A collaborative endeavour to integrate leadership and person-centred ethics: a focus group study on experiences from developing and realising an educational programme to support the transition towards person-centred care.

BACKGROUND: Ensuring the transition towards person-centred care is a growing focus in health and social care systems globally. Presented as an ethical framework for health and social care professionals, such a transition requires strong leadership and organisational changes. However, there is limited guidance available on how to assist health and social care leaders in promoting person-centred practices. In response to this, the Swedish Association of Health Professionals and the University of Gothenburg Centre for Person-Centred Care collaborated to develop an educational programme on person-centred leadership targeting health and social care leaders to support the transition towards person-centred care in Sweden. The aim with this study was to explore programme management members' experiences from the development and realisation of the programme. METHODS: Focus group discussions were conducted, involving 12 members of the programme management team. Data from the discussions were analysed using a structured approach with emphasis the collaborative generation of knowledge through participant interaction. RESULTS: The analysis visualises the preparations and actions involved in programme development and realisation as a collaborative endeavour, aimed at integrating leadership and person-centred ethics in a joint learning process. Participants described the programme as an ongoing exploration, extending beyond its formal duration. Leadership was thoughtfully interwoven with person-centred ethics throughout the programme, encompassing both the pedagogical approach and programme curriculum, to provide leaders with tangible tools for their daily use. CONCLUSIONS: According to our analysis, we conclude that a person-centred approach to both development and realisation of educational initiatives to support person-centred leadership is essential for programme enhancement and daily implementation of person-centred leadership. Our main message is that educational initiatives on the application of person-centred ethics is an ongoing and collaborative process, characterised by an exchange of ideas and collective efforts.

Care in emergencies and disasters: Can it be person-centered?

OBJECTIVES: While person-/patient-centered care aims to influence policymakers' rules and regulations to improve the care of individuals worldwide, exploration of the concept in the context of disaster and public health emergencies as an alternative ethical approach is lacking. This study aims to provide a nuanced understanding of the advantages and challenges of diverse ethical approaches in emergencies, to improve patient care. METHODS: A survey, created after several rounds of Delphi methodology, with 22 statements, was applied to 39 participants from nine different countries. The questionnaire's results, including participants' comments, were analyzed. RESULTS: The results show that practitioners chose to use a combination of diverse ethical approaches in managing victims of disasters and public health emergencies. CONCLUSION: The selection of an approach is context- and situation-dependent and seems to primarily respond to the nature of underlying etiology, creating a possibility to use diverse approaches to offer individualized care on a later occasion and when a flexible surge capacity is available. PRACTICE IMPLICATIONS: The outcomes of this study will enhance the future ethical discussion in person/patient-centered care during situations with limited resources and help to develop necessary ethical and educational guidelines.

The implication of a translational triage tool in mass casualty incidents: part three: a multinational study, using validated patient cards.

BACKGROUND: Mass casualty incidents (MCI) pose significant challenges to existing resources, entailing multiagency collaboration. Triage is a critical component in the management of MCIs, but the lack of a universally accepted triage system can hinder collaboration and lead to preventable loss of life. This multinational study uses validated patient cards (cases) based on real MCIs to evaluate the feasibility and effectiveness of a novel Translational Triage Tool (TTT) in primary triage assessment of mass casualty victims. METHODS: Using established triage systems versus TTT, 163 participants (1575 times) triaged five patient cases. The outcomes were statistically compared. RESULTS: TTT demonstrated similar sensitivity to the Sieve primary triage method and higher sensitivity than the START primary triage system. However, the TTT algorithm had a lower specificity compared to Sieve and higher over-triage rates. Nevertheless, the TTT algorithm demonstrated several advantages due to its straightforward design, such as rapid assessment, without the need for additional instrumental interventions, enabling the engagement of non-medical personnel. CONCLUSIONS: The TTT algorithm is a promising and feasible primary triage tool for MCIs. The high number of over-triages potentially impacts resource allocation, but the absence of under-triages eliminates preventable deaths and enables the use of other personal resources. Further research involving larger participant samples, time efficiency assessments, and real-world scenarios is needed to fully assess the TTT algorithm's practicality and effectiveness in diverse multiagency and multinational contexts.

Fast track to stroke unit for patients not eligible for acute intervention, a case-control register study on 1066 patients.

Stroke patients not eligible for acute intervention often have low priority and may spend long time at the emergency department (ED) waiting for admission. The aim of this retrospective case-control register study was to evaluate outcomes for such "low priority" stroke patients who were transported via Fast Track directly to the stroke unit, according to pre-specified criteria by emergency medical service (EMS). The outcomes of Fast Track patients, transported directly to stroke unit (cases) were compared with the outcomes of patients who fulfilled these critera for Fast Track, but instead were transported to the ED (controls). In all, 557 cases and 509 controls were identified. The latter spent a mean time of 237 min in the ED before admission. The 90-day mortality rate was 12.9% for cases and 14.7% for controls (n.s.). None of the secondary outcome events differed significantly between the groups: 28-day mortality rate; death rate during hospitalisation; proportion of pneumonias, falls or pressure ulcers; or health-related outcomes according to the EQ-5D-5L questionnaire. These findings indicates that the Fast Track to the stroke unit by an EMS is safe for selected stroke patients and could avoid non-valuable time in the ED.

The impact of the three-level collaboration exercise on collaboration and leadership during scenario-based hospital evacuation exercises using flexible surge capacity concept: a mixed method cross-sectional study.

BACKGROUND: Hospitals play a crucial role in responding to disasters and public health emergencies. However, they are also vulnerable to threats such as fire or flooding and can fail to respond or evacuate adequately due to unpreparedness and lack of evacuation measures. The United Nations Office for Disaster Risk Reduction has emphasised the importance of partnerships and capacity building in disaster response. One effective way to improve and develop disaster response is through exercises that focus on collaboration and leadership. This study aimed to examine the effectiveness of using the 3-level collaboration (3LC) exercise in developing collaboration and leadership in districts in Thailand, using the concept of flexible surge capacity (FSC) and its collaborative tool during a hospital evacuation simulation. METHODS: A mixed-method cross-sectional study was conducted with 40 participants recruited from disaster-response organisations and communities. The data from several scenario-based simulations were collected according to the collaborative elements (Command and control, Safety, Communication, Assessment, Triage, Treatment, Transport), in the disaster response education, "Major Incident Medical Management and Support" using self-evaluation survey pre- and post-exercises, and direct observation. RESULTS: The 3LC exercise effectively facilitated participants to gain a mutual understanding of collaboration, leadership, and individual and organisational flexibility. The exercise also identified gaps in communication and the utilisation of available resources. Additionally, the importance of early community engagement was highlighted to build up a flexible surge capacity during hospital evacuation preparedness. CONCLUSIONS: the 3LC exercise is valuable for improving leadership skills and multiagency collaboration by incorporating the collaborative factors of Flexible Surge Capacity concept in hospital evacuation preparedness.

Diffusion of person-centred care within 27 European countries - interviews with managers, officials, and researchers at the micro, meso, and macro levels.

PURPOSE: This study aimed to describe facilitators and barriers in terms of regulation and financing of healthcare due to the implementation and use of person-centred care (PCC). DESIGN/METHODOLOGY/APPROACH: A qualitative design was adopted, using interviews at three different levels: micro = hospital ward, meso = hospital management, and macro = national board/research. Inclusion criteria were staff working in healthcare as first line managers, hospital managers, and officials/researchers on national healthcare systems, such as Bismarck, Beveridge, and mixed/out-of-pocket models, to obtain a European perspective. FINDINGS: Countries, such as Great Britain and Scandinavia (Beveridge tax-based health systems), were inclined to implement and use person-centred care. The relative freedom of a market (Bismarck/mixed models) did not seem to nurture demand for PCC. In countries with an autocratic culture, that is, a high-power distance, such as Mediterranean countries, PCC was regarded as foreign and not applicable. Another reason for difficulties with PCC was the tendency for corruption to hinder equity and promote inertia in the healthcare system. RESEARCH LIMITATIONS/IMPLICATIONS: The sample of two to three participants divided into the micro, meso, and macro level for each included country was problematic to find due to contacts at national level, a bureaucratic way of working. Some information got caught in the system, and why data collection was inefficient and ran out of time. Therefore, a variation in participants at different levels (micro, meso, and macro) in different countries occurred. In addition, only 27 out of the 49 European countries were included, therefore, conclusions regarding healthcare system are limited. PRACTICAL IMPLICATIONS: Support at the managerial level, together with patient rights supported by European countries' laws, facilitated the diffusion of PCC. ORIGINALITY/VALUE: Fragmented health systems divided by separate policy documents or managerial roadmaps hindered local or regional policies and made it difficult to implement innovation as PCC. Therefore, support at the managerial level, together with patient rights supported by European countries' laws, facilitated the diffusion of PCC.

Developing a translational triage research tool: part two-evaluating the tool through a Delphi study among experts.

BACKGROUND: There are different prehospital triage systems, but no consensus on what constitutes the optimal choice. This heterogeneity constitutes a threat in a mass casualty incident in which triage is used during multiagency collaboration to prioritize casualties according to the injuries' severity. A previous study has confirmed the feasibility of using a Translational Triage Tool consisting of several steps which translate primary prehospital triage systems into one. This study aims to evaluate and verify the proposed algorithm using a panel of experts who in their careers have demonstrated proficiency in triage management through research, experience, education, and practice. METHOD: Several statements were obtained from earlier reports and were presented to the expert panel in two rounds of a Delphi study. RESULTS: There was a consensus in all provided statements, and for the first time, the panel of experts also proposed the manageable number of critical victims per healthcare provider appropriate for proper triage management. CONCLUSION: The feasibility of the proposed algorithm was confirmed by experts with some minor modifications. The utility of the translational triage tool needs to be evaluated using authentic patient cards used in simulation exercises before being used in actual triage scenarios.

Coexisting service-related factors preceding suicide: a network analysis.

OBJECTIVES: The overall objective was to analyse service-related factors involved in the complex processes that precede suicide in order to identify potential targets for intervention. DESIGN AND SETTING: Explorative network analysis study of post-suicide root cause analysis data from Swedish primary and secondary healthcare. PARTICIPANTS: 217 suicide cases reported to the Swedish national root cause analysis database between 2012 and 2017. PRIMARY AND SECONDARY OUTCOME MEASURES: A total of 961 reported incidents were included. Demographic data and frequencies of reported deficiencies were registered. Topology, centrality indices and communities were explored for three networks. All networks have been tested for robustness and accuracy. RESULTS: Lack of follow-up, evaluations and insufficient documentation issues emerged as central in the network of major themes, as did the contributing factors representing organisational problems, failing procedures and miscommunication. When analysing the subthemes of deficiencies more closely, disrupted treatments and staffing issues emerged as prominent features. The network covering the subthemes of contributing factors also highlighted discontinuity, fragile work structures, inadequate routines, and lack of resources and relevant competence as potential triggers. However, as the correlation stability coefficients for this network were low, the results need further investigation. Four communities were detected covering nodes for follow-up, evaluation, cooperation, and procedures; communication, documentation and organisation; assessments of suicide risk and psychiatric status; and staffing, missed appointments and declined treatment. CONCLUSION: The results of this study suggest that healthcare providers may improve patient safety in suicide preventive pathways by taking active measures to provide regular follow-ups to patients with elevated suicide risk. In some cases, declined or cancelled appointments could be a warning sign. Tentative results show organisational instability, in terms of work structure, resources and staffing, as a potential target for intervention, although this must be more extensively explored in the future.

A comparison of three organisational levels in one health care region in Sweden implementing person-centred care: coupled, decoupled or recoupled in a complex organisation.

BACKGROUND: Establishing more substantial patient involvement in the health care has become fundamental to Western health care services. Person-centred care (PCC) has been developed as a way of working that involve the patients and family members. However, the implementation of PCC in clinical practice has proven to be challenging. The aim of this study was to explore the congruence of managers' perceptions and understanding of various aspects of PCC across three organisational levels in one health care region in Sweden in terms of coupling, decoupling and recoupling. METHODS: A policy on increased patient participation in health care was adopted in one health care region in Sweden. This policy was embodied in the form of PCC and a support strategy for the implementation was put in place. Participants representing three organisational levels (senders: politicians, n = 3; messengers: senior management, n = 7; and receivers: middle- and frontline managers, n = 13) were interviewed and documents collected. A deductive qualitative content analysis was performed and findings from the three organisational levels compared. RESULTS: Descriptions of PCC at all the three organisational levels included health care provided in partnership between provider and patient. However, messengers and receivers also included aspects of how work was organised as part of the concept. Representatives at all levels expected high-quality care while reducing health care costs as an outcome, however, messengers and receivers also anticipated improvements in the work environment and reduced staff turnover. Strategies to support implementation included continuation and enhancement of existing routines that were considered person-centred and development of new ones. A need to make PCC less 'fuzzy' and ambiguous and instead communicate a more tangible care process was described. Representatives among messengers and receivers also suggested that no actions were needed because the practice was already considered person-centred. CONCLUSION: The findings indicated that congruence between organisational levels existed in some aspects, suggesting coupling between policy and practice. However, also incongruences were identified that might be due to the fuzziness of definitions and the application of PCC in practice, and the difficulty in assessing the level of patient-centredness in clinical practice.

Actions taken affecting lead time in the care pathway for low-priority patients with a suspected stroke: A critical incident study.

BACKGROUND: The time delay from alerted ambulance to arrival at the stroke unit is crucial for patients suffering a suspected stroke. This is a recognized problem why additional explorative knowledge regarding actions taken are needed. AIM: To explore actions taken by nurses that affect lead times in the care pathway from the alerted ambulance to the stroke unit, for low-priority patients suffering a suspected stroke. METHOD: The design of the study was explorative and descriptive and used a qualitative approach based on Critical Incident Technique (CIT). Twenty-two nurses involved in the stroke care pathway at an university hospital in western Sweden were interviewed about their actions that affected the lead time. RESULTS: Actions undertaken affected lead time in the stroke care pathway for low-priority patients related to "promoting the care chain process" and "taking control of the situation". CONCLUSIONS: The staff within all parts of the care pathway affected the lead time, individually as well as via interaction between departments. This calls for the need of further collaboration and consensus concerning how to facilitate a smooth care pathway.

Does the Prosperity of a Country Play a Role in COVID-19 Outcomes?

OBJECTIVE: This study aims to clarify the association between prosperity and the coronavirus disease (COVID-19) outcomes and its impact on the future management of pandemics. METHODS: This is an observational study using information from 2 online registries. The numbers of infected individuals and deaths and the prosperity rank of each country were obtained from worldometer.info and the Legatum Institute's Prosperity Index, respectively. RESULTS: There is a combination of countries with high and low prosperity on the list of COVID-19-infected countries. The risk of the virus pandemic seems to be more extensive in countries with high prosperity. A Spearman's rho test confirmed a significant correlation between prosperity, the number of COVID-19 cases, and the number of deaths at the 99% level. CONCLUSION: New emerging pandemics affect all nations. In order to increase the likelihood of successfully managing future events, it is important to consider preexisting health security, valid population-based management approaches, medical decision-making, communication, continuous assessment, triage, treatment, early and complete physical distancing strategies, and logistics. These elements cannot be taught on-site and on occasion. There is a need for innovative and regular educational activities for all stakeholders committed to safeguarding our future defense systems concerning diagnostic, protection, treatment, and rehabilitation in pandemics, as well as other emergencies.

Current Perspectives and Concerns Facing Hospital Evacuation: The Results of a Pilot Study and Literature Review.

OBJECTIVE: To analyze the evacuation preparedness of hospitals within the European Union (EU). METHOD: This study consisted of 2 steps. In the first step, a systematic review of the subject matter, according to the PRISMA flow diagram, was performed. Using Scopus (Elsevier, Amsterdam, Netherlands), PubMed (National Library of Medicine, Bethesda, MD), and Gothenburg University´s search engine, 11 questions were extracted from the review and were sent to representatives from 15 European Union (EU)- and non-EU countries. RESULTS: The findings indicate that there is neither a full preparedness nor a standard guideline for evacuation within the EU or other non-EU countries in this study. A major shortcoming revealed by this study is the lack of awareness of the untoward consequences of medical decision-making during an evacuation. Some countries did not respond to the questions due to the lack of relevant guidelines, instructions, or time. CONCLUSION: Hospitals are exposed to internal and external incidents and require an adequate evacuation plan. Despite many publications, reports, and conclusions on successful and unsuccessful evacuation, there is still no common guide for evacuation, and many hospitals lack the proper preparedness. There is a need for a multinational collaboration, specifically within the EU, to establish such an evacuation planning or guideline to be used mutually within the union and the international community.

Adoption of the concept of person-centred care into discourse in Europe: a systematic literature review.

PURPOSE: This study aims to describe how person-centred care, as a concept, has been adopted into discourse in 23 European countries in relation to their healthcare systems (Beveridge, Bismarck, out of pocket). DESIGN/METHODOLOGY/APPROACH: A literature review inspired by the SPICE model, using both scientific studies (CINHAL, Medline, Scopus) and grey literature (Google), was conducted. A total of 1,194 documents from CINHAL (n = 139), Medline (n = 245), Scopus (n = 493) and Google (n = 317) were analysed for content and scope of person-centred care in each country. Countries were grouped based on healthcare systems. FINDINGS: Results from descriptive statistics (percentage, range) revealed that person-centred care was most common in the United Kingdom (n = 481, 40.3%), Sweden (n = 231, 19.3%), the Netherlands (n = 80, 6.7%), Northern Ireland (n = 79, 6.6%) and Norway (n = 61, 5.1%) compared with Poland (0.6%), Hungary (0.5%), Greece (0.4%), Latvia (0.4%) and Serbia (0%). Based on healthcare systems, seven out of ten countries with the Beveridge model used person-centred care backed by scientific literature (n = 999), as opposed to the Bismarck model, which was mostly supported by grey literature (n = 190). PRACTICAL IMPLICATIONS: Adoption of the concept of person-centred care into discourse requires a systematic approach at the national (politicians), regional (guidelines) and local (specific healthcare settings) levels visualised by decision-making to establish a well-integrated phenomenon in Europe. SOCIAL IMPLICATIONS: Evidence-based knowledge as well as national regulations regarding person-centred care are important tools to motivate the adoption of person-centred care in clinical practice. This could be expressed by decision-making at the macro (law, mission) level, which guides the meso (policies) and micro (routines) levels to adopt the scope and content of person-centred care in clinical practice. However, healthcare systems (Beveridge, Bismarck and out-of-pocket) have different structures and missions owing to ethical approaches. The quality of healthcare supported by evidence-based knowledge enables the establishment of a well-integrated phenomenon in European healthcare. ORIGINALITY/VALUE: Our findings clarify those countries using the Beveridge healthcare model rank higher on accepting/adopting the concept of person-centered care in discourse. To adopt the concept of person-centred care in discourse requires a systematic approach at all levels in the organisation-from the national (politicians) and regional (guideline) to the local (specific healthcare settings) levels of healthcare.

The Feasibility of Implementing the Flexible Surge Capacity Concept in Bangkok: Willing Participants and Educational Gaps.

The management of emergencies consists of a chain of actions with the support of staff, stuff, structure, and system, i.e., surge capacity. However, whenever the needs exceed the present resources, there should be flexibility in the system to employ other resources within communities, i.e., flexible surge capacity (FSC). This study aimed to investigate the possibility of creating alternative care facilities (ACFs) to relieve hospitals in Bangkok, Thailand. Using a Swedish questionnaire, quantitative data were compiled from facilities of interest and were completed with qualitative data obtained from interviews with key informants. Increasing interest to take part in a FSC system was identified among those interviewed. All medical facilities indicated an interest in offering minor treatments, while a select few expressed interest in offering psychosocial support or patient stabilization before transport to major hospitals and minor operations. The non-medical facilities interviewed proposed to serve food and provide spaces for the housing of victims. The lack of knowledge and scarcity of medical instruments and materials were some of the barriers to implementing the FSC response system. Despite some shortcomings, FSC seems to be applicable in Thailand. There is a need for educational initiatives, as well as a financial contingency to grant the sustainability of FSC.

A translational triage research development tool: standardizing prehospital triage decision-making systems in mass casualty incidents.

BACKGROUND: There is no global consensus on the use of prehospital triage system in mass casualty incidents. The purpose of this study was to evaluate the most commonly used pre-existing prehospital triage systems for the possibility of creating one universal translational triage tool. METHODS: The Rapid Evidence Review consisted of (1) a systematic literature review (2) merging and content analysis of the studies focusing on similarities and differences between systems and (3) development of a universal system. RESULTS: There were 17 triage systems described in 31 eligible articles out of 797 identified initially. Seven of the systems met the predesignated criteria and were selected for further analysis. The criteria from the final seven systems were compiled, translated and counted for in means of 1/7's. As a product, a universal system was created of the majority criteria. CONCLUSIONS: This study does not create a new triage system itself but rather identifies the possibility to convert various prehospital triage systems into one by using a triage translational tool. Future research should examine the tool and its different decision-making steps either by using simulations or by experts' evaluation to ensure its feasibility in terms of speed, continuity, simplicity, sensitivity and specificity, before final evaluation at prehospital level.

Experienced critical incidents affecting lead-times in the stroke care chain for low-priority patients - A qualitative study with critical incident technique.

BACKGROUND: The time elapsing from the alarm being raised to arrival at the stroke unit is crucial for patients suffering a conceivable stroke. More knowledge is needed about critical incidents-both favourable and unfavourable-affecting the lead time in the care chain. AIM: To explore favourable and unfavourable critical incidents (CIs), affecting lead times in the care chain from the alerted ambulance to the stroke unit, as experienced by nurses, for low-priority patients suffering a conceivable acute stroke. METHOD: The study had an explorative descriptive design using a qualitative approach of Flanagan's Critical Incident Technique (CIT). Twenty-two nurses involved in the stroke care chain at a hospital in western Sweden were interviewed about their experiences regarding CIs influencing the lead time for low-priority patients. RESULTS: There were 363 CIs identified related to human interactions and organizational structures. The types of CIs varied depending on where in the care chain they were experienced. Both favourable and unfavourable factors had an impact on the length of the lead time from alerted ambulance to stroke unit for lowpriority patients. Furthermore, CIs occurring both early and later in the care chain affected the whole process. CONCLUSIONS: There is a need for greater understanding within each interrelated department in the care chain about how CIs at one part of the care chain have an impact on another.

Importance of Immediate Electronic-Based Feedback to Enhance Feedback for First-Time CPR Trainees.

Sudden cardiac arrest is one of the leading causes of death globally. The recommended clinical management in out-of-hospital cardiac arrest cases is the immediate initiation of high-quality cardiopulmonary resuscitation (CPR). Training mannequins should be combined with technology that provides students with detailed immediate feedback on the quality of CPR performance. This study aimed to verify the impacts of the type of feedback (basic or detailed) the responders receive from the device while learning CPR and how it influences the quality of their performance and the motivation to improve their skills. The study was conducted at the Medical University of Lublin among 694 multi-professional health students during first aid classes on basic life support (BLS). The students first practiced on an adult mannequin with a basic control panel; afterward, the same mannequin was connected to a laptop, ensuring a detailed record of the performed activities through a projector. Next, the participants expressed their subjective opinion on how the feedback provided during the classes, basic vs. detailed, motivated them to improve the quality of their CPR performance. Additionally, during the classes, the instructor conducted an extended observation of students' work and behavior. In the students' opinion, the CPR training with detailed feedback devices provided motivation for learning and improving CPR proficiency than that with a basic control panel. Furthermore, the comments given from devices seemed to be more acceptable to the students, who did not see any bias in the device's evaluation compared to that of the instructor. Detailed device feedback motivates student health practitioners to learn and improve the overall quality of CPR. The use of mannequins that provide detailed feedback during BLS courses can improve survival in out-of-hospital cardiac arrest.

Is Physiological Equivalent Temperature (PET) a superior screening tool for heat stress risk than Wet-Bulb Globe Temperature (WBGT) index? Eight years of data from the Gothenburg half marathon.

BACKGROUND: The Wet-Bulb Globe Temperature (WBGT) index is a common tool to screen for heat stress for sporting events. However, the index has a number of limitations. Rational indices, such as the physiological equivalent temperature (PET) and Universal Thermal Climate Index (UTCI), are potential alternatives. AIM: To identify the thermal index that best predicts ambulance-required assistances and collapses during a city half marathon. METHODS: Eight years (2010-2017) of meteorological and ambulance transport data, including medical records, from Gothenburg's half-marathon were used to analyse associations between WBGT, PET and UTCI and the rates of ambulance-required assistances and collapses. All associations were evaluated by Monte-Carlo simulations and leave-one-out-cross-validation. RESULTS: The PET index showed the strongest correlation with both the rate of ambulance-required assistances (R2=0.72, p=0.008) and collapses (R2=0.71, p=0.008), followed by the UTCI (R2=0.64, p=0.017; R2=0.64, p=0.017) whereas the WBGT index showed substantially poorer correlations (R2=0.56, p=0.031; R2=0.56, p=0.033). PET stages of stress, match the rates of collapses better that the WBGT flag colour warning. Compared with the PET, the WBGT underestimates heat stress, especially at high radiant heat load. The rate of collapses increases with increasing heat stress; large increase from the day before the race seems to have an impact of the rate of collapses. CONCLUSION: We contend that the PET is a better predictor of collapses during a half marathon than the WBGT. We call for further investigation of PET as a screening tool alongside WBGT.
