Abstract: Objective To understand the difference between the results of the higher-level assessment and the internal assessment of family doctors' contracted services in community health service institutions in suburban areas of Beijing, analyze the reasons and put forward countermeasures. Methods Collection of the assessment data of family doctor contracted service in a community health service center in Beijing suburban mountainous area from January 2018 to April 2018 was made, including higher-level and internal assessment. Institutional internal assessment personnel are responsible for carrying out internal assessment after unified training; at the same time, higher authorities carry out the same project assessment of the institution. Examiners at both levels checked and understood the amount of work completed by the organization via the information system. The telephone interview method was used to understand the residents' perception of the service and to judge the authenticity of the contracting work. Assessment was made regarding the quality of family doctor's contract service and health management of hypertension and diabetes patients. The authenticity and effectiveness of the work of the organization were comprehensively analyzed, and the development of the work was assessd according to above results. The study compared and analyzed the differences between the internal assessment results of the organization and those of the higher authorities. Results The authenticity and standardization of internal assessment are generally higher than the results of higher-level assessment. Conclusion In the internal assessment, the assessors are easy to communicate with the residents and get the cooperation of the residents, so they can get more real information.However, the ability of grass-roots performance appraisal personnel needs to be improved, and attention should be paid to avoid the influence of supervisory factors.Superior assessment is normative, but it is not easy to get the cooperation of residents.Therefore, it is suggested that we should make full use of objective assessment methods and take full account of the economic and cultural characteristics of mountainous areas, improve the methods of assessment of family doctors' contractual services, so that they can truly reflect the actual working conditions in mountainous areas and effectively promote the development of family doctors' contractual work.
