Randomized controlled trial of an internet-based self-guided hand exercise program to improve hand function in people with systemic sclerosis: the Scleroderma Patient-centered Intervention Network Hand Exercise Program (SPIN-HAND) trial

BACKGROUND

Systemic sclerosis (scleroderma; SSc) is a rare autoimmune connective tissue disease. Functional impairment of hands is common. The Scleroderma Patient-centered Intervention Network (SPIN)-HAND trial compared effects of offering access to an online self-guided hand exercise program to usual care on hand function (primary) and functional health outcomes (secondary) in people with SSc with at least mild hand function limitations.

METHODS

The pragmatic, two-arm, parallel-group cohort multiple randomized controlled trial was embedded in the SPIN Cohort. Cohort participants with Cochin Hand Function Scale (CHFS) scores ≥ 3 and who indicated interest in using the SPIN-HAND Program were randomized (3:2 ratio) to an offer of program access or to usual care (targeted N = 586). The SPIN-HAND program consists of 4 modules that address (1) thumb flexibility and strength; (2) finger bending; (3) finger extension; and (4) wrist flexibility and strength. The primary outcome analysis compared CHFS scores 3 months post-randomization between participants offered versus not offered the program. Secondary outcomes were CHFS scores 6 months post-randomization and functional health outcomes (Patient-Reported Outcomes Measurement Information System profile version 2.0 domain scores) 3 and 6 months post-randomization.

RESULTS

In total, 466 participants were randomized to intervention offer (N = 280) or usual care (N = 186). Of 280 participants offered the intervention, 170 (61%) consented to access the program. Of these, 117 (69%) viewed at least one hand exercise instruction video and 77 (45%) logged into the program website at least 3 times. In intent-to-treat analyses, CHFS scores were 1.2 points lower (95% CI - 2.8 to 0.3) for intervention compared to usual care 3 months post-randomization and 0.1 points lower (95% CI - 1.8 to 1.6 points) 6 months post-randomization. There were no statistically significant differences in other outcomes.

CONCLUSION

The offer to use the SPIN-HAND Program did not improve hand function. Low offer uptake, program access, and minimal usage among those who accessed the program limited our ability to determine if using the program would improve function. To improve engagement, the program could be tested in a group format or as a resource to support care provided by a physical or occupational therapist.

Intensity of care and perceived burden among informal caregivers to persons with chronic medical conditions: a systematic review and meta-analysis

PURPOSE

Informal caregivers provide ongoing assistance to a loved one with a health condition. No studies have compared caregiving intensity and perception of burden across chronic medical conditions.

MATERIALS AND METHODS

Databases were searched from inception through 11 September 2020 to identify studies that included the Level of Care Index or the Zarit Burden Inventory (ZBI) among caregivers for people with chronic diseases. Pooled mean ZBI scores and 95% confidence intervals by medical condition were calculated using a random effects model and heterogeneity with I².

RESULTS

Ninety-seven included articles reported on 98 unique samples across 21 chronic diseases. No study used the Level of Care Index. Among 12 disease groups with more than one study, heterogeneity was too high (I² range: 0-99.6%, ≥76.5% in 11 groups) to confidently estimate burden. The percent of studies rated high risk of bias ranged from 0% to 98%, but all external validity items were rated as high-risk in >50% of studies.

CONCLUSIONS

Findings highlight the need for studies on caregiver burden to improve sampling techniques; better report sampling procedures and caregiver and care recipient characteristics; and develop a standard set of outcomes, including a measure of caregiving intensity. Systematic Review Registration: CRD42017080962IMPLICATIONS FOR REHABILITATIONThe amount of burden reported by caregivers to loved ones is associated with reduced physical and mental health.We found considerable heterogeneity in perceived burden reported by informal caregivers across different studies within disease groups, which is likely related to methodological issues, including sampling techniques.Health care providers who use research on caregiver burden should assess how representative study samples may be and exercise caution in drawing conclusions.

Effects of non-pharmacological and non-surgical interventions on health outcomes in systemic sclerosis: protocol for a living systematic review

INTRODUCTION

Systemic sclerosis (SSc; scleroderma) is a rare, chronic, autoimmune disease with a high level of burden, a significant impact on the ability to carry out daily activities, and a considerable negative impact on health-related quality of life. Non-pharmacological interventions could be provided to potentially improve mental and physical health outcomes. However, the effectiveness of non-pharmacological interventions on health and well-being among individuals with SSc has not been well established. The proposed living systematic review aims to identify and evaluate randomised controlled trial (RCT) evidence on the effectiveness of non-pharmacological and non-surgical interventions on mental and physical health outcomes and on the delivery of such services in SSc.

METHODS AND ANALYSIS

Eligible studies will be RCTs that examine non-pharmacological and non-surgical interventions aimed at improving health outcomes among individuals with SSc or the delivery of services intended to improve healthcare or support of people with SSc (eg, support groups). All RCTs included in a previous systematic review that sought studies published between 1990 and March 2014 will be evaluated for inclusion. Additional trials will be sought from January 2014 onwards using a similar, augmented search strategy developed by a health sciences librarian. We will search the MEDLINE, Embase, CINAHL, PsycINFO, Cochrane Library and Web of Science databases and will not restrict by language. Two independent reviewers will determine the eligibility of identified RCTs and will extract data using a prespecified standardised form in DistillerSR. Meta-analyses will be considered if ≥2 eligible RCTs report similar non-pharmacological interventions and comparable health outcomes. We will conduct a qualitative synthesis for interventions that cannot be synthesised via meta-analysis.

ETHICS AND DISSEMINATION

We will post initial and ongoing results via a website, publish results periodically via peer-reviewed journal publication, and present results at patient-oriented events.

Effects of cosmetic and other camouflage interventions on appearance-related and psychological outcomes among adults with visible differences in appearance: a systematic review

OBJECTIVE

Visible differences in appearance are associated with poor social and psychological outcomes. Effectiveness of non-surgical cosmetic and other camouflage interventions is poorly understood. The objective was to evaluate effects of cosmetic and other camouflage interventions on appearance-related outcomes, general psychological outcomes and adverse effects for adults with visible appearance differences.

DESIGN

Systematic review.

DATA SOURCES

MEDLINE (Ovid), EMBASE (Ovid), PsycINFO (Ovid) CINAHL and Cochrane Central databases searched from inception to 24 October 2020. Two reviewers independently reviewed titles and abstracts and full texts.

ELIGIBILITY CRITERIA

Randomised controlled trials in any language on non-surgical cosmetic or other camouflage interventions that reported appearance-related outcomes, general psychological outcomes or adverse effects for adults with visible appearance differences.

DATA EXTRACTION AND SYNTHESIS

Two reviewers independently extracted data, assessed intervention reporting using the Template for Intervention Description and Replication checklist, and assessed risk of bias using the Cochrane risk of bias tool. Outcomes included appearance-related outcomes, general psychological outcomes (eg, depression, anxiety) and adverse effects.

RESULTS

One head-to-head trial and five trials with waiting list or routine care comparators were included. All had unclear or high risk of bias in at least five of seven domains. Effect sizes could not be determined for most outcomes due to poor reporting. Between-group statistically significant differences were not reported for any appearance-related outcomes and for only 5 of 25 (20%) other psychological outcomes. Given heterogeneity of populations and interventions, poor reporting and high risk of bias, quantitative synthesis was not possible.

CONCLUSIONS

Conclusions about effectiveness of non-surgical cosmetic or other camouflage interventions could not be drawn. Well-designed and conducted trials are needed. Without such evidence, clinicians or other qualified individuals should engage with patients interested in cosmetic interventions in shared decision making, outlining potential benefits and harms, and the lack of evidence to inform decisions.

Factors associated with fears due to COVID-19: A Scleroderma Patient-centered Intervention Network (SPIN) COVID-19 cohort study

INTRODUCTION

No studies have examined factors associated with fear in any group of people vulnerable during COVID-19 due to pre-existing medical conditions.

OBJECTIVE

To investigate factors associated with fear of consequences of COVID-19 among people living with a pre-existing medical condition, the autoimmune disease systemic sclerosis (SSc; scleroderma), including country.

METHODS

Pre-COVID-19 data from the Scleroderma Patient-centered Intervention Network (SPIN) Cohort were linked to COVID-19 data collected in April 2020. Multivariable linear regression was used to assess factors associated with continuous scores of the 10-item COVID-19 Fears Questionnaire for Chronic Medical Conditions, controlling for pre-COVID-19 anxiety symptoms.

RESULTS

Compared to France (N = 156), COVID-19 Fear scores among participants from the United Kingdom (N = 50) were 0.12 SD (95% CI 0.03 to 0.21) higher; scores for Canada (N = 97) and the United States (N = 128) were higher, but not statistically significant. Greater interference of breathing problems was associated with higher fears due to COVID-19 (Standardized regression coefficient = 0.12, 95% CI 0.01 to 0.23). Participants with higher financial resources adequacy scores had lower COVID-19 Fear scores (Standardized coefficient = -0.18, 95% CI -0.28 to -0.09).

CONCLUSIONS

Fears due to COVID-19 were associated with clinical and functional vulnerabilities in this chronically ill population. This suggests that interventions may benefit from addressing specific clinical issues that apply to specific populations. Financial resources, health policies and political influences may also be important. The needs of people living with chronic illness during a pandemic may differ depending on the social and political context in which they live.

Protocol for a partially nested randomised controlled trial to evaluate the effectiveness of the scleroderma patient-centered intervention network COVID-19 home-isolation activities together (SPIN-CHAT) program to reduce anxiety among at-risk scleroderma patients

OBJECTIVE

Contagious disease outbreaks and related restrictions can lead to negative psychological outcomes, particularly in vulnerable populations at risk due to pre-existing medical conditions. No randomised controlled trials (RCTs) have tested interventions to reduce mental health consequences of contagious disease outbreaks. The primary objective of the Scleroderma Patient-centered Intervention Network COVID-19 Home-isolation Activities Together (SPIN-CHAT) Trial is to evaluate the effect of a videoconference-based program on symptoms of anxiety. Secondary objectives include evaluating effects on symptoms of depression, stress, loneliness, boredom, physical activity, and social interaction.

METHODS

The SPIN-CHAT Trial is a pragmatic RCT that will be conducted using the SPIN-COVID-19 Cohort, a sub-cohort of the SPIN Cohort. Eligible participants will be SPIN-COVID-19 Cohort participants without a positive COVID-19 test, with at least mild anxiety (PROMIS Anxiety 4a v1.0 T-score ≥ 55), not working from home, and not receiving current counselling or psychotherapy. We will randomly assign 162 participants to intervention groups of 7 to 10 participants each or waitlist control. We will use a partially nested RCT design to reflect dependence between individuals in training groups but not in the waitlist control. The SPIN-CHAT Program includes activity engagement, education on strategies to support mental health, and mutual participant support. Intervention participants will receive the 4-week (3 sessions per week) SPIN-CHAT Program via videoconference. The primary outcome is PROMIS Anxiety 4a score immediately post-intervention.

ETHICS AND DISSEMINATION

The SPIN-CHAT Trial will test whether a brief videoconference-based intervention will improve mental health outcomes among at-risk individuals during contagious disease outbreak.

Reporting of drug trial funding sources and author financial conflicts of interest in Cochrane and non-Cochrane meta-analyses: a cross-sectional study

OBJECTIVE

To (1) investigate the extent to which recently published meta-analyses report trial funding, author-industry financial ties and author-industry employment from included randomised controlled trials (RCTs), comparing Cochrane and non-Cochrane meta-analyses; (2) examine characteristics of meta-analyses independently associated with reporting funding sources of included RCTs; and (3) compare reporting among recently published Cochrane meta-analyses to Cochrane reviews published in 2010.

DESIGN

Review of consecutive sample of recently published meta-analyses.

DATA SOURCES

MEDLINE database via PubMed searched on 19 October 2018.

ELIGIBILITY CRITERIA FOR SELECTING ARTICLES

We selected the 250 most recent meta-analyses listed in PubMed that included a documented search of at least one database, statistically combined results from ≥2 RCTs and evaluated the effects of a drug or class of drugs.

RESULTS

90 of 107 (84%) Cochrane meta-analyses reported funding sources for some or all included trials compared with 21 of 143 (15%) non-Cochrane meta-analyses, a difference of 69% (95% CI 59% to 77%). Percent reporting was also higher for Cochrane meta-analyses compared with non-Cochrane meta-analyses for trial author-industry financial ties (44% versus 1%; 95% CI for difference 33% to 52%) and employment (17% versus 1%; 95% CI for difference 9% to 24%). In multivariable analysis, compared with Cochrane meta-analyses, the odds ratio (OR) for reporting trial funding was ≤0.11 for all other journal category and impact factor combinations. Compared with Cochrane reviews from 2010, reporting of funding sources of included RCTs among recently published Cochrane meta-analyses improved by 54% (95% CI 42% to 63%), and reporting of trial author-industry financial ties and employment improved by 37% (95% CI 26% to 47%) and 10% (95% CI 2% to 19%).

CONCLUSIONS

Reporting of trial funding sources, trial author-industry financial ties and trial author-industry employment in Cochrane meta-analyses has improved since 2010 and is higher than in non-Cochrane meta-analyses.

Reasons for not participating in scleroderma patient support groups: a comparison of results from the North American and European scleroderma support group surveys

PURPOSE

Many people with scleroderma rely on peer-led support groups as a coping resource. Reasons for not attending support groups in scleroderma have been investigated only in North American participants. This study assesses reasons for nonattendance in European countries and compares results with previously published North American findings.

MATERIALS AND METHODS

The same 21-item survey as used in the North American sample assessed possible reasons for not attending scleroderma support groups. Proportions of items rated Important or Very Important were compared between samples.

RESULTS

Consistent with the North American survey findings (N = 242), the two items most commonly rated as (Very) Important reasons for nonattendance among 228 European participants were (1) already having enough support (57%), and (2) not knowing of any local scleroderma support groups (58%). Compared to North American non-attenders, European patients were significantly more likely to rate not knowing enough about what happens at support groups (46% vs 19%), not having reliable ways to get to meetings (35% vs 17%), and being uncomfortable sharing experiences with a group (22% vs 11%) as (Very) Important reasons for nonattendance.

CONCLUSIONS

Improving access to European support groups, providing education about support groups and group leader training may encourage participation.IMPLICATIONS FOR REHABILITATIONRehabilitation professionals might help develop local support groups for people with systemic sclerosis (scleroderma) to address the lack of access to these groups for many patients.The need for transportation and limited local accessibility may also be addressed by implementing online systemic sclerosis support groups.Professionals in the field of rehabilitation may work with people with systemic sclerosis and patient organizations to provide education about support groups to improve support group attendance in Europe.

The Scleroderma Research Topics Survey for patients and health care professionals: A Scleroderma Patient-centered Intervention Network Project

Involving patients and health care professionals in research has been shown to be a useful strategy to generate program development ideas and establish research priorities. Online surveys can be used to identify patient research priorities. The Scleroderma Patient-centered Intervention Network is an international collaboration dedicated to researching problems important to people with scleroderma and developing, testing, and disseminating educational, self-management, rehabilitation, and psychological tools to support coping within the disease. The objectives of the Scleroderma Patient-centered Intervention Network Scleroderma Research Topics Survey were to (1) obtain input on online programs that Scleroderma Patient-centered Intervention Network could develop, (2) identify research topics important to members of the scleroderma community that could be addressed via the Scleroderma Patient-centered Intervention Network Cohort, and (3) identify potentially understudied groups. Eligible survey respondents included individuals with scleroderma and their caregivers, health care professionals, and patient organization representatives. Responses were evaluated separately for online programs, possible research questions, and understudied groups. In each category, thematic analysis was used to group responses into themes. A total of 125 participants (100 patients, 24 health care professionals, and 1 caregiver) completed the survey, and responses from patients and health care professionals were reported. For online programs, frequent recommendations included Interactive Platforms to facilitate communication between patients, as well as interventions targeting physical activity, and emotions and stress. Common responses for possible research questions were related to calcinosis, accessing health care, and quality of life. The most common suggestions for understudied groups were young patients, minority patients, and patients with calcinosis. Research topic suggestions provided in the survey will inform Scleroderma Patient-centered Intervention Network priorities and can be considered by other researchers.

Effects of training and support programs for leaders of illness-based support groups: commentary and updated evidence

BACKGROUND

Peer-led support groups play an important role in supporting people with chronic diseases. They may be particularly important for people with rare diseases who typically do not have access to professional support options that focus on their disease-specific needs. Many peer-led support groups in rare diseases, however, are not sustained, and many patients do not have access to support groups. Training and education for peer support group leaders could address barriers to initiating and sustaining groups, but there is little evidence on the effectiveness of support group leader training programs. A previous systematic review evaluated the effects of training programs for peer leaders of support groups for people with medical illness on leader and support group outcomes, but it identified only one randomized controlled trial (RCT) that compared high- and low-resource training programs for cancer support group leaders. The trial did not find evidence that the high-resource program was more effective, but was limited by a small sample size and serious methodological limitations. To meet the needs of people living with the rare autoimmune connective tissue disease scleroderma, the Scleroderma Patient-centered Intervention Network has partnered with patient organizations to develop the Scleroderma Support group Leader EDucation Program, and a full-scale RCT to test the effectiveness of the program is planned. To verify the need for such a trial, we updated the previous systematic review.

UPDATED EVIDENCE

Review methods for the update were unchanged from the initial review. The updated database search yielded 1504 unique citations in addition to the 9757 assessed for eligibility in the previous review. All additional citations identified in the updated search were excluded at the title and abstract review stage.

CONCLUSIONS

Our systematic review update found that there is presently insufficient evidence on the effectiveness of training and support programs for peer leaders of disease-based support groups, highlighting the need for well-designed and rigorously conducted RCTs to examine the effects of training for peer leaders of support groups, especially in a rare disease context. The Scleroderma Patient-centered Intervention Network's trial of the Scleroderma Support group Leader EDucation Program will serve as such a trial.

Challenges and support service preferences of informal caregivers of people with systemic sclerosis: a cross-sectional survey

Purpose: To evaluate the importance of different challenges experienced by informal caregivers to persons with systemic sclerosis (SSc) and identify priorities for support services that could be developed.Materials and Methods: Caregivers of people with SSc from three continents completed an online questionnaire to rate the importance of possible caregiver challenges and likelihood of using different forms of support services. Importance of challenges and likelihood of using support services were rated from 1 (not important; not likely to use) to 4 (very important; very likely to use).Results: Two hundred and two informal caregivers completed the survey (79 women, 123 men). Mean age was 58 years (standard deviation = 13). The most important challenges were related to supporting the care recipient with emotional difficulties and physical discomfort. Caregivers indicated that they would be more likely to use support services that involved online or hard-copy information resources, including those provided soon after diagnosis, compared to support that involved interacting with others.Conclusions: Supporting the care recipient in managing emotional difficulties and physical discomfort were important challenges among caregivers. Interventions delivered through hardcopy or online resources, including those delivered soon after the care recipient's diagnosis, were rated as being most likely to be used by caregivers.Implications for rehabilitationMany caregivers for individuals with systemic sclerosis report struggling to support their care recipient with emotional difficulties and physical discomfort.Rehabilitation professionals can aid in the development of support services that caregivers have identified as being likely to use and can refer caregivers to resources that they have identified as being helpful, such as educational information about the disease.The development of support services should focus on aspects of caring that caregivers found most challenging and be delivered in a format that considers caregiver preferences.
