Frailty is associated with increased 30-day mortality and non-home discharge following perioperative cardiac arrest. We estimated the predictive accuracy of frailty when added to baseline risk prediction models. ⋯ Incorporating frailty did not significantly improve predictive accuracy of models for 30-day mortality and non-home discharge following perioperative resuscitation. Thus, demonstrated associations between frailty and outcomes of perioperative resuscitation may not translate into improved predictive accuracy. When engaging patients in shared decision-making regarding do-not-resuscitate orders perioperatively, providers should acknowledge uncertainty in anticipating resuscitation outcomes.

Interpretation of end-tidal CO2 (ETCO2) during manual cardiopulmonary resuscitation (CPR) is affected by variations in ventilation and chest compressions. This study investigates the impact of standardising ETCO2 to constant ventilation rate (VR) and compression depth (CD) on absolute values and trends. ⋯ Standardising ETCO2 eliminates effects of VR and CD variations during manual CPR and facilitates comparison of values and trends among and within patients. Its clinical application for guidance of resuscitation warrants further investigation.

To assess patient socio-demographic and disease characteristics associated with the initiation, timing, and completion of emergency care and treatment planning in a large UK-based hospital trust. ⋯ Variation in the initiation, timing, and completion of ReSPECT plans was identified by applying an evaluation framework. Digital storage of ReSPECT plan data presents opportunities for assessing trends and completion of the ReSPECT planning process and benchmarking across sites. Further research is required to monitor and understand any inequity in the implementation of the ReSPECT process in routine care.

Dispatcher-assistance in lay rescuer infant CPR: Promoting the enhancement of the guiding protocol.
In the 2021 guidelines of the European Resuscitation Council (ERC) on infant CPR, a two-thumb encircling technique (TTET) is advised instead of the former two-finger technique (TFT), even for single rescuers. It is however unclear if this is also feasible and effective in case of dispatcher-assisted CPR by untrained bystanders and was explored in a cross-over infant manikin study including CPR-trained students and lay people. ⋯ Results suggest it is feasible to advice single lay rescuers to perform TTET as part of a dispatcher-assisted CPR protocol, although we identified an ongoing risk, regardless of the technique advised, of suboptimal compression depth. Further research should be performed to confirm these preliminary data and explore optimal protocols for dispatcher-assisted infant CPR.
