The purposes of this study are to explore consumers’ knowledges, attitudes, and willingness to attend the family physician system. A structured questionnaire was used to collect data. A total of 1200 sampled subjects were selected by quota sampling from a population of 16,191,200 people. T-test and chi-square tests were conducted to explore consumers’ willingness to attend and their characteristics. A logistic regression analysis was performed to understand factors related to consumers’ willingness to attend the family physician system. Among the sampled subjects, 50.3% thought it is “very appropriate” or “appropriate” to implement a family physician system, and 61% “agreed” or “greatly agreed” to the implementation of a gatekeeper system. In addition, 63.3% expressed “willing” or “very willing” to attend a family physician system. The logistic regression analysis found that those who thought it is appropriate to implement a family physician system (OR=6.184, 95% CI=4.686~8.160) and who have monthly incomes between 40,000 and 59,000 (OR=1.520, 95% CI=1.022~2.261) were more likely to willingly attend a family physician system. Those who have at most a junior high school degree (OR=0.345, 95% CI=0.190~0.627) and senior high school degree (OR=0.673, 95% CI=0.473~0.958) were less likely to willingly attend a family physician system. As to the model of family physician system, most respondents preferred that (1) they can choose to visit a single or a group of family physicians if they feel sick; (2) family physicians should provide preventive care, drug, nutritional, and mental consultations, as well as routine medical care; (3) they are free to visit any family physicians even after they have their own family physicians; (4) they are free to select hospital-based or clinic-based physicians as family physicians; (5) they can change their family physicians every year. It is recommended (1) to gather other countries’ experiences in the implementation of family physician system; (2) to educate consumers on the framework of Taiwan’s family physician system; (3) to integrate consumers’ opinions into the model of Taiwan’s family physician system.
