BackgroundPatients attempt to make appropriate decisions based on their own knowledge when choosing a doctor. In this process, the first question usually faced is that of how to obtain useful and relevant information. This study investigated the types of information sources that are used widely by patients in choosing a doctor and identified ways in which the preferred sources differ in various situations. ObjectiveThis study aims to address the following questions: (1) What is the proportion in which each of the various information sources is used? (2) How does the information source preferred by patients in choosing a doctor change when there is a difference in the difficulty of medical decision making, in the level of the hospital, or in a rural versus urban situation? (3) How do information sources used by patients differ when they choose doctors with different specialties? MethodsThis study overcomes a major limitation in the use of the survey technique by employing data from the Good Doctor website, which is now China's leading online health care community, data which are objective and can be obtained relatively easily and frequently. Multinomial logistic regression models were applied to examine whether the proportion of use of these information sources changes in different situations. We then used visual analysis to explore the question of which type of information source patients prefer to use when they seek medical assistance from doctors with different specialties. ResultsThe 3 main information sources were online reviews (OR), family and friend recommendations (FR), and doctor recommendations (DR), with proportions of use of 32.93% (559,345/1,698,666), 23.68% (402,322/1,698,666), and 17.48% (296,912/1,698,666), respectively. Difficulty in medical decision making, the hospital level, and rural-urban differences were significantly associated with patients’ preferred information sources for choosing doctors. Further, the sources of information that patients prefer to use were found to vary when they looked for doctors with different medical specialties. ConclusionsPatients are less likely to use online reviews when medical decisions are more difficult or when the provider is not a tertiary hospital, the former situation leading to a greater use of online reviews and the latter to a greater use of family and friend recommendations. In addition, patients in large cities are more likely to use information from online reviews than family and friend recommendations. Among different medical specialties, for those in which personal privacy is a concern, online reviews are the most common source. For those related to children, patients are more likely to refer to family and friend recommendations, and for those related to surgery, they value doctor recommendations more highly. Our results can not only contribute to aiding government efforts to further promote the dissemination of health care information but may also help health care industry managers develop better marketing strategies.

This study investigates the impact of media sentiment on firms' investment efficiency in the Chinese market during 2007–2017. We find that increased media sentiment can lead to overinvestment and thus distort investment efficiency, but it has no significant effect on underinvestment. Further, mediation analysis shows that financing constraints mediates the media sentiment effects on overinvestment. To mitigate potential endogenous problems, we employ instrumental variable approach and propensity score matching method. The main findings hold after a battery of robustness tests. Further tests show that corporate governance factors can ameliorate the adverse effect of news sentiment on corporate investment efficiency. [ABSTRACT FROM AUTHOR]

In this study, we examine the effects of lead independent directors (LIDs) on firms' earnings management. On the basis of US firms from 2000 to 2018, those with LIDs managed earnings less, as reflected by the absolute value of discretionary accruals. Specifically, we find the effect is likely to be more prominent among firms with less disclosure transparency, weaker corporate governance and higher risk. In addition, we find that firms with LIDs tend to increase R&D and capital expenditures, reduce leverages and enhance firm values. Overall, the findings indicate the monitoring of LIDs can effectively reduce firms' earnings management and enhance firm values. [ABSTRACT FROM AUTHOR]
