- Rationale and aim: Ambulance staff, i.e. registered nurses and assistant nurses, receive assignments from emergency dispatch centres including information on level of priority, address and patient’s care requirements. One problem is that the preliminary information the dispatcher gives to the ambulance staff may be incomplete. The purpose of this study was to determine how ambulance staff base their assessments on incomplete preliminary information when assessing care requirements.Methods: Fifteen ambulance staff working at seven ambulance stations were interviewed for this study. Interviews were transcribed and analysed using content analysis.Results: Incomplete preliminary information means that ambulance staff may be misdirected. This means that if the preliminary information from the dispatcher is incomplete, the ambulance staff need to reassess, and this is perceived to be difficult. Ambulance staff tend to stick to the first initiative that is taken after they receive an alert from the dispatcher.Conclusions: When ambulance staff receive incomplete preliminary information, they need to consider the possibility of conducting a reassessment. Based on the results, there is a need for new procedures to improve preparedness to conduct a reassessment after receiving incomplete preliminary information.

- 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.
