After the pilot period, Garcia and the team issued a survey to the clinicians, asking them to report on their experience. They reported that the AI-generated drafts lightened the cognitive load of responding to patient messages and improved their feelings of work exhaustion despite objective findings that the drafts did not save the clinicians’ time. That’s still a win, Garcia said, as this tool is likely to have even broader applicability and impact as it evolves.
