As the Health Information Technology for Economic and Clinical Health (HITECH) Act enters stage 2 of implementation,1 providers must be cognizant of patient attitudes toward health information exchange (HIE) while optimizing their electronic health record (EHR) systems. The crux of health information technology (HIT) integration lies in the ability to improve and enhance the providers’ delivery of care, as well as positive patient outcomes, through meaningful use. According to the Centers for Medicare & Medicaid Services (CMS), benefits of meaningful use must include: complete and accurate information, better access to information, and patient empowerment.1 Health information technology literature has repeatedly shown quality and efficiency benefits with successful implementation of EHR systems into capable healthcare systems. These benefits include increased adherence to guidelines, enhanced disease surveillance, and decreased medication errors.2 EHR systems have demonstrated tremendous promise in improving healthcare delivery efficiency and quality, cost-effectiveness, and patient safety at benchmark institutions such as Regenstrief Institute (Indianapolis, IN), Partners/Brigham and Women’s Hospital (Boston, MA), Intermountain Health (Salt Lake City, UT), Vanderbilt University (Nashville, TN), and Kaiser Permanente Health Care System.3

Lacking, however, is adequate health services research regarding the attitudes and preferences of older patients as compared with  younger patients with respect to electronic communication with their providers. Such research is important, especially with our aging population and the cost of providing care for this population. As of 2011, more than 1 in every 8 Americans (13.3% of the population) is 65 years or older and, by 2040, there will be about 79.7 million older adults (21% of the population).4 The increase in prevalence of chronic comorbidities among the older adult population affords the opportunity for electronic health information exchange platforms to improve health outcomes through patient engagement. Given current patient trends toward consolidation into large healthcare organizations, comprehensive EHR systems can scale effective management of large populations. A  comprehensive EHR system is composed of 2 essential components: (1) the provider network, allowing for storage/retrieval of patient medical records as well as communication between providers, and (2) the patient web portal (PWP), allowing patients (andproxy users) to access certain health records as well as communicate with the medical care team through various functions.
Both components work in unison to enhance healthcare delivery with secure and reliable medical record management, efficient interdepartmental communication, and interactive patient-centered care.

We surveyed older and younger adults who enrolled in a simple, secure patient-physician messaging system, to better understand attitudes and preferences regarding electronic communication with providers. Between April 2010 and January 2012, 46 primary care physicians at UCLA’s Geriatrics and Internal Medicine ambulatory practices, along with their medical care teams, enrolled 3543 patients and exchanged 13,259 messages between them. This study surveyed patients and/or their proxies enrolled in this program to identify end user attitudes, concerns, and preferences and inform the development of a more comprehensive PWP.

METHODS

Patient-Physician Messaging System


Vision Tree is a secure, freestanding, Internet-based 2-way messaging system that allows patients and caregivers to communicate with the medical care team. Patients (or proxy users) do not have direct access to their personal medical records, but can be sent personal medical information through electronic messages. In the pilot program, interested patients were e-mailed a message containing log-in information and  instructions on account setup. Once the account has been set up, the account user is directed to the messaging site landing  page, where one can compose and send new messages and receive and review messages from the medical care team.

Messages are addressed to the provider and triaged by assigned medical staff during regular clinic hours. During triage, medical staff answer messages that are within their scope of work (eg, appointment scheduling, referrals, and authorizations) or forward, via encrypted e-mail, questions that require the physician’s attention. The physician may then call the patient or reply to the medical staff’s e-mail with a response. The medical staff transfers the physician’s response to the Vision Tree messaging system and sends the message to the patient. Once the office’s response is sent, an alert notification arrives at the patient’s e-mail address instructing him or her to log in to Vision Tree to view the new message.

Recruitment

On January 30, 2012, surveys were emailed to patients (or proxies) who, as part of Vision Tree enrollment, had provided an e-mail to the medical office. We surveyed both patients and proxies who had logged in to the messaging system after enrollment (users) and those who had never logged in to the messaging system (nonusers). The e-mails contained a brief study description and a hyperlink to a third party website  hosting the survey. The survey asked questions including age, frequency of healthcare visits (ie, every week, every month, every 2 months, every 3 months, every 6 months, once a year, or other), preferred methods of communication with the medical office (ie, phone, e-mail, postal mail, and/or other), and who had introduced the respondent to the messaging system (ie, medical staff and/or physician). Users were also asked questions about how long they had been using Vision Tree (ie, a few days, a few weeks, a few months, about 1 year, more than a year, or other), system ease of use (ie, not at all easy to use, slightly easy to use, moderately easy to use, very easy to use, or extremely easy to use), the nature of the messages they sent to their physicians (ie, a health question, medication request, appointment requests, lab results, and/or other), barriers to use (ie, forgetting login/password, limited access to computer/Internet, comfort, confidentiality, complicated interface, lack of value, and/or other), and overall satisfaction with the messaging system (ie, extremely dissatisfied, moderately dissatisfied, slightly dissatisfied, neither satisfied nor dissatisfied, slightly satisfied, moderately satisfied, or extremely satisfied). We asked an open-ended question on suggestions for improvement to the messaging system and categorized those responses into 4 groups (ie, simplify interface, increase functionality, expand to more physicians, and increase responsiveness). The survey did not require respondents to complete every question. The survey remained open until February 29, 2012, and e-mail reminders were sent to those surveyed 2 and 3 weeks after the initial e-mail invitation.

Data Analysis

We used descriptive statistics for the entire sample (including both patients and proxies) and compared responses between persons 65 years and older (older adult) and those younger than 65 years (younger adult), as well as between users and non users. We used χ2 tests to compare categorical data and t tests to compare continuous data.

RESULTS

Of the 3543 enrollees e-mailed, 3212 e-mails were successfully delivered (91% of those e-mailed) and 372 responses were collected (12% of those delivered). Of the 372 respondents, 324 (87.1%) provided an age (mean 60.2 years, standard deviation [SD] 16.8). Among the respondents that provided an age, 248 (76.5%) had used the system (users) (mean 60.5 years, SD 16.2) and 76 (23.5%) had never used the system (nonusers) (mean 59.1 years, SD 18.7). Among those users, 192 (77.4%) were patients; 56 (22.6%) were proxies. Among nonusers, 64 (84.2%) were patients; 12 (15.8%) were proxies.

Of the 324 respondents who provided an age, 179 (55.2%) were younger than 65 years (younger adult) and 145 (44.8%) were 65 years or older (older adult). The mean age of younger adults was 48.3 years (range 18-64, SD 12.2) and 74.9 years (range 65-97, SD 7.15) for older adults. Among users, the mean age for the younger adult (54.4%) and older adult (45.6%) groups was 48.8 years (SD 12.1) and 74.5 years (SD 6.7), respectively. Among nonusers, the mean age for the younger adult (57.9%) and older adult groups (42.1%) was 46.3 years (SD 12.6) and 76.6 years (SD 8.5), respectively. Results between user and nonuser groups (Table 1) showed that users make more frequent visits to the doctor’s office. Compared with nonusers, more users were introduced to the messaging system by staff and/or physician.

Among the user population, results between younger and older adults demonstrated a preference for phone, followed by e-mail, when asked what means of current communication with the medical team (Table 2). Results between younger and older adults showed a preference for e-mail, followed by phone, when asked what means of communication they preferred. While younger and older adults both preferred email communication, a higher proportion of younger adults preferred e-mail communication with the medical team compared with older adults.

Results on attitudes and preferences about the messaging system were collected from 248 respondents who had used the messaging system (eg, users) (Table 3). Ninety-one percent reported having used the system for at least a few months. Response rates to each question varied from 59% to 97%. Both younger and older adult respondents found the messaging system easy to use and were satisfied with it. Both younger and older adult respondents reported that most messages sent through the messaging system were health questions, followed by medication requests, lab results, and scheduling issues. When asked, few barriers were reported by users, with forgetting log-in or password being the most common.

Qualitative data collected on system improvements from 163 users included requests for simplifying system interface (19%), increasing features/functionality to the system (19%), expanding messaging to more physicians (11%), and increasing responsiveness to messages (4%).

DISCUSSION

Our data provided us with a better understanding of the attitudes and preferences regarding electronic health information exchange among our younger and older adult patient populations who had enrolled in an electronic patient-physician messaging system. Physician, as well as staff, engagement with patients in introducing the messaging system was an important differentiator between respondents who have logged into the messaging system and respondents who have never logged into the messaging system.

Within a population of patients and proxy users with e-mail who had enrolled in a patient-physician messaging account, there were no differences between younger and older adults regarding attitudes and preferences for electronic health information exchange. Another important finding was that both younger and older adult groups surveyed preferred email as a modality of communicating with physicians and medical care teams. This finding, along with the increased preference for greater functionality of this platform, highlights patients’ and proxies’ willingness and desire to transintion to exchanging some medical care and communication electronically.

Overall, attitudes of the older adult patients about electronic communication were generally positive. Factors associated with positive attitudes included: physician/staff encouragement, improved patient education, a user-friendly program, and increased features and functionality. These suggestions can provide a guide for developers and implementers of future patient web portal systems. Results from respondents who never used the messaging system highlight the need for effective educational material and physician engagement.

Limitations and Future Research

Results of this study should be interpreted with care. The sample surveyed was limited to those who had e-mail and signed up for the messaging service, and surveys were returned by 12% of the patients to whom the e-mails successfully delivered. Therefore our findings may not represent attitudes and  preferences of general patient populations. Future research with larger samples and with more outreach to those who are less computer savvy, as well as qualitative research with small groups of various patient populations, would provide greater insight regarding how to develop and employ patient and provider messaging systems.

CONCLUSION

This study suggests that the younger and older adult patients with some experience with electronic communication will embrace electronic communication for healthcare information. Although a majority of older adult patients have positive attitudes toward health information exchange, electronic communication platforms must address key issues in consumer education/training, physician commitment to use electronic messaging with their patients, and adoption of an accessible interface to ensure productive older adult consumer participation. Successful patient and physician engagement may have implications in patient empowerment and positive health outcomes.
