Abstract

Reducing nurses’ autonomy can impair their decision-making and ability for appropriate interventions. Lowered independence hinders ethical reasoning, which may lead to moral distress. This descriptive correlation study investigates the relationship between professional independence and moral distress in 173 nurses working in emergency departments in Tabriz, Iran. Data were collected using questionnaires designed to assess professional autonomy and moral distress and analysed using descriptive and inferential statistics via the SPSS 13 software. The level of professional autonomy among emergency nurses was low (83.2±16.9), and moral distress, moderate (7.43±3.52). A statistically significant negative relationship was reported between professional independence and the frequency of moral distress (p=0.018). Bivariate analysis related professional autonomy with the frequency and intensity of moral distress. Multiple regression analysis showed that age significantly predicted moral distress (frequency, intensity, and total scores). Lack of autonomy hinders nurses from functioning effectively and efficiently in practice and even can lead to moral distress. Increasing professional independence and the use of experienced nurses as mentors in emergency settings to support younger nurses can help with the reduction of moral distress.

Introduction

Autonomy is an important element of professional identity and quality of care in clinical practice. Professional independence in nursing has been defined as nurses’ ability to make independent decisions based on sufficient knowledge, clinical expertise, and evidence-based practice (1). Reduction of nurses’ autonomy can hinder nurses from making decisions, which can lead to moral distress (2). Invasive procedures, patients’ health conditions, resuscitation practice, and working with incompetent staff and policies that are in conflict with patients’ needs are challenges that nurses face in clinical practice (3).

Moral distress is defined as one type of discomfort that affects mind, body, and interpersonal relationships in the workplace. This is a result of conflict between what a person believes and how the person acts (4). In Jampton’s view, moral tension arises when a person knows what the right thing to do is but is prevented from, and feels incapable of, doing it (5). A practical definition may be that moral distress is a painful feeling occurring when nurses are confronted with an action that is morally appropriate, but cannot do it because of institutional policies. Studies have shown that 80% of nurses experience moderate to high levels of moral distress in their working environments (1, 6). In a study by Corley, 15% of nurses left the profession because of moral tensions (6).

Common causes of moral distress among nurses are work pressure, high expectations of patients and their families, unnecessary examinations for patients, and the need for decision making about the final stages of life (1, 7). Moral tensions can have some adverse consequences for nurses and patients, including the loss of self-esteem, disappointment in professional life, reduced job satisfaction, burnout, and even giving up their career in nursing (8, 9).

Papathanassoglou et al (2) showed a converse relationship between the level of professional independence and moral distress among nurses working in intensive care units. Ando and Kawano (10) reported that moral distress among psychiatric nurses was conversely related to their job satisfaction. Jacobson et al, in a study on the effects on moral/emotional traits of workplace bullying in Master of Business Administration (MBA) students, found that moral/emotional traits could be useful during the staff’s selection process (11). Additionally, age (3) and work experience (12) are other factors influencing emotional distress.

There is need for a professional method of dealing with professional dilemmas (13). Previous studies have focused on moral distress among nurses working in intensive care units, but we have surveyed the moral distress among nurses in emergency departments. Emergency nurses are exposed to more psychological and moral stresses due to the stressful atmosphere in the emergency room. The direct exposure of staff to patients and their relatives and patients’ acute problems contribute to stressful situations (14). However, there has been little evidence of the relationship between nurses’ professional independence and moral distress in emergency nurses.

We hypothesised that professional independence has a relationship with moral distress among emergency nurses. This study was conducted to examine the relationship between professional independence and moral distress among nurses working in emergency departments.

Methods

Participants and setting

Astbury et al (15) declared that quantitative studies can measure and analyse the causal relationship between moral distress and associated variables. This descriptive correlation study was conducted in the emergency departments at five educational public hospitals in an urban area of Iran. The sample size was determined based on the findings of the Papathanassoglou study (2), the correlation between professional independence and moral distress (-0.21), with 95% confidence interval, 80% power and the bilateral test using the G power software version 3.0.10. Therefore, the samples estimated 178 individuals. However, considering 5% drop out of samples, the final sample size was determined as 187 nurses. Therefore, 187 nurses working in emergency departments were selected using stratified sampling. The number of nurses from each hospital was selected proportional to the number of nurses working in the emergency department in each of the 5 hospitals. Nine subjects refused to continue the study, and five questionnaires were not completely filled out. Therefore, data from 173 nurses were considered for analysis.

Inclusion criteria were: 1) having a Bachelor’s degree or higher qualification in nursing; 2) at least one year’s experience in the emergency room; and 3) having attained the age of 22 years or above. Those nurses who had changed their workplace within the past six months were excluded from the study.

Measurement tools

The demographic data form consisted of questions on age, gender, marital status, work experience in the emergency room and income status. The original professional autonomy questionnaire which has been developed by Schutzenhofer to measure nurses’ professional autonomy (16) was used in this study. It contained 30 items and used a four-point Likert scale of 1 to 5. Total scores ranged from 30 to 150. In this study for better presentation, we considered scores between 30-70 as low independence, 71-110 as moderate independence, and above 110 as higher independence. Its reliability, using the Cronbach’s alpha coefficient, was reported as 0.94.

Moral distress was measured using the Moral Distress Scale-Revised (MDS-R), which was revised by Ann Hamric based on Corley’s original 38 item scale (17). The revised version had 21 items with a five-point Likert scale that measured the frequency and intensity of nurses’ ethical tension (17). Higher scores indicated increased frequency and intensity of moral distress. In this study, we considered scores between 0 and 42 to indicate low frequency or intensity of moral tension; 43-84 moderate moral tension; and 85-126 higher intensity or frequency of moral distress. The reliability of the MDS-R using the calculation of the Cronbach’s alpha coefficient was 0.88 (14). In the present study, the internal consistency was reported as 0.81.

The validity of these questionnaires was confirmed by ten faculty members.

Ethical considerations

Prior to data collection, the aim and method of the study were explained to the participating nurses and informed consent was given by them. The ethics committee of the Tabriz University of Medical Sciences approved the study via approval number 1036514, dated August 31, 2017. Participation was optional, and the participants were assured that no identifying material would be collected from them.

Data collection and analysis

From April 2017 to June 2017, the questionnaires were given to the emergency nurses in different work shifts and they were asked to fill them out via the self-report method. Data analysis was performed using the SPSS 13 software. Demographic data, professional autonomy and moral distress were analysed through descriptive statistics (frequency, percentage, mean, and standard deviation). After evaluating and confirming the normality of data, correlations between professional autonomy and moral distress and demographic characters were analysed using the t-test, ANOVA, and Pearson correlation tests. The linear multivariate regression model was used to predict moral distress scores from contextual factors as autonomy scores were considered an independent variable.

Results

A total of 173 out of 187 distributed questionnaires were completed. Results are presented as per the different subscales.

Demographic information of subjects
The number of male nurses slightly exceeded that of female nurses (52.6% and 47.4%, respectively). Most of the subjects were under 30 years, married, and had experience of 1 to 5 years in emergency nursing. Most nurses indicated that their expenditure exceeded their income (Table 1).

Professional autonomy
The mean professional autonomy score of subjects was 83.20±16.89, which indicates a low level of autonomy. Professional autonomy scores vis-a-vis demographic are shown in Table 1. Data analysis using independent t-test and ANOVA showed no significant differences (p>o.o5) in autonomy scores based on demographic characters (Table 1).

Moral distress
The frequency and intensity of moral distress of emergency nurses were at moderate levels. The moral distress of participants based on demographic factors is shown in Table 1. Data analysis using independent t-test and ANOVA showed significant differences between frequency and intensity of moral distress based on age (p=0.001) and work experience (p <0.001) (Table 1).

Relationship between professional autonomy and moral distress
Bivariate analysis by the Pearson correlation coefficient between professional autonomy and moral distress is shown in Table 2. Professional autonomy had a significant relationship with frequency and intensity of moral distress (p <0.01).

Three multiple regression analyses were run to predict moral distress scores (frequency and intensity) by sex, age, years of experience in emergency nursing, and autonomy scores.

In the first model for prediction of independent variables, autonomy and age significantly predicted moral distress frequency by F (4,168) = 13.525, p <0.001, R2=0 .244. The proportion of variance in frequency of moral distress by these two predictors was 24.4 %. Unstandardised coefficient for autonomy was -0.226 (Table 3).

In the second model for prediction of independent variables, age significantly predicted the intensity of moral distress by F (4,168) = 4.062, p = 0.004, R2 = 0.08. The proportion of variance in moral distress intensity by age was 8%. Unstandardised coefficient for autonomy was -0.112. This means that for each one-point score increase in autonomy, there is a 0.112 score decrease in intensity of moral distress, all other independent variables considered constant (Table 4).

Work experience in emergency nursing -0.988 1.143 -0.071 0.388 -3.245 1.268

In the third model, for prediction of total moral distress from independent variables, age and autonomy significantly predicted it at F (4,168) = 8.911, p <0.001, R2=0 .175. The proportion of variance in total moral distress was 17.5% and unstandardised coefficient for autonomy was -0.333. This means that for each one-point score increase in autonomy, there is a 0.333 decrease in total moral distress, all other independent variables considered constant (Table 5). Based on the study hypothesis, professional autonomy had a significant negative correlation with moral distress.

Discussion

The findings of this study provided an initial figure of emergency nurses’ autonomy and their moral distress. The mean of professional autonomy scores was low. The findings of the present study are in line with those in the study by Sarkoohijabalbarezi et al. (18). All the nurses in this study worked in emergency wards. However, studies on nurses working in intensive care settings and clinical nurses documented a higher level of nurse autonomy (2, 10, 19, 20, 21).

Limiting the autonomy of nurses restricts their ability to decide and act in situations where quick and critical decisions are needed. When hospitals have no specific policies for addressing incidents of moral tension and conflict, it becomes difficult for nurses to make appropriate decisions and increases their distress. According to Mirsaidi et al, the low level of professional independence among nurses in Iran is related to obedience to doctors (22). The three most important factors that reduce nurses’ autonomy are autocratic management (unnecessary interference), pressure on nurses to implement physicians’ orders, and workload (23). The intensity and frequency of emotional distress among nurses in emergency settings was at a moderate level. This is in line with the results of other studies (3, 14, 24) on moral distress in nurses. Alternatively, the results of the Papathanassoglou (2) study showed a low level of moral distress among nurses in intensive care units. Such a discrepancy in various studies can be attributed to different environments, work conditions, and unequal situations. It may be considered that nurses worry about professional errors. The more the tensions in the organisational environment, the higher the tensions perceived by staff, and consequently, the more the moral tensions.

Age had a negative and significant correlation with the frequency and intensity of moral distress. Borhani et al (4) showed that age and work experience had negative relationships with moral distress. Nurses use their own biological and psychological capacities to deal with moral distress. When nurses experience stress, they are more likely to quit their jobs. Some may even be pushed to give up nursing (25).

Nurses experience moral stress when they want to make ethical decisions in special situations. However, organisational barriers—such as the lack of adequate time, lack of supportive authority, physicians’ superior authority, and policies and organisational rules—make it difficult for them to do the right thing, which creates moral distress among nurses.

There was a significant negative correlation between professional authority and frequency of moral distress. In other words, the greater the professional independence of nurses, the less moral tension they faced in emergency settings. These findings are in line with those of Karanikola et al in their study in intensive care units (20). Ameri et al (26) showed that professional independence of oncology nurses is one of the most important factors that reduced nurses’ moral distress. Sarkoohijabalbarezi et al in a study in paediatric intensive care units found a positive correlation between nurses’ professional autonomy and moral distress (18). They showed that increased professional autonomy without adequate support from physicians and relevant authorities was responsible for the positive relationship between professional autonomy and moral distress (18). Studies have shown that when nurses encounter the doctor-centred atmosphere of hospitals, it inhibits clinical decision-making by nurses, and requires absolute obedience to physicians’ orders. So, nurses’ lack of authority could lead to moral disturbances (20, 22). In this regard, Papathanassoglou et al showed collaboration scores were positively associated with autonomy scores. Lower levels of autonomy were associated with lower perceived nurse-physician collaboration (2). So, effective nurse-physician collaboration is imperative.

Limitations

This study was conducted on Iranian emergency nurses working in university hospitals. The level of nurses’ authority and moral distress may be different in other departments and hospitals. While this study included nurses working in all areas—triage, resuscitation and outpatient care—each area should be studied in detail.

Conclusions

A negative relationship was found between professional autonomy and moral distress indicating more emotional distress when nurses’ professional autonomy is compromised in emergency departments. When nurses are allowed to have greater independence to make decisions, the frequency and intensity of emotional distress is reduced. Therefore, it is recommended that support and interpersonal cooperation by nurse managers be increased and that experienced nurses should act as mentors to support younger nurses in emergency settings in order to reduce their moral distress.
