The Delphi technique is a systematic process of forecasting using the collective opinion panel members. structured method developing consensus among members methodology has gained acceptance in diverse fields medicine. methods assumed pivotal role last few decades to develop best practice guidance intelligence where research limited, ethically/logistically difficult or evidence conflicting. However, attempts assess quality standard studies have reported significant variance, and details followed are usually unclear. We recommend tools for evaluation methodology; identification problem area research, selection panel, anonymity panelists, controlled feedback, iterative rounds, criteria, analysis consensus, closing stability results. Based on these nine qualitative points, we assessed medical field related coronavirus disease 2019. There was inconsistency reporting vital elements such as members, defining criteria presenting propose our points researchers, journal editorial boards, reviewers evaluate healthcare research.

To evaluate whether the Morphological Uterus Sonographic Assessment (MUSA) features of adenomyosis need to be better defined and, if deemed necessary, reach consensus on updated definitions.A modified Delphi procedure was performed among European gynecologists with expertise in ultrasound diagnosis adenomyosis. identify MUSA that might revision, 15 two-dimensional (2D) video recordings (four also included three-dimensional (3D) still images) transvaginal (TVS) examinations uterus were presented first round (online questionnaire). Experts asked confirm or refute presence each nine (described original statement) videoclips and provide comments. In second questionnaire), results suggestions for revision shared experts before they assess a new set 2D 3D images TVS feedback proposed revisions. A third (virtual group meeting) conducted discuss final revised definitions features.

Essential Emergency and Critical Care: a consensus among global clinical experts

BMJ Global Health, Год журнала: 2021, Номер 6(9), С. e006585 - e006585

Опубликована: Сен. 1, 2021

Background Globally, critical illness results in millions of deaths every year. Although many these are potentially preventable, the basic, life-saving care critically ill patients often overlooked health systems. Essential Emergency and Critical Care (EECC) has been devised as that should be provided to all hospitals world. EECC includes effective low cost complexity for identification treatment across medical specialties. This study aimed specify content additionally, given surge ongoing pandemic, essential diagnosis-specific with COVID-19. Methods In a Delphi process, consensus (>90% agreement) was sought from diverse panel global clinical experts. The iteratively rated proposed treatments actions based on previous guidelines WHO/ICRC’s Basic Care. output adapted specialist reviewers into coherent feasible package processes plus list hospital readiness requirements. Results 269 experts had experience different acute specialties 59 countries resource settings. agreed contains 40 67 requirements, additions specific Conclusion specified patients. Implementing could an strategy policy makers reduce preventable worldwide.

Sustainability, Год журнала: 2023, Номер 15(14), С. 11277 - 11277

Опубликована: Июль 19, 2023

The discipline of Landscape Architecture (LA) is currently expanding its disciplinary boundary. supporting Technology in LA (TLA) always evolving and optimized to solve environmental problems. Considering the uncertain classification current knowledge for education importance technology education, a refined framework needed. This research first established Network Model (NMTLA) using Analysis (NA) expert interviews. Then, this proposed an Education Framework (EFLA) based on NMTLA. To build NMTLA, identified 23 key categories TLA through content analysis secondary research. interview network theory were used analyze visualize relationships among categories. By examining degree centrality, closeness betweenness centrality different TLA, study developed EFLA which summarizes twenty-three into four domains: core techniques, applied technologies, integrated specific technologies. also proposes series suggestions how apply today’s future education. NMTLA can contribute development higher They potentially address Sustainable Development Goals (SDGs) industry. However, scope limited USA, could be expanded include worldwide perspective enhance validity conclusions, larger sample size interviews should employed further studies.

There is a significant deficiency in addressing the unique characteristics of construction and demolition waste (C&DW) United Kingdom (UK) as it remains primary contributor to landfills. Circular economy (CE) practices are explored address this risk shortfall management comprehend reduction strategies for C&DW. Using Fuzzy Delphi approach, study maps assesses uncertainties associated with identifying indicators ranked CE adoption barriers achieve agreement twelve respondents. Consensus was also achieved C&DW measurement indicators. Concurrently, eleven separate interviews were conducted understand CE's effectiveness improving management. The results indicated that most barrier inefficient recycling policies ensure high-quality recycled materials. findings underscore influence design, managerial, legal surpasses social, knowledge, culture. Despite highlighting focus on recycling, reusing, reducing raw materials, deeply established tendencies prioritise linear economic models exist widely, resource conservation less considered. This provides concrete implementation responsible consumption production, challenges adoption, offers 25 industry-specific measuring implementation.

Опубликована: Янв. 12, 2024

Anxiety disorders are very prevalent and often persistent mental disorders, with a considerable rate of treatment resistance which requires regulatory clinical trials innovative therapeutic interventions. However, an explicit definition treatment-resistant anxiety (TR-AD) informing such is currently lacking. We used Delphi method-based consensus approach to provide internationally agreed, consistent clinically useful operational criteria for TR-AD in adults. Following summary the current state knowledge based on international guidelines available systematic review, survey free-text responses 29-item questionnaire relevant aspects TR-AD, online meeting, panel 36 multidisciplinary experts stakeholders voted anonymously written statements three rounds. Consensus was defined as ≥75% agreeing statement. The agreed set 14 recommendations providing detailed pharmacological and/or psychotherapeutic treatment, well potential staging model. also evaluated further regarding epidemiological subgroups, comorbidities biographical factors, terminology vs. "difficult-to-treat" preferences attitudes persons these future research directions. This expected serve systematic, practical guideline aid designing mechanistic studies facilitate purposes. effort could ultimately lead development more effective evidence-based stepped-care algorithms patients disorders.
