Graham Walker, head of AI at MDCalc, said the company sees the tool as an accelerator for clinical generative AI. “We can take away some of the challenges and risks and problems with the technology so that physicians can feel more confident in using it,” he said. CrossCover takes an approach that contradicts that of medical AI tools from OpenEvidence, Abridge, and electronic health record company Epic, which are trying to incorporate an ever-widening repertoire of patient, provider, and payer information into their recommendations. Rather than requiring clinicians to register with their national identification numbers or trying to mitigate risk by brokering privacy agreements that allow clinicians to enter protected patient health information, MDCalc’s tool focuses on stripping out those types of information from clinicians’ queries.
