Description

This is the dataset that we used for evaluating the construct validity of the Charité Alarm Fatigue Questionnaire (CAFQa) in a forthcoming publication. All items were answered on a 5-point Likert scale and were scored by us as follows: -2/“I do not agree at all”, -1/“I do not agree”, 0/“I agree in part”, 1/“I agree”, 2/"I very much agree".

Variable names and their corresponding item. Items marked with a were reversely scored.
Variable Name CAFQa Item
procedural_instruction In my ward, procedural instruction on how to deal with alarms is regularly updated and shared with all staff.a
respond_quickly Responsible personnel respond quickly and appropriately to alarms.a
motivation_decrease With too many alarms on my ward, my work performance, and motivation decrease.
physical_symptoms Too many alarms trigger physical symptoms for me, e.g., nervousness, headaches, and sleep disturbances.
ward_floor The acoustic and visual monitor alarms used on my ward floor and in my nurse station allow me to assign the patient, the device, and the situation clearly.a
reduce_concentration Alarms reduce my concentration and attention.
alarm_limits Alarm limits are regularly adjusted based on patients' clinical pictures (e.g., blood pressure limits for conditions after bypass surgery).a
interrupt_workflow My or neighboring patients' alarms or crisis alarms frequently interrupt my workflow.
alarms_confuse There are situations when alarms confuse me.
