Background No consensus based national standard for interhospital transports of critically ill patients exists in Norway. The local hospitals are responsible for funding, organizing and performing these transports, resulting in potentially different level of care for the critically ill patients depending on local hospital resources and not the level of severity in the patient’s condition. The aim of this study was to examine how these transports are executed and to discover challenges during transports and potentials of improvement. Methods A qualitative study with 20 semi-structured interviews of doctors, nurses and ambulance personnel representing a wide range in experience and formal education, reflecting the different compositions of crews performing interhospital transports was conducted. A systematic text condensation of the interviews was performed to describe personal experiences and values. Results Few interviewees reported special adverse events when asked. Instead they chose to describe more general characteristics of the working environment, their own positive emotions or fears and the strengths and weaknesses of the organizational system. The prehospital working environment was described as different from the in-hospital environment. The personnel experienced being on their own during transports, lack of procedures and checklists and often no systematic education or demanded preparedness for participating. The resident doctors described pressure from elderly colleagues to participate in the transports. At the same time, all interviewees reported a self-interest in participating in these transports. Conclusions Safe interhospital transports of the critically ill patients are challenged by the characteristics of the out of hospital environment. The transports are described as potentially unsafe for both patients and personnel. Systematic education is warranted, highlighting the use of checklists and special educational programs in prehospital critical care medicine. The strong personal interest to participate in these transports may serve as a barrier against changing todays system. To ensure the right level of competence and safety for each unique patient, it is imperative to standardize the interhospital transports on a national level, built on consensus from experienced prehospital personnel.

Aims To measure and evaluate clinical response to nasal naloxone in opioid overdoses in the pre‐hospital environment. Design Randomised, controlled, double‐dummy, blinded, non‐inferiority trial, and conducted at two centres. Setting Participants were included by ambulance staff in Oslo and Trondheim, Norway, and treated at the place where the overdose occurred. Participants Men and women age above 18 years with miosis, rate of respiration ≤8/min, and Glasgow Coma Score <12/15 were included. Informed consent was obtained through a deferred‐consent procedure. Intervention and comparator A commercially available 1.4 mg/0.1 mL intranasal naloxone was compared with 0.8 mg/2 mL naloxone administered intramuscularly. Measurements The primary end‐point was restoration of spontaneous respiration of ≥10 breaths/min within 10 minutes. Secondary outcomes included time to restoration of spontaneous respiration, recurrence of overdose within 12 hours and adverse events. Findings In total, 201 participants were analysed in the per‐protocol population. Heroin was suspected in 196 cases. With 82% of the participants being men, 105 (97.2%) in the intramuscular group and 74 (79.6%) in the intranasal group returned to adequate spontaneous respiration within 10 minutes after one dose. The estimated risk difference was 17.5% (95% CI, 8.9%–26.1%) in favour of the intramuscular group. The risk of receiving additional naloxone was 19.4% (95% CI, 9.0%–29.7%) higher in the intranasal group. Adverse reactions were evenly distributed, except for drug withdrawal reactions, where the estimated risk difference was 6.8% (95% CI, 0.2%–13%) in favour of the intranasal group in a post hoc analysis. Conclusion Intranasal naloxone (1.4 mg/0.1 mL) was less efficient than 0.8 mg intramuscular naloxone for return to spontaneous breathing within 10 minutes in overdose patients in the pre‐hospital environment when compared head‐to‐head. Intranasal naloxone at 1.4 mg/0.1 mL restored breathing in 80% of participants after one dose and had few mild adverse reactions.

Background Less than 50% of stroke patients in Norway reach hospital within 4 h of symptom onset. Early prehospital identification of stroke and triage to the right level of care may result in more patients receiving acute treatment. Quality of communication between paramedics and the stroke centre directly affects prehospital on-scene time, emphasising this as a key factor to reduce prehospital delay. Prehospital stroke scales are developed for quick and easy identification of stroke, but have poor sensitivity and specificity compared to an in-hospital assessment with the National Institutes of Health Stroke Scale (NIHSS). The aim of the Paramedic Norwegian Acute Stroke Prehospital Project (ParaNASPP) is to assess whether a structured learning program, prehospital NIHSS and a mobile application facilitating communication with the stroke physician may improve triage of acute stroke patients. Methods A stepped wedge cluster randomised controlled intervention design will be used in this trial in Oslo, Norway. Paramedics at five ambulance stations will enrol adult patients with suspected stroke within 24 h of symptom onset. All paramedics will begin in a control phase with standard procedures. Through an e-learning program and practical training, a random and sequential switch to the intervention phase takes place. A mobile application for NIHSS scoring, including vital patient information for treatment decisions, transferring data from paramedics to the on-call stroke physician at the Stroke Unit at Oslo University Hospital, will be provided for the intervention. The primary outcome measure is positive predictive value (PPV) for prehospital identification of patients with acute stroke defined as the proportion of patients accepted for stroke evaluation and discharged with a final stroke diagnosis. One thousand three hundred patients provide a 50% surplus to the 808 patients needed for 80% power to detect a 10% increase in PPV. Discussion Structured and digital communication using a common scale like NIHSS may result in increased probability for better identification of stroke patients and less stroke mimics delivered to a stroke team for acute diagnostics and treatment in our population.

Background Amidst the ongoing opioid crisis there are debates regarding the optimal route of administration and dosages of naloxone. This applies both for lay people administration and emergency medical services, and in the development of new naloxone products. We examined the characteristics of naloxone administration, including predictors of dosages and multiple doses during patient treatment by emergency medical service staff in order to enlighten this debate. Methods This was a prospective observational study of patients administered naloxone by the Oslo City Center emergency medical service, Norway (2014–2018). Cases were linked to The National Cause of Death Registry. We investigated the route of administration and dosage of naloxone, clinical and demographic variables relating to initial naloxone dose and use of multiple naloxone doses and one-week mortality. Results Overall, 2215 cases were included, and the majority (91.9%) were administered intramuscular naloxone. Initial doses were 0.4 or 0.8 mg, and 15% of patients received multiple dosages. Unconscious patients or those in respiratory arrest were more likely to be treated with 0.8 mg naloxone and to receive multiple doses. The one-week mortality from drug-related deaths was 4.1 per 1000 episodes, with no deaths due to rebound opioid toxicity. Conclusions Intramuscular naloxone doses of 0.4 and 0.8 mg were effective and safe in the treatment of opioid overdose in the prehospital setting. Emergency medical staff appear to titrate naloxone based on clinical presentation.

Our findings suggest that the opening hours at the safe injection facility and the overdose location may impact the likelihood of ambulance transport for further treatment.
