There is increasing interest in patient engagement via consumer-facing digital health tools such as patient portals that enable online access to medical records [1-3]. Federal policies such as the Electronic Health Record Incentive Program [4] and the Office of the National Coordinator for Health Information Technology’s Cures Act Final Rule [5] have been instrumental in advancing patient access to electronic health information (EHI). Despite growth in patient portal access [6], there is variation in the use of features [7] and a limited understanding of desired features and data needs. This study contributes to the literature by examining the use and interest in available portal features and identifying desired features and unmet data needs.

The participants (N=523) included were adults (aged >18 years), and most were current portal users (n=465, 88.9%). Portal users were White (n=375, 80.6%), non-Hispanic (n=414, 89%), female (n=325, 69.9%), and married (n=233, 50.1%). Most participants had a college or postgraduate education (n=339, 72.9%), resided in a suburban/urban area (n=408, 87.7%), and lived comfortably on their present income (n=313, 67.3%).

Of the 465 portal users, close to two-thirds (n=283, 60.9%) accessed their patient portal more than five times in the past 12 months, indicating frequent use. Notably, the portal nonusers (n=58, 11.1% of the 523 participants) had zero logins, and the reasons noted were lack of portal access, no perceived need, discomfort with computers, privacy/security concerns, and combined reasons, highlighting diverse factors influencing utilization.

For patients who accessed their portal at least once in the past 12 months, Table 1 shows that the frequently used features were viewing lab results (n=431, 92.7%) and visit information (n=412, 88.6%). The frequent features of interest but that are not currently used were pulling information from the state immunization registry into their portal (n=283, 60.9%) and entering vaccination information (n=274, 58.9%).

Table 2 displays the responses for desired portal features, with the most common being the ability to share genetic testing information with providers (n=343, 73.8%) and access to test results before providers review them (n=341, 73.3%). The most common data needs were data to be explained more clearly (n=157, 33.8%) and the need for more data from providers (n=135, 29%).

The patient-centered care movement has expanded efforts to increase consumer engagement with EHI via patient portals and other digital health tools. In 2023, the most utilized portal features were viewing laboratory results and accessing visit information, indicating the features’ importance to users. However, features such as pulling vaccination data from state registries and medical record downloads, despite being of interest, were underutilized. About half of the respondents noted that they were interested in accessing EHI via third-party apps and matching their profile to potential research studies but had not used these features. Further, certain features such as having immediate access to test results and accessing EHI via third-party apps should be available to all patients due to the Cures Act Final Rule [5], suggesting a potential lack of awareness of certain functionalities. Together, these findings indicate opportunities to increase outreach to patients and educate both patients and providers on available features. Finally, this research provides insights into future data and accessibility needs.

This study demonstrates the importance of specific portal features and ongoing data needs. While these findings may not be generalizable to the US population, they provide important insights into the current state of portal use and the needs of a state’s population. Future research should replicate this study at the national level and in medically underserved communities to better understand diverse needs, as well as identify desired features that are not currently available in patient portals.

In conclusion, in 2023, based on a sample from one state’s population, most participants used patient portals, but the use of the 22 functions varied widely. This helps understand the demand for portal features and informs portal design. The increasing use of patient portals underscores the importance of elucidating data needs across a broad range of users, implementing desired features to increase patient engagement and ultimately achieve better health outcomes [9,10].
