Jara-Palomares et al reported a score for predicting major bleeding after thrombolysis for acute pulmonary embolism. This can help to identify a patient who may require more aggressive management. The authors are from multiple institutions from around the world and members of the RIETE (RegistroInformatizado de la EnfermedadTromboembolica) investigation.
BACS is an acronym for bleeding, age, cancer and syncope.
