Pros and cons of national directory
For all the money spent on maintaining provider directories, consumers don’t use them very much. According to a 2021 Press Ganey survey, fewer than 5% of consumers seeking a primary care doctor get their information from an insurer or a benefits manager. About half search the internet first, and 24% seek a referral from a physician.
A national provider directory would be useful only if it were done right, Mr. Zetter said. Citing the inaccuracy and incompleteness of health plan directories, he said it was likely that a national directory would have similar problems. Data entered by practice staff would have to be automatically validated, perhaps through use of some kind of AI algorithm.
Effect on coordination of care
Mr. Zetter doubts the directory could improve care coordination, because primary care doctors usually refer patients to specialists they already know.
But Julia Adler-Milstein, PhD, professor of medicine and director of the Center for Clinical Informatics at the University of California, San Francisco, said that a national directory could improve communications among providers when patients select specialists outside of their primary care physician’s referral network.
“Especially if it’s not an established referral relationship, that’s where a national directory would be helpful, not only to locate the physicians but also to understand their preferences in how they’d like to receive information,” she said in an interview.
Dr. Adler-Milstein worries less than Mr. Zetter does about the challenge of ensuring the accuracy of data in the directory. She pointed out that the National Plan and Provider Enumeration System, which includes the NPI registry, has done a good job of validating provider name, address, and specialty information.
Dr. Adler-Milstein is more concerned about whether the proposed directory would address physician preferences as to how they wish to receive information. For example, while some physicians may prefer to be contacted directly, others may prefer or are required to communicate through their practices or health systems.
Efficiency in data exchange
The API used by the proposed directory would be based on the Fast Health Interoperability Resources standard that all electronic health record vendors must now include in their products. That raises the question of whether communications using contact information from the directory would be sent through a secure email system or through integrated EHR systems, Dr. Adler-Milstein said.
“I’m not sure whether the directory could support that [integration],” she said. “If it focuses on the concept of secure email exchange, that’s a relatively inefficient way of doing it,” because providers want clinical messages to pop up in their EHR workflow rather than their inboxes.
Nevertheless, Dr. Milstein-Adler added, the directory “would clearly take a lot of today’s manual work out of the system. I think organizations like UCSF would be very motivated to support the directory, knowing that people were going to a single source to find the updated information, including preferences in how we’d like people to communicate with us. There would be a lot of efficiency reasons for organizations to use this national directory.”
