Project description:ObjectiveIt has been suggested that the sequelae of trauma are under-recognized in youth on the autism spectrum. We aimed to generate expert consensus regarding important trauma indicators, including but not limited to traumatic stress symptoms, in autistic youth.MethodsWe recruited 72 experts in autism and/or childhood trauma. Via a 2-round Delphi survey, experts commented on and rated the importance of 48 potential indicators, drawn from PTSD criteria and a broader literature on traumatic sequelae in autism. A revised list of 51 indicators, 18 clinical guidelines developed from expert comments, and summaries of expert qualifications and ratings from Round 1 were submitted to a second round (n = 66; 92% retention) of expert review and rating.ResultsTwenty-two indicators reached consensus (>75% round 2 endorsement). Many, but not all, reflected PTSD criteria, including intrusions (e.g., trauma re-enactments in perseverative play/speech), avoidance of trauma-reminders, and negative alterations in mood/cognition (e.g., diminished interest in activities) and in arousal/reactivity (e.g., exaggerated startle). Experts also identified increased reliance on others, adaptive and language regressions, self-injurious behavior, and non-suicidal self-injury as important indicators. Consensus guidelines emphasized the need for tailored measures, developmentally informed criteria, and multiple informants to increase diagnostic accuracy.ConclusionsExpert consensus emphasizes and informs a need for tailored diagnostic guidelines and measures to more sensitively assess traumatic reactions in autistic youth.

Project description:PurposeNumerous clinical practice guidelines and consensus statements have been published in hernia surgery, however, there is still a need for high-quality evidence to address remaining unanswered questions. The aim of this study was to conduct research priority setting through a modified Delphi process to identify a list of top research priorities in hernia surgery.MethodsA structured literature review of clinical practice guidelines was performed by the steering committee. Topics considered clinically significant, practical to study and lacking strong evidence were extracted and refined into a comprehensive list, then entered into a two-round Delphi survey for prioritization at the Abdominal Core Health Quality Collaborative (ACHQC) Quality Improvement Summit. In round 1, participants were instructed to select any topic that should be prioritized for future research. Topics were ranked according to the proportion of votes and the 25 highest-ranking topics were included in the second round. In round 2, participants were instructed to select only the top 10 topics for research prioritization.ResultsEleven clinical practice guidelines were reviewed. Eighty-seven topics were extracted by the steering committee and submitted for prioritization. After the first round, 25 of the highest-ranking topics were determined and included in the second round. A final list of 11 research questions was identified. The hernia types with the most research interest were inguinal and epigastric/umbilical hernias. Other topics of high interest were the management of diastasis recti, primary versus mesh repairs and expectant management versus surgical repair.ConclusionOur study provides a research agenda generated through expert consensus that may be used in the prioritization of the design and funding of clinical trials in hernia surgery.

Project description:PurposeThe paper investigates whether we can build consensus on wellness domains and create a more universal conceptual framework for wellness.DesignA modified ranking type of Delphi method.ParticipantsTwo separate panels consisting of 23 Finnish and 11 international experts.MethodsPanels were asked to rate the importance of 61 systematic review-based wellness domains and to eventually form a wellness model in both panels. The similarities between the resulting models were investigated and a new conceptual framework for wellness was created.ResultsThe Finnish model included 8 themes and 20 domains, and the international model 5 themes and eleven domains. Eight of the eleven domains were an exact match for the Finnish model (namely mental health, cognitive health, exercise, nutrition, community, life satisfaction, meaningfulness, work-life balance). There were also 2 similar domains that could be found in both models (namely self-care and lifestyle habits, social networks). A new conceptual framework for wellness was created based on these ten domains.ConclusionThe lack of consensus on the wellness construct has made it difficult to find comparable measures that could assess and improve the level of wellness of individuals, organizations, and society. This study offers a conceptual framework that can be further validated and turned into a more universal measurement instrument.

Project description:IntroductionThe ability to perform optimally under pressure is critical across many occupations, including the military, first responders, and competitive sport. Despite recognition that such performance depends on a range of cognitive factors, how common these factors are across performance domains remains unclear. The current study sought to integrate existing knowledge in the performance field in the form of a transdisciplinary expert consensus on the cognitive mechanisms that underlie performance under pressure.MethodsInternational experts were recruited from four performance domains [(i) Defense; (ii) Competitive Sport; (iii) Civilian High-stakes; and (iv) Performance Neuroscience]. Experts rated constructs from the Research Domain Criteria (RDoC) framework (and several expert-suggested constructs) across successive rounds, until all constructs reached consensus for inclusion or were eliminated. Finally, included constructs were ranked for their relative importance.ResultsSixty-eight experts completed the first Delphi round, with 94% of experts retained by the end of the Delphi process. The following 10 constructs reached consensus across all four panels (in order of overall ranking): (1) Attention; (2) Cognitive Control-Performance Monitoring; (3) Arousal and Regulatory Systems-Arousal; (4) Cognitive Control-Goal Selection, Updating, Representation, and Maintenance; (5) Cognitive Control-Response Selection and Inhibition/Suppression; (6) Working memory-Flexible Updating; (7) Working memory-Active Maintenance; (8) Perception and Understanding of Self-Self-knowledge; (9) Working memory-Interference Control, and (10) Expert-suggested-Shifting.DiscussionOur results identify a set of transdisciplinary neuroscience-informed constructs, validated through expert consensus. This expert consensus is critical to standardizing cognitive assessment and informing mechanism-targeted interventions in the broader field of human performance optimization.

Project description:Background and aimsConsensus regarding an optimal algorithm for endoscopic treatment of papillary adenomas has not been established. We aimed to assess the existing degree of consensus among international experts and develop further concordance by means of a Delphi process.MethodsFifty-two international experts in the field of endoscopic papillectomy were invited to participate. Data were collected between August and December 2019 using an online survey platform. Three rounds were conducted. Consensus was defined as ≥70% agreement.ResultsSixteen experts (31%) completed the full process, and consensus was achieved on 47 of the final 79 statements (59%). Diagnostic workup should include at least an upper endoscopy using a duodenoscope (100%) and biopsy sampling (94%). There should be selected use of additional abdominal imaging (75%-81%). Patients with (suspected) papillary malignancy or over 1 cm intraductal extension should be referred for surgical resection (76%). To prevent pancreatitis, rectal nonsteroidal anti-inflammatory drugs should be administered before resection (82%) and a pancreatic stent should be placed (100%). A biliary stent is indicated in case of ongoing bleeding from the papillary region (76%) or concerns for a (micro)perforation after resection (88%). Follow-up should be started 3 to 6 months after initial papillectomy and repeated every 6 to 12 months for at least 5 years (75%).ConclusionsThis is the first step in developing an international consensus-based algorithm for endoscopic management of papillary adenomas. Surprisingly, in many areas consensus could not be achieved. These aspects should be the focus of future studies.

Project description:BackgroundCurrent research evidence challenges clinical decision-making when acupuncture is taken into consideration in the treatment of cognitive impairment (CI). Aiming to provide some viable recommendations for acupuncture practitioners in dealing with actual clinic issues, an expert consensus study was conducted.MethodsA clinical question investigation among 47 acupuncturists yielded 24 initial items. Subsequently, systematic reviews on acupuncture for CI were searched within three online databases. A panel of 30 authoritative experts were requested to respond with agreement, neutrality, or disagreement for each item. Consensus establishment was defined as the percentage of agreement on a given item >80%.ResultsFollowing a 2-round Delphi survey, there were 21 items reaching consensus and three items resulting in no consensus; of which 10 items reached 90∼100% agreement, and 80∼90% expert agreement was achieved for 11 items. These items could be roughly categorized into six domains: (1) therapeutic effects of acupuncture, (2) therapeutic principles, (3) acupoint selection and combination, (4) acupuncture parameters, (5) considerable combined therapies, and (6) possible adverse events.ConclusionWithout ready-made guidelines, this expert consensus may be conducive to guide acupuncturists in implementing clinical acupuncture practice for CI. Moreover, given the lack of high-quality research evidence and plenty of unresolved clinical issues in this field, it is of necessity to carry out more studies to better clarify the treatment algorithm.

Project description:BackgroundImprovement in medico-social services has increased life expectancy and population ageing in Sub-Saharan Africa (SSA). It was estimated that about 163 million people aged 65 and older will be resident in SSA by 2050. There is inadequate ageing research capacity in SSA which necessitates this study to (a) identify a decade-long ageing research opportunities, challenges, and solutions, and (b) prioritize critical ageing research areas and methodologies relevant to the SSA.MethodsWe designed an e-Delphi protocol following the Reporting Guideline for Priority Setting of Health Research with Stakeholder. The stakeholders will be researchers, practitioners, older adults, and caregivers purposively selected through snowballing quota sampling to complete three rounds of e-Delphi surveys. Round 1 will involve open-ended questions derived from the study objectives. Responses from round 1 will be prepared as a checklist for stakeholders to rate during rounds 2 & 3, using a 9-point scale: low priority (1-3), moderate priority (4-6), and high priority (7-9). The criterion for reaching a consensus will be ≥ 70% of stakeholders rating an item "high priority" and ≤ 15% as "low priority." Quantitative data will be analysed using descriptive statistics, Wilcoxon matched-pairs signed-rank test will be used to assess the stability of stakeholders' responses, and qualitative comments will be analysed using content analysis.Discussion and implicationsSetting aging research/practice priorities will help maximize the benefits of research investment and provide valuable direction for allocating public and private research funds to areas of strategic importance.

Project description:Antidote stocking represents a major challenge to hospitals all over the world, including Kuwait. In order to assist hospitals to reduce costs and improve patient care, an essential antidote list can be used as an initial foundation for securing sufficient antidote availability at healthcare institutions. The aim of our study is to generate a nationally relevant essential antidote list for emergency care hospitals in Kuwait using the e-Delphi method by establishing consensus through a multidisciplinary expert group of healthcare providers. An electronic survey with 47 essential antidotes was developed. The e-Delphi method was used, with three rounds of voting, to determine expert consensus on an essential antidote list for hospitals in Kuwait. A purposive sample of healthcare professionals from governmental and private hospitals were selected for this study (n = 30). Consensus was gained if ≥75% of the expert panel agreed on the inclusion of the antidote, without any strong disagreements. Round 1 of the e-Delphi resulted in 41 antidotes reaching consensus and seven new antidotes suggested by the expert panel. Round 2 had two antidotes (out of seven newly suggested ones) reaching consensus. Round 3 was a confirmatory round, where the expert group agreed on their previous rounds' opinions. This resulted in the development of an essential antidote list with 43 antidotes. The optimal approach for ensuring adequate availability of antidotes is continuous monitoring of local poisoning incidence and antidote requirements through collaborations between academic researchers and emergency care clinicians. The development of an essential antidote list, with expert consensus, is one of the initial steps in securing a foundation for appropriate provision of antidotes at all healthcare institutions. This is the first study that the authors are aware of that demonstrates that the e-Delphi technique can consolidate recommendations of experts in emergency medicine to provide a list of essential antidotes.

Project description:The concept of psoriatic arthritis (PsA) prevention is gaining increased interest owing to the physical limitation, poor quality of life and low remission rates that are achieved with current therapies for PsA. The psoriasis-to-PsA transition offers a unique opportunity to identify individuals at increased risk of developing PsA and to implement preventive strategies. However, identifying individuals at increased risk of developing PsA is challenging as there is no consensus on how this population should be defined. This Consensus Statement puts forward recommended terminology from the Psoriasis and Psoriatic Arthritis Clinics Multicenter Advancement Network (PPACMAN) for defining specific subgroups of individuals during the preclinical and early clinical phases of PsA to be used in research studies. Following a three-round Delphi process, consensus was reached for three terms and definitions: 'increased risk for PsA', 'psoriasis with asymptomatic synovio-entheseal imaging abnormalities' and 'psoriasis with musculoskeletal symptoms not explained by other diagnosis'. These terms and their definitions will enable improved identification and standardization of study populations in clinical research. In the future, as increasing evidence emerges regarding the molecular and clinical features of the psoriasis-to-PsA continuum, these terms and definitions will be further refined and updated.

Project description:AimsThere is considerable controversy regarding optimal management of patients with paraesophageal hiatus hernia (pHH). This survey aims at identifying recommended strategies for work-up, surgical therapy, and postoperative follow-up using Delphi methodology.MethodsWe conducted a 2-round, 33-question, web-based Delphi survey on perioperative management (preoperative work-up, surgical procedure and follow-up) of non-revisional, elective pHH among European surgeons with expertise in upper-GI. Responses were graded on a 5-point Likert scale and analyzed using descriptive statistics. Items from the questionnaire were defined as "recommended" or "discouraged" if positive or negative concordance among participants was > 75%. Items with lower concordance levels were labelled "acceptable" (neither recommended nor discouraged).ResultsSeventy-two surgeons with a median (IQR) experience of 23 (14-30) years from 17 European countries participated (response rate 60%). The annual median (IQR) individual and institutional caseload was 25 (15-36) and 40 (28-60) pHH-surgeries, respectively. After Delphi round 2, "recommended" strategies were defined for preoperative work-up (endoscopy), indication for surgery (typical symptoms and/or chronic anemia), surgical dissection (hernia sac dissection and resection, preservation of the vagal nerves, crural fascia and pleura, resection of retrocardial lipoma) and reconstruction (posterior crurorrhaphy with single stitches, lower esophageal sphincter augmentation (Nissen or Toupet), and postoperative follow-up (contrast radiography). In addition, we identified "discouraged" strategies for preoperative work-up (endosonography), and surgical reconstruction (crurorrhaphy with running sutures, tension-free hiatus repair with mesh only). In contrast, many items from the questionnaire including most details of mesh augmentation (indication, material, shape, placement, and fixation technique) were "acceptable".ConclusionsThis multinational European Delphi survey represents the first expert-led process to identify recommended strategies for the management of pHH. Our work may be useful in clinical practice to guide the diagnostic process, increase procedural consistency and standardization, and to foster collaborative research.
