An interactive web-based programme on relapse management for people with multiple sclerosis (POWER@MS2) - development, feasibility, and pilot testing of a complex intervention.

Introduction: Despite the lack of high-quality evidence regarding its long-term effectiveness, intravenous corticosteroid therapy is recommended as the standard treatment of acute multiple sclerosis relapses in Germany. High financial expenses and the equivalent effectiveness of oral corticosteroid therapy contrast with this trend. There is an urgent need to provide patients with evidence-based and comprehensible information on relapse management and to actively involve patients in relapse treatment decisions. Web-based decision support on relapse management could be an effective measure to empower people with multiple sclerosis making informed treatment decisions. Objectives: To develop a web-based programme on relapse management for people with multiple sclerosis and evaluate the feasibility and acceptability of the intervention. Methods: The study followed the first two phases of the UK Medical Research Council Framework for complex interventions. The first phase involved the development of an interactive web-based programme on relapse management. The second phase focused on the feasibility and pilot testing of the programme with people with multiple sclerosis and experts with a professional background in multiple sclerosis. Data was obtained using questionnaires with closed- and open-ended questions as well as qualitative semi-structured telephone interviews. Quantitative data was analyzed descriptively, whereas qualitative data was clustered by topic. Results: Feasibility of the intervention programme was tested with 10 people with multiple sclerosis and 10 experts. Feasibility testing indicated good practicability and acceptance of the content. After revision, the programme was piloted with seven people with multiple sclerosis and three experts. The results showed good acceptance in both groups. Based on the feedback, a final revision was performed. Conclusion: Feasibility and pilot testing indicated good user-friendliness, acceptance, and practicability of the programme. The programme is currently evaluated in a randomized controlled trial (Registration Number on ClinicalTrials.gov: NCT04233970). It is expected that the programme will have a positive impact on patients' relapse management and strengthen their autonomy and participation.

Experiences of persons with Multiple Sclerosis with lifestyle adjustment-A qualitative interview study.

BACKGROUND: Persons with Multiple Sclerosis (pwMS) follow individual strategies to cope with this highly heterogeneous disease. As surveys show, lifestyle habits play an important role in pwMS. However, little is known about individual experiences of pwMS with different lifestyle adjustment strategies. OBJECTIVE: This study aims to describe and understand individual experiences of pwMS with lifestyle adjustments. METHODS: Semi-structured interviews were conducted with 50 pwMS in Germany. Criteria for inclusion were age ≥ 18 years and a diagnosis of relapsing-remitting Multiple Sclerosis. Data were analyzed inductively and deductively according to a six-step thematic analysis. RESULTS: The three main themes for experience-based lifestyle adjustments were: 1) nutrition and supplements, 2) exercise and physical activity, and 3) stress management. Influencing factors on the decision-making process such as active disease management, information and advice, desire for mental health and social support, and the wish for self-determination were identified. Impacts of starting or maintaining lifestyle habits included, for example, MS-specific, general, and mental health benefits, the development of coping strategies, social support, and barriers that led to a termination of lifestyle adjustments. CONCLUSION: This study provides a rich and nuanced amount of experiences of pwMS with lifestyle adjustments and leads to three important conclusions: 1) Further research is warranted to better describe the perceived effects of lifestyle habits on MS symptoms and progression, in particular with regard to nutrition and stress reduction; 2) patient education in MS should include the available evidence on lifestyle management and 3) patients need to be actively supported in changing their lifestyle behavior.

Understanding Magnetic Resonance Imaging in Multiple Sclerosis (UMIMS): Development and Piloting of an Online Education Program About Magnetic Resonance Imaging for People With Multiple Sclerosis.

Background: People with multiple sclerosis (pwMS) lack sufficient magnetic resonance imaging (MRI) knowledge to truly participate in frequently occurring MRI-related therapy decisions. An evidence-based patient information (EBPI) about MRI is currently lacking. Objective: The aim of this study was to develop an evidence-based online education program about limitations and benefits of MRI for pwMS. Ultimately, our goal was to improve MRI risk-knowledge, empower pwMS, and promote shared decision-making. Methods: The program's contents were based on literature research and a previous pilot study. It was revised following 2 evaluation rounds with pwMS, MRI experts and expert patients. In a pilot study, n = 92 pwMS received access to the program for 4 weeks. User experiences and acceptance, MRI knowledge (MRI-RIKNO 2.0 questionnaire) and emotions and attitudes toward MRI (MRI-EMA questionnaire) were assessed. Results were compared to a previous survey population of n = 508 pwMS without access to the program. Results: Participants rated the program as easy to understand, interesting, relevant, recommendable, and encouraging. In comparison to pwMS without access to the program, MRI risk-knowledge and perceived MRI competence were higher. Conclusion: Satisfaction with the program and good MRI-risk knowledge after usage demonstrates the need and applicability of EBPI about MRI in MS.

Development and evaluation of a website with patients experiences of multiple sclerosis: a mixed methods study.

BACKGROUND: A variety of management options (e.g., disease-modifying therapy, lifestyle interventions, rehabilitation) are available for persons with relapsing-remitting multiple sclerosis (MS). Besides coping with the diagnosis, persons with MS have to make complex decisions, e.g., regarding disease-modifying therapies. In addition to factual information, reports of patient experiences may support other patients in their decision-making. Therefore, we developed a website presenting patient experiences illustrated by video, audio and text files. This study aimed to test the acceptability and usability of a website with patient experiences with MS. METHODS: A mixed-methods approach was applied. A total of 69 participants visited the German "Patient Experiences with MS (PExMS)" website and among them, 50 persons with MS and 6 experts completed an online survey. In total, 18 participants took part in telephone interviews or focus groups. Data from the survey were analysed using descriptive statistics. Qualitative data were analysed using thematic analysis. RESULTS: Both quantitative and qualitative responses suggest that the PExMS website was viewed positively by patients and experts. 94% of persons with MS agreed that the information was comprehensible and reliable. 54% felt encouraged to share their health problems with others after having studied the website. 74% claimed to use the website if they had to make a decision regarding their health. Qualitative responses deduced from the website fell into 5 key themes: (1) web design, appearance, and functionality, (2) content, (3) usability, (4) satisfaction, and (5) loyalty. The search for persons of similar age and with comparable experiences was a major driving force to navigate the website. The material on the website was perceived as diverse, covering both positive and negative experiences in daily living with MS. All participants greatly appreciated having access to other people's experiences online and judged the material on the website as particularly helpful in decision-making for disease-modifying therapies. CONCLUSIONS: The findings suggest that the PExMS website might have the potential to be a useful source of audio-visual information for persons with MS. Given the lack of websites available to patients with experiential information, health care professionals may be encouraged to routinely inform patients about this website at regular appointments.

Patients experiences with multiple sclerosis disease-modifying therapies in daily life - a qualitative interview study.

BACKGROUND: Besides coping with a disease with many uncertainties, people with relapsing-remitting multiple sclerosis face complex decisions concerning disease-modifying therapies (DMTs). In an interview study, we aimed to assess patients' experiences with DMTs. METHODS: Problem-centred interviews were conducted with 50 people with relapsing-remitting multiple sclerosis in Germany using maximum variation sampling and covering all licensed DMTs. Data were analysed thematically using deductive and inductive categories. RESULTS: 47 of 50 patients had treatment with at least one of the approved DMTs. The main themes were: (1) starting a DMT, (2) switching to another DMT, (3) discontinuing a DMT, and (4) multiple sclerosis without starting a DMT. Different intercorrelated factors influenced the decision-making processes for or against a DMT. Individual experiences with DMTs in daily life contained the effort in administration, success, and failure of DMTs, coping strategies and well-being without DMTs. The decision-making process for or against a DMT and the use of those treatments can be understood as a constant, continually shifting process, complicated by different factors, which change over time. Experiences with DMTs were characterized by attempts to handle uncertainty and to (re)gain control and integrate adaptivity into one's life. CONCLUSIONS: The study provides a rich and nuanced amount of patients' experiences with DMTs. The findings demonstrate the importance for practitioners to look at current life circumstances of patients with multiple sclerosis when recommending a DMT and to promote and enable patients to make informed decisions.

Evaluation of an interactive web-based programme on relapse management for people with multiple sclerosis (POWER@MS2): study protocol for a process evaluation accompanying a randomised controlled trial.

INTRODUCTION: Process evaluations accompanying complex interventions examine the implementation process of the underlying intervention, identify mechanisms of impact and assess contextual factors. This paper presents the protocol for a process evaluation conducted alongside the randomised controlled trial POWER@MS2. The trial comprises the evaluation of a web-based complex intervention on relapse management in 188 people with multiple sclerosis conducted in 20 centres. The web-based intervention programme focuses on relapse treatment decision making and includes a decision aid, a nurse-led webinar and an online chat. With the process evaluation presented here, we aim to assess participants' responses to and interactions with the intervention to understand how and why the intervention produces change. METHODS AND ANALYSIS: A mixed methods design is used to explore the acceptance of the intervention as well as its use and impact on participants. Participants are people with multiple sclerosis, neurologists, nurses and stakeholders. Quantitative semistandardised evaluation forms will be collected throughout the study. Qualitative semistructured telephone interviews will be conducted at the end of the study with selected participants, especially people with multiple sclerosis and neurologists. Quantitative data will be collected and analysed descriptively. Based on the results, the qualitative interviews will be conducted and analysed thematically, and the results will be merged in a joint display table. ETHICS AND DISSEMINATION: The process evaluation has received ethical approval from the Ethical Committee of the University of Lübeck (reference 19-024). Findings will be disseminated in peer-reviewed journals, at conferences, meetings and on relevant patient websites. TRIAL REGISTRATION NUMBER: NCT04233970.

Development and evaluation of an interactive web-based decision-making programme on relapse management for people with multiple sclerosis (POWER@MS2)-study protocol for a randomised controlled trial.

INTRODUCTION: Multiple sclerosis is a chronic inflammatory, degenerative disease of the central nervous system manifesting at first with relapses in about 85% of cases. In Germany, intravenous therapy with high-dose corticosteroids is the treatment standard of acute relapses. The treatment leads to a faster reduction of symptoms in about 25 of 100 treated patients but has no proven long-term benefits over placebo treatment. Intravenous treatment is not superior to oral treatment. Therefore, informed decisions on relapse management are required. An earlier randomised controlled trial showed that evidence-based patient information and education on relapse management leads to more informed decisions and more relapses not treated or treated with oral corticosteroids. This study aims to evaluate whether a web-based relapse management programme will positively change relapse management and strengthen autonomy in people with multiple sclerosis. METHODS: The pragmatic double-blind randomised controlled trial is accompanied by a mixed-methods process evaluation and a health economic evaluation and follows the UK Medical Research Council guidance on developing and evaluating complex interventions. A total of 188 people with possible or relapsing-remitting multiple sclerosis with ≥ 1 relapse within the last year and/or ≥ 2 relapses within the last 2 years will be recruited and randomised using blocks. The intervention group receives a web- and dialogue-based decision aid on relapse management, a nurse-led webinar and access to a monitored chat forum. The control group receives standard information, which will be made available via the same online platform as the intervention. The primary endpoint is the proportion of relapses not treated or treated with oral corticosteroids. Key secondary endpoints are the annualised relapse rate, decision-making, empowerment, quality of life and cost-effectiveness. Facilitators and barriers will be assessed by mixed-methods process evaluation measures. The study ends when 81 relapses have been documented or after 24 months of observation per individual patient. Analyses will follow the intention-to-treat principle. DISCUSSION: We hypothesise that the intervention will enhance patient empowerment and have a positive impact on patients' relapse management. TRIAL REGISTRATION: ClinicalTrials.gov NCT04233970 . Registered on 18 January 2020.

Impact of a multimedia website with patient experiences of multiple sclerosis (PExMS) on immunotherapy decision-making: study protocol for a pilot randomised controlled trial in a mixed-methods design.

BACKGROUND: A variety of management options (e.g. immunotherapies, lifestyle interventions, and rehabilitation) are available for people with relapsing-remitting multiple sclerosis (RRMS). Besides coping with the diagnosis, people with MS (pwMS) have to make complex decisions such as deciding about immunotherapies. In addition to factual information, reports of patient experiences (PEx) may support patients in decision-making. The added value of PEx in decision-making is not clear, and controlled studies are rare. Therefore, systematic methods are necessary to develop and analyse PEx. As there are no evaluated PEx for MS in Germany, we are currently creating a website presenting PEx structured according to topics and illustrated by video, audio, and text files. We aim to determine the feasibility of an intervention using PEx and evaluate whether PEx may help pwMS in their immunotherapy decision-making processes as a supplement to evidence-based information. METHODS: This project will follow the Medical Research Council framework for development and evaluation of complex interventions. After the development of a website with PEx, a randomised controlled pilot trial (pilot RCT) will be conducted in 2-3 MS centres, clinics, or rehabilitation centres including 55 pwMS and accompanied by a process evaluation. Patients with a RRMS diagnosis considering immunotherapy are eligible. The primary outcome is decision self-efficacy. Secondary outcomes include preparation for decision-making, decisional conflict, risk knowledge, confidence in active participation, affective forecasting, social support, and self-reported impact of eHealth on its users. Participants will be randomly assigned either to (i) an intervention group with 4 weeks access to an evidence-based patient information resource and the PExMS-website as an adjunct or to (ii) the control group with access to evidence-based information alone. A 6-member advisory panel involving representatives of pwMS, researchers, and neurologists, who accompany the whole project, will mentor this pilot RCT. DISCUSSION: The intervention was developed with systematic methods, created with active patient involvement and in critical appraisal by an expert advisory panel. The study is innovative as it contributes to the controversial evidence on the use of PEx in the context of evidence-based patient information. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04236544.

Long-term prognostic counselling in people with multiple sclerosis using an online analytical processing tool.

BACKGROUND: Prognostic counselling is a sensitive issue in medicine and especially so in MS due to the highly heterogeneous disease course. However, people with MS (pwMS) seek prognostic information. The web-based 'Evidence-Based Decision Support Tool in Multiple Sclerosis' (EBDiMS) uses data of 717 patients from the London/Ontario cohort to calculate personalized long-term prognostic information. OBJECTIVE: The aim of this study was to investigate the feasibility and effect of long-term prognostic counselling in pwMS using EBDiMS. METHODS: Ninety consecutive pwMS were provided with personalized estimations of expected time to reach Expanded Disability Status Scale (EDSS) scores of 6 and 8 and time to conversion to secondary-progressive MS. Participants gave estimates on their own putative prognosis and rated the tool's acceptability on six-step Likert-type scales. RESULTS: Participants rated EBDiMS as highly understandable, interesting and relevant for patient-physician encounters, coping and therapy decisions. Although it provoked a certain degree of worry in some participants, 95% would recommend using the tool. Participants' own prognosis estimates did not change significantly following EBDiMS. CONCLUSION: Long-term prognostic counselling using an online tool has been shown to be feasible in a clinical setting. EBDiMS provides pwMS with relevant, easy-to-understand, long-term prognostic information without causing relevant anxiety.

Emotions towards magnetic resonance imaging in people with multiple sclerosis.

OBJECTIVES: People with multiple sclerosis (pwMS) often have magnetic resonance imaging (MRI) examinations. While MRI can help guide MS management, it may be a source of anxiety for pwMS. We aimed to develop and validate a questionnaire on the "EMotions and Attitudes towards MRI" (MRI-EMA). MATERIAL AND METHODS: The questionnaire was developed, tested in two samples of pwMS and validated in a sample of n = 457 pwMS using exploratory (EFA) and confirmatory factor analysis (CFA). RESULTS: EFA revealed four factors underlying the questionnaire: fear of MRI scan, fear of MRI results, feeling of control over the disease and feeling of competence in the patient-physician encounter. CFA confirmed the model fit. Receiving the MRI results, but not undergoing the procedure was associated with anxiety. Seeing MRI results gave participants a feeling of control over the disease. Only 50% felt competent to discuss MRI findings with their physician. Fear of MRI results was especially high and feeling of competence low in participants with a short disease duration and little MRI experience. CONCLUSION: PwMS do not feel competent when discussing the role, MRI plays in their care. Receiving MRI results caused anxiety and provides some pwMS with a-perhaps false-feeling of control over the disease. The MRI-EMA constitutes a new tool for the assessments of pwMS' feelings towards MRI, that can be applied in future research and clinical settings.

Retrospective evaluation of patients with uveal melanoma treated by stereotactic radiosurgery with and without tumor resection.

IMPORTANCE: The present study intended to analyze the suitability of single-dose stereotactic radiotherapy in the treatment of uveal melanoma that cannot be handled with ruthenium-brachytherapy and therefore is a challenge for ophthalmologists concerning local tumor control, as well as preservation of the eye and visual function. OBJECTIVES: To evaluate local tumor control, eye preservation, visual course, radiation complications, metastases, and death after single-dose stereotactic radiotherapy (SDRT) applied exclusively or combined with tumor resection in uveal melanomas that are neither suitable nor favorably located for ruthenium brachytherapy. DESIGN: Retrospective, observational case series. SETTING: Primary care center. PARTICIPANTS: Seventy-eight patients with uveal melanoma were treated. INTERVENTION: Between June 3, 2003, and March 18, 2008, patients with uveal melanoma received SDRT monotherapy (group 1, 60 patients) or SDRT combined with tumor resection (group 2, 18 patients). Radiotherapy was performed with a tumor-surrounding dose of 25 Gy on a linear accelerator. MAIN OUTCOME MEASURES: Local tumor control, eye preservation, visual results, and radiation complications. RESULTS: Within a median follow-up of 33.7 months (range, 0.13-81.13 months), 6 recurrences occurred in group 1; none recurred in group 2. The Kaplan-Meier estimate for local control was 85% at 3 years in group 1 and 100% in group 2 (P = .22). Eye preservation rate was 77% vs 87% at 3 years (groups 1 and 2, respectively) (P = .82). Visual acuity decreased with a median loss of -18 Snellen lines (group 1) and -22 Snellen lines (group 2). More retinopathies (P = .07), opticopathies (P = .27), and rubeotic glaucomas (P = .10) occurred in group 1. No significant difference was observed in the development of metastases (P = .33). The groups differed in overall survival because of 2 deaths occurring shortly after surgery in group 2 for unexplained reasons (P = .06). CONCLUSIONS AND RELEVANCE: Survival analysis suggested that SDRT with combined tumor resection might be associated with increased tumor control and fewer radiation complications than SDRT as monotherapy. Both groups had similar eye retention rates and were comparable concerning the decrease in visual function in most eyes. However, the protocol was stopped after 3 unexplainable deaths after surgery.

Low dose non-enhanced CT versus standard dose contrast-enhanced CT in combined PET/CT protocols for staging and therapy planning in non-small cell lung cancer.

PURPOSE: To evaluate low dose non-enhanced CT and standard dose contrast-enhanced CT in combined PET/CT protocols for staging and therapy planning of non-small cell lung cancer (NSCLC). METHODS: Retrospective analysis was performed of 50 consecutive patients with proven NSCLC who had been referred for primary staging (n=41) or restaging (n=9). All patients underwent a multi-phase PET/CT consisting of a low dose non-enhanced attenuation scan and an arterial and portal-venous contrast-enhanced CT scan followed by whole-body PET. Fused datasets of non-enhanced and contrast-enhanced PET/CT were compared per patient by using the TNM staging system, and per lesion regarding localisation, characterisation and delineation of tumour lesions. The staging results were validated either by histopathology or by clinical-radiological follow-up for >or=6 months. RESULTS: In 47/50 patients, the results of T staging did not differ between the two PET/CT protocols. Three patients could only be correctly classified as having T4 tumours after contrast application. Regarding N staging, both protocols yielded the same results. In M staging, there was only one patient with an improvement of the results as a result of contrast application. The lesion-based analysis of 92 sites showed no difference in the accuracy of lesion localisation and only one revision of lesion characterisation by contrast-enhanced PET/CT. The assessment of tumour delineation was altered by contrast application in 58/92 sites (p<0.0001). In 10/50 patients, contrast-enhanced PET/CT detected additional clinically important findings. CONCLUSION: In patients with advanced NSCLC, contrast-enhanced CT as part of the PET/CT protocol more accurately assessed the TNM stage in 8% of patients compared with non-contrast PET/CT. However, for planning of 3D conformal radiotherapy and non-conventional surgery, contrast-enhanced PET/CT protocols are indispensable owing to their superiority in precisely defining the tumour extent.

First experiences of radiation treatment planning with PET/CT.

BACKGROUND: Positron emission tomography/computed tomography (PET/CT) is composed of modern CT and PET technology in one machine enabling examinations of patients in one session in the same position. Its value for modern radiation treatment planning is under investigation. METHODS: In 53 patients with head-and-neck (n = 11), non-small cell lung (n = 16), prostate (n = 14) and other cancers (n = 12), a PET/CT investigation was performed. During the diagnostic examination process an integrated scan under radiation treatment-planning conditions was included. Interpretation and delineation of macroscopic tumor were done in an interdisciplinary approach. Treatment changes occurred after critical interpretation of the PET/CT findings by the responsible radiotherapist. Analysis is descriptive with regard to changes in treatment intention, mode, radiation volumes and doses. RESULTS: Examinations were well tolerated. CT datasets in treatment position could be used for planning. Delineation of macroscopic tumor led to changes of the planning target volume after PET/CT 15 times, total dose was modified twelve times. PET/CT examinations led to changes of the general treatment mode in 19 cases. Using the separate CT and PET datasets, fusion in the planning software was easily performed in all patients due to the use of the same positioning and immobilization devices in PET/CT. CONCLUSION: Despite the low number of patients and an expected bias of selection, the first results are encouraging to perform more extended and detailed trials of this technology in radiotherapy planning. Whether PET/CT is superior to PET alone is part of ongoing investigations.

Kinetic analysis of dynamic 18F-fluoromisonidazole PET correlates with radiation treatment outcome in head-and-neck cancer.

BACKGROUND: Hypoxia compromises local control in patients with head-and-neck cancer (HNC). In order to determine the value of [18F]-fluoromisonidazole (Fmiso) with regard to tumor hypoxia, a patient study with dynamic Fmiso PET was performed. For a better understanding of tracer uptake and distribution, a kinetic model was developed to analyze dynamic Fmiso PET data. METHODS: For 15 HNC patients, dynamic Fmiso PET examinations were performed prior to radiotherapy (RT) treatment. The data was analyzed using a two compartment model, which allows the determination of characteristic hypoxia and perfusion values. For different parameters, such as patient age, tumor size and standardized uptake value, the correlation to treatment outcome was tested using the Wilcoxon-Mann-Whitney U-test. Statistical tests were also performed for hypoxia and perfusion parameters determined by the kinetic model and for two different metrics based on these parameters. RESULTS: The kinetic Fmiso analysis extracts local hypoxia and perfusion characteristics of a tumor tissue. These parameters are independent quantities. In this study, different types of characteristic hypoxia-perfusion patterns in tumors could be identified. The clinical verification of the results, obtained on the basis of the kinetic analysis, showed a high correlation of hypoxia-perfusion patterns and RT treatment outcome (p = 0.001) for this initial patient group. CONCLUSION: The presented study established, that Fmiso PET scans may benefit from dynamic acquisition and analysis by a kinetic model. The pattern of distribution of perfusion and hypoxia in the tissue is correlated to local control in HNC.
