Abstract
OBJECTIVES Patients on extracorporeal life support (ECLS), like other critically ill patients, are transported to other institutions for various reasons. However, little has been reported concerning the characteristics and clinical outcomes of transported patients compared with those of in-house patients. METHODS A total of 281 adult patients received ECLS between January 2014 and August 2016. Patients who underwent cannulation at another institution by our team were excluded. Patients were divided into 2 groups: transported group (N = 46) and in-house group (N = 235). All 46 patients were safely transported without serious adverse events. The mean travel distance was 206±140 km, with a mean travel time of 78 ± 57 min. Following propensity score matching, 44 transported patients were matched to 148 in-house patients. RESULTS In the matched population, the mean age was 48 ± 13 years in the transported group and 49 ± 17 years in the in-house group (P = 0.70). The ECLS type (venoarterial/venovenous) comprised 35/9 (79.5/20.5%) in the transported group and 119/29 (80.4/19.6%) in the in-house group (P = 0.93). Seventeen (38.6%) extracorporeal cardiopulmonary resuscitations were performed in the transported group and 59 (39.9%) were performed in the in-house group (P = 0.91). The incidence of limb ischaemia and acute kidney injury was higher in the transported group (P = 0.007 and P = 0.001, respectively). However, the rate of survival to discharge did not differ between the groups (63.6% in the transported group vs 64.2% in the in-house group, P = 0.94) and there was no difference in overall mortality (P = 0.99). CONCLUSIONS Although transported patients had more complications than in-house ECLS patients, clinical outcomes were comparable in the matched population. Transporting ECLS patients to an experienced centre may be justified based on our experience.

THE KOREAN JOURNAL OF THORACIC AND CARDIOVASCULAR SURGERY 2017; 50:363-370. [PMID: 29124028 PMCID: PMC5628964 DOI: 10.5090/kjtcs.2017.50.5.363] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/12/2016] [Revised: 04/16/2017] [Accepted: 05/09/2017] [Indexed: 11/16/2022]
Abstract
Background Extracorporeal life support (ECLS) is widely used in refractory heart or lung failure, and the demand for inter-facility transportation on ECLS is expanding. However, little is known about post-transportation outcomes, the clinical safety of such transportation, or the characteristics of the transported patients. Methods This was a retrospective review of a 3-year, single-institution experience with inter-facility ECLS transport, as well as a comparative analysis of clinical outcomes with those of in-house patients. We also analyzed the risk factors for hospital mortality in the entire ECLS population using univariate and multivariate analyses to investigate the effects of transport. Results All 44 patients were safely transported without adverse events. The average travel distance was 178.7 km, with an average travel time of 74.0 minutes. Early survival of the transported group seemed to be better than that of the in-house group, but the difference was not statistically significant (70.5% vs. 56.6%, p=0.096). The incidence of complications was similar between the 2 groups, except for critical limb ischemia, which was significantly more common in the transported group than in the in-house group (25.0% vs. 8.1%, p=0.017). After adjusting for confounders, being part of the transported group was not a predictor of early death (adjusted odds ratio, 0.689; p=0.397). Conclusion Transportation of patients on ECLS is relatively safe, and the clinical outcomes of transported patients are comparable to those of in-house ECLS patients. Although matched studies are required, our study demonstrates that transporting patients on ECLS did not increase their risk of hospital mortality after adjustment for other factors.
