This descriptive and cross-sectional study was conducted to determine sleep quality and factors affecting sleep in patients who have been operated mastectomy surgery. The sample of the study is comprised of those patients (n=110) who visited general surgery clinic in an Education and Research Hospital in Ankara between January 1 and July 30, 2020 for checking after their mastectomy surgery, agreed to participate in the study and met research criteria. The informative form related to characteristics of patients and PSQI have been used while collecting data. The numbers and percentages related to data, t test, and Kruskal Vallis test have been used in the evaluation of data; Chi-Square and Fisher's Exact test were used for comparison of groups; Spearman's Correlation analysis have been employed for examining relationships. Written permission from the ethics committee and the institution, and written consent from the patients were obtained to conduct the study. After mastectomy surgery of patients participated in the study, the average PSQI score of them was 10.19 ± 3.44 (2-18). After mastectomy surgery of the patients, it was determined that 60.9% of the patients had a decrease in sleep quality, 89.1% had poor sleep quality, and 81.8% had a change in the postoperative sleeping position. There was no statistically significant difference between the findings related to characteristics of the patients and the PSQI mean scores (p> 0.05). A statistically positive weak correlation was detected between the amount of time elapsed after mastectomy surgery and the PSQI mean scores (p> 0.05, r = 0.171). A statistically negative weak correlation was found between the amount of liquid consumed by patients daily and the average PSQI score (p> 0.05, r = -0.026). According to the result of the study, patients who have poor sleep quality and changes in their sleep habits after mastectomy surgery should be given training to improve sleep quality before discharging from hospital. In the field of nursing, it is recommended to conduct experimental studies to increase the sleep quality of patients.
