Abstract
Background
Electronic health records are now the norm in US healthcare. Bidirectional patient portals allow frequent communication between patients and their healthcare team. Many studies have examined the importance of patient engagement and trust between patients and their healthcare team, typically in the context of face-to-face interactions. Little is known about how patient trust and engagement are built or enhanced through electronic communications. COVID-19 provided a unique time in history for this novel exploration.
Objective
Our objective was to learn how patients experience trust formation through electronic communication (patient messaging and video visits) with their healthcare team.
Design
Our research was guided by grounded theory methodology. Qualitative interviews were conducted between February and December 2020 with patients or their caregivers from an internal medicine clinic in Colorado.
Participants
Fifty-one participants were recruited by age group and gender to represent the clinic’s adult ambulatory care demographics. Seven were patients’ caregivers who were purposefully recruited. Average age was 53 with an educated, middle class, and largely white predominance in our eventual sample.
Approach
Thirty-minute semi-structured interviews were conducted using an interview guide informed by a validated physician-patient trust scale. Interviews were conducted by telephone, recorded via Zoom, and transcribed. Results were analyzed and coded in ATLAS.ti utilizing the constant comparative method, with two coders.
Key Results
Patients experienced enhanced trust in their healthcare team through electronic communications. Interpersonal and system factors contributed to trust formation. Promptness of reply was the most salient factor in trust formation with a majority desiring same day response.
Conclusions
Patients now rely on electronic communication with their healthcare team. Opportunities exist to leverage this to improve health outcomes. Important research in expanded demographic groups, along with ambulatory healthcare redesign, will be necessary to optimize benefits of electronic communication with patients and meet patient expectations.

INTRODUCTION
Electronic health record (EHR) adoption is now the norm in the USA. Over 90% of US physicians use an EHR in their outpatient clinical environments1. Many studies have examined the importance of patient engagement and trust between patients and their healthcare team2. These studies are historically based on face-to-face interactions. Little is known about trust formation within EHR portal communication.
Patient portals, defined as an application to “allow patients to interact with their health information and communicate with providers outside the traditional office visit”3, are an effective way to improve patient-provider communication as well as patient outcomes4, 5. A study by Lyles et al. is the first known US research on the potential power of patient portals to improve trust in care, specifically diabetes care1. Sieck et al. identified trust as one of three important psychological benefits of patient portal use for patients with chronic illness6.
Although patient portal technology provides opportunities for physicians to engage patients in their healthcare and potentially improve medical outcomes7, challenges remain regarding adoption and use of portals. While some patients are keen to use portals to communicate with their healthcare team and access their EHRs, others are more reluctant5. Characteristics such as patient socio-demographics and medical condition can be predictors of portal use3. The COVID-19 pandemic has impacted patient adoption of video visits and EHR messaging8,9,10.
In this research, part of the broader Role of Electronic Communication to Enhance Patient Trust (RECEPT) study, we explore trust formation and enhancement among patient portal users, during the first year of the COVID-19 pandemic. Our research questions were to (1) determine how portal use impacts trust among patients, either positively or negatively; (2) assess how various portal features influence trust; and (3) explore how trust is experienced differently in three demographic groups.
METHODS
Conducted February through December 2020, this study involved qualitative interviews with patients or their caregivers, from an internal medicine clinic in Colorado. Our research was guided by grounded theory methodology11, 12, a systematic approach capable of providing an in-depth understanding of the complexities associated with patient trust. The study was deemed exempt from human subject protection oversight by the Colorado Multiple Institutional Review Board in August 2019.
Sampling and Recruitment
Prospective interviewees were recruited via three complementary methods. First, patients were identified through an EHR search based on defined inclusion and exclusion criteria. A physician informaticist provided a technique to sort patients who met these criteria and provided this list to our senior research assistant, who then purposively contacted patients stratified by age group, gender, and physician to provide a broad sample (~1000 patients). A standardized recruitment script was used. Inclusion criteria were (1) patient or caregiver of patient at the internal medicine clinic, (2) portal user defined as participating in portal communication once within the past 12 months, and (3) 18 years or older. Exclusion criteria were (1) employees of the clinic who were also patients and (2) patients of the principal investigator. Second, as caregivers were unable to be identified through an EHR search, physician input was elicited to ascertain these individuals. All identified caregivers were then contacted by phone and/or email using our recruitment script. Caregiver was defined as a family member or entrusted person who accessed the EHR portal as proxy for a clinic patient. Finally, we utilized theoretical sampling to recruit certain participants based on emergent findings13. For example, in April 2020, as telehealth experiences became a salient discussion point, we added experiencing a telehealth visit as an inclusion criterion. Thus, interviewees recruited prior to April 2020 might not have had a video visit, while those recruited subsequently were required to have one. This change in recruitment corresponds with organizational shifts during the pandemic, as physicians were transitioned to offer telehealth visits in late March 2020. An incentive of $50 was offered as a gift card. Verbal consent was obtained prior to interviews.
Data Collection
Interviews were semi-structured, conducted via telephone in English, and approximately 30 min in length. Discussion topics included demographic data; information on past portal use; portal experiences; and patient trust including fidelity, honesty, and protection of privacy. The interview guide was developed by the research team and informed by physician-patient trust scales. We explored five well-known validated scales to understand the known components of patient trust14,15,16,17,18. The scale developed by Hall and colleagues14, commonly referred to as the Wake Forest Physician Trust Scale, is the primary scale that informed the development and assessment of our interview guide (see appendix). Interviews were audio recorded in Zoom and professionally transcribed. Interviewing ceased when we found the properties of our themes were well established and that additional interviews offered no new information pertaining to these themes or to our research questions. This “saturation point” was met after contacting approximately half the patients who met the pre-specified inclusion and exclusion criteria.
Data Analysis
Interview data were analyzed in ATLAS.ti version 9.0.20 (Scientific Software Development, GmbH, Berlin) using the constant comparative method11. Codes were developed inductively and applied by two team members. The first seven interviews were coded independently by each of the two team members, who met to resolve coding discrepancies through discussion and consensus. The result was a list of approximately 40 initial codes, many with various subcodes, pertaining to patient portal use and trust (see appendix). For remaining interviews, one team member coded all transcripts, while another researcher simultaneously coded one-third of those transcripts to ensure consistency of coding. Concordant processes of coding and memos on codes enabled the elaboration of codes and clustering of codes into categories. Data were then reviewed a second time by a researcher who applied a set of seven focused codes. These conceptually oriented codes had been identified and agreed upon by the research team through the analysis of concepts and patterns within and across the initial coded data. The themes presented in this manuscript correspond directly to the focused codes.
RESULTS
Overall, 404 patients were approached, and 51 chose to participate. Participants had a mean age of 53 years, were predominantly White (84.3%), and possessed high levels of education (82.4% with a bachelor’s degree or higher). Sixty-one percent of those who answered the question had an annual income of $75,000 or higher, with 20 patients (39%) declining to answer (see Table 1). Sixty-five percent of interviewees felt the “portal” prevented them from a face-to-face office visit, and 42% felt it prevented an urgent care or emergency room visit during the pandemic. We initially analyzed data by cohort (age, gender, caregiver) to determine how trust may be experienced differently across demographic groups; however, we were not able to detect meaningful qualitative differences. Thus, we present findings pertaining to the overall sample.
Our principal findings center on a range of factors elucidating how patients experience trust in healthcare when it is delivered via an electronic portal. This includes both telehealth visits and less formal patient-provider communication such as email messaging and test results conveyed via the portal. Emergent themes can be classified into two general categories: interpersonal factors and systems factors (see Fig. 1). Interpersonal factors are those which concern patient-provider dynamics and directly promote trust. They may be preexisting and therefore relate to an ongoing relationship, or they may be interactive and pertain to patient-provider exchanges during a given encounter. In contrast to interpersonal factors, systems factors are those which relate to the portal itself. Each of these categories and the themes within them are described below. Illustrative quotes are provided in Table 2.
Interpersonal Factors
Interviews elicited information on five interpersonal factors that promote trust: an established, positive patient-provider relationship; a sense that the provider will not use the portal beyond its capabilities or to share serious news; provider promptness of response to communication; provider attention to detail, thoroughness, and organization; and provider knowledge of and support for the portal, as described below.
Established, Positive Patient-Provider Relationship
Several interviewees expressed the importance of having an established, positive relationship with their provider and felt that face-to-face relationships “transferred” easily to the portal. Indeed, many interviewees reported ongoing interactions with their provider that had spanned several years (mean 6.1 years). Having that prior relationship appears to have eased many possible complexities of portal communication and contributed to patient trust. While our qualitative data do not indicate the extent to which a prior relationship is essential to promoting trust via electronic communication, a pre-existingface-to-face relationship appears helpful.
Sense That Provider Will Not Use the Portal Beyond Its Capabilities or to Share Serious News
Many interviewees expressed a high level of trust in care delivered through the portal but preferred that care or communication not be delivered electronically when a better pathway existed. In other words, patients were generally supportive of using electronic communication for certain health concerns but only “as far as that goes.” This was especially true for telehealth, which some interviewees perceived as quite limited in its clinical capabilities. Importantly, interviewees often trusted—and valued—that their provider would know which specific types of care or communication should be provided in person rather than via electronic communication.
In addition, interviewees shared their experiences with and preferences for receiving difficult diagnoses such as cancer via the portal. They overwhelmingly desired to receive serious news in person or over the phone rather than via the portal and trusted that their provider would not use the portal for such purposes. A handful of interviewees were content with the idea of receiving serious news via the portal—if it facilitated the expeditious delivery of results—but nonetheless expressed an interest in conversing with their provider shortly after receiving the results.
Provider Promptness of Response to Communication
More than half of interviewees valued being able to reach their provider quickly and directly and especially appreciated prompt responses to communication from their provider. Promptness not only satisfied patients in general but also led to a heightened sense “that they care.” Indeed, providers’ prompt replies were among the most salient factors contributing to a trusting relationship. Caregivers were most appreciative of the readily available “life-line” the EHR messaging and video visits provided them for loved ones during the COVID-19 pandemic.
Our data also indicate how quickly participants expect their provider to respond to communication via the portal. While a majority of patients anticipated a response within 1 day, their expectations ranged greatly from 30 min to 7 days (see Fig. 2).
Provider Attention to Detail, Thoroughness, and Organization
Several interviewees mentioned the importance of having a provider who is methodical in communicating and providing care via the portal. This emerged as fundamental to a trusting relationship and was described by interviewees as keen attention to detail, thoroughness, and organization. These three qualities helped patients to feel cared for, listened to, and as though they were “in good hands.” All patient messages are received directly by the physician in this clinic.
Provider Knowledge of and Support for the Portal
Most interviewees felt that their provider was familiar with and supportive of the portal technology, and many began using the portal at their provider’s suggestion. Meanwhile, a handful of interviewees noted that their comfort with and trust in the technology stemmed—at least in part—from their provider’s embrace of the portal. Patient confidence was connected to a perception that their provider “trusts the system.” Conversely, one patient noted reservations about the portal because of their provider’s lack of familiarity with it.
Systems Factors
Interviewees cited several systems factors that helped to enable or reinforce trust: easy-to-use portal; perceived secure portal; written records; easy-to-access assistance; and perceived safeguards to prevent errors, as described below.
Easy-to-Use Portal
Overall, interviewees tended to find the portal intuitive and user friendly. However, a good handful of interviewees expressed minor difficulties such as login issues, site navigation challenges, or problems with the app freezing. Usability complications appeared to factor into decisions about how or to what extent they used the portal.
Perceived Secure Portal
An overwhelming majority of interviewees felt comfortable sharing personal health information via the portal and reported sharing the same information (more or less) that they would share either in person or via telephone. Interviewees valued, for example, the secure feel of the website (i.e., the login procedures) and compliance with Health Insurance Portability and Accountability Act (HIPAA) laws. A few patients preferred to discuss sensitive topics in person or via telephone rather than through the portal, but this preference appeared to be related to interpersonal dynamics rather than concerns about security.
Written Records
Several interviewees expressed the importance of being able to access a written record of their provider’s verbal assessment or guidance. In other words, the portal facilitated written communication with one’s provider—either in lieu of or in addition to verbal communication—and this was a valued feature. Written records helped not only patients to remember their provider’s guidance and the details of test results but also their own communication to their provider.
Easy-to-Access Assistance
High patient confidence in being able to access portal assistance was common among interviewees, and this appeared to coincide with overall comfort communicating via the portal. Despite valuing this feature, many interviewees had never accessed help.
Perceived Safeguards to Prevent Errors
Interviewees possessed a high degree of confidence in their provider’s ability to avert errors such as patient mix-ups via the portal. This assurance appeared to reinforce broader themes of trust in the care or communication received electronically.
DISCUSSION
This study contributes to early research exploring trust formation and enhancement among patient portal users. Our findings complement extant research on patient portals, demonstrating these technologies can influence patient engagement and care4, and further define a range of interpersonal and system factors likely to facilitate or hinder optimal portal use19. Our results illustrate factors that promote, enable, or reinforce patient trust of electronic communication, and that pre-existing (prior to electronic encounters), interactive (during electronic encounters), and contextual (system) factors are key to a trusting patient-provider relationship. Implications are extensive.
Our results suggest potential challenges in patient trust relative to the impact of the Final Rule of the 21st Century CURES Act20, which relates to the use of health information via electronic channels such as patient portals. Among the rule’s many provisions is a requirement that results be released to patients immediately as available, often without prior physician review. Many patients in our study noted reluctance to obtain “bad news” via the portal without explanation or advice from a provider, a finding also noted by prior research21.
Important policy and ethical challenges pertain to the widespread adoption of EHRs to not further widen healthcare disparities for patients less technologically literate or unable or reluctant to communicate via electronic devices22. While clinic demographics did not support this study to assess disparities explicitly, our data defines a range of individual and organizational factors that can inform future research on how and to what extent patients’ trust and decisions to utilize care electronically vary among broader demographic groups.
Our findings indicate a potential “uncertainty” gap, wherein patients determine the “right” way to contact their healthcare team, due to increasing choices of electronic messaging, video, telephone, or clinic visits. This was an issue for patients regarding the portal in general and telehealth specifically. A handful of patients expressed uncertainty about the extent telehealth could or should fit into their overall care.
Finally, healthcare workforce and workflow redesign efforts are beginning to evaluate staffing and space to support a “post technology” ambulatory care model with changing—and often significant—workload demands and time constraints23. There is an urgent need to address the burnout many physicians, especially those in primary care, are feeling with the additional time requirements of EHR in-basket tasks and patient messages24. Patients expect prompt and often in-depth responses to electronic communication from providers, underscoring this need to address physician workload.
This study has several strengths and limitations. First, a major strength and possible limitation is that we conducted the study amid the COVID-19 pandemic, potentially impacting responses. This unique research timing allows us to be one of the first to report on patient experiences of electronic communication at a time when face-to-face care was deemed dangerous by many patients. However, it is unclear whether our findings are transferrable to a non-pandemic environment, wherein public acceptance of (or demand for) electronic communication may be different. Second, our caregiver sampling was subject to greater potential bias than other recruitment methods since we relied on physician input for caregiver identification. Conceivably, physicians may have selectively referred only certain caregivers. Third, despite a reasonably large sample size for a qualitative study, we were not able to determine differences across participant cohort (age, gender, caregiver), therefore limiting any comparative conclusions. Finally, our participants were relatively homogenous in terms of socioeconomic status as well as race and ethnicity, and this limits the transferability of our results to diverse patient populations. Research on socioeconomic factors is limited but suggests that individuals with a college education (vs. no college degree) are more likely to access their medical record through an EHR patient portal. This underscores the need to ascertain and understand more fully how socioeconomic factors may impact portal use and trust25. In addition, research increasingly documents differences in trust (and mistrust) of the US healthcare system by various racial and ethnic groups26, 27. It is plausible that a general lack of trust, perhaps in conjunction with other access barriers, may translate to disparities in EHR portal use. Current evidence is mixed and inconclusive25, 28, 29, and therefore it is crucial that future research assesses how electronic portals are perceived and experienced by patients from diverse racial and ethnic groups.
Overall, our study provides key insights into themes of patient trust and indicates that the portal is a highly valued communication tool that can enhance trust and engagement when used optimally for some patients. Important policy work, expanded demographic research, and patient and healthcare professional education remain to be done to support optimal use to understand and maximize this technology’s potential.
