Self-reported burden among caregivers of patients with multiple sclerosis

Understanding Diverse Caregiver Experiences and Their Impact on Caregiver Burden in Multiple Sclerosis

BACKGROUND: For 80% of people living with multiple sclerosis (MS), informal care is provided by a caregiver. Caregivers spend an average of 6.5 hours a day providing care, which equates to nearly full-time, unpaid work. Although it is widely accepted that informal caregivers play an essential support role in the lives of people with MS, there is a general paucity of MS caregiver research. The findings of the few available research studies are often interpreted from a clinical perspective, without consideration of the many sociocultural aspects that produce a widely heterogeneous population of caregivers and care recipients. For many caregivers, caregiving can be accompanied by considerable burden, which can have a negative impact on their mental and physical health. However, with the lack of diverse caregiver research available, the full extent of the caregiver experience, burdens, and unmet needs is still relatively unknown. In this review, we discuss the key contributing factors to caregiver burden in MS across diverse caregiving groups, identify gaps in our understanding of caregiving responsibilities as they contribute to caregiver burden, and discuss potential strategies and interventions to reduce caregiver burden. We examine these topics from the clinician, caregiver, and care recipient perspectives.

Association between chronic illnesses in older adults and caregiver burden: a cross sectional study in the United States

OBJECTIVES

Caregiver burden is a growing social issue with an increase in the number of older adults with chronic illnesses. We analyzed the association between chronic illnesses among older adults and caregiver burden in financial, emotional, and physical domains, adjusting for caregiver and older adult characteristics.

METHOD

We used secondary data from the 2022 National Health and Aging Trends Study and the 2022 National Study of Caregiving. Logistic regression analyses was used to assess associations between nine illnesses and each caregiver burden in 1,419 participants.

RESULTS

Dementia was significantly associated with caregiver burden related to emotional difficulty (odds ratio [OR] = 2.04; 95% confidence interval [CI], 1.34-3.09) and physical difficulty (OR = 1.67, 95% CI, 1.01-2.78), but not financial difficulty. Furthermore, relationship with older adults, positive and negative self-esteem, the number of assistive activities of caregivers, and gender and physical capacity of older adults were significantly associated with caregiver burden.

CONCLUSION

These findings clarify the definition of caregiver burden and provide integrated results on caregiver burden in chronic illnesses and the characteristics of caregivers and older adults.

Absenteeism and presenteeism among caregivers of chronic diseases: A systematic review and meta-analysis

INTRODUCTION

Productivity-adjusted life-year (PALY) is a relatively new measure for quantifying the impact of disease on productivity. This study aims to systematically review the productivity factors such as absenteeism and presenteeism among informal caregivers of patients with a wide range of chronic health conditions to inform the PALY quantifications.

METHOD

A literature search across MEDLINE, Embase, EconLIT, PsychInfo, and CINAHL identified 3578 studies from which a final 23 studies were included in the analysis. To explore the pooled estimate of caregiver absenteeism/presenteeism across diseases and possible drivers, a meta-analysis and meta-regression were conducted using studies where relevant data was available.

RESULT

The pooled proportion for absenteeism, presenteeism, and work productivity loss (WPL) was 14% (95% Confidence Interval [CI]:9-19%; I2 = 96.3%), 32% (95% CI:22-42%; I2 = 98.0%) and 44% (95% CI:35-53%; I2 = 95.4%) respectively with a high a level of heterogeneity. Factors such as the disease type, and disease severity can influence the caregivers' work productivity.

CONCLUSION

The data derived in this study will enable the derivation of productivity indices to estimate PALY among caregivers. Future studies can explore the work productivity impact among caregivers of patients with other chronic conditions where they have a significant role but are unexplored, and severity-wise studies in conditions such as stroke and dementia to understand the caregivers' societal productivity impact.

DigiTRAC: Qualitative insights from knowledge users to inform the development of a Digital Toolkit for enhancing resilience among multiple sclerosis caregivers

BACKGROUND

Resilience-promoting resources are critically needed to support positive caregiving experiences for multiple sclerosis (MS) caregivers. A digital toolkit offers a flexible way to access and use evidence-based resources that align with MS caregivers' interests and needs over time.

OBJECTIVE

We explored the perspectives of key knowledge users regarding content areas, features, and other considerations to inform an MS caregiver resilience digital toolkit.

METHODS

Twenty-two individuals completed a demographic survey as part of this study: 11 MS family caregivers, 7 representatives of organizations providing support services for people with MS and/or caregivers, and 4 clinicians. We conducted nine semi-structured individual interviews and two focus groups. Data were analyzed using content analysis.

RESULTS

Participants recommended that a digital toolkit should include content focused on promoting MS caregivers' understanding of the disease, its trajectory and available management options, and enhancing caregiving skills and caregivers' ability to initiate and maintain behaviours to promote their own well-being. Features that allow for tracking and documenting care recipients' and caregivers' experiences, customization of engagement, and connectivity with other sources of support were also recommended. Participants suggested a digital toolkit should be delivered through an app with web browser capabilities accessible on smartphones, tablets, or laptops. They also acknowledged the need to consider how users' previous technology experiences and issues related to accessibility, usability, privacy and security could influence toolkit usage.

CONCLUSION

These findings will guide future toolkit development and evaluation. More broadly, this study joins the chorus of voices calling for critical attention to the well-being of MS family caregivers.

Burden of Wilson Disease among patients and care partners in the United States: results from a cross-sectional survey

OBJECTIVE

This study assessed the burden of Wilson Disease (WD) among patients and care partners (WD-CPs) in the US and compared it to a US general population of adults (GPs) and care partners (GP-CPs).

METHODS

This cross-sectional, self-reported survey included patients with WD and WD-CPs aged ≥18 years recruited through the Wilson Disease Association (WDA), while data for GPs and GP-CPs were obtained from the 2022 National Health and Wellness Survey. GPs and GP-CPs were propensity score matched (3:1) with WD patients and WD-CPs for demographics and health characteristics. Bivariate analysis evaluated differences in comorbidity burden and health-related outcomes of the WD cohorts compared to matched GP cohorts.

RESULTS

Thirty-seven patients with WD and 53 WD-CPs completed the survey. Most patients reported some treatment burden (73.3%), experienced sleep problems (60%), and visited a healthcare provider (HCP) in the past 6 months (91.9%). Compared with matched GPs, patients with WD had a significantly higher mortality risk (p < .001) and reported greater rates of chronic liver disease, cirrhosis (both, p < .001), migraines (p = .032), non-alcoholic steatohepatitis (p = .004), sleep problems (p = .009) and HCP visits (p = .002). Most WD-CPs (75.5%) reported high burden of caring (mean ZBI-12 score, 26.5) and more negative impact on esteem than GP-CPs.

CONCLUSION

This study highlights the burden of WD experienced by patients and WD-CPs, with patients experiencing high treatment burden, comorbidity burden and healthcare resource utilization, and WD-CPs experiencing high impact of caring, including impact on employment and self-esteem.

Caregiver Burden Associated With Pediatric Chronic Pain: A Retrospective Study Using the Pediatric Electronic Persistent Pain Outcomes Collaboration Database

OBJECTIVES

This retrospective, cross-sectional study investigated the nature and extent of burden experienced by caregivers of children and adolescents with chronic pain, and factors associated with increased caregiver burden.

METHODS

The Pediatric Electronic Persistent Pain Outcomes Collaboration database provided prospectively collected data from 1929 families attending 9 pediatric chronic pain services across Australia and New Zealand. Data included demographic information, responses to child pain and functioning measures, caregiver work impairment, and psychosocial functioning.

RESULTS

Caregivers of children with chronic pain reported work impairment associated with their child's pain (mean: 15% ± SD 25 absenteeism; 38% ± SD 29 productivity lost), significantly worse than published international population norms (large-scale community survey data), most other caregiver samples of adults and children with other chronic conditions, and adult samples with various pain conditions. Caregivers reported considerable burden in multiple psychosocial functioning domains, particularly leisure functioning, pain-related catastrophizing, and adverse parenting behaviors (with greater pain-related avoidance). Caregiver psychosocial burden was significantly associated with child psychosocial functioning (β = -0.308, P < 0.01), school absenteeism (β = 0.161, P < 0.01), physical disability (β = 0.096, P < 0.05), and pain duration (β = 0.084, P < 0.05), but not pain intensity. Caregiver work productivity loss was significantly associated with school absenteeism (β = 0.290, P < 0.01), child physical disability (β = 0.148, P < 0.01), child health care utilization (β = 0.118, P < 0.05), and worst pain intensity (β = 0.101, P < 0.05).

DISCUSSION

These results highlight the significant and varied impacts experienced by caregivers of children with chronic pain. This work is novel in reporting significant work impairment and confirms psychosocial burden in a larger sample than previous studies.

Burden of Medication Overuse in Migraine: A Cross-sectional, Population-Based Study in Five European Countries Using the 2020 National Health and Wellness Survey (NHWS)

INTRODUCTION

Overuse of medication to treat migraine attacks can lead to development of a new type of headache or significant worsening of pre-existing headache, known as medication overuse headache. However, data concerning the burden of medication overuse (MO) in migraine are limited. This study aimed to assess the humanistic burden of MO in individuals with migraine from five European countries.

METHODS

Data are from the 2020 National Health and Wellness Survey-a cross-sectional, population-based survey conducted in France, Germany, Italy, Spain, and the UK. Data were included from adults (≥ 18 years) with a self-reported diagnosis of migraine and at least one migraine attack and one headache in the past 30 days. MO was defined as (i) use of simple analgesics/over-the-counter medications on ≥ 15 days/month; or (ii) use of migraine medication, including combination analgesics, on ≥ 10 days/month. Humanistic burden of MO was assessed using the 12-Item Short-Form Health Survey (SF-12v2), EuroQol 5-Dimensions 5-Levels (EQ-5D), Short-Form 6-Dimensions (SF-6D), and Migraine Disability Assessment (MIDAS). The association of MO with humanistic burden was evaluated using generalized linear models adjusted for potential confounders in the full migraine population and in subgroups defined by headache frequency (monthly headache days [MHDs] 1-3, 4-7, 8-14, or ≥ 15).

RESULTS

Among individuals with migraine, humanistic burden (SF-12v2, SF-6D, EQ-5D, and MIDAS) was higher in individuals who reported MO (n = 431) versus no MO (n = 3554), even after adjustment for confounding variables (p < 0.001 for all measures). MIDAS and EQ-5D scores were higher in individuals with MO than without, at all levels of headache frequency. For SF-12v2 and SF-6D, differences between groups with/without MO were seen only at lower levels of headache frequency (MHD 1-3 and 4-7).

CONCLUSION

Among people with migraine, those who report MO face a greater humanistic burden than those without MO, irrespective of headache frequency.

Physical Activity Together for Multiple Sclerosis (PAT-MS): A randomized controlled feasibility trial of a dyadic behaviour change intervention

Background

Many people with advanced multiple sclerosis (MS) and their care-partners do not engage in sufficient physical activity (PA) for health benefits. We developed "Physical Activity Together for MS (PAT-MS)", a 12-week dyadic behavioural intervention, to promote PA among these dyads. Herein, we evaluated the feasibility of PAT-MS before a definitive trial.

Methods

A randomized controlled feasibility trial, with 1:1 allocation into the intervention or wait-list control condition. Predefined progression criteria included rates of recruitment, retention, safety, participant satisfaction and adherence. Changes in self-reported and accelerometer-measured PA were assessed at baseline and post-intervention using mixed-factor ANOVAs. Effects sizes were calculated as Cohen's d.

Results

The recruitment rate (i.e., 20 participants in 10 months) was not acceptable. However, retention (80%) was acceptable. No serious adverse events were reported. There were high levels of participant satisfaction with the intervention (content (median = 6 out of 7), facilitator (median = 7 out of 7), and delivery (median = 5 out of 7)) and adherence (92% of the group sessions, 83% of the individual support calls, and 80% of the practice activities were completed). There were statistically significant time-by-condition interactions on self-reported PA, steps/day, and %wear time and minutes in sedentary behaviour, and moderate-to-vigorous PA from baseline to post-intervention in people with MS and their family care-partners.

Conclusion

PAT-MS appears feasible, safe, and efficacious for PA promotion in MS dyads. We established effect size estimates to power a future definitive trial and identified necessary methodological changes to increase the efficiency of study procedures and improve the quality of the intervention.

The Clinical and Economic Impact of Employees Who Are Care Partners of Patients with Multiple Sclerosis by Disease Severity

Background: Research on employee care partners of patients with multiple sclerosis (MS) is limited. Objectives: The clinical and economic impact on employee care partners was evaluated by MS disease severity. Methods: Employees with spouses/domestic partners with MS from the Workpartners database (Jan. 1, 2010-Dec. 31, 2019) were eligible if: spouse/partner had at least 3 MS-related (ICD-9-CM/ICD-10-CM:340.xx/G35) inpatient/outpatient/disease-modifying therapy claims within 1 year (latest claim = index date); 6-month pre-index/1-year post-index enrollment; and age 18 to 64 years. Employee care partners' demographic/clinical characteristics and direct/indirect costs were compared across predetermined MS severity categories. Logistic and generalized linear regression modeled the costs. Results: Among 1041 employee care partners of patients with MS, 358 (34.4%) patients had mild MS, 491 (47.2%) moderate, and 192 (18.4%) severe. Mean (standard error [SE]) employee care partner age was 49.0 (0.5) for patients with mild disease, 50.5 (0.4) for moderate, 51.7 (0.6) for severe; percent female care partners was 24.6% [2.3%] mild, 19.8% [1.8%] moderate, 27.6% [3.2%] severe; and mean care partner Charlson Comorbidity Index scores 0.28 (0.05) mild, 0.30 (0.04) moderate, 0.27 (0.06) severe. More care partners of patients with moderate/severe vs mild MS had hyperlipidemia (32.6%/31.8% vs 21.2%), hypertension (29.5%/29.7% vs 19.3%), gastrointestinal disease (20.8%/22.9% vs 13.1%), depression (9.2%/10.9% vs 3.9%), and anxiety 10.6%/8.9% vs 4.2%). Adjusted mean medical costs were greater for employee care partners of patients with moderate vs mild/severe disease (P<.001). Pharmacy costs (SE) were lower for employee care partners of mild vs severe/moderate patients (P<.005). Sick leave costs (SE) were greater for employee care partners of mild/severe vs moderate patients (P<.05). Discussion: Employee care partners of patients with moderate/severe vs mild MS had more comorbidities (ie, hypertension, gastrointestinal disease, depression, and anxiety) and higher pharmacy costs. Employee care partners of patients with moderate vs mild/severe MS had higher medical and lower sick leave costs. Treatment strategies that improve patient outcomes may reduce employee care partner burden and lower costs for employers in some instances. Conclusions: Comorbidities and direct/indirect costs of employees whose spouses/partners have MS were considerable and varied with MS severity.

The Associations between Insomnia Severity and Health Outcomes in the United States

Little is known about the associations between insomnia severity, insomnia symptoms, and key health outcomes. Using 2020 United States National Health and Wellness Survey (NHWS) data, we conducted a retrospective, cross-sectional analysis to determine the associations between insomnia severity and a number of health outcomes germane to patients (health-related quality of life (HRQoL), employers and government (workplace productivity), and healthcare payers (healthcare resource utilization (HCRU)). The Insomnia Severity Index (ISI) questionnaire was used to evaluate overall insomnia severity. HRQoL was assessed using the physical and mental component summary scores of the Short Form-36v2 (SF-36v2) questionnaire, and health utility status was measured using the Short Form-6D (SF-6D) and EuroQoL-5D (EQ-5D) questionnaires. Workplace productivity was measured using the Work Productivity and Activity Impairment (WPAI) questionnaire. After adjusting for confounders, greater insomnia severity was significantly associated with worsened quality of life, decreased productivity, and increased HCRU in an apparent linear fashion. These findings have important implications for future research, including the need for specific assessment of insomnia symptoms and their impact on key health outcomes.

Burden and resources in caregivers of people with multiple sclerosis: A qualitative study

BACKGROUND

Caregivers of people with Multiple Sclerosis are required to provide ongoing assistance especially during the advanced stages of the disease. They have to manage interventions and assume responsibilities which significantly impact both their personal quality of life and family's dynamics.

OBJECTIVE

A qualitative phenomenological study was carried out to understand the experience of burden in caregivers and their resources to manage it. The study also explores how healthcare services involved in the Multiple Sclerosis Clinical Pathway respond to the needs of well-being of patients and family members.

METHODS

17 caregivers were involved in focus groups and in semi-structured individual interviews.

RESULTS

Fatigue is experienced by all respondents and it starts when physical disabilities increase or when people become aware of them. Many caregivers declare that they refer to intrinsic (love towards their relatives, patience and dedication) or extrinsic (family members, hobbies) resources to cope with the burden of assistance. Patient associations and the Multiple Sclerosis Clinical Pathway play a significant role in supporting caregivers.

CONCLUSIONS

Fatigue, loneliness, and isolation are experienced by caregivers and strongly affect their quality of life and health status. The study highlights caregivers' need to reconcile working times with care times, to give more space to self-care and to have moments to share their experiences with someone else. These needs should be at the core of health policies in order to avoid physical and emotional breakdowns which could lead to the rupture of the relational balance on which home care is based.

Profiles of resilience in multiple sclerosis family care-partners: A Canadian cross-sectional study

Background

Psychological resilience may play an important role in protecting multiple sclerosis care-partners from the negative effects of their support role. However, predictors of resilience in this population have yet to be identified.

Objectives

To identify characteristics predictive of psychological resilience in multiple sclerosis care-partners as informed by the Ecological Model of Resilience.

Methods

Informal multiple sclerosis care-partners (n = 540) completed an online survey. Psychological resilience was measured using the 25-item Connor-Davidson Resilience Scale. Sociodemographic and care-context predictors of resilience were analyzed using hierarchical regression.

Results

The mean resilience score was 59.0 (SD = 7.6) out of a possible 100. Sociodemographic variables accounted for 31% of the variance in resilience scores in multiple sclerosis care-partners. When care-context variables were incorporated into the model, 55% of variance was explained (F[7,320] = 26.824, p < 0.001). Each group of variables remained significant in both low disability and high disability models. Social support was the only individual variable that remained significant across all models (p < 0.05).

Conclusions

Multiple sclerosis care-partners differ strikingly from other caregiving populations. Both sociodemographic and care-context variables were found to promote or hinder resilience in multiple sclerosis care-partners. Social support, in particular, may be an important target for promoting resilience in multiple sclerosis care-partners and could be leveraged in future initiatives.

Towards conceptual convergence: A systematic review of psychological resilience in family caregivers of persons living with chronic neurological conditions

Background

The demand for family caregiving in persons with chronic neurological conditions (CNCs) is increasing. Psychological resilience may empower and protect caregivers in their role. Thus, a synthesis of resilience evidence within this specific population is warranted.

Aim

In this systematic review we aimed to: (1) examine the origins and conceptualizations of resilience; (2) summarize current resilience measurement tools; and (3) synthesize correlates, predictors and outcomes of resilience in family caregivers of persons with CNCs.

Design

We sourced English articles published up to July 2020 across five databases using search terms involving CNCs, family caregivers and resilience.

Results

A total of 50 studies were retained. Nearly half (44%) of the studies used trait‐based resilience definitions, while about one third (36%) used process‐based definitions. Twelve different resilience scales were used, revealing mostly moderate to high‐resilience levels. Findings confirmed that resilience is related to multiple indicators of healthy functioning (e.g., quality of life, social support, positive coping), as it buffers against negative outcomes of burden and distress. Discordance relating to the interaction between resilience and demographic, sociocultural and environmental factors was apparent.

Conclusions

Incongruity remains with respect to how resilience is defined and assessed, despite consistent definitional concepts of healthy adaptation and equilibrium. The array of implications of resilience for well‐being confirms the potential for resilience to be leveraged within caregiver health promotion initiatives via policy and practice.

Patient or Public Contribution

The findings may inform future recommendations for researchers and practitioners to develop high‐quality resilience‐building interventions and programmes to better mobilize and support this vulnerable group.

Spillover Effects of Mental Health Disorders on Family Members' Health-Related Quality of Life: Evidence from a US Sample

OBJECTIVES

This study aims to characterize the spillover effects of selected mental health disorders (episodic mood disorder (EMD), anxiety, substance use disorder (SUD), schizophrenia, attention-deficit/hyperactivity disorder (ADHD), and dementia) on family members' health-related quality of life and to compare the magnitude of spillover effects across these types.

METHODS

Using the 2000-2015 Medical Expenditure Panel Survey, households having individuals with mental health disorders were identified. The SF-12 and EQ-5D surveys were used to acquire utility and health status scores for household members. The outcomes in households including an individual with a mental health disorder were compared to those of the control group (absence of individuals with mental health disorders in the household). We also compared a total of 15 pairs of diseases based on the SF-6D scores. A beta generalized estimating equation model was employed.

RESULTS

Average scores of utility and health status among individuals living with a member with a mental health disorder in the household were statistically lower than those of the control group and; for the SF-6D, met the minimally important difference for SUD, schizophrenia, and dementia. Differences in the SF-6D scores were statistically significant for 5 pairs of the mental health disorders: EMD-anxiety, EMD-ADHD, dementia-anxiety, dementia-ADHD, and schizophrenia-ADHD.

CONCLUSIONS

This study provides evidence of family spillover effects in mental illness using both utility and health status measures from a US representative sample. Integrating this evidence into clinical and policy decision making as well as economic evaluations would allow for a more comprehensive valuation of the societal benefits of mental and behavioral health interventions.

Self-reported burden of caregiver of adults with depression: a cross-sectional study in five Western European countries

BACKGROUND

Caregiving in depression imposes a complex health and economic burden. Moreover, there is a paucity of studies examining the impact of caregiving for adult relatives with unipolar depression (CG-UD). This study assessed the burden among CG-UD in five western European (EUR5) countries (France, Germany, Italy, Spain and the United Kingdom) compared with caregivers of adults with other chronic comorbidities (CG-OD) and general non-caregiving (non-CG) population.

METHODS

A retrospective observational study was conducted using the 2016 National Health and Wellness Survey (NHWS) in EUR5. Differences in humanistic burden (health status and health-related quality of life [HRQoL]) and economic burden (work productivity and activity impairments, health care resource utilization [HRU]) were assessed between CG-UD and CG-OD respondents. Caregiver-specific burden (caregiving responsibilities and caregiver reaction assessment [CRA]) was assessed between caregiver groups. Generalized linear models were used to compare between the groups on the outcomes after adjusting for potential confounders.

RESULTS

Of the 77,418 survey respondents examined, 1380 identified as CG-UD, 6470 as CG-OD and 69,334 as non-CG. Compared to CG-OD and non-CG, CG-UD, reported significantly lower health status (e.g., EuroQoL-5 Dimensions-5 Levels [EQ-5D-5L]: CG-UD = 0.63, CG-OD = 0.67, and non-CG = 0.73, p < 0.001) and HRQoL (e.g., mental component score: CG-UD = 35.0, CG-OD = 37.8, and non-CG = 40.7, p < 0.001). Although effect sizes were small (d < 0.2), minimal clinically important differences (MCID) were apparent for HRQoL and health status. Increased economic-related burden was observed for work and activity impairment (e.g., absenteeism: CG-UD = 32.6%, CG-OD = 26.5%, and non-CG = 14.8%, p < 0.001) and HRU (e.g., healthcare provider [HCP; mean, past 6 months]: CG-UD = 10.5, CG-OD = 8.6, and non-CG = 6.8, p < 0.001). Caregiving-specific burden was associated with experiencing a greater lack of family support (CG-UD: 2.9 vs CG-OD: 2.8, p < 0.01), impact on finances (CG-UD: 3.0 vs CG-OD: 2.9, p = 0.036), and on the caregiver's schedule (CG-UD: 3.1 vs CG-OD: 3.0, p = 0.048).

CONCLUSION

Caregivers of persons with chronic disease experience an excess humanistic and economic burden compared to the general population, with a greater burden confronting caregiver for adults with depression. These findings illustrate the far-reaching burden of depression on both the patient and the relatives who care for them.

Physical Activity Together for People With Multiple Sclerosis and Their Care Partners: Protocol for a Feasibility Randomized Controlled Trial of a Dyadic Intervention

Background

Physical activity (PA) is beneficial for all people; however, people affected by multiple sclerosis (MS) find regular PA challenging. These people may include individuals with advanced disabilities and their care partners.

Objective

The objective of this study is to determine the feasibility of a dyadic PA intervention for people with advanced MS and their care partners.

Methods

This study is a randomized controlled feasibility trial of a 12-week intervention, with 1:1 allocation into an immediate intervention condition or delayed control condition. A target of 20 people with MS–care partner dyads will be included. The outcomes will be indicators of process, resources, management, and scientific feasibility. Participant satisfaction with the intervention components will be evaluated using a satisfaction survey. The subjective experience of participation in the study will be explored using semistructured interviews.

Results

The project is funded by the Consortium of Multiple Sclerosis Centers. This protocol was approved by the Ottawa Hospital Research Ethics Board (20190329-01H) and the University of Ottawa Research Ethics Board (H-09-19-4886). The study protocol was registered with ClinicalTrials.gov in February 2020. The findings of this feasibility trial will be disseminated through presentations at community events to engage the MS population in the interpretation of our results and in the next steps. The results will also be published in peer-reviewed journals and presented to the scientific community at national and international MS conferences.

Conclusions

The data collected from this feasibility trial will be used to refine the intervention and materials in preparation for a pilot randomized controlled trial.

The Humanistic and Economic Burden of Migraine in Europe: A Cross-Sectional Survey in Five Countries

INTRODUCTION

Prior studies have estimated the burden of migraine in patients suffering from ≥ 4 monthly headache days (MHDs), but the burden experienced by migraineurs suffering from one to three (1-3) MHDs is unknown. The aim of this study was to examine the incremental burden of migraine in terms of health-related quality of life (HRQoL), impairments to work and daily activities, and healthcare resource utilization (HRU) in five European countries (France, Germany, Italy, Spain, and the UK (EU5]), by comparing migraineurs with ≥ 4 MHDs and migraineurs with 1-3 MHDs.

METHODS

The sample for this retrospective cross-sectional study was collected from the 2017 National Health and Wellness Survey (N = 62,000). The Short-Form 12-Item Health Survey Instrument, version-2 physical and mental component summary (PCS and MCS) scores, Short-Form 6-dimensions (SF-6D), EuroQoL 5-dimensions (EQ-5D) and EuroQoL visual analog scale (VAS) scores, impairments to work productivity and daily activities (Work Productivity and Activity Impairment [WPAI] Questionnaire) scores, and HRU were compared between migraineur groups with ≥ 4 MHDs (4-7, intermediate-frequency episodic migraine; 8-14, high-frequency episodic migraine; ≥ 15 chronic migraine) and the migraineur subgroup with 1-3 MHDs (low-frequency episodic migraine) using generalized linear modeling after adjusting for covariates.

RESULTS

Data from a total of 62,000 survey respondents were examined, of whom 1323 and 1569 were considered to have 1-3 MHDs and ≥ 4 MHDs (4-7 MHDs [n = 783]; 8-14 MHDs [n = 429]; ≥ 15 MHDs [n = 357]), respectively. The adjusted HRQoL was significantly lower in the 4-7 MHDs (for MCS and SF-6D scores; p < 0.0001) and 8-14 MHDs subgroups (for MCS, SF-6D, EQ-5D, and EuroQoL VAS scores, p < 0.0001; for PCS scores, p = 0.0007) than in the 1-3 MHDs subgroup. Migraineurs with 4-7 and 8-14 MHDs reported higher activity impairment and more frequent visits to healthcare providers (all p < 0.0001) and neurologists (p = 0.0006 and p < 0.0001, respectively) compared to the 1-3 MHDs subgroup. Migraineurs with ≥ 15 MHDs had significantly lower HRQoL and increased WPAI scores and HRU than the 1-3 MHDs subgroup.

CONCLUSIONS

This study provides evidence supporting the incremental burden of migraine, characterized by poorer HRQoL and increased WPAI scores and greater HRU, among migraineurs experiencing ≥ 4 MHDs compared with migraineurs experiencing 1-3 MHDs in the EU5.

Working status of caregivers for people with dementia: Analysis data from a Japanese Nationwide Survey

BACKGROUND

The prevalence of dementia has increased rapidly in Japan, while the proportion of the population accounted for by working-age individuals is facing a sharp decline. Optimizing the balance between work and caregiving for persons with dementia is a major public health issue.

AIMS

Using a nationally representative sample, this study investigated the working status of caregivers (CGs) for elderly people (care recipients) with dementia (CRDs) and assessed the effects of sociodemographic factors on this status.

METHODS

Data were obtained from the 2013 Comprehensive Survey of the Living Conditions for CRDs and CGs (the latter aged 65 years or less). Individual data of CRDs and CGs were linked, and 452 pairs were extracted. The Japanese version of the Kessler 6 (K6) with a cut-off point of 13 was used to assess general psychological distress among CGs. Multivariable logistic regression analysis with the forward selection method was used to identify the predictors of their working status.

RESULTS

Overall, the mean age of CGs was 57.1 ± 6.8 years, with 57.5% (260/452) performing paid work. Male sex, higher educational attainment, and having their own house were associated with having paid work for CGs, while higher age, spending almost all day performing nursing care, and participation in helping with toilet activities and laundry were associated with not performing paid work.

CONCLUSIONS

Several sociodemographic factors, including nursing care-related factors, are associated with the employment status of CGs. Further research should examine detailed information on CRDs' activities of daily living, behavioral and psychological symptoms, medical service use, and social support to strengthen the system of supportive services for both CRDs and their CGs.

Increased mental health care use by mothers of children with multiple sclerosis

OBJECTIVE

We compared the prevalence of physical and mental conditions and rate of health care utilization in mothers of children with multiple sclerosis (MS) (MS-mothers) with that of mothers of children without MS (non-MS-mothers).

METHODS

Using population-based administrative data from Ontario, Canada, we identified MS-mothers and non-MS-mothers, matched on maternal age at childbirth, region, and the child's age and sex at the time of MS diagnosis. We compared the prevalence of any physical condition or any mood or anxiety disorder between the cohorts, in the child's MS diagnosis year, and 5 years before and after diagnosis. We compared rates of physician visits before diagnosis, during the diagnosis year, and after the child's diagnosis using multivariable regression models with generalized estimating equations adjusting for maternal age, socioeconomic status, region of residence, and index year.

RESULTS

We identified 156 MS-mothers and 624 non-MS-mothers. MS-mothers had a higher prevalence of any physical condition and of any mood or anxiety disorder than non-MS-mothers, before, during, and after their child's diagnosis. On multivariable analysis, MS-mothers did not have higher rates of primary care visits (rate ratio [RR] 1.04; 95% confidence interval [CI] 0.90-1.20), but exhibited increased odds of having any psychiatry visits (odds ratio 1.60; 95% CI 1.10-2.31); the rate of visits did not differ when they did occur (RR 0.66; 95% CI 0.33-1.30).

CONCLUSION

Mothers of children with MS use more mental health services before and after their child's MS diagnosis than mothers of children without MS. Pediatric health care providers should consider the mental well-being of mothers and their children with MS.

The Experiences of Multiple Sclerosis Patients' Family Caregivers at the First Hospitalization of Their Patients: A Qualitative Study

BACKGROUND AND AIM

Being diagnosed with multiple sclerosis is usually accompanied by emotional trauma for patients and their families. The chronic, progressive, and unpredictable nature of the disease spells the patients' long-term need for care from their families. As soon as a diagnosis is made, family caregivers are faced with many challenges. The present study aims to identify family caregivers' experiences at the first hospitalization of their patients.

MATERIALS AND METHODS

The present study is a work of qualitative research and uses the conventional content analysis approach. It lasted from July 2019 to March 2020. The subjects were selected via purposeful sampling. To collect data, the researchers conducted in-depth, semi-structured interviews with 18 family caregivers of patients with multiple sclerosis. The collected data were analyzed using MAXQDA 2007.

RESULTS

Analysis of the data yielded three themes: peaceful environment, need for continuing full support, and religion-based coping strategies.

CONCLUSION

The findings of the present study can be used to develop support programs that address family caregivers' problems and needs to assist them in accepting and coping with the conditions of their patients, thereby increasing the quality of care provided to patients with multiple sclerosis.

Associations Between Headache-Free Days and Patient-Reported Outcomes Among Migraine Patients: A Cross-Sectional Analysis of Survey Data in Europe

INTRODUCTION

Migraine imposes a substantial burden on patients, society, and healthcare systems. This study aimed to assess the associations between the number of headache-free days (HFDs) and health-related quality of life (HRQoL), work productivity and activity impairment (WPAI), and healthcare resource utilization (HRU) in patients with migraine in the EU5 (France, Germany, Italy, Spain, and the United Kingdom).

METHODS

This retrospective cross-sectional study collected survey responses from adults aged ≥ 18 years from the 2017 National Health and Wellness Survey (N = 62,000). Migraine patients with a physician's diagnosis of migraine and who had experienced at least 4 monthly headache days in the prior month were included (N = 1569). Number of HFDs was compared with Short-Form 12-Item Survey Instrument, version 2 (SF-12v2) physical and mental component summary scores (PCS and MCS), Short-Form-6D (SF-6D) and EuroQoL-5D (EQ-5D) scores, WPAI, and HRU in migraine patients. Correlation analyses were conducted to test the bivariate associations, whereas generalized linear models were used for multivariable analyses.

RESULTS

An increase of 1 HFD was associated with average increases of 0.171, 0.306, 0.003, and 0.008 points for MCS, PCS, SF-6D utility score, and EQ-5D index score, respectively (p < 0.001 for all). Extrapolating the results to a tenfold increase in monthly HFDs corresponded to clinically meaningful increases in PCS and EQ-5D scores. An increase of 1 HFD was associated with expected average decreases in absenteeism of 3.9% and presenteeism of 2.1%. Further, an increase of 1 HFD was associated with expected decreases in HCP visits and neurologist visits of 1.0% and 4.7%, respectively.

CONCLUSION

An increase in the number of HFDs was associated with better health-related outcomes in patients suffering from migraine. Further, the results demonstrate a need for more effective treatments that can reduce migraine frequency and thus improve HRQoL, increase work productivity, and reduce both activity impairment and HRU.

Association of Unemployment and Informal Care with Stigma in Multiple Sclerosis: Evidence from the Survey on Living with Neurological Conditions in Canada

Background

Multiple sclerosis (MS) typically affects young adults during their primary productive years. We assessed the magnitude of, and factors associated with, employment status and informal care in people with MS in Canada.

Methods

Data were compiled from the nationally representative cross-sectional Survey on Living with Neurological Conditions in Canada (SLNCC), which included adolescents and adults (age ≥15 years). Employment status was categorized as currently working or not working. The frequency of informal care that people with MS received was categorized as none, less than daily, or daily. Logistic regression analyses were undertaken to identify factors associated with employment status and informal care requirements in people with MS.

Results

Of 4409 SLNCC respondents, 631 had MS, of whom 530 were included in the analysis. Of 358 respondents aged 18 to 65 years, 47.8% were not working because of MS; 44.0% reported receiving informal care, with more than half requiring daily care. For caregivers' employment, 15.5% reduced work and 8.2% stopped working because of caregiving. Greater feelings of stigmatization were associated with not working (adjusted odds ratio, 7.42 [95% CI, 2.59-21.28]) and greater informal care (adjusted odds ratio, 3.83 [95% CI, 1.84-7.96]), adjusting for sex, age, education, health-related quality of life, time since MS diagnosis, and comorbidity.

Conclusions

People who feel stigmatized because of their MS are more likely to be unemployed and to require more informal care. Further research is needed to understand the temporal nature of the association between stigma and employment, productivity loss, and informal care.

Prediction of Acute-Phase Treatment Outcomes by Adding a Single-Item Measure of Activity Impairment to Symptom Measurement: Development and Validation of an Interactive Calculator from the STAR*D and CO-MED Trials

BACKGROUND

Day-to-day functioning is impaired in major depressive disorder. Yet there are no guidelines to systematically assess these functional changes. This report evaluates prognostic utility of changes in activity impairment to inform clinical decision-making at an individual level.

METHODS

Mixed model analyses tested changes in activity impairment (sixth item of Work and Activity Impairment scale, rated 0-10) at mid-point (week 6) and end of step 1 (weeks 12-14) in the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial (n = 2697) after controlling for depression severity [Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR)]. Interactive calculators for end of step 1 remission (QIDS-SR ≤5) and no meaningful benefit (<30% QIDS-SR reduction from baseline) were developed for participants with complete data (n = 1476) and independently replicated in the Combining Medications to Enhance Depression Outcomes trial (n = 399).

RESULTS

Activity impairment improved independently with acute-phase treatment in STAR*D (F = 7.27; df = 2,2625; P < .001). Baseline to mid-point activity impairment change significantly predicted remission (P < .001, model area under the curve = 0.823) and no meaningful benefit (P < .001, area under the curve = 0.821) in the STAR*D trial. Adding activity impairment variables to depression severity measures correctly reclassified 28.4% and 15.8% remitters and nonremitters (net reclassification improvement analysis, P < .001), and 11.4% and 16.8% of those with no meaningful benefit and meaningful benefit (net reclassification improvement analysis, P < .001). The STAR*D trial model estimates accurately predicted remission (area under the curve = 0.80) and no meaningful benefit (area under the curve = 0.82) in the Combining Medications to Enhance Depression Outcomes trial and was used to develop an interactive calculator.

CONCLUSION

A single-item self-report measure of activity impairment changes independently with antidepressant treatment. Baseline to week 6 changes in activity impairment and depression severity can be combined to predict acute-phase remission and no meaningful benefit at an individual level.

Spillover Effects on Caregivers' and Family Members' Utility: A Systematic Review of the Literature

BACKGROUND

A growing body of research has identified health-related quality-of-life effects for caregivers and family members of ill patients (i.e. 'spillover effects'), yet these are rarely considered in cost-effectiveness analyses (CEAs).

OBJECTIVE

The objective of this study was to catalog spillover-related health utilities to facilitate their consideration in CEAs.

METHODS

We systematically reviewed the medical and economic literatures (MEDLINE, EMBASE, and EconLit, from inception through 3 April 2018) to identify articles that reported preference-based measures of spillover effects. We used keywords for utility measures combined with caregivers, family members, and burden.

RESULTS

Of 3695 articles identified, 80 remained after screening: 8 (10%) reported spillover utility per se, as utility or disutility (i.e. utility loss); 25 (30%) reported a comparison group, either population values (n = 9) or matched, non-caregiver/family member or unaffected individuals' utilities (n = 16; 3 reported both spillover and a comparison group); and 50 (63%) reported caregiver/family member utilities only. Alzheimer's disease/dementia was the most commonly studied disease/condition, and the EQ-5D was the most commonly used measurement instrument.

CONCLUSIONS

This comprehensive catalog of utilities showcases the spectrum of diseases and conditions for which caregiver and family members' spillover effects have been measured, and the variation in measurement methods used. In general, utilities indicated a loss in quality of life associated with being a caregiver or family member of an ill relative. Most studies reported caregiver/family member utility without any comparator, limiting the ability to infer spillover effects. Nevertheless, these values provide a starting point for considering spillover effects in the context of CEA, opening the door for more comprehensive analyses.

Measuring burden in caregivers of people with multiple sclerosis: psychometric properties of the CSI questionnaire

BACKGROUND

Understanding caregiver strain may be crucial to determine which interventions are most needed to mitigate the negative impact of caring for people with multiple sclerosis (MS). The Caregiver Strain Index (CSI) is a brief self-assessment tool for measuring the caregivers' perceived level of burden. Limited information is available on the psychometric performance of the CSI in MS.

OBJECTIVE

The objective of this study was to assess the factor structure and construct validity of the CSI in MS.

METHODS

A multicenter, cross-sectional study in adults with relapsing-remitting and primary-progressive MS (McDonald 2010 criteria) was conducted. A non-parametric item response theory (IRT) procedure, Mokken analysis, was conducted to assess the dimensional structure of the CSI. A parametric IRT model for dichotomous responses, Rasch model, was conducted to assess item characteristics. Discriminative validity was assessed comparing the distribution of its overall score between people with mild and moderate-severe disability according to the Expanded Disability Status Scale.

RESULTS

A total of 72 MS caregivers were studied. The prevalence of a high level of strain was 23.6% (n=17). Internal reliability was high (Cronbach's alpha =0.91). According to Mokken analysis, CSI represented a unidimensional construct of caregiver burden although two of the total 13 items (#1 and #13) could not be assigned to any factor by an automatic item selection procedure. Without these items, the scalability moved from a weak (H_i =0.37) to a medium scale (H_i =0.44). However, the item characteristic curve of the Rasch model showed a range of appropriate difficulty and the item and person parameters showed good fit (Andersen likelihood ratio test =18.40, df =11; P-value =0.07; all item values for the infit). The CSI score showed a good discriminative validity between the levels of disability of the care recipient.

CONCLUSION

The CSI questionnaire shows appropriate psychometric characteristics being a useful instrument to assess different aspects of burden in MS caregivers in clinical practice.

Correlating the Physical Activity Patterns of People with Moderate to Severe Multiple Sclerosis Disability and Their Family Caregivers

Purpose: People with multiple sclerosis (PwMS) and their family caregivers often react to the impact of the disease as an interdependent dyad. The aim of this exploratory study was to examine interdependence in the physical activity (PA) patterns of dyads affected by moderate to severe MS disability. Method: A total of 15 pairs of PwMS and their family caregivers wore accelerometers for 7 days. By collecting data simultaneously from both partners, we tested interdependence using the dyad as the unit of analysis. Results: PwMS and caregivers averaged 4,091.3 (SD 2,726.3) and 6,160.2 (SD 1,653.0) steps per day, respectively. The mean number of minutes per day of sedentary, light, and moderate to vigorous activity for PwMS was 566.3 (SD 97.7), 167.4 (SD 94.0), and 7.6 (SD 12.4), respectively, and 551.9 (SD 92.4), 199.6 (SD 63.4), and 21.4 (SD 18.2), respectively, for caregivers. Interdependence between dyads for sedentary, light, moderate to vigorous activity, and step count was low and non-significant (rs=0.20, 0.26, 0.13, and -0.27, respectively; p>0.05). Conclusions: Although our findings do not support the interdependence of PA between caregivers and care recipients with MS, they do show that both partners are not engaging in sufficient PA to achieve important health benefits. These findings are important because they indicate that the dyads are likely to benefit from interventions for changing PA behavior.

Alzheimers' disease and caregiving: a meta-analytic review comparing the mental health of primary carers to controls

OBJECTIVES

To quantitatively review the literature comparing depressed mood, anxiety and psychological distress in caregivers (CGs) of older adults with Alzheimer's disease (AD) with non-caregivers (NCGs) Methods: Eighteen independent studies comparing AD CGs (N = 2378) with NCGs (N = 70,035) were evaluated in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. Standardised mean differences (Hedges' g) with associated 95% confidence intervals and p-values were calculated using a random-effects model.

RESULTS

Studies generally conformed to STROBE criteria in terms of their methodological and procedural detail, although data management issues that may contribute to methodological bias were identified. Pooled effect estimates revealed medium to large group differences in depression (g_w = 1.01 [CI: 0.73, 1.29] p < 0.01) and anxiety (g_w = 0.64 [CI: 0.39, 0.89] p < 0.01): AD caregivers reported higher symptom severity. Gender was a significant moderator: female caregivers experienced poor self-reported mood (g_w = 1.58 [CI: 1.11, 2.05], p < 0.01), although this analysis was limited in power given the small number of contributing studies.

DISCUSSION

Caregivers of patients with AD experience poor mental health in comparison to the general population, with female caregivers being disproportionately affected. Further exploration of the psychosocial variables that contribute to these group differences is needed to inform effective support services and, in turn, help caregivers manage the emotional demands of AD.

A concerns report survey of physical activity support needs of people with moderate-to-severe MS disability and family caregivers

Purpose: To identify the most pressing needs for community resources to support physical activity participation, determinants of perceived need, and barriers to co-participation in physical activity among people with multiple sclerosis (MS) who have moderate-to-severe disability and the family caregivers providing assistance to such individuals.Methods: Seventy-eight people with MS and 46 family caregivers participated in this cross-sectional survey study, guided by the Concerns Report Methodology.Results: The results show differences between groups in rankings for some need items. However, three need items were prioritized by both people with MS and the family caregivers: (1) information about available resources to support physical activity participation, with Need Indexes of 76.6% and 52.3%, respectively; (2) programs that support joint participation of people with MS together with their caregivers in physical activity, with Need Indexes of 62.0% and 68.9%, respectively; and (3) programs that have affordable total cost of participation, with Need Indexes of 50.7% and 52.3%, respectively. A broad range of factors (i.e., education, living situation, type of community, marital status, employment, and income, as well as comorbidity status) was significantly associated with one or more of these need items. Several modifiable impairment-related, personal and logistical factors were identified by both groups as barriers to co-participation in physical activity.Conclusions: The findings highlight the complexity of developing community resources that target physical activity promotion in MS dyads. Importantly, our findings suggest that resources designed to influence dyadic physical activity participation need to include content that are responsive and tailored to both the needs of the person with MS and the unique needs of the family caregiver. The results also underscore the importance of reinforcing physical activity as a shared behavior and providing information about affordable options for exercising together to the benefit of each individual and the dyad (i.e., partnership). Overall, our findings provide a possible starting point to guide the identification of potential participants that might benefit the most from future intervention development work.Implications for rehabilitationMS has life-altering consequences for people with the disease and the family caregivers who support such individuals.Rehabilitation professionals need to reinforce physical activity as a shared behavior and provide information about affordable options for exercising together to the benefit of each individual and the dyad.A "one-size-fits-all" approach is not appropriate, therefore, clinicians need to identify flexible and pragmatic strategies to increase dyadic participation in the presence of unique caregiver and care-recipients barriers that might impede such an increase.

Does Multiple Sclerosis Affect the Inpatient Perioperative Outcomes After Total Hip Arthroplasty?

BACKGROUND

There is a paucity of studies evaluating the short-term perioperative outcomes of total hip arthroplasty (THA) in multiple sclerosis (MS) patients. Therefore, this study evaluated (1) patient factors; and (2) patient outcomes in MS THA patients compared to non-MS THA patients.

METHODS

The Nationwide Inpatient Sample from 2002 to 2013 identified 5899 MS and 2,723,652 non-MS THA patients. Yearly trends, demographics, and comorbidities were compared, and then non-MS THA patients were matched (3:1) to MS THA patients by age, gender, race, comorbidity score, and surgery year. Regression analyses compared perioperative complications (any, surgical, medical), length of stay (LOS), and discharge dispositions.

RESULTS

The annual prevalence of MS in THA patients increased from 1.36 per 1000 THAs in 2002 to 2.54 per 1000 THAs in 2013 (P = .004). MS patients were younger, more likely female, take corticosteroids, have hip osteonecrosis, and have gait abnormalities. Compared to matched cohort, MS patients had a higher risk of any surgical (odds ratio [OR] = 1.18; 95% confidence interval [95% CI], 1.02-1.37) and any medical (OR = 1.55; 95% CI, 1.34-1.81) complications, an 8.24% longer mean LOS (95% CI, 5.61-10.94; <0.0001) and were more likely to be discharged to a care facility (OR = 2.09; 95% CI, 1.82-2.40).

CONCLUSION

Orthopedic surgeons should be cognizant of the potential increased risks after THA in MS patients. Neurologists and other practitioners may help optimize and enhance the preoperative care of potential THA candidates, and provide guidance as to the appropriate timing of intervention for hip issues in MS patients.

Evaluation of a palliative and hospice care telephone hotline for patients severely affected by multiple sclerosis and their caregivers

BACKGROUND AND PURPOSE

Palliative and hospice care (PHC) still mainly focuses on patients with cancer. In order to connect patients severely affected by multiple sclerosis (MS) and caregivers to PHC, a nationwide hotline was implemented to facilitate access to PHC.

METHODS

The hotline was designed in cooperation with the German Multiple Sclerosis Society. Self-disclosed information given by callers was documented using case-report forms supplemented by personal notes. Data were analysed descriptively.

RESULTS

A total of 222 calls were documented in 27 months. The patients' mean age was 51.12 years (range 27-84 years) and mean illness duration was 18 years (range 1 month to 50 years). Inquiries included information on PHC (28.8%) and access to PHC (due to previous refusal of PHC, 5.4%), general care for MS (36.1%), adequate housing (9.0%) and emotional support in crisis (4.5%). A total of 31.1% of callers reported 'typical' palliative symptoms (e.g. pain, 88.4%), 50.5% reported symptoms evolving from MS and 35.6% reported psychosocial problems. For 67 callers (30.2%), PHC services were recommended as indicated.

CONCLUSIONS

The hotline provided insight into the needs and problems of patients severely affected by MS and their caregivers, some of which may be met by PHC. Future follow-up calls will demonstrate if the hotline helped to improve access to PHC beyond providing information. Overall, the hotline seemed to be easily accessible for patients severely affected by MS whose mobility is limited.

Daily activity level improvement with antidepressant medications predicts long-term clinical outcomes in outpatients with major depressive disorder

BACKGROUND

Major depressive disorder (MDD) significantly impacts performance of both work- and nonwork-related routine daily activities. We have shown that work productivity is significantly impaired in employed MDD patients, but the extent of impairments in nonwork-related routine activities and its association with antidepressant treatment outcomes has not been established.

MATERIALS AND METHODS

Activity impairment was measured using the sixth item of Work Productivity and Activity Impairment Scale in the Combining Medications to Enhance Depression Outcomes (CO-MED) trial (n=665). Published norms were used to define activity impairment levels. The relationship between activity impairment and baseline sociodemographic and clinical characteristics was evaluated along with changes in activity impairment and its relationship with other clinical outcomes such as symptom severity, function, and side effect burden. Remission status at 3 and 7 months was predicted based on week 6 activity impairment level.

RESULTS

Higher psychosocial and cognitive impairments and greater number of comorbid medical conditions were associated with greater activity impairment at baseline. Proportion of participants with severe activity impairment declined from 47.6% at baseline to 18.7% at 3 months, while mean activity impairment decreased from 57.1 at baseline to 32.8 at 3 months. During course of treatment, levels of activity impairment correlated most strongly with psychosocial function among measures of symptom severity, function, quality of life, and side effect burden. No or minimal activity impairment at week 6 was associated with two to three times higher rates of remission at 3 and 7 months as compared to moderate or severe activity impairment levels even after controlling for remission status at week 6 and select baseline variables.

CONCLUSION

Depressed patients have high levels of nonwork-related activity impairment at baseline that improves significantly with treatment and independently predicts long-term clinical outcomes. Brief systematic assessment of activity impairment during the course of antidepressant treatment can help inform clinical decision-making.

Under-Treatment of Patients with Moderate to Severe Psoriasis in the United States: Analysis of Medication Usage with Health Plan Data

Introduction

Psoriasis is a chronic inflammatory disorder with significant morbidity and mortality, but a persistent gap appears to exist for the adequate treatment of patients with moderate to severe disease. As the extent of under-treatment is unknown, we attempted to determine overall treatment patterns and estimate under-treatment using a large database.

Methods

Data from the US National Health and Wellness Survey was used to estimate the proportion of patients with mild, moderate or severe psoriasis. The proportion with moderate to severe disease was estimated by excluding those with mild disease, and projecting this to the total insured US population, weighted by age and gender. Using US health plan claims data, patient totals by treatment type were determined between October 1, 2007 and September 30, 2012. Patients had to be continuously enrolled in a health plan and be ≥18 years at the end of the analysis window. Psoriasis was confirmed if patients had at least one claim of any type of psoriasis except psoriatic arthropathy (ICD-9 code 696.1). A monthly treatment history, classified by biologic, traditional oral systemic, phototherapy and topical therapy, was recorded for each patient.

Results

There were an estimated 1.7 million insured US patients with moderate to severe psoriasis. Of these, 1 million (59%) were not treated for their condition in the preceding year. Among 695,488 patients who were treated for psoriasis in the preceding year, 346,201 were currently receiving treatment and 349,287 had lapsed treatment. Of the patients lapsed and currently treated in this period, the numbers who received each treatment type were 156,409 (biologic), 222,657 (traditional oral systemic), 22,911 (phototherapy), and 293,511 (topical). A limitation of the study was that only insurance claims were analyzed.

Conclusion

Moderate to severe psoriasis remains persistently untreated or under-treated. We suggest that potential barriers preventing access to care be explored.

Exploring manual handling practices by informal carers

Background/Aims:

Manual handling is a significant component in the role of an informal carer. This research aimed to understand the manual handling needs and practices of informal primary carers.

Methods:

This qualitative study utilised semi-structured face-to-face interviews to gather data from one male and female carer living in the community with a spouse with Parkinson's disease. Using comparative thematic analysis, categories and themes emerged from the detailed descriptions of the lived experiences.

Findings:

Three main themes emerged from the data: 1. Carer experience: manual handling was a daily task, however care recipients sometimes assisted in a modified environment; and carers utilised previous experiences; 2. Equipment: a variety of prescribed and non-prescribed equipment was used, however limited training was provided; 3. Perceived needs: identified needs included education on manual handling techniques, physical exercises for carers, equipment information, financial assistance for equipment and increased formal support.

Conclusions:

A lack of assistance for Australian informal carers with manual handling in relation to information provision, training and awareness of equipment and supports was highlighted. There is a need for increased carer awareness of services and support group networks, as well as for health professionals to deliver relevant advice to carers as part of service provision to care recipients.

Impact of caring for persons with Alzheimer's disease or dementia on caregivers' health outcomes: findings from a community based survey in Japan

Background

This study assessed how family caregivers for patients with Alzheimer’s disease (AD) or dementia in Japan differed from non-caregivers in characteristics and health outcomes (i.e., comorbidities, health-related quality of life [HRQoL], productivity, and resource use). Caregivers were hypothesized to experience significantly poorer outcomes than non-caregivers.

Methods

Data were combined from the 2012 and 2013 National Health and Wellness Survey in Japan (n = 60000). Caregivers for adult relatives with AD or dementia were compared with non-caregivers on: comorbidities (including Patient Health Questionnaire (PHQ-9) cutoff scores suggesting presence/absence of major depressive disorder (MDD)), Work Productivity and Activity Impairment (WPAI), SF-36v2-based HRQoL, and healthcare resource utilization. Sociodemographic characteristics, health characteristics and behaviors, and Charlson comorbidity index (CCI) scores were compared across groups. Propensity matching, based on scores generated from a logistic regression predicting caregiving, was used to match caregivers with non-caregivers with similar likelihood of being caregivers. Bivariate comparisons across matched groups served to estimate outcomes differences due to caregiving.

Results

Among 55060 respondents, compared with non-caregivers (n = 53758), caregivers (n = 1302) were older (52.6 vs. 47.5 years), more frequently female (53 % vs. 49 %), married/partnered, frequent alcohol drinkers, current smokers, exercisers, and not employed, and they averaged higher CCI scores (0.37 vs. 0.14), all p < 0.05. Propensity scores incorporated sex, age, body mass index (BMI), exercise, alcohol, smoking, marital status, CCI, insured status, education, employment, income, and children in household. A greedy matching algorithm produced 1297 exact matches, excluding 5 non-matched caregivers. Health utilities scores were significantly lower among caregivers (0.724) vs. non-caregivers (0.764), as were SF-36v2 Physical and Mental Component Summary scores. Caregivers vs. non-caregivers had significantly higher absenteeism, presenteeism-related impairment, overall work impairment (25.8 % vs. 20.4 %, respectively), and activity impairment (25.4 % vs. 21.8 %), more emergency room and traditional provider visits (7.70 vs. 5.35) in the past six months, and more frequent MDD (14 % vs. 9 %), depression, insomnia, anxiety, and pain.

Conclusions

Those providing care for patients with AD or dementia in Japan experienced significantly poorer HRQoL and greater comorbid risk, productivity impairment, and resource use. These findings inform the need for greater support for caregivers and their patients.

Alpha-1 Antitrypsin Deficiency-Associated Chronic Obstructive Pulmonary Disease: A Family Perspective

Alpha-1 antitrypsin (AAT) deficiency (AATD) is a genetic condition that can lead to the early onset of chronic obstructive pulmonary disease (COPD), a disorder that comprises elements of chronic bronchitis and emphysema. AATD is characterized by reduced levels of the AAT protease inhibitor, leading to unrestricted protease activity in the lung, which promotes destruction of lung tissue. In severe cases, patients with AATD have an increased mortality risk and, potentially, a poor quality of life due to more frequent COPD exacerbations and/or limitations on daily activity. However, the burden of AATD on members of the patient's immediate family who may serve as caregivers has not been described. Because the age range at which most patients are diagnosed with AATD may affect the economic status of an individual and/or of a family, it is likely that a diagnosis of AATD may have negative effects that extend beyond those on the diagnosed person to include immediate family members. Here, we review the literature to investigate the impact of the caregiver role of family members in disease states that affect an age group similar to AATD. Furthermore, we provide a case study showing the effect of AATD on immediate family members.

Unmet needs of caregivers of severely affected multiple sclerosis patients: A qualitative study

OBJECTIVE

Multiple sclerosis (MS) patients' caregivers are sometimes considered as "hidden patients." How much more this might be true for caregivers of severely affected MS patients has so far been scarcely studied. Palliative care also addressing relatives' needs might therefore be very relevant for these caregivers. However, we do not yet know which unmet needs they have and how these could be met. Our aim was to gain an insight into the subjectively unmet needs of caregivers of severely affected MS patients in Germany.

METHOD

The study employed a qualitative cross-sectional approach for assessing unmet needs. Twelve caregivers of severely affected MS patients were recruited using a convenience sampling approach. Face-to-face interviews were conducted, audiotaped, and transcribed verbatim, followed by qualitative content analysis.

RESULTS

Unmet needs were sorted into the following categories: "relationship to physician," "individual support by the healthcare system," "relationship to the individual severely affected by MS," "end-of-life issues," "self-care," and "higher awareness of MS." Caregivers tended to group the unmet needs of their care recipients with their own and rarely focused on their own wishes and restrictions.

SIGNIFICANCE OF RESULTS

A close patient-caregiver dyad makes it difficult to differentiate unmet caregiver needs. However, the palliative care approach might help caregivers of severely affected MS patients by answering questions on disease progress and end-of-life issues, as well as by offering respite care, support for self-care, and help in preserving one's identity, and also anticipating the time to come after the death.

Costs of formal and informal home care and quality of life for patients with multiple sclerosis in sweden

Disease progression in multiple sclerosis leads to dramatic changes in a person's ability to perform daily activities and increases reliance on external help. This study aims to describe and to estimate costs of formal/informal home care and quality of life related to multiple sclerosis. A mailed survey to a random sample of MS sufferers (n = 1500) collected data on the number of hours of home care received, type of help, productivity losses, quality of life, and disease characteristics. Costs for home care were estimated in 2012 € and factors that may influence the likelihood of getting home care were also evaluated. Formal care was given to 27% of the respondents (n = 839) at an average of 238.7 hrs/month at a mean monthly cost of €2873/person with MS. Informal care was received by 49% of the respondents at an average of 47.3 hrs/month at a mean monthly cost of €389/person with MS. Utilities across disease severity are as follows: mild MS = 0.709 (sd = 0.233), moderate MS = 0.562 (sd = 0.232), and severe MS = 0.284 (sd = 0.283). Total home care costs increased with increasing disease severity. Informal caregiving contributes significantly to MS home care in Sweden.

Quantifying the burden of informal caregiving for patients with cancer in Europe

PURPOSE

Informal caregivers for patients with cancer provide critical emotional and instrumental support, but this role can cause substantial burden. This study expands our understanding of cancer-related caregiving burden in Europe.

METHODS

Caregivers (n = 1,713) for patients with cancer and non-caregivers (n = 103,868) were identified through the 2010 and 2011 European Union National Health and Wellness Survey, administered via the Internet to adult populations in France, Germany, Italy, Spain, and the United Kingdom. Respondents completed measures of sociodemographics and health behaviors, health-related quality of life (using SF-12v2), work productivity and activity impairment (using WPAI), healthcare resource use (emergency room visits, hospitalizations, and traditional provider visits), and reported diagnosis of stress-related comorbidities (depression, anxiety, insomnia, headache, migraine, and gastrointestinal problems). Two-sided tests of means or proportions compared caregivers against non-caregivers. Multivariable regression models, comparing caregivers for patients with any cancer vs. non-caregivers on all health outcomes, adjusted for covariates (age, sex, college, income, marital status, employment, body mass index, alcohol, smoking, and Charlson comorbidity index).

RESULTS

Caregivers for patients with cancer vs. non-caregivers reported significant (P < 0.05) impairment across all health outcomes, even after adjusting for several confounds (e.g., 3.26-point lower mental health status, 0.043-point lower health utilities, 1.46 times as much work impairment, and 1.97 times the odds of anxiety).

CONCLUSIONS

Caregivers for patients with cancer experienced significant impairments. These findings reinforce the need for enhancing our understanding of the caregiving experience and developing supportive and personalized multicomponent interventions for caregivers, given their pivotal role in providing support for patients.
