A New, Evidence-based Estimate of Patient Harms Associated with Hospital Care
如果您真心願意找的話，很容易找到。
不是非常確定您是否真的感興趣，但為方便閱讀，搬過來原文的數據推算過程，（注：是推算，不是原始數據。）
The ratio projects to a death rate from adverse events of 0.89%. This is well below the percentages from Medicare and tertiary-care studies (1.1%–1.4%) and well above the data from the North Carolina study (0.60%). There were an estimated 34.4 million hospital discharges in 2007,26 and the average percentage of preventable adverse events among all adverse events in the 3 studies where this was reported or postulated was 69% (averaged from Table 2). Thus, the best estimate from combining these 4 studies is 34,400,000 × 0.69 × 0.0089 = 210,000 preventable adverse events per year that contribute to the death of hospitalized patients—based primarily on evidence in hospital medical records found by the GTT method.
