Che stress di lavoro
Prehospital emergency medicine operators work in conditions of prolonged stress . It is believed that heart rate
variation can be used to predict behavioral responses to stress [2,3]. Stress affects how the individual perceives the
situation and their ability to deal with it [4,5].
Materials and methods
The population analysed (6 total operators) included nurses and doctors of the Vicenza Ambulance Control Centre. The
personnel was divided into a group of 3 experts (Exp) with more than 2 years of experience and 3 non-experts (NoExp).
The analysed operators wore the HealBe GoBe2 smartwatch during each mission (64 total missions with yellow and red
codes). The HealBe GoBe2 smartwatch records the heart rate (HR) every 5 minutes, before and after the alarm, on
scene and returning to the Control Centre.
After each mission, the operators filled out the questionnaire on the PainZero app regarding their state of mind: cheerful,
insecure, relaxed, annoyed, satisfied, alone, anxious, down and guilty. For each question they established a score from 1
(not at all) to 7 (a lot).
The repeated measure ANOVA showed “time” and “group” significant effects (Table 1) with the NoExp group having
greater heart rate throughout the assessment. Moreover, the HR on scene was significantly greater compare with the
other assessment timings.
A daily average of the feelings expressed on the PainZero app by the operators was performed and the between group
analysis was performed using the Mann-Whithey test. The Radar graph (Figure 1) shows that experts (Exp) feel more
satisfied and happier during their shift. Inversely, non-experts (NoExp) feel more down, insecure, anxious and alone after
a rescue mission.
Healthcare workers with more experience on scene have significantly lower heart rates than non-experts. Experienced
operators feel happier and more satisfied than non-experienced operators after a rescue mission.
The study is continuing by icreasing the sample and adding data regarding to the quality of sleep under stress and
