For the health care industry, AI-enabled solutions can provide immediate returns through cost reduction, help with new product development and lead to better consumer engagement. We explore how health care organisations can scale up their AI investments by pairing with a robust security and data governance strategy.
ARTIFICIAL intelligence (AI) is already delivering on making aspects of health care more efficient. Over time it will likely be essential to supporting clinical and other applications that result in more insightful and effective care and operations. AI has multiple use cases throughout health plan, pharmacy benefit manager (PBM) and health system enterprises today, and with more interoperable and secure data, it is likely to be a critical engine behind analytics, insights and the decision-making process. Enterprises that lean into adoption are likely to gain immediate returns through cost reduction and gain competitive advantage over the longer term as they use AI to transform their products and services to better engage with consumers.
Deloitte conducted the State of AI survey in late 2019 which featured questions around how organisations are adopting, benefitting from and managing AI technologies by industry. This survey was conducted before COVID-19 significantly impacted the United States. The survey found that:
The current pandemic overwhelmed health systems and exposed limitations in delivering care and reducing health care costs. The period from March 2020 saw an unprecedented shift to virtual health, fuelled by necessity and regulatory flexibility.1 The pandemic opened the aperture for digital technologies such as AI to solve problems and highlighted the importance of AI. Even though the survey was fielded before the public health crisis, some of the outcomes and challenges that health care organisations had in using AI prior to the pandemic will likely continue to be instructive as health systems, health plans and PBMs develop their new AI investment strategies.
Health systems were challenged by historic lower revenues due to nonurgent care and were forced to scale back during the pandemic. They can expect to gain advantage by using AI for applications to support cost savings as they transform.
Health plans and, in the longer-term, health systems, can use AI-enabled solutions to gain insights, develop new products and services and better engage with consumers. Health plans can also use AI to proactively detect and manage fraud, waste and abuse, resulting in recovered payments and cost avoidance, saving them millions and improving patient care.
This could well include an expansion of AI’s reach into clinical and back-office applications. Even as health care organisations step up their investments into data and analytics with AI, they should pair these with a robust security and data governance strategy.
AI is gaining traction in health care, starting with automating manual and other processes, and the number of use cases and sophistication in the use of the technology is growing. In our vision of the Future of Health, we view radically interoperable data as central to the promise of more consumer-focussed, prevention-oriented care and analytics as critical to using the vast data that will be generated by ubiquitous sources. AI has already become embedded into analytics and is likely to become even more so in the future.
AI uses algorithms and machine learning (ML) to analyse and interpret data, deliver personalised experiences and automate repetitive and expensive health care operations. These functions have the potential to augment the work of both operational and clinical staff in decision-making, reduce the time spent in administrative tasks and allow humans to focus on more challenging, interesting and impactful management and clinical work.
Today, health care organisations experience pervasive problems across their value chains, spanning every process on the continuum from care to cure. In the future, health care organisations that apply AI across every process from care to cure can improve the health and well-being of consumers. Deloitte’s Cognitive Care to Cure solution is an AI-powered, cloud-based, digital health care solution-as-a-service that can be applied across the health care value chain to improve operational efficiencies, reduce costs and support better health outcomes for consumers (figure 1). These are all on the same platform and can offer efficiency to organisations looking for multiple solutions. They are also available as individual services, allowing health care organisations to choose from a menu of offerings that meet their needs and strategy.
The term artificial intelligence is used for computer systems that perform human-like, mental tasks, such as visual perception, speech recognition and decision-making based on data patterns. According to Deloitte’s Taking AI to the next level article, the key attributes of AI systems are:
Between October and December 2019, Deloitte’s Centre for Technology, Media & Telecommunications surveyed 2,737 IT and line-of-business executives around the world to understand how organisations are adopting, benefiting from and managing AI technologies by industry. Deloitte’s Centre for Health Solutions analysed the responses from 120 executives in health care organisations to understand the current and anticipated investments, top priorities and AI risks and concerns related to health care organisations. Of these responses, 87 were from executives in US health care organisations while the remaining 33 were from regions including Australia, Canada, China, France, Germany, Japan and the Netherlands.
We also interviewed a leader in a large national health plan to include insights on current applications of AI in that organisation and what the future could hold.
Health systems and health plans are likely to emerge from the response to COVID-19 with a renewed focus on efficiency and affordability. The American Hospital Association estimates US hospital income losses to increase by US$120.5 billion from July through December 2020, bringing total losses to around US$323 billion this year.2 Although health plans have remained financially buoyant through 2020, they are watching for economic trends that may result in more of their enrollees getting coverage through Medicaid and health insurance exchanges, which tend to pay less than commercial employers. Solutions that will deliver savings and efficiency have never been more relevant and AI is embedded in many of these.
AI-based solutions can effectively streamline diagnostic and treatment processes by using large amounts of structured and unstructured medical data across institutions. This can aid physicians at hospital and health systems in clinical decision-making by providing them with real-time, data-driven insights that they can alter and implement based on their personal expertise (see sidebar, “Improving patient outcomes with AI”).
“Health plans are utilising the power of AI to make better predictions from data for external and internal stakeholders—proactively reaching out to consumers with information on disease progression and next best action for care and supporting physicians in clinical decision-making by arming them with the right insights.”
—Ashok Chennuru, Chief Data and Analytics Officer, Anthem Inc.
AI-powered solutions can assist in accurately scheduling and planning clinical staff rotation—a major challenge for health systems since the onset of the pandemic—by factoring in operational constraints such as the number of staff, availability, skills and specific equipment required (see sidebar, “Smart workforce management with AI”).
AI can also minimise patient risk by identifying medication errors that traditional rule-based clinical decision support systems are unable to detect, while also reducing alert fatigue and false positives—one of the reasons of physician burnout (see sidebar, “Minimising safety risks through medication error detection with ML”).
Israel-based MedAware's patient safety platform applies advanced ML algorithms and outlier detection mechanisms to identify and prevent medication-related errors and risks. The platform flags medications that conflict with the profile of the patient, physician, or institution. MedAware flagged 10,668 potential errors and adverse drug events in the records of 373,992 patients treated in the outpatient clinics of Massachusetts General and Brigham and Women’s Hospitals. In an analysis done on a random sample of 300 warnings generated by MedAware, 92% of the warnings were accurate based on data available, 79.7% of the warnings were clinically valid and 68.2% of the warnings would not have been flagged by existing decision support systems.6
The ability of AI to examine large amounts of information quickly can help hospital and health plan administrators optimise performance, increase productivity and improve resource utilisation, resulting in time and cost efficiencies. Additionally, AI-enabled solutions can speed up and strengthen the insight generation process by allowing the organisation to gain the holistic picture it needs to make data-driven decisions. Finally, AI can also deliver personalised experiences by facilitating conversations with patients through virtual assistants (see sidebar, “Optimising nonclinical operations with AI”).
According to the Journal of the American Medical Association (JAMA), approximately 25% of US spending on health care is wasteful, translating into an estimated US$760–935 billion wasted every year.8 However, AI-based analytics present the opportunity for health plan companies to detect and reduce improper billing practises for streamlined member billing. Additionally, PBMs can use AI to integrate and assess patient medical information to resolve issues in real time, leading to improved patient care experience. AI can also help to effectively and proactively identify potential fraud, waste and abuse (see sidebar, “Realising efficiency through fraud, waste and abuse [FWA] detection and prevention”).
Interest in AI in health care has surged since last year as provider and payer organisations seek to tap the potential benefits offered by data-driven analysis and deep neural networks.10 Clinicians are more open to digital technologies, since they experienced firsthand during the pandemic how these technologies augmented their skills in areas including surgery and diagnosis. As these organisations begin to scale up their AI applications based on their short- and long-term priorities, they should be mindful of risks during implementation.
Surveyed leaders agreed that health care organisations are investing, but the investments vary widely. Seventy-five per cent of large organisations (annual income of over US$10 billion) invested over US$50 million in AI projects/technologies, while approximately 95% of mid-sized organisations (annual income between US$5–10 billion) mostly invested less than US$50 million (figure 3). Seventy-three per cent of these health care organisations also expect their investments in AI to increase in the next fiscal year.11 Additionally, most of the surveyed leaders believe that the actual payback period for their organisation’s AI investments is in line with their expectations.12
AI has the potential to create new efficiencies in administrative processes and provide a precise and faster diagnosis and treatment plan for each patient, resulting in reduced length of stay, fewer subsequent readmissions and reduced costs.
When asked about the outcomes organisations are trying to achieve through AI, surveyed health care leaders cited more efficient processes as their top priority (34%). Enhancing existing products and services (27%) and lowering costs (26%) are a distant second. None of these organisations has achieved all outcomes to a great extent, but making processes more efficient comes the closest (43%) (see figure 4).
Another Deloitte survey, conducted in February 2020 and with a focus on physicians, had similar findings. Seventy-three per cent of the surveyed physicians reported that saving time and resources is expected to be the No. 1 benefit of AI. Additionally, over 50% of surveyed physicians said they would increase their use and support of AI-driven solutions if they are shown to improve efficiency and quality.13
Survey respondents pointed to poor-quality data, siloed data systems, high initial costs of AI solutions with low return on investment and integrating AI into legacy systems as concerns.
Surveyed leaders indicate that the top challenges faced by their organisations include cost of systems (36%), integrating AI into the organisation (30%) and AI implementation, data and risk issues (28%) (see figure 5).14 When asked about ethical risks, they mentioned that they were most worried about safety concerns around AI-powered systems (28%).15 Additionally, findings from the 2020 Survey of US Physicians indicate that 69% of the physicians are concerned about who is liable when AI-driven solutions make a mistake.16
As investments in AI increase and AI-powered solutions become more widespread in health care settings, the industry should address the new set of challenges both from the data used—including cyber threats—and the potential for bias in the AI algorithms. The strategy should comply with regulations—including to assure patient privacy and other HIPAA requirements (figure 6).
AI algorithms present risks such as variability of output in patient diagnosis and treatment, data bias and traditional IT risks such as change management. Health care organisations should verify the integrity and accuracy of their AI algorithms by focussing on:
For health systems and health plans to achieve their business objectives, they should:
AI is delivering significant business benefits today—and its potential to shape the future of the health care industry is even greater. Health care organisations that are still in the experimental pilot phase stand to be left behind by payers and competitors.
“It is essential for health care organisations to understand how to automate processes by reimagining them. That’s where AI can help. The ‘digital-first, AI-first, insights-driven organisation’ mindset needs to be incorporated into every business unit of the enterprise with a focus on automation.”
—Ashok Chennuru, Chief Data and Analytics Officer, Anthem Inc.
For health systems: To prepare for the Future of Health, health systems should move from the experimental stage to having data and advanced AI as a core capability.
Health systems are currently under a lot of financial stress. For them, the short-term focus might be on investing in AI approaches that will help them achieve cost savings. Some examples of these are provider profiling (supply chain); fraud, risk and abuse detection and prevention; and automating health care operations.
Over the longer term, health systems can invest in more transformative AI applications to improve their competitive positioning, achieve profitable growth, engage consumers and deliver personalised customer experiences. Health systems should actively cultivate their relationships with AI start-ups, technology and professional services firms and academia, and consider taking a more active role in AI innovation. They should also encourage stakeholders, including physicians, clinical staff and administrative staff to strive to be champions and promote an AI-augmented workforce.
For health plans: Some health plans are already investing deeply in data and AI-based analytics. The focus should be to use AI to improve health insurance cost-efficiency, consumer engagement, insights for medical and organisational management and client outcomes, to complement the company’s overall positioning and strategy.
For PBMs: PBMs need to focus on determining and improving communication channels with health plans and use AI to optimise staffing and distribution activities. They should invest in AI to enable proactive management resulting in effective savings programmes and pharmacy programmes designed to improve the patient journey.
As all health care organisations figure out how to scale up AI-led innovations, they also should manage AI’s unique risks. Deloitte’s Trustworthy AI framework can help health care organisations identify and manage AI risks effectively to enable faster and more consistent adoption of AI.
