Level of anxiety symptoms and its associated factors among nurses working in emergency and intensive care unit at public hospitals in Addis Ababa, Ethiopia

Background Anxiety is a common phenomenon in some professions including medical emergency settings. Nurses deal with grief and other psychological disturbances when they lost clients due to death at clinical settings. Thus, the level of anxiety among nurses working at emergency and intensive care unit is expected to higher as a result of life threatening cases and frequent loss of clients at emergency settings. However, the burden of anxiety and its associated factors among nurses working in emergency clinical settings are not well addressed in Ethiopia. Methods An institutional based cross-sectional study design was conducted among 415 randomly selected nurses working at emergency and Intensive Care Unit at public hospitals in Addis Ababa. Data were collected using interviewer administered questioner. The Hamilton Anxiety Rating Scale was used to measure level of anxiety symptoms. The collected data were entered to a computer using Epi-Data Version 3.1 and exported to SPSS Version 20.0 for analysis. Binary logistic regression was used to identify factors associated with anxiety. Variables with P- Values of < 0.05 were considered as having statistically significant association with higher level of anxiety symptoms with 95 % confidence intervals. Results The result of this study shows that 19.8 % nurses working at emergency and intensive care unit had a higher level of anxiety symptoms [95 % CI (16.1 %- 23.6 %)]. Marital status{0.28:95 %CI(0.16-0.50)}, cigarette smoking{2.48:95 %CI(1.18-5.18)}, work overload {0.35:95 %CI(0.16,0.76)} and night duty shift{0.41:95 %CI(0.19-0.87)} were factors significantly associated with higher level of anxiety symptoms among nurses working at emergency medical settings. Conclusions Nurses working at emergency and intensive care unit showed higher level of anxiety symptoms than the general population and nurses working at other medical settings. Marital status, cigarette smoking, work overload and night duty shift had statistically significant association with higher anxiety symptoms among nurses working at emergency medical settings. This demonstrates a need for the implementation of counseling services regarding effective coping mechanisms and problem-solving strategies for nurses working at emergency medical settings.
