ObjectiveA number of factors contribute to the utilisation of family doctor contract services (FDCS) in China. This study aims to measure the preferences of the elderly for the FDCS and identify the key factors (and their relative importance) that may guide policymakers in more accurately providing the FDCS.Participants and methodsA discrete choice experiment was performed to elicit the preferences for FDCS among the rural elderly in China. Attributes and levels were established based on qualitative methods. Four attributes were included: service type, service package, physician’s reputation and annual contract costs. A D-efficient design was used to create a set of profiles that represented FDCS. The survey was conducted face to face using a sample of participants aged 60 and above in rural areas of Anhui Province. The data were analysed using a latent class logit (LCL) model.ResultsA total of 545 valid questionnaires were included in the analysis. The average age of the participants was 69.44 (SD 5.80). Two latent classes were identified with the LCL model. All four attributes proved statistically significant at the level of both the population mean and the two classes. The rural elderly showed a preference for FDCS with a relatively good reputation, lower annual contract costs, the basic service with the add-on of chronic disease service and home visit. Age, gender, education, self-reported health status and the number of chronic diseases were found to be associated with latent class membership.ConclusionIn this study, the physician’s reputation had the largest impact on the rural elderly’s choice of FDCS. Policy recommendations included the need to strengthen family doctor team training, devote greater attention to improving the family doctor’s medical skills and service approaches, and increased FDCS efficiency for the care of the rural elderly.

IntroductionThe objective of the Comprehensive Intervention of Oral Disease for Children (CIODC) in China is to prevent dental decay for school-aged children and provide free prevention services in pilot areas beginning in 2008. It is a potentially affordable, acceptable and effective prevention strategy to use for more school-aged children in the future. There is a shortage of robust evidence regarding the cost-effectiveness, feasibility and scalability of prevention strategies for dental decay for school-aged children in China. This study aims to provide a comprehensive evaluation, including an economic evaluation and process evaluation, to better understand how and why the public health programme may be effective and economical.Methods and analysisMixed methods will be used in this study. Cost-effectiveness analysis (CEA) will be conducted from a societal perspective, based on a modelling study over 6 years (from age 7 to 12) in terms of the incremental cost-effectiveness ratios per dental decay averted. The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework informed the process evaluation. An estimated 48–80 semistructured interviews with service providers, patient parents/caregivers and decision-makers under the logic model will be used in the progress evaluation to describe the feasibility and sustainability of CIODC.Ethics and disseminationThe study has all necessary ethical approvals from the Ethics Committee of Anhui Medical University (number 2021H030). All participants will provide informed consent prior to participation. Findings will be disseminated through conference presentations and scientific publications in peer-reviewed journals.
