Background: Medical errors are the third leading cause of death in America. Over 10,000 medical errors occur daily, with an estimated financial impact of preventable mistakes is 20 billion dollars annually. Increasing the use of multifarious sophisticated medical technologies in the Intensive Care Unit (ICU) poses a risk of medical errors and unintentional harm to patients. However, limited empirical evidence exists regarding ICU nurses’ perspectives.

Purpose: This study aimed to elucidate ICU nurses’ perceptions of their use of complex medical devices.

Framework: The Conceptual Model for Technology, Nursing, and Patient Safety provide the framework for this study.

Sample: Using purposive, convenience, and snowball sampling, 260 ICU nurses throughout the United States participated in this study.

Methods: The study featured an online mixed methods descriptive exploratory research approach. The Hospital Survey on Patient Safety Culture (HSOPSC) survey, opened-ended questions, and demographic data were collected using RedCap©.

Data Analyses: Quantitative data were analyzed using the R (version 4.2.0) statistical package. A two-tailed Pearson’s correlation and linear regression models were used to test the hypothesis. The NVivo© for Mac 11.4.3 software was used to analyze the qualitative data.

Results: The results revealed a significant relationship between nurses’ safety perceptions and the years of experience, education, and medical device competency.

Conclusion: The findings inform medical device education standards, intervention research, and policy changes.
