Abstract
BACKGROUND Successful achievement of randomized controlled trials (RCTs) is dependent on the acquisition of informed consent (IC) from patients. The aim of this study was to prospectively calculate the proportion of participation in a surgical RCT and to identify the reasons for failed acquisition of IC. METHODS A 50-insitution RCT was conducted to evaluate oncological outcomes of open and laparoscopic surgery for stage IV colon cancer (JCOG1107: UMIN-CTR 000000105). The success rate of obtaining IC was evaluated in eight periods between January 2013 and January 2021. In addition, reasons for failed acquisition of IC were identified from questionnaires. RESULTS In total, 391 patients were informed of their eligibility for the trial, and 168 (42%) were randomly assigned to either the laparoscopic surgery group (n = 84) or open surgery group (n = 84). The success rate of IC acquisition ranged from 33 to 58% in three periods. The most common reasons for failed IC acquisition were the patients' preference for one approach of surgery based on recommendations from referring doctors and family members, and anxiety/unhappiness about randomization. CONCLUSIONS The success rate of acquiring IC from patients for an RCT of laparoscopic versus open surgery for stage IV colon cancer was lower than the expected rate planned in the protocol. To obtain the planned rate, investigators should make efforts to inform patients and their families about the medical contributions a surgical RCT can make and recognize that the period in equipoise may be limited.

Prout H, Tod A, Neal R, Nelson A. Maximising recruitment of research participants into a general practice based randomised controlled trial concerning lung diagnosis—staff insights from an embedded qualitative study. Trials 2022; 23:225. [PMID: 35313926 PMCID: PMC8935731 DOI: 10.1186/s13063-022-06125-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Accepted: 02/20/2022] [Indexed: 11/22/2022] Open
Abstract
Background The ELCID Trial was a feasibility randomised controlled trial examining the effect on lung cancer diagnosis of lowering the threshold for referral for urgent chest X-ray for smokers and recent ex-smokers, aged over 60 with new chest symptoms. The qualitative component aimed to explore the feasibility of individually randomising patients to an urgent chest X-ray or not and to investigate any barriers to patient recruitment and participation. This would inform the design of any future definitive trial. This paper explores general practice staff insights into participating in and recruiting to diagnostic trials for possible/suspected lung cancer. Methods Qualitative interviews were conducted with 11 general practice staff which included general practitioners, a nurse practitioner, research nurses and practice managers. Interviews were analysed using a framework approach. Results Findings highlight general practice staff motivators to participate in the trial as recruiters, practice staff interactions with patients recruited onto the study, methods of organisation staff used to undertake the trial, the general impact of the trial on practice staff, how the trial research team supported the practices and lastly practice staff suggestions for trial delivery improvement. Conclusions The integration of a qualitative component focused on staff experiences participating in a lung diagnostic trial has demonstrated the feasibility to recruit for similar future studies within general practice. Although recruitment into trials can be difficult, results from our study offer suggestions on maximising patient recruitment not just to trials in general but also specifically for a lung diagnosis study.

Abstract
Background Clinical trials are key elements of the processes that account for many of the recent advances in cancer care. Unfortunately, they are becoming more challenging to conduct. Furthermore, a large number of clinical trials in oncology close early due to poor accrual. To identify opportunities for continued improvement in clinical trial enrollment, we sought to identify the obstacles encountered by our clinical trial research staff in these activities. Methods This is a prospective qualitative study, using Grounded Theory Methodology that was concluded at Stephenson Cancer Center (SCC). SCC has been the lead accruer to National Cancer Institute-Lead Academic Participating Sites (NCI-LAPS) trials over the past three years, and in addition, fields investigator-initiated and industry-sponsored trials. We conducted a survey of our research staff including all research nurses and disease site coordinators who participate in recruitment, screening, consenting, data collection, and compliance for interventional clinical trials. We then performed a follow-up meeting with our research coordinators to clarify responses. The study objectives were to highlight common barriers to recruiting adult cancer patients, encountered by research coordinators from all disease sites and to propose effective solutions to identified barriers. Results We are reporting our results of investigating barriers to clinical trials enrollment from a new perspective. The most commonly reported obstacles for clinical trials enrollment from our research staff's perspective were categorized into five themes: clinical trials protocol, communication barriers and cultural beliefs, financial barriers, patients' comorbidities and performance status, and physicians’ commitment. Conclusions Although assessing barriers encountered by clinical research staff is an infrequently used metric for improving clinical trial enrollment, it provides an important perspective in the field. Implementing interventions to improve clinical trial feasibility and accrual is critical to improving cancer care.

Baseline characteristics and comparability of older multimorbid patients with polypharmacy and general practitioners participating in a randomized controlled primary care trial. BMC FAMILY PRACTICE 2021; 22:123. [PMID: 34157981 PMCID: PMC8220761 DOI: 10.1186/s12875-021-01488-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Accepted: 06/09/2021] [Indexed: 11/15/2022]
Abstract
Objectives Recruiting general practitioners (GPs) and their multimorbid older patients for trials is challenging for multiple reasons (e.g., high workload, limited mobility). The comparability of study participants is important for interpreting study findings. This manuscript describes the baseline characteristics of GPs and patients participating in the ‘Optimizing PharmacoTherapy in older multimorbid adults In primary CAre’ (OPTICA) trial, a study of optimization of pharmacotherapy for multimorbid older adults. The overall aim of this study was to determine if the GPs and patients participating in the OPTICA trial are comparable to the real-world population in Swiss primary care. Design Analysis of baseline data from GPs and patients in the OPTICA trial and a reference cohort from the FIRE (‘Family medicine ICPC Research using Electronic medical records’) project. Setting Primary care, Switzerland. Participants Three hundred twenty-three multimorbid (≥ 3 chronic conditions) patients with polypharmacy (≥ 5 regular medications) aged ≥ 65 years and 43 GPs recruited for the OPTICA trial were compared to 22,907 older multimorbid patients with polypharmacy and 227 GPs from the FIRE database. Methods We compared the characteristics of GPs and patients participating in the OPTICA trial with other GPs and other older multimorbid adults with polypharmacy in the FIRE database. We described the baseline willingness to have medications deprescribed of the patients participating in the OPTICA trial using the revised Patients’ Attitudes Towards Deprescribing (rPATD) questionnaire. Results The GPs in the FIRE project and OPTICA were similar in terms of sociodemographic characteristics and their work as a GP (e.g. aged in their fifties, ≥ 10 years of experience, ≥ 60% are self-employed, ≥ 80% work in a group practice). The median age of patients in the OPTICA trial was 77 years and 45% of trial participants were women. Patients participating in the OPTICA trial and patients in the FIRE database were comparable in terms of age, certain clinical characteristics (e.g. systolic blood pressure, body mass index) and health services use (e.g. selected lab and vital data measurements). More than 80% of older multimorbid patients reported to be willing to stop ≥ 1 of their medications if their doctor said that this would be possible. Conclusion The characteristics of patients and GPs recruited into the OPTICA trial are relatively comparable to characteristics of a real-world Swiss population, which indicates that recruiting a generalizable patient sample is possible in the primary care setting. Multimorbid patients in the OPTICA trial reported a high willingness to have medications deprescribed.

Abstract
OBJECTIVES To examine the feasibility and acceptability of breath research in primary care. DESIGN Non-randomised, prospective, mixed-methods cross-sectional observational study. SETTING Twenty-six urban primary care practices. PARTICIPANTS 1002 patients aged 18-90 years with gastrointestinal symptoms. MAIN OUTCOME MEASURES During the first 6 months of the study (phase 1), feasibility of patient enrolment using face-to-face, telephone or SMS-messaging (Short Message Service) enrolment strategies, as well as processes for breath testing at local primary care practices, were evaluated. A mixed-method iterative study design was adopted and outcomes evaluated using weekly Plan-Do-Study-Act cycles, focus groups and general practitioner (GP) questionnaires.During the second 6 months of the study (phase 2), patient and GP acceptability of the breath test and testing process was assessed using questionnaires. In addition a 'single practice' recruitment model was compared with a 'hub and spoke' centralised recruitment model with regards to enrolment ability and patient acceptability.Throughout the study feasibility of the collection of a large number of breath samples by clinical staff over multiple study sites was evaluated and quantified by the analysis of these samples using mass spectrometry. RESULTS 1002 patients were recruited within 192 sampling days. Both 'single practice' and 'hub and spoke' recruitment models were effective with an average of 5.3 and 4.3 patients accrued per day, respectively. The 'hub and spoke' model with SMS messaging was the most efficient combined method of patient accrual. Acceptability of the test was high among both patients and GPs. The methodology for collection, handling and analysis of breath samples was effective, with 95% of samples meeting quality criteria. CONCLUSIONS Large-scale breath testing in primary care was feasible and acceptable. This study provides a practical framework to guide the design of Phase III trials examining the performance of breath testing in primary care.

Factors affecting patient recruitment to trials: qualitative research in general practice. BJGP Open 2020; 4:bjgpopen20X101056.

Abstract
Background Patient recruitment to clinical research is often challenging and, when inadequate, can result in delayed or underpowered studies. Recruitment problems were experienced during a study of women with heavy menstrual bleeding in general practice (the MIRA trial). Although efforts were made to reduce the burden of the study for those participating, patient recruitment was still an issue. Aim To identify the barriers and facilitators associated with patient recruitment to clinical trials, as experienced by GPs. Design & setting A qualitative study was performed in Dutch general practice, using semi-structured interviews. Method GPs participating in the MIRA trial were selected by purposive sampling and interviewed until saturation was reached. Three independent researchers performed data coding and thematic analysis. Consensus on the identified themes was reached by discussion among the researchers. Results Sixteen GPs were interviewed. The following factors were noted to influence recruitment: the incidence of the disease under study; awareness of the study; attitude towards scientific research; perceived burden for the patient; usual care by the GP; time investment; characteristics of the GP and their practice; and patient experience of research participation. Conclusion The identified barriers and facilitators associated with patient recruitment highlight the areas in which future studies can be improved. Indeed, benefits could be gained by simply ensuring that study procedures are clear, by requiring limited (time) investment from the GP, and by investing in personal communication and reminders to keep the GP motivated and interested. Placing greater importance on scientific research during the GP training programme could also serve as a means to motivate future GPs to integrate scientific research in their clinical practice.

Abstract
OBJECTIVE To assess the effect of a personalized newsletter compared with a standard newsletter on patient recruitment in physiotherapy research. METHODS We performed a cluster-randomized trial including 120 physiotherapists who recruited patients for a prospective cohort and were randomly assigned to either receiving personalized feedback in a newsletter (intervention group) or a standard newsletter (control group). We calculated the difference in the number of patients included in the study corrected for inclusion time between both groups. RESULTS The physiotherapists in the control group (n = 59) included 110 patients (35.4% of the total number of patients included) compared with an inclusion of 200 patients (64.6% of the total number of patients included) by the physiotherapists in the intervention group (n = 61), a difference of 90 patients in favor of the intervention group. However, when corrected for inclusion time and a cluster effect, we found no statistically significant difference between both groups. In addition, therapists who did not include a single patient (inactive therapists) were evenly divided between the 2 groups (n = 29 [49%] in the control group; n = 30 [49%] in the intervention group). CONCLUSIONS A personalized newsletter does not significantly increase the number of recruited patients by physiotherapists. However, therapists receiving personalized feedback recruited nearly double the number of patients compared with the ones receiving standard feedback.

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.

Abstract
AIM To assess the feasibility and effectiveness of a low-complexity, low-cost model of caregiver education in primary care, targeted to reduce hospitalizations of heart failure patients. METHODS A cluster-randomized, controlled, open trial was proposed to general practitioners, who were invited to identify patients with heart failure, exclusively managed at home and continuously attended by a caregiver. Participating general practitioners were then randomized to: usual treatment; caregiver education (educational session for recognizing early symptoms/signs of heart failure, with recording in a diary of a series of patient parameters, including body weight, blood pressure, heart rate). The patients were observed at baseline and during a 12-month follow-up. RESULTS Three hundred and thirteen patients were enrolled (163 in the intervention, 150 in the usual care group), 63% women, mean age 85.3 ± 7.7 years. At the end of the 12-month follow-up, a trend towards a lower incidence of hospitalizations was observed in the intervention group (hazard ratio 0.73; 95% CI 0.53-1.01 P = 0.061). Subgroup analysis showed that for patients with persistent/permanent atrial fibrillation, age less than 90 years or Barthel score equal to or greater than 50 a significant lower hospital admission rate occurred in the intervention group (hazard ratio 0.63; 95% CI 0.39-0.99; P = 0.048, hazard ratio 0.66; 95% CI 0.45-0.97; P = 0.036 and hazard ratio 0.61; 95% CI 0.41-0.89; P = 0.011, respectively). CONCLUSION Caregivers training for early recognition of symptoms/signs of worsening heart failure may be effective in reducing hospitalizations, although the benefit was evident only in specific patient subgroups (with persistent/permanent atrial fibrillation, age <90 years or Barthel score ≥ 50), with only a positive trend in the whole cohort.

Abstract
BACKGROUND We conducted a pilot study of an intervention to facilitate patients' agenda setting in clinical consultations. The primary aim of the study was to test the feasibility of running the randomized controlled trial. A secondary objective was to assess the extent to which patient and public involvement (PPI) could contribute to the process of qualitative data analysis (QDA). AIMS To describe a novel approach to including patient partners in QDA; to illustrate the kinds of contribution that patient partners made to QDA in this context; and to propose a characterization of a process by which patient involvement can contribute to knowledge production. METHODS Six patient and public representatives were supported to contribute to data analysis via a range of modalities. During a series of QDA workshops, experienced research staff role-played consultations and interviews, and provided vignettes. Workshop data and PPI diaries were analysed using thematic discourse analysis. RESULTS We characterized a process of thesis, antithesis and synthesis. This PPI group contributed to the rigour and validity of the study findings by challenging their own and the researchers' assumptions, and by testing the emerging hypotheses. By training PPI representatives to undertake qualitative data analysis, we transformed our understanding of doctor-patient consultations. CONCLUSIONS This research required changes to our usual research practices but was in keeping with the objective of establishing meaningful patient involvement for a future definitive trial. This work was informed by concepts of critical humility, and a process of knowledge production enabled via the construction of a knowledge space.

Discontinuation of a randomised controlled trial in general practice due to unsuccessful patient recruitment. BJGP Open 2017; 1:bjgpopen17X101085.

Abstract
Background A randomised controlled trial (RCT) in general practice, recruiting incident patients with (sub)acute sciatica, was discontinued because of insufficient recruitment. Aim To describe factors that influenced the recruitment process and ultimately led to discontinuation of this trial, and to enable others to learn from this experience. Design & setting A pragmatic RCT was designed to compare two pain medication prescription strategies for treatment of (sub)acute sciatica in general practice. After 1 year of patient recruitment, the trial was prematurely terminated. Method To analyse the underperforming recruitment, patient information systems of 20 general practices were screened twice a month to search for eligible patients and identify reasons for non-eligibility. Secondly, after study termination, an open question was distributed to the participating GPs for their views on the recruitment process. Results A total of 116 GPs from 37 general practices collaborated in the trial. Only eight of 234 patients were included after 12 months. The 22 GPs who offered their opinion on the main reasons for unsuccessful recruitment considered that these were the low incidence rate and strict eligibility criteria, a strong patient and/or GP preference, and time constraints. Conclusion For this RCT, multiple factors were related to recruitment problems but it remains unknown which determinants prevailed. As the research question is unanswered but remains relevant, it is recommended that GPs' daily practice is taken into account when designing an RCT, a pilot study should be performed for feasibility of recruitment, and GP assistants should be involved at an early stage.

Abstract
BACKGROUND In 2009, we began recruiting dental practitioners across Germany to participate in a clinical trial to evaluate the clinical performance of EQUIA, a new glass ionomer restoration material. The aim of this paper is to discuss the outcomes of the dental practitioner recruitment and outline the process of establishing a practice-based research network. METHODS Study proposals were sent to randomly selected dental offices in 29 cities in Germany. The proposals were sent until a minimum of 10 clinics in each city declared participation. Later on, briefing lectures informed the participating practitioners about the design, methods, and material application procedure. Participants were familiarized with the guidelines of Good Manufacturing Practice (GMP) and Good Epidemiological Practice (GEP). A questionnaire describing the characteristics of each dental office was filled out by the participating practitioner. Additionally, participation levels were characterized according to the socioeconomic status and geographic districts of residence in Germany (Regions 0 to 9). The associations between the characteristics were tested by the Kruskal-Wallis Test and Chi-squared test (P < 0.05). RESULTS A total of 3194 private dental clinics were invited, 1712 clinics refused to participate, 1195 did not respond to the invitation, and 323 agreed to participate. Only 144 clinics participated in the lectures held in their cities and signed the participation agreement. Based on their geographic location, the highest participation was in Region 2 with a participation rate of 14.3%, and the lowest participation was in Region 6 with a participation rate of 1.7%. Regions with the lowest rate of unemployment and relatively higher rates of income (Regions 7 and 8) had the highest rate of refusals (86%). CONCLUSION The initial results of the dental practitioner recruitment in this study suggest that the recruitment and pre-randomization design were successful, and by reaching out to a considerable number of private dental clinics to participate, we were able to recruit a smaller number of highly motivated dentists in this clinical study. Regional differences in socioeconomic status, practitioner specialization, and differences in patient health care insurance have to be considered when recruiting dental practitioners for clinical trials. TRIAL REGISTRATION The trial has been registered at Deutsches Register Klinischer Studien (German register of clinical trials) on 6 September 2012 under DRKS-ID: DRKS00004220.

Abstract
AIMS To discuss the practical aspects of conducting research in a primary care setting, from the perspectives of the practitioner and the research team. METHODS Various issues are discussed, including the relevance of research questions being generated in this setting, the advantages to both parties and the processes involved in conducting a study in specialist practice. This paper describes two recent studies (a randomized clinical trial and a qualitative study) conducted within specialist practice, to illustrate some of the potential difficulties. CONCLUSIONS The success of conducting a study in primary care is determined by a variety of factors, including an interested specialist practitioner, motivated staff in a well-organized practice and the close support of an academic-based research team.

Abstract
BACKGROUND Psychological therapy is effective for symptoms of mental distress, but many groups with high levels of mental distress face significant barriers in terms of access to care, as current interventions may not be sensitive to their needs or their understanding of mental health. There is a need to develop forms of psychological therapy that are acceptable to these groups, feasible to deliver in routine settings, and clinically and cost effective. METHODS We developed a culturally sensitive wellbeing intervention with individual, group and sign-posting elements, and tested its feasibility and acceptability for patients from ethnic minorities and older people in an exploratory randomised trial. RESULTS We recruited 57 patients (57% of our target) from 4 disadvantaged localities in the NW of England. The results of the exploratory trial suggest that the group receiving the wellbeing interventions improved compared to the group receiving usual care. For elders, the largest effects were on CORE-OM and PHQ-9. For ethnic minority patients, the largest effect was on PHQ-9. Qualitative data suggested that patients found the intervention acceptable, both in terms of content and delivery. CONCLUSIONS This exploratory trial provides some evidence of the efficacy and acceptability of a wellbeing intervention for older and ethnic minority groups experiencing anxiety and depression, although challenges in recruitment and engagement remain. Evidence from our exploratory study of wellbeing interventions should inform new substantive trial designs. TRIAL REGISTRATION Current controlled trials ISRCTN68572159.

Abstract
The need for more evidence-based interventions in primary care is clear. However, it is challenging to recruit general practitioners (GPs) for interventional research. This paper reports on the evaluation of three methods of recruitment that were sequentially used to recruit GPs for a randomised controlled trial of an asthma communication and education intervention in Australia. The recruitment methods (RMs) were: general practices were contacted by project staff from a Department of General Practice, University of Sydney (RM1); general practices were contacted by staff from an independent research organisation (RM2); and general practices were contacted by a medical peer (chief investigator) (RM3). A GP was defined as 'recruited' once they consented and were randomised to a group, and 'retained' if they provided baseline data and did not notify staff of their intention to withdraw at any time during the 12-month study. RM1 was used for the first 6 months, during which 34 (4%) GPs were recruited and 21 (62%) retained from a total of 953 invitations. RM2 was then used for the next 5 months, during which 32 (6%) GPs were recruited and 26 (81%) were retained. Finally over the next 7 months, RM3 recruited 84 (12%) GPs and retained 75 (89%) GPs. In conclusion, use of a medical peer as the first contact was associated with the highest recruitment and retention rate.

Abstract
BACKGROUND Recruiting to randomized controlled trials is fraught with challenges; with less than one third recruiting to their original target. In preparation for a trial evaluating the effectiveness of a blood test to screen for lung cancer (the ECLS trial), we conducted a qualitative study to explore the potential barriers and facilitators that would impact recruitment. METHODS Thirty two people recruited from community settings took part in four focus groups in Glasgow and Dundee (UK). Thematic analysis was used to code the data and develop themes. RESULTS Three sub-themes were developed under the larger theme of recruitment strategies. The first of these themes, recruitment options, considered that participants largely felt that the invitation to participate letter should come from GPs, with postal reminders and face-to-face reminders during primary care contacts. The second theme dealt with understanding randomization and issues related to the control group (where bloods were taken but not tested). Some participants struggled with the concept or need for randomization, or for the need for a control group. Some reported that they would not consider taking part if allocated to the control group, but others were motivated to take part even if allocated to the control group by altruism. The final theme considered perceived barriers to participation and included practical barriers (such as flexible appointments and reimbursement of travel expenses) and psychosocial barriers (such as feeling stigmatized because of their smoking status and worries about being coerced into stopping smoking). CONCLUSIONS Focus groups provided useful information which resulted in numerous changes to proposed trial documentation and processes. This was in order to address participants information needs, improve comprehension of the trial documentation, enhance facilitators and remove barriers to participation. The modifications made in light of these findings may enhance trial recruitment and future trials may wish to consider use of pretrial focus groups.

Abstract
BackgroundEvidence-based interventions exist for common mental health problems. However, many people are unable to access effective care because it is not available to them or because interactions with caregivers do not address their needs. Current policy initiatives focus on supply-side factors, with less consideration of demand.Aim and objectivesOur aim was to increase equity of access to high-quality primary mental health care for underserved groups. Our objectives were to clarify the mental health needs of people from underserved groups; identify relevant evidence-based services and barriers to, and facilitators of, access to such services; develop and evaluate interventions that are acceptable to underserved groups; establish effective dissemination strategies; and begin to integrate effective and acceptable interventions into primary care.Methods and resultsExamination of evidence from seven sources brought forward a better understanding of dimensions of access, including how people from underserved groups formulate (mental) health problems and the factors limiting access to existing psychosocial interventions. This informed a multifaceted model with three elements to improve access: community engagement, primary care quality and tailored psychosocial interventions. Using a quasi-experimental design with a no-intervention comparator for each element, we tested the model in four disadvantaged localities, focusing on older people and minority ethnic populations. Community engagement involved information gathering, community champions and focus groups, and a community working group. There was strong engagement with third-sector organisations and variable engagement with health practitioners and commissioners. Outputs included innovative ways to improve health literacy. With regard to primary care, we offered an interactive training package to 8 of 16 practices, including knowledge transfer, systems review and active linking, and seven agreed to participate. Ethnographic observation identified complexity in the role of receptionists in negotiating access. Engagement was facilitated by prior knowledge, the presence of a practice champion and a sense of coproduction of the training. We developed a culturally sensitive well-being intervention with individual, group and signposting elements and tested its feasibility and acceptability for ethnic minority and older people in an exploratory randomised trial. We recruited 57 patients (57% of target) with high levels of unmet need, mainly through general practitioners (GPs). Although recruitment was problematic, qualitative data suggested that patients found the content and delivery of the intervention acceptable. Quantitative analysis suggested that patients in groups receiving the well-being intervention improved compared with the group receiving usual care. The combined effects of the model included enhanced awareness of the psychosocial intervention among community organisations and increased referral by GPs. Primary care practitioners valued community information gathering and access to the Improving Access to Mental Health in Primary Care (AMP) psychosocial intervention. We consequently initiated educational, policy and service developments, including a dedicated website.ConclusionsFurther research is needed to test the generalisability of our model. Mental health expertise exists in communities but needs to be nurtured. Primary care is one point of access to high-quality mental health care. Psychosocial interventions can be adapted to meet the needs of underserved groups. A multilevel intervention to increase access to high-quality mental health care in primary care can be greater than the sum of its parts.Study registrationCurrent Controlled Trials ISRCTN68572159.FundingThe National Institute for Health Research Programme Grants for Applied Research programme.

Recruitment for a clinical trial of chronic disease self-management for older adults with multimorbidity: a successful approach within general practice. BMC FAMILY PRACTICE 2013; 14:125.

Abstract
Background A robust research base is required in General Practice. The research output for General Practice is much less than those of other clinical disciplines. A major impediment to more research in this sector is difficulty with recruitment. Much of the research in this area focuses on barriers to effective recruitment and many projects have great difficulty with this process. This paper seeks to describe a systematic approach to recruitment for a randomized controlled trial that allowed the study team to recruit a substantial number of subjects from General Practice over a brief time period. Methods A systematic approach to recruitment in this setting based on prior literature and the experience of the investigator team was incorporated into the design and implementation of the study. Five strategies were used to facilitate this process. These included designing the study to minimize the impact of the research on the day-to-day operations of the clinics, engagement of general practitioners in the research, making the research attractive to subjects, minimizing attrition and ensuring recruitment was a major focus of the management of the study. Outcomes of the recruitment process were measured as the proportion of practices that agreed to participate, the proportion of potentially eligible subjects who consented to take part in the trial and the attrition rate of subjects. Qualitative interviews with a subset of successfully recruited participants were done to determine why they chose to participate in the study; data were analyzed using thematic analysis. Results Five out of the six general practices contacted agreed to take part in the study. Thirty-eight per cent of the 1663 subjects who received a letter of invitation contacted the university study personnel regarding their interest in the project. Recruitment of the required number of eligible participants (n = 256) was accomplished in seven months. Thematic analysis of interviews with 30 participants regarding key factors in their study participation identified a personalised letter of endorsement from their general practitioner, expectation of personal benefit and altruism as important factors in their decision to participate. Conclusion Recruitment can be successfully achieved in General Practice through design of the research project to facilitate recruitment, minimize the impact on general practice operations and ensure special care in enrolling and maintaining subjects in the project.

Abstract
BACKGROUND There is growing attention towards increasing patient and service user engagement (PSUE) in biomedical and health services research. Existing variations in language and design inhibit reporting and indexing, which are crucial to comparative effectiveness in determining best practices. OBJECTIVE This paper utilizes a systematic review and environmental scan to derive an evidence-based framework for PSUE. DESIGN A metanarrative systematic review and environmental scan/manual search using scientific databases and other search engines, along with feedback from a patient advisory group (PAG). ELIGIBLE SOURCES English-language studies, commentaries, grey literature and other sources (including systematic and non-systematic reviews) pertaining to patient and public involvement in biomedical and health services research. DATA EXTRACTED Study description (e.g. participant demographics, research setting) and design, if applicable; frameworks, conceptualizations or planning schemes for PSUE-related endeavours; and methods for PSUE initiation and gathering patients'/service users' input or contributions. RESULTS Overall, 202 sources were included and met eligibility criteria; 41 of these presented some framework or conceptualization of PSUE. Sources were synthesized into a two-part framework for PSUE: (i) integral PSUE components include patient and service user initiation, reciprocal relationships, colearning and re-assessment and feedback, (ii) sources describe PSUE at several research stages, within three larger phases: preparatory, execution and translational. DISCUSSION AND CONCLUSIONS Efforts at developing a solid evidence base on PSUE are limited by the non-standard and non-empirical nature of much of the literature. Our proposed two-part framework provides a standard structure and language for reporting and indexing to support comparative effectiveness and optimize PSUE.

Abstract
BACKGROUND There is a 20-year delay between the development of effective interventions for individuals with severe mental illness and widespread adoption in public mental health care settings. Academic-provider collaborations can shorten this gap, but establishing and maintaining partnerships entail significant challenges. AIMS This paper identifies potential barriers to academic-provider research collaborations and provides guidelines to overcome these obstacles. METHOD Authors from an academic institution and community mental health organization outline the components of their long-standing partnership, and discuss the lessons learned that were instrumental in establishing the collaborative model. Results Realistic resource allocation and training, a thorough understanding of the service model and consumer characteristics, systemic and bidirectional communication and concrete plans for post-project continuation are necessary at all project phases. CONCLUSIONS A shared decision-making framework is essential for effective academic institution and community mental health agency collaborations and can facilitate long-term sustainability of novel interventions.

Abstract
BACKGROUND Evidence suggests that poor recruitment into clinical trials rests on a patient 'deficit' model - an inability to comprehend trial processes. Poor communication has also been cited as a possible barrier to recruitment. A qualitative patient interview study was included within the feasibility stage of a phase III non-inferiority Randomized Controlled Trial (RCT) (SPARE, CRUK/07/011) in muscle invasive bladder cancer. The aim was to illuminate problems in the context of randomization. METHODS The qualitative study used a 'Framework Analysis' that included 'constant comparison' in which semi-structured interviews are transcribed, analyzed, compared and contrasted both between and within transcripts. Three researchers coded and interpreted data. RESULTS Twenty-four patients agreed to enter the interview study; 10 decliners of randomization and 14 accepters, of whom 2 subsequently declined their allocated treatment.The main theme applying to the majority of the sample was confusion and ambiguity. There was little indication that confusion directly impacted on decisions to enter the SPARE trial. However, confusion did appear to impact on ethical considerations surrounding 'informed consent', as well as cause a sense of alienation between patients and health personnel.Sub-optimal communication in many guises accounted for the confusion, together with the logistical elements of a trial that involved treatment options delivered in a number of geographical locations. CONCLUSIONS These data highlight the difficulty of providing balanced and clear trial information within the UK health system, despite best intentions. Involvement of multiple professionals can impact on communication processes with patients who are considering participation in RCTs. Our results led us to question the 'deficit' model of patient behavior. It is suggested that health professionals might consider facilitating a context in which patients feel fully included in the trial enterprise and potentially consider alternatives to randomization where complex interventions are being tested.

Abstract
BACKGROUND Since the 1990s there has been increasing emphasis on 'evidence-based medicine'. The randomized controlled trial is widely regarded as the 'gold-standard' study design for evaluating interventions. However, placing too strong an emphasis on a phase III trial, to the neglect of earlier development and piloting work, may result in weaker interventions that are more difficult to evaluate and less likely to be implemented. AIM To illustrate the benefits and outcomes of qualitative research at the early stages of the research continuum. SETTING/PARTICIPANTS Two cancer studies are evaluated in which the best treatment option is uncertain: ASPECTS (A Study of Patients ExperienCes of TreatmentS) and ProtecT (Prostate Testing for Cancer and Treatment). DESIGN To examine decision-making in relation to palliative chemotherapy for advanced cancer, ASPECTS was a qualitative study involving non-participant observation and recording of oncology consultations. During the ProtecT feasibility study, recruitment interviews were routinely audiotaped and in-depth interviews conducted with men to explore their understanding of treatment options and randomization to trial arms. RESULTS ASPECTS identified that insufficient information was given to patients about the survival benefits of palliative chemotherapy with implications for informed consent. ProtecT illustrated the effective use of qualitative research methods to resolve recruitment and randomization problems for a randomized controlled trial. CONCLUSIONS These studies illustrate the value of qualitative research, particularly during the earlier phases of the research continuum. Such research may generate hypotheses, strengthen the development and implementation of interventions and enhance their evaluation: all of which are essential to evidence-based medicine.

Abstract
Many cancer screening studies are conducted in primary care settings, yet few systematically analyze recruitment challenges found at these sites. During a randomized trial promoting colorectal cancer screening, we implemented a process evaluation of recruitment. Recruiters maintained logs that registered the numbers of patients entering the clinic, approached by recruiters, declining to participate, and reasons for nonapproach and nonparticipation. One half of age-eligible patients were approached (n = 1,489), and half of those who met basic eligibility requirements agreed to engage further (n = 527). A small proportion of patients (n = 98) completed the 15-min assessment before their appointment. Major reasons for nonapproach included previous approach, patients called to the exam room, and appearing ill. The major reason for nonparticipation was "not interested"; a few patients did not want to share contact information. Some participants exited the assessment midway because of further ineligibility or time limitations. Best-practice recommendations for recruitment in primary care are discussed.

Abstract
INTRODUCTION Internet based Cognitive Behavioural Therapy (iCBT) represents a significant development in the way psychological interventions are delivered. Studies tend to recruit via common media channels leading to criticisms of biased sample sizes and limited generalisability to primary care settings. AIM To evaluate the use of a prevalence recruitment strategy within primary care to recruit into an RCT examining a free to use iCBT intervention. METHODS Fully randomised controlled trial (RCT), utilising a prevalence based recruitment strategy, comparing the iCBT intervention with telephone support provided by NHS Direct Health Advisors with treatment-as-usual (TAU) control. RESULTS Recruitment rates were low with only 7 participants recruited over 8 months. Overall only 14% of expected study invitations were sent, with only 1% undertaking the consent and initial screening process. DISCUSSION Key differences with successful prevalence recruitment strategies highlight four main issues to consider when recruiting participants from primary care into iCBT studies--lack of equipoise, a need for an assertive approach, coding of depression in GP databases and help seeking behaviour in depression which can all act as potential contributors to failure to recruit. However other non-primary care recruitment methods, such as the use of media channels, which are already shown to be effective in non-primary care settings should be considered if these methods more accurately target the population who would be willing to adopt iCBT more generally.

Abstract
PURPOSE We undertook a study to evaluate the effectiveness of corticosteroid injections in primary care patients with greater trochanteric pain syndrome (GTPS). METHODS We evaluated the effect of corticosteroid injections compared with expectant treatment (usual care) in a pragmatic, multicenter, open-label, randomized clinical trial in the Netherlands. Patients (aged 18 to 80 years) with GTPS visiting 81 participating primary care physicians were randomly allocated to receive either local corticosteroid injections (n = 60) or usual care (n = 60). Primary outcomes of pain severity (numerical rating scale 0 to 10) and recovery (yes or no total or major recovery) were evaluated at 3-month and 12-month follow-up visits. Adverse events were collected at 6 weeks. RESULTS At the 3-month follow-up visit, 34% of the patients in the usual care group had recovered compared with 55% in the injection group (adjusted OR = 2.38; 95% CI, 1.14-5.00, number needed to treat = 5). Pain severity at rest and on activity decreased in both groups, but the decrease was greater in the injection group, for an adjusted difference in pain at rest of 1.18 (95% CI, 0.31-2.05) and in pain with activity of 1.30 (95% CI, 0.32-2.29). At the 12-month follow-up, 60% of the patients in the usual care group had recovered compared with 61% in the injection group (OR = 1.05; 95% CI, 0.50-2.27). Pain severity at rest and on activity decreased in both groups and the 12-month follow-up showed no significant differences, with adjusted differences of 0.14 (95% CI, -0.75 to 1.04) for pain at rest and 0.45 (95% CI, -0.55 to 1.46) for pain with activity. Aside from a short period with superficial pain at the site of the injection, no differences in adverse events were found. CONCLUSION In this first randomized controlled trial assessing the effectiveness of corticosteroid injections vs usual care in GTPS, a clinically relevant effect was shown at a 3-month follow-up visit for recovery and for pain at rest and with activity. At a 12-month follow-up visit, the differences in outcome were no longer present.

Abstract
The rapid development of new drugs, therapies, and devices has created a dramatic increase in the number of clinical research studies that highlights the need for greater participation in research by physicians as well as patients. Furthermore, the potential of clinical research is unlikely to be reached without greater participation of physicians in research. Physicians face a variety of barriers with regard to participation in clinical research. These barriers are system-or organization-related as well as research-and physician-related. To encourage physician participation, appropriate organizational and operational infrastructures are needed in health care institutes to support research planning and management. All physicians should receive education and training in the fundamentals of research design and methodology, which need to be incorporated into undergraduate medical education and postgraduate training curricula and then reinforced through continuing medical education. Medical schools need to analyze current practices of teaching-learning and research, and reflect upon possible changes needed to develop a 'student-focused teaching-learning and research culture'. This article examines the barriers to and benefits of physician participation in clinical research as well as interventions needed to increase their participation, including the specific role of undergraduate medical education. The main challenge is the unwillingness of many physicians and patients to participate in clinical trials. Barriers to participation include lack of time, lack of resources, trial-specific issues, communication difficulties, conflicts between the role of clinician and scientist, inadequate research experience and training for physicians, lack of rewards and recognition for physicians, and sometimes a scientifically uninteresting research question, among others. Strategies to encourage physician participation in clinical research include financial and nonfinancial incentives, adequate training, research questions that are in line with physician interests and have clear potential to improve patient care, and regular feedback. Finally, encouraging research culture and fostering the development of inquiry and research-based learning among medical students is now a high priority in order to develop more and better clinician-researchers.

Abstract
BACKGROUND recruitment targets to randomized controlled trials (RCTs) are often not met. Many interventions are used to improve recruitment but there is little empirical evidence on whether these approaches work. OBJECTIVE to examine whether changes to the design and conduct of a primary care-based RCT were associated with changes in patient recruitment. METHODS an observational time series analysis of recruitment to a primary care-based multi-centre RCT of aspirin versus warfarin for stroke prevention, which involved 330 practices. Several changes to the trial protocol and procedures were made over the 4 years of patient recruitment. For each quarter throughout the recruitment period, the recruitment rate per 1000 total population in active practices was calculated. RESULTS the recruitment target of 930 patients was exceeded. Fluctuations in recruitment rate occurred during the recruitment period. Following protocol changes aimed to reduce clinical workload, there was a significant increase in recruitment during the final 6 months of the study, during a period when there was not a similarly large increase in the total population available. CONCLUSIONS these findings suggest that the conduct of a trial is an important consideration if studies are to recruit successfully. Expanding the number of centres may not be the most effective way to improve recruitment.

Abstract
The objective of this study was to identify factors associated with general practitioner (GP) participation and the recruitment of people to trials in primary care, based on data from two trials of interventions for treating chronic low back pain. The study was based on data from two randomized controlled trials (RCTs), one involving exercise, the other acupuncture, and subsequent reporting by GPs in a postal questionnaire. The exercise trial achieved 62% recruitment whereas the acupuncture trial achieved 100% recruitment. In both trials GPs most efficient at referring patients were those with a special interest in the subject area, and those known personally to the research team. A follow-up GP questionnaire found that both trials had maintained a high profile with over 80% of GPs, and successful recruitment strategies included project reminder letters, updates and personal contacts. Achieving target recruitment of patients in the acupuncture trial was aided by the deliberate application of lessons learned in the exercise trial, in particular the need to keep initial study entry criteria broad, with subsequent filtering undertaken by the study researcher. In addition the use of effective methods of maintaining the trial profile, the involvement of a GP advisor, the decision to maximize the recruitment of GPs early in the trial and the direct recruitment of interested individual GPs. The successful recruitment of patients to trials in primary care requires careful planning and continuous monitoring from the outset. Prior to starting recruitment, it is useful to identify previous trials in a similar environment in order to learn from their experience and optimize patient recruitment.

Abstract
INTRODUCTION Little evidence exists to guide investigators on the effectiveness and cost-effectiveness of various recruitment strategies in primary care research. The purpose of this study is to describe the effectiveness and cost-effectiveness of eight clinical trial recruitment methods for postmenopausal women in a community-based setting. METHODS A retrospective analysis of the yield and cost of eight different recruitment methods: 1) family physician (FP) recruiters, 2) FP referrals, 3) community presentations, 4) community events, 5) newsletters, 6) direct mailings, 7) posters, and 8) newspaper advertisements that were used to recruit postmenopausal women to a randomized clinical trial (RCT) evaluating the effectiveness of gabapentin in treating hot flashes. RESULTS We recruited 197 postmenopausal women from a total of 904 screened, with 291 of the remainder being ineligible and 416 declining to participate. Of the 904 women screened, 34 (3.8%) were from FP recruiters and 35 (3.9%) were from other FP referrals while 612 (67.7%) resulted from newspaper advertisements. Of the 197 women enrolled, 141 (72%) were from newspaper advertisements, with 26 (13%) following next from posters. Word of mouth was identified as an additional unanticipated study recruitment strategy. Metropolitan newspaper advertising at $112.73 (Canadian) per enrolled participant and posters at $119.98 were found to be cost-effective recruitment methods. CONCLUSION Newspaper advertisements were the most successful method to recruit postmenopausal women into a community-based, primary care RCT.

Abstract
Objective Metformin has had a 'black box' contraindication in diabetic patients with heart failure (HF), but many believe it to be the treatment of choice in this setting. Therefore, we attempted to conduct a pilot study to evaluate the feasibility of undertaking a large randomized controlled trial with clinical endpoints. Study Design The pilot study was a randomized double blinded placebo controlled trial. Patients with HF and type 2 diabetes were screened in hospitals and HF clinics in Edmonton, Alberta, Canada (population ~1 million). Major exclusion criteria included the current use of insulin or high dose metformin, decreased renal function, or a glycosylated hemoglobin <7%. Patients were to be randomized to 1500 mg of metformin daily or matching placebo and followed for 6 months for a variety of functional outcomes, as well as clinical events. Results Fifty-eight patients were screened over a six month period and all were excluded. Because of futility with respect to enrollment, the pilot study was abandoned. The mean age of screened patients was 77 (SD 9) years and 57% were male. The main reasons for exclusion were: use of insulin therapy (n = 23; 40%), glycosylated hemoglobin <7% (n = 17; 29%) and current use of high dose metformin (n = 12; 21%). Overall, contraindicated metformin therapy was the most commonly prescribed oral antihyperglycemic agent (n = 27; 51%). On average, patients were receiving 1,706 mg (SD 488 mg) of metformin daily and 12 (44%) used only metformin. Conclusion Despite uncertainty in the scientific literature, there does not appear to be clinical uncertainty with regards to the safety or effectiveness of metformin in HF making a definitive randomized trial virtually impossible.

Abstract
The new drug application database submitted to the US Food and Drug Administration for drug approval (phases I-III or phases 1-3) is limited both in scope and size. Although randomized controlled trials, the hallmark of phase III trials, are the gold standard for the drug-approval process, they invariably have a number of limitations, including relatively small sample sizes, selective populations, short follow-up, the use of intermediate (surrogate) endpoints (almost always), and limited generalizability. The challenges of monitoring drugs once approved are also numerous. After approval by the Food and Drug Administration, marketed drugs undergo continued scrutiny, and this scrutiny is increasing because of problems that have surfaced with some drugs after their approval. Postmarketing research includes a variety of study designs and the use of registries and self-reporting of drug side effects. Along with this has come great confusion about what postmarketing research is and what a phase IV study is. Among the important strengths of phase IV research are the exposure of a broader range of patients to the drug under study, resulting in more "real-world" information about the drug's safety and efficacy, and consideration of a broader range of clinical endpoints. As a result, phase IV, or postmarketing research, has become an integral part of the drug evaluation process for a wide range of agents. The authors discuss the different types of study designs that are common under the phase IV terminology and provide some examples. They also discuss the use of registries and self-reporting of adverse events using the MedWatch System.

Abstract
BACKGROUND Lung cancer has the highest mortality-rate per cancer, with an overall 5-year survival <15%. Several non-randomized studies pointed out the high sensitivity of low dose computed tomography (LDCT) to detect early stage lung cancer. In France, Depiscan, a pilot RCT of LDCT versus chest X-ray (CXR), started on October 2002 to determine the feasibility of enrollment by general practitioners (GPs), investigations and diagnostic procedures by university hospital radiologists and multidisciplinary teams, data management by centralized clinical research assistants, and anticipate the future management of a large national trial. METHODS GPs and occupational physicians (OPs) selected and enrolled 1000 subjects in 1 year. Eligible subjects were asymptomatic males or females aged 50-75 years with a current or former cigarette smoking history of >/=15 cigarettes per day for at least 20 years (former smokers having quit <15 years prior to enrollment). Based to randomization, annual LDCT or CXR screenings were planned at baseline and annually for 2 years. RESULTS Between October 2002 and December 2004, 765 subjects were enrolled by 89 out of the 232 participating GPs and OPs. Complete clinical and imaging baseline data were available for 621 individuals out of the 765 enrolled, due to 144 noncompliant subjects who withdrew their consent. At least one nodule was detected in 152 out of 336 subjects (45.2%) in the LDCT screening, versus 21 out of 285 subjects (7.4%) in the CXR screening arm. Eight lung cancers were detected in the LDCT arm and one in the CXR arm. DISCUSSION This pilot trial allows estimating that non-calcified nodules are 10 [6.36-17.07] times more often detected from LDCT than from CXR. However enrollment by GPs was more difficult than expected with 41% active investigators and a high rate (19%) of noncompliant patients. This experience speaks to the need for a high level of GPs formation and a large, coordinated clinical research team in such a trial. TRIAL REGISTRATION NUMBER 02526.

Abstract
OBJECTIVE To test the effect of postal randomization on recruitment of patients into a randomized trial in primary care. STUDY DESIGN AND SETTING General practices used a telephone service to randomize patients in our trial. Delays in the start of recruitment at some sites led us to modify the randomization procedure. When new practices took part patients completed and posted baseline materials to the Trial Secretary in York who performed the randomization and informed those concerned of the allocation. RESULTS Of the 647 practices who were invited to take part, 130 (45%) of 288 agreed to participate using telephone randomization and 155 (43%) of 359 using the postal method. These practices recruited 553 patients from November 2002 to October 2004 across 11 sites in the United Kingdom. The postal method reduced the number of patients recruited by a factor of 0.86 (95% confidence interval=0.62-1.20), or 14%. The number of general practitioners working in a practice significantly increased patient recruitment by a factor of 1.12 (1.05-1.20), whereas practice distance from hospital significantly decreased recruitment by a factor of 0.98 (0.97-0.99). CONCLUSION Postal randomization had no significant effect on recruitment of patients into our trial.

Abstract
OBJECTIVE To investigate the clinical course and prognostic factors of complaints of arm, neck, and shoulder. STUDY DESIGN AND SETTING A prospective cohort study in physical therapy practice. Participating physiotherapists recruited new consulters with musculoskeletal complaints of the neck and/or upper extremities. Participants filled in questionnaires at baseline, 3 months, and 6 months. The main outcome measure was the persistence of complaints over 6-month follow-up. Possible predictors like social and psychological factors, physical factors, and complaint specific factors were tested in univariate and multivariate logistic regression analyses for repeated measurements. RESULTS Of the 624 participants at baseline 543 (87%) returned at least one follow-up questionnaire. At 6-month follow-up, 40% had persisting pain and discomfort. Somatization, kinesiophobia, catastrophizing, and a long duration of complaints at baseline were significantly related to the persistence of complaints over 6 months in the total population. In those with paid work (77%), catastrophizing, low decision authority at work, and a long duration of complaints at baseline were significantly related to the persistence of complaints over 6 months. CONCLUSION 40% of the participants had persisting pain and discomfort after 6 months and mainly social and psychological factors played a role in this course.

Abstract
AIMS To determine the number of patients needed to be screened (NNS) and allocated (NNA) in order to include one participant in a randomized clinical trial (RCT), and to compare the characteristics of patients accepting or declining participation in the RCT. METHODS The recruitment process of an ongoing multicenter RCT, comparing surgical and non-surgical interventions after acute anterior cruciate ligament (ACL) injury of the knee is described. We use the known concept Number Needed to Screen (NNS) and introduce the new concept Number Needed to Allocate (NNA) as variables to support a priori sample size calculations of future investigations. RESULTS 560 patients were screened to identify 162 patients (29%) eligible for inclusion in the RCT. 41 of those declined participation for various reasons, the most common being unwillingness to undergo surgery (n=23) or unwillingness to risk conservative treatment (n=8). 19 patients were excluded after MRI assessment or arthroscopy. Thus, 102 (18%) patients were allocated to one of the two treatments in the RCT. The NNS was 5.5 individuals with an acute knee injury, and the NNA was 1.6 individuals eligible for inclusion, to include 1 patient in the RCT. Patients declining to participate in the RCT were more frequently self-employed and less frequently injured in sports activities than those accepting RCT participation. CONCLUSIONS We suggest that the a priori sample size calculation needs to be multiplied by at least 5.5 to provide an estimate of the number needed to screen, or 1.6 to provide an estimate of the number needed to allocate in order to include the desired number of patients in a trial comparing surgical and non-surgical treatment of the ACL injured patient.

Abstract
OBJECTIVE Research in general practice has grown considerably over the past decades, but many projects face problems when recruiting patients. Lasagna's Law states that medical investigators overestimate the number of patients available for a research study. We aimed to assess factors related to success or failure of recruitment in general practice research. STUDY DESIGN AND SETTING Survey among investigators involved in primary care research in The Netherlands. Face-to-face interviews were held with investigators of 78 projects, assessing study design and fieldwork characteristics as well as success of patient recruitment. RESULTS Studies that focused on prevalent cases were more successful than studies that required incident cases. Studies in which the general practitioner (GP) had to be alert during consultations were less successful. When the GP or practice assistant was the first to inform the patient about the study, patient recruitment was less successful than when the patient received a letter by mail. There was a strong association among these three factors. CONCLUSION Lasagna's Law also holds in Dutch primary care research: many studies face recruitment problems. Awareness of study characteristics affecting participation of GPs and patients may help investigators to improve their study design.

Abstract
UNLABELLED OBJECTIVE - METHOD: The purpose of this review is to explore the expectations of patients and physicians prior to participate to a clinical trial and their positive or negative experiences after participating. A systematic review of Medline database from 1966 to 2005 identified 79 papers reported patients and physicians perceptions of clinical trials (only 3 in French), whom 27 English surveys conducted on patients and physicians. RESULTS If primary patients' motivation for enrolment was altruistic, physicians wish to help their patient. After enrolment, the most perceived positive benefit for patients and physicians are, respectively, the emotional improvement and the greater opportunity for personal benefit offered to enrolled patients. Most physicians' negative experience included logistical difficulties while patients are unease with randomisation and often uncomfortable with medical procedures. Unlike patients, all physicians' expectations seem to be fulfilled. CONCLUSION The knowledge of patients' and physicians' perception of participation may improve recruitment in clinical trials.

Abstract
BACKGROUND Research on neck pain in primary care is sparse. The role of GPs in taking care of patients with neck pain has not been described so far. This study focused on interested in the interaction between patients and GPs in their first contact on a new episode of neck pain. AIM To describe GPs' management of acute neck pain in patients and to detail the diagnostic and therapeutic procedures undertaken by GPs and self-care by patients. DESIGN OF STUDY A prospective cohort study with 1-year follow up. SETTING General practice in The Netherlands. METHOD Patients consulting their GP for non-specific acute neck pain lasting no longer than 6 weeks were invited to participate. Questionnaires were collected from patients at baseline and after 6, 12, 26, and 52 weeks. Patients rated their recovery on a 7-point ordinal scale. RESULTS In total 187 patients were included. At baseline GPs prescribed medication for 42% of patients, mostly non-steroidal anti-inflammatory drugs (56%) or muscle relaxation medication (20%); 51% were referred to a physiotherapist. Seventy-four per cent of referred patients reported recovery at the end of the follow-up year, whereas 79% of non-referred patients reported recovery. Frequently-given advice by the GP was to 'wait and see' (23%), 'improve posture' and 'stay active' (22%) or to 'take a rest' (18%). Self-care by patients included different sources of heat application (79%) and exercises (57%). Complementary medicine was used in 12% of cases and 39% of patients visited their GP again during follow up. Consultation of a medical specialist and ordering of X-rays rarely occurred. CONCLUSION Management by GPs included a strategy to 'wait and see' for an expected favourable natural course supported by medication, or referral to a physiotherapist.

Abstract
BACKGROUND It is considered to be a fundamental ethical premise of human experimentation, that it should be carried out only where the effects of an intervention are unclear. The point at which it is considered that there is insufficient scientific and medical evidence to clearly state the superiority of an intervention has been termed equipoise. This concept has been the subject of much recent impassioned debate but little empirical research about the views of people involved in recruitment to randomized controlled trials (RCTs), and none in the particularly emotive area of neonatal intensive care. METHODS Thirty neonatologists recruiting into one or both of two neonatal RCTs in five centres in England were interviewed using a semi-structured schedule to explore their involvement in randomised trials. The interviews were tape-recorded and transcribed. Equipoise was one among a range of topics covered. Concepts relating to equipoise were identified by close reading of the entire interviews. Themes emerging from the data were noted in their contexts then discussed between the co-authors. Interviewees also completed a brief questionnaire about their demographic background, and their experience of research and RCTs. RESULTS Almost all the neonatologists used the concept of equipoise [using words and phrases such as uncertainty, lack of knowledge (or ignorance), strengths of views, and balancing of pros and cons] in their interview and, for most of them, equipoise seemed to be a useful term. They explored ideas about equipoise at the individual and community levels, and some linked equipoise with notions of the responsibility that should be exercised by the scientific and professional communities. They differed in the importance they gave to individual equipoise, and in how they reacted to threats to equipoise. Feelings of doubt about a trial and disturbed equipoise were more often expressed by more junior doctors. CONCLUSIONS Our findings suggest that the concept of equipoise goes beyond the idea of uncertainty. In part this is because it includes the balancing of benefit and harm; this balancing is part of a professional obligation and requires engagement with 'expert' knowledge. Equipoise could therefore be seen as 'active' or 'responsible' uncertainty. Elucidation of this difficult concept may help to facilitate recruitment for both clinicians and parents in future trials and thereby help to find answers to important clinical questions.

An assessment of willingness to participate in a randomized trial of arthroscopic knee surgery in patients with osteoarthritis. Contemp Clin Trials 2005; 26:169-78.

Abstract
Identifying barriers to recruitment into a randomized clinical trial can help researchers adjust recruitment strategies to maximize enrollment. To determine barriers to enrollment of patients in trials of knee osteoarthritis treatments, we recruited from three centers patients over age 45 who had both knee osteoarthritis and a meniscal tear. We described a hypothetical randomized trial of arthroscopic partial meniscectomy versus non-operative management and assessed patients' willingness to participate in such a trial. We elicited preferences for treatment along with information on age, sex, education level, race, work status, and pain. We examined the association between these factors and willingness to participate in the trial. Orthopedic surgeons identified 106 eligible osteoarthritis patients, of whom 12 could not be reached, 6 refused and 88 (83%) completed interviews. 63% were female, 55% were college graduates, 23% were non-white and mean age was 60+/-8. The mean WOMAC pain score was 56+/-23. 22% of patients stated that they were definitely willing to participate in the hypothetical trial, and 24% stated they were probably willing. Subjects lacking strong preferences for treatment stated a greater willingness to participate than those with strong preferences (36-14% definitely willing, chi(2) for trend, p=0.005). WOMAC pain score, age, education, work status and race were not associated with willingness to participate. Males were more likely than females to state a willingness to participate (39-11% definitely willing, p=0.005). Since OA affects females disproportionately, a better understanding of barriers to females' participation in trials may enhance future research on treatment of osteoarthritis. Effectively addressing a priori treatment preferences through patient education about the advantages and drawbacks of treatments may increase willingness to participate in trials.

Abstract
General practice research databases are increasingly used to study intended and unintended effects of treatments. However, confounding by indication remains a major problem. The randomized database study methodology has been proposed as a method to combine the strengths of observational database (generalizability) and the strength of the randomized clinical trial (RCT) design (randomization). We developed an infrastructure that enables the execution of randomized database studies with treatment randomization facilitated by a general practice research database. The requirements posed by the methodology of randomized database studies were facilitated by software components. Our assessment showed that it is technically possible to conduct randomized trials in general practice according to the randomized database design. The infrastructure facilitated the conduct of randomized database studies in general practice but some practical difficulties and methodological issues remain. The technical infrastructure seems to be both promising and potentially feasible to facilitate future randomized database studies, although the methodology needs to be evaluated in more detail.

Abstract
UNLABELLED Depression is common in general practice and lack of concordance is an important problem in its treatment. Homeopathy has few side effects and is generally associated with good compliance. We report a study investigating the feasibility of a trial to compare the effectiveness of homeopathy with a conventional antidepressant and placebo. OBJECTIVES To assess the feasibility of a general practice-based clinical trial comparing the effectiveness of individualised homeopathic treatment vs Fluoxetine (Prozac) vs placebo in the treatment of major depressive episodes of moderate severity. DESIGN Randomised, double-dummy, double-blind parallel group clinical trial. SETTING Lower Clapton Group Practice, East London. METHOD Patients were recruited through their general practitioners as they presented during a 9 month period. Recruitment target was 30 patients. Eligibility was confirmed by a consultant psychiatrist using standard criteria (DSM-IV) and instruments Hamilton Depression Scale (HAMD). Suicidal and psychotic patients were excluded, additional precautions against suicide were incorporated. There was a 1 week run-in period and patients showing spontaneous improvement were excluded. Homeopathic treatment was prescribed by a GP qualified in homeopathy, from a 'limited list' of 30 homeopathic medicines, with the help of decision support software. Patients were randomised to receive verum Fluoxetine and placebo homeopathy, or verum homeopathy and placebo Fluoxetine, or placebo homeopathy and placebo Fluoxetine. Treatment duration was 12 weeks. The outcomes were: adverse drug reactions, clinical global impression (CGI); HAMD; mini international psychiatric Interview; Pittsburgh sleep quality index; Side-effects checklist; Short Form 12; treatment credibility questionnaire; work and social disability scale. The primary outcome measures were HAMD and CGI. RESULTS A recruitment calculation indicated that over 230 suitable patients would be expected to attend the practice during the recruitment phase. Thirty one patients were referred for possible inclusion in the trial by their GPs. Twenty three met the entry criteria, 11 were randomised and 6 completed the study. Of the completers, one received homeopathy, 2 placebo and 3 Fluoxetine. CONCLUSIONS A trial of this design in general practice is not feasible, because of recruitment difficulties, many of them linked to patient preference. Different approaches are required to recruit adequate patient numbers to trials of this sort.

Abstract
Background Many medical specialities have reviewed the statistical content of their journals. To our knowledge this has not been done in general practice. Given the main role of a general practitioner as a diagnostician we thought it would be of interest to see whether the statistical methods reported reflect the diagnostic process. Methods Hand search of three UK journals of general practice namely the British Medical Journal (general practice section), British Journal of General Practice and Family Practice over a one-year period (1 January to 31 December 2000). Results A wide variety of statistical techniques were used. The most common methods included t-tests and Chi-squared tests. There were few articles reporting likelihood ratios and other useful diagnostic methods. There was evidence that the journals with the more thorough statistical review process reported a more complex and wider variety of statistical techniques. Conclusions The BMJ had a wider range and greater diversity of statistical methods than the other two journals. However, in all three journals there was a dearth of papers reflecting the diagnostic process. Across all three journals there were relatively few papers describing randomised controlled trials thus recognising the difficulty of implementing this design in general practice.

Abstract
In the UK, researchers' access to study populations and control over selection of participants is becoming increasingly constrained by data protection and research governance legislation. Intervening stages placed between researchers and the population they wish to study can have serious effects on recruitment and ultimately on the validity of studies. In this paper we describe our experiences of gaining access to patients for a study of palliative care in primary care. Despite considerable time and resources dedicated to recruitment, a smaller than anticipated study sample was achieved. We found that gatekeeping by ethics committees and practitioner control over sample selection were significant hurdles in accessing patients for the study. Gatekeeping responsibilities represent considerable challenges for researchers seeking to obtain a representative study sample, not just in palliative care, but for research in general in health care.

Abstract
OBJECTIVE To test the hypothesis that appropriate interventions delivered by midwives within usual primary maternity care, can assist women to stop or reduce the amount they smoke and facilitate longer duration of breast feeding. DESIGN, SETTING AND PARTICIPANTS In a cluster randomised trial of smoking education and breast-feeding interventions in the lower North Island, New Zealand, midwives were stratified by locality and randomly allocated into a control group and three intervention groups. The control group provided usual care. Midwives in the intervention groups delivered either a programme of education and support for smoking cessation or reduction, a programme of education and support for breast feeding or both programmes. Sixty-one midwives recruited a total of 297 women. INTERVENTIONS Structured programmes provided by midwives. FINDINGS Women receiving only the smoking cessation or reduction programme were significantly more likely to have reduced, stopped smoking or maintained smoking changes than women in the control group, at 28 weeks and 36 weeks gestation. Women receiving both the smoking cessation and breast-feeding education and support programmes were significantly more likely than women in the control group to have changed their smoking behaviour at 36 weeks gestation. There was no difference in rates of cessation or reduction between the groups in the postnatal period. There was no difference in rates of full breast feeding between the control and intervention groups for women who planned to breast feed. KEY CONCLUSIONS Education and support by midwives, as part of primary midwifery, can facilitate smoking cessation and reduction during pregnancy.

Abstract
BACKGROUND AND OBJECTIVE Recruitment to randomized trials is often difficult, but few studies have investigated interventions to improve recruitment. In a randomized trial nested within a trial of treatments for localized prostate cancer, we investigated the comparative effectiveness and cost-effectiveness of nurses and surgeons in recruiting patients. METHODS Men with localized prostate cancer were randomized to see a nurse or urologic surgeon for an "information appointment" in which they were asked to consent to the ProtecT treatment trial comparing surgery, radiotherapy, and active monitoring. Analysis was conducted by intention to treat using chi-square with 95% confidence intervals for proportions and differences between groups. An economic evaluation was performed using the duration of appointments and grade of recruitment staff. RESULTS Case-finding identified 167 men with localized prostate cancer. One hundred fifty (90%) took part in the recruitment trial. There was a 4.0% difference between nurses and surgeons in recruitment rates (67% nurses, 71% urologists, 95% CI -10.8% to +18.8%, P=.60). Cost-minimization analysis showed that nurses spent longer times with patients but surgeon costs were higher and nurses often supported surgeon-led clinics. CONCLUSION Nurses were as effective and more cost-effective recruiters than urologic surgeons. This suggests an increased role for nurses in recruiting patients to randomized trials.

Abstract
Recruitment to trials is known to be difficult. Previous research suggests that a crucial factor may be participants' difficulty with the concept of randomization. This study explored patients' perceptions of randomization and reasons for consent or refusal to participate in the ProtecT study (a randomized trial of surgery, radiotherapy, and monitoring for localized prostate cancer). In-depth interviews were conducted with 21 men diagnosed with localized prostate cancer who were invited to participate in the ProtecT treatment trial. Interviewees were selected purposefully from three U.K. clinical centers to ensure the inclusion of similar proportions of those agreeing or refusing random treatment allocation in each of the treatment groups. Interviews explored men's recall and understanding of chance, comparison, and equipoise, and reasons for consent/refusal of randomization and acceptance/rejection of treatment allocation. Data were analyzed methodically using the techniques of constant comparison. Checking of coding and interpretation was assured by four experienced qualitative researchers. Recall and understanding of the major principles of the randomized design were good and were similar for "chance" and "comparison" between those who consented to and refused randomization. Clinical equipoise, however, caused difficulty. Almost all recalled and understood it, but those who found it acceptable tended to consent to randomization and those who could not accept it tended to refuse to participate. Belief in clinical equipoise was key to participants' consent to randomization. Ensuring patients understand and accept equipoise may thus increase their readiness to consent to participate in trials. A priority for future research is to focus on the provision and presentation of suitable and effective trial information, concentrating in particular on the neglected concept of clinical equipoise.

Abstract
This study compares the efficiency of two methods of recruitment into a randomised controlled trial examining the cost-effectiveness of water therapy for elderly people with lower limb osteoarthritis. The direct cost of recruiting patients via general practice was 27.66 Pounds per patient (1.1 personnel hours/patient). The cost per recruited patient from a local newspaper article was 2.72 Pounds (0.2 personnel hours/patient). The cost differential between the two recruitment methods was largely owing to poor administration practices, difficulties in accessing patient information, and difficulties in contacting patients from the general practice computer database.
