Abstract: Background  In China，community health centers are classified as primary healthcare institutions in accordance with the hierarchical medical system，and quality improvement of diagnostic and treatment services delivered by them is conducive to meeting people's growing demand for medical services.Objective  To shorten patient waiting time for disease screening in a community health center by using a shared screening scheme，improving service efficiency，and patient satisfaction.Methods  Disease screening in community health centers was deemed as a queuing system，and was optimized by a shared screening scheme，then its characteristics were compared with those of other three screening schemes.Results  Queuing-model based analysis of patient waiting time for disease screening by using 4 optimization schemes derived different outcomes using different control strategies.If optimizing the disease screening procedure without increasing the investment，patient waiting time could be shortened by the shared mode，namely，3 community health centers，and physicians from these centers carried out disease screening in collaboration.Conclusion  Queuing theory can be used as an auxiliary tool for primary care managers to optimize the service system with different control factors.In addition，sharing healthcare services in primary care improves the service efficiency and patient satisfaction，promotes rational medical resources allocation，and enhances the comprehensive strength of primary care system.
