Abstract: The present disclosure relates to generating a structured representation, particularly a summary, for a given subject by leveraging one or more generative artificial intelligence (GenAI) models based on one or more unstructured portions of electronic health record data of the subject. The techniques, as disclosed herein, may utilize a long record application programmable interface (API) to retrieve and process the one or more unstructured portions of electronic health record data of the subject into a semi-structured format. The disclosed techniques further utilize the one or more GenAI models to generate a prompt based on the semi-structured format, extract relevant data elements based on the prompt, and transform the data elements into a strategically reduced summary. The generated summary may assist users in making quick, informed decisions while reducing the need for exhaustive manual chart reviews of the subject.
