Background General practitioners(GPs) may be the most appropriate provider of clinical preventive services,and outpatient consultations may be the most suitable delivery way. However,the level of clinical preventive services provided by GPs during outpatient consultations is unknown in China. Objective To examine the level of clinical preventive services provided by GPs during consultations in outpatient primary care settings in China. Methods This study was implemented during July 2018 to January 2019. By using a three-stage sampling,18 GPs from 8 community health centers in Guangdong Province,and 649 patients managed by them were selected. The data of outpatient consultations were obtained with direct observation and audio recording,in which the information of preventive interventions was described structurally and quantitatively using the internationally used Davis Observation Code. Results Of the 649 cases,186(28.7%) received at least one kind of clinical preventive service. Only 3 GPs provided clinical preventive services in more than 50% of their outpatient consultations.Patient nutrition counseling,disease screening and vaccination counseling and sleep counseling with recommended tips offered by GPs,accounted for 13.4%,9.4%,5.6% of all consultations,respectively. And the average consultation duration for the above-mentioned services was(17.61±18.37),(15.77±15.62) and (13.53±18.59) seconds,respectively,among the service recipients. Conclusion The level of clinical preventive services provided by Chinese GPs during outpatient consultations is still very low,which may considerably fall behind that in foreign countries.
