The aim of this study is to determine the effect of cooperation between physicians and nurses working in ‎surgical clinics on the tendency of nurses to make medical errors. The research was carried out in a ‎descriptive manner at Yozgat Bozok University Research and Application Center surgical units between April-‎May 2021. 130 surgical nurses and 40 surgeons were included in the study. In the evaluation of the data, ‎independent two-sample t-test, Mann-Whitney U test, one-way analysis of variance, Duncan test, Kruskal ‎Wallis test, Pearson correlation coefficient, and regression analysis were used. When the Jefferson Physician ‎and Nurse Professional Collaboration Scale mean scores of physicians and nurses were examined; the mean ‎score of nurses was 52.2±5.8, and the mean score of physicians was 50.7±4.6. Nurses' Malpractice Tendency ‎Scale mean score was determined as 236.1±16.5. It was determined that when the Jefferson Physician and ‎Nurse Professional Collaboration Scale score of the nurses increased by one unit, the Malpractice Tendency ‎Scale score increased by 1.247. Statistically, it was determined that there was a weak positive relationship ‎‎(p<0.05). The existence of a healthy and effective cooperation system between physicians and nurses in ‎surgical units is important in preventing medical errors. In our study, it was determined that the physician-‎nurse relationship in surgical units had an effect on the medical error tendency of nurses. In line with the data ‎obtained, it is recommended to measure the reflections of the trainings on the cooperation in order to ‎increase the effective trainings in changing the professional communication within the team on doctor-nurse ‎cooperation in a positive way and to strengthen the concrete data.
