Participants were recruited from a convenience sample within the Patient Engaged Research Center (PERC) at Henry Ford Health to participate in a brief electronic survey. Any person with experience as a patient or caregiver could become a patient advisor within the PERC by completing an application, phone screen, and onboarding workshop. The role of a patient advisor includes, but is not limited to, providing feedback about ways to improve health care. A Qualtrics (Qualtrics International Inc) link for the survey was initially sent to all 406 patient advisors via email and a monthly electronic newsletter; 105 responded and completed the survey. Reminder emails were sent to patients approximately 2 weeks and 4 weeks after the initial email to remind those who had not yet completed the survey.

A total of 23 questions were developed by the research team regarding the patient portal (MyChart; Epic Systems Corporation), including questions about using the patient portal for research purposes and for requesting self-test kits for health. Participants were asked to provide information on their race (Black, White, American Indian or Alaska Native, or Native Hawaiian or Pacific Islander), age, marital status (married, widowed, divorced, separated, or never married), and gender (male, female, nonbinary, another gender, or prefer not to say).

Responses to questions regarding reading information about health conditions on MyChart, answering screening questions on MyChart, and whether participants would likely participate in research if contacted via MyChart were measured on a 5-point Likert scale (extremely likely to extremely unlikely). Participants were asked if they had ever heard of preexposure prophylaxis (yes, no, or unsure) and which method of HIV testing they would prefer (at the doctor’s office, taking a home-based test on their own, or not wanting or needing an HIV test). Participants were also asked how they access MyChart, which health topics (diabetes, blood pressure, HIV, drug use, alcohol use, tobacco use, cancer, cholesterol, depression, stress, anxiety, physical activity, diet, sleep, asthma, use of seat belts, immunizations, and sexual history) they would be willing to answer questions about in MyChart, and which self-test kits (colon cancer, COVID-19, HIV, sexually transmitted infections, allergies, cholesterol, influenza, urinary tract infections, alcohol use, and illicit drug use) they would be interested in receiving if they were provided free of charge.

All data were exported, cleaned, and uploaded into SPSS (IBM Corp). Frequencies and descriptive statistics were generated. Chi-square tests were run to examine whether significant differences existed among demographic variables.

The PERC is covered by an overarching institutional review board (IRB) approval at Henry Ford Health (IRB#16766) for patient advisors to fill out surveys and provide preliminary feedback. This study was covered under a blanket IRB approval for research conducted among PERC patient advisors and was considered preparatory to research; participants did not need to sign a consent form. All study data were deidentified. Anyone who completed the survey and indicated interest was entered into a raffle for three US $75 gift cards.

Participants were on average 57 (SD 14.35) years old (Table 1). Most identified as White (69/105, 65.7%) and female (80/105, 76.2%). Over half were married (60/105, 57.1%). For all results presented, there were no significant differences in responses by gender or race (all P values were >.05). All participant characteristics can be found in Table 1.

Almost all participants had accessed MyChart (102/105, 97.1%), with the majority accessing it at least once per month (44/102, 43.1%). There were various reasons why patients used MyChart, and patients reported various methods of accessing MyChart (Table 2).

Participants were likely to participate in different types of research if they were contacted by researchers in MyChart, including answering surveys, watching videos, and completing health assessments. They were also willing to answer questions to assess their risk for health conditions, including diabetes, HIV, and substance use (Table 3).

When asked what self-test kits they would be willing to receive if free of charge, participants indicated interest in several health conditions (Table 4).

Electronic health records and their patient portals, such as MyChart, have become increasingly common. We found that patients overwhelmingly use MyChart and are willing to use it to answer risk assessments, participate in research, watch videos, read health information, and complete surveys.

Importantly, we found no significant demographic differences in having used MyChart, accessing MyChart, completing activities within MyChart, and being willing to use MyChart for research purposes (all P values were >.05). The majority of our participants (38/98, 38.8%) were willing to not only be contacted to participate in research via the portal but also complete research-related activities, such as taking risk assessments (87/105, 82.9%) and viewing videos (86/105, 81.9%) in the portal. The lack of significant results in this study is in contrast to previous research. Other research has found differences in patient portal use based on demographic factors [15-17]. However, those studies were almost exclusively conducted before the COVID-19 pandemic. As Mai and colleagues [14] found, COVID-19 may be leading to a shrinking of the racial digital divide, as access and use of portal functionalities have expanded among racial minority groups. Patient portals may be tools for reaching large numbers of patients [18] for research purposes while potentially increasing access to research participation for women [19] and racial minority groups [14], who have historically not been equally represented in research. Future research should examine if research recruitment via patient portals can enroll participants who align with the demographic makeup of the health care system.

Participants in our research were generally willing to complete risk assessments via the patient portal and receive self-test kits, including those for stigmatized topics like HIV and substance use. In a similar fashion, a scoping meta-analysis by Gnambs and Kasper [20] found that individuals are more likely to disclose sensitive behaviors in computer-assisted surveys. Future research should examine whether answering questions about stigmatized topics in patient portals results in increased patient–health care professional communication or preventive care regarding those topics. Self-testing for HIV and substance use is important, as individuals who may not seek a health care professional for testing may be more comfortable or willing to test on their own [21,22]. As the TakeMeHome project found [23], providing HIV self-test kits gives options to people who may not be able or willing to test otherwise. Future research should examine if offering patients HIV self-test kits via the patient portal increases HIV testing in health care systems.

There are some limitations to this research. First, this study occurred with patients who were part of the PERC. Patients who participate in activities with the PERC may be different from the health care system patient population overall. For example, they are more likely to participate in research because they are already part of a research center and are more engaged with the health care system. Second, participants in this research were more likely to be female than male. Female individuals, compared to male individuals, have been found to be more likely to use patient portals [24]. The results may have been different if more male individuals participated. Finally, the survey for this research was distributed electronically. It may be that people who participate in web-based surveys are more likely to feel comfortable doing health-related activities electronically.

Patient portals allow patients to both have access to their electronic health information and interact with the health care system. They are becoming increasingly more common for clinical communication, but as we found, they can also be used for research recruitment and sending research-related information. Patients generally prefer to hear about research studies via portals and are willing to use them to answer risk assessments, read about health information, and complete other clinical tasks. Furthermore, patients would be interested in receiving self-test kits for various health conditions, including those for sensitive health conditions such as HIV. Patient portals are relatively novel tools for engaging patients in a variety of research and clinical activities, and patient portal use may be an ideal way to engage patients in research related to sensitive health conditions.
