Join us as we navigate the intricate tapestry of personalized healthcare, where AI and ML take center stage in predicting treatment effectiveness and offering Case-based Reasoning for diagnoses. The recent maturation of AI, coupled with its newfound accessibility and affordability, opens doors for even small and mid-sized businesses to partake in the transformative journey of HealthTech. This blog will explore how these advancements contribute to a revolutionary shift, empowering practitioners and benefiting patients alike.

Current Landscape of Personalized Healthcare

Fueled by a range of groundbreaking genomic advancements, personalized medicine (PM) takes center stage in healthcare systems, particularly in the United Kingdom (UK), the United States (US), and the European Union (EU). Positioned as an emerging field, PM utilizes specific biological markers, often genetic, for more precise diagnosis and individualized disease management. 

The Human Genome Project, completed in 2003, marked a pivotal shift toward personalized medicine by enabling the identification of genetic variations associated with thousands of diseases. This breakthrough paved the way for genomics, facilitating fast, affordable, and accurate DNA and RNA sequencing. In the context of diseases like cancer, genomics plays a crucial role in tailoring treatments to individual patients based on their unique genetic information. By deciphering the complex interplay between genes and the environment, DNA sequencing identifies inherited genes that elevate susceptibility to specific cancers.

In recent times, a novel genomics strategy known as somatic mosaicism is pushing the boundaries of personalized medicine by customizing therapies to the unique cells of individual patients.

Challenges in Predicting Treatment Effectiveness

As the global adoption of Personalized Medicine (PM) technology, including in Southeast Asia (SEA), gains momentum, the implementation encounters a formidable challenge—high costs. Concurrently, the pursuit of Universal Health Coverage (UHC) by healthcare systems, aiming for accessible health services without imposing financial strain, faces a critical hurdle in overcoming financial constraints for PM.

Informed by the experiences of “early adopters,” a series of pressing issues surfaces: a dearth of evidence for clinical utility, inadequate awareness among providers, patients, and families, limited access to genetic testing, the absence of reimbursement structures for genetic testing, the essential need for real-time integration of test results with Electronic Health Records (EHR) and Clinical Decision Support (CDS) tools, and ethical, legal, and social concerns. Essentially, economic challenges and operational obstacles emerge as primary impediments to the progress and effective implementation of personalized medicine.

The Role of AI and ML, and CDSS in Healthcare

The healthcare landscape is witnessing a transformative wave driven by AI and ML particularly in the realm of Clinical Decision Support Systems (CDSS). As these technologies revolutionize medical practices, it becomes crucial to address key considerations for enterprises looking to harness their potential.

AI and ML in Healthcare: Navigating Data Challenges

The promise of AI and ML in healthcare is immense, with advancements in automated diagnostics, drug design, and treatment optimization. However, the efficacy of these technologies hinges on the quality of training data. Collating, cleansing, and annotating vast datasets are essential tasks, demanding a meticulous approach to ensure accuracy and relevance. Simultaneously, stringent measures to uphold patient privacy must be a top priority. Enterprises and HealthTech companies operating in this space need to navigate the delicate balance between data accessibility and safeguarding sensitive patient information.

The Collaborative Synergy: Healthcare and Data Specialists

Creating robust AI algorithms and establishing ML systems for continuous learning necessitate a collaborative effort between healthcare professionals and data specialists. The marriage of medical expertise with data science is essential to refine algorithms that not only diagnose accurately but also evolve with the dynamic nature of healthcare. Organizations must assemble interdisciplinary teams, fostering a synergy between healthcare practitioners who understand the nuances of patient care and data specialists equipped to harness the power of algorithms for improved outcomes.

Interoperability in CDSS: Crafting Secure Data Exchange

CDSS play a pivotal role in enhancing healthcare quality, safety, and efficiency. However, their effectiveness is contingent on seamless data interoperability. Enterprises venturing into this domain must grapple with the challenge of integrating CDSS with the myriad systems used in healthcare facilities. The expertise required extends beyond the development of CDSS itself, encompassing the setup of secure data exchange protocols within the facility and with external entities. Crafting a robust and secure infrastructure for data sharing is imperative to maximize the impact of CDSS on patient care.

CDSS Customization Based on Specialities

Operational in low-resource settings, CDSS proves advantageous where medical resources and qualified clinicians are limited. It is crafted to replicate the reasoning of medical professionals but in a faster, less error-prone, and cost-effective manner. It is categorized into knowledge-based and non-knowledge-based systems. Knowledge-based CDSS relies on medical guidelines, while non-knowledge-based systems use Machine Learning (ML), analyze historical clinical data and develop predictive models for clinical outcomes based on new inputs. ML-based CDSS holds significant promise in clinical practice by enhancing decision accuracy and minimizing medical errors through its objective, data-dependent decision-making logic. However, their effectiveness hinges on the quality and quantity of the data provided and is typically limited to one speciality. Multi speciality facilities may require multiple CDSS which introduces yet another layer of data integration

Another category within CDSS is the Case-Based Reasoning (CBR) system. The CBR model is an impactful paradigm that enables the application of knowledge derived from specific cases, previously encountered situations, or distinct patient scenarios to solve new cases. In radiotherapy for brain cancer patients, a CBR system can draw on past case data to help determine the optimal number of beams and ideal beam angles. Subsequently, medical physicists and oncologists would assess the suggested treatment plan for its practicality.
