Advance directives of lung cancer patients and caregivers in China: A cross sectional survey

BACKGROUND: This study aimed to investigate lung cancer patients and attitudes of their caregivers toward advance directives (ADs) in China. METHODS: A cross sectional study was conducted in the Department of Oncology outpatient clinic in West China Hospital, Sichuan University. A questionnaire was used to survey the attitudes of lung cancer patients and caregivers toward ADs. RESULTS: A total of 148 lung cancer patients and 149 caregivers were enrolled into the study. Of these, 94.6% and 89.9% of patients and caregivers had not heard of AD and none of those in the study had ever signed an AD. A total of 79.7% patients and 75.2% caregivers were willing to sign ADs after they were provided with information. Patients who preferred the end of life period to sign ADs were 5.4 times more likely to have ADs than patients who chose to sign ADs when their disease was diagnosed (P < 0.05, 95%CI [1.27–22.93]). Caregivers who were reluctant to undergo chemotherapy when diagnosed with cancer were 2.16 times more likely to sign ADs than those willing to receive chemotherapy (P < 0.05, 95%CI [1.20–3.90]). CONCLUSIONS: In China, lung cancer patients and their caregivers showed lack of knowledge about ADs, and the completion rate of ADs was extremely low. However, participants were positive about ADs and public education on ADs may help to increase the completion rate of ADs in China.
