Under a Fifth of PCPs Exchange Data Online With Public Health

Only 18% of primary care physicians (PCPs) and 12% of all doctors exchanged data electronically with public health agencies in 2019, according to a new report from the Office of the National Coordinator for Health IT (ONC).

However, the percentage of PCPs who exchanged data electronically with public health agencies was five percentage points higher in 2019 than in 2018, the report noted. Moreover, it is likely that the frequency of electronic reporting to these agencies has increased since 2019 because of COVID-19.

“The [electronic reporting] has absolutely improved,” Keith Kelley, chief operating officer of the Indiana Health Information Exchange (IHIE), told Medscape Medical News. He attributed this change to the pandemic.

The survey data in the report doesn’t show how many practices exchanged data with state and local public health agencies (PHAs) through manual processes such as paper-based data sharing, phone calls, emails, and faxes, an ONC blog post noted. Recent studies show that these are the primary conduits for sending and receiving data between healthcare providers and PHAs, the post said.

“Low rates of electronic reporting may be due, in part, to variation in jurisdictional requirements for electronic reporting (i.e., most jurisdictions allow paper or electronic reporting), as well as PHAs’ capacity to electronically receive standardized data from office-based physicians,” according to ONC.

About 29% of the doctors responding to the survey said that their practices didn’t exchange any patient information electronically. Another quarter of the respondents said they didn’t know whether their practices reported public health data electronically.

In Kelley’s experience, most independent practices report this kind of data using faxes or online portals of public health agencies. In contrast, he said, public health data from physicians employed by health systems is more likely reported electronically.

Nationwide, however, the report found little difference in the percentages of independent and employed physicians who were online with PHAs.

Differences Among Primary Care Specialties

Only 12% of general practitioners and family physicians shared data electronically with PHAs in 2019, the reported noted. In contrast, 24% of general internists and 26% of pediatricians exchanged data online with PHAs.

Similarly, 44% of PCPs electronically searched for vaccination or immunization history information from sources outside their practice or system. But only 41% of general practitioners and family physicians did so, compared with 53% of internists and 51% of pediatricians.

Much of this difference can be explained by the fact that more general practitioners and family physicians than internists or pediatricians practice in rural and other underserved areas, according to Steven E. Waldren, MD, vice president and chief medical information officer of the American Academy of Family Physicians.

Underserved areas, he told Medscape, frequently have “unique barriers to interoperable data exchange, like broadband internet access and social determinants of health. Additional investments are needed to improve equitable access to broadband connectivity so family physicians can participate in electronic exchanges of health information with public health agencies.”

PCPs who reported the ability to electronically search or query for patient health information from outside sources were three times more likely to exchange information electronically with PHAs than those who didn’t have this search capability. PCPs who reported the ability to integrate patient health information into their EHRs were twice as likely to search for immunization data as those who didn’t have this capability, and 81% of the physicians who could integrate outside information searched for this data.

The percentage of PCPs who looked for public health data outside their practices was more than twice as high as the portion of primary care doctors who exchanged data electronically with PHAs. Asked why so many physicians sought this information from sources other than their county or state health departments, Kelley said it had to do with the completeness and quality of the data available from PHAs.

“In Indiana, providers are required to submit data on childhood immunizations, but not adult vaccinations. Consequently, the state immunization database has holes in it,” he noted. “Even with the childhood vaccinations, compliance is not 100%. So when a parent asks a doctor for a record of their son’s or daughter’s immunizations, and the physician queries the state public health database, and they’re not confident in the results they get back, they stop querying it.”

Among the physicians who reported electronically to PHAs, 90% submitted vaccination data, the report said. They less frequently reported electronically on cases of infection (45%), public health registry data (27%), or syndromic surveillance data (17%). Pediatricians reported the highest rates of exchanging immunization, case reporting, and syndromic surveillance data, while internists had the highest rates of exchanging public health registry data.

Practice Ownership, Size, and Type of EHR Are Factors

There was little relationship between practice size and the likelihood of electronic reporting to PHAs. For example, 17% of solo physicians said they did so, while just 12% of doctors in groups of more than 50 physicians reported that they did. And 17% of doctors in physician-owned practices electronically exchanged data with PHAs, just a couple of points less than for doctors in hospital-owned groups.

Physicians who used an EHR with a large market share had the highest rates of electronic exchange with PHAs and were also more likely to search for vaccination or immunization information from outside sources. One reason for this, suggested Kelley, is that the major EHRs have modules designed to exchange information with PHAs, but the EHRs typically used by independent practices tend to have less advanced interoperability features. Even if such an EHR can communicate electronically with a PHA, EHR vendors charge fees for these modules that many practices might find onerous.

The ONC report drew attention to the finding that a quarter of the respondents didn’t know whether their practices exchanged data electronically with PHAs. The authors surmised that these doctors were more likely to be in large practices and may not have been aware of electronic connections with outside entities. “Therefore, it is possible that reported rates underestimate rates of electronic exchange with public health.”

Because physicians employed by health systems “are usually on the same software platform as the hospital, the hospital typically takes care of that for the employed physicians,” Kelley noted. “So the reporting rate for employed physicians [in Indiana] is significantly higher than that for the independent practices.”

Health information exchanges such as IHIE can perform a vital function in helping to convey data from healthcare providers to public health agencies, he noted. Indiana gives hospitals the option of using IHIE for this function or reporting directly to the state health department online, but the majority use IHIE, he said.
