Preferences of patients with severe mental disorders in medical security policies: a discrete choice experiment from communities in Beijing, China
摘要
Patients with severe mental disorders in China face a heavy financial burden and are in dire need of government support to help with medical costs. This study aims to study the participation preferences of patients for these policies, and provide a basis for the next path of policies improvement. In this study, a multistage stratified sampling method was used to investigate patients in three communities in Beijing. Based on a literature review and expert consultation, we identified four attributes—Starting payment line, Reimbursement rate, Drug catalogue, and Designated institutions—each with four levels. The choice sets for the discrete choice experiment were determined through an orthogonal design.Conditional logit regression and mixed logit regression models have been constructed based on the choice preference data, while relative importance and scenario prediction analysis have been adopted to measure the emphasis level of policy attributes in patients' minds. All four policy attributes affect patients' preferences for policy participation, while the attributes in descending order of relative importance are starting payment line (29.10%), reimbursement rate (25.40%), drug catalogue(24.19%), and designated medical institutions(21.31%).Patients significantly preferred the policy option with no starting payment line (p<0.01). There are also differences in the attributes that patients with different demographic characteristics consider critical when making choices. We found that patients with lower education levels, those who are employed or retired, and older patients place a higher value on the reimbursement rate. Unemployed patients prioritize the drug catalogue. Younger female patients tend to be more concerned with the starting payment line level compared to older male patients, and unmarried patients also show a preference for the starting payment line. This study has measured demand-side preferences for policy participation from the patient's perspective. This is significant that patients significantly preferred the policy option with no starting payment line and setting community health service centers as designated medical institutions.
