Exploring the Relationship between Sleep Quality and Cancer-related Fatigue on Breast Cancer Patients Undergoing Chemotherapy

OBJECTIVE: The purpose of this study was to analyze the correlation of sleep quality and cancer-related fatigue (CRF) in breast cancer patients undergoing chemotherapy. METHODOLOGY: This research design uses cross-sectional. The sampling method was a total sampling of all breast cancer patients undergoing chemotherapy from August to October 2024 in a hospital in Banda Aceh, Aceh province, with a total of 100 respondents. Sample criteria are more than 18 years old, not experiencing severe stress, and not experiencing psychiatric disorders. Data were collected using the Pittsburgh Sleep Quality Index questionnaire and Piper Fatigue Scale 12. Data were analyzed using univariate analysis, t-test, and Pearson correlation. RESULTS: The mean age of respondents was 47.63±8.35 years; all respondents were Muslim, had a partner 74.0%, had university-level education 39.0%, unemployed 53.3%, and 38.0% had the second chemotherapy cycle. The mean CRF in respondents with good sleep quality was 3.85±1.20, while in respondents with poor sleep quality, it was 4.83±1.57, and there was a significant difference at p-value 0.004. Sleep quality significantly related to CRF (r = 0.635, p-value <0.001) CONCLUSION: The sleep quality of breast cancer patients undergoing Chemotherapy is closely related to CRF. The better the sleep quality, the lower the fatigue level. It is recommended that healthcare providers should update the design of facilities and rooms for chemotherapy administration to improve sleep quality.
