An economic evaluation of an early palliative care intervention among patients with advanced cancer.

BACKGROUND: Early integration of palliative care into oncology care has shown positive effects on patient symptoms and quality of life. It may also reduce health care costs. However given the heterogeneity of settings and interventions and the lack of information on the minimally effective dose for influencing care utilisation and costs, it remains uncertain whether early palliative care reduces costs. OBJECTIVES: We sought to determine whether an early palliative care intervention integrated in usual oncology care in a Swiss hospital setting reduced utilisation and costs of health care in the last month of life when compared with usual oncology care alone. METHODS: We performed a cost-consequences analysis alongside a multicentre trial. We extracted costs from administrative health insurance data and health care utilisation from family caregiver surveys to compare two study arms: usual oncology care and usual oncology care plus the palliative care intervention. The intervention consisted of a single-structured, multiprofessional conversation with the patient about symptoms, end-of-life decisions, network building and support for carers (SENS). The early palliative care intervention was performed within 16 weeks of the diagnosis of a tumour stage not amenable or responsive to curative treatment. RESULTS: We included 58 participants with advanced cancer in our economic evaluation study. Median overall health care costs in the last month of life were 7892 Swiss Francs (CHF) (interquartile range: CHF 5637-13,489) in the intervention arm and CHF 8492 [CHF 5411-12,012] in the control arm. The average total intervention treatment cost CHF 380 per patient. Integrating an early palliative care intervention into usual oncology care showed no significant difference in health care utilisation or overall health care costs between intervention and control arms (p = 0.98). CONCLUSION: Although early palliative care is often presented as a cost-reducing care service, we could not show a significant effect of the SENS intervention on health care utilisation and costs in the last month of life. However, it may be that the intervention was not intensive enough, the timeframe too short or the study population too small for measurable effects. Patients appreciated the intervention. Single-structured early palliative care interventions are easy to implement in clinical practice and present low treatment costs. Further research about the economic impact of early palliative care should focus on extracting large, detailed cost databases showing potential shifts in cost and cost-effectiveness.

Palliative sedation - revised recommendations.

Palliative sedation is defined as the monitored use of medications intended to induce a state of decreased or absent awareness (unconsciousness) to relieve the burden of otherwise intractable suffering in a manner ethically acceptable to the patient, their family, and healthcare providers. In Switzerland, the prevalence of continuous deep sedation until death increased from 4.7% in 2001 to 17.5% of all deceased in 2013, depending on the research method used and on regional variations. Yet, these numbers may be overestimated due to a lack of understanding of the term "continuous deep sedation" by for example respondents of the questionnaire-based study. Inadequately trained and inexperienced healthcare professionals may incorrectly or inappropriately perform palliative sedation due to uncertainties regarding its definitions and practice. Therefore, the expert members of the Bigorio group and the authors of this manuscript believe that national recommendations should be published and made available to healthcare professionals to provide practical, terminological, and ethical guidance. The Bigorio group is the working group of the Swiss Palliative Care Society whose task is to publish clinical recommendations at a national level in Switzerland. These recommendations aim to provide guidance on the most critical questions and issues related to palliative sedation. The Swiss Society of Palliative Care (palliative.ch) mandated a writing board comprising four clinical experts (three physicians and one ethicist) and two national academic experts to revise the 2005 Bigorio guidelines. A first draft was created based on a narrative literature review, which was internally reviewed by five academic institutions (Lausanne, Geneva, Bern, Zürich, and Basel) and the heads of all working groups of the Swiss Society of Palliative Care before finalising the guidelines. The following themes are discussed regarding palliative sedation: (a) definitions and clinical aspects, (b) the decision-making process, (c) communication with patients and families, (d) patient monitoring, (e) pharmacological approaches, and (f) ethical and controversial issues. Palliative sedation must be practised with clinical and ethical accuracy and competence to avoid harm and ethically questionable use. Specialist palliative care teams should be consulted before initiating palliative sedation to avoid overlooking other potential treatment options for the patient's symptoms and suffering.

Applications of Machine Learning in Palliative Care: A Systematic Review.

Objective: To summarize the available literature on using machine learning (ML) for palliative care practice as well as research and to assess the adherence of the published studies to the most important ML best practices. Methods: The MEDLINE database was searched for the use of ML in palliative care practice or research, and the records were screened according to PRISMA guidelines. Results: In total, 22 publications using machine learning for mortality prediction (n = 15), data annotation (n = 5), predicting morbidity under palliative therapy (n = 1), and predicting response to palliative therapy (n = 1) were included. Publications used a variety of supervised or unsupervised models, but mostly tree-based classifiers and neural networks. Two publications had code uploaded to a public repository, and one publication uploaded the dataset. Conclusions: Machine learning in palliative care is mainly used to predict mortality. Similarly to other applications of ML, external test sets and prospective validations are the exception.

Palliative care and COVID-19: a bibliometric analysis.

OBJECTIVE: To assess the impact of COVID-19 on the palliative care (PC) publication trend in the last 10 years and the collaboration between countries and main topics that were discussed in the papers. METHODS: We used Scopus to identify publications on PC between 2012 and 2021 and publications about PC and COVID-19 between 2020 and 2021. We used VOSviewer to assess the main topics using the keywords from the papers and to assess country collaboration. RESULTS: 1937 publications resulted. An increase in publications about PC was observed during the pandemic, only partially explained by OVID-19-related publications. Cancer-related PC publications were the ones with the most marked increase. We identified six clusters in the distribution of the keywords: bioethics, cancer, nursing home/telemedicine, public health, caring and PC following the WHO definition. The countries with higher number of publications were the United States and England. CONCLUSION: We showed an increase in the number of PC publications in the last 2 years that was only partially explained by COVID-19-related publications. Most of the publications increase was due to cancer-related publications, since, during the time of the pandemic, publications on cancer and PC increased markedly, while those on heart failure, lung disease and dementia, remained constant.

An online international comparison of palliative care identification in primary care using the Surprise Question.

BACKGROUND: The Surprise Question ('Would I be surprised if this patient died within 12 months?') identifies patients in the last year of life. It is unclear if 'surprised' means the same for each clinician, and whether their responses are internally consistent. AIM: To determine the consistency with which the Surprise Question is used. DESIGN: A cross-sectional online study of participants located in Belgium, Germany, Italy, The Netherlands, Switzerland and UK. Participants completed 20 hypothetical patient summaries ('vignettes'). Primary outcome measure: continuous estimate of probability of death within 12 months (0% [certain survival]-100% [certain death]). A threshold (probability estimate above which Surprise Question responses were consistently 'no') and an inconsistency range (range of probability estimates where respondents vacillated between responses) were calculated. Univariable and multivariable linear regression explored differences in consistency. Trial registration: NCT03697213. SETTING/PARTICIPANTS: Registered General Practitioners (GPs). Of the 307 GPs who started the study, 250 completed 15 or more vignettes. RESULTS: Participants had a consistency threshold of 49.8% (SD 22.7) and inconsistency range of 17% (SD 22.4). Italy had a significantly higher threshold than other countries (p = 0.002). There was also a difference in threshold levels depending on age of clinician, for every yearly increase, participants had a higher threshold. There was no difference in inconsistency between countries (p = 0.53). CONCLUSIONS: There is variation between clinicians regarding the use of the Surprise Question. Over half of GPs were not internally consistent in their responses to the Surprise Question. Future research with standardised terms and real patients is warranted.

Prevalence and characteristics of patients with heart failure needing palliative care.

BACKGROUND: Few hospitals and heart failure (HF) clinics offer concurrent palliative care (PC) together with life-prolonging therapies. To know the prevalence of patients in HF clinics needing PC and useful tools to recognize them are the first steps to extending PC in those settings. However, it is still unknown whether tools commonly used to identify patients with HF needing PC can correctly distinguish them. Two systematic reviews found that the NECesidades PALiativas (NECPAL) tool was one of the two most commonly used tools to asses PC needs in HF patients. Therefore, we assessed 1) the prevalence of PC needs in HF clinics according to the NECPAL tool, and 2) the characteristics of the patients identified as having PC; mainly, their quality of life (QoL), symptom burden, and psychosocial problems. METHODS: This cross-sectional study was conducted at two HF clinics in Colombia. We assessed the prevalence of PC in the overall sample and in subgroups according to clinical and demographic variables. We assessed QoL, symptom burden, and psychosocial problems using the 12-Item Short-Form Health Survey (SF-12), the Kansas City Cardiomyopathy Questionnaire (KCCQ) and the Edmonton Symptom Assessment System (ESAS). We compared the results of these tools between patients identified as having PC needs (+NECPAL) and patients identified as not having PC needs (-NECPAL). RESULTS: Among the 178 patients, 78 (44%) had PC needs. The prevalence of PC needs was twice as nigh in patients NYHA III/IV as in patients NYHA I/II and almost twice as high in patients older than 70 years as in patients younger than 70 years. Compared to -NECPAL patients, +NECPAL patients had worse QoL, more severe shortness of breath, tiredness, drowsiness, and pain, and more psychosocial problems. CONCLUSION: The prevalence of PC needs in outpatient HF clinics is high and is even higher in older patients and in patients at more advanced NYHA stages. Compared to patients identified as not having PC needs, patients identified as having PC needs have worse QoL, more severe symptoms, and greater psychosocial problems. Including a PC provider in the multidisciplinary team of HF clinics may help to assess and cover these needs.

[Compassionate Cities: Strengthening Social Resources in Communities for Mutual Support at the End of Life]. / Compassionate Cities: Stärkung der sozialen Ressourcen in den Gemeinden für ein gemeinsam getragenes Lebensende.

Compassionate Cities: Strengthening Social Resources in Communities for Mutual Support at the End of Life Abstract. People at the end of life often wish to remain at home for as long as possible. To make this possible to a greater extent, not only health professionals who accompany those affected and their relatives are needed, but also educational programmes to strengthen health literacy at the end of life. Within the framework of the project "Compassionate City Lab of the Bernese People", experiences in dealing with the end of life were collected and published, and a course on advance care planning for elderly people was developed. The project is funded by Health Promotion Switzerland and supported by a partnership between Bernese institutions of higher education, specialised palliative care and primary care, the community, and volunteers in the city of Bern and the Bernese Oberland.

[Telemedicine in Palliative Care: Digital Communication in a Relationship-Based Speciality - Does It Make Sense?] / Telemedizin in der Palliative Care: Digitale Kommunikation in einem beziehungsbasierten Fachgebiet ­ ist das sinnvoll?

Telemedicine in Palliative Care: Digital Communication in a Relationship-Based Speciality - Does It Make Sense? Abstract. Telemedicine in palliative care is established especially in countries with large geographical distances. Digital forms of communication (virtual consultations) are most frequently used and well-accepted by patients and caregivers. The main benefit lies in the reduction of the access barrier in the outpatient setting. Advantages are stress reduction for patients (travel, accessibility) and reduction in the care burden for relatives. Additional benefits compared to the physical visit for symptom-control, quality of life and costs are unclear. Risks are influenced by the lack of physical interaction and data security. To what extent telepalliative care makes sense in a high-density health system is difficult to predict. It is therefore important to use these new tools in a carefully adapted and scientifically verified way.

[Communicating Prognosis and Expectations in Advanced Disease - A Balancing Act in Practice]. / Kommunikation von Prognose und Erwartungen bei fortgeschrittenen Erkrankungen ­ eine Gratwanderung in der Praxis.

Communicating Prognosis and Expectations in Advanced Disease - A Balancing Act in Practice Abstract. To prepare the end of life, to plan important things, to spend the remaining time of life not only with medical treatments, but to live - these are frequently expressed wishes of people with progressive diseases. Prognostic statements are feared by professionals. At the same time, when talking about what lies ahead for those affected, professionals very often make over-optimistic promises. A broader definition of the term prognosis as well as a careful handling of expectations can help to define realistic goals together.

Validation of the German version of the needs assessment tool: progressive disease-heart failure.

BACKGROUND: The Needs Assessment Tool: Progressive Disease-Heart Failure (NAT: PD-HF) is a tool created to assess the needs of people living with heart failure and their informal caregivers to assist delivering care in a more comprehensive way that addresses actual needs that are unmet, and to improve quality of life. In this study, we aimed to (1) Translate the tool into German and culturally adapt it. (2) Assess internal consistency, inter-rater reliability, and test-retest reliability of the German NAT: PD-HF. (3) Evaluate whether and how patients and health care personnel understand the tool and its utility. (4) Assess the tool's face validity, applicability, relevance, and acceptability among health care personnel. METHODS: Single-center validation study. The tool was translated from English into German using a forward-backward translation. To assess internal consistency, we used Cronbach´s alpha. To assess inter-rater reliability and test-retest reliability, we used Cohen´s kappa, and to assess validity we used face validity. RESULTS: The translated tool showed good internal consistency. Raters were in substantial agreement on a majority of the questions, and agreement was almost perfect for all the questions in the test-retest analysis. Face validity was rated high by health care personnel. CONCLUSION: The German NAT: PD-HF is a reliable, valid, and internally consistent tool that is well accepted by both patients and health care personnel. However, it is important to keep in mind that effective use of the tool requires training of health care personnel.

Single early palliative care intervention added to usual oncology care for patients with advanced cancer: A randomized controlled trial (SENS Trial).

BACKGROUND: International oncology societies recommend early palliative care. Specific models to integrate early palliative care efficiently into clinical practice are debated. The authors designed a study to look at the quantitative and qualitative outcomes of an early palliative care intervention in oncological care to decrease stress and improve quality of life. AIMS: To compare a single structured early palliative care intervention added to a usual oncology care in terms of distress and health-related quality of life at baseline compared to 6 months after enrollment. DESIGN: This multicenter randomized controlled trial (NCT01983956) enrolled adult patients with advanced cancer. Participants were either randomly assigned to usual oncology care alone or usual care plus a structured early palliative care intervention. SETTING/PARTICIPANTS: One hundred fifty adult patients with a variety of advanced cancer diagnoses were randomized. Seventy-four participants were in the intervention and 76 participants in the control group. The primary outcome was the change in patient distress assessed by the National Comprehensive Cancer Network distress thermometer at 6 months. Health-related quality of life, the secondary outcome, was assessed by the Functional Assessment of Cancer Therapy-General Questionnaire. RESULTS: The results showed no significant effect of the early palliative care intervention neither on patient distress nor on health-related quality of life. CONCLUSION: The addition of an early intervention to usual care for patients with advanced cancer did not improve distress or quality of life. Thus, patients may need more intensive early palliative care with continuous professional support to identify and address their palliative needs early.

Early palliative care integration trial: consultation content and interaction dynamics.

OBJECTIVES: Evidence for the positive impact of the early integration of palliative care (EPC) continues to grow. Less is known about how EPC improves patient and family outcomes, including the content of EPC consultations. Therefore, we aimed to better understand the content of EPC consultations including areas addressed, percentage covered per area and interaction style. METHODS: As part of a trial in which EPC in addition to oncology care was compared with oncology care alone, we audio recorded 10 interventions. The palliative care team led the interventions using SENS, a conversation structure, which stands for: Symptoms, End-of-life decision-making, Network and Support. We employed two approaches to analysis: the Roter interaction analysis system (RIAS) to analyse interaction dynamics and SENS as a framework for content analysis. RESULTS: Physician-patient communication covered 91% of the interaction. According to RIAS, the consultations were evenly dominated between physicians and patients (ratio=1.04) and highly patient-centred (ratio=1.26). Content wise, rapport was the largest category covering 27% of the consultation, followed by decision-making (21%) and by symptom assessment/management (17%) including 8.1% for physical symptoms and 5.4% for psychosocial aspects. Network discussions covered 17%, and lastly, support for the family 7%. CONCLUSIONS: EPC consultations cover a variety of end-of-life topics while putting a high value in establishing rapport, developing a relationship with patients, and on providing reassurance and positive emotional talk. EPC consultations using predefined structures may guarantee that a minimum of important aspects are addressed in a way in which the relationship with the patient remains at the centre.

Impact of home-based palliative care on health care costs and hospital use: A systematic review.

OBJECTIVE: To assess the effectiveness of home-based palliative care (HBPC) on reducing hospital visits and whether HBPC lowered health care cost. METHOD: We searched six bibliographic databases (Embase (Ovid); Cochrane Central Register of Controlled Trials; Medline (Ovid); PubMed; Web of Science Core Collection; and, CINAHL) until February 2019 and performed a narrative synthesis of our findings. RESULTS: Of the 1,426 identified references, 21 articles based on 19 unique studies met our inclusion criteria, which involved 92,000 participants. In both oncological and non-oncological patients, HBPC consistently reduced the number of hospital visits and their length, as well as hospitalization costs and overall health care costs. Even though home-treated patients consumed more outpatient resources, a higher saving in the hospital costs counterbalanced this. The reduction in overall health care costs was most noticeable for study periods closer to death, with greater reductions in the last 2 months, last month, and last two weeks of life. SIGNIFICANCE OF RESULTS: Stakeholders should recognize HBPC as an intervention that decreases patient care costs at end of life and therefore health care providers should assess the preferences of patients nearing the end-of-life to identify those who will benefit most from HBPC.

Development of an international Core Outcome Set (COS) for best care for the dying person: study protocol.

BACKGROUND: In contrast to typical measures employed to assess outcomes in healthcare such as mortality or recovery rates, it is difficult to define which specific outcomes of care are the most important in caring for dying individuals. Despite a variety of tools employed to assess different dimensions of palliative care, there is no consensus on a set of core outcomes to be measured in the last days of life. In order to optimise decision making in clinical practice and comparability of interventional studies, we aim to identify and propose a set of core outcomes for the care of the dying person. METHODS: Following the COMET initiative approach, the proposed study will proceed through four stages to develop a set of core outcomes: In stage 1, a systematic review of the literature will identify outcomes measured in existing peer reviewed literature, as well as outcomes derived through qualitative studies. Grey literature, will also be included. Stage 2 will allow for the identification and determination of patient and proxy defined outcomes of care at the end of life via quantitative and qualitative methods at an international level. In stage 3, from a list of salient outcomes identified through stages 1 and 2, international experts, family members, patients, and patient advocates will be asked to score the importance of the preselected outcomes through a Delphi process. Stage 4 consists of a face-to-face consensus meeting of international experts and patient/family representatives in order to define, endorse, and propose the final Core Outcomes Set. DISCUSSION: Core Outcome Sets aim at promoting uniform assessment of care outcomes in clinical practice as well as research. If consistently employed, a robust set of core outcomes for the end of life, and specifically for the dying phase, defined by relevant stakeholders, can ultimately be translated into best care for the dying person. Patient care will be improved by allowing clinicians to choose effective and meaningful treatments, and research impact will be improved by employing internationally agreed clinically relevant endpoints and enabling accurate comparison between studies in systematic reviews and/or in meta-analyses.

Does Time for (in)Direct Nursing Care Activities at the End of Life for Patients With or Without Specialized Palliative Care in a University Hospital Differ? A Retrospective Analysis.

BACKGROUND: Nurses' end of life (EoL) care focuses on direct (eg, physical) and indirect (e,g, coordination) care. Little is known about how much time nurses actually devote to these activities and if activities change due to support by specialized palliative care (SPC) in hospitalized patients. AIMS: (1) Comparing care time for EoL patients receiving SPC to usual palliative care (UPC);(2) Comparing time spent for direct/indirect care in the SPC group before and after SPC. METHODS: Retrospective observational study; nursing care time for EoL patients based on tacs® data using nonparametric and parametric tests. The Swiss data method tacs measures (in)direct nursing care time for monitoring and cost analyses. RESULTS: Analysis of tacs® data (UPC, n = 642; SPC, n = 104) during hospitalization before death in 2015. Overall, SPC patients had higher tacs® than UPC patients by 40 direct (95% confidence interval [CI]: 5.7-75, P = .023) and 14 indirect tacs® (95% CI: 6.0-23, P < .001). No difference for tacs® by day, as SPC patients were treated for a longer time (mean number of days 7.2 vs 16, P < .001).Subanalysis for SPC patients showed increased direct care time on the day of and after SPC (P < .001), whereas indirect care time increased only on the day of SPC. CONCLUSIONS: This study gives insight into nurses' time for (in)direct care activities with/without SPC before death. The higher (in)direct nursing care time in SPC patients compared to UPC may reflect higher complexity. Consensus-based measurements to monitor nurses' care activities may be helpful for benchmarking or reimbursement analysis.

Which Cost Components Influence the Cost of Palliative Care in the Last Hospitalization? A Retrospective Analysis of Palliative Care Versus Usual Care at a Swiss University Hospital.

CONTEXT: Although the number of studies on the economic impact of palliative care (PC) is growing, the great majority report costs from North America. OBJECTIVES: We aimed to provide a comprehensive overview of PC hospital cost components from the perspective of a European mixed funded health care system by identifying cost drivers of PC and quantifying their effect on hospital costs compared to usual care (UC). METHODS: We performed a retrospective, observational analysis examining cost data from the last hospitalization of patients who died at a large academic hospital in Switzerland comparing patients receiving PC vs. UC. RESULTS: Total hospital costs were similar in PC and UC with a mean difference of CHF -2777 [95% CI -12,713 to 8506, P = 0.60]. Average costs per day decreased by CHF -3224 [95% CI -3811 to -2631, P < 0.001] for PC patients with significant reduction of costs for diagnostic intervention and medication. Higher cost components for PC patients were catering, room, nursing, social counseling, and nonmedical therapists. In sensitivity analyses, when we restricted PC exposure to three days from admission, total costs and average costs per day were significantly lower for PC. CONCLUSION: Studies measuring the impact of PC on hospital costs should analyze various cost components beyond total costs to understand wanted and potentially unwanted cost-reducing effects. An international definition of a set of cost components, specific for cost-impact PC studies, may help avoid superficial and potentially dangerous cost discussions.

Using the Term "Palliative Care": International Survey of How Palliative Care Researchers and Academics Perceive the Term "Palliative Care".

Background: The term "palliative care" (PC) has often been found to have a negative connotation leading some to suggest rebranding and some services to change their name. Perceptions of the PC community about the term remain largely unexplored. Objective: To explore how PC researchers/academics perceive the term is the objective of this study. Design: This is a cross-sectional survey of attendees to the 10th World Research Congress of the EAPC. The questionnaire covered areas of academic activity, including the use of the term. We analyzed data through descriptive and nonparametric statistics and open responses through content analysis. Participants: Academics and researchers in PC were the participants in this study. Results: Of 318 respondents, the majority were women (65%), physicians (48%), and had a postgraduate degree (90%). For 40%, the term hindered the positioning of PC, 28% worried about using the term, and 55% did not discuss these difficulties. We found significant differences between responses and several demographics (e.g., younger age and higher likelihood of worrying about the term). Through open responses, we identified that the term is widely in use, and that its limitations are seen as a cultural by-product, and not as something that a name change would solve. Conclusions: Senior PC academics, researchers, and clinicians have an onus to ensure that colleagues with limited PC experience have the opportunity to discuss and explore the impact of the term on the practice of research. Regarding the term itself, the community's views are conclusive: although using the term will remain a difficult task, the field's identity is in the name.

An early palliative care intervention can be confronting but reassuring: A qualitative study on the experiences of patients with advanced cancer.

BACKGROUND: Intervention trials confirm that patients with advanced cancer receiving early palliative care experience a better quality of life and show improved knowledge about and use of palliative care services. To involve patients in future health-care decisions, health professionals should understand patients' perspectives. However, little is known about how patients' experience such interventions. AIM: To explore advanced cancer patients' experiences with a structured early palliative care intervention, its acceptability and impact on the patients' life including influencing factors. DESIGN: Qualitative content analysis of in-depth, semi-structured interviews. SETTING/PARTICIPANTS: Patients with various advanced cancer diagnoses were enrolled in a multicenter randomized controlled trial (NCT01983956), which investigated the impact of "Symptoms, End-of-life decisions, Network, Support," a structured early palliative care intervention, on distress. Of these, 20 patients who underwent the intervention participated in this study. RESULTS: Participants received the intervention well and gained a better understanding of their personal situation. Patients reported that the intervention can feel "confronting" but with the right timing it can be confirming and facilitate family conversations. Patients' personal background and the intervention timing within their personal disease trajectory influenced their emotional and cognitive experiences; it also impacted their understanding of palliative care and triggered actions toward future care planning. CONCLUSION: Early palliative care interventions like "Symptoms, End-of-life decisions, Network, Support" may provoke emotions and feel "confrontational" often because this is the first time when issues about one's end of life are openly discussed; yet, advanced cancer patients found it beneficial and felt it should be incorporated into routine care.

An online international comparison of thresholds for triggering a negative response to the "Surprise Question": a study protocol.

BACKGROUND: The Surprise Question (SQ) "would I be surprised if this patient were to die in the next 12 months?" has been suggested to help clinicians, and especially General Practitioners (GPs), identify people who might benefit from palliative care. The prognostic accuracy of this approach is unclear and little is known about how GPs use this tool in practice. Are GPs consistent, individually and as a group? Are there international differences in the use of the tool? Does including the alternative Surprise Question ("Would I be surprised if the patient were still alive after 12 months?") alter the response? What is the impact on the treatment plan in response to the SQ? This study aims to address these questions. METHODS: An online study will be completed by 600 (100 per country) registered GPs. They will be asked to review 20 hypothetical patient vignettes. For each vignette they will be asked to provide a response to the following four questions: (1) the SQ [Yes/No]; (2) the alternative SQ [Yes/No]; (3) the percentage probability of dying [0% no chance - 100% certain death]; and (4) the proposed treatment plan [multiple choice]. A "surprise threshold" for each participant will be calculated by comparing the responses to the SQ with the probability estimates of death. We will use linear regression to explore any differences in thresholds between countries and other clinician-related factors, such as years of experience. We will describe the actions taken by the clinicians and explore the differences between groups. We will also investigate the relationship between the alternative SQ and the other responses. Participants will receive a certificate of completion and the option to receive feedback on their performance. DISCUSSION: This study explores the extent to which the SQ is consistently used at an individual, group, and national level. The findings of this study will help to understand the clinical value of using the SQ in routine practice. TRIAL REGISTRATION: Clinicaltrials.gov NCT03697213 (05/10/2018). Prospectively registered.
