The present study was a multicenter survey conducted in the Multiple Sclerosis Center Dresden (Dresden, Germany), the Multiple Sclerosis Center Stuttgart (Stuttgart, Germany), and several neurological outpatient centers of NeuroTransData GmbH (Neuburg, Germany) between 2009 and 2010. Patients with clinically definite MS according to the McDonald criteria were asked to attend the survey in each participating center over a period of 2 weeks [34]. We targeted recruitment for a minimum of 500 fully completed questionnaires. Overall, 591 of 650 (90.9%) ambulatory MS patients who were asked to participate enrolled in the study. They were surveyed by the final version of the paper-based, self-developed questionnaire during outpatient clinic visits. Prior to study entry, each patient provided a written informed consent and was free to withdraw from the survey at any time for any reason without consequences on the care provided. Because this study involved minimal risk and no personally identifiable information, ethics committee approval was not required.

The 18 items in the questionnaire were developed by a scientific advisory board consisting of physicians, psychologists, and computer scientists. The questionnaire surveyed the frequency and nature of personal computer, website, email, and mobile phone use by MS patients, as well as demographic characteristics. Specifically, the questionnaire included 4 demographic items about age, sex, time since MS onset (in years), and residential area (by postal code) (items 1–4), 5 items about computer use (items 5–9), 5 items about Internet use (items 10–14), and 3 items about mobile phone use (items 15–17). We added 1 item about the respondent’s general attitude toward using new media for communication with health care providers (item 18) (see Multimedia Appendix 1).

Patients were assigned to the rural area group (population of place of residence <100,000) or to the city group (population of place of residence ≥100,000) based on postal code (questionnaire item 3) [35,36]. We determined disease duration (in years) by calculating the difference between MS diagnosis (questionnaire item 4) and the year of study entry. Use of each medium at least once a week indicated a sufficient frequency for future communication with health care providers. New media acceptance was reported for patients accepting at least one of three types of new media (website, email, and mobile Internet application or short message service) for communication with health care providers. To analyze the influence of age on the a priori use of each medium, we grouped respondents by a median split (younger half: 17-40 years, n = 283; older half: 41-73 years, n = 298).

All statistical comparisons were 2-tailed, and a P value of <.05 indicated statistical significance. We used IBM SPSS version 19.0 (IBM Corporation, Somers, NY, USA) for all statistical computations. Acceptance was evaluated by a logistic regression model for each new media type (website, email, mobile Internet application or short message service) using demographic variables and items of specific media type and reporting goodness of fit (Hosmer-Lemeshow test; chi-square) and effect size (odds ratio). Differences in categorical variables were assessed with a chi-square test for between-participants effects and with McNemar test for matched pairs.

In the statistical analysis, we included 586 of 591 MS patients who submitted answers to the last survey question (questionnaire item 18). The majority of study patients were female (408/586, 69.6%) with a mean age of 40.93 (SD 10.84) years (5 missing answers), comparing well with typical population statistics of patients with MD [37]. A total of 6 in 10 patients (336/586, 57.3%) lived in a city area with a population of 100,000 people or more. The disease duration averaged 8.60 (SD 6.52) years since onset (7 missing answers). In all analyses, we observed no impact of residential area (rural area, town, or city) on any item response. Furthermore, patients did not differ between states of the former German Democratic Republic (Saxony) and the Federal Republic of Germany (Baden-Württemberg).

The vast majority of MS patients (558/586, 95.2%) had access to a computer and 75.4% (442/586) of them personally owned one (Table 1); 70.8% (415/586) used it daily and 91.1% (534/586) used it at least weekly. Men reported higher rates of general use (P < .001), computer ownership (men: 151/178, 84.8%; women: 291/408, 71.3%; P < .001), and experience in the installation of new software (men: 144/178, 80.9%; women: 231/408, 56.6%; P < .001). Nevertheless, computer use was widespread among women. Most patients (509/586, 86.9%) reported acquainting themselves quickly with new software. Younger MS patients tended toward a greater (P < .001) and more diversified use of computers (emailing: P = .003; browsing the Internet: P = .007; chatting: P < .001; having already installed new computer programs: P < .001; and becoming quickly acquainted with new computer programs: P < .001). In all subgroups of MS patients, about 40% (62/178, 34.8%, to 170/408, 41.7%) reported using a computer to retrieve information about their disease. All results are summarized in Multimedia Appendix 2.

About 94% of MS patients (551/586) reported they had Internet access (Table 2). Men browsed websites more frequently (P = .009), whereas the number of male and female nonusers was similar. The pattern was the same in the case of reading emails (P = .002) and sending emails (P = .03). Young MS patients more frequently than older patients performed tasks such as browsing (P < .001), chatting (P < .001), and emailing (reading: P = .02; sending: P = .004). MS-related information seeking was reported by between 35.2% (105/298) and 38.9% (110/283) among all subgroups of MS patients. A small number of patients had already communicated with their physician (22/586, 3.8%) or with other patients (29/586, 5.0%) via the Internet (Table 2).

Nearly all MS patients possessed a mobile phone (553/576, 96.0%) but older patients used it less frequently (P < .001) and less extensively (calling: P = .002; text messaging: P < .001; browsing websites: P < .001; reading or sending emails: P = .001; and scheduling: P < .001) (Table 3). Women showed a greater tendency for text messaging (P < .001) but men were more likely to operate smartphone abilities such as browsing websites via mobile Internet (P = .01) or scheduling appointments (P = .03).

When asked about the acceptability of using various modes of communication, including electronic communication devices, for receiving information and guidance from their physician for managing their MS, 20.5% (120/586) of MS patients accepted communication by mobile phone Internet application or short message service, 41.0% (240/586) by website, 54.3% (318/586) by email, and 67.8% (397/586) by at least one of these modes of communication (Table 4). The majority of patients (539/586, 92.0%) found existing traditional methods acceptable. Acceptance of email services for this purpose exceeded the acceptance of telephone conversations (263/586, 44.9%; P = .007). Women were more likely to accept communication by telephone (P = .01).

We included media-specific items and demographic variables in all cross-sectional logistic regression models resulting in admissible model fits (Hosmer-Lemeshow test for email: χ² ₈ = 7.0, P = .54; for websites: χ² ₈ = 6.7, P = . 58; and for mobile phone features: χ² ₈ = 9.2, P = .32). Neither sex nor age had an impact on the acceptance of any type of electronic communications media. We eliminated duration of disease from the analyses to avoid multicollinearity, since it was highly correlated with age.

In general, patients with regular a priori use of new electronic media were more likely to accept this form of communication with health care providers (Table 5). More specifically, reading emails at least once a week, browsing Internet websites at least several times a week, and using a mobile phone daily raised the level of acceptance significantly.

Furthermore, online health information seekers (odds ratio 2.4) and patients having already communicated with their physician through a website (odds ratio 3.3) showed a greater interest in website-based communication (Table 5). Scheduling appointments on a mobile phone (odds ratio 2.1) was the only specific task that raised the likelihood of accepting mobile phone features for communication with health care providers.

The vast majority of MS patients had access to a computer or owned one themselves. They were regularly visiting websites, and reading and writing emails, and possessed a mobile phone, consistent with results of smaller MS-focused studies [26,31]. The number of Internet users was slightly higher than in more general reports from the Pew Internet & American Life Project [4] but corresponded to the number from Lejbkowicz et al [31]. In agreement with Green et al [38], our study found less-intensive and less-diversified use of computers and Internet services among older people. Our results indicated that women used computers, the Internet, and email services less often, but the prevalence of female nonusers was similar to that of male nonusers. Similarly, Kummervold et al [6] reported an increasing use of the Internet by females in Europe between 2005 and 2007. Mobile phones were the most commonly used devices. As anticipated, young male patients were more likely to use smartphone abilities such as mobile Internet or appointment scheduling.

In our study, 4 in 10 MS patients were already using the Internet regularly for health information seeking and other disease-related tasks. In comparison, 56% to 61% of Americans searched online for health information [3,4]. However, differences between study findings in the use of eHealth services by chronically ill patients may be due to how the studies define media use as described by Wagner et al [39], indicating that 11% accessed health information services at least monthly but 45.9% had ever used them in the previous year [2]. Several European studies noted an increasing rate of Internet use for health purposes, with the highest increase being in Germany (from 44.4% in 2005 to 56.6% in 2007) [6,8,9]. In contrast to Santana et al [8], we did not find any differences in the use of new media with respect to place of residence.

In contrast to Hay et al [11], who reported that 82% of MS patients retrieved medical information online before the first visit, our rates were lower. Lejbkowicz et al [31] observed that 63% of MS patients used the Internet for MS-related tasks, but they did not state how they obtained that information. Nonetheless, only a minority of MS patients used the opportunity to correspond with their physician or other patients via the Internet. Although other studies reported similar results, evidence for increasing interest in online health care services is growing [2,6,8,9,40].

In addition to the a priori use of electronic communication devices, we investigated the a priori attitude toward adopting these services for aiding in MS disease management. Most participants accepted more than one type of new media for communication with health care providers. Communication via email and website was considered as acceptable as conventional telephone calls. A notable proportion of patients perceived the integration of mobile phones and mobile Internet to aid their therapy as useful. Two-thirds of MS patients were willing to use at least one new media service for communication with health care providers. The main factor in accepting a service was a priori use. Patients who read emails at least once a week, browsed websites several times a week, and used a mobile phone daily were more likely to approve a type of communication. Likewise, current users of electronic communication devices for health care management showed a greater interest in Web-based communication.

Several studies support the open-mindedness of patients toward using email communication in disease management. Hassol et al [16] reported that patients who used electronic health records generally preferred emails to telephone calls. In a study focusing on older patients, Singh et al [40] found that 49.3% of them could imagine using emails for communication with their physician. In agreement with our findings, a priori use of email services was the best predictor for acceptance of email communication with health care providers [40]. Santana et al [9] reported that about 18% of Europeans usually contact their physician via Internet and 25% would like to make their appointments online. Moreover, 4 out of 10 people in Europe would select their physician with regard to eHealth services provided [9]. Similarly, 49% of Israeli MS patients welcomed the opportunity to communicate with their medical team online [31].

Some limitations of our survey warrant consideration. Participation in the survey was nonrestricted and hence may have introduced selection bias by motivation or interest. However, this was minimized by the large number of participants. Moreover, relevant demographic data, such as income or ethnicity, that other studies had used were lacking in our survey. Therefore, we were unable to test assumptions about potential obstacles posed by new media such as the digital divide. As income is a sensitive issue, participants may not have been willing to specify their personal particulars. We conducted our survey using paper-and-pencil questionnaires to avoid selection bias. Differences in the methods of similar studies in defining and assessing media use are important when attempting to compare studies on the use of health care information and communication technology. The questionnaire provided only a single item for the acceptability of new communication methods with health care providers, which may have been insufficient to obtain nuance and detail about the patients’ true attitudes. We surveyed attitudes toward electronic communication devices but lacked data on actual behavior or objective use.

In our survey, we obtained data on the a priori use of new media by chronically ill patients with MS, as well as their attitudes toward future use of new media for communication with health care providers and differentiating between common communication types.

To summarize, our results indicate that the majority of MS patients are willing to use new media for further eHealth implementations. Although the potential benefits (and risks) of using electronic communication devices in MS health care services remain to be established, our data suggest these tools can be integrated with electronic health records and patient relationship management systems in order to increase the range of potential users and capabilities.

We agree with Nijland et al [41] that delivering high-quality health care to patients in as many suitable ways as possible should make a significant impact on the design of eHealth applications. eHealth services such as patient relationship management systems and electronic health records that focus on only a single communication type will miss the chance to maximize their effectiveness for use in the health care process. According to our findings, there are two gaps. First, although 40% to 50% of patients would like to use eHealth services to aid their therapy, only 5% of patients currently use them. Second, 90% of patients are technically skilled enough to use information and communication technology but only 50% are willing to use health information and communication technology. To overcome these obstacles, the design and implementation of eHealth applications in the health care process have to be tailored to patients’ individual needs. Further research should focus on educational content as well as on technical options to deliver the content to those who would benefit from it.
