Hermel H, Bosson N, Fang A, et al. - Despite being beneficial for out‐of‐hospital cardiac arrest, implementation of targeted temperature management (TTM) within the United States remains low. Researchers sought to determine the prevalence and factors linked with TTM use in a large, urban‐suburban regional system of care. In this retrospective analysis from the Los Angeles County regional cardiac system of care serving a population of > 10 million residents, they included 8,072 patients. Of these patients, 4,154 patients (51.5%) received TTM and 3,767 patients (46.7%) did not receive TTM. Findings overall suggest that this regional system of care has higher use of TTM than previously reported in the literature at just over 50%. Younger age, male gender, an initial shockable rhythm, witnessed arrest, and receiving coronary angiography were noted to be linked with receiving TTM. They suggest use of integrated systems of care to be a novel approach to raise TTM use within the United States.
