Pediatricians' attitudes toward randomized controlled trials involving children

Turkish Pediatrician Beliefs About Third-hand Smoking

INTRODUCTION

Although third-hand smoke (THS) is a relatively new concept, it emerges as an important health problem. This study evaluated the beliefs of Turkish Pediatricians about THS.

METHOD

The survey, designed to be self-filled by pediatricians, provided information on demographic data, lifestyle factors, and beliefs about THS. Participant beliefs about THS were evaluated using the Beliefs About Third-Hand Smoke scale. This study was conducted by applying a web-based survey to pediatricians in Turkey.

RESULTS

The Beliefs About Third-Hand Smoke scale scores were lower in participants who were male (odds ratio [OR] = 1.479; 95% confidence interval [CI], 0.246-0.526; p < .001), have children (OR = 0.656; 95% CI, 0.156-0.665; p = .002), widowed/separated (OR = 0.498; 95% CI, -1.072 to -0.360; p < .001), a smoker (OR = 0.586; 95% CI, -0.711 to -0.355; p < .001), worked in State Hospital (OR = 0.574; 95% CI, -0.768 to -0.423; p < .001), and specialists (OR = 0.621; 95% CI, -0.608 to -0.207; p < .001).

DISCUSSION

This study showed that pediatricians who were male, widowed/separated, a smoker, with children, working in a State Hospital, and specialists had less belief in the side effects of THS.

The effectiveness and acceptability of multimedia information when recruiting children and young people to trials: the TRECA meta-analysis of SWATs

Background

The information provided to potential trial participants plays a crucial role in their decision-making. Printed participant information sheets for trials have received recurrent criticism as being too long and technical, unappealing and hard to navigate. An alternative is to provide information through multimedia (text, animations, video, audio, diagrams and photos). However, there is limited evidence on the effects of multimedia participant information on research recruitment rates, particularly in children and young people.

Objectives

The study objectives were as follows: 1. to develop template multimedia information resources through participatory design, for use when recruiting children and young people to trials 2. to evaluate the multimedia information resources in a series of Studies Within A Trial, to test their effects on recruitment and retention rates, and participant decision-making, by comparing the provision of multimedia information resources instead of printed participant information sheets, and comparing the provision of multimedia information resources in addition to printed participant information sheets.

Design

Two-phase study: 1. multimedia information resources development including qualitative study; user testing study; readability metrics; enhanced patient and public involvement 2. multimedia information resources' evaluation comprising Studies Within A Trial undertaken within host trials recruiting children and young people.

Setting

United Kingdom trials involving patients aged under 18.

Participants

Development phase: n = 120 (children and young people, parents, clinicians, trial personnel). Evaluation phase: n = 1906 (children and young people being asked to take part in trials).

Interventions

Multimedia information resources (comprising text, audio, 'talking heads' video, trial-specific and trial-generic animations). Printed participant information sheets.

Main outcome measures

Primary outcome: trial recruitment rate comparing multimedia information resource-only with printed participant information sheet-only provision. Secondary outcomes: trial recruitment rate comparing combined multimedia information resource and printed participant information sheet with printed participant information sheet-only provision; trial retention rate; quality of participant decision-making. Results for each trial were calculated and combined in a two-stage random-effects meta-analysis.

Results

Phase 1 generated two multimedia information resource templates: (1) for children aged 6-11 years; (2) for children aged 12-18 years and parents. In the Phase 2 Studies Within A Trial the multimedia information resources improved trial recruitment, when compared to printed information alone [odds ratio (OR) = 1.54; 95% confidence interval (CI) 1.05 to 2.28; p = 0.03; I2 = 0%]. When printed participant information sheet-only provision was compared to combined multimedia information resource and printed participant information sheet provision, there was no effect on trial recruitment (OR = 0.89; 95% CI 0.53 to 1.50; I2 = 0%). There were no differences between multimedia information resource and printed participant information sheet on trial retention or participant decision-making quality. In a study within a hypothetical trial setting, multimedia information resource-only provision produced higher ratings of 'information was easy to understand' (Z = 3.03; p = 0.003) and 'I had confidence in decision-making' (Z = 2.00; p = 0.044) than printed participant information sheet-only provision.

Limitations

It was not possible to include data from three Studies Within A Trial in the meta-analysis due to limited sample size, and questionnaire return rates were low, which reduced the strength of the findings.

Conclusions

Use of multimedia information increased the rate of recruitment to trials involving children and young people compared to standard patient information sheets.

Future work

There should be further evaluation of the effects of multimedia information on recruitment to trials involving children and young people. It would be valuable to assess any impacts of multimedia information resources on communication between trial recruiters, children and young people, and parents.

Guardians and research staff experiences and views about the consent process in hospital-based paediatric research studies in urban Malawi: A qualitative study

BACKGROUND

Obtaining consent has become a standard way of respecting the patient's rights and autonomy in clinical research. Ethical guidelines recommend that the child's parent/s or authorised legal guardian provides informed consent for their child's participation. However, obtaining informed consent in paediatric research is challenging. Parents become vulnerable because of stress related to their child's illness. Understanding the views held by guardians and researchers about the consent process in Malawi, where there are limitations in health care access and research literacy will assist in developing appropriate consent guidelines.

METHODS

We conducted 20 in-depth interviews with guardians of children and research staff who had participated in paediatric clinical trial and observational studies in acute and non-acute settings in the Southern Region of Malawi. Interviews were audio-recorded, transcribed verbatim, and thematically analysed. Interviews were compared across studies and settings to identify differences and similarities in participants' views about informed consent processes. Data analysis was facilitated by NVIVO 11 software.

RESULTS

All participants across study types and settings reported that they associated participating in research with therapeutic benefits. Substantial differences were noted in the decision-making process across study settings. Guardians from acute studies felt that the role of their spouses was neglected during consenting, while staff reported that they had problems obtaining consent from guardians when their partners were not present. Across all study types and settings, research staff reported that they emphasised the benefits more than the risks of the study to participants, due to pressure to recruit. Participants from non-acute settings were more likely to recall information shared during the consent process than participants in the acute setting.

CONCLUSION

The health care context, culture and research process influenced participants' understanding of study information across study types and settings. We advise research managers or principal investigators to define minimum requirements that would not compromise the consent process and conduct study specific training for staff. The use of one size fits all consent process may not be ideal. More guidance is needed on how these differences can be incorporated during the consent process to improve understanding and delivery of consent. Trial registration Not applicable.

Establishing and augmenting views on the acceptability of a paediatric critical care randomised controlled trial (the FEVER trial): a mixed methods study

OBJECTIVE

To explore parent and staff views on the acceptability of a randomised controlled trial investigating temperature thresholds for antipyretic intervention in critically ill children with fever and infection (the FEVER trial) during a multi-phase pilot study.

DESIGN

Mixed methods study with data collected at three time points: (1) before, (2) during and (3) after a pilot trial.

SETTING

English, Paediatric Intensive Care Units (PICUs).

PARTICIPANTS

(1) Pre-pilot trial focus groups with pilot site staff (n=56) and interviews with parents (n=25) whose child had been admitted to PICU in the last 3 years with a fever and suspected infection, (2) Questionnaires with parents of randomised children following pilot trial recruitment (n=48 from 47 families) and (3) post-pilot trial interviews with parents (n=19), focus groups (n=50) and a survey (n=48) with site staff. Analysis drew on Sekhon et al's theoretical framework of acceptability.

RESULTS

There was initial support for the trial, yet some held concerns regarding the proposed temperature thresholds and not using paracetamol for pain or discomfort. Pre-trial findings informed protocol changes and training, which influenced views on trial acceptability. Staff trained by the FEVER team found the trial more acceptable than those trained by colleagues. Parents and staff found the trial acceptable. Some concerns about pain or discomfort during weaning from ventilation remained.

CONCLUSIONS

Pre-trial findings and pilot trial experience influenced acceptability, providing insight into how challenges may be overcome. We present an adapted theoretical framework of acceptability to inform future trial feasibility studies.

Different corticosteroid induction regimens in children and young people with juvenile idiopathic arthritis: the SIRJIA mixed-methods feasibility study

BACKGROUND

In the UK, juvenile idiopathic arthritis is the most common inflammatory disorder in childhood, affecting 10 : 100,000 children and young people aged < 16 years each year, with a population prevalence of around 1 : 1000. Corticosteroids are commonly used to treat juvenile idiopathic arthritis; however, there is currently a lack of consensus as to which corticosteroid induction regimen should be used with various disease subtypes and severities of juvenile idiopathic arthritis.

OBJECTIVE

The main study objective was to determine the feasibility of conducting a randomised controlled trial to compare the different corticosteroid induction regimens in children and young people with juvenile idiopathic arthritis.

DESIGN

This was a mixed-methods study. Work packages included a literature review; qualitative interviews with children and young people with juvenile idiopathic arthritis and their families; a questionnaire survey and screening log to establish current UK practice; a consensus meeting with health-care professionals, children and young people with juvenile idiopathic arthritis, and their families to establish the primary outcome; a feasibility study to pilot data capture and to collect data for future sample size calculations; and a final consensus meeting to establish the final protocol.

SETTING

The setting was rheumatology clinics across the UK.

PARTICIPANTS

Children, young people and their families who attended clinics and health-care professionals took part in this mixed-methods study.

INTERVENTIONS

This study observed methods of prescribing corticosteroids across the UK.

MAIN OUTCOME MEASURES

The main study outcomes were the acceptability of a future trial for children, young people, their families and health-care professionals, and the feasibility of delivering such a trial.

RESULTS

Qualitative interviews identified differences in the views of children, young people and their families on a randomised controlled trial and potential barriers to recruitment. A total of 297 participants were screened from 13 centres in just less than 6 months. In practice, all routes of corticosteroid administration were used, and in all subtypes of juvenile idiopathic arthritis. Intra-articular corticosteroid injection was the most common treatment. The questionnaire surveys showed the varying clinical practice across the UK, but established intra-articular corticosteroids as the treatment control for a future trial. The primary outcome of choice for children, young people, their families and health-care professionals was the Juvenile Arthritis Disease Activity Score, 71-joint count. However, results from the feasibility study showed that, owing to missing blood test data, the clinical Juvenile Arthritis Disease Activity Score should be used. The Juvenile Arthritis Disease Activity Score, 71-joint count, and the clinical Juvenile Arthritis Disease Activity Score are composite disease activity scoring systems for juvenile arthritis. Two final trial protocols were established for a future randomised controlled trial.

LIMITATIONS

Fewer clinics were included in this feasibility study than originally planned, limiting the ability to draw strong conclusions about these units to take part in future research.

CONCLUSIONS

A definitive randomised controlled trial is likely to be feasible based on the findings from this study; however, important recommendations should be taken into account when planning such a trial.

FUTURE WORK

This mixed-methods study has laid down the foundations to develop the evidence base in this area and conducting a randomised control trial to compare different corticosteroid induction regimens in children and young people with juvenile idiopathic arthritis is likely to be feasible.

Protective parents and permissive children: what qualitative interviews with parents and children can tell us about the feasibility of juvenile idiopathic arthritis trials

BACKGROUND

Patient recruitment can be very challenging in paediatric studies, especially in relatively uncommon conditions, such as juvenile idiopathic arthritis (JIA). However, involving children and young people (CYP) in the design of such trials could promise a more rapid trajectory towards making evidence-based treatments available. Studies involving CYP are advocated in the literature but we are not aware of any early stage feasibility studies that have qualitatively accessed the perspectives of parents and CYP with a long term condition to inform design and conduct of a trial. In the context of a feasibility study to inform the design of a proposed randomised controlled trial of corticosteroid induction regimen in JIA, we explored families' perspectives on the proposed trial and on JIA trials generally.

METHODS

We analysed interviews with 27 participants (8 CYP aged 8-16 years and 19 parents) from four UK paediatric rheumatology centres. CYP had recently received corticosteroids to treat JIA. Audio-recorded interviews were transcribed and analysed thematically, drawing on the Framework Method.

RESULTS

Both parents and CYP were capable of engaging with the logic of the proposed trial but pointed to challenges with its design. Treatment preferences influenced willingness to participate in the proposed trial. The preferences of older children and their parents often differed, with CYP being more willing to participate in the proposed trial than parents. Families' current treatment preferences were largely informed by past positive and negative treatment experiences. Some participants also indicated that their treatment preferences were influenced by those of their clinicians.

CONCLUSION

Previous research has typically focused on deficits in patients' understandings of trials. We found that both parents and CYP understood trial concepts and were able to identify potential flaws in the proposed trial. We propose recommendations to optimise the design of a planned corticosteroid induction regimen trial in JIA. Accessing both parents' and CYP's perspectives helps to identify and address recruitment challenges, which will ultimately optimise informed consent and future recruitment.

Polyethylene Glycol Maintenance Treatment for Childhood Functional Constipation: A Randomized, Placebo-controlled Trial

OBJECTIVE

The aim of this study was to investigate the long-term efficacy of polyethylene glycol (PEG) during maintenance treatment of childhood functional constipation (FC) in a randomized, double-blinded, placebo-controlled trial.

METHODS

Children (2-16 years) with FC according to the Rome III criteria were randomly assigned to maintenance treatment with PEG or placebo for 24 weeks. Children reporting treatment failure before 24 weeks were switched to conventional treatment. Primary outcome was successful treatment, defined as absence of any Rome III criteria with or without use of medication after 24 weeks.

RESULTS

A total of 102 children were included: PEG/placebo: 49/53. At 24 weeks, significantly more patients in the PEG group, compared to the placebo group, were successfully treated (33 [67%] vs 19 [36%] hazard ratio (95% confidence intervals) = 3.21 [1.73-5.94]). Significantly fewer children in the PEG group switched to rescue medication (2 [4%] vs 30 [57%], P < 0.001). Time before the change to rescue medication was 13 and 27 days, respectively, for each of the 2 children in the PEG group who required rescue medication. Median time to shift to rescue medication was 27 days (range: 3-64 days) in the placebo group. At 24 weeks after initiation of treatment, 33 children (67%) in the PEG group were successfully treated, compared to 19 children (32%) in the placebo group (hazard ratio (95% confidence intervals) = 3.21 [1.73-5.94]). No serious adverse event related to use of the medication was registered.

CONCLUSIONS

Maintenance treatment with PEG is significantly more effective than placebo in preventing relapse of constipation symptoms during long-term maintenance treatment in childhood FC. We therefore recommend that maintenance treatment commence after disimpaction.

Design and Reporting Characteristics of Clinical Trials of Select Chronic and Recurrent Pediatric Pain Conditions: An Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks Systematic Review

Fewer randomized clinical trials (RCTs) are conducted for chronic or recurrent pain in pediatric populations compared with adult populations; thus, data to support treatment efficacy in children are limited. This article evaluates the design features and reporting practices of RCTs for chronic and recurrent pain that are likely unique to, or particularly important in, a pediatric population to promote improvements in the evidence base for pediatric pain treatments. Areas covered include outcome measure selection and reporting and reporting of adverse events and challenges to recruitment and retention. A search of PubMed and EMBASE identified primary publications describing RCTs of treatments for select chronic and recurrent pain conditions in children or adolescents published between 2000 and 2017. Only 49% of articles identified a primary outcome measure. The primary outcome measure assessed pain intensity in 38% of the trials, specifically measure by verbal rating scale (13%), faces pain scale (11%), visual analogue scale (9%), or numeric rating scale (5%). All of the CONSORT harms reporting recommendations were fulfilled by <50% of the articles. Discussions of recruitment challenges occurred in 64% of articles that enrolled <90% of their target sample. However, discussions regarding retention challenges only occurred in 14% of trials in which withdrawal rates were >10%. The goal of this article is to promote comprehensive reporting of pediatric pain RCTs to improve the design of future trials, facilitate conduction of systematic reviews and meta-analyses, and better inform clinical practice. PERSPECTIVE: This review of chronic and recurrent pediatric pain trials demonstrates inadequacies in the reporting quality of key features specifically important to pediatric populations. It provides recommendations that address these shortcomings to promote continued efforts toward improving the quality of the design and publication of future pediatric clinical pain trials.

Perceived barriers to pediatrician and family practitioner participation in pediatric clinical trials: Findings from the Clinical Trials Transformation Initiative

Despite legislation to stimulate pediatric drug development through clinical trials, enrolling children in trials continues to be challenging. Non-investigator (those who have never served as a clinical trial investigator) providers are essential to recruitment of pediatric patients, but little is known regarding the specific barriers that limit pediatric providers from participating in and referring their patients to clinical trials. We conducted an online survey of pediatric providers from a wide variety of practice types across the United States to evaluate their attitudes and awareness of pediatric clinical trials. Using a 4-point Likert scale, providers described their perception of potential barriers to their practice serving as a site for pediatric clinical trials. Of the 136 providers surveyed, 52/136 (38%) had previously referred a pediatric patient to a trial, and only 17/136 (12%) had ever been an investigator for a pediatric trial. Lack of awareness of existing pediatric trials was a major barrier to patient referral by providers, in addition to consideration of trial risks, distance to the site, and time needed to discuss trial participation with parents. Overall, providers perceived greater challenges related to parental concerns and parent or child logistical barriers than study implementation and ethics or regulatory barriers as barriers to their practice serving as a trial site. Providers who had previously been an investigator for a pediatric trial were less likely to be concerned with potential barriers than non-investigators. Understanding the barriers that limit pediatric providers from collaboration or inhibit their participation is key to designing effective interventions to optimize pediatric trial participation.

Clinical trials: Kids are not just little people

Clinical trials are the backbone of modern evidence-based medicine. They are the vital bridge between research-based discovery and cutting edge patient care. Randomized, controlled clinical trials are the gold standard of medical research, providing a method for evaluation and discovery of novel therapies that improve and even save lives. Despite an increase in the number of pediatric and adult clinical trials over recent decades, this growth has not been equal among these populations. The volume of clinical trials involving children lags substantially behind their adult counterparts. Children are not simply little adults. As a result, extrapolating results from adult clinical trials to the treatment of children may be inappropriate and, possibly, harmful. In this review, we discuss the intricacies of performing clinical trials in all patients and stress the unique distinguishing characteristics of pediatric clinical trials.

Attitudes of small animal practitioners toward participation in veterinary clinical trials

OBJECTIVE To determine attitudes of small animal practitioners toward veterinary clinical trials and variables influencing their likelihood of participating in such trials. DESIGN Cross-sectional survey. SAMPLE Small animal practitioners with membership in 1 of 2 online veterinary communities (n = 163 and 652). PROCEDURES An online survey was developed for each of 2 veterinary communities, and invitations to participate were sent via email. Each survey included questions designed to collect information on the respondents' willingness to enroll their patients in clinical trials and to recommend participation to clients for their pets. RESULTS More than 80% of respondents to each survey indicated that they spend no time in clinical research. A high proportion of respondents were likely or extremely likely to recommend clinical trial participation to clients for their pets when those trials involved treatments licensed in other countries, novel treatments, respected investigators, or sponsoring by academic institutions, among other reasons. Reasons for not recommending participation included distance, time restrictions, and lack of awareness of ongoing clinical trials; 28% of respondents indicated that they did not usually learn about such clinical trials. Most respondents (79% to 92%) rated their recommendation of a trial as important to their client's willingness to participate. CONCLUSIONS AND CLINICAL RELEVANCE Participation in veterinary clinical trials by small animal practitioners and their clients and patients appeared low. Efforts should be increased to raise practitioner awareness of clinical trials for which patients might qualify. Specific elements of trial design were identified that could be modified to increase participation.

Developing and evaluating multimedia information resources to improve engagement of children, adolescents, and their parents with trials (TRECA study): Study protocol for a series of linked randomised controlled trials

Background

Randomised controlled trials are widely established as the best method for testing health interventions whilst minimising bias. However, recruitment and subsequent retention of children and adolescents in healthcare trials is challenging. Participant information sheets are often lengthy and difficult to read and understand. Presenting key information using multimedia may help to overcome these limitations and better support young people and their parents in deciding whether to participate in a clinical trial.

Methods

The TRECA (TRials Engagement in Children and Adolescents) study has two phases. The first phase involves a qualitative study with children and adolescents and their parents to inform the development of multimedia information resources and iterative user testing to refine the resources. The second phase will embed the use of the multimedia information resources into six host trials in the United Kingdom. Patients and parents approached to participate in the host trials will be randomly allocated to either use the multimedia information resource in conjunction with standard participant information sheets, the multimedia information resource alone, or the standard participant information sheets alone. The primary outcome will be the effect of the multimedia information resources on recruitment into trials. Other outcomes measured include the effect of multimedia information resources on retention of participants into the host trials and the impact on family members’ decision-making processes, when compared to standard participant information sheets alone.

Discussion

This study will inform whether multimedia information resources, when developed using participatory design principles, are able to increase recruitment and retention of children and adolescents into trials. There is also the potential for patients to make better informed decisions through the use of multimedia information resources. The multimedia information resources also have the potential to assist with providing information on other healthcare decisions outside of clinical trials.

Premature Discontinuation of Pediatric Randomized Controlled Trials: A Retrospective Cohort Study

OBJECTIVES

To determine the proportion of pediatric randomized controlled trials (RCTs) that are prematurely discontinued, examine the reasons for discontinuation, and compare the risk for recruitment failure in pediatric and adult RCTs.

STUDY DESIGN

A retrospective cohort study of RCTs approved by 1 of 6 Research Ethics Committees (RECs) in Switzerland, Germany, and Canada between 2000 and 2003. We recorded trial characteristics, trial discontinuation, and reasons for discontinuation from protocols, corresponding publications, REC files, and a survey of trialists.

RESULTS

We included 894 RCTs, of which 86 enrolled children and 808 enrolled adults. Forty percent of the pediatric RCTs and 29% of the adult RCTs were discontinued. Slow recruitment accounted for 56% of pediatric RCT discontinuations and 43% of adult RCT discontinuations. Multivariable logistic regression analyses suggested that pediatric RCT was not an independent risk factor for recruitment failure after adjustment for other potential risk factors (aOR, 1.22; 95% CI, 0.57-2.63). Independent risk factors were acute care setting (aOR, 4.00; 95% CI, 1.72-9.31), nonindustry sponsorship (aOR, 4.45; 95% CI, 2.59-7.65), and smaller planned sample size (aOR, 1.05; 95% CI 1.01-1.09, in decrements of 100 participants).

CONCLUSION

Forty percent of pediatric RCTs were discontinued prematurely, owing predominately to slow recruitment. Enrollment of children was not an independent risk factor for recruitment failure.

Effectiveness of Pelvic Physiotherapy in Children With Functional Constipation Compared With Standard Medical Care

BACKGROUND & AIMS

Functional constipation (FC) is a common childhood problem often related to pelvic floor muscle dysfunction. We compared the effectiveness of pelvic physiotherapy (PPT) vs standard medical care (SMC) in children with FC.

METHODS

We performed a multicenter randomized controlled trial of 53 children (age, 5-16 y) with FC according to the Rome III criteria, at hospitals in The Netherlands from December 2009 to May 2014. Group allocation was concealed using a central computer system. SMC consisted of education, toilet training, and laxatives (n = 26), whereas PPT included SMC plus specific physiotherapeutic interventions (n = 27). Results were obtained from written reports from the subjects' pediatricians and parents. The primary outcome was absence of FC, according to Rome III criteria, after a 6-month follow-up period. Secondary outcomes were global perceived effect (range, 1-9; success was defined as a score ≥ 8), numeric rating scales assessing quality of life (parent and child; scale, 1-10), and the strengths and difficulties questionnaire (SDQ).

RESULTS

Treatment was effective for 92.3% of the children receiving PPT and for 63.0% of the children receiving SMC (adjusted odds ratio for success of PPT, 11.7; 95% confidence interval, 1.8-78.3) (P = .011). Significantly more children undergoing PPT stopped using laxatives (adjusted odds ratio, 6.5; 95% confidence interval, 1.6-26.4) (P = .009). Treatment success (based on global perceived effect) was achieved for 88.5% of subjects receiving PPT vs 33.3% of subjects receiving SMC) (P < .001). PPT also produced larger adjusted mean differences, before vs after treatment, in numeric rating scales to assess quality of life: an increase of 1.8 points for parents (P = .047) and 2.0 points for children (P = .028). Results from the SDQ did not differ significantly between groups (P = .78).

CONCLUSIONS

In a randomized controlled trial of children with FC, PPT was more effective than SMC on all outcomes measured, with the exception of findings from the SDQ. PPT should be considered as a treatment option for FC in children 5-16 years old. Dutch Clinical Trial Registration no: NL30551.068.09.

Investigator-initiated randomized controlled trials in children with epilepsy: Mission impossible?

Objective

In children many antiepileptic drugs (AEDs) are prescribed off‐label due to a lack of well‐designed randomized controlled trials (RCTs). We conducted a multicenter RCT in the Netherlands to compare levetiracetam and valproic acid as monotherapy in children with newly diagnosed epilepsy. After 2 years, we had to stop this investigator‐initiated trial prematurely because the inclusion rate was too low. We analyzed the reasons for this failure, assessed the various issues involved in performing RCTs in children, and now give recommendations for future studies.

Methods

A questionnaire was completed by all investigators involved in the study. It included questions about the motivation to participate and the perceived reasons for recruitment failure. We also studied literature about financial, logistic, legal, and ethical aspects of RCTs in children.

Results

Main reasons for recruitment failure were overestimation of the number of eligible AED‐naive children referred by general pediatricians; personal preferences of investigators for specific antiepileptic drugs; and the extensive administrative load due to extra regulations and guidelines for children. Fundraising for investigator‐initiated trials is difficult and the majority of RCTs concerning AEDs are sponsored by pharmaceutical companies. Involving children requires balancing between protection and participation; the randomization procedure and obtaining informed consent are complex for both children and parents.

Significance

Performing RCTs with AEDs in children is important but complicated by logistic, regulatory, legal, and ethical restrictions. Based on our recent experience, our advice to colleagues who are planning a similar trial would be to perform a feasibility pilot study; to set up intensive collaboration with referring pediatricians; to arrange support of a clinical trials unit and a local research nurse during the complete trial period; and to incorporate the possibility of extending the recruitment period. Major investments, both financially from governmental organizations and in time, are imperative for independent RCTs in children.

Factors influencing parental consent in a hypothetical pediatric vaccine trial in a developing country setting: a questionnaire study

Clinical vaccine trials have been lacking in the pediatric population due to lower consent rate of the parents. We assessed characteristics of the parents, and motives and barriers underlying the decision process. The results of the questionnaire were evaluated by multivariate analysis. Parents who opted in were younger and more often employed than the parents who opted out. The most important motives were receiving detailed information about trial and benefits to human health. The qualified education of medical community and public about the rationale and benefits of trials is essential for opt-in.

A systematic review of discontinued trials suggested that most reasons for recruitment failure were preventable

OBJECTIVE

To collect and classify reported reasons for recruitment failure in discontinued randomized controlled trials (RCTs) and to assess reporting quality.

METHODS

We systematically searched MEDLINE and EMBASE (2010-2014) and a previous cohort of RCTs for published RCTs reporting trial discontinuation due to poor recruitment. Teams of two investigators selected eligible RCTs working independently and extracted information using standardized forms. We used an iterative approach to classify reasons for poor recruitment.

RESULTS

We included 172 RCTs discontinued due to poor recruitment (including 26 conference abstracts and 63 industry-funded RCTs). Of those, 131 (76%) reported one or more reasons for discontinuation due to poor recruitment. We identified 28 different reasons for recruitment failure; most frequently mentioned were overestimation of prevalence of eligible participants and prejudiced views of recruiters and participants on trial interventions. Few RCTs reported relevant details about the recruitment process such as how eligible participants were identified, the number of patients assessed for eligibility, and who actually recruited participants.

CONCLUSION

Our classification could serve as a checklist to assist investigators in the planning of RCTs. Most reasons for recruitment failure seem preventable with a pilot study that applies the planned informed consent procedure.

Educating Parents About Pediatric Research: Children and Clinical Studies Website Qualitative Evaluation

A gap in information about pediatric clinical trials exists, and parents remain uncertain about what is involved in research studies involving children. We aimed to understand parent perspectives about pediatric clinical research after viewing the online Children and Clinical Studies (CaCS) program. Using a qualitative descriptive study design, we conducted focus groups with parents and phone interviews with physicians. Three themes emerged providing approaches to improve parent's understanding of clinical research by including strategies where parents (a) hear from parents like themselves to learn about pediatric research, (b) receive general clinical research information to complement study-specific details, and (c) are provided more information about the role of healthy child volunteers. Parents found the website a valuable tool that would help them make a decision about what it means to participate in research. This tool can assist parents, providers, and researchers by connecting general information with study-specific information.

Barriers to participation in surgical randomized controlled trials in pediatric urology: A qualitative study of key stakeholder perspectives

INTRODUCTION

Randomized controlled trials (RCTs) are considered the gold standard for assessing treatment efficacy. However, pediatric surgical RCTs have been limited in their ability to recruit patients. The purpose of this study was to identify barriers and motivators to pediatric participation in surgical RCTs.

METHODS

We conducted a series of two focus groups with parents and one focus group with urology providers for children aged <2 years of age with a diagnosis of Society for Fetal Urology grade 3 or 4 hydronephrosis. We then administered a survey to referring pediatricians based on the initial analysis of focus group findings. Theme analysis was used for all qualitative transcribed text data obtained from focus groups and open-ended survey questions using team-based inductive approaches. Descriptive statistics were obtained for the remainder of the provider survey.

RESULTS

Using qualitative text from stakeholders (n = 38) we identified four key themes across the data: responsibility to my child; responsibility to my patient; responsibility to the field; and irreversibility of surgery. Participants felt there was an obligation to be informed of relevant scientific research within a clinic research culture. However, there remains a disconnect for parents between randomized research studies that may ultimately benefit their child, depending on their age and concern their child is being treated as a 'guinea pig'. Some parents were willing to participate in RCTs but all were more open to participate in an observational study where the treatment decisions were felt to be under their control even when there was no "right answer" or multiple equivalent options for treatment. There was mixed opinion across the parents and providers whether research trial education and enrollment should be provided by the pediatrician or urologist. Active physician decisions were seen as critical within the context of a long term clinical relationship and provision of information of risks and benefits without pressure were considered essential for ethical research by both parents and providers.

CONCLUSION

While some parents are open to participation in surgical RCTs, providers and parents of children with hydronephrosis feel discomfort with the element of chance in surgical randomized trials. Parents and providers are more likely to participate in observational studies where treatment decisions may be made jointly by the physician and the parent. These findings suggest that pragmatic trial strategies with the option for participation in an observational cohort may improve recruitment of pediatric patients into surgical clinical trials.

Nurses' Attitudes Toward Clinical Research: Experience of the Therapeutic Hypothermia After Pediatric Cardiac Arrest Trials

OBJECTIVES

To understand factors affecting nurses' attitudes toward the Therapeutic Hypothermia After Pediatric Cardiac Arrest trials and association with approach/consent rates.

DESIGN

Cross-sectional survey of pediatric/cardiac intensive care nurses' perceptions of the trials.

SETTING

Study was conducted at 16 of 38 self-selected study sites.

SUBJECTS

Pediatric and cardiac intensive care nurses.

MEASUREMENTS AND MAIN RESULTS

The primary outcome was the proportion of nurses with positive perceptions, as defined by agree or strongly agree with the statement "I am happy to take care of a Therapeutic Hypothermia after Pediatric Cardiac Arrest patient". Associations between perceptions and study approach/consent rates were also explored. Of 2,241 nurses invited, 1,387 (62%) completed the survey and 77% reported positive perceptions of the trials. Nurses, who felt positively about the scientific question, the study team, and training received, were more likely to have positive perceptions of the trials (p < 0.001). Nurses who had previously cared for a research patient had significantly more positive perceptions of Therapeutic Hypothermia After Pediatric Cardiac Arrest compared with those who had not (79% vs 54%; p < 0.001). Of the 754 nurses who cared for a Therapeutic Hypothermia After Pediatric Cardiac Arrest patient, 82% had positive perceptions, despite 86% reporting it required more work. Sixty-nine percent believed that hypothermia reduces brain injury and mortality; sites had lower consent rates when their nurses believed that hypothermia was beneficial. Institution-specific approach rates were positively correlated with nurses' perceptions of institutional support for the trial (r = 0.54; p = 0.04), ICU support (r = 0.61; p = 0.02), and the importance of conducting the trial in children (r = 0.61; p = 0.01).

CONCLUSIONS

The majority of nurses had positive perceptions of the Therapeutic Hypothermia After Pediatric Cardiac Arrest trials. Institutional, colleague, and study team support and training were contributing factors. Despite increased work, nurses remained enthusiastic demonstrating that studies with intensive bedside nursing procedures are feasible. Institutions whose nurses believed hypothermia was beneficial had lower consent rates, suggesting that educating nurses on study rationale and equipoise may enhance study participation.

Surrendering control, or nothing to lose: Parents' preferences about participation in a randomised trial of childhood strabismus surgery

BACKGROUND

Intermittent exotropia is the most common form of divergent strabismus (squint) in children. Evidence regarding its optimum management is limited. A pilot randomised controlled trial has recently been completed (Surgery versus Active Monitoring in Intermittent Exotropia trial) to determine the feasibility of a full randomised controlled trial.

PURPOSE

To identify drivers for and barriers against parents' participation in Surgery versus Active Monitoring in Intermittent Exotropia and to seek their views on information received, the need for randomisation, and enhancing acceptability.

METHODS

Multiple method qualitative study using semi-structured telephone interviews to explore parents' motivations and trial screening logs to provide an indication of common barriers. Exploratory thematic analysis identified key themes.

RESULTS

A total of 48 interviews were conducted (14 participants; 34 non-participants). Barriers included no desire for surgery/preference to 'wait and see', wanting surgery immediately, feeling uncomfortable about 'surrendering control' over decision-making/being managed 'at random', lack of confidence in the effectiveness of surgery, believing the risks outweighed the benefits, and lack of trust. Drivers included desiring surgery, 'nothing to lose', benefits offsetting the risks, and being in a trial would result in better care. Some also mentioned 'doing their bit' for research. Suggestions for enhancing acceptability included allowing choice of treatment group, giving more time for decision-making, expanding on information given, and improving communication. Many felt the necessity of randomisation was adequately explained, but there was some indication that it was misunderstood. Information extracted from the screening logs of 80/89 eligible non-participants indicated the most prevalent barrier was not wanting surgery/preferring to observe (56%), followed by desiring surgery straightaway (15%). Opposition to randomisation/wanting to retain control was recorded in 9% of cases as was the belief that the child's squint was not severe enough to warrant surgery.

LIMITATIONS

Interviews were not audio-recorded. Not all who consented to interview could be contacted, although the response/contact rate was good (48/62). A few parents did not provide reasons for refusing the trial.

CONCLUSION

Opposition to surgery and concerns about surrendering control were common obstacles to participation, whereas parents keen for their child to undergo the operation but happy to defer tended to embrace a 'nothing to lose' attitude. Many non-participants would have consented if allowed to choose group, although most of these would have chosen observation. While most parents felt happy with information given and that randomisation was adequately explained, it is of concern that there may be some misunderstanding, which should be addressed in any trial. These findings will inform future trials in childhood exotropia, for example, consideration of preference arms and improving communication. Lessons learnt from the Surgery versus Active Monitoring in Intermittent Exotropia trial could prove valuable to paediatric and surgical trials generally.

Clinical trials in children

Safety and efficacy data on many medicines used in children are surprisingly scarce. As a result children are sometimes given ineffective medicines or medicines with unknown harmful side effects. Better and more relevant clinical trials in children are needed to increase our knowledge of the effects of medicines and to prevent the delayed or non-use of beneficial therapies. Clinical trials provide reliable evidence of treatment effects by rigorous controlled testing of interventions on human subjects. Paediatric trials are more challenging to conduct than trials in adults because of the paucity of funding, uniqueness of children and particular ethical concerns. Although current regulations and initiatives are improving the scope, quantity and quality of trials in children, there are still deficiencies that need to be addressed to accelerate radically equitable access to evidence-based therapies in children.

Ethics review of pediatric multi-center drug trials

The assessment of safety and efficacy of therapeutics for children and adolescents requires the use of multi-centered designs. However, the need to obtain ethical approval from multiple independent research ethics boards (REBs) presents as a challenge to investigators and sponsors who must consider local requirements while ensuring that the protection of human subjects is consistent across sites. In pediatrics, this requirement is complicated by pediatric-specific ethical concerns such as the acquisition of assent and consent and the need for pediatric expertise to assess the scholarly merit of the proposed research. Efforts to tackle these challenges have focused on the process of ethics review, which will improve efficiency. In addition to improving process, we suggest further research to fill gaps in the evidence base for recommendations and decisions made by REBs, specifically their effectiveness to protect human subjects. Evidence gathered will contribute to the successful development, adoption and implementation of harmonized guidance to apply ethics principles in order to protect children through research rather than from research.

Clinical trials involving cats: what factors affect owner participation?

STUDY RATIONALE

Clinical trials are frequently hindered by difficulties in recruiting eligible participants, increasing the timeline and limiting generalizability of results. In veterinary medicine, where proxy enrollment is required, no studies have detailed what factors influence owner participation in clinical trials involving cats. We aimed to investigate these factors through a survey of owners at first opinion practices.

PROTOCOL

The survey was designed using feedback from a pilot study and input from clinical researchers. Owners were asked demographic questions and whether they would, would not, or were unsure about participating in a clinical trial with their cat. They then ranked the importance and influence of various factors on participation using a five-point Likert-type scale, and incentives from most to least encouraging. A total of 413 surveys were distributed to cat owners at four hospitals, two feline-only and two multi-species; 88.6% were completed. Data for importance and influence factors as well as incentive rankings were analyzed overall, and by hospital type, location and whether owners would consider participating.

FINDINGS

The most influential factors were trust in the organization, benefit to the cat and veterinarian recommendation. Importance and influence factors varied by willingness to participate. Ranked incentives were not significantly different across groups, with 'Free Services' ranked highest.

RELEVANCE

This study provides a first look at what factors influence participation in clinical trials with cats. Given the importance placed in the recommendation of veterinarians, continued work is needed to determine veterinarian-related factors affecting clinical trial participation. The results provide guidance towards improved clinical trial design, promotion and education.

Mothers of babies enrolled in a randomized trial immediately after birth report a positive experience

OBJECTIVE

Randomized trials are essential for improving outcomes, but researchers can be hesitant about undertaking clinical trials in newborn babies because of perceived vulnerability of the baby and risk of increasing parental anxiety. There is a paucity of evidence about the parental experience. We investigated mothers' experiences of having their newborn baby participate in a randomized double-blind placebo-controlled trial soon after birth.

STUDY DESIGN

Eligible mothers had consented to their baby's participation in the Sugar Babies Study. Mothers of potentially eligible babies were invited to join the study antenatally, but others were approached postnatally. Babies were enrolled in the study soon after birth and remained in the study for 48 h. After 2 weeks the birth mothers were interviewed by phone about their experience.

RESULT

Four hundred and eighty-one mothers were enrolled, of whom 310 (64%) gave consent antenatally. All mothers were contacted and 477 (99%) were interviewed. The majority of mothers (458, 96%) reported they would consent to participating again, if they had another eligible baby, and 460 mothers (96%) reported they would recommend participation to family and friends. Nineteen mothers (4%) reported they did not like the heel lance blood tests, which were part of routine clinical care and not part of the trial protocol.

CONCLUSION

Most mothers reported the experience of having their newborn baby participate in a clinical trial as positive. Most negative responses were related to aspects of routine care rather than the trial protocol.

Pediatric nephrologists' beliefs regarding randomized controlled trials

BACKGROUND

Pediatrics and pediatric nephrology lag behind adult medicine in producing randomized controlled trials (RCTs). Physician attitudes have been shown to play a significant role in RCT enrollment.

METHODS

We surveyed members of the American Society of Pediatric Nephrology regarding beliefs about RCTs and factors influencing decisions to recommend RCT enrollment. Regression analyses were used to identify the effects of variables on an aggregate score summarizing attitudes toward RCTs.

RESULTS

One hundred thirty replies were received. Sixty-six percent had enrolled patients in RCTs. Respondents in practice for more than 15 years were more likely to have recruited a patient to an RCT than those in practice for less than 5 years. Respondents were more willing to recommend RCT enrollment if the study was multicenter, patients were sicker or had a poorer prognosis, or if the parent or participant received a financial incentive versus the provider. In multiple regression analysis, history of enrolling patients in an RCT was the only significant predictor of higher aggregate RCT-friendly attitude.

CONCLUSIONS

Many pediatric nephrologists have never enrolled a patient in an RCT, particularly those in practice for less than 5 years. Respondents who have not enrolled patients in RCTs have a less RCT-friendly attitude. Provision of improved training and resources might increase participation of junior providers in RCTs.

Is a randomised controlled trial of a maternity care intervention for pregnant adolescents possible? An Australian feasibility study

Background

The way in which maternity care is provided affects perinatal outcomes for pregnant adolescents; including the likelihood of preterm birth. The study purpose was to assess the feasibility of recruiting pregnant adolescents into a randomised controlled trial, in order to inform the design of an adequately powered trial which could test the effect of caseload midwifery on preterm birth for pregnant adolescents.

Methods

We recruited pregnant adolescents into a feasibility study of a prospective, un-blinded, two-arm, randomised controlled trial of caseload midwifery compared to standard care. We recorded and analysed recruitment data in order to provide estimates to be used in the design of a larger study.

Results

The proportion of women aged 15–17 years who were eligible for the study was 34% (n=10), however the proportion who agreed to be randomised was only 11% (n = 1). Barriers to recruitment were restrictive eligibility criteria, unwillingness of hospital staff to assist with recruitment, and unwillingness of pregnant adolescents to have their choice of maternity carer removed through randomisation.

Conclusions

A randomised controlled trial of caseload midwifery care for pregnant adolescents would not be feasible in this setting without modifications to the research protocol. The recruitment plan should maximise opportunities for participation by increasing the upper age limit and enabling women to be recruited at a later gestation. Strategies to engage the support of hospital-employed staff are essential and would require substantial, and ongoing, work. A Zelen method of post-randomisation consent, monetary incentives and ‘peer recruiters’ could also be considered.

Parents' agendas in paediatric clinical trial recruitment are different from researchers' and often remain unvoiced: a qualitative study

Ensuring parents make an informed decision about their child's participation in a clinical trial is a challenge for practitioners as a parent's comprehension of a trial may differ from that intended by the practitioners responsible for recruitment. We explored what issues parents consider important when making a decision about participation in a paediatric clinical trial and their comprehension of these issues to inform future recruitment practice. This qualitative interview and observational study examined recruitment in four placebo-controlled, double-blind randomised clinical trials of medicines for children. Audio-recorded trial recruitment discussions between practitioners and parents (N = 41) were matched with semi-structured interviews with parents (N = 41). When making a decision about trial entry parents considered clinical benefit, child safety, practicalities of participation, research for the common good, access to medication and randomisation. Within these prioritised issues parents had specific misunderstandings, which had the potential to influence their decisions. While parents had many questions and concerns about trial participation which influenced their decision-making, they rarely voiced these during discussions about the trials with practitioners. Those involved in the recruitment of children to clinical trials need to be aware of parents' priorities and the sorts of misunderstandings that can arise with parents. Providing trial information that is tailored to what parents consider important in making a decision about a clinical trial may improve recruitment practice and ultimately benefit evidence-based paediatric medicine.

Education in health research methodology: use of a wiki for knowledge translation

Introduction

A research-practice gap exists between what is known about conducting methodologically rigorous randomized controlled trials (RCTs) and what is done. Evidence consistently shows that pediatric RCTs are susceptible to high risk of bias; therefore novel methods of influencing the design and conduct of trials are required. The objective of this study was to develop and pilot test a wiki designed to educate pediatric trialists and trainees in the principles involved in minimizing risk of bias in RCTs. The focus was on preliminary usability testing of the wiki.

Methods

The wiki was developed through adaptation of existing knowledge translation strategies and through tailoring the site to the identified needs of the end-users. The wiki was evaluated for usability and user preferences regarding the content and formatting. Semi-structured interviews were conducted with 15 trialists and systematic reviewers, representing varying levels of experience with risk of bias or the conduct of trials. Data were analyzed using content analysis.

Results

Participants found the wiki to be well organized, easy to use, and straightforward to navigate. Suggestions for improvement tended to focus on clarification of the text or on esthetics, rather than on the content or format. Participants liked the additional features of the site that were supplementary to the text, such as the interactive examples, and the components that focused on practical applications, adding relevance to the theory presented. While the site could be used by both trialists and systematic reviewers, the lack of a clearly defined target audience caused some confusion among participants.

Conclusions

Participants were supportive of using a wiki as a novel educational tool. The results of this pilot test will be used to refine the risk of bias wiki, which holds promise as a knowledge translation intervention for education in medical research methodology.

Challenges and successes of recruitment in the "angiotensin-converting enzyme inhibition in infants with single ventricle trial" of the Pediatric Heart Network

OBJECTIVES

Identify trends of enrolment and key challenges when recruiting infants with complex cardiac diseases into a multi-centre, randomised, placebo-controlled drug trial and assess the impact of efforts to share successful strategies on enrolment of subjects.

METHODS

Rates of screening, eligibility, consent, and randomisation were determined for three consecutive periods of time. Sites collectively addressed barriers to recruitment and shared successful strategies resulting in the Inventory of Best Recruiting Practices. Study teams detailed institutional practices of recruitment in post-trial surveys that were compared with strategies of enrolment initially proposed in the Inventory.

RESULTS

The number of screened patients increased by 30% between the Initial Period and the Intermediate Period (p = 0.007), whereas eligibility decreased slightly by 7%. Of those eligible for entry into the study, the rate of consent increased by 42% (p = 0.025) and randomisation increased by 71% (p = 0.10). During the Final Period, after launch of a competing trial, fewer patients were screened (−14%, p = 0.06), consented (−19%, p = 0.12), and randomised (−34%, p = 0.012). Practices of recruitment in the post-trial survey closely mirrored those in the Inventory.

CONCLUSIONS

Early identification and sharing of best strategies of recruitment among all recruiting sites can be effective in increasing recruitment of critically ill infants with congenital cardiac disease and possibly other populations. Strategies of recruitment should focus on those that build relationships with families and create partnerships with the medical providers who care for them. Competing studies pose challenges for enrolment in trials, but fostering trusting relationships with families can result in successful enrolment into multiple studies.

Therapeutic hypothermia after pediatric cardiac arrest trials: the vanguard phase experience and implications for other trials

OBJECTIVE

To determine whether an 18-month vanguard phase, in the Therapeutic Hypothermia after Pediatric Cardiac Arrest trials, confirmed study feasibility and patient safety, a prerequisite to continued funding by the sponsor.

DESIGN

Randomized controlled trial.

SETTING

Pediatric intensive care and pediatric cardiac care units in 15 clinical sites in the United States and Canada.

PATIENTS

Children aged 48 hrs to 18 yrs of age, with return of circulation after cardiac arrest.

INTERVENTIONS

Therapeutic hypothermia vs. therapeutic normothermia.

MEASUREMENTS AND MAIN RESULTS

The first 15 of 20 potential sites to obtain Institutional Review Board and subcontract approvals were selected as vanguard sites. Institutional Review Board approvals were obtained 92 days (median, interquartile range 65-114) and subcontracts signed 34 days (interquartile range 20-48) after distribution. Sites screened subjects at 13 days (interquartile range 9-21) and enrolled the first subjects 64 days (interquartile range 13-154) after study launch. The recruitment milestone was reached 4 months ahead of schedule, with no safety concerns identified. Overall recruitment in this ongoing trial remains on target.

CONCLUSIONS

The Therapeutic Hypothermia after Pediatric Cardiac Arrest vanguard phase proved beneficial for the investigators and funding agency. Because complex multicenter trials are rarely ready to launch when grant funds are received, the vanguard allowed time to refine the protocol and recruitment approaches. Competition for vanguard positions led to expedient Institutional Review Board and subcontract completion. Early success and sustained momentum contributed to recruitment at or above goals. Financial risks to the sponsor were minimized by tying funding for the full trial to achieving prespecified milestones. A vanguard phase may be a desirable strategy for the successful conduct of other complex clinical trials.

Developing a survey of barriers and facilitators to recruitment in randomized controlled trials

BACKGROUND

Recruitment to randomized controlled trials is known to be challenging. It is important to understand and identify predictors of good or poor accrual to a clinical trial so that appropriate strategies can be put in place to overcome these problems and facilitate successful trial completion. We have developed a survey tool to establish the recruitment experience of clinical teams regarding facilitators and barriers to recruitment in a clinical trial and describe herein the method of developing the questionnaire.

METHODS

A literature search was conducted to identify studies that have explored facilitators and barriers to recruitment, and a list of potential factors affecting recruitment to a clinical trial was generated. These factors were categorized in terms relating to the (i) trial, (ii) site, (iii) patient, (iv) clinical team, (v) information and consent and (vi) study team. A list was provided for responders to grade these factors as weak, intermediate or strong facilitators or barriers to recruitment.

RESULTS

A web-based survey questionnaire was developed. This survey was designed to establish the recruitment experience of clinical teams with regard to the perceived facilitators and barriers to recruitment, to identify strategies applied to overcome these problems, and to obtain suggestions for change in the organization of future trials. The survey tool can be used to assess the recruitment experience of clinical teams in a single/multicenter trial in any clinical setting or speciality involving adults or children either in an ongoing trial or at trial completion. The questionnaire is short, easy to administer and to complete, with an estimated completion time of 11 minutes.

CONCLUSIONS

We have presented a robust methodology for developing this survey tool that provides an evidence-based list of potential factors that can affect recruitment to a clinical trial. We recommend that all clinical trialists should consider using this tool with appropriate trial-specific adaptations to monitor and improve recruitment performance in an ongoing trial or conduct the survey at trial completion to gather information on facilitators and barriers to recruitment that can form the basis of interventions and strategies to improve recruitment to future clinical trials.

Do health care institutions value research? A mixed methods study of barriers and facilitators to methodological rigor in pediatric randomized trials

BACKGROUND

Pediatric randomized controlled trials (RCTs) are susceptible to a high risk of bias. We examined the barriers and facilitators that pediatric trialists face in the design and conduct of unbiased trials.

METHODS

We used a mixed methods design, with semi-structured interviews building upon the results of a quantitative survey. We surveyed Canadian (n=253) and international (n=600) pediatric trialists regarding their knowledge and awareness of bias and their perceived barriers and facilitators in conducting clinical trials. We then interviewed 13 participants from different subspecialties and geographic locations to gain a more detailed description of how their experiences and attitudes towards research interacted with trial design and conduct.

RESULTS

The survey response rate was 23.0% (186/807). 68.1% of respondents agreed that bias is a problem in pediatric RCTs and 72.0% felt that there is sufficient evidence to support changing some aspects of how trials are conducted. Knowledge related to bias was variable, with inconsistent awareness of study design features that may introduce bias into a study. Interview participants highlighted a lack of formal training in research methods, a negative research culture, and the pragmatics of trial conduct as barriers. Facilitators included contact with knowledgeable and supportive colleagues and infrastructure for research.

CONCLUSIONS

A lack of awareness of bias and negative attitudes towards research present significant barriers in terms of conducting methodologically rigorous pediatric RCTs. Knowledge translation efforts must focus on these issues to ensure the relevance and validity of trial results.

Factors that influence parental attitudes toward enrollment in type 1 diabetes trials

Aims

To assess parental attitudes towards type 1 diabetes clinical trials (T1DCTs) and factors that impact willingness to enroll their children with and without diabetes.

Methods

A cross-sectional survey of parents of children with type 1 diabetes was administered at an academic clinic and a diabetes educational event.

Results

Survey response rate was 36%. Of 166 participating parents, 76% were aware of T1DCTs. More parents reported willingness to enroll children with diabetes (47%) than unaffected children (36%). Only 18% recalled being asked to enroll their children, and of these, 60% agreed to enroll at least some of those times. Less than 30% were comfortable with placebos. Factors predicting willingness to enroll children with diabetes included healthcare provider trust, comfort with consent by proxy, low fear of child being a “guinea pig,” and comfort with placebo. Factors predicting willingness to enroll unaffected children were provider trust, comfort with consent by proxy, comfort with placebo, and perceived ease of understanding T1DCT information.

Conclusions

Parents report moderate willingness to enroll children in T1DCTs. Willingness is diminished by common trial methodologies. Although most parents recalled receiving trial-related information, significantly fewer recalled being asked to participate. Efforts to optimize effective communication around identified areas of parental concern may increase T1DCT participation.

Parental consent to participation in a randomised trial in children: associated child, family, and physician factors

BACKGROUND

Low participation rates in randomised controlled trials involving children are almost a universal problem, leading to high cost and low statistical power. Trial, parent/family, child, and physician factors have been reported to influence parental willingness to consent for paediatric trials.

PURPOSE

To identify modifiable and unmodifiable factors associated with parental consent.

METHODS

Demographic and clinical characteristics of children and their families and physician characteristics associated with parental consent were evaluated in a recent randomised placebo-controlled trial of prophylactic antibiotics to prevent recurrent urinary tract infection.

RESULTS

Of 1109 eligible children identified (mean age, 2.0 years), 412 parents (37.2%) consented. On a multivariate analysis, the only modifiable factor associated with consent was request for consent by a member of the research study team rather than by a member of the clinical team (risk ratio (RR) = 1.9, 95% confidence interval (CI): 1.2-2.9). The unmodifiable factors significantly associated with consent were age of the child (≥4 years) (RR = 1.2, 95% CI: 1.1-1.4), presence of vesicoureteric reflux (RR = 1.5, 95% CI: 1.3-1.8), inpatient management of the index infection (RR = 0.8, 95% CI: 0.7-0.9), and multiple (≥4) symptoms at presentation (RR = 1.3, 95% CI: 1.1-1.5).

LIMITATIONS

We have reported data from only one of the four participating centres in this trial. Data on non-consenters in other participating centres were not completely collected. Data on characteristics of the recruiting physician were limited. These findings are applicable for those considering a single randomised controlled trial.

CONCLUSIONS

Parent, child, and physician factors are associated with consent for trial participation, with most not being modifiable. Having a member of the research study team approach the parent for consent appears to be the only feasible strategy for increasing recruitment to randomised trials in this setting.

Accrual in supportive care trials in pediatric oncology, a challenge!

PURPOSE

Treatment protocols in pediatric oncology have historically known high accrual rates, up to 94 %. Accrual for supportive care studies on the other hand appears to be a challenge. The aim of this study was to search for reasons explaining this poor accrual and for possible interventions to improve patient enrolment.

METHODS

The failure screen log of our supportive care study (the Aristocaths study) was analyzed, and subsequently, a literature search was performed.

RESULTS

The literature search (1985-2011) revealed three factors that can influence accrual. Firstly, study implementation and patient enrolment can be facilitated by appointing a dedicated clinical investigator in all participating centers and by facilitating clinical research nurses. Furthermore, adequate and tailor-made information is required for families to make a well-informed decision regarding study participation. Lastly, sufficient time should be assured for the process of decision making, especially since the number of eligible studies is increasing rapidly. Concerning our study, all three elements were met, but the most striking finding was the presumed burden of study participation by the majority of parents (82 %) as the main argument against randomization.

CONCLUSIONS

Accrual of pediatric oncology patients in supportive care studies is challenging. Nevertheless, well-designed randomized controlled trials in supportive care will be essential for the improvement of pediatric cancer care. Therefore, we will need to increase awareness through (inter)national supportive care working groups regarding the need for supportive care trials and stimulate accrual when such trials are open.

Improving the recruitment activity of clinicians in randomised controlled trials: a systematic review

Background Poor recruitment to randomised controlled trials (RCTs) is a widespread problem. Provision of interventions aimed at supporting or incentivising clinicians may improve recruitment to RCTs. Objectives To quantify the effects of strategies aimed at improving the recruitment activity of clinicians in RCTs, complemented with a synthesis of qualitative evidence related to clinicians' attitudes towards recruiting to RCTs. Data sources A systematic review of English and non-English articles identified from: The Cochrane Library, Ovid MEDLINE, Ovid EMBASE, Ovid PsycINFO, Ebsco CINAHL, Index to Theses and Open SIGLE from 2001 to March 2011. Additional reports were identified through citation searches of included articles. Study eligibility criteria Quantitative studies were included if they evaluated interventions aimed at improving the recruitment activity of clinicians or compared recruitment by different groups of clinicians. Information about host trial, study design, participants, interventions, outcomes and host RCT was extracted by one researcher and checked by another. Studies that met the inclusion criteria were assessed for quality using a standardised tool, the Effective Public Health Practice Project tool. Qualitative studies were included if they investigated clinicians' attitudes to recruiting patients to RCTs. All results/findings were extracted, and content analysis was carried out. Overarching themes were abstracted, followed by a metasummary analysis. Studies that met the inclusion criteria were assessed for quality using the Critical Appraisal Skills Programme qualitative checklist. Data extraction Data extraction was carried out by one researcher using predefined data fields, including study quality indicators, and verified by another. Results Eight quantitative studies were included describing four interventions and a comparison of recruiting clinicians. One study was rated as strong, one as moderate and the remaining six as weak when assessed for quality using the Effective Public Health Practice Project tool. Effective interventions included the use of qualitative research to identify and overcome barriers to recruitment, reduction of the clinical workload associated with participation in RCTs and the provision of extra training and protected research time. Eleven qualitative studies were identified, and eight themes were abstracted from the data: understanding of research, communication, perceived patient barriers, patient-clinician relationship, effect on patients, effect on clinical practice, individual benefits for clinicians and methods associated with successful recruitment. Metasummary analysis identified the most frequently reported subthemes to be: difficulty communicating trial methods, poor understanding of research and priority given to patient well-being. Overall, the qualitative studies were found to be of good quality when assessed using the Critical Appraisal Skills Programme checklist. Conclusions There were few high-quality trials that tested interventions to improve clinicians' recruitment activity in RCTs. The most promising intervention was the use of qualitative methods to identify and overcome barriers to clinician recruitment activity. More good quality studies of interventions are needed to add to the evidence base. The metasummary of qualitative findings identified understanding and communicating RCT methods as a key target for future interventions to improve recruitment. Reinforcement of the potential benefits, both for clinicians and for their patients, could also be a successful factor in improving recruitment. A bias was found towards investigating barriers to recruitment, so future work should also encompass a focus on successfully recruiting trials.

StaR Child Health: developing evidence-based guidance for the design, conduct, and reporting of pediatric trials

Standards for Research in (StaR) Child Health was founded in 2009 to address the paucity and shortcomings of pediatric clinical trials. This initiative involves international experts who are dedicated to developing practical, evidence-based standards to enhance the reliability and relevance of pediatric clinical research. Through a systematic "knowledge to action" plan, StaR Child Health will make efforts to improve and expand the evidence base for child health across the world.

The ethics of paediatric research

Paediatric research is essential for improving health outcomes of children. Waiting for adult studies before conducting paediatric studies will prolong the denial of effective treatment for children. If we rely on information from adult studies rather than conducting studies with children, we risk causing harm to children. In this paper, we identify and examine ethical issues unique to conducting research with children. These include the function and the value of a child's assent and the criteria that should guide a proxy in making decisions about a child's involvement in research, offering payment to children for research participation and acceptable levels of risk for paediatric research. Justice demands that children not be denied the benefits of research, and it is the role of the paediatric medical community to advocate not only for more research for children but also to ensure that the research conducted is of the highest quality.

Communication about children's clinical trials as observed and experienced: qualitative study of parents and practitioners

BACKGROUND

Recruiting children to clinical trials is perceived to be challenging. To identify ways to optimise recruitment and its conduct, we compared how parents and practitioners described their experiences of recruitment to clinical trials.

METHODS AND FINDINGS

This qualitative study ran alongside four children's clinical trials in 11 UK research sites. It compared analyses of semi-structured interviews with analyses of audio-recordings of practitioner-family dialogue during trial recruitment discussions. Parents from 59 families were interviewed; 41 had participated in audio-recorded recruitment discussions. 31 practitioners were interviewed. Parents said little in the recruitment discussions contributing a median 16% of the total dialogue and asking a median of one question. Despite this, parents reported a positive experience of the trial approach describing a sense of comfort and safety. Even if they declined or if the discussion took place at a difficult time, parents understood the need to approach them and spoke of the value of research. Some parents viewed participation as an 'exciting' opportunity. By contrast, practitioners often worried that approaching families about research burdened families. Some practitioners implied that recruiting to clinical trials was something which they found aversive. Many were also concerned about the amount of information they had to provide and believed this overwhelmed families. Whilst some practitioners thought the trial information leaflets were of little use to families, parents reported that they used and valued the leaflets. However, both parties agreed that the leaflets were too long and wanted them to be more reader-friendly.

CONCLUSIONS

Parents were more positive about being approached to enter their child into a clinical trial than practitioners anticipated. The concerns of some practitioners, that parents would be overburdened, were unfounded. Educating practitioners about how families perceive clinical trials and providing them with 'moral' support in approaching families may benefit paediatric research and, ultimately, patients.

Framework conditions facilitating paediatric clinical research

The use of unlicensed and "off-label" medicines in children is widespread. Between 50-80% of the medicines currently administered to children have neither been tested nor authorized for their use in the paediatric population which represents approximately 25% of the whole European population. On 26 January 2007, entered into force the European Regulation of Paediatric Medicines. It aims at the quality of research into medicines for children but without subjecting the paediatric population to unnecessary clinical trial. This article addresses ethical and legal issues arising from the regulation and makes recommendations for the framework conditions facilitating the development of clinical research with children.

Parental perceptions of research after completion of placebo-controlled trials in pediatric gastroenterology

BACKGROUND AND OBJECTIVES

Investigators may have concerns that parents will not allow their children to participate in placebo-controlled trials (PCTs). The aim of the present study was to identify potential differences between parental perceptions in families who successfully completed (CO) a clinical trial compared with those who were noncompleters (NC).

PATIENTS AND METHODS

Parents of both CO and NC children enrolled in pediatric gastrointestinal studies performed in the previous year were eligible. NC were defined as those who were screen failures or treatment nonresponders or had adverse events. One hundred seven parents were identified and mailed a 26-item questionnaire eliciting perceptions regarding participation in research. Questionnaires were sent 6 months after participation in research ended.

RESULTS

Seventy-eight (69%) parents returned the survey. Characteristics included maternal responders (98%), English as primary language (97%), and education beyond high school (85%). Five parents (4.7%) had children involved in previous research trials. There were no significant differences in responses found between CO (n = 49; 63%) and NC (n = 29; 37%) in regard to importance of research, perceptions of risk to child, benefits to child, and more attention in the study. Statistical significance was approached in regard to the comfort with the research team, with a greater portion of CO stating that the researcher put the parent at ease and the NC feeling less positive about the interaction (P = 0.05).

CONCLUSIONS

A positive perception about participation in research is not stratified by successful completion of a PCT. These results should encourage investigators and institutional review boards that if properly designed and conducted, pediatric PCTs can result in a positive experience for parents.

The placebo response in studies of acute migraine

OBJECTIVES

To characterize the magnitude of the placebo response in trials of migraine therapy in children and adolescents, and to identify its determinants.

STUDY DESIGN

MEDLINE and CENTRAL were searched through November 2006 for randomized controlled trials or controlled clinical trials of pediatric acute migraine pharmacologic treatment that included a placebo comparator group. The main outcomes were headache relief and pain-free response, and effect estimates for risk differences were calculated whenever possible. The influence of placebo response determinants was studied using subgroup analysis. A total of 13 trials (1324 participants in the placebo groups) were included in the analysis.

RESULTS

The pooled placebo responses for pain relief and pain-free at 2 hours were 46% (range, 38% to 53%) and 21% (range, 17% to 26%). Parallel studies conducted in North American centers demonstrated a significantly higher placebo response, as did trials that used 4-point pain scales. Other placebo determinants did not influence the effect estimate, although insufficient data were available to study some of them.

CONCLUSIONS

There is a widely variable placebo response in pediatric migraine trials, supporting the continued use of placebo groups and suggesting the need for more research into the placebo effect in the pediatric population.
