The Impact Of Explainability In Healthcare Ai Powered By Anns – As AI-powered healthcare, research and development, therapies, clinical trials, care planning, and day-to-day tasks become increasingly the norm in the industry, the issue of trust in opaque models and unfounded insights is preventing stakeholders from fully embracing data-driven care and optimized patient outcomes accept. Rushabh Padalia, Partner at , explores how explainable AI, with its ability to provide transparency and trust in everyday decisions, is the natural answer to this trust problem.

Q: From predictive analytics and context-aware applications to automation and computer vision, we have already seen widespread adoption of AI in healthcare. Why is explainable AI the need of the hour for healthcare organizations?

Rushabh: While AI spending grew exponentially across industries in 2020, it was naturally expected that healthcare would be at the forefront of this boom. However, the numbers tell a whole new story: AI in the healthcare market alone is expected to grow at an annual rate of 46.2%, as opposed to just 20.1% for all other industries combined.[1]

The Power Of Explainable Ai: Bringing Transparency And Trust To Artificial Intelligence

With AI now playing an important role in drug development, precision medicine, disease prediction and many dimensions of healthcare, its importance in the global context will only increase. However, this expansive growth has also brought the idea of openness and trust in closed AI models into the spotlight. Because healthcare decision-making often has a direct and critical impact on patient health outcomes, many stakeholders are understandably reluctant to rely on mathematical models in decision-making.

It’s gaps like these – between numbers and patient outcomes – that Explainable AI can effectively close and push new frontiers in healthcare automation. For example, when AI is used to identify high-risk patients for certain diseases, it is important to understand the factors that cause certain individuals to be highlighted as high-risk patients over low-risk patients in order to design timely interventions. In such scenarios, XAI typically helps healthcare professionals determine the number of visits a patient has had in the past 6 to 12 months, the combination of one or more acute and/or chronic conditions that may have been diagnosed, and the impact of certain conditions Understand treatments on similar risk populations based on previous data, etc. to provide comprehensive patient overviews.

The use cases for XAI in this space are truly diverse: whether it is for an insurance company to assess a potentially fraudulent claim to reduce operational costs; a drugmaker to accelerate the end-to-end phases of drug development to contain a pandemic; or in care management to identify the right patient populations for timely intervention, the Explain component of AI will give stakeholders the confidence needed to leverage AI across a range of healthcare applications and sub-segments.

Artificial Intelligence In Health Care

Q: Since XAI is achieved precisely by building “explainability” into algorithms and ensuring high-quality data, you can address how teams developing such models in the healthcare context can decide what kind of data to collect, capture and should be used?

Rushabh: With 1. the Centers for Medicare and Medicaid Services (CMS) interoperability mandate to always put the patient first when accessing data within and across entities (e.g., payers, providers, and pharmacies), and 2 .Rapid Interoperability for Healthcare Resources (FHIR). ), which define data exchange protocols and content models, data availability has continually and exponentially improved across the healthcare sector.

While no additional data collection or ingestion is required specifically for Explainable AI (XAI) – as it is always better for any type of AI model to capture different dimensions of data – the importance of data/feature engineering decreases in the context of XAI to . XAI requires the ability to slice the data so that the model output can be represented in different ways. Business-focused design thinking, the ability to trace data to data patterns, and even integrating explainable AI into blueprints, as in the case of Co.dx, our proprietary AI-powered platform, have proven useful in helping stakeholders have confidence in models and their results, enabling faster and more efficient decision-making.

Explainability In Machine Learning

Likewise, in the context of healthcare, the goal of developing an AI application should always be to reduce the cost of care, improve the quality of that care, improve patient health outcomes, and ensure that the models are accepted by the stakeholders who use them. are trustworthy. The following two use cases illustrate situations where XAI is critical to enabling the successful use of an AI model:

1. Automating prior authorization – where an AI model uses historical data to recommend to healthcare professionals such as nurses and medical directors to approve or deny a patient’s treatment and coverage – requires decision support from XAI components. really reliable. Such advanced features can create a comparison of historical patient requests with similar dimensions; view actual approved and rejected terms; and visually represent stakeholders’ predicted decisions – allowing each consumer of the model to more easily accept the predicted decision, accelerate decision making with clear insights, or even refute the predicted decision using computational reasoning.

2. As the emerging field of precision medicine brings together the complex and fascinating dimensions of patient demographics, clinical medicine and genomics, healthcare professionals need a holistic view of all three dimensions to deliver effective care. By understanding the impact of each of these three dimensions of precision medicine, for example by gaining insights into the interactions of lifestyle changes with genetic expression, XAI can effectively support healthcare professionals.

The Importance Of Explainability In Ai Decision Making

Q: Since healthcare is a highly individualized sector, how do you think organizations can develop and leverage AI systems that provide tailored explanations to meet individual patient needs at scale?

Rushabh: A significant problem that most healthcare professionals face today is that, although no two patients may be identical, from a clinical perspective they are often treated with the same diagnosis for the same disease. And this is exactly the kind of problem AI can solve with its ability to contextualize decisions quickly and at scale.

By analyzing large amounts of patient data, including demographic information, genomic profiles, environmental factors, prescription medications, laboratory tests, and hospitalizations, AI models can prescribe tailored medications and design-driven therapies that are unique to each patient’s needs.

However, to achieve this level of personalization, an AI system must be able to explain why it prescribed a particular medication or what factors played a role in recommending, for example, minimally invasive surgery over medication. Because the effectiveness of drugs and treatments can vary depending on patients’ genetic makeup and biomarkers, explanation is critical to limiting risk to patients and translating complex ML insights into successful health outcomes.

Clarity gives doctors more confidence in their decision-making process and can, for example, reduce the time spent analyzing scans. The right explainable system allows physicians to confidently assess recommendations based on a patient’s condition, detect anomalies, and make informed decisions in critical clinical situations.

Question: How does a more transparent and causal AI system support healthcare professionals at the operational level, from drug developers and medical representatives to healthcare professionals, insurers and drug distributors?

Rushabh: In addition to improving the patient experience and simplifying access to healthcare, AI will be crucial in improving the efficiency of healthcare professionals and the quality of care provided. At an operational level, explainability in AI systems can provide greater transparency across the healthcare value chain, as organizations, providers and systems benefit from universal access to patient data and greater transparency into a system’s decision-making reasons, resulting in improved workforce interoperability and diagnoses. Speed, accuracy and patient outcomes.

As EHRs enable life sciences organizations, healthcare companies and health insurers to better connect patient data, healthcare workers can now be better equipped to provide proactive care. For example, context-aware biomedical devices can retrieve contextual data from sensors and digital patient profiles to understand the context in which hospital staff perform their tasks. For example, for a nurse who has arrived for her shift and must care for a patient admitted in her absence, these contextual elements include her location, the time of service delivery, the dependency on other staff, and the location and condition of the ward . Here, a context-aware device integrated into hospital beds can ensure that the bed recognizes the patient, caregiver and diagnosis and displays relevant patient information, prescription history and next best care actions. This improved awareness reduces reliance on manual patient records and enables faster, more targeted care, with staff largely focused on patient-critical tasks.

Added to this is the improved “clarity of fundamentals” that comes from burnout.

To Win Trust, Business Leaders Must Take Control Of Ai

Q: The lack of trust in typically complex AI systems has only increased recently. Help us understand how XAI can help organizations restore and strengthen patient trust to deliver seamless care.

Rushabh: The key to scaling AI in healthcare is building patient trust in these systems. Since healthcare essentially involves a human component, the increasing reliance on digital systems often becomes a very basic but crucial sticking point for a patient’s trust in AI, coupled with varying digital skills, misunderstandings and much more.
