Procedural sedation by advanced practice providers in the emergency medical service in the Netherlands: a retrospective study.

BACKGROUND: Procedural sedation and analgesia (PSA) is a technique of administering sedatives to induce a state that allows the patient to tolerate painful procedures while maintaining cardiorespiratory function, a condition that is frequently desired prehospital. Non-physician prehospital clinicians often have a limited scope of practice when it comes to providing analgesia and sedation; sometimes resulting in a crew request for back-up from physician-staffed prehospital services.". This is also the case if sedation is desirable. Advanced practice providers (APPs), who are legally authorized and trained to carry out this procedure, may be a solution when the physician-staffed service is not available or will not be available in time. METHODS: The aim of this study is to gain insight in the circumstances in which an APP, working at the Dutch ambulance service "RAV Brabant MWN" from January 2019 to December 2022, uses propofol for PSA or to provide sedation. With this a retrospective observational document study we describe the characteristics of patients and ambulance runs and evaluates the interventions in terms of safety. RESULTS: During the study period, the APPs administered propofol 157 times for 135 PSA and in 22 cases for providing sedation. The most common indication was musculoskeletal trauma such as fracture care or the reduction of joint dislocation. In 91% of the situations where propofol was used, the predetermined goal e.g. alignment of fractured extremity, repositioning of luxated joint or providing sedation the goal was achieved. There were 12 cases in which one or more adverse events were documented and all were successfully resolved by the APP. There were no cases of laryngospam, airway obstruction, nor anaphylaxis. None of the adverse events led to unexpected hospitalization or death. CONCLUSION: During the study period, the APPs performed 135 PSAs and provided 22 sedations. The success rate of predetermined goals was higher than that stated in the literature. Although there were a number of side effects, their incidences were lower than those reported in the literature, and these were resolved by the APP during the episode of care. Applying a PSA by an APP at the EMS "RAV Brabant MWN" appears to be safe with a high success rate.

A survey of the current nurse practitioner and physician assistant workforce in Dutch ambulance care.

Background: Dutch ambulance service faces future challenges due to acute care development, patient changes, demographics, increased ambulance runs and regional differences. Ambulance Care Netherlands published a framework titled "Pilot physician assistant and nurse practitioner ambulance care". Within this framework, a role is proposed so that their qualifications can provide solutions to future challenges. Despite the introduction of nurse practitioners and physician assistants into Dutch ambulance care, little is known about the effects of this introduction or the tasks these professionals perform. Nevertheless, they are being called upon, even though it is not known whether their potential contribution to the desired outcome described in the framework. Objective: This study aims to provide an overview of all nurse practitioners and physician assistants working in Dutch ambulance care and the tasks they perform. Design: We used a cross-sectional exploratory study design. The nurse practitioners and physician assistants participated in a structured telephone survey. Setting: Emergency ambulance services in the Netherlands. Participants: A total of 56 respondents participated in a telephone survey. Results: We found 53 nurse practitioners and 20 physician assistants working in Dutch ambulance care, 56 participated in the survey. Their performance of both direct care and indirect care tasks differed considerably. While some nurse practitioners and physician assistants were fully autonomous in-patient care, others were bound by regulations and restrictions. Conclusions: We found large variations between respondents in direct and indirect care task, number of working hours, and the different positions within the different Emergency ambulance services in the Netherlands. As a result, the established framework cannot presently function but can provide sound guidance to different ambulance services in positioning their nurse practitioners or physician assistants.

A Nationwide Retrospective Analysis of Out-of-Hospital Pediatric Cardiopulmonary Resuscitation Treated by Helicopter Emergency Medical Service in the Netherlands.

OBJECTIVE: There is generally limited but conflicting literature on the incidence, causes, and outcomes of pediatric out-of-hospital cardiac arrest. This study was performed to determine the incidence and outcome of pediatric out-of-hospital cardiac arrest reported by all helicopter emergency medical services in the Netherlands and to provide a description of causes and treatments and, in particular, a description of the specific interventions that can be performed by a physician-staffed helicopter emergency medical service. METHODS: A retrospective analysis was performed of all documented pediatric (0 < 18 years of age) out-of-hospital cardiac arrests from July 2015 to July 2017, attended by all 4 Dutch helicopter emergency medical service teams. RESULTS: Two hundred two out-of-hospital cardiac arrests were identified. The overall incidence in the Netherlands is 3.5 out-of-hospital cardiac arrests in children per 100,000 pediatric inhabitants. The overall survival rate for out-of-hospital cardiac arrest was 11.4%. Eleven (52%) of the survivors were in the drowning group and between 12 and 96 months of age. CONCLUSION: Helicopter emergency medical services are frequently called to pediatric out-of-hospital cardiac arrests in the Netherlands. The survival rate is normal to high compared with other countries. The 12- to 96-month age group and drowning seem to have a relatively favorable outcome.

Prehospital Management of Peripartum Neonatal Complications by Helicopter Emergency Medical Service in the South West of the Netherlands: An Observational Study.

OBJECTIVE: Emergency medical service (EMS) is responsible for prehospital care encompassing all ages, irrespective of injury cause or medical condition, which includes peripartum emergencies. When patients require care more advanced than the level provided by the national EMS protocol, an EMS physician-staffed Dutch helicopter emergency medical service (HEMS) may be dispatched. In the Netherlands in 2016, there were 21.434 planned home births guided by midwives alone without further obstetric assistance, accounting for 12.7% of all births that year. However, there are no clear data available thus far regarding neonates requiring emergency care with or without HEMS assistance. This article reviews neonates during our study period who received medical care after birth by HEMS. METHODS: A retrospective chart review was performed including neonates born on the day of the dispatch between January 2012 and December 2017 who received additional medical care from the Rotterdam HEMS. RESULTS: Fifty-two neonates received medical care by HEMS. The majority (73.1%) were full-term (Gestational age > 37 weeks). Home delivery was intended in 63.5%, 20% of whom experienced an uncomplicated delivery but had a poor start of life. The majority of unplanned deliveries (n = 17) were preterm (70.6%). Two were born by resuscitative hysterotomy; 1 survived in good neurologic condition, and the other died at the scene. Fifteen neonates (28.9%) required cardiopulmonary resuscitation; in 2 cases, no resuscitation was started on medical grounds, and 12 of the other 13 resuscitated neonates regained return of spontaneous circulation. In 33 (63.5%) of the neonates, respiratory interventions were required; 8 (15.4%) were intubated before transport. Death was confirmed in 5 (9.6%) neonates, all preterm. CONCLUSION: During the study period, 52 neonates required medical assistance by HEMS. The 5 infants who died were all preterm. In this cohort, adequate basic life support was implemented immediately after birth either by the attending midwife, EMS, or HEMS on arrival. This suggests that prehospital first responders know the basic skills of neonatal life support.

A Physician-Based Helicopter Emergency Medical Services Was Associated With an Additional 2.5 Lives Saved per 100 Dispatches of Severely Injured Pediatric Patients.

OBJECTIVE: Physician-based helicopter emergency medical services (HEMS) provide specialist medical care to the accident scene in order to improve the survival of severely injured patients. Studies that focus on the role of physician-based HEMS in pediatric trauma are scarce. The aim of this retrospective, observational study was to determine the effect of physician-based HEMS assistance on the survival of severely injured pediatric patients. METHODS: All consecutive severely injured pediatric patients (age < 18 years and Injury Severity Score > 15) treated between October 1, 2000, and February 28, 2013, were included. The survival of patients who received medical care of physician-based HEMS was compared with the survival of patients treated by an ambulance paramedic crew (ie, emergency medical services group) only. A regression model was developed for calculating the survival benefit in the physician-based HEMS group. RESULTS: A total of 308 patients were included; 112 (36%) were primarily treated by emergency medical services, and 196 (64%) patients received additional physician-based HEMS assistance on scene. The model with the best diagnostic properties and fit contained physician-based HEMS assistance, 3 components of the Glasgow Coma Scale (eye, motor, and verbal) scored prehospitally (before intubation), ordinal values for the Injury Severity Scale, systolic blood pressure, and respiratory rate. This model predicted that 5 additional patients survived because of physician-based HEMS assistance. This corresponds with 2.5 additional lives saved per 100 physician-based HEMS dispatches for severely injured pediatric patients. CONCLUSION: The data suggest that an additional 2.5 lives might be saved per 100 physician-based HEMS dispatches for severely injured pediatric patients.

Are on-scene blood transfusions by a helicopter emergency medical service useful and safe? A multicentre case-control study.

INTRODUCTION: In the prehospital setting, crystalloid fluids are frequently used, but only erythrocytes are capable of transporting oxygen to tissues. The aim of this study was to establish the efficacy and safety of the prehospital use of uncross matched type O rhesus-negative packed red blood cells (URBC) by the Dutch physician-staffed helicopter emergency medical service. We hypothesized that prehospital URBC transfusions are safe and more effective with respect to survival than resuscitations with crystalloids. METHODS: The effects of prehospital URBC transfusions were studied by comparing a cohort of patients (>18 years) who were treated with a combination of URBC and crystalloid fluids with a matched control group of patients who received crystalloid fluids alone. RESULTS: Among 73 adults who received prehospital URBC transfusions, 50 (68%) patients were included. No transfusion reactions were observed. No effect of prehospital transfusion on 24-h or 30-day survival was found. Haemoglobin levels at presentation to the emergency department were higher in the URBC cohort. The two groups had similar cumulative erythrocyte requirements within the first 24 h. CONCLUSION: Neither survival benefits nor a decreased incidence of shock on admission were observed after prehospital helicopter emergency medical service URBC transfusions. There were no prehospital transfusion reactions in this study; therefore, URBC transfusions were deemed to be safe. A prospective randomized study is warranted to evaluate the effect of early URBC transfusions and transfusions with preheated URBC on the survival of patients with severe prehospital haemorrhagic shock.

Prehospital Blood Transfusions in Pediatric Patients by a Helicopter Emergency Medical Service.

OBJECTIVE: In the prehospital setting, the Nijmegen and Rotterdam helicopter emergency medical services administer packed red blood cells to critically ill or injured pediatric patients. Blood is given on scene or during transport and is derived from nearby hospitals. We summarize our experience with prehospital blood use in pediatric patients. METHODS: The databases from both the Nijmegen and Rotterdam helicopter emergency medical services were reviewed for all pediatric (< 18 years) patients who received packed red blood cells on scene or during transport to the hospital. RESULTS: Between 2007 and 2015, 10 pediatric patients out of approximately 2,400 pediatric patients received blood in the prehospital setting. The median Injury Severity Score was 41. Seven hospitals delivered blood in the prehospital setting at the scene. All patients were in hypovolemic shock. Two patients died. Two patients were believed to be unexpected survivors; 1 was predicted by the Trauma and Injury Severity Score, and a second unexpected survivor was a neonate who was in hypovolemic shock and cardiopulmonary arrest. CONCLUSION: The incidence of prehospital use of blood in injured or critically ill children is low. This intervention presented a potential to limit acid-base disturbance, low hemoglobin levels, and coagulopathy in this group. We believe this cohort also contains 2 unexpected survivors.
