Abstract
Background: Occupational stress is commonly observed among staff in intensive care units (ICUs). Sociodemographic, organizational, and job-related factors may lead to burnout among ICU health workers. In addition, these factors could modify the balance between efforts done and rewards perceived by workers; consequently, this imbalance could increase levels of emotional exhaustion and depersonalization and decrease a sense of personal accomplishment.
Objective: The purpose of this study was to analyze the relationship between effort-reward imbalance and burnout dimensions (emotional exhaustion, depersonalization, and personal accomplishment) among ICU nursing staff in a university hospital in Santiago, Chile.
Methods: A convenience sample of 36 registered nurses and 46 nurse aides answered the Maslach Burnout Inventory and Effort-Reward Imbalance Questionnaire and provided sociodemographic and work-related data.
Results: Age and effort-reward imbalance were significantly associated with emotional exhaustion in both registered nurses and nurse aides; age was negatively correlated with emotional exhaustion, whereas effort-reward imbalance was positively correlated. Age was negatively associated with depersonalization. None of the predictors were associated with personal accomplishment.
Discussion: This study adds valuable information about relationships of sociodemographic factors and effort-reward imbalance and their impact on dimensions of burnout, particularly on emotional exhaustion.
