A National Survey of Stress and Burnout in Critical Care Nurses: A Prepandemic Study

Critical care nurses (CCNs) experience a higher level of stress and burnout than nurses in other specialties. Approximately 50% of CCNs are mildly stressed, and almost 20% are moderately stressed. Prolonged periods of stress can lead to burnout, which has been shown to have deleterious effects on quality and patient safety.

The purpose of this study is to determine the prevalence of burnout among a national sample of CCNs and the association with environmental factors.

A national survey of CCNs working in the United States was implemented using an exploratory descriptive design. The anonymous survey was developed iteratively according to best practices of survey design. The survey included the Perceived Stress Scale and the Copenhagen Burnout Inventory tool. Pretesting and pilot testing were conducted with CCN specialists, and the survey was revised based on their feedback. An anonymous link was distributed to respondents using convenience sampling through social media and further disseminated via snowball sampling.

Two hundred seventy nurses responded to the survey. The mean (SD) Perceived Stress Scale score in the study population was 18.5 (6.4), indicating moderate stress. The mean (SD) Copenhagen Burnout Inventory score was 61.9 (16.5), indicating moderate burnout. Our study found that the overall health of the work environment was one of the most important factors associated with both stress and burnout.

This study has demonstrated the relationship between the health of the work environment and burnout among CCNs. It is imperative that health care organizations evaluate and implement strategies to optimize the health of the work environment to mitigate burnout and its negative sequelae on the nurse, patient, and system.
