The impact of ERI, burnout, and caring for SARS patients on hospital nurses' self-reported compliance with infection control.

Siegrist's (1996) Effort-Reward Imbalance (ERI) Model provided the theoretical basis for this secondary data analysis that examines the relationship between nurses' ERI and their self-reported compliance with infection control, between ERI and burnout and nurses' compliance, and between nurses' experience in caring for SARS patients and their compliance with infection control. Data for this study came from a collaborative interdisciplinary study examining the barriers and facilitators to implementing protective measures against SARS and other existing and emerging infections among hospital nurses in Ontario and British Columbia. This is the first study to examine the relationship between ERI and compliance with infection control, as well as the impact of nurses' experience in caring for SARS patients on their compliance behaviour with infection control. Hierarchical multiple linear regression analyses revealed that ERI is a significant predictor of decreased compliance with infection control (beta = -.15, p < .05). While ERI was shown to be associated with burnout (beta = .60, p < .001), the combined effect of these two variables did not significantly improve the prediction of compliance behaviour (beta = -.03, p = .63). Nurses who reported having directly cared for SARS patients were found to have increased compliance with infection control (beta = .15, p < .001) after controlling for demographic and work environment factors. These findings highlight how nurses' adverse workplace environments can affect their work and health and thus, can be used by nursing and hospital administrators to help develop interventions to lower occupational stress and improve health in the workplace.
