QUALITY OF LIFE OF NURSES FROM THE MOBILE EMERGENCY CARE SERVICE

CALIDAD DE VIDA DE LOS ENFERMEROS DEL SERVICIO DE ATENCIÓN MÓVIL DE EMERGENCIAS

ABSTRACT

Objective:

to evaluate the quality of life of nurses from the Mobile Emergency Care Service of the Federal District (Brazil) and to identify the domains that influenced this assessment.

Method:

an observational, descriptive, cross-sectional and quantitative study, with data obtained from 123 nurses who answered a questionnaire developed and structured in order to know sociodemographic and clinical variables and with the application of the World Health Organization Quality of Life Instrument Bref, to assess the quality of life. The data were submitted to descriptive statistics and inferential statics.

Results:

most of the nurses were women, aged between 20 and 40 years old, married, with a specialization degree and without any employment relation with another institution. Most (72.36%) considered their quality of life good or very good and were satisfied or very satisfied with their health (65.03%). The environment domain was the worst evaluated. A significant correlation was observed between the social relations (p=0.049) and environment (p=0.035) domains when correlated with the gender variable. The women rated their social relations and environment better than the men.

Conclusion:

the knowledge produced by this investigation may support the design of strategies that enable reducing the difficulties related to the life and work of nurses of the Mobile Emergency Care Service. Actions in this direction may contribute to the improvement of health, well-being and quality of life of the professionals and will have positive effects on the quality of health care provided to the population.

INTRODUCTION

The Mobile Emergency Care Service (Serviço de Atendimento Móvel de Urgência, SAMU) is the mobile assistance component of the Emergency Care Network and aims to enable immediate response to the health demands of the population. Regulated by Ordinance No. 1010/GM, the main function of the SAMU is to order assistance as a form of rapid response to urgent demands, whether at home, at work or on public roads.11.

According to Resolution No. 375/2011 (Brazil), the presence of nurses in pre-hospital care (PHC) and inter-hospital care in situations of known or unknown risk is indispensable. In this context, the professional assumed nursing responsibilities and coordination, continuing education and service management activities, as established by the SAMU statute and the Professional Exercise Law and Code of Ethics of the Nursing Professionals.33.

In addition to these difficulties, there are the adversities resulting from acting in PHC, which include emotional tensions, inadequate working conditions, exposure to infections, contaminated biological material and chemicals, stress, hard to reach places and violence.88.

the nurses included in PHC may present different perceptions about their QoL, since this assessment is obtained from multiple factors, including the following: family, environment, culture, leisure, education, government policies, and one's own conditions, such as health and work conditions, as stress.1111. The WHOQOL Group. Development of the World Health Organization WHOQOL-BREF Quality of Life Assessment. Psychological Medicine [internet]. 1998 [cited 2017 June 11]; 28:551-8.

https://dx.doi.org/10.1017/S003329179800...

The World Health Organization (WHO) group of scholars, The World Health Organization Quality of Life - WHOQOL Group (1994) defined QoL as: “an individual's perception of his or her position in life in the context of the culture they live in, and in relation to their goals, expectations, standards and concerns”.1111. The WHOQOL Group. Development of the World Health Organization WHOQOL-BREF Quality of Life Assessment. Psychological Medicine [internet]. 1998 [cited 2017 June 11]; 28:551-8.

A subjective, multidimensional concept that addresses positive and negative elements in the assessment.1111. The WHOQOL Group.

From the definition of QoL, it was possible to build assessment instruments applicable to various populations, with different sociocultural realities. The first tool created was (WHOQOL 100). Subsequently, the abbreviated version of this instrument emerged, the Word Health Organization Quality of Life Instrument Bref (WHOQOL-BREF). This instrument was translated and validated for use in Brazil by a group of researchers from the Federal University of Rio Grande do Sul1212.

that assess the QoL of nurses working in PHC. However, few use the WHOQOL-BREF as an evaluation tool, which demonstrates the importance of this investigation. In this context, the objective of this research was to evaluate the QoL of nurses of the Federal District’s Mobile Emergency Care Service (Serviço de Atendimento Móvel de Urgências do Distrito Federal, SAMU DF) and to identify the domains that positively and negatively influence this assessment.

METHOD

This was an observational, exploratory, descriptive, and cross-sectional study with a quantitative approach, conducted with nurses from the SAMU DF (Brazil) in 2016.

The nurses of the SAMU DF, as professionals working in the PHC, have an operational base in the Prehospital Support Centers (Núcleos de Apoio Pré-Hospitalar, NAPHs), distributed in the administrative regions of the DF, in the Teaching and Research Center (Núcleo de Ensino e Pesquisa, NEP), in the Trauma Center and in the Neurocardiovascular Center (Hospital de Base do Distrito Federal, HBDF), in emergency hospital care and network support, at the Emergency Center of Guará (Hospital Regional do Guará, HRG) and in the specialized care in psychiatric emergencies at the Mental Health Center (Núcleo de Saúde Mental, NUSAM).

The study included nurses who were effective members of the service, enrolled at the Health Secretariat of the Federal District (Secretaria de Estado de Saúde do Distrito Federal, SES/DF) and registered at the Regional Nursing Council of the Federal District (Conselho Regional de Enfermagem do Distrito Federal, COREN/DF) as higher education professionals. Thus, the study population had 160 invited professionals, among which: nine were on maternity or health leave, two were no longer working at the SAMU DF, five refused to participate in the survey and 16 were not found, totaling 128 respondents. Of these, five had the questionnaires invalidated (missing values), leaving 123 nurses in the sample studied.

The professionals were invited to participate in the study during a course offered by the SAMU DF, in which the researchers had the opportunity to talk about the investigation along with an e-mail individually sent. Data collection was performed in a reserved place, during a day and time scheduled with the professionals, taking into consideration the scale and availability, aiming at not interfering in the dynamics and routine of the service. The completion of the instrument was followed by the researcher and performed only after proper research guidelines and signing of the Free and Informed Consent Form (FICF).

In order to know the sociodemographic and clinical aspects, a specific instrument was created with data regarding the following: gender, age, place of birth, origin, marital status, number of children, working time at the SAMU/DF, PHC Center in which he/she works, other employment (or two enrollments at the SES/DF), time of graduation, postgraduate completion, presence of chronic disease and continuous use of medication.

In order to assess QoL, WHOQOL-BREF was used. The instrument contains 26 questions, of which 24 are distributed in four domains: physical, psychological, social relations and environment. The other two questions relate to quality of life and health in general.1818. Costa KNFM, Costa TF. Quality of life related to the health of nursing professionals. Rev enferm UFPE on line [Internet]. 2017 [cited 2018 May 14]. 11(2):881-9. Available from: https://dx.doi.org/10.5205/1981-8963-v11i2a13456p881-889-2017
https://dx.doi.org/10.5205/1981-8963-v11...

The domains are represented by facets referring to each question. The questions were formulated for a Likert type response scale, assessed by the following response categories: 1) intensity, represented by the range - nothing to extremely, 2) ability, nothing to completely, 3) frequency, never to always and 4) rating, very dissatisfied to very satisfied or very bad to very good.1313. Pereira EF, Teixeira CS, Santos A. Quality of life: approaches, concepts and assessment. Rev Bras Educ Fís Esporte [Internet]. 2012 [cited 2017 June 20]; 26(2):241-50. Available from: https://dx.doi.org/10.1590/S1807-55092012000200007
https://dx.doi.org/10.1590/S1807-5509201...
This instrument assesses different social and cultural backgrounds and has gained special prominence in the health field due to the need for broader group and community assessments.1414. Conceição MR, Costa MS, Almeida MI, Souza AMA, Cavalcante MBPT, Alves MDS. Quality of life for nurses when teaching professionaly: a study with the WHOQOL-BREF. Esc Anna Nery [Internet]. 2012 [cited 2017 June 20]; 16(2):320-5. Available from: https://dx.doi.org/10.1590/S1414-81452012000200016
https://dx.doi.org/10.1590/S1414-8145201...

Data was analyzed using the Statistical Package for Social Sciences (SPSS) statistical program, version 24.0. The statistical analyses performed included descriptive analyses of frequency, central tendency and dispersion, inferential analyses, comparison among domains and correlations.

From the values found for each of the 24 facets that make up the domains, the mean values of the answers were obtained. The values indicate 1 as the worst answer and 5 as the best answer, which made it possible to verify which facets received positive and negative evaluations. For uniformity and comparison purposes, the mean values presented in the facets related to pain and discomfort, dependence on treatments or medications and negative feelings were analyzed in an inverted manner, according to the guidance from the WHO.1111. The WHOQOL Group. Development of the World Health Organization WHOQOL-BREF Quality of Life Assessment. Psychological Medicine [internet]. 1998 [cited 2017 June 11]; 28:551-8. Available from: https://dx.doi.org/10.1017/S0033291798006667
https://dx.doi.org/10.1017/S003329179800...
The calculations of the QoL assessment scores were made separately for each of the four domains, since a global QoL score is not conceptually provided in the instrument. The raw score was transformed to a scale of 4 to 20, according to the SPSS syntax proposed by the WHO.1111. The WHOQOL Group. Development of the World Health Organization WHOQOL-BREF Quality of Life Assessment. Psychological Medicine [internet]. 1998 [cited 2017 June 11]; 28:551-8. Available from: https://dx.doi.org/10.1017/S0033291798006667
https://dx.doi.org/10.1017/S003329179800...
Thus, the minimum score for each domain was 4 and the maximum was 20, so that the higher the score, the more positive the assessment of the domain.

To verify if there were differences among the domains, the Friedman ANOVA test was adopted. When proceeding with the correlations among the WHOQOL-BREF domains and the sociodemographic and clinical variables, the Mann-Whitney U test was used in the analyses with two independent samples and the Kruskal-Wallis test in the analyses with more than two independent samples.

RESULTS

Sociodemographic and clinical profile

The characterization of the studied sample demonstrated that the SAMU/DF team of nurses was composed mostly of women (74%) aged between 20 and 40 years old, married (63.4%), working at least for 4 years (41.5%) at the SAMU and without any other employment relation (65.9%).

Regarding the workplace, 43.9% worked in the mobile services, 38.2% in fixed emergencies like the Trauma center and the Neurocardiovascular Center (HBDF) and the Emergency Center of Guará (HRG) and 17.9% in the regulation, management or education areas.

With regard to academic training, a large part of the studied population (90.2%) had graduated more than 5 years ago. Most (70%) had a specialization degree, while few had a residency (5.7%), a master (5.7%) and a doctorate (0.8%).

Regarding health, it was observed that 15.4% had some chronic disease and 30.1% used some type of medication continuously.

QoL assessment

The WHOQOL-BREF instrument has two general questions. The first addresses quality of life and highlighted that 72.36% of the nurses consider it good or very good. The second assesses satisfaction with the health conditions, and showed that 65.03% of the respondents were satisfied or very satisfied with their health. Table 1 summarizes the WHOQOL-BREF domain and facet scores.

Table 1
Distribution of the mean values, standard deviations, minimum and maximum values and amplitude of the domains and facets of the WHOQOL-BREF of the nurses working in the SAMU DF. Brasilia, DF, Brazil. 2016. (n=123)

In Table 1, it is important to highlight the facets that negatively influenced the evaluation. Pain and discomfort, and dependence on treatments and medications, presented scores with mean values of 1.94 and 1.88, respectively. The negative feeling facet had a mean value of 2.27, while the physical environment (climate, noise, pollution, traffic and attractions) scored a mean value of 2.92.

Data normality was tested using the Shapiro-Wilk and Kolmogorov-Smirnov tests (Table 2). In this analysis, a p-value >0.05 was expected for the null hypothesis to be maintained, as it would mean that data distribution was not different from a normal curve. However, it was observed that all the significance values of the Shapiro-Wilk test were below 0.05 and, in the Kolmogorov-Smirnov test, only the environment domain showed a distribution adherent to the normal curve (p-value=0.052). Thus, as they did not meet the normality assumption, non-parametric tests were used to compare the domains and to the groups established by the sample characterization data.

Table 2
Analysis of the Kolmogorov-Smirnov and Shapiro Wilk normality assumption of the domains that compose the WHOQOL-BREF. Brasilia, DF, Brazil. 2016. (n=123)

To verify if there was any difference among the domains, the Friedman ANOVA test was adopted, which confirmed the hypothesis (p-value <0.001). To verify how this difference occurred, the Post-hoc test was performed with a verification of each of the comparison pairs, which means that each of the dimensions was compared with the others, using p-value adjustment (dividing the value of 0.05 by the number of comparisons): (0.05/6=0.008) in order to avoid inflating the Type I error (Table 3).

Table 3
Post-hoc comparison among the WHOQOL-BREF domains. Brasilia, DF, Brazil. 2016. (n=123)

Table 3 shows that the environment domain was the worst evaluated. The attributed score was significantly lower than the physical (p-value < 0.001), psychological (p-value < 0.001) and social relations (p-value=0.007) domains. However, there was no statistically significant difference among the other dimensions (physical, psychological and social relations).

The correlation analysis was performed among the WHOQOL-BREF domains and the sociodemographic and clinical profile variables of the nurses. Ten different correlations were made (gender, age, marital status, academic level, time since graduation, place of work, length of service, other employment, presence of chronic disease and continuous use of medication) using the Mann-Whitney U test in the analyses with two independent samples and the Kruskal-Wallis test in the analyses with more than two independent samples. A significant correlation was observed (Table 4) only in the social relations (p=0.049) and environment (p=0.035) domains when comparing men and women, that is, when the independent variable was the participant's gender. There was no statistical significance in the other correlations.

With the data from Tables 4 and 5, it is possible to state that women (14.88; 8.00-20.00) better evaluated their social relations (p = 0.049) compared to men (13.78; 8.00-18.67). Similarly, women (14.17; 10.50-19.00) also had a better environment domain assessment (p=0.035) compared to men (13.07; 9.00-17.50).

showed that, of the 11,354 nurses in the DF, 85.6% are women.

The number of male nurses found at the SAMU DF (26.0%), however, was above the percentage of men in the profession registered at the COREN/DF (14.1%). This fact may be related to the growing number of men in the profession.33. Luchtemberg MN, Pires DEP. Nurses from the Mobile Emergency Service: profile and developed activities. Rev Bras Enferm [Internet]. 2016 [cited 2017 Jul 1];69(2):194-201. Available from: https://dx.doi.org/10.1590/0034-7167.2016690202i

A study2020. Mascarenhas CHM, Prado FO, Fernandes MH, Boery EN, Sena ELS. Qualidade de vida em trabalhadores da área de saúde: uma revisão sistemática. Espaço Saud [Internet]. 2013 [cited 2017 June 15]; 14(1):72-81. Available from: Available from: https://dx.doi.org/10.22421/1517-7130.2013v14n1/2p72

asserted the significant and tending entry of men in the nursing workforce in Brazil, representing 14.4% of all the registered professionals in Brazil.

The results regarding the participants' age are similar to those found in the literature,44. Silva AM, Guimarães LAM. Occupational stress and quality of life in nursing. Paidéia [Internet]. 2016 [cited 2017 June 13];26(63):63-70. Available from: https://dx.doi.org/10.1590/1982-43272663201608

Regarding the level of education, the research on the profile of the nurses from the SAMU in the state of Santa Catarina showed less significant data than those found in this study, since 3.2% of the evaluated population had a master's degree and no one had a doctorate.33. Luchtemberg MN, Pires DEP. Nurses from the Mobile Emergency Service: profile and developed activities. Rev Bras Enferm [Internet]. 2016 [cited 2017 Jul 1];69(2):194-201.

https://dx.doi.org/10.1590/0034-7167.201...

The participants' perception of quality of life and health showed positive values of 72.36% and 65.03%, respectively. This is contrary to the findings of a study99. Rosado IVM, Russo GHA, Maia EMC. Produzir saúde suscita adoecimento? As contradições do trabalho em hospitais públicos de urgência e emergência. Ciênc Saúde Coletiva [Internet]. 2015 [cited 2018 May 14]; 20(10):3021-32.

that evaluated the health and disease process of urgency and emergency public service professionals. This expressed the difficulty of nursing in dealing with work and the physical and psychological distress experienced in this environment. Of those evaluated, 24.2% were nurses and half of them, reflecting on the relation between work and health, reported that work weakens health. These nurses evaluated their QoL negatively and related this measurement to occupational stress.88. Azevedo BDS, Nery AA, Cardoso JP.

In the psychological domain, the negative feelings facet showed that 84.53% of the nurses reported episodes of bad mood, despair, anxiety and depression. These symptoms may be related to the work environment and to the activities performed in the SAMU66. Tavares TY, Santana JCB, Eloy MD, Oliveira RD, Paula RF.

. A study2525. Loro MM, Zeitoune RCG, Guido LA, Silveira CR, Silva RM. Revealing risk situations in the context of nursing work at urgency and emergency services. Esc Anna Nery [Internet]. 2016. [cited 2018 May 22];20(4):e20160086. Available from: https://dx.doi.org/10.5935/1414-8145.20160086
https://dx.doi.org/10.5935/1414-8145.201...
that reported on risk situations in the context of the SAMU showed that 92.9% of the nursing professionals investigated suffered some kind of psychological aggression, in contact with relatives of victims in imminent danger of death.

The environment domain was the worst evaluated, with a mean value of 13.88. The physical environment facet (climate, noise, pollution, traffic and attractions) accumulated the lowest mean value (2.92). A study,2626. Vitorino LM, Monteiro FP, Silva JV, Dias EM, Santos AEO. Qualidade de vida da equipe de enfermagem em unidades de urgência e emergência. Rev Ciênc Méd [Internet]. 2014 [cited 2018 Aug 10];23(2):83-9. Available from: Available from: https://dx.doi.org/10.24220/2318-0897v23n2a2527
https://dx.doi.org/10.24220/2318-0897v23...
using the WHOQOL-BREF, conducted with nurses in urgent and intensive care settings, showed a similar result: a mean value of 13.97, the lowest among the analyzed dimensions.

Another research2727. Souza EOR. Qualidade de vida dos profissionais de enfermagem que atuam em unidades pediátricas de hospitais escola do município de Belo Horizonte [tese]. Belo Horizonte, MG(BR): Universidade Federal de Minas Gerais, Escola de Enfermagem; 2017 that compared the QoL of nurses in different places of work and levels of care complexity in a university hospital, regarding urgencies, revealed similar values to this study in the environment dimension, with a mean value of 10.31. Comparing to the other sectors of the institution, intensive care unit and ward, with mean values of 10.47 and 10.44 respectively, this domain was also the worst evaluated. A survey2828. Queiroz DL, Souza JC. Quality of life and capacity for work of nurses. Psicol Inf [Internet]. 2012 [cited 2017 June 19];16(16):103-26. Available from: https://pepsic.bvsalud.org/pdf/psicoinfo/v16n16/v16n16a05.pdf
https://pepsic.bvsalud.org/pdf/psicoinfo...
conducted with nurses from the emergency department of a private hospital, showed the physical domain as worst evaluated, with a mean value of 12.00.

By correlating the sociodemographic and clinical variables with the WHOQOL-BREF domains, a statistical significance was obtained in relation to gender in the social relations and environment domains. The women rated these domains better when compared to the men. This is in line with a study that revealed a better mean value attributed by women in all domains of the WHOQOL-BREF evaluation.2828. Queiroz DL, Souza JC. Quality of life and capacity for work of nurses. Psicol Inf [Internet]. 2012 [cited 2017 June 19];16(16):103-26. Available from: https://pepsic.bvsalud.org/pdf/psicoinfo/v16n16/v16n16a05.pdf
https://pepsic.bvsalud.org/pdf/psicoinfo...
Regarding the social relations, the positive measurement may be related to the management, communication and conflict resolution skills necessarily developed by female nurses.2929. Araújo MP, Medeiros SM, Quental LLC. Interpersonal relations among nursing staff: fragilities and strengths. Rev Enferm UERJ [Internet]. 2016 [cited 2017 Aug 15]; 24(5):e7657. Available from: https://dx.doi.org/10.12957/reuerj.2016.7657
https://dx.doi.org/10.12957/reuerj.2016....

The use of a generic QoL assessment tool allowed us to know the multiple dimensions involved in the assessment and to verify positively and negatively evaluated facets. However, this methodology was unable to detect specific conditions, such as the influence of training and continuing education, as well as the adequacy or satisfaction with the career chosen as influencing nurses' QoL.

CONCLUSION

The facets of pain and discomfort, dependence on treatments and medications and physical environment (climate, noise, pollution, traffic and attractions) were negative influences on the QoL of the nurses from the SAMU/DF, as they had worse scores. These are linked to the social and working life and together can trigger negative feelings, which have a direct influence on the degree of satisfaction/dissatisfaction showed by nurses with their QoL.

The improvement of the QoL of these professionals can have a positive influence on the humanization process of care, as the well-being of the nurses is reflected in their way of caring. The participants need support to cope with the various situations that interfere with their QoL, especially those that are linked to the work process, and to the proximity to suffering and death. This need is evidenced by the presence of negative feelings that permeated the daily lives of the nurses from the SAMU/DF.

When considering the work environment of these professionals, with often inadequate physical space, service on public roads or at the patient's home, with insufficient resources, facing the crisis that affects the Unified Health System (Sistema Único de Saúde, SUS), with poor security and a retribution considered unsatisfactory by the category, it is possible to understand some of the reasons that justify the environment domain being the worst evaluated. There is a need for better management, structuring and adequacy plans for the insertion and working conditions of these workers.

The knowledge produced by this research may support the design of strategies that enable to reduce the difficulties related to life and work of the nurses from the SAMU. Actions in this direction may contribute to the improvement of health, well-being and QoL of the professionals and will have positive effects on the quality of the health care provided to the population.
