With the development of new media technology, patients are increasingly looking for doctor information on the Internet. To this end, researchers have researched 28 typical doctor evaluation business websites in the United States. According to the research report, recent people said in a survey interview that When choosing a doctor, online evaluation is very important for their choice. However, research on these 28 websites shows that few websites allow users to search based on conditions such as "clinical status, doctor's gender, spoken language, accepted insurance", etc. The researchers concluded that it was difficult for these commercial physician evaluation sites to find a relatively accurate quantitative evaluation of doctors. If the following are true, the arguments that support the above argument are:. ['The patient can clearly understand the treatment experience of a doctor through the doctor evaluation website.', 'U. S. doctor evaluation websites have problems such as tedious search mechanism and scarce evaluation.', 'Collecting data systematically through surveys is more likely to accumulate sufficient evaluations.', 'The survey found that one-third of the sample doctors were not rated on all websites.']
