Pulmonary embolism (PE) is a potentially life-threatening condition that typically occurs when a thrombus from deep veins in the leg, pelvis, arms, or heart embolizes to the lungs.1- 2 Recent data linked PE to approximately 247 000 hospitalizations in the United States in 2006.3 To our knowledge, the case-fatality rate and estimated number of in-hospital deaths among a national representative example of hospitalizations that encompass first-listed and any-listed PE diagnoses in the United States are limited. Therefore, we report nationally representative estimates of in-hospital deaths (ie, annual number and case-fatality rate) among hospitalizations with a PE diagnosis (ie, first-listed and any-listed) in the United States by analyzing data from the 2001-2008 National Hospital Discharge Survey (NHDS).4
