Background: Relationship between physicians and nurses includes the interactive interactions to achieve a common treatment goal, i.e., improving the health and safety of the patient. The present study aimed to investigate the relationship of physician-nurses interaction with the patient safety incidents in Amir-Al-Momenin hospital in Tehran city, Iran.
Methods: This applied, analytical, and cross-sectional study was carried out in 2017. The study population consisted of all full-time physicians (N = 45) and nurses (N =186) of Amir-Al-Momenin hospital in Tehran city. They were selected using the census and convenience sampling methods. To collect data, we used a four-part questionnaire including demographic data, physicians' viewpoints about the nurse-physician interaction, nurses' viewpoints about nurse-physician interaction, and patients' safety events. Data were analyzed by SPSS ₂₂ using Fisher exact test.
Results: We found that 45 physicians (100 %) and 174 nurses (93.54 %) completed the questionnaires. The physicians reported that the nurse-physician interactions were moderate (80.0 %), good (11.1 %), and bad (8.9 %). However, nurses believed that this relationship was moderate (74.7 %), good (18.4 %), and bad (6.9 %).  A significant relationship was observed between the nurse-physician interaction and patients' safety events in 10 cases of events (p < 0.05).  
Conclusion: Patients' safety events can be related to the type of nurse-physician interaction. So, improvement of the nurse-physician interaction should be considered more seriously as an effective factor in patients' safety.
