RESUMEN
BACKGROUND: Extracorporeal cardiopulmonary resuscitation (ECPR) is an established rescue therapy for both out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA). However, there remains significant heterogeneity in populations and outcomes across different studies. The primary aim of this study was to compare commonly used selection criteria and their effect on survival and utilisation in an Australian ECPR cohort. METHODS: We performed a retrospective, observational study of three established ECPR centres in Australia, including cases from 1 January 2013 to 31 December 2020 to establish the baseline cohort. We applied five commonly used ECPR selection criteria, ranging from restrictive to liberal. RESULTS: The baseline cohort included 199 ECPR cases: 95 OHCA and 104 IHCA patients. Survival to hospital discharge was 20% for OHCA and 41.4% for IHCA. For OHCA patients, strictly applying the most restrictive criteria would have resulted in the highest survival rate 7/16 (43.8%) compared to the most liberal criteria 16/73 (21.9%). However, only 16/95 (16.8%) in our cohort strictly met the most restrictive criteria versus 73/95 (76.8%) with the most liberal criteria. Similarly, in IHCA, the most restrictive criteria would have resulted in a higher survival rate in eligible patients 10/15 (66.7%) compared to 27/59 (45.8%) with the most liberal criteria. With all criteria a large portion of survivors in IHCA would not have been eligible for ECMO if strictly applying criteria, 33/43 (77%) with restrictive and 16/43 (37%) with the most liberal criteria. CONCLUSIONS: Adherence to different selection criteria impacts both the ECPR survival rate and the total number of survivors. Commonly used selection criteria may be unsuitable to select IHCA ECPR patients.

INTRODUCTION: Rehabilitation outcomes in cardiac arrest survivors are largely unknown, with no data comparing out-of-hospital cardiac arrests (OHCA) and in-hospital cardiac arrests (IHCA). This study aimed to describe and compare inpatient rehabilitation outcomes in these patients who were admitted from intensive care units (ICU). METHODS: A retrospective linkage and analysis of cardiac arrest patients in the Australian and New Zealand Intensive Care Society Adult Patient Database and the Australasian Rehabilitation Outcomes Centre inpatient dataset discharged to inpatient rehabilitation between January 2017 and June 2018. Primary outcome was the functional improvement during rehabilitation (difference between the Functional Independence Measurement (FIM) score on admission and discharge). Multivariate regression analyses were performed to determine factors associated with functional improvement. RESULTS: In the 240 (84 OHCA and 156 IHCA) patients included, the median length of inpatient rehabilitation was 15 days [1st-3rd quartile (Q1-Q3): 9-24]. OHCA patients were more likely to be admitted to rehabilitation for neurological issues (41.7%) and IHCA for medical reasons (51.9%). Median (Q1-Q3) change in total FIM scores was similar between the two groups (24.5[10-37]) vs 21[11-31], adjusted p = 0.20), with most of the FIM change seen in the motor items, and this was only associated with a lower admission FIM score. The majority of OHCA and IHCA patients were discharged home (91.5% and 89.7%, respectively), although with an increased need for a carer at home compared to baseline (27.2% to 55.6%). CONCLUSION: Patients discharged from ICU following OHCA and IHCA achieved reasonable and similar functional improvement during inpatient rehabilitation.

The severe acute respiratory syndrome coronavirus 2 (COVID-19) pandemic has placed an unprecedented challenge on healthcare systems across the globe. Rapid assessment of the cardiorespiratory function to monitor disease progression and guide treatment is essential. Therefore, we have designed the COVID-US: a simplified cardiopulmonary ultrasound approach to use in suspected and confirmed COVID-19 patients, to aid front-line health workers in their decision-making in a surge crisis.
RESUMEN
BACKGROUND: Multiple screening Duplex ultrasound scans (DUS) are performed in trauma patients at high risk of deep vein thrombosis (DVT) in the intensive care unit (ICU). Intensive care physician performed compression ultrasound (IP-CUS) has shown promise as a diagnostic test for DVT in a non-trauma setting. Whether IP-CUS can be used as a screening test in trauma patients is unknown. Our study aimed to assess the agreement between IP-CUS and vascular sonographer performed DUS for proximal lower extremity deep vein thrombosis (PLEDVT) screening in high-risk trauma patients in ICU. METHODS: A prospective observational study was conducted at the ICU of Alfred Hospital, a major trauma center in Melbourne, Australia, between Feb and Nov 2015. All adult major trauma patients admitted with high risk for DVT were eligible for inclusion. IP-CUS was performed immediately before or after DUS for PLEDVT screening. The paired studies were repeated twice weekly until the DVT diagnosis, death or ICU discharge. Written informed consent from the patient, or person responsible, or procedural authorisation, was obtained. The individuals performing the scans were blinded to the others' results. The agreement analysis was performed using Cohen's Kappa statistics and intraclass correlation coefficient for repeated binary measurements. RESULTS: During the study period, 117 patients had 193 pairs of scans, and 45 (39%) patients had more than one pair of scans. The median age (IQR) was 47 (28-68) years with 77% males, mean (SD) injury severity score 27.5 (9.53), and a median (IQR) ICU length of stay 7 (3.2-11.6) days. There were 16 cases (13.6%) of PLEDVT with an incidence rate of 2.6 (1.6-4.2) cases per 100 patient-days in ICU. The overall agreement was 96.7% (95% CI 94.15-99.33). The Cohen's Kappa between the IP-CUS and DUS was 0.77 (95% CI 0.59-0.95), and the intraclass correlation coefficient for repeated binary measures was 0.75 (95% CI 0.67-0.81). CONCLUSIONS: There is a substantial agreement between IP-CUS and DUS for PLEDVT screening in trauma patients in ICU with high risk for DVT. Large multicentre studies are needed to confirm this finding.
RESUMEN
INTRODUCTION: The role of immediate coronary angiography and percutaneous coronary intervention (angio±PCI), amongst comatose survivors of out-of-hospital cardiac arrest is unclear. This study was undertaken to evaluate if immediate angio±PCI compared to no initial intervention improves neurological outcome at hospital discharge amongst comatose survivors of out-of-hospital pulseless ventricular tachycardia (pVT) or ventricular fibrillation (VF). METHODS: All patients admitted to Intensive Care Unit (ICU) following an out-of-hospital VF/pVT arrest from 1/1/2003 to 31/12/2008 were included. Outcome of patients who underwent immediate angio±PCI was compared to those who did not undergo any intervention before admission to ICU. Good outcome was defined as survival to hospital discharge with Cerebral Performance Category (CPC) score of 1 or 2. RESULTS: Thirty-five patients (30 Males, 5 Females, mean age 60.3±10.1), underwent angio±PCI prior to ICU admission. A further 35 patients (20 Males, 15 Females, mean age 61.1±17.6 years) were admitted directly to ICU without undergoing any intervention. Forty percent (14/35) of patients who had immediate coronary intervention survived to hospital discharge with a good outcome compared to 31% (11/35) patients who did not undergo any intervention. After adjusting for other covariates, the probability of good outcome at hospital discharge was related to severity of illness (SAPS-II) score at ICU admission (adj OR=0.87, 95% CI 0.81-0.94, p<0.01). Immediate angio±PCI compared to no intervention was associated with an improved outcome but this difference was statistically not significant (adj OR 1.32, 95% CI 0.26-7.87, p=0.78). CONCLUSION: Immediate angio±PCI in comatose survivors of out-of-hospital VF/pVT arrest did not lead to better neurological outcome at hospital discharge.
