Summary: Background: China’s National Essential Public Health Service Package (NEPHSP) aims to promote health for all at the primary health care level and includes a focus on hypertension and type-2 diabetes mellitus (T2DM). However, there are limited contemporary data to quantify the care cascades of hypertension and T2DM in primary health care. Methods: This cross-sectional study involved individual level linkage of routinely collected data from the NEPHSP, health insurance claims and hospital electronic health records, from four diverse regions in China, including Xiling District (central China), Wenchuan County (western), Acheng District and Jiao District (northern). We first compared numbers of people aged ≥35 with a recorded diagnosis of hypertension and T2DM against expected numbers derived from epidemiological data. We then constructed care cascades to assess the percentages (1) enrolled in the NEPHSP, (2) adherent to the follow-up care of NEPHSP, (3) receiving medication treatment, and (4) having hypertension and/or T2DM controlled. Findings: In the four regions, the total numbers of people aged ≥35 diagnosed of hypertension and T2DM from any data source were 149,176 and 50,828, respectively. This was estimated to be 46.0% (95% confidence interval [CI]: 45.8%–46.2%) and 45.6% (95% CI: 45.3%–45.9%) of the expected totals for hypertension and T2DM, respectively. Among those diagnosed, 65.4% (95% CI: 65.1%–65.6%) with hypertension and 66.1% (95% CI: 65.7%–66.5%) with T2DM were enrolled in the NEPHSP, respectively, in which 54.8% (95% CI: 54.5%–55.2%) with hypertension and 64.7% (95% CI: 64.1%–65.2%) with T2DM were adherent to the required services. Among those enrolled, the overall treatment rates were 70.8% (95% CI: 70.6%–71.1%) for hypertension and 82.2% (95% CI: 81.8%–82.6%) for T2DM. Among those treated, a further 80.9% (95% CI: 80.6%–81.2%) with hypertension and 73.9% (95% CI: 73.3%–74.4%) with T2DM achieved control. These results varied considerably across regions, with the northern sites showing relatively higher enrolment rates while the central site had higher control rates. Interpretation: Detection and control rates for hypertension and T2DM are suboptimal in these four regions of China. Further strategies are needed to improve people’s enrolment in and adherence to the NEPHSP and strengthen care delivery processes. Of note, our estimations of the diagnosis rates for each region are based on national level large epidemiological data. The interpretation of these data needs caution due to potential bias caused by regional variations.

BackgroundThe national essential public health service (NEPHS) has been in operation for more than a decade. Numerous studies examined the utilization of NEPHS by migrants and the factors that influence it, but few examined the effect of NEPHS awareness and utilization on the health of inhabitants, particularly migrants. The purpose of this study is to ascertain the level of awareness and utilization of NEPHS, as well as to examine their health-improving effects on migrants.MethodsBased on the data from the 2017 China Migrants Dynamic Survey, linear probability model, ordered logit model and the propensity score matching methods were employed to investigate impact of awareness and utilization of NEPHS on the health among Chinese migrants. Mediating effect model were used to identify the mechanism of the impact of NEPHS on health.ResultsThe findings indicated that migrants' awareness and utilization of NEPHS are still insufficient. After adjusting for other factors, the study discovered that increased awareness and use of NEPHS had a beneficial influence on migrants' self-rated health. Further heterogeneity analysis revealed significant disparities in the health consequences of NEPHS awareness and utilization across subgroups. The effect of increased awareness and usage of NEPHS on health is stronger for middle-aged and elderly people, women, and low-educated migrants with urban household registration. The estimated results of the mediating effect model supported the mechanism that increased NEPHS awareness among the floating population could encourage its utilization and further improve the floating population's health.ConclusionsGiven that migrants' NEPHS utilization is still low and that NEPHS utilization has a positive effect on health, some targeted strategies, such as a variety of new media communication methods, health education related to occupational disease and tuberculosis prevention, and targeted NEPHS projects for specific groups, such as men, young and middle-aged groups, those with a high level of education, and rural migrants, should be conducted to improve the health of migrants.
