See <a href=\"#appendix-1\">Appendix Table A1<\/a> for Survey Questions and <a href=\"#appendix-3\">Appendix Table A3<\/a> for individual primary care sub-specialty estimates.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-summary\">Summary<\/h2>\n\n\n\n<p>Physician access to IIS data via their EHR or IIS portal outside the EHR enables quick and easy access to a patient\u2019s full immunization history, helps keep track of a patient\u2019s immunization status, and provides access to broader population data that can aid in clinical decision-making (4). Such access has been shown to improve vaccination rates, especially when used in tandem with clinical decision support tools integrated with the EHR to prompt physicians or office staff when a patient\u2019s vaccinations are due (5,6). EHR-IIS connectivity is particularly important as it eliminates the burden of signing into a separate portal to access immunization data and helps ensure that patient immunization records are accurate and complete (7).<\/p>\n\n\n\n<p>In 2022, more than half of PCPs (58%) reported satisfaction with their electronic access to external immunization information in their EHR or portal outside the EHR. However, only 21% were \u201cvery\u201d satisfied and more than one-third of PCPs (36%) reported being \u201cnot at all\u201d satisfied with their electronic access to this information. An analysis of these same questions in the 2022 American Board of Family Medicine (ABFM) Continuous Certification Questionnaire (CCQ) found similar levels of satisfaction among family medicine physicians (see&nbsp;<a href=\"#appendix-4\">Appendix Table A4<\/a>). Overall satisfaction was highest among PCPs who viewed immunization data in their EHR (75%), followed by those who view immunization data via a portal outside the EHR (62%). Taken together, these findings suggest improving EHR-IIS connectivity\u2014which would enable physicians to view immunization data in their EHR rather than an outside portal\u2014would likely increase physician satisfaction with access to external immunization information. About 10% of PCPs do not have any access to immunization information from outside organizations but would like some type of access.<\/p>\n\n\n\n<p>The share of PCPs who viewed immunization data from outside organizations in their EHR (41% overall) varied by practice characteristics. For instance, PCPs practicing in an integrated delivery system, HMO, health system or other prepaid practice (58%), as well as those in an academic health center or faculty practice (47%), reported the highest rates of viewing outside immunization data in their EHR compared to other practice settings. Further, PCPs working in larger practices and those participating in value-based care had higher rates of viewing external immunization data in their EHR (41 to 47% and 45%, respectively) compared to those working in smaller practices and not participating in value-based care. PCPs using Epic as their primary EHR vendor reported using their EHR to view immunization data from outside organizations at significantly higher rates (58%) than PCPs using other EHR vendors, including other leading vendors, Cerner (37%) and eClinicalWorks (31%). Reported rates of using an EHR to view immunization data from outside organizations varied regionally which may be due, in part, to regional differences in EHR vendor market share (see&nbsp;<a href=\"#appendix-5\">Appendix Table A5<\/a>). For instance, PCPs in the Southeast and Southwest regions had significantly lower rates of using Epic\u2014the leading EHR vendor by market share\u2014who enables IIS-EHR connectivity. Regional differences may also reflect state-level variation in EHR vendor or IIS capabilities that we were unable to examine due to small samples in certain states.&nbsp;&nbsp;<\/p>\n\n\n\n<p>In 2022, about three-quarters of PCPs who viewed immunization data in their EHR indicated they were aware their primary outpatient EHR was capable of electronically accessing immunization data from (77%) and reporting data to (74%) their state\u2019s IIS. As a point of comparison, family medicine physicians who used an EHR to view immunization data reported similar capabilities of their EHR to access and report data to the IIS (<a href=\"#appendix-4\">Appendix Table A4<\/a>). However, rates varied by primary care sub-specialty with pediatricians having the greatest awareness of their EHR\u2019s capabilities to access data from or report data to their state\u2019s IIS (see&nbsp;<a href=\"#appendix-3\">Appendix Table A3<\/a>). This variation likely reflects differences in patient populations served as well as differences in reporting requirements for these populations (e.g., many states require reporting for child and adolescent vaccinations but not for adult populations). It is worth noting, however, that reported capabilities do not necessarily represent the actual capabilities of PCPs\u2019 EHRs to report data to or access data from a state IIS. About 1 in 5 physicians who viewed immunization data through their EHR reported being unaware of their EHR&#8217;s IIS access (16%) and reporting (23%) capabilities, with certain primary care sub-specialties having higher rates of unawareness. Further research comparing PCP-reported capabilities to actual EHR capabilities would provide more insight into these differences and potential drivers. Variation in state laws around IIS reporting and opt-in vs. opt-out policies for patients may also drive some of the observed differences in providers\u2019 awareness or use of their EHR\u2019s access and reporting capabilities.<\/p>\n\n\n\n<p>Several early and ongoing efforts have contributed to the current state of EHR-IIS connectivity, which requires providers to possess EHRs capable of connecting to IIS and for IIS to have the capacity to accept the connection and exchange immunization information.

Further, CDC\u2019s National Center for Immunization and Respiratory Diseases (NCIRD), in partnership with AIRA, developed the&nbsp;<a href=\"https:\/\/www.immregistries.org\/measurement-improvement\" target=\"_blank\" rel=\"noreferrer noopener external\" data-wpel-link=\"external\" class=\"wpel-processed wpel-icon-right\">Measurement and Improvement Initiative<i class=\"wpel-icon fa fa-external-link\" aria-hidden=\"true\"><\/i><\/a>&nbsp;to assess IIS alignment with&nbsp;<a href=\"https:\/\/www.cdc.gov\/iis\/functional-standards\/resource.html\" data-wpel-link=\"external\" target=\"_blank\" rel=\"external noopener noreferrer\" class=\"wpel-processed wpel-icon-right\">IIS Functional Standards<i class=\"wpel-icon fa fa-external-link\" aria-hidden=\"true\"><\/i><\/a>&nbsp;which describe the technology needed for IIS to support vaccination providers and other immunization stakeholders.<\/p>\n\n\n\n<p>Collectively, these efforts aim to encourage health IT developers to implement capabilities in their products to support immunization information exchange, incentivize immunization registry reporting among providers, and facilitate EHR-IIS connectivity. Our findings indicate that PCPs who used an EHR to view immunization data had the highest rates of satisfaction with their electronic access to immunization information and tended to report their EHR can access data from and report data to their state\u2019s IIS. These findings demonstrate the overall success of efforts to promote interoperability of immunization information but also highlight room for improving EHR-IIS connectivity and PCP satisfaction with their access to external immunization information.

Completion of the questionnaire is required as part of ABFM\u2019s recertification process and thus had a 100% response rate. To mitigate burden associated with the questionnaire, questions related to satisfaction with accessing external information electronically (N = 2,088) and questions related to accessing, reporting, and viewing immunization information (N = 2,066) were only asked to a subset of respondents.<\/figcaption><\/figure>\n\n\n\n<p id=\"appendix-5\" style=\"padding-top:var(--wp--preset--spacing--60)\"><strong>Appendix Table A5: <\/strong>Primary care physician EHR vendor market share, by region.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th class=\"has-text-align-center\" data-align=\"center\" scope=\"col\">Physician Characteristics<\/th><th scope=\"col\">Epic (N = 743)<\/th><th scope=\"col\">Other (N = 631)<\/th><\/tr><\/thead><tbody><tr><th class=\"has-text-align-left\" data-align=\"left\" scope=\"rowgroup\" colspan=\"3\">Region<\/th><\/tr><tr><th class=\"has-text-align-right\" data-align=\"right\" scope=\"row\">Midwest (N = 349) ref<\/th><td>42%<\/td><td>58%<\/td><\/tr><tr><th class=\"has-text-align-right\" data-align=\"right\" scope=\"row\">Northeast (N = 272)<\/th><td>45%<\/td><td>55%<\/td><\/tr><tr><th class=\"has-text-align-right\" data-align=\"right\" scope=\"row\">Southeast (N = 264)<\/th><td>30%*<\/td><td>70%*<\/td><\/tr><tr><th class=\"has-text-align-right\" data-align=\"right\" scope=\"row\">Southwest (N = 106)<\/th><td>25%*<\/td><td>75%*<\/td><\/tr><tr><th class=\"has-text-align-right\" data-align=\"right\" scope=\"row\">West (N = 384)<\/th><td>43%<\/td><td>57%<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">Source: 2022 National Physician Health Information Technology Survey.<br>Notes: *Significantly different from reference category (p&lt;0.05).
