Abstract
Objectives Reconstructing the primary healthcare system is the focus of the new round of Chinese health reform. Nevertheless, there have been few studies focusing on the strengthening of primary healthcare in Chinese health system.
Design This study was a longitudinal observational study.
Primary and secondary outcome measures The data of this study came from China Health Statistical Yearbook (2009–2018). We evaluated the development of primary healthcare based on the absolute values of health resources allocation and health service provision and evaluated the status of primary healthcare throughout the health system based on the composition ratios of the indicators across the health system. The Cochran-Armitage trend test and linear trend test were used to identify the indicators’ trends over time.
Results From 2009 to 2018, the amounts of health resources allocation and health service provision of Chinese primary healthcare institutions showed a significant upward trend (p<0.001). However, compared with the indicators in 2009, excepting that the proportion of grants from the government in the whole health system has an upward trend, the proportions of other indicators had an escalating trend in 2018 by 3.66% for practicing (assistant) physicians, by 2.69% for nurses, by 3.99% for total revenues, by 5.87% for beds, by 8.39% for outpatient visits.
Conclusion The primary healthcare system has developed rapidly, but its development speed lagged behind the entire health system, resulting in the weakening of its actual functions, which is not in line with the goal of health reform. The government should be more aware of the importance of primary healthcare at all levels of local governments and ensure adequate financial input.

Strengths and limitations of this study
This study was a longitudinal observational study based on China Health Statistics Yearbook (2009–2018), which provided information on health resources and health services of different kinds of medical institutions in China.
This study was the first to use the Cochran-Armitage trend test and linear trend test to examine trends in health resources allocation and health service provision, which somewhat increased the statistical validity of the results.
Due to the limited data provided by the Yearbook, we could not analyse the development of primary healthcare institutions (PHIs) before 2009. Second, due to the limited data provided by the Yearbooks, we could only analyse the development of primary healthcare (PHC) based on health resources allocation and health service provision. Other important evaluation dimensions, such as the health service quality and the development equity of PHC and regional heterogeneity, were not analysed, which could limit the overall understanding of primary healthcare development in China.
In addition, the data used in this study were panel data, so that we could only carry out descriptive and trend analysis. Therefore, it was difficult for us to make an in-depth analysis and comparison.
Introduction
Primary healthcare (PHC) is the key to achieving the goal of ‘health for all’.1Chinese government had established a relatively complete primary healthcare system in the late 1950s,2 which has been promoted and introduced by WHO to other countries as a model.3 However, after 1978, the primary healthcare system, which mainly relied on government funding to maintain normal operation, collapsed almost overnight.4 5 At the same time, some problems, such as lacking adequate health resources, inadequate staff capacity, unregulated health services provision, outdated medical facilities, low levels of trust among the population and so on, have hindered the development of primary healthcare institutions (PHIs), resulting in their health service provision at a low level for a long time.6–10 Based on the reasons above, PHIs have become the least developing and most vulnerable part of the health system in China, seriously impeding the realisation of the goal of ‘healthcare for all’. Previous studies focused on the impact of socioeconomic status on individual health status,11 12 but fewer researches on the impact of health resources allocation and health service provision on individual health outcomes.
In response to the above problems, the government began to launch a new round of health reform in 2009,13–15 aiming at optimising the distribution of health resources, strengthening the capacity of primary care and guiding residents to seek medical treatment from PHIs.16 17 Reconstructing the PHC system is the focus of this reform,13 15 and it is also the key to realising the reform goal. In the first 3 years from 2009, the government health investment amounted to about CNY 1409.9 billion (US$ 206 billion), and 44% of the funds were allocated for PHIs.18 In addition, the Chinese Government is actively promoting the construction of PHC workforce with general practitioners at its core, standardising service programmes including 17 basic public health services, promoting family doctor contracting services, improving the multilevel medical security system supported by the basic medical insurance and other forms of supplementary insurances, integrating the sharing of regional health resources, and other improvements to the PHC system.14 19 20 Moreover, in 2019, China has implemented Basic Healthcare and Health Promotion Law,21 which elevated the policy of strengthening PHC to the legal level and opened up new opportunities for the development of PHIs. Therefore, it is timely and particularly important to evaluate the current situation of the development of PHC and find the problems existing in the PHC or sum up successful experiences in China.
At present, there have been some studies on PHC in China, but there are more deficiencies. First, the evaluation perspective is relatively single, most researchers evaluate from a single aspect of health resources allocation or service provision,22 lacking a combination of the two aspects. Second, most studies were based on specific regions or groups of the population and lacked a comprehensive national evaluation.23 24 In addition, most of the existing studies used cross-sectional data or only intercept short-term data for effect evaluation,25 resulting in certain problems such as the ineffectiveness of policy construction due to the insufficient time span of the data, which weakened the accuracy of the research results to a certain extent. Therefore, it is not clear whether the role of primary healthcare in the overall health system is strengthened, which is the core goal of this round of health reform in China. Health resources allocation and health service provision are the two core contents of health service research. According to the resource allocation theory, the rational allocation of health resources and the adequate guarantee of health services are the crucial basis for the normal operation of the whole health system.26 Therefore, analysing PHC’s constituent ratio of health resources allocation and health service provision in the whole health system is the main approach to analysing its role in the whole health system.
Therefore, based on the Chinese health statistics data in the past 10 years, the trend test27 28 was being used to analyse the changing tendency of various indicators of PHC system construction since the health reform. This study evaluated the development of the PHC system via analysing the changing trend of health resources and health service quantities and evaluated the role of primary healthcare in the whole health system by analysing the proportion of health resources allocation and health service provision in the whole health system. This study was of great practical significance to evaluate the effect of the construction of PHC effectively and to summarise the construction experience and existing problems, adjusting the relevant policies and measures of health reform, promoting high-quality development of medical care, accelerating the realisation of the goal of reconstructing the PHC system.
Methods
Study design and data source
This study was a longitudinal observational study based on China Health Statistics Yearbook (2009–2018), which provided information on health resources and health services of different kinds of medical institutions in China. In order to assess whether Chinese health resources were tilted towards PHIs and whether the service quantity of PHIs has been increased, we analysed the dynamic changes in the absolute value and the constituent ratio of health resources allocation and health service provision in PHIs from 2009 to 2018.
Indicators and definitions
In this study, the definition of PHIs refers to the statistical calibre of the China Health Statistics Yearbook. In China, PHIs include community health service centres (stations), township health centres, village clinics, outpatient departments, clinics, infirmaries and nursing stations. The main indicators of this study are health resources allocation and health service provision. Health resources include human resources, financial resources and material resources. Human resources include the number of health workers, practicing (assistant) physicians, nurses and pharmacists. Financial resources include total revenues, grants from the government and incomes from charges for services. Material resources include a total number of equipment at or above CNY 10 000, building areas and the total number of beds. Health service provision includes an annual number of outpatient visits and inpatient care. The details about the indicators are shown in online supplemental appendix 1.

Statistical analysis
The trend test is used to count whether there is some trend in the change of a certain indicator with the change of the year and to test whether this trend is statistically significant. In this study, the linear regression test and the Cochran-Armitage trend test were used to test the trend of relevant indicators,28 so as to ensure the robustness of the results. The more detail about the linear regression test and the Cochran-Armitage trend test are shown in online supplemental appendix 2. We used the absolute value of each indicator to analyse the development of PHIs and the linear regression analysis to test the trend of absolute values over time. When the regression coefficient β was positive, the absolute value of each indicator had an upward trend, on the contrary, when β was negative, the absolute value of each indicator showed a downward trend. We evaluated the status of primary healthcare throughout the health system based on the composition ratio of the indicators across the health system and used the Cochran-Armitage trend test to examine the trend of composition ratio for each indicator over time. The Z value was positive, which means that the composition ratio of each indicator has shown an upward trend, oppositely, the Z value was negative, which means that the composition ratio of each indicator presented a downward trend.
Supplemental material
In this study, analyses were performed using SAS V.9.2 (SAS, Cary, North Carolina). All statistical tests were two tailed, and a p value <0.05 was considered to be statistically significant.
Results
The dynamic changes in the quantities of the health resources allocation and health service provision in all medical institutions and PHIs in China
The quantities of human resources
From 2009 to 2018, the quantities of human resources in China showed a significant dynamic upward trend over time, which were statistically significant (p<0.001). Compared with the human resources in 2009, the quantities of the total health workers, practicing (assistant) physicians, nurses and pharmacists in 2018 have increased by 58.07%, 54.87%, 120.97% and 36.79%, respectively. For PHIs, the amounts of health resources had an escalating trend, but the rate of increases were slower than the whole health system, by 25.78% for the total health workers, by 40.63% for practicing (assistant) physicians, by 101.86% for nurses and by 23.21% for pharmacists (tables 1 and 2).

The quantities of financial resources
Compared with the financial resources in 2009, for PHIs, besides grants from the government had a greater increase than the one for all medical institutions (628.51% vs 354.18%) in 2018, the other indicators’ rates of increases were slower than in all medical institutions, for total revenues (173.26% vs 246.56%) and for incomes from charges for services (93.70% vs 223.39%). (tables 1 and 2)
The quantities of material resources
From 2009 to 2018, the quantities of all indicators both in all medical institutions and PHIs had an apparent upward trend (p<0.001). However, for PHIs, all indicators’ rates of increases were slower than in all medical institutions, for beds (45.11% vs 90.28%), building areas (37.85% vs 81.76%) and the total number of equipment at or above CNY, 10 000 (140.30% vs 189.30%) (tables 1 and 2).
The quantities of service provision
From 2009 to 2018, in addition to the number of inpatient care in PHIs, the quantities of the indicators for service provision in China had an upward trend (p<0.001). The quantities of outpatient visits and inpatient care significantly increased by 53.80% and 92.01% for Chinese all medical institutions from 2009 to 2018. Compared with the rate of increases with all medical institutions, PHIs have grown more slowly, whose growth rate was 32.52% and 6.44% (tables 1 and 2).
Proportions of health resources allocation and health service provision by PHIs
Figure 1A shows the trend of human resource allocation in Chinese PHIs from 2009 to 2018. The results indicated that the proportion of health workers had decreased year by year, which was statistically significant (p<0.001). The proportion of the number of health workers in the whole health system declined from 40.51% in 2009 to 32.23% in 2018. Among them, practicing (assistant) physicians declined from 39.84% in 2009 to 36.18% in 2018, nurses declined from 22.77% in 2009 to 20.80% in 2018, and pharmacists declined from 34.85% in 2009 to 31.39% in 2018.

(C) Changes in the percentage of material resources in primary healthcare institutions, 2009–2018. (D) Changes in the percentage of health service provision in primary healthcare institutions, 2009–2018.
In the allocation of financial resources, the proportion of grants from the government has increased by about 10 percentage points, increasing from 22.33% in 2009 to 32.60% in 2018. On the contrary, the proportions of total revenues and incomes from charges for services had a significant down, which were a decrease of 3.99% and 7.37% in these two departments, respectively, compared with proportions in 2009 (figure 1B).
As to 2018, among material resources, the proportions of the total number of equipment at or above CNY 10 000, building areas and the total number of beds had decreased by nearly 2, 8 and 6 percentage points, respectively (figure 1C).
The dynamic change of the proportion of service provision in PHIs from 2009 to 2018 is shown in figure 1D. The number of outpatient visits in PHIs dropped from 60.63% in 2009 to 52.24% in 2018, a decrease of approximately 8 percentage points. The proportion of inpatient care decreased from 31.01% in 2009 to 17.19% in 2018, a decline of approximately 13 percentage points. All (p<0.001) showed a significant downward trend.
The results of all the indicators’ trend tests are shown in online supplemental appendix 3.
Discussion
On the occasion of the 10th anniversary of Chinese health reform, there have been some studies expounding the effectiveness of health reform,20 24 29 30 such as Meng and colleagues, based on the Chinese Health Statistics Yearbook, using descriptive analysis to highlight changes in government and social health expenditure and changes in unmet health needs and disparities in maternal and infant mortality as the health output and outcome.14 This study was the first to use the trend test to analyse the development of PHC in China from two inter-related aspects: health resources allocation and health service provision. With the rapid development of China’s health system in the past 10 years, the absolute value of health resources allocation and health service provision of the PHIs has increased significantly, but the rate of increases of PHIs was slower than the whole health system. At the same time, the proportion of health resources allocation and health service provision of the PHIs in the whole health system has continued to decline, which suggested that the Chinese PHIs has made some progress after the health reform, but its development rate was slow, lagging behind the whole health system, which indicated that the role of PHC has been indeed weakened in China.
From 2009 to 2018, a total amount of health resources allocation and health service provision have been increasing of PHIs, and the hardware conditions of diagnosis and treatment services gradually improved at the same time, which was similar to the findings of Xu et al31 and Zhang et al.32 In addition, under the regulation of the policy to strengthen PHC, the Chinese government has continued to increase financial investment in PHIs, and the proportion of grants from the government of PHIs has an apparent increase, from 20.33% to 32.60%, which was consistent with the existing studies.33 34 These measures have effectively improved the hardware conditions and diagnosis and treatment environment of PHIs in a short period of time, including the reconstruction and expansion of business rooms, the purchase of equipment, the training or introduction of talented health workers.
It is worth noting that from the dynamic changes of the constituent ratio of health resources allocation and health service provision for PHIs, except for the proportion of grants from the government, other indicators all have decreased in varying degrees, which indicated that with the change of time, the basic conditions and service output of PHC are constantly improving, but its development speed is lower than that of the whole health system. To some extent, this study showed that the development of Chinese PHC might have lagged behind the whole health system in the past decade, which had not yet reached the goal of health reform to strengthen the role of PHC. The reasons for this result may be multifaceted.
First, in spite that the Chinese central government has formulated a series of policies and measures to promote the development of primary healthcare,14 35–37 the implementation of the policies was mainly done by local governments.25 The implementation of policies was inevitably accompanied by the allocation of health resources. Due to lacking awareness of the importance of primary healthcare among local governments,5 38 39 they might have allocated more resources to general hospitals and specialist hospitals. Second, the current power structure inside the medical industries is more likely to elicit a trend that the general hospitals possess more power of discourse than the PHIs in the same region. Third, previous studies have consistently concluded that the development of primary healthcare lacked sufficient financial support in China,8 40 but how much financial investment is sufficient has been a lack of research. Fourth, compared with hospitals, PHIs had lower remuneration and limited career development prospects in China, which led to the extremely low attraction for excellent health professionals.14 In this study, the proportion of health workers in PHIs in the whole health system has decreased year by year, from 40.51% in 2009 to 32.23% in 2018, which was consistent with the results of Zhong et al.41 Moreover, at present, the strengthening PHC measures implemented put too much emphasis on the standardisation and the improvement of hardware conditions of PHIs in China,30 42–44 while ignoring the improvement of PHIs service capacity and the construction of supporting mechanisms, so that the trust of residents in PHIs has not been effectively improved. As a result, the number of outpatient visits and inpatient care in PHIs decreased at an average annual rate of about 0.8% and 1.4%, respectively, resulting in reducing the incomes from charges for services of PHIs and aggravating the shortage of health funds, then forming a vicious circle of ‘the development backwardness of primary healthcare-low attractiveness for patients-more backward of primary healthcare’.
The strength of this study was that this study was the first to use the trend test to examine trends in health resources allocation and health service provision, which somewhat increased the statistical validity of the results. Second, the existing studies’ evaluation perspective was scattered, analysing the effectiveness of the health reform more at a microlevel, such as the expenditure on health costs and the improvement of the health status of the population. This study used longitudinal data to evaluate the development of PHC in China at a macrolevel, which could improve the understanding of scholars and policymakers at home and abroad about the practical experience and existing problems in building the Chinese PHC system. Moreover, this study has strong implications for low-income and middle-income countries, particularly those with social systems compatible with China, strengthening their decision-making on PHC planning, health resources allocation and health service provision.
This study also had some limitations. First, some of the indicators were introduced to the yearbooks after the health reform in 2009, and few of them were aggregated at a provincial level. Therefore, due to the limited data provided by the Yearbook, we could not analyse the development of PHIs before 2009. Second, due to the limited data provided by the Yearbooks, we could only analyse the development of PHC based on health resources allocation and health service provision. Other important evaluation dimensions, such as the health service quality and the development equity of PHC, and regional heterogeneity were not analysed, which could limit the overall understanding of primary healthcare development in China. In addition, the data we used came from the Yearbook, which was panel data, so that we could only carry out descriptive and trend analysis and was difficult to make a more in-depth analysis and comparison. It was also impossible for us to analyse how much of the changing trend in the development of PHC could be attributed to the health reform.
Conclusions
Based on continuous longitudinal data provided by China Health Statistical Yearbook from 2009 to 2018, this study found that the absolute values of health resources allocation and health service provision of the PHIs have increased significantly, but the proportions of health resources allocation and health service provision of the PHIs in the whole health system have continued to decline, which suggested that the PHC system developed rapidly, but its development speed lagged behind the whole health system, resulting in the weakening of its actual functions, which is not in line with the goal of health reform. All these indicate that in the next stage of the health reform, the Chinese government should improve the awareness of the importance of PHC at all levels of governments, mobilise their enthusiasm and strengthen their responsibility to optimise health resources allocation. Second, it is also crucial to set up special funds for PHC to ensure that the relevant funds, equipment, talents and other resources are directly sunk to PHIs, so as to enhance PHIs’ capacity of services and guide residents to seek medical treatment from PHIs. Additionally, health education and reasonable payment methods of medical insurance should be introduced to change residents’ health-seeking patterns and guide residents to use primary healthcare services.
