Impact of extracorporeal cardiopulmonary resuscitation on outcomes of elderly patients who had out-of-hospital cardiac arrests: a single-centre retrospective analysis.

ABSTRACT:

Objectives

Little is known about the effectiveness of extracorporeal cardiopulmonary resuscitation (ECPR) for elderly patients who had out-of-hospital cardiac arrest (OHCA). The aim of this study was to examine the impact of age on outcomes among patients who had OHCA treated with ECPR.

Design

Single-centre retrospective cohort study.

Setting

A critical care centre that covers a population of approximately 1?million residents.

Participants

Patients who had consecutive OHCA aged ?18 years who underwent ECPR from 2005 to 2013.

Primary and secondary outcome measures

Primary outcomes were 1?month neurologically favourable outcomes and survival. To determine the association between advanced age and each outcome, we fitted multivariable logistic regression models using: (1) age as a continuous variable and (2) age as a categorical variable (<50 years, 50-59 years, 60-69 years and ?70 years).

Results

Overall, 144 patients who had OHCA who underwent ECPR were eligible for our analyses. The proportion of neurologically favourable outcomes was 7%, while survival was 19% in patients who had OHCA. After the adjustment for potential confounders, while advanced age was non-significantly associated with neurologically favourable outcomes (adjusted OR 0.96 (95% CI 0.91 to 1.01), p=0.08), the association between advanced age and the poor survival rate was significant (adjusted OR 0.96 (95% CI 0.93 to 0.99), p=0.04). Additionally, compared with age <50 years, age ?70 years was non-significantly associated with poor neurological outcomes (adjusted OR 0.08 (95% CI 0.01 to 1.00), p=0.051), whereas age ?70 years was significantly associated with worse survival in the adjusted model (adjusted OR 0.14 (95% CI 0.03 to 0.80), p=0.03).

Conclusions

In our analysis of consecutive OHCA data from a critical care hospital in an urban area of Japan, we found that advanced age was associated with the lower rate of 1-month survival in patients who had OHCA who underwent ECPR. Although larger studies are required to confirm these results, our findings suggest that ECPR may not be beneficial for patients who had OHCA aged ?70 years.

Project description:BACKGROUND:The prognosis in refractory out-of-hospital cardiac arrest (OHCA) with ongoing cardiopulmonary resuscitation (CPR) at hospital arrival is often considered dismal. The use of extracorporeal cardiopulmonary resuscitation (eCPR) for perfusion enhancement during resuscitation has shown variable results. We aimed to investigate outcome in refractory OHCA patients managed conservatively without use of eCPR. METHODS:We included consecutive OHCA patients with refractory arrest or prehospital return of spontaneous circulation (ROSC) in the Copenhagen area in 2002-2011. RESULTS:A total of 3992 OHCA patients with resuscitation attempts were included; in 2599, treatment was terminated prehospital, and 1393 (35%) were brought to the hospital either with ROSC (n?=?1285, 92%) or with refractory OHCA (n?=?108, 8%). Of patients brought in with refractory OHCA, 56 (52%) achieved ROSC in the emergency department. There were no differences between patients with refractory OHCA or prehospital ROSC with regard to age, sex, comorbidities, or etiology of OHCA. Time to emergency medical services (EMS) arrival was similar, whereas time to ROSC (when ROSC was achieved) was longer in refractory OHCA patients (EMS, 6 (5-9] vs. 7 [5-10] min, p?=?0.8; ROSC, 15 [9-22] vs. 27 [20-41] min, p?<?0.001). Independent factors associated with transport with refractory OHCA instead of prehospital termination of therapy were OHCA in public (OR, 3.6 [95% CI, 2.2-5.8]; p?<?0.001), witnessed OHCA (OR, 3.7 [2.0-7.1]; p?<?0.001), shockable rhythm (OR, 3.0 [1.9-4.7]; p?<?0.001), younger age (OR, 1.2 [1.1-1.2]; p?<?0.001), and later calendar year (OR, 1.4 [1.2-1.6]; p?<?0.001). Thirty-day survival was 20% in patients with refractory OHCA compared with 42% in patients with prehospital ROSC (p?<?0.001). Four of 28 refractory OHCA patients with duration of resuscitation >?60 min achieved ROSC. No difference in favorable neurological outcome in patients surviving to discharge was found (prehospital ROSC 84% vs. refractory OHCA 86%; p?=?0.7). CONCLUSIONS:Survival after refractory OHCA with ongoing CPR at hospital arrival was significantly lower than among patients with prehospital ROSC. Despite a lower survival, the majority of survivors with both refractory OHCA and prehospital ROSC were discharged with a similar degree of favorable neurological outcome, indicating that continued efforts in spite of refractory OHCA are not in vain and may still lead to favorable outcome even without eCPR.

Project description:IntroductionExtracorporeal cardiopulmonary resuscitation (ECPR) is an emerging invasive rescue therapy for treatment of refractory out-of-hospital cardiac arrests (OHCA). We aim to describe the incidence of traumatic and hemorrhagic complications among patients undergoing ECPR for OHCA and examine the association between CPR duration and ECPR-related injuries or bleeding.MethodsWe examined prospectively collected data from the Extracorporeal Resuscitation Outcomes Database (EROD), which includes ECPR-treated OHCAs from participating hospitals (October 2014 to August 2019). The primary outcome was traumatic or hemorrhagic complications, defined any of the following: pneumothorax, pulmonary hemorrhage, major bleeding, cannula site bleeding, gastrointestinal bleeding, thoracotomy, cardiac tamponade, aortic dissection, or vascular injury during hospitalization. The primary exposure was the cardiac arrest to ECPR initiation interval (CA-ECPR interval), measured as the time from arrest to initiation of ECPR. Descriptive statistics were used to compare demographic, cardiac arrest, and ECPR characteristics among patients with and without CPR-related traumatic or bleeding complications. Multivariable logistic regression was used to examine the association between CA-ECPR interval and traumatic or bleeding complications.ResultsA total of 68 patients from 4 hospitals receiving ECPR for OHCA were entered into EROD and met inclusion criteria. Median age was 51 (interquartile range 38-58), 81% were male, 40% had body mass index > 30, and 70% had pre-existing medical comorbidities. A total of 65% had an initial shockable cardiac rhythm, mechanical CPR was utilized in at least 29% of patients, and 27% were discharged alive. The median time from arrest to ECPR initiation was 73 min (IQR 60-104). A total of 37% experienced a traumatic or bleeding complication, with major bleeding (32%), vascular injury (18%), and cannula site bleeding (15%) being the most common. Compared to patients with shorter CPR times, patients with a longer CA-ECPR interval had 18% (95% confidence interval - 2-42%) higher odds of suffering a mechanical or bleeding complication, but this did not reach statistical significance (p = 0.08).ConclusionsTraumatic injuries and bleeding complications are common among patients undergoing ECPR. Further study is needed to investigate the relation between arrest duration and complications. Clinicians performing ECPR should anticipate and assess for injuries and bleeding in this high-risk population.
