To provide local policymakers with a guideline of potential actions to prevent the high consumption of Non-Nutritive Sweeteners (NNS) among children and adolescents observed in Chile, given the potential health problems related to NNS intake.

The Delphi method was used for the evaluation of twenty-one recommendations to decrease the intake of NNS in paediatric population, with the participation of a panel of relevant actors.

The proposed recommendations were developed by the research team using the NOURISHING framework; potential actions were based on the increase in the use and intake of NNS by Chilean children, current local food regulations, recommendations of health organisations and foreign policy experiences.

Twenty-five relevant actors related to NNS, nutrition, food technology and paediatrics (out of thirty-nine invitations made to scholars, professional institutions and civil society’s organisations) participated in the Delphi study.

A consensus was reached on nine recommendations regarding relevance and feasibility to be part of the guideline. Recommendations involved measures mostly related to improving the delivery of information (food content and potential health effects of NNS), supporting the generation of more evidence of NNS health effects and substitutes, and marketing restrictions when targeted to children.

The process produced a nine-action guideline to reduce the excessive NNS consumption among Chilean children and adolescents. Developed through a consensus-driven approach among key stakeholders, this guideline provides policymakers with a framework to adopt a precautionary stance, particularly concerning vulnerable populations, given the currently inconclusive evidence on the long-term health effects of NNS consumption.

The aim of this study is to develop a post-stroke home care checklist for the use of primary care professionals.

Home care is an integral part of primary health care. In the literature, several scales are available to help determine elderly individuals’ need for home care services; however, there are no standard care criteria or guidelines for the home care of stroke survivors. Therefore, a standardized post-stroke home care tool specific for use by primary care professionals is needed to identify patients’ needs and to detect intervention areas.

This is a checklist development study carried out between December 2017 and September 2018 in Turkey. A modified Delphi technique was used. In the first stage of the study, a literature review was carried out, a workshop was conducted with healthcare specialists in the stroke area, and a 102-item draft checklist was created. In the second stage, two written Delphi rounds were carried out via email with 16 healthcare professionals providing post-stroke home care. In stage three, the agreed items were reviewed, and similar items were grouped together to create the final checklist.

A consensus was achieved in 93 of the 102 items. The final checklist, consisting of four main themes and 15 headings, was created. The four main areas of assessment in post-stroke home care are ‘assessment of current status’, ‘identification of risks’, ‘evaluation of the care environment and caregiver’, and ‘planning follow-up care’. The Cronbach alpha reliability coefficient of the checklist was found to be 0.93. In conclusion, the PSHCC-PCP is the first checklist created to be used by primary care professionals in post-stroke home care. However, it needs to be assessed in terms of effectiveness and usefulness with further studies.

The main objective of this research was to generate a consensus on the conceptual definition of household emergency preparedness from experts representing multiple disciplines and countries, in order to facilitate the development of an all-hazards, comprehensive, valid, and reliable instrument.

Questions were generated via 3 methods: literature search, using existing instruments, and expert panels using the Delphi technique.

Panelists (n = 154) representing 36 countries came to a consensus that household emergency preparedness is defined as the completion of several preparedness actions and assembling a kit that can be transported in an evacuation. The new 51-question instrument demonstrates face, content, and criterion validity and internal consistency reliability (α = 0.96). The instrument assesses whether specific preparedness actions have been taken, and the presence or absence of essential supplies that could enable households to safely endure conditions that disasters would likely present (loss of power, water limitations, and/or lack of access to additional supplies for a few days).

A valid and reliable instrument provides researchers with a replicable approach to assessment of preparedness levels, which is necessary to plan mitigation strategies, enhance health promotion, prevent injuries, and increase resilience for individuals and communities. The instrument can provide evidence to support interventions addressing health needs of community members following a disaster.

Promoting a traditional Mexican diet (TMexD) could potentially reduce high rates of non-communicable diseases (NCD) and support food sustainability in Mexico. This study aimed to develop an index to assess adherence to the TMexD.

A three-round Delphi study was conducted to examine the food groups, specific foods and food-related habits that would constitute a TMexD index. Participants selected the TMexD items using Likert scales, lists of responses, and yes/no questions. Consensus was determined using percentages of agreement, mean values and/or coefficients of variation.

Online Delphi study.

Seventeen nutrition and food experts in Mexico completed all three rounds.

The resulting index (ranging from 0 to 21 points) consisted of 15 food groups, containing 102 individual foods. Food groups included in higher quantities were maize, other grains, legumes, vegetables, fruits, herbs, nuts and seeds, and tubers. Animal foods, vegetable fats and oils, homemade beverages, maize-based dishes, and plain water were also included, but in lower quantities. The food-related habits included were consuming homemade meals, socialising at meals and buying food in local markets. Consensus was reached for all index items apart from quantities of consumption of six food groups (herbs, nuts, grains, tubers, dairy and eggs).

Although future research could improve the measures for which consensus was not reached, the TMexD index proposed in this study potentially displays a healthy and sustainable dietary pattern and could be used to examine links between the TMexD and health outcomes in Mexican populations.

Schematherapy (ST) is an effective therapy for personality disorders (PD's) in adults, however, empirical research into ST in older adults is limited. The manifestation of schemas over the life course is unclear. Besides, long-term patterns of schemas in old age and whether schemas change during the aging process remain unknown.

We performed a Delphi study involving a group meeting of nine experts in the field of ST in older adults.

Full consensus was achieved that schemas vary later in life, and that this is due to biopsychosocial factors. The concepts of schema triggering (the chance that a maladaptive schema is activated) and schema coping (the psychological and behavioral effort a person makes to minimize the stress that comes with the schema) in the past are important in clinical practice. Understanding how schemas are triggered during the life course and how patients deal with their schemas throughout life will help the therapist to complete the diagnostic puzzle in older individuals and to choose appropriate interventions.

Schemas are flexible and dynamic constructs that can fade or intensify due to multiple factors. This study is a first step toward advancing the state of knowledge regarding schema theory in an aging population. The results will contribute to improvements in ST in older adults by developing an understanding of the plasticity of schemas during the life course.

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).

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%).

Event health stakeholders require sound data upon which to build a robust MGH evidence-base. The move towards standardization of data points and/or reporting items of interest will strengthen the development of such an evidence-base from which governments, researchers, clinicians, and event planners could benefit. There is substantial agreement on some broad concepts underlying MGH amongst an international group of MG experts. Refinement is needed regarding an overall conceptual diagram and proposed matrix for organizing data elements.

Palliative care research is relatively diverse and prioritizing research in this field is dependent on multiple factors such as complex ethical decisions in designing and conducting the research; access to participants who may be deemed “vulnerable” and an increasingly medically focused approach to care. The aim of this study was to inform organizational decision-making and policy development regarding future research priorities for a hospice service in New Zealand.

A modified three-round Delphi technique was employed. Participants were drawn from one dedicated specialist palliative care service that delivers care in the community, day-care, hospice inpatient, aged residential care, and acute hospital palliative care service. A purposive sample included palliative care staff (n = 10, 18, 9, for rounds 1–3, respectively) volunteers (n = 10, 12, 11); and patients and family carers (n = 6, 8, for rounds 1 and 2). Patients and family carers were not involved in the third round.

At final ranking of six research themes encompassing 23 research topics were identified by staff and volunteers. These were: symptom management; aged care; education; community; patient and family; and bereavement support and young people. Patients and family carers agreed on four themes, made up of 10 research topics. These were: decision-making, bereavement and loss, symptom management; and recognition of need and response of service.

The study generated a rich set of research themes and specific research topics. The perspectives of staff and volunteers are significantly different from those of patients and family members, in spite of the recognition by all concerned that palliative care services work within a philosophy of patient-centered care. Open discussion of ideas has the potential to engage both staff and patients and carers in quality improvement initiatives, and to reinforce the value of research for patient care.

To assess key experts’ opinion regarding essential competencies required for effective public health nutrition practice within the health-care system of Iran.

Qualitative study using the modified Delphi technique through an email-delivered questionnaire.

Iran.

Fifty-five experts were contacted through email. The inclusion criterion for the study panel was being in a relevant senior-level position in nutrition science or public health nutrition in Iran.

In the first round, forty-two out of fifty-five experts responded to the questionnaire (response rate=76 %). A sixty-five-item questionnaire was designed with nine competency areas, including ‘nutrition science’, ‘planning and implementing nutritional interventions’, ‘health and nutrition services’, ‘advocacy and communication’, ‘assessment and analysis’, ‘evaluation’, ‘cultural, social and political aspects’, ‘using technology’ and ‘leadership and management’. All experts who had participated in the first round completed a modified version of the questionnaire with seventy-seven items in the second round. The experts scored ‘nutrition science’ as the most essential competency area, while more applied areas such as ‘management and leadership’ were less emphasized. In both rounds, the mean difference between the opinions of the necessity of each area was 5·6 %.

The Iranian experts had general agreement on most of the core competency areas of public health nutritionists. The results indicated the need for capacity building and revisions to educational curricula for public health nutritionist programmes, with more emphasis on skill-based competency development.

To collate the opinions of experts and to reach consensus about the research priorities in the management of major incidents.

A three-round e-Delphi study was conducted using an international panel of experts drawn from active researchers and active educators in major incident management. General areas for consideration were derived from the literature analysis undertaken as part of the overall project.

Experts generated 221 statements in 11 topic areas in the first round. Fifty-one of these statements reached consensus in Round 2. A further 23 statements reached consensus in Round 3, leaving 147 statements that did not reach consensus.

An international expert panel reached consensus on 74 topics of research priority in major incidents management. The strongest themes within these topics were education and training, planning, and communication.

To identify the level of consensus among a group of Canadian emergency department (ED) experts on the importance of a set of indicators to document ED overcrowding.

A 2-round Delphi survey was conducted from February 2005 to April 2005, with a multi-disciplinary group of 38 Canadian experts in various aspects of ED operations who rated the relevance of 36 measures and ranked their relative importance as indicators of ED overcrowding.

The response rates for the first and second rounds were 84% and 87%, respectively. The most important indicator identified by the experts was the percentage of the ED occupied by in-patients (mean on a 7-point Likert-type scale 6.53, standard deviation [SD] 0.80). The other 9 indicators, in order of the importance attributed, were the total number of ED patients (mean 6.35, SD 0.75), the total time in the ED (mean 6.16, SD 1.04), the percentage of time that the ED was at or above capacity (mean 6.16, SD 1.08), the overall bed occupancy (mean 6.19, SD 0.93), the time from bed request to bed assignment (mean 6.06, SD 1.08), the time from triage to care (mean 5.84, SD 1.08) the physician satisfaction (mean 5.84, SD 1.22), the time from bed availability to ward transfer (mean 5.53, SD 1.72) and the number of staffed acute care beds (mean 5.53, SD 1.57).

Ten clinically important measures were prioritized by the participants as relevant indicators of ED overcrowding. Indicators derived from consensus techniques have face validity, but their metric properties must be tested to ensure their effectiveness for identifying ED overcrowding in different settings.

Otitis media with effusion is a common condition of childhood. The development of an information leaflet for parents of children with the condition, and its impact on clinical management, have not previously been examined.

Eighteen doctors and 38 parents assessed the content of an information leaflet on otitis media with effusion, by applying two rounds of the modified Delphi technique. A qualitative assessment of content items was also performed.

From the 23-item list used in the first assessment round, four items had a low doctor–parent agreement and seven were excluded. Differences were also noticed in comments on the value of such leaflets, with parents being more positive about the value of leaflet distribution.

During the consultation, doctors may not tell parents what they want to know, especially regarding daily care of their child. An information leaflet, developed using the Delphi technique, can help reduce this discrepancy and increase parents' satisfaction.
