Background: Physician-patient interactions are a complex process and inappropriate communication can become a problem. Due to the importance of this issue, this study was conducted to identify the relationship between physician ethics and patient satisfaction and provide an effective communication-cultural model. Methods: The research method used in this study was descriptive - correlation and using the calculated correlation coefficients, a structural model was developed. The statistical population of the present study was all patients admitted to medical centers affiliated to Kermanshah University of Medical Sciences and Health Services in 1398 and the sample size was selected based on Cochran's formula equivalent to 171 people. Necessary information was collected through two questionnaires: standard questionnaire of communication with patient Vakili et al. In order to assess interpersonal communication skills and a researcher-made questionnaire of observance of physician's medical ethics and patient satisfaction taken from the patient rights charter approved by the Ministry of Health. Results: The findings indicate that the patriarchal model has been able to predict patient satisfaction. The results also showed that there is a significant relationship between the informative model and patient satisfaction. Also, based on the results, it was found that the interpretive model, bilateral participation model and instrumental model could not predict patient satisfaction. The results also show that the contract model has been able to predict patient satisfaction with an effect factor of 0.33 and a significant level of P < 0.01. Finally, there is a significant relationship between the contract model and patient satisfaction. Conclusions: Based on the analysis of the obtained data, the most type of model approved by patients was the paternal model, in which there is much less interaction between the patient and the physician than other communication models.
