Posttraumatic Stress Responses and Psychological Well-being in Norwegian Medical Helicopter Personnel.

OBJECTIVE: Emergency medical personnel are exposed to multiple stressors, including those of psychological etiologies. The aim of this study was to report the prevalence of anxiety, depression, and posttraumatic stress symptoms in Norwegian medical helicopter personnel and to determine to what degree they report personal growth or deprecation due to exposure to work-related events. METHODS: This was a web-based, cross-sectional survey performed among rescue paramedics and physicians staffing helicopter emergency medical services and search and rescue helicopters between May 5, 2021, and July 5, 2021. Questions included demographic data, the traumatic events exposure index, the Generalized Anxiety Disorder 7 scale, the Patient Health Questionnaire 9 (Depression), the posttraumatic change scale, and the posttraumatic symptom scale. RESULTS: Of the 245 eligible participants, 10 declined to take part and 74 failed to answer, producing a response rate of 66% (72 rescue paramedics and 89 physicians). Of the study population, 3.9 % reported manifest posttraumatic stress disorder symptoms, and 1.9% described moderate to severe depression and anxiety. The majority (76%) described posttraumatic emotional growth because of their work experience. CONCLUSION: Despite exposure to several traumatic stressors, participants reported a lower prevalence of posttraumatic stress symptoms, depression, and anxiety compared with a Norwegian adult population.

The effect of the new rescue helicopters on the rescue service's mission profile. / Nytt redningshelikopters innvirkning på redningstjenestens oppdragsprofil.

BACKGROUND: The change of rescue helicopter type from the Sea King to the SAR Queen has been controversial. Some hospitals can no longer receive rescue helicopters because of the stronger rotor downwash from the SAR Queen. For the same reason, it has been unclear whether the SAR Queen would be able to land near patients for air ambulance missions. The objective of the study was to investigate whether the change of helicopter type has changed the rescue service's mission profile. MATERIAL AND METHOD: Mission data from the first eight months with the SAR Queen at Ørland Air Base (14 May 2021-14 January 2022) were compared with the last equivalent period with the Sea King (14 May 2020-14 January 2021). RESULTS: The number of requests increased from 249 to 349 (40 %) after the introduction of the new rescue helicopter. Response time increased from 11 to 13 minutes (18 %), while the on-scene time remained unchanged at 10 minutes for primary missions and search and rescue missions. The patients' average degree of severity, assessed by NACA scores, remained unchanged at 3.7. The proportion of missions where hoisting of a rescue paramedic or a doctor was required to gain access to the patient remained unchanged. INTERPRETATION: The study showed that the use of the rescue helicopter at Ørland Air Base increased after the phasing-in of the SAR Queen. The service's mission profile remained the same. The unchanged proportion of missions that involved hoisting indicates that suitable landing sites close to the patients were found to the same extent as with the Sea King.

Patients with low-voltage electric shock referred to an Emergency Department. / Pasienter med strømgjennomgang fra lavspenning henvist til et akuttmottak.

BACKGROUND: Patients exposed to electricity are often referred to the Emergency Department, but guidelines differ as to how they should be managed. In this article, we describe patients with low-voltage electric shock in the Emergency Department at St Olav's Hospital, Trondheim University Hospital. MATERIAL AND METHOD: Retrospective data from patients referred to the Emergency Department following low-voltage electric shock (< 1,000 V) in the period 1.1.2012-31.12.2017 (N = 210) were included. RESULTS: The median age was 26 years and 186/210 (89 %) were men. Out of the 210 patients, 165 (79 %) had symptoms following electric shock. Localised pain and chest discomfort occurred in 84/165 (51 %) and 57/165 (35 %) of patients respectively. ECG findings were normal in 168/209 (80 %), and no patients had arrhythmias requiring treatment or elevated troponin T or creatine kinase. No patients had serious complications or died. INTERPRETATION: Low-voltage electric shock did not cause serious arrhythmias or elevated levels of troponin T or creatine kinase. It should be possible to manage asymptomatic patients with normal findings on clinical examination and ECG in a prehospital setting without reducing patient safety.

Patient visits to an emergency department in anticipation of the COVID-19 pandemic. / Pasienttilstrømming i et akuttmottak i påvente av covid-19-pandemien.

BACKGROUND: The Emergency Department in Trondheim has prepared for a large influx of patients infected with the SARS-CoV-2 virus. We conducted a study comparing patients in the Emergency Department in the first weeks of the pandemic in Norway (weeks 11 and 12) with the average number of patient visits. MATERIAL AND METHOD: Data from patients at the Emergency Department of St Olav's Hospital in the period 6 January 2020-22 March 2020 were retrieved from the Emergency Department's database. Logistical patient data concerning patient numbers, chief complaints, length of stay in the Emergency Department, acuity level, isolation status, and treatment level were analysed. RESULTS: In week 12, 331 patients were referred to the Emergency Department, a reduction of 39 % compared with the average of 541 patients in weeks 2-10. There was a general reduction in all patient groups, but particularly those discharged from the Emergency Department. In week 12 there were 56 more patients isolated with suspected/potentially infectious disease (187 %) compared with the average for weeks 2-10, and these patients spent almost two hours longer in the Emergency Department than other patients. INTERPRETATION: There was a reduction in patient visits to the Emergency Department in the first weeks of the pandemic. The percentage of patients isolated for infection control increased, and the time spent in the Emergency Department for these patients was greater than for other patients. The reduction in the inflow of patients is expected to be temporary, and the Emergency Department at St Olav's Hospital expects a large influx of patients with suspected COVID-19 disease.

Description of chest pain patients in a Norwegian emergency department.

OBJECTIVES: Chest pain is one of the most frequent chief complaints in patients admitted to the emergency department (ED). No study has evaluated this patient population in Norway. The aim of the present study was to describe the diagnoses and logistics of chest pain patients admitted to the ED at a Norwegian university hospital. DESIGN: Data were collected from all patients referred to the ED at St. Olav's Hospital-Trondheim University Hospital in 2015. Patients presenting at the ED with a chief complaint of chest pain based on the Rapid Emergency Triage and Treatment System were included in this study. RESULTS: In the study period, 22,403 patients were admitted to the ED. Chest pain was the second most common chief complaint (11%), only exceeded by acute abdominal pain (18%). Among the chest pain patients, 12% had acute coronary syndrome (ACS) and 37% were diagnosed with non-specific chest pain. Gastrointestinal, musculoskeletal, and pulmonary conditions were less common, affecting 6%, 4%, and 4% of the patients, respectively. In total, 90% of the ED chest pain patients were handled by the Clinic of Cardiology. CONCLUSIONS: Chest pain was the second most common chief complaint among patients admitted to the ED, and most patients were handled by the Clinic of Cardiology. More than one-third of the patients received a cardiac diagnosis, but the largest group of patients was discharged with a diagnosis of non-specific chest pain. Other conditions managed by non-cardiac medical specialties were less common.

Real-time forecasting of emergency department arrivals using prehospital data.

BACKGROUND: Crowding in emergency departments (EDs) is a challenge globally. To counteract crowding in day-to-day operations, better tools to improve monitoring of the patient flow in the ED is needed. The objective of this study was the development of a continuously updated monitoring system to forecast emergency department (ED) arrivals on a short time-horizon incorporating data from prehospital services. METHODS: Time of notification and ED arrival was obtained for all 191,939 arrivals at the ED of a Norwegian university hospital from 2010 to 2018. An arrival notification was an automatically captured time stamp which indicated the first time the ED was notified of an arriving patient, typically by a call from an ambulance to the emergency service communication center. A Poisson time-series regression model for forecasting the number of arrivals on a 1-, 2- and 3-h horizon with continuous weekly and yearly cyclic effects was implemented. We incorporated time of arrival notification by modelling time to arrival as a time varying hazard function. We validated the model on the last full year of data. RESULTS: In our data, 20% of the arrivals had been notified more than 1 hour prior to arrival. By incorporating time of notification into the forecasting model, we saw a substantial improvement in forecasting accuracy, especially on a one-hour horizon. In terms of mean absolute prediction error, we observed around a six percentage-point decrease compared to a simplified prediction model. The increase in accuracy was particularly large for periods with large inflow. CONCLUSIONS: The proposed model shows increased predictability in ED patient inflow when incorporating data on patient notifications. This approach to forecasting arrivals can be a valuable tool for logistic, decision making and ED resource management.

Low-voltage electric shock - proposed new recommendations. / Strømgjennomgang fra lavspenning ­ forslag til nye anbefalinger.

We propose new recommendations for the emergency treatment of low-voltage electric injuries (<1 000 volts). A large proportion of these patients can be treated as outpatients.

Using machine learning to assess the extent of busy ambulances and its impact on ambulance response times: A retrospective observational study.

BACKGROUND: Ambulance response times are considered important. Busy ambulances are common, but little is known about their effect on response times. OBJECTIVE: To assess the extent of busy ambulances in Central Norway and their impact on ambulance response times. DESIGN: This was a retrospective observational study. We used machine learning on data from nearby incidents to assess the probability of up to five different ambulances being candidates to respond to a medical emergency incident. For each incident, the probability of a busy ambulance was estimated by summing the probabilities of candidate ambulances being busy at the time of the incident. The difference in response time that may be attributable to busy ambulances was estimated by comparing groups of nearby incidents with different estimated busy probabilities. SETTING: Medical emergency incidents with ambulance response in Central Norway from 2013 to 2022. MAIN OUTCOME MEASURES: Prevalence of busy ambulances and differences in response times associated with busy ambulances. RESULTS: The estimated probability of busy ambulances for all 216,787 acute incidents with ambulance response was 26.7% (95% confidence interval (CI) 26.6 to 26.9). Comparing nearby incidents, each 10-percentage point increase in the probability of a busy ambulance was associated with a delay of 0.60 minutes (95% CI 0.58 to 0.62). For incidents in rural and urban areas, the probability of a busy ambulance was 21.6% (95% CI 21.5 to 21.8) and 35.0% (95% CI 34.8 to 35.2), respectively. The delay associated with a 10-percentage point increase in busy probability was 0.81 minutes (95% CI 0.78 to 0.84) and 0.30 minutes (95% CI 0.28 to 0.32), respectively. CONCLUSION: Ambulances were often busy, which was associated with delayed ambulance response times. In rural areas, the probability of busy ambulances was lower, although the potentially longer delays when ambulances were busy made these areas more vulnerable.

Patient visits to the emergency department at a Norwegian university hospital: variations in patient gender and age, timing of visits, and patient acuity.

BACKGROUND: The patient visits to Norwegian emergency departments (EDs) have increased significantly over the last few years. A national evaluation revealed a lack of systematic activity control, resource management and quality improvement. This paper describes some variables in patient visits to an urban Norwegian university hospital. METHODS: The retrospective data were collected from a database (Akuttdatabasen) and included all patients admitted to the main ED at the St. Olav's University Hospital between 1 December 2010 and 1 December 2011. RESULTS: ED visits have increased by 44% over the last decade and show considerable timely variations. Almost 50% of the patients are older than 65 years of age. The rate of patients triaged with the highest acuity level was 11%, but only 1.3% of the patients were admitted to the Intensive Care Unit (ICU). The total admission rate was 89%. CONCLUSIONS: The increase in ED visits to the St. Olav's Hospital in recent years follows the same trend as in other countries. The authors see a slightly higher percentage of high level acuity patients compared with international studies due the general practitioner's intended 'gatekeeper' function. The authors also found a high total admission rate and a low ICU admission rate compared with other countries. These differences cannot be explained solely by differences in the healthcare system in Norway. The cultural and traditional organisation of the Norwegian Health Care System needs to change and this creates an excellent opportunity to improve the competence by establishing emergency medicine as a specialty in Norway.

Comparison of intranasal and intramuscular naloxone in opioid overdoses managed by ambulance staff: a double-dummy, randomised, controlled trial.

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.
