 

"Just as an X-ray is a tool for screening that requires a skilled professional to interpret and use effectively, AI is a tool that provides value when it is properly and responsibly used by capable workers."  - Saif Mahmud

Dr. David Lendrum and his AI Note-Taker

A textbook example of how we envision the synergy between healthcare workers and AI is playing out is from one of our clinical advisors, Dr. David Lendrum. David is a practicing medical professional in Calgary who works in a stressful emergency department. He explains that with his team, LLM tools are being trialled for note-taking and generating clinical documentation. David emphasized that automating these tasks can allow him and his team to refocus on their primary role: engaging with patients and making decisions that require human sensibility.

As this experiment is still being trialled, David has many considerations that he keeps in mind while using the model. First off, before he starts recording, he always ensures that his patients consent to the use of his AI model. With the AI ready to record the conversation, David can focus his efforts on accurately probing the patient in a fluid and direct manner. This not only saves David valuable time but enables a more engaging and personal experience for the patient. The resultant note-taking process is more accurate, comprehensive, and timely, all while maintaining the human connection between David and his patient.

Although all the physical documentation is created by the AI, the content of the notes is still determined by David. If David didn’t have the qualified expertise to direct the conversation and ask relevant questions, then the AI note-taker would have little value. David also explains that he is constantly revising his script to transcribe the notes in the most concise and easily digestible way possible. 

Now David is no AI guru, but he demonstrates that he knows how to leverage these technologies in a responsible and effective manner to generate his desired results. The value of these technologies is compounded by both David’s medical knowledge and his understanding of these AI systems. This is why it’s so crucial that healthcare workers remain educated and involved with these AI processes to properly implement the technology.

Leveraging Patient Data Responsibly

The second key consideration is that we remain responsible when it comes to using patient data. Since AI systems work by accessing massive amounts of patient data, the conservation of privacy and mitigation of bias must remain key priorities.

‍

Patient Data Privacy

Healthcare information is among the most sensitive personal data, encompassing not just identifying details but comprehensive medical histories and intimate health information. When this data is fed into AI systems, it becomes both more valuable and more vulnerable. Inadequate security measures can lead to severe consequences, including privacy breaches, identity theft, and erosion of patient trust in healthcare institutions and AI technologies.

Essential security measures must be put in place to mitigate these risks. These include but are not limited to:

• Encrypt data both in transit and at rest: Protect data during transmission and storage using encryption techniques to prevent unauthorized access.
• Implement strict access controls: Restrict data access to authorized personnel only, using strong authentication and authorization measures.
• Anonymize or pseudonymize data: Remove or obscure personal identifiers to protect patient identities.
• Secure the infrastructure: Protect systems and networks against breaches and unauthorized access with robust security protocols.
• Conduct regular security audits: Frequently assess and address potential vulnerabilities.
• Provide robust employee training: Educate staff on data protection protocols and best practices to ensure secure handling of patient information.
• Obtain informed patient consent: Secure explicit permission from patients before using their data for purposes beyond immediate medical care.

By prioritizing data security in AI-driven healthcare, we can leverage the full potential of these technologies while maintaining patient privacy and trust, balancing advancements in medical care with the protection of individual rights.

‍

Algorithmic Bias

A less obvious concern is that AI models fall under the serious risk of contributing to algorithmic bias. AI systems can inadvertently perpetuate or even exacerbate existing health disparities if they're trained on biased data or if their algorithms aren't carefully designed to account for diversity.

AI algorithms largely rely on unmoderated data to discover trends. One of the downsides to this approach is that the data does not always reflect an accurate representation of the population. A 2019 study published in the journal Science found that an algorithm designed for predicting healthcare needs underestimated the needs of black patients compared to white patients. The algorithm assessed need based on healthcare expenditure, but it underestimated the health needs of black patients. Historically, black patients have spent less on healthcare compared to white patients, leading to this miscalculation. When further analyzed the researchers concluded that this algorithmic conclusion was biased by systematic wealth inequalities rather than actual healthcare needs.

Saif stresses the importance of diverse datasets and rigorous testing to mitigate bias:

"We need to ensure our AI systems are trained on data that represents the full spectrum of the population they'll serve," he explains. "And we need to continuously monitor and adjust these systems to identify and correct any biases that emerge." - Saif Mahmud

This is an ongoing challenge that requires vigilance and a commitment to equity in healthcare. It's not enough to simply develop powerful AI tools; we must ensure these tools work fairly and effectively for all patients, regardless of their background. This will enable healthcare to be more personalized, not just for the majority but for all demographics.

The Role of Innovative Firms

It's important to recognize that established healthcare systems and large hospitals often face challenges in adopting new approaches. These institutions, responsible for the care of millions, must prioritize patient safety and regulatory compliance, which can naturally lead to a more conservative approach to innovation.

This risk-averse stance, while understandable, can slow the pace of development. That's where smaller, more agile healthcare companies come into play. Companies like Nia Health have the flexibility and innovative spirit to drive forward new ideas and technologies, acting as pioneers in the field.

As an upcoming organization, we can move quickly, test new concepts, and iterate based on real-world feedback. This agility allows us to push the boundaries of what's possible in AI-driven healthcare while still maintaining a strong focus on patient outcomes and data security.

We must keep in mind that we are not just innovating for the sake of it. We understand the valid concerns that larger healthcare institutions have regarding new technologies, particularly when it comes to patient privacy, data security, and the reliability of AI-driven insights. As we develop new solutions, we keep these concerns at the forefront of our minds, ensuring that our innovations not only push the envelope but also meet the rigorous standards expected in healthcare.

Embracing AI for a Brighter Healthcare Future

As we stand on the brink of this AI-driven transformation in healthcare, it's crucial to approach it with both optimism and careful consideration. By embracing AI's potential while addressing its challenges head-on, we can work towards a future where artificial intelligence and human expertise can responsibly build off one another.

Ultimately, the promise of AI in personalized healthcare is not just about better treatment of diseases, but about a fundamental shift towards optimizing health and wellness for each individual. It's about moving from a system that treats you based on how you're similar to others, to one that treats you based on what makes you unique. This is the true revolution of AI in healthcare – a future where each person's journey to health is as individual as they are.
