What are potential barriers and enablers to patient and physician participation in Canadian cell therapy trials for stroke? A stakeholder interview study.

ABSTRACT:

Objectives

Early phase cell therapy trials face many barriers to successful, timely completion. To optimise the conduct of a planned clinical trial of mesenchymal stem cell (MSC) therapy for chronic stroke, we sought patient and physician views on possible barriers and enablers that may influence their participation.

Design

Semistructured interview study.

Setting

Patients were recruited from three rehabilitation centres in Ontario, Canada; physicians were recruited from across Canada through snowball sampling.

Participants

Thirteen chronic stroke patients (patients who had experienced a stroke at least 3 months prior; 10 male, 3 female) and 15 physicians (stroke physiatrists; 9 male, 6 female) participated in our interview study. Data adequacy was reached after 13 patient interviews and 13 physician interviews.

Methods

Interview guides and directed content analysis were based on the Theoretical Domains Framework (TDF). Interviews were coded, and relevant themes were identified.

Results

Most patients were optimistic about participating in an MSC therapy clinical trial, and many expressed interest in participating, even if it was a randomised controlled trial with the possibility of being allocated to a placebo group. However, the method of administration of cells (intravascular preferred to intracerebral) and goal of the trial (efficacy preferred to safety) may influence their intention to participate. All physicians expressed interest in screening for the trial, though many stated they were less motivated to contribute to a safety trial. Physicians also identified several time-related barriers and the need for resources to ensure feasibility.

Conclusions

This novel application of the TDF helped identify key potential barriers and enablers prior to conducting a clinical trial of MSC therapy for stroke. This will be used to refine the design and conduct of our trial. A similar approach may be adopted by other investigators considering early phase cell therapy trials.

Project description:BackgroundAudit and feedback entails systematic documentation of clinical performance based on explicit criteria or standards which is then fed back to professionals in a structured manner. There are potential significant returns on investment from partnerships between existing clinical audit programmes in coordinated programmes of research to test ways of improving the effect of their feedback to drive greater improvements in health care delivery and population outcomes. We explored barriers to and enablers of embedding audit and feedback trials within clinical audit programmes.MethodsWe purposively recruited participants with varied experience in embedded trials in audit programmes. We conducted qualitative semi-structured interviews, guided by behavioural theory, with researchers, clinical audit programme staff and health care professionals. Recorded interviews were transcribed, and data coded and thematically analysed.ResultsWe interviewed 31 participants (9 feedback researchers, 14 audit staff and 8 healthcare professionals, many having dual roles). We identified barriers and enablers for all 14 theoretical domains but no relationship between domains and participant role. We identified four optimal conditions for sustainable collaboration from the perspectives of stakeholders: resources, that is, recognition that audit programmes need to create capacity to participate in research, and research must be adapted to fit within each programme's constraints; logistics, namely, that partnerships need to address data sharing and audit quality, while securing research funding to ensure operational success; leadership, that is, enthusiastic and engaged audit programme leaders must motivate their team and engage local stakeholders; and relationships, meaning that trust between researchers and audit programmes must be established over time by identifying shared priorities and meeting each partner's needs.ConclusionSuccessfully embedding research within clinical audit programmes is likely to require compromise, logistical expertise, leadership and trusting relationships to overcome perceived risks and fully realise benefits.

Project description:Background: Diagnosis and surgical treatment decision making for breast cancers has become increasingly complex. Recently, Canadian Partnership Against Cancer (CPAC) published pan-Canadian evidence-based surgical standards for the care of breast cancer patients. This study was undertaken to assess the degree to which these standards were currently met in practice and to further understand the determinants of their implementation nationally. Methods: This study was undertaken in two parts-(1) National survey of breast cancer surgeons to assess the perceived extent of implementation of these standards in their institution and province; (2) Formation of a focus group with a representative sample of breast surgeons across Canada to further understand the barriers and facilitators towards future breast standards implementation. Results: 35 surgeons participated in the survey: 66% were from community hospitals. There were four categories of standards that were the most significantly lacking across the country-(a) processes related to quality assurance, (b) turnaround time for pathology results (c) psychosocial and health-related support for the breast cancer patient and (d) breast reconstruction for patients undergoing mastectomy. The focus group included participants from all ten Canadian provinces. For each standard, the 134 determinants fell into three main categories-individual physician (n = 27, 20%); organizational (n = 46, 34%), and system (n = 61, 46%). While specific determinants were present for each category, surgical standards were more likely to be implemented in practice if (1) they aligned with organizational priorities standards; (2) the individual physicians or physician groups were accountable to the organization and/or cancer jurisdiction regarding compliance with the standard; and (3) if infrastructure or resources existed within the organization or system for the reliable collection of relevant, meaningful, practice changing data combined with the capability of benchmarking, peer-peer comparisons and timely feedback to the surgeons. Conclusion: The results of this study demonstrated variation, barriers and opportunities for the national implementation of CPAC's breast cancer surgery standards and identified determinants of high-quality breast surgical care delivery.

Project description:BackgroundMost health systems are insufficiently prepared to promote the participation of chronically ill patients in their care. Strong primary health care (PHC) strengthens patients' resources and thus promotes their participation. The tasks of providing continuous care to people with chronic diseases and promoting self-management are the responsibility of PHC nurses. Recent research assessing enablers of or barriers to nurses' efforts to support patients' participation has mostly not considered the special situation of patients with chronic diseases or focused on the PHC setting.ObjectiveTo investigate enablers of and barriers to PHC nurses' efforts to promote the participation of chronically ill patients in their care.MethodsWe interviewed 34 practicing PHC nurses and 23 key informants with advanced knowledge of PHC nursing practice in Brazil, Germany and Spain. The data was analyzed using thematic coding.ResultsWe identified four categories of barriers and enablers. (1) Establishing bonds with patients: Interviewees emphasized that understanding patients' views and behaviours is important for PHC nurses. (2) Cooperation with relatives and families: Good relationships with families are fundamental, however conflicts within families could challenge PHC nurses efforts to strengthen participation. (3) Communication and cooperation within PHC teams: PHC nurses see Cooperative team structures as a potential enabler, while the dominance of a 'biomedical' approach to patient care is seen as a barrier. (4) Work environment: Interviewees agreed that increased workload is a barrier to patient participation.Discussion and conclusionsSupporting patient participation should be acknowledged as an important responsibility for nurses by general practitioners and PHC planners. PHC nurses should be trained in communicative competence when discussing participation with chronically ill patients. Interprofessional education could strengthen other professionals' understanding of patient participation as a nursing task.Patient or public contributionThis study is part of a research project associated with the research network 'forges: User-oriented care: Promotion of health in the context of chronic diseases and care dependency'. The study's focus and provisional results were discussed continuously with partners in health and social care practice and presented to and discussed with the public at two conferences in which patient representatives, professionals and researchers participated.
