Abstract: Objective To analyze the utilization of outpatient and inpatient prevention service,a part of standardized management,and its influencing factors among hypertension and diabetes patients.Methods Data on the utilization of outpatient and inpatient prevention service among 9 607 hypertension patients and 2 640 diabetic patients were extracted from the dataset of the Household Questionnaire Survey on Health sponsored by The National Health and Family Planning Commission and the Ministry of Finance and conducted in 2014 in 34 key counties or districts for comprehensive health reform across China.Chi-square test and multivariate logistic regression model were adopted in data analysis.Results Among the hypertension and diabetes patients,the standardized management rate were 80.2% and 78.3%;the rate of visiting a doctor during past two weeks was 41.3% and 57.3%;and the hospitalization rate was 33.2% and 52.7%,respectively.The results of multivariate logistic regression analyses showed that the main influencing factors were whether having community family physician service,age,residential place (urban or rural),and region of residence (eastern,central,or western China) for the acceptance of standardized management;type of medical insurance,compensation for utilization of outpatient service for chronic disease,education,employment status,and residential place were influencing factors for the utilization of outpatient service;and income,compensation for chronic disease outpatient service,education,and region of residence were influencing factors for the utilization of hospitalization.Conclusion Community family physician service could promote standardized management of hypertension and diabetes patients.Hypertension and diabetes patients with medical insurance for urban employees had a lower utilization rate of outpatient service but a higher utilization rate of hospitalization.The compensation for utilization of outpatient service for chronic disease could effectively facilitate utilization of outpatient service but decrease hospitalization among hypertension and diabetes patients.
