Spatial features
From the Administrative district chart of Chengdu city, district 1, 2, 3, 4, 5 are regarded as downtown zone, 6,7.8,9,10,11 are regarded as the second layer of the city , district 12, 13, 14, 15, 16, 17, 18, 19, 20 are regarded as the third layer of the city.
The figures show that the tendency of visits to hospitals is downtown zone > the second layer of the city > the third layer of the city and shows a high-high density tendency. However, the visits in CHCs tend to be random, and there is no autocorrelation in different districts.
The tendency of visits to hospitals reflects the medical level and residents’ preferences. The downtown zone, especially districts 2 and 4, has the most recognized large hospitals in Chengdu. The centralization tendency is significant from 2015-2020, despite any family doctor contract policy.
The high-high density implies that some medical alliances have a positive effect on promoting residents’ confidence level, and
The second layer of the city has the most benefit (West China hospital medical alliances in districts 6, 7.8, 9, 10, and 11). However, perhaps due to some traffic distance, some third layer of the city (districts 12 and 19) has little chance to visit the high-level hospital but to visit the hospital locally.
For primary care, the figure shows that there is no CHC brand that draws residents’ preferences. On the one hand, it has a positive meaning that residents choose their primary care locally. On the other hand, the whole system—the hierarchical medical system referred to by the CHCs—is not well built. In fact, to strengthen primary care, the Chinese government set up a 15-minute health care square, aiming “Minor illness does not leave the village, serious illness does not leave the county” [
18]. However, patients had a strong preference for free choice between general practitioners and specialists, and the spatial feature had its own feature. There is no significance of spatial autocorrelation in 2015-2020, which means that it is randomly chosen by residents, and a high-high density trend appears in hospital visits. District4 has achieved a good demonstration role since it was officially awarded the title of the first batch of "National Chronic Disease Comprehensive Prevention and Control Demonstration Zone" in 2012. In recent years, District 4 has given full play to the government's leading role in the prevention and control of chronic diseases, striving to build a professional collaboration system for chronic disease prevention and treatment, actively promoting the national healthy lifestyle and other characteristic practices and experiences, and establishing multidepartment and street-level comprehensive prevention and control linkage mechanisms for chronic diseases. Further research revealed that grassroots hospitals may have achieved innovation and breakthroughs in policy implementation, talent introduction, diagnosis and treatment technology and innovation, driving the improvement of the overall technical level of grassroots hospitals.
Additionally, in hospital visits, West China hospital, which represents the high level in the country located in district 2 and district 4, especially in district 13, may be contributed by the Chengdu (main district)-Jianyan highway. The convenience brings more patients directly to Chengdu city, leading to spatial autocorrelation in Chengdu city.
Both hospital and CHC visits show spatial autocorrelation and high-high density. On the one hand, it is a positive reflection that both hospitals and CHCs have their own brand influence for residents; on the other hand, hospitals may still “siphon” patients around the areas, which reveals that they are not good omen to build orderly visits and hierarchical medical systems.
Policy suggestions
Strengthen the coordination between CHC institutions and hospitals by the path of FDs
Fragmented delivery and the capacity gap between the hospital and CHC suppressed the development of primary care. The family doctor contract reveals an ideal path to accomplish the above goal.
hospital-centered fragmented delivery [
19] were to prevail—population health outcomes would suffer; health-care expenditures would escalate, with patients bearing increasing costs; and a two-tiered system would emerge in which access and quality of care are decided by ability to pay. We then propose an alternative pathway that includes the reform of public hospitals to pursue the public interest and be more accountable, with public hospitals as the benchmarks against which private hospitals would have to compete, with performance-based purchasing, and with population-based capitation payment to catalyze coordinated care. Any decision to further expand the for-profit private hospital market should not be made without objective assessment of its effect on China's health-policy goals.
To establish a medical alliance or integrated delivery system, as encouraged by the State Council of China and recommended globally, CHC institutions and hospitals need to closely coordinate their functions. In addition to vertical technical support provided by hospitals to CHC institutions within the same catchment areas, deeper coordination between them should be implemented to best suit local contexts, with integrated systems for staff training, medication supply, and health information technology support.
However, the most significant issue is to draw the incentive during the collaboration among hospitals to the CHC. CHC providers are in a central position to coordinate a person's care needs, from prevention to disease management to curative care. There are several barriers to overcome before this aspiration becomes a reality. The concept of continuity of care entails several dimensions. First, relational continuity encourages patients to enter into contractual arrangements with family doctors. However, China does not make it compulsory for patients to see CHC providers as their first contact. As the first step toward building a gatekeeping system, the government has introduced a family doctor registration policy by which each resident would be registered with a team of family doctors. Moreover, there is a general lack of patient awareness about the importance of continuity of care. In a study in Beijing, patients had a strong preference for free choice between general practitioners and specialists. Thus, there is an essential way to build FDs where CHC institutions and hospitals participate together. By the path of FDs, CHC institutions and hospitals both sign contrast with the residents and take responsibility for the residents.
Reform the payment by integrating CHC institutions and hospitals by the path of FDs
In 2015, the Chinese government issued guidelines for building a so-called tiered health-care delivery system whereby each level of health-care facility (tertiary, secondary, and primary) would deliver care according to their designated functions; care across the levels was to be integrated and coordinated with bidirectional referral mechanisms through establishing medical alliance or integrated systems. These pilot implementations have been slow and hindered by several factors. First, as hospitals and CHC institutions are still primarily paid by fee-for-service, they compete for patients and have few incentives to coordinate. Second, the social health insurance programme, which covers 96% of the population, 4 reimburses patients wherever they seek care without referral; thus, there is generally no defined coordinating process. In addition, reimbursement for hospital care is more generous than that for care at CHC institutions considering the ceiling and therefore encourages patients to bypass CHC facilities, making it difficult for CHC providers to function as gatekeepers. Third, electronic patient records are not integrated and are seldom shared between CHC institutions and hospitals. 56 Therefore, even though partnerships between hospitals and CHC institutions are encouraged and have formed in many cities, 57 the association remains loose.
Within CHC institutions, the National Basic Public Health Service Program could in theory provide a basis for integration between clinical care and public health services. However, the integration was suboptimal in reality for two reasons. First, financing for public health services and clinical care of the same CHC institutions came from different sources. Although the government directly funds a defined package of public health services, clinical care is funded by social health insurance. Second, there is almost no coordination in monitoring, performance measurement, or management between the two programs. Thus, as we observed as researchers and practitioners, there is little workflow interaction or information sharing between the programs. For instance, in hypertension management visits under the National Basic Public Health Service Program, patients can have blood pressure measurements and lifestyle consultations by public health workers but cannot obtain prescriptions of antihypertensive drugs without attending clinics. Additionally, resident health records of public health services and medical records of clinical care are kept by two separate information systems even for the same visit of the same patient, without linkage between them. Poor care coordination is a hindrance, particularly to managing noncommunicable diseases. institutions, the opportunity to integrate clinical care and public health services is severely limited. Thus, by providing the FDs that the CHC institutions and hospitals both involved, the payment should be integrated.
Either public or private packages could be provided to meet the devise health needs of citizens.
Enhance the quality of training for the new and current CHC workforce in the path of FDs
The State Council issued guidance on the reform and development of training and incentive mechanisms for CHC physicians. Despite this guidance, a comprehensive range of detailed recommendations on the quality of training are needed to address the wide variation in standards of medical school education [
20,
21]. Without the family doctor contract mode, the concept of patient-centered care is difficult to teach during college training and GP resident training periods. The curriculum needs to be promoted without teaching GP residents to take responsibility for FDs.
In CHC staff training, it is necessary to tailor the clinical practice guidelines to the CHC environment and contain feasible and affordable suggestions, including the integration of patient-centered views with patient goals [
22,
23]. These guidelines should focus on the use of cost-effective diagnostic methods and treatment measures [
24‐
27]. China will benefit from an institution that supervises the formulation of disease management protocols and involves CHC providers, which in turn can provide information for the training of CHC doctors in appropriate and contextual use. FDs provide GPs and specialist training with a common goal for person-centered care.
Integrate in referral system in tern of path of FDs
The role of family physicians in referring patients to specialists diminishes, possibly because the current referral system is imperfect [
28]. One study criticized two-way referrals for transferring patients only from community health centers to hospitals but not from hospitals to community health centers. There has not been enough focus on increasing the attractiveness of community health centers, and there is an urgent need for a convenient and effective referral system [
23,
29,
30]. It is also necessary to increase the motivation of secondary and tertiary hospitals to admit patients from community health centers. Surprisingly, we did not find a positive effect of first exposure to CHC on referral through CHC. In other words, although contracting with FD patients was positively associated with referral behavior, it was not associated with first contact with CHC patients. It is worth exploring how functional development affects recommendation behavior in further research. However, other researchers have reported similar results. Recent research suggests that gatekeeping may not be associated with changes in the coordination of referral care, although it is associated with a wider range of conditions managed by GPs at first contact. In addition, an inverse association was found, suggesting that CHC gatekeeping can reduce hospitalizations. Although we found that FDs have a positive effect on first contact and referral through CHC, the mechanisms by which FDs affect referral behavior remain unclear. The cooperation of the feature development team may bring about positive and negative mechanisms that influence recommendation behavior.
