Availability of social authorities in a simulated paediatric emergency.

INTRODUCTION: In cases of parental opposition to emergency medical care for minors, defined as children below 15 years of age, involving the social authorities may be necessary. When medical personnel assess that an intervention is in the minor's best interests, approval for such intervention is warranted from the local authorities in the municipality of residence. It was the primary aim of this study to assess the urgent availability of these authorities. METHODS: The urgent phone availability of social authorities at the 98 Danish local municipal offices was assessed during both regular hours and off-hours. The primary objective was to assess availability during regular hours. Urgent availability was predefined as obtained contact to a self-proclaimed accountable authority within 30 minutes. Secondary objectives were assessment of off-hour availability, time until obtained contact and number of contact links. RESULTS: Contact was obtained within 30 minutes in 59 inquiries (~ 58%) made during regular hours, with a median of three contact links and a median time until contact of eight minutes (interquartile range (IQR): 5.5-11 minutes). During off-hours, contact was obtained within 30 minutes in 91 inquiries (~ 93%), with a median of two contact links and a median time until contact of seven minutes (IQR: 5-12 minutes). CONCLUSION: During regular hours, we found that an accountable authority was urgently available for attendance to a case of parental opposition to emergency medical care of a minor within 30 minutes at the local municipal office in 58% of Danish municipalities. FUNDING: None. TRIAL REGISTRATION: Not relevant.

A high fraction of inspired oxygen may increase mortality in intubated trauma patients - A retrospective cohort study.

BACKGROUND: Mechanical ventilation of trauma patients is common, and many will require a higher than normal fraction of inspired oxygen (FiO2) to avoid hypoxaemia. The primary objective of this study was to assess the association between FiO2 and all-cause, one-year mortality in intubated trauma patients. METHODS: Adult trauma patients intubated in the initial phase post-trauma between 2015 and 2017 were retrospectively identified. Information on FiO2 during the first 24 hours of hospitalisation and mortality was registered. For each patient the number of hours of the first 24 hours exposed to an FiO2 ≥ 80%, ≥ 60%, and ≥ 40%, respectively, were determined and categorised into exposure durations. The associations of these FiO2 exposures with mortality were evaluated using Cox regression adjusting for age, sex, body mass index (BMI), Injury Severity Score (ISS), prehospital Glasgow Coma Scale (GCS) score, and presence of thoracic injuries. RESULTS: We included 218 intubated trauma patients. The median prehospital GCS score was 6 and the median ISS was 25. One-year mortality was significantly increased when patients had received an FiO2 above 80% for 3-4 hours compared to <2 hours (hazard ratio (95% CI) 2.7 (1.3-6.0), p= 0.011). When an FiO2 above 80% had been administered for more than 4 hours, there was a trend towards a higher mortality as well, but this was not statistically significant. There was a significant, time-dependent increase in mortality for patients who had received an FiO2 ≥ 60%. There was no significant relationship observed between mortality and the duration of FiO2 ≥ 40%. CONCLUSION: A fraction of inspired oxygen above 60% for more than 2 hours during the first 24 hours of admission was associated with increased mortality in intubated trauma patients in a duration-dependent manner. However, given the limitations of this retrospective study, the findings need to be confirmed in a larger, randomized set-up.
