[Anxiety and stress in the nursing staff. A comparative study between intensive care and general wards]

We studied a population of 463 nurses working in intensive care units--ICUs--(distributed in 51 italian hospitals), and 216 nurses working in general medicine units (distributed in 17 italian hospitals). They we asked to fill in a form including: 1) general data and his/her work environment, and 2) some standardized scales (HAD A and D, STAI Y-1 and Y-2, MBI) for estimation of anxiety, depression and "burnout" syndrome. We used also the "P questions", evaluating the different situations of work environment causing anxiety. The aims of the study were to evaluate the effectiveness of different scales and the influence of general medicine and intensive care environment on psychological features. Among different scales estimating anxiety, the STAI Y-2, valuing a chronic anxiety status, results to be efficient, beside the already tested HAD A. The intensive care environment did not seem to be more stressful for nurses staff rather than general medicine units. Furthermore, nurses operating in general medicine units have a major tendency to depression; their work environment seems to favour the development of anxiety. Finally, it results that general medicine units cause a more severe "burnout" syndrome in their nurses staff rather than ICUs.
