Progress and Persistent Disparities in Patient Access to Electronic Health Information.

Importance: Patient access to electronic health information (EHI) available via online medical records and through patient portals has been shown to help individuals make informed health decisions, which are associated with better health outcomes. Objective: To assess progress in patient engagement with EHI and to identify racial or ethnic disparities in access to patient portals. Design, Setting, and Participants: This was a repeated cross-sectional study using data from the US Health Information National Trends Survey (HINTS), a nationally representative survey of US adults that tracks individuals' access and use of their health information. Six cycles of HINTS were included (2014, 2017-2020, 2022); data for the disparities analysis came from the 2022 HINTS. Data analyses were performed in April 2023. Main Outcomes and Measures: Patient reports of (1) being offered portal access by a health care provider (HCP); (2) being encouraged by the HCP to use the portal; (3) accessing their portal; and (4) using the portal for various purposes. Additional key measures included methods used to access portals and self-reported ease of understanding information contained in the online medical records or portals. Results: The total study population included 22 266 individuals (mean [SE] age, 49.9 [0.15] years) of whom 13 348 (54%) were female; 909 (5%) self-identified as Asian, 3523 (12%) as Black, 3178 (14%) as Hispanic, 13 555 (66%) as White, and 785 (3%) as another or more than 1 race. Nationally, patient portal access increased each year from 2014 through 2022, with a 46% increase observed between 2020 (n = 3319) and 2022 (n = 5437). However, in 2022, Black and Hispanic individuals reported being offered access to a portal by their HCP at significantly lower rates compared with White individuals (73% vs 81%; χ21 = 22.24; P < .001; and 62% vs 81%; χ21 = 135.57; P < .001, respectively) as well as accessing a patient portal at lower rates (60% vs 70%; χ21 = 23.80; P < .001; and 57% vs 70%; χ21 = 49.02; P < .001, respectively). Conclusions and Relevance: The findings of this repeated cross-sectional study of US adult respondents to the HINTS suggest that access to and engagement with patient portals increased significantly from 2014 through 2022, but racial and ethnic disparities in patient access persisted in 2022. However, there were no significant differences in use or understanding of information available in the online medical records among those who accessed them, which suggests that efforts to promote equitable opportunities to access EHI would likely be associated with increased patient access.
