effect of kefir on symptom management and quality of life in oncology

Conditions: Breast Cancer; Colorectal Cancer

Summary: this study was planned as a randomized controlled prospective experimental study to determine the effect of kefir on symptom management and quality of life in oncology patients receiving chemotherapy. the population of the study consisted of 600 cancer patients who received chemotherapy in the outpatient chemotherapy unit of a university hospital between june 1, 2023 and february 1, 2024. g\*power 3.1 package program was used to determine the number of samples. the sample size to ensure the power of the test (1-β = 0.80) was determined as a minimum of 26 people for each group. considering the possibility of losses, 106 patients were included in the study. data from 22 patients who were followed up during the preparation phase of the study were not included in the study. simple random sampling method was used to avoid bias in providing patients to be included in the study before the data collection phase. with the computer-based randomization method, patients were numbered in the order of arrival and divided into experimental and control. the sample of the study was determined as 84, 42 in the experimental group and 42 in the control group. in collecting data, "individual information form, nightingale symptom assessment scale (nsd-s), fact-g quality of life scale, who mucositis evaluation form, rhodes nausea vomiting gagging index, asco diarrhea assessment scale and constipation assessment scale" were used. cas)" was used.
