Large language models as decision aids in neuro-oncology: a review of shared decision-making applications

Shared decision-making (SDM) is crucial in neuro-oncology, fostering collaborations between patients and healthcare professionals to navigate treatment options. However, the complexity of neuro-oncological conditions and the cognitive and emotional burdens on patients present significant barriers to achieving effective SDM. This discussion explores the potential of large language models (LLMs) such as OpenAI's ChatGPT and Google's Bard to overcome these barriers, offering a means to enhance patient understanding and engagement in their care. LLMs, by providing accessible, personalized information, could support but not supplant the critical insights of healthcare professionals. The hypothesis suggests that patients, better informed through LLMs, may participate more actively in their treatment choices. Integrating LLMs into neuro-oncology requires navigating ethical considerations, including safeguarding patient data and ensuring informed consent, alongside the judicious use of AI technologies. Future efforts should focus on establishing ethical guidelines, adapting healthcare workflows, promoting patient-oriented research, and developing training programs for clinicians on the use of LLMs. Continuous evaluation of LLM applications will be vital to maintain their effectiveness and alignment with patient needs. Ultimately, this exploration contends that the thoughtful integration of LLMs into SDM processes could significantly enhance patient involvement and strengthen the patient-physician relationship in neuro-oncology care.

A surgical decision aid for occipital neuralgia with literature review and single center case series

BACKGROUND

Occipital neuralgia (ON) is a debilitating headache disorder. Due to the rarity of this disorder and lack of high-level evidence, a clear framework for choosing the optimal surgical approach for medically refractory ON incorporating shared decision making with patients does not exist.

METHODS

A literature review of studies reporting pain outcomes of patients who underwent surgical treatment for ON was performed, as well as a retrospective chart review of patients who underwent surgery for ON within our institution.

RESULTS

Thirty-two articles met the inclusion criteria. A majority of the articles were retrospective case series (22/32). The mean number of patients across the studies was 34 (standard deviation (SD) 39). Among the 13 studies that reported change in pain score on 10-point scales, a study of 20 patients who had undergone C2 and/or C3 ganglionectomies reported the greatest reduction in pain intensity after surgery. The studies evaluating percutaneous ablative methods including radiofrequency ablation and cryoablation showed the smallest reduction in pain scores overall. At our institution from 2014 to 2023, 11 patients received surgical treatment for ON with a mean follow-up of 187 days (SD 426).

CONCLUSION

Based on these results, the first decision aid for selecting a surgical approach to medically refractory ON is presented. The algorithm prioritizes nerve sparing followed by non-nerve sparing techniques with the incorporation of patient preference. Shared decision making is critical in the treatment of ON given the lack of clear scientific evidence regarding the superiority of a particular surgical method.

Barriers and facilitators of meaningful patient participation at the collective level in healthcare organizations: A systematic review

INTRODUCTION

Collective patient participation, such as patient participation in policy making, has become increasingly important to achieve high-quality care. However, there is little knowledge on how to let patients participate in a meaningful manner at this level. The aim of this systematic literature review was to provide an overview of barriers, facilitators, and associated impact of collective patient participation.

METHODS

PubMed and EMBASE were searched until May 2023 for studies that evaluated collective patient participation. Study characteristics, methods for patient participation, barriers and facilitators, and impact (if measured) of patient participation were extracted from the articles.

RESULTS

We included 59 articles. Identified barriers and facilitators of collective patient participation were grouped into five categories: (1) preconditions for patient participation, (2) strategy for patient participation, (3) preparation of patients and staff for patient participation, (4) support for patients and staff during patient participation, and (5) evaluation of patient participation. Impact of patient participation was reported in 34 included studies at three levels: quality of care and research, the team and organization, and the participants themselves. Only three studies reported quantitative outcomes.

CONCLUSION

Interestingly, similar challenges were experienced during a period of twenty years, indicating that little progress has been made in structuring patient participation. Our overview of barriers and facilitators will therefore help to improve and structure collective patient participation.

Futility and Shared Decision-Making

Medical futility is an ancient and yet consistent challenge in clinical medicine. The means of balancing conflicting priorities and stakeholders' preferences has changed as much as the science that powers the understanding and treatment of disease. The introduction of patient self-determination and choice in medical decision-making shifted the locus of power in the physician-patient relationship but did not obviate the physician's responsibilities to provide benefit and prevent harm. As we have refined the process in time, new paradigms, specialists, and tools have been developed to help navigate the ever-changing landscape.

The patients' experience of neuroimaging of primary brain tumors: a cross-sectional survey study

PURPOSE

To gain insight into how patients with primary brain tumors experience MRI, follow-up protocols, and gadolinium-based contrast agent (GBCA) use.

METHODS

Primary brain tumor patients answered a survey after their MRI exam. Questions were analyzed to determine trends in patients' experience regarding the scan itself, follow-up frequency, and the use of GBCAs. Subgroup analysis was performed on sex, lesion grade, age, and the number of scans. Subgroup comparison was made using the Pearson chi-square test and the Mann-Whitney U-test for categorical and ordinal questions, respectively.

RESULTS

Of the 100 patients, 93 had a histopathologically confirmed diagnosis, and seven were considered to have a slow-growing low-grade tumor after multidisciplinary assessment and follow-up. 61/100 patients were male, with a mean age ± standard deviation of 44 ± 14 years and 46 ± 13 years for the females. Fifty-nine patients had low-grade tumors. Patients consistently underestimated the number of their previous scans. 92% of primary brain tumor patients did not experience the MRI as bothering and 78% would not change the number of follow-up MRIs. 63% of the patients would prefer GBCA-free MRI scans if diagnostically equally accurate. Women found the MRI and receiving intravenous cannulas significantly more uncomfortable than men (p = 0.003). Age, diagnosis, and the number of previous scans had no relevant impact on the patient experience.

CONCLUSION

Patients with primary brain tumors experienced current neuro-oncological MRI practice as positive. Especially women would, however, prefer GBCA-free imaging if diagnostically equally accurate. Patient knowledge of GBCAs was limited, indicating improvable patient information.

A Shared Decision-Making Process Utilizing a Decision Coach in Pediatric Epilepsy Surgery

BACKGROUND & RATIONALE

The process to evaluate candidacy for epilepsy surgery is lengthy and stressful for caregivers, therefore the decision can be challenging. There is not a lot of information in regard to how families of a child living with epilepsy navigate the stressful decision during surgical candidacy evaluation. With difficult decisions comes the possibility of increased decisional conflict in both the child and the family.

METHODS

A project designed to provide greater knowledge to the family was conducted utilizing the shared decision-making (SDM) process to assist families in the decision-making during surgical candidacy evaluation; this was done using a decision coach, who is an unbiased health care professional, providing families with evidence-based information and support tools while supporting them in making decisions based on their values.

RESULTS

Results reveal that 90% (45 of 50) of families offered a consult with the decision coach agreed to participate. For these families, 78% (35 of 45) felt they were ready to move forward with surgery after the consult and 22% (10 of 45) felt they needed more information and testing. There was a significant improvement in the level of decisional conflict, uncertainty, and perception of preparation for decision making for the caregivers between the first and second consult, although 60% of families did not complete the postconflict survey.

CONCLUSIONS

The SDM process assists families in their need for more knowledge regarding risks, benefits, and options for treatment before making a surgical choice. SDM utilizing an impartial decision coach outside the direct circle of care and individualized epilepsy surgery education aids improves parental decision conflict and satisfaction.

Surgery versus radiosurgery for vestibular schwannoma: Shared decision making in a multidisciplinary clinic

Background

Our neurosurgical unit adopted a model of shared decision-making (SDM) based on multidisciplinary clinics for vestibular schwannoma (VS). A unique feature of this clinic is the interdisciplinary counseling process with a surgeon presenting the option of surgery, an oncologist radiosurgery or radiotherapy, and a specialist nurse advocating for the patient.

Methods

This is a retrospective cohort study. All new patients seen in the combined VS clinic and referred from the skull base multidisciplinary team (MDT) from beginning of June 2013 to end of January 2019 were included. Descriptive statistics and frequency analysis were carried out for the full cohort.

Results

Three hundred and fifty-four patients presenting with new or previously untreated VS were included in the analysis. In our cohort, roughly one-third of patients fall into each of the treatment strategies with slightly smaller numbers of patients undergoing surgery than watch, wait and rescan (WWR) ,and SRS (26.6% vs. 32.8% and 37.9%, respectively).

Conclusion

In our experience, the combined surgery/oncology/specialist nurse clinic streamlines the patient experience for those with a VS suitable for either microsurgical or SRS/radiotherapy treatment. Decision-making in this population of patients is complex and when presented with all treatment options patients do not necessarily choose the least invasive option as a treatment. The unique feature of our clinic is the multidisciplinary counseling process with a specialist nurse advocating and guiding the patient. Treatment options are likely to become more rather than less complex in future years making combined clinics more valuable than ever in the SDM process.

Disability or Death: A Focused Review of Informed Consent in Pediatric Neurosurgery

The management of pediatric neurosurgical disease often requires families to choose between long-term disability and premature death. This decision-making is codified by informed consent. In practice, decision-making is heavily weighted toward intervening to prevent death, often with less consideration of the realities of long-term disability. We analyze long-term disability in pediatric neurosurgical disease from the perspectives of patients, families, and society. We then present a pragmatic framework and conversational approach for addressing informed consent discussions when the outcome is expected to be death or disability. We performed a focused review of literature regarding informed consent in pediatric neurosurgery by searching PubMed and Google Scholar with search terms including "pediatric neurosurgery," "informed consent," and "disability." The literature was focused on patients with diagnoses including spina bifida, neuro-oncology, trauma, and hydrocephalus. Patient perspective elements were physical/mental disability, lack of autonomy, and role in community/society. The family perspective involves caregiver burden, emotional toll, and financial impact. Societal considerations include the availability of public resources for disabled children, large-scale financial cost, and impacts on global health. Practical conversational steps with patients/caregivers include opening the discussion, information provision and acknowledgement of uncertainty, assessment of understanding and clarifying questions, decision-making, and decision maintenance, all while remaining sensitive to the emotional burden commensurate with these decisions. The "death or disability" paradigm represents a common challenge to informed consent in pediatric neurosurgery. Patient, family, and societal factors that inform surrogate decisions vary and sometimes conflict. Pediatric neurosurgeons must use a comprehensive approach to address the informational and relational needs of caregivers during the informed consent process.

Utility of 3-dimensionally printed models for parent education in pediatric plagiocephaly

Objectives

Demonstrate the benefits of using 3D printed skull models when counseling families regarding disorders of the cranial vault (namely plagiocephaly and craniosynostosis), as traditional imaging review and discussion is often insufficient.

Methods

3D printed skull models of a patient with plagiocephaly were used during clinic appointments to aid in the counseling of parents. Surveys were distributed following the appointment to evaluate the utility of these models during the discussion.

Results

Fifty surveys were distributed (with a 98% response rate). 3D models were both empirically and anecdotally helpful for parents in understanding their child's diagnosis.

Conclusion

Advances in 3D printing technology and software have made producing models more accessible. Incorporating physical, disorder-specific models into our discussions has led to improvements in our ability to communicate with our patients and their families.

Innovation

Disorders of the cranial can be challenging to describe to the parents and guardians of affected children; using 3D printed models is a useful adjunct in patient-centered discussions. The subject response to the use of these emerging technologies in this setting suggests a major role for 3D models in patient education and counseling for cranial vault disorders.

Disparities in place of death for patients with primary brain tumors and brain metastases in the USA

PURPOSE

Patients with primary or metastatic brain tumors often require intensive end-of-life care, for which place of death may serve as a quality metric. Death at home or hospice is considered a more "ideal" location. Comprehensive information on place of death of people with brain tumors is lacking.

METHODS

Using CDC Wonder Database data, those who died in the USA from a solid cancer from 2003 to 2016 were included and place of death for those with primary brain, brain metastases, and solid non-brain tumors were compared. Multivariate logistic regression tested for disparities in place of death.

RESULTS

By 2016, 51.1% of patients with primary brain tumors and 45.2% with brain metastases died at home. 15.9% of patients with primary brain tumors and 23.6% with brain metastases died in the hospital. Black patients were least likely to die at home or hospice. For patients with primary brain tumors, being married (OR = 2.25 (95%CI 2.16-2.34), p < 0.01) and having an advanced degree (OR = 1.204 (95%CI 1.15-1.26), p < 0.01) increased odds of home/hospice death; older age (OR = 0.50 (95%CI 0.46-0.54), p < 0.01) decreased odds for home/hospice death. For patients with brain metastases, being married (OR = 2.19 (95%CI 2.11-2.26), p < 0.01) increased odds of home/hospice death and male sex (OR = 0.87 (095%CI .85-0.89), p < 0.01) and older age (OR = 0.59 (95%CI 0.47-0.75), p < 0.01) decreased odds of home/hospice death.

CONCLUSION

Disparities exist in place of death in the brain tumor population. Focused interventions are indicated to increase the utilization of hospice in those with metastatic cancer, under-represented minority groups, and the elderly population.

Development of a Patient Decision Aid to Support Shared Decision Making for Patients with Recurrent High-Grade Glioma

When high-grade gliomas recur, patients, their families, and clinicians face difficult medical decisions. There is no curable treatment, and the treatment options all come with a risk of complications and adverse effects. The patients are often cognitively affected, and they need tailored decision support. The objective of this study was to develop a patient decision aid (PtDA) targeted at patients with recurrent high-grade gliomas. Based on existing knowledge and the International Patient Decision Aids Standards, the PtDA was developed through an iterative process. The PtDA was alpha-tested by potential users to assess its acceptability and usability. The development team comprised three clinicians, two patients, two family members, and a researcher. The fifth version of the PtDA was submitted to the alpha test. Eleven patients, nine family members, and eleven clinicians assessed the PtDA and found it acceptable. Three changes were made during the alpha test. Most participants perceived the PtDA to prepare patients for decision making and improve consultations. The involvement of potential users was emphasized during the development and alpha test process. The PtDA was assessed as useful and acceptable by patients, family members, and clinicians in the decision-making situation of recurrent high-grade glioma.

Decisional needs of patients with recurrent high-grade glioma and their families

Background

High-grade gliomas are aggressive and life-threatening brain tumors. At the time of recurrence, the patients and their families need to decide on future treatment. None of the treatment options are curative, and tradeoffs between benefits and harms must be made. This study aimed to explore the patients’ and family members’ decisional needs when making the decision.

Methods

We performed semi-structured individual interviews with patients and family members to explore their experiences during the decision making. A phenomenological hermeneutical analysis was conducted.

Results

A total of 15 patients and 14 family members aged 22-79 years participated in the study. Most of the family members were partners to the patient. The findings were centered around three interrelated and concurrently occurring themes: (I) A patient- and family-centered decision making, including the subtheme of being a supportive family member; (II) Balanced information and a trustful professional encounter; and (III) The value of hope. We found that both the patients and family members preferred to be involved in the decision making and that a trustful relationship with the surgeon, balanced and tailored information, and sufficient time to make the decision were essential. The experience of hope had a significant influence on patients’ decisions.

Conclusion

This study found that patient and family involvement, balanced information, and hope were the primary decisional needs of patients and family members at the time of recurrent high-grade glioma. Patients and family members can have different decisional needs, making individual needs assessment essential to decisional support.

Prediction of glioma-subtypes: comparison of performance on a DL classifier using bounding box areas versus annotated tumors

Background

For brain tumors, identifying the molecular subtypes from magnetic resonance imaging (MRI) is desirable, but remains a challenging task. Recent machine learning and deep learning (DL) approaches may help the classification/prediction of tumor subtypes through MRIs. However, most of these methods require annotated data with ground truth (GT) tumor areas manually drawn by medical experts. The manual annotation is a time consuming process with high demand on medical personnel. As an alternative automatic segmentation is often used. However, it does not guarantee the quality and could lead to improper or failed segmented boundaries due to differences in MRI acquisition parameters across imaging centers, as segmentation is an ill-defined problem. Analogous to visual object tracking and classification, this paper shifts the paradigm by training a classifier using tumor bounding box areas in MR images. The aim of our study is to see whether it is possible to replace GT tumor areas by tumor bounding box areas (e.g. ellipse shaped boxes) for classification without a significant drop in performance.

Method

In patients with diffuse gliomas, training a deep learning classifier for subtype prediction by employing tumor regions of interest (ROIs) using ellipse bounding box versus manual annotated data. Experiments were conducted on two datasets (US and TCGA) consisting of multi-modality MRI scans where the US dataset contained patients with diffuse low-grade gliomas (dLGG) exclusively.

Results

Prediction rates were obtained on 2 test datasets: 69.86% for 1p/19q codeletion status on US dataset and 79.50% for IDH mutation/wild-type on TCGA dataset. Comparisons with that of using annotated GT tumor data for training showed an average of 3.0% degradation (2.92% for 1p/19q codeletion status and 3.23% for IDH genotype).

Conclusion

Using tumor ROIs, i.e., ellipse bounding box tumor areas to replace annotated GT tumor areas for training a deep learning scheme, cause only a modest decline in performance in terms of subtype prediction. With more data that can be made available, this may be a reasonable trade-off where decline in performance may be counteracted with more data.

The Importance of Shared Decision-Making for Patients with Glioblastoma

Navigating care for patients with cancer can be overwhelming considering the multiple specialists they encounter and the numerous decisions they must make. For patients with glioblastoma (GBM), management is further complicated by a poor prognosis, feelings of isolation, urgency to treat, and cognitive decline associated with this rare and progressive disease. For these reasons, it is imperative that shared decision-making (SDM) be integrated into standard practice to ensure that the risks and benefits of all treatments are discussed and weighed with the patient's expectations and goals in mind. In this manuscript, the importance of SDM in GBM and the potential benefits to the practice and patient are discussed from the unique perspective of advocacy leaders. Their insights from interactions with patients and caregivers provide a template for empowering patients, improving patient-physician communication and understanding, and reducing patient and caregiver anxieties. Ultimately, increased SDM may lead to a better quality of life and improved treatment outcomes.
