Discussion
Results revealed that when discussing their views on PHRs, young adults identified benefits previously voiced by older patients and other stakeholders. Participants emphasized accessibility of personal information as a priority - unsurprising given that within this age group, relocation is common and they are accustomed to easy and immediate access to information through smartphones. They also stressed the value of an integrated system–to them, the act of putting information online necessarily implied and required greater connectivity to people and information systems. They believed that it was their generation that would be more likely to adopt this type of technology, and suggested that healthier and more educated individuals might be more likely to use it, echoing the findings from Weingart et al.40 Though their generation is apt to share many personal details of their lives on the Internet, the self-described ‘Facebook generation’, participants expressed concerns about privacy and security similar to what has been previously reported in other, older populations.23,41–47 However, they demonstrated an awareness and concern about how their information could be sold and exploited for commercial use. Despite their concerns about how information could be collected, compromised, they suggested that it could be mitigated by convenience (using the example of online banking), though it was not conclusive.
What was striking was how the focus and motivations changed when participants considered how they would personally interact with the PHR. Their prior experiences with technology, the health care system and their perception of their health played a big role in determining their individual expectations about using a PHR. Participants stressed the importance of usability, or ease-of-use, which has long been considered a crucial element for adoption of information technology. 48–50 Moreover, since PHRs are user-driven, having a system that is easy to use becomes even more essential for uptake. However, what contributes to ease-of-use may vary between populations. While in a report on PHR usability, Marchioni49 believes that customization is important for older users and people with specific chronic health conditions, our findings suggest that customization is equally if not more important for younger and healthier users. Since they are not using it to actively manage a condition but looking to use it for preventative health, they want the PHR to require a minimum of effort and be tailored to their needs. Their expectations of a new or prospective technology like the PHR were grounded in their experiences with existing technologies, especially ones that they used on a day-to-day basis. For example, the need to have control over exactly what elements they shared and who they shared it with was compared repeatedly to Facebook’s privacy settings. Google was used as an example of clean interface design, but also as an example of how information can be mined or used for more directed advertising. Young adults expected to be able to do, at a minimum, the same things if not more with a PHR as they do with existing tools.
As young healthy adults, participants primarily considered the PHR in the context of preventative health. They expected to use the PHR to play a role in maintaining good health, and exhibited an awareness and recognition of the role of lifestyle choices, such as diet and physical activity, in preventing illness. They saw the PHR as a way to help keep track and become aware of these choices and how they impacted their health. They expected that the PHR could help them learn or understand what they should be doing, by providing reputable and up-to-date health information resources, guidelines, targets and facilitating the ability to compare themselves to their peers or the average. Participants also expected and stressed the ability of the PHR to help them become aware of what they were actually doing, to become more conscious of choices that they might be making in their everyday life that needed to be changed. Lastly, they spoke considerably of the PHR providing reinforcement or reward in such a way that it would not only encourage them to continue tracking, but also encourage them to keep making positive lifestyle choices. This sense of ongoing achievement and motivation was considered crucial in having the PHR be used to encourage preventative health behaviours. In the particular subpopulation of young adults, our study corroborates what the scarce evidence on this topic seems to point out, namely that PHRs may support and promote preventative care.51,52
The literature has promoted the idea that one of the major benefits of PHRs is its potential to increase the involvement of patients in their own care.4,7–10 Our results support the idea that young adult users similarly expect the PHR to increase self-management in their own care. However, young adults not only envisioned the PHR as a way to have more ownership in their health but also as a means to become increasingly independent of the health care system. The majority of participants expressed considerable frustration with the health care system and issues with access to care or quality of care. Though they simultaneously recognized that it was due to the limited resources of the health care system, participants were discouraged by long waits and difficulties seeing a doctor. In fact, only one-third had a regular physician in Montreal, and one-third did not have a regular doctor whatsoever. Issues with access to care motivated them to look to the PHR to address these issues by either improving the efficiency of existing services or largely as a way to avoid care altogether. Many young adults already used Internet to seek out health information, or to ‘Google’ symptoms, and as a way to self-diagnose as opposed to seeking out the opinion of a medical professional. In fact, some considered it a preferable first step, before investing hours in a waiting room. Even though they recognized potential dangers and pitfalls of Internet self-diagnosis, they preferred it as an alternative to scheduling a medical visit, and therefore wanted the PHR to serve as a source of more authoritative health information.
Another concern was the challenge and suggestions as to how to make the PHR worthwhile to users. While the perceived burden on time and effort has been discussed as a barrier to HIT adoption in the professional and organizational context,53,54 these results suggest that it is equally important in systems geared towards the patient or consumer as the end-user. Having grown up in the information age, young adults are faced with the increasingly fast-paced demands of modern life. Many participants spoke of already feeling pressured or burdened by existing commitments, and had no interest in adding another obligation. They only saw it as being useful if it in turn provided some discernable advantage, either through convenient timesaving features or through instantaneous feedback. The importance of interactivity and reward has not yet been explored in existing PHR literature, though has since been seen increasingly in consumer health and wellness technologies, such as fitness trackers and weight loss apps. Young adults are used to interacting with technology and using it beyond a functional pragmatic level. Technology is part of their leisure and games were repeatedly stressed as a benchmark for how PHRs for prevention could be made more appealing. It suggested that a sufficiently motivating system might be able to provide the impetus to encourage better health decisions.Though the need for interactivity and reinforcement is particularly important when PHRs are used for prevention in healthy individuals, this finding suggests exploring ways to make the PHR more satisfying or ‘rewarding’ in order to encourage lasting, long-term adoption.
Based on these results, we are proposing a conceptual framework that may help explain the influence of three major driving forces on the expectations of use of PHR in young adults (see Figure 1): experience with existing technology, experience with the health care system, and perception of health and health risks. Participants referenced systems they already knew as indications as to what they could and did expect from PHRs. Secondly, the individual’s experience with the health care system shaped their expectations about using a PHR as well. Frustrations and difficulties with access and getting care led them to see the PHR largely as an alternative to care. Lastly, the individual’s perception of their health and health risks influenced their personal needs for managing their own health. In the case of young adults, this led to the primary expectation that PHRs would be used for preventative health, rather than disease management.
This framework, derived from our inductive analysis of the empirical data on young adults and PHRs specifically, is coherent with other broader models of technology acceptance, such as the TAM. The expectations of using a PHR encompass both perceived usefulness and perceived ease-of-use. Perceived usefulness of a PHR is influenced by young adults’ experience with the health care system and the perception of their health, while their experience with existing technology helps constitute what they consider to be ease-of-use. Moreover, in a preventative context, ease-of-use is even more crucial to ensure uptake. In fact, Venkatesh and Bala55 suggested a theoretical framework synthesizing prior research on TAM, with four different types of determinants on perceived usefulness and perceived ease of use: 1) individual differences, including personality and/or demographics; 2) system characteristics, or ‘features of a system that can help individuals develop favourable (or unfavourable) perceptions regarding the usefulness or ease-of-use of a system’; 3) social influence, or social processes that guide individuals to formulate perceptions of an IT; and 4) facilitating conditions, or organizational support that facilitates the use of an IT.55 In this view, our framework focuses on individual differences, namely the users’ experience with technology, experience with the health care system and motivations with regard to taking control of their health. These individual characteristics warrant further exploration and research when targeting PHRs towards specific populations. Given the spectrum of differences in individuals and health care contexts, this supports the idea that PHRs will absolutely need to be customizable, in order to meet what could be a broad range of subtle, yet important differences between potential users – an idea that was stressed by participants themselves. However, this framework only considers user expectations, so an exploration of what will deter users from adopting PHRs warrants further study.
This study suggests that there is potential for PHRs to be a tool in preventative health, but that to do this, we should look at PHRs more generally as ‘user-centered’, rather than ‘patient-centered’. More research is needed to understand what can influence user expectations or perceived usefulness, and how to arguably not only make PHRs easy to use, but inherently satisfying, in order to ensure lasting uptake. As our framework also suggests that experience with existing technology is important in determining perceived ease-of-use, future research could analyze characteristics of technologies widely adopted in specific user populations, such as young adults, to provide a better grounding in designing what should be incorporated into PHRs. In using PHRs not only for managing disease, but also for managing wellness and health, there is a better possibility for this technology to become broadly adopted.
