The prospective survey was distributed via social media (Twitter, Instagram and Facebook), QR code and email. Descriptive statistics were calculated, and regression analyses were performed to show correlations. **Results** We analysed the responses of 299 patients and 129 rheumatologists. Most patients (74%) and rheumatologists (76%) believed that DHAs are useful in the management of rheumatic and musculoskeletal diseases (RMDs) and felt confident in their own usage thereof (90%; 86%). 38% of patients and 71% of rheumatologists reported that their attitude had changed positively towards DHAs and that their usage had increased due to COVID-19 (29%; 48%). The majority in both groups agreed on implementing virtual visits for follow-up appointments in stable disease conditions. The most reported advantages of DHAs were usage independent of time and place (76.6%; 77.5%). The main barriers were a lack of information on suitable, available DHAs (58.5%; 41.9%), poor usability (42.1% of patients) and a lack of evidence supporting the effectiveness of DHAs (23.2% of rheumatologists). Only a minority (<10% in both groups) believed that digitalisation has a negative impact on the patient–doctor relationship. **Conclusion** The COVID-19 pandemic instigated an increase in patients’ and rheumatologists’ acceptance and usage of DHAs, possibly introducing a permanent paradigm shift in the management of RMDs. * COVID-19 * epidemiology * health services research * patient reported outcome measures ### Key messages #### What is already known about this subject? * During the COVID-19 pandemic, many consultations had to be cancelled or were switched to a virtual format. * This study analyses the use and perception of digital health applications (DHAs) by rheumatic and musculoskeletal disease (RMD) patients and rheumatologists in Germany. #### What does this study add? * Patients and rheumatologists consider DHAs to be useful in the management of rheumatic diseases. * The attitude towards DHAs has improved, and implementation has increased due to COVID-19. * Patients and rheumatologists prefer synchronous monitoring, as opposed to flexible asynchronous monitoring. * A lack of information about suitable DHAs was the greatest barrier for DHA usage among RMD patients and rheumatologists. #### How might this impact on clinical practice? * In stable disease conditions, virtual visits can be implemented for follow-up appointments. * The increased availability of information on DHAs, as well as our growing experience with their implementation, will likely cause a steady and lasting increase in DHA usage in rheumatology. ## Introduction Rheumatic and musculoskeletal diseases (RMDs) are complex chronic conditions that require regular monitoring and treatment. Once an RMD has been diagnosed, regular disease follow-up is necessary. This includes the assessment of treatment response, symptom tracking, blood exams, monitoring for adverse events and re-evaluation of treatment indications. The COVID-19 pandemic presents an unprecedented challenge to public health in general, and, in particular, in the care of the chronically ill patients. At the beginning of the COVID-19 pandemic, severe changes and cuts in rheumatological care were made.1 2 Due to pandemic containment measurements, many patient appointments had to be cancelled3 or were converted to telephone or video consultations.2 4 5 Many practitioners believe that telemedicine holds great potential for the management of RMDs.6 Digitalisation now affects 90% of the healthcare system and has already led to many changes for both patients and doctors, crucially impacting the patient–doctor relationship.7 It has already been shown that rheumatology patients are willing to use mobile health technologies to improve their disease status and to track symptoms and disease activity.8 9 Also, the use of digital health applications (DHAs) by rheumatologists has increased over the past years.10 Even though studies demonstrating positive effects of applications (‘apps’) in the field of rheumatology are still lacking,11 the process of DHA implementation in routine healthcare is expected to be further accelerated by the introduction of the Digital Health Care Act, which grants all those with statutory health insurance in Germany the reimbursement for certain DHAs.12 For the successful development and implementation of telemedical concepts for the management of RMDs, both the patient’s and the rheumatologist’s perspective are crucial.13–15 The main question is if and how adequate treatment can take place digitally in the future. This survey addressed this question by examining the usage and perception of digital health applications (such as video consultations, medical apps, digital appointments, diaries, questionnaires, online courses or the use of symptom checkers) by RMD patients and rheumatologists in Germany. In particular, changes in regard to these aspects during the COVID-19 pandemic were recorded. ## Methods The web-based survey was created by members of the Working Group Young Rheumatology (Arbeitsgemeinschaft Junge Rheumatologie) and the German League against Rheumatism (Deutsche Rheuma-Liga Bundesverband e.V.). An online expert panel identified three areas of interest to investigate: (1) usage of DHAs, (2) DHA preferences and (3) DHA barriers and advantages. In order to investigate the identified areas of interest, an expert panel designed a questionnaire in analogy to the EULAR recommendation task force standard operating procedures16 in two separate online meetings after individual literature research. After both meetings, the questionnaire was shared with members of the German League against Rheumatism who commented on and edited the draft version and approved the final questionnaire (online supplemental material 1). ### Supplementary data [[rmdopen-2020-001548supp001.pdf]](pending:yes) The web-based survey (SurveyMonkey Inc) was accessible from 9 September 2020 to 15 October 2020 and distributed via social media (Twitter, Instagram and Facebook) (online supplemental material 2), a QR code and/or email. All patients with self-reported RMDs and rheumatologists (specialists and trainees) were eligible. All participants gave consent. There were no exclusion criteria. ### Supplementary data [[rmdopen-2020-001548supp002.pdf]](pending:yes) Reporting the study’s methodology and results was done according to the Checklist for Reporting Results of Internet E-Surveys.17 Descriptive and summary statistics were used. The analyses were performed using IBM SPSS Statistics V.20 Windows (SPSS Inc, Chicago, Illinois, USA) and Excel Windows (Microsoft GmbH, Unterschleißheim). Absolute and relative frequencies were calculated and depicted in tabular and graphical form. Regression analyses were performed to show correlations. ## Results Two hundred and ninety-nine patients and 129 rheumatologists completed the online survey. The mean age of participating patients was 49 years (15–82 years), and the majority was female (n=239, 79.9%). Various RMDs were reported by participating patients, with rheumatoid arthritis (RA) being the most common disease (n=134, 44.8%). A percentage of 74.6 (n=223) of patients reported to use apps several times a day on a smartphone, 14% (n=42) used apps once daily and 3.7% (n=11) once weekly. Only 4% (n=12) of the patients stated to never use apps. The physicians’ genders were balanced (48.5% (n=63) female). A percentage of 74.1 of rheumatologists were clinicians (46.1% (n=59) in a university hospital, 28.1% (n=36) in a non-university hospital) and 25.8% (n=33) worked in a private practice. Participant details are given in tables 1 and 2. View this table: [Table 1](http://rmdopen.bmj.com/content/7/1/e001548/T1) Table 1 Patients characteristics (mean±SEM or n (%)) View this table: [Table 2](http://rmdopen.bmj.com/content/7/1/e001548/T2) Table 2 Physicians charactersitics (n (%)) ### Usage of digital health applications Ninety per cent (n=269) of patients stated that they were able to use DHAs (table 3) and 74.2% (n=222) described the usage as useful for managing their disease, whereas 2.7% (n=8) disagreed. The higher the age of patients, the lower the overall app usage (beta=0.312; R²=0.097; p=0.001) and the lower their confidence in using apps (beta=−0.195; R²=0.038; p=0.001), adjusted for gender and travel time to their rheumatologist. View this table: [Table 3](http://rmdopen.bmj.com/content/7/1/e001548/T3) Table 3 Usage of digital health applications before and after COVID-19 pandemic, n (%) Seventy-six per cent (n=98) of rheumatologists described the use of DHAs for managing the patient’s disease as useful; only 1.6% (n=2) disagreed. A percentage of 85.5 (n=110) of physicians stated that they are able to use DHAs (table 3). No significant difference in gender, age, degree of training and workplace was noted. Due to the COVID-19 pandemic, the attitude towards DHAs changed positively in 37.5% of patients (n=112) and 71.3% of rheumatologists (n=92). Twenty-nine per cent of patients (n=88) and 48.1% of rheumatologists (n=62) reported using DHAs more regularly (table 3). ### DHA preferences At the time of the survey, informative DHAs (63.2%, n=189) and symptom checkers (40.5%, n=121) were most often used by patients. Digital disease-related questionnaires, diary DHAs and therapy DHAs, as well as video consultations, were planned to be used more often/frequently in the future. Self-collected blood samples at home with digital access to results showed different levels of acceptance: 51.2% of patients (n=153) reported no interest and 43.5% (n=128) could imagine the usage of this technique in the future (details are given in figure 1). ![Figure 1](http://rmdopen.bmj.com/https://rmdopen.bmj.com/content/rmdopen/7/1/e001548/F1.medium.gif) [Figure 1](http://rmdopen.bmj.com/content/7/1/e001548/F1) Figure 1 Usage or recommendation of digital health applications. Patients and rheumatologists were asked to indicate the specific digital health applications (DHAs) they used or were recommended. Potential DHAs include digital information, symptom checkers, digital diaries, therapy and questionnaires, blood collection at home and video consultations. The percentage of patients and rheumatologists who indicated one of four levels of usage (planned, currently used, already used prior to COVID-19 or no interest) is shown. Most frequently, patients stated that video consultations are possible for follow-up (40.6 %, n=71) and emergency appointments (38.3 %, n=67). A percentage of 58.9 (n=176) of the patients affirmed that time-synchronous digital consultation could complement physical appointments (figure 2). ![Figure 2](http://rmdopen.bmj.com/https://rmdopen.bmj.com/content/rmdopen/7/1/e001548/F2.medium.gif) [Figure 2](http://rmdopen.bmj.com/content/7/1/e001548/F2) Figure 2 Potential usage of video consultations in per cent. Rheumatologists and patients were asked about perceivable purposes of video consultations. In addition, 81.3% (n=243) of patients and 85.3% (n=110) of rheumatologists reported to be willing to skip an on-site appointment if the patient’s disease is stable and he or she could indicate his or her well-being by using a DHA (figure 3). ![Figure 3](http://rmdopen.bmj.com/https://rmdopen.bmj.com/content/rmdopen/7/1/e001548/F3.medium.gif) [Figure 3](http://rmdopen.bmj.com/content/7/1/e001548/F3) Figure 3 Percentage of rheumatologists and patients who are/are not willing to skip a real-life appointment and substitute it with a digital health application (DHA) in stable disease. Agreeing rheumatologists and patients were asked if they prefer time-synchronous or time-asynchronous DHAs. ### Barriers and advantages of DHAs The effect of digitalisation on the patient–physician relationship was described variably, with 26.8% (n=80) of patients evaluating it positively and 10.7% (n=32) negatively, while 10.4% (n=31) stated no influence. The majority described both positive and negative aspects of digitisation on the patient–doctor relationship (42.1%, n=126). A comparable trend was seen among rheumatologists. A percentage of 48.1 (n=68) described positive and negative aspects of digitisation. A percentage of 32.6 (n=42) stated a positive and only 8.5% (n=11) a negative attitude. Details are given in figure 4. ![Figure 4](http://rmdopen.bmj.com/https://rmdopen.bmj.com/content/rmdopen/7/1/e001548/F4.medium.gif) [Figure 4](http://rmdopen.bmj.com/content/7/1/e001548/F4) Figure 4 Rheumatologists’ and patients’ attitudes towards digitisation and its effect on the patient–doctor relationship in per cent. Most frequently, both positive and negative aspects of digitisation were reported by rheumatologists and patients. Too little information concerning suitable DHAs was the most mentioned barrier in using DHAs, affirmed by 175 patients (58.5%) and 54 rheumatologists (41.9%). Second, patients stated the lack of usability (42.1%, n=126), whereas rheumatologists remarked too little evidence for the benefits of DHAs (23.3%, n=30). Other barriers were poor quality, concerns about data protection, high costs and the lack of suitable equipment (such as a poor internet connection or old devices). Only 7 rheumatologists (5.4%) and 27 patients (9%) stated no need because of satisfaction with current analogous solutions. The most mentioned advantage of DHAs by both physicians and patients was the ability to use them independently of location and time of day and the subsequent flexibility. Additional advantages include detailed documentation, cost-saving, more opportunities to provide information, diagnostics and therapy, as well as better preparation for the patient–doctor discussion. Only 18 patients (6%) and 1 rheumatologist (0.8%) did not see any advantages of DHAs (details are indicated in table 4). View this table: [Table 4](http://rmdopen.bmj.com/content/7/1/e001548/T4) Table 4 Advantages and barriers of DHA, n (%) ## Discussion We reported findings from a conjoint survey assessing both patients’ and physicians’ perspectives on digitalisation in rheumatology during the COVID-19 pandemic. The survey explored themes relating to: (1) the usage of digital health applications (DHAs), (2) preferences for specific DHAs and (3) the perceived advantages and barriers of DHAs. In this survey study, numerous patients and rheumatologists reported a positive attitude and increased usage of DHAs due to the COVID-19 pandemic in Germany. In line with previous patient surveys,9 the majority of patients stated that they regularly used mobile apps on their smartphone, believed that they were able to use DHAs and that using DHAs was beneficial for managing their RMD. Interestingly, in contrast to rheumatologists, the majority of patients indicated that they used symptom checkers. This technology enables a low-barrier digital health check to assess disease symptoms. Frequent use could reflect patients’ increased need for security. However, there is still little evidence to support the positive benefits of symptom checker usage. This might explain the reported reluctance of rheumatologists in recommending symptom checkers to their patients.16 Both groups showed an increased interest in the implementation of digital therapies to complement conventional therapies, that is, educational online courses. However, noteworthily, these resources were, at the time of the survey, rarely used, indicating the need for better quality material and the effective promotion of existing programmes. To reduce infection risk during consultations and to save time and clinic resources, self-administered blood tests in combination with digital monitoring might complement clinical practice in the future.18 19 Gossec *et al*20 were able to demonstrate that wearable data was able to predict disease flares in RA and axial spondyloarthritis (SpA) patients. Furthermore, the feasibility of CRP quick tests for a rapid on-site disease activity assessment was shown in SpA patients.19 However, patients were somewhat reluctant to use applications such as self-administered blood tests or wearables for disease monitoring in the future. This may be because many of these solutions are concepts that currently remain foreign to the patient and/or raise concerns about digital overload and potential data violation. Due to COVID-19 containment measures, many physical appointments had to be postponed or were changed to telehealth consultations. In line with the literature, the majority of rheumatologists and patients reported that follow-up appointments were most suited to video-consultations, as were emergency appointments.1 21 Noteworthily, most patients were interested in the concept of video consultations; however, only a minority had previously engaged in one (6.7%). Consequently, of all listed DHAs, rheumatologists reported the greatest COVID-19 induced uptake for video consultations. A majority in both groups indicated that they would be willing to skip an on-site appointment if the patients were able to indicate their well-being via a DHA. Interestingly, the analysis showed that synchronous monitoring via telephone or video consultation was, in both groups, preferred to flexible asynchronous monitoring, for example, via digital questionnaires. These findings are supported by a pre-COVID-19 study by Ferucci *et al*.22 The authors reported few differences between outcome and quality of care for patients with RA treated with telemedicine compared with physical follow-up treatment, concluding that it is reasonable to incorporate telehealth into routine care for patients with RA. An important aspect for the use and acceptance of digitalisation in medicine is the impact these technologies have on the patient–doctor relationship.23 In principle, our survey showed a positive trend in the perception of digitisation and its influence. Only the minority (0.7% of patients and 8.5% of physicians) saw potential negative effects. However, the majority in both groups currently stated a mixed perception of this topic. Unfortunately, the different aspects of this topic were not further specified in the survey. However, the loss of physical contact for examinations and difficulties in establishing an emotional relationship is regarded as a disadvantage by some authors (‘emotional and physical gap’).24 Furthermore, some patients, especially the elderly or those with a poor socioeconomic background, may not have the equipment and skills to use telehealth solutions, causing a digital divide based on age and income.1 However, the use of digital tools offers both sides a variety of new opportunities, such as new ways of communication and knowledge exchange (ie, via social media),25 new possibilities for identifying diagnoses,26 27 personalised treatment and disease monitoring via digital tools (such as apps or wearables),28 as well as an efficient and simple exchange of electronic information for both clinical and scientific purposes.6 29 Almost all patients and rheumatologists identified advantages in using DHAs: implementation independent of time and place and general flexibility were stated most often. Interestingly, in contrast to 46 patients (15.4%), no rheumatologist thought that DHAs might help in the preparation of a face-to-face appointment. Similar to previous surveys, the main barrier was a lack of information concerning suitable DHAs.13 For patients, the second greatest barrier was poor DHA usability, while for rheumatologists, it was too little evidence supporting DHA usage. This highlights the need for DHA studies, as expressed previously.12 30 To ensure high usability, it is advisable to integrate patients in the early phases of DHA development.11 Unsatisfactory DHA skills were rarely stated as a barrier, similarly to costs. The online format of our survey enabled broad accessibility to a potentially diverse sample of RMD patients and physicians. Due to the completely anonymous nature of the survey, the response rate could not be measured. The online nature of our survey, however, also potentially introduces a selection bias for digitally inclined users. The data collection transpired entirely digitally; therefore, patients and doctors with lower technical or digital competencies may have been missed. Lack of internet access or the availability to a modern smartphone was also identified as an issue regarding the German COVID-19 tracing app.31 32 The interpretation of the digital survey results should therefore be carried out cautiously, as we cannot entirely exclude the possibility that not all RMD patients (especially the elderly) were able to participate in the survey. The survey was conducted between 9 September and 15 October. During this time, Germany was in the phase between the first and the second European COVID-19 waves. The results should therefore be carefully interpreted in the context of this timeframe. It can be assumed that the acceptance will continue to change, as the use of telemedicine services is likely to further increase in the future due to ongoing pandemic containment measures. To our knowledge, this is the first conjoint analysis assessing both patient and physician perspectives on digitalisation in rheumatology during the COVID-19 pandemic. Patient representatives were involved at all stages. We believe that our results may guide future recommendations, research and, most importantly, clinical practice. Our results highlight the current need for clinical studies and, in preparation for these studies, the implementation of guidelines for the use of telemedicine in rheumatology.11 ## Acknowledgments The authors would like to thank the following persons and societies for their great effort, distributing the online survey: P Aries, A Hueber, E Feist, C Fiehn, P Korsten, I Kötter, F Mühlensiepen, A Pfeil, M Rudwaleit, M Welcker, S Zinke, Deutsche Vereinigung Morbus Bechterew e.V., Deutsche Rheuma-Liga Bundesverband e.
