Shibahashi K, et al. - Using a nationwide population-based registry, researchers examined the outcomes of dispatcher-initiated telephone cardiopulmonary resuscitation (TCPR) in Japan. They divided adult Japanese patients with out-of-hospital cardiac arrest (OHCA; n = 582,483, age ≥ 18 years) into 3 groups: no bystander CPR (NCPR) before emergency medical service arrival (n = 448,606), bystander-initiated CPR (BCPR) performed without assistance (n = 46,964), and TCPR (n = 86,913). They observed significantly better outcomes among patients who received TCPR than those who did not receive CPR. However, Compared with the outcomes in the BCPR group, the TCPR outcomes were less favorable. These findings emphasize the necessity for better protocol development and enhanced education to advance dispatcher instructions in Japan, which may assist in reducing the gap between the BCPR and TCPR outcomes and further improving the outcomes after OHCA.
