Objective To know the change of medical care and health services utilization of Yayuncun community residents in Beijing. Methods Using the prospective study, residents above 15 years old were selected to answer the Beijing Typical Community Resident Questionnaire designed by the local researchers. In 2004 and 2005, the baseline survey was carried. From 2006 to 2008, same questionnaire was used to follow-up survey, and 1412 residents were selected into the last study. Results The proportion of people who should see a doctor but not in past month were decreased, the differences among the three years were significant (P < 0. 01 ); The top three reasons that who should see a doctor but not were the "medical care costs too high", "self- felt the sickness light", "self-treatment". The residents who went to the community health agencies increased from 2006 to 2008. The medical costs ( drugs, medical fees,inspection fees) decreased from 2006 to 2008, the differences were significant (P <0. 01 ) ;The satisfaction increased from 2006 to 2008, the differences were significant ( P < 0. 01 ). Conclusion Under the comprehensive promotion of community health services in Beijing, the satisfaction and the utilization of medical care and health services were improved.
