The AI healthcare revolution and what it means for medical communications
Blockbuster movies depict artificial intelligence (AI) as self-aware, sentient beings with a hunger for world domination. While this is still a far-fetched fantasy, AI is ever more present in our lives and looks set to transform healthcare too; Google Maps route predictions, Netflix movie suggestions and Amazon’s Alexa platform all rely on AI technology.
Evidence is mounting that medical research, payor decision-making, diagnostics and even the delivery of care could benefit from AI solutions. With an AI healthcare revolution on the horizon, it may be time for the medical communications industry to understand the implications of, and possibly even harness, AI technologies to better serve our clients.
AI in drug discovery and development
Though lagging behind other sectors, such as retail and social media, we are starting to see pharmaceutical companies implement AI strategies. For instance, machine learning (a form of AI) could accelerate drug discovery. Novartis has partnered with IBM’s machine learning platform ‘Watson’ to identify breast cancer drug targets using real-world data1. By increasing the efficiency of the drug discovery process, AI may be key in reversing the trend of rising research and development costs for new drugs2.
The drug development process could also benefit from machine learning technologies. The application of machine learning to computational modelling of chemical structures could reduce the economic and ethical costs of toxicity studies by alleviating the burden of, or even replacing, animal models3.
We are seeing an explosion of patient-facing AI solutions such as ‘Chatbot’ health assistants, with the potential to relieve the burden of medical triaging in primary care; and a good example of this is ‘GP at Hand,’ which was recently trialled by the NHS4. Chatbot technology mimics human conversation and is already being harnessed by medical communications agencies to modernise patient engagement. For example, Cohn & Wolfe developed ‘Tabatha’ – a Facebook-based Chatbot – as part of Boehringer Ingelheim’s ‘Think.Act.Breathe‘ (TAB) campaign, to encourage patients to act on their asthma symptoms5. A key benefit of this technology is that it can generate tangible metrics that illustrate how effective campaigns are at promoting behavioural change.
Another application of AI is in the automation of repetitive cognitive and decision-making tasks. The Hindsait6 platform, for example, applies predictive analytics and natural language processing (NLP) to patient data in order to provide scoring of clinical need, in accordance with clinical guidelines and regulatory requirements. This technology has the potential to improve the efficiency and reliability of payor decision-making.
Furthermore, in the secondary care setting, predictive analytics could improve patient outcomes by identifying inpatients who are most at risk of transfer to ICU7. We may also begin to see AI systems used in the automation of various pharmaceutical company processes, including compliance documentation and social media monitoring8.
Diagnostics and patient monitoring
AI is also showing potential in the areas of diagnostic techniques and patient monitoring. For instance, when supported by AI image-analysis technology, dermatologists have been shown to be more accurate at diagnosing melanomas9; similarly, the facial image-analysis framework ‘DeepGestalt’ has been shown to outperform clinicians in the identification of rare genetic disorders10.
Wearable patient-monitoring technologies such as the Apple Watch Series 4’s EKD (electrocardiogram)11 and Google’s blood glucose monitor ‘the Soli system’12 could lead to improved, more personalised patient care, as they enable the collection of considerably higher volumes of data than is possible by traditional medical consultation. Such quantities of patient data are likely to require interpretation by AI systems in order to be clinically useful.
Pharmaceutical companies could benefit from AI-based diagnostic and monitoring technologies through modernisation of treatment pathways and consequent optimisation of pharmaceutical intervention. As a result, there may be value in raising awareness of such technologies through medical education initiatives.
AI in med comms
From patient engagement to medical education, AI has the potential to impact the medical communications industry. However, the key will be in identifying which of our clients’ needs could be addressed by AI technology, whether it is financially viable to do so and how to implement these solutions. Armed with an understanding of how AI can be utilised, now may be the time for us to join, or possibly even lead, our clients into this exciting new paradigm of healthcare.
