The COVID-19 pandemic exposed gaps in the nation’s public health infrastructure, including a need for increased electronic exchange of patient health information between health care providers and public health agencies (PHAs) (1). Physicians play a critical role in supporting public health surveillance by reporting to PHAs. While public health reporting often occurs through manual, paper-based processes, national efforts have focused on increasing electronic reporting to PHAs. Improving surveillance would also include increasing PHAs’ access to data on social and behavioral determinants of health that affect a person’s health outcomes and risks. These data are important to enhancing public health surveillance as they enable identification of populations in need of greater assistance, including those with comorbidities and other risk factors (2, 3). Using data from a nationally representative sample of physicians, this brief describes primary care and other office-based physicians’ electronic public health reporting and social and behavioral determinants of health data recording capabilities and how they varied by physician and practice characteristics. This analysis offers insights into physicians’ readiness to electronically support public health activities in the year prior to the pandemic; it does not report on physicians’ overall levels of public health reporting—which can occur through manual, paper-based methods—nor does it reflect recent levels of electronic public health reporting which may have improved during the pandemic.

Figure 5. Public health reporting and recording capabilities, by EHR developer market share.

The COVID-19 pandemic revealed significant gaps in the public health infrastructure needed to support the electronic exchange of public health data among health care providers and PHAs (6). In 2019, only 12 percent of physicians nationally reported electronically exchanging patient health information with PHAs. However, electronic exchange capabilities were higher among primary care physicians (18%) particularly among those working in internal medicine (24%) and pediatrics (26%). Encouragingly, overall rates of public health reporting among physicians have risen over time, with rates among primary care physicians increasing 5 percentage points between 2018 and 2019 (Appendix Figure A1 and Table A2).
While our findings indicate that most office-based physicians were not engaged in electronic public health reporting in the year prior to the pandemic, a larger share of physicians may have been reporting to PHAs using manual methods. Our results do not reflect overall reporting rates to PHAs, nor do they distinguish between the proportion of reporting performed manually versus electronically. However, recent studies demonstrate that provider-based public health reporting occurs primarily through manual processes (e.g., paper-based data sharing, phone calls, e-mail, and fax) and rates of electronic exchange between clinicians and PHAs remain low (7-10). 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. For instance, while most providers collect immunization and case reporting information in their EHRs at the point of care, information is often not automatically shared electronically with PHAs due to varying data standards and a lack of integration between EHRs and public health surveillance systems (10).
Our findings also indicate a potential gap in physician’s awareness of their role in reporting timely and accurate data to support key public health activities. A quarter of office-based physicians nationally didn’t know whether their practice electronically exchanged data with PHAs. Physicians who didn’t know whether their practice exchanged health information with PHAs were more likely to be in larger practices and may not be aware of electronic connections with external entities. Therefore, it is possible that reported rates underestimate rates of electronic exchange with public health. As new data on physicians’ public health reporting capabilities become available, we intend to examine how public health reporting capabilities evolve over time. This will provide greater insight into whether the pandemic has changed physicians’ awareness and exchange practices with PHAs.
Immunization data was the most common type of data exchanged (sent or received) between primary care physicians and PHAs. In 2019, 100 percent of pediatric primary care physicians who exchanged patient health information with PHAs sent or received immunization data compared to 89% of general/family practice and 82% of internal medicine primary care physicians. Nearly half of primary care physicians who exchanged information with PHAs sent or received case reporting information (45%), however, other types of public health data—such as public health registry and syndromic surveillance data (which are primarily sent to PHAs from hospitals)—were exchanged at much lower rates. Additionally, 44% of primary care physicians electronically searched (or queried) for immunization history from other providers.
More than two-thirds of physicians nationally (68%) reported using a computerized system to electronically record both social and behavioral determinants of health data (e.g., employment, income, housing, or education; alcohol and tobacco use, physical activity) that could help support public health activities. Encouragingly, we found that physicians electronically engaging with PHAs (either via exchange or querying public health data), electronically recorded social and behavioral determinants of health data at significantly higher rates compared to respondents who did not engage in these activities. This suggests that physicians who electronically exchanged with PHAs may be more likely to possess information that could facilitate better care coordination and help support critical public health surveillance and reporting.
The COVID-19 pandemic revealed significant gaps in health care and health equity in our society and have highlighted the link between socio-behavioral factors and public health. Our analysis of 2019 NEHRS data suggest that social and behavioral determinants of health data may be available for public health reporting; however, the survey did not specify which types of social or behavioral data elements were recorded electronically, nor did it capture whether data were recorded in a standardized format or included as free text within clinical notes which would limit the ability for the data to be exchanged electronically (11-15).
Major efforts supported by ONC are underway to support the standardization and exchange of social determinants of health (SDOH) data including work done by The Gravity Project to develop standards for SDOH data and the recent addition of SDOH data elements to the USCDI version 2. Leveraging existing work in this area, ONC recently awarded a cooperative agreement to Health Level 7 (HL7) to address gaps in the current health IT environment by advancing standards for SDOH and public health that can help support the treatment and care of patients affected by COVID-19 and other public health threats. The advancement and uptake of SDOH standards in EHRs will enable the exchange of these data to support public health activities and advance health equity.
To ensure that health care providers are equipped to support critical public health activities, there are numerous HHS efforts aimed at improving the flow of information between health care providers and PHAs. To further advance standards that make it easier to exchange data between PHAs and health care providers, the USCDI+ initiative will support the identification and establishment of public health specific datasets that will operate as extensions to the existing USCDI. This should allow for a more tailored approach to support data exchange for public health. Additionally, ONC’s certified health IT supports electronic case reporting applications, such as eCR Now, that transmit data to PHAs using HL7 Fast Healthcare Interoperability Resources (FHIR®). ONC is also supporting efforts to enhance data aggregation, integration, and quality improvement services provided by health information exchange organizations (HIEs) through the Strengthening the Technical Advancement and Readiness of Public Health via Information Exchange Program (STAR HIE Program). This initiative supports the use of HIE infrastructure to facilitate public health reporting as well as identify and support communities disproportionately impacted by the pandemic.
To increase public health reporting among physicians, CMS has proposed a new requirement that eligible clinicians participating in the Promoting Interoperability performance category of the Merit-Based Payment System report on program measures related to immunization and electronic case reporting. The CDC’s ongoing Data Modernization Initiative aims to improve data sharing and public health data system interoperability through the adoption of common standards and by reducing burden on clinicians and other frontline workers that report to public health. In support of President Biden’s Executive Order (EO) on Ensuring a Data-Driven Response to COVID-19 and Future High-Consequence Public Health Threats, the Public Health Data Systems Task Force helped inform ONC and CDC’s response to Section 3 of the EO by identifying technical gaps in the current U.S. public health infrastructure and characteristics of an optimal future state for public health data systems. Insights from health care providers, PHAs, and other key stakeholders will be leveraged to identify specific recommendations to ensure public health data systems are equipped to support future high-consequence public health threats. Ultimately, efforts to standardize the collection and exchange of data for public health, as well as encourage and improve the use of methods and systems that make it easier for health care providers and PHAs to exchange data will help support key public health activities during the ongoing pandemic and in future public health emergencies.

Data are from the 2019 National Electronic Health Records Survey (NEHRS). The NEHRS is an annual survey of office-based physicians conducted by the Centers for Disease Control and Prevention’s National Center for Health Statistics. Physicians included in this survey provide direct patient care in office-based practices and community health centers; excluded are those who do not provide direct patient care (radiologists, anesthesiologists, and pathologists).
Among 10,302 total respondents to the survey, 2,280 met the necessary inclusion criteria, of which 1,524 completed all survey items – yielding a response rate of 67% among eligible respondents. Adjustments were made to account for non-response among physicians whose eligibility could not be determined and for those who did not participate in the survey. Responses for the 1,524 records included in the final 2019 NEHRS were weighted to reflect national estimates for approximately 301,603 office-based physicians in the U.S.
Additional survey documentation can be found on the NEHRS website.
