Association of Continuity of General Practitioner Care with Utilisation of General Practitioner and Specialist Services in China: A Mixed-Method Study

Abstract

Background: Continuity of general practitioner (GP) care, widely known as the core value of high-quality patient care, has a positive association with health outcomes. Evidence about the relationship between continuity and health service utilisation has so far been lacking in China. This study aimed to analyse the association of continuity of GP care with utilisation of general practitioner and specialist services in China. Method: A cross-sectional mixed methods study was conducted in 10 urban communities in Hangzhou. Quantitative data were collected from a random sample of 624 residents adopting the self-developed questionnaire. Measurement of continuity of GP care included informational continuity (IC), managerial continuity (MC) and relational continuity (RC). With adjustment for characteristics of residents, multivariate regression models were established to examine the association of continuity of GP care with the intention to visit GP, frequency of GP and specialist visitations. Qualitative data were collected from 26 respondents using an in-depth interview, and thematic content analysis for qualitative data was conducted. Results: Quantitative analysis showed that the IC was positively associated with the intention to visit GP and frequency of GP visitations. Those people who gave a high rating for RC also used GP services more frequently than their counterparts. MC was negatively associated with frequency of specialist visitations. Qualitative analysis indicated that service capabilities, doctor–patient interaction and time provision were regarded as three important reasons why patients chose GPs or specialists. Conclusions: Overall, high IC and RC are independently associated with more GP service utilisation, but a high MC might reduce specialist visitations. Continuity of GP care should be highlighted in designing a Chinese GP system.
