Guidelines recommend low-molecular-weight heparin (LMWH) and direct oral anticoagulants (DOACs) rather than unfractionated heparin (UFH) for treatment of acute pulmonary embolism (PE) given their efficacy and reduced risk of bleeding. Using data from a large consortium of US hospitals, we examined trends in initial anticoagulation among hospitalized patients diagnosed with acute PE. ⋯ Despite recommendations that LMWH and DOACs be considered first-line for most patients with acute PE, use of UFH is common and increasing. Further research is needed to elucidate factors associated with persistent use of UFH and opportunities for deimplementation of low-value care.

Asystole is the most common initial rhythm in out-of-hospital cardiac arrest (OHCA) but indicates a low likelihood of neurologic recovery. This study aimed to develop a novel scoring system to be easily applied at the time of emergency department arrival for identifying favorable neurologic outcomes in OHCA survivors with an asystole rhythm. ⋯ Although external validation studies must be performed, among OHCA patients with asystole, the WBC-ASystole scoring system may identify those patients who are likely to have a favorable neurologic outcome.
