Background and Aims Exploring the mechanism influencing the choice of hospital among patients is important to render better care to them. The main purpose of this study is to evaluate the relationship between outpatients’ different internal factors (sociodemographic and psychological characteristics) and different external factors (provider characteristics) regarding their choice of hospital. Methods The data obtained via questionnaire was analyzed with a linear regression model to verify the relationship between outpatients’ internal and external factors. In addition, for external factors, we built a score reflecting a comprehensive hospital's “hard power” (diagnosis and treatment technology and expertise, i.e., to say, the curative capability) and “soft power” (whether the environment for seeing a doctor is convenient and cheap, etc.) factors which influence the choice of outpatients, and the factors were given different points and weighted according to the option's order of the questionnaire. Results We did not see evidence that internal factors such as gender, age, birthplace, and having or not having medical insurance had an effect on the comprehensive external factors of the hospital's choice ( p > 0.05). However, statistically significant differences were found ( p < 0.001) that outpatients who usually resided near Jiaxing valued hospitals’ “hard power” to a greater extent than did outpatients who lived in Jiaxing city, otherwise, “soft power” was prioritized. Similarly, outpatients who recognized themselves as having serious diseases valued hospitals’ “hard power” to a greater extent than those with moderate or minor diseases, otherwise, “soft power” was prioritized ( p = 0.03). Conclusion By enhancing the hospital's “soft power,” the managers of small hospitals could attract different outpatients from large hospitals, such as outpatients with minor or moderate diseases. Moreover, the regional health service organizations should promote the building of first‐ and second‐level hospitals near cities to retain more outpatients and to achieve outpatients’ diversion from large tertiary hospitals.

Background China established the Tiered-network Healthcare Delivery System (THDS) in 2015 to address the disproportionate number of patients attending tertiary hospitals relative to primary- or secondary-care institutions. Although the reported number of outpatients visiting tertiary hospitals is slowly decreasing, numerous patients choose to visit them regardless of their disease’s severity. To effectively implement the THDS, this article explored the relationship between patients’ sociodemographic and belief characteristics and their healthcare-seeking behavioral decision-making in China. Methods Data obtained through questionnaires were analyzed using decision tree and logistic regression models to explore outpatients’ characteristics and medical decision-making using comprehensive feature data. Moreover, further statistical analyses were conducted on the outpatient data obtained from the regional population health platform in Jiaxing, China. Results The decision tree model revealed that whether outpatients have medical insurance is the primary factor guiding their healthcare-seeking behaviors, with those without medical insurance more likely to choose primary or secondary hospitals to treat minor diseases. For those with medical insurance, profession is the main factor, with industrial workers more inclined to choose primary or secondary hospitals for minor diseases. The logistic regression analyses revealed that outpatients without insurance and who were not freelancers or individual owners were more likely to choose primary or secondary hospitals for minor diseases. Further statistical analysis of the data from the Jiaxing population health platform showed that, for minor or general diseases, outpatients without medical insurance and employed as farmers tended to choose primary and secondary hospitals over tertiary hospitals. Conclusion The three analyses yielded consistent results: in China, medical insurance and patients’ profession are the most important factors guiding outpatients’ healthcare-seeking behaviors. Accordingly, we propose that the government should focus on economic reforms to increase outpatients’ visits to primary and secondary hospitals and diagnosis-related groups’ payment of medical insurance to decrease the admittance of patients with minor diseases in large tertiary hospitals. Meanwhile, the government should correct patients’ belief prejudice about selecting hospitals through corresponding publicity.
