    PubMed Central

    Richardson, Craig; Borland, Christine

    2015-01-01

    This Introduction and interview discusses the poetical and empathic insights that are a key to the effectiveness of contemporary artist Christine Borland's practice and its relevance to the medical humanities, visual art research and medical students’ training. It takes place in a context of intensive interest in reciprocity and conversation as well as expert exchange between the fields of Medicine and Contemporary Arts. The interview develops an understanding of medical research and the application of its historical resources and contemporary practice-based research in contemporary art gallery exhibitions. Artists tend not to follow prescriptive programmes towards new historical knowledge, however, a desire to form productive relationships between history and contemporary art practice does reveal practical advantages. Borland's research also includes investigations in anatomy, medical practices and conservation.

    Background Accurate modeling of electrostatic potential and corresponding energies becomes increasingly important for understanding properties of biological macromolecules and their complexes. However, this is not an easy task due to the irregular shape of biological entities and the presence of water and mobile ions. Results Here we report a comprehensive suite for the well-known Poisson-Boltzmann solver, DelPhi, enriched with additional features to facilitate DelPhi usage. The suite allows for easy download of both DelPhi executable files and source code along with a makefile for local installations. The users can obtain the DelPhi manual and parameter files required for the corresponding investigation. Non-experienced researchers can download examples containing all necessary data to carry out DelPhi runs on a set of selected examples illustrating various DelPhi features and demonstrating DelPhi’s accuracy against analytical solutions. Conclusions DelPhi suite offers not only the DelPhi executable and sources files, examples and parameter files, but also provides links to third party developed resources either utilizing DelPhi or providing plugins for DelPhi. In addition, the users and developers are offered a forum to share ideas, resolve issues, report bugs and seek help with respect to the DelPhi package.

    1998-12-31

    The US Department of Energy (DOE) Federal Energy Technology Center is sponsoring a full-scale technology demonstration of Delphi Research, Inc.`s patented DETOX{sup SM} catalytic wet chemical oxidation waste treatment process at the Savannah River Site (SRS) in South Carolina. The process is being developed primarily to treat hazardous and mixed wastes within the DOE complex as an alternative to incineration, but it has significant potential to treat wastes in the commercial sector. The results of the demonstration will be intensively studied and used to validate the technology. A critical objective in preparing for the demonstration was the successful completion of a programmatic Operational Readiness Review. Readiness Reviews are required by DOE for all new process startups. The Readiness Review provided the vehicle to ensure that Delphi was ready to start up and operate the DETOX{sup SM} process in the safest manner possible by implementing industry accepted management practices for safe operation. This paper provides an overview of the DETOX{sup SM} demonstration at SRS, and describes the crucial areas of the Readiness Review that marked the first steps in Delphi`s transition from a technology developer to an operating waste treatment services provider.

    A Ring Imaging Cherenkov (RICH) detector system has been built and is now in full operation within the DELPHI experiment. Large data samples of Z{sup 0} decays are being collected with good resolution on the observed Cherenkov angles. Several studies of Z{sup 0} decays using the RICH have already been performed on limited samples. Disturbance of the detector operation caused by shrinkage of polymeric construction materials and by migration of radiator substance is reported. These effects have been counteracted and do not endanger the quality of the data.

  17. Measurement of |Vcs| with DELPHI experiment

    NASA Astrophysics Data System (ADS)

    1998-10-01

    Pair production of charged weak bosons W+/- at LEP2 collider can be exploited to measure the absolute value of the Vcs element of Cabbibo-Kobayashi-Maskawa matrix. The value can be most accurately extracted from the measured hadronic branching ratio of W+/- bosons. An independent method to obtain the |Vcs| value consists of tagging the flavour of primary quarks in jets, produced in W+/- decays. Using both methods on the data collected with DELPHI experiment during 1996 and 1997 runs, we obtained |Vcs|=0.99+/-0.06(stat.)+/-0.04(syst.). Combined result of |Vcs| measurements with four LEP experiments enables a test of CKM matrix unitarity.

    1995-08-01

    The performance of the High-density Projection Chamber (HPC), the barrel electromagnetic calorimeter of the DELPHI experiment, is described. The detector adopts the time projection technique in order to obtain exceptionally fine spatial granularity in the three coordinates ({approximately}2{times}20 mrad{sup 2} in {theta}{times}{phi} with nine samplings along the shower axes), using a limited number of readout channels (18,432). Among the various topics concerning the HPC construction and operation, major emphasis is given to the aspects related to the calibration in energy of the calorimeter, based mainly on the analysis of the detector response to {sup 83m}Kr decays, and to the treatment of aging in the readout proportional counters.

    2015-01-01

    The extent of consensus (or the lack thereof) among experts in emerging fields of innovation can serve as antecedents of scientific, societal, investor and stakeholder synergy or conflict. Naturally, how we measure consensus is of great importance to science and technology strategic foresight. The Delphi methodology is a widely used anonymous survey technique to evaluate consensus among a panel of experts. Surprisingly, there is little guidance on how indices of consensus can be influenced by parameters of the Delphi survey itself. We simulated a classic three-round Delphi survey building on the concept of clustered consensus/dissensus. We evaluated three study characteristics that are pertinent for design of Delphi foresight research: (1) the number of survey questions, (2) the sample size, and (3) the extent to which experts conform to group opinion (the Group Conformity Index) in a Delphi study. Their impacts on the following nine Delphi consensus indices were then examined in 1000 simulations: Clustered Mode, Clustered Pairwise Agreement, Conger’s Kappa, De Moivre index, Extremities Version of the Clustered Pairwise Agreement, Fleiss’ Kappa, Mode, the Interquartile Range and Pairwise Agreement. The dependency of a consensus index on the Delphi survey characteristics was expressed from 0.000 (no dependency) to 1.000 (full dependency). The number of questions (range: 6 to 40) in a survey did not have a notable impact whereby the dependency values remained below 0.030. The variation in sample size (range: 6 to 50) displayed the top three impacts for the Interquartile Range, the Clustered Mode and the Mode (dependency = 0.396, 0.130, 0.116, respectively). The Group Conformity Index, a construct akin to measuring stubbornness/flexibility of experts’ opinions, greatly impacted all nine Delphi consensus indices (dependency = 0.200 to 0.504), except the Extremity CPWA and the Interquartile Range that were impacted only beyond the first decimal point (dependency

  1. DELPHI: An introduction to output layout and data content

    SciTech Connect

    Smith, C.F.

    1994-08-16

    DELPHI was the data summary and interpretation code used by gas diagnostics personnel during the period from 1968 through 1986. It was written by Floyd Momyer, and went through several revisions during its period of use. Described here is the final version, which provided the most extensive set of summary tables. Earlier versions of the code lacked some of the capabilities of the final version, but what they did include was of substantially the same format. DELPHI was run against most available input decks in the mid 1980s. Microfiche and hardcopy output were generated. Both now reside in our archives. These reruns used modified input decks, which may not have had the proper {open_quotes}trigger{close_quotes} to instruct DELPHI to output some tables. These tables could, therefore be missing from a printout even though the necessary data was present. Also, modifications to DELPHI did, in some instances, eliminate DELPHIs` capability to correctly output some of the earlier optional tables. This monologue is intended to compliment the archived printout, and to provide enough insight so that someone unfamiliar with the techniques of Gas Diagnostics can retrieve the results at some future date. DELPHI last ran on the CDC-7600 machines, and was not converted to run on the Crays when the CDC-7600`s were decommissioned. DELPHI accepted data from various analytical systems, set up data summary tables, and combined preshot tracer and detector data with these results to calculate the total production of measured species and the indicated fission yields and detector conversions.

  2. Delphi technique used in laser incident surveillance

    NASA Astrophysics Data System (ADS)

    Clark, Krystyn R.; Johnson, Thomas E.; Neal, Thomas A.

    2004-07-01

    There are several data sources for collecting laser incidents. All reviewed sources collect information differently for varying purposes. An effort was undertaken to combine laser exposure reporting data into a single database so that trends in laser incidents could be identified. A review of available datasets revealed significant disparities in laser exposure reporting. As a result, utilizing the existing database to predict personnel at increased risk for laser exposure and injury is challenging if not impossible. For example, many of the data sources do not contain information about physical examinations, diagnosis, or medical follow-up, which are important for studying laser injury outcomes. This study proposes using the Delphi Technique to identify relevant fields that should be collected for a laser incident database based on the experiences of three groups of United States Air Force (USAF) professionals: (1) Engineers (Bioenvironmental Engineers), (2) Health Physicists, and (3) Physicians (Ophthalmologists and Flight Surgeons). In broad terms, these three professional groups coordinate laser incident analyses and investigations. Knowing what information is most important for studying laser incidents is the first step in establishing an effective database that will assist in identifying occupations that are at high-risk for laser injury. Robust data sets obtained for analysis by these healthcare professionals can be an effective tool for laser injury prevention and management.

    Leitch, J.A.; Leistritz, F.L.

    1984-01-01

    A Delphi-type survey and a consensus-building workshop were carried out to identify the most significant natural resource issues and problems emerging in the Great Plains and Rocky Mountain states. Approximately 107 issues initially were identified through a literature search and an inquiry Delphi round. Delphi round enabled the list to be narrowed to 25 issues. While consensus was found on the top 25 issues as a group, neither the Delphi panel nor the workshop participants agreed on the top five. Specific issues related to water and energy comprised the majority of those identified as most significant. Overall, the Delphi method appears to be a powerful and flexible tool for evaluating emerging environmental issues and problems. The analysis suggests that Delphi findings are quite robust with respect to minor changes in panel composition. Delphi thus appears to be an approach that may find increasing application in environmental policy analysis. 11 references, 3 figures, 4 tables.

  3. Delphi technique in environmental assessment. I. Implementation and effectiveness

    SciTech Connect

    Richey, J.S.; Mar, B.W.; Horner, R.R.

    1985-09-01

    The effectiveness with which a panel of experts, operating within the context of a Delphi technique, could be used to develop information for use in environmental monitoring program design and environmental decision-making was investigated. The Delphi technique was evaluated to determine selection criteria for an expert panel, how many panelists are necessary, what types of information can be considered effectively, and how many iterations are necessary. Small panels consisting of less than 10 individuals representing a variety of areas of experiences appeared sufficient for developing information about conceptual or philosophical issues. Neither large (e.g. 60 persons) nor small panels were effective for considering factual or data-based issues. Two iterations (i.e. an initial questionnaire with one follow-up) were adequate to determine the panel consensus. The costs of this implementation were compared with two other information-gathering techniques, the nominal group technique and retention of expert consultants. The costs of implementing the Delphi technique were between 10 and 60% of the costs of the two other methods. The Delphi method can provide an alternative or complementary means of accessing expert opinion at a reasonable cost. 9 references, 2 tables.

  14. How to use the nominal group and Delphi techniques.

    PubMed

    McMillan, Sara S; King, Michelle; Tully, Mary P

    2016-06-01

    Introduction The Nominal Group Technique (NGT) and Delphi Technique are consensus methods used in research that is directed at problem-solving, idea-generation, or determining priorities. While consensus methods are commonly used in health services literature, few studies in pharmacy practice use these methods. This paper provides an overview of the NGT and Delphi technique, including the steps involved and the types of research questions best suited to each method, with examples from the pharmacy literature. Methodology The NGT entails face-to-face discussion in small groups, and provides a prompt result for researchers. The classic NGT involves four key stages: silent generation, round robin, clarification and voting (ranking). Variations have occurred in relation to generating ideas, and how 'consensus' is obtained from participants. The Delphi technique uses a multistage self-completed questionnaire with individual feedback, to determine consensus from a larger group of 'experts.' Questionnaires have been mailed, or more recently, e-mailed to participants. When to use The NGT has been used to explore consumer and stakeholder views, while the Delphi technique is commonly used to develop guidelines with health professionals. Method choice is influenced by various factors, including the research question, the perception of consensus required, and associated practicalities such as time and geography. Limitations The NGT requires participants to personally attend a meeting. This may prove difficult to organise and geography may limit attendance. The Delphi technique can take weeks or months to conclude, especially if multiple rounds are required, and may be complex for lay people to complete. PMID:26846316

Further, a guidebook for its implementation was prepared including a road map and performance measurement. Results: The research led to the development of a context-specific model of quality management for healthcare organisations and a series of guidelines for its implementation. Conclusion: A proper model of quality management should be developed and implemented properly in healthcare organisations to achieve business excellence. PMID:24596883

  16. Basic concepts and architectural details of the Delphi trigger system

    SciTech Connect

    Bocci, V.; Booth, P.S.L.; Bozzo, M. |

    1995-08-01

    Delphi (DEtector with Lepton, Photon and Hadron Identification) is one of the four experiments of the LEP (Large Electron Positron) collider at CERN. The detector is laid out to provide a nearly 4 {pi} coverage for charged particle tracking, electromagnetic, hadronic calorimetry and extended particle identification. The trigger system consists of four levels. The first two are synchronous with the BCO (Beam Cross Over) and rely on hardwired control units, while the last two are performed asynchronously with respect to the BCO and are driven by the Delphi host computers. The aim of this paper is to give a comprehensive global view of the trigger system architecture, presenting in detail the first two levels, their various hardware components and the latest modifications introduced in order to improve their performance and make more user friendly the whole software user interface.

  17. UTC Power/Delphi SECA CBS Final Report

    SciTech Connect

    Gorman, Michael; Kerr, Rich

    2013-04-04

    The subject report summarizes the results of solid oxide fuel cell development conducted by UTC Power in conjunction with Delphi Automotive Systems under a cost-share program with from October 2008 through March of 2013. Over that period Delphi Automotive Systems developed a nearly four times larger area solid oxide fuel cell stack capable of operating on pre-reformed natural gas and simulated coal gas with durability demonstrated to 5,000 hours and projected to exceed 10,000 hours. The new stack design was scaled to 40-cell stacks with power output in excess of 6.25kW. Delphi also made significant strides in improving the manufacturability, yield and production cost of these solid oxide fuel cells over the course of the program. Concurrently, UTC Power developed a conceptual design for a 120 MW Integrated Gasification Fuel Cell (IGFC) operating on coal syngas with as high as 57% Higher Heating Value (HHV) efficiency as a measure of the feasibility of the technology. Subsequently a 400 kW on-site system preliminary design with 55% Lower Heating Value (LHV) efficiency operating on natural gas was down-selected from eighteen candidate designs. That design was used as the basis for a 25kW breadboard power plant incorporating four Delphi cell stacks that was tested on natural gas before the program was discontinued due to the sale of UTC Power in early 2013. Though the program was cut short of the endurance target of 3,000 hours, many aspects of the technology were proven including: large-area, repeatable cell manufacture, cell stack operation on simulated coal gas and natural gas and integrated power plant operation on natural gas. The potential of the technology for high efficiency stationary electric power generation is clear. Acceptable production costs, durability, and reliability in real world environments are the remaining challenges to commercialization.

  20. Delphi survey of priorities in clinical nursing research.

    PubMed

    Lindeman, C A

    1975-01-01

    Using the Delphi technique, a panel of 433 nurse and nonnurse experts was surveyed regarding priorities for clinical research in nursing. Of these, 341 completed all four Delphi survey rounds. Three questions were studied: 1) Is this an area in which nursing should assume primary research responsibility? 2) How important is research on this topic for the profession of nursing? 3) What is the likelihood of change in patient welfare because of research on the topic? Although the nature and amount of data produced prohibited interpretation of the data or delineation of succinct conclusions about priorities for clinical nursing research, responses to the three questions supported these statements: The majority of research areas identified in the questionnaire are areas in which nursing should take research leadership. Although there is some overlap, priorities for professional significance and social or patient welfare relevance are different. In terms of professional significance, highest priority was given to items regarding measuring the quality of care, role, nursing process, and the research process. In terms of patient welfare, several programs of research are discernible in the items ranked in the top ten percent; these include nursing interventions related to stress, care of the aged, pain, and patient education. The Delphi technique also is described. PMID:1042714

    This paper reports a study of the characteristics of psychological abuse strategies deployed in the workplace (mobbing or workplace bullying). Based on a literature review, the aim of the present study is two fold: firstly to propose a new taxonomy of mobbing strategies and to provide an operational definition for each of them, and secondly, to assess this taxonomy with the aid of several experts, by using a Delphi survey, and to evaluate the severity of each of the mobbing strategies. The experts were asked to evaluate the adequacy and the severity of the definitions for each mobbing strategy. Thirty experts working in various professions (psychology, medicine, law, sociology, etc.) participated in a two-round Delphi survey. The experts estimated that the new taxonomy and the operational definitions were appropriate, establishing content and construct validity. They ranked the workplace bullying strategies in terms of descending importance: strategies of direct nature, followed by indirect strategies. Theoretical implications of the study, its limitations and future research are discussed. PMID:20480698

    The paper presents the results and evaluations of a comprehensive set of neutron noise measurements on the Delphi subcritical assembly of the Delft Univ. of Technology. The measurements investigated the effect of different source distributions (inherent spontaneous fission and {sup 252}Cf) and the position of the detectors applied (both radially and vertically). The evaluation of the measured data has been performed by the variance-to-mean ratio (VTMR, Feynman-{alpha}), the autocorrelation (ACF, Rossi-{alpha}) and the cross-correlation (CCF) methods. The values obtained for the prompt decay constant show a strong bias, which depends both on the detector position and on the source distribution. This is due to the presence of higher modes in the system. It has been observed that the {alpha} value fitted is higher when the detector is close to the boundary of the core or to the {sup 252}Cf point-source. The higher alpha-modes have also been observed by fitting functions describing two alpha-modes. The successful set of measurement also provides a good basis for further theoretical investigations including the Monte Carlo simulation of the noise measurements and the calculation of the alpha-modes in the Delphi subcritical assembly.

    In the framework of Minimal Supersymmetric Standard Model (MSSM), gravitino interactions at ordinary energies are only important in the limit M_tilde G arrow 0. However, in the context of the Gauge Mediated Supersymmetry Breaking models, which favor M_tilde G > ~ 1 eV, the gravitino could be the Lightest Supersymmetric Particle (LSP) and the decay of the Next to LSP into gravitino would be accessible at LEP. The decay tilde τ arrow τ tilde G was searched for with the DELPHI detector, in the range M_tilde G <= 100 eV. For very short tilde τ decay lengths the analysis makes use of a method based on track impact parameters. For longer lifetimes, these decays are expected to take place within the tracking detector volume and therefore the decay vertices should be reconstructed. The results obtained by these two analyses are combined with those of the searches for heavy stable charged particles and for conventional MSSM tilde τ decays, in order to set limits on M_tildeτ irrespective of the gravitino mass. The results obtained using the data collected by DELPHI during the LEP II runs at center of mass energies from 130 to 184 GeV will be presented.

    In this article we aim to demonstrate how Gadamerian philosophical hermeneutics may provide a sound methodological framework for researchers using the Delphi Technique (Delphi) in studies exploring health and well-being. Reporting of the use of Delphi in health and well-being research is increasing, but less attention has been given to covering its methodological underpinnings. In Delphi, a structured anonymous conversation between participants is facilitated, via an iterative survey process. Participants are specifically selected for their knowledge and experience with the topic of interest. The purpose of structuring conversation in this manner is to cultivate collective opinion and highlight areas of disagreement, using a process that minimizes the influence of group dynamics. The underlying premise is that the opinion of a collective is more useful than that of an individual. In designing our study into health literacy, Delphi aligned well with our research focus and would enable us to capture collective views. However, we were interested in the methodology that would inform our study. As researchers, we believe that methodology provides the framework and principles for a study and is integral to research integrity. In assessing the suitability of Delphi for our research purpose, we found little information about underpinning methodology. The absence of a universally recognized or consistent methodology associated with Delphi was highlighted through a scoping review we undertook to assist us in our methodological thinking. This led us to consider alternative methodologies, which might be congruent with the key principles of Delphi. We identified Gadamerian philosophical hermeneutics as a methodology that could provide a supportive framework and principles. We suggest that this methodology may be useful in health and well-being studies utilizing the Delphi method. PMID:25948132

    Pair production of charged weak bosons W{sup {+-}} at LEP2 collider can be exploited to measure the absolute value of the V{sub cs} element of Cabbibo-Kobayashi-Maskawa matrix. The value can be most accurately extracted from the measured hadronic branching ratio of W{sup {+-}} bosons. An independent method to obtain the |V{sub cs}| value consists of tagging the flavour of primary quarks in jets, produced in W{sup {+-}} decays. Using both methods on the data collected with DELPHI experiment during 1996 and 1997 runs, we obtained |V{sub cs}|=0.99{+-}0.06(stat.){+-}0.04(syst.). Combined result of |V{sub cs}| measurements with four LEP experiments enables a test of CKM matrix unitarity.

    To improve the identification and separation of leptons in the Hadron Calorimeter of DELPHI, one of the four LEP experiments at CERN, the possibility of a direct read-out of the cathodes of the 20,000 limited streamer tubes was studied and successfully tested on a small scale. A larger scale test started in June 1994. This new system which is independent of the present pad read-out provides a ``yes/no`` information. The combination of both read-out systems makes it possible to use the Hadron Calorimeter as a track detector. The result of these test show that the cathode read-out provides a better {pi}/{micro} separation, and improved detection of neutral long lived particles, enhanced discrimination of two showers and a more precise hadron energy measurement. It was decided to equip the whole detector with the new read-out, starting during the 94/95 shutdown.

    The DELPHI STIC detector is a lead-scintillator sampling calorimeter with wave length shifting optical fibers used for light collection. The main goal of the calorimeter at LEP100 is to measure the luminosity with an accuracy better than 0.1%. The detector has been in operation since the 1994 LEP run. Presented here is the performance measured during the 1994--1995 LEP runs, with the emphasis on the achieved energy and space resolution, the long-term stability and the efficiency of the detector. The new bunchtrains mode of LEP requires a rather sophisticated trigger and timing scheme which is also presented. To control the trigger efficiency and stability of the calorimeter channels, a LED-based monitoring system has been developed.

    Objective The aim of this research study was to identify the core competencies for health education teachers in supporting the development of health literacy among their students. Method/Results A three round Delphi method was employed. Experts in health education were asked to identify core competencies for school health educators. Twenty six participants from the academic field were invited to participate in the study. Twenty participants completed the first round of the Delphi, while eighteen took part in round two and fifteen participated in the final round. Data were collected using an electronic questionnaire. The first round contained an open ended question in which participants were asked to name and define all the competencies they perceived were important. Thematic analysis was undertaken on these data. A list of 36 competencies was created from this round. This list was then returned to the same participants and they were asked to rate each competency on a 7 point semantic differential scale in terms of importance. The resulting data were then analysed. For the final round, participants were presented with a list of 33 competencies and were asked to rank them again, in order of importance. Conclusion Twelve core competencies emerged from the analysis and these competencies comprised of a mixture of knowledge, attitude and skills. The authors suggest that how these competencies are achieved and operationalised in the school context can be quite complex and multi-faceted. While the authors do not seek to generalise from the study they suggest that these competencies are an important input for all stakeholders, in order to question national and international teacher guidelines. In addition the competencies identified may provide a useful starting point for others to undertake deeper analysis of what it means to be an effective health educator in schools. PMID:26630180

    Objectives To identify the tasks that should constitute the work of preregistration house officers to provide the basis for the development of a self evaluation instrument. Design Literature review and modified Delphi technique. Setting Northern Deanery within the Northern and Yorkshire office NHS executive. Subjects 67 educational supervisors of preregistration house officers. Main outcome measures Percentage of agreement by educational supervisors to tasks identified from the literature. Results Over 61% of communication items, 70% of on call patient care items, 75% of routine patient care items, 45% of practical procedure items, and over 63% of self management items achieved over 95% agreement that they should be part of the house job of preregistration house officers. Poor agreement was found for the laboratory and clinical investigations that house officers could perform with or without supervision. Conclusions The tasks of house officers were identified but issues in using this method and in devising a universally acceptable list of tasks for preregistration house officers were apparent. Key messagesMore than 100 activities were identified as potential tasks for house officers, and 11 personal abilities were identified as self management skillsThe ability of preregistration house officers to perform all of the tasks independently would be restricted by their experiences and therefore may depend on the specialty in which they workThe deliberation over what are and are not “shared tasks” was evident; some educational supervisors wanted the house officer to be capable of, but not practise, some tasks whereas others did not believe these tasks were within the remit of the house officerThe Delphi technique is a useful method for gaining the autonomous opinions of individuals from a large group of geographically distant members PMID:10417084

    The integrated control system of the DELPHI experiment is described. It allows the data to be taken in an almost automatic fashion. This is achieved by computer monitoring of the states of the LEP machine, the DELPHI subdetectors (SC) and the Data Acquisition System (DAS). Depending on these states, computer initiated actions are then taken. It has been designed using {open_quote}State Manager{close_quote} concept already used for local and central controls of DAS and SC.

    Introduction: The Department of Community Medicine and Family Medicine (CMFM) has been started as a new model for imparting the components of family medicine and delivering health-care services at primary and secondary levels in all six newly established All India Institute of Medical Sciences (AIIMS), but there is no competency-based curriculum for it. The paper aims to share the experience of Delphi method in the process of developing consensus on core competencies of the new model of CMFM in AIIMS for undergraduate medical students in India. Methods: The study adopted different approaches and methods, but Delphi was the most critical method used in this research. In Delphi, the experts were contacted by e-mail and their feedback on the same was analyzed. Results: Two rounds of Delphi were conducted in which 150 participants were contacted in Delphi-I but only 46 responded. In Delphi-II, 26 participants responded whose responses were finally considered for analysis. Three of the core competencies namely clinician, primary-care physician, and professionalism were agreed by all the participants, and the least agreement was observed in the competencies of epidemiologist and medical teacher. The experts having more experience were less consistent as responses were changed from agree to disagree in more than 15% of participants and 6% changed from disagree to agree. Conclusion: Within the given constraints, the final list of competencies and skills for the discipline of CMFM compiled after the Delphi process will provide a useful insight into the development of competency-based curriculum of the subject.

    The evaluation of sustainable tourism strategies promoted by National Parks (NP) related stakeholders is a key concern for NP managers. To help them in their strategic evaluation procedures, in this paper we propose a methodology based on the Analytic Network Process and a Delphi-type judgment-ensuring procedure. The approach aims at involving stakeholders in a participatory and consensus-building process. The methodology was applied to Los Roques NP in Venezuela. The problem included three sustainable tourism strategies defined by the stakeholders: eco-efficient resorts, eco-friendly leisure activities and ecological transportation systems. Representatives of eight stakeholders participated in the methodology. 13 sustainability criteria were selected. Results provide some important insights into the overall philosophy and underlying participants' conception of what sustainable development of Los Roques NP means. This conception is broadly shared by stakeholders as they coincided in the weights of most of the criteria, which were assigned individually through the questionnaire. It is particularly noteworthy that tourists and environmentalists almost fully match in their assessments of criteria but not of the alternatives. Moreover, there is a great agreement in the final assessment. This suggests that the regular contact among the different stakeholders, i.e. tourists with inhabitants, authorities with environmentalists, tour operators with representatives of the ministry, etc. has led to a common understanding of the opportunities and threats for the NP. They all agreed that the procedure enhances participation and transparency and it is a necessary source of information and support for their decisions.

    Abulia is the relatively uncommon yet debilitating lack of spontaneous, goal-directed behaviour that is seen predominantly with lesions of the basal ganglia and the frontal lobes. We sought to confirm the existence of abulia as an entity recognized by clinicians, to generate a set of items characteristic of the condition, and to see how clinicians differentiate between overlapping disorders. The Delphi technique was used to survey consultant neurologists and psychiatrists at three hospitals in London. The study consisted of two phases: semi- structured interviews of a small group of neurologists and psychiatrists, followed by a survey of a larger group of consultants using postal questionnaires. Both neurologists and psychiatrists recognized abulia to be a distinct clinical entity but its status as a syndrome was unclear. Features such as difficulty in initiating and sustaining spontaneous movements and reduction in emotional responsiveness, spontaneous speech, and social interaction were identified as being characteristic of abulia. The information generated by this study may help to develop a working classification for disorders of diminished drive and motivation, and instruments for clinical assessment and decision making.

    To identify components of a provisional clinical response index for thyroid eye disease (CRI-TED) using a modified Delphi technique. The International Thyroid Eye Disease Society (ITEDS) conducted a structured, 3-round Delphi exercise establishing consensus for a core set of measures for clinical trials in TED. The steering committee discussed the results in a face-to-face meeting (nominal group technique) and evaluated each criterion with respect to its feasibility, reliability, redundancy, and validity. Redundant measures were consolidated or excluded. Criteria were parsed into 11 domains for the Delphi surveys. Eighty four respondents participated in the Delphi-1 survey, providing 220 unique items. Ninety- two members (100% of the respondents from Delphi 1 plus eight new participants) responded in Delphi-2 and rated the same 220 items. Sixty-four members (76% of participants) rated 153 criteria in Delphi-3 (67 criteria were excluded due to redundancy). Criteria with a mean greater than 6 (1 least appropriate to 9 most appropriate) were further evaluated by the nominal group technique and provisional core measures were chosen. Using a Delphi exercise, we developed provisional core measures for assessing disease activity and severity in clinical trials of therapies for TED. These measures will be iteratively refined for use in multicenter clinical trials. PMID:19752424

    Pole, David L; Ando, Howard Y; Murphy, Sean T

    2007-01-01

    DELPHI is an expert system that has been developed to predict possible degradants of pharmaceutical compounds under stress testing conditions. It has been programmed with the objective of finding relevant degradation pathways, identifying degradant structures, and providing tools to the analytical chemist to assist in degradation identification. The system makes degradant predictions based on the chemical structure of the drug molecule and precedent from a broad survey of the literature. A description of DELPHI's treatment of molecular perception is described as are many features of the heuristic degradation rules it uses to capture and apply chemical degradation knowledge. DELPHI's utility for capturing institutional knowledge is discussed in relation to an analysis of degradation prediction results for 250 molecules of diverse chemical structure collected over 5 years of use. As such, it provides a reliable, convenient, and rapid tool for evaluating potential pathways of chemical instability of pharmaceuticals. PMID:17602568

    Background Evidence suggests that simulation leads to improved operative skill, shorter operating room time, and better patient outcomes. Currently, no standardized laparoscopy curriculum exists for gynecology residents. Objective To design a structured laparoscopy curriculum for gynecology residents using Delphi consensus methodology. Methods This study began with Delphi methodology to determine expert consensus on the components of a gynecology laparoscopic skills curriculum. We generated a list of cognitive content, technical skills, and nontechnical skills for training in laparoscopic surgery, and asked 39 experts in gynecologic education to rate the items on a Likert scale (1–5) for inclusion in the curriculum. Consensus was predefined as Cronbach α of ≥ 0.80. We then conducted another Delphi survey with 9 experienced users of laparoscopic virtual reality simulators to delineate relevant curricular tasks. Finally, a cross-sectional design defined benchmark scores for all identified tasks, with 10 experienced gynecologic surgeons performing the identified tasks at basic, intermediate, and advanced levels. Results Consensus (Cronbach α = 0.85) was achieved in the first round of the curriculum Delphi, and after 2 rounds (Cronbach α = 0.80) in the virtual reality curriculum Delphi. Consensus was reached for cognitive, technical, and nontechnical skills as well as for 6 virtual reality tasks. Median time and economy of movement scores defined benchmarks for all tasks. Conclusions This study used Delphi consensus to develop a comprehensive curriculum for teaching gynecologic laparoscopy. The curriculum conforms to current educational standards of proficiency-based training, and is suggested as a standard in residency programs. PMID:26221434

    2014-01-01

    Background Historically substance misuse has been relatively common in western countries, but comparatively few Finns report drug use. The Drugs 2020 study aimed at foreseeing changes in the drug situation in Finland by the year 2020. Methods The Delphi method was used, utilizing drug experts of the EU national network in Finland. Results Marked growth was foreseen in drug use, especially in synthetic designer drugs and misuse of medicinal drugs. Significant increase was also expected in growing cannabis at home. However, the control of drug market was expected to shift more into the hands of organized crime. No consensus was reached on how drug prices will develop in the time period. Drug use is likely to remain punishable although the use and possession of cannabis may be treated less severely. It seems likely that health and social services resources will be directed towards medicinal treatment. Conclusions Foresight can be utilized in preparing for the future; desirable developments can be fostered, and measures can be taken to curb probable but undesirable lines of development. Based on the results of this study, the experts’ view is that it is highly likely that the Finnish society will have to prepare for an increase in the demand for drug-related care, both in terms of content of the care and financing the services. Also, the forecasted increase in the role of legal prescription medicine used as intoxicants will call for efforts not only in changing prescription practices but in border and police control measures, as well. Parallel developments have been foreseen in the UK and Sweden, and it is likely that similar trends will actualize also in other western countries. PMID:24885142

    2014-01-01

    Context: Addressing clinical outcomes is paramount to providing effective health care, yet there is no consensus regarding the appropriate outcomes to address after ankle injuries. Compounding the problem is the repetitive nature of lateral ankle sprains, referred to as functional (FAI) or chronic (CAI) ankle instability. Although they are commonly used terms in practice and research, FAI and CAI are inconsistently defined and assessed. Objective: To establish definitions of a healthy/normal/noninjured ankle, FAI, and CAI, as well as their characteristics and assessment techniques. Design: Delphi study. Setting: Telephone interviews and electronic surveys. Patients or Other Participants: Sixteen experts representing the fields of ankle function and treatment, ankle research, and outcomes assessment and research were selected as panelists. Data Collection and Analysis: A telephone interview produced feedback regarding the definition of, functional characteristics of, and assessment techniques for a healthy/normal/noninjured ankle, an unhealthy/acutely injured ankle, and FAI/CAI. Those data were compiled, reduced, and returned through electronic surveys and were either included by reaching consensus (80% agreement) or excluded. Results: The definitions of a healthy/normal/noninjured ankle and FAI reached consensus. Experts did not agree on a definition of CAI. Eleven functional characteristics of a healthy/normal/noninjured ankle, 32 functional characteristics of an unhealthy/acutely injured ankle, and 13 characteristics of FAI were agreed upon. Conclusions: Although a consensus was reached regarding the definitions and functional characteristics of a healthy/normal/noninjured ankle and FAI, the experts could only agree on 1 characteristic to include in the FAI definition. Several experts did, however, provide additional comments that reinforced the differences in the interpretation of those concepts. Although the experts could not agree on the definition of CAI, its

  20. Single-photon events in the DELPHI experiment

    NASA Astrophysics Data System (ADS)

    Harris, Elisabeth Falk

    1998-08-01

    A series of studies pertaining to the STIC calorimeter at the DELPHI experiment at LEP is presented, and a new generation of fast wire scanners for emittance measurements at PS is described. The STIC studies are centered around a single-photon analysis, in which the reaction e+c/sp-/to/gamma + invisible particles was studied at center-of-mass energies of 161, 172 and 183 GeV. The cross section thus obtained was used to measure the number of neutrino families, and also to set limits on physics reactions occuring outside the framework of the Standard Model. The single-photon analysis is rendered difficult by an abundance of off-energy electron background. This type of background was examined in a separate series of Monte Carlo simulations, which are also reported. The STIC calorimeter modules have been equipped with a tracking device in the form of silicon-strip detectors, in order to improve the rejection of off-energy electrons in single-proton analyses. Results from a study of the performance of these detectors are presented. A method to reduce coherent noise in the silicon-strip detectors is also described. A new generation of fast wire scanners was installed at PS in 1994. The wire scanners are an important tool for measuring transverse beam profiles, from which transverse emittances are derived. An upgrade of a previous set of wire scanners was essential in order to obtain a reliable instrument that provides highly accurate emittance measurements, in particular in view of the future use of the PS accelerator complex as part of the injector chain for LHC. A presentation is given of the new instrument.

  8. The DELPHI distributed information system for exchanging LEP machine related information

    NASA Astrophysics Data System (ADS)

    Dönszelmann, M.; Gaspar, C.

    1994-12-01

    An information management system was designed and implemented to interchange information between the DELPHI experiment at CERN and the monitoring/control system for the LEP (Large Electron Positron Collider) accelerator. This system is distributed and communicates with many different sources and destinations (LEP) using different types of communication. The system itself communicates internally via a communication system based on a publish-and-subscribe mechanism, DIM (Distributed Information Manager). The information gathered by this system is used for on-line as well as off-line data analysis. Therefore it logs the information to a database and makes it available to operators and users via DUI (DELPHI User Interface). The latter was extended to be capable of displaying "time-evolution" plots. It also handles a protocol, implemented using a finite state machine, SMI (State Management Interface), for (semi-)automatic running of the Data Acquisition System and the Slow Controls System.

  9. Using a Delphi approach to develop a strategy for A&E in defence nursing.

    PubMed

    Kenward, Gary; Berry, Andy; Despres, Julian; McLeod, Judith

    The Armed Forces has seen an increase in the number of operational deployments overseas and a greater demand for Accident and Emergency (A&E) trained nurses. This article describes a modified Delphi study used to contribute to the development of a strategy for emergency nursing in the Defence Nursing Services. Twenty-eight A&E specialists took part and the key issues raised were recruitment and retention, staff development, new roles, research priorities, increased internal recruitment of A&E nurses to meet operational demands, and the need for a structured career pathway to help retention. The most pressing areas requiring research were evaluation of the nurse practitioner role, clinical competencies and managing heat injuries in the operational setting. The modified Delphi study provided a valuable and detailed insight into the challenges and aspirations of the military A&E nursing cadre and has assisted in developing a strategy for emergency nursing.

  10. Determinants of adolescents' ineffective and improved coping with cyberbullying: a Delphi study.

    PubMed

    Jacobs, Niels C L; Dehue, Francine; Völlink, Trijntje; Lechner, Lilian

    2014-06-01

    The study's aim was to obtain an overview of all relevant variables involved in ineffective coping behavior and improvement in coping behavior as it pertains to cyberbullying among adolescents, in order to systematically develop a theory- and evidence-based intervention. This was done by means of a three round online Delphi study. First, 20 key experts listed possible relevant determinants. Next, 70 experts scored these determinants on their relevance and finally, experts rerated relevance of each determinant based on group median scores. The experts agreed that 115 items are relevant for ineffective (62) or improvement in (53) coping behavior. New found determinants were the extent to which one can adjust behavior upon feedback, impulsivity, self-confidence, communication style, personality, decision-making skills, conflict resolution skills, previous participation in personal resilience training, social relationships, rumors and self-disclosure. We conclude that the Delphi technique is useful in discovering new and relevant determinants of behavior. PMID:24793384

    The Forward Ring Imaging Cherenkov detector covers both end-cap regions of the DELPHI experiment at LEP in the polar angel 15[degree] < [theta] < 35[degree] and 145[degree] < [theta] < 165[degree]. The detector combines a layer of liquid C[sub 6]F[sub 14] and a volume of gaseous C[sub 4]F[sub 10] into a single assembly. Ultraviolet photons from both radiators are converted in a single plane of photosensitive Time Projection Chambers. Identification of charged particles is provided for momenta up to 40 GeV/c. The design of the detector is briefly described. The detector is now fully installed in DELPHI and has participated in the 1993 data taking. The overall performance will be presented together with the expectations from Monte Carlo simulations. Results close to design values are obtained.

    Topics for theoretical teaching during the obstetrics and gynaecology specialty training programme are often chosen by tutors, with little input from the trainees. However, it is important to actively involve adults in their learning process to maintain their learning ownership and motivation. The Delphi methodology is a generic social science technique used to aggregate views and opinions of experts, the community and service users. In this study, we conducted a two generational Delphi study to achieve consensus between a group of trainees in obstetrics and gynaecology, regarding what they considered important topics for inclusion in their protected teaching programme. A total of 25 trainees from one deanery, participated in this study. We were able to produce a list of 26 topics in obstetrics and 30 in gynaecology, prioritised according to their importance for inclusion in the specialty protected teaching programme, as viewed by these trainees.

    The Delphi technique is a means of aggregating the judgement of a panel of experts in order to improve the quality of decision-making. This paper provides a case study of the technique by undertaking a three-round Delphi study to determine a package of best available techniques to reduce nitrogen emissions from a poultry unit under the Integrated Pollution Prevention and Control Directive (IPPC). Forms of nitrogen addressed included ammonia (NH3), nitrous oxide (N2O) nitrogen oxides (NOx), dusts and nitrate (NO3-), with the study providing a means to prioritise the pollution concerns on different spatial scales. The priority pollutant issues were the contribution of NH3 to eutrophication, the global cooling effect of NH4+ aerosol, the role of NH4+ as a vector for atmospheric transport of NOx and SO2, the contribution of N2O to global warming, and NO3- leaching. Reduced nitrogen (NHx) was rated as a priority on all scales, while N2O and NO3- were rated as priorities only on global and local scales, respectively. The study indicated the need for abatement techniques at each stage of poultry rearing and waste management, with particular attention to reduce NH3 emissions, reflecting the priority pollutant concerns. Measures identified by the panel include maintenance of dry litter, low emission removal of litter from housing and storage of litter under cover. Once the litter has left the farm, this should either be used as a biofuel for electricity generation or rapidly incorporated into agricultural soils. The amounts and timing of manure application should be tuned to crop needs. Uncertainties in the Delphi technique limit its suitability as a stand-alone decision making tool. However, the Delphi technique proved useful in identifying priority pollutant issues, areas of agreement, disagreement and where information is lacking. This demonstrates its use when dealing with the complex issues of prioritising pollution issues and abatement approaches. PMID:14680894

    Objective Identifying patient safety priorities in mental healthcare is an emerging issue. A variety of aspects of patient safety in medical care apply for patient safety in mental care as well. However, specific aspects may be different as a consequence of special characteristics of patients, setting and treatment. The aim of the present study was to combine knowledge from the field and research and bundle existing initiatives and projects to define patient safety priorities in mental healthcare in Switzerland. The present study draws on national expert panels, namely, round-table discussion and modified Delphi consensus method. Design As preparation for the modified Delphi questionnaire, two round-table discussions and one semistructured questionnaire were conducted. Preparative work was conducted between May 2015 and October 2015. The modified Delphi was conducted to gauge experts' opinion on priorities in patient safety in mental healthcare in Switzerland. In two independent rating rounds, experts made private ratings. The modified Delphi was conducted in winter 2015. Results Nine topics were defined along the treatment pathway: diagnostic errors, non-drug treatment errors, medication errors, errors related to coercive measures, errors related to aggression management against self and others, errors in treatment of suicidal patients, communication errors, errors at interfaces of care and structural errors. Conclusions Patient safety is considered as an important topic of quality in mental healthcare among experts, but it has been seriously neglected up until now. Activities in research and in practice are needed. Structural errors and diagnostics were given highest priority. From the topics identified, some are overlapping with important aspects of patient safety in medical care; however, some core aspects are unique. PMID:27496233

    2012-01-01

    Background Non-adherence to prescribed medication is a pervasive problem that can incur serious effects on patients’ health outcomes and well-being, and the availability of resources in healthcare systems. This study aimed to develop practical consensus-based policy solutions to address medicines non-adherence for Europe. Methods A four-round Delphi study was conducted. The Delphi Expert Panel comprised 50 participants from 14 countries and was representative of: patient/carers organisations; healthcare providers and professionals; commissioners and policy makers; academics; and industry representatives. Participants engaged in the study remotely, anonymously and electronically. Participants were invited to respond to open questions about the causes, consequences and solutions to medicines non-adherence. Subsequent rounds refined responses, and sought ratings of the relative importance, and operational and political feasibility of each potential solution to medicines non-adherence. Feedback of individual and group responses was provided to participants after each round. Members of the Delphi Expert Panel and members of the research group participated in a consensus meeting upon completion of the Delphi study to discuss and further refine the proposed policy solutions. Results 43 separate policy solutions to medication non-adherence were agreed by the Panel. 25 policy solutions were prioritised based on composite scores for importance, and operational and political feasibility. Prioritised policy solutions focused on interventions for patients, training for healthcare professionals, and actions to support partnership between patients and healthcare professionals. Few solutions concerned actions by governments, healthcare commissioners, or interventions at the system level. Conclusions Consensus about practical actions necessary to address non-adherence to medicines has been developed for Europe. These actions are also applicable to other regions. Prioritised

    Strategic Environmental Assessment (SEA) is a procedural tool and within the framework of SEA, several different types of analytical methods can be used in the assessment. However, the impact matrix used currently in Taiwan has some disadvantages. Hence, a Delphi-matrix approach to SEA is proposed here to improve the performance of Taiwan's SEA. This new approach is based on the impact matrix combination with indicators of sustainability, and then the Delphi method is employed to collect experts' opinions. In addition, the assessment of National Floriculture Park Plan and Taiwan Flora 2008 Program is taken as an example to examine this new method. Although international exhibition is one of the important tourism (economic) activities, SEA is seldom about tourism sector. Finally, the Delphi-matrix approach to SEA for tourism development plan is established containing eight assessment topics and 26 corresponding categories. In summary, three major types of impacts: resources' usages, pollution emissions, and local cultures change are found. Resources' usages, such as water, electricity, and natural gas demand, are calculated on a per capita basis. Various forms of pollution resulting from this plan, such as air, water, soil, waste, and noise, are also identified.

    Background Podoconiosis is one of the major causes of lymphoedema in the tropics. Nonetheless, currently there are no endemicity classifications or elimination targets to monitor the effects of interventions. This study aimed at establishing case definitions and indicators that can be used to assess endemicity, elimination and clinical outcomes of podoconiosis. Methods This paper describes the result of a Delphi technique used among 28 experts. A questionnaire outlining possible case definitions, endemicity classifications, elimination targets and clinical outcomes was developed. The questionnaire was distributed to experts working on podoconiosis and other neglected tropical diseases in two rounds. The experts rated the importance of case definitions, endemic classifications, elimination targets and the clinical outcome measures. Median and mode were used to describe the central tendency of expert responses. The coefficient of variation was used to describe the dispersals of expert responses. Results Consensus on definitions and indicators for assessing endemicity, elimination and clinical outcomes of podoconiosis directed at policy makers and health workers was achieved following the two rounds of Delphi approach among the experts. Conclusions Based on the two Delphi rounds we discuss potential indicators and endemicity classification of this disabling disease, and the ongoing challenges to its elimination in countries with the highest prevalence. Consensus will help to increase effectiveness of podoconiosis elimination efforts and ensure comparability of outcome data. PMID:26185194

    We present an alternative view of the active tectonics and landscape evolution of the Delphi archaeological site, located on the southern margin of Mt Parnassos, central Greece, based on detailed geological mapping. The tectonic grain of the area provides the key to understanding the nature and degree of tectonic activity and associated natural hazards in this worldwide famous site, on the northern margin of the Corinth Rift. The dominant structure is a gently north-dipping thrust fault (SPT), which marks the southern boundary of Mt Parnassos. This thrust brings the Mesozoic carbonates over the flysch members of the Parnassos Unit. Intense folding is observed at all scales and the hanging-wall of the thrust corresponds to an overturned anticline, thrusted over the flysch, the latter cropping out along the south-facing mountain slope and the adjacent valley of Pleistos. The hanging-wall block of the SPT is intensely fractured; a dominant set of steep discontinuities, east and west of the archaeological site has facilitated slope failure, with some of them accommodating minor amounts of dip-slip displacement. One of them is identified as an active structure ("Delphi Fault") exposed after road improvement works several years ago. This surface can be mapped for only ~150 m east and 1.3 km west of Delphi: detailed geological mapping showed that it invariably belongs to the hanging-wall of the SPT, which has a total length of ca 25 km. Slope failure processes, which appear to be dominant at least during the Upper Quaternary years have led to the accumulation of sizeable blocks (measuring from 0.2 - 3.5km2) which have slipped on the incompetent, impermeable clastics that form the footwall of the SPT. We therefore suggest that the structure identified as the "Delphi Fault" belongs to a set of subvertical discontinuities which have developed on the culmination of an overturned anticline, on the hanging-wall block of a major thrust fault. This surface is associated with

    Background: Excellence and quality models are comprehensive methods for improving the quality of healthcare. The aim of this study was to design excellence and quality model for training centers of primary health care using Delphi method. Methods: In this study, Delphi method was used. First, comprehensive information were collected using literature review. In extracted references, 39 models were identified from 34 countries and related sub-criteria and standards were extracted from 34 models (from primary 39 models). Then primary pattern including 8 criteria, 55 sub-criteria, and 236 standards was developed as a Delphi questionnaire and evaluated in four stages by 9 specialists of health care system in Tabriz and 50 specialists from all around the country. Results: Designed primary model (8 criteria, 55 sub-criteria, and 236 standards) were concluded with 8 criteria, 45 sub-criteria, and 192 standards after 4 stages of evaluations by specialists. Major criteria of the model are leadership, strategic and operational planning, resource management, information analysis, human resources management, process management, costumer results, and functional results, where the top score was assigned as 1000 by specialists. Functional results had the maximum score of 195 whereas planning had the minimum score of 60. Furthermore the most and the least sub-criteria was for leadership with 10 sub-criteria and strategic planning with 3 sub-criteria, respectively. Conclusion: The model that introduced in this research has been designed following 34 reference models of the world. This model could provide a proper frame for managers of health system in improving quality. PMID:26576350

    Background Groin pain in athletes occurs frequently and can be difficult to treat, which may partly be due to the lack of agreement on diagnostic terminology. Objective To perform a short Delphi survey on terminology agreement for groin pain in athletes by a group of experts. Methods A selected number of experts were invited to participate in a Delphi questionnaire. The study coordinator sent a questionnaire, which consisted of demographic questions and two ‘real-life’ case reports of athletes with groin pain. The experts were asked to complete the questionnaire and to provide the most likely diagnosis for each case. Questionnaire responses were analysed by an independent researcher. The Cohen's κ statistic was used to evaluate the level of agreement between the diagnostic terms provided by the experts. Results Twenty-three experts participated (96% of those invited). For case 1, experts provided 9 different terms to describe the most likely diagnosis; for case 2, 11 different terms were provided to describe the most likely diagnosis. With respect to the terms provided for the most likely diagnosis, the Cohen's κ was 0.06 and 0.002 for case 1 and 2, respectively. This heterogeneous taxonomy reflects only a slight agreement between the various diagnostic terms provided by the selected experts. Conclusions This short Delphi survey of two ‘typical, straightforward’ cases demonstrated major inconsistencies in the diagnostic terminology used by experts for groin pain in athletes. These results underscore the need for consensus on definitions and terminology on groin pain in athletes. PMID:25907180

    2016-01-01

    Background Academic detailing is an outreach education technique that combines the direct social marketing traditionally used by pharmaceutical representatives with unbiased content summarizing the best evidence for a given clinical issue. Academic detailing is conducted with clinicians to encourage evidence-based practice in order to improve the quality of care and patient outcomes. The adoption of academic detailing has increased substantially since the original studies in the 1980s. However, the lack of standard agreement on its implementation makes the evaluation of academic detailing outcomes challenging. Objective To identify consensus on the key elements of academic detailing among a group of experts with varying experiences in academic detailing. Methods This study is based on an online survey of 20 experts with experience in academic detailing. We used the Delphi process, an iterative and systematic method of developing consensus within a group. We conducted 3 rounds of online surveys, which addressed 72 individual items derived from a previous literature review of 5 features of academic detailing, including (1) content, (2) communication process, (3) clinicians targeted, (4) change agents delivering intervention, and (5) context for intervention. Nonrespondents were removed from later rounds of the surveys. For most questions, a 4-point ordinal scale was used for responses. We defined consensus agreement as 70% of respondents for a single rating category or 80% for dichotomized ratings. Results The overall survey response rate was 95% (54 of 57 surveys) and nearly 92% consensus agreement on the survey items (66 of 72 items) by the end of the Delphi exercise. The experts' responses suggested that (1) focused clinician education offering support for clinical decision-making is a key component of academic detailing, (2) detailing messages need to be tailored and provide feasible strategies and solutions to challenging cases, and (3) academic detailers need

    In 1996 LEP ran at centre of mass energies of 161 and 172 GeV. An integrated luminosity of approx. 10 pb-1 was collected by the DELPHI experiment at each energy. These data are used to measure the cross-section for the doubly resonant WW process at these energies. At 161 GeV this cross-section may be interpreted, within the Standard Model, as a measurement of the W mass. The method of direct reconstruction is used to obtain a W mass using the 172 GeV data. Results on trilinear gauge couplings are also given.

    A methodology is outlined which can be used to estimate the costs of research and development projects. The approach uses the Delphi technique a method developed by the Rand Corporation for systematically eliciting and evaluating group judgments in an objective manner. The use of the Delphi allows for the integration of expert opinion into the cost-estimating process in a consistent and rigorous fashion. This approach can also signal potential cost-problem areas. This result can be a useful tool in planning additional cost analysis or in estimating contingency funds. A Monte Carlo approach is also examined.

    2006-08-01

    In this study the Delphi technique has been used to develop a core curriculum for education of the biomedical scientist. The rapid development in biomedicine and the corresponding changes in methodology in biomedical laboratories demand careful planning of the education of biomedical scientists. The Delphi technique uses an anonymous panel of experts for suggestions and assessments aiming at consensus. Twenty-six experts from different kinds of hospital and university laboratories took part in the investigation. They suggested and assessed necessary competences for a recently graduated biomedical scientist, and if 75% or more of the participants agreed on a competence, it was included in the core curriculum. The final list consisted of 66 competences of varying depth, in three categories. This list contained several generic competences, concerning for example basic laboratory methods, handling of samples, dealing with apparatus and applying relevant rules and laws; basic knowledge in chemistry, preclinical medicine and laboratory methods; and finally attitudes that the panel expected in the recently graduated person. The core was sufficiently restricted to be used in a three-year programme and still leave space for about one year of electives/special study modules. It became rather traditional, e.g. it did not include competences that many recent reports consider important for the future professional. PMID:16973452

    Climate change and non-communicable diseases (NCDs) are arguably the greatest global challenges of the 21st Century. However, the confluence between them remains under-examined and there is little evidence of a comprehensive, systematic approach to identifying research priorities to mitigate their joint impact. Consequently, we: (i) convened a workshop of academics (n = 25) from the Worldwide Universities Network to identify priority areas at the interface between NCDs and climate change; (ii) conducted a Delphi survey of international opinion leaders in public health and relevant other disciplines; and (iii) convened an expert panel to review and advise on final priorities. Three research areas (water security; transport; conceptualising NCD harms to support policy formation) were listed among the top 10 priorities by >90% of Delphi respondents, and ranked among the top 12 priorities by >60% of respondents who ranked the order of priority. A fourth area (reducing the carbon footprint of cities) was ranked highest by the same >60% of respondents. Our results are consistent with existing frameworks on health and climate change, and extends them by focusing specifically on NCDs. Researching these priorities could progress understanding of climate change and NCDs, and inform global and national policy decisions for mitigating associated harms. PMID:26501301

    Individualized acupuncture treatment has been practiced for pain therapy. This study used acupuncture treatment for lateral elbow pain (LEP) as an example to study the diagnostic practice of individualized acupuncture treatment. A provisional version of LEP pattern questionnaire was developed based on a recent systematic review on TCM pattern diagnosis for LEP. A Delphi panel of 33 clinical experts from seven different countries was formed, and the Delphi survey was conducted in Chinese and English language for two rounds. Consensus was achieved from all 26 panelists who responded to the second round on 243 items of the instrument, which included a 72-question-long questionnaire. The mean level of expert consensus on the items of the final questionnaire was 85%. Consensus was found on four TCM patterns that could underlie LEP, namely, the wind-cold-dampness pattern, the qi stagnation and blood stasis pattern, the dual deficiency of qi and blood pattern, and the retained dampness-heat pattern. A list of signs and symptoms indicating one of the four TCM patterns and a list of preferred treatment modalities for each pattern were also generated. Our instrument shows considerable content validity. Further validity and reliability studies are under way. PMID:27525024

    The purpose of this qualitative method study with a Delphi research design sought to determine how STEM programs can be effectively integrated into middle school career and technical education programs by local, state, and national educators, administrators, directors, specialists, and curriculum writers. The significance of the study is to provide leaders in CTE with a greater awareness, insight, and strategies about how CTE programs can more effectively integrate academics into career and technical education programs through STEM-related programming. The findings will increase the limited amount of available literature providing best practice strategies for the integration of STEM curriculum into middle school CTE programs. One basic question has guided this research: How can STEM programs be effectively integrated into middle school career and technical education programs? A total of twelve strategies were identified. The strategies of real-world applications and administrative buy-in were the two predominant strategies consistently addressed throughout the review of literature and all three sub-questions in the research study. The Delphi design study consisted of pilot round and three rounds of data collection on barriers, strategies, and professional development for STEM integration in middle school career and technical education programs. Four panelists participated in the pilot round, and 16 panel members not involved in the pilot round participated in the three rounds of questioning and consensus building. In the future, more comprehensive studies can build upon this foundational investigation of middle school CTE programs.

    Research with minors, especially for preventive purposes, e.g., suicide prevention, investigating risk or self-destructive behaviors such as deviance, drug abuse, or suicidal behavior, is ethically sensitive. We present a Delphi study exploring the ethical implications of the needs formulated by researchers in an international pre-conference who would benefit from ethics support and guidance in conducting Mental Health Research with minors. The resulting List of Ethical Issues (LEI) was submitted to a 2-rounds Delphi process via the Internet, including 34 multidisciplinary experts. In the first round, the experts reviewed the LEI and completed a questionnaire. Results from this round were analyzed and grouped in nine categories comprising 40 items. In the second round, the experts had to agree/disagree with the needs expressed in the LEI leading to a final list of 25 ethical issues considered relevant for Mental Health Research with minors such as: confidentiality of the sensitive data, competence for consenting alone and risk of harm and stigma related to the methodology used in research. It was shown that studies like SEYLE (Saving and Empowering Young Lives in Europe) trigger among researchers wishes to obtain specific recommendations helping to comply with standards for good practice in conducting research with minors.

    Background: Research on oral health contributes to improved health outcomes; it is an indispensable tool in health policy. But how to fill the gaps in research oral health and to strengthen its capacity is the question. The main objective of the present study is to identify the current status of oral health research and potential strategies, thereby strengthening the research infrastructure and capacity. Delphi consultation, in the perspective of assisting decision-makers to identify strategies to promote better research on oral health in Africa, was initiated. Design and Methods: The panels of 30 experts were asked to complete the questionnaire with 42 items into four groups by web survey. Each indicator statement was considered to be in consensus if the expert's opinion rating was of “A or B” for more than 75% in a scale of seven categories. Quantitative analysis was made from the answers of Delphi round. Results: There was a strong consensus about three items concerning the role of oral health research, the development of research policy for oral health going through an effective governance of research institutes, migration of researchers and fund raising. Conclusion: This study shows strong many dispersal opinions by experts, but highlights the need for to improve the effectiveness of oral health research capacity strengthening activities. Africa's researchers, policy makers and partners will have to give special attention to ensuring that knowledge generated from oral health research is acted on to improve health for all.

    Background Guidelines for how a member of the public should give first aid to a person who is becoming psychotic have been developed for English-speaking countries. However, these guidelines may not be appropriate for use in other cultures. A study was therefore carried out to examine whether it was possible to achieve consensus on guidelines that could apply in a range of Asian countries. Methods A Delphi consensus study was carried out with a panel of 28 Asian mental health clinicians drawn from Cambodia, China, Hong Kong, Indonesia, Japan, Malaysia, Mongolia, South Korea, Sri Lanka, Taiwan, Thailand and Vietnam. The panel was given a 211 item questionnaire about possible first aid actions and asked to rate whether they thought these should be included in guidelines. Panel members were invited to propose additional items. Results After three Delphi rounds, there were 128 items that were rated as "essential" or "important" by 80% or more of the panel members. These items covered: recognition of psychosis, encouraging and assisting the person to seek help, how to interact with the person, responding to acute psychosis, responding to aggression, and what to do if the person refuses to get professional help. Conclusion Despite the diversity of the countries involved, there was consensus on a core set of first aid items that were considered as suitable for assisting a psychotic person. Future work is needed to develop guidelines for specific countries. PMID:18291042

    This analysis reviews a selected body of research that identifies the essential areas of management expertise required of future health care executives. To ensure consistency, six studies are analyzed, utilizing the Delphi technique, to query a broad spectrum of experts in different fields and sites of health care management. The analysis identifies a number of management competencies, i.e., managerial capabilities, which current and aspiring health care executives, in various settings and with differing educational backgrounds, should possess to enhance the probability of their success in current and future positions of responsibility. In addition, this review identifies the skills (technical expertise), knowledge (facts and principles) and abilities (physical, mental or legal power) required to support achievement of these competencies. Leadership and resource management, including cost and finance dimensions, are the highest-rated requisite management competencies. The dominant skills, knowledge and abilities (SKAs) are related to interpersonal skills. The lowest-rated SKAs are related to job-specific, technical skills. Recommendations include the review of this research by formal and continuing education programs to determine the content of their courses and areas for future research. Similarly, current health care executives should assess this research to assist in identifying competency gaps. Lastly, this analysis recommends that the Delphi technique, as a valid and replicable methodology, be applied toward the study of non-executive health care managers, e.g., students, clinicians, mid-level managers and integrated systems administrators, to determine their requisite management competencies and SKAs.

    The aim of this Delphi-based study was to evaluate the intention of Spanish physicians to accept and use telemedicine as a future useful tool in daily practice. An online Delphi questionnaire was answered by 985 physicians (966 in the second round), representatives from rural and urban areas of the entire country (generalists, internists, cardiologists, endocrinologists, and nephrologists). The participants were 65% males, with a mean age of 46.7 years old and 20.3 years in the profession, mostly coming from primary care centers (91.8%) of urban Spanish areas (72.8%). Some responders (56.4%) reported lack of Internet use at work and 80.2% never participated in a telemedicine project, but 80.9% said they would be interested in participating in the future. As for the benefits of telemedicine, the specialties perceived as the most benefited were cardiology, followed by general medicine, pediatrics, and emergency services. The main reported difficulty for telemedicine implementation was the opinion that patients prefer the physical contact with physicians (77.8% of responders). Interviewed participants expressed strong interest in future telemedicine projects related to online training, distance control of chronic diseases, online communication among specialists, and real-time transmission of images and information. Most Spanish physicians have not implemented telemedicine in clinical practice, but they would be interested in future applications such as on-line training or disease control, although they still prefer physical patient contact.

    To address the uncertainty regarding future costs and operating attributes of electric and hybrid electric vehicles, a two stage, worldwide Delphi study was conducted. Expert opinions on vehicle attributes, current state of the technology, possible advancements, costs, and market penetration potential were sought for the years 2000, 2010, and 2020. Opinions related to such critical components as batteries, electric drive systems, and hybrid vehicle engines, as well as their respective technical and economic viabilities, were also obtained. This report contains descriptions of the survey methodology, analytical approach, and results of the analysis of survey data, together with a summary of other factors that will influence the degree of market success of electric and hybrid electric vehicle technologies. Responses by industry participants, the largest fraction among all the participating groups, are compared with the overall responses. An evaluation of changes between the two Delphi stages is also summarized. An analysis of battery replacement costs for various types is summarized, and variable operating costs for electric and hybrid vehicles are compared with those of conventional vehicles. A market penetration analysis is summarized, in which projected market shares from the survey are compared with predictions of shares on the basis of two market share projection models that use the cost and physical attributes provided by the survey. Finally, projections of market shares beyond the year 2020 are developed by use of constrained logit models of market shares, statistically fitted to the survey data.

    Highway traffic accidents all over the world result in more than 1.3 million fatalities annually. An alarming number of these fatalities occurs in developing countries. There are many risk factors that are associated with frequent accidents, heavy loss of lives, and property damage in developing countries. Unfortunately, poor record keeping practices are very difficult obstacle to overcome in striving to obtain a near accurate casualty and safety data. In light of the fact that there are numerous accident causes, any attempts to curb the escalating death and injury rates in developing countries must include the identification of the primary accident causes. This paper, therefore, seeks to show that the Delphi Technique is a suitable alternative method that can be exploited in generating highway traffic accident data through which the major accident causes can be identified. In order to authenticate the technique used, Korea, a country that underwent similar problems when it was in its early stages of development in addition to the availability of excellent highway safety records in its database, is chosen and utilized for this purpose. Validation of the methodology confirms the technique is suitable for application in developing countries. Furthermore, the Delphi Technique, in combination with the Bayesian Network Model, is utilized in modeling highway traffic accidents and forecasting accident rates in the countries of research.

    Climate change and non-communicable diseases (NCDs) are arguably the greatest global challenges of the 21st Century. However, the confluence between them remains under-examined and there is little evidence of a comprehensive, systematic approach to identifying research priorities to mitigate their joint impact. Consequently, we: (i) convened a workshop of academics (n = 25) from the Worldwide Universities Network to identify priority areas at the interface between NCDs and climate change; (ii) conducted a Delphi survey of international opinion leaders in public health and relevant other disciplines; and (iii) convened an expert panel to review and advise on final priorities. Three research areas (water security; transport; conceptualising NCD harms to support policy formation) were listed among the top 10 priorities by >90% of Delphi respondents, and ranked among the top 12 priorities by >60% of respondents who ranked the order of priority. A fourth area (reducing the carbon footprint of cities) was ranked highest by the same >60% of respondents. Our results are consistent with existing frameworks on health and climate change, and extends them by focusing specifically on NCDs. Researching these priorities could progress understanding of climate change and NCDs, and inform global and national policy decisions for mitigating associated harms. PMID:26501301

    Individualized acupuncture treatment has been practiced for pain therapy. This study used acupuncture treatment for lateral elbow pain (LEP) as an example to study the diagnostic practice of individualized acupuncture treatment. A provisional version of LEP pattern questionnaire was developed based on a recent systematic review on TCM pattern diagnosis for LEP. A Delphi panel of 33 clinical experts from seven different countries was formed, and the Delphi survey was conducted in Chinese and English language for two rounds. Consensus was achieved from all 26 panelists who responded to the second round on 243 items of the instrument, which included a 72-question-long questionnaire. The mean level of expert consensus on the items of the final questionnaire was 85%. Consensus was found on four TCM patterns that could underlie LEP, namely, the wind-cold-dampness pattern, the qi stagnation and blood stasis pattern, the dual deficiency of qi and blood pattern, and the retained dampness-heat pattern. A list of signs and symptoms indicating one of the four TCM patterns and a list of preferred treatment modalities for each pattern were also generated. Our instrument shows considerable content validity. Further validity and reliability studies are under way. PMID:27525024

    Research with minors, especially for preventive purposes, e.g., suicide prevention, investigating risk or self-destructive behaviors such as deviance, drug abuse, or suicidal behavior, is ethically sensitive. We present a Delphi study exploring the ethical implications of the needs formulated by researchers in an international pre-conference who would benefit from ethics support and guidance in conducting Mental Health Research with minors. The resulting List of Ethical Issues (LEI) was submitted to a 2-rounds Delphi process via the Internet, including 34 multidisciplinary experts. In the first round, the experts reviewed the LEI and completed a questionnaire. Results from this round were analyzed and grouped in nine categories comprising 40 items. In the second round, the experts had to agree/disagree with the needs expressed in the LEI leading to a final list of 25 ethical issues considered relevant for Mental Health Research with minors such as: confidentiality of the sensitive data, competence for consenting alone and risk of harm and stigma related to the methodology used in research. It was shown that studies like SEYLE (Saving and Empowering Young Lives in Europe) trigger among researchers wishes to obtain specific recommendations helping to comply with standards for good practice in conducting research with minors.

    Introduction: After a devastating earthquake, the site selection for the sheltering of earthquake victims is an important task. In order to generate a list of appropriate criteria for deciding on temporary sheltering site selection, we systematically combined the experience of experts and the findings of published documents in this study. Methods: Having explored published papers, we generated a list of criteria for the selection of the best location for temporary sheltering. In the next step, all criteria were presented to a group of experts in Iran and after a scientific discussion, the list was updated. In the last step, the final list of criteria was developed using the Delphi method in three rounds. Results: Based on our previous systematic review, 27 criteria were presented for sheltering site selection. Expert interviews added 12 more items to them. The Delphi process approved 21 criteria of all proposed ones. These items then grouped into four categories: land suitability, socio-cultural considerations, service availability and disaster risk reduction. Discussion: After an earthquake, our list of criteria may help the disaster team to select the best locations for temporary sheltering with minimum confusion. The consent of the earthquake victims and cost reduction of the operation would be the minimum benefits of using the appropriate criteria. These criteria also could be used by researchers to make objective and reproducible assessments of temporary sheltering site selection. Key words: Criteria, Earthquake, Model, Site selection, Temporary shelter, PMID:26693079

    Abstract Background: “Chemical coping” is a commonly used term in the pain and palliative care literature, but is heterogeneously defined. We conducted a Delphi survey among palliative care and pain specialists internationally to identify a consensus definition for “chemical coping with opioids” and warning signs for chemical coping. Methods: This Delphi survey consisted of two rounds on the following: (1) concepts and definition related to chemical coping, (2) warning signs for chemical coping, and (3) demographics. Consensus in this study was defined as agreement by a minimum of 70% of the experts. Results: Participating in the first round were 14/19 (74%) physicians; 12/14 (86%) participated in the second round. The international experts reached the following consensus definition for chemical coping with opioids (92% agreement): “The use of opioids to cope with emotional distress, characterized by inappropriate and/or excessive opioid use.” They also identified depression (consensus 93%); psychiatric disease (86%); a history of substance abuse (86%); a positive score for the Cut-down, Annoyed, Guilty, and Eye-opener (CAGE) alcoholism screening test (79%); a history of alcoholism (79%); and a history of smoking (71%) as important warning signs for chemical coping. Conclusion: Our expert panel reached a consensus definition for chemical coping and related warning signs, which may help clinicians and researchers to identify patients at risk of opioid misuse.

    The aim of this study was to identify current trends in clinical assessment and management of stress velopharyngeal insufficiency (VPI) in wind musicians. This was an online two-round Delphi survey of health practitioners familiar with assessing and treating musicians with stress VPI. Fourteen specialists (seven otolaryngologists and seven speech-language pathologists) from four countries participated in the Delphi survey. From the first round questionnaire, 32 items were identified as being causes, assessment tools, diagnostic indicators, and treatment methods for stress VPI. The second round questionnaire revealed that prolonged exposure to high intra-oral pressures was important in determining the cause of stress VPI. The most important assessment tools for stress VPI were case history and nasendoscopy. The most important indicator for stress VPI was self-reported symptoms. There was no clear agreement identified on the management methods for stress VPI for musicians. However, the trend followed by most of the survey participants was a combination of conservative management approaches (including rest or watch and wait, speech-language pathology intervention, velopharyngeal muscle training, and changes to the instrument or reed), and then, if symptoms persist, to use injection pharyngoplasty or pharyngeal flap. This survey demonstrates that no standard management protocol currently exists for musicians diagnosed with stress VPI, but provides current trends in the assessment and management which can be used in future guidelines for health professionals who treat wind musicians.

    Objective For children aged 1–5 years, the authors used the Delphi method to determine (1) the most important injury hazards in each area of the home; (2) the most important injury prevention behaviors; and (3) feasible and efficacious safety devices and behaviors to reduce injury risks. Design The authors used a modified Delphi method to prioritize home injury hazards for children 1–5 years of age. The Delphi method is an indirect, anonymous, iterative process aimed at achieving consensus among experts; in this study, the authors queried key informants electronically. Thirty four key informants, primarily from the United States, participated in at least one of the three rounds of questionnaires. Responses were submitted by email or fax. Participants identified, rated, and ranked home injury hazards and prevention methods. Results The overall response rate for each survey ranged from 82% to 97%. Initially, 330 unique hazards and prevention behaviors/devices were identified in seven areas of the home. The 126 home injury hazards were rated based on frequency, severity, and preventability of injury; and the 204 behaviors and devices were rated by efficacy and feasibility. These experts rated firearms and pools as the most significant hazards, and smoke alarms and safe water temperature as the most important preventions. Conclusions The modified Delphi method of consensus was useful to prioritize home injury hazards and prevention methods for children under the age of 6 years. PMID:16751451

    The Delphi technique is a means of facilitating discussion among experts in order to develop consensus, and can be used for policy formulation. This article describes a modified Delphi approach in which 27 multi-disciplinary academics and 22 stakeholders from Ghana and North America were polled about ways to address negative effects of small-scale gold mining (ASGM) in Ghana. In early 2014, the academics, working in disciplinary groups, synthesized 17 response options based on data aggregated during an Integrated Assessment of ASGM in Ghana. The researchers participated in two rounds of Delphi polling in March and April 2014, during which 17 options were condensed into 12. Response options were rated via a 4-point Likert scale in terms of benefit (economic, environmental, and benefit to people) and feasibility (economic, social/cultural, political, and implementation). The six highest-scoring options populated a third Delphi poll, which 22 stakeholders from diverse sectors completed in April 2015. The academics and stakeholders also prioritized the response options using ranking exercises. The technique successfully gauged expert opinion on ASGM, and helped identify potential responses, policies and solutions for the sector. This is timely given that improvement to the ASGM sector is an important component within the UN Minamata Convention. PMID:26378557

    Background Neonatal trials remain difficult to conduct for several reasons: in particular the need for study sites to have an existing infrastructure in place, with trained investigators and validated quality procedures to ensure good clinical, laboratory practices and a respect for high ethical standards. The objective of this work was to identify the major criteria considered necessary for selecting neonatal intensive care units that are able to perform drug evaluations competently. Methodology and Main Findings This Delphi process was conducted with an international multidisciplinary panel of 25 experts from 13 countries, selected to be part of two committees (a scientific committee and an expert committee), in order to validate criteria required to perform drug evaluation in neonates. Eighty six items were initially selected and classified under 7 headings: “NICUs description - Level of care” (21), “Ability to perform drug trials: NICU organization and processes (15), “Research Experience” (12), “Scientific competencies and area of expertise” (8), “Quality Management” (16), “Training and educational capacity” (8) and “Public involvement” (6). Sixty-one items were retained and headings were rearranged after the first round, 34 were selected after the second round. A third round was required to validate 13 additional items. The final set includes 47 items divided under 5 headings. Conclusion A set of 47 relevant criteria will help to NICUs that want to implement, conduct or participate in drug trials within a neonatal network identify important issues to be aware of. Summary Points 1) Neonatal trials remain difficult to conduct for several reasons: in particular the need for study sites to have an existing infrastructure in place, with trained investigators and validated quality procedures to ensure good clinical, laboratory practices and a respect for high ethical standards. 2) The present Delphi study was conducted with an

    Background Adverse drug events are a major cause of patient safety incidents. Current systems of pharmacovigilance under-report adverse drug reactions (ADRs), especially in children, leading to delays in their identification. This is of particular concern, as children especially have an increased vulnerability to ADRs. Objectives The objective was to seek consensus among healthcare professionals (HCPs) about barriers and facilitators to the linkage of routinely collected health data for pediatric pharmacovigilance in Scotland. Methods A Delphi survey was conducted with a random sample of HCPs including nurses, pharmacists and doctors, working in primary or secondary care, in Scotland. Participants were identified from sampling frames of the target professionals such as an NHS workforce list for general practitioners and recruited by postal invitation. A total of 819 HCPs were invited to take part. Those agreeing to participate were given the option of completing the questionnaires online or as hard copy. Reminders were sent twice at a fortnightly interval. Questions content included description of professional role as well as testing for the willingness to support the proposed project and was informed by the Theoretical Domains Framework of Behavior Change (TDF) and earlier qualitative work. Three Delphi rounds were administered, including a first round for item generation. Results 121 of those invited agreed to take part (15%). The first round of the Delphi study included 21 open questions and generated over a 1000 individual statements from 61 participants that returned the questionnaires (50.4%). These were rationalized to 149 items for the second round in which participants rated their views on the importance (or not) of each item on a 9-point Likert scale (strongly disagree – strongly agree). After the third round, there was consensus on items that focused on professional standards, and practical requirements, overall there was support for data linkage and a

    Correctional nursing has been recognized as a specialty since 1985, but research to describe and support nursing practice in the criminal justice system has been sparse. The development of a research agenda can stimulate the research necessary to provide an evidence base for specialty practice development. A three-round Delphi study was undertaken to elicit a prioritized list of research topics to guide future research efforts for meaningful results. Six predominant themes emerged from an analysis of top research questions generated by a panel of 18 correctional nursing experts. Research priorities include critical thinking and clinical judgment, competency and educational level, assessment, nursing protocols, effect on patient outcomes, and the environment of care.

    The need to train non-sleep-specialist health professionals in evidence-based pediatric behavioral sleep care is well established. The objective of the present study was to develop a list of core competencies for training health professionals in assisting families of 1- to 10-year old children with behavioral insomnia of childhood. A modified Delphi methodology was employed, involving iterative rounds of surveys that were administered to 46 experts to obtain consensus on a core competency list. The final list captured areas relevant to the identification and treatment of pediatric behavioral sleep problems. This work has the potential to contribute to the development of training materials to prepare non-sleep-specialist health professionals to identify and treat pediatric behavioral sleep problems, ideally within stepped-care frameworks.

    Stocks evaluation has always been an interesting and challenging problem for both researchers and practitioners. Generally, the evaluation can be made based on a set of financial ratios. Nevertheless, there are a variety of financial ratios that can be considered and if all ratios in the set are placed into the evaluation process, data collection would be more difficult and time consuming. Thus, the objective of this paper is to identify the most important financial ratios upon which to focus in order to evaluate the stock's performance. For this purpose, a survey was carried out using an approach which is based on an expert judgement, namely the Fuzzy Delphi Method (FDM). The results of this study indicated that return on equity, return on assets, net profit margin, operating profit margin, earnings per share and debt to equity are the most important ratios.

    Project evaluation and selection is a factor affecting the impotence of board director in which is trying to maximize all the possible goals. Assessment of the problem occurred in organization plan is the first phase for decision making process. The company needs a group of expert to evaluate the problems. The Fuzzy Delphi Method (FDM) is a systematic procedure to evoke the group's opinion in order to get the best result to evaluate the project performance. This paper proposes an evaluation and selection of the best alternative project based on combination of FDM and Zero - One Goal Programming (ZOGP) formulation. ZOGP is used to solve the multi-criteria decision making for final decision part by using optimization software LINDO 6.1. An empirical example on an ongoing decision making project in Johor, Malaysia is implemented for case study.

    This study aims to develop a new procedure that combines multi-criteria spatial vulnerability analysis with the traditional linear probabilistic risk approach. This approach is named integrated fuzzy flood vulnerability assessment because it combines the watershed-based vulnerability framework with stream-based risk analysis. The Delphi technique and pressure-state-impact-response framework are introduced to objectively select evaluation criteria, and the fuzzy TOPSIS technique is proposed to address the uncertainty of weights to all criteria and crisp input data of all spatial units. ArcGIS is used to represent the spatial results to all criteria. This framework is applied to the south Han River basin in South Korea. As a result, the flood vulnerability ranking was derived and vulnerability characteristics of all spatial units were compared. This framework can be used to conduct a prefeasibility study for flood mitigation projects when various stakeholders should be included.

    Single photons detected by the DELPHI experiment at LEP2 in the years 1997-2000 are reanalysed to investigate the existence of a single extra dimension in a modified ADD scenario with slightly warped large extra dimensions. The data collected at centre-of-mass energies between 180 and 209 GeV for an integrated luminosity of ˜650 pb-1 agree with the predictions of the Standard Model and allow a limit to be set on graviton emission in one large extra dimension. The limit obtained on the fundamental mass scale M D is 1.69 TeV/ c 2 at 95% CL, with an expected limit of 1.71 TeV/ c 2.

    2013-01-01

    Background Human papillomavirus is the most significant factor contributing to cervical cancer. Naturopathic doctors (NDs) implement an integrative approach to treat cervical atypia. This study explored practice consensus and variance among NDs. Methods A purposefully selected panel of six NDs participated in a modified Delphi study to validate practice. Three electronic web-based surveys were completed over nine months. Results Local and systemic treatments were included in all ND protocols. Six protocols included cervical cancer screening guidelines, green tea suppositories, and oral folic acid. Five protocols included oral green tea, diindoylemethane (DIM), and cartenoids. Four protocols incorporated Vitamin C. Two NDs considered escharotics when managing cervical atypia. All NDs included health behavior management in their protocols. Conclusion Naturopathic management of cervical atypia varies across practitioners. However, in general, elements of management include (1) cervical cancer screening guidelines, (2) local and systemic treatments, (3) health behavior/lifestyle recommendations, and (4) immune system support.

    There is a need in The Netherlands to understand the future prospects of imaging techniques in cancer care to deal with current and expected capacity decisions. For this, a Delphi research was performed with a panel of 35 noted experts. The panel anticipates that the application of imaging techniques (e.g., CT, MRI, PET) will gradually change; especially, their use will also include earlier stages, i.e., cancer screening and treatment. The increasing need and investments for these techniques will be partly balanced by new developments (e.g., faster technology). There will be a substantial decrease in the use of ultrasound, CT (except for screening), and conventional radiographic diagnostics. Radical new techniques and/or developments are not expected. The panel foresees increasing partial task substitution and subspecialization. Further, a profound impact on imaging techniques is expected from developments outside the imaging field such as digitalization, changing patient demands, and commercialization. PMID:16691374

    Complex software for shower reconstruction in DELPHI barrel electromagnetic calorimeter which deals, for each event, with great amounts of information, due to the high spatial resolution of this detector, needs powerful verification tools. An interactive graphics program, running on high performance graphics display system Whizzard 7555 from Megatek, was developed to display the logical steps in showers and their axes reconstruction. The program allows both operations on the image in real-time (rotation, translation and zoom) and the use of non-geometrical criteria to modify it (as the use of energy) thresholds for the representation of the elements that compound the showers (or of the associated lego plots). For this purpose graphics objects associated to user parameters were defined. Instancing and modelling features of the native graphics library were extensively used.

    2014-01-01

    Background After the 2011 cluster of Hendra virus cases in horses in Australia, public health targeted education initiatives at people in the equine industry to reduce human exposure to potentially infected horses. ‘Horse owners and Hendra Virus: A Longitudinal cohort study To Evaluate Risk’ aims to enhance public health measures through improved understanding of Hendra virus risk perception and risk mitigation strategies among horse owners and horse care providers. This paper describes the stakeholder consultation that was undertaken to ensure the cohort study outcomes were relevant to diverse groups who play a role in Hendra virus policy development and implementation. Methods A two-round modified Delphi study with online questionnaires was conducted. In round one, stakeholders identified priority research areas. In round two, stakeholders rated and ranked topics that emerged from thematic analysis of the round one responses. Round two data were analysed using logistic regression. Results Of the 255 stakeholders contacted, 101 responded to round one. Over 450 topics were proposed. These were organized into 18 themes. Approximately two thirds of the round one respondents participated in round two. ‘Hendra virus-related risk awareness and perception’, ‘personal health and safety’, ‘emergency preparedness’, ‘risk prevention, mitigation, and biosecurity’, and ‘Hendra virus vaccination in horses – attitudes/uptake’ were the top five areas identified according to probability of being ranked extremely important. Conclusions In this study, a modified Delphi approach was effective in guiding research into Hendra virus, a zoonotic disease of animal and human health significance. The findings support the notion that stakeholders should be engaged in zoonotic disease research priority setting. Such consultation will help to ensure that research initiatives are relevant and useful to stakeholders in the position to make use of new findings. PMID

    Objectives A large number of Canadians spend time in correctional facilities each year, and they are likely to have poor health compared to the general population. Relatively little health research has been conducted in Canada with a focus on people who experience detention or incarceration. We aimed to conduct a Delphi process with key stakeholders to define priorities for research in prison health in Canada for the next 10 years. Setting We conducted a Delphi process using an online survey with two rounds in 2014 and 2015. Participants We invited key stakeholders in prison health research in Canada to participate, which we defined as persons who had published research on prison health in Canada since 1994 and persons in the investigators’ professional networks. We invited 143 persons to participate in the first round and 59 participated. We invited 137 persons to participate in the second round and 67 participated. Primary and secondary outcome measures Participants suggested topics in the first round, and these topics were collated by investigators. We measured the level of agreement among participants that each collated topic was a priority for prison health research in Canada for the next 10 years, and defined priorities based on the level of agreement. Results In the first round, participants suggested 71 topics. In the second round, consensus was achieved that a large number of suggested topics were research priorities. Top priorities were diversion and alternatives to incarceration, social and community re-integration, creating healthy environments in prisons, healthcare in custody, continuity of healthcare, substance use disorders and the health of Aboriginal persons in custody. Conclusions Generated in an inclusive and systematic process, these findings should inform future research efforts to improve the health and healthcare of people who experience detention and incarceration in Canada.

  16. Mental Health First Aid guidelines for helping a suicidal person: a Delphi consensus study in India

    PubMed Central

    2010-01-01

    Background This study aimed to develop guidelines for how a member of the Indian public should provide mental health first aid to a person who is suicidal. Methods The guidelines were produced by developing a questionnaire containing possible first aid actions and asking an expert panel of Indian mental health clinicians to rate whether each action should be included in the guidelines. The content of the questionnaire was based on a systematic search of the relevant evidence and claims made by authors of consumer and carer guides and websites. Experts were recruited by SC, EC and HM. The panel members were asked to complete the questionnaire by web survey. Three rounds of the rating were carried and, at the end of each round, items that reached the consensus criterion were selected for inclusion in the guidelines. During the first round, panel members were also asked to suggest any additional actions that were not covered in the original questionnaire (to include items that are relevant to local cultural circumstances, values, and social norms.). Responses to the open-ended questions were used to generate new items. Results The output from the Delphi process was a set of agreed upon action statements. The Delphi process started with 138 statements, 30 new items were written based on suggestions from panel members and, of these 168 items, 71 met the consensus criterion. These statements were used to develop the guidelines appended to this paper. Translated versions of the guidelines will be produced and used for training. Conclusions There are a number of actions that are considered to be useful for members of the public when they encounter someone who is experiencing suicidal thoughts or engaging in suicidal behaviour. Although the guidelines are designed for members of the public, they may also be helpful to non-mental health professionals working in health and welfare settings. PMID:20167125

    Background This study aimed to develop guidelines for how a member of the Japanese public should provide mental health first aid to a person who is suicidal. Methods The guidelines were produced by developing a questionnaire containing possible first aid actions and asking an expert panel of 32 Japanese mental health professionals to rate whether each action should be included in the guidelines. The content of the questionnaire was based on a systematic search of the relevant evidence and claims made by authors of consumer and carer guides and websites. The panel members were asked to complete the questionnaire by web survey. Three rounds of the rating were carried and, at the end of each round, items that reached the consensus criterion were selected for inclusion in the guidelines. During the first round, panel members were also asked to suggest any additional actions that were not covered in the original questionnaire (to include items that are relevant to local cultural circumstances, values, and social norms). Responses to these open-ended questions were used to generate new items. Results The output from the Delphi process was a set of agreed upon action statements. The Delphi process started with 138 statements, 38 new items were written based on suggestions from panel members and, of these 176 items, 56 met the consensus criterion. These statements were used to develop the guidelines appended to this article. Conclusions There are a number of actions that are considered to be useful for members of the Japanese public when they encounter someone who is experiencing suicidal thoughts or engaging in suicidal behaviour. Although the guidelines are designed for members of the public, they may also be helpful to health professionals working in health and welfare settings who do not have clinical mental health training.

    2014-01-01

    Four chemotypes of the Rough lipopolysaccharides (LPS) membrane from Pseudomonas aeruginosa were investigated by a combined approach of explicit water molecular dynamics (MD) simulations and Poisson-Boltzmann continuum electrostatics with the goal to deliver the distribution of the electrostatic potential across the membrane. For the purpose of this investigation, a new tool for modeling the electrostatic potential profile along the axis normal to the membrane, MEMPOT, was developed and implemented in DelPhi. Applying MEMPOT on the snapshots obtained by MD simulations, two observations were made: (a) the average electrostatic potential has a complex profile, but is mostly positive inside the membrane due to the presence of Ca2+ ions which overcompensate for the negative potential created by lipid phosphate groups; and (b) correct modeling of the electrostatic potential profile across the membrane requires taking into account the water phase, while neglecting it (vacuum calculations) results in dramatic changes including a reversal of the sign of the potential inside the membrane. Furthermore, using DelPhi to assign different dielectric constants for different regions of the LPS membranes, it was investigated whether a single frame structure before MD simulations with appropriate dielectric constants for the lipid tails, inner, and the external leaflet regions, can deliver the same average electrostatic potential distribution as obtained from the MD-generated ensemble of structures. Indeed, this can be attained by using smaller dielectric constant for the tail and inner leaflet regions (mostly hydrophobic) than for the external leaflet region (hydrophilic) and the optimal dielectric constant values are chemotype-specific.

    Objective Hip pain and injury as a result of activity can lead to the development of early hip osteoarthritis (OA) in susceptible individuals. Our understanding of the factors that increase susceptibility continues to evolve. The ability to clearly identify individuals (and cohorts) with activity-related hip pain who are at risk of early hip OA is currently lacking. The purpose of this study was to gain expert consensus on which key clinical measures might help predict the risk of early hip OA in individuals presenting with activity-related hip pain. The agreed measures would constitute a standardised approach to initial clinical assessment to help identify these individuals. Methods This Dephi study used online surveys to gain concordance of expert opinion in a structured process of ‘rounds’. In this study, we asked ‘What outcome measures are useful in predicting hip OA in activity-related hip pain?’ The Delphi panel consisted of experts from sport and exercise medicine, orthopaedics, rheumatology, physiotherapy and OA research. Results The study identified key clinical measures in the history, examination and investigations (plain anteroposterior radiograph and femoroacetabular impingement views) that the panel agreed would be useful in predicting future risk of hip OA when assessing activity-related hip pain. The panel also agreed that certain investigations and tests (eg, MR angiography) did not currently have a role in routine assessment. There was a lack of consensus regarding the role of MRI, patient-reported outcome measures (PROMs) and certain biomechanical and functional assessments. Conclusions We provide a standardised approach to the clinical assessment of patients with activity-related hip pain. Assessment measures rejected by the Delphi panel were newer, more expensive investigations that currently lack evidence. Assessment measures that did not reach consensus include MRI and PROMs. Their role remains ambiguous and would benefit from further

    Background: Anatomically shaped, form-stable Natrelle 410 breast implants were approved in Europe in 1993 and in the United States in 2013. Although general guidelines for breast augmentation are available, the distinctive characteristics of Natrelle 410 warrant specific guidelines for this device. The goal of this study was to generate consensus recommendations for intraoperative technique and postoperative management with Natrelle 410 in primary breast augmentation. Methods: Surgeons were invited to participate in the study, which used a modified Delphi method. Participants completed 2 rounds of online surveys; the second survey (Recommendations Survey) was generated based on first survey results. Respondents also listed top priorities for use of Natrelle 410. Results: Participants (n = 22) reached consensus on 15 of 18 perioperative and surgical techniques; dual-plane placement, tight pockets, and limiting the boundaries of dissection were among intraoperative techniques considered most important for Natrelle 410. Consensus was reached for 18 of 32 items regarding postoperative management and 6 of 9 open-ended postoperative activity restrictions. Consensus on activity restrictions with specified time limits were similar to consensus recommendations on general restrictions. Top participant-identified intraoperative and postoperative management practices for Natrelle 410 were dual-plane placement of the implant and wearing a bra postoperatively, respectively. Conclusions: The Delphi method identified consensus recommendations on a broad range of intraoperative techniques and postoperative management practices for primary breast augmentation with Natrelle 410. These recommendations and priorities provide surgeons with a framework that, together with the surgeon’s experience, will contribute to optimal clinical outcomes with Natrelle 410. PMID:26893982

    Although there are high survival rates for children with acute lymphoblastic leukaemia, their outcome is often counterbalanced by the burden of toxic effects. This is because reported frequencies vary widely across studies, partly because of diverse definitions of toxic effects. Using the Delphi method, 15 international childhood acute lymphoblastic leukaemia study groups assessed acute lymphoblastic leukaemia protocols to address toxic effects that were to be considered by the Ponte di Legno working group. 14 acute toxic effects (hypersensitivity to asparaginase, hyperlipidaemia, osteonecrosis, asparaginase-associated pancreatitis, arterial hypertension, posterior reversible encephalopathy syndrome, seizures, depressed level of consciousness, methotrexate-related stroke-like syndrome, peripheral neuropathy, high-dose methotrexate-related nephrotoxicity, sinusoidal obstructive syndrome, thromboembolism, and Pneumocystis jirovecii pneumonia) that are serious but too rare to be addressed comprehensively within any single group, or are deemed to need consensus definitions for reliable incidence comparisons, were selected for assessment. Our results showed that none of the protocols addressed all 14 toxic effects, that no two protocols shared identical definitions of all toxic effects, and that no toxic effect definition was shared by all protocols. Using the Delphi method over three face-to-face plenary meetings, consensus definitions were obtained for all 14 toxic effects. In the overall assessment of outcome of acute lymphoblastic leukaemia treatment, these expert opinion-based definitions will allow reliable comparisons of frequencies and severities of acute toxic effects across treatment protocols, and facilitate international research on cause, guidelines for treatment adaptation, preventive strategies, and development of consensus algorithms for reporting on acute lymphoblastic leukaemia treatment.

    Background Facilitating motor learning in patients during clinical practice is complex, especially in people with cognitive impairments. General principles of motor learning are available for therapists to use in their practice. However, the translation of evidence from the different fields of motor learning for use in clinical practice is problematic due to lack of uniformity in definition and taxonomy of terms related to motor learning. Objective The objective of this paper was to describe the design of a Delphi technique to reach consensus on definitions, descriptions, and taxonomy used within motor learning and to explore experts’ opinions and experiences on the application of motor learning in practice. Methods A heterogeneous sample of at least 30 international experts on motor learning will be recruited. Their opinions regarding several central topics on motor learning using a Delphi technique will be collected in 3 sequential rounds. The questionnaires in the 3 rounds will be developed based on the literature and answers of experts from earlier rounds. Consensus will be reached when at least 70% of the experts agree on a certain topic. Free text comments and answers from open questions on opinions and experiences will be described and clustered into themes. Results This study is currently ongoing. It is financially supported by Stichting Alliantie Innovatie (Innovation Alliance Foundation), RAAK-international (Registration number: 2011-3-33int). Conclusions The results of this study will enable us to summarize and categorize expert knowledge and experiences in a format that should be more accessible for therapists to use in support of their clinical practice. Unresolved aspects will direct future research. PMID:23685621

    There is little known about private practice nursing as an area of advanced practice. As more nurses take the option to develop private practice, the experiences of and influences on nurses currently in private practice might be a useful guide to the pitfalls and difficulties which might be encountered. In addition, an understanding of the experiences of and influences might assist nursing organizations and health services to provide support to nurses who play an integral part in health care delivery in the community. A research study was undertaken utilizing a two-round Delphi Technique to elicit and assess consensus on the reasons for nurses going into business and the experiences they encountered in becoming and being a nurse entrepreneur. The study instrument in round one comprised a questionnaire with statement headings inviting opinions on the influences and experiences of nurses in business. In the second round, levels of agreement were elicited from responders on collated opinions from round one, including statements formed from comments written in round one. The initial questionnaire also included closed questions to obtain a profile of nurses in private practice. Responders were 59 nurses in private practice in round one and 54 nurses in round two. The themes raised could be grouped under headings of influences, advantages/disadvantages, education/experience, skills/knowledge, characteristics and barriers. The level of agreement on the themes was reasonably high. Dissent occurred on issues of increased income, professional image and support structures. This Delphi study has identified key areas of consensus on the experiences of nurses in private practice who have extended their career into the business arena. It has also identified areas in which further work needs to be carried out to understand this work of nurse entrepreneurs. PMID:12887375

    Nanoscale science and technology (NST) is an important new field in modern science. In the current study, we seek to answer the question: 'What are the essential concepts of NST that should be taught in high school'? A 3-round Delphi study methodology was applied based on 2 communities of experts in nanotechnology research and science education. Eight essential concepts in NST were identified. Each concept is accompanied by its explanation, definition, importance and includes subcategories that compose it. Three concepts emerged in the Delphi study, which were not identified before: functionality, classification of nanomaterials, and the making of nanotechnology. Differences between the concepts suggested by the 2 communities of experts were found. The results of this study serve as a tool to examine different nanotechnology programs that were reported thus far and to make recommendations for designing a NST program for high school students that includes the essential concepts.

    Historical data are fundamental to the understanding of the seismic history of an area. At the same time, knowledge of the active tectonic processes allows us to understand how earthquakes have been perceived by past cultures. Delphi is one of the principal archaeological sites of Greece, the main oracle of Apollo. It was by far the most venerated oracle of the Greek ancient world. According to tradition, the mantic proprieties of the oracle were obtained from an open chasm in the earth. Delphi is directly above one of the main antithetic active faults of the Gulf of Corinth Rift, which bounds Mount Parnassus to the south. The geometry of the fault and slip-parallel lineations on the main fault plane indicate normal movement, with minor right-lateral slip component. Combining tectonic data, archaeological evidence, historical sources, and a reexamination of myths, it appears that the Helice earthquake of 373 B.C. ruptured not only the master fault of the Gulf of Corinth Rift at Helice, but also the antithetic fault at Delphi, similarly to the Corinth earthquake of 1981. Moreover, the presence of an active fault directly below the temples of the oldest sanctuary suggests that the mythological oracular chasm might well have been an ancient tectonic surface rupture.

    This study aimed to develop effectiveness indicators for social marketing communication to reduce health-risk behaviors among Thai youth by using the Delphi technique. The Delphi technique is a research approach used to gain consensus through a series of two or more rounds of questionnaire surveys where information and results are fed back to panel members between each round and it has been extensively used to generate many indicators relevant to health behaviors. The Delphi technique was conducted in 3 rounds by consulting a panel of 15 experts in the field of social marketing communication for public health campaigns in Thailand. We found forty-nine effectiveness indicators in eight core components reached consensus. These components were: 1) attitude about health-risk behavior reduction, 2) subjective norms, 3) perceived behavioral control, 4) intention to reduce health-risk behaviors, 5) practices for reducing health-risk behaviors, 6) knowledge about the dangers and impact of health-risk behaviors, 7) campaign brand equity, and 8) communication networks. These effectiveness indicators could be applied by health promotion organizations for evaluating the effectiveness of social marketing communication to effectively reduce health-risk behaviors among youth.

    Persistent gaps in the evidence base regarding the performance of conservation policies has put pressure on the conservation policy field to adopt 'best practice' programme evaluation methods. These are methods that account for the counterfactual and are able to attribute causality between a conservation policy and specific observable environmental and social impacts. Despite this pressure, use of such methods continues to be rare. This paper uses the Delphi technique to provide the first systematic assessment of the reasons behind the apparent hesitation of conservation practitioners to adopt rigorous policy impact evaluation methods. The Delphi study consisted of two online questionnaires conducted on conservation policy experts. The results presented confirm that the use of rigorous impact evaluation methods in conservation is still very limited but this, crucially, is not because conservationists are ignorant of these methods or their advantages. In fact, considerable effort is being made to develop and improve evidence standards but these efforts have largely been thwarted by large financial and time related constraints that mean even elementary evaluations are hard to achieve. The results from this Delphi study allow us to provide more realistic recommendations on how impact evaluation studies can be more widely embraced and implemented in conservation practice.

    2012-01-01

    Background The mental health community in Japan had started reviewing the country’s disaster mental health guidelines before the Great East Japan Earthquake, aiming to revise them based on evidence and experience accumulated in the last decade. Given the wealth of experience and knowledge acquired in the field by many Japanese mental health professionals, we decided to develop the guidelines through systematic consensus building and selected the Delphi method. Methods After a thorough literature review and focus group interviews, 96 items regarding disaster mental health were included in Delphi Round 1. Of 100 mental health professionals experienced in disaster response who were invited to participate, 97 agreed. The appropriateness of each statement was assessed by the participants using a Likert scale (1: extremely inappropriate, 9: very appropriate) and providing free comments in three rounds. Consensus by experts was defined as an average score of ≥7 for which ≥70% of participants assigned this score, and items reaching consensus were included in the final guidelines. Results Overall, of the 96 items (89 initially asked and 7 added items), 77 items were agreed on (46 items in Round 1, and 19 positive and 12 negative agreed on items in Round 2). In Round 2, three statements with which participants agreed most strongly were: 1) A protocol for emergency work structure and information flow should be prepared in normal times; 2) The mental health team should attend regular meetings on health and medicine to exchange information; and 3) Generally, it is recommended not to ask disaster survivors about psychological problems at the initial response but ask about their present worries and physical condition. Three statements with which the participants disagreed most strongly in this round were: 1) Individuals should be encouraged to provide detailed accounts of their experiences; 2) Individuals should be provided with education if they are interested in receiving

    2011-01-01

    Background Comprehensive, multi-level approaches are required to address obesity. One important target for intervention is the economic domain. The purpose of this study was to synthesize existing evidence regarding the impact of economic policies targeting obesity and its causal behaviours (diet, physical activity), and to make specific recommendations for the Canadian context. Methods Arksey and O'Malley's (2005) methodological framework for conducting scoping reviews was adopted for this study and this consisted of two phases: 1) a structured literature search and review, and 2) consultation with experts in the research field through a Delphi survey and an in-person expert panel meeting in April 2010. Results Two key findings from the scoping review included 1) consistent evidence that weight outcomes are responsive to food and beverage prices. The debate on the use of food taxes and subsidies to address obesity should now shift to how best to address practical issues in designing such policies; and 2) very few studies have examined the impact of economic instruments to promote physical activity and clear policy recommendations cannot be made at this time. Delphi survey findings emphasised the relatively modest impact any specific economic instrument would have on obesity independently. Based on empirical evidence and expert opinion, three recommendations were supported. First, to create and implement an effective health filter to review new and current agricultural polices to reduce the possibility that such policies have a deleterious impact on population rates of obesity. Second, to implement a caloric sweetened beverage tax. Third, to examine how to implement fruit and vegetable subsidies targeted at children and low income households. Conclusions In terms of economic interventions, shifting from empirical evidence to policy recommendation remains challenging. Overall, the evidence is not sufficiently strong to provide clear policy direction. Additionally

  11. On speaking terms: a Delphi study on shared decision-making in maternity care

    PubMed Central

    2014-01-01

    Background For most women, participation in decision-making during maternity care has a positive impact on their childbirth experiences. Shared decision-making (SDM) is widely advocated as a way to support people in their healthcare choices. The aim of this study was to identify quality criteria and professional competencies for applying shared decision-making in maternity care. We focused on decision-making in everyday maternity care practice for healthy women. Methods An international three-round web-based Delphi study was conducted. The Delphi panel included international experts in SDM and in maternity care: mostly midwives, and additionally obstetricians, educators, researchers, policy makers and representatives of care users. Round 1 contained open-ended questions to explore relevant ingredients for SDM in maternity care and to identify the competencies needed for this. In rounds 2 and 3, experts rated statements on quality criteria and competencies on a 1 to 7 Likert-scale. A priori, positive consensus was defined as 70% or more of the experts scoring ≥6 (70% panel agreement). Results Consensus was reached on 45 quality criteria statements and 4 competency statements. SDM in maternity care is a dynamic process that starts in antenatal care and ends after birth. Experts agreed that the regular visits during pregnancy offer opportunities to build a relationship, anticipate situations and revisit complex decisions. Professionals need to prepare women antenatally for unexpected, urgent decisions in birth and revisit these decisions postnatally. Open and respectful communication between women and care professionals is essential; information needs to be accurate, evidence-based and understandable to women. Experts were divided about the contribution of professional advice in shared decision-making and about the partner’s role. Conclusions SDM in maternity care is a dynamic process that takes into consideration women’s individual needs and the context of the

    Digital flood-inundation maps for an 11-mile reach of the Tippecanoe River that extends from County Road W725N to State Road 18 below Oakdale Dam, Indiana (Ind.), were created by the U.S. Geological Survey (USGS) in cooperation with the Indiana Department of Transportation. The inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/flood_inundation/, depict estimates of the areal extent of flooding corresponding to selected water levels (stages) at USGS streamgage 03333050, Tippecanoe River near Delphi, Ind. Current conditions at the USGS streamgages in Indiana may be obtained online at http://waterdata.usgs.gov/in/nwis/current/?type=flow. In addition, the information has been provided to the National Weather Service (NWS) for incorporation into their Advanced Hydrologic Prediction Service (AHPS) flood warning system (http://water.weather.gov/ahps/). The NWS forecasts flood hydrographs at many places that are often co-located at USGS streamgages. That forecasted peak-stage information, also available on the Internet, may be used in conjunction with the maps developed in this study to show predicted areas of flood inundation. In this study, water-surface profiles were simulated for the stream reach by means of a hydraulic one-dimensional step-backwater model. The model was calibrated by using the most current stage-discharge relation at USGS streamgage 03333050, Tippecanoe River near Delphi, Ind., and USGS streamgage 03332605, Tippecanoe River below Oakdale Dam, Ind. The hydraulic model was then used to simulate 13 water-surface profiles for flood stages at 1-foot intervals reference to the streamgage datum and ranging from bankfull to approximately the highest recorded water level at the streamgage. The simulated water-surface profiles were then combined with a geographic information system digital elevation model (derived from Light Detection and Ranging (LiDAR) data) in order to delineate the

    OBJECTIVE Development of a numerical score to measure the microbial spectrum of antibiotic regimens (spectrum score) and method to identify antibiotic de-escalation events based on application of the score. DESIGN Web-based modified Delphi method. PARTICIPANTS Physician and pharmacist antimicrobial stewards practicing in the United States recruited through infectious diseases–focused listservs. METHODS Three Delphi rounds investigated: organisms and antibiotics to include in the spectrum score, operationalization of rules for the score, and de-escalation measurement. A 4-point ordinal scale was used to score antibiotic susceptibility for organism-antibiotic domain pairs. Antibiotic regimen scores, which represented combined activity of antibiotics in a regimen across all organism domains, were used to compare antibiotic spectrum administered early (day 2) and later (day 4) in therapy. Changes in spectrum score were calculated and compared with Delphi participants’ judgments on de-escalation with 20 antibiotic regimen vignettes and with non-Delphi steward judgments on de-escalation of 300 pneumonia regimen vignettes. Method sensitivity and specificity to predict expert de-escalation status were calculated. RESULTS Twenty-four participants completed all Delphi rounds. Expert support for concepts utilized in metric development was identified. For vignettes presented in the Delphi, the sign of change in score correctly classified de-escalation in all vignettes except those involving substitution of oral antibiotics. The sensitivity and specificity of the method to identify de-escalation events as judged by non-Delphi stewards were 86.3% and 96.0%, respectively. CONCLUSIONS Identification of de-escalation events based on an algorithm that measures microbial spectrum of antibiotic regimens generally agreed with steward judgments of de-escalation status.

    Although traumatic brain injury (TBI) can happen to anyone at any time, the wars in Iraq and Afghanistan have brought it renewed attention. Fortunately, most cases of TBI from the recent conflicts are mild TBI (mTBI). Still, many physical, psychological, and social problems are associated with mTBI. Among the difficulties encountered are oculomotor and vision problems, many of which can impede daily activities such as reading. Therefore, correct diagnosis and treatment of these mTBI-related vision problems is an important part of patient recovery. Numerous eye care providers in the Department of Veterans Affairs, in military settings, and in civilian practices specialize and are proficient in examining patients who have a history of TBI. However, many do not have this level of experience working with and treating patients with mTBI. Recognizing this, we used a modified Delphi method to derive expert opinions from a panel of 16 optometrists concerning visual examination of the patient with mTBI. This process resulted in a clinical tool containing 17 history questions and 7 examination procedures. This tool provides a set of clinical guidelines that can be used as desired by any eye care provider either as a screening tool or adjunct to a full eye examination when seeing a patient with a history of mTBI. The goal of this process was to provide optimal and uniform vision care for the patient with mTBI. PMID:24203539

    Uncertainty about future costs and operating attributes of electric drive vehicles (EVs and HEVs) has contributed to considerable debate regarding the market viability of such vehicles. One way to deal with such uncertainty, common to most emerging technologies, is to pool the judgments of experts in the field. Data from a two-stage Delphi study are used to project the future costs and operating characteristics of electric drive vehicles. The experts projected basic vehicle characteristics for EVs and HEVs for the period 2000-2020. They projected the mean EV range at 179 km in 2000, 270 km in 2010, and 358 km in 2020. The mean HEV range on battery power was projected as 145 km in 2000, 212 km in 2010, and 244 km in 2020. Experts` opinions on 10 battery technologies are analyzed and characteristics of initial battery packs for the mean power requirements are presented. A procedure to compute the cost of replacement battery packs is described, and the resulting replacement costs are presented. Projected vehicle purchase prices and fuel and maintenance costs are also presented. The vehicle purchase price and curb weight predictions would be difficult to achieve with the mean battery characteristics. With the battery replacement costs added to the fuel and maintenance costs, the conventional ICE vehicle is projected to have a clear advantage over electric drive vehicles through the projection period.

  16. A decision-making framework for total ownership cost management of complex systems: A Delphi study

    King, Russel J.

    This qualitative study, using a modified Delphi method, was conducted to develop a decision-making framework for the total ownership cost management of complex systems in the aerospace industry. The primary focus of total ownership cost is to look beyond the purchase price when evaluating complex system life cycle alternatives. A thorough literature review and the opinions of a group of qualified experts resulted in a compilation of total ownership cost best practices, cost drivers, key performance factors, applicable assessment methods, practitioner credentials and potential barriers to effective implementation. The expert panel provided responses to the study questions using a 5-point Likert-type scale. Data were analyzed and provided to the panel members for review and discussion with the intent to achieve group consensus. As a result of the study, the experts agreed that a total ownership cost analysis should (a) be as simple as possible using historical data; (b) establish cost targets, metrics, and penalties early in the program; (c) monitor the targets throughout the product lifecycle and revise them as applicable historical data becomes available; and (d) directly link total ownership cost elements with other success factors during program development. The resultant study framework provides the business leader with incentives and methods to develop and implement strategies for controlling and reducing total ownership cost over the entire product life cycle when balancing cost, schedule, and performance decisions.

  17. Developing a driving Safety Index using a Delphi stated preference experiment.

    2008-03-01

    Whilst empirical evidence is available concerning the effect of some aspects of driving behaviour on safety (e.g. speed choice), there is scant knowledge about safety thresholds, i.e. the point at which behaviour can be considered unsafe. Furthermore, it is almost impossible to ascertain the interaction between various aspects of driving behaviour. For example, how might drivers' lateral control of a vehicle be mediated by their speed choice-are the effects additive or do they cancel each other out. Complex experimental or observational studies would need to be undertaken to establish the nature of such effects. As an alternative, a Delphi study was undertaken to use expert judgement as a way of deriving a first approximation of these threshold and combinatory effects. Using a stated preference technique, road safety professionals make judgements about drivers' safe or unsafe behaviour. The aim was to understand the relative weightings that are assigned to a number of driver behaviours and thereby to construct a Safety Index. As expected, experts were able to establish thresholds, above (or below) which changes to the behavioural parameters had minimal impact on safety. This provided us with a Safety Index, based on a model that had face validity and a convincing range of values. However, the experts found the task of combining these driver behaviours more difficult, reflecting the elusive nature of safety estimates. Suggestions for future validation of our Safety Index are provided. PMID:18329392

    Introduction Environmental factors contribute with 16% of the burden of disease in Colombia. A main obstacle in implementing national and regional environmental and occupational health policies is the limited knowledge on the local ability to study and control the impact of harmful exposures on health. Objective To identify needs for research and training in environmental and occupational health in Colombia. Materials and methods We conducted a three-round hybrid Delphi study. A group of environmental and occupational health Colombian experts (n=16) from government agencies, universities, and research centers was recruited to participate in the study. Expert’s opinions on research and training needs were gathered through online questionnaires, followed by an in-person meeting. The percentage of agreement and the coefficient of variation were used to measure consensus. Results Air pollution and chemical products were considered the most important environmental and occupational exposures, due to their significant impact on chronic non-communicable diseases, such as respiratory diseases, cardiovascular diseases, and cancer. Research on the effects of outdoor air pollution on cardiovascular and respiratory diseases was considered of the greatest importance. Priority training areas included environmental and occupational health risk assessment, exposure modeling, advanced statistical methods, urban planning, occupational safety and hygiene, and epidemiology and toxicology. Conclusions These findings provide a valuable input for the definition and implementation of national environmental and occupational health policies and for the development of a regional hub aimed at strengthening the capacity for research and training in Colombia.

    The causes of mortality of nutritional origin (MNO) are not classified in the consecutive reviews of the international disease classification (IDC) and there is no agreement for their most proper classification. The objective of this study is to elaborate, using the last ICD as a guide, a list of causes of mortality of nutritional origin which will be used as a reference in future studies. A two round Delphi method was organized with an expert's consenssus in clinical nutrition. The experts were asked to classify a list of causes of MNO in 4 groups; 1) group A: congenital errors related to nutrition, 2) group B: Causes associated with other pathologies, 3) group 3: Excess and defect nutrition disorders, and 4) excluded. In total, 86 causes of MNO were taken under the consensus of experts, and 79 (91.9%) came to an agreement. 14 (17.7%) causes were classified in group A, 5 (6.3%) causes in group B, 37 (46.8%) causes in group C and 23 (29.1%) were excluded. This is a first approach to the classification of mortality causes of nutritional origin, probably due to the ambiguity and disparity of opinions between experts with respect to these causes. This new classification will be very useful due to the fact that it will enable homogenization of the studies and that way we will have comparable studies, using it as a clarifier annex for the ICD of the moment.

    The meat sector in Spain is an important industry. However, traditional consumption is changing as a result of the country's economic crisis and the new structure of households. The objective of the present study was to identify trends in meat consumption in Spain extrapolated to 2016, and the main innovations that should be of interest to firms in the sector. The study was conducted in 2011 using the Delphi method with the participation of 26 experts. The results showed that, while the demand for meat will not vary significantly in amount, it will do so in composition, with chicken replacing beef as the meat of most importance in the shopping basket. In addition, significant growth is expected in certified meat, but the demand for organic meat will not take off. Neither will there be no significant changes in end purchase formats, but there will be a clear trend in consumers' purchasing decision criteria away from price, external appearance and origin towards quality certification and the attributes of the packaging. With respect to end purchase channels, the experts estimate that the current trend will be accentuated with increasing market share for large supermarkets and major distribution brands.

    2005-01-01

    Background: Occupational physicians can contribute to good management in healthy enterprises. The requirement to take into account the needs of the customers when planning occupational health services is well established. Aims: To establish the priorities of UK employers, employees, and their representatives regarding the competencies they require from occupational physicians; to explore the reasons for variations of the priorities in different groups; and to make recommendations for occupational medicine training curricula in consideration of these findings. Methods: This study involved a Delphi survey of employers and employees from public and private organisations of varying business sizes, and health and safety specialists as well as trade union representatives throughout the UK. It was conducted in two rounds by a combination of computer assisted telephone interview (CATI) and postal survey techniques, using a questionnaire based on the list of competencies described by UK and European medical training bodies. Results: There was broad consensus about the required competencies of occupational physicians among the respondent subgroups. All the competencies in which occupational physicians are trained were considered important by the customers. In the order of decreasing importance, the competencies were: Law and Ethics, Occupational Hazards, Disability and Fitness for Work, Communication, Environmental Exposures, Research Methods, Health Promotion, and Management. Conclusion: The priorities of customers differed from previously published occupational physicians' priorities. Existing training programmes for occupational physicians should be regularly reviewed and where necessary, modified to ensure that the emphasis of training meets customer requirements. PMID:15901889

    1990-01-01

    The purpose of this study was to identify factors impeding development and use of interactive video (IAV) in nursing education in order to specify actions that would facilitate its development and use. Nurse educators with experience in development of IAV programs were defined as the experts, and a three-round Delphi study was conducted. Study findings revealed that participants were aware of obstacles to development and were able to suggest some ways to overcome them. Subjects clearly identified content they want in IAV programs, and were especially united on applications for simulations. They agreed on benefits of IAV for students, but were less certain about how it might affect faculty roles, and were undecided about measurable advantages of IAV. Conservative predictions were made about how evolving IAV technology might change the process of nurse education in the future. To promote IAV development and use the author recommends cooperative efforts between nurse educators and developers in the business sector and an educational thrust targeted for specific groups. Moving beyond existing nursing roles and institutional models, the author makes two major suggestions: establishment of a new nursing specialist, the nurse/instructional designer, and the creation of an information center staffed by these new specialists who will design and develop programs, provide education and consultation, maintain a clearinghouse for IAV programs, research, and technology, and take a leadership role in the integration of this powerful instructional delivery system into the entire health field.

    The uptake of advance care planning (ACP) is particularly low among people with dementia. This may reflect barriers to communication between professionals, patients and families in the face of lack of consensus about the process. This study aimed to methodically investigate consensus views of how ACP should be explained and carried out with people with dementia. A three-round Delphi study explored views of how and when ACP should be addressed, what should be covered, who should be involved and why rates of ACP are low. Seventeen participants took part comprising family members, old age psychiatrists and policy makers. Thirty-two items reached consensus. The panel agreed on 11 different areas for discussion. They concurred that ACP was best addressed after the person has come to terms with the diagnosis when the individual feels ready to do so. There was a consensus view that the process should be couched in terms of 'certain possibilities'. Consensus items emphasised personal choice and autonomy, while also prioritising the need to discuss financial aspects and to include spouses. There was no consensus that professionals should be involved, although the panel viewed them as carrying some responsibility for low uptake. It is suggested that ACP should include general discussion of values as well as coverage of specific points. Professionals need to offer discussion and information on ACP, but also make clear that the patient has the right to choose whether to pursue ACP or not. PMID:25684278

    Forty-seven common dolphins (Delphinus delphis ponticus) were stranded on the northern shores of the Black Sea between mid-July and early September 1994, more than in previous or subsequent years. Two of the 47 dolphins were examined in detail to try to determine the cause of the increased stranding rate. Their lesions included broncho-interstitial pneumonia with type II epithelial cell hyperplasia and multinucleate syncytial cells, neuronal necrosis, gliosis, and non-suppurative meningitis of the brain, necrotic stomatitis, gastroenteritis and cholangitis, and lymphoid depletion of the spleen and lymph nodes. The diseased tissues stained positive in an immunoperoxidase test, using a polyclonal antiserum to measles virus as the primary antibody, and electron microscopy showed that they contained regularly-shaped intranuclear particles about 22 nm in diameter. They were positive by the polymerase chain reaction (PCR) for the nucleoprotein gene of morbillivirus. However, there was no evidence of morbillivirus in frozen tissues either by virus isolation or by antigen capture ELISA. The concentration of sigma DDTS in the blubber of both dolphins was about 50 to 100 times higher than the levels in toothed cetaceans from the North Sea, North Atlantic Ocean, and Baltic Sea. The lesions were consistent with those found in other species with morbilliviral disease, and the positive immunoperoxidase test, PCR and electron microscopical examination confirmed a morbillivirus as the primary cause of these lesions.

    Background. Triage nurses play a pivotal role in the emergency department. However some researchers have attempted to expand triage nurse's role; remarkable discrepancies exist among scholarly communities. The aim was to develop a role description of triage nurse relying on the experts. Methods. A modified Delphi study consisting of 3 rounds was performed from March to October 2014. In the first round, an extensive review of the literature was conducted. Expert selection was conducted through a purposeful sample of 38 emergency medicine experts. Results. Response rates for the second and third rounds were 37% and 58%. Average age of panelists was (38.42 ± 5.94) years. Thirty-nine out of 54 items reached to the final round. Prioritizing had the higher agreement rate and least agreement on triage related interventions. Conclusion. Triage nursing as a relatively new role for nurses needs significant development to be practiced. Comprehensive educational programs and developmental research are required to support diagnostic and therapeutic interventions in triage practice by nurses. PMID:27382500

    Background This study aimed to have international experts converge on a harmonized definition of whole hippocampus boundaries and segmentation procedures, to define standard operating procedures for magnetic resonance (MR)-based manual hippocampal segmentation. Methods The panel received a questionnaire regarding whole hippocampus boundaries and segmentation procedures. Quantitative information was supplied to allow evidence-based answers. A recursive and anonymous Delphi procedure was used to achieve convergence. Significance of agreement among panelists was assessed by exact probability on Fisher’s and binomial tests. Results Agreement was significant on the inclusion of alveus/fimbria (P =.021), whole hippocampal tail (P =.013), medial border of the body according to visible morphology (P =.0006), and on this combined set of features (P =.001). This definition captures 100% of hippocampal tissue, 100% of Alzheimer’s disease-related atrophy, and demonstrated good reliability on preliminary intrarater (0.98) and inter-rater (0.94) estimates. Discussion Consensus was achieved among international experts with respect to hippocampal segmentation using MR resulting in a harmonized segmentation protocol. PMID:25130658

    Resource allocation in the Irish health service, based on historical allocations with incremental increases, is widely believed to be inequitable. Using a three-round policy Delphi survey, which seeks to explore both consensus and disagreement surrounding policy issues, the views of 52 senior health service personnel were sought in order to determine ways to improve equity in resource allocation. Panelists provided several reasons why the current method of resource allocation is inequitable and several suggestions for improving equity. The level of consensus on views was determined by calculating the percentage of ratings in each category based on a series of rating scales. The main suggestion centred around the development and implementation of a needs based resource allocation formula. Panelists reached a high consensus in favour of this but only reached a low consensus as to its feasibility. Potential obstacles identified included methodological difficulties, insufficient resources and resistance from potential losers. These findings highlight concerns about the lack of transparency in the resource allocation process and openness to the development of a more equitable needs based resource allocation model, a move which is becoming more common internationally. Feasibility concerns should not preclude an attempt to begin this process. PMID:15036815

    Much has been written about interventions to improve the nursing work environment, yet little is known about their effectiveness. A Delphi survey of nurse experts was conducted to explore perceptions about workplace interventions in terms of feasibility and likelihood of positive impact on nurse outcomes such as job satisfaction and nurse retention. The interventions that received the highest ratings for likelihood of positive impact included: bedside handover to improve communication at shift report and promote patient-centred care; training program for nurses in dealing with violent or aggressive behaviour; development of charge nurse leadership team; training program focused on creating peer-supportive atmospheres and group cohesion; and schedule that recognizes work balance and family demands. The overall findings are consistent with the literature that highlights the importance of communication and teamwork, nurse health and safety, staffing and scheduling practices, professional development and leadership and mentorship. Nursing researchers and decision-makers should work in collaboration to implement and evaluate interventions for promoting practice environments characterized by effective communication and teamwork, professional growth and adequate support for the health and well-being of nurses.

    In this study, we examined the development of industry-oriented safety degree curricula at a college level. Based on a review of literature on the practices and study of the development of safety curricula, we classified occupational safety and health curricula into the following three domains: safety engineering, health engineering, and safety and health management. We invited 44 safety professionals to complete a four-round survey that was designed using a modified Delphi technique. We used Chi-square statistics to test the panel experts' consensus on the significance of the items in the three domains and employed descriptive statistics to rank the participants' rating of each item. The results showed that the top three items for each of the three domains were Risk Assessment, Dangerous Machinery and Equipment, and Fire and Explosion Prevention for safety engineering; Ergonomics, Industrial Toxicology, and Health Risk Assessment for health engineering; and Industrial Safety and Health Regulations, Accident Investigation and Analysis, and Emergency Response for safety and health management. Only graduates from safety programmes who possess practical industry-oriented abilities can satisfy industry demands and provide value to the existence of college safety programmes. PMID:26104789

    NASA's venerable LCAS sounding rocket program has been the primary means to test new space instrumentation for space physics, for over 60 years. Recently, new LCAS pathways have been introduced for instruments and science that require longer exposure than a sounding rocket affords. The International Space Station (ISS) offers similar infrastructure to a sounding rocket, with ample mass and volume, controlled attitude, and predefined and generous power and telemetry interfaces. The DEmonstration LEO Polarizing Heliospheric Imager is an LCAS mission that pioneers replacing the SPARCS+black brant stack with the ISS itself, to exploit the environment afforded by the ISS and demonstrate new instrumentation on-orbit. DELPHI is a solar off-pointed heliospheric imager that demonstrates the use of pB/B and quantitative photometry to locate solar wind features in 3-D with high spatial resolution, in a few-month mission. It makes use of the stable environment and high telemetry volume (1Mbps) on ISS to improve image quality with ground postprocessing. It is built on the ISS-standard ExPA interface and robotically deployed from the Space-X Dragon trunk to an external mount location. We will discuss some of the engineering and programmatic trades go with designing an orbital sounding-rocket-class instrument, and advocate using ISS as a future platform for instrument development.

    In today's highly rival market, an effective supplier selection process is vital to the success of any manufacturing system. Selecting the appropriate supplier is always a difficult task because suppliers posses varied strengths and weaknesses that necessitate careful evaluations prior to suppliers' ranking. This is a complex process with many subjective and objective factors to consider before the benefits of supplier selection are achieved. This paper identifies six extremely critical criteria and thirteen sub-criteria based on the literature. A new methodology employing those criteria and sub-criteria is proposed for the assessment and ranking of a given set of suppliers. To handle the subjectivity of the decision maker's assessment, an integration of fuzzy Delphi with fuzzy inference system has been applied and a new ranking method is proposed for supplier selection problem. This supplier selection model enables decision makers to rank the suppliers based on three classifications including "extremely preferred", "moderately preferred", and "weakly preferred". In addition, in each classification, suppliers are put in order from highest final score to the lowest. Finally, the methodology is verified and validated through an example of a numerical test bed.

    Introduction Feedback on patient satisfaction (PS) as a means to monitor and improve performance in patient communication is lacking in residency training. A physician’s promotion, compensation and job satisfaction may be impacted by his individual PS scores, once he is in practice. Many communication and satisfaction surveys exist but none focus on the emergency department setting for educational purposes. The goal of this project was to create an emergency medicine-based educational PS survey with strong evidence for content validity. Methods We used the Delphi Method (DM) to obtain expert opinion via an iterative process of surveying. Questions were mined from four PS surveys as well as from group suggestion. The DM analysis determined the structure, content and appropriate use of the tool. The group used four-point Likert-type scales and Lynn’s criteria for content validity to determine relevant questions from the stated goals. Results Twelve recruited experts participated in a series of seven surveys to achieve consensus. A 10-question, single-page survey with an additional page of qualitative questions and demographic questions was selected. Thirty one questions were judged to be relevant from an original 48-question list. Of these, the final 10 questions were chosen. Response rates for individual survey items was 99.5%. Conclusion The DM produced a consensus survey with content validity evidence. Future work will be needed to obtain evidence for response process, internal structure and construct validity.

    Cetaceans are difficult to observe in the wild, and demand complex logistics for dedicated collection of biological data. As such, the distribution of most cetacean species is still poorly understood. Ecological niche models are useful in studying species distributions and their ecological determinants, and platforms of opportunity (e.g. commercial nautical operators) can provide an alternative source for that data in cetaceans. In this study, we modelled common dolphin ( Delphinus delphis) habitat preferences using ecological niche modelling and presence data obtained from distinct platforms of opportunity in two different areas in the Portuguese coast (west and south mainland Portugal) for the period 2005-2007. Models from southern Portugal were projected to western Portugal and vice-versa, to check for robustness in predicting the species ecological niche. Our results show that data from platforms of opportunity can result in robust ecological models and provide extremely useful information on cetacean ecology. We found that common dolphins exhibit a patchy distribution pattern over the Portuguese coastline, and identified key habitats for their occurrence. The most important variable associated with this species' distribution was chlorophyll concentration which, given the results from previous research, we hypothesise reflects an ecological specialisation on pelagic schooling fish. Given that the most abundant schooling fish species in Portugal is increasingly overexploited and in constant decline, more attention should be given to the conservation of common dolphin in Portuguese waters.

    Introduction Prescribing is complicated for people living with dementia, and careful consideration should be given to continuing and initiating all medicines. This study aims to elicit opinion and gain consensus on appropriate medicine use for people living with dementia in Australia to create a consensus-based list of explicit prescribing criteria. Methods and analysis A Delphi technique will be used to develop explicit criteria of medication use in adults aged 65 years and above. An interdisciplinary panel of Australian experts in geriatric therapeutics will be convened that will consist of a minimum of 10 participants. To develop the consensus-based criteria, this study will use an iterative, anonymous, multistaged approach with controlled feedback. Round 1 questionnaire will be administered, and subsequently qualitatively analysed. The round 1 results will be fed back to the panel members, and a round 2 questionnaire developed using questions on a five-point Likert scale. This process will repeat until consensus is developed, or diminishing returns are noted. Ethics and dissemination All participants will be provided with a participant information sheet, and sign a written consent form. Ethical approval has been granted from the University of Western Australia's Human Research Ethics Committee (HREC) (reference: RA/4/1/7172). We expect that data from this study will result in a paper published in a peer-reviewed clinical journal and will also present the results at conferences. PMID:26264272

    Inconsistencies in measurements of food parenting practices continue to exist. Fundamental to this problem is the lack of clarity about what is understood by different concepts of food parenting practices. The purpose of this study was to clarify food parenting practice concepts related to snacking. A three round Delphi study among an international group of experts (n = 63) was conducted. In the first round, an open-ended survey was used to collect food parenting practice descriptions and concept labels associated with those practices. In the second round, participants were asked to match up descriptions with the appropriate concept labels. The third and final round allowed participants to reconsider how descriptions and concept labels were matched, taking into account the opinions expressed in round two. Round one produced 408 descriptions of food parenting practices and 110 different concept names. Round two started with 116 descriptions of food parenting practices and 20 concept names. On 40 descriptions, consensus regarding the underlying concept name was reached in round two. Of the remaining 76 descriptions, consensus on 47 descriptions regarding the underlying concept name was reached in round three. The present study supports the essential process of consensus development with respect to food parenting practices concepts. PMID:24732407

    Introduction Given the sharp rise in opioid prescribing and heightened recognition of opioid addiction and overdose, opioid safety has become a priority. Clinical guidelines on long-term opioid therapy (LTOT) for chronic pain consistently recommend routine monitoring and screening for problematic behaviours. Yet, there is no consensus definition regarding what constitutes a problematic behaviour, and recommendations for appropriate management to inform front-line providers, researchers and policymakers are lacking. This creates a barrier to effective guideline implementation. Thus, our objective is to present the protocol for a Delphi study designed to: (1) elicit expert opinion to identify the most important problematic behaviours seen in clinical practice and (2) develop consensus on how these behaviours should be managed in the context of routine clinical care. Methods/analysis We will include clinical experts, defined as individuals who provide direct patient care to adults with chronic pain who are on LTOT in an ambulatory setting, and for whom opioid prescribing for chronic non-malignant pain is an area of expertise. The Delphi study will be conducted online in 4 consecutive rounds. Participants will be asked to list problematic behaviours and identify which behaviours are most common and challenging. They will then describe how they would manage the most frequently occurring common and challenging behaviours, rating the importance of each management strategy. Qualitative analysis will be used to categorise behaviours and management strategies, and consensus will be based on a definition established a priori. Ethics/dissemination This study has been approved by the Institutional Review Board (IRB) of the University of Alabama at Birmingham (UAB). This study will generate Delphi-based expert consensus on the management of problematic behaviours that arise in individuals on LTOT, which we will publish and disseminate to appropriate professional societies

    Introduction The science underpinning mass-gathering health (MGH) is developing rapidly. However, MGH terminology and concepts are not yet well defined or used consistently. These variations can complicate comparisons across settings. There is, therefore, a need to develop consensus and standardize concepts and data points to support the development of a robust MGH evidence-base for governments, event planners, responders, and researchers. This project explored the views and sought consensus of international MGH experts on previously published concepts around MGH to inform the development of a transnational minimum data set (MDS) with an accompanying data dictionary (DD). Report A two-round Delphi process was undertaken involving volunteers from the World Health Organization (WHO) Virtual Interdisciplinary Advisory Group (VIAG) on Mass Gatherings (MGs) and the MG section of the World Association for Disaster and Emergency Medicine (WADEM). The first online survey tested agreement on six key concepts: (1) using the term "MG HEALTH;" (2) purposes of the proposed MDS and DD; (3) event phases; (4) two MG population models; (5) a MGH conceptual diagram; and (6) a data matrix for organizing MGH data elements. Consensus was defined as ≥80% agreement. Round 2 presented five refined MGH principles based on Round 1 input that was analyzed using descriptive statistics and content analysis. Thirty-eight participants started Round 1 with 36 completing the survey and 24 (65% of 36) completing Round 2. Agreement was reached on: the term "MGH" (n=35/38; 92%); the stated purposes for the MDS (n=38/38; 100%); the two MG population models (n=31/36; 86% and n=30/36; 83%, respectively); and the event phases (n=34/36; 94%). Consensus was not achieved on the overall conceptual MGH diagram (n=25/37; 67%) and the proposed matrix to organize data elements (n=28/37; 77%). In Round 2, agreement was reached on all the proposed principles and revisions, except on the MGH diagram (n=18/24; 75

  18. Study of rare decays of the b quark with the DELPHI detector at LEP

    NASA Astrophysics Data System (ADS)

    Battaglia, Marco

    The b quark is the heaviest fermion producing bound hadronic states. The study of their production and decays provides important data for the understanding of the processes responsible for the weak decays of fundamental fermions. In addition, due to the small value of the | Vcb| element, suppressed and rare b-->u and b-->s, d transitions are not completely obliterated by the CKM favoured b-->c decays. This makes B hadrons an ideal laboratory for the study of rare decay processes. The sensitivity of these decays to the Standard Model structure, through suppressions proportional to the square of the elements in the quark mixing matrix and through loops that may reveal contributions of new particles, opens a new window on precision tests of the Standard Model and also on possible new physics beyond it. The DELPHI detector, equipped with a precise silicon vertex tracker surrounding the beam interaction region and with Ping Imaging CHerenkov (RICH) detectors providing efficient hadron identification, at the LEP e +e- collider, is well suited for precise studies of B decays. This thesis presents the results of the analysis of the date, collected with DELPHI at centre-of-mass energies around the Z0 pole from 1990 to 1995 for the studies of rare decays of beauty hadrons. These studies have promoted the development of new techniques for the topological reconstruction of the B decay chain and for hadron identification based on the response of the RICH detectors. Rare decays of the b quarks have been studied in several decay processes. Tree level b-->u transitions have been studied mainly in the semileptonic b-->uln channel. A new technique that discriminate them from the favoured b-->c transitions based on the reconstructed mass of the hadronic system recoiling against the lepton has been developed and applied. Evidence for the decay has been obtained and its rate has been used to extract an accurate determination of the |Vub| element in the quark mixing matrix. Hadronic

    Objective To develop a set of quality criteria for patient decision support technologies (decision aids). Design and setting Two stage web based Delphi process using online rating process to enable international collaboration. Participants Individuals from four stakeholder groups (researchers, practitioners, patients, policy makers) representing 14 countries reviewed evidence summaries and rated the importance of 80 criteria in 12 quality domains ona1to9 scale. Second round participants received feedback from the first round and repeated their assessment of the 80 criteria plus three new ones. Main outcome measure Aggregate ratings for each criterion calculated using medians weighted to compensate for different numbers in stakeholder groups; criteria rated between 7 and 9 were retained. Results 212 nominated people were invited to participate. Of those invited, 122 participated in the first round (77 researchers, 21 patients, 10 practitioners, 14 policy makers); 104/122 (85%) participated in the second round. 74 of 83 criteria were retained in the following domains: systematic development process (9/9 criteria); providing information about options (13/13); presenting probabilities (11/13); clarifying and expressing values (3/3); using patient stories (2/5); guiding/coaching (3/5); disclosing conflicts of interest (5/5); providing internet access (6/6); balanced presentation of options (3/3); using plain language (4/6); basing information on up to date evidence (7/7); and establishing effectiveness (8/8). Conclusions Criteria were given the highest ratings where evidence existed, and these were retained. Gaps in research were highlighted. Developers, users, and purchasers of patient decision aids now have a checklist for appraising quality. An instrument for measuring quality of decision aids is being developed. PMID:16908462

    Marine mammals are regularly reported as bycatch in commercial and artisanal fisheries, but data are often insufficient to allow assessment of these incidental mortalities. Observer coverage of the mackerel trawl fishery in New Zealand waters between 1995 and 2011 allowed evaluation of common dolphin Delphinus delphis bycatch on the North Island west coast, where this species is the most frequently caught cetacean. Observer data were used to develop a statistical model to estimate total captures and explore covariates related to captures. A two-stage Bayesian hurdle model was used, with a logistic generalised linear model predicting whether any common dolphin captures occurred on a given tow of the net, and a zero-truncated Poisson distribution to estimate the number of dolphin captures, given that there was a capture event. Over the 16-year study period, there were 119 common dolphin captures reported on 4299 observed tows. Capture events frequently involved more than one individual, with a maximum of nine common dolphin observed caught in a single tow. There was a peak of 141 estimated common dolphin captures (95% c.i.: 56 to 276; 6.27 captures per 100 tows) in 2002–03, following the marked expansion in annual effort in this fishery to over 2000 tows. Subsequently, the number of captures fluctuated although fishing effort remained relatively high. Of the observed capture events, 60% were during trawls where the top of the net (headline) was <40 m below the surface, and the model determined that this covariate best explained common dolphin captures. Increasing headline depth by 21 m would halve the probability of a dolphin capture event on a tow. While lack of abundance data prevents assessment of the impact of these mortalities on the local common dolphin population, a clear recommendation from this study is the increasing of headline depth to reduce common dolphin captures.

    Objectives In some countries, nicotine-containing electronic cigarettes (e-cigarettes) are considered a consumer product without specific regulations. In others (eg, Switzerland), the sale of e-cigarettes containing nicotine is forbidden, despite the eagerness of many smokers to obtain them. As scientific data about efficacy and long-term safety of these products are scarce, tobacco control experts are divided on how to regulate them. In order to gain consensus among experts to provide recommendations to health authorities, we performed a national consensus study. Setting We used a Delphi method with electronic questionnaires to bring together the opinion of Swiss experts on e-cigarettes. Participants 40 Swiss experts from across the country. Outcome measures We measured the degree of consensus between experts on recommendations regarding regulation, sale, use of and general opinion about e-cigarettes containing nicotine. New recommendations and statements were added following the experts’ answers and comments. Results There was consensus that e-cigarettes containing nicotine should be made available, but only under specific conditions. Sale should be restricted to adults, using quality standards, a maximum level of nicotine and with an accompanying list of authorised ingredients. Advertisement should be restricted and use in public places should be forbidden. Conclusions These recommendations encompass three principles: (1) the reality principle, as the product is already on the market; (2) the prevention principle, as e-cigarettes provide an alternative to tobacco for actual smokers, and (3) the precautionary principle, to protect minors and non-smokers, since long-term effects are not yet known. Swiss authorities should design specific regulations to sell nicotine-containing e-cigarettes. PMID:25877274

    Background Emergency medicine is a rapidly developing field in South Africa (SA) and other developing nations. There is a need to develop performance indicators that are relevant and easy to measure. This will allow identification of areas for improvement, create standards of care and allow inter-institutional comparisons to be made. There is evidence from the international literature that performance measures do lead to performance improvements. Aims To develop a broad-based consensus document detailing quality measures for use in SA Emergency Centres (ECs). Methods A three-round modified Delphi study was conducted over e-mail. A panel of experts representing the emergency medicine field in SA was formed. Participants were asked to provide potential performance indicators for use in SA, under subheaders of the various disciplines that are seen in emergency patients. These statements were collated and sent out to the panel for scoring on a 9-point Lickert scale. Statements that did not reach a predefined consensus were sent back to the panellist for reconsideration. Results Consensus was reached on 99 out of 153 (65%) of the performance indicators proposed. These were further refined, and a synopsis of the statements is presented, classified as to whether the statements were thought to be feasible or not in the current circumstances.

    Ensuring that people living in nursing homes (NHs) are afforded with dignity in their daily lives is an essential and humane concern. Promoting dignity-conserving care is fundamentally important. By nature, however, this care is all-encompassing and holistic, and from current knowledge it is challenging to create explicit strategies for measuring dignity-conserving care. In practice the majority of current NH indicators of quality care are derived from information that is routinely collected on NH residents using the RAI-Minimum Data Set (MDS). In this regard, issues that are more tangible to resident dignity such as being treated with respect, compassion, and having opportunities to engage with others are not adequately captured in current NH quality of care indicators. An initial set of markers was created by conducting an integrative literature review of existing markers and indicators of dignity in the NH setting. A modified Delphi process was used to prioritize essential dignity-conserving care markers for use by NH providers, based on factors such as the importance to fostering a culture of dignity, the impact it may have on the residents, and how achievable it is in practice. Through this consensus building technique, we were able to develop a comprehensive set of markers that capture the range and diversity of important dignity-conserving care strategies for use in NHs. The final 10 markers were judged as having high face validity by experts in the field and have explicit implications for enhancing the provision of daily dignified care to NH residents. These markers make an important addition to the traditional quality indicators used in the NH setting and as such, bridge an important gap in addressing the psychosocial and the less easily quantified needs of NH residents.

    The Delphi process, widely used in health research to seek consensus on key issues amongst large stakeholder groups, was adopted to allow families, hospice staff/volunteers and linked professionals to identify and prioritize future research priorities for children's hospice care. In the qualitative Round 1, interviews with families (n = 5), linked professionals (n = 18) and focus groups with hospice staff and volunteers (n = 44) led to the generation of 56 research topics categorised within 14 broad themes. To give a larger number of stakeholders (n = 621) (including families n = 293; hospice staff/volunteers n = 216 and professionals n = 112) the opportunity to rate the importance of each research topic and seek group consensus on the future research priorities for children's hospice care, subsequent Rounds 2 and 3 involved the use of postal questionnaires. Response rates to questionnaires were 44% in Round 2 (274/621) and 83% in Round 3 (204/247). Participants prioritized research topics relating to 1) hospice and respite care needs of young people (aged 16 +), 2) pain and symptom management and 3) bereavement and end-of-life care. There was wide acknowledgement by those took part in the process of the difficulty in rating the topics, and emphasis on the fact that all of the topics raised during the project are of high importance and merit further research. The current salient issues perceived by key stakeholders as being the research priorities for children's hospice care were identified. Addressing these priority topics for research would further contribute to the development of a much needed evidence base in children's hospice and palliative care research and optimise the delivery of children's hospice services that are underpinned by valid and robust research.

    Genetic counselling for presymptomatic testing is complex, bringing both ethical and practical questions. There are protocols for counselling but a scarcity of literature regarding quality assessment of such counselling practice. Generic quality assessment tools for genetic services are not specific to presymptomatic testing (PST). Therefore, the aim of this study was to identify aspects of effective counselling practice in PST for late-onset neurological disorders. We used the Delphi method to ascertain the views of relevant European experts in genetic counselling practice, ascertained via published literature and nomination by practitioners. Ethical approval was obtained. Questionnaires were sent electronically to a list of 45 experts, (Medical Doctors, Geneticists, Genetic Counsellors and Genetic Nurses), who each contributed to one to three rounds. In the first round, we provided a list of relevant indicators of quality of practice from a literature review. Experts were requested to evaluate topics in four domains: (a) professional standards; (b) service standards; (c) the consultant's perspective; and (d) protocol standards. We then removed items receiving less than 65% approval and added new issues suggested by experts. The second round was performed for the refinement of issues and the last round was aimed at achieving final consensus on high-standard indicators of quality, for inclusion in the assessment tool. The most relevant indicators were related to (1) consultant-centred practice and (2) advanced counselling and interpersonal skills of professionals. Defined high-standard indicators can be used for the development of a new tool for quality assessment of PST counselling practice. PMID:25689925

    Lack of standardization of terminology in low back pain (LBP) research has significantly impeded progress in this area. The diversity in existing definitions for a 'recurrence of an episode of LBP' and 'recurrent LBP' is an important example. The variety of definitions used by researchers working in this area has prevented comparison of results between trials and made meta-analyses of this data unfeasible. The aim of this study was to use a modified Delphi approach to gain consensus on definitions for a 'recurrence of an episode of LBP' (e.g. outcome event) and for 'recurrent LBP' (e.g. patient population). Existing definitions for both constructs were classified into the main features comprising the definition (e.g. 'duration of pain') and the items that defined each feature (e.g. 'pain lasting at least 24 h'). In each round, participants were asked to rate the importance of each feature to a definition of a 'recurrence of an episode of LBP', and a definition of 'recurrent LBP' and rank the items (defining each feature) in order of decreasing importance. Forty-six experts in LBP research, from nine different countries, participated in this study. Four rounds were completed with responses rates of 94, 91, 83, and 97% in rounds 1, 2, 3, and 4, respectively. Consensus definitions were reached in both areas with 95% of panel members supporting the definition of a 'recurrence of an episode of LBP' and 92% of panel members supporting the definition of 'recurrent LBP'. Future research is necessary to evaluate these definitions. PMID:21193932

    Objectives There is no international consensus on the components of anaphylaxis management plans and responsibility for their design and delivery is contested. We set out to establish consensus among relevant specialist and generalist clinicians on this issue to inform future randomized controlled trials. Design A two-round electronic Delphi study completed by a 25-person, multidisciplinary expert panel. Participants scored the importance of a range of statements on anaphylaxis management, identified from a systematic review of the literature, on a five-point scale ranging from ‘very important’ to ‘irrelevant’. Consensus was defined a priori as being achieved if 80% or more of panel members rated a statement as ‘important’ or ‘very important’ after Round 2. Setting Primary and secondary care and academic settings in the UK and Ireland. Participants Twenty-five medical, nursing and allied health professionals. Main outcome measures Consensus on the key components of anaphylaxis management plans. Results The response rate was 84% (n = 21) for Round 1 and 96% (n = 24) for Round 2. The key components of emergency care on which consensus was achieved included: awareness of trigger factors (100%); recognition and emergency management of reactions of different severity (100%); and clear information on adrenaline (epinephrine) use (100%). Consensus on longer-term management issues included: clear written guidelines on anaphylaxis management (96%); annual review of plans (87%); and plans that were tailored to individual needs (82%). Conclusions This national consensus-building exercise generated widespread agreement that emergency plans need to be simple, clear and generic, making them easy to implement in a crisis. In contrast, long-term plans need to be negotiated between patient/carers and professionals, and tailored to individual needs. The effectiveness of this expert-agreed long-term plan now needs to be evaluated rigorously. PMID:21103134

    2008-01-01

    Background Suicide is a statistically rare event, but devastating to those left behind and one of the worst possible outcomes associated with mental illness. Although a friend, family member or co-worker may be the first person to notice that a person is highly distressed, few have the knowledge and skills required to assist. Simple guidelines may help such a person to encourage a suicidal individual to seek professional help or decide against suicide. Methods This research was conducted using the Delphi methodology, a method of reaching consensus in a panel of experts. Experts recruited to the panels included 22 professionals, 10 people who had been suicidal in the past and 6 carers of people who had been suicidal in the past. Statements about how to assist someone who is thinking about suicide were sourced through a systematic search of both professional and lay literature. The guidelines were written using the items most consistently endorsed by all three panels. Results Of 114 statements presented to the panels, 30 were accepted. These statements were used to develop the guidelines appended to this paper. Conclusion There are a number of actions which are considered to be useful for members of the public when they encounter someone who is experiencing suicidal thoughts or engaging in suicidal behaviour. These guidelines will be useful in revision of curricula of mental health first aid and suicide intervention training programs. They can also be used by members of the public who want immediate information about how to assist a suicidal person. PMID:18366657

    2009-01-01

    Background Panic attacks are common, and while they are not life-threatening events, they can lead to the development of panic disorder and agoraphobia. Appropriate help at the time that a panic attack occurs may decrease the fear associated with the attack and reduce the risk of developing an anxiety disorder. However, few people have the knowledge and skills required to assist. Simple first aid guidelines may help members of the public to offer help to people who experience panic attacks. Methods The Delphi method was used to reach consensus in a panel of experts. Experts included 50 professionals and 6 people who had experience of panic attacks and were active in mental health advocacy. Statements about how to assist someone who is having a panic attack were sourced through a systematic search of both professional and lay literature. These statements were rated for importance as first aid guidelines by the expert and consumer panels and guidelines were written using the items most consistently endorsed. Results Of 144 statements presented to the panels, 27 were accepted. These statements were used to develop the guidelines appended to this paper. Conclusion There are a number of actions which are considered to be useful for members of the public to do if they encounter someone who is having a panic attack. These guidelines will be useful in revision of curricula of mental health first aid programs. They can also be used by members of the public who want immediate information about how to assist someone who is experiencing panic attacks. PMID:19664244

    Objective The purpose of this study was to develop a core set of indicators that could be used for measuring and monitoring the performance of primary health care organizations' capacity and strategies for enhancing equity-oriented care. Methods Indicators were constructed based on a review of the literature and a thematic analysis of interview data with patients and staff (n = 114) using procedures for qualitatively derived data. We used a modified Delphi process where the indicators were circulated to staff at the Health Centers who served as participants (n = 63) over two rounds. Indicators were considered part of a priority set of health equity indicators if they received an overall importance rating of>8.0, on a scale of 1–9, where a higher score meant more importance. Results Seventeen indicators make up the priority set. Items were eliminated because they were rated as low importance (<8.0) in both rounds and were either redundant or more than one participant commented that taking action on the indicator was highly unlikely. In order to achieve health care equity, performance at the organizational level is as important as assessing the performance of staff. Two of the highest rated “treatment” or processes of care indicators reflects the need for culturally safe and trauma and violence-informed care. There are four indicators that can be used to measure outcomes which can be directly attributable to equity responsive primary health care. Discussion These indicators and subsequent development of items can be used to measure equity in the domains of treatment and outcomes. These areas represent targets for higher performance in relation to equity for organizations (e.g., funding allocations to ongoing training in equity-oriented care provision) and providers (e.g., reflexive practice, skill in working with the health effects of trauma).

    Background: In order to incorporate new knowledge, skills and emerging concepts from dynamic fields of public health into ongoing courses reform of curriculums sounds necessary. Accordingly, this study was performed to modify health education curriculum of public health undergraduate level. Materials and Methods: Using Delphi technique, 18 health education lecturers from Tehran, Tabriz, Yazd, Shiraz, Gonabad, Ghazvin, Avhvaz and Kurdistan Universities Medical of Sciences based on their expertize in health education with PhD degree as scientific members, also 5 heads of departments according to working at health deputy for at least more than 5 years were asked during three rounds through panel experts to suggest and rate topics they deemed most important to graduate public health experts and curricula related to the areas of knowledge and skills in health education course. Results: The experts suggested that health enhancing behaviors and reduce health risks, advocate health, behavior change theories and developing a framework are key objects in the curriculum. Much more new topical outlines were related to previous course. Skills rated as important included need assessment and health communication. The most evaluators suggested that adding a practicum unit to two theory units will be helpful. Conclusion: The results from our survey suggested that changes in the course definition including new course objectives, topical outlines, and required skills were deemed important by the lecturers and were appropriately integrated into the health education course curriculum. The new curriculum should be evaluated constantly to seek and provide experiences that will best prepare students to meet challenges as a health educator. PMID:25540797

    Objective To evaluate health professionals' agreement with components of published diagnostic criteria for fetal alcohol spectrum disorders (FASD) in order to guide the development of standard diagnostic guidelines for Australia. Design A modified Delphi process was used to assess agreement among health professionals with expertise or experience in FASD screening or diagnosis. An online survey, which included 36 Likert statements on diagnostic methods, was administered over two survey rounds. For fetal alcohol syndrome (FAS), health professionals were presented with concepts from the Institute of Medicine (IOM), University of Washington (UW), Centers for Disease Control (CDC), revised IOM and Canadian diagnostic criteria. For partial FAS (PFAS), alcohol-related neurodevelopmental disorder (ARND), and alcohol-related birth defects (ARBD), concepts based on the IOM and the Canadian diagnostic criteria were compared. Setting/participants 130 Australian and 9 international health professionals. Results Of 139 health professionals invited to complete the survey, 103 (74.1%) responded, and 74 (53.2%) completed one or more questions on diagnostic criteria. We found consensus agreement among participants on the diagnostic criteria for FAS, with the UW criteria most commonly endorsed when compared with all other published criteria for FAS. When health professionals were presented with concepts based on the Canadian and IOM diagnostic criteria, we found consensus agreement but no clear preference for either the Canadian or IOM criteria for the diagnosis of PFAS, and no consensus agreement on diagnostic criteria for ARND. We also found no consensus on the IOM diagnostic criteria for ARBD. Conclusions Participants indicated clear support for use of the UW diagnostic criteria for FAS in Australia. These findings should be used to develop guidelines to facilitate improved awareness of, and address identified gaps in the infrastructure for, FASD diagnosis in Australia. PMID

  15. Incorporating the Delphi Technique to investigate renewable energy technology transfer in Saudi Arabia

    NASA Astrophysics Data System (ADS)

    Al-Otaibi, Nasir K.

    Saudi Arabia is a major oil-producing nation facing a rapidly-growing population, high unemployment, climate change, and the depletion of its natural resources, potentially including its oil supply. Technology transfer is regarded as a means to diversify countries' economies beyond their natural resources. This dissertation examined the opportunities and barriers to utilizing technology transfer successfully to build renewable energy resources in Saudi Arabia to diversify the economy beyond oil production. Examples of other developing countries that have successfully used technology transfer to transform their economies are explored, including Japan, Malayasia, and the United Arab Emirates. Brazil is presented as a detailed case study to illustrate its transition to an economy based to a much greater degree than before on renewable energy. Following a pilot study, the Delphi Method was used in this research to gather the opinions of a panel of technology transfer experts consisting of 10 heterogeneous members of different institutions in the Kingdom of Saudi Arabia, including aviation, telecommunication, oil industry, education, health systems, and military and governmental organizations. In three rounds of questioning, the experts identified Education, Dependence on Oil, and Manpower as the 3 most significant factors influencing the potential for success of renewable energy technology transfer for Saudi Arabia. Political factors were also rated toward the "Very Important" end of a Likert scale and were discussed as they impact Education, Oil Dependence, and Manpower. The experts' opinions are presented and interpreted. They form the basis for recommended future research and discussion of how in light of its political system and its dependence on oil, Saudi Arabia can realistically move forward on renewable energy technology transfer and secure its economic future.

    The introduction of Toyota's hybrid electric vehicle (HEV), the Prius, in Japan has generated considerable interest in HEV technology among US automotive experts. In a follow-up survey to Argonne National Laboratory's two-stage Delphi Study on electric and hybrid electric vehicles (EVs and HEVs) during 1994-1996, Argonne researchers gathered the latest opinions of automotive experts on the future ''top-selling'' HEV attributes and costs. The experts predicted that HEVs would have a spark-ignition gasoline engine as a power plant in 2005 and a fuel cell power plant by 2020. The projected 2020 fuel shares were about equal for gasoline and hydrogen, with methanol a distant third. In 2020, HEVs are predicted to have series-drive, moderate battery-alone range and cost significantly more than conventional vehicles (CVs). The HEV is projected to cost 66% more than a $20,000 CV initially and 33% more by 2020. Survey respondents view batteries as the component that contributes the most to the HEV cost increment. The mean projection for battery-alone range is 49 km in 2005, 70 km in 2010, and 92 km in 2020. Responding to a question relating to their personal vision of the most desirable HEV and its likely characteristics when introduced in the US market in the next decade, the experts predicted their ''vision'' HEV to have attributes very similar to those of the ''top-selling'' HEV. However, the ''vision'' HEV would cost significantly less. The experts projected attributes of three leading batteries for HEVs and projected acceleration times on battery power alone. The resulting battery packs are evaluated, and their initial and replacement costs are analyzed. These and several other opinions are summarized.

    The study presented in this article represents the second phase in a multi-phased research program focused on health care organization readiness for clinical information technology/system (IT/S) innovation. The overall purposes of this exploratory study were to: (1) validate the seven IT/S innovation readiness sub-dimensions of a heuristic organizational information technology/systems innovation model (OITIM) developed in phase one of the research program, and (2) identify indicators to assess the validated sub-dimensions. The study was conducted with an expert panel using a two-round modified Delphi technique. In Round #1, panelists supported retention of the OITIMs' seven theoretical IT/S innovation readiness sub-dimensions with an interrater agreement level range of 82-100%. Their sub-dimension importance ratings ranged from 3.27 to 3.72 (1=not important to 4=critically important) with the resources sub-dimension receiving the highest rating of 3.72. Panelists recommended that two sub-dimensions, 'Staffing and Skills' and 'Operations', be renamed to 'End-Users' and 'Management Structures', respectively, and that one sub-dimension, 'Administrative Support' be added. In Round #2, panelists identified a total of 316 indicators to assess the eight sub-dimensions. A two-step thematic analysis process was done with these indicators to reduce duplication and overlap. In Step 1, the investigator created ten preliminary theme categories per sub-dimension. In Step 2, a coding team categorized 279 (88%) of the 316 indicators into preliminary sub-dimension themes to create an organizational IT/S innovation readiness assessment taxonomy. This preliminary taxonomy was used to develop an organizational information technology/systems innovation readiness scale that is currently being pilot tested in phase three of the research program.

    A Silurian reef complex at Delphi, Indiana, consists of two subcircular reefs occupying an area of about 4 sq mi (10.6 sq km). The reef is more than 400 ft (62 m) thick, has a volume of about 0.15 cu mi (0.64 cu km), and effected as much as 75 ft (23 m) of compaction-induced drape in the overlying Middle Devonian strata. Stratigraphically, the complex extends upward from Salamonie (Middle Silurian) into Salina rocks (Upper Silurian). Growth of the complex proceeded through alternating periods of lateral expansion and restriction as reflected in the cross-sectional geometry of at least one of the reefs. These growth characteristics probably reflect the conditions that led to cyclic deposition of carbonate and evaporite rocks in the Michigan basin during Middle to Late Silurian time. Present dips along reef flanks locally exceed 35/sup 0/ but structural and stratigraphic analyses suggest that original depositional slopes may have been more gentle, that reef tops were never appreciably more than 200 ft (60 m) above the seafloor (although reef thicknesses of several hundred feet were attained before erosion), and that the central parts of the main reef masses were occupied by relatively rigid and volumetrically litle changing structural cores. Biozones include: two central areas of highest organic-framework buildup characterized by corals and stromatoporoids and flanking zones characterized separately by echinodermal and other debris, pentamerid brachiopods, gastropods, and fine debris and chert. The zonal distribution is similar to that already proposed for the large Silurian reef at Monon, Indiana, and somewhat resembles that proposed for the reef at Thornton, Illinois. These similarities and the fact of zonation in itself help to support the conclusion that the often debated Silurian buildups in the Great Lakes area satisfy all but the most rigid definitions of ecologic (organic-framework) reefs. 8 figures, 1 table.

    Purpose: Rapid evolution of imaging technologies and their integration into radiation therapy practice demands that radiation oncology (RO) training curricula be updated. The purpose of this study was to develop an entry-to-practice image literacy competency profile. Methods and Materials: A list of 263 potential imaging competency items were assembled from international objectives of training. Expert panel eliminated redundant or irrelevant items to create a list of 97 unique potential competency items. An international 2-round Delphi process was conducted with experts in RO. In round 1, all experts scored, on a 9-point Likert scale, the degree to which they agreed an item should be included in the competency profile. Items with a mean score ≥7 were included, those 4 to 6 were reviewed in round 2, and items scored <4 were excluded. In round 2, items were discussed and subsequently ranked for inclusion or exclusion in the competency profile. Items with >75% voting for inclusion were included in the final competency profile. Results: Forty-nine radiation oncologists were invited to participate in round 1, and 32 (65%) did so. Participants represented 24 centers in 6 countries. Of the 97 items ranked in round 1, 80 had a mean score ≥7, 1 item had a score <4, and 16 items with a mean score of 4 to 6 were reviewed and rescored in round 2. In round 2, 4 items had >75% of participants voting for inclusion and were included; the remaining 12 were excluded. The final list of 84 items formed the final competency profile. The 84 enabling competency items were aggregated into the following 4 thematic groups of key competencies: (1) imaging fundamentals (42 items); (2) clinical application (27 items); (3) clinical management (5 items); and (4) professional practice (10 items). Conclusions: We present an imaging literacy competency profile which could constitute the minimum training standards in radiation oncology residency programs.

    Objectives The competencies required of occupational physicians (OPs) have been the subject of peer-reviewed research in Europe and individual countries around the world. In the European Union (EU), there has been development of guidance on training and common competencies, but little research has extended beyond this. The aim of this study was to obtain consensus on and identify the common core competencies required of OPs around the world. Methods A modified Delphi study was carried out among representative organisations and networks of OPs in a range of countries around the world. It was conducted in 2 rounds using a questionnaire based on the specialist training syllabus of a number of countries, expert panel reviews and conference discussions. Results Responses were received from 51 countries around the world, with the majority from Europe (60%; 59%) and North and South America (24%; 32%) in rounds 1 and 2, respectively. General principles of assessment and management of occupational hazards to health and good clinical care were jointly considered most important in ranking when compared with the other topic areas. Assessment of disability and fitness for work, communication skills and legal and ethical issues completed the top five. In both rounds, research methods and teaching and educational supervision were considered least important. Conclusions This study has established the current priorities among OPs across 51 countries of the common competencies required for occupational health (OH) practice. These findings can serve as a platform for the development of common core competencies/qualifications within specific geographical regions or internationally. This is particularly pertinent with globalisation of commerce and free movement within the EU. PMID:27076063

    2013-01-01

    Background Over the last decade, sedentary behaviors have emerged as a distinctive behavioral paradigm with deleterious effects on health independent of physical activity. The next phase of research is to establish dose response between sedentary behaviors and health outcomes and improve understanding of context and determinants of these behaviors. Establishing a common taxonomy of these behaviors is a necessary step in this process. Aim The Sedentary behavior International Taxonomy project was developed to establish a classification of sedentary behaviors by use of a formal consensus process. Methods The study follows a Delphi process in three Rounds. A preparatory stage informed the development of terms of reference documents. In Round 1, experts were asked to make statements about the taxonomy; 1) its purpose and use ; 2) the domains, categories or facets that should be consider and include; 3) the structure/architecture to arrange and link these domains and facets. In Round 2 experts will be presented with a draft taxonomy emerging from Round 1 and invited to comment and propose alterations. The taxonomy will then be finalised at the outset of this stage. Results Results of Round 1 are reported here. There is a general consensus that a taxonomy will help advances in research by facilitating systematic and standardised: 1) investigation and analysis; 2) reporting and communication; 3) data pooling, comparison and meta-analysis; 4) development of measurement tools; 4) data descriptions, leading to higher quality in data querying and facilitate discoveries. There is also a consensus that such a taxonomy should be flexible to accommodate diverse purposes of use, and future advances in the field and yet provide a cross-disciplinary common language. A consensual taxonomy structure emerged with nine primary facets (Purpose, Environment, Posture, Social, Measurement, Associated behavior, Status, Time, Type) and the draft structure presented here for Round 2.

    Delayed or impaired language development is a common developmental concern, yet there is little agreement about the criteria used to identify and classify language impairments in children. Children's language difficulties are at the interface between education, medicine and the allied professions, who may all adopt different approaches to conceptualising them. Our goal in this study was to use an online Delphi technique to see whether it was possible to achieve consensus among professionals on appropriate criteria for identifying children who might benefit from specialist services. We recruited a panel of 59 experts representing ten disciplines (including education, psychology, speech-language therapy/pathology, paediatrics and child psychiatry) from English-speaking countries (Australia, Canada, Ireland, New Zealand, United Kingdom and USA). The starting point for round 1 was a set of 46 statements based on articles and commentaries in a special issue of a journal focusing on this topic. Panel members rated each statement for both relevance and validity on a seven-point scale, and added free text comments. These responses were synthesised by the first two authors, who then removed, combined or modified items with a view to improving consensus. The resulting set of statements was returned to the panel for a second evaluation (round 2). Consensus (percentage reporting 'agree' or 'strongly agree') was at least 80 percent for 24 of 27 round 2 statements, though many respondents qualified their response with written comments. These were again synthesised by the first two authors. The resulting consensus statement is reported here, with additional summary of relevant evidence, and a concluding commentary on residual disagreements and gaps in the evidence base. PMID:27392128

  3. Search for Pentaquarks in the Hadronic Decays of the Z Boson with the DELPHI Detector at LEP

    Recent evidence for pentaquark states has been published, in particular for a strange pentaquark {theta}+(1540), for a double-strange state called {xi}(1862)-- and for a charmed state {theta}c(3100)0. Such states should be produced in e+e- annihilations in Z decays. In this paper a search for pentaquarks using the DELPHI detector is described. Preliminary upper limits at 95% C.L. are set on the production rates per Z decay of such particles and their charge-conjugate state.

    Companies, seen as social communities, are major health promotion contexts. However, health promotion in the work setting is often less successful than intended. An optimal adjustment to the organisational context is required. Knowledge of which organisation-specific factors are relevant to health promotion is scarce. A Delphi procedure is used to identify these factors. The aim is to contribute to more effective workplace health promotion. The identified factors are described and embedded into a practical methodology (Intervention Mapping). A systematic use of these factors (called 'Organisational Mapping') is likely to contribute to more effective health promotion in the work setting. PMID:26573181

    Purpose. Spanish retina specialists were surveyed in order to propose actions to decrease deficiencies in real-life neovascular age macular degeneration treatment (nv-AMD). Methods. One hundred experts, members of the Spanish Vitreoretinal Society (SERV), were invited to complete an online survey of 52 statements about nv-AMD management with a modified Delphi methodology. Four rounds were performed using a 5-point Linkert scale. Recommendations were developed after analyzing the differences between the results and the SERV guidelines recommendations. Results. Eighty-seven specialists completed all the Delphi rounds. Once major potential deficiencies in real-life nv-AMD treatment were identified, 15 recommendations were developed with a high level of agreement. Consensus statements to reduce the burden of the disease included the use of treat and extend regimen and to reduce the amount of diagnostic tests during the loading phase and training technical staff to perform these tests and reduce the time between relapse detection and reinjection, as well as establishing patient referral protocols to outside general ophthalmology clinics. Conclusion. The level of agreement with the final recommendations for nv-AMD treatment among Spanish retinal specialist was high indicating that some actions could be applied in order to reduce the deficiencies in real-life nv-AMD treatment.

    Delphi method to identify education material on healthy food for teachers, school-age children and their parents. Delphi method applied to get expert consensus about healthy food topics to include in educational materials for preschool and school-age children, their parents and teachers is described. The questionnaire was developed with the results of surveys and focus groups in children, parents and teachers made previously. The questionnaire was mailed to 54 experts in nutrition, education and communication in a first round. The results were analyzed and forwarded in a second round with the subjects without consensus. The cycle was completed by a validation conducted with teachers and parents and were prioritized by audiovisual educational materials on the writings, favoring participatory activities such as cooking workshops, games, activities over the passive (information at parent meetings, delivery of educational materials and conferences of experts). There was consensus on education in health behaviors such as not giving them money to carry to school, make healthy food choices on family outings and recreational activities associated with healthy eating during weekends; prefer healthy food prepared at home instead of the processed food; restrict eating out candy and prefer family meals without watching TV and food instead of taking a snack in the evening. These results are critical to design educational materials on healthy eating plans to change current eating habits that are contributing significantly to increase the childhood obesity.

    Families with children living in areas of high deprivation face multiple health and social challenges, and this high level of need has impacts on the work of health practitioners working in such areas. All families in the UK with children under five years have access to health visiting services, and health visitors have a key role in mitigating the effects of deprivation by addressing health needs through evidence based practice. This paper reports the first stage of a project in Tower Hamlets, London, an area of significant deprivation, which aims to develop an evidence-based toolkit to support health visitors in their practice with families. The first stage used a modified Delphi process to identify the priority health needs of families in the area between June and July 2012. The three-stage Delphi process involved 25 people: four health visitors, four other members of the health visiting service, and 17 representatives of other services working with families. A focus group event was followed by a second event where individuals completed a questionnaire ranking the 27 priorities identified in the first event. The consultation process concluded with participants completing a second questionnaire, by email, confirming or changing their prioritisation of the topics. PMID:24151552

    The state of health (SOH) estimation is very critical to battery management system to ensure the safety and reliability of EV battery operation. Here, we used a unique hybrid approach to enable complex SOH estimations. The approach hybridizes the Delphi method known for its simplicity and effectiveness in applying weighting factors for complicated decision-making and the grey relational grade analysis (GRGA) for multi-factor optimization. Six critical factors were used in the consideration for SOH estimation: peak power at 30% state-of-charge (SOC), capacity, the voltage drop at 30% SOC with a C/3 pulse, the temperature rises at the end of discharge and charge at 1C; respectively, and the open circuit voltage at the end of charge after 1-h rest. The weighting of these factors for SOH estimation was scored by the 'experts' in the Delphi method, indicating the influencing power of each factor on SOH. The parameters for these factors expressing the battery state variations are optimized by GRGA. Eight battery cells were used to illustrate the principle and methodology to estimate the SOH by this hybrid approach, and the results were compared with those based on capacity and power capability. The contrast among different SOH estimations is discussed.

    We aimed to determine the scientific framework for research on disaster and mass casualty incident (MCI) in Korea, especially Korean terminology, feasible definition, and epidemiologic indices. The two staged policy Delphi method was performed by instructors of National Disaster Life Support (NDLS®) with the constructed questionnaire containing items based on the literature review. The first-stage survey was conducted by 11 experts through two rounds of survey for making issue and option. The second-stage survey was conducted by 35 experts for making a generalized group based consensus. Experts were selected among instructors of National Disaster Life Support Course. Through two staged Delphi survey experts made consensus: 1) the Korean terminology "jaenan" with "disaster" and "dajung-sonsang-sago" with "MCI"; 2) the feasible definition of "disaster" as the events that have an effect on one or more municipal local government area (city-county-district) or results in ≥ 10 of death or ≥ 50 injured victims; 3) the feasible definition of MCI as the events that result in ≥ 6 casualties including death; 4) essential 31 epidemiologic indices. Experts could determine the scientific framework in Korea for research on disaster medicine, considering the distinct characteristics of Korea and current research trends. PMID:24431916

    The dietetics profession lacks a comprehensive definition of advanced-level practice. Using a three-round Delphi study with mailed surveys, expert consensus on four dimensions of advanced-level practice that define advanced practice registered dietitians (RDs) in clinical nutrition was explored. Purposive sampling identified 117 RDs who met advanced-level practice criteria. In round 1, experts rated the essentiality of statements on a 7-point ordinal scale and generated open-ended practice activity statements regarding the following four dimensions of advanced-level practice: professional knowledge, abilities and skills, approaches to practice, roles and relationships, and practice behaviors. Median ratings of 1.0 to 3.0 were defined as essential, 4.0 was neutral, and 5.0 to 7.0 were nonessential. In rounds 2 and 3, experts re-rated statements not reaching consensus by evaluating their previous responses, group median rating, and comments. Consensus was reached when the interquartile range of responses to a statement was ≤2.0. Eighty-five experts enrolled (72.6%); 76 (89.4%) completed all rounds. In total, 233 statements were rated, with 100% achieving consensus; 211 (90.6%) were essential to advanced practice RD clinical practice. Having a master's degree; completing an advanced practice residency; research coursework; and advanced continuing education were essential, as were having 8 years of experience; clinical nutrition knowledge/expertise; specialization; participation in research activities; and skills in technology and communication. Highly essential approaches to practice were systematic yet adaptable and used critical thinking and intuition and highly essential values encompassed professional growth and service to patients. Roles emphasized patient care and leadership. Essential practice activities within the nutrition care process included provision of complex patient-centered nutrition care using application of advanced knowledge/expertise and

    On 9 June 2008, the UK's largest mass stranding event (MSE) of short-beaked common dolphins (Delphinus delphis) occurred in Falmouth Bay, Cornwall. At least 26 dolphins died, and a similar number was refloated/herded back to sea. On necropsy, all dolphins were in good nutritive status with empty stomachs and no evidence of known infectious disease or acute physical injury. Auditory tissues were grossly normal (26/26) but had microscopic haemorrhages (5/5) and mild otitis media (1/5) in the freshest cases. Five lactating adult dolphins, one immature male, and one immature female tested were free of harmful algal toxins and had low chemical pollutant levels. Pathological evidence of mud/seawater inhalation (11/26), local tide cycle, and the relative lack of renal myoglobinuria (26/26) suggested MSE onset on a rising tide between 06∶30 and 08∶21 hrs (9 June). Potential causes excluded or considered highly unlikely included infectious disease, gas/fat embolism, boat strike, by-catch, predator attack, foraging unusually close to shore, chemical or algal toxin exposure, abnormal weather/climatic conditions, and high-intensity acoustic inputs from seismic airgun arrays or natural sources (e.g., earthquakes). International naval exercises did occur in close proximity to the MSE with the most intense part of the exercises (including mid-frequency sonars) occurring four days before the MSE and resuming with helicopter exercises on the morning of the MSE. The MSE may therefore have been a “two-stage process” where a group of normally pelagic dolphins entered Falmouth Bay and, after 3–4 days in/around the Bay, a second acoustic/disturbance event occurred causing them to strand en masse. This spatial and temporal association with the MSE, previous associations between naval activities and cetacean MSEs, and an absence of other identifiable factors known to cause cetacean MSEs, indicates naval activity to be the most probable cause of the Falmouth Bay MSE.

  14. Helping someone with problem drinking: Mental health first aid guidelines - a Delphi expert consensus study

    PubMed Central

    2009-01-01

    Background Alcohol is a leading risk factor for avoidable disease burden. Research suggests that a drinker's social network can play an integral role in addressing hazardous (i.e., high-risk) or problem drinking. Often however, social networks do not have adequate mental health literacy (i.e., knowledge about mental health problems, like problem drinking, or how to treat them). This is a concern as the response that a drinker receives from their social network can have a substantial impact on their willingness to seek help. This paper describes the development of mental health first aid guidelines that inform community members on how to help someone who may have, or may be developing, a drinking problem (i.e., alcohol abuse or dependence). Methods A systematic review of the research and lay literature was conducted to develop a 285-item survey containing strategies on how to help someone who may have, or may be developing, a drinking problem. Two panels of experts (consumers/carers and clinicians) individually rated survey items, using a Delphi process. Surveys were completed online or via postal mail. Participants were 99 consumers, carers and clinicians with experience or expertise in problem drinking from Australia, Canada, Ireland, New Zealand, the United Kingdom, and the United States. Items that reached consensus on importance were retained and written into guidelines. Results The overall response rate across all three rounds was 68.7% (67.6% consumers/carers, 69.2% clinicians), with 184 first aid strategies rated as essential or important by ≥80% of panel members. The endorsed guidelines provide guidance on how to: recognize problem drinking; approach someone if there is concern about their drinking; support the person to change their drinking; respond if they are unwilling to change their drinking; facilitate professional help seeking and respond if professional help is refused; and manage an alcohol-related medical emergency. Conclusion The guidelines

  15. Expert Delphi survey on research and development into drugs for neglected diseases

    PubMed Central

    2011-01-01

    Background Tropical infectious diseases are called neglected, because they are, inter alia, characterized by an R&D deficit. A similar deficit exists for rare (orphan) diseases which neither promise a sufficient return on R&D investment. To encourage the development of treatments for rare diseases, orphan drug acts were created which contain financial and non-financial incentives for the pharmaceutical industry. Similar instruments aimed exclusively at neglected diseases do not yet exist. Proposals for a regulatory approach to promote R&D for neglected diseases include the application of selected orphan drug incentives, or the implementation of a Medical Research and Development Treaty (MRDT) with national funding obligations for medical R&D. We compiled and analyzed experts' opinions on causes for the treatment deficit for neglected diseases and on desirable and feasible measures to promote neglected disease R&D. Hereby, the focus was on mechanisms contained in orphan drug regulations and in the Medical Research and Development Treaty draft (Discussion draft 4, 2005). Lastly, we solicited experts' opinions on the desirability and feasibility of a regulatory instrument to foster R&D for neglected diseases. Methods An international online-Delphi survey was conducted with 117 (first round) and 56 (second round) experts of different professional backgrounds and professional affiliations who formulated and ranked causes and solutions related to the treatment deficit for neglected diseases. Results In both rounds of survey, the majority of the participating experts (88.4% first round, 86.8% second round) advocated the development of a regulatory instrument to promote R&D for neglected diseases. Most experts (77.9% first round, 79.3% second round) also considered this to be a feasible option. With the exception of market exclusivity, which was viewed critically, key provisions contained in orphan drug regulations were judged favorably also for neglected diseases. A

    2013-01-01

    Background Demographical changes have stimulated a coordination reform in the Norwegian health care sector, creating new working practices and extending coordination within and between primary and hospital care, increasing the need for inter-municipal cooperation (IMC). This study aimed to identify challenges to coordination and IMC in the Norwegian health care sector as a basis for further theorizing and managerial advice in this growing area of research and practice. Methods A Delphi study of consensus development was used. Experts in coordination and IMC in health care services were selected by the healthcare manager or the councillor in their respective municipalities. In the first round, an expert panel received open-ended questions addressing possible challenges, and their answers were categorized and consolidated as the basis for further validation in the second round. The expert panel members were then asked to point out important statements in the third round, before the most important statements ranked by a majority of the members were rated again in the fourth round, including the option to explain the ratings. The same procedure was used in round five, with the exception that the expert panel members could view the consolidated results of their previous rankings as the basis for a new and final rating. The statements reaching consensus in round five were abstracted and themed. Results Nineteen experts consented to participate. Nine experts (47%) completed all of the five rounds. Eight statements concerning coordination reached consensus, resulting in four themes covering these challenges: different culture, uneven balance of power, lack of the possibility to communicate electronically, and demanding tasks in relation to resources. Three statements regarding challenges to IMC reached consensus, resulting in following themes: coopetition, complex leadership, and resistance to change. Conclusions This study identified several important challenges for

    2014-01-01

    Background Undertaking a Delphi exercise is recommended during the second stage in the development process for a reporting guideline. To continue the development for the Guideline for Reporting Evidence-based practice Educational interventions and Teaching (GREET) a Delphi survey was undertaken to determine the consensus opinion of researchers, journal editors and educators in evidence-based practice (EBP) regarding the information items that should be reported when describing an educational intervention for EBP. Methods A four round online Delphi survey was conducted from October 2012 to March 2013. The Delphi panel comprised international researchers, educators and journal editors in EBP. Commencing with an open-ended question, participants were invited to volunteer information considered important when reporting educational interventions for EBP. Over three subsequent rounds participants were invited to rate the importance of each of the Delphi items using an 11 point Likert rating scale (low 0 to 4, moderate 5 to 6, high 7 to 8 and very high >8). Consensus agreement was set a priori as at least 80 per cent participant agreement. Consensus agreement was initially calculated within the four categories of importance (low to very high), prior to these four categories being merged into two (<7 and ≥7). Descriptive statistics for each item were computed including the mean Likert scores, standard deviation (SD), range and median participant scores. Mean absolute deviation from the median (MAD-M) was also calculated as a measure of participant disagreement. Results Thirty-six experts agreed to participate and 27 (79%) participants completed all four rounds. A total of 76 information items were generated across the four survey rounds. Thirty-nine items (51%) were specific to describing the intervention (as opposed to other elements of study design) and consensus agreement was achieved for two of these items (5%).

    Kantz, Jeannine Wells

    The primary purpose of this research was to develop a model for a professional science master's program combining biotechnology and business. The objectives were to identify stakeholder preferences for various dimensions of a professional science master's program combining biotechnology and business and to identify differences in priorities between subgroups. A secondary purpose was to examine user preferences between Web-based and traditional methods of conducting a Delphi study and the panelist's impressions of its usefulness for program development. Prior to the first round, demographic data were collected on panelists regarding their gender, age, years experience in their current field, position title and education levels. Round 1 started with eight open-ended questions designed to investigate (a) learning objectives, (b) internships, (c) thesis vs. non-thesis degrees, (d) program focus (e) possible entry level positions, (f) roles for the industry advisory board, (g) recommended hours of hands-on experience and (h) other issues of importance. The final round ended with three questions to assess the panelists' perception of the usefulness of the Delphi for program development in higher education. Twenty-four panelists started Round 1 and participation in subsequent rounds varied from 17 in Round 2 to 11 in Round 4. Education level varied and included all levels of education in science and business. Issues emerged early in the study regarding development of different program tracks and the program goals, which were clarified in subsequent rounds. Significant differences occurred between industry and academic subgroups for two tracks, six skills designated for tracks, method of evaluating the internship, and entry-level positions appropriate for new graduates. When analyzed by level of confidence (high confidence vs. low confidence), significant differences occurred for (a) the number of semesters of hands-on experience students should have upon graduation, (b

    Within the GEOTECHNOLOGIEN funding scheme for geological CO2 storage by the Federal Ministry of Education and Research (BMBF) in Germany 33 projects (135 subprojects) have been funded with a total budget of 58 Mio € (excluding industry funds) from 2005 to 2014. In 2012, the German parliament passed the transposition of the EU CCS Directive 2009/31/EG into the national "Carbon Dioxide Storage Law" (KSpG). Annex 1 of the KSpG provides a description of criteria for the characterization and assessment of a potential CO2 storage site. Annex 2 describes the expected monitoring system of a CO2 storage site. The criteria given in the appendices are of general nature, which reflects (1) that the CO2 storage technology is still being developed and (2) that site specific aspects needs to be considered. In 2012 an umbrella project called AUGE has been launched in order to compile and summarize the results of the GEOTECHNOLOGIEN projects to underpin the two Annexes scientifically. By integration of the individual project results AUGE aims at derive recommendations for the review and implementation of the KSpG. The recommendations shall be drafted based on a common ground of science, public authorities and industry. Therefore, the AUGE project includes a Delphi expert process as an essential part. It is realized in cooperation with the company COMPARE Consulting, Göppingen. The implementation of the Delphi-Process is organized in three steps: • After the technical preparation of a standardized questionnaire (2014/2015) it was sent to 129 experts from science, industry and public authorities in Germany. After a few weeks of consideration time, 40 persons (30 %) had decided to participate actively in this inquiry. • Following the results of the first interrogation campaign, the second survey campaign started at the end of 2015. The same list of questions was used, complemented with the results of the first inquiry campaign. The intention is reduce the variance of the

    The relative weighting on traits within breeding goals are generally determined by bio-economic models or profit functions. While such methods have generally delivered profitability gains to producers, and are being expanded to consider non-market values, current approaches generally do not consider the numerous and diverse stakeholders that affect, or are affected, by such tools. Based on principles of respondent anonymity, iteration, controlled feedback and statistical aggregation of feedback, a Delphi study was undertaken to gauge stakeholder opinion of the importance of detailed milk quality traits within an overall dairy breeding goal for profit, with the aim of assessing its suitability as a complementary, participatory approach to defining breeding goals. The questionnaires used over two survey rounds asked stakeholders: (a) their opinion on incorporating an explicit sub-index for milk quality into a national breeding goal; (b) the importance they would assign to a pre-determined list of milk quality traits and (c) the (relative) weighting they would give such a milk quality sub-index. Results from the survey highlighted a good degree of consensus among stakeholders on the issues raised. Similarly, revelation of the underlying assumptions and knowledge used by stakeholders to make their judgements illustrated their ability to consider a range of perspectives when evaluating traits, and to reconsider their answers based on the responses and rationales given by others, which demonstrated social learning. Finally, while the relative importance assigned by stakeholders in the Delphi survey (4% to 10%) and the results of calculations based on selection index theory of the relative emphasis that should be placed on milk quality to halt any deterioration (16%) are broadly in line, the difference indicates the benefit of considering more than one approach to determining breeding goals. This study thus illustrates the role of the Delphi technique, as a complementary

    Thirty specialists in humanitarian work supporting the care and protection of children in crisis settings completed a 3-phase Delphi consultation. Proposals of best practice were elicited, reviewed, and rated by participants. A high level of consensus support was reached for 55 statements. These statements emphasized utilization of existing resources, participation, and inclusivity. The influences of resilience theory, social ecology, and cultural sensitivity were clearly evident. The utilization of developmental theory could be strengthened in relation to more differentiated understanding of the operation of protective influences and conceptualization of such influences in terms of "adaptive systems." Wider research engagement by development scientists in diverse cultural settings and clear formulation of findings for practitioners and policy makers would further support evidence-based humanitarian practice.

    Inclusive J/psi production in photon-photon collisions has been observed by the DELPHI collaboration at LEP II beam energies. A clean signal from the reaction gamma][gamma [right arrow] J/psi + X is seen. Number of observed events, N(J/psi [right arrow] mu]+[mu-) = 36 plus-or-minus 7 for the integrated luminosity 617 pb-1, yielding a cross section of sigma](J/[psi [right arrow] mu]+[mu-) = 25.2 plus-or-minus 10.2 pb. Based on a study of the event shapes of different types of gamma][gamma processes in the PYTHIA program, we conclude that (74plus-or-minus22)% of the observed J/psi events are due to the 'resolved' photons, the dominant contribution of which is evidently a single color-octet gluon within the photon.

    Polypharmacy and inappropriate medication use among older adults contribute to adverse drug reactions, falls, cognitive impairment, noncompliance, hospitalization and mortality. While deprescribing - tapering, reducing or stopping a medication - is feasible and relatively safe, clinicians find it difficult to carry out. Deprescribing guidelines would facilitate this process. The aim of this paper is to identify and prioritize medication classes where evidence-based deprescribing guidelines would be of benefit to clinicians. A modified Delphi approach included a literature review to identify potentially inappropriate medications for the elderly, an expert panel to develop survey content and three survey rounds to seek consensus on priorities. Panel participants included three pharmacists, two family physicians and one social scientist. Sixty-five Canadian geriatrics experts (36 pharmacists, 19 physicians and 10 nurse practitioners) participated in the survey. Twenty-nine drugs/drug classes were included in the first survey with 14 reaching the required (≥ 70%) level of consensus, and 2 new drug classes added from qualitative comments. Fifty-three participants completed round two, and 47 participants completed round three. The final five priorities were benzodiazepines, atypical antipsychotics, statins, tricyclic antidepressants, and proton pump inhibitors; nine other drug classes were also identified as being in need of evidence-based deprescribing guidelines. The Delphi consensus process identified five priority drug classes for which expert clinicians felt guidance is needed for deprescribing. The classes of drugs that emerged strongly from the rankings dealt with mental health, cardiovascular, gastroenterological, and neurological conditions. The results suggest that deprescribing and overtreatment occurs through the full spectrum of primary care, and that evidence-based deprescribing guidelines are a priority in the care of the elderly.

    A two-part Delphi Survey was given to transportation experts attending the Asilomar Conference on Transportation and Energy in August, 2011. The survey asked respondents about trends in the US transportation sector in 2030. Topics included: alternative vehicles, high speed rail construction, rail freight transportation, average vehicle miles traveled, truck versus passenger car shares, vehicle fuel economy, and biofuels in different modes. The survey consisted of two rounds -- both asked the same set of seven questions. In the first round, respondents were given a short introductory paragraph about the topic and asked to use their own judgment in their responses. In the second round, the respondents were asked the same questions, but were also given results from the first round as guidance. The survey was sponsored by Argonne National Lab (ANL), the National Renewable Energy Lab (NREL), and implemented by University of California at Davis, Institute of Transportation Studies. The survey was part of the larger Transportation Energy Futures (TEF) project run by the Department of Energy, Office of Energy Efficiency and Renewable Energy. Of the 206 invitation letters sent, 94 answered all questions in the first round (105 answered at least one question), and 23 of those answered all questions in the second round. 10 of the 23 second round responses were at a discussion section at Asilomar, while the remaining were online. Means and standard deviations of responses from Round One and Two are given in Table 1 below. One main purpose of Delphi surveys is to reduce the variance in opinions through successive rounds of questioning. As shown in Table 1, the standard deviations of 25 of the 30 individual sub-questions decreased between Round One and Round Two, but the decrease was slight in most cases.

    Changes in forest landscapes resulting from road construction have increased remarkably in the last few years. On the other hand, the sustainable management of forest resources can only be achieved through a well-organized road network. In order to minimize the environmental impacts of forest roads, forest road managers must design the road network efficiently and environmentally as well. Efficient planning methodologies can assist forest road managers in considering the technical, economic, and environmental factors that affect forest road planning. This paper describes a three-stage methodology using the Delphi method for selecting the important criteria, the Analytic Hierarchy Process for obtaining the relative importance of the criteria, and finally, a spatial multi-criteria evaluation in a geographic information system (GIS) environment for identifying the lowest-impact road network alternative. Results of the Delphi method revealed that ground slope, lithology, distance from stream network, distance from faults, landslide susceptibility, erosion susceptibility, geology, and soil texture are the most important criteria for forest road planning in the study area. The suitability map for road planning was then obtained by combining the fuzzy map layers of these criteria with respect to their weights. Nine road network alternatives were designed using PEGGER, an ArcView GIS extension, and finally, their values were extracted from the suitability map. Results showed that the methodology was useful for identifying road that met environmental and cost considerations. Based on this work, we suggest future work in forest road planning using multi-criteria evaluation and decision making be considered in other regions and that the road planning criteria identified in this study may be useful.

  12. Mental Health First Aid guidelines for helping a suicidal person: a Delphi consensus study in the Philippines

    PubMed Central

    2010-01-01

    Background This study aimed to develop guidelines for how a member of the Filipino public should provide mental health first aid to a person who is suicidal. Methods The guidelines were produced by developing a questionnaire containing possible first aid actions and asking an expert panel of 34 Filipino mental health clinicians to rate whether each action should be included in the guidelines. The content of the questionnaire was based on a systematic search of the relevant evidence and claims made by authors of consumer and carer guides and websites. The panel members were asked to complete the questionnaire by web survey. Three rounds of the rating were carried and, at the end of each round, items that reached the consensus criterion were selected for inclusion in the guidelines. During the first round, panel members were also asked to suggest any additional actions that were not covered in the original questionnaire (to include items that are relevant to local cultural circumstances, values, and social norms). Responses to these open-ended questions were used to generate new items. Results The output from the Delphi process was a set of agreed upon action statements. The Delphi process started with 138 statements, 48 new items were written based on suggestions from panel members and, of these 186 items, 102 met the consensus criterion. These statements were used to develop the guidelines appended to this paper. The guidelines are currently being translated into local languages. Conclusions There are a number of actions that are considered to be useful for members of the public when they encounter someone who is experiencing suicidal thoughts or engaging in suicidal behaviour. Although the guidelines are designed for members of the public, they may also be helpful to non-mental health professionals working in health and welfare settings. PMID:21167076

    Objectives To identify and rank the most significant workplace stressors to which consultants and trainees are exposed within the publicly funded health sector in Ireland. Design Following a preliminary semistructured telephone interview, a Delphi technique with 3 rounds of reiterative questionnaires was used to obtain consensus. Conducted in Spring 2014, doctors were purposively selected by their college faculty or specialty training body. Setting Consultants and higher specialist trainees who were engaged at a collegiate level with their faculty or professional training body. All were employed in the Irish publicly funded health sector by the Health Services Executive. Participants 49 doctors: 30 consultants (13 male, 17 female) and 19 trainees (7 male, 12 female). Consultants and trainees were from a wide range of hospital specialties including anaesthetics, radiology and psychiatry. Results Consultants are most concerned with the quality of healthcare management and its impact on service. They are also concerned about the quality of care they provide. They feel undervalued within the negative sociocultural environment that they work. Trainees also feel undervalued with an uncertain future and they also perceive their sociocultural environment as negative. They echo concerns regarding the quality of care they provide. They struggle with the interface between career demands and personal life. Conclusions This Delphi study sought to explore the working life of doctors in Irish hospitals at a time when resources are scarce. It identified both common and distinct concerns regarding sources of stress for 2 groups of doctors. Its identification of key stressors should guide managers and clinicians towards solutions for improving the quality of patient care and the health of care providers. PMID:26700286

    Purpose. The purpose of this study was to identify new or emerging technological trends and events that are likely to occur between now and 2017 that will have an impact on the commercial aviation maintenance, repair, and overhaul (MRO) industry. Further, it was the purpose of this study to examine those technological trends and events believed to provide the greatest impact and, given the experts' analysis, identify the feasibility of implementation. Methodology. This descriptive study utilized the Delphi method with a panel of twenty-four experts comprised of practitioners, theorists, and futurists. A priority matrix was utilized to determine the impact and feasibility of trend and events. Findings. The experts identified fifty-three trends and events that will impact the commercial aviation maintenance, repair, and overhaul (MRO) industry. Analysis of the priority matrix revealed eighteen trends and events were of high priority and high feasibility. Conclusions. The responses from the expert panel were examined and the findings analyzed. The following are the conclusions constructed from the data provided by the Delphi panel of experts: (1) the need to respond to the demands of the maintenance, repair, and overhaul (MRO) industry such as down time, efficiency, cost, and environmental concerns by implementing new technology, (2) the demand to integrate and implement new technology as indicative of the priority matrix scoring high importance/high feasibility, (3) to proactively address the inadequate professional development in new technologies, and (4) the consensus reached by the panel of experts of importance and feasibility of implementation of new technologies encompass eighteen trends and events. Implications and recommendations for action. The implementation of new and emerging technological advances in the commercial aviation maintenance, repair, and overhaul (MRO) industry between now and 2017 will be dependent on the technologies' capacity to reduce

    2010-01-01

    Background Problems with substance use are common in some Aboriginal communities. Although problems with substance use are associated with significant mortality and morbidity, many people who experience them do not seek help. Training in mental health first aid has been shown to be effective in increasing knowledge of symptoms and behaviours associated with seeking help. The current study aimed to develop culturally appropriate guidelines for providing mental health first aid to an Aboriginal or Torres Strait Islander person who is experiencing problem drinking or problem drug use (e.g. abuse or dependence). Methods Twenty-eight Aboriginal health experts participated in two independent Delphi studies (n = 22 problem drinking study, n = 21 problem drug use; 15 participated in both). Panellists were presented with statements about possible first aid actions via online questionnaires and were encouraged to suggest additional actions not covered by the content. Statements were accepted for inclusion in the guidelines if they were endorsed by ≥ 90% of panellists as either 'Essential' or 'Important'. At the end of the two Delphi studies, participants were asked to give feedback on the value of the project and their participation experience. Results From a total of 735 statements presented over two studies, 429 were endorsed (223 problem drinking, 206 problem drug use). Statements were grouped into sections based on common themes (n = 7 problem drinking, n = 8 problem drug use), then written into guideline documents. Participants evaluated the Delphi method employed, and the guidelines developed, as useful and appropriate for Aboriginal and Torres Strait Islander people. Conclusions Aboriginal health experts were able to reach consensus about culturally appropriate first aid for problems with substance use. Many first aid actions endorsed in the current studies were not endorsed in previous international Delphi studies, conducted on problem drinking and problem drug use

    Access to clean water is a grand challenge in the 21st century. Water safety testing for pathogens currently depends on surrogate measures such as fecal indicator bacteria (e.g., E. coli). Metagenomics concerns high-throughput, culture-independent, unbiased shotgun sequencing of DNA from environmental samples that might transform water safety by detecting waterborne pathogens directly instead of their surrogates. Yet emerging innovations such as metagenomics are often fiercely contested. Innovations are subject to shaping/construction not only by technology but also social systems/values in which they are embedded, such as experts' attitudes towards new scientific evidence. We conducted a classic three-round Delphi survey, comprised of 107 questions. A multidisciplinary expert panel (n = 24) representing the continuum of discovery scientists and policymakers evaluated the emergence of metagenomics tests. To the best of our knowledge, we report here the first Delphi foresight study of experts' attitudes on (1) the top 10 priority evidentiary criteria for adoption of metagenomics tests for water safety, (2) the specific issues critical to governance of metagenomics innovation trajectory where there is consensus or dissensus among experts, (3) the anticipated time lapse from discovery to practice of metagenomics tests, and (4) the role and timing of public engagement in development of metagenomics tests. The ability of a test to distinguish between harmful and benign waterborne organisms, analytical/clinical sensitivity, and reproducibility were the top three evidentiary criteria for adoption of metagenomics. Experts agree that metagenomic testing will provide novel information but there is dissensus on whether metagenomics will replace the current water safety testing methods or impact the public health end points (e.g., reduction in boil water advisories). Interestingly, experts view the publics relevant in a "downstream capacity" for adoption of metagenomics rather

    2015-01-01

    Objectives: In many countries including the United Kingdom, hearing aids are a first line of audiologic intervention for many people with tinnitus and aidable hearing loss. Nevertheless, there is a lack of high quality evidence to support that they are of benefit for tinnitus, and wide variability in their use in clinical practice especially for people with mild hearing loss. The aim of this study was to identify a consensus among a sample of UK clinicians on the criteria for hearing aid candidature and clinical practice in fitting hearing aids specifically for mild hearing loss with and without tinnitus. This will allow professionals to establish clinical benchmarks and to gauge their practice with that used elsewhere. Design: The Delphi technique, a systematic methodology that seeks consensus amongst experts through consultation using a series of iterative questionnaires, was used. A three-round Delphi survey explored clinical consensus among a panel of 29 UK hearing professionals. The authors measured panel agreement on 115 statements covering: (i) general factors affecting the decision to fit hearing aids, (ii) protocol-driven factors affecting the decision to fit hearing aids, (iii) general practice, and (iv) clinical observations. Consensus was defined as a priori ≥70% agreement across the panel. Results: Consensus was reached for 58 of the 115 statements. The broad areas of consensus were around factors important to consider when fitting hearing aids; hearing aid technology/features offered; and important clinical assessment to verify hearing aid fit (agreement of 70% or more). For patients with mild hearing loss, the greatest priority was given by clinicians to patient-centered criteria for fitting hearing aids: hearing difficulties, motivation to wear hearing aids, and impact of hearing loss on quality of life (chosen as top five by at least 64% of panelists). Objective measures were given a lower priority: degree of hearing loss and shape of the

    Background Dermatology is a minor module in internal medicine undergraduate curriculum. Limited time is allocated for its teaching. Most graduates are inadequately prepared to diagnose and manage skin diseases. We aimed to identify the core content of a more effective dermatology module. Methods A modified Delphi method was used to reach a consensus. A questionnaire was developed by a selected panel and sent to 20 dermatologists, family physicians and general practitioners (GPs), respectively. They were asked to rate diseases according to importance. The participants then answered the questionnaire again with results of the first round made available to them. The final module content was identified based on the panel’s collective opinions. Results Eleven topics had mode and median values of 1 with an agreement level of more than 70%. They were as follows: (1) skin structure and function; (2) infections and infestations; (3) the skin in systemic diseases; (4) dermatology emergencies; (5) drug eruptions; (6) psoriasis; (7) eczema; (8) sexually transmitted infections; (9) leprosy; (10) acne; and (11) clinical skills and diagnostic procedures. A total of 56 diseases were identified as important. Conclusion Results of this study reflect the importance of understanding the influence of regional factors on common and important skin diseases. These topics may be used to develop a more effective dermatology module for the Malaysian undergraduate medical curriculum. PMID:27418873

    [Purpose] The aim of this study was to clarify essential abilities of novice physical and occupational therapists for independent execution of their duties and to develop a clinical competence assessment tool. [Subjects] Forty-five experienced therapists participated in this study. [Methods] A two-phase mixed-methods design was used. First, semi structured interviews were conducted on 15 experienced therapists to create a comprehensive list of essential abilities that novice therapists need. Second, 30 experienced therapists participated in a two-round Delphi study to select items for the assessment tool being developed. [Results] Fifty-five items were extracted and classified into three categories: basic attitudes, therapeutic skills, and clinical practice-related thoughts. [Conclusion] Present results suggest that not only knowledge of execution of therapy-related duties and therapeutic skills is essential in novice therapist, but also appropriate abilities in social adjustment, self-management, and self-education. The newly developed tool might be useful for postgraduate education in clinical practice. PMID:27134395

    Zoonotic diseases have a significant impact on public health globally. To prevent or reduce future zoonotic outbreaks, there is a constant need to invest in research and surveillance programs while updating risk management strategies. However, given the limited resources available, disease prioritization based on the need for their control and surveillance is important. This study was performed to identify and weight disease criteria for the prioritization of zoonotic diseases in Switzerland using a semi-quantitative research method based on expert opinion. Twenty-eight criteria relevant for disease control and surveillance, classified under five domains, were selected following a thorough literature review, and these were evaluated and weighted by seven experts from the Swiss Federal Veterinary Office using a modified Delphi panel. The median scores assigned to each criterion were then used to rank 16 notifiable and/or emerging zoonoses in Switzerland. The experts weighted the majority of the criteria similarly, and the top three criteria were Severity of disease in humans, incidence and prevalence of the disease in humans and treatment in humans. Based on these weightings, the three highest ranked diseases were Avian Influenza, Bovine Spongiform Encephalitis, and Bovine Tuberculosis. Overall, this study provided a preliminary list of criteria relevant for disease prioritization in Switzerland. These were further evaluated in a companion study which involved a quantitative prioritization method and multiple stakeholders. PMID:26036342

    Consumer involvement in NHS research is Department of Health policy within the UK. Despite the existence of policy directives and guidance, until recently there has been no consensus among consumers and researchers about what it means to involve consumers successfully in NHS research. This paper discusses the value of consensus research in this policy area, and presents the detailed findings of a Delphi study carried out to reach consensus on principles and indicators of successful consumer involvement in NHS research. Study participants, comprising consumers, researchers and consumer-researchers, were identified using a purposive sampling strategy. Consensus was reached on eight clear and valid principles of successful consumer involvement in NHS research, with each principle having at least one clear and valid indicator. Subgroup analysis revealed few significant differences in how consumers, researchers and consumer-researchers rated the principles and indicators. The implications and limitations of the study are discussed. Further research is needed to assess: (1) the usefulness of the principles and indicators for differing models of consumer involvement, health research methodologies, and subject areas within health research; and (2) the impact of 'successful' consumer involvement on health research processes and outcomes.

    Cultural awareness is a key issue in healthcare worldwide. Valid and reliable assessments are needed to assess cultural awareness for occupational therapy students. The purpose of this study was to develop a scale to assess cultural awareness for Latin American occupational therapy students. A Delphi design was implemented considering four rounds with experts from four countries. A 30-item scale in Spanish was developed to assess three categories of items: personal, therapeutic strategies and persons' cultures. The experts highlighted local features for professional practice as a key aspect of the scale. Local differences in practice were considered with the profession's traditions and prevailing knowledge across the scale. A participatory strategy and an international group of experts enriched the cultural relevance. A subsequent study of statistical reliability is required (the scale is not presented in an extended version here). Further research should consider the application of the scale and strategies to improve cultural awareness across the curricula. Copyright © 2016 John Wiley & Sons, Ltd. PMID:26800344

    Background: Members of the general public often lack the knowledge and skills to intervene effectively to help someone who may be developing a psychotic illness before appropriate professional help is received. Methods: We used the Delphi method to determine recommendations on first aid for psychosis. An international panel of 157 mental health consumers, carers, and clinicians completed a 146-item questionnaire about how a member of the public could help someone who may be experiencing psychosis. The panel members rated each questionnaire item according to whether they believed the statement should be included in the first aid recommendations. The results were analyzed by comparing consensus rates across the 3 groups. Three rounds of ratings were required to consolidate consensus levels. Results: Eighty-nine items were endorsed by ≥80% of panel members from all 3 groups as essential or important for psychosis first aid. These items were grouped under the following 9 headings: how to know if someone is experiencing psychosis; how to approach someone who may be experiencing psychosis; how to be supportive; how to deal with delusions and hallucinations; how to deal with communication difficulties; whether to encourage the person to seek professional help; what to do if the person does not want help; what to do in a crisis situation when the person has become acutely unwell; what to do if the person becomes aggressive. Conclusions: These recommendations will improve the provision of first aid to individuals who are developing a psychotic disorder by informing the content of training courses. PMID:17768307

    Context: Athletic training has expanded from traditional sport-team settings to varied settings involving active populations. Athletic trainers also use their education and abilities in administration to take on roles of management in hospitals and health care clinics. Objective: To begin to explore the knowledge, skills, and abilities needed in the emerging practice setting of health care management. Design: Delphi study. Setting: Directed surveys. Patients or Other Participants: Eight athletic trainers working as hospital and health care clinic managers in varied geographic settings. Data Collection and Analysis: Three rounds of directed surveys were used and included (1) a series of demographic questions and 1 focused, open-ended question, (2) 32 statements scored on a 6-point Likert-type scale with no neutral statement, and (3) 10 statements ranked in order of importance for the athletic trainer working as a health care manager. Results: I grouped the results into 2 categories: leadership skills and management tools. Conclusions: According to participants, effective health care managers need a strong understanding of business and management tools along with more interpersonal skills in communication and leadership. The results are consistent with the literature and may be applied in athletic training education programs and by athletic trainers seeking health care management positions. PMID:23672329

    Introduction: The “Comprehensive ICF Core Set for Chronic Obstructive Pulmonary Diseases (COPD)“ is an application of the International Classification of Functioning, Disability and Health (ICF) and represents the typical spectrum of problems in functioning of patients with COPD. The objective of this study was to validate this ICF Core Set from the perspective of physicians. Materials and Methodology: Physicians experienced in COPD treatment were asked about the patients’ problems treated by physicians in patients with COPD in a three-round electronic mail survey using the Delphi technique. Responses were linked to the ICF. Results: Seventy-six physicians in 44 countries gave a total of 1330 responses that were linked to 148 different ICF categories. Nine ICF categories were not represented in the Comprehensive ICF Core Set for COPD although at least 75% of the participants have rated them as important. Nineteen concepts were linked to the not yet developed ICF component personal factors and seventeen concepts were not covered by the ICF. Conclusion: The high percentage of ICF categories represented in the ICF Core Set for COPD indicates satisfactory content validity from the perspective of the physicians. However, some issues were raised that were not covered and need to be investigated further. PMID:23730367

    This study explored science-specific strategies and materials that might be effective components in a Response to Intervention (RTI) science tutorial model for at-risk, academically unsuccessful students in grades 4 -- 8. Through an iterative Delphi process of responding to three rounds of questionnaires, a nationwide panel of 63 experts in the field of science education identified and came to consensus on 44 effective strategies and six instructional materials and types of equipment for supplemental instruction in science, resulting in a three tier RTI tutorial model. This model provides an initial guide for science educators in applicable practices for each tier of the RTI framework, and was developed to assist administrators, program managers, and science educators in developing effective, systemic RTI instructional programming for science education in grades 4 -- 8, and may provide an additional planning tool in determining evidence-based practices that may lead to achievement for at-risk, academically unsuccessful students in grades 4 -- 8. Future research on specific intervention strategies within science and their effects on science achievement are needed, as well as a further examination to test the efficacy of the model on rates of science achievement for at-risk, academically unsuccessful students.

    As students begin middle school, they are expected to possess and apply a wide array of nonfiction reading strategies if they are to comprehend new concepts from nonfiction texts. Although strategies and resource guides for fiction reading are available, an effective nonfiction reading comprehension resource guide tailored to middle school science teachers is lacking. The conceptual framework guiding this study is based on schema theory that supports the use of prior knowledge as a foundation for learning. The purpose of this project study was to address this local problem by providing middle school science teachers with a user-friendly resource for nonfiction reading comprehension strategies in a science context. The research question examined nonfiction reading comprehension strategies that could supplement middle school science teachers' instructional practices to increase student comprehension in science, as reflected on the results of state standardized tests. This project study consulted science and language arts teachers using a Delphi questionnaire technique to achieve a consensus through multiple iterations of questionnaires. Science teachers identified 7 areas of concern as students read nonfiction texts, and language arts teachers suggested effective reading comprehension strategies to address these areas. Based on the consensus of reading comprehension strategies and review of literature, a resource guide for middle school science teachers was created. By improving reading comprehension in content areas, teachers may not only increase student learning, but also underscore the importance of literacy relating to life-long learning through future occupations, academic endeavors, and society as well.

    Keeping an exact calendar was important to schedule Delphic festivals. The proper day for a prophecy involved a meticulous calculation, which was carried out by learned priests and ancient philosophers. The month of Bysios on average is February, but in reality it could be any 30-day interval between January and March. Bysios starts with a New Moon, but the beginning of the month is not easily pinpointed and thus Bysios and the 7th day for giving an oracle cannot be identified according to the Gregorian calendar. The celestial motions of Lyra and Cygnus with regards to sunrise and sunset are related to the Delphi temple's orientation and the high altitude of steep cliffs of the Faidriades in front of it. Light from the rising Sun shines at the back of the temple where the statue of the god is located, while the appearance and disappearance of Lyra and Cygnus, two of Apollo's favorite constellations in the Delphic sky, mark the period of absence of the god to the Hyperboreans. This coincides with the 3-month interval from the end of December to the middle of March. During the later part of this period, on the 7th day of Bysios, the oracle was given. At any rate, the Delphic calendar was a lunar-solar-stellar one, and was properly adjusted to coincide with and preserve the seasonal movements of those constellations.

    Tree inventories are expensive to conduct and update, so every inventory carried out must be maximized. However, increasing the number of constituent parameters increases the cost of performing and updating the inventory, illustrating the need for careful parameter selection. This article reports the results of a systematic expert rating of tree inventories aiming to quantify the relative importance of each parameter. Using the Delphi method, panels comprising city officials, arborists, and academics rated a total of 148 parameters. The total mean score, the top ranking parameters, which can serve as a guide for decision-making at practical level and for standardization of tree inventories, were: Scientific name of the tree species and genera, Vitality, Coordinates, Hazard class, and Identification number. The study also examined whether the different responsibilities and usage of urban tree databases among organizations and people engaged in urban tree inventories affected their prioritization. The results revealed noticeable dissimilarities in the ranking of parameters between the panels, underlining the need for collaboration between the research community and those commissioning, administrating, and conducting inventories. Only by applying such a transdisciplinary approach to parameter selection can urban tree inventories be strengthened and made more relevant.

    Due to the enormous importance of electrostatics in molecular biology, calculating the electrostatic potential and corresponding energies has become a standard computational approach for the study of biomolecules and nano-objects immersed in water and salt phase or other media. However, the electrostatics of large macromolecules and macromolecular complexes, including nano-objects, may not be obtainable via explicit methods and even the standard continuum electrostatics methods may not be applicable due to high computational time and memory requirements. Here, we report further development of the parallelization scheme reported in our previous work (J Comput Chem. 2012 Sep 15; 33(24):1960–6.) to include parallelization of the molecular surface and energy calculations components of the algorithm. The parallelization scheme utilizes different approaches such as space domain parallelization, algorithmic parallelization, multi-threading, and task scheduling, depending on the quantity being calculated. This allows for efficient use of the computing resources of the corresponding computer cluster. The parallelization scheme is implemented in the popular software DelPhi and results in speedup of several folds. As a demonstration of the efficiency and capability of this methodology, the electrostatic potential and electric field distributions are calculated for the bovine mitochondrial supercomplex illustrating their complex topology which cannot be obtained by modeling the supercomplex components alone.

    The aim of this study was to identify the information about commonly prescribed drugs that junior doctors should know in order to prescribe rationally in daily practice, defined as essential drug knowledge (EDK). A two-round Internet Delphi study was carried out involving general practitioners from one practice cluster, and registrars and consultants from two Dutch academic and eight teaching hospitals. A preliminary list of 377 potential EDK items for three commonly prescribed drugs was assessed on a dichotomous scale; an item was considered EDK if at least 80% consensus was reached. The consensus list of EDK items was discussed by the research team to identify similarities between the three drugs, with a view to forming a list of general EDK items applicable to other commonly prescribed drugs. Sixty experts considered 93 of the 377 items (25%) as EDK. These items were then used to form a list of 10 general EDK items. The list of EDK items identified by primary and secondary care doctors could be used in medical curricula and training programmes and for assessing the prescribing competence of future junior doctors. Further research is needed to evaluate the generalizability of this list for other commonly prescribed drugs. PMID:26506082

    ABSTRACT Purpose: To develop and evaluate a preliminary clinical decision-making tool (CDMT) to assist physiotherapists in titrating oxygen for acutely ill adults in Ontario. Methods: A panel of 14 experienced cardiorespiratory physiotherapists was recruited. Factors relating to oxygen titration were identified using a modified Delphi technique. Four rounds of questionnaires were conducted, during which the goals were to (1) generate factors, (2) reduce factors and debate contentious factors, (3) finalize factors and develop the preliminary CDMT, and (4) evaluate the usability of the tool in a clinical context. Results: The panel reached consensus on a total of 89 factors, which were compiled to create the preliminary CDMT. The global tool reached consensus for sensibility, receiving a mean score of 6/7 on a 7-point Likert-type scale (1=unacceptable; 7=excellent). Five of the nine individual components of evaluation of the tool achieved scores ≥6.0; the remaining four had mean scores between 5.4 and 5.9. Conclusion: This study produced a preliminary CDMT for oxygen titration, which the panel agreed was highly comprehensible and globally sensible. Further research is necessary to evaluate the sensibility and applicability of the tool in a clinical setting. PMID:25125782

    Many molecular events are associated with small or large conformational changes occurring in the corresponding proteins. Modeling such changes is a challenge and requires significant amount of computing time. From point of view of electrostatics, these changes can be viewed as a reorganization of local charges and dipoles in response to the changes of the electrostatic field, if the cause is insertion or deletion of a charged amino acid. Here we report a large scale investigation of modeling the changes of the folding energy due to single mutations involving charged group. This allows the changes of the folding energy to be considered mostly electrostatics in origin and to be calculated with DelPhi assigning residue-specific value of the internal dielectric constant of protein. The predicted energy changes are benchmarked against experimentally measured changes of the folding energy on a set of 257 single mutations. The best fit between experimental values and predicted changes is used to find out the effective value of the internal dielectric constant for each type of amino acid. The predicted folding free energy changes with the optimal, amino acid specific, dielectric constants are within RMSD=0.86 kcal/mol from experimentally measured changes. PMID:24683422

    Health resort programs have a long tradition, mainly in European countries and Japan. They rely on local resources and the physical environment, physical medicine interventions and traditional medicine to optimise functioning and health. Arguably because of the long tradition, there is only a limited number of high-quality studies that examine the effectiveness of health resort programs. Specific challenges to the evaluation of health resort programs are to randomise the holistic approach with a varying number of specific interventions but also the reliance on the effect of the physical environment. Reference standards for the planning and reporting of health resort studies would be highly beneficial. With the International Classification of Functioning Disability and Health (ICF), we now have such a standard that allows us to describe body functions and structures, activities and participation and interaction with environmental factors. A major challenge when applying the ICF in practice is its length. Therefore, the objective of this project was to identify the ICF categories most relevant for health resort programs. We conducted a consensus-building, three-round, e-mail survey using the Delphi technique. Based on the consensus of the experts, it was possible to come up with an ICF Core Set that can serve as reference standards for the indication, intervention planning and evaluation of health resort programs. This preliminary ICF Core Set should be tested in different regions and in subsets of health resort visitors with varying conditions.

    The conflicts of interest that may arise in relationships between academic researchers and industry continue to prompt controversy. The bulk of attention has focused on financial aspects of these relationships, but conflicts may also arise in the legal obligations that faculty acquire through consulting contracts. However, oversight of faculty members' consulting agreements is far less vigorous than for financial conflicts, creating the potential for faculty to knowingly or unwittingly contract away important rights and freedoms. Increased regulation could prevent this, but it is unclear what forms of oversight universities view as feasible and effective. In this article, we report on a Delphi study to evaluate several approaches for oversight of consulting agreements by medical schools. The panel was comprised of 11 senior administrators with responsibility for oversight of faculty consulting relationships. We found broad agreement among panelists regarding the importance of institutional oversight to protect universities' interests. There was strong support for two specific approaches: providing educational resources to faculty and submitting consulting agreements for institutional review. Notwithstanding the complexities of asserting authority to regulate private consulting agreements between faculty members and companies, medical school administrators reached consensus that several approaches to improving institutional oversight are feasible and useful.

    Objective This study aimed to develop a set of indicators that could be used to measure and monitor the self-management performance for chronic hepatitis B (CHB) patients on antiviral therapy in China. Methods A two-round Delphi study via e-mail correspondence was conducted, with a group of 30 Chinese experts. The Delphi questionnaire consisted of 53 indicators identified from a literature review. Experts rated and scored the importance of indicators on a five-point Likert scale. Consensus was considered to be reached if a median score in the top tertile (4-5) and ≥80% of panel ratings in the top tertile (4-5) after Round 2. The included indicators were validated with a group of 106 CHB patients. Results The response rates for the first and second rounds were 90.9% (n=30) and 86.7% (n=26), respectively. Three new indicators were suggested in the first round. 55 indicators were included in the second round after modified. 45 (81.8%) indicators achieved on the level of consensus, all of which had an inter-quartile range of 1 or below. The final set included 4 domains and 45 indicators which were well accepted and understandable by CHB patients. Conclusion This Delphi study produced a set of 45 self-management indicators for CHB patients on antiviral therapy in China. These indicators could be used to measure and monitor the patients’ self-management performance, with the goal of improving the quality of life in this population. PMID:26327606

    Background Many Thai people experiencing alcohol addiction do not seek help, and those who do often have inadequate access to treatment. There are few research studies focusing on alcohol addiction treatment in Thailand. Objective The purpose of the current study was to identify barriers to the treatment of alcohol addiction and to collect experts’ suggestions for improving treatment in Thailand. The Delphi technique was used to achieve consensual agreement among an expert panel within the field of alcohol addiction and treatment. Design Three rounds of a Delphi survey were completed by a panel of experts in alcohol addiction, including physicians, nurses, social workers, psychologists, healthcare officers, and an Alcoholics Anonymous member. The open-ended answers provided by 34 experts in the first round resulted in 60 statements, which were later grouped into three themes. After three rounds of questionnaires, 51 statements were accepted as consensus. Results Thirty-two experts participated in all three Delphi rounds. Over 80% of participants were particularly concerned about five obstacles to alcohol addiction treatment. The majority of suggestions from the expert panel were related to patients’ right to treatment and the national policy for reducing the negative effects of alcohol. According to the results of the present study, the experts suggested that the treatment of alcohol addiction should be continuous from primary care to tertiary care, and convenient pathways should be established in healthcare services. The experts would also like to increase the number of healthcare providers and improve their knowledge and skills in working with people experiencing alcohol addiction. Conclusions Equal rights to health and treatment for people experiencing alcohol addiction in Thailand require policy improvements, as well as acceptance and awareness of alcohol addiction from both the public and policymakers.

    Emerging and major infectious animal diseases can have significant international impact on social, economic and environmental level, and are being driven by various factors. Prevention and control measures should be prepared at both national and international level to mitigate these disease risks. Research to support such policy development is mostly carried out at national level and dedicated transnational research programmes are still in its infancy. This research reports on part of a process to develop a common strategic research agenda on emerging and major infectious diseases of livestock in Europe, covering a 5-15-year time span. A two round online Delphi study was conducted to explore the views of experts on issues relating to research needs on emerging infectious diseases of livestock in Europe. Drivers that may influence the incidence of emerging infectious animal diseases in both the short (next 5 years) and medium term (10-15 years) were identified. Drivers related to regulatory measures and biological science developments were thought to decrease the incidence, and socio-economic factors to increase the incidence of emerging infectious animal diseases. From the first round a list of threats to animal health was compiled and participants combined these threats with relevant drivers in the second round. Next to identifying threats to animal health, also possible mitigatory actions to reduce the negative impact of these threats were identified. Participants emphasised that interdisciplinary research is needed to understand drivers of emerging infectious animal diseases, as well as to develop prevention and control measures which are both socio-economic and technical. From this it can be concluded that interdisciplinary research combining both natural and social research themes is required. Some of the European member states research budget needs to be allocated so that effective prevention and mitigation strategies can be developed. PMID:22000288

    The ubiquitous protozoan parasites Giardia and Cryptosporidium have been detected from many species of captive and free-living wildlife, representing most mammalian orders. Twenty species of marine mammals have been reported to inhabit Galician waters and the region has one of the highest rates of stranding in Europe. Evidence from stranding, reported by-catches and sightings, suggests that the common dolphin (Delphinus delphis) is the most abundant cetacean on the Galician coast (Northwest Spain). The objective of this study was to detect and molecularly characterize isolates of Giardia and Cryptosporidium obtained from common dolphins stranded in this area. Between 2005 and 2012, sections of large intestine from 133 common dolphins stranded along the Galician coast were collected by the personnel of the Galician Stranding Network (Coordinadora para o Estudo dos Mamíferos Mariños, CEMMA). Using direct immunofluorescence antibody test (IFAT) and PCR amplification and sequencing of the SSU-rDNA, β-giardin genes and the ITS1-5.8S-ITS2 region, Giardia and Cryptosporidium were detected in 8 (6.0%) and 12 samples (9.0%), respectively. In two samples, co-infection by both parasites was observed. The molecular characterization revealed the presence of Giardia duodenalis assemblages A (genotypes A1 and A2) and B and Cryptosporidium parvum in these samples. This constitutes the first study in which the presence of Giardia and Cryptosporidium has been investigated in common dolphins on the European Atlantic coast, and it is also the first report of C. parvum in this host. Our findings indicate that these animals could act as reservoir of these waterborne parasites or could be victims of the contamination originated by anthropogenic activities. PMID:24704342

    Background It is estimated that around 4% of the population engages, or has engaged, in deliberate non-suicidal self-injury. In clinical samples, the figures rise as high as 21%. There is also evidence to suggest that these figures may be increasing. A family member or friend may suspect that a person is injuring themselves, but very few people know how to respond if this is the case. Simple first aid guidelines may help members of the public assist people to seek and receive the professional help they require to overcome self-injury. Methods This research was conducted using the Delphi methodology, a method of reaching consensus in a panel of experts. Experts recruited to the panels included 26 professionals, 16 people who had engaged in self-injurious behaviour in the past and 3 carers of people who had engaged in self-injurious behaviour in the past. Statements about providing first aid to a person engaged in self-injurious behaviour were sought from the medical and lay literature, but little was found. Panel members were asked to respond to general questions about first aid for NSSI in a variety of domains and statements were extracted from their responses. The guidelines were written using the items most consistently endorsed by the consumer and professional panels. Results Of 79 statements rated by the panels, 18 were accepted. These statements were used to develop the guidelines appended to this paper. Conclusion There are a number of actions which are considered to be useful for members of the public when they encounter someone who is engaging in deliberate, non-suicidal self-injury. These guidelines will be useful in revising curricula for mental health first aid and NSSI first aid training programs. They can also be used by members of the public who want immediate information about how to assist a person who is engaging in such behaviour. PMID:18647420

    Objectives To provide international consensus on the competencies required by healthcare professionals in order to provide specialist care for teenagers and young adults (TYA) with cancer. Design Modified e-Delphi survey. Setting International, multicentre study. Participants Experts were defined as professionals having worked in TYA cancer care for more than 12 months. They were identified through publications and professional organisations. Methods Round 1, developed from a previous qualitative study, included 87 closed-ended questions with responses on a nine-point Likert scale and further open-ended responses to identify other skills, knowledge and attitudes. Round 2 contained only items with no consensus in round 1 and suggestions of additional items of competency. Consensus was defined as a median score ranging from 7 to 9 and strength of agreement using mean absolute deviation of the median. Results A total of 179 registered to be members of the expert panel; valid responses were available from 158 (88%) in round 1 and 136/158 (86%) in round 2. The majority of participants were nurses (35%) or doctors (39%) from Europe (55%) or North America (35%). All 87 items in round 1 reached consensus with an additional 15 items identified for round 2, which also reached consensus. The strength of agreement was mostly high for statements. The areas of competence rated most important were agreed to be: ‘Identify the impact of disease on young people's life’ (skill), ‘Know about side effects of treatment and how this might be different to those experienced by children or older adults’ (knowledge), ‘Honesty’ (attitude) and ‘Listen to young people's concerns’ (aspect of communication). Conclusions Given the high degree of consensus, this list of competencies should influence education curriculum, professional development and inform workforce planning. Variation in strength of agreement for some competencies between professional groups should be explored

    The evidence base to support the prevention of haemophilic arthropathy remains incomplete. In particular there is a lack of evidence regarding the potential influence of non-haematological factors. Additionally the ankle joint, the most affected joint in the primary prophylaxis era, has biochemical and structural features that should offer some protection from degeneration. Therefore, this study aimed to ascertain expert opinions on the potential contributory factors in order to inform a research agenda. The Delphi method, a group forum technique to achieve consensus of expert opinion was selected. It allows anonymous participation of a geographically disparate panel. A modified three-round design was used with a multi-professional international panel from 11 countries, 280 suggestions with the potential to influence arthropathy development were submitted in Round 1. These were analysed for theme, giving 47 factors in four categories: musculoskeletal intrinsic, extrinsic affecting physical health, compliance, education and non-haematological management, and haemophilia related. Subsequently, consensus was ascertained on their importance for study. At survey completion, 31 panellists (86%) completed. 41 factors reached the pre-selected level for consensus and 6 were rejected. The breadth of the factors put forward suggests that the panel believe pathogenesis of HA is multifactorial. Panel composition indicates results with high face and content validity capable of guiding future research. Developing an understanding of the relative influence of factors in each patient has the potential of not only individualizing replacement therapy with regard to frequency and trough levels but also individualizing other interventions that promote musculoskeletal health.

    Background Ethnic minority groups are under-represented in mental health care services because of barriers such as poor mental health literacy. In 2007, the Mental Health First Aid (MHFA) program implemented a cultural adaptation of its first aid course to improve the capacity of Indigenous Australians to recognise and respond to mental health issues within their own communities. It became apparent that the content of this training would be improved by the development of best practice guidelines. This research aimed to develop culturally appropriate guidelines for providing first aid to an Australian Aboriginal or Torres Strait Islander person who is experiencing a mental health crisis or developing a mental illness. Methods A panel of Australian Aboriginal people who are experts in Aboriginal mental health, participated in six independent Delphi studies investigating depression, psychosis, suicidal thoughts and behaviours, deliberate self-injury, trauma and loss, and cultural considerations. The panel varied in size across the studies, from 20-24 participants. Panellists were presented with statements about possible first aid actions via online questionnaires and were encouraged to suggest additional actions not covered by the survey content. Statements were accepted for inclusion in a guideline if they were endorsed by ≥ 90% of panellists as essential or important. Each study developed one guideline from the outcomes of three Delphi questionnaire rounds. At the end of the six Delphi studies, participants were asked to give feedback on the value of the project and their participation experience. Results From a total of 1,016 statements shown to the panel of experts, 536 statements were endorsed (94 for depression, 151 for psychosis, 52 for suicidal thoughts and behaviours, 53 for deliberate self-injury, 155 for trauma and loss, and 31 for cultural considerations). The methodology and the guidelines themselves were found to be useful and appropriate by the

    The current debate in the U.S. Human Spaceflight Program focuses on the development of the next generation of man-rated heavy lift launch vehicles. While launch vehicle systems are of critical importance for future exploration, a comprehensive analysis of the entire exploration infrastructure is required to avoid costly pitfalls at early stages of the design process. This paper addresses this need by presenting a Delphi-Based Systems Architecting Framework for integrated architectural analysis of future in-orbit infrastructure for human space exploration beyond Low Earth Orbit. The paper is structured in two parts. The first part consists of an expert elicitation study to identify objectives for the in-space transportation infrastructure. The study was conducted between November 2011 and January 2012 with 15 senior experts involved in human spaceflight in the United States and Europe. The elicitation study included the formation of three expert panels representing exploration, science, and policy stakeholders engaged in a 3-round Delphi study. The rationale behind the Delphi approach, as imported from social science research, is discussed. Finally, a novel version of the Delphi method is presented and applied to technical decision-making and systems architecting in the context of human space exploration. The second part of the paper describes a tradespace exploration study of in-orbit infrastructure coupled with a requirements definition exercise informed by expert elicitation. The uncertainties associated with technical requirements and stakeholder goals are explicitly considered in the analysis. The outcome of the expert elicitation process portrays an integrated view of perceived stakeholder needs within the human spaceflight community. Needs are subsequently converted into requirements and coupled to the system architectures of interest to analyze the correlation between exploration, science, and policy goals. Pareto analysis is used to identify architectures

  7. Research priorities for child and adolescent physical activity and sedentary behaviours: an international perspective using a twin-panel Delphi procedure

    2013-01-01

    Background The quantity and quality of studies in child and adolescent physical activity and sedentary behaviour have rapidly increased, but research directions are often pursued in a reactive and uncoordinated manner. Aim To arrive at an international consensus on research priorities in the area of child and adolescent physical activity and sedentary behaviour. Methods Two independent panels, each consisting of 12 experts, undertook three rounds of a Delphi methodology. The Delphi methodology required experts to anonymously answer questions put forward by the researchers with feedback provided between each round. Results The primary outcome of the study was a ranked set of 29 research priorities that aimed to be applicable for the next 10 years. The top three ranked priorities were: developing effective and sustainable interventions to increase children’s physical activity long-term; policy and/or environmental change and their influence on children’s physical activity and sedentary behaviour; and prospective, longitudinal studies of the independent effects of physical activity and sedentary behaviour on health. Conclusions These research priorities can help to guide decisions on future research directions. PMID:24228891

    Background Motor learning is central to domains such as sports and rehabilitation; however, often terminologies are insufficiently uniform to allow effective sharing of experience or translation of knowledge. A study using a Delphi technique was conducted to ascertain level of agreement between experts from different motor learning domains (i.e., therapists, coaches, researchers) with respect to definitions and descriptions of a fundamental conceptual distinction within motor learning, namely implicit and explicit motor learning. Methods A Delphi technique was embedded in multiple rounds of a survey designed to collect and aggregate informed opinions of 49 international respondents with expertise related to motor learning. The survey was administered via an online survey program and accompanied by feedback after each round. Consensus was considered to be reached if ≥70% of the experts agreed on a topic. Results Consensus was reached with respect to definitions of implicit and explicit motor learning, and seven common primary intervention strategies were identified in the context of implicit and explicit motor learning. Consensus was not reached with respect to whether the strategies promote implicit or explicit forms of learning. Discussion The definitions and descriptions agreed upon may aid translation and transfer of knowledge between domains in the field of motor learning. Empirical and clinical research is required to confirm the accuracy of the definitions and to explore the feasibility of the strategies that were identified in research, everyday practice and education.

    This article outlines how learning objectives based upon science, technology and society (STS) elements for Palestinian ninth grade science textbooks were identified, which was part of a bigger study to establish an STS foundation in the ninth grade science curriculum in Palestine. First, an initial list of STS elements was determined. Second, using this list, ninth grade science textbooks and curriculum document contents were analyzed. Third, based on this content analysis, a possible list of 71 learning objectives for the integration of STS elements was prepared. This list of learning objectives was refined by using a two-round Delphi technique. The Delphi study was used to rate and to determine the consensus regarding which items (i.e. learning objectives for STS in the ninth grade science textbooks in Palestine) are to be accepted for inclusion. The results revealed that of the initial 71 objectives in round one, 59 objectives within round two had a mean score of 5.683 or higher, which indicated that the learning objectives could be included in the development of STS modules for ninth grade science in Palestine.

    Objective We have undertaken a multi-phase, multi-method program of research to develop, implement, and evaluate a comprehensive hospital-based nurse examiner elder abuse intervention that addresses the complex functional, social, forensic, and medical needs of older women and men. In this study, we determined the importance of possible participating professionals and respective roles and responsibilities within the intervention. Methods Using a modified Delphi methodology, recommended professionals and their associated roles and responsibilities were generated from a systematic scoping review of relevant scholarly and grey literatures. These items were reviewed, new items added for review, and rated/re-rated for their importance to the intervention on a 5-point Likert scale by an expert panel during a one day in-person meeting. Items that did not achieve consensus were subsequently re-rated in an online survey. Analysis Those items that achieved a mean Likert rating of 4+ (rated important to very important), and an interquartile range<1 in the first or second round, and/or for which 80% of ratings were 4+ in the second round were retained for the model elder abuse intervention. Results Twenty-two of 31 recommended professionals and 192 of 229 recommended roles and responsibilities rated were retained for our model elder abuse intervention. Retained professionals were: public guardian and trustee (mean rating = 4.88), geriatrician (4.87), police officer (4.87), GEM (geriatric emergency management) nurse (4.80), GEM social worker (4.78), community health worker (4.76), social worker/counsellor (4.74), family physician in community (4.71), paramedic (4.65), financial worker (4.59), lawyer (4.59), pharmacist (4.59), emergency physician (4.57), geriatric psychiatrist (4.33), occupational therapist (4.29), family physician in hospital (4.28), Crown prosecutor (4.24), neuropsychologist (4.24), bioethicist (4.18), caregiver advocate (4.18), victim support worker (4

  11. Development of the Migrant Friendly Maternity Care Questionnaire (MFMCQ) for migrants to Western societies: an international Delphi consensus process

    PubMed Central

    2014-01-01

    Background Through the World Health Assembly Resolution, ‘Health of Migrants’, the international community has identified migrant health as a priority. Recommendations for general hospital care for international migrants in receiving-countries have been put forward by the Migrant Friendly Hospital Initiative; adaptations of these recommendations specific to maternity care have yet to be elucidated and validated. We aimed to develop a questionnaire measuring migrant-friendly maternity care (MFMC) which could be used in a range of maternity care settings and countries. Methods This study was conducted in four stages. First, questions related to migrant friendly maternity care were identified from existing questionnaires including the Migrant Friendliness Quality Questionnaire, developed in Europe to capture recommended general hospital care for migrants, and the Mothers In a New Country (MINC) Questionnaire, developed in Australia and revised for use in Canada to capture the maternity care experiences of migrant women, and combined to create an initial MFMC questionnaire. Second, a Delphi consensus process in three rounds with a panel of 89 experts in perinatal health and migration from 17 countries was undertaken to identify priority themes and questions as well as to clarify wording and format. Third, the draft questionnaire was translated from English to French and Spanish and back-translated and subsequently culturally validated (assessed for cultural appropriateness) by migrant women. Fourth, the questionnaire was piloted with migrant women who had recently given birth in Montreal, Canada. Results A 112-item questionnaire on maternity care from pregnancy, through labour and birth, to postpartum care, and including items on maternal socio-demographic, migration and obstetrical characteristics, and perceptions of care, has been created - the Migrant Friendly Maternity Care Questionnaire (MFMCQ) – in three languages (English, French and Spanish).

  12. Beyond knowledge and skills: the use of a Delphi study to develop a technology-mediated teaching strategy

    PubMed Central

    2013-01-01

    Background While there is evidence to suggest that teaching practices in clinical education should include activities that more accurately reflect the real world, many educators base their teaching on transmission models that encourage the rote learning of knowledge and technical skills. Technology-mediated instruction may facilitate the development of professional attributes that go beyond “having” knowledge and skills, but there is limited evidence for how to integrate technology into these innovative teaching approaches. Methods This study used a modified Delphi method to help identify the professional attributes of capable practitioners, the approaches to teaching that may facilitate the development of these attributes, and finally, how technology could be integrated with those teaching strategies in order to develop capable practitioners. Open-ended questions were used to gather data from three different expert panels, and results were thematically analysed. Results Clinical educators should not view knowledge, skills and attitudes as a set of products of learning, but rather as a set of attributes that are developed during a learning process. Participants highlighted the importance of continuing personal and professional development that emphasised the role of values and emotional response to the clinical context. To develop these attributes, clinical educators should use teaching activities that are learner-centred, interactive, integrated, reflective and that promote engagement. When technology-mediated teaching activities are considered, they should promote the discussion of clinical encounters, facilitate the sharing of resources and experiences, encourage reflection on the learning process and be used to access content outside the classroom. In addition, educational outcomes must drive the integration of technology into teaching practice, rather than the features of the technology. Conclusions There is a need for a cultural change in clinical

    2012-01-01

    Background Within the 52 health districts in South Africa, the family physician is seen as the clinical leader within a multi-professional district health team. Family physicians must be competent to meet 90% of the health needs of the communities in their districts. The eight university departments of Family Medicine have identified five unit standards, broken down into 85 training outcomes, for postgraduate training. The family medicine registrar must prove at the end of training that all the required training outcomes have been attained. District health managers must be assured that the family physician is competent to deliver the expected service. The Colleges of Medicine of South Africa (CMSA) require a portfolio to be submitted as part of the uniform assessment of all registrars applying to write the national fellowship examinations. This study aimed to achieve a consensus on the contents and principles of the first national portfolio for use in family medicine training in South Africa. Methods A workshop held at the WONCA Africa Regional Conference in 2009 explored the purpose and broad contents of the portfolio. The 85 training outcomes, ideas from the WONCA workshop, the literature, and existing portfolios in the various universities were used to develop a questionnaire that was tested for content validity by a panel of 31 experts in family medicine in South Africa, via the Delphi technique in four rounds. Eighty five content items (national learning outcomes) and 27 principles were tested. Consensus was defined as 70% agreement. For those items that the panel thought should be included, they were also asked how to provide evidence for the specific item in the portfolio, and how to assess that evidence. Results Consensus was reached on 61 of the 85 national learning outcomes. The panel recommended that 50 be assessed by the portfolio and 11 should not be. No consensus could be reached on the remaining 24 outcomes and these were also omitted from the

    This Cooperative Research and Development Agreement (CRADA) report deals with the development of nickel aluminide alloy for improved longer life heat-resistant fixture assemblies for batch and continuous pusher carburizing furnaces. The nickel aluminide development was compared in both coupon and component testing with the currently used Fe-Ni-Cr heat-resisting alloy known as HU. The specific goals of the CRADA were: (1) casting process development, (2) characterization and possible modification of the alloy composition to optimize its manufacturing ability and performance under typical furnace operating conditions, and (3) testing and evaluation of specimens and prototype fixtures. In support of the CRADA objectives, coupons of nickel aluminide and the HU alloy were installed in both batch and pusher furnaces. The coupons were taken from two silicon levels and contained welds made with two different filler compositions (IC-221LA and IC-221W). Both nickel-aluminide and HU coupons were removed from the batch and pusher carburizing furnace at time intervals ranging from one month to one year. The exposed coupons were cut and mounted for metallographic, hardness, and microprobe analysis. The results of the microstructural analysis have been transmitted to General Motors Corporation, Saginaw Division (Delphi Saginaw) through reports that were presented at periodic CRADA review meetings. Based on coupon testing and verification of the coupon results with the testing of trays, Delphi Saginaw moved forward with the use of six additional trays in a batch furnace and two assemblies in a pusher furnace. Fifty percent of the trays and fixtures are in the as-cast condition and the remaining trays and fixtures are in the preoxidized condition. The successful operating experience of two assemblies in the pusher furnace for nearly a year formed the basis for a production run of 63 more assemblies. The production run required melting of 94 heats weighing 500 lb. each. Twenty

    ABSTRACT Background: Quality indicators are measured aspects of healthcare, reflecting the performance of a healthcare provider or healthcare system. They have a crucial role in programmes to assess and improve healthcare. Many performance measures for primary care have been developed. Only the Catalan model for patient safety in primary care identifies key domains of patient safety in primary care. Objective: To present an international framework for patient safety indicators in primary care. Methods: Literature review and online Delphi-survey, starting from the Catalan model. Results: A set of 30 topics is presented, identified by an international panel and organized according to the Catalan model for patient safety in primary care. Most topic areas referred to specific clinical processes; additional topics were leadership, people management, partnership and resources. Conclusion: The framework can be used to organize indicator development and guide further work in the field. PMID:26339833

    2013-01-01

    Background Globally, moderate acute malnutrition (MAM) and severe acute malnutrition (SAM) affect approximately 52 million children under five. This systematic review evaluates the effectiveness of interventions for SAM including the World Health Organization (WHO) protocol for inpatient management and community-based management with ready-to-use-therapeutic food (RUTF), as well as interventions for MAM in children under five years in low- and middle-income countries. Methods We systematically searched the literature and included 14 studies in the meta-analysis. Study quality was assessed using CHERG adaptation of GRADE criteria. A Delphi process was undertaken to complement the systematic review in estimating case fatality and recovery rates that were necessary for modelling in the Lives Saved Tool (LiST). Results Case fatality rates for inpatient treatment of SAM using the WHO protocol ranged from 3.4% to 35%. For community-based treatment of SAM, children given RUTF were 51% more likely to achieve nutritional recovery than the standard care group. For the treatment of MAM, children in the RUSF group were significantly more likely to recover and less likely to be non-responders than in the CSB group. In both meta-analyses, weight gain in the intervention group was higher, and although statistically significant, these differences were small. Overall limitations in our analysis include considerable heterogeneity in many outcomes and an inability to evaluate intervention effects separate from commodity effect. The Delphi process indicated that adherence to standardized protocols for the treatment of SAM and MAM should have a marked positive impact on mortality and recovery rates; yet, true consensus was not achieved. Conclusions Gaps in our ability to estimate effectiveness of overall treatment approaches for SAM and MAM persist. In addition to further impact studies conducted in a wider range of settings, more high quality program evaluations need to be conducted

    Background The British Medical Journal's (BMJ's) patient revolution strives for collaboration with patients in healthcare and health research. This paper studies collaboration with people with intellectual disabilities (ID) in health research, also known as inclusive health research. Currently, transparency and agreement among academics is lacking regarding its main aspects, preventing upscaling of the patient revolution. Objective This study aims to gain agreement among academics on 3 aspects of inclusive health research for people with ID: (1) designs and methods, (2) most important characteristics and (3) outcomes. Design A Delphi study was conducted with academics with experience in inclusive (health) research and on people with ID. The study consisted of 2 sequential questionnaire rounds (n=24; n=17), followed by in-depth interviews (n=10). Results Academics agreed on (1) a collaborative approach to be most suitable to inclusive health research, (2) characteristics regarding the accessibility and facilitation of inclusive health research, and (3) several outcomes of inclusive health research for people with ID and healthcare. Other characteristics agreed on included: atmosphere, relationship, engagement, partnership and power. It was stressed that these characteristics ensure meaningful inclusion. Interviewed academics voiced the need for a tool supporting the facilitation and evaluation of inclusive health research. There was ambiguity as to what this tool should comprise and the extent to which it was possible to capture the complex process of inclusive health research. Discussion and conclusions This study underlines the need for transparency, facilitation and evaluation of inclusive health research. The need for in-depth interviews after 2 Delphi rounds underlines its complexity and context dependence. To increase process transparency, future research should focus on gaining insight into inclusive health research in its context. A tool could be developed

  18. Essential key indicators for disaster medical response suggested to be included in a national uniform protocol for documentation of major incidents: a Delphi study

    PubMed Central

    2013-01-01

    Background Registration of data from a major incident or disaster serves several purposes such as to record data for evaluation of response as well as for research. Data needed can often be retrieved after an incident while other must be recorded during the incident. There is a need for a consensus on what is essential to record from a disaster response. The aim of this study was to identify key indicators essential for initial disaster medical response registration. By this is meant nationally accepted processes involved, from the time of the emergency call to the emergency medical communication centre until medical care is provided at the emergency department. Methods A three round Delphi study was conducted. Thirty experts with a broad knowledge in disaster and emergency response and medical management were invited. In this study we estimated 30 experts to be approximately one third of the number in Sweden eligible for recruitment. Process, structure and outcome indicators for the initial disaster medical response were identified. These were based on previous research and expressed as statements and were grouped into eight categories, and presented to the panel of experts. The experts were instructed to score each statement, using a five point Likert scale, and were also invited to include additional statements. Statements reaching a predefined consensus level of 80% were considered as essential to register. Results In total 97 statements were generated, 77 statements reached consensus. The 77 statements covered parts of all relevant aspects involved in the initial disaster medical response. The 20 indicators that did not reach consensus mostly concerned patient related times in hospital, types of support systems and security for health care staff. Conclusions The Delphi technique can be used for reaching consensus of data, comprising process, structure and outcome indicators, identified as essential for recording from major incidents and disasters.

    Background Continuing medical education (CME) is compulsory for physicians in Iran. Recent studies in Iran show that modifications of CME elements are necessary to improve the effectiveness of the educational programmes. Other studies point to an inappropriate, even irrational drug prescribing. Based on a needs assessment study regarding CME for general physicians in the East Azerbaijan province in Iran, rational prescribing practice was recognized as a high priority issue. Considering different educational methods, outcome-based education has been proposed as a suitable approach for CME. The purpose of the study was to obtain experts' consensus about appropriate educational outcomes of rational prescribing for general physicians in CME and developing curricular contents for this education. Methods The study consisted of two phases: The first phase was conducted using a two-round Delphi consensus process to identify the outcome-based educational indicators regarding rational prescribing for general physicians in primary care (GPs). In the second phase the agreed indicators were submitted to panels of experts for assessment and determination of content for a CME program in the field. Results Twenty one learning outcomes were identified through a modified Delphi process. The indicators were used by the panels of experts and six educational topics were determined for the CME programme and the curricular content of each was defined. The topics were 1) Principles of prescription writing, 2) Adverse drug reactions, 3) Drug interactions, 4) Injections, 5) Antibiotic therapy, and 6) Anti-inflammatory agents therapy. One of the topics was not directly related to any outcome, raising a question about the need for a discussion on constructive alignment. Conclusions Consensus on learning outcomes was achieved and an educational guideline was designed. Before suggesting widespread use in the country the educational package should be tested in the CME context. PMID:18510774

  20. Neonatal resuscitation and immediate newborn assessment and stimulation for the prevention of neonatal deaths: a systematic review, meta-analysis and Delphi estimation of mortality effect

    PubMed Central

    2011-01-01

    Background Of 136 million babies born annually, around 10 million require assistance to breathe. Each year 814,000 neonatal deaths result from intrapartum-related events in term babies (previously “birth asphyxia”) and 1.03 million from complications of prematurity. No systematic assessment of mortality reduction from tactile stimulation or resuscitation has been published. Objective To estimate the mortality effect of immediate newborn assessment and stimulation, and basic resuscitation on neonatal deaths due to term intrapartum-related events or preterm birth, for facility and home births. Methods We conducted systematic reviews for studies reporting relevant mortality or morbidity outcomes. Evidence was assessed using GRADE criteria adapted to provide a systematic approach to mortality effect estimates for the Lives Saved Tool (LiST). Meta-analysis was performed if appropriate. For interventions with low quality evidence but strong recommendation for implementation, a Delphi panel was convened to estimate effect size. Results We identified 24 studies of neonatal resuscitation reporting mortality outcomes (20 observational, 2 quasi-experimental, 2 cluster randomized controlled trials), but none of immediate newborn assessment and stimulation alone. A meta-analysis of three facility-based studies examined the effect of resuscitation training on intrapartum-related neonatal deaths (RR= 0.70, 95%CI 0.59-0.84); this estimate was used for the effect of facility-based basic neonatal resuscitation (additional to stimulation). The evidence for preterm mortality effect was low quality and thus expert opinion was sought. In community-based studies, resuscitation training was part of packages with multiple concurrent interventions, and/or studies did not distinguish term intrapartum-related from preterm deaths, hence no meta-analysis was conducted. Our Delphi panel of 18 experts estimated that immediate newborn assessment and stimulation would reduce both intrapartum

    2016-01-01

    Background Some midwives are known to experience both professional and organizational sources of psychological distress, which can manifest as a result of the emotionally demanding midwifery work, and the traumatic work environments they endure. An online intervention may be one option midwives may engage with in pursuit of effective support. However, the priorities for the development of an online intervention to effectively support midwives in work-related psychological distress have yet to be explored. Objective The aim of this study was to explore priorities in the development of an online intervention to support midwives in work-related psychological distress. Methods A two-round online Delphi study was conducted. This study invited both qualitative and quantitative data from experts recruited via a scoping literature search and social media channels. Results In total, 185 experts were invited to participate in this Delphi study. Of all participants invited to contribute, 35.7% (66/185) completed Round 1 and of those who participated in this first round, 67% (44/66) continued to complete Round 2. Out of 39 questions posed over two rounds, 18 statements (46%) achieved consensus, 21 (54%) did not. Participants were given the opportunity to write any additional comments as free text. In total, 1604 free text responses were collected and categorized into 2446 separate statements of opinion, creating a total of 442 themes. Overall, participants agreed that in order to effectively support midwives in work-related psychological distress, online interventions should make confidentiality and anonymity a high priority, along with 24-hour mobile access, effective moderation, an online discussion forum, and additional legal, educational, and therapeutic components. It was also agreed that midwives should be offered a simple user assessment to identify those people deemed to be at risk of either causing harm to others or experiencing harm themselves, and direct them to

  2. Development of mental health first aid guidelines on how a member of the public can support a person affected by a traumatic event: a Delphi study

    PubMed Central

    2010-01-01

    Background People who experience traumatic events have an increased risk of developing a range of mental disorders. Appropriate early support from a member of the public, whether a friend, family member, co-worker or volunteer, may help to prevent the onset of a mental disorder or may minimise its severity. However, few people have the knowledge and skills required to assist. Simple guidelines may help members of the public to offer appropriate support when it is needed. Methods Guidelines were developed using the Delphi method to reach consensus in a panel of experts. Experts recruited to the panels included 37 professionals writing, planning or working clinically in the trauma area, and 17 consumer or carer advocates who had been affected by traumatic events. As input for the panels to consider, statements about how to assist someone who has experienced a traumatic event were sourced through a systematic search of both professional and lay literature. These statements were used to develop separate questionnaires about possible ways to assist adults and to assist children, and panel members answered either one questionnaire or both, depending on experience and expertise. The guidelines were written using the items most consistently endorsed by the panels across the three Delphi rounds. Results There were 180 items relating to helping adults, of which 65 were accepted, and 155 items relating to helping children, of which 71 were accepted. These statements were used to develop the two sets of guidelines appended to this paper. Conclusions There are a number of actions which may be useful for members of the public when they encounter someone who has experienced a traumatic event, and it is possible that these actions may help prevent the development of some mental health problems in the future. Positive social support, a strong theme in these guidelines, has some evidence for effectiveness in developing mental health problems in people who have experienced traumatic

    PubMed Central

    2011-01-01

    Background Annually over 520,000 newborns die from neonatal sepsis, and 60,000 more from tetanus. Estimates of the effect of clean birth and postnatal care practices are required for evidence-based program planning. Objective To review the evidence for clean birth and postnatal care practices and estimate the effect on neonatal mortality from sepsis and tetanus for the Lives Saved Tool (LiST). Methods We conducted a systematic review of multiple databases. Data were abstracted into standard tables and assessed by GRADE criteria. Where appropriate, meta-analyses were undertaken. For interventions with low quality evidence but a strong GRADE recommendation, a Delphi process was conducted. Results Low quality evidence supports a reduction in all-cause neonatal mortality (19% (95% c.i. 1–34%)), cord infection (30% (95% c.i. 20–39%)) and neonatal tetanus (49% (95% c.i. 35–62%)) with birth attendant handwashing. Very low quality evidence supports a reduction in neonatal tetanus mortality with a clean birth surface (93% (95% c.i. 77-100%)) and no relationship between a clean perineum and tetanus. Low quality evidence supports a reduction of neonatal tetanus with facility birth (68% (95% c.i. 47-88%). No relationship was found between birth place and cord infections or sepsis mortality. For postnatal clean practices, all-cause mortality is reduced with chlorhexidine cord applications in the first 24 hours of life (34% (95% c.i. 5–54%, moderate quality evidence) and antimicrobial cord applications (63% (95% c.i. 41–86%, low quality evidence). One study of postnatal maternal handwashing reported reductions in all-cause mortality (44% (95% c.i. 18–62%)) and cord infection ((24% (95% c.i. 5-40%)). Given the low quality of evidence, a Delphi expert opinion process was undertaken. Thirty experts reached consensus regarding reduction of neonatal sepsis deaths by clean birth practices at home (15% (IQR 10–20)) or in a facility (27% IQR 24–36)), and by clean

    Over the past twenty years, schools and districts have been faced with the challenge of integrating technology into their classroom instruction. The rapid rate of evolution that technology changes has placed new burdens on school and district leaders to plan meaningful professional development, create and develop effective policy, and focus on school and district culture. In the coming years, the changing nature of technology is not expected to slow down and most certainly will accelerate. The purpose of this Delphi study was to identify what K-12 superintendents should do to position their districts to be prepared for the changing nature of technology in the next 10 years. The expert panel for this study was comprised of K-12 superintendents from eight Northern California counties. This Delphi study consisted of three rounds. In Round 1, the expert panel identified 74 strategies that superintendents should do to position their districts to be prepared for the changing nature of technology in the next 10 years. Those items were thematically categorized and where then narrowed down into a list of 30 strategies in preparation for Round 2. During Round 2, the expert panel rated the 30 strategies on the level of influence it would have on preparing districts for the changing nature of technology in the next 10 years using a 6-point Likert scale. In Round 3, each panel member was given the mean rating for each item as well as their own ratings for each item. Each panel member was then given the opportunity to change their ratings to the Round 2 survey. The expert panel identified four strategies which had the highest combined mean and median scores as well as an interquartile range of less than two. Each of the strategies from Round 2 and 3 had a mean score of four or higher. However, consensus was reached on four strategies which were rated with the highest combined mean and median scores. The four highest rated strategies were represented by three categories: culture

    Background Tracing persons who have been in contact with an infectious patient may be very effective in preventing the spread of communicable diseases. However, criteria to decide when to conduct contact tracing are not well established. We have investigated the available evidence for contact tracing with a focus on public ground transport aiming to give guidance in what situations contact tracing should be considered. Methods Relevant infectious diseases suitable for contact tracing in ground transport and a set of disease-specific epidemiological criteria were defined through literature search and structured multistep expert consultations. We developed continuous scales for each criterion to be rated for its relevance to contact tracing in ground transport. We used the Delphi method with an international expert panel to position the values of criteria on the respective scales. Results The study led to the development of the ‘Contact Tracing-Risk Assessment Profile’ (CT-RAP), a decision-making instrument, taking into account pathogen-specific as well as situation-specific criteria. This report describes the methodology of this instrument and presents two examples of ready-to-use CT-RAP for tuberculosis and for meningococcal disease in public ground transport. Discussion The systematic and transparent use of the CT-RAP for tuberculosis and meningococcal disease is likely to facilitate reasonable, efficient and user-friendly decisions with respect to contact tracing. New CT-RAPs for additional pathogens and different settings such as schools and kindergartens are being planned. PMID:24157815

    There has been a surge of interest regarding the application of resilience theory in childcare practice and how resilience can be promoted among vulnerable children, in particular, looked after children. However, little is known about how people working with looked after children understand the concept of resilience. This study aimed to explore how social workers, teachers and foster carers, working with looked after children, understand resilience and whether there is consensus as to what constitutes resilience. The study also sought to explore whether there are differences in how resilience is constructed across these groups. In total, 106 participants took part in a Delphi survey (34 teachers, 36 foster carers, 36 social workers). There was moderate consensus that resilience related to survival, coping and a sense of self-worth. Resilience was not considered a panacea but a concept that also had limitations. Participants understood resilience in ways that were both similar and different to existing conceptualisations within the literature. However, there were many aspects of resilience for which there was no consensus or significant difference of opinion between the participant groups. The need for further training and research is discussed, in order to support attempts to promote resilience among looked after children. PMID:25814650

    3-MCC deficiency is among the most common inborn errors of metabolism identified on expanded newborn screening (1:36,000 births). However, evidence-based guidelines for diagnosis and management of this disorder are lacking. Using the traditional Delphi method, a panel of 15 experts in inborn errors of metabolism was convened to develop consensus-based clinical practice guidelines for the diagnosis and management of 3-MCC screen-positive infants and their mothers. The Oxford Centre for Evidence-based Medicine system was used to grade the literature review and create recommendations graded from A (evidence level of randomized clinical trials) to D (expert opinion). Panelists reviewed the initial evaluation of the screen-positive infant-mother dyad, diagnostic guidelines, and management of diagnosed patients. Grade D consensus recommendations were made in each of these three areas. The panel did not reach consensus on all issues. This consensus protocol is intended to assist clinicians in the diagnosis and management of screen-positive newborns for 3-MCC deficiency and to encourage the development of evidence-based guidelines.

    In Mexico, regular participation in mammography screening is low, despite higher survival rates. The objective of our research is to highlight healthcare procedures to be optimized and target areas to encourage investment and to raise awareness about the benefits of early diagnosis. Those socio-ecological factors (community, interpersonal and individual) were collected through a review of literature and based on the spatial interaction model of mammography use developed by Mobley et al. The opinion of diverse groups of experts on the importance of those factors was collected by survey. The Fuzzy Delphi Method helped to solve the inherent uncertainty of the survey process. Our findings suggest that population health behaviors, proximity-density to facilities/ physicians and predisposing factors are needed to increase the screening rate. Variations in expert group size could affect the accuracy of the conclusions. However, the application of the enhanced aggregation method provided a group consensus that is less susceptible to misinterpretation and that weighs the opinion of each expert according to their clinical experience in mammography research.

    Despite the evidence base, alcohol screening and brief intervention (ASBI) have rarely been integrated into routine clinical practice. The aim of this study is to identify strategies that could tackle barriers to ASBI implementation in general practice by involving primary healthcare professionals and addiction prevention experts. A three-round online Delphi study was carried out in the Netherlands. The first-round questionnaire consisted of open-ended questions to generate ideas about strategies to overcome barriers. In the second round, participants were asked to indicate how applicable they found each strategy. Items without consensus were systematically fed back with group median ratings and interquartile range (IQR) scores in the third-round questionnaire. In total, 39 out of 69 (57 %) invited participants enrolled in the first round, 214 participants completed the second round, and 144 of these (67 %) completed the third-round questionnaire. Results show that participants reached consensus on 59 of 81 strategies, such as the following: (1) use of E-learning technology, (2) symptom-specific screening by general practitioners (GPs) and/or universal screening by practice nurses, (3) reimbursement incentives, (4) supportive materials, (5) clear guidelines, (6) service provision of addiction care centers, and (7) more publicity in the media. This exploratory study identified a broad set of strategies that could potentially be used for overcoming barriers to ASBI implementation in general practice and paves the way for future research to experimentally test the identified implementation strategies using multifaceted approaches.

    Pseudomyxoma peritonei (PMP) is a complex disease with unique biological behavior that usually arises from appendiceal mucinous neoplasia. The classification of PMP and its primary appendiceal neoplasia is contentious, and an international modified Delphi consensus process was instigated to address terminology and definitions. A classification of mucinous appendiceal neoplasia was developed, and it was agreed that "mucinous adenocarcinoma" should be reserved for lesions with infiltrative invasion. The term "low-grade appendiceal mucinous neoplasm" was supported and it was agreed that "cystadenoma" should no longer be recommended. A new term of "high-grade appendiceal mucinous neoplasm" was proposed for lesions without infiltrative invasion but with high-grade cytologic atypia. Serrated polyp with or without dysplasia was preferred for tumors with serrated features confined to the mucosa with an intact muscularis mucosae. Consensus was achieved on the pathologic classification of PMP, defined as the intraperitoneal accumulation of mucus due to mucinous neoplasia characterized by the redistribution phenomenon. Three categories of PMP were agreed-low grade, high grade, and high grade with signet ring cells. Acellular mucin should be classified separately. It was agreed that low-grade and high-grade mucinous carcinoma peritonei should be considered synonymous with disseminated peritoneal adenomucinosis and peritoneal mucinous carcinomatosis, respectively. A checklist for the pathologic reporting of PMP and appendiceal mucinous neoplasms was also developed. By adopting the classifications and definitions that were agreed, different centers will be able to use uniform terminology that will allow meaningful comparison of their results. PMID:26492181

    With 3.2 million hadronic Z^0 decays recorded by DELPHI between 1991 and 1994 (1995), the mass difference between the two physical B^0d states has been measured using the high transverse momentum (p_t) lepton charge or the mean charge of the event hemisphere to sign the flavour of the b-quark at the production time and using the charge of a high pt lepton or of a D to sign the presence of a B^0d or \\overlineB^0d at the decay time. A lower limit on the mass difference between the B^0s states has been found with the same method used for B^0d to sign the presence of a b or \\overlineb at the production and the charge of a high pt lepton or of a Ds from B^0s semileptonic decay to sign the B^0s or \\overlineB^0s at the decay.

    Objective To identify the main areas of uncertainty and subsequent research priorities to inform the ongoing debate around assisted dying. Design Two-round electronic modified Delphi consultation with experts and interested bodies. Setting and participants 110 groups and individuals interested in the subject of end-of-life care and/or assisted dying were approached to participate. Respondents included health and social care professionals, researchers, campaigners, patients and carers predominantly based in the UK. In the first round, the respondents were asked to propose high-priority research questions related to the topic of assisted dying. The collected research questions were then deduplicated and presented to all respondents in a second round in which they could rate each question in terms of importance. Results 24% and 26% of participants responded to the first and second rounds, respectively. Respondents suggested 85 unique research questions in the first round. These were grouped by theme and rated in terms of importance in the second round. Emergent themes were as follows: palliative care/symptom control; patient characteristics, experiences and decisions; families and carers; society and the general public; arguments for and against assisted dying; international experiences/analysis of existing national data; suicide; mental health, psychological and psychosocial considerations; comorbidities; the role of clinicians; environment and external influences; broader topics incorporating assisted dying; and moral, ethical and legal issues. 10 of the 85 proposed questions were rated as being important (≥7/10) by at least 50% of respondents. Conclusions Research questions with the highest levels of consensus were predominantly concerned with understanding how and why people make end-of-life decisions, and which factors influence those decisions. Dissemination of these findings alongside a focused examination of the existing literature may be the most effective

    Background: People with intellectual disabilities often present with unique challenges that make it more difficult to meet their palliative care needs. Aim: To define consensus norms for palliative care of people with intellectual disabilities in Europe. Design: Delphi study in four rounds: (1) a taskforce of 12 experts from seven European countries drafted the norms, based on available empirical knowledge and regional/national guidelines; (2) using an online survey, 34 experts from 18 European countries evaluated the draft norms, provided feedback and distributed the survey within their professional networks. Criteria for consensus were clearly defined; (3) modifications and recommendations were made by the taskforce; and (4) the European Association for Palliative Care reviewed and approved the final version. Setting and participants: Taskforce members: identified through international networking strategies. Expert panel: a purposive sample identified through taskforce members’ networks. Results: A total of 80 experts from 15 European countries evaluated 52 items within the following 13 norms: equity of access, communication, recognising the need for palliative care, assessment of total needs, symptom management, end-of-life decision making, involving those who matter, collaboration, support for family/carers, preparing for death, bereavement support, education/training and developing/managing services. None of the items scored less than 86% agreement, making a further round unnecessary. In light of respondents’ comments, several items were modified and one item was deleted. Conclusion: This White Paper presents the first guidance for clinical practice, policy and research related to palliative care for people with intellectual disabilities based on evidence and European consensus, setting a benchmark for changes in policy and practice.

    The patients' rights status is one of the essential elements in defining norms related to the concept of clinical governance system. In addition, the patients' rights status is an important index for quality of care offered in the health care system. However, the lack of a coherent instrument makes it difficult to evaluate patients' rights status in hospitals and clinics. The aim of this study was to develop an instrument for the evaluation of patients' rights prerequisites at educational hospitals in Iran. This study was conducted using the modified Delphi technique. In this study, 36 experts in the fields of law, medicine, and professional ethics were participated. The panel of experts participated in 3 rounds. First, experts were asked to judge some pre-identified items, and then, excluded items were judged again in the second round. At the end of the third round, all of the agreed items were included in the final list to form an evaluative scale on practice of patients' rights. Experts were asked to judge a total 171 items in 3 rounds. Around 31% (n = 53) of items obtained the panel's approval to be included in the final version of the scale. The experts' opinions were collected using face-to-face interviews and electronic email during a 6-month period of data collection from October 2013 to February 2014. This study developed a 53-item scale for evaluation of patients' rights prerequisites in educational hospitals in Iran. This scale was developed in 7 areas of commitments including university education, research, supervision, process management, physical structure, organizational policy, and human resources management. This study developed an evaluative scale to assess the practice of patients' rights in educational hospitals. The items in the final version of this scale were obtained from a consensus of experts and the instrument can be used to evaluate the context and prerequisites for practice of patients' rights in Iranian educational hospitals.

    For genetic research to contribute more fully to furthering our knowledge of neuropathic pain, we require an agreed, valid, and feasible approach to phenotyping, to allow collaboration and replication in samples of sufficient size. Results from genetic studies on neuropathic pain have been inconsistent and have met with replication difficulties, in part because of differences in phenotypes used for case ascertainment. Because there is no consensus on the nature of these phenotypes, nor on the methods of collecting them, this study aimed to provide guidelines on collecting and reporting phenotypes in cases and controls for genetic studies. Consensus was achieved through a staged approach: (1) systematic literature review to identify all neuropathic pain phenotypes used in previous genetic studies; (2) Delphi survey to identify the most useful neuropathic pain phenotypes and their validity and feasibility; and (3) meeting of experts to reach consensus on the optimal phenotype(s) to be collected from patients with neuropathic pain for genetic studies. A basic "entry level" set of phenotypes was identified for any genetic study of neuropathic pain. This set identifies cases of "possible" neuropathic pain, and controls, and includes: (1) a validated symptom-based questionnaire to determine whether any pain is likely to be neuropathic; (2) body chart or checklist to identify whether the area of pain distribution is neuroanatomically logical; and (3) details of pain history (intensity, duration, any formal diagnosis). This NeuroPPIC "entry level" set of phenotypes can be expanded by more extensive and specific measures, as determined by scientific requirements and resource availability. PMID:26469320

    Neuropathic pain (NP) in cancer patients lacks standards for diagnosis. This study is aimed at reaching consensus on the application of the International Association for the Study of Pain (IASP) special interest group for neuropathic pain (NeuPSIG) criteria to the diagnosis of NP in cancer patients and on the relevance of patient-reported outcome (PRO) descriptors for the screening of NP in this population. An international group of 42 experts was invited to participate in a consensus process through a modified 2-round Internet-based Delphi survey. Relevant topics investigated were: peculiarities of NP in patients with cancer, IASP NeuPSIG diagnostic criteria adaptation and assessment, and standardized PRO assessment for NP screening. Median consensus scores (MED) and interquartile ranges (IQR) were calculated to measure expert consensus after both rounds. Twenty-nine experts answered, and good agreement was found on the statement "the pathophysiology of NP due to cancer can be different from non-cancer NP" (MED=9, IQR=2). Satisfactory consensus was reached for the first 3 NeuPSIG criteria (pain distribution, history, and sensory findings; MEDs⩾8, IQRs⩽3), but not for the fourth one (diagnostic test/imaging; MED=6, IQR=3). Agreement was also reached on clinical examination by soft brush or pin stimulation (MEDs⩾7 and IQRs⩽3) and on the use of PRO descriptors for NP screening (MED=8, IQR=3). Based on the study results, a clinical algorithm for NP diagnostic criteria in cancer patients with pain was proposed. Clinical research on PRO in the screening phase and on the application of the algorithm will be needed to examine their effectiveness in classifying NP in cancer patients. PMID:25284070

    Background The child protection community is increasingly focused on developing tools to assess threats to child protection and the basic security needs and rights of children and families living in adverse circumstances. Although tremendous advances have been made to improve measurement of individual child health status or household functioning for use in low-resource settings, little attention has been paid to a more diverse array of settings in which many children in adversity spend time and how context contributes to threats to child protection. The SAFE model posits that insecurity in any of the following fundamental domains threatens security in the others: Safety/freedom from harm; Access to basic physiological needs and healthcare; Family and connection to others; Education and economic security. Site-level tools are needed in order to monitor the conditions that can dramatically undermine or support healthy child growth, development and emotional and behavioral health. From refugee camps and orphanages to schools and housing complexes, site-level threats exist that are not well captured by commonly used measures of child health and well-being or assessments of single households (e.g., SDQ, HOME). Methods The present study presents a methodology and the development of a scale for assessing site-level child protection threats in various settings of adversity. A modified Delphi panel process was enhanced with two stages of expert review in core content areas as well as review by experts in instrument development, and field pilot testing. Results Field testing in two diverse sites in India—a construction site and a railway station—revealed that the resulting SAFE instrument was sensitive to the differences between the sites from the standpoint of core child protection issues.

    Lateral distal femur (LDF) scans by dual-energy X-ray absorptiometry (DXA) are often feasible in children for whom other sites are not measurable. Pediatric reference data for LDF are not available for more recent DXA technology. The objective of this study was to assess older pediatric LDF reference data, construct new reference curves for LDF bone mineral density (BMD), and demonstrate the comparability of LDF BMD to other measures of BMD and strength assessed by DXA and by peripheral quantitative computed tomography (pQCT). LDF, spine and whole body scans of 821 healthy children, 5-18 yr of age, recruited at a single center were obtained using a Hologic Discovery/Delphi system (Hologic, Inc., Bedford, MA). Tibia trabecular and total BMD (3% site), cortical geometry (38% site) (cortical thickness, section modulus, and strain-strength index) were assessed by pQCT. Sex- and race-specific reference curves were generated using LMS Chartmaker (LMS Chartmaker Pro, version 2.3. Tim Cole and Huiqi Pan. Copyright 1997-2006, Medical Research Council, UK) and Z-scores calculated and compared by correlation analysis. Z-scores for LDF BMD based on published findings demonstrated overestimation or underestimation of the prevalence of low BMD-for-age depending on the region of interest considered. Revised LDF reference curves were generated. The new LDF Z-scores were strongly and significantly associated with weight, body mass index, spine and whole body BMD Z-scores, and all pQCT Z-scores. These findings demonstrate the comparability of LDF measurements to other clinical and research bone density assessment modes, and enable assessment of BMD in children with disabilities, who are particularly prone to low trauma fractures of long bones, and for whom traditional DXA measurement sites are not feasible.

    Introduction Orthopaedic oncology researchers face several obstacles in the design and execution of randomised controlled trials, including finite fiscal resources to support the rising costs of clinical research and insufficient patient volume at individual sites. As a result, high-quality research to guide clinical practice has lagged behind other surgical subspecialties. A focused approach is imperative to design a research programme that is economical, streamlined and addresses clinically relevant endpoints. The primary objective of this study will be to use a consensus-based approach to identify research priorities for international clinical trials in orthopaedic oncology. Methods and analysis We will conduct a 3-phase modified Delphi method consisting of 2 sequential rounds of anonymous web-based questionnaires (phases I and II), and an in-person consensus meeting (phase III). Participants will suggest research questions that they believe are of particular importance to the field (phase I), and individually rate each proposed question on 5 criteria (phase II). Research questions that meet predetermined consensus thresholds will be brought forward to the consensus meeting (phase III) for discussion by an expert panel. Following these discussions, the expert panel will be asked to assign scores for each research question, and research questions meeting predetermined criteria will be brought forward for final ranking. The expert panel will then be asked to rank the top 3 research questions, and these 3 research questions will be distributed to the initial group of participants for validation. Ethics and dissemination An ethics application is currently under review with the Hamilton Integrated Research Ethics Board in Hamilton, Ontario, Canada. The results of this initiative will be disseminated through peer-reviewed publications and conference presentations. PMID:27221129

    Objective The aim of this study was to learn about the progress of the prevention and control of major non-communicable diseases (NCDs) in China from 1990 to 2009 and to determine what prevention and control gaps remain based on the opinions of a group of panellists. Design Sixty-four panellists, who are members of the Subcommittee of the Non-Communicable Diseases, the Expert Committee on Disease Control and Prevention established by China's Ministry of Health in 2010, were invited to participate in an email-based, two-round Delphi survey. In each round, a structured questionnaire was given to participants, who were asked to rate the importance and practical implementation of items relevant to the prevention and control of NCDs over two periods, 1990–1999 and 2000–2009, on a 10-point scale. Results Of the 64 panellists invited, 20 (31.3%) completed the first-round survey, and, of those, 14 (70.0%) completed the second-round survey. Of the 237 common variables in the two survey rounds, there were 161 (67.9%) and 209 (88.2%) with an interquartile range ≤2 in the first round and second round, respectively. These results indicated a better expert consensus in the second round. There were 92 items in total in the second round of the questionnaire, 88 (95.7%) of which had median importance rating scores of equal to or greater than 7.00. The median scores for the practical implementation items during 2000–2009 were greater than those for the 1990–1999 period. The results indicate improved implementation in the recent decade. Conclusions China has made progress in the prevention and control of NCDs during the 21st century. However, these intuitive rating results indicate that there are still large action gaps in the fight against epidemic NCDs in China. PMID:23406920

    Background There is an ongoing discussion on the rising CS rate worldwide. Suboptimal guideline adherence may be an important contributor to this rise. Before improvement of care can be established, optimal CS care in different settings has to be defined. This study aimed to develop and measure quality indicators to determine guideline adherence and identify target groups for improvement of care with direct effect on caesarean section (CS) rates. Method Eighteen obstetricians and midwives participated in an expert panel for systematic CS quality indicator development according to the RAND-modified Delphi method. A multi-center study was performed and medical charts of 1024 women with a CS and a stratified and weighted randomly selected group of 1036 women with a vaginal delivery were analysed. Quality indicator frequency and adherence were scored in 2060 women with a CS or vaginal delivery. Results The expert panel developed 16 indicators on planned CS and 11 indicators on unplanned CS. Indicator adherence was calculated, defined as the number of women in a specific obstetrical situation in which care was performed as recommended in both planned and unplanned CS settings. The most frequently occurring obstetrical situations with low indicator adherence were: 1) suspected fetal distress (frequency 17%, adherence 46%), 2) non-progressive labour (frequency 12%, CS performed too early in over 75%), 3) continuous support during labour (frequency 88%, adherence 37%) and 4) previous CS (frequency 12%), with adequate counselling in 15%. Conclusions We identified four concrete target groups for improvement of obstetrical care, which can be used as a starting point to reduce CS rates worldwide. PMID:26783742

    The patients’ rights status is one of the essential elements in defining norms related to the concept of clinical governance system. In addition, the patients’ rights status is an important index for quality of care offered in the health care system. However, the lack of a coherent instrument makes it difficult to evaluate patients’ rights status in hospitals and clinics. The aim of this study was to develop an instrument for the evaluation of patients’ rights prerequisites at educational hospitals in Iran. This study was conducted using the modified Delphi technique. In this study, 36 experts in the fields of law, medicine, and professional ethics were participated. The panel of experts participated in 3 rounds. First, experts were asked to judge some pre-identified items, and then, excluded items were judged again in the second round. At the end of the third round, all of the agreed items were included in the final list to form an evaluative scale on practice of patients’ rights. Experts were asked to judge a total 171 items in 3 rounds. Around 31% (n = 53) of items obtained the panel’s approval to be included in the final version of the scale. The experts’ opinions were collected using face-to-face interviews and electronic email during a 6-month period of data collection from October 2013 to February 2014. This study developed a 53-item scale for evaluation of patients’ rights prerequisites in educational hospitals in Iran. This scale was developed in 7 areas of commitments including university education, research, supervision, process management, physical structure, organizational policy, and human resources management. This study developed an evaluative scale to assess the practice of patients’ rights in educational hospitals. The items in the final version of this scale were obtained from a consensus of experts and the instrument can be used to evaluate the context and prerequisites for practice of patients’ rights in Iranian educational

    This study compares a whole brain of the dwarf sperm whale (Kogia sima) with that of a common dolphin (Delphinus delphis) using high-resolution magnetic resonance imaging (MRI). The Kogia brain was scanned with a Siemens Trio Magnetic Resonance scanner in the three main planes. As in the common dolphin and other marine odontocetes, the brain of the dwarf sperm whale is large, with the telencephalic hemispheres remarkably dominating the brain stem. The neocortex is voluminous and the cortical grey matter thin but expansive and densely convoluted. The corpus callosum is thin and the anterior commissure hard to detect whereas the posterior commissure is well-developed. There is consistency as to the lack of telencephalic structures (olfactory bulb and peduncle, olfactory ventricular recess) and neither an occipital lobe of the telencephalic hemisphere nor the posterior horn of the lateral ventricle are present. A pineal organ could not be detected in Kogia. Both species show a tiny hippocampus and thin fornix and the mammillary body is very small whereas other structures of the limbic system are well-developed. The brain stem is thick and underlies a large cerebellum, both of which, however, are smaller in Kogia. The vestibular system is markedly reduced with the exception of the lateral (Deiters') nucleus. The visual system, although well-developed in both species, is exceeded by the impressive absolute and relative size of the auditory system. The brainstem and cerebellum comprise a series of structures (elliptic nucleus, medial accessory inferior olive, paraflocculus and posterior interpositus nucleus) showing characteristic odontocete dimensions and size correlations. All these structures seem to serve the auditory system with respect to echolocation, communication, and navigation. PMID:20203478

    Objective To explore areas of consensus and conflict in relation to perceived public involvement (PI) barriers and drivers, perceived impacts of PI and ways of evaluating PI approaches in health and social care research. Background Internationally and within the UK the recognition of potential benefits of PI in health and social care research is gathering momentum and PI is increasingly identified by organisations as a prerequisite for funding. However, there is relatively little examination of the impacts of PI and how those impacts might be measured. Design Mixed method, three-phase, modified Delphi technique, conducted as part of a larger MRC multiphase project. Sample Clinical and non-clinical academics, members of the public, research managers, commissioners and funders. Findings This study found high levels of consensus about the most important barriers and drivers to PI. There was acknowledgement that tokenism was common in relation to PI; and strong support for the view that demonstrating the impacts and value of PI was made more difficult by tokenistic practice. PI was seen as having intrinsic value; nonetheless, there was clear support for the importance of evaluating its impact. Research team cohesion and appropriate resources were considered essential to effective PI implementation. Panellists agreed that PI can be challenging, but can be facilitated by clear guidance, together with models of good practice and measurable standards. Conclusions This study is the first to present empirical evidence of the opinions voiced by key stakeholders on areas of consensus and conflict in relation to perceived PI barriers and drivers, perceived impacts of PI and the need to evaluate PI. As such it further contributes to debate around best practice in PI, the potential for tokenism and how best to evaluate the impacts of PI. These findings have been used in the development of the Public Involvement Impact Assessment Framework (PiiAF), an online resource which offers

    Objective There is growing interest in the potential benefits of public involvement (PI) in health and social care research. However, there has been little examination of values underpinning PI or how these values might differ for different groups with an interest in PI in the research process. We aimed to explore areas of consensus and conflict around normative, substantive and process-related values underpinning PI. Design Mixed method, three-phase, modified Delphi study, conducted as part of a larger multiphase project. Setting The UK health and social care research community. Participants Stakeholders in PI in research, defined as: clinical and non-clinical academics, members of the public, research managers, commissioners and funders; identified via research networks, online searches and a literature review. Results We identified high levels of consensus for many normative, substantive and process-related issues. However, there were also areas of conflict in relation to issues of bias and representativeness, and around whether the purpose of PI in health and social care research is to bring about service change or generate new knowledge. There were large differences by group in the percentages endorsing the ethical justification for PI and the argument that PI equalises power imbalances. With regard to practical implementation of PI, research support infrastructures were reported as lacking. Participants reported shortcomings in the uptake and practice of PI. Embedding PI practice and evaluation in research study designs was seen as fundamental to strengthening the evidence base. Conclusions Our findings highlight the extent to which PI is already embedded in research. However, they also highlight a need for ‘best practice’ standards to assist research teams to understand, implement and evaluate PI. These findings have been used in developing a Public Involvement Impact Assessment Framework (PiiAF), which offers guidance to researchers and members of the

    OBJECTIVES Barrett’s esophagus (BE) is a common premalignant lesion for which surveillance is recommended. This strategy is limited by considerable variations in clinical practice. We conducted an international, multidisciplinary, systematic search and evidence-based review of BE and provided consensus recommendations for clinical use in patients with nondysplastic, indefinite, and low-grade dysplasia (LGD). METHODS We defined the scope, proposed statements, and searched electronic databases, yielding 20,558 publications that were screened, selected online, and formed the evidence base. We used a Delphi consensus process, with an 80% agreement threshold, using GRADE (Grading of Recommendations Assessment, Development and Evaluation) to categorize the quality of evidence and strength of recommendations. RESULTS In total, 80% of respondents agreed with 55 of 127 statements in the final voting rounds. Population endoscopic screening is not recommended and screening should target only very high-risk cases of males aged over 60 years with chronic uncontrolled reflux. A new international definition of BE was agreed upon. For any degree of dysplasia, at least two specialist gastrointestinal (GI) pathologists are required. Risk factors for cancer include male gender, length of BE, and central obesity. Endoscopic resection should be used for visible, nodular areas. Surveillance is not recommended for <5 years of life expectancy. Management strategies for indefinite dysplasia (IND) and LGD were identified, including a de-escalation strategy for lower-risk patients and escalation to intervention with follow-up for higher-risk patients. CONCLUSIONS In this uniquely large consensus process in gastroenterology, we made key clinical recommendations for the escalation/de-escalation of BE in clinical practice. We made strong recommendations for the prioritization of future research. PMID:25869390

    Eutrophication and nutrient pollution of surface waters occur within complex governance, social, hydrologic and biophysical basin contexts. The pervasive and perennial nutrient pollution in Lake Champlain Basin, despite decades of efforts, exemplifies problems found across the world's surface waters. Stakeholders with diverse values, interests, and forms of explicit and tacit knowledge determine water quality impacts through land use, agricultural and water resource decisions. Uncertainty, ambiguity and dynamic feedback further complicate the ability to promote the continual provision of water quality and ecosystem services. Adaptive management of water resources and land use requires mechanisms to allow for learning and integration of new information over time. The transdisciplinary Research on Adaptation to Climate Change (RACC) team is working to build regional adaptive capacity in Lake Champlain Basin while studying and integrating governance, land use, hydrological, and biophysical systems to evaluate implications for adaptive management. The RACC team has engaged stakeholders through mediated modeling workshops, online forums, surveys, focus groups and interviews. In March 2014, CSS2CC.org, an interactive online forum to source and identify adaptive interventions from a group of stakeholders across sectors was launched. The forum, based on the Delphi Method, brings forward the collective wisdom of stakeholders and experts to identify potential interventions and governance designs in response to scientific uncertainty and ambiguity surrounding the effectiveness of any strategy, climate change impacts, and the social and natural systems governing water quality and eutrophication. A Mediated Modeling Workshop followed the forum in May 2014, where participants refined and identified plausible interventions under different governance, policy and resource scenarios. Results from the online forum and workshop can identify emerging consensus across scales and sectors

    Objectives To collect the views of experts to inform the development of an education package for multidisciplinary adult specialist palliative care (SPC) teams caring for young people with life-limiting conditions. Methods A modified online Delphi process collated expert opinion on format, delivery and content of an education package to up-skill adult SPC teams. Round 1 participants (n=44) answered free-text questions, generating items for Round 2. In Round 2, 68 participants rated the extent to which they agreed/disagreed with the items on 5-point Likert-type scales. Median and mean scores assessed the importance of each item. IQR scores assessed level of consensus for each item; items lacking consensus were rerated by 35 participants in Round 3. Results In the Delphi, consensus was reached on a range of suggested formats, on who should deliver the training, and on several clinical, psychosocial and practical topics. Conclusions Development of a continuous/rolling programme of education, tailored for content and mode of delivery and incorporated into working practice is recommended. As a direct outcome of the results of this study, a series of six linked study days has been established, focusing specifically on the issues around caring for young adults with life-limiting conditions and palliative care needs.

    The current consensus on the diagnosis, prognosis, and treatment of essential thrombocythemia (ET) is based on experts' recommendations. However, several aspects of the diagnosis of, prognosis of, and therapy for ET are still controversial. The Delphi method was employed with an expert panel of members of the Spanish Group of Ph-negative Myeloproliferative Neoplasms in order to identify the degree of agreement on the diagnosis, prognosis, and treatment of ET. Nine leading experts selected a total of 41 clinical hematologists with well-known expertise in ET. An electronic questionnaire was used to collect the questions rated in a four-step scale. The questions were grouped into four blocks: diagnosis, risk stratification, goals of therapy, and treatment strategy. After the first round consisting of 80 questions, a second round including 14 additional questions focused on the recommendations advocated by experts of the European LeukemiaNet in 2011 was analyzed. The median and mean values for the first and second rounds were calculated. A summary of the conclusions considered as the most representative of each block of questions is presented. The Delphi method is a powerful instrument to address the current approaches and controversies surrounding ET. PMID:26898207

  12. Consensus on items and quantities of clinical equipment required to deal with a mass casualties big bang incident: a national Delphi study

    PubMed Central

    2014-01-01

    Background Major short-notice or sudden impact incidents, which result in a large number of casualties, are rare events. However health services must be prepared to respond to such events appropriately. In the United Kingdom (UK), a mass casualties incident is when the normal response of several National Health Service organizations to a major incident, has to be supported with extraordinary measures. Having the right type and quantity of clinical equipment is essential, but planning for such emergencies is challenging. To date, the equipment stored for such events has been selected on the basis of local clinical judgment and has evolved without an explicit evidence-base. This has resulted in considerable variations in the types and quantities of clinical equipment being stored in different locations. This study aimed to develop an expert consensus opinion of the essential items and minimum quantities of clinical equipment that is required to treat 100 people at the scene of a big bang mass casualties event. Methods A three round modified Delphi study was conducted with 32 experts using a specifically developed web-based platform. Individuals were invited to participate if they had personal clinical experience of providing a pre-hospital emergency medical response to a mass casualties incident, or had responsibility in health emergency planning for mass casualties incidents and were in a position of authority within the sphere of emergency health planning. Each item’s importance was measured on a 5-point Likert scale. The quantity of items required was measured numerically. Data were analyzed using nonparametric statistics. Results Experts achieved consensus on a total of 134 items (54%) on completion of the study. Experts did not reach consensus on 114 (46%) items. Median quantities and interquartile ranges of the items, and their recommended quantities were identified and are presented. Conclusions This study is the first to produce an expert consensus on the

    Kelley, Jean Mary

    The purpose of this study was to identify, analyze, and compare the perceptions of selected district science educators and teachers of middle school science students regarding the following issues: (1) Current methods of differentiating science instruction for gifted middle school students. (2) Strengths of the current methods of differentiating science instruction for gifted middle school students. (3) Weaknesses of the current methods of differentiating science instruction for gifted middle school students. (4) The types of training/experience needed to prepare teachers to effectively differentiate science instruction for gifted middle school students. (5) The steps need to develop an effective differentiated science program at the middle school level. (6) Trends for the future development of differentiated science programs at the middle school level. The panel of educators was identified using the Delphi technique and asked to participate in the study by responding to the research questions. The responses to the first round were condensed into two lists of discrete statements, and in the second round, each group of panelists was asked to rank each statement on a Likert scale. A third round was sent to each group of panel members showing the median and interquartile ranges of the second round. Panelists could adjust their responses based on the results of the second round. The analysis of the data was computed using the computer program Statistics Package for the Social Sciences. Based on the data obtained, the following results and conclusions were determined. The coordinators and the teachers both considered training of teachers, strategies for differentiation, and future trends to be the most important considerations. The areas with the most differences were those dealing with the current methods of differentiating science instruction at the middle school level. There were several limitations identified in this study. Among them were the makeup of the sample

    2011-01-01

    Background European Member States are facing a challenge to provide accessible and effective health care services for immigrants. It remains unclear how best to achieve this and what characterises good practice in increasingly multicultural societies across Europe. This study assessed the views and values of professionals working in different health care contexts and in different European countries as to what constitutes good practice in health care for immigrants. Methods A total of 134 experts in 16 EU Member States participated in a three-round Delphi process. The experts represented four different fields: academia, Non-Governmental Organisations, policy-making and health care practice. For each country, the process aimed to produce a national consensus list of the most important factors characterising good practice in health care for migrants. Results The scoring procedures resulted in 10 to 16 factors being identified as the most important for each participating country. All 186 factors were aggregated into 9 themes: (1) easy and equal access to health care, (2) empowerment of migrants, (3) culturally sensitive health care services, (4) quality of care, (5) patient/health care provider communication, (6) respect towards migrants, (7) networking in and outside health services, (8) targeted outreach activities, and (9) availability of data about specificities in migrant health care and prevention. Although local political debate, level of immigration and the nature of local health care systems influenced the selection and rating of factors within each country, there was a broad European consensus on most factors. Yet, discordance remained both within countries, e.g. on the need for prioritising cultural differences, and between countries, e.g. on the need for more consistent governance of health care services for immigrants. Conclusions Experts across Europe asserted the right to culturally sensitive health care for all immigrants. There is a broad consensus

    Teare, Matthew Alan

    The purpose of this study was to identify perceptions of successful methods, experiences and curriculum used within science teacher preparation programs. Three general questions drove this study: (1) What combination of information, experiences and curriculum within a science teacher education program is thought to assist future teachers with developing the expertise required to be successful in urban settings? (2) What issues that have an impact on urban education do the participants feel should/should not be addressed within a science teacher education program? (3) What resources and support do science education faculty members require in order to enhance their effectiveness in preparing preservice teachers for careers in urban settings? The twenty participants consisted of professors who taught preservice education methods courses at urban universities. The participants' demographic and background information showed that all the participants had sufficient knowledge, experience and were able to apply their knowledge to this research study, making them all experts. The selection of the twenty experts started by identifying fifty urban school districts based on a combination of enrollment and poverty rate within the United States. To keep the geographic range of universities widespread, no university had more than one participant. A conscious effort was made to recruit females and minorities as panelists. Out of the twenty panelists 2 were African-American, 1 was Asian, 12 were female and 8 were male. The Delphi technique was used as a means of communication between the twenty participants and the researcher. Three rounds of questionnaires were mailed to the participants. Each round consisted of issue statements and open-ended questions addressing topics hypothesized to be of potential importance to the science teacher education programs. The issue statements and open-ended questions within Round One were developed based on the literature review in Chapter II. The

    Background Despite research supporting the use of care coordination in chronic obstructive pulmonary disease (COPD), there is relatively little known about the comparative effectiveness of different strategies used to organize care for patients. To investigate the most important COPD care coordination strategies, community-based stakeholder input is needed, especially from medically underserved populations. Web-based platforms are electronic tools now being used to bring together individuals from underrepresented populations to share input and obtain clarification on comparative effectiveness research (CER) ideas, questions, and hypotheses. Objective Use low computer-literate, collaborative survey technology to evaluate stakeholder priorities for CER in COPD care coordination. Methods A mixed-method, concurrent triangulation design was used to collect survey data from a virtual advisory board of community-based stakeholders including medically underserved patients with COPD, informal caregivers, clinicians, and research scientists. The eDelphi method was used to conduct 3 iterative rounds of Web-based surveys. In the first 2 survey rounds, panelists viewed a series of “mini research prospectus” YouTube video presentations and rated their level of agreement with the importance of 10 COPD care coordination topics using 7-point Likert scales. In the final third-round survey, panelists ranked (1=most important, 8=least important) and commented on 8 remaining topics that panelists favored most throughout the first 2 survey rounds. Following the third-round survey, panelists were asked to provide feedback on the potential impact of a Web-based stakeholder engagement network dedicated to improving CER in COPD. Results Thirty-seven panelists rated the following care coordination topics as most important (lower means indicate greater importance): (1) measurement of quality of care (mean 2.73, SD 1.95); (2) management of COPD with other chronic health issues (mean 2

    2008-01-01

    Background The Internet is an attractive medium for delivering individualized, computer-tailored behavior change interventions to large numbers of people. However, the actual numbers of people reached seem to fall behind the high expectations. Insight into factors that determine use of and exposure to these Internet interventions is important to be able to increase the reach and improve exposure. Objective The aim was to identify potentially important factors that determine whether adults visit an Internet-delivered behavior change intervention, extend their visit, and revisit the intervention. Methods A systematic, three-round Delphi study was conducted among national and international experts from Internet intervention research and practice, e-marketing/e-commerce, Web design, and technical website development. In the first round, 30 experts completed a structured, open-ended online questionnaire assessing factors that were, in their opinion, important for a first visit, an extended visit, a revisit and for effective promotion strategies. Based on the responses in this first questionnaire, a closed-ended online questionnaire was developed for use in the second round. A total of 233 experts were invited to complete this questionnaire. Median and interquartile deviation (IQD) scores were computed to calculate agreement and consensus on the importance of the factors. The factors for which no consensus was obtained (IQD > 1) were included in the third-round questionnaire. Factors with a median score of six or higher and with an IQD ≤ 1 were considered to be important. Results Of the 62 experts invited for the first round, 30 completed the questionnaire (48% response rate); 93/233 experts completed the second-round questionnaire (40% response rate), and 59/88 completed the third round (67% response rate). Being motivated to visit an Internet intervention and perceiving the intervention as personally relevant appeared to be important factors related to a first visit

    Background Exercise is recommended for people with an acute exacerbation of chronic obstructive pulmonary disease (AECOPD), yet there is little information to guide safe and effective mobilization and exercise for these patients. Objectives The purpose of this study was to develop a clinical decision-making tool to guide health care professionals in the assessment, prescription, monitoring, and progression of mobilization and therapeutic exercise for patients with AECOPD. Design and Methods A 3-round interdisciplinary Delphi panel identified and selected items based on a preselected consensus of 80%. These items were summarized in a paper-based tool titled Mobilization in Acute Exacerbations of Chronic Obstructive Pulmonary Disease (AECOPD-Mob). Focus groups and questionnaires were subsequently used to conduct a sensibility evaluation of the tool. Results Nine researchers, 13 clinicians, and 7 individuals with COPD identified and approved 110 parameters for safe and effective exercise in AECOPD. These parameters were grouped into 5 categories: (1) “What to Assess Prior to Mobilization,” (2) “When to Consider Not Mobilizing or to Discontinue Mobilization,” (3) “What to Monitor During Mobilization for Patient Safety,” (4) “How to Progress Mobilization to Enhance Effectiveness,” and (5) “What to Confirm Prior to Discharge.” The tool was evaluated in 4 focus groups of 18 health care professionals, 90% of whom reported the tool was easy to use, was concise, and would guide a health care professional who is new to the acute care setting and working with patients with AECOPD. Limitations The tool was developed based on published evidence and expert opinion, so the applicability of the items to patients in all settings cannot be guaranteed. The Delphi panel consisted of health care professionals from Canada, so items may not be generalizable to other jurisdictions. Conclusions The AECOPD-Mob provides practical and concise information on safe and

    The IC(4) software developed to compare calculated internal conversion coefficients (ICC) has been enhanced by adding new features through the use of Borland Delphi and TeeChart. Particularly, the 3D-graph option enhances the possibilities of analyzing calculated ICC values. For example, the comparison between the results given by three sets of theoretical ICC tables for any arbitrary pair of calculated ICC can be presented in a much clearer manner. Their differences can be displayed as energy vs. atomic number surfaces. Results from the analyses of K-shell and total ICCs for E2, E3, M2, M3, and M4 multipolarity are discussed. PMID:11839014

    Microsoft's Visual Basic (VB) and Borland's Delphi provide an extremely robust programming environment for delivering multimedia solutions for interactive kiosks, games and titles. Their object oriented use of standard and custom controls enable a user to build extremely powerful applications. A multipurpose, database enabled programming environment that can provide an event driven interface functions as a multimedia kernel. This kernel can provide a variety of authoring solutions (e.g. a timeline based model similar to Macromedia Director or a node authoring model similar to Icon Author). At the heart of the kernel is a set of low level multimedia components providing object oriented interfaces for graphics, audio, video and imaging. Data preparation tools (e.g., layout, palette and Sprite Editors) could be built to manage the media database. The flexible interface for VB allows the construction of an infinite number of user models. The proliferation of these models within a popular, easy to use environment will allow the vast developer segment of 'producer' types to bring their ideas to the market. This is the key to building exciting, content rich multimedia solutions. Microsoft's VB and Borland's Delphi environments combined with multimedia components enable these possibilities.

    2005-01-01

    Objective: An expert consensus on the future of the library as place was developed to assist health sciences librarians in designing new library spaces. Method: An expert panel of health sciences librarians, building consultants, architects, and information technologists was asked to reflect on the likelihood, desirability, timing, and impact on building design of more than seventy possible changes in the use of library space. Results: An expert consensus predicted that the roles librarians play and the way libraries are used will substantially change. These changes come in response to changes in technology, scholarly communication, learning environments, and the health care economy. Conclusions: How health sciences library space is used will be far less consistent by 2015, as space becomes more tailored to institutional needs. However, the manner in which health sciences libraries develop and deliver services and collections will drastically change in the next decade. Libraries will continue to exist and will provide support for knowledge management and clinical trials, provide access to digital materials, and play a host of other roles that will enable libraries to emerge as institutional change agents.

  17. Predicting Nonspecific Ion Binding Using DelPhi

    2012-01-01

    Ions are an important component of the cell and affect the corresponding biological macromolecules either via direct binding or as a screening ion cloud. Although some ion binding is highly specific and frequently associated with the function of the macromolecule, other ions bind to the protein surface nonspecifically, presumably because the electrostatic attraction is strong enough to immobilize them. Here, we test such a scenario and demonstrate that experimentally identified surface-bound ions are located at a potential that facilitates binding, which indicates that the major driving force is the electrostatics. Without taking into consideration geometrical factors and structural fluctuations, we show that ions tend to be bound onto the protein surface at positions with strong potential but with polarity opposite to that of the ion. This observation is used to develop a method that uses a DelPhi-calculated potential map in conjunction with an in-house-developed clustering algorithm to predict nonspecific ion-binding sites. Although this approach distinguishes only the polarity of the ions, and not their chemical nature, it can predict nonspecific binding of positively or negatively charged ions with acceptable accuracy. One can use the predictions in the Poisson-Boltzmann approach by placing explicit ions in the predicted positions, which in turn will reduce the magnitude of the local potential and extend the limits of the Poisson-Boltzmann equation. In addition, one can use this approach to place the desired number of ions before conducting molecular-dynamics simulations to neutralize the net charge of the protein, because it was shown to perform better than standard screened Coulomb canned routines, or to predict ion-binding sites in proteins. This latter is especially true for proteins that are involved in ion transport, because such ions are loosely bound and very difficult to detect experimentally. PMID:22735539

    PubMed

    Zhang, Fuqiang

    2006-09-15

    Operant behavioral researches require precise control of experimental devices for delivering stimuli and monitoring behavioral responses. The author developed a software solution named SuperState for controlling hardware devices and running reinforcement schedules. The Microsoft Windows compatible software was written by use of an object-oriented programming language Borland Delphi 5.0, which has simplified the programming of the application. SuperState is a stand-alone easy-to-use green software, without the need for the experimenter to master any scripting languages. It features: (1) control of multiple operant cages running independent reinforcement schedules; (2) enough cage devices (16 digital inputs and 16 digital outputs for each cage) suitable for the need of most operant behavioral equipments; (3) control of most standard ISA-type digital interface cards including Med-Associates Super-port cards and a PCI-type card AC6412, and highly expandable to support other PCI-type interface cards; (4) high-resolution device control (1ms); (5) a built-in real-time cumulative recorder; (6) extensive data analyzing including event recorder, cumulative recorder, block analyzing; the summarized results can be transferred easily to Microsoft Excel spreadsheets through the Clipboard.

    Post-Scan Interactive Data Display (PSIDD) III is a user-oriented Windows-based system that facilitates the display and comparison of ultrasonic contact measurement data obtained at NASA Glenn Research Center's Ultrasonic Nondestructive Evaluation measurement facility. The system is optimized to compare ultrasonic measurements made at different locations within a material or at different stages of material degradation. PSIDD III provides complete analysis of the primary waveforms in the time and frequency domains along with the calculation of several frequency-dependent properties including phase velocity and attenuation coefficient and several frequency-independent properties, like the cross correlation velocity. The system allows image generation on all the frequency-dependent properties at any available frequency (limited by the bandwidth used in the scans) and on any of the frequency-independent properties. From ultrasonic contact scans, areas of interest on an image can be studied with regard to underlying raw waveforms and derived ultrasonic properties by simply selecting the point on the image. The system offers various modes of indepth comparison between scan points. Up to five scan points can be selected for comparative analysis at once. The system was developed with Borland Delphi software (Visual Pascal) and is based on an SQL data base. It is ideal for the classification of material properties or the location of microstructure variations in materials. Along with the ultrasonic contact measurement software that it is partnered with, this system is technology ready and can be transferred to users worldwide.

    2013-01-01

    A female short-beaked common dolphin calf was found stranded in San Diego, California in October 2010, presenting with multifocal ulcerative lesions in the trachea and bronchi. Viral particles suggestive of polyomavirus were detected by EM, and subsequently confirmed by PCR and sequencing. Full genome sequencing (Ion Torrent) revealed a circular dsDNA genome of 5,159 bp that was shown to form a distinct lineage within the genus Polyomavirus based on phylogenetic analysis of the early and late transcriptomes. Viral infection and distribution in laryngeal mucosa was characterised using in-situ hybridisation, and apoptosis observed in the virus-infected region. These results demonstrate that polyomaviruses can be associated with respiratory disease in cetaceans, and expand our knowledge of their diversity and clinical significance in marine mammals.

  11. The future of practical skills in undergraduate medical education – an explorative Delphi-Study

    PubMed Central

    Dannenberg, Katja Anne; Stroben, Fabian; Schröder, Therese; Thomas, Anke; Hautz, Wolf E.

    2016-01-01

    Background: 64% of young medical professionals in Germany do not feel adequately prepared for the practical requirements of the medical profession. The goal of “outcome-orientated training” is to structure medical curricula based on the skills needed when entering the workforce after completing undergraduate medical education, and thus to bridge the gap between the skills graduates have attained and those necessary for a career in the medical profession. Outcome frameworks (OFs) are used for this purpose. In preparation for developing the National Competence-Based Catalogue of Learning Objectives for Medicine (NKLM) – the German OF – the “Consensus Statement of Practical Skills in Undergraduate Medical Education” (which structures the teaching and acquisition of practical skills in Germany and which strongly influenced the “Clinical-Practical Skills” chapter of the NKLM) was published in 2011. It is not uncommon for at least a decade to elapse between the definition and implementation of an OF and the students’ graduation, which can further increase the gap between necessary and acquired skills. Thus, the purpose of this paper is to posit theses for future development in healthcare and to apply these theses to a current OF. Methodology: Partially structured interviews with experts were used to generate theses pertaining to general, future development in healthcare. These theses were assessed by physician experts based on the likelihood of implementation by the year 2025. The 288 learning goals of the consensus statement were assessed for their relevance for medical education in the interim. Results: 11 theses were generated for the development of medicine, and these theses were assessed and discussed by 738 experts. These theses include the increase in diseases associated with old age, the increasing significance of interprofessional cooperation, and the growing prevalence of telemedicine applications. Of the 288 learning goals of the consensus statement, 231 of the goals were assessed as relevant, and 57 were deemed irrelevant for the short-term future. Discussion: The theses on the future of healthcare, which were generated in this study and which were validated by numerous experts, provide indications of future developments of overall requirements for medical school graduates. For example, when applied to the content of the “Clinical-Practical Skills” NKLM chapter, they largely validate the future relevance of developing practical skills while also providing indications for their further development as applied to the consensus statement.

    The polarization of {tau} leptons produced in the reaction e{sup +}e{sup {minus}} {yields} {tau}{sup +}{tau}{sup {minus}} near the peak of the Z{degree} resonance has been measured using a sample of 24904 {tau}{sup +}{tau}{sup {minus}} events, with an estimated background of 1.5%. We have selected 4562 {tau} {yields} e{nu}{bar {nu}} 2218 {tau} {yields} {pi}{nu} and 5133 {tau} {yields} {rho}{nu} candidates. The mean value obtained is P{sub {tau}} = {minus}0.176 {plus_minus} 0.029. This corresponds to a ratio of the neutral current vector to the axial-vector coupling constants of the {tau} lepton of g{sub V}{sup {tau}}/g{sub A}{sup {tau}} = 0.088 {plus_minus} 0.014. This leads to a value of the electroweak mixing angle of sin{sup 2}{theta}{sub W} = 0.2280 {plus_minus} 0.0036. This result is in good agreement with previous measurements of the weak mixing angle from the study of the Z{degree} lineshape and the forward-backward asymmetries in the processes Z{degree} {yields} l{sup +}l{sup {minus}} and Z{degree} {yields} q{bar q}.

    2016-01-01

    Cancer clinical trials (ccts) are essential for furthering knowledge and developing effective interventions to improve the lives of people living with cancer in Canada. Randomized controlled trials are particularly important for developing evidence-based health care interventions. To produce robust and relevant research conclusions, timely and sufficient accrual to ccts is essential. The present report delivers the key recommendations emerging from a workshop meeting, Improve Accrual to Cancer Clinical Trials, that was hosted by the Canadian Cancer Trials Group and funded by the Canadian Institutes of Health Research. The meeting, which took place in Toronto, Ontario, in April 2012 before the Canadian Cancer Trials Group annual spring meeting, brought together key stakeholders from across Canada to explore creative strategies for improving accrual to ccts. The objectives of the workshop were to provide an opportunity for knowledge exchange with respect to the research evidence and the ethics theory related to cct accrual and to promote discussion of best practices and policies related to enhancing cct access and accrual in Canada. The workshop provided the foundation for establishing new interdisciplinary research collaborations to overcome the identified barriers to cct participation in Canada. Meeting participants also supported the development of evidence-based policies and practices to make trials more accessible to Canadians living with cancer.

    2010-01-01

    In an effort to foster research integrity, the National Institutes of Health and the National Science Foundation mandate education of all trainees in the responsible conduct of research (RCR). Nevertheless, recent studies suggest that rates of questionable research practices and scientific misconduct are both high and considerably underreported. In part, this may be due to the fact that some ethical norms (e.g., authorship assignment) are far from clear and researchers are unsure how to respond to perceived misconduct. With funding from the U.S. Office of Research Integrity (ORI), we convened four panels of experts to develop a consensus on the overarching goals and teaching content of RCR instruction. Our panelists recommended nine overarching objectives for RCR instruction that require us to rethink common modes of instruction, and they identified issues and standards that should be covered within controversial areas such as authorship assignment and whistle-blowing. Additionally, our experts recommended two new core areas for RCR instruction: The social responsibilities of scientists and current topics in RCR. PMID:22500145

  16. NCWin - A Component Object Model (COM) for processing and visualizing NetCDF data

    USGS Publications Warehouse

    Liu, J.; Chen, J.M.; Price, D.T.; Liu, S.

    2005-01-01

    NetCDF (Network Common Data Form) is a data sharing protocol and library that is commonly used in large-scale atmospheric and environmental data archiving and modeling. The NetCDF tool described here, named NCWin and coded with Borland C+ + Builder, was built as a standard executable as well as a COM (component object model) for the Microsoft Windows environment. COM is a powerful technology that enhances the reuse of applications (as components). Environmental model developers from different modeling environments, such as Python, JAVA, VISUAL FORTRAN, VISUAL BASIC, VISUAL C+ +, and DELPHI, can reuse NCWin in their models to read, write and visualize NetCDF data. Some Windows applications, such as ArcGIS and Microsoft PowerPoint, can also call NCWin within the application. NCWin has three major components: 1) The data conversion part is designed to convert binary raw data to and from NetCDF data. It can process six data types (unsigned char, signed char, short, int, float, double) and three spatial data formats (BIP, BIL, BSQ); 2) The visualization part is designed for displaying grid map series (playing forward or backward) with simple map legend, and displaying temporal trend curves for data on individual map pixels; and 3) The modeling interface is designed for environmental model development by which a set of integrated NetCDF functions is provided for processing NetCDF data. To demonstrate that the NCWin can easily extend the functions of some current GIS software and the Office applications, examples of calling NCWin within ArcGIS and MS PowerPoint for showing NetCDF map animations are given. ??

  17. A computer program for the simulation of folds of different sizes under the influence of gravity

    NASA Astrophysics Data System (ADS)

    Vacas Peña, José M.; Martínez Catalán, José R.

    2004-02-01

    Folding&g is a computer program, based on the finite element method, developed to simulate the process of natural folding from small to large scales in two dimensions. Written in Pascal code and compiled with Borland Delphi 3.0, the program has a friendly interactive user interface and can be used for research as well as educational purposes. Four main menu options allow the user to import or to build and to save a model data file, select the type of graphic output, introduce and modify several physical parameters and enter the calculation routines. The program employs isoparametric, initially rectangular elements with eight nodes, which can sustain large deformations. The mathematical procedure is based on the elasticity equations, but has been modified to simulate a viscous rheology, either linear or of power-law type. The parameters to be introduced include either the linear viscosity, or, when the viscosity is non-linear, the material constant, activation energy, temperature and power of the differential stress. All the parameters can be set by rows, which simulate layers. A toggle permits gravity to be introduced into the calculations. In this case, the density of the different rows must be specified, and the sizes of the finite elements and of the whole model become meaningful. Viscosity values can also be assigned to blocks of several rows and columns, which permits the modelling of heterogeneities such as rectangular areas of high strength, which can be used to simulate shearing components interfering with the buckling process. The program is applied to several cases of folding, including a single competent bed and multilayers, and its results compared with analytical and experimental results. The influence of gravity is illustrated by the modelling of diapiric structures and of a large recumbent fold.
