Measuring alarm fatigue in intensive care units: translation and validation of the Charité Alarm Fatigue Questionnaire: a multi-centre study.

Background: Alarm fatigue can negatively impact patient safety and quality of health care, particularly in Intensive Care Units (ICUs). The Charité Alarm Fatigue Questionnaire (CAFQa) is a German questionnaire measuring alarm fatigue in two scales (alarm stress and alarm coping) in nurses and physicians. Its hypothesized dimensionality has not been investigated in non-German-speaking countries.
