How Physicians are Trained to Interact With the Dying: A Thematic Analysis of Medical Student Exposures to End-Of-Life Cases.

Physicians-in-training feel uncomfortable coping with the grief they experience while delivering end-of-life care, and medical schools offer minimal formal curricular offerings on end of life care. Few studies have identified what experiences medical students have with death while training or what lessons they are being taught by more senior physicians at bedside. This qualitative study conducted semi-structured interviews prior to and six months into the medical school clinical year. Our goal was to identify when students were encountering seriously ill/dying patients and what informal education students received about caring for dying patients. Descriptive statistics showed the majority of the encounters the students had with seriously ill or dying patients were in the hospital-based medicine setting. A minority of students participated in debriefs about end-of-life care with their care teams after the events. Thematic analysis showed significant heterogeneity in students' exposure and responses to patient deaths.

Developing a conceptual, reproducible, rubric-based approach to consent and result disclosure for genetic testing by clinicians with minimal genetics background.

PURPOSE: In response to genetic testing being widely ordered by nongenetics clinicians, the Consent and Disclosure Recommendations (CADRe) Workgroup of the Clinical Genome Resource (ClinGen; clinicalgenome.org ) developed guidance to facilitate communication about genetic testing and efficiently improve the patient experience. Considering ethical, legal, and social implications, and medical factors, CADRe developed and pilot tested two rubrics addressing consent for genetic testing and results disclosure. The CADRe rubrics allow for adjusting the communication approach based on circumstances specific to patients and ordering clinicians. METHODS: We present results of a formative survey of 66 genetics clinicians to assess the consent rubric for nine genes (MLH1, CDH1, TP53, GJB2, OTC; DMD, HTT, and CYP2C9/VKORC1). We also conducted interviews and focus groups with family and patient stakeholders (N = 18), nongenetics specialists (N = 27), and genetics clinicians (N = 32) on both rubrics. RESULTS: Formative evaluation of the CADRe rubrics suggests key factors on which to make decisions about consent and disclosure discussions for a "typical" patient. CONCLUSION: We propose that the CADRe rubrics include the primary issues necessary to guide communication recommendations, and are ready for pilot testing by nongenetics clinicians. Consultation with genetics clinicians can be targeted toward more complex or intensive consent and disclosure counseling.

Development of Clinical Domain Working Groups for the Clinical Genome Resource (ClinGen): lessons learned and plans for the future.

The Clinical Genome Resource (ClinGen) is supported by the National Institutes of Health (NIH) to develop expertly curated and freely accessible resources defining the clinical relevance of genes and variants for use in precision medicine and research. To facilitate expert input, ClinGen has formed Clinical Domain Working Groups (CDWGs) to leverage the collective knowledge of clinicians, laboratory diagnosticians, and researchers. In the initial phase of ClinGen, CDWGs were launched in the cardiovascular, hereditary cancer, and inborn errors of metabolism clinical fields. These early CDWGs established the infrastructure necessary to implement standardized processes developed or adopted by ClinGen working groups for the interpretation of gene-disease associations and variant pathogenicity, and provided a sustainable model for the formation of future disease-focused curation groups. The establishment of CDWGs requires recruitment of international experts to broadly represent the interests of their field and ensure that assertions made are reliable and widely accepted. Building on the successes, challenges, and trade-offs made in establishing the original CDWGs, ClinGen has developed standard operating procedures for the development of CDWGs in new clinical domains, while maximizing efforts to scale up curation and facilitate involvement of external groups who wish to utilize ClinGen methods and infrastructure for expert curation.

The clinical imperative for inclusivity: Race, ethnicity, and ancestry (REA) in genomics.

The Clinical Genome Resource (ClinGen) Ancestry and Diversity Working Group highlights the need to develop guidance on race, ethnicity, and ancestry (REA) data collection and use in clinical genomics. We present quantitative and qualitative evidence to characterize: (1) acquisition of REA data via clinical laboratory requisition forms, and (2) information disparity across populations in the Genome Aggregation Database (gnomAD) at clinically relevant sites ascertained from annotations in ClinVar. Our requisition form analysis showed substantial heterogeneity in clinical laboratory ascertainment of REA, as well as marked incongruity among terms used to define REA categories. There was also striking disparity across REA populations in the amount of information available about clinically relevant variants in gnomAD. European ancestral populations constituted the majority of observations (55.8%), allele counts (59.7%), and private alleles (56.1%) in gnomAD at 550 loci with "pathogenic" and "likely pathogenic" expert-reviewed variants in ClinVar. Our findings highlight the importance of implementing and supporting programs to increase diversity in genome sequencing and clinical genomics, as well as measuring uncertainty around population-level datasets that are used in variant interpretation. Finally, we suggest the need for a standardized REA data collection framework to be developed through partnerships and collaborations and adopted across clinical genomics.

ClinGen Variant Curation Expert Panel experiences and standardized processes for disease and gene-level specification of the ACMG/AMP guidelines for sequence variant interpretation.

Genome-scale sequencing creates vast amounts of genomic data, increasing the challenge of clinical sequence variant interpretation. The demand for high-quality interpretation requires multiple specialties to join forces to accelerate the interpretation of sequence variant pathogenicity. With over 600 international members including clinicians, researchers, and laboratory diagnosticians, the Clinical Genome Resource (ClinGen), funded by the National Institutes of Health, is forming expert groups to systematically evaluate variants in clinically relevant genes. Here, we describe the first ClinGen variant curation expert panels (VCEPs), development of consistent and streamlined processes for establishing new VCEPs, and creation of standard operating procedures for VCEPs to define application of the ACMG/AMP guidelines for sequence variant interpretation in specific genes or diseases. Additionally, ClinGen has created user interfaces to enhance reliability of curation and a Sequence Variant Interpretation Working Group (SVI WG) to harmonize guideline specifications and ensure consistency between groups. The expansion of VCEPs represents the primary mechanism by which curation of a substantial fraction of genomic variants can be accelerated and ultimately undertaken systematically and comprehensively. We welcome groups to utilize our resources and become involved in our effort to create a publicly accessible, centralized resource for clinically relevant genes and variants.

Evidence-based assessments of clinical actionability in the context of secondary findings: Updates from ClinGen's Actionability Working Group.

The use of genome-scale sequencing allows for identification of genetic findings beyond the original indication for testing (secondary findings). The ClinGen Actionability Working Group's (AWG) protocol for evidence synthesis and semi-quantitative metric scoring evaluates four domains of clinical actionability for potential secondary findings: severity and likelihood of the outcome, and effectiveness and nature of the intervention. As of February 2018, the AWG has scored 127 genes associated with 78 disorders (up-to-date topics/scores are available at www.clinicalgenome.org). Scores across these disorders were assessed to compare genes/disorders recommended for return as secondary findings by the American College of Medical Genetics and Genomics (ACMG) with those not currently recommended. Disorders recommended by the ACMG scored higher on outcome-related domains (severity and likelihood), but not on intervention-related domains (effectiveness and nature of the intervention). Current practices indicate that return of secondary findings will expand beyond those currently recommended by the ACMG. The ClinGen AWG evidence reports and summary scores are not intended as classifications of actionability, rather they provide a resource to aid decision makers as they determine best practices regarding secondary findings. The ClinGen AWG is working with the ACMG Secondary Findings Committee to update future iterations of their secondary findings list.

Early biochemical response to parathyroidectomy for primary hyperparathyroidism and its predictive value for recurrent hypercalcemia and recurrent primary hyperparathyroidism.

BACKGROUND: The traditional definition of cure after parathyroidectomy (PTX) for primary hyperparathyroidism is normocalcemia. Our hypothesis was that early postoperative levels of serum calcium and parathyroid hormone after PTX would have predictive value for later recurrence. METHODS: We performed a retrospective study of 1,146 patients with primary hyperparathyroidism who underwent PTX and had long-term biochemical follow-up. The first postoperative serum level of calcium and parathyroid hormone values were used to categorize patients into the following four early biochemical response groups: (1) complete response (normal calcium and normal parathyroid hormone), (2) partial response with hyperparathormonemia (normal calcium and increased parathyroid hormone), (3) partial response with hypercalcemia (increased calcium and normal parathyroid hormone), and (4) non-response (increases in both calcium and parathyroid hormone). Incidences of recurrent hypercalcemia and recurrent primary hyperparathyroidism >6 months after operation were then analyzed. RESULTS: The overall rate of any elevated serum levels of calcium and any increase in serum levels of parathyroid hormone during >6-month follow-up was 9.8% (112 of 1146), with 6.6% (57 of 861) for group 1, 27% (35 of 129) for group 2, and 16% (20 of 127) for group 3 (P < .02). Partial biochemical responses with either increased serum calcium or increased parathyroid hormone levels were the strongest predictors of any episode of increased serum levels of calcium after 6 months and was associated with 2.7× to 4.3× the risk of recurrent primary hyperparathyroidism, respectively. CONCLUSION: This study demonstrates the importance of measuring parathyroid hormone in the early postoperative period to better predict later recurrent primary hyperparathyroidism.
