More than 1,300 operations were performed by orthopedic traumatologists at the National Medical Research Center for Traumatology and Orthopedics named after N. N. Priorov (CITO) with the participation of a voice AI agent from the T1 IT holding.
The effectiveness of surgical checklists has been confirmed by scientific research. According to the results of a large international study*, the use of a surgical checklist can reduce the complication rate from 11% to 7%, and the mortality rate from 1.5% to 0.8%.
“Voice assistant for surgical safety”, developed by specialists from the T1 IT holding based on speech recognition technology and large language models, is integrated into the MIS “Parus”** and works in conjunction with specialized equipment for operating rooms – computer stands, microphones. The project started in June 2025 with the equipping of one operating room, and by mid-2026 it was scaled up to include four operating rooms.
The key objective of the development is to minimize the risk of complications during surgery by standardizing communication within the operating team and automating safety checklists through voice completion.
Previously, safety checklists were often filled in manually after the fact from memory, after the operation was completed, which reduced the accuracy of the entered data and the possibility of their subsequent analysis. Now the process is automated: the documents are filled out by an AI assistant that processes voice information from the operating team.
After the patient is delivered to the operating room, his bracelet is scanned, his card is opened in the SAIL system, and the voice assistant is launched. The system consistently guides the surgical team through all stages of the operation. The AI agent asks questions, clarifies the answers, and records the data itself. Upon completion, the information is automatically stored in the MIS and used to analyze compliance with surgical safety procedures.
The use of a voice AI assistant to fill out a checklist corresponds to the national project to create a unified digital healthcare loop. The plans of CITO named after. N.N. Priorov – replication of the solution to 22 operating rooms.
“The idea of the checklist is to stop at the key stages of the operation and have the whole team – surgeon, anesthesiologist, operating room nurse – check the critical points. This makes it possible to reduce the number of preventable errors and complications by improving communication and team coordination. At the same time, it takes about six minutes to fill out all three blocks of the checklist by voice,” explained Elena Kleymenova, Deputy Director for Quality of Medical Care and IT of the National Medical Research Center of Traumatology and Orthopedics named after. N. N. Priorova (CITO).
“Artificial intelligence technologies have made it possible to create not just a recording tool, but a full-fledged decision support system based on serious analytics. The accumulated data is visualized on dashboards and can be used for internal control of the work of a medical institution,” said Sergey Golitsyn, head of T1 AI (T1 IT holding).
