Beth Israel Lahey Health integrated an AI-powered internal chatbot called ChatPPGD that lets clinical staff search more than 3,800 care guidance documents by asking questions in plain language. The tool is used internally by attending staff and fields over 800 queries per week.

ChatPPGD was built by BILH's Innovation Lab using Microsoft Azure OpenAI Service, Azure AI Search, and Azure AI Document Intelligence. Staff type natural-language questions and receive answers drawn from policies, procedures, guidelines, and directives, with references to the source documents and medical citations included. The system has shown 98% accuracy in document responses. The Microsoft customer story describing this deployment was published in February 2025.
