INTRODUCTION

Nursing is a profession in constant transformation, which has its history marked by its integration into new locations of action and care scenarios. According to the Resolution of the Federal Nursing Council (COFEN) n ° 389/201, 42 nursing specialties exist in Brazil, and one of these specialties is Aerospace Nursing^1-3.

The pre-hospital and inter-hospital care, by means of air vehicles in Brazil, is expanding due to the dimension of the territory, geographical distances, and difficulties of urban traffic in large cities. In addition, there is also an increase in the demand for care due to clinical and traumatic emergencies, whose patients require rapid treatment and referral to hospital emergency services^1,3.

The medical transport aircraft service is part of the mobile pre-hospital component of the emergency care services network, provided by the National Emergency Care Policy, in Brazil, in 2003. The medical transport aircraft is classified as a “Type E” ambulance, which can be a rotary-wing aircraft, which is used for both inter-hospital and rescue operations, or a fixed wing aircraft, which performs the first type of operation cited. Both must be equipped with medical equipment approved by the National Civil Aviation Agency (Agência Nacional de Aviação Civil - ANAC)⁴.

Nursing practice in the mobile pre- and inter- hospital care in fixed and/or rotary wing aircraft requires previous experience in pre-hospital and hospital contexts, for the development of specific skills and abilities, such as: decision making, teamwork, rapid intervention, and evaluation of patients’ clinical conditions^1,5-7. In addition, the nurse develops activities related to planning, organization, and provision of resources for comprehensive and safe patient care^1,8.

The adequate performance of nurses’ activities within the aerospace crew is directly related to the search for continuous professional qualification, for development of excellent care^1,3,7. However, the regulation of nurses’ activities in pre- and inter- hospital care in air vehicles was only endorsed in 2017, by COFEN Resolution No. 0551⁸, and scientific publication on the subject is still scarce, mainly in Brazil. It is also important to consider that the aerospace context is a psychologically and physiologically stressful work environment for professionals, depending on the conditions under which the care is performed^6-7.

The aerospace environment is a relatively recent work setting, with great potential for expansion, which needs trained nurses to deal with the challenges inherent in this scenario. Thus, it is necessary to deepen the knowledge about the role of the nurse in the aerospace environment, and to identify whether the activities performed are in line with professional legislation. Knowledge of the nurse’s role, as a member of the on-board team, can contribute to the qualification of their professional practice and the construction of their professional identity³.

Based on the exposed position, the guiding question of this study was: What are the most frequent activities performed by nurses in the aerospace environment?

OBJECTIVES

To characterize the nurses who work in the aerospace environment, and to identify the most frequent actions performed by them during the pre-flight, flight and post-flight periods.

METHODS

Ethical aspects

The study met the ethical precepts of human research in Brazil, and was approved by the Research Ethics Committee of the Federal University of Santa Catarina. All the participants accepted to participate in the study, by agreement with a Free and Informed Consent Form online.

Design, place of study and period

This was a quantitative, exploratory-descriptive research design, implemented by means of an online survey, using Google forms^®. A virtual questionnaire was chosen, mainly, to increase the access of nurses throughout the national territory. Thus, the study was not restricted to a specific location.

Sample, inclusion and exclusion criteria

Data collection was performed from January to April of 2018. The study participants were nurses, working in pre-hospital mobile and inter-hospital care, in fixed and/or rotary wing aircraft, in public or private institutions in Brazil.

The lack of information about pre-hospital and inter-hospital services on aircraft in Brazil made it difficult to recruit nurses directly from institutional employers, or to perform a sample calculation to define the participants of the study. For identification and selection of participants, the link to the survey questionnaire was published on these social networks: Facebook®, Instagram® and Linkedin®. In addition, electronic contact was made with representative professional organizations and with research groups registered in the Directory of Research Groups in Brazil, of the National Council of Scientific and Technological Development, with lines of research related to the subject. From these strategies, a convenience sample of 50 participants was obtained.

As inclusion criterion, we considered: being a nurse in the pre-hospital mobile and inter-hospital care, in fixed-wing and/or rotating aircraft, during the data collection period. Questionnaires with incomplete information were excluded.

Study Protocol

An online form was developed for data collection, with two parts: 1) Sociodemographic and professional characteristics data: sex, age, academic formation, complementary education, time since receiving undergraduate degree, region of the country where working, type of institution, type of aircraft, prior training, other employment relationships, income and weekly workload; and 2) Professional practice, consisting of 13 questions related to the pre-flight (eight), in-flight (four), and post-flight (four) responsibilities, established in COFEN Resolution No. 0551/2017⁹.

The nurses provided the frequency with which they performed the activity listed in each question, using a Likert scale with five options: never, rarely, sometimes, often, and always. The data collection instrument was completed, voluntarily, by means of electronic contact, in a form linked to an initial message, which contained an invitation to participate in the research. Before the data collection, the instrument was tested with two nurse experts in the area, who did not participate in the study. No changes were necessary to the instrument after this pre-test.

Analysis of the results and statistics

The quantitative data obtained were organized in a spreadsheet and exported to the SPSS software, version 19.0. Descriptive statistics were used for presentation and analysis of the categorical variables, to calculate the frequency, in absolute number and percentage. For continuous variables, the measurements of position (mean, minimum and maximum) and dispersion (standard deviation) were analyzed.

RESULTS

Among the 50 nurses participating in the research, 32 (64%) were males, with a mean age of 37 years. The mean time of experience as a nurse was 10 years, with a mean of six years working in the aerospace environment. Most of them worked in the southern region of Brazil (42%), in services linked to public institutions (68%), and in rotary wing aircraft (54%). When entering the service, 39 (78%) of the nurses reported having received prior training. The mean weekly workload was 37 hours. The monthly income of 21 (42%) of the nurses was between three and five times the minimum wage (Table 1).

DISCUSSION

The characteristics of the nurses showed a predominance of male participation in the aerospace environment, contrary to the profile of Brazilian nursing, in which the female presence is dominant¹⁰. This result confirms the greater integration of men in nursing focuses on scenarios whose empirical understanding is the need for characteristics considered masculine, that is, that demand for physical strength, tenacity, and management of emotions^11-12, such as: psychiatric emergency and emergency services¹³, intensive care units (ICUs)¹⁴, and mobile emergency care services^15-16.

This area of nursing activity contributes to and, to a certain extent, reinforces the necessary gender debate in the profession. The deconstruction of preconceived ideas about femininity and masculinity in nursing enables the fragmentation of gender stereotypes, even allowing the end of inequalities in labor relationships¹⁷.

The sample consisted predominantly of nurses in the professional maturity stage, characterized by the full development of cognitive, technical, and practical abilities^10,15. Regarding professional experience, the mean time of participants as nurses was ten years, with a six years mean of working in aircraft. Additionally, some of them had considerable accumulated professional experience. Similar results were described in a study on the profile of nurses from the mobile emergency care service of Santa Catarina, Brazil¹⁵.

Regarding the region of actuation, 84% of the respondents were from the south, southeast, center-west, and federal district. This result may be associated with the concentration of nurses in these localities¹⁰. In addition, these regions are among the most urbanized in the country, which requires the state to provide and structure public policies to meet demands related to infrastructure, urban mobility, health, and public safety^18-19. In this sense, advanced life support care, by means of aircraft, reduces the response time for care and transfer to referral hospitals in large urban centers²⁰.

Regarding the type of institution and aircraft, the majority of nurses worked in public services (68%), and in rotating wing aircraft (54%). The numbers related to the first group can be explained by their linkage to public safety sectors in Brazil, such as the Brazilian Air Force (FAB), the Military Police, and the Fire Brigade²¹. Consequently, the use of airplanes is shared between public health and safety services, and is used not only for emergency services, but also in police operations, multimission, surveillance, and troop transport¹⁸. For these purposes, rotary-wing aircraft facilitate the movement and access to difficult-to-reach places, as they perform vertical landings without the need for a runway²¹.

Other data to be highlighted are that part of the nurses who are participants of this study started their activities without previous qualification. This finding can be considered alarming, considering the specificities of the work and the severity of the consultations performed in the aerospace environment. Lack of prior training was evidenced among nurses from the mobile emergency service in Santa Catarina, Brazil¹⁵, and health professionals from the air transportation of patients from a private company in Belo Horizonte, Brazil²².

The nurses’ weekly workload was approximately 36 hours, and an expressive part stated having another employment relationship. These results differ from studies in other work settings, in which the workload predominates, but with a unique professional link^14-15. This finding can be related to the specificities of the work in the aerospace environment, in which the regime of work by shifts and on-call are common.

Monthly income is difficult to compare, because nursing does not have a minimum wage in Brazil. However, it is known that remuneration which conflicts with the working hours can lead to two or more employment positions and long working hours, which can negatively impact the health of the professional and, consequently, the quality of the care provided¹⁴.

The academic education focused on the “lato sensu” graduate degree in intensive care or urgent care/emergency. A small portion of the sample were specialists in aerospace nursing, which can be attributed to the fact that specialization courses in this area are still insufficient in Brazil, considering that this is a relatively new specialty. In addition, many nurses in this area have had previous experiences in other intensive care settings, which justifies specialization courses in these areas^3,8,23.

In addition to the academic education, the search for complementary and specific courses to perform Advanced Life Support was identified, such as the Prehospital Trauma Life Support, which qualifies professionals for trauma care, and Advanced Cardiac Life Support, which aims at the development of basic and advanced life support skills for the treatment of acute cardiovascular events²³. The search for these courses for professional improvement in the urgent care and emergency area was also identified in a survey of nurses from a private pre-hospital care service in the interior of Rio Grande do Sul, Brazil³. In addition, these courses are considered short-term and, for many, economically more affordable, compared to “lato sensu” graduate degree courses.

The interest in complementary education can also be associated with the need for specific knowledge according to the area of professional integration into the labor market after completion of the undergraduate degree. Thus, nursing care in the air service requires special formation and constant updating to attend to complex and unpredictable situations^3,14,23-24.

In general, the result of this research show that nurses who practice in the aerospace environment contemplate what is provided by COFEN Resolution 0551/2017⁹.

In the pre-flight stage, the most frequent activity by the participants was the verification and testing of the functionality of each device. Previous studies on the performance of the aeromedical service in Brazil^1,3,8 emphasize the importance of nurses in estimating and providing materials and equipment in the management of supplies in health services. The responsibility for testing the rescue bags, checking materials and supplies, and examination of equipment functionality should be shared with the onboard physician team, minimizing the possibility of errors, and increasing the safety for the patient^22,25. Patient safety actions begin in aeromedical transport in the pre-flight phase, by means of proper planning of care in conjunction with the multidisciplinary team, and continues during the flight²⁶.

During the flight, integral patient care was demonstrated as the main activity of the nurses. Nursing documentation, in an objective, clear, and precise manner, is a routine assignment performed by the participants of this study. The Resolution of COFEN no358/2009 reinforces the importance and the need of planning nursing care, and postulates that the implementation of the Systematization of Nursing Care (SAE) must occur in every public and private health institution. Even in the face of the specificities of the aerospace environment, the development of SAE is possible. It begins with pre-flight patient evaluation, care planning, and information on the clinical course of the patient during the removal and provision of data to the target institution^1,23.

The activity performed with the least frequency during the flight was the administration of medications. This can indicate that most of the time the patient is stabilized on the ground, with no procedures required during the flight. In this sense, a study on emergency interventions in trauma victims of an aeromedical service demonstrated that the most frequent procedure was peripheral venous puncture for volume replacement or pre-flight medications²⁷.

In the post-flight, the main activity of the nurse was the replacement of supplies and equipment used, according to institutional protocol. This finding has also been identified in other studies on the subject, in which the disinfection, sterilization, and replacement of materials used, according to routines and documents of the institution, were presented as nursing activities in the post-flight stage^26-27. The administration characteristic of nurses is demonstrated in this care scenario, mainly regarding the management of materials, supplies, and equipment used during care.

In the post-flight period, the nurse is also responsible for the nursing care provided, documentation the patient’s data in the patient record, and requesting the signature of the physician responsible for the patient in the hospital²³.

The nurses’ performance in pre-hospital mobile and inter-hospital services in aircraft, and the activities of service planning are shown as differentials for professional practice and execution of safer care during all the care performed.

Limitations of the study

The scarcity of information related to pre-hospital and inter-hospital services on aircraft in Brazil made it difficult to recruit participants from the institutions. In addition, while online data collection facilitates access to potential study participants, one cannot control who the respondent is. With regards to the origin of the respondents, the professional relationship of the researchers may have contributed to a higher rate of respondents from the Southern Region of Brazil.

Contributions to the nursing area, health or public policy

Although a regulation by COFEN regarding the nurses’ activities in pre-hospital and inter-hospital care in air transport vehicles is already available, this study provides an overview of which activities are the most frequent, and can subsidize the preparation of future nurses interested in working in this area. Thus, the findings of the present study can contribute to the dissemination and expansion of aerospace nursing as a professional field in Brazil. As suggestions for further studies, it is necessary to investigate the nurses’ working conditions in the aerospace environment, aiming for safe, quality care.

CONCLUSIONS

The workforce of nurses in the aerospace environment is mostly male, with adequate academic/complementary education to perform in critical care settings. Among the nurses’ attributions, organizational and victim care actions were found during all stages of flight, resulting in comprehensive and safe care for the victims receiving treatment.
