Objective: To identify a spectrum of perspectives on functioning and health of patients with primary Sjögren's syndrome (pSS) from the five European countries in order to reveal commonalities and insights in their experiences.

Methods: A multicenter focus group study on the patients with pSS about their perspectives of functioning and health was performed. Focus groups were chaired by trained moderators based on an interview guide, audiotaped, and transcribed. After conducting a meaning condensation analysis of each focus group, we subsequently combined the extracted concepts from each country and mapped them to the International Classification of Functioning, Disability and Health (ICF).

Results: Fifty-one patients with pSS participated in 12 focus groups. We identified a total of 82 concepts meaningful to people with pSS. Of these, 55 (67%) were mentioned by the patients with pSS in at least four of five countries and 36 (44%) emerged in all the five countries. Most concepts were assigned to the ICF components activities and participation (n = 25, 30%), followed by 22 concepts (27%) that were considered to be not definable or not covered by the ICF; 15 concepts (18%) linked to body structures and functions. Participants reported several limitations in the daily life due to a mismatch between the capabilities of the person, the demands of the environment and the requirements of the activities.

Conclusion: Concepts that emerged in all the five non-English speaking countries may be used to guide the development and adaption of the patient-reported outcome measures and to enhance the provision of treatment options based on the aspects meaningful to patients with pSS in clinical routine.

Introduction

Primary Sjögren's syndrome (pSS) is an autoimmune disease of unknown etiology with female predominance that is characterized by an inflammation of exocrine glands, particularly salivary and lachrymal glands as well as variable extra-glandular manifestations such as musculoskeletal, gastrointestinal, and/or neurological symptoms (13). Patients with pSS can experience multiple facets of the mucosal dryness, pain, fatigue, and other complaints resulting in an impairment in everyday life and an altered health-related quality of life (HRQoL) (49).

Perceptions of the disease may not only differ between the patients and health professionals (10, 11), but also between individuals suffering from the same condition (12). This is majorly due to that the perception is built upon several mental sources that are implicit and specific to the individuals (13). A recent study in the psoriatic arthritis (PsA) highlighted the influence of cultural backgrounds on differences in the perception of illness (14). The illness perception is dependent on the disease activity, and negative views of the illness are linked to the worse future health outcomes (1517) whereas positive beliefs are associated with the better health outcomes (1821).

Patient-reported outcomes (PROs) represent the “voice of the patient” and are increasingly applied in the research studies and clinical practice to ensure a patient-centered care (22, 23). PRO Measurements (PROMs) are the instruments to measure PROs. Several PROMs are available for pSS, however, only a few of them have been validated (24). Besides, the patients from non-English countries rarely participate in the studies aimed at the development or validation of PROMs leading to the underrepresentation of the specific cultural context of these countries in the final PROM (25). PROMs are therefore often cross-culturally adapted only later after their development (25, 26). However, the cross-cultural adaption of PROMs is linked with challenges such as not being familiar with different cultures or not considering geographical variations and differences in the physical and social infrastructure. Thus, cultural equivalence is not always achieved (25, 2729).

An approach to truly capture what is important to the patients is qualitative methodology. It offers the opportunity to explore the perspectives, motivations, values, beliefs, and needs of the patients in a scientific and systematic manner. A qualitative approach supports the development of a deeper understanding of the patient perspective and enables the examination of complex issues that cannot be measured using strictly defined variables (30). The aggregation of views of the patients in a non-numeric, descriptive way can facilitate more patient-centered decisions (31) ultimately improving the quality of care.

Due to the increased relevance of the patient perspective (3), there is a growing body of qualitative evidence on the experiences of patients with pSS (7, 3236). Thereby, the general impact of pSS on (health related) quality of life (33) or daily life (32, 36) was studied and specific aspects of the disease like physical, mental or ocular fatigue (34), fatigue, sleep, and pain (35), sleep disruption (7) or treatment experiences (32) were evaluated. However, all of these previous studies were conducted on a national level. None of them examined the perspectives of patients with pSS from different countries in one study so far, focusing on a consistent data collection and data analysis and taking potential cultural, geographical, and social variations into account.

In this study, the main objective was to identify a spectrum of perspectives on the functioning and health of patients with pSS in the five European countries in order to reveal commonalities and insights in their experiences.

Patients and Methods

Study Design

We conducted a qualitative multicenter study using the focus groups (37) in seven rheumatology centers in five European countries, namely, Austria, Germany, Italy, Romania, and Sweden. The “COnsolidated criteria for REporting QUalitative research” (COREQ)—guideline provided by the EQUATOR Network was used for the reporting of this study (38).

Patients and Sampling

Patients with pSS had to meet the American–European Consensus Group Classification criteria, (6) and were recruited via telephone or face-to-face by the local investigators (BR, FB, TW, MD, MM, RD, CA, and PP) of the participating centers. Patients who already participated in another study at the same time or who had severe mental problems were excluded. Patients had to be fluent in the local language. We aimed to follow purposeful sampling by selecting patients of different ages and gender. However, pSS is predominantly affecting women (13, 39). According to the other qualitative studies in rheumatology (30, 40) and to balance the data quality and data quantity, we recruited two to four focus groups per country in order to gain data of enough richness.

Data Collection

All focus groups were chaired by the trained moderators at the local rheumatology centers: JU (female, PhD student, occupational therapist) for Austria, Germany, and Italy, RD and CA (males, PhD, medical doctors) for Romania and MM (female, Ph.D., physiotherapist) for Sweden. We developed a common interview guide, which was translated into local languages, back translated, pilot tested, and refined. Interview questions used in this study are depicted in the supplement files (Supplementary Table S1). If necessary, field notes were taken during the focus groups by the moderators. Each focus group was audiotaped and transcribed in the local language. Ethical approval was obtained in each center, and all the participants provided oral and written informed consent.

Data Analysis

The data analysis was carried out independently by the local researchers (JU for Austria, Germany, and Italy; RD for Romania; MM and CB for Sweden), using the method of meaning condensation (41). This involved the following four steps: first, local researchers read through all the focus groups transcripts and potential field notes of his/her center in order to become familiar with the data material. Second, specific units of a text, a few words, or a few sentences with a common meaning were identified in the data and defined as “meaning units”. Third, subconcepts contained in the “meaning units” were identified. A “meaning unit” could obtain more than one subconcept. Fourth, these subconcepts were grouped together to more comprehensive “higher-level” concepts, which were formulated by the local researchers in English language. A professional qualitative data analysis and research software known as Atlas.ti was used for the management of the data material (42).

After the focus groups were analyzed in each country, a one-day meeting with all researchers who conducted and analyzed the focus groups (JU, MM, and RD) was held. An experienced researcher (TAS) moderated this meeting, at which concepts from the five countries were compared and grouped together according to their meaning. Thereby, concepts representing the perspectives of the patients with pSS on functioning and health were identified. In order to describe these concepts in a standardized way with a common language, we used the International Classification of Functioning, Disability and Health (ICF) (43). This integrative biopsychosocial model, created by the WHO, is a highly recognized framework for classification that enables the description of problems of the patient, the selection of important outcome domains or the comparison of health information (43, 44). Hereinafter, two investigators (JU and AL) independently linked the concepts identified in the focus groups to the most precise ICF category according to the published linking rules (45). In case of any disagreement, the consensus was sought by discussion among the investigators.

Rigor and Accuracy of the Qualitative Data Collection and Analysis

In order to ensure rigor and accuracy of the study, we followed several approaches. A detailed draft of the study protocol was available for all the study members prior to the beginning of the study. We ensured that the local researchers had the required knowledge and conducted an extensive training and debriefing session before data collection. Furthermore, we established a detailed track record for the data collection process that determined important conditions for conducting the focus groups. After data retrieval, a pilot analysis was done by each local researcher (CB, MM, JU, and RD) before the full proper analysis was conducted. The whole process was supervised by a researcher with extensive experience in the field of qualitative research (TAS). Both investigators (JU and AL) who conducted the ICF-linking process were trained in linking concepts to the ICF.

Concepts Identified in the Focus Groups and Their ICF Linkage

The local investigators (JU, MM/CB, and RD) identified 184 subconcepts in Austria, 156 in Germany, 151 in Italy, 98 in Romania, and 103 in Sweden. After the one-day-meeting of the local investigators, the analysis of all focus groups resulted in 82 concepts meaningful to the patients with pSS. Out of these 82 concepts, the largest number of concepts (n = 25, 30%) was linked to the ICF component activities and participation. The second largest number of concepts (n = 22, 27%) was considered to be not definable or not covered by the ICF. These concepts contained general facets of pSS such as the difficulty obtaining a diagnosis, the uncertainty of the origin of the disease or that being ill is patience and energy demanding. Fifteen (18%) concepts were linked to the ICF component body functions and structures, another 13 (16%) concepts expressed environmental factors. The remaining seven (9%) concepts revealed insights in the personal thoughts, coping styles and behavior patterns of patients with pSS and were therefore considered as personal factors. The ICF components of the concepts are shown in Tables 26 (column 2).

Commonalities and Insights in the Lifeworld of People With pSS

Out of 82 concepts, 55 (67%) were mentioned by the patients with pSS in at least four of five countries and 36 concepts (44%) emerged in all the five countries. Tables 26 gives an overview of the 82 concepts meaningful to the patients with pSS with their specific ICF codes.

Participants from all the countries reported several limitations in daily life, including self-care, productivity, and leisure. The reasons for these limitations are characterized by a mismatch between the capabilities of the person, the demands of the physical, social, and cultural environment, and the requirements to conduct the activity. A participant in Austria explained the impact of her decreased fine motor skills on the performance of activities as follows: “…in the morning, opening milk bottles or juice, that was impossible (…), but for example I cannot do anything with buttons, I cannot make the buttons, jewelry. I cannot do the little things. (…) you have to look what you wear, I want to put on a nice blouse, but I cannot do this if he (husband) is not at home because of the buttons.” Another example is given by a participant in Italy who described her experience with her decreased ability to remember things: “I am no longer receptive, I was a great student in high school, but when I started at the university (…), I was not able to remember things. I do not know what was happening, you know, from 1 day to the other, I just did not have the ability to concentrate anymore. When I attended lectures for 4 h in the morning, I did not know what was going on.”

How the environment can lead to participation restrictions was mentioned in all countries. One participant in Sweden clearly described: “Everybody else can go to town to go shopping, I cannot go inside (in the store) because of those big fans at the entrance, it does not work, my eyes do not manage it (the flowing air) at the entrance. So I am left outside waiting in the car.”

The importance of social support and understanding from other people was highlighted by the participants from all the five countries. In addition, the participants mentioned comfortable feeling that is created by knowing other people with the same disease. A participant in Austria explained it in the following way: “I think you meet so many friends and gossip with them about something. And you can't deal with your own problems with others, because they have no idea. So you can meet people who are concerned, and if you just have a coffee and chat…”.

However, it was not always possible to join support groups due to long travel distances. Some patients with pSS described the negative impact of long travel distances that inhibit them from visiting a healthcare provider or joining the support groups. Similar, but different is the concept about the negative impact of having no access to the internet or living on the countryside for the development of knowledge about disease.

Patients with pSS explained that they not always felt taken seriously and understood by the health personnel. One participant in Austria described it as follows: “…when you go to the dentist, he doesn't care (…), your whole mouth hurts anyway, because you don't have any saliva, and then he gives you the cotton wool, which is not ideal if you don't have any saliva. If he takes it out, he'll rip half of your skin with it. And then you say to him already five times ‘Listen'. And if he is not aware of Sjögren and I say, 'Listen, I have a dry mouth, please, watch out!', but he doesn't care.” At the same time the participants from four countries mentioned that the time with health personnel at routine visits is not sufficient. Furthermore, they specified the absence of user-friendly information and pointed the risk of misjudging. However, the importance of having knowledge about the own abilities, the disease and its consequences for life was found to be meaningful by the patients with pSS of the four countries.

Discussion

To our knowledge, this is the first qualitative study on the European level that examined the perspectives of patients with pSS. We gained insights into the experiences of the patients with pSS from the Northern (Sweden), Central (Austria and Germany), and Southern/Eastern Europe (Italy, Romania). The results of our study highlight the importance of multinational data collection and go beyond previous small samples sized national studies, showing that the patients with pSS from different countries seem to experience similar challenges regarding their functioning and health. Concepts that expressed body functions and structures as well as concepts that were linked to activities and participation may be universal across the different European countries and might be used to guide the development and the cross-cultural adaption of the PROMs in pSS.

Our study led to the identification of 82 concepts; however, the largest number of concepts (n = 25, 30%) expressed aspects of an everyday living. This is in contrast to a study that aimed at exploring the perspectives of the patients with pSS on a national level (33), in which the concepts most often reported expressed the physical dimension of the disease. These differences may be explained by the multidimensional impact of pSS and the dynamic interaction between pSS, the affected body structures and functions and also the limitations in activities and restrictions in participation in relation to the personal and environmental factors.

Among the concepts found, the majority (67%) were mentioned by the people with pSS in at least four of five countries, and nearly half of the concepts (44%) were common in all the five countries. A similar observation was made in a recent study in which people with PsA from two different countries had two thirds of categories in common (14). In our study, two thirds of concepts assigned to body functions and structures (67%) and nearly half of the concepts related to the activities and participation (52%) were mentioned in all the five countries, indicating the importance of those two domains.

Some findings of our study are in line compared with other qualitative studies in pSS. We already know that the patients with pSS are confronted with a long way until diagnosis and thoughts about the origin of the disease and also the consequences of the disease on the physical, emotional, and social level (7, 33, 35, 36, 46, 47). We also know from other studies in pSS (33) and other rheumatic conditions that the patients sometimes feel that they are not taken seriously or that their complaints are dismissed by the health professionals (33, 46). The participants of our study specifically felt that the time the health personnel spent with them was insufficient. This is a notable result and should be seen in the context of ongoing debates about the future workforce requirements in rheumatology (48, 49). Current length of visits per patient and the time spent on the clinical care seem to be too short from point of view of the patients. Given that we expect an increasing lag between workforce supply and demand in the rheumatology in future, new concepts of care of pSS and other rheumatic patients might be needed.

Furthermore, attitudes toward drugs varied substantially between the participants of this study, either accepting them or feeling independent and having the desire to stop taking them. We do know from other studies that the attitudes toward taking drugs influence the adherence of the patients (50). Therefore, the health professionals should pay more attention to this point in order to ensure patient-centered care for the patients with pSS, also addressing non-pharmacological aspects and self-management strategies.

Our study has several limitations. First, we included a few European countries only. Considering the influence of social, cultural, and physical contexts into account, results might have been somewhat different if people from the other continents had participated in the study. On the other hand, we observed only few variations between the five countries (belonging to the Northern, Central, and Southern/Eastern Europe) studied, supporting the generalizability of our data.

Second, some concepts could have been influenced by the age, comorbidities, and other factors. Stratification of the focus groups according to these variables could have helped to measure the influence of these factors on the importance of the individual concepts. On the other hand, such an approach bore the risk that concepts emerged that are relevant for a small subgroup of the patients only. Our goal was to collect data representing the opinion and concerns of patients with pSS of everyday clinical practice and decided therefore against selecting patients according to the prespecified characteristics.

Third, the individual sample size in each country except Germany could have been bigger, however, saturation within the countries was reached that strengthens our results. We want to emphasize that the transferability of the identified lived experiences and perspectives is still limited, but a first attempt to investigate pSS with a cross-cultural understanding in order to inform practice and policy.

A specific strength of our study is that the health professionals with different occupations (occupational therapists, physicians, and physiotherapists) were involved in setting up the interview questions, analyzing and interpreting the data.

In conclusion, concepts meaningful to the patients with pSS identified in the five European countries might be used to guide the development and the adaption of PROMs. Concepts identified in this study enhance the clinical routine of the health professionals in order to provide support and treatment options based on the aspects relevant to the patients with pSS. However, the results of our study have to be considered preliminary and need to be confirmed by the future research.
