Exploring the motivations of patients with type 2 diabetes to participate in clinical trials: a qualitative analysis

摘要

Plain English SummaryPlain English SummaryCertain patient groups are reluctant to engage with clinical research and consequently findings are not always truly representative of the wider population. With the emphasis on evidence-based clinical practice, clinical research as a core activity for the National Health Service (NHS) and the rising prevalence of diabetes within the United Kingdom (UK) it is important to understand what motivates people to volunteer for research in diabetes and identify the barriers to this involvement. This research interviewed 12 people with type 2 diabetes who had previously taken part in diabetes clinical trials. The transcripts of these interviews were analysed to identify themes that informed the study findings.There were wide ranging reasons for participating in clinical trials. Both altruistic and self-interest motivation were universally expressed. The thought of helping others was a powerful experience but for some there was a sense of duty to volunteer especially if they had benefited from NHS care. Participating was empowering, with extra access to healthcare professionals, practical information and support for their condition. Coping with the logistics of being in a trial relied upon a strong network of family and friends. Some felt anxious at the end of the trial having been supported during the research and appreciating the camaraderie of belonging to a group or team.This study provides insights into the motivations and barriers to involvement in clinical research in type 2 diabetes helping researchers to encourage and support more volunteers in clinical trials. Background Certain patient groups are reluctant to engage with clinical research and consequently findings of the research are not always truly representative of the wider population. This, together with a growing prominence of evidence-based clinical practice, an increasing emphasis of clinical research as a core activity for the NHS and the rising prevalence of diabetes within the UK population, requires an understanding of motivations and barriers for patients consenting to participate in diabetes clinical trials. Methods To understand patients’ motivations for participating in clinical trials in type 2 diabetes. We conducted a qualitative study involving 12 participants with type 2 diabetes with previous involvement in clinical trials. Individual, tape-recorded, semi structured interviews were conducted to explore motivations and experiences of the participants. We carried out thematic content analysis to identify themes, from which theoretical interpretations were formed. Results There were wide ranging reasons for participating in clinical trials. We identified 3 key themes: (1) Motivations ranged from altruism to self-interest; (2) participation in clinical trials was an empowering experience; and (3) key to participation was a strong network of support. Conclusion Patients are motivated to participate in clinical trials by a sense of altruism coupled with self-interest. This self-interest centres on the belief that participation would be an informative and empowering experience with increased access to healthcare professionals. However the ability to cope with the logistics of being in clinical trials relies upon an extensive and reliable network of support from family, friends, work colleagues and employers, together with a collaborative approach to their care from the researchers and their usual healthcare providers.
