Solutions such as revenue cycle management, clinical workflow optimisation, and patient engagement are seeing widespread adoption (Bain, 2024). Moreover, generative AI enhances manual customer support through multimodal capabilities, encompassing audio, text, and image processing (Deloitte, 2023). By harnessing AI-driven automation, these solutions streamline administrative workflows and enhance overall operational efficiency (Boston Consulting Group, 2023).


Furthermore, generative AI is driving the healthcare industry towards supply chain excellence by optimising logistics, inventory management, and distribution processes (Deloitte, 2023). Leading companies in this space, such as Doximity, Abridge, and DeepScribe, are spearheading the development of applications that automate critical processes (Boston Consulting Group, 2023).


II. Pharmaceutical Firms

Generative AI is revolutionising innovation in biopharma, particularly in the realms of molecular structure prediction and drug discovery.


a. Molecular Structure Prediction

Generative AI employs advanced techniques to produce customisable 3D models, allowing for precise visualisation and prediction of biomolecule structures (Deloitte, 2023). For instance, DeepMind's AlphaFold algorithm has made significant strides in predicting the three-dimensional structures of various proteins, including those crucial for the development of vaccines against the novel coronavirus (Google DeepMind, 2022).


b. Drug Discovery

In addition to structure prediction, generative AI accelerates drug discovery by integrating text, images, and customisable 3D elements, which enables simulating vast numbers of virtual molecules for rapid screening and optimising drug development (Deloitte, 2023). This intelligent molecular design helps accelerate the discovery of new drugs and improve existing drugs, reduces the time and resource investment in preclinical testing, and brings breakthroughs to drug research and development (Goyal, 2024). Platforms like Nvidia's BioNeMo are transforming drug development processes, reducing preclinical testing time and resources while facilitating breakthroughs in research and development (Powell, 2024). Partnering with Sanofi, BioMap's AI platform exemplifies the industry's shift towards optimising drug discovery processes (PricewaterhouseCoopers, 2023).


Despite its potential, generative AI in drug development faces challenges such as data quality and algorithm reliability (Bain, 2024). Real-world data acquisition emerges as a critical trend, shaping the future landscape of generative AI-driven biopharma (Deloitte, 2023).


III. Payers

Payers, encompassing insurance companies and welfare organisations, are pivotal stakeholders in the healthcare industry. In response to increasing demands for personalised and convenient services from consumers, payers are embracing generative AI, particularly Large Language Models, to enhance operational efficiency and service quality in different service stages (McKinsey, 2023).
