Abstract Background Chronic obstructive pulmonary disease (COPD) and muscle weakness can cause impaired physical function, significantly impacting patients’ health-related quality of life (HRQoL). Loss of muscle strength is usually assessed through clinical and performance outcome (PerfO) assessments, which consists of tasks performed in a standardized manner, providing evidence of a patient’s functional ability. However, evidence documenting the patient experience of COPD and muscle weakness is limited. Methods This two-stage qualitative study used semi-structured interviews in patients aged 45–80 years with COPD (post-bronchodilator forced expiratory volume in 1s [FEV1]/forced vital capacity ratio

Background: The participation of patients in clinical trials is crucial for the development of healthcare. There are several challenges in the recruitment of trial participants with acute medical conditions. The registry-based randomized DAPA-MI clinical trial recruited patients during hospitalization for myocardial infarction and provided study drugs in bottles with smart caps that used wireless technology to transmit monitoring data. This interview study aimed to investigate patients’ experience of participation in a clinical trial and their attitude to the new bottle cap technology. Methods: A subset of patients participating in the DAPA-MI trial were recruited from four hospitals in Sweden. Semi-structured interviews were conducted and analysed using manifest content analysis. Results: Video interviews were performed including 21 patients (four women and 17 men). The median age was 59 years (range 44–80). Four categories of patients' experiences were identified. A willingness to contribute consisted of patients’ positive attitudes to participation and to be a part of development and research. The perception of information emphasized the value of the oral information as well as the importance of time for reflection. Be in a vulnerable condition highlighted the impaired ability to perceive and remember in the acute medical condition. Adaptation to a new technology described the overall positive experiences of the smart bottle cap to evaluate adherence. Conclusions: Patients’ experiences of trial participation were in general positive but some challenges in the acute setting of a myocardial infarction were revealed. The smart bottle cap was well accepted, despite some handling difficulties.

Abstract Objectives Existing research on the perspectives of patients with cancer and health care professionals indicates that patient decision making on cancer clinical trial participation is a complex process and may be poorly understood, possibly compromising their decision to participate. This systematic review investigates interventions that support patients in their decision-making processes regarding whether to participate or not and assesses the qualities of the interventions, measures used and related outcomes. Methods Six databases were systematically searched and only studies evaluating interventions that support the decision making of adult patients offered to enter a cancer clinical trial were included. Ten articles met the criteria and were analysed using a narrative synthesis approach. Results The research focus of the included studies reflected the multifactorial nature of what constitutes support for patient decision making in terms of entering a cancer clinical trial. However, most interventions were based on the hypothesis that more information leads to support in decision making, and did not take other factors, such as the relationship to the clinical staff or relatives, the patients’ strong hope for therapeutic benefit or other existential needs into account. The interventions were primarily based on a specific tool, executed once, which seems to imply that decisions need only to be supported once and not at several time points throughout the decision process, and did not assess the importance of a patient’s family- or social relations. Moreover, few interventions focused on the patients’ counselling experience or assessed patient preferences in relation to decision making. Conclusions The findings demonstrate a lack of research on interventions to support patients’ decision making that takes other factors, apart from improving knowledge of trials, into account. Limited evidence exists on the effectiveness of decision support interventions to improve the experience of support in adult patients with cancer. Interventions that take patient preferences in relation to decision making and the social context of decision processes into account need to be developed and assessed.

The factors that influence trial participation and adherence to Tai Chi interventions in people with cardiovascular diseases remains unknown. This study aimed to explore participants’ perceptions of influential factors on their trial participation and adherence to a Tai Chi intervention within a trial setting.Patients and Methods: Participants had coronary heart disease and/or hypertension in a randomized controlled trial comparing Tai Chi with a waitlist control. Data were collected via face-to-face, semi-structured interviews and analyzed using thematic analysis.Results: Thirty-four participants from the Tai Chi group who completed the randomized trial were interviewed. Six dominating themes and four sub-themes are discussed under the facilitators of internal and external motivation, positive feelings, benefits of Tai Chi and future practice with an overall internal motivation to improve health. Positive feelings had three sub-themes: positive feelings toward Tai Chi, the project, and the learning experience. The Tai Chi instructor(s) was found to be a crucial element in motivating participants’ adherence to Tai Chi.Conclusion: From the perception of participants, the facilitators to their trial participation and adherence to a Tai Chi intervention included internal and external motivation, positive feelings towards Tai Chi, the project and the learning experience, and perceived benefits of Tai Chi. Perceived barriers included concerns about the safety and complexity of Tai Chi practice, lack of group atmosphere outside of class, and scheduling conflicts. Future researchers can address these factors to improve trial recruitment and implementation of Tai Chi and other mind-body interventions in research and for real world applications.Keywords: Tai Chi, trial participation, adherence, cardiovascular disease, interview

Abstract Background The development of new therapies may rely on the conduct of human experimentation as well as later clinical trials of therapeutic interventions. Ethical considerations seek to protect the patient from risk but few have sought to ascertain the attitude to such risk of patients with progressive debilitating or terminal conditions, for which no mitigating or curative therapies exist. Such understanding is also important if recruitment is to be maximized. We therefore sought to define the motivations for and barriers to trial participation amongst patients with progressive ataxias, as well as their condition-specific trial preferences. Methods We conducted an online survey consisting of 29 questions covering four key domains (demographics, personal motivation, drug therapy and study design) relating to the design of clinical trials. Two major ataxia charities, Ataxia UK and the Friedreich’s Ataxia Research Alliance (FARA) sent the survey to their members. Responses were analysed by disease and by ambulatory status. Results Of 342 respondents, 204 reported a diagnosis of Friedreich’s ataxia (FRDA), 55 inherited cerebellar ataxia (CA) and 70 idiopathic CA. The most important symptoms to be addressed by a trial were considered to be balance problems and ambulation, although these were superseded by speech problems in wheelchair users. Common motivations for participation were potential benefits to self and others. Reasons for non-participation included concerns about side effects, and the burden and cost of travel. Financial reimbursement for expenses was reported to be likely to increase trial engagement, Phase two trials were the most popular to participate in, and the use of a placebo arm was seen as a disincentive. Across all disease subgroups, drug repurposing trials proved popular and just under 70% of participants would be prepared to undergo intrathecal drug administration. Conclusions Knowledge of motivations for and barriers to trial participation as well as the acceptability of investigations, time commitments and routes of drug administration should inform better, more patient focused trial design. This in turn may improve recruitment and retention of participants to future trials.

Background and Objective: Clinical trials are considered to be the gold standard research methodology for evaluating the efficacy and safety of healthcare interventions. Materials and Methods: A cross-sectional study was conducted using standardized self-administered questionnaires prepared by the research team and statistician. The questionnaires were offered to cancer patients presented at a tertiary care center. Results: We surveyed 398 cancer patients, 193 (48.5%) males and 205 (51.5%) females with a mean (±standard deviation) 55.39 (±13.59) of age in years. Out of total, only 59 (14.82%) had the prior knowledge of the clinical trial. Forty-three (10.80%) participants were willing to participate in clinical trials. Conclusion: Cancer patients had preconceived notions and myths that linger in our society that clinical trial participation will harm them. The researchers/oncologists need to explore the rationale, objectives, and benefits of taking part in clinical trials and make it easy to understand by cancer patients.

Background: Ensuring adequate, informed, and timely participation in clinical trials is a multifactorial problem. We have previously developed a systematic, tailorable survey development approach that is informed by theory, can identify barriers and enablers to participation, and can suggest recruitment strategies to address these issues. In this study, we surveyed subscribers to the Canadian Breast Cancer Network (CBCN) in order to identify a comprehensive list of theory-informed barriers and enablers relevant to participation in a hypothetical breast cancer trial. Methods: We developed and conducted an online survey of breast cancer patients informed by the Theoretical Domains Framework and designed to determine previous experience with clinical trials, knowledge about clinical trials, and importance of a comprehensive list of barriers and enablers to trial participation. Participants were contacted by email or through social media. Results: From 2451 subscribers of the CBCN, we received 244 responses and 210 completed surveys (244/2451 or 9.9% participation, 210/244 or 86.1% completion). A total of 38% of respondents indicated experience in trial participation, but 83% indicated confidence in their knowledge about clinical trials. Those who had previously participated in clinical trials were more confident in their knowledge (χ2= 6.77, p = 0.009) and answered more knowledge questions (t = −3.90 p = 0.000). Endorsed barriers and enablers to participation included 39 factors across 12 of 14 domains relevant to behaviour change. Our approach identifies barriers that might be meaningfully addressed by careful knowledge provision (‘If I would learn more about my condition’; ‘If I find the trial documents hard to understand’), those that may require other theory-informed approaches to address (‘my feelings about the quality of my drug plan’; ‘my worry over unknown side effects’), and those that may require tailored approaches depending on participant differences such as previous experience in trials (‘If there were patient-friendly decision-making tools to help you make your participation decision’). Discussion: This work demonstrates that a comprehensive, theory-guided survey of barriers and enablers to participation in breast cancer clinical trials is feasible, can lead to detailed knowledge about the issues related to participation in specific trials, and most importantly, can lead to insights about evidence-based ways to better support patient participation.

Abstract Background Striae gravidarum are a common occurrence in pregnancy and many women use a topical product to prevent their development or lessen their appearance if they do develop. There is a lack of evidence on the effectiveness of many of the products used by women. This study arose from challenges in recruitment to a pilot randomised trial (ISRCTN trial registration number:76992326) designed to evaluate the feasibility of a definitive trial to compare a moisturising oil to no treatment in the prevention and reduction in severity of striae gravidarum. The study reported here explored the factors influencing recruitment to that pilot trial. Methods A qualitative descriptive study was undertaken involving primigravid women attending an Irish maternity hospital. Data were collected by semi-structured telephone interviews over a four-week period and analysed using the framework method of analysis. Fifteen interview transcripts were included in the analysis. Results Four main themes consisting of twelve categories were identified from the interview data. The themes focused on women’s prevention of stretch marks and their choice of anti-stretch mark product, who and what influenced that choice and influences on trial participation. In relation to influences on trial participation, the possibility of being randomised to the non- intervention or control group was a deterrent for many women. Conclusions The prevention of stretch marks is important to pregnant women, as is their choice of product to prevent them. Offering women the opportunity to be part of a trial that would be of low burden and would test a well-known product may optimise recruitment. However, reluctance to be randomised because of the possibility of being allocated to the non-intervention control group suggests that further work is needed in this field on how best to communicate uncertainty to potential participants.

Abstract Background Participation in randomized controlled trials (RCTs) may be quite demanding and could represent an important burden for patients. We aimed to explore this research burden (i.e., the psychological, physical, and financial burdens) experienced by patients through their participation in a RCT. Methods We conducted a systematic review of qualitative studies exploring adult patients’ experiences with RCT participation. We searched MEDLINE (PubMed), CINAHL, PSYCHINFO, and Embase (search date March 2018) for eligible reports. Qualitative data coding and indexing were assisted by NVivo. The quality of reports was assessed by using the Critical Appraisal Skills Program (CASP) tool. Results We included 45 qualitative studies that involved 1732 RCT participants. Important psychological burdens were identified at every stage of the trial process. Participants reported feeling anxiety and being afraid of “being a ‘guinea pig’” and described undergoing randomization and allocation to a placebo as particularly difficult resulting in disappointment, anger, and depression. Patients’ follow-up and trial closure were also responsible for a wide range of psychological, physical, and financial burdens. Furthermore, factors related to burdensome impacts and consequences were discerned. These factors involved trial information, poorly organized and too-demanding follow-up, and lack of appropriate management when the patient’s participation ended. Trial participation was also associated with beneficial effects such as the satisfaction of feeling “useful,” gaining “a sense of control,” and receiving special attention. Conclusions Our finding provides a detailed description of research burden across the whole RCT process. Many of the burdens described could be anticipated, and some avoided in a movement toward minimally disruptive clinical research. Such an approach could improve trial recruitment and retention.

ABSTRACT (198): Background: The multi-dose regimen is a known barrier to successful human papillomavirus (HPV) vaccination. Emerging evidence suggests that one vaccine dose could protect against HPV. While there are clear advantages to a single dose schedule, beliefs about vaccine dosage in low and middle income countries (LMICs) are poorly understood. We investigated acceptability of dose-reduction among girls, and parents/guardians of girls, randomised to receive one, two or three doses in an HPV vaccine dose-reduction and immunobridging study (DoRIS trial) in Tanzania. Methods: Semi-structured interviews with girls (n = 19), and parents/guardians of girls (n = 18), enrolled in the study and completing their vaccine course. Results: Most participants said they entrusted decisions about the number of HPV vaccine doses to experts. Random allocation to the different dose groups did not feature highly in the decision to participate in the trial. Given a hypothetical choice, girls generally said they would prefer fewer doses in order to avoid the pain of injections. Parental views were mixed, with most wanting whichever dose was most efficacious. Nonetheless, a few parents equated a higher number of doses with greater protection. Conclusion: Vaccine trials and programmes will need to employ careful messaging to explain that one dose offers sufficient protection against HPV should emerging evidence from ongoing dose-reduction clinical trials support this.

Abstract Background While a growing body of research has explored why people take part in clinical trials, this research has not considered how people’s understandings, motivations and agendas might influence their conduct during a trial. This is an important area of enquiry because it is now widely recognised that an intervention might lead to different clinical outcomes when delivered as part of a trial than when implemented in routine clinical practice; however, the reasons for this are not fully understood. Methods/design We interviewed 24 individuals who took part in a trial of an innovative health technology under development for people with type 1 diabetes which automatically regulates blood glucose: the closed-loop system. Participants were interviewed following randomisation to a closed-loop and at trial closeout. Results Participants provided complex agendas for taking part in which altruistic and self-interested considerations were often inseparable. Many described belonging to a wider diabetes community and being beneficiaries of others’ participation in research and how this had given rise to attendant citizenship obligations. Participants also shared the excitement and pride they experienced from contributing to research which situated them at the forefront of technological innovation and enabled them to present themselves to others, by virtue of their trial participation, as ambassadors of hope and research pioneers. Given their desire to support the progression of a potentially life-changing technology, and be part of that innovation, participants, at follow-up, described having made extra effort during the trial. Specifically, participants described having been more focused on their diabetes management to help create conditions in which the closed-loop could work most effectively to optimize their blood glucose control. Conclusions Our findings contribute a new dimension to understandings of trial effects; specifically, we argue that, to aid interpretation of trial outcomes, participants’ understandings and motivations for participation need to be considered. We highlight the potential pertinence of our findings in the contemporary era of bio-citizenship where, increasingly, people are driving research agendas and see themselves as co-producers of knowledge. We also recommend a new concept be introduced into the literature—‘the altruselfish agenda’—to recognise potential inseparability of self-interested and altruistic motivations.

Background: Family members, or others, often assume the role of informal (unpaid) carers of people with chronic illnesses. Care-giving, however, can impact profoundly on the quality of life of carers and can cause carer worry, stress and guilt. Implementing interventions that positively affect the lives of carers is important; however, carers as a group are often difficult to reach. We embedded a study within a pilot-feasibility trial of a mindfulness based intervention to determine and prioritise the key motivators and challenges influencing informal carers’ decisions for participating in a trial. Methods: We used a multi-method approach involving interviews with participants from a ‘host trial’ and data from systematic reviews to develop a survey that was distributed to informal carers in Ireland. The survey consisted of 28 motivator and 17 challenge statements. Participants rated how important they thought each statement was when deciding to take part in a trial on a 5-point Likert Scale. Mean scores and standard deviations were calculated for each statement and arranged in descending order to provide the priority lists. Results: Thirty-six carers responded to the survey. Helping to create awareness about carers was the top ranked motivator, followed by four study design statements related to the time at which the study occurs, the study location, format of delivery and venue. The least important motivator related to how carers were invited to take part in a study. Difficulties in planning due to the caring role emerged as the most important challenge, followed by being unable to leave the care recipient on his/her own. Conclusions: Insight into decision-making for research participation will assist trial developers tailor trial processes for informal carer populations. We recommend that trialists should consider these motivators and challenges when designing future trials involving informal carers so as to enhance trial feasibility and success.

Objectives: We aimed to investigate the motives, barriers and experiences of HIV-STAR study participants. The HIV-STAR study was an analytical HIV treatment interruption trial (ATI) aiming to evaluate the origin of viral rebound, conducted in Ghent, Belgium. Methods: A mixed-method study was performed among 11 participants of the HIV-STAR study. Two self-administered questionnaires with 32 and 23 items, respectively, assessed motives, barriers and experiences of the research participants. In-depth interviews were conducted to further explore and understand topics that had emerged from these surveys. Results: Motives of ATI study participants were primarily related to the improvement of their own health perspectives and to their contribution to find an HIV cure. Barriers for ATI participation mostly related to practical issues, such as difficulty in planning study visits. Ten out of 11 participants reported a very high overall satisfaction and were willing to participate in another ATI. This satisfaction was predominantly linked to clear communication and guidance. Invasive sampling during the ATI was less of a burden than anticipated by participants. However, most participants underestimated the emotional impact of HIV treatment interruption, which was associated with feelings of uncertainty and loss of control. Risk of HIV transmission because of viral rebound was also mentioned as burdensome during this phase. Conclusions: Involvement in an ATI was positively evaluated by HIV-STAR participants. Contributing to HIV cure research outweighed the burden of study participation for most participants. The latter aspects were attenuated by mutual decision making and the experience of empathy from the research team. Still, issues regarding privacy and the psychosocial impact of treatment interruption, including sexuality and HIV transmissibility, should be addressed in a better way.

Abstract Background Randomised controlled trials are widely established as the best method for testing health interventions whilst minimising bias. However, recruitment and subsequent retention of children and adolescents in healthcare trials is challenging. Participant information sheets are often lengthy and difficult to read and understand. Presenting key information using multimedia may help to overcome these limitations and better support young people and their parents in deciding whether to participate in a clinical trial. Methods The TRECA (TRials Engagement in Children and Adolescents) study has two phases. The first phase involves a qualitative study with children and adolescents and their parents to inform the development of multimedia information resources and iterative user testing to refine the resources. The second phase will embed the use of the multimedia information resources into six host trials in the United Kingdom. Patients and parents approached to participate in the host trials will be randomly allocated to either use the multimedia information resource in conjunction with standard participant information sheets, the multimedia information resource alone, or the standard participant information sheets alone. The primary outcome will be the effect of the multimedia information resources on recruitment into trials. Other outcomes measured include the effect of multimedia information resources on retention of participants into the host trials and the impact on family members’ decision-making processes, when compared to standard participant information sheets alone. Discussion This study will inform whether multimedia information resources, when developed using participatory design principles, are able to increase recruitment and retention of children and adolescents into trials. There is also the potential for patients to make better informed decisions through the use of multimedia information resources. The multimedia information resources also have the potential to assist with providing information on other healthcare decisions outside of clinical trials.

Background and objectives: Inadequate minority participation in clinical research can threaten the applicability and strength of scientific findings. Previous research suggests that trial participation rates are lowest among Asian Americans, compared to other groups. This study explored barriers to clinical research participation among elder Chinese living in Houston, Texas. Additionally we administered the Trust in Medical Researchers Scale (TIMRS), used previously in researching trust in medical researchers as related to research participation. Design: In this mixed methods study, a semi-structured interview, including the TIMRS were administered to 30 adults of Chinese ancestry aged 50 years or older recruited from a Chinese community center. Interviews were conducted in English, Mandarin and Cantonese and independently coded and analyzed using thematic content analysis. TIMRS scores were calculated for participants. Results: Participants were 70% female, 70% were 60 or elder, all were foreign born and on average lived in the US for 21.8 years. Participants perceived risks to research participation and preferred language concordant research staff. Interviewees were more willing to participate if they perceived personal and community health-related benefits. The overall TIMRS score was 23.9 (±5.0), lower than the overall TIMRS for Whites in a previous study (P

Background: Insufficient patient recruitment can impair the conduct of clinical trials substantially, not least because a significant number of eligible patients decline trial participation. Though barriers and motivational factors have been worked out for patients with cancer or chronic diseases, little is known about primary care patients’ perceptions towards trial participation when visiting their family practitioner (FP) with acute uncomplicated conditions. This study aims to assess primary care patients’ motivation and barriers to participate in trials, and to identify factors that optimize patient recruitment in future trials.Methods: This study was embedded in a drug trial comparing two treatment strategies for women with uncomplicated urinary tract infection in primary care. Semi-structured telephone interviews both with trial participants and decliners were conducted. The interview guideline focused on patients’ personal motivational or hampering factors. Further topics were study theme, FPs’ role, randomization, trial procedures, and potential motivational factors or barriers presumed to be relevant for other patients. Transcripts were analyzed by summarizing content analysis.Results: 20 interviews with trial participants and 5 interviews with trial decliners were conducted. Results show various reasons for trial participation from three categories: personal aspects, trial related aspects and patient-physician-relationship. A relevant trial topic and perceived personal benefit promotes participation as well as the wish to support research in general. Additionally, a maximum of safety concerning symptom relief reassures patients significantly. Trust in the FP plays also an important role in the decision process. Trial decliners show strong individual treatment preferences, which, together with individual reasons, lead to trial refusals.Conclusions: To optimize recruitment conditions for further clinical trials on acute and common conditions in family medicine, the following key issues should be considered: emphasizing patients’ personal benefit, featuring patient relevant trial topics, providing a maximum of safety, keeping effort by trial procedures comfortable.

Abstract Background A special challenge for research studies of breast cancer among females is low patient participation rates. We compiled this systematic review to identify reasons why women with, or at high risk of, breast cancer do or do not participate in medicinal studies of breast cancer. Method A systematic literature search in the databases Cochrane Library, EMBASE, Medline, Pascal Biomed, ACP Journal Club and CINAHL, as well as searches through reference lists of relevant texts, was performed. Results Of 39 relevant full texts, ultimately, nine studies (1 qualitative, 8 quantitative) were included after applying the inclusion criteria. Despite a lack of data material, it was possible to identify various factors influencing women's willingness to participate in medicinal studies and group them into three categories: person-related, study-related, and physician-related. Conclusion Reasons for or against participation in studies of medicinal therapies by women with, or at high risk of, breast cancer are multi-dimensional, and should be considered when planning such studies to garner higher participation rates. For a more comprehensive picture of factors that affect participation, further studies in this field are recommended.
