Knowledge and thresholds for palliative care and surgery among healthcare providers caring for adults with serious illness.

Introduction: Timely palliative care and surgical interventions improve symptoms, health-related quality of life (HRQoL), and reduce medical cost for seriously ill adults at end of life (EOL). However, there is still poor delivery and underutilization of these palliative services. We hypothesize that the sub-optimal delivery is due to limited understanding among healthcare providers. Methods: A nationwide cross-sectional online survey was conducted among primary and tertiary healthcare providers. The survey assessed challenges faced, palliative education, confidence in managing palliative patients, and knowledge on palliative surgery. Overall palliative care awareness and knowledge was assessed using a 6-point score. Likelihood of considering various palliative interventions at EOL was also determined using a threshold score (higher score = higher threshold). Results: There were 145 healthcare providers who completed the survey (81.9% response rate); majority reported significant challenges in providing various aspects of palliative care: 57% (n = 82) in the provision of emotional support. Sixty-nine percent (n = 97) in managing social issues, and 71% (n = 103) in managing family expectations. Most expressed inadequate palliative care training in both under-graduate and post-graduate training and lack confidence in managing EOL issues. Up to 57% had misconceptions regarding potential benefits, morbidity and mortality after palliative surgery. In general, most providers had high thresholds for Intensive Care Unit admissions and palliative surgery, and were more likely to recommend endoscopic or interventional radiology procedures at EOL. Conclusion: Healthcare providers in Singapore have poor knowledge and misconceptions about palliative care and surgery. Improving awareness and education among those caring for seriously ill adults is essential.

Empathy Levels Among Healthcare Professionals: An Asian Multi-professional Cross-Sectional Study.

BACKGROUND: The aim of the study was to measure empathy in healthcare professionals in Singapore and to compare the scores between the different professions: doctors, nurses, and allied health professionals. METHODS: An online survey questionnaire was conducted using the Jefferson Scale of Empathy (JSE) from July 2019 to January 2020. The total JSE score was calculated and compared among the different groups. Multiple linear regression was performed to assess predictors of total empathy scores for groups with statistically lower scores. RESULTS: The survey was completed by 4,188 healthcare professionals (doctors (n=569, 13.6%), nurses (n=3032, 72.4%), and allied health professionals (n=587, 14.0%)) out of the 9,348-strong survey population, with a response rate of 44.8%. The study revealed a mean empathy score (SD) of 103.6 (15.6) for the cohort. The mean empathy score (SD) was 112.3 (14.7), 101.3 (15.2), and 107.0 (15.0), respectively for doctors, nurses, and allied health professionals. These were statistically significantly different among the groups (p< 0.0001), with nurses scoring significantly lower than either doctors (p< 0.0001) or allied health professionals (p< 0.0001). Multiple linear regression showed that age < 30 years old, male gender, Malay ethnicity, and working in a hospital setting were associated with significantly lower empathy scores in the nursing group. CONCLUSION: Nurses in Singapore had significantly lower empathy scores compared to doctors and allied health professionals. Further research on the underlying causes should be undertaken and measures to improve empathy among Singapore nursing staff should be explored and implemented.

Public sentiments and the influence of information-seeking preferences on knowledge, attitudes, death conversation, and receptiveness toward palliative care: results from a nationwide survey in Singapore.

Background: Low awareness about palliative care among the global public and healthcare communities has been frequently cited as a persistent barrier to palliative care acceptance. Given that knowledge shapes attitudes and encourages receptiveness, it is critical to examine factors that influence the motivation to increase knowledge. Health information-seeking from individuals and media has been identified as a key factor, as the process of accessing and interpreting information to enhance knowledge has been shown to positively impact health behaviours. Objective: Our study aimed to uncover public sentiments toward palliative care in Singapore. A conceptual framework was additionally developed to investigate the relationship between information-seeking preferences and knowledge, attitudes, receptiveness of palliative care, and comfort in death discussion. Design and Methods: A nationwide survey was conducted in Singapore with 1226 respondents aged 21 years and above. The data were analysed through a series of hierarchical multiple regression to examine the hypothesised role of information-seeking sources as predictors. Results: Our findings revealed that 53% of our participants were aware of palliative care and about 48% were receptive to receiving the care for themselves. It further showed that while information-seeking from individuals and media increases knowledge, attitudes and receptiveness to palliative care, the comfort level in death conversations was found to be positively associated only with individuals, especially healthcare professionals. Conclusion: Our findings highlight the need for public health authorities to recognize people's deep-seated beliefs and superstitions surrounding the concept of mortality. As Asians view death as a taboo topic that is to be avoided at all costs, it is necessary to adopt multipronged communication programs to address those fears. It is only when the larger communicative environment is driven by the media to encourage public discourse, and concurrently supported by timely interventions to trigger crucial conversations on end-of-life issues between individuals, their loved ones, and the healthcare team, can we advance awareness and benefits of palliative care among the public in Singapore.

A nationwide survey to understand public sentiments and the extent that information-seeking preferences can increase knowledge, attitudes, receptiveness of palliative care, and comfort level in death discussion in Singapore Low awareness of palliative care is a barrier that persistently hinders palliative care acceptance among populations in developing and developed countries. As knowledge shapes attitudes and encourages receptiveness, it is vital that researchers uncover factors that influence the motivation to increase knowledge. Health information-seeking is a factor that deserves greater attention in palliative care research because the process of seeking out information on health concerns from other people or the media can greatly increase individuals' knowledge. As such, this nationwide survey involving 1226 participants was carried out in Singapore to understand the public sentiments toward palliative care. It further statistically analyzed if information-seeking (from individuals and the media) will increase knowledge, attitudes, receptiveness toward palliative care, and comfort level in death discussion. Our findings indicated that 53% of our participants were aware of palliative care and about 48% were receptive to receiving the care for themselves. Furthermore, while information-seeking from individuals and media increases knowledge, attitudes, and receptiveness to palliative care, people are only comfortable to engage in death discussion with individuals, especially healthcare professionals. Exposure to media alone is not enough to encourage individuals to want to talk about end-of-life issues including palliative care. As Asians view death as a taboo topic, it is important for public health authorities to recognize people's deep-seated beliefs and superstitions surrounding the concept of mortality. A multipronged communication program is therefore needed to address these fears. It is only when the larger communicative environment driven by the media to encourage public discourse, and concurrently supported by timely interventions to trigger crucial conversations on end-of-life issues between individuals, their loved ones, and the healthcare team, can we advance awareness and benefits of palliative care among the public in Singapore.

Physician-patient boundaries in palliative care.

BACKGROUND: Nurturing effective physician-patient relationships is essential to the provision of patient-centred care. Palliative care physicians may apply boundary-crossings or breaches in professional standards to nurture effective physician-patient relationships. Being highly individualized and shaped by the physician's narratives, clinical experience, and contextual considerations, boundary-crossings are susceptible to ethical and professional violations. To better appreciate this concept, we employ the Ring Theory of Personhood (RToP) to map the effects of boundary-crossings on the physician's belief systems. METHODS: As part of the Tool Design SEBA methodology, a Systematic Evidence-Based Approach (SEBA) guided systematic scoping review was employed to guide the design of a semi-structured interview questionnaire with palliative care physicians. The transcripts were simultaneously content and thematically analysed. The themes and categories identified were combined using the Jigsaw Perspective and the resulting domains formed the basis for the discussion. RESULTS: The domains identified from the 12 semi-structured interviews were catalysts and boundary-crossings. Boundary-crossings attempt to address threats to a physician's belief systems (catalysts) and are highly individualized. Employ of boundary-crossings depend on the physician's sensitivity to these 'catalysts', their judgement and willingness to act, and their ability to balance various considerations and reflect on their actions and their ramifications. These experiences reshape belief systems, understandings of boundary-crossings and may influence decision-making and practice, underscoring the potential for greater professional breaches when unchecked. CONCLUSION: Underlining its longitudinal effects, the Krishna Model underscores the importance of longitudinal support, assessment and oversight of palliative care physicians, and lays the foundation for a RToP-based tool to be employed within portfolios.

Evidence-guided approach to portfolio-guided teaching and assessing communications, ethics and professionalism for medical students and physicians: a systematic scoping review.

OBJECTIVES: Guiding the development of longitudinal competencies in communication, ethics and professionalism underlines the role of portfolios to capture and evaluate the multiple multisource appraisals and direct personalised support to clinicians. However, a common approach to these combined portfolios continues to elude medical practice. A systematic scoping review is proposed to map portfolio use in training and assessments of ethics, communication and professionalism competencies particularly in its inculcation of new values, beliefs and principles changes attitudes, thinking and practice while nurturing professional identity formation. It is posited that effective structuring of portfolios can promote self-directed learning, personalised assessment and appropriate support of professional identity formation. DESIGN: Krishna's Systematic Evidence-Based Approach (SEBA) is employed to guide this systematic scoping review of portfolio use in communication, ethics and professionalism training and assessment. DATA SOURCES: PubMed, Embase, PsycINFO, ERIC, Scopus and Google Scholar databases. ELIGIBILITY CRITERIA: Articles published between 1 January 2000 and 31 December 2020 were included. DATA EXTRACTION AND SYNTHESIS: The included articles are concurrently content and thematically analysed using the split approach. Overlapping categories and themes identified are combined using the jigsaw perspective. The themes/categories are compared with the summaries of the included articles in the funnelling process to ensure their accuracy. The domains identified form the framework for the discussion. RESULTS: 12 300 abstracts were reviewed, 946 full-text articles were evaluated and 82 articles were analysed, and the four domains identified were indications, content, design, and strengths and limitations. CONCLUSIONS: This review reveals that when using a consistent framework, accepted endpoints and outcome measures, longitudinal multisource, multimodal assessment data fashions professional and personal development and enhances identity construction. Future studies into effective assessment tools and support mechanisms are required if portfolio use is to be maximised.

Painting and Poetry From a Bereaved Family and the Caring Physician.

This is a case description and personal account shared by a palliative care physician whose team provided specialist palliative care support to a patient who attempted immolation. This case depicts a family at risk of complicated grief due to the violent nature of self-inflicted burns and the lingering social stigmatization of suicide. Here, we explore important psycho-emotional considerations and share our experience using art and poetry to build therapeutic connections with the grieving family.

A systematic scoping review on patients' perceptions of dignity.

BACKGROUND: A socioculturally appropriate appreciation of dignity is pivotal to the effective provision of care for dying patients. Yet concepts of dignity remain poorly defined. To address this gap in understanding and enhance dignity conserving end-of-life care, a review of current concepts of dignity is proposed. METHODS: To address its primary research question "How do patients conceive the concept of dignity at the end of life?", this review appraises regnant concepts and influences of dignity, and evaluates current dignity conserving practices. To enhance accountability, transparency and reproducibility, this review employs the Ring Theory of Personhood (RToP) as its theoretical lens to guide a Systematic Evidence Based Approach guided Systematic Scoping Review (SSR in SEBA) of patient perspectives of dignity. Three independent teams of reviewers independently analysed included articles from a structured search of PubMed, Embase, PsycINFO, Scopus, CINAHL and Cochrane Databases using thematic and content analyses. The themes and categories identified were compared and combined using the Funnelling Process to create domains that guide the discussion that follows. RESULTS: Seventy-eight thousand five hundred seventy-five abstracts were identified, 645 articles were reviewed, and 127 articles were included. The three domains identified were definitions of dignity, influences upon perceptions of dignity, and dignity conserving care. CONCLUSIONS: This SSR in SEBA affirms the notion that dignity is intimately entwined with self-concepts of personhood and that effective dignity conserving measures at the end of life must be guided by the patient's concept of dignity. This SSR in SEBA posits that such personalised culturally sensitive, and timely support of patients, their family and loved ones may be possible through the early and longitudinal application of a RToP based tool.

A systematic scoping review of communication skills training in medical schools between 2000 and 2020.

BACKGROUND: Communication skills training (CST) remains poorly represented and prioritised in medical schools despite its importance. A systematic scoping review (SSR) of CST is proposed to better appreciate current variability in their structure, content, and assessment. This is to guide their future design in medical school curricula. METHODS: The Systematic Evidence-Based Approach (SEBA) was used to guide concurrent SSRs of teaching and assessment in CST. After independent database searches, concurrent thematic and content analysis of included articles were conducted separately. Resultant themes/categories were combined via the jigsaw perspective to provide a more holistic view of the data. These were then compared to tabulated summaries of the included articles to create funnelled domains. RESULTS: 52,300 papers were identified, 150 full-text articles included, and four funnelled domains were identified: Indications, Design, Assessment, and Barriers and Enablers of CST. CSTs confer numerous benefits to physicians and patients. It saw increased confidence, improved diagnostic capabilities and better clinical management, as well as greater patient satisfaction and treatment compliance. Skills may be divided into core, prerequisite competencies, and advanced skills pertinent to more challenging and nuanced scenarios - such as population or setting-specific situations. CST teaching and assessment modalities were found to align with Miller's Pyramid, with didactic teaching gradually infused with experiential approaches to enhance their understanding and integration. A plethora of CST frameworks, teaching and assessment methods were identified and are presented together. CONCLUSION: While variable in approach, content and assessment, CST in medical schools often employ stage-based curricula to instil competency-based topics of increasing complexity throughout medical school education. This process builds on the application of prior knowledge and skills, influencing practice and, potentially, the students' professional identity formation. In addition, the institution plays a critical role in overseeing training, ensuring longitudinal guidance and holistic assessments of the students' progress.

A Systematic Scoping Review on Pedagogical Strategies of Interprofessional Communication for Physicians in Emergency Medicine.

BACKGROUND: Interprofessional communication (IPC) is integral to interprofessional teams working in the emergency medicine (EM) setting. Yet, the coronavirus disease 2019 pandemic has laid bare gaps in IPC knowledge, skills and attitudes. These experiences underscore the need to review how IPC is taught in EM. PURPOSE: A systematic scoping review is proposed to scrutinize accounts of IPC programs in EM. METHODS: Krishna's Systematic Evidence-Based Approach (SEBA) is adopted to guide this systematic scoping review. Independent searches of ninedatabases (PubMed, Embase, CINAHL, Scopus, PsycINFO, ERIC, JSTOR, Google Scholar and OpenGrey) and "negotiated consensual validation" were used to identify articles published between January 1, 2000 and December 31, 2020. Three research teams reviewed the data using concurrent content and thematic analysis and independently summarized the included articles. The findings were scrutinized using SEBA's jigsaw perspective and funneling approach to provide a more holistic picture of the data. IN TOTAL: 18,809 titles and abstracts were identified after removal of duplicates, 76 full-text articles reviewed, and 19 full-text articles were analyzed. In total, four themes and categories were identified, namely: (a) indications and outcomes, (2) curriculum and assessment methods, (3) barriers, and (4) enablers. CONCLUSION: IPC training in EM should be longitudinal, competency- and stage-based, underlining the need for effective oversight by the host organization. It also suggests a role for portfolios and the importance of continuing support for physicians in EM as they hone their IPC skills. HIGHLIGHTS: • IPC training in EM is competency-based and organized around stages.• IPC competencies build on prevailing knowledge and skills.• Longitudinal support and holistic oversight necessitates a central role for the host organization.• Longitudinal, robust, and adaptable assessment tools in the EM setting are necessary and may be supplemented by portfolio use.

Teaching and assessing communication skills in the postgraduate medical setting: a systematic scoping review.

BACKGROUND: Poor communication skills can potentially compromise patient care. However, as communication skills training (CST) programs are not seen as a priority to many clinical departments, there is a discernible absence of a standardised, recommended framework for these programs to be built upon. This systematic scoping review (SSR) aims to gather prevailing data on existing CSTs to identify key factors in teaching and assessing communication skills in the postgraduate medical setting. METHODS: Independent searches across seven bibliographic databases (PubMed, PsycINFO, EMBASE, ERIC, CINAHL, Scopus and Google Scholar) were carried out. Krishna's Systematic Evidence-Based Approach (SEBA) was used to guide concurrent thematic and content analysis of the data. The themes and categories identified were compared and combined where possible in keeping with this approach and then compared with the tabulated summaries of the included articles. RESULTS: Twenty-five thousand eight hundred ninety-four abstracts were identified, and 151 articles were included and analysed. The Split Approach revealed similar categories and themes: curriculum design, teaching methods, curriculum content, assessment methods, integration into curriculum, and facilitators and barriers to CST. Amidst a wide variety of curricula designs, efforts to develop the requisite knowledge, skills and attitudes set out by the ACGME current teaching and assessment methods in CST maybe categorised into didactic and interactive methods and assessed along Kirkpatrick's Four Levels of Learning Evaluation. CONCLUSIONS: A major flaw in existing CSTs is a lack of curriculum structure, focus and standardisation. Based upon the findings and current design principles identified in this SSR in SEBA, we forward a stepwise approach to designing CST programs. These involve 1) defining goals and learning objectives, 2) identifying target population and ideal characteristics, 3) determining curriculum structure, 4) ensuring adequate resources and mitigating barriers, 5) determining curriculum content, and 6) assessing learners and adopting quality improvement processes.

Teaching Communication Micro-Skills to Cardiologists Managing Seriously Ill Patients in Asia: Challenges Encountered Amidst the COVID-19 Pandemic and Future Perspectives.

Background Patients with advanced cardiac conditions value effective symptom control and empathic communication with their doctors. However, studies have shown that empathic communication with seriously ill patients does not occur adequately in cardiology. Therefore, we piloted a program for teaching communication skills in a bite-sized manner. The primary aim of the research was to understand the feasibility and acceptability of the training program and to perform a preliminary evaluation of its efficacy. Methodology Clinicians were recruited from the cardiology unit of a tertiary hospital in Singapore. Patients were also recruited for the audio recording of clinic consults. Recruited patients had to have a chronic cardiac condition and be deemed at risk of dying within one year. We utilized a pre-post intervention design. Prior to the educational intervention, clinicians were asked to audio record a single clinic consult at baseline. They were then asked to participate in a training program that consisted of video-annotated presentations and role-play scenarios. Subsequently, the audio recordings of their clinic consults with seriously ill patients were recorded. The audio recordings were evaluated by trainers and used for feedback with clinicians. Data on the completion rate of the training program were collected. In addition, changes in the clinicians' self-rated communication skills and views on the acceptability and relevance of the training program were collected. Results Overall, five of the six clinicians (83.3%) completed all sessions in the program. One clinician only completed four out of the five sessions in the program. Clinicians deemed the program acceptable and relevant and found audio recordings to be useful for reflective learning. There was an improvement in the clinicians' self-assessed competency. However, the planned number of audio recordings could not be completed due to the coronavirus disease 2019 pandemic. Conclusions The pilot training program was acceptable and relevant for the participants. However, it will require adaptation to allow it to be transferrable and scalable to all settings, especially in situations that limit prolonged face-to-face contact.

Operationalization of critical care triage during a pandemic surge using protocolized communication and integrated supportive care.

Triage becomes necessary when demand for intensive care unit (ICU) resources exceeds supply. Without triage, there is a risk that patients will be admitted to the ICU in the sequence that they present, disadvantaging those who either present later or have poorer access to healthcare. Moreover, if the patients with the best prognosis are not allocated life support, there is the possibility that overall mortality will increase. Before formulating criteria, principles such as maximizing lives saved and fairness ought to have been agreed upon to guide decision-making. The triage process is subdivided into three parts, i.e., having explicit inclusion/exclusion criteria for ICU admission, prioritization of patients for allocation to available beds, and periodic reassessment of all patients already admitted to the ICU. Multi-dimensional criteria offer more holistic prognostication than only using age cutoffs. Appointed triage officers should also be enabled to make data-driven decisions. However, the process does not merely end with an allocation decision being made. Any decision has to be sensitively and transparently communicated to the patient and family. With infection control measures, there are challenges in managing communication and the psychosocial distress of dying alone. Therefore, explicit video call protocols and social services expertise will be necessary to mitigate these challenges. Besides symptom management and psychosocial management, supportive care teams play an integral role in coordination of complex cases. This scoping review found support for the three-pronged, triage-communication-supportive care approach to facilitate the smooth operationalization of the triage process in a pandemic.

Enhancing Interprofessional Communications Training in Internal Medicine. Lessons Drawn From a Systematic Scoping Review From 2000 to 2018.

INTRODUCTION: Interprofessional communication (IPC) enhances patient experiences and outcomes and improves well-being and satisfaction among health care professionals. This scoping review seeks to guide design of IPC training in internal medicine. METHODS: The framework of Arksey and O'Malley (2005) guided this systematic scoping review in internal medicine across PubMed, Embase, CINAHL, Scopus, PsycINFO, ERIC, JSTOR, and Google Scholar databases for publications from the years 2000 to 2018. RESULTS: Twenty-two thousand eight hundred seventy-four abstracts were retrieved, 326 full-text articles were reviewed, and 32 articles were included. The themes identified using directed content analysis were indications for an IPC program, training stages, and obstacles. The rationale for IPC programs was to improve interprofessional teamwork and enhance patient care. IPC training occurs in five stages beginning with instilling the role, value, and skills behind IPC and gradually practicing these skills within the clinical setting. The challenges to IPC highlight the need to confront workplace hierarchies and the lack of resources. DISCUSSION: The findings of this systematic scoping review also serve to underscore the importance of understanding, evaluating, and influencing the clinical environment and the work environment and the need for new assessment tools that will guide the individualized, longitudinal, competency-based learning process that underpins IPC training.

Addressing the Needs of Migrant Workers in ICUs in Singapore.

BACKGROUND: With nearly 400 000 migrant workers in Singapore, many from Bangladesh, India and Myanmar, language and cultural barriers posed a great many challenges during the COVID-19 pandemic. This was especially so as majority of the COVID-19 clusters in Singapore emerged from their communal dormitories. With concerns arising as to how this minority group could be best cared for in the intensive care units, the need for medical interpreters became clear. MAIN: In response, the Communication and Supportive Care (CSC) workgroup at the Singapore General Hospital developed the 'Medical Interpreters Training for ICU Conversations' program. Led by a medical social worker-cum-ethicist and 2 palliative care physicians, twenty volunteers underwent training. The program comprised of 4 parts. Firstly, volunteers were provided with an overview of challenges within the COVID-19 isolation ICU environment. Discussed in detail were common issues between patients and families, forms of distress faced by healthcare workers, family communication modality protocols, and the sociocultural demographics of Singapore's migrant worker population. Secondly, key practice principles and 'Do's/Don'ts' in line with the ethical principles of medical interpretation identified by the California Healthcare Interpreters Association were shared. Thirdly, practical steps to consider before, during and at the end of each interpretation session were foregrounded. Lastly, a focus group discussion on the complexities of ICU cases and their attending issues was conducted. Targeted support was further provided in response to participant feedback and specific issues raised. CONCLUSION: As a testament to its efficacy, the program has since been extended to the general wards and the Ministry of Health in Singapore has further commissioned similar programs in various hospitals. In-depth training on the fundamentals of medical terminology, language and cultural competency should be provided to all pertinent healthcare workers and hospitals should consider hiring medical interpreters in permanent positions.

Palliative and end-of-life care in rheumatology: High symptom prevalence and unmet needs.

OBJECTIVES: To determine the extent of end-of-life suffering and predictors of high symptom prevalence in the last one year of life in patients with systemic rheumatic diseases (SRDs) and the extent of supportive care received. METHODS: We identified adult patients with SRDs who died between 1 April 2006 and 1 April 2016. We collected data within 1 year before their death, on the following: (i) cumulative symptom prevalence, (ii) rates of Advance Care Planning (ACP), Do-Not-Resuscitate (DNR) orders and referral to a palliative physician. We analyzed the predictors of total symptom prevalence and palliative physician referral. RESULTS: Of the 161 patients studied, 34.2% had rheumatoid arthritis and 21.6% had systemic lupus erythematosus. Pain (81.4%), anorexia (80.1%) and dyspnea (77%) afflicted the majority of patients. On multivariate analysis, patients of the following profile had higher total symptom prevalence: (i) older age (ß = 0.027, SE = 0.013, p = 0.044); (ii) more comorbidities measured by the Charlson Comorbidity Index (ß = 0.192, SE = 0.159, p = 0.044); (iii) more admissions (ß = 0.263, SE = 0.090, p = 0.004) and (iv) recurrent infections (ß = 0.923, SE = 0.423, p = 0.031). Five patients (3.1%) received ACP and 25 (15.5%) were referred to a palliative physician. The median time between referral to palliative medicine and death was 8 days (IQR0-19). Of the 106 (67.5%) who had DNR orders, the median time between DNR and death was 3 days (IQR 0-10). CONCLUSIONS: Palliative and supportive care is relevant to patients with SRDs at the end-of-life. These patients experienced high physical suffering, particularly those who were elderly, with more comorbidities, hospital admissions and recurrent infections. Rheumatologists and physicians caring for patients with SRDs must be empowered to provide supportive care to these patients at the last phase of life, particularly by facilitating early ACP.

The Value of T-Cell Receptor γ (TRG) Clonality Evaluation by Next-Generation Sequencing in Clinical Hematolymphoid Tissues.

OBJECTIVES: To evaluate feasibility of assessing T-cell receptor γ (TRG) clonality by next-generation sequencing (NGS) in hematolymphoid tissues. METHODS: We evaluated TRG clonality using NGS and polymerase chain reaction (PCR) assays in blood, bone marrow, and formalin-fixed, paraffin-embedded tissues in 41 archived cases, including 21 benign cases with no history of any lymphoproliferative disorders (LPDs), 16 LPDs (nine mature T-cell neoplasms, seven mature B-cell neoplasms and immune dysregulation-associated LPDs), and four atypical LPDs from 22 females and 19 males with a median age of 58 (range, 9-87) years. RESULTS: (1) NGS analyzed TRG sequence and peak ratios, and it had a greater sensitivity than PCR. (2) NGS identified small clones, including biallelic or monoallelic, and minimum clonal percentages (range, ~2.4% to ~69%) within all T cells. (3) We provide our strategy and criteria for evaluating NGS results. (4) We describe every case, with definitive evaluation of TRG clonality in 100% cases by NGS. CONCLUSIONS: TRG clonality evaluation by NGS provides greater clinical utility than PCR.

Variation in physician recommendations, knowledge and perceived roles regarding provision of end-of-life care.

BACKGROUND: There is high variability in end-of-life (EOL) treatments. Some of this could be due to differences in physician treatment recommendations, their knowledge/attitude regarding palliative care, and their perceived roles in treating patients with advanced serious illness (ASI). Thus, the objective of this paper was to identify potential variation in physician recommendations, their knowledge/attitude regarding palliative care and perceived roles in treating ASI patients. METHODS: A cross-sectional survey consisting of vignettes describing patient characteristics that varied by age, expected survival, cognitive status and treatment costs and asked physicians whether they would recommend life-extending treatments for each scenario, was administered to 285 physicians who treat ASI patients in Singapore. Physicians were also assessed on their knowledge/attitude in palliative care. They were administered a best-worst scaling exercise requiring them to select their most and least important role as a physician caring for an ASI patient. RESULTS: There was a wide variation in physician recommendations for life-extending treatments for patients with similar profiles, which can partly be attributed to physician characteristics (years of experience and place of training). Only about one-fourth of the physicians answered all knowledge/attitude questions correctly. Statements assessing knowledge/attitude regarding pain management had the fewest correct responses. The most important perceived role regarding provision of EOL care concerned symptom management. CONCLUSIONS: Results suggest that variation in physician treatment recommendations may be partly related to their own characteristics, raising concerns regarding the EOL care being provided to patients. Efforts should be made to better understand this variation and to provide the physicians with additional training in key aspects of palliative care management.
