Longitudinal Evaluation of Implementation of AACN's Healthy Work Environment Framework in an Intensive Care Unit

Bedside nurse turnover in the United States is 22.5%, representing a national challenge that has been attributed to poor work environments. Poor work environments result in decreased nurse satisfaction and retention as well as poor patient outcomes. Healthy work environments have the opposite effects.

To evaluate the impact of implementation of the American Association of Critical-Care Nurses (AACN) healthy work environment framework in an intensive care unit on work environment scores, turnover, and tenure during a 6-year period.

A prospective, longitudinal design was used to evaluate implementation of the healthy work environment framework in an intensive care unit in a large academic medical facility. Interventions for each of the 6 healthy work environment standards were carried out. The AACN Healthy Work Environment Assessment Tool was used to measure each standard in 2017, 2019, 2021, and 2023.

No statistically significant differences were found between cohorts. The score for each healthy work environment standard and the overall score increased significantly from 2017 to 2023. Nurse turnover increased during the COVID-19 pandemic but restabilized within 2 years.

Findings from this study suggest that targeted interventions addressing the healthy work environment standards are associated with improved staff satisfaction and reduced turnover. Furthermore, the findings highlight the value of the healthy work environment framework in improving nurse retention.
