Background and Goal of Study: Intensive care unit staff is a well known high risk contingent for developing burnout syndrome (BOS) due to chronic occupational stress exposure. Burnout is associated with lower work effectiveness, decreased job satisfaction and ultimately threatens the quality of care and safety of ICU patients. Age, standing and work regimens (day or night shifts) are among important factors potentially influencing the frequency and severity of BOS. We aimed at evaluation of these factors relationships with BOS in nurses of a 26 beds general ICU.

Materials and Methods: We prospectively evaluated 38 ICU nurses with the Maslach Burnout Inventory (MBI). MBI forms were filled on anonymous basis and surveyed by blinded investigator. Respondent's age, shift regimen (day time or night) as well as length of service in ICU were recorded in conjunction with MBI scores. Parameters were categorized into following groups: age - Gr. I: 21-30 (n=17); Gr. II: 31-40 (n=14) and Gr. III: 41-50 years (n=7); standing - 1-5 years (n=18), 6-10 years (n=12) and more than 10 (n=8) consecutive years of service in the same department; shift type - day time - 0 (n=10) and night -1 (n=28). Statistical analysis was performed by independent samples t-test and between subjects ANOVA with subsequent Post Hoc Tukey test. Values are expressed as means and standard deviations

Results and Discussion: BOS prevalence was 33.8 % when cut-off value of 60 points was applied. Average MBI score in total population was 64.7. We detected an association between increasing MBI scores and age: 61.6 (10.1), 61.8 (10.3) and 78.2 (10.8) for groups I, II, and III respectively with a statistically significant difference between Gr. I and Gr. III (p=0.003) and Gr. II and Gr. III. (p=0.004). There was no similar association between standing or shift subgroups and MBI points (p=0.68 and 0.83 respectively).

Conclusion(s): Our data demonstrated high prevalence of BOS among ICU nurses. From three parameters only increasing age significantly correlated with high MBI scores but we didn't detect similar relationships with regards to standing and work regimen. Limitations include small sample volume and difficulties with exclusion of other factors potentially influencing incidence and severity of BOS. We've planned future expanded studies highlighting interplay between multiple factors and their changes after organizational interventions.
