Objective To investigate the status of knowledge, attitudes and practice of advance care planning in community medical staff, in order to provide the basis for the promotion and implementation of advance care planning in the community. Methods A total of 114 community medical staff were selected from 6 community hospitals in Beijing, and a self-designed questionnaire about knowledge, attitudes and practice of advance care planning was used to investigate the included staff. Results The correct rate of answering the knowledge questionnaire of advance care planning was 53.87%, and the attitude score was (4.06±0.83) points, which was slightly above the middle level.There were significant differences in attitude scores among medical staff with different positions and working years (P＜0.05,P＜0.01). The behavior score was (3.35±0.95) points, which was at medium level. There were significant differences in behavioral scores among medical staff with different educational backgrounds, occupational types, positions, technical titles and whether they had heard of advance care planning (P＜0.05,P＜0.01). Conclusion Community medical staff have a positive attitude towards advance care planning, however, the level of knowledge and practice are low.We need to strengthen comprehensive and systematic training about relevant knowledge for community medical staff, and take into account various aspects of law, ethics and morality, in order to prepare for the popularization and promotion of advance care planning in the community.
