Approaches for Discussing Clinical Trials with Pediatric Oncology Patients and Their Families

PURPOSE OF REVIEW

This manuscript aims to describe evidence-based best practices to guide clinicians in communicating with pediatric patients and their families about clinical trial enrollment.

RECENT FINDINGS

The standard paradigm for discussing clinical trial enrollment with pediatric oncology patients and their families inconsistently enables or facilitates true informed consent. Evidence exists to suggest that adopting a shared decision-making approach may improve patient and family understanding. When navigating communication about clinical trials, clinicians should integrate the following evidence-based communication approaches: (1) extend dialogue about clinical trial enrollment across multiple conversations, allowing families space and time to process information independently; (2) use core communication skills such as avoiding jargon, checking for understanding, and responding to emotion. Clinicians should consider factors at the individual, team, organizational, community, and policy levels that may impact clinical trial communication with pediatric cancer patients and their families. This article reviews learnable skills that clinicians can master to optimize communication about clinical trial enrollment with pediatric cancer patients and their families.

Assessment of Factors Associated With Parental Perceptions of Voluntary Decisions About Child Participation in Leukemia Clinical Trials

IMPORTANCE

Obtaining voluntary informed consent prior to enrollment in clinical trials is a fundamental ethical requirement.

OBJECTIVE

To assess whether health literacy, contextual factors, or sociodemographic characteristics are associated with perception of voluntariness among parents who had consented for their child's participation in a leukemia therapeutic clinical trial.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study prospectively enrolled 97 parents of children diagnosed as having leukemia at Rady Children's Hospital San Diego, a large tertiary academic center in California, from 2014 to 2017. Health literacy, contextual factors (acculturation, decisional regret, and satisfaction with informed consent), sociodemographic characteristics, and perception of voluntariness after consenting for a therapeutic clinical trial were measured. Univariable and multivariable regression were used to determine significant associations. The analyses for the present study were conducted from May 2019 to May 2020.

EXPOSURES

Informed consent for a therapeutic leukemia clinical trial.

MAIN OUTCOMES AND MEASURES

The primary outcome of interest was perception of voluntariness and its associations with health literacy and other contextual factors (acculturation, decisional regret, and satisfaction with informed consent) and sociodemographic characteristics, including age, race/ethnicity, parental language, educational level, insurance type, marital status, and socioeconomic status.

RESULTS

Of 97 parents included, the majority were women (65 [67%]), married (71 [73%]), and of self-reported Hispanic ethnicity (50 [52%]). Lower perception of voluntariness was significantly associated with lower health literacy (r = 0.30; 95% CI, 0.11-0.47; P = .004), Spanish language (x̅ = -4.50, P = .05), lower acculturation if of Hispanic ethnicity (r = 0.30; 95% CI, 0.02-0.54; P = .05), greater decisional regret (r = -0.54; 95% CI, -0.67 to -0.38; P < .001), and lower satisfaction with informed consent (r = 0.39; 95% CI, 0.21-0.54; P < .001) in univariable analysis. Lower health literacy remained significantly associated with lower perception of voluntariness in multivariable analysis after adjustment for contextual factors and sociodemographic characteristics (β = 4.06; 95% CI, 1.60-6.53; P = .001). Lower health literacy was significantly associated with Hispanic ethnicity (mean, 4.16; 95% CI, 3.75-4.57; P < .001), Spanish language spoken at home (mean, 3.17; 95% CI, 1.94-4.40; P < .001), high school or less educational level (mean, 3.41; 95% CI, 2.83-3.99; P < .001), public insurance (mean, 4.00; 95% CI, 3.55-4.45; P < .001), and unmarried status (mean, 3.71; 95% CI, 2.91-4.51; P = .03).

CONCLUSIONS AND RELEVANCE

Among parents of children with newly diagnosed leukemia who had consented for their child's participation in a therapeutic clinical trial, lower perception of voluntariness was significantly associated with lower health literacy. These results suggest that parents with low health literacy may perceive external influences in their decision for their child's participation in clinical trials. This finding highlights the potential role of recruitment interventions tailored to the participant's health literacy level to improve voluntary informed consent in underserved populations.

A Conceptual Model of Financial Toxicity in Pediatric Oncology

The purpose of this article is to explicate a conceptual framework for financial toxicity in pediatric oncology to guide nursing practice and research. The framework is based on one for financial outcomes of severe illness attributed to Scott Ramsey and adapted by the National Cancer Institute to describe relationships between preexisting factors, a cancer diagnosis, financial distress, and health outcomes for adult cancer patients and survivors. The adaption for pediatric oncology was informed by the results of a systematic scoping review to identify advances and gaps in the recent literature about the personal costs of illness to parents in the pediatric oncology context. The conceptual model for pediatric oncology indicates that existing and dynamic parent and family factors, other risk and protective factors, the child's diagnosis and treatment, and treatment-related financial costs can affect parent financial coping behaviors and parent health and family financial outcomes, all of which may affect child outcomes. Additionally, nursing's historic emphasis on holistic care, quality of life, and health determinants justify attention to financial toxicity as a nursing role. Therefore, pediatric oncology nurses must be sensitive to financial toxicity and related risk factors, become comfortable communicating about treatment-related financial costs and financial distress with parents and other health professionals, and collaborate in efforts that draw on the expertise of multiple stakeholders to identify potential or actual financial toxicity in parents and mitigate its impact on childhood cancer health outcomes through direct care, referral, research, quality improvement, and health advocacy.

Education Milestones for Newly Diagnosed Pediatric, Adolescent, and Young Adult Cancer Patients: A Quality Improvement Initiative

The diagnosis of cancer in a child, adolescent, or young adult is an emotionally overwhelming time. To improve the quality of education and support provided to patients and caregivers with a new cancer diagnosis, we executed a quality improvement initiative to (a) define key education milestones for the delivery of essential education during the first 2 months following diagnosis and (b) to define role accountability within the multidisciplinary team for delivery of content and execution of tasks. To develop education milestones, we (a) identified educational content from review of the literature, (b) determined the sequence of content delivery through qualitative interviews with patients and caregivers, and (c) developed education milestones by evaluation of existing workflows. To develop task lists, we (a) determined which multidisciplinary team member was best suited to deliver specific content and (b) defined discrete tasks required to execute education milestones. Key content topics and preferred sequence are as follows: Emotional Adjustment to Diagnosis, When and How to Call the Doctor, Medication Management, Practical Needs, Line Care, and Access to Nontherapeutic Clinical Trials. Eight education milestones were defined across the initial 2 months following cancer diagnosis. The education milestones are paired with task lists. The education milestones and task lists guide the execution of complex education across a multidisciplinary service line in an emotionally challenging time. Early information focuses on essential content, role responsibility is clearly defined, and psychosocial support services are purposefully and iteratively integrated into care during the initial weeks following a cancer diagnosis.

The Process and Impact of Stakeholder Engagement in Developing a Pediatric Intensive Care Unit Communication and Decision-Making Intervention

Stakeholder-developed interventions are needed to support pediatric intensive care unit (PICU) communication and decision-making. Few publications delineate methods and outcomes of stakeholder engagement in research. We describe the process and impact of stakeholder engagement on developing a PICU communication and decision-making support intervention. We also describe the resultant intervention. Stakeholders included parents of PICU patients, healthcare team members (HTMs), and research experts. Through a year-long iterative process, we involved 96 stakeholders in 25 meetings and 26 focus groups or interviews. Stakeholders adapted an adult navigator model by identifying core intervention elements and then determining how to operationalize those core elements in pediatrics. The stakeholder input led to PICU-specific refinements, such as supporting transitions after PICU discharge and including ancillary tools. The resultant intervention includes navigator involvement with parents and HTMs and navigator-guided use of ancillary tools. Subsequent research will test the feasibility and efficacy of our intervention.

The Adolescent and Young Adult with Cancer: A Developmental Life Course Perspective

OBJECTIVES

Using a Life Course Health Development framework, this article summarizes what is known about the impact of cancer and its treatment on the biopsychosocial world of the adolescent and young adult.

DATA SOURCES

Published peer reviewed literature, web-based resources, and cancer-related professional organizations' resources.

CONCLUSION

Adolescents and young adults with cancer, between 15 and 29 years of age, have emerged as a distinct group requiring specialized care. The demands of cancer and its treatment are often directly counter to the developmental needs of this age group and often alter those life course experiences that contribute to resilience, thriving, and flourishing.

IMPLICATIONS FOR NURSING PRACTICE

Providing high-quality care to this age group requires a depth of understanding of the complexity of factors that merge to influence the developmental life course.

Patient involvement in informed consent for pediatric phase I cancer research

OBJECTIVE

To examine children's and adolescents' involvement in the informed consent conference for phase I cancer trials and test associations with patient age, ease of understanding, and pressure to participate.

PROCEDURE

Participants included 61 patients aged 7 through 21 years who were offered participation in a phase I trial. Consent conferences were audiotaped, transcribed, and coded for communication between patients and physicians and between patients and parents.

RESULTS

On the basis of word counts, the mean proportion of the consent conference in which the physician was talking to the patient was 36%; the vast majority (73%) of this communication consisted of giving information. Physician-patient communication increased with age, but overall levels of patient-to-physician communication were low (3%). After controlling for patient age, greater physician-to-patient communication was associated with greater ease of understanding.

CONCLUSIONS

The focus on providing information in the context of informed consent may come at the expense of other communication exchanges that are important to patients, especially in the context of end-of-life decisions. Children and adolescents may benefit from the assent process when physicians direct more of their communication to them. Future research should identify the reasons for low patient communication during the consent conference and strategies to enhance their participation in decision making about phase I trial enrollment.

Factors related to voluntary parental decision-making in pediatric oncology

OBJECTIVE

The aim of the current study was to examine demographic and contextual correlates of voluntariness in parents making research or treatment decisions for their children with cancer.

METHODS

Participants included 184 parents of children with cancer who made a decision about enrolling the child in a research or treatment protocol within the previous 10 days. Parents completed questionnaires that assessed voluntariness, external influence by others, concern that the child's care would be negatively affected if the parent did not agree, time pressure, information adequacy, and demographics.

RESULTS

Lower perceived voluntariness was associated with lower education, male gender, minority status, and not having previous experience with a similar decision. Parents who reported lower voluntariness also perceived more external influence and time pressure, had more concern about the child's care being negatively affected if they declined, and perceived that they had either too much or not enough information about the decision. In a multivariate regression, education, minority status, gender, external influence, and too little information remained significantly associated with voluntariness.

CONCLUSIONS

Several groups of parents appear to be at risk for decreased voluntariness when making research or treatment decisions for their seriously ill children, including fathers, nonwhite parents, and those with less education. Parental voluntariness may be enhanced by helping parents to mitigate the effects of unhelpful or unwanted influences by others and ensuring that their information needs are met.

Parental views on tissue banking in pediatric oncology patients

PURPOSE

Research using banked tissue is key to advancing risk-stratification and treatment of children with cancer. Knowledge of parental attitudes to ethical issues arising in tissue banking is very limited but essential in obtaining respectful consent.

METHODS

One hundred parents of consecutively diagnosed children with cancer were offered a validated 34-item questionnaire.

RESULTS

Respondents (n = 54) included 10 of 16 parents of deceased children. The majority (89%; n = 48) would agree to have tissue sent anywhere in the world but prefer pediatric aims (69%). Most (98%; n = 53) would permit genetic research, if it might improve the child's health, and 76% (n = 41) would permit it, even if no impact was anticipated. A minority (41%) would not allow painful, strictly research procedures, while 15% would regardless of the child's dissent. Just over half (54%; n = 29) wish to renew consent if stored tissue is used for another purpose. Most (98%) believe their child should confirm consent by the age of majority, but only 71% believe the mature child should be able to withdraw consent. A minority (n = 40; 74%) claim few or no rights to research profits; 83% believe these should be used to fund childhood cancer research.

CONCLUSIONS

Parents are very supportive of tissue research, including genetic research. A majority of parents would prefer restricting research to pediatric conditions, and to be informed of results, even if of uncertain significance. These findings may assist Institutional Review Boards in assessing parentally perceived risks of research, and researchers in providing consent elements that support parents and adolescents in making fully informed choices.

Outcomes of informed consent among parents of children in cancer clinical trials

BACKGROUND

Clinical trials are central to pediatric oncology, yet the process and outcomes of informed consent are poorly understood. We evaluated correlates of understanding among parents of pediatric trial participants, and explored differences in the process and outcome of informed consent between parents and a comparison group of adult participants.

PROCEDURE

We administered the Quality of Informed Consent (QuIC) to parents of children who were newly enrolled onto a cancer trial. We identified independent correlates of knowledge among parents, and compared parents' knowledge to that of a contemporaneous group of adult participants, using multiple linear regression models.

RESULTS

Parents (n = 47) were less likely than adult participants (n = 204) to report having enough time to learn about the trial (64% vs. 87%, P = 0.001) or sufficient opportunity for questions (79% vs. 93%, P = 0.01), and reported lower overall satisfaction with the consent process (71% vs. 90%, P = 0.002). The mean parental knowledge score was 73.6 (95% confidence interval [CI] 69.5-77.8, theoretical maximum 100). Knowledge did not differ between parents and adult trial participants. In multivariate analysis, two predictors were significantly associated with higher parent knowledge scores: consent sought by the study's principal investigator (increment 13.6, CI 2.7-24.6) and physician-reported poor prognosis (increment 13.8, 95% CI 5.4-22.1).

CONCLUSIONS

Although we observed no differences in knowledge between parents of pediatric cancer trial participants and their adult counterparts, parents report more problems with the informed consent process for their trials. The increased prevalence of problems is likely due to clinical and contextual differences between pediatric and adult trials.

Parent participation and physician-parent communication during informed consent in child leukemia

OBJECTIVE

In this study we evaluated the effectiveness of a physician-directed intervention at enhancing positive physician behaviors and communication strategies during informed consent conferences (ICCs) for pediatric acute leukemia clinical trials.

PATIENTS AND METHODS

Physicians at 2 large pediatric hospitals were recruited to participate in a physician-directed intervention (PDI), which included 1 full-day seminar and successive half-day booster sessions. ICCs were then observed, audiotaped, coded, and analyzed to evaluate the effectiveness of the intervention. Data also were collected at 2 control sites. Between 2003 and 2007, 59 ICCs were observed and analyzed.

RESULTS

Significant group differences were found in physician rapport-building behaviors. Physicians in the PDI + booster session group engaged in greater rapport-building than did physicians in the PDI group who did not attend booster sessions and physicians in the control group. No group differences were detected for physician partnership-building. In addition, parents in the PDI + booster session group engaged in more general communication and study-related communication, and mothers in the PDI groups asked significantly more questions per minute than did mothers in the control group.

CONCLUSIONS

These results provide support for the effectiveness of the PDI at enhancing positive physician behaviors. Booster-session attendance is a critical component of physician-directed interventions to improve parental participation and physician-parent communication during ICCs.

A feasibility trial of a video intervention to improve informed consent for parents of children with leukemia

BACKGROUND

Research on parental understanding of informed consent for pediatric randomized clinical trials (RCTs) has highlighted weaknesses in understanding of key aspects of informed consent. The goals of the current study were to assess the feasibility of and parental satisfaction with a video intervention to improve informed consent for pediatric leukemia RCTs and to compare parental question asking during informed consent conferences (ICCs) for parents in the current study with historical control data.

PROCEDURE

A 20-min video was produced. Utilizing the principles of anticipatory guidance, it included information delivered by nurses and physicians about leukemia and key aspects of informed consent. Parents were encouraged to be active participants in ICCs. Participants included 12 parents of children newly diagnosed with pediatric leukemia. The video was viewed by local pediatric oncologists prior to utilization with families.

RESULTS

Ninety-two percent of parents reported that the video made it easier to understand information that their child's physician later provided; 83% of parents reported that it helped them to think of questions to ask the physician; and 67% of parents indicated that the video made them feel more comfortable with asking questions of the physician. Results of a t-test comparing question asking during ICCs revealed that parents who participated in the intervention asked a higher rate of questions than parents from a historical control sample (t = 1.95, P = 0.05).

DISCUSSION

Our study supports the feasibility and potential efficacy of a brief video intervention employing anticipatory guidance to prepare parents for future discussions about RCTs.

A physician-directed intervention: teaching and measuring better informed consent

PURPOSE

To improve physician communication with parents using a physician-directed intervention (PDI), emphasizing a sequenced approach to the informed consent conference (ICC) for childhood leukemia clinical trials in which physicians discuss diagnosis, prognosis, and treatment prior to the offer of a clinical trial.

METHOD

Physicians and fellows at the Children's Hospital of Philadelphia and Children's National Medical Center were recruited to participate in Informed Consent Seminars and subsequent half-day booster sessions. Training was followed by a multisite study of informed consent communication. Real-life ICCs were observed and audiotaped, and parents were interviewed after the ICC to ascertain their understanding. Data from the ICC and interview were then coded and analyzed. Trained physician performances were compared with untrained physicians (controls) at two other research sites. Data were collected from 2003 to 2007 at PDI sites and control sites for comparison.

RESULTS

A total of 102 cases were included for initial analyses, with 60 cases from the PDI sites and 42 control cases. Fifty-nine cases were included in the final analysis. Findings revealed that trained physicians followed the sequenced approach more often when compared with controls. Similarly, physicians at the PDI sites tended to elicit parental questions and understanding in an open-ended way and clarify parents' questions more frequently than physicians at the control sites.

CONCLUSIONS

Academic physicians who are involved in the current transformation of clinical research should be trained to conduct effective ICCs. The "see one, do one, teach one" approach is no longer adequate for informed consent.
