Background: Effective communication is an essential element of effective healthcare team and patient safety. Global research emphasises the need of effective communication for patient safety and nurse satisfaction, however language obstacles and hierarchical structures continue to impair Saudi Arabian healthcare environments. Previous studies have examined communication and safety culture independently, with limited evidence of studies that explore the relationship between nurses’ communication satisfaction and their perceptions of patient safety culture within Saudi operating theaters. Objectives: This study aimed at evaluating the relationship between nurses’ communication satisfaction and culture of safety among operating theatre nurses in a tertiary hospital in Saudi Arabia. Research Design & Setting: A cross-sectional correlational design was used to conduct this study in a military tertiary hospital in Riyadh, Saudi Arabia. A convenience sampling method was used to sample a total of 116 participants operating theatres in the hospital. Methods & Materials: Data collected using two validated instruments: the Communication Satisfaction Questionnaire (CSQ) and the Hospital Survey on Patient Safety Culture (HSOPS) to examine how communication satisfaction affects patient safety culture. Analysis: analysis conducted through SPSS using descriptive statistics, repeated-measures ANOVA, t-tests, and Pearson correlation. While One Way ANOVA used for data scoring, Cronbach’s Alpha used to assess the reliability coefficient. Results: Showed a Pearson correlation of r = 0.206 with p < 0.05, showing a weak but statistically significant relationship. In organizational and healthcare research, these findings suggest a significant association, even when the strength is ordinary. This positive correlation means that as communication satisfaction increases, nurses’ perceptions of patient safety culture also improve. Conclusion: A significant positive correlation is found between overall satisfaction and overall patient safety perception. The findings consistently highlight communication as a central component of a strong and healthy safety culture.
