Systemic Identification of Factors Affecting Emergency Department Nurses’ Fatigue in TUMS Hospitals and Developing a Holistic Model

Compared to other hospital departments, emergency department (ED) nurses experience higher levels of occupational fatigue. However, despite the importance of fatigue in EDs, limited studies have investigated the issue. Therefore, the present study aimed to identify factors affecting ED nurses’ fatigue with a systemic approach and provide a comprehensive model of fatigue.

The present study was the first phase of a mixed-methods study with an exploratory sequential design that was conducted qualitatively. Data was collected using a semi-structured interview technique among ED nurses in TUMS hospitals in Tehran. The data was analyzed with a systematic approach and qualitative content analysis method. To check the credibility and trustworthiness of the study results, Goba and Lincoln criteria, including transferability, peer review, and member check, were used.

Extensive factors were identified in the four levels of nurses’ work system, including individual factors, work unit, organization, and extra-hospital factors that could facilitate or prevent nurse fatigue. Specifically, the categories that were mentioned the most by the nurses were aggression and conflict with visitors, ED workload, understaffing, crowding and noise, obligatory overtime, acknowledgement, visitor’s expectations, reporting (paperwork), and clients’ distrust of nurses. Finally, based on the qualitative results, a conceptual model of factors affecting occupational fatigue of ED nurses in Tehran was presented.

Traditionally, fatigue management programs in hospitals only consider issues related to work shifts and sleep hygiene. However, the results of the present study revealed other fatiguing factors in the work system of ED nurses. These findings can help health system decision makers and HFE experts in designing effective fatigue risk management systems in Iranian hospitals, especially in emergency departments.
