Recruitment rates and reasons for community physicians' non-participation in an interdisciplinary intervention study on leg ulceration

Strategies to engage family physicians in primary care research: A systematic review

RATIONALE

Moving towards high quality primary health care, involving family physicians in primary care research becomes an essential prerequisite to ensures a better adoption and routinization of patient-centred, evidence-based practices.

AIM

To assess the effectiveness of strategies to engage family physicians in primary care research.

METHODS

We systematically reviewed evidence for strategies used to engage family physicians in primary care research. We included any study design that reported at least one quantitative outcome. Searches were carried out on MEDLINE, Embase, PsycINFO and Web of Science. Pairs of reviewers independently screened for publications in two stages using standardized forms. We performed data analysis through a narrative synthesis approach, using the Reasoned-action approach as framework.

RESULTS

A total of 4859 deduped records were identified of which 41 studies met the eligibility criteria and were included for analysis. The majority of studies (n = 35) investigated family physician's participation in a research project. They aimed to influence family physicians' intention (n = 7) or their ability (n = 3) to participate in a research project. Three types of strategies (compensation/incentive, recruitment by a peer and support from a research network or an academic institution) demonstrated a significant increase in participation rate. Methodological quality of the studies evaluating these strategies was relatively low. Few studies (n = 6) targeted research capacity-building programmes with no significant impact noted.

CONCLUSION

Numerous strategies have been used to engage family physicians in primary care research, but few studies evaluated their effectiveness in a rigorous way.

Promoting the use of a self-management strategy among novice chiropractors treating individuals with spine pain: A mixed methods pilot clustered-clinical trial

Background

The uptake of Self-Management Support (SMS) among clinicians is suboptimal. To date, few studies have tested knowledge translation (KT) interventions to increase the application of SMS in chiropractic teaching clinics.

Study objective

Evaluate the feasibility of implementing a KT intervention to promote the use of a SMS strategy among chiropractic interns, their supervisors, and individuals with spine pain compared to controls.

Methods

Mixed methods pilot clustered-clinical trial. Clusters of 16 Patient Management Teams were allocated to a complex KT intervention (online and workshop training). Primary feasibility outcomes for clinicians, interns and patients were rates of recruitment, retention, and adherence to protocol. A nominal group technique and interviews were used to seek end-users’ views on the implementation process, and generate possible solutions.

Results

In total, 16 (84%) clinicians, 65 (26%) interns and 42 patients agreed to participate. All clinicians in the intervention group completed all KT intervention components, 23 interns (85%) completed the online training and 14 interns (51.8%) attended the workshop training. All clinicians in the intervention and seven (78%) in the control group completed all outcome measures at baseline and 6-month follow-up, while 15 (55.6%) and 23 (60.5%) interns in the intervention and control groups completed the questionnaires at baseline and 6-month follow-up, respectively. Among patients, 10 (52.6%) and 12 (52.2%) in the intervention and control groups respectively completed the questionnaires at the end of the study. Based on interview findings, solutions to improve the feasibility of conducting a full trial include: making SMS a part of the internship, changing the time of introducing the study to the interns, and having more training on SMS.

Conclusion

Recruitment and retention of chiropractic interns and patients for a larger implementation trial in a single outpatient teaching clinic may be challenging.

Patient and physician perspectives on engaging in palliative and healthcare trials: a qualitative descriptive study

Background

Researchers are encountering increasing challenges in recruiting participants for palliative and healthcare research. This paper aims to understand challenges to and methods for engaging physicians and seriously ill patients and their caregivers in research studies.

Methods

Between October 2019 to July 2020, we conducted qualitative interviews with 25 patients, proxies, and caregivers participants who were eligible for a randomized controlled trial of home-based palliative care and 31 physicians from participating accountable care organizations. Using thematic analysis, we analyzed participants’ responses to identify concepts and key ideas within the text. From these initial concepts, core themes around barriers to research and preferred research recruitment approaches were generated.

Results

Themes from patient and caregiver interviews included time constraints, privacy concerns, lack of research familiarity, disconnect with research institution, self-perceived health status, and concerns with study randomization. Physician-identified barriers focused on time constraints and study randomization. Patient and caregiver recommendations for study recruitment included in-person recruitment, recruitment at healthcare providers’ offices, recruitment via mail, additional study information, and frequent calls. Physician recommendations were related to placement of flyers at clinics, financial incentives, and formal events.

Conclusions

Findings demonstrated that although patients and caregivers prefer that their physicians recruit them for health-related research studies, physicians identified time constraints as a consistent barrier to research involvement.

Recruitment in Health Services Research-A Study on Facilitators and Barriers for the Recruitment of Community-Based Healthcare Providers

In health services research, the recruitment of patients is oftentimes conducted by community-based healthcare providers. Therefore, the recruitment of these healthcare providers is a crucial prerequisite for successful patient recruitment. However, recruiting community-based healthcare providers poses a major challenge and little is known about its influencing factors. This qualitative study is conducted alongside a health services research intervention trial. The aim of the study is to investigate facilitators and barriers for the recruitment of community-based healthcare providers. A qualitative text analysis of documents and semi-structured interviews with recruiting staff is performed. An inductive–deductive category-based approach is used. Our findings identify intrinsic motivation and interest in the trial’s aims and goals as important facilitating factors in healthcare provider recruitment. Beyond that, extrinsic motivation generated through financial incentives or collegial obligation emerged as a conflicting strategy. While extrinsic motivation might aid in the initial enrollment of healthcare providers, it rarely resulted in active trial participation in the long run. Therefore, extrinsic motivational factors should be handled with care when recruiting healthcare providers for health services research intervention trials.

Nurse-led patient education for persons suffering from a venous leg ulcer in outpatient's clinics and homecare settings: A scoping review

AIM OF THIS STUDY

To provide an overview of the available nurse-led individualized educational interventions, for persons with Venous Leg Ulcer (VLUs) in an outpatient or homecare settings.

MATERIALS AND METHODS

For this scoping review, a search was performed between December 2019 and January 2020. To identify sources of evidence a systematic search was conducted in PubMed, CINAHL, Embase, PsychINFO, Web of Science and LiSSa as well as in clinical trial registers to identify sources of evidence. All types of evidence associated with a nurse led-intervention were included.

RESULTS

Fifteen sources of evidence met the inclusion criteria. Educational sessions varied in modality, content and duration. Education sessions were face to face and supported by written materiel. The content focused on compression therapy and exercises. The duration and numbers of sessions varied. The most reported health related outcomes was wound healing.

CONCLUSION

This scoping review provides a broad overview of the available evidence and ongoing research for individualized nurse-led education persons with VLUs. Variability in the literature was found, which suggests that more intervention studies are needed to test and evaluate efficacy of nurse-led patient education.

Guideline implementation in the Canadian chiropractic setting: a pilot cluster randomized controlled trial and parallel study

Background

Feasibility and pilot studies are recommended prior to embarking on large-scale costly confirmatory trials. The objectives were to determine the feasibility of conducting a cluster randomized controlled trial (C-RCT) to evaluate a complex knowledge translation (KT) intervention to improve the management of people with neck pain, and to identify challenges and potential solutions to conducting a fully powered C-RCT in the chiropractic setting.

Methods

Pilot C-RCT involving a nationally representative sample of chiropractors and patients. We invited 400 chiropractors and 150 patients to participate. Clinicians were randomized to receive either an online theory-based KT educational and brief action plan (BAP) intervention (intervention group) or a copy of a clinical practice guideline (control group). Study-related challenges were ascertained via mid-study phone interviews and end-of-study feedback questionnaires. Analyses focused on descriptive estimates of likely recruitment, retention, and adherence rates, and documentation of potential barriers.

Results

In total, 47 chiropractors (12%) agreed to participate and were randomized after resampling. Fifteen withdrew from the study, leaving a total of 32 (8%) participants. Eleven chiropractors in the intervention group completed the webinars and e-learning modules, two partially completed them and three did not register. Participating chiropractors recruited a total of 29 patients. Sixty-three percent (n = 7) of intervention and 56% (n = 10) of control group patients completed all outcome measures at both baseline and 3-months follow-up, attended follow-up visits and performed home exercises. Patients in the intervention group reported significant reductions in pain (mean 1.6, 95% CI 0.26–2.94, P = 0.027) and disability scores (9.8, 95% CI 3.68–15.91, P = 0.033) from baseline to 3-month follow-up. Key barriers to participation reported by chiropractors included lack of time, difficulties in recruiting patients, problems with the administration of study questionnaires, concern that the clinician-patient relationship might be jeopardized, and lack of assistance from office staff. Over half (55%) of the respondents in the intervention group encountered some difficulty registering or completing the educational modules.

Conclusion

Recruitment of clinicians and patients for a trial of a complex intervention can be challenging, and retention of participants after enrolment may be low. Future trials of this nature likely require multiple recruitment strategies to achieve desired sample sizes. Moreover, time-constraint issues are perceived particularly by clinicians as a major barrier to both study enrolment before, and protocol adherence during, their actual participation in a trial.

Trial registration

The study was registered at, NCT02483091, on 17th June 2015.

Barriers and enablers to patient recruitment for randomised controlled trials on treatment of chronic wounds: A systematic review

Randomised controlled trials represent the gold standard in intervention efficacy evaluation. However, suboptimal recruitment affects completion and the power of a therapeutic trial in detecting treatment differences. We conducted a systematic review to examine the barriers and enablers to patient recruitment for randomised controlled trials on chronic wound treatment. Review registration was under PROSPERO 2017:CRD42017062438. We conducted a systematic search of Ovid MEDLINE, EBSCOhost CINAHL, Ovid Cochrane Library, Ovid EMBASE, and Ovid PsycINFO databases in June 2017 for chronic wound treatment randomised controlled trials. Twenty-seven randomised controlled trials or qualitative studies met the inclusion criteria. Among the 24 randomised controlled trials, 21 were assessed as low quality in relation to recruitment, and 3 were assessed as high quality. All 27 studies reported barriers to recruitment in chronic wound randomised controlled trials. The reported barriers to recruitment were: study-related, patient-related, clinician-related, health system-related, and/or operational-related. No study reported recruitment enablers. To enhance randomised controlled trial recruitment, we propose the need for improved integration of research and clinical practice. To alleviate the problems arising from inadequate reporting of randomised controlled trials, the Consolidated Standards of Reporting Trials Statement could include an additional item on recruitment barriers. This approach will allow for increased awareness of the potential barriers to recruitment for Randomised controlled trials (RCTs) in both wound management and other health care research.

Lessons Learned Designing and Using an Online Discussion Forum for Care Coordinators in Primary Care

While an increasing number of researchers are using online discussion forums for qualitative research, few authors have documented their experiences and lessons learned to demonstrate this method's viability and validity in health services research. We comprehensively describe our experiences, from start to finish, of designing and using an asynchronous online discussion forum for collecting and analyzing information elicited from care coordinators in Patient-Centered Medical Homes across the United States. Our lessons learned from each phase, including planning, designing, implementing, using, and ending this private online discussion forum, provide some recommendations for other health services researchers considering this method. An asynchronous online discussion forum is a feasible, efficient, and effective method to conduct a qualitative study, particularly when subjects are health professionals.

A valuable approach to the use of electronic medical data in primary care research: Panning for gold

Background:

Electronic medical data (EMD) from electronic health records of general practice computer systems have enormous research potential, yet many variables are unreliable.

Objective:

The aim of this study was to compare selected data variables from general practice EMD with a reliable, representative national dataset (Bettering the Evaluation and Care of Health (BEACH)) in order to validate their use for primary care research.

Method:

EMD variables were compared with encounter data from the nationally representative BEACH program using χ2 tests and robust 95% confidence intervals to test their validity (measure what they reportedly measure). The variables focused on for this study were patient age, sex, smoking status and medications prescribed at the visit.

Results:

The EMD sample from six general practices in the Illawarra region of New South Wales, Australia, yielded data on 196,515 patient encounters. Details of 90,553 encounters were recorded in the 2013 BEACH dataset from 924 general practitioners. No significant differences in patient age ( p = 0.36) or sex ( p = 0.39) were found. EMD had a lower rate of current smokers and higher average scripts per visit, but similar prescribing distribution patterns.

Conclusion:

Validating EMD variables offers avenues for improving primary care delivery and measuring outcomes of care to inform clinical practice and health policy.

Collaborative nurse-led self-management support for primary care patients with anxiety, depressive or somatic symptoms: Cluster-randomised controlled trial (findings of the SMADS study)

BACKGROUND

Collaborative, nurse-led care is a well-established model of ambulatory care in many healthcare systems. Nurses play a key role in managing patients' conditions as well as in enhancing symptom- and self-management skills.

OBJECTIVE

The SMADS trial evaluated the effectiveness of a primary care-based, nurse-led, complex intervention to promote self-management in patients with anxiety, depressive or somatic symptoms. Change in self-efficacy 12 months post baseline was used as the primary outcome.

DESIGN

The SMADS trial set up a two-arm, cluster randomised controlled trial in the city of Hamburg, a large metropolitan area in the North West of Germany.

SETTING

We randomly allocated participating primary care practices to either the intervention group (IG), implementing a nurse-led collaborative care model, or to the control group (CG), where patients with the above psychosomatic symptoms received routine treatment.

PARTICIPANTS

Patients from 18 to 65 years of age, regularly consulting a participating primary care practice, scoring≥5 on the anxiety, depressive or somatic symptom scales of the Patient Health Questionnaire (PHQ-D), German version.

METHODS

A mixed model regression approach was used to analyse the outcome data. Analyses were based on the intention-to-treat population: All enrolled patients were analysed at their follow-up. Additionally, we reported results as effect sizes. The robustness of the results was investigated by performing an observed cases analysis.

RESULTS

325 participants (IG N=134, CG N=191) from ten practices in each study arm consented to take part and completed a baseline assessment. The mean group difference (ITT-LOCF, IG vs. CG) in self-efficacy at the post baseline follow-up (median 406days) was 1.65 points (95% CI 0.50-2.8) in favour of IG (p=0.004). This amounts to a small Cohen's d effect size of 0.33. An observed cases analysis (168 participants, IG=56, CG=105) resulted in a mean difference of 3.13 (95% CI 1.07-5.18, p=0.003) between the groups, amounting to a moderate effect size of d=0.51.

CONCLUSION

A complex, nurse-led intervention, implemented as a collaborative care model, increased perceived self-efficacy in patients with symptoms of anxiety, depression or somatisation compare to control patients. For the first time in the German healthcare system, the SMADS trial validated the belief that a nurse can successfully complement the work of a general practitioner - particularly in supporting self-management of patients with psychosomatic symptoms and their psychosocial needs.

Analysis of recruitment in a pragmatic observational study on C-reactive protein point-of-care testing in primary care

INTRODUCTION

Failure to recruit all eligible study patients can lead to biased results. Little is known on selective patient recruitment in studies on implementation of diagnostic devices.

OBJECTIVES

The aim of this observational study was to measure recruitment of patients in an implementation study in primary care on use of point-of-care (POC) C-reactive protein (CRP) and to evaluate recruitment bias and its impact on the study endpoint.

METHODS

In a cross-sectional observational study on POC CRP implementation and related antibiotics prescribing, we compared included patients with all eligible patients to assess the representativeness of the included subjects. Eligible patients were adults presenting with acute cough in primary care between March and September 2012. The frequency of POC CRP testing and the proportion of prescribed antibiotics were compared between recruited and non-recruited patients. As measure of bias, odds ratios (ORs) with accompanying 95% confidence intervals (CIs) for the association between CRP level (<20 mg/l or not) and antibiotic prescribing were computed.

RESULTS

Of all 1473 eligible patients 348 (24%) were recruited. In recruited patients, POC CRP tests were conducted and antibiotics prescribed more frequently as compared to non-recruited patients (81% versus 6% and 44% versus 29%, respectively). The ORs were 18.2 (95%CI: 9.6-34.3), 30.5 (95%CI: 13.2-70.3) and 3.8 (95%CI: 0.9-14.8) respectively in all eligible patients, the recruited and the non-recruited patients.

CONCLUSION

Selective recruitment resulted in an overestimation of POC CRP test use and antibiotic prescribing.

Preventing and Lessening Exacerbations of Asthma in School-aged children Associated with a New Term (PLEASANT): Recruiting Primary Care Research Sites-the PLEASANT experience

BACKGROUND

Recruitment of general practices and their patients into research studies is frequently reported as a challenge. The Preventing and Lessening Exacerbations of Asthma in School-aged children Associated with a New Term (PLEASANT) trial recruited 142 general practices, across England and Wales and delivered the study intervention to time and target.

AIMS

To describe the process of recruitment used within the cluster randomised PLEASANT trial and present results on factors that influenced recruitment.

METHODS

Data were collected on the number of and types of contact used to gain expression of interest and subsequent randomisation into the PLEASANT trial. Practice size and previous research experience were also collected.

RESULTS

The mean number of contacts required to gain expression of interest were m=3.01 (s.d. 1.6) and total number of contacts from initial invitation to randomisation m=6.8 (s.d. 3.5). Previous randomised controlled trial involvement (hazard ratio (HR)=1.81 (confidence interval (CI) 95%, 1.55-2.11) P<0.001) and number of studies a practice had previously engaged in (odds ratio (OR) 1.91 (CI 95%, (1.52-2.42)) P<0.001), significantly influenced whether a practice would participate in PLEASANT. Practice size was not a significant deciding factor (OR=1.04 (95% CI 0.99-1.08) P=0.137).

CONCLUSIONS

Recruitment to time and target can be achieved in general practice. The amount of resource required for site recruitment should not, however, be underestimated and multiple strategies for contacting practices should be considered. General practitioners with more research experience are more likely to participate in studies.

Changing non-participation in epidemiological studies of older people: evidence from the Cognitive Function and Ageing Study I and II

Background: non-participation in epidemiological studies threatens the generalisability of findings.

Objective: to investigate the change in non-participation between the Medical Research Council Cognitive Function and Ageing Study (CFAS) I and II.

Design: a comparison of two epidemiological studies of older people using identical methods.

Setting: three geographical areas of the United Kingdom.

Subjects: older people aged 65 years and over.

Methods: the two studies were conducted approximately two decades apart between 1989 and 1994 (CFAS I) and between 2008 and 2011 (CFAS II). Random samples were drawn from primary care lists. We compared demographic factors associated with non-participation.

Results: non-participation in CFAS II was higher than in CFAS I (45.3 versus 18.3%). After adjustment for confounders, in both CFAS I and CFAS II, women were more likely to decline to take part (CFAS I: odds ratio (OR) 1.3 95% confidence interval (CI) 1.2 to 1.4; CFAS II: 1.1 95% CI 1.1 to 1.2). Deprivation was associated with non-participation in both studies (highest versus lowest Townsend deprivation quintile, CFAS I: OR 1.4 95% CI 1.2 to 1.6; CFAS II: 2.0 95% CI 1.8 to 2.2). Age was not associated with non-participation in either study (CFAS I, P = 0.21; CFAS II, P = 0.47).

Conclusions: non-participation in epidemiological studies of older people has increased substantially in the past two decades and public willingness to take part in studies of this kind would appear to be declining. As communities become more diverse and older people have increasing commitments on their time, new ways to engage prospective participants are urgently needed.

Effectiveness of monetary incentives to recruit family physicians as study subjects: a randomized controlled trial

Background

Recruiting family physicians to participate as subjects of clinical studies is challenging. Monetary incentives are often used to increase enrolment, but few studies have measured the impact of doing so. As part of a trial seeking to compare two formats of interactive activities within an online continuing medical education (CME) program, we compared family physicians’ recruitment rates with and without a monetary incentive. Recruitment took place by email.

Methods

Family physicians listed in the directory of the College of Physicians of the Province of Quebec (Canada) were emailed a one-page letter inviting them to participate in a randomized trial designed to evaluate a three-hour online CME program on rheumatology. Half of physicians were randomly allocated to receive a version of the letter that offered them $300 to participate (incentive group); the other half was not offered compensation (no-incentive group).

Results

A total of 1314 (91%) physicians had a valid email address as listed in the directory. The response rate was 7.5% (54/724) in the incentive group and 2.6% (19/724) in the no-incentive group (absolute difference [AD] 4.8%, 95% confidence interval [95% CI] = 2.6 – 7.2%; risk ratio [RR] 2.8, 95% CI = 1.7 - 4.7). Recruitment rates were 3.5% (25/724) in the incentive group and 0.6% (4/724) in the no-incentive group (AD 2.9%, 95% CI = 1.5 - 4.5%; RR 6.3, 95% CI = 2.2 - 17.9).

Conclusions

Monetary incentives significantly increased recruitment, which nonetheless remained low. To reach recruitment targets, researchers are advised to plan for an extensive list of email contacts and to minimize restrictive eligibility criteria.

Engagement, recruitment, and retention in a trans-community, randomized controlled trial for the prevention of obesity in rural American Indian and Hispanic children

Engagement, recruitment and retention of participants are critical to the success of research studies but specific strategies are rarely elucidated in the literature. The purpose of this paper is to describe the engagement, recruitment and retention process and outcomes in the Child Health Initiative for Lifelong Eating and Exercise (CHILE) study, and to describe lessons learned in the process. CHILE is a multi-level, group randomized controlled trial of a childhood obesity prevention intervention in rural American Indian and predominantly Hispanic Head Start (HS) centers in New Mexico. Barriers to engagement, recruitment and retention included distrust of researchers, long travel distances, and different HS and community structures. CHILE employed multiple strategies from the onset including the use of formative assessment, building on previous relationships, developing Memoranda of Agreement, using a community engagement specialist, and gaining support of a community champion. As a result of lessons learned, additional strategies were employed, including more frequent feedback to intervention sites, revised permission forms, telephone reminders, increased site visits and over-scheduling of interviews. These strategies resulted in the recruitment of 16 HS centers, 1,879 children, 655 parents, 7 grocery stores and 14 healthcare providers, meeting or exceeding recruitment goals. By combining principles of community engagement, a variety of recruitment strategies, and lessons learned, this study obtained a high level of recruitment and retention.

Engaging traditional medicine providers in colorectal cancer screening education in a chinese american community: a pilot study

INTRODUCTION

Although colorectal cancer (CRC) screening is effective in preventing colon cancer, it remains underused by Asian Americans. Because Chinese Americans often use traditional Chinese medicine (TCM), we conducted a pilot study to explore the feasibility and acceptability of having TCM providers deliver education about CRC screening.

METHODS

Four TCM providers (2 herbalists and 2 acupuncturists) were trained to deliver small-group educational sessions to promote CRC screening. Each provider recruited 15 participants aged 50 to 75. Participants completed a baseline survey on CRC-related knowledge, attitudes, and behaviors and then attended one 2-hour educational session delivered by the providers in Cantonese or Mandarin. Three months later, participants completed a postintervention survey.

RESULTS

Sixty participants were recruited from the San Francisco Chinatown neighborhood. The average age was 62.4 years. Most participants had limited English proficiency (96.7%), annual household income less than $20,000 per year (60%), and low educational attainment (65.1% < high school education). At postintervention (n = 57), significant increases were found in having heard of CRC (from 52.6% to 79.0%, P < .001) and colon polyps (from 64.9% to 84.2%, P < .001). Knowledge regarding screening frequency recommendations also increased significantly. The rate of ever having received any CRC screening test increased from 71.9% to 82.5% (P <.001). The rate of up-to-date screening increased from 70.2% to 79.0% (P = .04).

CONCLUSION

The findings suggest that TCM providers can be trained to deliver culturally and linguistically appropriate outreach on CRC screening within their community. Participants reached by TCM providers increased CRC knowledge and self-reported CRC screening.

Successful recruitment methods in the community for a two-site clinical trial

Effective screening and recruitment are essential to the success of randomized clinical trials. This report is to describe key screening and recruitment strategies in a two site randomized clinical trial (RCT) conducted in community settings with a vulnerable chronically ill population and to suggest valuable approaches when planning trials. Differences between sites in a complex study with two considerably different environments (academic versus home care) and their participant pools presented challenges which required different screening and recruitment methods. A high level of communication between sites, creative problem solving and the ability to be flexible when problems were encountered were needed for successful screening and recruitment.

Gaining information about home visits in primary care: methodological issues from a feasibility study

Background

Home visits are part of general practice work in Germany. Within the context of an expanding elderly population and a decreasing number of general practitioner (GPs), open questions regarding the organisation and adequacy of GPs’ care in immobile patients remain. To answer these questions, we will conduct a representative primary data collection concerning contents and organisation of GPs’ home visits in 2014. Because this study will require considerable efforts for documentation and thus substantial involvement by participating GPs, we conducted a pilot study to see whether such a study design was feasible.

Methods

We used a mixed methods design with two study arms in a sample of teaching GPs of the University Halle. The quantitative arm evaluates participating GPs and documentation of home visits. The qualitative arm focuses on reasons for non-participation for GPs who declined to take part in the pilot study.

Results

Our study confirms previously observed reasons for non-response of GPs in the particular setting of home visits including lack of time and/or interest. In contrast to previous findings, monetary incentives were not crucial for GPs participation. Several factors influenced the documentation rate of home visits and resulted in a discrepancy between the numbers of home visits documented versus those actually conducted. The most frequently reported problem was related to obtaining patient consent, especially when patients were unable to provide informed consent due to cognitive deficits.

Conclusions

The results of our feasibility study provide evidence for improvement of the study design and study instruments to effectively conduct a documentation-intensive study of GPs doing home visits. Improvement of instructions and questionnaire regarding time variables and assessment of the need for home visits will be carried out to increase the reliability of future data. One particularly important methodological issue yet to be resolved is how to increase the representativeness of home visit care by including the homebound patient population that is unable to provide informed consent.

What does it take to deliver an international neurosurgical trial? Experiences from STICH II

BACKGROUND AND PURPOSE

When undertaking multicentre randomised controlled trials some obstacles cause a slower than required recruitment rate. This article discusses factors that affected the completion of the international neurosurgical trial STICH II, which took almost 6 years.

METHODS

We reviewed the following factors: recruitment of participating sites, patient recruitment, patient screening, trial fatigue and maintenance of profile and maintenance of quality and standards. We discuss the practical strategies employed by the STICH II team to address these factors and optimise patient recruitment.

CONCLUSION

Although STICH II attained its final recruitment target, it took longer to complete than anticipated. Publishing and sharing the experiences of the STICH II trial team is an important step towards ensuring that other potential neurosurgical triallists are aware of the issues that can slow patient recruitment and strategies that can help to overcome them.

Research in general practice: a survey of incentives and disincentives for research participation

Background Recruitment rates of general practitioners (GPs) to do research vary widely. This may be related to the ability of a study to incorporate incentives for GPs and minimise barriers to participation. Method A convenience sample of 30 GPs, ten each from the Sydney intervention and control groups Ageing in General Practice 'Detection and Management of Dementia' project (GP project) and 10 GPs who had refused participation, were recruited to determine incentives and barriers to participating in research. GPs completed the 11-item 'Meeting the challenges of research in general practice: general practitioner questionnaire' (GP survey) between months 15 and 24 of the GP project, and received brief qualitative interviews from a research GP to clarify responses where possible. Results The most important incentives the 30 GPs gave for participating in the project were a desire to update knowledge (endorsed by 70%), to help patients (70%), and altruism (60%). Lack of time (43%) was the main barrier. GPs also commented on excessive paperwork and an inadequate explanation of research. Conclusions While a desire to update knowledge and help patients as well as altruism were incentives, time burden was the primary barrier and was likely related to extensive paperwork. Future recruitment may be improved by minimising time burden, making studies simpler with online data entry, offering remuneration and using a GP recruiter.

The broad spectrum of unbearable suffering in end-of-life cancer studied in dutch primary care

BACKGROUND

Unbearable suffering most frequently is reported in end-of-life cancer patients in primary care. However, research seldom addresses unbearable suffering. The aim of this study was to comprehensively investigate the various aspects of unbearable suffering in end-of-life cancer patients cared for in primary care.

METHODS

Forty four general practitioners recruited end-of-life cancer patients with an estimated life expectancy of half a year or shorter. The inclusion period was three years, follow-up lasted one additional year. Practices were monitored bimonthly to identify new cases. Unbearable aspects in five domains and overall unbearable suffering were quantitatively assessed (5-point scale) through patient interviews every two months with a comprehensive instrument. Scores of 4 (serious) or 5 (hardly can be worse) were defined unbearable. The last interviews before death were analyzed. Sources providing strength to bear suffering were identified through additional open-ended questions.

RESULTS

Seventy six out of 148 patients (51%) requested to participate consented; the attrition rate was 8%, while 8% were alive at the end of follow-up. Sixty four patients were followed up until death; in 60 patients interviews were complete. Overall unbearable suffering occurred in 28%. A mean of 18 unbearable aspects was present in patients with serious (score 4) overall unbearable suffering. Overall, half of the unbearable aspects involved the domain of traditional medical symptoms. The most frequent unbearable aspects were weakness, general discomfort, tiredness, pain, loss of appetite and not sleeping well (25%-57%). The other half of the unbearable aspects involved the domains of function, personhood, environment, and nature and prognosis of disease. The most frequent unbearable aspects were impaired activities, feeling dependent, help needed with housekeeping, not being able to do important things, trouble accepting the situation, being bedridden and loss of control (27%-55%). The combination of love and support was the most frequent source (67%) providing strength to bear suffering.

CONCLUSIONS

Overall unbearable suffering occurred in one in every four end-of-life cancer patients. Half of the unbearable aspects involved medical symptoms, the other half concerned psychological, social and existential dimensions. Physicians need to comprehensively assess suffering and provide psychosocial interventions alongside physical symptom management.

How do French GPs consider participating in primary care research: the DRIM study

BACKGROUND

Recruiting GPs is an issue faced by most research teams in primary care.

OBJECTIVES

To assess GPs' willingness and expectations with regard to research in French primary care and to identify factors that may increase their participation in research projects.

METHODS

Cross-sectional study conducted with a representative sample of 452 GPs from the Rhone-Alpes region in France.

RESULTS

Among 284 GPs (63%) who participated, 85 [29.9%, 95% confidence interval (CI) = 26.4-35.3%] were willing to participate in research as investigators and 83 (29.2%, 95% CI: 23.9-34.5%) had already participated in research projects. Multivariate analysis showed that an earlier participation in research projects [odds ratio (OR) = 3.3], a training practice (OR = 2.3), membership in a research network (OR = 2.1) and younger age (OR = 1.9 for 10 years less) were associated with the willingness to participate in future research projects. Whereas 55% of practitioners who already had an experience in research had participated in a therapeutic trial, those willing to participate in the future preferred to participate in descriptive (26%) or etiologic (22%) studies. Preventive, diagnostic and therapeutic procedures and quality of care were the domains, which interested GPs most. The most expected clinical themes concerned cardiovascular, metabolic, musculoskeletal and respiratory problems.

CONCLUSIONS

To meet the expectations of French GPs willing to participate in primary care research, it is advisable to diversify studies with respect to their types, domains and themes. Linkage to universities and research networks should also be encouraged.

Recruitment difficulties in a primary care cluster randomised trial: investigating factors contributing to general practitioners' recruitment of patients

Background

Recruitment of patients by health professionals is reported as one of the most challenging steps when undertaking studies in primary care settings. Numerous investigations of the barriers to patient recruitment in trials which recruit patients to receive an intervention have been published. However, we are not aware of any studies that have reported on the recruitment barriers as perceived by health professionals to recruiting patients into cluster randomised trials where patients do not directly receive an intervention. This particular subtype of cluster trial is commonly termed a professional-cluster trial. The aim of this study was to investigate factors that contributed to general practitioners recruitment of patients in a professional-cluster trial which evaluated the effectiveness of an intervention to increase general practitioners adherence to a clinical practice guideline for acute low-back pain.

Method

General practitioners enrolled in the study were posted a questionnaire, consisting of quantitative items and an open-ended question, to assess possible reasons for poor patient recruitment. Descriptive statistics were used to summarise quantitative items and responses to the open-ended question were coded into categories.

Results

Seventy-nine general practitioners completed at least one item (79/94 = 84%), representing 68 practices (85% practice response rate), and 44 provided a response to the open-ended question. General practitioners recalled inviting a median of two patients with acute low-back pain to participate in the trial over a seven-month period; they reported that they intended to recruit patients, but forgot to approach patients to participate; and they did not perceive that patients had a strong interest or disinterest in participating. Additional open-ended comments were generally consistent with the quantitative data.

Conclusion

A number of barriers to the recruitment of patients with acute low-back pain by general practitioners in a professional-cluster trial were identified. These barriers were similar to those that have been identified in the literature surrounding the recruitment of patients in individual patient randomised trials. To advance the evidence base for patient recruitment strategies in primary care settings, trialists undertaking professional-cluster trials need to develop and evaluate patient recruitment strategies that minimise the efforts required by practice staff to recruit patients, while also meeting privacy and ethical responsibilities and minimising the risk of selection bias.

Factors that promote and prohibit access to participants in the clinical setting: a review of response rates from a health communication intervention study

OBJECTIVE

This report examines the factors that influence researchers' abilities to recruit participants into health communication studies conducted within the clinical setting.

METHOD

Review of response rates over a 15 month data collection period for an intervention study on patient-physician communication, low health literacy, and diabetes management.

RESULTS

Most patients were willing to participate (73%). The challenge was not fostering interest in the study, but rather being able to approach potential participants. Over the course of the study, patients with diabetes visited the clinic 1263 times yet interviewers were only able to approach patients 196 times for potential inclusion in the study. Confounding factors that affected recruiting participants included the interviewers' availability and clinic schedule, as well as patient chief complaint and no show or rescheduling rates.

CONCLUSION

Researchers must engage in collaborative efforts with clinic staff during the research design phase, maximize their availability to approach potential patients, and capitalize on the insights of clinic staff to approach those patients who fit the study criteria and would be most willing to participate in the research project.

PRACTICE IMPLICATIONS

Researchers must learn about the clinic, reduce research burden, and be flexible to work within the constraints of the clinic setting.

Recruitment of representative samples for low incidence cancer populations: do registries deliver?

Background

Recruiting large and representative samples of adolescent and young adult (AYA) cancer survivors is important for gaining accurate data regarding the prevalence of unmet needs in this population. This study aimed to describe recruitment rates for AYAs recruited through a cancer registry with particular focus on: active clinician consent protocols, reasons for clinicians not providing consent and the representativeness of the final sample.

Methods

Adolescents and young adults aged 14 to19 years inclusive and listed on the cancer registry from January 1 2002 to December 31 2007 were identified. An active clinician consent protocol was used whereby the registry sent a letter to AYAs primary treating clinicians requesting permission to contact the survivors. The registry then sent survivors who received their clinician's consent a letter seeking permission to forward their contact details to the research team. Consenting AYAs were sent a questionnaire which assessed their unmet needs.

Results

The overall consent rate for AYAs identified as eligible by the registry was 7.8%. Of the 411 potentially eligible survivors identified, just over half (n = 232, 56%) received their clinician's consent to be contacted. Of those 232 AYAs, 65% were unable to be contacted. Only 18 AYAs (7.8%) refused permission for their contact details to be passed on to the research team. Of the 64 young people who agreed to be contacted, 50% (n = 32) completed the questionnaire.

Conclusions

Cancer registries which employ active clinician consent protocols may not be appropriate for recruiting large, representative samples of AYAs diagnosed with cancer. Given that AYA cancer survivors are highly mobile, alternative methods such as treatment centre and clinic based recruitment may need to be considered.

Qualitative research ethics: enhancing evidence-based practice in physical therapy

BACKGROUND

Increasing challenges to health care systems and the prominence of patient-centered care and evidence-based practice have fostered the application of qualitative approaches in health care settings, prompting discussions of associated ethical issues in a range of disciplines.

OBJECTIVES

The purposes of this work were to identify and describe the application and value of qualitative health research for physical therapy and to identify ethical considerations in a qualitative research study.

DESIGN

This was a qualitative interview study with telephone follow-ups.

METHODS

Forty-six participants were interviewed about their early experiences with rheumatoid arthritis. They also were asked what motivated them to volunteer for the study. To inform the discussion of ethics in qualitative health research, this study drew on the in-depth interviews, took a descriptive approach to the data, and applied the traditional ethical principles of autonomy, justice, and beneficence to the study process.

RESULTS

Ethical issues emerged in this qualitative health research study that were both similar to and different from those that exist in a positivist paradigm (eg, clinical research). With flexibility and latitude, the traditional principle approach can be applied usefully to qualitative health research.

CONCLUSIONS

These findings build on previous research and discussion in physical therapy and other disciplines that urge a flexible approach to qualitative research ethics and recognize that ethics are embedded in an unfolding research process involving the role of the subjective researcher and an active participant. We suggest reflexivity as a way to recognize ethical moments throughout qualitative research and to help build methodological and ethical rigor in research relevant to physical therapist practice.
