To evaluate the cost-effectiveness of practices with and without termination-of-resuscitation (TOR) rules for out-of-hospital cardiac arrest (OHCA), using an analytic model based on a nationwide population-based registry in Japan. ⋯ No-rule scenario was not cost-effective compared with BLS-rule scenario within acceptable willingness-to-pay thresholds. Further research on health economics of TOR rules is warranted to support constructive discussion on implementing TOR rules.

Poisoning is an important cause of out-of-hospital cardiac arrest which can be challenging to manage. Neurological outcomes after poisoning-induced out-of-hospital cardiac arrest (POHCA) are yet to be fully elucidated. This retrospective cohort study sought to describe the characteristics of POHCA, and identify factors associated with favourable neurologic outcomes. ⋯ POHCA is associated with favourable neurological outcomes and requires aggressive resuscitation. However, in patients who required prolonged resuscitation, the outcomes of POHCA were not different from those of non-POHCA. The decision to perform prolonged resuscitation should be guided on a case-by-case basis based on a range of factors.

Cardiac arrest survivors are at risk of long-term cognitive impairment. Patients with cognitive impairments do not always have cognitive complaints and vice versa. Not reporting cognitive complaints could be caused by a lack of awareness. We hypothesized that caregivers report more cognitive failures than patients, indicating patients' lack of insight into cognitive functioning. ⋯ This study does not support a lack of awareness of cognitive impairments by long-term cardiac arrest survivors. Future research may focus on alternative explanations for why patients have less cognitive complaints than expected based on the frequency of cognitive impairments. Possible explanations include a response shift.
