TCM is still facing many challenges in playing critical roles in improving public health in China. These challenges can be explained from different perspectives. In addition to the unique characteristics of TCM, economic, cultural, and historical evolution in China may also be major determinants.
The differential regulation of pulmonary surfactant proteins (SPs) is demonstrated in a murine model of Aspergillus fumigatus (Af )-induced allergic airway inflammation and hyperresponsiveness. BALB/c mice were sensitized intraperitoneally and challenged intranasally with Af extract. Enzyme-linked immunosorbent assay analysis of serum immunoglobulin (Ig) levels in these mice showed markedly increased total IgE and Af-specific IgE and IgG1. This was associated with peribronchial/perivascular tissue inflammation, airway eosinophilia, and secretion of interleukin (IL)-4 and IL-5 into the bronchoalveolar lavage fluid (BALF). Functional analysis revealed that in comparison with nonsensitized mice, allergic sensitization and challenge resulted in significant increases in acetylcholine responsiveness. To analyze levels of SPs, the cell-free supernate of the BALF was further fractionated by high-speed (20,000 x g) centrifugation. After sensitization and challenges, the pellet (large-aggregate fraction) showed a selective downregulation of hydrophobic SPs SP-B and SP-C by 50%. This reduction was reflected by commensurate decreases in SP-B and SP-C messenger RNA (mRNA) expression of the lung tissue of these animals. In contrast, there was a 9-fold increase in SP-D protein levels in the 20,000 x g supernate without changes in SP-D mRNA. The increased levels of SP-D showed a significant positive correlation with serum IgE (r = 0.85, P < 0.001). Tissue mRNA and protein levels of SP-A in either the large- or the small-aggregate fractions were unaffected. Our data indicate that allergic airway inflammation induces selective inhibition of hydrophobic SP synthesis accompanied by marked increases in the lung collectin SP-D protein content of BALF. These changes may contribute significantly to the pathophysiology of Af-induced allergic airway hyperresponsiveness.
Most studies on the indirect costs of an illness and the cost effectiveness of a medical intervention or employer-sponsored wellness program assume that the value of reducing the number of days employees miss from work due to illness is the wage rate. This paper presents a general model to examine the magnitude and incidence of costs associated with absenteeism under alternative assumptions regarding the size of the firm, the production function, the nature of the firm's product, and the competitiveness of the labor market. We conclude that the cost of lost work time can be substantially higher than the wage when perfect substitutes are not available to replace absent workers and there is team production or a penalty associated with not meeting an output target. In the long run, workers are likely to bear much of the incidence of the costs associated with absenteeism, and therefore be the likely beneficiaries of any reduction in absenteeism.

In this article, we examine the indirect costs (i.e., work loss and productivity costs) of employee illness from the employer's perspective. We provide a conceptual framework to help employers consider alternative views with regard to assessing indirect costs and valuing the health care they purchase. First, we discuss the matter of perspective and how an employer should view and assess indirect costs. We briefly review current models of measuring indirect costs, and we critique these models. Then we introduce a simple, conceptual framework based on the ideas of health capital and labor productivity, and we lay out the effects of health investment on indirect costs while considering what employees desire and employers can provide. Finally, we offer an agenda for further research.
BackgroundThis study adapts the ICECAP measure for Adults (ICECAP-A) to assess its capacity to measure the quality of life in China for economic evaluation.MethodsQualitative and quantitative methods were used to translate the ICECAP-A measure for wellbeing, established by the University of Birmingham, UK, to the Chinese cultural context. A focus group discussion solved the appropriateness and wording of the ICECAP attributes in Chinese; and a randomly selected sample of 1000 adults aged over 18 years were online surveyed. We conducted psychometric tests and compared the factors influencing the ICECAP-A measure with those influencing EQ-5D-3 L.ResultsMembers of the focus group discussion agreed that the five attributes of the ICECAP-A measure are sufficient to evaluate wellbeing in China. However, the terms “being settled” and “friendship” were changed to “stability” and “kindness” for the Chinese cultural context. Our results show that the Chinese version of ICECAP-A has good internal consistency with an overall Cronbach’s Alpha coefficient of 0.7999. The concurrent validity indicates that ICECAP-A is moderately correlated with EQ-5D-3 L (r ≤ 0.52).ConclusionsThe ICECAP-A measure can be adapted to evaluate wellbeing in China, but cultural changes to the wording are necessary. It is a valid measurement of wellbeing and can complement the EQ-5D already used in China. However, further work is still needed to evaluate the sensitivity of the ICECAP-A measure in relation to public health and social care.
BackgroundPublic health care dominated the services provision in China before 1980s. However, the number of private health care providers in China has been increasing since then. The growth of private hospitals escalated after a market-oriented reform was implemented in 2001. Through an experimental approach, this study aims to a better understanding of the dynamic change in preference of health care utilisation among the residents in urban China.MethodsBased on a discrete choice experiment (DCE) from a random sample of respondents in urban China, the study evaluated preference over health care attributes affecting individuals’ choice for the utilisation of hospital health care. The marginal willingness-to-pay for five health care attributes was estimated, including public/private provision of health care, by analysing mixed logit and latent class models.ResultsThe results indicated a significantly negative marginal willingness-to-pay for private health care, which was interpreted as representing people’s previous interactions with the health care system. The latent class model further suggested preference heterogeneity across our sample. We found that Hukou type, a typical indicator of socioeconomic background, was significantly related to respondents’ preference for health care utilisation. Permanent urban residents (urban Hukou) valued private health care less; in contrast rural migrants (rural Hukou) were more likely to be indifferent between public/private provision.ConclusionUrban residents in China showed a high disposition to obtain health care from the public providers of health care. Our results have implications in the context of the Chinese government attempts to expand the private health care sector in the short term. Policy makers need to consider residents’ preference for health care in health policy development as the preference can only change in the long term.Electronic supplementary materialThe online version of this article (doi:10.1186/s12913-016-1829-0) contains supplementary material, which is available to authorized users.
ObjectivesTo compare health-related quality of life (HRQoL) between patients with stable angina and the general population in China and to examine factors associated with HRQoL among patients with stable angina.MethodsA cross-sectional HRQoL survey of stable angina patients recruited from 4 hospitals (n = 411) and the general population recruited from 3 Physical Examination Centers (n = 549) was conducted from July to December, 2011 in two large cities, Tianjin and Chengdu. HRQoL was assessed using the EQ-5D, EQ-VAS, and SF-6D instruments. The health status specific to patients with stable angina was assessed using the Seattle Angina Questionnaire (SAQ). Information on socio-demographic, clinical, and lifestyle factors were also collected. Nested regressions were performed to explore how these factors were associated with HRQoL in patients with stable angina.ResultsCompared with the general population (44.2±10 years, 49.9% females), stable angina patients (68.1±12 years, 50.4% females) had significantly lower HRQoL scores in EQ-5D utility index (0.75±0.19 vs. 0.90±0.20, p<0.05), SF-6D utility index (0.68±0.12 vs. 0.85±0.11, p<0.05), and EQ-VAS (71.2±12.3 vs. 83.9±10.9, p<0.05). The differences remained (−0.05 for EQ-5D, −9.27 for EQ-VAS and −0.13 for SF-6D) after controlling for socio-economic characteristics. SAQ scores showed that stable angina patients experienced impaired disease-specific health status, especially in angina stability (40.5±34.6). Nested regressions indicated stable angina-specific health status explained most of the variation in HRQoL, among which disease perception, physical limitation, and angina stability were the strongest predictors. More physical exercise and better sleep were positively related with HRQoL.ConclusionsCompared to the general population, stable angina patients were associated with lower HRQoL and lower health utility scores, which were largely impacted by clinical symptoms. Further studies are needed to characterize the influence of geographic and cultural factors on the variations of health-related utility in stable angina patients.
