去年報道說美國急診室誤診每年多達7百萬，看來誤診是挺多的

The report, published Thursday by the US Department of Health and Human Services’ Agency for Healthcare Research and Quality, reviewed nearly 300 studies published between January 2000 and September 2021. The researchers estimate that 7.4 million misdiagnosis errors are made every year, 2.6 million people receive a harm that could have been prevented, and another 370,000 are permanently disabled or die because of the misdiagnosis. This equates to about 1,400 diagnostic errors every year per emergency room across the country. https://www.cnn.com/2022/12/15/health/hospital-misdiagnoses-study/index.html
