Scientific research competitiveness in hospitals: A narrative review of major hospital ranking systems in China

BACKGROUND AND AIMS: Several hospital ranking systems have been created in China recently, but there is still a lack of comprehensive analysis of the weight and significance of scientific research in hospital ranking. The present study aimed to identify and analyze the role of scientific research competitiveness in various hospital ranking systems in China. METHODS: Over 200 materials published between 2010 and 2020 and related to three mainstream hospital ranking systems in China were reviewed. The methodologies applied in the three ranking systems were analyzed and compared. In addition, the comparative learning and analysis of Top 10 and Top 46–55 hospitals according to the ranking system of China's Best Hospital Rankings was performed for a longitudinal study. RESULTS: The three major hospital rankings had different scientific research capability ranking methodologies and emphases of scientific research evaluation systems. The most commonly used indicators were science citation index (SCI) publications, National Scientific Foundation of China funding, a number of national key laboratories, and a number of academicians. The relative standing of several top hospitals showed slightly different in the three major Chinese hospital ranking systems. For the longitudinal study, we found that the fluctuation of the ranking of the Top 46–55 hospitals was significantly higher than that of the Top 10 hospitals, in which scientific research played a vital role. CONCLUSION: The proportion of scientific research plays an important role in the hospital ranking systems. The quality and quantity of SCI publications, the key indicators of national projects, and top academic talents are the most important factors used to evaluate the level of hospital scientific research, and thus affect the ranking of hospitals.
