Establishing a Core Outcome Set for Autosomal Dominant Polycystic Kidney Disease: Report of the Standardized Outcomes in Nephrology–Polycystic Kidney Disease (SONG-PKD) Consensus Workshop

The omission of outcomes that are of relevance to patients, clinicians, and regulators across trials in autosomal dominant polycystic kidney disease (ADPKD) limits shared decision making. The Standardized Outcomes in Nephrology-Polycystic Kidney Disease (SONG-PKD) Initiative convened an international consensus workshop on October 25, 2018, to discuss the identification and implementation of a potential core outcome set for all ADPKD trials. This article summarizes the discussion from the workshops and the SONG-PKD core outcome set. Key stakeholders including 11 patients/caregivers and 47 health professionals (nephrologists, policy makers, industry, and researchers) attended the workshop. Four themes emerged: "Relevance of trajectory and impact of kidney function" included concerns about a patient's prognosis and uncertainty of when they may need to commence kidney replacement therapy and the lack of an early prognostic marker to inform long-term decisions; "Discerning and defining pain specific to ADPKD" highlighted the challenges in determining the origin of pain, adapting to the chronicity and repeated episodes of pain, the need to place emphasis on pain management, and to have a validated measure for pain; "Highlighting ADPKD consequences" encompassed cyst-related complications and reflected patient's knowledge because of family history and the hereditary nature of ADPKD; and "Risk for life-threatening but rare consequences" such as cerebral aneurysm meant considering both frequency and severity of the outcome. Kidney function, mortality, cardiovascular disease, and pain were established as the core outcomes for ADPKD.

Establishing Core Cardiovascular Outcome Measures for Trials in Hemodialysis: Report of an International Consensus Workshop

Cardiovascular disease (CVD) affects more than two-thirds of patients receiving hemodialysis and is the leading cause of death in this population, yet CVD outcomes are infrequently and inconsistently reported in trials in patients receiving hemodialysis. As part of the Standardised Outcomes in Nephrology-Haemodialysis (SONG-HD) initiative, we convened a consensus workshop to discuss the potential use of myocardial infarction and sudden cardiac death as core outcome measures for CVD for use in all trials in people receiving hemodialysis. Eight patients or caregivers and 46 health professionals from 15 countries discussed selection and implementation of the proposed core outcome measures. Five main themes were identified: capturing specific relevance to the hemodialysis population (acknowledging prevalence, risk, severity, unique symptomology, and pathophysiology), the dilemmas in using composite outcomes, addressing challenges in outcome definitions (establishing a common definition and addressing uncertainty in the utility of biomarkers in hemodialysis), selecting a meaningful metric for decision making (to facilitate comparison across trials), and enabling and incentivizing implementation (by ensuring that cardiologists are involved in the development and integration of the outcome measure into registries, trial design, and reporting guidelines). Based on these themes, participants supported the use of myocardial infarction and sudden cardiac death as core outcome measures of CVD to be reported in all hemodialysis trials.

Clinical and public health implications of periodontal and systemic diseases: An overview.

Severe periodontitis is defined by extensive loss of the tooth attachment apparatus. It is the sixth most common human disease and is estimated to affect 11.2% of the global adult population, hence representing a significant healthcare, social, and economic burden. Since the 1990s, multiple epidemiologic, experimental, and interventional studies have evidenced how periodontitis may also impact systemic health and it has been independently associated with the majority of chronic noncommunicable diseases. The evidence supporting these associations, mainly focusing on diabetes, pregnancy complications, and cardiovascular disease, was thoroughly reviewed in 2012 by an international consensus workshop. In the last 5 years, however, important advances have been made, not only in our understanding of the etiopathogenesis of periodontitis, or concerning the mounting evidence regarding the independent associations between periodontitis, diabetes, and cardiovascular disease, but also with many other systemic diseases including metabolic disease and obesity, rheumatoid arthritis, certain cancers, respiratory diseases, and cognitive disorders including Alzheimer's disease. This review describes these scientific advances by gathering together the existing evidence on the importance and relevance of the associations between periodontitis and many systemic diseases.

Which outcome domains are important in palliative care and when? An international expert consensus workshop, using the nominal group technique

Background: When capturing patient-level outcomes in palliative care, it is essential to identify which outcome domains are most important and focus efforts to capture these, in order to improve quality of care and minimise collection burden. Aim: To determine which domains of palliative care are most important for measurement of outcomes, and the optimal time period over which these should be measured. Design: An international expert consensus workshop using nominal group technique. Data were analysed descriptively, and weighted according to ranking (1–5, lowest to highest priority) of domains. Participants’ rationales for their choices were analysed thematically. Setting/participants: In all, 33 clinicians and researchers working globally in palliative care outcome measurement participated. Two groups (n = 16; n = 17) answered one question each (either on domains or optimal timing). This workshop was conducted at the 9th World Research Congress of the European Association for Palliative Care in 2016. Results: Participants’ years of experience in palliative care and in outcome measurement ranged from 10.9 to 14.7 years and 5.8 to 6.4 years, respectively. The mean scores (weighted by rank) for the top-ranked domains were ‘overall wellbeing/quality of life’ (2.75), ‘pain’ (2.06), and ‘information needs/preferences’ (2.06), respectively. The palliative measure ‘Phase of Illness’ was recommended as the preferred measure of time period over which the domains were measured. Conclusion: The domains of ‘overall wellbeing/quality of life’, ‘pain’, and ‘information needs/preferences’ are recommended for regular measurement, assessed using ‘Phase of Illness’. International adoption of these recommendations will help standardise approaches to improving the quality of palliative care.

Research Priorities for Endometriosis.

The 3rd International Consensus Workshop on Research Priorities in Endometriosis was held in São Paulo on May 4, 2014, following the 12th World Congress on Endometriosis. The workshop was attended by 60 participants from 19 countries and was divided into 5 main sessions covering pathogenesis/pathophysiology, symptoms, diagnosis/classification/prognosis, disease/symptom management, and research policy. This research priorities consensus statement builds on earlier efforts to develop research directions for endometriosis. Of the 56 research recommendations from the 2011 meeting in Montpellier, a total of 41 remained unchanged, 13 were updated, and 2 were deemed to be completed. Fifty-three new research recommendations were made at the 2014 meeting in Sao Paulo, which in addition to the 13 updated recommendations resulted in a total of 66 new recommendations for research. The research recommendations published herein, as well as those from the 2 previous papers from international consensus workshops, are an attempt to promote high-quality research in endometriosis by identifying and agreeing on key issues that require investigation. New areas included in the 2014 recommendations include infertility, patient stratification, and research in emerging nations, in addition to an increased focus on translational research. A revised and updated set of research priorities that builds on this document will be developed at the 13th World Congress on Endometriosis to be held on May 17-20, 2017, in Vancouver, British Columbia, Canada.

Establishing Core Outcome Domains in Hemodialysis: Report of the Standardized Outcomes in Nephrology–Hemodialysis (SONG-HD) Consensus Workshop

Evidence-informed decision making in clinical care and policy in nephrology is undermined by trials that selectively report a large number of heterogeneous outcomes, many of which are not patient centered. The Standardized Outcomes in Nephrology-Hemodialysis (SONG-HD) Initiative convened an international consensus workshop on November 7, 2015, to discuss the identification and implementation of a potential core outcome set for all trials in hemodialysis. The purpose of this article is to report qualitative analyses of the workshop discussions, describing the key aspects to consider when establishing core outcomes in trials involving patients on hemodialysis therapy. Key stakeholders including 8 patients/caregivers and 47 health professionals (nephrologists, policymakers, industry, and researchers) attended the workshop. Attendees suggested that identifying core outcomes required equitable stakeholder engagement to ensure relevance across patient populations, flexibility to consider evolving priorities over time, deconstruction of language and meaning for conceptual consistency and clarity, understanding of potential overlap and associations between outcomes, and an assessment of applicability to the range of interventions in hemodialysis. For implementation, they proposed that core outcomes must have simple, inexpensive, and validated outcome measures that could be used in clinical care (quality indicators) and trials (including pragmatic trials) and endorsement by regulatory agencies. Integrating these recommendations may foster acceptance and optimize the uptake and translation of core outcomes in hemodialysis, leading to more informative research, for better treatment and improved patient outcomes.

Halitosis management by the general dental practitioner—results of an international consensus workshop**Workshop at BREATH ANALYSIS Summit 2013—International Conference of Breath Research, 9th of June 2013—Saarbrücken/Wallerfangen, Germany.

Clinical investigations on patients suffering from halitosis clearly reveal that in the vast majority of cases the source for an offensive breath odor can be found within the oral cavity (90%). Based on these studies, the main sources for intra-oral halitosis where tongue coating, gingivitis/periodontitis or a combination of the two. Thus, it is perfectly logical that general dental practitioners (GDPs) should be able to manage intra-oral halitosis under the conditions found in a normal dental practice. However, GDPs who are interested in diagnosing and treating halitosis are challenged to incorporate scientifically based strategies for use in their clinics. Therefore, the present paper summarizes the results of a consensus workshop of international authorities held with the aim to reach a consensus on general guidelines on how to assess and diagnose patients’ breath odor concerns and general guidelines on regimens for the treatment of halitosis.

The Selection and Use of Outcome Measures in Palliative and End-of-Life Care Research: The MORECare International Consensus Workshop

ContextA major barrier to widening and sustaining palliative care service provision is the requirement for better selection and use of outcome measures. Service commissioning is increasingly based on patient, carer, and service outcomes as opposed to service activity. ObjectivesTo generate recommendations and consensus for research in palliative and end-of-life care on the properties of the best outcome measures, enhancing the validity of proxy-reported data and optimal data collection time points. MethodsAn international expert “workshop” was convened and an online consensus survey was undertaken using the MORECare Transparent Expert Consultation to generate recommendations and level of agreement. We focused on three areas: 1) measurement properties, 2) use of proxies, and 3) measurement timing. Data analysis comprised descriptive analysis of aggregate scores and collation of narrative comments. ResultsThere were 31 workshop attendees; 29 recommendations were included in the online survey, completed by 28 experts. The top three recommendations by area were the following: 1) the properties of the best outcome measures are responsive to change over time and capture clinically important data, 2) to enhance the validity of proxy data requires clear and specific guidelines to aid lay individuals' and/or professionals' completion of proxy measures, and 3) data collection time points need clear identification to establish a baseline. ConclusionOutcome measurement in palliative and end-of-life care requires the use of psychometrically robust measures that are clinically responsive, with defined data collection time points to establish a baseline and clear administration guidelines to complete proxy measures. To further the field requires clinical imperatives to more closely inform recommendations on outcome measurement.

International Practice Survey on the Management of Brain Metastases: Third International Consensus Workshop on Palliative Radiotherapy and Symptom Control

AimTo evaluate international patterns of practice for the management of metastatic disease to the brain. Materials and methodsAn online international practice survey was conducted from April to June 2010. Most of the survey questions were based on common management issues for which optimal management using level 1 evidence was lacking. The survey consisted of three sections: respondent demographics, 13 general questions regarding surgery, whole brain radiotherapy (WBRT) and radiosurgery and 13 questions related to specific scenarios. ResultsIn total, 445 individuals responded to the survey over a 3 month period. Ninety per cent of respondents worked in a hospital-based setting. Ninety-three per cent of respondents were radiation oncologists. Thirty-seven per cent worked in an academic setting. Only three of 26 survey questions generated at least 70% agreement for a favoured response. Eighty-eight per cent of respondents chose comfort measures only for patients with multiple brain metastases who have been previously treated with WBRT and who now present 6 months later with two to four brain metastases (all less than 4 cm in size) with uncontrolled extracranial disease and bedridden state. Seventy-eight per cent of respondents would use WBRT alone for initial treatment in patients with two to four brain metastases (all less than 4 cm in size), with active, uncontrolled extracranial disease and a Karnofsky performance status of 70. Seventy-eight per cent of respondents chose surgical resection for an enlarging single brain metastasis that has been previously treated with radiosurgery. The enlarging single brain metastasis is in a surgically accessible site and is now symptomatic. The patient has controlled extracranial disease, good performance status and magnetic resonance spectroscopy was not diagnostic. ConclusionsThere is a lack of uniform agreement for many common management issues (not well answered by level 1 evidence) in patients with metastatic disease to the brain.

International Practice Survey on Palliative Lung Radiotherapy: Third International Consensus Workshop on Palliative Radiotherapy and Symptom Control

BackgroundThe purpose of this work was to disseminate international practice survey results created in conjunction with the Third International Lung Cancer Consensus Workshop. Patients and MethodsIn conjunction with the American Society for Radiation Oncology (ASTRO) Guideline for Palliative Lung Cancer Care and International Workshop Consensus statements, an online international practice survey was conducted during the summer of 2010. The survey included demographic, educational, and clinical questions as well as 5 cases exploring the role of external beam radiotherapy, endobronchial brachytherapy, and concurrent chemoradiation. ResultsA total of 279 individuals responded to the survey over a 3-month period. Most respondents were hospital-based, academic, or government-funded radiation oncologists. Factors that consistently related to use and choice of external beam dose fractionation included estimated treatment benefit to patient, performance status (PS), symptom severity, patient choice, estimated prognosis, and previous radiation to the same site. Factors consistently not related to use and dose fractionation included requirement for future radiation therapy, department policy, and waiting lists. A significant range of dose fractionation schedules existed for external beam (n = 35) and endobronchial brachytherapy treatment (n = 10). The integration of concurrent chemotherapy was recorded by a significant minority of respondents despite lack of level I evidence to support its use. Geographic differences in the use of external beam dose fractionation and of concurrent chemotherapy were seen. ConclusionsVarious patient, tumor, treatment, and logistic factors are associated with the variable use and external beam dose fractionation of palliative lung treatments. The copublication of the ASTRO Guideline for Palliative Lung Cancer Care and International Workshop Consensus statements should assist clinicians by providing evidence-based care.

International Neuropathy Workshop of 2009: Introduction to the final reports

Neuropathies are amongst the most common of the long-term complications of diabetes, affecting up to 50% of patients. Their clinical features vary immensely and patients may present with a wide spectrum of specialties, from neurology to urology, for example, or from cardiology to podiatry. Neuropathies are typically characterized by a progressive loss of nerve fibres which may affect both of the principal divisions of the peripheral nervous system. The epidemiology and natural history of the diabetic neuropathies remain poorly defined. The International Consensus Workshop in Toronto in 2009 arose from the fact that at the moment there are no clear, universally accepted guidelines regarding the definition of diabetic neuropathies. This has resulted in a massive variation in how neuropathy is diagnosed in different centres and countries. A preliminary summary report of the Toronto meeting was published in 2010. The series of papers published in this issue of Diabetes/Metabolism Research and Reviews are the detailed reports that came from each sub-group of this Consensus panel. These reviews cover the problems with definitions and classification of neuropathy, the management of painful neuropathy and then the sub-group of small fibre neuropathies. There are also 3 papers on the autonomic neuropathies, covering cardiovascular autonomic neuropathies, as well as other areas of the autonomic neuropathies including gastrointestinal, urogenital and pseudomotor neuropathies. This series of papers will give the reader detailed information on the diverse aspects of diabetic neuropathies, their measurement and management, and will also assist in the selection of appropriate measures of both autonomic and somatic nerve function in clinical trials. This is clearly work in progress as diagnostic criteria for diabetic neuropathies are likely to evolve with developments in the field.

Recommendations from the International Consensus Workshop: convergence on an orofacial pain taxonomy

This 2·5-day workshop was organized by the International RDC/TMD Consortium Network of the International Association for Dental Research and the Orofacial Pain Special Interest Group of the International Association for the Study of Pain. Workshop participation was by invitation based on representation within the field, which included the Consortium Network, the Orofacial Pain Special Interest Group, the National Institute for Dental and Craniofacial Research, American Academy of Orofacial Pain, the European Academy of Craniomandibular Disorders, and the International Headache Society; other disciplines included radiology, psychology, ontology, and patient advocacy. The workshop members were divided into workgroups that reviewed core literature describing the properties of the RDC/TMD, provided recommendations for revision, and suggested relevant research directions. The goals of this workshop were to (i) finalize the revision of the RDC/TMD into a Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), which would be more appropriate for routine clinical implementation, (ii) provide a broad foundation for the further development of suitable diagnostic systems for not only TMD but also oro-facial pain as well, and (iii) provide research recommendations oriented towards improving our understanding of TMD and oro-facial pain. This report provides the full description of the workshop and Executive Summary, and it acknowledges the participants and sponsors.

Priorities for Endometriosis Research: Recommendations From an International Consensus Workshop

Endometriosis is an estrogen-dependent disorder where endometrial tissue forms lesions outside the uterus. Endometriosis affects an estimated 10% of women in the reproductive-age group, rising to 30% to 50% in patients with infertility and/or pain, with significant impact on their physical, mental, and social well-being. There is no known cure, and most current medical treatments are not suitable long term due to their side-effect profiles. Endometriosis has an estimated annual cost in the United States of $18.8 to $22 billion (2002 figures). Although endometriosis was first described more than 100 years ago, current knowledge of its pathogenesis, spontaneous evolution, and the pathophysiology of the related infertility and pelvic pain, remain unclear. A consensus workshop was convened following the 10th World Congress on Endometriosis to establish recommendations for priorities in endometriosis research. One major issue identified as impacting on the capacity to undertake endometriosis research is the need for multidisciplinary expertise. A total of 25 recommendations for research have been developed, grouped under 5 subheadings: (1) diagnosis, (2) classification and prognosis, (3) treatment and outcome, (4) epidemiology, and (5) pathophysiology. Endometriosis research is underfunded relative to other diseases with high health care burdens. This may be due to the practical difficulties of developing competitive research proposals on a complex and poorly understood disease, which affects only women. By producing this consensus international research priorities statement it is the hope of the workshop participants that researchers will be encouraged to develop new interdisciplinary research proposals that will attract increased funding support for work on endometriosis.

Achieving benefit for patients in primary care informatics: the report of a international consensus workshop at Medinfo 2007

Landmark reports suggest that sharing health data between clinical computer systems should improve patient safety and the quality of care. Enhancing the use of informatics in primary care is usually a key part of these strategies. To synthesise the learning from the international use of informatics in primary care. The workshop was attended by 21 delegates drawn from all continents. There were presentations from USA, UK and the Netherlands, and informal updates from Australia, Argentina, and Sweden and the Nordic countries. These presentations were discussed in a workshop setting to identify common issues. Key principles were synthesised through a post-workshop analysis and then sorted into themes. Themes emerged about the deployment of informatics which can be applied at health service, practice and individual clinical consultation level: 1 At the health service or provider level, success appeared proportional to the extent of collaboration between a broad range of stakeholders and identification of leaders. 2 Within the practice much is currently being achieved with legacy computer systems and apparently outdated coding systems. This includes prescribing safety alerts, clinical audit and promoting computer data recording and quality. 3 In the consultation the computer is a 'big player' and may make traditional models of the consultation redundant. We should make more efforts to share learning; develop clear internationally acceptable definitions; highlight gaps between pockets of excellence and real-world practice, and most importantly suggest how they might be bridged. Knowledge synthesis from different health systems may provide a greater understanding of how the third actor (the computer) is best used in primary care.

Microvascular Tumor Invasion, Tumor Size and Fuhrman Grade: A Pathological Triad for Prognostic Evaluation of Renal Cell Carcinoma

The biological behavior and clinical outcome of renal cell carcinoma are difficult to predict. We investigated the prognostic impact of clinicopathological variables to establish a risk stratification model to predict recurrence and survival rates. We studied 230 patients with renal cell carcinoma (stages T(1-4) N(x) M(0)) who underwent radical nephrectomy and/or nephron sparing surgery, and were followed for a median of 48 months (range 3 to 140). Univariate and multivariate analyses were performed, and the influence of clinical presentation, histological tumor size, tumor grade, lymph node involvement and microvascular tumor invasion on disease-free and cancer specific survival curves was determined. A composition model based on independent prognostic variables was then created to stratify tumors into low, intermediate and high risk of progression. The tumor recurrence rate was 17% (39 of 230) and the cancer specific mortality rate was 13% (31 of 230). Multivariate analyses determined that microvascular tumor invasion, tumor grade and tumor size were the only independent prognostic factors. Disease-free survival rates for low, intermediate and high risk tumors were 94.7%, 56.8% and 13.1%, respectively. Cancer specific survival rates were 94.7%, 61.7% and 32.0%, respectively. Tumor size, Fuhrman grade and microvascular tumor invasion are strong and independent predictors of survival of patients with renal cell carcinoma. Risk assessment and stratification based on this triad of pathological features may allow better individualization of followup schedules and trials of adjuvant treatment for patients with renal cell carcinoma.

Reducing Health Disparity in People with Intellectual Disabilities: A Report from Health Issues Special Interest Research Group of the International Association for the Scientific Study of Intellectual Disabilities1

Abstract Disparities in the health status and care experienced by people with intellectual disabilities are increasingly being recognized. This special report presents the results of an international expert consensus workshop held under the auspices of the Health Issues Special Interest Research Group of the International Association for the Scientific Study of Intellectual Disabilities. The workshop's presentations were designed to identify domains of health disparity and identify examples of evidence‐based or good practice and from them define statements and recommendations that would form the basis of an agenda for change. The report recognizes the breadth of domains that impact on disparity in health among people with intellectual disabilities by highlighting the importance of classification and the direct recognition of the increased morbidity and reduced life expectancy that these people experience. The report also considers population‐based causes of disparity relating to social circumstances and inequalities in the provision of health and social services. Individual predispositions attributable to sex or genetic factors and potential solutions actualized through self‐determination are discussed.

Evolving Consensus in Portal Hypertension Report of the Baveno IV Consensus Workshop on methodology of diagnosis and therapy in portal hypertension

Portal hypertension is associated with the most severe complications of cirrhosis, including ascites, hepatic encephalopathy, and bleeding from gastro-esophageal varices. Despite the progress achieved over the last decades, the 6-week mortality associated with variceal bleeding is still in the order of 10–20%. Awareness of the difficulty inherent to the evaluation of diagnostic tools and the design and conduct of good clinical trials for the treatment of portalhypertensionhas led to theorganization, since1986,of a series of consensus meetings. The first one was organized by Andrew Burroughs in Groningen, The Netherlands [1]. After Groningen, other meetings followed, in Baveno in 1990 (Baveno I) [2] and in 1995 (Baveno II) [3,4], in Milan in 1992 [5], in Reston, USA, in 1996 [6], in Stresa in 2000 (Baveno III) [7,8], again in Baveno in 2005 (Baveno IV) [9,10], and in Atlanta in 2007 [11]. The aims of these meetings were to develop definitions of key events in portal hypertension and variceal bleeding, to review the existing evidence on the natural history, the diagnosis and the therapeutic modalities of portal hypertension, and to issue evidence-based recommendations for the conduct of clinical trials and the management of patients. All these meetings were successful and produced consensus statements on some important points, although some issues remained unsettled. To continue the work of the previous meetings, a Baveno V workshop was held on May 21–22, 2010. The workshop was attended by many of the experts responsible for most of the major achievements of the last years in this field. Many of them had attended the previous meetings as well. The main fields of discussion of the Baveno V workshop were the same as in Baveno I–IV, i.e. the definitions of key events concerning the bleeding episode and the therapeutic options in patients with portal hypertension. For each of these topics, a series of consensus statements were discussed and agreed upon. As in Baveno IV, whenever applicable, the level of existing evidence was evaluated and the recommendations were ranked according to the Oxford System [12] (i.e.: level of evidence from 1 = highest

Updating Consensus in Portal Hypertension: Report of the Baveno III Consensus Workshop on definitions, methodology and therapeutic strategies in portal hypertension

Portal hypertension is the hemodynamic abnormality associated with the most severe complications of cirrhosis, including ascites, hepatic encephalopathy and bleeding from gastroesophageal varices. Since variceal bleeding is a medical emergency associated with significant morbidity and mortality, the evaluation of diagnostic tools and the design and conduct of good clinical trials for the treatment of this condition have always been difficult. Awareness of these difficulties has led to the organization of a series of meetings aimed at reaching consensus on the definitions of some key events related to portal hypertension and variceal bleeding, and at producing guidelines for the conduct of trials in this field. Such meetings took place in Groningen, the Netherlands in 1986 ( 1. Burroughs AK Methodology and Review of Clinical Trials in Portal Hypertension.
