The study assessed the level of alarm fatigue in cardiovascular intensive care unit nurses. It included 78 nurses from two hospitals, including 41 in the coronary intensive care unit and 37 in the cardiovascular surgery unit. Quantitative data were provided by 60 nurses through a questionnaire and an employment form, qualitative data were obtained through semi-structured interviews until data saturation was achieved. Nurses experience a moderate level of alarm fatigue, which is related to alarm discomfort. Qualitative analysis revealed five themes: the organizational dimension of alarms, nurses' awareness of alarms, causes of alarms, effects on nurses, and effects on patient awareness. Alarm fatigue is multidimensional and involves nurses, patients, institutions and other entities. The authors recommend future studies considering organizational culture and dynamics, including comprehensive training of nurses on alarm management.[1][5]
