How Digital Twins May Unlock a More Human-Centered Healthcare System

Virtual modeling is revolutionizing healthcare through "digital twin" technology, enabling the creation of virtual replicas of organs, systems, and even entire patients to enhance treatment personalization and operational efficiency. These digital models facilitate a range of applications, from testing surgical techniques to forecasting how medical systems might react during crises, such as pandemics.

The surge in digital twin adoption is largely driven by advancements in artificial intelligence and cloud computing, which make these complex models accessible and cost-effective. By 2025, it is projected that a quarter of healthcare delivery organizations will implement digital twins in their operations. This technology allows healthcare professionals to run "what-if" scenarios, helping them assess risks and optimize decisions, thereby minimizing potential errors.

In British Columbia, the healthcare provider Fraser Health Authority has partnered with Verto Health to create a digital twin model of two million patients. This groundbreaking initiative, termed a "digital front door," allows patients to easily access services, book appointments, and obtain information through a virtual assistant named Fraser. This system streamlines hospital processes and optimizes bed capacity, enhancing clinicians' productivity and overall patient care. Verto’s AI system is designed to efficiently analyze extensive patient histories, summarizing crucial data to support medical decisions.

In the realm of oncology, Altis Labs, another Toronto startup, is leveraging digital twin technology to expedite the drug development process. Developing cancer treatments is notoriously expensive and time-consuming, often exceeding $2 billion and taking over a decade. Altis aims to mitigate late-stage trial failures by using digital twins to identify issues early, thus enabling faster, more affordable trials. By employing advanced AI models, Altis generates nuanced metrics that predict patient outcomes beyond the traditional focus on tumor size, offering a richer understanding of disease progression and potential survival rates.

Digital twins also extend to broader social applications, as demonstrated by RUNWITHIT Synthetics, which creates geographic replicas to assess community resilience to challenges like extreme weather. For example, in Tennessee, a digital model was used to analyze the impact of heat waves, facilitating resource allocation to vulnerable areas and ensuring equitable service distribution.

However, as digital twin projects expand, concerns regarding equity and privacy arise. Experts emphasize the need for inclusive data collection practices to avoid perpetuating historical disparities in healthcare access. Marginalized populations often lack representation in data sets, leading to potential biases in virtual modeling. Moreover, there is a risk that excessive reliance on technology could overshadow human compassion and empathy in care delivery.

Healthcare organizations are urged to maintain a balance between technological innovation and the human elements that underpin care. Ensuring that digital twin systems prioritize user privacy is crucial, as highlighted by a recent U.S. report emphasizing ethical considerations throughout the development process. Initiatives like Verto, Altis, and RUNWITHIT implement strict data security measures to protect individual information.

In summary, digital twin technology holds immense promise for transforming healthcare by fostering personalized treatment approaches and improving systemic efficiency. However, to fully realize its benefits, the industry must address equity, compassion, and privacy, ensuring that these innovations genuinely enhance patient care. Efforts to streamline healthcare processes will be essential in securing access to quality services for all.
