Identification, diagnosis, treatment, and in-hospital outcomes of acute pulmonary embolism: Results from a single integrated health system.
BACKGROUND: Although the high-risk acute pulmonary embolism (PE) population has been described, little is known about the contemporary inpatient experience and practice patterns of the PE population as a whole. METHODS: All patients with a diagnosis of acute PE from January 1, 2016, to June 30, 2017 within our academic, multihospital health system were retrospectively identified using International Classification of Diseases, 10th Revision, codes, and data were manually abstracted by 2 clinical investigators. Descriptive analyses were performed according to clinical risk stratification categories from the European Society of Cardiology. RESULTS: Of 829 total patients, 372 (44.8%) patients had intermediate or high-risk PE. Mean age was 62.1 years old, and 42.1% of patients had a history of malignancy. One hundred fifty-three (18.5%) patients had an acute PE during a hospitalization for another indication. A total of 6.0% underwent invasive PE therapies, 26.1% required intensive care unit admission, and 9.0% experienced in-hospital death or hospice discharge. In a subgroup description, patients who developed acute PE during a hospitalization for another indication had a higher incidence of incomplete risk stratification and a higher mortality (9.8%) than the primary cohort. Mortality was attributed to PE in 48.4% of cases. CONCLUSIONS: This contemporary description of acute PE managed at a single large, multihospital academic health system highlights substantial health care utilization and high mortality despite the available of advanced therapeutics. Additional work is needed to standardize care for the heterogeneous PE population to ensure appropriate allocation of resources and improved outcomes for all PE patients.
