Investigating the Experiences of Childhood Cancer Patients and Parents Participating in Optional Nontherapeutic Clinical Research Studies in the UK

Understanding parents' decision-making on participation in clinical trials in children's heart surgery: a qualitative study

OBJECTIVES

Few children undergoing heart surgery are recruited to clinical trials and little is known about the views and attitudes of parents towards trials. This study explored parents' perspectives on decision-making about their child's participation in a clinical trial during their elective cardiac surgery.

DESIGN

Qualitative interview study.

SETTING

Single-centre substudy of a multicentre, double-blind, randomised controlled trial to investigate the effects of remote ischaemic preconditioning in children undergoing cardiac surgery.

PARTICIPANTS

Parents of children approached to participate in the trial, both consenters and decliners.

METHODS

Semistructured interviews were conducted face-to-face or by telephone following discharge, digitally audio-recorded, transcribed and thematically analysed.

RESULTS

Of 46 patients approached for the trial, 24 consenting and 2 declining parents agreed to participate in an interview (21 mothers, 5 fathers). Parental decision-making about research was influenced by (1) potential risks or additional procedures; (2) personal benefit and altruism for the 'cardiac community'; (3) information, preparation, timing and approach; and (4) trust in the clinical team and collaboration with researchers. All of these were placed within the context of their understanding of the trial and knowledge of research.

CONCLUSIONS

Parents of children undergoing cardiac surgery attach value to clinical research and are supportive of clinical trials when there is no or minimal perceived additional risk. These findings enhance our understanding of the factors that influence parents' decision-making and should be used to inform the design and conduct of future paediatric surgical trials.

Systematic Review of Health Literacy in Childhood Cancer Patients, Survivors, and Their Caregivers

Objective

This systematic review examined the literature regarding health literacy among pediatric cancer patients, survivors, and their caregivers. Specific aims were to identify and summarize measures used, levels of and demographic correlates of health literacy, effects of health literacy interventions, and associations between health literacy and health outcomes.

Methods

The search strategy was executed in the following databases: PubMed, EMBASE, PsycINFO, CINAHL, ERIC, and the Cochrane Library. Of the 842 unique studies retrieved, 9 met the inclusion criteria and were included in the systematic review.

Results

Studies used a variety of validated and study-specific measures with no measure emerging as the standard. Levels of health literacy were typically assessed subjectively and across studies the majority of those sampled self-reported adequate health literacy. Few studies examined demographic correlates of health literacy, precluding the identification of consistent predictors. Health literacy intervention research for this population is in its infancy and only pilot projects were identified; effects could not be evaluated. No studies assessed the impact of health literacy on health outcomes.

Conclusions

Very few studies assessed health literacy in pediatric oncology. As treatment for childhood cancer becomes increasingly complex, and patients and caregivers are expected to have adequate understanding of health information, health literacy is a critical construct that should not be overlooked.

Investigating the roles and training of paediatric research nurses working across Europe: a questionnaire-based survey

BACKGROUND

The key role played by research nurses in coordinating clinical trials in a paediatric setting has developed in line with increasing complexities of trial design. A questionnaire-based survey was conducted to investigate the training of research nurses involved in paediatric trials across Europe, to identify potential training needs and compare roles across specialties and countries.

METHODS

A structured, cross-sectional questionnaire survey was used, with the aim of describing and quantifying research nurse experiences. The questionnaire was designed to cover four main areas of interest: demographics, training, clinical trial experience and research nurse roles/activities.

RESULTS

The questionnaire was completed by 341 respondents across 45 different specialties in 20 European countries. A higher percentage of research nurses within 3 years of taking up post were dissatisfied with the level of training received (16%), as compared with those in post for 3-6 years (8%) and >6 years (6%). There was a trend towards a higher percentage of respondents receiving self-funded training in mainland Europe, with reported values of 15%-20%, as compared with <5% in the UK and Ireland. Only 3% of research nurses prescribed investigational medicinal products in a clinical trial setting, with contrasting roles observed between countries.

CONCLUSIONS

While high levels of training satisfaction were observed, 67% of respondents felt they would benefit from additional training in line with frequently changing practices. Currently, low levels of nurse prescribing are observed in a paediatric clinical trial setting across Europe. Appropriate research nurse training programmes should be promoted through national networks across Europe.
