We conducted a cross-sectional survey to capture patients’ experiences using the My Kanta patient portal.

My Kanta is a web-based patient portal for all residents with a Finnish personal identity number and access to electronic identification. Patients can view their own or their dependents’ health data (consisting of records of health care visits, diagnoses, critical risk factors, laboratory tests, x-ray examinations, referrals, health and care plans, and medical certificates, statements [20], and e-prescriptions), request a prescription renewal, and save living wills and organ donation testaments [29].

My Kanta is a part of national Kanta services that integrate and save medical, health, and prescription data for health care providers, citizens, and pharmacies [28]. All public and private health care providers that use electronic patient record systems are obliged by law to send prescription and health data to Kanta services [7]. Health data, test results, and prescriptions can be used by health care units with patient consent [28], which can be given or withdrawn on My Kanta.

According to international benchmarking, My Kanta provided patients and their caregivers with the best access to their health record data alongside Korea in 2019 [30] and also provided the most functions in 2016 [31]. However, My Kanta does not allow typical patient portal functions, such as appointment booking or communication with health care professionals.

The web-based questionnaire included 4 open-ended questions and 11 questions with Likert scale or multiple choice response options (Multimedia Appendix 1). The topics of the questions were (1) reasons for logging into the patient portal and whether the visit was successful or not and why; (2) subjective usability of the patient portal; (3) usefulness of the features of the patient portal; (4) the benefits and challenges of reading health care professionals’ notes and discussing their notes with them; (5) improvement ideas for the patient portal; (6) guidance on reading the notes; and (7) background information.

To assess perceived usability, a 2-item questionnaire based on the Usability Metric for User Experience [32]—the UMUX-LITE scale [33]—was used. UMUX-LITE scores were transformed, using a corrective regression formula [33], to System Usability Scale scores. The System Usability Scale is the most frequently used questionnaire for measuring the subjective usability of eHealth apps [34]. Borsci et al [35] tested UMUX-LITE with health care professionals and found it to be appropriate for use in the context of health care technology [35].

Open-ended questions about respondents’ experiences of the benefits and challenges of reading health care professionals’ notes were used in order to collect qualitative data about the most relevant issues from the patients’ perspectives. The web-based questionnaire was dynamic; only respondents who reported having read the notes at least once (ie, had actual use experience) were asked the open-ended follow-up questions. If a respondent rated reading the notes as “not useful,” they were only asked about challenges (to avoid unnecessarily asking these respondents questions about benefits). The survey was available in both official languages of Finland: Finnish and Swedish.

The questionnaire was reviewed by 2 researchers in the field and 2 experts from the Social Insurance Institution of Finland, which was the organization responsible for developing My Kanta. In addition, we pilot-tested the questionnaire with 3 patients who filled in the questionnaire and simultaneously talked aloud about how they understood the questions. The questionnaire was subsequently revised to clarify wording.

Data were gathered during the period from June 4, 2021 to June 14, 2021 using a web-based questionnaire. Patient users of My Kanta in Finland received an invitation and a link to the questionnaire when they logged out of the patient portal. Thus, all respondents had used the patient portal just before they responded to the questionnaire. Participation was voluntary and anonymous.

The study protocol was reviewed and approved by the Ethical Review Board of Aalto University (ethics approval number D/957/03.04/2020 Nordic eHealth for Patients).

Descriptive statistics were calculated for quantitative data (respondents’ characteristics: age, gender, and portal usage). We performed content analysis (Atlas.ti, version 8.4.5; ATLAS.ti Scientific Software Development GmbH) on the responses to open-ended questions. One researcher first read through the data and used open coding to identify themes in the data without predefined categories. Short sentences were chosen as the analytical unit; themes were defined using in vivo coding, and to ensure that the themes represented the original meaning of the respondents, we used respondents’ sentences to label the themes. The number of respondents who mentioned a theme was calculated, and the themes were categorized. A second researcher then reviewed the results. The researchers discussed similarities and differences in themes and combined categories, until a version was agreed upon as the final version.

Of 449,922 users who logged in, 3139 users responded to the survey (response rate 0.7%). Most users reported either weekly (889/3112, 28.6%) or monthly use (1120/3112, 36.0%) (Table 1). The frequency of use was comparable to that of My Kanta in May 2019, when users used My Kanta on an average of 2.4 times per month [7]. The proportion of users over the age of 50 years was high (2681/3135, 85.5%). The proportion was 2-fold that in 2021 (44%). Although the frequency of use may vary notably between users, this may suggest overrepresentation of older age groups among respondents.

The total mean score for the System Usability Scale approximation was 72.7 (SD 15.9).

The most common reasons for visiting the My Kanta patient portal were viewing medical notes (978/3135, 31.2%), results of examinations (693/3135, 22.1%) or prescriptions (548/3135, 17.5%). Many people also visited the patient portal to renew a prescription (477/3135,15.2%), because there is no other method for renewing prescriptions electronically. At the time of the survey, COVID-19 vaccinations had started in Finland, and many (229/3135, 7.3%) logged into the patient portal to view their vaccination certificates. Other functions were used by only a few respondents (n=6-21). Some users (n=24) tried to use functions that did not exist, such as making appointments or checking their appointments (n=18), contact health care professionals (n=4), or looking for information about the reason that their prescription had not been renewed (n=2).

The most used functions were also deemed to be the most useful (Figure 1); for example, 96.4% (2511/2605) of users considered prescription renewal and 91.9% (2749/2992) of users considered viewing health care professionals’ notes to be very useful or somewhat useful; however, the majority of users also considered less rarely used functions useful, with the lowest percentage (759/1165, 65.2%) of users considering self-reported wellness data, and the highest percentage (1483/1759, 84.3%) of users considering living will to be very useful or somewhat useful.

Most respondents (2183/3135, 69.6%) answered the open-ended question and mentioned one or more benefits of reading notes (Table 2). Of the perceived benefits, most often respondents stated (560/2178, 25.7%) that notes supported remembering things:

Respondents often mentioned that they felt tense or overwhelmed during their appointment, and notes helped in remembering what was said and which instructions were received.

Respondents appreciated that notes provided information about their health and care. They were able to follow the course of their care and remain up-to-date. Furthermore, they wanted to identify doctors’ perceptions of them and their diseases. Several mentioned that it is important to have all the information concerning themselves:

Respondents also noted that the information is provided conveniently in one place, and they can check the information whenever they want. Notes were also perceived as helping them to understand their health conditions and what health care professionals had said during appointments. In addition, many respondents wanted to check the notes to ensure there were no errors or misunderstandings.

Many stated that the reason for accessing the information and remaining up-to-date was to actively self-manage their health. Respondents wanted to be aware of their care plans and to follow the course of their success. They subsequently prepared themselves for the next appointment and looked for further information related to their condition and care. A few commented that the notes helped in communicating with health care professionals and supported learning to express themselves, and 1046 out of 3135 (33.4%) respondents also discussed the notes with health care professionals.

One-third (1175/3135, 37.5%) of respondents also reported one or more challenges in reading notes (Table 3). The most commonly mentioned challenge was the difficulty in understanding the notes and the medical terminology. For example, one respondent stated:

Many mentioned that they used Google to interpret the unfamiliar terms, codes, and abbreviations, and they wanted plain language to be used instead.

However, the notes were not always available because there were delays in access and some visits were not recorded or visible. It was mentioned that it could take days or weeks before the notes were available, and some information was not available at all.

Many respondents perceived notes to be incorrect or inadequate. Most commonly, they were seen as having errors—some were not significant, such as a wrong date, but some were more severe, such as having a wrong diagnosis or another patient’s information. Respondents described,

and

Many also reported that the notes differed from what they had experienced themselves. Several also wished for more detailed notes. In contrast, some felt that it was unnecessary to include all personal details that they had mentioned during an appointment or the whole message that they had sent. One person also mentioned that they did not want to talk about certain issues, because they would be recorded and seen by all professionals.

Finally, there were challenges related to the usability of the system. Most commonly, it was mentioned that it was difficult to find information. The information was not always in chronological order, and some examination results were not linked to the appropriate appointments. A few respondents also mentioned that there is no interactivity in the system, and they wanted to comment on the notes or request corrections. Furthermore, it was noted that a patient should receive a notification when new information is available.

Respondents evaluated the My Kanta patient portal as useful and usable, which is consistent with the findings of earlier studies [20,21]. The total mean score for the System Usability Scale approximation was 72.7 (SD 15.9), which can verbally be described as good usability, according to Bangor et al [36,37]. Prescription renewal and viewing were indicated to be the most useful functions, but viewing medical notes and the results of examinations were the most frequent reasons for visiting the patient portals, which 91.9% (2749/3135) and 92.9 % (2770/3135) of respondents, respectively, considered useful.

Furthermore, respondents explained in their responses to open-ended questions that they appreciated having access to EHRs and information via a patient portal, which supports earlier findings [6,22]. Because My Kanta has been used nationally for several years, respondents were already familiar with the portal and actively used medical notes to prepare for their communications with health care professionals and to take care of their health.

The qualitative responses provided a rich and versatile description of the benefits of patient access to EHRs. Specifically, reading the notes was described as convenient, because they could be accessed easily and quickly, whenever suitable and at leisure. Therefore, easy access via patient portals may help patients to be engaged in self-management of their health. Reading notes were described as supporting remembering and understanding what health professionals said. They were able to check the state of health and care plans, remain up-to-date, look for further information, prepare for the next appointment, and ask further questions if something was unclear. We suggest that these activities support patients in learning about their disease or care, which motivates them to take care of their health.

Furthermore, reading notes can provide information that is not directly addressed during visits with a health care professional. As previously suggested [38], this may improve patient autonomy by reducing dependence on individual health care professionals and providing the opportunity to consult medical literature or other health care professionals to better understand health status and options for care or treatments.

Many respondents stated that it was important to be able to check the notes to identify potential errors and misunderstandings. They were also interested in professionals’ perceptions of their situations. Reading the notes was thus seen to help them understand what health care professionals had said and prepare for the next appointment. Thus, patient access to EHR supports patient–provider communication.

Very few patients were concerned about privacy or felt the notes were too personal or inappropriate. Some patients found incorrect information, and a few mentioned serious errors. It was very rarely mentioned, but a few respondents also felt that the notes included irrelevant information or personal information that was too detailed. Although rarely mentioned, the notes sometimes included information about very personal issues that patients were unwilling to share with all health care personnel. In particular, when a patient portal does not allow patients to correct errors or express their views with a comment, we presume that some patients may feel that their self-determination is violated.

It is noteworthy that respondents did not perceive reading the notes to be harmful per se but that challenges, such as understandability of medical terminology, incorrect or inadequate notes, missing information, or difficulties in finding information, interfered with the benefits of reading the notes. Finnish law requires that professionals’ notes are sufficiently comprehensive, clear, and understandable and that only commonly known terms or abbreviations are used [39]. Nevertheless, this is clearly not fulfilled according to the survey results.

In order to realize associated benefits, improvements in the quality and availability of medical professionals’ notes are needed. In addition to educating health care professionals, the availability of information can also be supported by providing a standard information structure. Because the information structure was confusing to patients, a standard structure would make finding and reading information easier from patients’ perspectives. It is important that the order of the notes is logical from their point of view and that examination results are clearly linked to corresponding appointments. Linking the notes to vocabularies and other information sources could also improve the understandability of medical terminology without increasing the workload of professionals. In addition, patient agency and trust could be supported by enabling them to add comments to their notes, mark some entries as sensitive, and control the visibility of entries.

This was a cross-sectional survey study examining patients’ self-reported experiences of the national patient portal in Finland, and the results may not be generalizable to other countries or patient portals. The survey was available only to My Kanta users after logging out of the patient portal. Not all users may have actively logged out the portal or noticed the invitation, which may have contributed to the low response rate. Thus, the results do not represent all My Kanta users or the population of Finland. A similar survey study in Sweden [5] also had a low response rate (0.61%).

In addition, the only demographic information available from the survey was age and gender; health and socioeconomic status of the respondents, literacy, and health literacy remained unknown. It is possible that the survey respondents represented users who were most interested in the patient portal and most capable of using it. Our sample did not include persons who had stopped using the portal or were not able to use it. Thus, nonrespondents may differ in their use of the patient portal and may experience barriers (eg, [40,41]) that were not identified in this study.

Moreover, My Kanta includes many functions that were recently added and, thus, not widely used. Therefore, the usefulness of all the functions could not be reliably evaluated. Furthermore, the portal does not have all the potentially useful functions that users could have experienced. As a few respondents complained, My Kanta does not have much interactivity—patients are not allowed to comment on notes or request corrections in the portal. In addition, the lack of notifications on added content frustrated respondents, because they often logged in to look for notes or test results that were not available yet.

By asking open-ended questions on the benefits and challenges, we improved the reliability of the answers as respondents reported their experiences using their own words and were not guided by having to choose from certain options. Because the number of respondents was high, the data that we collected were rich and versatile. However, respondents may have focused on the most significant benefits and challenges they experienced, and they may not have been able to verbalize those that were more abstract and less obvious. Therefore, we believe that our mixed methods survey study complements previous quantitative studies [5,6,19-23].

The main benefits experienced by patients were very similar to those identified in a smaller study [25] conducted at a single institution in the United States over a 12-month pilot period, in which participants reported that reading notes helped them to better remember next steps, provided positive emotions, and gave them faster access and results. The participants in the study [25] also valued the opportunity to correct any possible misunderstandings and give feedback to their providers, which are functions that patients also wished were available on My Kanta. In addition, Rexhepi et al [26] and Pyper et al [42] identified similar benefits, in studies in Sweden and the United Kingdom, respectively. Thus, our study provides further details in understanding self-management practices that patient access to EHR can support.

Moreover, several studies [6,20,24,26,27,42-44] have identified that some parts of medical records are difficult to understand. In addition, Johansen et al [14] found that 25.6% of administrative staff and 15.4% of health care professionals had received feedback from patients or their relatives regarding mistakes or missing information in their EHR. In our study, the number of serious mistakes was seldom mentioned, which was not the case in a recent US survey [45] with 29,656 respondents, in which 1 in 5 patients reported finding a mistake, and 40% perceived the mistake to be serious. It is possible that the number of respondents who found errors would have been higher in our study if we had specifically asked about this. This should be explored in future studies.

Pyper et al [42] also found that patients identified errors and omissions and had differences of opinion when they accessed electronic records for the first time. In this context, our study shows that unclear or inadequate notes are very common even when patients are familiar with use of the EHR and the challenges do not disappear when health care professionals gain experience in conveying information to patients. Thus, the findings support the need for applications that provide explanations of medical terms in EHR notes (eg, [46,47]).

Thus, patients’ basic needs and self-management processes seem to be similar regardless of the context—benefits and challenges experienced by patients are remarkably similar across countries, different health care systems, and EHRs.

Our findings indicate that patient access to EHR can support self-management—patients actively used medical notes to understand and remember what health care professionals said and to take care of their health. The challenges interfered with the benefits of reading the notes. In order to realize benefits, improvements in the quality and availability of medical professionals’ notes are needed, and patients should be encouraged to discuss their concerns with them. In addition, the availability of information can also be supported by using a standard information structure. Specifically, linking the notes to vocabularies and other information sources could also improve the understandability of medical terminology.
