Assessing the quality of primary healthcare for diabetes in China: multivariate analysis using the China Health and Retirement Longitudinal Study (CHARLS) Database

Abstract

Objective To assess the quality of primary healthcare (PHC) for patients with diabetes in China from 2011 to 2015.Setting This study analysed data on 1006, 1472 and 1771 participants with diabetes who were surveyed in 2011, 2013 and 2015, respectively, in the China Health and Retirement Longitudinal Study, a nationally representative survey conducted in 29 provinces of China.Outcome measures The study measured the proportions of patients with diabetes who received diabetes-related health education, examinations and treatments, as well as the hospital admission rate due to diabetes of these patients. Multilevel logistic regression was used to adjust sociodemographic variables.Results According to the multivariate analysis, the proportion of patients who received diabetes-related health education decreased significantly (OR=0.74, 95% CI 0.61 to 0.90), and the proportion of those receiving examinations and treatments remained unchanged from 2011 to 2015. Diabetes-related hospitalisation increased from 4.01% in 2011 to 6.08% in 2013 (OR=1.47, 95% CI 0.97 to 2.22), and recurrent hospitalisations increased from 18.87% in 2011 to 28.45% in 2015 (OR=1.78, 95% CI 1.44 to 2.20). The proportions of patients with diabetes-related and recurrent hospitalisations in western China were higher than those in the east (OR=1.80, 95% CI 1.13 to 2.87; OR=1.92, 95% CI 1.50 to 2.45).Conclusions Nationally, the analysis of patient-reported process and outcome indicators cannot confirm that the quality of PHC has improved in China during 2011–2015. Regional disparities in primary diabetes care require urgent resource allocation to western China. Establishing a national quality registry for PHC, which transparently reports outcomes by region and social-economic position, is essential for countries sharing the challenge of improving both quality and equity of PHC.
