Consensus definition of a radiologically healed fistula on magnetic resonance imaging in perianal Crohn’s disease: an international Delphi study

IntroductionPerianal fistulising Crohn’s disease (pfCD) is a distinct and debilitating phenotype seen in around one-third of patients with CD. Clinical trials in pfCD are increasingly using magnetic resonance imaging (MRI) criteria as a primary endpoint, but there is heterogeneity in the radiological definition of a healed perianal fistula that currently limits our ability to perform meaningful meta-analyses of studies. Our aim is to standardise outcomes through the generation of an international consensus definition of a radiologically healed fistula.Methods and analysisThis international Delphi consensus study employs a two-part strategy.The first is a systematic review to identify a longlist of variables used to define radiological healing in pfCD. MRI-based indices used to score fistula severity and healing will be assessed for their methodological quality using Consensus-based Standards for the selection of health Measurement Instruments (COSMIN). The systematic review protocol will be conducted using COSMIN methodology and reported using Preferred Reporting Items for Systematic Reviews and Meta-Analyses.The second part will be an online Delphi consensus, guided by the results of the systematic review. Radiologists, gastroenterologists and colorectal surgeons with expertise in the management of pfCD will be invited to take part in two to three rounds of online surveys. Once an a priori threshold of >80% agreement is reached on individual radiological components used to define ‘healing’ and ‘healed’, a final meeting of key stakeholders will be organised to generate a consensus definition of a healed fistula.Ethics and disseminationThe study has been deemed exempt from a formal Research Ethics Committee review as no patients will participate directly in the consensus process, given the technical nature of the research question. The study is registered with the local R&D department (Reference RD24/007). Publication of this study will help standardise radiological endpoint measurement in clinical trials of pfCD and improve the synthesis and meta-analysis of comparative studies.PROSPERO registration numberCRD42024504334.

IFSO Bariatric Endoscopy Committee Evidence-Based Review and Position Statement on Endoscopic Sleeve Gastroplasty for Obesity Management.

Obesity is a significant global health issue. Metabolic and bariatric surgery (MBS) is the gold standard in the treatment of obesity due to its proven effectiveness and safety in the short and long term. However, MBS is not suitable for all patients. Some individuals are at high surgical risk or refuse surgical treatment, while others do not meet the criteria for MBS despite having obesity-related comorbidities. This gap has driven the development of endoscopic solutions like endoscopic sleeve gastroplasty (ESG), which offers a less invasive alternative that preserves organ function and reduces risks. A recent IFSO International Delphi consensus study highlighted that multidisciplinary experts agree on the utility of ESG for managing obesity in patients with class I and II obesity and for those with class III obesity who do not wish to pursue or qualify for MBS. This IFSO Bariatric Endoscopy Committee position statement aims to augment these consensus statements by providing a comprehensive systematic review of the evidence and delivering an evidence-based position on the value of ESG within the spectrum of obesity management. A comprehensive systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and Cochrane guidelines. Systematic Review: The systematic review included 44 articles encompassing 15,714 patients receiving ESG. The studies varied from large case series to cohort studies and a randomized controlled trial (RCT). The mean baseline BMI was 37.56kg/m2. The review focused on weight loss outcomes and safety data. Time point Mean %EWL Mean %TBWL 6months 48.04 15.66 12months 53.09 17.56 18months 57.98 16.25 24months 46.57 15.2 36months 53.18 14.07 60months 45.3 15.9 These results demonstrate significant weight loss following ESG. The pooled serious adverse event (SAE) rate was 1.25%. This low rate of SAEs indicates that ESG is a relatively safe procedure. The quality of evidence from the included observational studies was assessed as very low, primarily due to the inherent limitations associated with observational study designs, such as potential biases and lack of randomization. In contrast, the quality of evidence from the single randomized controlled trial was rated as MODERATE, reflecting a more robust study design that provides a higher level of evidence despite some limitations. The IFSO Bariatric Endoscopy Committee, after conducting a comprehensive systematic review and meta-analysis, endorses endoscopic sleeve gastroplasty (ESG) as an effective and valuable treatment for obesity. ESG is particularly beneficial for patients with class I and II obesity, as well as for those with class III obesity who are not suitable candidates for metabolic bariatric surgery. ESG provides significant weight loss outcomes and demonstrates a favorable safety profile with a low rate of serious adverse events. Despite the limitations of the included observational studies, the randomized controlled trial included in the analysis reinforces the efficacy and safety of ESG and provides an evidence-based foundation for the position statement. Thus, the IFSO position statement supports and provides an evidence base for the role of ESG within the broader spectrum of obesity management.

Optimal child-led goal setting practices for school-aged children with a disability or delay: an international Delphi consensus study

Aim To achieve expert consensus on optimal child-led goal setting and evaluation practices for school-aged children (5 ≤ 17 years) who have a disability or delay. Method A three-round, eDelphi consensus design was used. In Round 1, expert allied health professionals identified factors important during child-led goal setting for: (i) planning, (ii) process steps and tools, and (iii) support strategies. Factors were collated into items for Rounds 2 and 3. Participants rated item agreement on a 7-point Likert scale. Consensus was determined as ≥75% of participants in agreement or disagreement. Results Sixty professionals from nine countries and six disciplines participated. Of 323 unique items generated, 159 (50%) reached consensus. Strong agreement was reached for goal setting and evaluation “process steps” and “support strategies” to engage children. It was strongly recommended that allied health professionals should tailor their processes to each child’s individual needs, provide ability-specific strategies and resources, and empower children to share their perspectives. Fewer items reached consensus for “planning” and “tools” to guide child-led goal setting. Interpretation Professional experts agree that children can be actively involved in goal setting and evaluation. Future research should focus on tools and technologies to support child-led goal setting for children with diverse abilities.

Development of a framework of the skills and attributes needed by mental health professionals to provide optimal clinical care to people experiencing complex psychosis: A Delphi consensus study.

Complex psychosis is associated with high social and economic costs. The key skills and attributes needed by mental health professionals to provide optimal clinical care to people experiencing complex psychosis have not previously been defined. A framework detailing these skills and attributes is needed to support the identification of training needs for those working with this population. A modified online Delphi method was used to reach consensus on the skills and attributes essential for mental health professionals to deliver optimal clinical care to people experiencing complex psychosis. Participants were international healthcare professionals and academic researchers who self-identified as experts in complex psychosis. Participants were asked to rate their level of agreement with each item on a five-point Likert-type scale and to provide comments. Qualitative feedback was used to modify existing, or create new, items for subsequent rounds. 64 responses were received across three Delphi rounds. 167 items reached consensus and were endorsed (132 in Round 1, 31 in Round 2 and 4 in Round 3). Median score range for endorsed items was 4.5/5, with 88.6% scoring 5/5. All 167 endorsed items were included in the framework, categorised into 14 overarching domains. Multiple skills and attributes were identified as being core components required in the delivery of optimal care by mental health professionals to people experiencing complex psychosis. The resulting framework provides a benchmark for training and skill development of mental health clinicians at both individual and team levels to optimise effective working with this high-needs population.

Establishing Outcome Parameters for Helicopter Emergency Medical Services Research in The Netherlands: Results of a Mixed-Methods Delphi Consensus Study

Objectives Physician staffed Helicopter Emergency Medical Services (P-HEMS) care in the Netherlands has transitioned from predominantly trauma management to handling a variety of medical conditions. Relevant outcome parameters for Dutch P-HEMS research have not been previously defined. National consensus was sought to identify relevant long term patient outcome parameters, process outcome parameters and performance outcome parameters for Dutch P-HEMS care. Methods This was a mixed methods Delphi consensus study. A list of potentially relevant outcome parameters was identified using a systematic literature review. These parameters were subsequently surveyed in a Delphi consensus study. Helicopter Emergency Medical Services physicians and relevant stakeholders were invited to participate in this Delphi survey, where they were allowed to suggest additional outcome parameters. Descriptive analysis was performed on all data sets. Results Forty-nine potential outcome parameters for Dutch P-HEMS care were surveyed. Of 71 invited participants, 53 (75%), 40 (56%), and 20 (28%) participated in the first, second, and third round of the Delphi study, respectively. Consensus was reached on 25 (51%) of 49 outcome parameters as being important. These consisted of seven long term patient related outcome parameters, four short term patient related outcome parameters, five process outcome parameters and nine performance outcome parameters. Conclusions In conclusion, this study identified 25 outcome parameters relevant for Dutch physician staffed HEMS care. These parameters should be considered when designing future studies and should be routinely collected for each dispatch if possible.

Defining a core outcome set for hypermobility spectrum disorders and hypermobile Ehlers-Danlos syndrome: A Delphi consensus study.

The reported prevalence of hypermobility spectrum disorders (HSD) and hypermobile Ehlers-Danlos Syndrome (hEDS) is unclear due to complex presentations and lack of awareness amongst professionals, contributing to diagnostic and management uncertainties. Standardising an outcome measure to assess symptoms most important to patients should help determine the impact of interventions. This Delphi study aims to reach a consensus with stakeholders on the core outcome set for children and adults with HSD/hEDS. A three-round modified Delphi consensus study with a follow-up consensus meeting was used. Stakeholder groups consisted of (1) individuals with HSD/hEDS; (2) family/friends/carers and (3) healthcare professionals. Participants could belong to more than one stakeholder group. They rated 74 symptoms using a 9-point Likert scale: 1 "not important to 9 "critically important". Symptoms achieving a consensus rating of ≥ 70.0% critical importance across all groups were included. In Round 1, 766 responses were received from 600 participants, reducing to 566 responses from 438 participants by Round 3, with 53 participating in the consensus meeting. Overall, 30 symptoms met the ≥ 70.0% critically important threshold to be included in the final core outcome set. These were categorised under the specialties of musculoskeletal and orthopaedics, social, pain, gynaecology and urology, negative affect, neurological, gastrointestinal and "other". This study is the first to identify by consensus the core outcome set to be measured for patients with HSD/hEDS. The importance of these outcomes was confirmed by individuals living with the condition, their family, friends, carers and relevant healthcare professionals. Trial registration: IRAS ID: 326,855; East Midlands - Leicester South REC (reference: 23/EM/0143); Protocol registered with the COMET Initiative. Key Points • There is a lack of standardised outcome measure for HSD/hEDS research studies due to the heterogeneity of symptom presentations. • Symptoms across musculoskeletal and orthopaedics, social, pain, gynaecology and urology, negative affect, neurological, gastrointestinal and "other" specialties were identified as the core outcome set defined as ≥ 70.0% critically important to measure for individuals with HSD/hEDS. • There were a significant number of symptoms, widely recognised in the literature to be comorbid to HSD/hEDS, that reached a critical importance threshold of 50.0-69.9%, restricting the core outcome set to only those that met 70% or above may be limiting.

Variables for reporting studies on extended - focused assessment with sonography for trauma (E-FAST): An international delphi consensus study

BackgroundThe Extended Focused Assessment with Sonography for Trauma (E-FAST) is a diagnostic ultrasound technique used in hospital and pre-hospital settings for patients with torso trauma. While E-FAST is common in emergency departments, its pre-hospital use is less routine. This study aims to establish a set of variables for designing studies on pre-hospital E-FAST through a Delphi consensus process involving international experts. MethodsA Delphi consensus process was utilized, involving four rounds of e-mail to the experts. The experts proposed variables for each category, assessed them using a 5-point Likert scale, and voted on whether they should be included in the final template. ResultsOut of 14 invited experts, 9 participated in the study. In total, the experts proposed 247 variables. After four rounds, a final list of 32 variables was approved by all experts. These variables related to the system, patient, process, training, imaging, outcome, and others. ConclusionsThis Delphi consensus study presents a list of 32 variables for future research studies concerning the use of E-FAST ultrasound in pre-hospital settings. The results of this study are significant as they provide a standardized set of variables that will facilitate the comparison of data obtained from various studies. This will ultimately contribute to the advancement of pre-hospital E-FAST research and practice.

Expert opinion on use of vagus nerve stimulation therapy in the management of pediatric epilepsy: a Delphi consensus study

Purpose: To provide consensus-based recommendations for use of vagus nerve stimulation (VNS) therapy in the management of pediatric epilepsy. Methods: Delphi methodology with two rounds of online survey was used to build consensus. A steering committee developed 43 statements related to pediatric epilepsy and the use of VNS therapy, which were evaluated by a panel of 12 neurologists/neurosurgeons with expertise in pediatric epilepsy, who graded their agreement with each statement on a scale of 1 (“I do not agree at all”) to 5 (“I strongly agree”). For each statement, consensus was established if ≥70% of the agreement scores were 4 or 5 and <30% were 1 or 2 in the final survey. Results: Twenty-four statements regarding the need for seizure reduction in pediatric epilepsy, the recommended treatment algorithm, the benefits and safety of VNS therapy, management of side effects of VNS therapy, patient selection for VNS therapy, and the use, dosing, and titration of VNS therapy achieved consensus. VNS and other neuromodulation therapies should be considered for pediatric patients with drug-resistant epilepsy who are not candidates for resective surgery, or who do not remain seizure free after resective surgery. When VNS therapy is initiated, the target dose range should be achieved via the fastest and safest titration schedule for each patient. Scheduled programming can be helpful in dose titration. Conclusion: The expert consensus statements represent the panelists’ collective opinion on the best practice use of VNS therapy to optimize outcomes in the management of pediatric epilepsy.

Parenting strategies to support adolescent mental health during a pandemic: A Delphi consensus study

BackgroundThe COVID-19 pandemic has had ongoing detrimental effects on mental health, especially for young people. Parents can play a crucial role in the prevention of youth depression and anxiety disorders. While parenting guidelines for reducing the risk of adolescent depression and anxiety have been developed, they needed to be adapted for the unique challenges brought by a pandemic. MethodThis study employed the Delphi methodology to establish expert consensus on parenting strategies that are important for preventing adolescent depression or anxiety disorders during a pandemic. Through a literature search and panel recommendations, we identified 304 parenting recommendations. These were presented to an international panel of 35 experts in parenting and youth mental health, who rated the importance of these recommendations in preventing adolescent depression and anxiety over three survey rounds. ResultsThere were 167 parenting strategies endorsed as important or essential in reducing adolescents' risk of developing depression or anxiety disorders during a pandemic by ≥90% of the panel. These strategies were written into a set of specific and actionable guidelines for parenting through the pandemic, and made freely available online for parents. ConclusionsThis study adapted an original set of parenting guidelines for the COVID-19 pandemic, supported by research evidence and/or international experts, which can be promoted in Western English-speaking communities to help parents protect their adolescents from depression and anxiety disorders during pandemic and post-pandemic times.

Competencies required by sonographers teaching ultrasound interprofessionally: a Delphi consensus study

BackgroundClinicians from multiple professional backgrounds are increasingly using point-of-care ultrasound in clinical practice. Performing ultrasound is a complex skill, and training is required to ensure competency and patient safety. There is a lack of skilled trainers within health professions to meet this increasing educational demand. The role of sonographers in educating other health professionals in point-of-care ultrasound has not yet been well defined. Sonographers can provide ultrasound education interprofessionally, if equipped with appropriate clinical knowledge and educational skills.MethodsA Delphi consensus study was conducted to define the knowledge, skills and attributes required of sonographers teaching point-of-care ultrasound to other health professionals in Australia and New Zealand. Health professionals with subject matter expertise in the leadership, facilitation, and delivery of ultrasound education by sonographers were invited to participate.ResultsThere were 72 expert participants in survey round one, and 49 in round two. Participants included physicians, sonographers, and other health professionals. Consensus was reached on 31 competency items for sonographers teaching ultrasound interprofessionally, with agreement of greater than 94% reached by participants.ConclusionsThis consensus study has defined the knowledge, skills and attitudes required for sonographer competence in point-of-care ultrasound education. This is an important step to developing a training pathway for sonographers engaging in this emerging area.

A Reporting Checklist for Discrete Choice Experiments in Health: The DIRECT Checklist.

Reporting standards of discrete choice experiments (DCEs) in health have not kept pace with the growth of this method, with multiple reviews calling for better reporting to improve transparency, assessment of validity and translation. A key missing piece has been the absence of a reporting checklist that details minimum standards of what should be reported, as exists for many other methods used in health economics. This paper reports the development of a reporting checklist for DCEs in health, which involved a scoping review to identify potential items and a Delphi consensus study among 45 DCE experts internationally to select items and guide the wording and structure of the checklist. The Delphi study included a best-worst scaling study for prioritisation. The final checklist is presented along with guidance on how to apply it. This checklist can be used by authors to ensure that sufficient detail of a DCE's methods are reported, providing reviewers and readers with the information they need to assess the quality of the study for themselves. Embedding this reporting checklist into standard practice for health DCEs offers an opportunity to improve consistency of reporting standards, thereby enabling transparency of review and facilitating comparison of studies and their translation into policy and practice.

A Framework for Measuring Neighborhood Walkability for Older Adults-A Delphi Consensus Study.

While mobility in older age is of crucial importance for health and well-being, it is worth noting that currently, there is no German language framework for measuring walkability for older adults that also considers the functional status of a person. Therefore, we combined the results of an expert workshop, a literature review, and a Delphi consensus survey. Through this, we identified and rated indicators relevant for walkability for older adults, additionally focusing on their functional status. The expert workshop and the review led to an extensive list of potential indicators, which we hope will be useful in future research. Those indicators were then adapted and rated in a three-stage Delphi expert survey. A fourth additional Delphi round was conducted to assess the relevance of each indicator for the different frailty levels, namely "robust," "pre-frail," and "frail." Between 20 and 28 experts participated in each round of the Delphi survey. The Delphi process resulted in a list of 72 indicators deemed relevant for walkability in older age groups, grouped into three main categories: "Built environment and transport infrastructure," "Accessibility and meeting places," and "Attractiveness and sense of security." For 35 of those indicators, it was suggested that functional status should be additionally considered. This framework represents a significant step forward in comprehensively covering indicators for subjective and objective walkability in older age, while also incorporating aspects of functioning relevant to older adults. It would be beneficial to test and apply the indicator set in a community setting.

590. RESOLUTION OF SYMPTOMS AFTER OESOPHAGO-GASTRIC CANCER RESECTION (RESTORED)–STANDARDISING GASTROINTESTINAL SYMPTOMS AND CONDITIONS AFTER SURGERY: A MULTI-DISCIPLINARY EXPERT DELPHI STUDY

Abstract Background Oesophago-gastric cancer surgery negatively affects quality of life with a high post-operative symptom burden. Several conditions that may be diagnosed and treated after surgery are recognised. However, consensus regarding their definition and management is lacking. We aimed to develop consensus regarding the definition, investigation and management of the common symptoms and conditions, and triggers to consider disease recurrence, as a foundation for improving management and quality of life in these patients. Design Modified 2-round Delphi consensus study of a multidisciplinary expert panel. Results 86/127(67.7%) and 77/100(77.0%) responses were received in rounds 1 and 2. Consensus was achieved in defining 26 symptoms. For 10 conditions (anastomotic stricture, acid reflux, non-acid reflux, biliary gastritis, delayed gastric emptying, dumping syndrome, exocrine pancreatic insufficiency, bile acid diarrhoea, small intestinal bacterial overgrowth and carbohydrate malabsorption), definitions, diagnostic criteria, first and second-line investigation and first-line treatments were agreed. Consensus was not reached for third line investigation of some conditions, nor for second, third or fourth-line treatments for others. 12 of 14(85.7%) symptoms were agreed as triggers to consider cancer recurrence, during the early (&amp;lt; 1 year) and late (&amp;gt; 1 year) post-operative periods. Conclusion Expert consensus regarding symptoms, conditions and triggers to consider investigation for recurrence after oesophago-gastric cancer surgery was achieved. This will allow standardisation and timely diagnosis and treatment of post-operative conditions, reducing variation in care. It will facilitate comparative, prospective research to establish the incidence and response to treatment of these conditions, helping develop robust evidence to optimise patients’ quality of life.

Codesign of a Quality Improvement Tool for Adults With Prolonged Critical Illness: A Modified Delphi Consensus Study.

Increasing numbers of patients experience a prolonged stay in intensive care. Yet existing quality improvement (QI) tools used to improve safety and standardize care are not designed for their specific needs. This may result in missed opportunities for care and contribute to worse outcomes. Following an experience-based codesign process, our objective was to build consensus on the most important actionable processes of care for inclusion in a QI tool for adults with prolonged critical illness. Items were identified from a previous systematic review and interviews with former patients, their care partners, and clinicians. Two rounds of an online modified Delphi survey were undertaken, and participants were asked to rate each item from 1 to 9 in terms of importance for effective care; where 1-3 was not important, 4-6 was important but not critical, and 7-9 was critically important for inclusion in the QI tool. A final consensus meeting was then moderated by an independent facilitator to further discuss and prioritize items. Carried out in the United Kingdom. Former patients who experienced a stay of over 7 days in intensive care, their family members and ICU staff. None. We recruited 116 participants: 63 healthcare professionals (54%), 45 patients (39%), and eight relatives (7%), to Delphi round 1, and retained 91 (78%) in round 2. Of the 39 items initially identified, 32 were voted "critically important" for inclusion in the QI tool by more than 70% of Delphi participants. These were prioritized further in a consensus meeting with 15 ICU clinicians, four former patients and one family member, and the final QI tool contains 25 items, including promoting patient and family involvement in decisions, providing continuity of care, and structured ventilator weaning and rehabilitation. Using experience-based codesign and rigorous consensus-building methods we identified important content for a QI tool for adults with prolonged critical illness. Work is underway to understand tool acceptability and optimum implementation strategies.

Top DEI Topics to Incorporate Into Dermatology Residency Training: An Electronic Delphi Consensus Study.

Current dermatology residency education may be deficient in curricular topics and training related to diversity, equity, and inclusion (DEI). Integrating more DEI topics within residency curricula may improve clinical care delivered to diverse populations and improve cultural humility among trainees. The objective of this electronic Delphi (e-Delphi) study was to reach a consensus on the most important DEI topics for inclusion in dermatology residency program curricula nationwide. Sixty-one DEI-related topics were proposed by an expert panel consisting of dermatologists from the Association of Professors of Dermatology DEI subcommittee and the American Academy of Dermatology Diversity Task Force. Two rounds of anonymous electronic surveys based on a 5-point Likert scale were administered using a modified e-Delphi design. Voluntary participants including residents and academic dermatologists were self-selected after an email was sent to the Association of Professors of Dermatology listserve.

Adaptive Deep Brain Stimulation in Parkinson's Disease: A Delphi Consensus Study.

If history teaches, as cardiac pacing moved from fixed-rate to on-demand delivery in in 80s of the last century, there are high probabilities that closed-loop and adaptive approaches will become, in the next decade, the natural evolution of conventional Deep Brain Stimulation (cDBS). However, while devices for aDBS are already available for clinical use, few data on their clinical application and technological limitations are available so far. In such scenario, gathering the opinion and expertise of leading investigators worldwide would boost and guide practice and research, thus grounding the clinical development of aDBS. We identified clinical and academically experienced DBS clinicians (n=21) to discuss the challenges related to aDBS. A 5-point Likert scale questionnaire along with a Delphi method was employed. 42 questions were submitted to the panel, half of them being related to technical aspects while the other half to clinical aspects of aDBS. Experts agreed that aDBS will become clinical practice in 10 years. In the present scenario, although the panel agreed that aDBS applications require skilled clinicians and that algorithms need to be further optimized to manage complex PD symptoms, consensus was reached on aDBS safety and its ability to provide a faster and more stable treatment response than cDBS, also for tremor-dominant Parkinson's disease patients and for those with motor fluctuations and dyskinesias. Despite the need of further research, the panel concluded that aDBS is safe, promises to be maximally effective in PD patients with motor fluctuation and dyskinesias and therefore will enter into the clinical practice in the next years, with further research focused on algorithms and markers for complex symptoms.

Prehospital guidelines on in-water traumatic spinal injuries for lifeguards and prehospital emergency medical services: an international Delphi consensus study

BackgroundTrauma guidelines on spinal motion restriction (SMR) have changed drastically in recent years. An international group of experts explored whether consensus could be reached and if guidelines on SMR performed by trained lifeguards and prehospital EMS following in-water traumatic spinal cord injury (TSCI) should also be changed.MethodsAn international three-round Delphi process was conducted from October 2022 to November 2023. In Delphi round one, brainstorming resulted in an exhaustive list of recommendations for handling patients with suspected in-water TSCI. The list was also used to construct a preliminary flowchart for in-water SMR. In Delphi round two, three levels of agreement for each recommendation and the flowchart were established. Recommendations with strong consensus (≥ 85% agreement) underwent minor revisions and entered round three; recommendations with moderate consensus (75–85% agreement) underwent major revisions in two consecutive phases; and recommendations with weak consensus (< 75% agreement) were excluded. In Delphi round 3, the level of consensus for each of the final recommendations and each of the routes in the flowchart was tested using the same procedure as in Delphi round 2.ResultsTwenty-four experts participated in Delphi round one. The response rates for Delphi rounds two and three were 92% and 88%, respectively. The study resulted in 25 recommendations and one flowchart with four flowchart paths; 24 recommendations received strong consensus (≥ 85%), and one recommendation received moderate consensus (81%). Each of the four paths in the flowchart received strong consensus (90–95%). The integral flowchart received strong consensus (93%).ConclusionsThis study produced expert consensus on 25 recommendations and a flowchart on handling patients with suspected in-water TSCI by trained lifeguards and prehospital EMS. These results provide clear and simple guidelines on SMR, which can standardise training and guidelines on SMR performed by trained lifeguards or prehospital EMS.
