Clinical reviewers frequently face the challenge of adapting to diverse data sources and formats. To address this issue, Evernorth has developed an innovative clinical support tool designed to facilitate rapid and efficient access to necessary information, irrespective of data structure or format. The development of this end-to-end integrated solution within a six-month timeframe required cross-functional team collaboration and the implementation of cutting-edge methodologies. Utilizing advanced natural language processing (NLP) techniques, large language models (LLMs), and a cloud-based architecture, the resulting system demonstrates high accuracy and reliability. This presentation will outline the core principles guiding the project, key insights gained, and the achieved outcomes.
