RESUMO

BACKGROUND: In stroke survivors, post-stroke fatigue predicts dependency in daily living and failure to return to work. Modafinil shows promise as a pharmacotherapy to reduce post-stroke fatigue and related sequelae, e.g., poorer functional and clinical outcomes. AIMS: This study explored the cost-effectiveness of modafinil in treating post-stroke fatigue in the Australian context, by determining its incremental cost-effectiveness ratio (ICER) and by simulating the potential cost-savings on a national scale, through a re-analysis of MIDAS trial data. METHODS: A post hoc cost-effectiveness analysis was undertaken. Part A: patient-level cost and health effect data (Multidimensional Fatigue Inventory (MFI) scores) were derived from the MIDAS trial and analysis undertaken from a health-system perspective. Part B: a secondary analysis simulated the societal impact of modafinil therapy in terms of national productivity costs. RESULTS: Part A: Mean cost of modafinil treatment was AUD$3.60/day/patient for a minimally clinically important change (10 points) in total MFI fatigue score, i.e., AUD$0.36/day/unit change in fatigue score per patient. For the base case scenario, the ICER of using modafinil (versus placebo) was AUD$131.73 ($90.17 - 248.15, for minimum and maximum costs, respectively). Part B: The potential productivity cost-savings to society were calculated as nearly AUD$467 million over 1 year, and up to $383,471,991,248 over 10 years, from the widespread use of modafinil treatment in the Australian population of working-age stroke-survivors, representing a significant societal benefit. CONCLUSIONS: Modafinil is a highly cost-effective treatment for post-stroke fatigue, offering significant productivity gains and potential cost-savings to society from the widespread use of modafinil treatment in the Australian population of working-age stroke-survivors.

RESUMO

Two studies investigated subjective conceptualizations of energy for goal pursuit across adulthood. Study 1 (N = 276, 20-92 years of age) explored age-related differences in the (a) endorsement of a limited versus nonlimited account of energy for goal pursuit, (b) amount of energy available for physically, mentally, socially, and emotionally demanding activities, and (c) extent to which spending energy on a demanding activity inhibits or facilitates energy expenditure for subsequent activities, both within and across functional domains. Study 2 (N = 147, 18-86 years of age) experimentally induced energy loss through a 20-min physical exercise and examined age-related differences in the increase of subjective exhaustion and opportunity costs as a motivational cue for goal disengagement. With increasing age, adults more strongly endorsed a nonlimited account of energy and perceived having more energy available for personally relevant social activities. However, older adults also reported higher negative cross-domain energy spillover after physical exertion. Multilevel growth curve models further revealed that, compared with younger adults, older adults reported a steeper initial increase in exhaustion and opportunity costs during physical exercise, but converged with the younger age groups again at the close of the exercise session. The discussion centers around the importance of selectivity in older adulthood and motivational accounts of effort and exhaustion. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

RESUMO

Aims: The aim of this study was to quantify how multiple sclerosis (MS) phenotypes differ from each other in respect of costs and quality-of-life.Materials and methods: The study is based on survey data from Finnish patients with MS (n = 553). The information contained disease type, disease severity according to self-reported Expanded Disease Severity Scale (EDSS), healthcare resource use, and medication use. In addition, information related to employment and early retirement was collected. EQ-5D-VAS and Multiple Sclerosis Impact Scale-29 (MSIS-29) instruments were used to collect quality-of-life data, and Fatigue Severity Scale (FSS) instrument for evaluating fatigue. Patients were stratified based on their disease type (relapsing-remitting MS (RRMS), secondary progressive MS (SPMS), primary progressive MS (PPMS)) and disease severity. The data were primarily analyzed using summary statistics.Results: SPMS had the highest annual total cost (71,177€) followed by PPMS (51,082€) and RRMS (36,492€). Early retirement covered the greatest share of costs in RRMS (39%) and SPMS (43%). In PPMS, early retirement and professional care were the two most equally important cost drivers, contributing together 56% of the total costs. Direct healthcare costs were responsible for 33%, 19%, and 18% of total costs in RRMS, SPMS, and PPMS. The mean EDSS in RRMS, SPMS, and PPMS were 2.5, 5.5, and 5.9, respectively. Differences in the quality-of-life were observed with both disease specific (MSIS-29) and generic (EQ-5D-VAS) instruments. The mean utility value from EQ-5D among patients with RRMS, SPMS, and PPMS was 0.76, 0.52, and 0.49, respectively. In addition, patients with SPMS and PPMS were more likely to report fatigue than patients with RRMS.Conclusions: MS phenotype has an impact on costs and quality-of-life of the patients. Early retirement seems to be one of the most important contributors to MS-related costs.

RESUMO

OBJECTIVES: To measure the association between spousal depression, general health, fatigue and sleep, and future care recipient healthcare expenditures and emergency department (ED) use. DESIGN: Prospective cohort study. SETTING: Health and Retirement Study. PARTICIPANTS: Home-dwelling spousal dyads in which one individual (care recipient) was aged 65 and older and had one or more activity of daily living or instrumental activity of daily living disabilities and was enrolled in Medicare Part B (N = 3,101). EXPOSURE: Caregiver sleep (Jenkins Sleep Scale), depressive symptoms (Center for Epidemiologic Studies Depression-8 Scale), and self-reported general health measures. MEASUREMENTS: Primary outcome was care recipient Medicare expenditures. Secondary outcome was care recipient ED use. Follow-up was 6 months. RESULTS: Caregiver depressive symptoms score and six of 17 caregiver well-being measures were prospectively associated with higher care recipient expenditures after minimal adjustment (P < .05). Higher care recipient expenditures remained significantly associated with caregiver fatigue (cost increase, $1,937, 95% confidence interval (CI) = $770-3,105) and caregiver sadness (cost increase, $1,323, 95% CI = $228-2,419) after full adjustment. Four of 17 caregiver well-being measures, including severe fatigue, were significantly associated with care recipient ED use after minimal adjustment (P < .05). Greater odds of care recipient ED use remained significantly associated with caregiver fatigue (odds ratio (OR) = 1.24, 95% CI = 1.01-1.52) and caregiver fair to poor health (OR = 1.23, 95% CI = 1.04-1.45) after full adjustment. Caregiver total sleep score was not associated with care recipient outcomes. CONCLUSION: Poor caregiver well-being, particularly severe fatigue, is independently and prospectively associated with higher care recipient Medicare expenditures and ED use.

RESUMO

BACKGROUND: Major depressive disorder (MDD) is a debilitating psychiatric illness with a high cost burden. This analysis evaluates the cost-effectiveness of adjunctive brexpiprazole versus comparator branded adjunctive treatment for MDD and background antidepressant therapy (ADT) alone from a US payer perspective. METHODS: An economic model was developed to assess the cost-effectiveness of brexpiprazole versus comparator adjunctive treatment and ADT alone on total direct medical costs using a 6-week cycle time frame for a total of 48 weeks, with treatment response and remission as primary outcomes. The model consisted of 3 parts, 1 to represent the acute treatment phase and 2 to represent the maintenance stage. RESULTS: In the base-case analysis, brexpiprazole as reference treatment resulted in cost per additional responder ranging from $19,442-$48,745 and cost per additional remitter ranging from $27,196-$71,839 versus comparator treatments over 48 weeks. Sensitivity analyses showed treatment with brexpiprazole was more costly, but more clinically effective in all probabilistic simulations. LIMITATIONS: This representation of disease natural history over 48 weeks may not account for all possible health states. Resource utilization on treatment was estimated using the resource use data from previous trials, and may overestimate medical costs compared to the real-world setting. Treatment comparators were limited to branded therapies, and head-to-head studies were not available to obtain data inputs. CONCLUSION: Compared to other branded adjunctive therapies, brexpiprazole increases response and remission at 6 weeks; medical care cost savings were observed with the use of brexpiprazole. These findings may assist clinicians and formulary decision makers when selecting treatment for MDD.

RESUMO

BACKGROUND: To examine the effectiveness and acceptability of an 8-week individual tailored cognitive behavioural therapy (CBT) intervention for the treatment of depressive symptoms in those newly diagnosed with multiple sclerosis. METHODS: The current study presents a pilot, parallel group randomized controlled trial (RCT) with an allocation ratio of 1:1 conducted in a large research and teaching hospital in Melbourne, Australia. 30 individuals with a mean age of 36.93 years (SD = 9.63) who were newly diagnosed with multiple sclerosis (MS) (X = 24.87 months, SD = 15.61) were randomized to the CBT intervention (n = 15) or treatment as usual (TAU) (n = 15). The primary outcome was level of depressive symptoms using the Beck Depression Inventory-II (BDI-II). Secondary outcomes were level of anxiety, fatigue and pain impact, sleep quality, coping, acceptance of MS illness, MS related quality of life, social support, and resilience. Tertiary outcomes were acceptability and adherence to the intervention. RESULTS: Large between group treatment effects were found for level of depressive symptoms at post and at 20 weeks follow-up (d = 1.66-1.34). There were also small to large group treatment effects for level of anxiety, fatigue and pain impact, sleep quality, MS related quality of life, resilience, and social support at post and at 20 weeks follow-up (d = 0.17-1.63). There were no drop-outs and participants completed all treatment modules. All participants reported the treatment as 'very useful', and most (73.4%) reported that the intervention had addressed their problems 'completely'. CONCLUSIONS: These data suggest that the tailored early intervention is appropriate and clinically effective for the treatment of depressive symptoms in those newly diagnosed with MS. A larger RCT comparing the CBT intervention with an active comparative treatment with longer term follow-up and cost effectiveness analyses is warranted. The pilot trial has been retrospectively registered on 28/04/2016 with the ISRCTN registry (trial ID ISRCTN10423371).

RESUMO

Unexplained fatigue is not infrequent in the community. It presents a number of challenges to the primary care physician and particularly if the clinical examination and routine investigations are normal. However, while fatigue is a feature of many common illnesses, it is the main problem in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME). This is a poorly understood condition that is accompanied by several additional symptoms which suggest a subtle multisystem dysfunction. Not infrequently it is complicated by sleep disturbance and alterations in attention, memory and mood.Specialised services for the diagnosis and management of CFS/ME are markedly deficient in the UK and indeed in virtually all countries around the world. However, unexplained fatigue and CFS/ME may be confidently diagnosed on the basis of specific clinical criteria combined with the normality of routine blood tests. The latter include those that assess inflammation, autoimmunity, endocrine dysfunction and gluten sensitivity. Early diagnosis and intervention in general practice will do much to reduce patient anxiety, encourage improvement and prevent expensive unnecessary investigations.There is presently an on-going debate as to the precise criteria that best confirms CFS/ME to the exclusion of other medical and psychiatric/psychological causes of chronic fatigue. There is also some disagreement as to best means of investigating and managing this very challenging condition. Uncertainty here can contribute to patient stress which in some individuals can perpetuate and aggravate symptoms. A simple clinical scoring system and a short list of routine investigations should help discriminate CFS/ME from other causes of continued fatigue.

RESUMO

BACKGROUND: Although it is well recognized that people with multiple sclerosis (MS) may experience impairments in addition to limited mobility, there has been little effort to study their relative importance to patients with the condition. The objective of this study was to assess patient preferences for addressing various MS symptoms. METHODS: This study was conducted at Tufts Medical Center, Boston, Massachusetts. We developed a national online survey of MS patients and neurologists to estimate the value each group places on treating specific MS symptoms. Each respondent was presented with two randomly selected scenarios with different symptoms and treatments. MS patients were asked about their own preferences, whereas neurologists were asked to consider what a patient of theirs would do or think in each scenario. We used a bidding game approach to elicit respondents' willingness to pay (WTP) for the treatments. RESULTS: To treat mobility alone, WTP for MS patients averaged US$410-US$520 per month, depending on the scenario. For paired symptoms, MS patients would pay most to treat mobility and upper limb function (US$525/month) or mobility and cognition (US$514/month), somewhat less to treat mobility and eyesight (US$445/month), and least to treat mobility and fatigue (US$371/month). Patient WTP values increased with income and education. Neurologists believed their patients would be willing to pay US$216-US$249 per month to treat mobility alone, depending on the scenario. For paired symptoms, neurologists believed patients would pay most to treat mobility and fatigue (US$263/month) and least to treat mobility and upper limb function (US$177/month). CONCLUSION: Our findings suggest MS patients may value one outcome (e.g., improved arm and hand coordination) over another (e.g., less fatigue). Further, MS patients and neurologists may rank the importance of treating various symptoms differently. Given this potential mismatch, it is crucial for MS patients and their clinicians to discuss treatment priorities that take into account patient preferences.

RESUMO

Health care providers need to be aware that stress complaints that result from deployment can emerge even after many years. This has important implications for health care policies. The main aim of this study is to investigate the relation between the development of posttraumatic stress and other mental health complaints and the burden on (mental) health care after a deployment. For this study we used data from a large prospective cohort study on stress-factors related to deployment in 1007 Dutch soldiers, who were deployed to Afghanistan. Participants were assessed at six follow up times up until five years after deployment. In a Generalized Estimated Equations model we estimated the relation between mental health complaints and the utilization of psychological treatment and a general practitioner, respectively. Moreover, we studied the relation between mental health complaints and health care costs using bootstrap techniques. The results showed that higher scores for PTSD, depression and fatigue relate to increased use of a psychologist. And lower PTSD scores and higher depression, anxiety and somatization scores relate to increased odds to visit a GP. Furthermore, mental health complaints relate to higher costs. In conclusion, monitoring soldiers is important in order to be informed on the current demand for (mental) health care to satisfy the health care need of veterans. Early treatment, which is enabled by lowering barriers to care, relates to positive results and therefore, lower health care costs.

RESUMO

: This paper highlights some key concepts related to fatigue and the seminal role of the 1981 Ciba Foundation Symposia "Human Muscle Fatigue: Physiological Mechanisms" chaired by R.H.T. Edwards in consolidating key ideas that have moved the study of fatigue forward since that time. I also consider these concepts in their historical context via the pioneering work of the Italian physiologist and social activist Angelo Mosso in the late 1800s. Finally, fatigue as a multidimensional concept with implications beyond muscle physiology is considered.

RESUMO

One of the most recent food trends is the quest for products that provide 'sustained energy'; a term that is garnering considerable attention within the marketplace. Often, 'sustained energy' health claims are based on a food's post-prandial glycaemic response. However, are generalised health claims regarding 'sustained energy' valid when only supported by glycaemic response data? Without context, the short answer is: probably not. Health claims that link sustained energy to a glycaemic response, or any other attribute of a food or diet, require context to ensure that the public correctly interprets and experiences the claimed effect and is not misled in their quest for healthy foods that impose the desired physiological benefit.

RESUMO

OBJECTIVE: To assess the cost outcomes of patients with a history of depression and clinically significant fatigue. METHODS: Adults with ≥ 2 claims with depression diagnosis codes identified from the HealthCore Integrated Research Database were invited to participate in this study linking survey data with retrospective claims data (12-mo presurvey and postsurvey periods). Patient surveys included measures for depression (Quick Inventory of Depressive Symptomatology), fatigue (Fatigue Associated with Depression Questionnaire), anxiety (7-item Generalized Anxiety Disorder scale), sleep difficulty (Athens Insomnia Scale), and pain (Brief Pain Inventory). After adjusting for demographic and clinical characteristics using propensity scores, postsurvey costs were compared between patients with and without fatigue using nonparametric bootstrapping methods. RESULTS: Of the 1982 patients who had completed the survey and had complete claims data, 653 patients had significant levels of fatigue. Patients with fatigue reported significantly higher scores, indicating greater severity, on measures of depression, pain, sleep difficulty, and anxiety (all p < 0.05). These patients also had higher levels of overall medication use and were more likely to have lower measures of socioeconomic status than patients without significant levels of fatigue (all p < 0.05). Mean annual total costs were greater for patients with fatigue than those without fatigue ($14,462 vs $9971, respectively, p < 0.001). These cost differences remained statistically significant after adjusting for clinical and demographic differences. CONCLUSIONS: Clinically significant fatigue appears to add to the economic burden of depression. This reinforces the need for aggressive treatment of all symptoms and further examination of the variability of this relationship as patients approach remission.

RESUMO

OBJECTIVES: The aim is to assess the prevalence of comorbidities and to further analyse to which degree fatigue can be explained by comorbidity burden, disease activity, disability and gross domestic product (GDP) in patients with rheumatoid arthritis (RA). METHODS: Nine thousands eight hundred seventy-four patients from 34 countries, 16 with high GDP (>24.000 US dollars [USD] per capita) and 18 low-GDP countries (<24.000 USD) participated in the Quantitative Standard monitoring of Patients with RA (QUEST-RA) study. The prevalence of 31 comorbid conditions, fatigue (0-10 cm visual analogue scale [VAS] [10=worst]), disease activity in 28 joints (DAS28), and physical disability (Health Assessment Questionnaire score [HAQ]) were assessed. Univariate and multivariate linear regression analyses were performed to assess the association between fatigue and comorbidities, disease activity, disability and GDP. RESULTS: Overall, patients reported a median of 2 comorbid conditions of which hypertension (31.5%), osteoporosis (17.6%), osteoarthritis (15.5%) and hyperlipidaemia (14.2%) were the most prevalent. The majority of comorbidities were more common in high-GDP countries. The median fatigue score was 4.4 (4.8 in low-GDP countries and 3.8 in high-GDP countries, p<0.001). In low-GDP countries 25.4% of the patients had a high level of fatigue (>6.6) compared with 23.0% in high-GDP countries (p<0.001). In univariate analysis, fatigue increased with increasing number of comorbidities, disease activity and disability in both high- and low-GDP countries. In multivariate analysis of all countries, these 3 variables explained 29.4% of the variability, whereas GDP was not significant. CONCLUSIONS: Fatigue is a widespread problem associated with high comorbidity burden, disease activity and disability regardless of GDP.

RESUMO

STUDY OBJECTIVES: We aimed to examine various sleep measures as determinants of sickness absence while considering confounders. DESIGN: Nationally representative Health 2000 Survey linked with sickness absence data from the Finnish Social Insurance Institution. SETTING: Finland. PARTICIPANTS: Working-aged women (n = 1,875) and men (n = 1,885). INTERVENTIONS: N/A. MEASUREMENTS AND RESULTS: Insomnia-related symptoms, early morning awakenings, being more tired during daytime than other people of same age, use of sleeping pills, excessive daytime sleepiness, probable sleep apnea (4 items about snoring/apnea), and reporting that sleep duration varies between different seasons were examined as determinants of sickness absence over a 7.2 year follow-up. Poisson and gamma regression models were fitted. After adjusting age, all examined sleep disturbances except excessive daytime sleepiness were associated with sickness absence among men (RRs 1.3-2.5). Among women, after adjusting for age, insomnia-related symptoms, early morning awakenings, being more tired than others, and use of sleeping pills were associated with sickness absence (RRs 1.4-1.8). After further adjustments for education, working conditions, health behaviors, and objectively measured mental and somatic health, the associations somewhat attenuated but mainly remained. The optimal sleep duration with the lowest risk of sickness absence was 7.6 hours for women and 7.8 hours for men. Although persistence of other health problems could affect the estimates, direct costs due to sickness absence could decrease by up to 28% if sleep disturbances could be fully addressed. CONCLUSIONS: This study highlights the need for prevention of sleep disturbances and promotion of optimal sleep length to prevent sickness absence.

RESUMO

BACKGROUND: Many patients on maintenance dialysis experience significant sleepiness and fatigue. However, the influence of the hemodialysis (HD) day and circadian rhythms on patients' symptoms have not been well characterized. We sought to use ecological momentary assessment to evaluate day-to-day and diurnal variability of fatigue, sleepiness, exhaustion and related symptoms in thrice-weekly maintenance HD patients. METHODS: Subjects used a modified cellular phone to access an interactive voice response system that administered the Daytime Insomnia Symptom Scale (DISS). The DISS assessed subjective vitality, mood, and alertness through 19 questions using 7- point Likert scales. Subjects completed the DISS 4 times daily for 7 consecutive days. Factor analysis was conducted and a mean composite score of fatigue-sleepiness-exhaustion was created. Linear mixed regression models (LMM) were used to examine the association of time of day, dialysis day and fatigue, sleepiness, and exhaustion composite scores. RESULTS: The 55 participants completed 1,252 of 1,540 (81%) possible assessments over the 7 day period. Multiple symptoms related to mood (e.g., feeling sad, feeling tense), cognition (e.g., difficulty concentrating), and fatigue (e.g., exhaustion, feeling sleepy) demonstrated significant daily and diurnal variation, with higher overall symptom scores noted on hemodialysis days and later in the day. In factor analysis, 4 factors explained the majority of the observed variance for DISS symptoms. Fatigue, sleepiness, and exhaustion loaded onto the same factor and were highly intercorrelated. In LMM, mean composite fatigue-sleepiness-exhaustion scores were associated with dialysis day (coefficient and 95% confidence interval [CI] 0.21 [0.02 - 0.39]) and time of day (coefficient and 95% CI 0.33 [0.25 - 0.41]. Observed associations were minimally affected by adjustment for demographics and common confounders. CONCLUSIONS: Maintenance HD patients experience fatigue-sleepiness-exhaustion symptoms that demonstrate significant daily and diurnal variation. The variability in symptoms may contribute to poor symptom awareness by providers and greater misclassification bias of fatigue related symptoms in clinical studies.

RESUMO

Side effects or toxicities are frequent, undesirable companions of almost all forms of non-surgical cancer therapy. It is unusual for patients to complete treatment with radiation or chemotherapy without experiencing at least one form of therapy-associated tissue injury or systemic side effect. Often, toxicities do not occur as solitary events; rather, they result in clusters of symptoms that share a common biological aetiology. Like any disease, cancer treatment-related toxicities (CTRTs) vary in their severity. But, in contrast to most diseases in which incidence is described as being present or absent, the current approach to CTRT typically limits reporting to severe cases only. Not only does this dilute the frequency with which CTRTs occur, but it also undermines our ability to determine the full burden of their impact and to accurately assess the cost effectiveness of potential toxicity interventions. In this article, we report the results of a directed literature review for the years 2000-2012, in which we studied and compared three tissue-based toxicities (nausea and vomiting, diarrhoea, and oral mucositis) and one systemic toxicity (fatigue). Our results confirm the heavy burden of resource use and cost associated with CTRTs. The inclusion of fatigue in our analysis provided an opportunity to compare and contrast a toxicity in which there are both acute and chronic consequences. Our findings also demonstrate a number of challenges to, and opportunities for, future study. Among the most obvious are the lack of provider consistency in diagnosis and grading, especially when there is no global agreement on severity scales. Compounding this inconsistency is the disconnect between healthcare providers and patients that exists when describing toxicity severity and impact. In many cases, cancer can be thought of as a chronic disease that requires prolonged but episodic treatment once the acute disease is eradicated. This change reflects increasing treatment successes, but it also implies that the burden of CTRTs will be expanded and prolonged. Creation of hierarchical attribution of costs in the presence of simultaneous CTRTs, accurate coding, and consistent tracking tools for toxicities will be imperative for effective appraisal of the costs associated with cancer treatment regimen toxicities.

RESUMO

BACKGROUND: Fatigue is a common and troubling symptom for people with multiple sclerosis (MS). AIM: To evaluate the effectiveness and cost-effectiveness of a six-session group-based programme for managing MS-fatigue (Fatigue: Applying Cognitive behavioural and Energy effectiveness Techniques to lifeStyle (FACETS)). METHODS: Three-centre parallel arm randomised controlled trial with economic evaluation. Patients with MS and significant fatigue were randomised to FACETS plus current local practice (FACETS) or current local practice alone (CLP), using concealed computer-generated randomisation. Participant blinding was not possible. Primary outcomes were fatigue severity (Fatigue Assessment Instrument), self-efficacy (Multiple Sclerosis-Fatigue Self-Efficacy) and disease-specific quality of life (Multiple Sclerosis Impact Scale (MSIS-29)) at 1 and 4 months postintervention (follow-up 1 and 2). Quality adjusted life years (QALYs) were calculated (EuroQoL 5-Dimensions questionnaire and the Short-form 6-Dimensions questionnaire). RESULTS: Between May 2008 and November 2009, 164 patients were randomised; primary outcome data were available for 146 (89%). Statistically significant differences favour the intervention group on fatigue self-efficacy at follow-up 1 (mean difference (MD) 9, 95% CI (4 to 14), standardised effect size (SES) 0.54, p=0.001) and follow-up 2 (MD 6, 95% CI (0 to 12), SES 0.36, p=0.05) and fatigue severity at follow-up 2 (MD -0.36, 95% CI (-0.63 to -0.08), SES -0.35, p=0.01) but no differences for MSIS-29 or QALYs. No adverse events reported. Estimated cost per person for FACETS is £453; findings suggest an incremental cost-effectiveness ratio of £2157 per additional person with a clinically significant improvement in fatigue. CONCLUSIONS: FACETS is effective in reducing fatigue severity and increasing fatigue self-efficacy. However, it is difficult to assess the additional cost in terms of cost-effectiveness (ie, cost per QALY) as improvements in fatigue are not reflected in the QALY outcomes, with no significant differences between FACETS and CLP. The strengths of this trial are its pragmatic nature and high external validity. TRIAL REGISTRATION: Current Controlled Trials ISRCTN76517470.

RESUMO

BACKGROUND: Multiple sclerosis (MS) is a common cause of neurological disability in young adults. The TRIBUNE study provides a detailed exploration of costs in relation to relapses and disease severity, and assesses the quality of life impact on MS patients in terms of utilities, fatigue and activities of daily living (ADL). METHODS: Patients in five European countries (France, Germany, Italy, Spain and the United Kingdom) completed a self-administered web-based questionnaire capturing information on demographics, disease characteristics and severity (EDSS), co-morbidities, relapses, resource consumption, utilities, fatigue, and activities of daily living. RESULTS: In total, 1261 MS patients completed the questionnaire. More than half of the patients (68%) had the relapsing-remitting form of the disease; 87% of the sample reported receiving MS treatments. Costs were higher with advancing disease severity; for mild patients (EDSS score ≤ 3) the costs ranged between €13,534 and €22,461 across countries; for moderate (EDSS score 4 - 6.5) between €28,524 and €43,948; for severe (EDSS ≥ 7) between €39,592 and €65,395. Relapses were also associated with increasing costs; the difference in the cost per patient per year for relapsing-remitting patients with EDSS score ≤ 5 that did experience at least one relapse during the past 12 months and those who did not ranged between €3321 and €9430. The quality of life of patients decreased with disease progression and existence of relapses. CONCLUSION: The TRIBUNE study provides an important update on the economic burden of MS in an era of more widespread use of disease-modifying therapies. It explores the cost of MS linked to relapses and disease severity, and examines the impact of MS on additional health outcomes beyond utilities such as ADL and fatigue.

RESUMO

The majority of people affected by Multiple Sclerosis (paMS) experience severe and disabling fatigue. A recent randomised controlled trial (RCT) showed that cognitive behaviour therapy with a clinical psychologist was an effective treatment for MS fatigue. An Internet-based version of this intervention, MS Invigor8, was developed for the current study using agile design and input from paMS. MS Invigor8 includes eight tailored, interactive sessions. The aim was to test the feasibility and potential efficacy and cost-effectiveness of the programme in a pilot RCT. 40 patients were randomised to MS Invigor8 (n=23) or standard care (n=17). The MS Invigor8 group accessed sessions over 8-10 weeks and received up to three 30-60min telephone support sessions. Participants completed online standardised questionnaires assessing fatigue, mood, quality of life and service use at baseline and 10 weeks follow-up. Large between group treatment effects were found for the primary outcomes of fatigue severity (d=1.19) and impact (d=1.02). The MS Invigor8 group also reported significantly greater improvements in anxiety, depression and quality-adjusted life years. These data suggest that Internet-based CBT may be a clinically and cost-effective treatment for MS fatigue. A larger RCT with longer term follow-up is warranted.
