Abstract
Objective Patient use of online electronic medical records (EMR) holds the potential to improve health outcomes. The purpose of this study is to discover how patients living with chronic inflammatory bowel disease (IBD) value Internet-based patient access to electronic patient records.
Design This was a qualitative, exploratory, descriptive study using in-depth interviews and focus groups of a total of 12 patients with IBD of at least one-year duration at University Health Network, a tertiary care center in Toronto, Ontario.
Results Four themes have been elucidated that comprise a theoretical framework of patient-perceived information and communication technology usefulness: promotion of a sense of illness ownership, of patient-driven communication, of personalized support, and of mutual trust.
Conclusions For patients with chronic IBD, simply providing access to electronic medical records has little usefulness on its own. Useful technology for patients with IBD is multifaceted, self-care promoting, and integrated into the patient's already existing health and psychosocial support infrastructure. The four identified themes can serve as focal points for the evaluation of information technology designed for patient use, thus providing a patient-centered framework for developers seeking to adapt existing EMR systems to patient access and use for the purposes of improving health care quality and health outcomes. Further studies in other populations are needed to enhance generalizability of the emergent theory.
Electronic forms of information and communication can promote the emergence of patients as strategic partners in health care.1 Active use by patients of electronic mail, personal health records, and the Internet, especially integrated within the context of an effective physician-patient relationship, holds the potential to improve both individual and organizational health outcomes.2 Integrated, comprehensive, two-way information and communication technology (ICT) are envisaged as part of the future of patient-physician interaction.3
There are numerous barriers facing the implementation and integration of patient-use ICT. In the case of patient-accessible electronic medical records (EMR), at the level of health care organizations, insurers, and health systems, many of these barriers are political, fiscal, and cultural.4 At the physician level, concerns about patient misunderstanding of physician notations as well as concerns over a loss of control over patient interactions and increasing workload complicate the acceptance of these technologies.5 6 At the patient level, barriers include the individual's state of general health, uncertainty, perceived social support, age, education, income, race, general literacy, functional health literacy, learning styles, psychological profile (e.g., health locus of control), perceived self-efficacy, access to computers and the Internet, perceived cost, and perceived difficulties of health provider access,6 as well as fear (of death, incapacity, or cancer), guilt, and concepts of disease as retribution or punishment.7
Yet patients are broadly and successfully implementing information technology in self-care and self-management despite these concerns, as evidenced most notably by exponential growth in the use of the Internet by the general populace for health information seeking. This apparent paradox exists because patients assess both the value of the Internet and their capacity to use the Internet from their own frames of reference and are motivated to use the Internet to meet their perceived needs. In other words, patient acceptance and use of the Internet for health information seeking is realizable because patients perceive that there is a seemingly good fit between the Internet and their perceived needs, wants, and capabilities.8
Conversely, a lack of a definitive characterization of the patient's point of view may be responsible in part for the uneven record of patient-directed ICT such as access to EMR9 and online peer-to-peer communities10 to demonstrate consistent, measurable impacts on health outcomes. Therefore, the onus is on the health informatics research community to develop sound theoretical models for the design and evaluation of patient-use ICT that take into consideration the unique challenges of being a patient.
Background and Rationale
More than 40% of patients have at least one chronic illness, accounting for nearly two thirds of all medical expenditures.11 Because of their long time frame and high attendant costs over time, chronic illnesses lend themselves to electronically mediated self-management tools.12 Prototypes of Web-based, patient-centered ICT have been demonstrated to support self-management of illness and enhance understanding of the complications of poorly controlled disease.13 14 Patients living with chronic illness are also more likely to use health information than their healthier counterparts,15 although each chronic illness has specific, recognizable challenges for affected patients in symptom comprehension, information management, task fulfillment, and social interaction.16
A descriptive, exploratory research approach such as grounded theory is well suited to uncover the nature of chronically ill patients' perceptions of reality, how these perceptions create meaning with regards to the specific phenomenon of access to medical records, and how the patients' subjective meaning about this phenomenon contributes to their eventual acceptance and use of EMR.17 Iterative interplay between data collection and analysis allows for the “emergence” of concepts directly from the language and perspectives of the actual chronically ill patients.17 Subsequent integration of these concepts with the researchers' interpretation of the literature results in a theoretical framework that is “grounded” in the realities of chronically ill patients. This “grounded theory” should then form the basis for the development of systems and evaluation tools that capture this subjective reality of potential patient-users. In contrast, development that is guided solely by information system designers' and clinicians' beliefs about patient-users may result in ICT that do not fit with the actual challenges and informational needs of patients living with chronic illness in the community.7
Methods
Research Setting
The setting for this research was the “iChart” project at University Health Network (UHN) in Toronto, Ontario, a collaborative research initiative that partnered patients, clinicians, and technical specialists in the design and development of patient access to online EMR. The original intent was to study a group of patients affected by one chronic illness. Although many patient groups were initially considered, a strategic decision was made early on in the study to focus on inflammatory bowel disease (IBD) patients. Despite concerns over limits to the generalizability of eventual results, this proved to be the most fruitful choice because of ease of access for the research team to this particular patient population.
Inflammatory bowel disease is a prototypical chronic illness: complex origin and insidious onset followed by a trajectory of long duration with unpredictable exacerbations and remissions, psychosocial etiologies and ramifications, incurable or nonspontaneously resolving with the potential for long-term functional or physical disability, with numerous strategies for direct and indirect treatment, and in which patients are active agents in management.18 Inflammatory bowel disease patients also tend to be of younger age groups, more technologically aware, and highly interested in self-management of their disease.19 The specific psychosocial (e.g., body image, loss of control, feeling dirty, isolated, fearful, lack of medical community information and support) and physical (e.g., bowel symptoms, energy loss) concerns of IBD strongly affect patients' health perceptions and interpersonal relationships.20 21 22 Psychosocial stresses arising during daily living are an important etiologic factor in IBD exacerbations.23 The potential for discordance between patient and physician perceptions of IBD erodes communication, treatment adherence, and health outcomes.24 25 26
What is already known about the perspective of the patient with IBD on the use of information in illness self-management appears contradictory. Generally, patients subjectively and objectively need more information than they already receive from their physicians and other resources.27 28 29 30 While there is high interest in online information, self-reported use of the Internet for information and support is low.31 Paradoxically, more information may cause either no impact on or worsening of health-related quality of life and psychosocial adjustment.32 33 34
Sampling Procedure
The study used a systematic, nonprobabilistic sampling procedure.35 Informants were chosen if it was thought they were likely to possess experiential knowledge of living with chronic illness and personal medical information: Subjects were required to have lived with a long-term incurable illness for at least one year. There were no restrictions on age and gender, nor was computer, technology, or Internet experience a requirement for entry. Subjects were told that the interview was part of a hospital-based initiative to develop access to patient records over the Internet, but previous experience with medical records was not specified as a criterion for study entry. Subjects were reimbursed solely for personal expenses related to attending the interview.
The initial focus on patients with IBD was considered “convenience based” because one of the researchers (PGR), a practicing gastroenterologist, facilitated access to a subject population. However, remaining with patients with IBD was a purposeful sampling decision because, as described above, IBD fit the characteristics of a prototypical chronic illness.17
Subsequently, our sampling strategy evolved into a theoretically driven sampling process: After the initial focus groups, sampling selection identified patients with IBD with a variety of personal attributes that could either substantiate or negate previously observed findings,35 including experience with information systems, other comorbidities, health care–related work experience, self-professed biases against the Internet and computers in self-care, and technological “illiteracy.” In total, 12 patients with chronic IBD of at least one-year duration were interviewed either in focus groups or individually in depth (Table 1).

Data Collection Procedure
The UHN Research Ethics Board approved the study. A set of open-ended questions about information, medical records, and EMR access and use (Table 2) was employed in in-depth interviews and focus groups limited in duration to 90 minutes. One facilitator assisted by one note taker conducted each session. Each session was recorded and transcribed verbatim. The qualitative research software N-Vivo (Version 4, QSR) was used to manage data and to provide a structure for analysis.36
Interview and Focus Group Questions
In addition, seven “mock pages” from an online medical record were shown to participants during each session (Fig. 1). These were nonfunctioning to avoid bias related to a patient's fascination with the particular technology. After the first focus groups were completed, transcribed, and analyzed, some patient-generated ideas were integrated into the mock Web pages to stimulate more in-depth discussion during subsequent interviews.

Data Analysis
A “responsive” approach to data collection and analysis in which data extracted from earlier transcripts were compared with more recent transcripts and the literature, termed the “constant comparison method,” was employed throughout the study. Data analysis took place both simultaneously with and immediately following data collection (interviews and focus groups). As concepts and apparent gaps emerged, methods for sampling and data collection evolved to address those gaps.37 38
The researchers employed a three-stage analysis of the transcript data.39 In the first stage, termed “open” or “substantive” coding, transcripts were deconstructed into component key words and phrases. These codes were then grouped into a loose framework of ideas, a procedure known as “axial” coding. These ideas were then grouped into a more structured framework of higher level themes, a procedure known as “selective” coding.17 Each subsequent transcript was deconstructed in a similar manner, but the higher level codes evolved to reflect the integration of newer ideas emerging from the transcripts into the overall coding structure.
While actively immersed in the data collection and analysis, researchers frequently reflected on coding decisions. Researcher “reflexivity” was important because it allowed researchers to bracket their biases, knowledge, experience, and personal feelings to minimize their influence on the analysis process.40 For methodological rigor, it was important to create an account of these reflections as they occurred. Memos, or brief documents automatically generated and linked to lines of text in the working transcript by the N-Vivo software, were employed throughout the analysis to document not only this researcher reflexivity, but also researcher thinking, discussion, and decisions as well.41
Two subsequent individual in-depth interviews were scheduled to address possible inconsistencies and gaps in the early codes and to confirm conceptual saturation.35 Conceptual saturation refers to the end point in the qualitative data collection and analysis process, when further data collection and analysis cease to generate any new or distinctive categories, high level concepts, or substantive codes.42 As opposed to quantitative analysis, in which an ideal sample size is calculated before data collection based on previous research and literature review, final sample size in qualitative research is driven by the prospective discovery of concepts, and hence there is no specific number that represents an “ideal” sample size.43 In our study, conceptual saturation appeared relatively early, after ten subjects, and was subsequently confirmed by comparing our preliminary conceptual structure with one generated from the analysis of two transcripts by a second, independent researcher, revealing no new, distinctive higher level concepts or categories.35
One of the key distinguishing features of the grounded theory “approach” is “theoretical coding,” the reinterpretation of the final categories as composite hypotheses of an overall theory, using a thorough literature review as an informant.17 The literature review identified the concept of “usefulness” as an overarching theme that could reasonably link the four highest level categories into a unified framework. Categories were then renamed to bring them in line with language employed in the literature.17
The study's trustworthiness was assessed through an evaluation of three criteria: transferability, credibility, and dependability.42 Transferability, the qualitative counterpart to external validity, was intimately linked to the theoretical sampling procedure. To construct trustworthy theory, it was imperative to access the richest palette of subject characteristics possible to ensure that the sample itself did not limit the final conclusions. Therefore, transferability was established through inclusion of patients with progressively greater variation in individual characteristics, yet whose voiced priorities and perceptions remained decidedly comparable with naïve, earlier subjects. Credibility, the qualitative counterpart to internal validity, was established through triangulation of data collection and analysis methods (interviews, focus groups, and literature review), independent review of findings by the researchers, and member checking (review of key findings and the researcher's interpretations with selected participants). Dependability, the qualitative counterpart to quantitative reliability, was demonstrated through similar findings or conclusions reached by another independent researcher.
Results
Clinician researchers in e-health assert that useful Internet-based solutions for chronic illness self-management facilitate self-monitoring of clinical signs, provide ready access to explanatory information, personalize content, and enhance communication between patients and providers.44 However, because this study's focus is specifically on the patient's voice and the data are somewhat removed from physician-predefined meanings of information technology usefulness, four related but different themes emerge from the data that encompass patient-perceived usefulness: illness ownership, patient-driven communication, personalized support, and mutual trust between physicians and patients.
Illness Ownership
Useful information technology promotes and supports illness ownership or the capacity of a patient to act on his or her own
behalf when appropriate to directly influence his or her illness trajectory.45 To own illness, patients must have the power to knowingly participate in their care. They must possess an awareness of their
illness, the choice to decide whether they wish to create change, and be afforded the latitude and legitimization to act on
their own intentions.46 If patients perceive ownership of their illness, they are more likely to use tools that facilitate the management and solving
of their problems.47… And if you actually can see your past and see your test results and you know that you've cheated, you can kind of relate why, and take responsibility and make changes … —Interview 2, Line 641
Table 3 illustrates a small part of the interpretative process taken to arrive at the concept of illness ownership. From several discussions and comments in the transcripts on the subject of patient diaries, words and short phrases have been extracted verbatim. The words and phrases are simplified, where possible, as single-word codes. Related codes are grouped into a set of early concepts or axes. For example, “writing,” “recording,” and “thinking” are all actions that patients do that result in the diary's content. The fact that patients actively determine content gives them power, and having power over their illness is one aspect of ownership.
An Example of the Interpretative Process Leading to the Theme of Illness Ownership
Illness ownership is also born of experiential knowledge: living with illness, amassing information, and administering treatments
over time.48 49 For patients with IBD, useful EMR further promotes illness ownership through on-patient-demand access to historical data,
physician's notes, test results, and explanatory information about relevant laboratory and disease markers, including explanations
about things that patients may consider important but clinicians may not.Anything you can learn is helpful. When you have something, you want to know everything about it, the good and the bad. What can happen to you if you don't eat properly or medicines don't take? I want to know the worst and the best … —Interview 3, Paragraph 71
A useful information technology also facilitates healthy practices that allow for the creation of change.50 For patients with IBD, the EMR could (or should) provide a template for arranging appointments and consultations; a workspace from which diet, exercise, and illness-related tasks can be managed; a diary to allow contribution to the medical record; an interface to encourage active participation in research; a resource for appropriately formatted information to accurately and expeditiously fill out disability and insurance forms; and information that piques the patient's interest. Control over the creation of change in their lives is another aspect of illness ownership.
When a patient describes his or her illness experience, it may be quite structurally different from the physician's report.
The physician synthesizes the patient's story into an efficient, objective, problem- or disease-focused medical record, and,
as a result, many of the patient's values and priorities are not documented.51 From the perspectives of patients with IBD, their reality is not captured in the medical record, making it somewhat difficult
to recognize the illness experience described in the document. The record becomes less meaningful to the patients as a reflection
of their lives and, as a result, less useful. In contrast, when patients bear the responsibility to record the facts of their
illness experience from their own perspective, this promotes the patient's sense of illness ownership.… I would have the symptoms and the descriptions and then a chronology … other medical problems … my own treatments … self-help treatments did you do … that would sort of complement the doctors.—Focus Group 3, Subject 2, Paragraphs 101–117
Letting the patient's voice and understanding guide EMR structure and content and letting the patient's voice direct at least
some care decisions that emanate directly from the patient's documentation promote the sense of illness ownership that enhances
the perceived usefulness of patient-accessible EMR. Patients can control who has access to and stewardship of their information.
They can also monitor and verify medical record content, take an active role in managing disease exacerbations and complications,
and perform some autonomous decision making.[It] would be my responsibility to look up my test results and if it would be low maybe I would have to get in contact with the doctor; or at that point, you can even … read up on ways to improve your [problems].—Interview 2, Paragraph 696
Patient-Driven Communication
Electronic communication offers opportunities for meaningful patient participation in illness management, decision making,
and knowledge creation.3Let's say I have an appointment with my doctor, I will look back to … what I have written … then I see my doctor, [and the] doctor says “how are you” … at least I have something to report.—Focus Group 3, Subject 2, Paragraph 211
For patients with IBD, useful EMR integrate such communication tools as e-mail links, online bulletin boards, chat rooms,
and online consultation services that change the norms of patient communication with physicians, other care providers, other
patients, and ancillary health personnel. This communication shift gives patients with IBD greater personal control over the
course of their illness and how interactions with physicians are initiated.A patient … [has] been in ER and is having surgery and says [to the doctor] “you didn't look at the record” or “you didn't take the effort to do it” … when the doctor is not necessarily prompted to review that record … the patient [should have] a little pop up [reminder] that says if your medical condition deteriorates, you must notify your physician right away … [it] puts the responsibility back in the in the hands of the patient … —Interview 1, Line 1,629
Therefore, for patients with IBD, patient-driven communication means real change in the dynamic of physician-patient interaction.
They envisage a new type of partnership between physicians and patients for sharing of information and responsibilities, a
real appreciation for what patients know, and taking some burden for the patient's management off the shoulders of the physician.I would probably [use the online chart] if I knew … that the physician would access that prior to an appointment … If the physician didn't read it, if it was more of a personal thing [just for me to do], I don't know if I would kind of follow through with that.—Focus Group 3, Subject 1, Paragraph 199
Ultimately, patient-driven communication affirms that the patient owns his or her illness and that the physician-patient with
IBD relationship evolves from one of passive dependency and expectation to one of interdependency, mutual appreciation, mutual
support, and shared problem solving.52[The doctor] isn't sitting at the desk opposite you [when you are entering information], grilling you and asking you the really pertinent questions to make sure that your facts are straight … the risk is that the patient incorrectly puts data in and then your doctor may draw the wrong conclusions … —Interview 1, Lines 1,580–1,604
Personalized Support
A patient's adjustment to chronic illness is made positive by the perception of support.53 A chronic incurable illness such as IBD, as with other uncontrollable events, benefits from two types of support: nurturing
(such as emotional, self-esteem, and network forms of support) and action facilitating (such as informational and tangible
forms of support). Ideally, nurturing support is best provided throughout each patient's personal life experience, whereas
action-facilitating support is of greater necessity during intermittent periods of crisis or exacerbations.54… You want to be able to feel comfortable that you know that there is someone else at the other end … —Interview 2, Line 1,052
From the IBD patient perspective, useful EMR provide support that is personalized to the specific needs, wishes, comprehension capabilities, and experiences of each individual patient. Informational requirements, emotional support needs, knowledge, and understanding vary and evolve over the trajectory of an illness. The scope and depth of this support should be adjustable to each individual patient as he or she acquires knowledge and experience. For example, such easily accessible support could help patients cope quickly with the inevitable negativity that arises at times in the long trajectory of IBD (without making them feel they are wrong or “bad” to be experiencing such negativity), or if they come in contact with people who misunderstand or are misinformed about the illness.I don't want people to think that I'm contagious … I want people to know that it affects other parts of your body and it does other things to you … I want people to know what I have to go through and I want them to be able to understand me more … I am not ashamed of what I have and I think that people should be educated on it … —Interview 3, Paragraph 287
For patients with IBD, useful EMR would therefore have to be customizable to the abilities, interests, and technological familiarity
each individual patient.50Because I don't deal in this world every day it would be my main concern that [the patient's chart page] is as clear and easy as possible.—Focus Group 3, Subject 3, Paragraph 528
Mutual Trust between Physicians and Patients
Trust is two-way interdependency built on mutual feelings of freedom and intimacy between one individual and another: in a
trusting relationship, individuals feel secure enough in who they are so they can open themselves up to others and realize
their goals.55 Trust is important in therapeutic relationships between patients, health care organizations, and professionals56 and is requisite for the promotion of patient self-actualization and empowerment behaviors to improve patient health outcomes
and quality of life.57So you [and your doctor] are sort of on the same page, so to speak. That would be pretty helpful.—Focus Group 3, Subject 1, Paragraph 203
The distinction between a patient “looking at” and “using” his or her medical records to improve their health is grounded in the mutual trust between physicians and patients.58 The trust embodied in the relationship with their physicians is automatically transferred to a patient-accessible EMR system
when trusted physicians support such a system.I assume that my doctor will inform me regardless … [not] just because I have access to this that I am going to be on it.—Interview 3, Paragraph 358
Patients with IBD expect that the doctor and the hospital that they trust have already ensured the privacy, security, and
confidentiality of their personal information and the believability and quality of supportive health information. However,
in another study, it was found that a lack of trust in physicians and the health care system is linked to a patient's desire
to look at his or her medical records but not necessarily to use the records positively toward health gains.59I found it very difficult to access … personal information about being misdiagnosed … it was confrontational … —Focus Group 3, Subject 1, Paragraph 73
Paradoxically, even in the presence of “empowering” EMR, relationships with providers still remain the patient's “safety net”: supporting patient illness ownership only if the patient feels that he or she possesses the self-efficacy to do so, while always supporting patients with professional confirmation and empathy.48I don't want to look up and find out that there's been an abnormality on my colonoscopy or my mammogram. I think I'd want to hear from the physician first, then I'd like to go on and read it myself.—Interview 4, Paragraph 315
Although patients with IBD are more likely to assess a new information technology as useful if it is implemented in an environment
that they trust, they still welcome the opportunity to ensure the integrity and meaningfulness of their personal information.60… Sending an email to the information system that would update … and then of course they would have your e-mail as backup … if something goes wrong down the road, they would say well where did you get that information from?—Interview 2, Paragraph 972
Ideally for patients with IBD, trusted relationships affirm their aptitude to exercise self-care intentions through the EMR,
even if some of these intentions may appear counter to the traditional patient role61: self-diagnosis, self-triage, self-referral for consultation with dietitians and other professionals and direct access to
physicians and to a community of support on demand.I'd rather [not] wait a couple of days for my doctor to call me … If it has gone up, that means I have to take one iron pill a day. If it has gone down, I have to take two. A couple of days of feeling better, to me, is worth it … A good day for me is very important.—Interview 3, Paragraph 187
Discussion
Patients in this study evaluate information, technology, and the monitoring of results in terms of their meaningfulness, impact, and usefulness in self-care. The vision of useful EMR of the patient with IBD is a comprehensive informational, emotional, and tangible support ICT that are more complex than an EMR access portal alone. This vision also transcends the original iChart project hypothesis that patient access to their EMR can be an important adjunct to the delivery of quality health care.62 In fact, patients think that it is inadequate just to provide access to test data, laboratory reports, and doctor's notes.
Since patients manage most health problems without any direct participation from health care professionals,63 it makes sense that patients would define a useful information technology as one that supports self-care through the provision of timely access to services, interaction within the social context of health care, assistance in the interpretation of biomarkers, availability of relevant information, and the construction of healthy practices.16
Implications for Research Transfer
To design and evaluate a new generation of useful ICT for patient-users, researchers and system designers require sound theoretical models that adequately capture the determinants of a patient-user's motivation to use such technologies.64 Theories of behavioral motivation can provide valid conceptual frameworks to assess the influence of individual, technical, organizational, and social network characteristics on a potential user's likelihood to use an information technology, even before the technology is fully developed and implemented.65
Satisfactory patient-specific theoretical motivational models to predict ICT use behavior do not yet exist, so they have to be adapted from other fields and academic traditions. For example, in the organizational behavior literature, the Technology Acceptance Model (TAM) provides one possible theoretical framework for understanding information technology user behavioral motivation. The TAM has been employed extensively in the workplace context but has not been studied in patients.50 66 67 In this model, perceived usefulness is considered the strongest motivational predictor of information technology use. Davis50 has defined perceived usefulness of information technology as “the degree to which a person believes that using a particular system would enhance his or her job performance” and that “within an organizational context, people are generally reinforced for good performance by raises, promotions, bonuses and other rewards.” However, since patients with IBD are not employees of the health care organization, reinforcements for use of information technology by patients are much less obvious. Since a patient's motivation, setting of actual use, and informational needs are different from employee-users or professional-users,68 a patient's perception of ICT usefulness may be quite distinct as well.
For patients with IBD, tangible technology (e.g., structure, communication tools, and informational content) and its concomitant functionality (e.g., monitoring, management, and communication) are useful in the long term only if they are actively made meaningful. The patient is the owner of his or her life and illness, and the IBD illness experience is a highly personal and individual experience. Informational content and record structure should be adjustable to the comfort level, wishes, and abilities of each individual patient. Capacity for communication with care providers should be streamlined and integrated into the technology. Access to resources should be driven by patient-assessed need, facilitated during periods of stress or crisis when more immediate action is needed, but available throughout the longer quiescent periods of the illness trajectory, when nurturing forms of support are more appropriate. Integration into the existing relationship of trust between patients and physicians envelops the ICT with characteristics of reassurance, security, and relevance that maximize the patient-perceived usefulness.
Limitations of the Current Study
Unlike a quantitative study, the “results” of a qualitative study are extracted largely from descriptions or texts.69 Results are presented in the form of an emergent theoretical framework grounded in the textual data and related to the literature, and the reader is asked to accept the researcher's interpretation as truth. The interpretative nature of such inquiry limits the study's generalizability, a limitation of most interpretive qualitative studies that makes many quantitative, positivist researchers uncomfortable. However, because the ultimate goal of patient-accessible EMR is to promote the kind of real patient behavioral changes that can positively influence health outcomes, having rich narrative data explicating the patient's perspective on the technology is both crucial and necessary.
Nevertheless, the research agenda must go further to validate the theory through study of other patients with IBD, as well as other groups of patients and even people unaffected by illness. It is hoped that the emergent theoretical framework of patient-perceived usefulness can then be applied in a more structured manner in the form of a validated questionnaire to guide the formative evaluation of personal health records to empower patients toward greater participation in illness management.
Conclusion
Health informatics researchers need to expand research strategies for patient accessible EMR if this technology is ever going to effect desirable patient behavioral changes and improve health outcomes. The patient-user's perspective on what constitutes technology usefulness is both distinct from and complementary to that of physicians and developers. To build useful ICT tools for patients, direct patient participation must be made part of all steps in the design and development process and, most importantly, in the earliest conceptual stages. Therefore, interpretative analytic approaches such as grounded theory should become an integral part of an ICT research agenda.
