ABSTRACT

Objective To explore the correlation of oral chemotherapy adherence and illness perception among colorectal cancer patients at different stages of chemotherapy in order to provide evidence for improving oral chemotherapy adherence among colorectal cancer patients in clinical practice.Methods A prospective longitudinal study was employed.Convenience sampling was used to recruit 132 cases of colorectal cancer patients.Data of general information,oral chemotherapy adherence and illness perception were collected by questionnaire.Results At different stages of chemotherapy,patient's score of oral chemotherapy adherence were 7.24±1.15,6.97±1.43,6.95± 1.17;patients' illness perception scores were 40.12±9.47,39.91±8.65,37.01±6.83.Oral chemotherapy adherence was negatively correlated with illness perception (r=-0.225,P＜0.05;r=-0.279,P＜0.01;r=-0.277,P＜0.01).Conclusion Higher level of patient's illness perception was related to worse oral chemotherapy adherence.Nurses should instruct patients to understand the disease and the treatment correctly,to reduce the adverse impact on patients' life and emotion,and to improve patients' compliance with oral chemotherapy.
