The Current Landscape of Congenital Heart Surgery in Northern China: A Geographic and Population-Based Analysis

Improving long-term care and outcomes of congenital heart disease: fulfilling the promise of a healthy life

Advances in the prevention, diagnosis, and treatment for congenital heart disease (CHD), the most common birth defect in China, have drastically improved survival for individuals with the disease. However, China's current health system is not well prepared to manage the growing population of people with CHD and their complex medical needs, which range from early detection of the condition and intervention for physical, neurodevelopmental, and psychosocial impairment, to long-term management of major complications and chronic health problems. Health disparities caused by long-standing regional differences in access to care pose challenges when major complications such as pulmonary hypertension arise, and when individuals with complex CHD become pregnant and give birth. Currently, no data sources track neonates, children, adolescents, and adults with CHD in China and delineate their clinical characteristics and use of health resources. This scarcity of data should warrant attention from the Chinese Government and relevant specialists in the field. In the third paper of the Series on CHD in China, we summarise key literature and current data to identify knowledge gaps and call for concerted efforts by the government, hospitals, clinicians, industries, and charitable organisations to develop an actionable, lifelong framework of congenital cardiac care that is accessible and affordable for all individuals with CHD.

An interactive geographic information system to inform optimal locations for healthcare services

Large health datasets can provide evidence for the equitable allocation of healthcare resources and access to care. Geographic information systems (GIS) can help to present this data in a useful way, aiding in health service delivery. An interactive GIS was developed for the adult congenital heart disease service (ACHD) in New South Wales, Australia to demonstrate its feasibility for health service planning. Datasets describing geographic boundaries, area-level demographics, hospital driving times, and the current ACHD patient population were collected, linked, and displayed in an interactive clinic planning tool. The current ACHD service locations were mapped, and tools to compare current and potential locations were provided. Three locations for new clinics in rural areas were selected to demonstrate the application. Introducing new clinics changed the number of rural patients within a 1-hour drive of their nearest clinic from 44·38% to 55.07% (79 patients) and reduced the average driving time from rural areas to the nearest clinic from 2·4 hours to 1·8 hours. The longest driving time was changed from 10·9 hours to 8·9 hours. A de-identified public version of the GIS clinic planning tool is deployed at https://cbdrh.shinyapps.io/ACHD_Dashboard/. This application demonstrates how a freely available and interactive GIS can be used to aid in health service planning. In the context of ACHD, GIS research has shown that adherence to best practice care is impacted by patients' accessibility to specialist services. This project builds on this research by providing opensource tools to build more accessible healthcare services.

Inpatient costs of congenital heart surgery in China: results from the National Centre for Cardiovascular Diseases

Background

Economic data on congenital heart disease (CHD) in China are scarce. Therefore, this study aimed to explore the inpatient costs of congenital heart surgery and related healthcare policies from a hospital perspective.

Method

We used data from the Chinese Database for Congenital Heart Surgery (CDCHS) to prospectively analyse the inpatient costs of congenital heart surgery from May 2018 to December 2020. The total expenditure was divided into 11 columns (medications, imaging, consumable items, surgery, medical cares, laboratory tests, therapy, examinations, medical services, accommodations, and others), and explored according to the Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery (STAT) category, year, different age group, and CHD complexity. Authority economic data (index for gross domestic product [GDP], GDP per capita, per capita disposable income and average annual exchange rate of 2020 Chinese Yuan against US dollar) were accessed via the National Bureau of Statistics of China to better describe the burden. In addition, potential factors contributing to the costs were also investigated by using generalised linear model.

Findings

All values are presented in 2020 Chinese Yuan (¥). A total of 6568 hospitalisations were enrolled. The median of overall total expenditure was ¥64,900 (≈9409 US Dollar [USD], interquartile range [IQR]: ¥35,819), with the lowest in STAT 1 (¥57,014 ≈ 8266 USD, [IQR]: ¥16,774) and the highest in STAT 5 (¥194,862 ≈ 28,251 USD, [IQR]: ¥130,010). The median costs during the 2018 to 2020 period were ¥62,014 (≈8991 USD, [IQR]: ¥32,628), ¥64,846 (≈9401 USD, [IQR]: ¥34,469) and ¥67,867 (≈9839 USD, [IQR]: ¥41,496). Regarding to age, the median costs were highest in the ≤1 month group (¥144,380 ≈ 20,932 USD, [IQR]: ¥92,584). Age, STAT category, emergency, genetic syndrome, delay sternal closure, mechanical ventilation time, and complications were significantly contributed to the inpatient costs.

Interpretation

For the first time, the inpatient costs of congenital heart surgery in China are delineated in detail. According to the results, CHD treatment has achieved significant progress in China, but it still causes substantial economic burden to both families and society. In addition, ascending trend of the inpatient costs was observed during the period of 2018-2020, and the neonatal was revealed to be the most challenging group.

Funding

This study was supported by the CAMS Innovation Fund for Medical Sciences (CIFMS,2020-I2M-C&T-A-009), Capital Health Research and Development of Special Fund (2022-1-4032), and The City University of Hong Kong New Research Initiatives/Infrastructure Support from Central (APRC, 9610589).

Two approaches for newborns with critical congenital heart disease: a comparative study

BACKGROUND

Prenatal diagnosis and planned peripartum care is an unexplored concept in China. This study aimed to evaluate the effects of the "prenatal diagnosis and postnatal treatment integrated model" for newborns with critical congenital heart disease.

METHODS

The medical records of neonates (≤ 28 days) admitted to Fuwai Hospital were reviewed retrospectively from January 2019 to December 2020. The patients were divided into "prenatal diagnosis and postnatal treatment integrated group" (n = 47) and "non-integrated group" (n = 69).

RESULTS

The age of admission to the hospital and the age at surgery were earlier in the integrated group than in the non-integrated group (5.2 ± 7.2 days vs. 11.8 ± 8.0 days, P < 0.001; 11.9 ± 7.0 days vs. 16.5 ± 7.7 days, P = 0.001, respectively). The weight at surgery also was lower in the integrated group than in the non-integrated group (3.3 ± 0.4 kg vs. 3.6 ± 0.6 kg, P = 0.010). Longer postoperative recovery time was needed in the integrated group, with a median mechanical ventilation time of 97 h (interquartile range 51-259 h) vs. 69 h (29-168 h) (P = 0.030) and with intensive care unit time of 13.0 days (8.0-21.0 days) vs. 9.0 days (4.5-16.0 days) (P = 0.048). No significant difference was observed in the all-cause mortality (2.1 vs. 8.7%, P = 0.238), but it was significantly lower in the integrated group for transposition of the great arteries (0 vs. 18.8%, log rank P = 0.032).

CONCLUSIONS

The prenatal diagnosis and postnatal treatment integrated model could significantly shorten the diagnosis and hospitalization interval of newborns, and surgical intervention could be performed with a lower risk of death, especially for transposition of the great arteries.
