Health Technology Assessment in China's Health Care Sector: Development and Applications.

China's health system is facing severe challenges from social transition and the double burden of population aging and non-communicable diseases. Addressing the tension between the public's increasing demand for health services and the limited availability of medical resources has become a critical issue for health care policymakers and medical insurance fund administrators. In promoting its medical insurance system reform, China is actively developing health technology assessment (HTA) with principles and applications adapted to the Chinese context. This study aims to analyze the evolution of HTA in China with a focus on context, actors, process, content, and challenges encountered through applying a modified verson of Walt and Gilson's policy triangle framework. Currently, HTA plays an indispensable part in the reform of China's health care and medical insurance system, especially in the formulation and adjustment of the National Reimbursement Drug List (NRDL). While HTA is increasingly used in China, there remain challenges, such as the slow development of HTA related disciplines, lack of an independent national HTA authority, and limited scope in the use of HTA. Despite the identified challenges, HTA has the potential to support a wide range of applications in China's health care sector, building on the progress achieved over the last three decades.

[Study on establishing a methodology of comprehensive clinical evaluation for Chinese patent medicine based on health technology assessment].

At present, most of Chinese patent medicines have problems, such as weak scientific basis, unclear clinical value evaluation, etc., which lead to the lack of sufficient evidence for the entry into the essential medicine list, medical insurance catalog and other important health resource allocation tools. This has a negative impact on the development of traditional Chinese medicine. It is urgent to establish a comprehensive evaluation methodology system of Chinese patent medicine in China. There are at least three reasons including producing evidence for clinical rational use scientifically, developing an objective and transparent selecting strategy, eventuating and highlighting its clinical value. The process and method of health technology assessment(HTA) can provide reference for the establishment of comprehensive evaluation method of Chinese patent medicine. However, HTA is rarely carried out in the field of traditional Chinese medicine. The latest domestic and international research showed that HTA combined with multi-criteria decision analysis(MCDA) can increase the transparency of decision-making and improve the quality of decision-making. The combined two formed the EVIDEM framework, which is conducive to drug selection and its clinical use. In this paper, the EVIDEM framework was introduced to establish the methodology framework of the comprehensive clinical evaluation system of Chinese patent medicine. A preliminary research idea has been put forward. In the future, we can establish a set of comprehensive clinical evaluation methods for Chinese patent medicine in cooperation with relevant national drug decision-making departments and management departments. It is believed that such cooperation could promote the full implementation of the re-evaluation for Chinese patent medicine.

Characteristics and health burden of the undiagnosed population at risk of chronic obstructive pulmonary disease in China.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality in China. However, identifying patients has proved challenging, resulting in widespread under-diagnosis of the condition. We examined the prevalence of COPD diagnosis and COPD risk among adults in urban mainland China, the factors associated with having a COPD diagnosis or COPD risk, and the healthcare resource use and health outcomes of these groups compared with controls. METHODS: Respondents to the 2017 National Health and Wellness Survey in China (n = 19,994) were classified into three groups: 'COPD Diagnosed', 'COPD Risk (undiagnosed)', and Control (unaffected), based on their self-reported diagnosis and Lung Function Questionnaire (LFQ) score. The groups were characterised by sociodemographic, health-related quality of life (HRQoL), productivity impairment, and healthcare resource use. Pairwise comparisons (t tests and chi-squared tests) and multivariable regression analyses were used to investigate factors associated with being at risk of, or diagnosed with, COPD. RESULTS: 3320 (16.6%) respondents had a suspected risk of COPD but did not report receiving a diagnosis. This was projected to 105.3 million people, or 16.9% of adult urban Chinese. Of these respondents with an identified risk, only 554 (16.7%) were aware of COPD by name. Relative to those without COPD, those with a risk of COPD (undiagnosed) had significantly greater healthcare resource use, lower productivity and lower HRQoL not only compared to those without COPD, but also compared to people with a COPD diagnosis. Factors associated with increased odds of being at risk of COPD were older age, smoking, alcohol consumption, overweight BMI, occasional exercise, higher comorbidities, asthma diagnosis, being female, lower education, not being employed, and living in a high pollution province (p < 0.05). CONCLUSIONS: There is a substantial group of individuals, undiagnosed, but living with a risk of COPD, who have impaired HRQoL, lower productivity and elevated healthcare resource use patterns. Case-detection tools such as the LFQ may prove a quick and cost-effective approach for identifying these at-risk individuals for further definitive testing and appropriate treatment in China.
