The Postcardiac Arrest Consult Team: Impact on Hospital Care Processes for Out-of-Hospital Cardiac Arrest Patients.

OBJECTIVE: To evaluate whether a Post-Arrest Consult Team improved care and outcomes for patients with out-of-hospital cardiac arrest. DESIGN: Prospective cohort study of Post-Arrest Consult Team implementation at two hospitals, with concurrent controls from 27 others. SETTING: Twenty-nine hospitals within the Strategies for Post-Arrest Care Network of Southern Ontario, Canada. PATIENTS: We included comatose adult nontraumatic out-of-hospital cardiac arrest patients surviving more than or equal to 6 hours after emergency department arrival who had no contraindications to targeted temperature management. INTERVENTION: The Post-Arrest Consult Team was an advisory consult service to improve 1) targeted temperature management, 2) assessment for percutaneous coronary intervention, 3) electrophysiology assessment, and 4) appropriately delayed neuroprognostication. MEASUREMENTS AND MAIN RESULTS: We used generalized linear mixed models to explore the association between Post-Arrest Consult Team implementation and performance of targeted processes. We included 1,006 patients. The Post-Arrest Consult Team was associated with a significant reduction over time in rates of withdrawal of life-sustaining therapy within 72 hours of emergency department arrival on the basis of predictions of poor neurologic prognosis (ratio of odds ratios, 0.13; 95% CI, 0.02-0.98). Post-Arrest Consult Team was not associated with improved successful targeted temperature management (ratio of odds ratios, 0.91; 95% CI, 0.31-2.65), undergoing angiography (ratio of odds ratios, 1.91; 95% CI, 0.17-21.04), receiving electrophysiology consultation (ratio of odds ratios, 0.93; 95% CI, 0.11-8.16), or functional survival (ratio of odds ratios, 0.75; 95% CI, 0.19-2.94). CONCLUSIONS: Implementation of a Post-Arrest Consult Team reduced premature withdrawal of life-sustaining therapy but did not improve rates of successful targeted temperature management, coronary angiography, formal electrophysiology assessments, or functional survival for comatose patients after out-of-hospital cardiac arrest.

The Mindset of the Resuscitationist.

Excellent resuscitation requires technical skills and knowledge, but also the right mindset. Expert practitioners must master their internal affective state, and create the environment that leads to optimal team performance. Leaders in resuscitation should use structured approaches to prepare for resuscitation, and psychological skills to enhance their performance including mental rehearsal, positive self-talk, explicit communication strategies, and situational awareness skills. Postevent recovery is equally important. Providers should have explicit plans for recovery after traumatic cases, including developing resilience and self-compassion. Experts in resuscitation can improve their performance (and that of their team) by consciously incorporating psychological skills into their armamentarium.

Incidence, outcomes and guideline compliance of out-of-hospital maternal cardiac arrest resuscitations: A population-based cohort study.

BACKGROUND: Incidence and survival rates after cardiac arrest among pregnant women are reported for in-hospital cardiac arrests; the incidence and outcomes of maternal out-of-hospital cardiac arrest (OHCA) are unknown. Current cardiopulmonary resuscitation guidelines contain recommendations specific to this population; compliance with these has not been investigated. OBJECTIVE: To report maternal OHCA incidence, outcomes, and compliance with recommended treatment guidelines. METHODS: A population-based cohort study of consecutive maternal OHCAs from 2010 to 2014. Census data of all women of childbearing age provided the comparison. Resuscitation performance was measured against the 2010 American Heart Association (AHA) Guidelines. RESULTS: Six maternal OHCAs were identified among 1085 OHCAs occurring in females of child bearing age (15-49) years; Incidence 1.71 per 100,000 pregnant women (95% CI 0.21 to 6.18) vs. 20.18 OHCAs per 100,000 females of child bearing age (95% CI, 18 to 22.62) p < 0.0001. Survival to hospital discharge was 16.7% (95% CI 3.0, 56.4%) after maternal OHCA vs. 6.8% (95% CI 5.4, 8.4) p < 0.0001 after OHCA in all females of childbearing age, and neonatal survival was 33.3% (95% CI 9.7, 70%). CPR quality metric compliance averaged 83% (range 75% to 100%); compliance with pregnancy-specific resuscitation guidelines ranged from 0% (uterine displacement) to 100% (intravenous line insertion above diaphragm and prehospital maternal team activation). CONCLUSION: The incidence of maternal OHCA was 1.71:100,000. Survival was higher after maternal OHCA than after OHCA of non-pregnant females of childbearing age. Pregnancy-specific guideline compliance was low suggesting a need for training and better documentation to improve outcomes in these rare events.

The value of preprocedure computed tomography for planning insertion of inferior vena cava filters.

PURPOSE: To determine if valuable information could be obtained from abdominal computed tomography (CT) performed before insertion of an inferior vena cava (IVC) filter. MATERIALS AND METHODS: A retrospective review was performed on IVC filter insertions with a CT performed before the procedure. Cavagram and CT were compared for renal vein and IVC anatomy, the diameter of the IVC, and the prevalence of iliocaval thrombus. Correlations were assessed among 3 reference standards for measuring the IVC at cavography. RESULTS: The mean IVC diameter was 23.0 mm on CT. On cavagram the mean IVC diameter was assessed by using 3 reference standards: 20.7 mm, with the catheter tip as a reference; 26.9 mm, with a radiopaque ruler; and 23.4 mm, by using a lumbar vertebral body. There was good correlation among the 3 measures of IVC diameter (Pearson's r = 0.75, P < .0001) but moderate correlation with CT (r = 0.36-0.56, P < .001). The sensitivity of cavagram for detecting retroaortic and circumaortic renal veins was 40% and 0%, respectively. Nineteen accessory renal veins (12.8%) were not seen by cavagram. Thirteen patients (8.8%) had iliocaval thrombus on cavagram, of which 12 (92.3%) were not previously detected by CT. CONCLUSIONS: CT is more sensitive than cavagram for detection of renal vein variants and the level of the lowest renal vein. Therefore, if available, the CT should be reviewed before placement of an IVC filter to optimize positioning. Cavagram remains the criterion standard for detection of iliocaval thrombosis and is necessary before IVC filter insertion.
