The objective of this study is to investigate the impact factors on the health of inpatients with colorectal cancer after receiving chemotherapy. The cross-sectional study was conducted with convenience sampling and the interview strategy of the survey was used in thirty-six patients. The instruments included Nutritional Assessment, Symptom Distress Scale, Prevent Infection Assessment and Barthel Index. The study found that the impact factors on the health of the colorectal cancer patients after chemotherapy include a higher percentage of the malnutrition, insufficiency of oral hygiene maintenance, lack of knowledge of the infection prevention, a higher frequency of emotional instability, and poor daily activity. The result of this study provides information about the impact factors and the demand of healthcare for the colorectal cancer patients after chemotherapy. Hopefully, this will inspire the patients with colorectal cancer who receive chemotherapy to develop the motivation of caring for themselves and increase their quality of life.
