What qualitative research can contribute to a randomized controlled trial of a complex community intervention

Community intervention to improve defibrillation before ambulance arrival in residential neighbourhoods with a high risk of out-of-hospital cardiac arrest: study protocol of a cluster-randomised trial (the CARAMBA trial)

INTRODUCTION

In Denmark, multiple national initiatives have been associated with improved bystander defibrillation and survival following out-of-hospital cardiac arrest (OHCA) in public places. However, OHCAs in residential neighbourhoods continue to have poor outcomes. The Cardiac Arrest in Residential Areas with MoBile volunteer responder Activation trial aims to improve bystander defibrillation and survival following OHCA in residential neighbourhoods with a high risk of OHCA. The intervention consists of: (1) strategically deployed automated external defibrillators accessible at all hours, (2) cardiopulmonary resuscitation (CPR) training of residents and (3) recruitment of residents for a volunteer responder programme.

METHODS AND ANALYSIS

This is a prospective, pair-matched, cluster-randomised, superiority trial with clusters of 26 residential neighbourhoods, testing the effectiveness of the intervention in a real-world setting. The areas are randomised for intervention or control. Intervention and control areas will receive the standard OHCA emergency response, including volunteer responder activation. However, targeted automated external defibrillator deployment, CPR training and volunteer responder recruitment will only be provided in the intervention areas. The primary outcome is bystander defibrillation, and the secondary outcome is 30-day survival. Data on patients who had an OHCA will be collected through the Danish Cardiac Arrest Registry.

ETHICS AND DISSEMINATION

Approval to store OHCA data has been granted from the Legal Office, Capital Region of Denmark (j.nr: 2012-58-0004, VD-2018-28, I-Suite no: 6222, and P-2021-670). In Denmark, formal approval from the ethics committee is only obtainable when the study regards testing medicine or medical equipment on humans or using genome or diagnostic imagine as data source. The Ethics Committee of the Capital Region of Denmark has evaluated the trial and waived formal approval unnecessary (H-19037170). Results will be published in peer-reviewed papers and shared with funders, stakeholders, and housing organisations through summaries and presentations.

Better health through better housing - Current impact and future prospects of randomized trials

Safe and stable housing in integrated neighborhoods with access to basic amenities and social elements is indispensable for good health. Recent randomized controlled trials have demonstrated that improvements in the built environment have positive impacts on malaria, fall injuries, and gun violence outcomes. There are several challenges associated with performing studies that assess house improvement as an intervention for advancing human health and well-being, including ethical issues, lack of blinding, spillover effects, and differential behavior. Future research is warranted to evaluate the clinical benefits and cost-effectiveness of prototype houses or energyefficient prefabricated modular homes by employing more holistic strategies, such as integration of data analytics, peer support, and whole health coaching, addition of social contextual perspectives on mobile technology-supported community-based interventions, and combination of digital technology-informed community-engaged citizen science and participatory action programs with multi-sector partnerships. Gleaning stronger evidence from clinical trials and model-based economic analyses that ascertain the effects of multiple intersecting factors on individuals and communities would illuminate effective policymaking options in healthy housing and guide successful implementation of sustainable public health policies. Straightforward and cost-effective pathways should therefore be created based on highest-quality scientific data to lead the scaling up of novel housing interventions and capacity building for health-in-all-policies to support population health equity, thereby ensuring that everyone has access to housing and the chance to live a healthy and productive life.

The clinical and cost-effectiveness of a self-management intervention for patients with persistent depressive disorder and their partners/caregivers: study protocol of a multicenter pragmatic randomized controlled trial

BACKGROUND

After regular treatment, patients with persistent depressive disorder (PDD) may remain in specialized psychiatric outpatient care without achieving remission. Lacking other options, these patients often receive long-term, non-protocolized care as usual (CAU) that does not involve the partner/caregiver of the patient. Although the revised depression treatment guidelines suggest focusing on psychiatric rehabilitation and self-management as the next treatment step for PDD, an evidence-based cost-effective self-management protocol for PDD is lacking. This study investigates the "Patient and Partner Education Program for All Chronic Illnesses" (PPEP4All) as a brief self-management protocol that could lead to lower costs, higher quality of life, and less disease burden in PDD patients and their partners/caregivers.

METHODS

Presented is the rationale and methods of a multicenter pragmatic randomized controlled trial to evaluate the clinical efficacy and cost-effectiveness of PPEP4All for patients with PDD and their partners/caregivers. In accordance with current recommendations, a mixed methods research approach is used with both quantitative and qualitative data. A total of 178 eligible outpatients with PDD and their partners/caregivers are recruited and randomized to either PPEP4All or CAU. Those assigned to PPEP4All receive nine weekly self-management sessions with a trained PPEP4All therapist. Primary and secondary outcome measurements are at 0, 3, 6, and 12 months.

DISCUSSION

This project will result in the implementation of a self-management intervention for patients with PDD, meeting an urgent need in mental healthcare. Using PPEP4All can optimize the quality and efficiency of care for both patients with PDD and their partners/caregivers.

A Comprehensive Assessment to Enable Recovery of the Homeless: The HOP-TR Study

Background: Homelessness is an increasing problem in Western European countries. In the Netherlands, policy reforms and austerity measures induced an urgent need for management information on local homeless citizens. Municipal authorities initiated cross-sectional reviews of Homeless Service (HS) users. The resulting Homeless People Treatment and Recovery (HOP-TR) study developed a health and needs assessment strategy over different domains to comprehensively assess individuals and care networks with the perspective on recovery.

Methods: Dutch HS users were selected using a naturalistic meta-snowball sampling. Semi-structured interviews provided the primary data source. The interview content was partly derived from the InterRAI Community Mental Health questionnaire and the “Homelessness Supplement.” Using the raw interview data, algorithmic summary scores were computed and integrating clinical parameters assessed. The data describe health and needs in a rights-based, recovery-oriented frame of reference. The mental health approach is transdiagnostic. The positive health framework is used for structuring health and needs aspects in relation to the symptomatic (physical and mental health), social (daily living, social participation), and personal (quality of life, meaning) dimensions of recovery.

Results: Recruitment (between 2015 and 2017) resulted in a saturated sample of 436 HS users in 16 facilities and seven cities. Most participants were long-term or intermittently homeless. The sample characteristics reveal the multi domain character of needs and the relevance of a broad, comprehensive approach. Local authorities used the reports to reflect and discuss needs, care provision, access, and network cooperation. These dialogs incited to improve the quality of care at various ecosystem levels.

Discussion: This paper describes new recruitment strategies and data collections of comprehensive data domains, to improve our knowledge in the field of homelessness. Traditional epidemiological literature on homelessness is often domain specific and relies on administrative sources. The HOP-TR study uses an analytical epidemiological approach. It shifts the assessment focus from problem-centered marginalization processes toward a comprehensive, three-dimensional recovery-oriented vision of health. Different perspectives are integrated to explore the interaction of homeless people with care networks.

Health Patterns Reveal Interdependent Needs of Dutch Homeless Service Users

Background: Homelessness is an increasing problem in Western European countries. Dutch local authorities initiated cross-sectional reviews to obtain accurate health and needs information on Homeless Service (HS) users. Methods: The Homeless People Treatment and Recovery (HOP-TR) study uses a comprehensive assessment strategy to obtain health data. Using a naturalistic meta-snowball sampling in 2015-2017, 436 Dutch HS users were assessed. The lived experience of HS users was the primary data source and was enriched with professional assessments. The InterRAI Community Mental Health questionnaire and "Homelessness Supplement" provided information in different areas of life. The approach for mental health assessments was transdiagnostic. Raw interview data were recoded to assess health and needs. The positive health framework structured symptomatic, social, and personal health domains relevant to recovery. Results: Most subjects were males, low educated, with a migration background. The majority were long-term or intermittently homeless. Concurrent health problems were present in two domains or more in most (95.0%) subjects. Almost all participants showed mental health problems (98.6%); for a significant share severe (72.5%). Frequent comorbid conditions were addiction (78%), chronic physical conditions (59.2%), and intellectual impairments (39.9%). Conclusion: The HOP-TR study reveals significant concurrent health problems among Dutch HS users. The interdependent character of different needs requires an integrated 3-D public health approach to comprehensively serve symptomatic, social, and personal dimensions, required to facilitate recovery.

Examining peer networking as a capacity-building strategy for Housing First implementation

AIMS

This study examines peer networking as a capacity-building strategy for the implementation of Housing First (HF), a complex community intervention targeting chronic homelessness.

METHODS

A qualitative, multiple case study was conducted to examine the capacity-building activities of two, multicommunity peer networks established by community leaders in the Canadian Homelessness sector. Data collection activities included document analysis, key informant interviews (n = 10), and a follow-up focus group with interview participants in each network. Thematic analyses were conducted for each network, followed by a cross-case analysis.

RESULTS

Engaging in a multicommunity peer network enhances leaders' capacity to advance HF by creating opportunities to foster trust and communication, inform continuous improvement, and navigate ambiguity. A number of contextual factors influence connections between peer networking and capacity building.

CONCLUSION

Peer networks are a valuable source of support and timely, contextually relevant knowledge for community leaders advancing local adaptation and implementation of HF.

Understanding Systems Change in Early Implementation of Housing First in Canadian Communities: An Examination of Facilitators/Barriers, Training/Technical Assistance, and Points of Leverage

We present interim findings of a cross-site case study of an initiative to expand Housing First (HF) in Canada through training and technical assistance (TTA). HF is an evidence-based practice designed to end chronic homelessness for consumers of mental health services. We draw upon concepts from implementation science and systems change theory to examine how early implementation occurs within a system. Case studies examining HF early implementation were conducted in six Canadian communities receiving HF TTA. The primary data are field notes gathered over 1.5 years and evaluations from site-specific training events (k = 5, n = 302) and regional network training events (k = 4, n = 276). We report findings related to: (a) the facilitators of and barriers to early implementation, (b) the influence of TTA on early implementation, and (c) the "levers" used to facilitate broader systems change. Systems change theory enabled us to understand how various "levers" created opportunities for change within the communities, including establishing system boundaries, understanding how systems components can function as causes of or solutions to a problem, and assessing and changing systems interactions. We conclude by arguing that systems theory adds value to existing implementation science frameworks and can be helpful in future research on the implementation of evidence-based practices such as HF which is a complex community intervention. Implications for community psychology are discussed.

The views of children and young people on the use of silk garments for the treatment of eczema: a nested qualitative study within the CLOTHing for the relief of Eczema Symptoms (CLOTHES) randomized controlled trial

Background

Many children suffer with skin diseases but to date most dermatological research has been done ‘on’ rather than ‘with’ children; in this study we actively sought the experiences of children and young people. Atopic eczema (AE) is a chronic, itchy, inflammatory skin condition that affects around 20% of children and can impact on the health and wellbeing of children and their families. The role of specialist clothing in the management of AE is poorly understood.

Objectives

The aim of this study, which was nested in a randomized controlled trial, was to qualitatively examine child participants’ experiences of using silk garments for the treatment of AE.

Methods

Eighteen children aged 5–15 years, who took part in the CLOTHing for the relief of Eczema Symptoms (CLOTHES) trial, participated in age‐appropriate individual interviews or focus groups.

Results

Thematic analysis generated four themes directly related to the silk garments: (i) expectations of the garments; (ii) wearing the garments; (iii) asking if the garments helped; and (iv) thoughts about the garments. The conclusions from this nested qualitative study are that there was some limited improvement in eczema for some children but that the hoped‐for ‘miracle cure’ did not transpire. A mixed picture of knowledge, beliefs and experiences of using the silk garments emerged.

Conclusions

Engaging children in the evaluation of the garments provided first‐hand nuanced insights that enhanced understanding of the CLOTHES study as a whole. This nested study demonstrates that children can and indeed want to be engaged in dermatological research in meaningful ways that add to our understanding of treatment options.

What's already known about this topic?

Eczema affects around 20% of children and can have a detrimental effect on the child and their family.

Adherence with topical treatments is often poor and can lead to treatment failure.

Although children are often end‐users of eczema treatments, they are rarely engaged in research involving these products beyond completing questionnaires.

What does this study add?

Children and young people can be meaningfully engaged in dermatology research and add new dimensions of understanding that would not be gained by proxy data.

Children told us about their expectations of the garments and their views once they had worn them.

The added value of child data lies in enhancing understanding of reasons for adherence and nonadherence, in facilitating interpretation of the trial results, and in ensuring selected objective outcome measures include factors important to children.

What are the clinical implications of the work?

This study illustrates the need to communicate effectively with children and young people to ascertain their thoughts and beliefs about treatment regimens and assess the likelihood of adherence.

What Happens After the Demonstration Phase? The Sustainability of Canada's At Home/Chez Soi Housing First Programs for Homeless Persons with Mental Illness

This research examined the sustainability of Canada's At Home/Chez Soi Housing First (HF) programs for homeless persons with mental illness 2 years after the end of the demonstration phase of a large (more than 2000 participants enrolled), five-site, randomized controlled trial. Qualitative interviews were conducted with 142 participants (key informants, HF staff, and persons with lived experience) to understand sustainability outcomes and factors that influenced those outcomes. Also, a self-report HF fidelity measure was completed for nine HF programs that continued after the demonstration project. A cross-site analysis was performed, using the five sites as case studies. The findings revealed that nine of the 12 HF programs (75%) were sustained, and that seven of the nine programs reported a high level of fidelity (achieving an overall score of 3.5 or higher on a 4-point scale). The sites varied in terms of the level of systems integration and expansion of HF that were achieved. Factors that promoted or impeded sustainability were observed at multiple ecological levels: broad contextual (i.e., dissemination of research evidence, the policy context), community (i.e., partnerships, the presence of HF champions), organizational (i.e., leadership, ongoing training, and technical assistance), and individual (i.e., staff turnover, changes, and capacity). The findings are discussed in terms of the implementation science literature and their implications for how evidence-based programs like HF can be sustained.

Improving access and continuity of care for homeless people: how could general practitioners effectively contribute? Results from a mixed study

OBJECTIVES

To analyse the views of general practitioners (GPs) about how they can provide care to homeless people (HP) and to explore which measures could influence their views.

DESIGN

Mixed-methods design (qualitative -> quantitative (cross-sectional observational) → qualitative). Qualitative data were collected through semistructured interviews and through questionnaires with closed questions. Quantitative data were analysed with descriptive statistical analyses on SPPS; a content analysis was applied on qualitative data.

SETTING

Primary care; views of urban GPs working in a deprived area in Marseille were explored by questionnaires and/or semistructured interview.

PARTICIPANTS

19 GPs involved in HP's healthcare were recruited for phase 1 (qualitative); for phase 2 (quantitative), 150 GPs who provide routine healthcare ('standard' GPs) were randomised, 144 met the inclusion criteria and 105 responded to the questionnaire; for phase 3 (qualitative), data were explored on 14 'standard' GPs.

RESULTS

In the quantitative phase, 79% of the 105 GPs already treated HP. Most of the difficulties they encountered while treating HP concerned social matters (mean level of perceived difficulties=3.95/5, IC 95 (3.74 to 4.17)), lack of medical information (mn=3.78/5, IC 95 (3.55 to 4.01)) patient's compliance (mn=3.67/5, IC 95 (3.45 to 3.89)), loneliness in practice (mn=3.45/5, IC 95 (3.18 to 3.72)) and time required for the doctor (mn=3.25, IC 95 (3 to 3.5)). From qualitative analysis we understood that maintaining a stable follow-up was a major condition for GPs to contribute effectively to the care of HP. Acting on health system organisation, developing a medical and psychosocial approach with closer relation with social workers and enhancing the collaboration between tailored and non-tailored programmes were also other key answers.

CONCLUSIONS

If we adapt the conditions of GPs practice, they could contribute to the improvement of HP's health. These results will enable the construction of a new model of primary care organisation aiming to improve access to healthcare for HP.

How Do Patients with Chronic Neck Pain Experience the Effects of Qigong and Exercise Therapy? A Qualitative Interview Study

Background. The high prevalence of chronic neck pain in high income countries impacts quality of life and the social and work-related activities of those afflicted. We aimed to understand how mind-body therapies and exercise therapy may influence the experience of pain among patients with chronic neck pain. Methods. This qualitative interview study investigated how patients with chronic neck pain experienced the effects of exercise or qigong therapy at two time points: during an intervention at three months and after the intervention at six months. Interviews were analysed thematically across interviews and within person-cases. Based on other qualitative studies, a sample size of 20 participants was deemed appropriate. Results. The sample (n = 20) consisted of 16 women and four men (age range: 29 to 59). Patients' experiences differed according to the therapies' philosophies. Exercise therapy group interviewees described a focus on correct posture and muscle tension release. Qigong group interviewees discussed calming and relaxing effects. Maintaining regular exercise was easier to achieve with exercise therapy. Conclusions. The findings of this study may help health care providers when counselling chronic pain patients on self-help interventions by informing them of different bodily and emotional experiences of mind-body interventions compared to exercise therapy.
