Primary care institutional characteristics associated with hypertension awareness, treatment, and control in the China PEACE-Million Persons Project and primary health-care survey: a cross-sectional study

Association between fibrosis-4 index and cognitive impairment in elderly patients with hypertension: A cross-sectional study

The fibrosis-4 index (FIB-4) is a noninvasive fibrosis test that is recommended for patients who are at risk of developing hepatic fibrosis. The aim of the study was to explore the correlation between FIB-4 index and the decline of cognitive function among older patients with hypertension. The study used a cross-sectional design to analyze data obtained from the NHANES 2011-2014. The significance of the FIB-4 index correlation with cognitive function in individuals over the age of 60 was evaluated via multivariate regression models. The nonlinear link was described and fitted smoothed curves. There were a total of 2039 participants in the study, and those with a higher FIB-4 index were more susceptible to developing cognitive decline. In the completely adjusted model, the association remained statistically significant between the FIB-4 index and poor cognitive function as measured by CERAD: Total Score (OR = 0.72, 0.57-0.91), Animal Fluency Score (OR = 0.66, 0.48-0.91), and Digit Symbol Score (OR = 0.36, 0.17-0.77). A nonlinear association was found between the FIB-4 and poor cognitive ability: Total Score, CERAD: Score Delayed Recall, Digit Symbol Score, and Animal Fluency Score. In elderly patients with hypertension, a high FIB-4 index is correlated with an increased prevalence of cognitive decline. Hence, the FIB-4 index could potentially serve as a valuable tool for determining individuals with hypertension who are susceptible to both liver-related complications and cognitive impairment.

Cardiometabolic factors and population risks of cardiovascular disease in community-dwelling adults with varied blood pressure statuses

AIMS

To examine the differential associations between cardiometabolic risk factors and cardiovascular disease (CVD), and to evaluate the population-attributable fractions (PAFs) for CVD among community-dwelling adults with varied blood pressure (BP) statuses.

METHODS

This prospective cohort study included participants without prevalent CVD from a subcohort of the China Patient-Centred Evaluative Assessment of Cardiac Events Million Persons Project. Participants were divided into four BP groups according to the American College of Cardiology/American Heart Association guidelines. The study exposure comprised the selected cardiometabolic risk factors, including waist circumference (WC), body mass index, (BMI) heart rate, fasting blood glucose (FBG), low-density lipoprotein cholesterol, and remnant cholesterol. The outcome was hospitalizations for CVD. Cox proportional hazard models were conducted, and the PAFs were calculated in the analysis.

RESULTS

Among the 94 183 participants (39.0% were men, mean age: 54.2 years), 26.6% had Stage 1 hypertension and 30.8% had Stage 2 hypertension. A total of 6065 hospitalizations for CVD were captured after a median follow-up of 3.5 years. BP (per 1-standard deviation [SD]: hazard ratio [HR] 1.34, 95% confidence interval [CI] 1.29, 1.40), FBG (per 1-SD: HR 1.16, 95% CI 1.14, 1.19) and WC (per 1-SD: HR 1.41, 95% CI 1.36, 1.47) were three major contributors to CVD events. BP status significantly modified the associations of abdominal obesity, suboptimal BMI, suboptimal heart rate and abnormal FBG with CVD, with stronger associations with CVD observed in optimal BP groups compared to hypertensive groups (p for risk factor-by-BP group interaction <0.05). Participants with all cardiometabolic risk factors were at the highest risk for CVD, accounting for 35.6% (95% CI 30.0, 40.8) of the PAF for CVD. Among the risk factors, BP control explained the highest PAF for CVD (15.1%, 95% CI 8.2, 21.4) The overall PAFs of cardiometabolic risk factors for CVD were higher among the normotensive participants compared to the hypertensive participants.

CONCLUSIONS

The awareness and control rates of hypertension were extremely low among Southern Chinese adults. BP status significantly modified the associations between cardiometabolic risk factors and CVD, and the overall PAFs for CVD were higher among people with normal BP. Dedicated efforts are needed to improve the management of cardiometabolic factors.

Learning implementation of a guideline based decision support system to improve hypertension treatment in primary care in China: pragmatic cluster randomised controlled trial

OBJECTIVE

To evaluate the effectiveness of a clinical decision support system (CDSS) in improving the use of guideline accordant antihypertensive treatment in primary care settings in China.

DESIGN

Pragmatic, open label, cluster randomised trial.

SETTING

94 primary care practices in four urban regions of China between August 2019 and July 2022: Luoyang (central China), Jining (east China), and Shenzhen (south China, including two regions).

PARTICIPANTS

94 practices were randomised (46 to CDSS, 48 to usual care). 12 137 participants with hypertension who used up to two classes of antihypertensives and had a systolic blood pressure <180 mm Hg and diastolic blood pressure <110 mm Hg were included.

INTERVENTIONS

Primary care practices were randomised to use an electronic health record based CDSS, which recommended a specific guideline accordant regimen for initiation, titration, or switching of antihypertensive (the intervention), or to use the same electronic health record without CDSS and provide treatment as usual (control).

MAIN OUTCOME MEASURES

The primary outcome was the proportion of hypertension related visits during which an appropriate (guideline accordant) treatment was provided. Secondary outcomes were the average reduction in systolic blood pressure and proportion of participants with controlled blood pressure (<140/90 mm Hg) at the last scheduled follow-up. Safety outcomes were patient reported antihypertensive treatment related events, including syncope, injurious fall, symptomatic hypotension or systolic blood pressure <90 mm Hg, and bradycardia.

RESULTS

5755 participants with 23 113 visits in the intervention group and 6382 participants with 27 868 visits in the control group were included. Mean age was 61 (standard deviation 13) years and 42.5% were women. During a median 11.6 months of follow-up, the proportion of visits at which appropriate treatment was given was higher in the intervention group than in the control group (77.8% (17 975/23 113) v 62.2% (17 328/27 868); absolute difference 15.2 percentage points (95% confidence interval (CI) 10.7 to 19.8); P<0.001; odds ratio 2.17 (95% CI 1.75 to 2.69); P<0.001). Compared with participants in the control group, those in the intervention group had a 1.6 mm Hg (95% CI -2.7 to -0.5) greater reduction in systolic blood pressure (-1.5 mm Hg v 0.3 mm Hg; P=0.006) and a 4.4 percentage point (95% CI -0.7 to 9.5) improvement in blood pressure control rate (69.0% (3415/4952) v 64.6% (3778/5845); P=0.07). Patient reported antihypertensive treatment related adverse effects were rare in both groups.

CONCLUSIONS

Use of a CDSS in primary care in China improved the provision of guideline accordant antihypertensive treatment and led to a modest reduction in blood pressure. The CDSS offers a promising approach to delivering better care for hypertension, both safely and efficiently.

The impact of communication training on the clinical care of hypertension in general practice: a cluster randomized controlled trial in China

BACKGROUND

Hypertension is one of the most common chronic diseases with a low control rate globally. The effect of communication skills training contributing to hypertension control remains uncertain. The aim of the present study was to assess the effectiveness of an educational intervention based on the Calgary-Cambridge guide in improving hypertensive management.

METHODS

A cluster randomized controlled trial enrolled 27 general practitioners (GPs) and 540 uncontrolled hypertensive patients attending 6 community health centers in Chengdu, China. GPs allocated to the intervention group were trained by an online communication course and two face-to-face workshops based on Calgary-Cambridge guides. The primary outcome was blood pressure (BP) control rates and reductions in systolic and diastolic BP from baseline to 3 months. The secondary outcome was changes in GPs' communication skills after one month, patients' knowledge and satisfaction after 3 months. Bivariate analysis and the regression model assessed whether the health provider training improved outcomes.

RESULTS

After the communication training, the BP control rate was significantly higher (57.2% vs. 37.4%, p < 0.001) in the intervention groups. Compared to the control group, there was a significant improvement in GP's communication skills (13.0 vs 17.5, p < 0.001), hypertensive patients' knowledge (18.0 vs 20.0, p < 0.001), and systolic blood pressure (139.1 vs 134.7, p < 0.001) after 3 months of follow-up. Random effects least squares regression models showed significant interactions between the intervention group and time period in the change of GP's communication skills (Parameter Estimated (PE): 0.612, CI:0.310,0.907, p = 0.006), hypertensive patient's knowledge (PE:0.233, CI: 0.098, 0.514, p < 0.001), satisfaction (PE:0.495, CI: 0.116, 0.706, p = 0.004), SBP (PE:-0.803, CI: -1.327, -0.389, p < 0.001) and DBP (PE:-0.918, CI: -1.694, -0.634, p < 0.001), from baseline to follow-up.

CONCLUSION

Communication training based on the Calgary-Cambridge guide for GPs has shown to be an efficient way in the short term to improve patient-provider communication skills and hypertension outcomes among patients with uncontrolled BPs.

TRIAL REGISTRATION

Impact of the Essential Public Health Service program on financial protection and health outcomes among hypertensive patients: A quasi-experimental study in China

BACKGROUND

The Chinese government launched the Essential Public Health Service (EPHS) program nationwide in 2009. However, prior studies have not provided clear and integrated evidence on whether the EPHS program improves health outcomes and prevents financial risks among individuals. Because hypertension is the chronic disease with the highest prevalence, this study evaluated the impact of the EPHS program among hypertensive patients to provide evidence for the progress of the program.

METHODS

A cohort of hypertensive patients was identified from the 2011-2018 China Health and Retirement Longitudinal Study (CHARLS). The outcomes assessed included hospitalization expenditure, outpatient expenditure and cardiovascular disease (heart attack and stroke). The key independent variable was whether an individual received EPHS-covered blood pressure measurements in 2013-2015. Based on the International Health Partnership+ (IHP+) common monitoring and evaluation (M&E) framework, a difference-in-differences (DID) method with propensity score matching (PSM) was used to examine the impact of the EPHS program on hypertensive patients.

RESULTS

The results showed that among hypertensive patients covered by the EPHS program, outpatient total costs/OOP costs were reduced by 29.8% and 30.8%, respectively, and hospitalization total costs/OOP costs were reduced by 34.9% and 35.6%, respectively. The EPHS program reduced the probability of heart attack and stroke among hypertensive patients by 3.5% and 2.7%, respectively. Mechanistic tests showed that the EPHS program improved health outcomes by reducing alcohol consumption and increasing physical activity, thereby further reducing health expenditure among hypertensive patients. The impacts of the EPHS program on hypertensive patients varied by age, educational attainment, residential region, and alcohol consumption status.

CONCLUSION

The EPHS program in China significantly improved health outcomes and prevented financial risks for hypertensive patients. This evidence provides a valuable reference for low- and middle-income countries with their essential public health service programs.

Inequalities in non-communicable disease management in China and progress toward universal health coverage: an analysis of nationwide household survey data from 2004 to 2018

Background

Prevention and control of non-communicable diseases (NCDs) become a policy priority in Universal Health Coverage (UHC) in China, while NCD management has never been comprehensively estimated at national and subnational levels. We aimed to assess NCD management in China nationally and in key subpopulations, investigate inequalities from multidimensions, and further examine its association with health financing and resources.

Methods

Data included were from China Chronic Disease and Risk Factors Surveillance (CCDRFS) and China Health and Nutrition Survey (CHNS). Following the WHO recommended frameworks, we selected eight NCD health service and risk management indicators and used meta-analysis to construct the composite NCD index. We explored the trends in and projections of NCD management index and indicators at national and subnational levels by using Bayesian regression models with average annual percentage change (AAPC) from 2004 to 2018 and probability of reaching the UHC target by 2030. We further conducted comprehensive inequality analyses of NCD indicators from multidimensions with patterns of changes over time using absolute difference and relative ratio. Finally, we quantified the associations between NCD management performance with health financing and resources using stochastic frontier analysis.

Findings

In China, the NCD management index increased slowly from 62.0% (95% CI 36.0 to 84.0) in 2004 to 64.3% (95% CI 44.0 to 82.2) in 2018, with lagging performance being observed in prevention domain (AAPC -0.1%, 95% CrI -1.0 to 0.8). And all management indicators presented low probabilities of accomplishing 2030 targets in China. Notably, based on subnational analysis, diverse tendency and magnitude of inequalities in multiple NCD indicators were identified with widening gaps between genders (non-overweight, diabetes treatment), age groups (non-use of tobacco), urban-rural areas (non-use of alcohol, non-use of tobacco), regions (sufficient physical activity), and wealth quintiles (non-overweight, sufficient physical activity). Additionally, it was observed that compared with urban area, rural area had constantly lower health resources and presented 2.2% lower NCD management performance in 2018. Importantly, we found that health financing and resources especially distributed in primary health care (PHC) facilities were closely and positively associated with NCD management performance. A 1000 yuan increase of government health expenditure (GHE) per capita and a 10 increase of medical beds per 1000 capita in PHC facilities were associated with a 4.0% (95% CI 2.0 to 6.0) and 6.8% (95% CI 0.2 to 13.5) increase of NCD management index, respectively.

Interpretation

The progress towards NCD management is slow at national level and in key subpopulations in China, with great challenges of existing and widening inequalities between genders, age groups, urban-rural areas, regions and socioeconomic groups. Rural and old people were still vulnerable populations who were lagging behind in NCD prevention and control. Optimising resource allocation by strengthening PHC especially in rural area, developing tailor-made programmes targeting specific populations such as old individuals, simultaneously integrating gender, education, and economic interventions to reduce inequalities should be prioritised to help China tackle NCDs during the progress towards UHC.

A tryst of 'blood pressure control- sex- comorbidities': the odyssey of basic public health services in Yunnan in quest for truth

BACKGROUND

The Basic Public Health Service (BPHS), a recently announced free healthcare program, aims to combat the most prevalent Noncommunicable Disease-"Hypertension" (HTN)-and its risk factors on a nationwide scale. In China, there is a rife that HTN less impacts women during their lifetime. We, therefore, aimed to evaluate the sex disparity in hypertension patients with comorbidities among south-west Chinese and the contribution of BPHS to address that concern.

METHODS

We have opted for a multistage stratified random sampling method to enroll hypertensive patients of 35 years and older, divided them into BPHS and non-BPHS groups. We assessed the sex disparity in HTN patients with four major comorbidities- Dyslipidemia, Diabetes Mellitus (DM), Cardiovascular Disease (CVD), and Chronic Kidney Disease (CKD), and descriptive data were compiled. Odds ratios from logistic regression models estimated the effectiveness of BPHS in the management of HTN with comorbidities.

RESULTS

Among 1521 hypertensive patients,1011(66.5%) were managed in the BPHS group. The proportion of patients who had at least one comorbidity was 70.7% (95% confidence interval [CI]: 66.3-76.8%), patients aged 65 years and older were more likely to have coexisting comorbidities. Participants who received the BPHS showed significant blood pressure (BP) control with two comorbidities (odds ratio [OR] = 2.414, 95% CI: 1.276-4.570), three or more (OR = 5.500, 95%CI: 1.174-25.756). Patients with dyslipidemia and DM also benefited from BPHS in controlling BP (OR = 2.169, 95% CI: 1.430-3.289) and (OR = 2.785, 95%CI: 1.242-6.246), respectively. In certain high-income urban survey centers, there was sex differences in the HTN management provided by BPHS, with men having better BP control rates than women.

CONCLUSIONS

Perhaps this is the first study in China to succinctly show the effectiveness and sex disparity regarding "management of hypertensive comorbidities". This supports that the BPHS program plays a pivotal role in controlling BP, therefore should recommend the national healthcare system to give women a foremost priority in BPHS, especially to those from low-socioeconomic and low-scientific literacy regions.

Universal health coverage in China part 1: progress and gaps

Over the past 2 decades, China has made remarkable progress in health-care service coverage, especially in the areas of reproductive, maternal, newborn, and child health, infectious diseases, and service capacity and access. In these areas, coverage is comparable to those in high-income countries. Inequalities of service coverage in these areas have been reduced. However, there remain large gaps in the service coverage of chronic diseases. There has been little progress in controlling risk factors of chronic diseases in the past 10 years. Service coverage for most chronic conditions is lower than in high-income countries. Moreover, China has disproportionately high incidences of catastrophic health expenditure compared with countries with similar economic development. This paper comprehensively evaluates China's progress towards universal health coverage by identifying the achievements and gaps in service coverage and financial risk protection that are crucial to achieve universal health coverage goals by 2030.
