Introduction: Debriefing sessions after in-hospital cardiac arrest have been demonstrated to improve teamwork and survival outcomes. Though recommended in 2020 AHA Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care, implementation remains low. Hypothesis: We postulated that a didactic training session provided to code leaders would increase rates of participation of AHA-recommended post-arrest debriefing sessions. Methods: Surveys were distributed to hospital personnel who participate in code blue/ERTs at an academic, tertiary-care medical center. Questions were graded on Likert scale to assess provider-reported perceptions of teamwork, communication, and confidence in conducting and participating in Code Blues. Participants were stratified in groups depending on whether they had previously participated in debriefing sessions. Primary outcomes were quantified using a Likert-type scale ranging from 1 to 5. Surveys were compared to surveys from prior years to assess if the intervention of a code blue didactics lecture delivered to code leaders resulted in any change in overall participation rate in the debriefing protocol. Results: Among 181 participants (61% female), 32% were residents, 54% nurses, 1.7% respiratory therapists. Self-evaluated current knowledge of ACLS protocols was significantly higher in the debriefing group (p = 0.0098), while there were no differences in perceived communication (p=0.76), and confidence in leading (p = 0.2) and participating (p = 0.2). We did not find a statistically significant difference in debriefing participation rate after our intervention (57% pre vs 58% post intervention, p=0.8), even when stratified by hospital role: critical care nurses (50% vs 71%, p=0.3), non-ICU nurses (68% vs 57%, p=0.3) and residents (67% vs 50%, p=0.2). Conclusions: Our study demonstrated that participation in post-code debriefing sessions was associated with a statistically significant increase in knowledge of cardiac arrest protocols. A code blue didactics lecture did not result in a statistically significant increase in post-arrest debriefing participation. Further study to elucidate methods to enhance adoption of this crucial, guideline recommended practice is warranted.

BACKGROUND: Imaging guidance for left atrial appendage (LAA) closure (LAAC), conventionally consists of transesophageal echocardiography (TEE) and fluoroscopy under general anesthesia (GA). Intracardiac echocardiography (ICE) can eliminate the need for GA, and expedite procedural logistics, and reduce the patient experience to a simple venous puncture. OBJECTIVE: To define optimal ICE views and compare procedural parameters and cost of ICE vs TEE during LAAC with the Watchman device. METHODS: Optimal ICE views of the LAA for Watchman implant were delineated using Carto-Sound and 3D rendition of the LAA in 6 patients. Procedural and financial parameters of 104 consecutive patients with standard indications for LAAC undergoing Watchman implant using ICE guidance through a single trans-septal puncture (n=53, 51%) were compared with those of TEE-guided implants (n=51, 49%) in 3 centers. RESULTS: Clinical characteristics were similar between the two groups. Total in-room, turnaround and fluoroscopy times were all shorter using ICE (p
