The present study aimed to identify barriers to provide high-quality nursing care in ICU. The obtained codes were categorized into three main categories, as follows: "Barriers to provide care", "motivational barriers", and "managerial barriers". The findings indicated these factors influence the quality of care in ICU.
"Barriers to providing care" were identified as the main category with the following sub-themes: high workload, not considering the educational needs, not considering the work standards, out of duty cares, and bad structure of the ward. There are other studies which showed that barriers to care play an important role in providing high-quality care. This finding is consistent with the study of Nobahar et al. (2014) which showed that the structure of the ward and its facilities affect the quality of care (
14). There are quantitative studies that showed that the equipment of the ward plays an important role in the quality of patient care. A study conducted in the ICUs of the Mazandaran province reported that ICU nurses had a high workload (
15). A review study reported that ICU nurses in various countries experience different workloads (
6). In this regard, Om Hashem et al. (2013) argued that to maintain ICU nurses their workload should be reduced (
16). Fallahian et al. (2013) showed that the ICU was not built according to the standards and suggested that improving structural standards guarantees the quality and optimal performance in the ward (
17). The observed difference in the workload of ICU nurses can be attributed to the number of staff, patients’ profile, and severity of diseases as well as laws and regulations governing the provision of medical services. In line with the lack of attention to educational needs, Alaei et al. (2012) showed that training the staff of ICU by their clinical supervisors positively affects the performance of nurses (
10). Sadeghian et al. (2017), in a study on improving the quality of care in hemodialysis wards, showed that in addition to the knowledge and skills of nurses, they should also be trained in the emotional dimension, which helps the nurses to provide high-quality care (
18). Ahmadi et al. (2011) reported that the availability of resources is a sufficient and appropriate feature of special wards. Therefore, lack of equipment or their breakdown will reduce the quality of care. Lack of equipment and facilities increases the workload of nurses and negatively affects them, which causes waste of time and energy that, in turn, leads to fatigue and lower performance. Therefore, the sufficiency of resources can reduce the work problems of nurses and improve the quality of nursing services (
19). In the present study, one of the reasons for the low quality of care was doing tasks that are not related to the nursing staff, which causes increased work pressure. There are arguments about the negative association between the number of staff and the workload of the staff, which in turn affects the quality of the provided car (
20). It seems in cases with a high number of patients and a low number of nursing staff, the staff may focus only on the main tasks, instead of tasks that should be done by others. It worth noting that in some texts, ineffective care has been referred to as pointless care (
21). In fact, it can be inferred that barriers to care lead to poor care.
Motivational barriers were another category of the present study with the following sub-themes: "lack of individual motivation", "lack of organizational motivation", and "interference of individual and organizational motivation". In a qualitative study that investigated nurses' motivational factors, individual and organizational factors such as encouragement, interpersonal respect, meeting expectations, and consultation were identified as influential and promoting motivational factors in how nurses work together (
22). As the findings of several quantitative and qualitative studies show, motivation influences how individuals perform their tasks and work with other nurses; Therefore, if individual and intra-organizational motivational factors are not considered, they can be considered as a barrier to good performance and, of course, the quality of optimal care.
Managerial barriers was another extracted them with the following sub-themes: "Unsupported Rules", "Welfare Disorder", "Maintaining Position", and "Dysfunctional Physician-Nurse Communication". Rules without work support, work inconsistency in the ward, keeping the position, and inefficient communications between nurses and physicians. In a quantitative study, managerial barriers reported by nurses included the shortage of human resources, lack of financial resources, and inadequacy of equipment (
23). Another qualitative study mentioned the behavior of nursing managers as well as some characteristics of nursing managers, including lack of support from staff and disregard for nurses' opinions, dictatorship and obedience, trying to maintain position, discrimination, and insignificance, as the barriers to productivity. Organizing and guiding health staff were among the most important managerial barriers (
24). Some of these barriers, such as maintaining the position, are also found in the present study. In the sub-category of dysfunctional communication between physician and nurse, which was in line with the study of Shukri et al. (2013) in which the study of nurses reported that their professional relationship with physicians is moderate and the most important factor in disrupting the professional relationship The nurse did not seek medical advice from the patient-nurse in performing medical procedures, while in the same study, the physicians believed that they had a good relationship with the nurses (
25). A qualitative study on nurses' professional communication experiences has investigated such communications in the context of physician-patient communication deficit and reported that nurses fill the gap between the doctor and the patient (
26).
In this regard, a qualitative study on the quality of care provided by ICU nurses reported that "adequate and efficient human resources", "human communication", "organizing the performance of the nurse", and "optimal environment, tools, equipment, and appropriate facilities are essential for providing high-quality care (
14). Also, a study aimed to determine factors that affect the communication between nursing managers and nurses, from the perspective of nurses, reported that human, organizational, and communication-related factors are effective in explaining the communication between nursing managers and nurses. Factors that influence the relationship between nursing managers and nursing staff play a role in improving the quality of nursing care (
27).
5.2. Conclusion
This study described the barriers to providing high-quality care from the perspective of ICU nurses. Based on the findings, to improve the quality of care, barriers related to providing care, motivations, and management should be addressed. The findings provided an overview of the barriers to quality care and showed that to provide quality care, all barriers should be considered, regardless of all aforementioned issues, improving quality care would be an important challenge. Finally, it can be argued that effective nursing management is an important step towards removing barriers to providing care, motivation, and management. Administrators of the nursing staff should change the management system and ultimately improve the quality of care using the findings of the present study.
