Within health care, incorrect assessment or a stressful situation with a fraction of a second's inattention can lead to devastating consequences for the individual patient. Medical errors also contribute to higher costs for society in the form of extended treatment, sick-leave and the loss of income (Bogner, 1994). In addition to the suffering incurred by the individual patient and his/her loved ones, the medical error also involves mental strain, and sometimes social trauma, on the part of the personnel involved in the event (Wu et al, 1991; Christensen et al, 1992; Bark et al, 1997). According to a study from the Swedish National Institute for Working Life, these concerns constitute a greater stress factor than to traditional work environment problems (Sundström-Frisk, 1994). Consequently, these issues related to improving safety within the health care sector are also significant from the work environment perspective.
