ObjectiveTo evaluate the current state of family doctor contract services (FDCS) in Beijing, identify the roles of family doctors who have worked with disabled older adults and investigate the barriers and facilitators faced by family doctors in providing care for them.DesignA convergent mixed methods study was carried out from October 2020 to January 2021 to collect and analyse both quantitative and qualitative data. The integration strategies in this study were connecting the results of the quantitative phase to data collection of the qualitative phase.SettingA multi-stage sampling strategy was used to select 15 community health centres (CHCs) in four districts of Beijing. Of the four districts, two were from urban areas and two were from rural areas.ParticipantsThe inclusion criteria for participants were (1) family doctors, (2) contracted with disabled older adults, (3) engaged in related work for disabled older adults more than 6 months.MethodsA cluster sampling of 283 family doctors was used in the questionnaire. A purposive sample of 30 family doctors from the same CHCs was selected during the same period. Frequency and rank, rank-sum test, Kruskal-Wallis test were conducted in qualitative data analysis, the views of the interviewees were analysed through the thematic framework method.ResultsCurrently, family doctors provided various services to satisfy the health needs of disabled older adults, while the usage of FDCS for disabled older adults is affected by many factors. The differences of the importance of family doctors’ role (p<0.001) and service satisfaction (p=0.004) were significant among four districts. Compared with contracted health senior citizens, this study has identified five unique roles of family doctors, including ‘psychological consultant’, ‘rehabilitation physiotherapist’, ‘health educator’, ‘health manager’ and ‘family health guardian’. Moreover, family doctors are confronted with a myriad of barriers (including high risks in the process of home visits, a lack of supervisory and incentive mechanisms, insufficiency of time and energy, etc) and facilitators (including establishing a doctor–patient trust relationship, developing humanistic care services, etc) in the FDCS for disabled older adults.ConclusionsFamily doctors play a pivotal role in the FDCS for disabled older adults, while the effect and quality of FDCS in China needs to be improved. It is suggested that further research needs to focus on solving existing barriers of FDCS to optimise the health of disabled older adults and improve the quality of their lives.
