HCA Healthcare, the largest for-profit hospital chain in the United States, is planning to expand the use of an artificial intelligence (AI) tool to document doctor-patient interactions in its emergency rooms (ERs). The tool, developed by medical documentation company Augmedix, has been piloted at several ER departments within the HCA network for nearly a year. According to Augmedix CEO Manny Krakaris, the AI tool’s affordability was a key factor in HCA’s decision to expand its use. HCA has confirmed its plans to roll out the tool to more hospitals but has not provided a specific timeline.
