Workplace access, burnout, and prescription drug misuse among Korean hospital nurses: a cross-sectional study

Background Prescription drug misuse has been identified as a global issue of concern. Nurses' prescription drug misuse is linked to personal health problems and impaired nursing care. This study explored the level of South Korean hospital nurses' prescription drug misuse and examined associations with workplace access and burnout.Methods This cross-sectional study used data from 1142 nurses working in South Korean hospital settings. Nurses completed the online survey anonymously. Descriptive analysis, logistic regression, and Shapley value assessment were conducted.Results Pain relievers (44.2%), IV drips (26.8%), and antibiotics (13.5%) were the most commonly misused drugs among hospital nurses. Accessibility in the workplace was high, with nurses reporting frequent administration of IV drips, pain relievers, and antibiotics and perceiving these drugs as easily accessible. Logistic regression demonstrated that perceived availability was significantly related to misuse across all drug types. Burnout was associated with IV drips, sleeping pills, and steroids, increasing the likelihood of misuse. Shapley feature importance analysis highlighted perceived availability as the most influential factor for IV drips, pain relievers, and steroids, while burnout emerged as crucial for antibiotics and sleeping pills. Notably, age played a significant role in appetite suppressant misuse, distinguishing it from other drugs.Conclusion Our results revealed that workplace access and burnout are associated with nurses' prescription drug misuse. Effective educational strategies are essential for enhancing nurses' willingness to seek help for personal health issues. Hospital organizations play a crucial role in facilitating access to healthcare and fostering a supportive environment for nurses to seek treatment when necessary. Additionally, governmental policies should prioritize the implementation of active surveillance systems to monitor medication usage in healthcare settings, thereby mitigating drug misuse among healthcare professionals. By addressing these issues, we can ensure the well-being of nurses and promote a safer healthcare environment.
