A randomized experimental study to test the effects of discussing uncertainty during cancer genetic counseling: different strategies, different outcomes?

Information needs persist after genetic counseling and testing for BRCA1/2 and Lynch Syndrome

PURPOSE

Research has shown that cancer genetic risk is often not well understood by patients undergoing genetic testing and counseling. We describe the barriers to understanding genetic risk and the needs of high-risk persons and cancer survivors who have undergone genetic testing.

METHODS

Using data from an internet survey of adults living in the USA who responded 'yes' to having ever had a genetic test to determine cancer risk (N = 696), we conducted bivariate analyses and multivariable logistic regression models to evaluate associations between demographic, clinical, and communication-related variables by our key outcome of having vs. not having enough information about genetics and cancer to speak with family. Percentages for yes and no responses to queries about unmet informational needs were calculated. Patient satisfaction with counseling and percentage disclosure of genetic risk status to family were also calculated.

RESULTS

We found that a lack of resources provided by provider to inform family members and a lack of materials provided along with genetic test results were strongly associated with not having enough information about genetics and cancer (OR 4.54 95% CI 2.40-8.59 and OR 2.19 95% CI 1.16-4.14 respectively). Among participants undergoing genetic counseling, almost half reported needing more information on what genetic risk means for them and their family and how genetic testing results might impact future screening.

CONCLUSION

High levels of satisfaction with genetic counseling may not give a full picture of the patient-provider interaction and may miss potential unmet needs of the patient. Accessible resources and ongoing opportunities for updating family history information could reinforce knowledge about genetic risk.

Effects of Prognostic Communication Strategies on Prognostic Perceptions, Treatment Decisions and End-Of-Life Anticipation in Advanced Cancer: An Experimental Study among Analogue Patients

CONTEXT

Evidence-based guidance for oncologists on how to communicate prognosis is scarce.

OBJECTIVES

To investigate the effects of prognostic communication strategies (prognostic disclosure vs. communication of unpredictability vs. non-disclosure; standard vs. standard and best-case vs. standard, best- and worst-case survival scenarios; numerical vs. word-based estimates) on prognostic perceptions, treatment decision-making and end-of-life anticipation in advanced cancer.

METHODS

This experimental study used eight videos of a scripted oncological consultation, varying only in prognostic communication strategies. Cancer-naive individuals, who imagined being the depicted patient, completed surveys before and after watching one video (n = 1036).

RESULTS

Individuals generally perceived dying within 1 year as more likely after prognostic disclosure, compared to communication of unpredictability or non-disclosure (P < 0.001), and after numerical versus word-based estimates (P < 0.001). Individuals felt better informed about prognosis to decide about treatment after prognostic disclosure, compared to communication of unpredictability or non-disclosure (P < 0.001); after communication of unpredictability versus non-disclosure (P < 0.001); and after numerical versus word-based estimates (P = 0.017). Chemotherapy was more often favored after prognostic disclosure versus non-disclosure (P = 0.010), but less often after numerical versus word-based estimates (P < 0.001). Individuals felt more certain about the treatment decision after prognostic disclosure, compared to communication of unpredictability or non-disclosure (P < 0.001). Effects of different survival scenarios were absent. No effects on end-of-life anticipation were observed. Evidence for moderating individual characteristics was limited.

CONCLUSION

If and how oncologists discuss prognosis can influence how individuals perceive prognosis, which treatment they prefer, and how they feel about treatment decisions. Communicating numerical estimates may stimulate prognostic understanding and informed treatment decision-making.

Effects of prognostic communication strategies on emotions, coping, and appreciation of consultations: An experimental study in advanced cancer

OBJECTIVES

We aimed to investigate effects of prognostic communication strategies on emotions, coping, and appreciation of consultations in advanced cancer.

METHODS

For this experimental study, we created 8 videos of a scripted oncological consultation, only varying in prognostic communication strategies. Disease-naive individuals (n = 1036) completed surveys before and after watching 1 video, while imagining being the depicted cancer patient. We investigated effects of the type of disclosure (prognostic disclosure vs. communication of unpredictability vs. non-disclosure) and content of disclosure (standard vs. standard and best-case vs. standard, best- and worst-case survival scenarios; numerical vs. word-based estimates) on emotions, coping, and appreciation of consultations. Moderating effects of individual characteristics were tested.

RESULTS

Participants generally reported more satisfaction (p < .001) after prognostic disclosure versus communication of unpredictability and less uncertainty (p = .042), more satisfaction (p = .005), and more desirability (p = .016) regarding prognostic information after numerical versus word-based estimates. Effects of different survival scenarios were absent. Prognostic communication strategies lacked effects on emotions and coping. Significant moderators included prognostic information preference and uncertainty tolerance.

SIGNIFICANCE OF RESULTS

In an experimental setting, prognostic disclosure does not cause more negative emotions than non-disclosure and numerical estimates are more strongly appreciated than words. Oncologists' worries about harming patients should not preclude disclosing (precise) prognostic information, yet sensitivity to individual preferences and characteristics remains pivotal.

The history of families at-risk for hereditary breast and ovarian cancer: what are the impacts of genetic counseling and testing?

Introduction

Cancer Genetic Counseling (CGC) and genetic testing (GT) assume a paramount role for hereditary cancer predisposition syndrome families. We assessed the effects of CGC and GT on women affected by cancer who are at risk for hereditary breast and ovarian cancer predisposition syndrome (HBOC).

Methods

This study encompasses four time points: before the CGC session, after the CGC session when blood is drawn for GT, after disclosure of GT results, and six months following disclosure of GT results. The impacts of CGC and GT were assessed using psychosocial questionnaires. Additionally, a pedigree, genogram, and ecomap were constructed through a semistructured interview.

Results

A total of sixty women were included in the study. Most participants considered their perception of cancer risk to be equivalent to that of the general population, even among those with pathogenic variants. An increased perception of breast and ovarian cancer risks was associated with a heightened inclination toward religious engagement as a coping mechanism. Patients carrying variants of uncertain significance expressed greater concerns about developing another cancer compared to those who had BRCA1 and BRCA2 wild type or pathogenic variants. Qualitative analysis of the genograms and ecomaps demonstrated that the CGC/GT processes facilitate communication within families. The genogram analyses revealed the impact of CGC and GT processes on families at risk for hereditary cancer. Changes in some family relationships were observed, and an improvement in communication was noted following the GT process.

Discussion

These findings can assist healthcare professionals considering a personalized approaches in clinical practice.

Creating and administering video vignettes for a study examining the communication of diagnostic uncertainty: methodological insights to improve accessibility for researchers and participants

BACKGROUND

Studying clinician-patient communication can be challenging, particularly when research seeks to explore cause-and-effect relationships. Video vignettes - hypothetical yet realistic scenarios - offer advantages to traditional observational approaches by enabling standardisation and manipulation of a clinician-patient encounter for assessment by participants. While published guidelines outline stages to create valid video vignette studies, constructing high quality vignettes which are accessible to a wide range of participants and feasible to produce within time and budget restraints remains challenging. Here, we outline our methods in creating valid video vignettes to study the communication of diagnostic uncertainty. We aim to provide practically useful recommendations for future researchers, and to prompt further reflection on accessibility issues in video vignette methodology.

METHODS

We produced four video vignettes for use in an online study examining the communication of diagnostic uncertainty. We followed established guidelines for vignette production, with specific consideration of how these might be applied pragmatically to save time and resources. Scripts were pilot-tested with 15 laypeople, and videos with 14 laypeople; pilot-testing involved both quantitative and qualitative analysis.

RESULTS AND DISCUSSION

We demonstrate the usefulness of existing guidelines, while also determining that vignette production need not necessarily be expensive or time-consuming to be valid. Our vignettes were filmed using an iPhone camera, and featured a physician rather than a professional actor; nonetheless, pilot-testing found them to be internally and externally valid for experimental use. We thus propose that if care is taken in initial script development and if pragmatic choices are made regarding filming techniques and pilot-testing, researchers can produce valid vignettes within reasonable time and budget restraints. We also suggest that existing research fails to critically examine the potential benefits and harms of online video vignette methodology, and propose that further research should consider how it can be adapted to be inclusive of those from underserved backgrounds.

CONCLUSIONS

Researchers creating video vignette studies can adapt the video vignette development process to suit time and budget constraints, and to make best use of available technology. Online methods may be harnessed to increase participant accessibility, but future research should explore more inclusive vignette design.

How Physicians Discuss Uncertainty With Parents in Intensive Care Units

BACKGROUND AND OBJECTIVES

Physicians and parents of critically ill neonates and children receiving intensive care have to make decisions on the child's behalf. Throughout the child's illness and treatment trajectory, adequately discussing uncertainties with parents is pivotal because this enhances the quality of the decision-making process and may positively affect the child's and parents' well-being. We investigated how physicians discuss uncertainty with parents and how this discussion evolves over time during the trajectory.

METHODS

We asked physicians working in the NICU and PICU of 3 university medical centers to audio record their conversations with parents of critically ill children from the moment doubts arose whether treatment was in the child's best interests. We qualitatively coded and analyzed the anonymized transcripts, thereby using the software tool MAXQDA 2020.

RESULTS

Physicians were found to adapt the way they discussed uncertainty with parents to the specific phase of the child's illness and treatment trajectory. When treatment options were still available, physicians primarily focused on uncertainty related to diagnostic procedures, treatment options, and associated risks and effects. Particularly when the child's death was imminent, physicians had less "scientific" guidance to offer. They eliminated most uncertainty and primarily addressed practical uncertainties regarding the child's dying process to offer parents guidance.

CONCLUSIONS

Our insights may increase physicians' awareness and enhance their skills in discussing uncertainties with parents tailored to the phase of the child's illness and treatment trajectory and to parental needs in each specific phase.

Cancer patients' understandings of genetic variants of uncertain significance in clinical care

Genetic variants of uncertain significance (VUSs) pose a growing challenge for patient communication and care in precision genomic medicine. To better understand patient perspectives of VUSs, we draw on qualitative analysis of semi-structured interviews with 22 cancer patients and individuals with cancer family history who received a VUS result. The majority of patients did not recall receiving VUS results and those who remembered expressed few worries, while respondents who were tested because of a family history of cancer were more concerned about the VUS results. Personal characteristics, medical condition, family history, expectations prior to testing, and motivations for pursuing testing influence the ways patients came to terms with the uncertainty of the VUS result. We conclude by discussing the relevance of the findings to the debate on the responsibility of the patient in checking back for VUS reclassification and to implications for genetic counseling that emphasizes tailoring the pre- and post-test discussion of VUS as appropriate to the patients’ informational as well as emotional needs.

Assessment of psychosocial difficulties by genetic clinicians and distress in women at high risk of breast cancer: a prospective study

We examined how often genetic clinicians correctly identify psychosocial difficulties in women at high breast cancer risk and explored effects of this assessment and the genetic test result on counselees’ distress. A prospective observational study of counselee–clinician dyads was performed in three French, German and Spanish genetic clinics, involving 709 counselees (participation rate, 83.4%) and 31 clinicians (participation rate, 100%). Counselee–clinician agreement in perceived psychosocial difficulties was measured after the pre-test genetic consultation. Multivariate mixed linear models accounting for clinicians were tested. Predicted distress levels were assessed after the pre- (T1) and post-test result disclosure consultations (T2). Depending on the difficulty domain, clinicians adequately assessed the presence or absence of difficulties in 51% (“familial issues”) to 59% (“emotions”) of counselees. When counselees’ and clinicians’ perceptions disagreed, difficulties were generally underestimated by clinicians. Counselees’ distress levels remained stable from T1 to T2, irrespective of clinicians’ appraisal adequacy, and the genetic test result disclosure. Psychological referral need were found in 20–42% of counselees, more frequently observed for difficulties in the “emotions” domain. Our findings suggest that the genetic test result is a suboptimal indicator for psychological referral. Instead, clinicians should focus on emotions expressed by counselees to appraise their needs for psychological support.

Fragmented responsibility: views of Israeli HCPs regarding patient recontact following variant reclassification

While genomic medicine is becoming an important part of patient care with an ever-increasing diagnostic yield, recontacting patients after reclassification of variants of uncertain clinical significance (VUSs) remains a major challenge. Although periodical reinterpretation of VUSs is highly desired, recontacting former patients with new classifications is commonly not fulfilled in practice. We draw on semi-structured interviews with 20 Israeli healthcare professionals and stakeholders involved in communicating the results of genome-wide sequencing to patients. Findings show agreement that an individual health care professional cannot address the task of recontacting patients after re-classification, and that responsibility should be shared among the medical specialties, laboratory scientists, as well as patients. In the absence of established guidelines, many respondents suggested that the patient should be informed about reclassification during a follow-up contact but they disagreed who should be responsible for informing the patient. HCPs agreed that the solution to this challenge involves a centralized automated database that is accessible, continuously updated, and facilitates retrospective as well as prospective flagging of reclassification for patients who can benefit from this information. National and international policies providing concrete guidelines on the optimal way to recontact patients with new valuable genomic information are needed.
