Low- and middle-income countries (LMICs) have been searching for effective strategies to reform their inefficient and wasteful public hospitals. Recently, China developed a model of systemic reforms called the Sanming model to address the inefficiency and waste at public hospitals. In this article, we explain and evaluate how the Sanming model reformed its 22 public hospitals in 2013 by simultaneously restructuring the hospital governance structure, altering the payment system to hospitals, and realigning physicians' incentives. By employing the difference-in-difference (DID) method and using the hospital-level data from 187 public hospitals in Fujian province, we find that the Sanming model has reduced medical costs significantly without measurably sacrificing clinical quality and productive efficiency. The systemic reform, on average, has reduced the medical care cost per outpatient visit and per inpatient admission by 6.1% (P-value = 0.0445) and 15.4% (P-value < 0.001), respectively. It is largely accomplished through a decrease in drug expenditures per outpatient visit and per inpatient admission of about 29% (P-value < 0.001) and 53% (P-value < 0.001). These results show that the Sanming model has achieved at least a short-term success in improving the performance of the public hospitals. These findings suggest that such a systemic transformation of public hospitals, where the governance structure, payment system and physician compensation methods are aligned, are crucial to improving their performance; it holds critical lessons for China and other LMICs.
A simple consortium consisted of two members of Klebsiella sp. A1 and Comamonas sp. A2 was isolated from the sewage of a pesticide mill in China. One member of Klebsiella sp. A1 is a novel strain that could use atrazine as the sole carbon and nitrogen source. The consortium showed high atrazine-mineralizing efficiency and about 83.3% of 5 g l(-1) atrazine could be mineralized after 24 h degradation. Contrary to many other reported microorganisms, the consortium was insensitive to some nitrogenous fertilizers commonly used, not only in presence of 200 mg l(-1) atrazine but also in 5 g l(-1) atrazine mediums. After 24 h incubation, 200 mg l(-1) atrazine was completely mineralized despite of the presence of urea, (NH(4))(2)CO(3) and (NH(4))(2)HPO(4) in the medium. Very minor influence was observed when NH(4)Cl was added as additional nitrogen source. Advantages of the simple consortium, high mineralizing efficiency and insensitivity to most of exogenous nitrogen sources, all suggested application potential of the consortium for the bioremediation of atrazine-contaminated soils and waters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
