Inter-disciplinary cooperation in a physician-staffed emergency medical system

Benefits of targeted deployment of physician-led interprofessional pre-hospital teams on the care of critically Ill and injured patients: a systematic review and meta-analysis

INTRODUCTION

Over the past three decades, more advanced pre-hospital systems have increasingly integrated physicians into targeted roles, forming interprofessional teams. These teams focus on providing early senior decision-making and advanced interventions while also ensuring rapid transport to hospitals based on individual patient needs. This paper aims to evaluate the benefits of an inter-professional care model compared to a model where care is delivered solely by paramedics.

METHODOLOGY

A meta-analysis and systematic review were conducted using the guidelines of PRISMA 2020. Articles were identified through a systematic search of three databases and snowballing references. A systematic review was conducted of articles that met the inclusion criteria, and a suitable subset was included in a meta-analysis. The survival and mortality outcomes from the studies were then pooled using the statistical software Review Manager (RevMan) Version 8.2.0.

RESULTS

Two thousand two hundred ninety-six articles were found from the online databases and 86 from other sources. However, only 23 articles met the inclusion criteria of our study. A pooled analysis of the outcomes reported in these studies indicated that the mortality risk was significantly reduced in patients who received pre-hospital care from interprofessional teams led by physicians compared with those who received care from paramedics alone (AOR 0.80; 95% CI [0.68, 0.91] p = 0.001). The survival rate of critically ill or injured patients who received pre-hospital care from interprofessional teams led by physicians was increased compared to those who received care from paramedics alone (AOR 1.49; 95% CI [1.31, 1.69] P < 0.00001).

CONCLUSIONS

The results of our analysis indicate that the targeted deployment of interprofessional teams led by physicians in the pre-hospital care of critically ill or injured patients improves patient outcomes.

Evaluating the impact of a specialized and centralized online medical consultation system for paramedics: pilot study

INTRODUCTION

There are many limitations to utilizing on-duty emergency department (ED) physicians as Base Hospital Physicians for paramedic telephone consultations. We aimed to examine the impact of a specialized and centralized Online Medical Consultation program for paramedic consultations on system-relevant performance.

METHODS

This is a before-after study with concurrent control using health record review of audio recordings over a 6-month period before and after implementation of the Online Medical Consultation program. The primary outcome was the duration of paramedic consultation calls. The secondary outcomes included number of calls with orders that contradicted existing medical directives, number of calls with orders outside of paramedic scope of practice, number of calls with Base Hospital Physician requiring clarification on medical directives, and number of calls with Base Hospital Physician interrupting the paramedic during the call.

RESULTS

We included 220 consultation calls. The patients' mean age was 54.5 years. Most consultation calls (70.5%) were for mandatory consultations and 22.7% were voluntary. Most consultations were related to cardiac arrest (43.6%), combative patients (15.0%), and analgesia (13.6%). Before-after comparisons for total call duration showed that mean call duration decreased in Ottawa from 4:28 to 4:05 min (p = 0.77) and decreased in Kingston from 4:50 to 4:13 min (p = 0.49). There were no significant differences in our secondary outcomes.

CONCLUSIONS

The Online Medical Consultation program was implemented and removed the responsibility of responding to online medical consultations for on-duty emergency physicians in Ottawa. The total call duration was not significantly different between groups. Additional time intervals and adherence to protocol benefits were also not statistically significant due to low baseline incidence.

Prevalence and severity of pediatric cases in Stockholm's physician-staffed prehospital units: a retrospective cohort study

BACKGROUND

Ambulance missions involving pediatric patients are common in emergency medical services (EMS) globally, with variations in prevalence based on geographic location. This retrospective cohort study analyzes the prehospital physician staffed units (p-EMS) in Stockholm, assignment dispatches and the prehospital characteristics and interventions involved, from January 1, 2021, to December 31, 2022.

METHODS

Utilizing data from LogEze, a quality assurance system, we reviewed all Rapid Response Vehicle (RRV) operations in the Stockholm Region, which totaled 4,682 pediatric assignments. The analysis included dispatch types and interventions assessing the frequency and nature of pediatric prehospital missions.

RESULTS

Pediatric cases constituted 20.0 % of RRV dispatches, with the majority involving respiratory distress, seizures, and blunt trauma. Despite high dispatch rates, advanced medical interventions were seldom required, indicating most pediatric cases were not severe. Stand-downs occurred in 30.1 % of cases, reflecting the cautious approach in pediatric dispatches. Furthermore, the study observed a significant reliance on p-EMS for complex pediatric cases, underscoring the value of specialized training and resources in managing such emergencies.

CONCLUSION

The study highlights the crucial role of p-EMS in enhancing pediatric emergency care in Stockholm. Despite frequent pediatric dispatches, the low incidence of severe cases underscores the need for precise triage and resource allocation. This analysis supports the need for continuous training and resource optimization in p-EMS to ensure high-quality care for pediatric patients across varied emergency scenarios.

Healing of Unilateral Maxillary Sinusitis by Endodontic and Periodontal Treatment of Maxillary Teeth

Inflammatory conditions of dental origin may spread to the bone tissue, causing its destruction, and to anatomical structures located in the vicinity of the tooth affected with inflammation. Maxillary premolars and molars may develop inflammatory lesions of the Schneiderian membrane and lead to tooth-borne lesions in the maxillary sinuses. Unilateral inflammation of the maxillary sinuses should be diagnosed and treated. The aim of this study was to determine whether and after what time from the applied endodontic or nonsurgical periodontal treatment the inflammation in the maxillary sinus was diminished (assessed by the decrease in the Schneiderian membrane hypertrophy). A retrospective study was performed to analyze the records of endodontically, periodontally, or endodontically-periodontally treated patients with unilateral inflammation of the maxillary sinuses along with diagnostic Cone Beam Computed Tomography. The method for determination of the inflammation was measurements registered in millimeters in Carestream software. The analysis included the situation before treatment and 3 months, 6 months, and 12 months after completion of the treatment. Regardless of the origin of the maxillary sinus lesion, healing of inflammation of the sinus has been reported after the implementation of causative treatment of the maxillary tooth. Dental treatment reduces the need to implement conservative or surgical ENT treatment.

Acute medical missions by helicopter medical service (HEMS) to municipalities with different approach for primary care physicians

Background

The prehospital emergency system in Norway involves out-of-hours (OOH) services with on-call physicians. Helicopter emergency medical service (HEMS) are used in cases of severe illness or trauma that require rapid transport and/or an anesthesiologist’s services. In recent years, on-call primary care physicians have been less available for call-outs in Norway, and HEMS may be requested for missions that could be adequately handled by on-call physicians. Here, we investigated how different availability of an on-call physician to attend emergency patients at site (call-out) impacted requests and use of HEMS.

Methods

Our analysis included all acute medical missions in an urban and nearby rural OOH district, which had different approach regarding physician call-outs from the OOH service. For this prospective observational study, we used data from both HEMS and the OOH service from November 1^st 2017 until November 30^th 2018. Standard descriptive statistical analyses were used.

Results

The rates of acute medical missions in the urban and rural OOH districts were similar (30 and 29 per 1000 inhabitants per year, respectively). The rate of HEMS requests was significantly higher in the rural OOH district than in the urban district (2.4 vs. 1.7 per 1000 inhabitants per year, respectively). Cardiac arrest and trauma were the major symptom categories in more than one half of the HEMS-attended patients, in both districts. Chest pain was the most frequent reason for an OOH call-out in the rural OOH district (21.1%). An estimated NACA score of 5–7 was found in 47.7% of HEMS patients from the urban district, in 40.0% of HEMS patients from the rural OOH district (p = 0.44), and 12.8% of patients attended by an on-call physician in the rural OOH district (p < 0.001). Advanced interventions were provided by an anesthesiologist to one-third of the patients attended by HEMS, of whom a majority had an NACA score of ≥ 5.

Conclusions

HEMS use did not differ between the two compared areas, but the rate of HEMS requests was significantly higher in the rural OOH district. The threshold for HEMS use seems to be independent of on-call primary care physician involvement.

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.

A Report Concerning Collaboration Between a Physician-Staffed Helicopter (Doctor Helicopter) and Police Helicopter

A 35-year-old man injured his right foot by slipping down 200 m into a crater on top of Mount Fuji, where some snow still remained. The next day the patient climbed up from the crater with his friend's assistance and began to descend the mountain; he met the Shizuoka police mountain distress rescue team at the 9th station. The Shizuoka police mountain distress rescue team transported the patient on foot to the snowless 7th station. The Shizuoka police aviation unit, flying a helicopter, then collected the patient. They transported the patient to the nearby Fujinomiya fire department station. The eastern Shizuoka physician-staffed helicopter emergency medical service landed there, and the patient was transported to Juntendo Shizuoka Hospital. On arrival, he had stable vital signs, but his right foot showed a dislocated fracture with frostbite. This is the first case report of collaboration between a helicopter emergency medical service and a police helicopter to rescue a victim from Mount Fuji. When managing victims in high-altitude settings, such as Mount Fuji, collaboration between multiple organizations is necessary.

Prehospital Stressors: A Cross-sectional Study of Norwegian Helicopter Emergency Medical Physicians

OBJECTIVE

Personnel working in helicopter emergency medical services (HEMS) and search and rescue (SAR) are exposed to environmental stressors, which may impair performance. The aim of this survey was to study the extent HEMS and SAR physicians report the influence of specific danger-based and non-danger-based stressors.

METHODS

The study was performed as a cross-sectional, anonymous, Web-based (Questback AS, Bogstadveien 54, 0366 Oslo, Norway) survey of Norwegian HEMS and SAR physicians between December 2, 2019, and February 25, 2020.

RESULTS

Of the recipients, 119 (79.3%) responded. In helicopter operations, 33.6% (n = 40) reported involvement in a minor accident and 44.5% (n = 53) a near accident. In the rapid response car, 26.1% (n = 31) reported near accidents, whereas 26.9% (32) reported this in an ambulance. Of physicians, 20.2% (n = 24) received verbal abuse or threats during the last 12 months. When on call, 50.4% (n = 60) of physicians reported sometimes or often being influenced by fatigue.

CONCLUSION

This study shows that Norwegian HEMS and SAR physicians are exposed to several stressors of both a danger-based and non-danger-based nature, especially regarding accidents, threatening patient behavior, and fatigue. Very serious incidents appear to be seldom, and job satisfaction is high.
