One of the main objectives for every organization is to increase its productivity. To reach this goal, there is no option except to resort to a systematic, local and applicable perspective (
1). Productivity is a general and comprehensive concept, but increasing it is considered by politicians, economists and governing bodies as a necessity in order to promote; quality of life, improve welfare, and benefit society (
2). At national and international levels, competition is only possible through increased productivity and this in turn increases society’s standards of living. However, as a result, people insist on better services from governmental organizations. In response to these demands higher levels of achievements need to be reached, but often with fewer resources. By increasing productivity, governmental organizations are able to improve their ability to deliver quality social services and develop more effective and efficient plans (
2). In fact, the creation of productivity cultures creates better use of physical and spiritual facilities in organizations (
3). In this regard, hospitals are one of the most important organizations, as they deliver health-care services and play an important role in the; preservation, return and promotion of their clients’ physical and psychological health (
1). Increasing productivity, prudent use of limited resources and exact evaluation of the quality of services required to fulfill, protect and promote patients' health in hospitals, are important missions of medical centers (
4). Researchers believe that attaining ongoing productivity, creativity, innovation and suitable life quality, is dependent on committed, intelligent, effective and efficient human resources and management (
5). Effective human resource management is the main factor for the continuity, success and goal attainment in organizations. In this regard, the productivity of nursing staff is very important, because nurses carry the main responsibility for care quality and health promotion of their clients (
6). Nurses represent the largest faction of healthcare professionals, with more than 2.6 million nurses in the United States (US) alone, and they are at the frontline for direct patient care in hospitals (
7). In the US between 2003 and 2011, the number of employed registered nurses (RNs) increased from 2,449,000 to 2,724,570, an increase of 10.1%, and it is predicted that the employment of RNs will grow to 26% from 2010 to 2020, faster than the average for all other occupations (
8). In 2008, approximately 90,000 nurses were working in Iran’s health-care system (
9). Nurse groups influence the productivity and progress of organizations more than any other group. Of course, no health-care organization can survive without an efficient nursing unit (
6,
10). Furthermore, the current auditing processes which insists on cost-effective nursing care with the same or fewer numbers of personnel, in addition to progress in productivity, is considered to be the basic responsibility of nursing managers (
10). Researchers believe that if the nursing profession desires to survive financially and professionally; finding strategies which state the productivity and related issues in an organizational context, are essential (
10). Studies indicate that decreasing productivity results in; losses of income, inflation, unemployment, lower life quality, and decreases in social safety. Whereas, increasing productivity creates the best use of an organization's physical and moral resources, and as a result it makes the best of the organization's potential abilities, talents and facilities, which allows it to; flourish and increase wages, reduce the price of products and services, attain higher living standards, create greater benefits, increase economic development, ensure its survival and enhance organizational accomplishments (
11). Lack of a productive, healthy work environment has been related to nursing shortages, poor quality of working life, job dissatisfaction, low productivity, poor quality and unsafe patient care practices (
12). In addition, recent researches have highlighted the increasing growth of burnout and psychological disorders, especially depression and anxiety, in health-care staff like nurses (
13-
22). Studies have shown that health-care staff face more issues when compared to other types of employees, which results in declining job function and creates psycho-social problems. As a result, burnout due to confronting stresses such as; the death of a patient, caring for patients with complicated care needs, intrapersonal problems, little social support, high work pressures, absence of job security, low salary and privileges, dealing with large numbers of patients each day, making decisions in emergency situations based on insufficient information and being responsible for the outcomes of those decisions, mental pressure for avoiding mistakes, confronting the threat of violence at work, and working night shifts, are common experiences (
17,
22,
23).
Burnout is one of the main professional issues which imposes noticeable expense on organizations (
22). Evidence has shown that burnout is strongly linked to nursing turnover, which has led to the current nursing shortage. This shortage remains ongoing and estimates for the shortage by the year 2020 range from 340,000 to 1 million. Furthermore, inadequate nursing levels caused by excessive turnover have been significantly associated with nursing errors and poorer patient outcomes (
7). According to Aiken et al. 29% of nurses in the US state of California experienced high burnout, compared with 34% of nurses in New Jersey and 36% of nurses in Pennsylvania (
8). Also, burnout is a significant contributor to job satisfaction which needs to be decreased in order to improve job satisfaction (
16). Studies have revealed that one in five nurses leave their job due to dissatisfaction, notably burnout and stress (
15).
Moreover, studies have indicated that decreasing energy levels and work efficiency (
20,
21), increasing absences at work, opting to leave the profession (
2,
13,
20-
25), continuous delays(
13), increasing health expenses, behavior and physical changes like feeling tired, headaches, gastro-intestinal problems and sleep disorders (
13), addiction (
20), anxiety and depression, and intrapersonal conflict (
23,
24), can cause burnout in health-care staff such as nurses. Thus resulting in decreases in the quantity (
26) and quality of caring for patients and consequently patients' dissatisfaction (
13,
14,
20-
22,
25). Evidences have indicated that the diagnosis and prevention of burnout can play an active role in promoting an individual's psychological health and improve their quality of services (
20); therefore, social support, managerial and occupational systems can decrease burnout and improve the psychological health of staff by reducing occupational tensions (
23).
In all probability, burnout is one of the most important and effective factors on the productivity of nurses (
6). Some studies have indicated that emotional exhaustion (EE) and depersonalization (DP) had a significant negative relationship with nurses’ productivity. In addition, there was a significant positive relationship between personal accomplishment (PA) and productivity in nurses (
27). Some studies have reported that job stress is associated with decreased work productivity (
18). While other evidence has shown that lack of human resources results in the creation of; severe stress, burnout, reduction of productivity, lower quality of patient care and finally in patient dissatisfaction (
9).
In Iran, the productivity of nurses, which consists of the majority of health care staff, has been one of the major issues for health system managers in recent years and in this regard, they have appealed to the government to take certain actions such as privatization (
28). Numerous researches have also reviewed nurses’ burnout levels (
17,
27,
29-
36). If the relationship between burnout and productivity becomes apparent, managers can then provide conditions for the nurses to be more productive. Despite the studies which have been performed on productivity and burnout of health care staff, a range of different results have been reported.
