What are the early risk factors for ICU readmission during the first year after lung transplantation?
Initial severity of haemodynamic failure and prolonged postoperative course are key determinants of ICU readmissions in the first year after lung transplantation.
High-dose intraoperative catecholamines and longer initial ICU stay were associated with 1-year readmission after LT; hypothesis-generating for perioperative risk stratification, prospective validation needed.
BACKGROUND: Predictive factors of intensive care readmissions after lung transplantation (LT) have not been established. The main objective of this study was to assess early risk factors for ICU readmission during the first year after LT. METHODS: This retrospective, observational, single-centre study included all consecutive patients who underwent LT in our institution between January 2016 and November 2019. Patients who died during the initial hospitalisation in the ICU were excluded. Surgical and medical ICU readmissions were collected during the first year. The results are expressed as medians, interquartile ranges, absolute numbers and percentages. Statistical analyses were performed using the chi-square test, Fisher's exact test and Mann-Whitney U test as appropriate (p < 0.05 as significance). Multivariate analysis was performed to identify independent risk factors for readmission. The Paris-North-Hospitals Institutional Review Board reviewed and approved the study. RESULTS: A total of 156 patients were analysed. Eighteen of them (12%) died during the initial ICU hospitalisation. During the first year after LT, ICU readmission was observed for 49/138 (36%) patients. Among these patients, 14/49 (29%) died during the study period. Readmission was mainly related to respiratory failure (35 (71%) patients), infectious diseases (28 (57%) patients), airway complications (11 (22%) patients), and immunologic complications (4 (8%) patients). In the multivariate analysis, ICU readmission was associated with the use of high doses of catecholamines during surgery, and the increased duration of initial ICU stay. CONCLUSION: The initial severity of haemodynamic failure and a prolonged postoperative course seem to be key determinants of ICU readmissions after LT.

Atchade et al. (2021) conducted an observational in Lung transplantation (n=156). High doses of catecholamines during surgery and increased duration of initial ICU stay was evaluated on ICU readmission during the first year after lung transplantation. ICU readmission occurred in 36% of patients in the first year after lung transplantation and was associated with high intraoperative catecholamine doses and prolonged initial ICU stay.
