Comparative study of PROMISⓇ self-efficacy for managing chronic conditions across chronic neurologic disorders

Thrombolysis treatment protected impairment of functional ability, quality of life and fatigue seven years after stroke

OBJECTIVES

We studied quality of life, functional outcome, depression, and fatigue of ischemic stroke patients treated with or without thrombolysis seven years post-stroke.

MATERIALS AND METHODS

A total of 204 ischemic stroke patients treated with or without thrombolysis during 2013-2015. After seven years the 136 survivors were assessed with telephone interview, which included questions about subjective quality of life (European Quality of Life-5 Dimensions), depression, fatigue with Fatigue Severity Scale, functional ability assessed with Barthel Index and Modified Rankin Scale, living conditions, need of care, and medical aids.

RESULTS

At admission patients with thrombolysis had higher National Institutes of Health Stroke Scale scores compared with those not treated with thrombolysis. At seven years post-stroke, 99% of alive patients answered the questionnaires. There were no group differences concerning functional outcome, quality of life, depression, fatigue, or insomnia. The Barthel Index was normal in both groups. The quality of life was good in both groups without group differences in any domains. Of all patients, 68% reported no problems in usual activities, and 61% were without pain. Anxiety or depression were experienced by 19% of all stroke patients, while fatigue was present in 32% of cases.

CONCLUSIONS

Seven years post-stroke the quality of life was good and functional outcome remained in good level in both study groups. One third experienced fatigue, while every fifth experienced depression. The thrombolysis treatment seems to protect from decreased quality of life, fatigue, and decreased mobility, self-care, and usual activities despite more severe stroke.

Fatigue, Toll-Like Receptor 4, and Pro-Inflammatory Cytokines in Adults With Subarachnoid Hemorrhage: A 6-Month Longitudinal Study

BACKGROUND

Fatigue is prevalent in subarachnoid hemorrhage (SAH) survivors. Biological mechanisms underlying fatigue post-SAH are not clear. Inflammation may contribute to the development of fatigue. This study aimed to examine the associations between inflammatory markers and fatigue during the first 6 months post-SAH. Specific biomarkers examined included both early and concurrent expression of Toll-Like Receptor 4 (TLR4) messenger RNA (mRNA) and plasma concentrations of pro-inflammatory cytokines, Tumor Necrosis Factor-alpha (TNF-α), Interleukin (IL)1β, and IL6.

METHODS

We conducted a 6-month longitudinal study with a convenience sample of 43 SAH survivors. We collected blood samples on days 2, 3, and 7 and 2, 3, and 6 months post-SAH to assess biomarkers. Fatigue was assessed by the PROMIS Fatigue Scale at 2, 3, and 6 months. Linear mixed models were used to test the associations between early (days 2, 3, and 7) and concurrent (2, 3, and 6 months) TLR4 mRNA expression (TagMan gene expression assays) and TNF-α, IL1β, and IL6 plasma concentrations (multiplex assays) and concurrent fatigue.

RESULTS

28% of SAH survivors experienced fatigue during the first 6 months post-SAH. Fatigue levels in SAH survivors were higher than those of the U.S. population and consistent during the 6 months. Experience of fatigue during the 6 months post-SAH was associated with higher IL1β plasma concentrations on day 7 and IL1β, IL6, and TNF-α plasma concentrations during the 6 months post-SAH.

CONCLUSION

Inflammation appears to underlie the development of fatigue in SAH survivors.

Psychosocial interventions affecting global perceptions of control in people with Parkinson's disease: a scoping review

PURPOSE

Perceived control is an important construct for the psychological well-being of people affected by chronic conditions, and higher perceived control is associated with better outcomes. Psychosocial interventions have been trialled in these populations to improve both global and specific perceptions of control. However, most interventions involving people with Parkinson's have focused on single-domain forms of control, while those addressing global perceived control are yet to be reviewed. This study aimed to identify and map the types of psychosocial interventions in individuals with Parkinson's which have included forms of global perceived control as an outcome.

MATERIALS AND METHODS

Scoping review based on a search across MEDLINE, PsycINFO, CINAHL, Academic Search Ultimate.

RESULTS

From an initial return of 4388 citations, 12 citations were eventually included. These consisted of 8 quantitative and 4 qualitative studies, and covered 4 overarching categories of psychosocial interventions. Mixed results were found for cognitive, educational, and physical interventions, while a randomised controlled trial on mindfulness-based lifestyle programme showed more preliminary positive evidence.

CONCLUSIONS

Further rigorous research is required on the topic to build on these preliminary findings. In the meantime, clinicians may need to consider programmes which proved effective with populations similar to people with Parkinson's.IMPLICATIONS FOR REHABILITATIONPerceived control is a psychological construct important for people with chronic illnesses, which can be targeted by psychosocial interventions.This article reviewed psychosocial interventions targeting global forms of perceived control in Parkinson's.Mixed results were reported for the cognitive, educational, and physical interventions identified, while a randomised controlled trial on a mindfulness-based lifestyle programme showed more promising evidence.In the meantime, clinicians may need to consider programmes found to be effective with people with similar conditions to Parkinson's.

Cognitive Self-Efficacy in Parkinson's Disease

Cognitive self-efficacy (CSE), one's belief in their ability to control their cognitive performance, is important for participation in daily activities and rehabilitation. This study aims to understand how Parkinson's disease (PD) affects CSE. The Cognitive Self-Efficacy Questionnaire (CSEQ) was administered to 47 non-demented PD and 52 healthy comparison (HC) participants. Groups were compared on their self-reported ability to recognize (Part 1) and manage (Part 2) cognitive symptoms and to perform cognitively complex functional activities (Part 4). Relationships between CSEQ scores and individual characteristics were assessed within PD. The PD group had lower CSEQ scores than the HC group for all Parts. Within PD, Part 2 scores were lower than Parts 1 and 4, and worse depressive symptoms and higher medication dosage correlated with lower CSE. People with PD may have low CSE, which can contribute to participation restrictions and reduced engagement in treatment. Occupational therapists should consider CSE with clients with PD.

Global health measures from a National Down Syndrome Registry

People with Down syndrome (DS) have a unique medical profile which may impact views of health. We aimed to study the use of global health measures for DS in a national cohort. We prospectively surveyed parents of individuals with DS from the DS-Connect® registry with validated Patient Reported Outcomes Measurement Information System (PROMIS)® instruments of global health. Analyses included use of scoring manuals and the PROMIS® scoring service, descriptive statistics, and t-tests. We received completed surveys from 223 parents of individuals with DS; previously published limitations of the instrument in this population were shown again. T-scores differed from the available comparative standardized scores to these measures from PROMIS® reference population on Fatigue (p < 0.001) and Global Health (p < 0.001), but not on Pain Interference (p = 0.41).

Feasibility and Efficacy of Online Neuropsychological Assessment

Neuropsychological testing has intrinsic challenges, including the recruitment of patients and their participation in research projects. To create a method capable of collecting multiple datapoints (across domains and participants) while imposing low demands on the patients, we have developed PONT (Protocol for Online Neuropsychological Testing). Using this platform, we recruited neurotypical controls, individuals with Parkinson's disease, and individuals with cerebellar ataxia and tested their cognitive status, motor symptoms, emotional well-being, social support, and personality traits. For each domain, we compared each group to previously published values from studies using more traditional methods. The results show that online testing using PONT is feasible, efficient, and produces results that are in line with results obtained from in-person testing. As such, we envision PONT as a promising bridge to more comprehensive, generalizable, and valid neuropsychological testing.

Self-management education for children with epilepsy and their caregivers. A scoping review

Self-management education programs have been highly successful in preparing people to manage medical conditions with recurring events. A detailed curriculum for epilepsy patients, and their caretakers, is lacking. Here we assess what is available for patients who have disorders with recurring events and offer an approach to developing a potential self-care curriculum for patients with seizures and their caregivers. Among the anticipated components are a baseline efficacy assessment and training tailored to increasing self-efficacy, medication compliance, and stress management. Those at risk of status epilepticus will also need guidance in preparing a personalized seizure action plan and training in how to decide when rescue medication is appropriate and how to administer the therapy. Peers, as well as professionals, could teach and provide support. To our knowledge, no such programs are currently available in English. We encourage their creation, dissemination, and widespread use.

A better self-efficacy is predictive of better health-related quality of life (HRQoL) in patients with systemic lupus erythematosus: data from the Almenara Lupus Cohort

OBJECTIVE

To determine the possible predictive value of self-efficacy on health-related quality of life (HRQoL) in patients with SLE.

METHODS

Patients with SLE from the Almenara Lupus Cohort were included. Self-efficacy was ascertained with the six domains from the Patient-Reported Outcomes Measurement Information System (PROMIS) self-efficacy for managing chronic conditions. For PROMIS domains, a score of 50 is the average for a clinical population (people with a chronic condition), a higher score indicates that the respondent has greater self-efficacy. HRQoL was ascertained with the physical and mental component summary (PCS and MCS) measures of the Short-Form 36 (SF-36). Generalised estimating equations were performed, using as outcome the PCS or MCS in the subsequent visit, and the self-efficacy domain in the previous visit; multivariable models were adjusted for possible confounders. The confounders were measured in the same visit as the self-efficacy domain.

RESULTS

Two-hundred and nine patients for a total of 564 visits were included; 194 (92.8%) patients were women and mean age at diagnosis was 36.4 (14.0) years. In the multivariable models, a better PCS was predicted by a better self-efficacy for managing symptoms, managing medications and treatments and managing social interactions and general self-efficacy; a better MCS was predicted by a better self-efficacy for managing daily activities, managing symptoms, managing medications and treatments and managing social interactions.

CONCLUSION

A better self-efficacy is predictive of subsequent better HRQoL, even after adjustment for possible confounders. These results should encourage clinicians to develop strategies to improve self-efficacy in patients with SLE.

Somatoform Symptoms in Parkinson Disease

BACKGROUND

Co-occurring somatoform symptoms complicate the diagnosis and treatment of Parkinson disease (PD).

OBJECTIVE

To learn more about the relationship between somatoform symptoms and PD by comparing demographic and clinical features across PD groups differing in somatoform symptom severity.

METHOD

Using standardized Brief Symptom Inventory-18 (BSI-18) scores to measure somatoform symptom severity, we assigned 1093 individuals with PD to one of four subgroups using comparisons to normative means: low (M < -½ SD), average (M ± ½ SD), high (M +½ SD to +1 SD), very high (M > +1 SD). We used demographics and disease severity measures to assess each subgroup.

RESULTS

Most of the individuals with PD (56%) had high or very high somatoform symptom levels. Increased somatoform symptom levels were associated with female gender, lower socioeconomic status, greater disease duration, increased PD severity (Total Unified Parkinson's Disease Rating Scale), greater disability (Older Americans Resource and Services Disability subscale), increased BSI-18 Depression and Anxiety subscale scores, lower cognitive function (Mini-Mental State Examination), lower self-efficacy scores (Self-Efficacy to Manage Chronic Disease Scale), lower quality of life scores (SF-12 Health Status Survey), and greater medical comorbidity (Cumulative Illness Rating Scale-Geriatrics) (all comparisons: P < 0.001). We found no significant between-group differences for age, race, or marital status.

CONCLUSION

Somatoform symptom severity in individuals with PD is associated with greater PD severity and disability and is more common in females and in individuals with low socioeconomic status. Greater awareness of somatoform symptoms should help improve PD treatment.

Peer Support Groups: Identifying Disparities to Improve Participation

Disparities in psychosocial outcomes after burn injury exist in patients from racial or ethnic minority groups in the United States. Peer support groups can help patients with many psychosocial aspects of recovery from burns; however, access to such support among patients of racial and ethnic minority or low socioeconomic groups are unknown. The present study examined participation rates in outpatient peer support within this patient population. Patients attending outpatient clinic at an urban safety-net hospital and regional burn center with a majority minority patient population were asked about participation in burn survivor group, interest in joining a group, and given validated survey questions about managing emotions and social interactions since injury. Current or past participation in peer support was low (4.2%), and 30.3% of patients not already in support group were interested in joining. Interest in future participation in peer support was highest among Hispanic patients (37.0%) and lowest among Black patients (0%). Logistic regression models demonstrated that increased total body surface area burned, hospital length of stay, and need for surgical intervention were associated with interest in joining or having joined a peer support group. Effectiveness of management of emotions and social interactions were not associated with interest in joining peer support in the future. These findings demonstrate a considerable difference between levels of interest and participation in peer support within this population. Improving access to and education about benefits of peer support in underresourced communities may help to address the variation in psychosocial outcomes of patients across racial or ethnic minority groups recovering from burns.

The use of PROMIS measures in clinical research in stroke patients, a systematic literature review

Objective

To systematically describe the use and outcomes of Patient-Reported Outcomes Measurement Information System (PROMIS) measures in clinical studies in populations with stroke.

Data Sources

A systematic search on the use of PROMIS measures in clinical stroke studies in 9 electronic databases.

Study Selection

Studies had to be original, reporting on outcome data using PROMIS measures in populations with stroke (ischemic and/or hemorrhagic), from January 1st, 2007. Initially, 174 unique studies met the inclusion criteria. In 2 steps, titles, abstracts and full-text articles were screened for eligibility (2 authors independently).

Data Extraction

From the selected articles, study characteristics, type of PROMIS measures, and its outcomes were extracted by 2 authors independently. The authors discussed their views to achieve consensus. A third author was consulted if necessary.

Data Synthesis

In total, 27 studies (24,366 patients) were included, predominantly from the United States (22); most study populations were hospital-based (20); the number of patients ranged from 30-3283. In general, patients had no or mild symptoms (median modified Rankin scale 1). Two different generic PROMIS measures were reported (PROMIS Global Health, PROMIS 29) and 9 PROMIS measures focusing on specific domains (sleep, pain, physical functioning, self-efficacy, satisfaction with social roles, depression, anxiety, cognition, fatigue). These match the International Classification of Functioning, Disability, and Health (ICF) domains mentioned in the Core Set for Stroke. The measures were administered 1-55 months after stroke. Outcome data are provided. Pooling of data was not achieved because of a large variety in study characteristics (inclusion criteria, follow-up moments, data processing).

Conclusions

The PROMIS measures in this review could be relevant from a patient's perspective, covering ICF core set domains for patients with stroke. The large variety in study characteristics hampers comparisons across populations. Many different outcome measures are used to report results of stroke rehabilitation studies.

Evaluation of a self-management intervention for adults with epilepsy in Taiwan: A longitudinal randomized controlled trial

PURPOSE

Epilepsy is a neurological disease that causes recurrent seizures and can have a significant impact on a person's quality of life (QOL). A self-management intervention (SMI) can allow adults with epilepsy to modify behaviors in order to manage their seizures and evaluate the impact of medication and treatments on their daily lives. The purpose of this study was to investigate the effects of a SMI for adults with epilepsy.

METHODS

This was a longitudinal randomized controlled trial. Adults with epilepsy between the age of 20 and 65 years were recruited from a medical center in northern Taiwan. Participants were assigned to an intervention group (IG) or control group (CG) through simple randomization. Data regarding demographic and clinical characteristics were collected at baseline (T0). In addition, participants answered nine validated self-report questionnaires, which were used as outcome measures. Following collection of baseline data, the CG received routine monthly counseling over the next 3 months. The IG received the routine monthly counseling, as well as individual face-to-face health counseling on self-management 1 h/month and remote counseling via the phone or computer network at least twice per month. After the first month (T1) and at the end of the third (T2) and sixth months (T3) participants answered the nine questionnaires again. Differences in outcomes between the IGs and CGs were analyzed by comparing scores for the nine outcome variables at T0 with scores at T1, T2, and T3 with generalized estimating equations.

RESULTS

A total of 210 adults agreed to participate in the study; however, only 155 participants completed the questionnaires for all three time points: 75 in the CG and 80 in the IG. The mean age of the 155 participants was 39.6 years (SD = 10.9). There was no significant difference between demographic or clinical variables between the two groups. The only difference in baseline scores (T0) among the nine self-report questionnaires was in epilepsy knowledge, measured with the Epilepsy Knowledge Profile questionnaire, which were significantly higher for the CG (mean = 32.28, SD = 3.92) than the IG (mean = 23.01, SD = 2.79) (p < 0.001). Generalized estimating equations (GEE) analysis showed scores decreased significantly at T3 from baseline for the CG for epilepsy knowledge and QOL (p < 0.001). Improvements in scores for sleep quality, anxiety, depression, self-efficacy, coping, and social support did not differ between groups. Classification of the IG by gender showed a significantly greater increase for males compared with females from baseline to T3 for epilepsy knowledge (p < 0.001). If we further classified the IGs by seizure frequency, participants with a seizure frequency of ≥1 per year had a more significant increase in epilepsy knowledge and increase in QOL compared with participants with a seizure frequency of <1 per year at T3 compared with T0.

CONCLUSION

The lack of improvement in health-related quality of life (HRQoL) following the SMI may indicate that additional time is required to change behaviors that impact this variable for patients with epilepsy. Additional research should focus on variables associated with medication compliance, epilepsy knowledge, medicine symptom distress, self-efficacy, anxiety, and HRQoL.

Piloting the use of global health measures in a Down syndrome clinic

PURPOSE

People with Down syndrome (DS) have a unique medical profile which may impact views of health. We aimed to explore the use of global health measures in DS.

METHODS

Prospective survey in the Mass General Hospital Down Syndrome Program (MGH DSP) from December 2018 to July 2019 with Patient Reported Outcomes Measurement Information System (PROMIS)® instruments of global health. Analyses included use of scoring manuals, descriptive statistics and dependent samples t test.

RESULTS

Seventeen adolescents, 48 adults with DS and 88 caregivers returned surveys; 137 were complete. Incomplete responses and notes showed limitations of the instruments in this population. Global health T-scores did not differ from the available comparative standardized scores to these measures from PROMIS® reference population (p > 0.05).

CONCLUSIONS

In the MGH DSP, pilot global health instruments were completed by some adults with DS and caregivers, with some limitations and scores similar to the PROMIS® reference population.

Synergy of pandemics-social isolation is associated with worsened Parkinson severity and quality of life

Social isolation and its deleterious effects on health increases with age in the general population. People with Parkinson’s Disease (PWP) are no exception. Social isolation is a risk factor for worsened health outcomes and increased mortality. Symptoms such as depression and sleep dysfunction are adversely affected by loneliness. There is a paucity of research on social isolation in Parkinson’s disease (PD), which is all the more critical now in the setting of social distancing due to COVID-19. The goal of this study was to survey individuals with PD to evaluate whether social isolation is associated with PD symptom severity and quality of life. Only individuals reporting a diagnosis of idiopathic PD were included in this analysis. The primary outcome measures were the Patient-Reported Outcomes in PD (PRO-PD) and questions from PROMIS Global related to social health. PRO-PD scores increased as social performance and social satisfaction scores diminished. Individuals who reported being lonely experienced a 55% greater symptom severity than those who were not lonely (P < 0.01). Individuals who documented having a lot of friends had 21% fewer symptoms than those with few or no friends (P < 0.01). Social isolation was associated with greater patient-reported PD severity and lower quality of life, although it is unclear whether this is the cause and/or a consequence of the disease. In essence, the Parkinson pandemic and the pandemic of social isolation have been further compounded by the recent COVID-19 pandemic. The results emphasize the need to keep PWP socially connected and prevent loneliness in this time of social distancing. Proactive use of virtual modalities for support groups and social prescribing should be explored.

Feasibility of an integrated multidisciplinary geriatric rehabilitation programme for older stroke patients: a process evaluation

Background

Almost half of the stroke patients admitted to geriatric rehabilitation has persisting problems after discharge. Currently, there is no evidence based geriatric rehabilitation programme available for older stroke patients, combining inpatient rehabilitation with adequate aftercare aimed at reducing the impact of persisting problems after discharge from a geriatric rehabilitation unit. Therefore, we developed an integrated multidisciplinary rehabilitation programme consisting of inpatient neurorehabilitation treatment using goal attainment scaling, home based self-management training, and group based stroke education for patients and informal caregivers. We performed a process evaluation to assess to what extent this programme was performed according to protocol. Furthermore, we assessed the participation of the patients in the programme, and the opinion of patients, informal caregivers and care professionals on the programme.

Methods

In this multimethod study, process data were collected by means of interviews, questionnaires, and registration forms among 97 older stroke patients, 89 informal caregivers, and 103 care professionals involved in the programme.

Results

A part of patients and informal caregivers did not receive all key elements of the programme. Almost all patients formulated rehabilitation goals, but among two thirds of the patients the goal attainment scaling method was used. Furthermore, the self-management training was considered rather complex and difficult to apply for frail elderly persons with stroke, and the percentage of therapy sessions performed in the patients’ home environment was lower than planned. In addition, about a quarter of the patients and informal caregivers attended the education sessions. However, a majority of patients, informal caregivers and care professionals indicated the beneficial aspects of the programme.

Conclusion

This study revealed that although the programme in general is perceived to be beneficial by patients, and informal and formal caregivers, the feasibility of the programme needs further attention. Because of persisting cognitive deficits and specific care needs in our frail and multimorbid target population, some widely used methods such as goal attainment scaling, and self-management training seemed not feasible in their current form. To optimize feasibility of the programme, it is recommended to tailor these elements more optimally to the population of frail older patients.

Goal-directed behavior in individuals with mild Parkinson's disease: Role of self-efficacy and self-regulation

Introduction

Deficits in goal-directed behavior are common in individuals with Parkinson's disease (PD) and have been ascribed to apathy. In addition to apathy, individuals' beliefs in their competence (self-efficacy) and capacity to regulate emotions, thoughts, and actions (self-regulation) are critical skills for goal-directed behavior. We investigated these skills and their relationship to motor and non-motor symptoms in individuals with PD. We also examined the neural correlates of these skills using functional magnetic resonance imaging (fMRI).

Methods

We enrolled 35 subjects with mild PD (Hoehn and Yahr stage ≤2.5) and used the new general self-efficacy (NGSES) and self-regulation scales (SRS). We correlated the scores on these scales with measures of cognition, anxiety, depression, apathy, fatigue, quality of life, and disease burden using stepwise regression analyses. We collected resting-state fMRI data in a 3-Tesla scanner and computed the pairwise functional connectivity among nodes of major networks. We correlated the connectivity maps with the NGSES and SRS scores.

Results

Our PD cohort demonstrated intact NGSES and SRS scores compared with respective population data. These scores showed significant negative correlation with apathy and disease burden. Stronger connectivity in the salience network and decoupling from the default mode network supported self-efficacy and self-regulation.

Conclusions

Self-efficacy and self-regulation capacity seems preserved, but vulnerable to disease-related factors in individuals with mild PD. Educational programs cultivating this capacity could improve the coping skills of these individuals. Functional connectivity changes in salience and default mode networks may serve as neurobiological markers to demonstrate the effectiveness of such interventions.

•

Self-efficacy and self-regulation skills are critical for goal-directed behavior.

•

These skills and their neural bases were tested in mild Parkinson's disease.

•

These skills are intact and correlate negatively with apathy and disease burden.

•

Functional connectivity among nodes of major neural networks supports these skills.

•

These skills can be cultivated in educational programs for better health outcomes.

Self-efficacy for managing hypertension and comorbid conditions

BACKGROUND

Self-efficacy is defined an individual’s belief in completing necessary actions to achieve the desired goal. For individuals with hypertension and other chronic conditions, self-efficacy has been an essential factor to predict adherence to treatment behaviors.

AIM

To examine self-efficacy for managing chronic conditions in individuals with hypertension.

METHODS

A total of 1087 individuals with chronic conditions in two groups (hypertension and non-hypertension groups) were selected in this study. The two groups’ self-efficacy for managing chronic conditions were investigated using the five domains of patient reported outcomes measurement information system self-efficacy for managing chronic conditions measures (PROMIS-SE); daily activities, emotions, medication and treatment, social interactions, and symptoms. Also, the relationships between self-efficacy and other health-related outcomes for the hypertension group were examined using structural equation modeling.

RESULTS

Among 1087 participants, 437 reported having hypertension. The hypertension and non-hypertension groups were statistically different in self-efficacy for managing daily activities [F (1, 598) = 5.63, P < 0.05]. Structural equation modeling indicated that for individuals with hypertension, two domains of PROMIS-SE (managing daily activities and emotions) significantly predict global physical health (P < 0.001 and P < 0.01 sequentially), and one domain (managing emotions) significantly predicts mental health (P < 0.001). Hypertension patients’ general quality of life was significantly predicted by global physical health (P < 0.001) and mental health (P < 0.001).

CONCLUSION

The hypertension group reported deficits in self-efficacy in managing daily activities as compared to the non-hypertension group. In this hypertension group, self-efficacy functioned as an indirect predictor of general quality of life, mediated by global physical and mental health.

A randomized pragmatic trial of telephone-delivered cognitive behavioral-therapy, modafinil, and combination therapy of both for fatigue in multiple sclerosis: The design of the "COMBO-MS" trial

BACKGROUND

Fatigue is one of the most common and disabling chronic symptoms in multiple sclerosis (MS). Optimization of available treatments for MS-related fatigue has been stymied by lack of comparative effectiveness research that focuses on real-world treatment delivery methods and potential modification of treatment effect by other chronic MS symptoms or disability level. This report describes the design of a patient centered, comparative effectiveness trial of cognitive behavioral-therapy (CBT), modafinil, and combination therapy of both for fatigue in MS ("COMBO-MS").

METHODS

We describe the methods of this pragmatic comparative effectiveness trial that is guided by a team of patient, family, provider, community, and payer stakeholders. Eligible participants with MS and significant fatigue severity are randomly assigned (1:1:1) to received either CBT, modafinil, or a combination of CBT and modafinil for 12 weeks. The primary outcome is change in fatigue impact as measured by the Modified Fatigue Impact Scale (MFIS) at 12 weeks. Secondary outcome measures include ecological momentary assessment (EMA) measures of fatigue intensity, fatigue interference, and fatigability (measured over 7 days' time at baseline and at 12 weeks), and change in MFIS score at 24 weeks.

PROJECTED OUTCOMES

We hypothesize that combination therapy will more effectively ameliorate fatigue severity than either monotherapy, and that heterogeneity of treatment effects will be found based on depression status, presence of known or suspected sleep disorder, and disease severity. Study findings will assist patients, providers, payers, and policy makers to provide more effective care for managing fatigue in MS.
