Abstract
BACKGROUND Epidemiological data on patients with COVID-19 referred to specialized weaning centers (SWCs) are sparse, particularly in low- and middle-income countries. Our aim was to describe clinical features, epidemiology, and outcomes of subjects admitted to SWCs in Argentina. METHODS We conducted a prospective, multi-center, observational study between July 2020-December 2021 in 12 SWCs. We collected demographic characteristics, laboratory results, pulmonary function, and dependence on mechanical ventilation at admission, decannulation, weaning from mechanical ventilation, and status at discharge. A multiple logistic model was built to predict home discharge. RESULTS We enrolled 568 tracheostomized adult subjects after the acute COVID-19 phase who were transferred to SWCs. Age was 62 [52-71], males 70%, Charlson comorbidity index was 2 [0-3], and length of stay in ICU was 42 [32-56] d. Of the 315 ventilator-dependent subjects, 72.4% were weaned, 427 (75.2%) were decannulated, and 366 subjects (64.5%) were discharged home. The mortality rate was 6.0%. In multivariate analysis, age (odds ratio 0.30 [95% CI 0.16-0.56], P < .001), Charlson comorbidity index (odds ratio 0.43 [95% CI 0.22-0.84], P < .01), mechanical ventilation duration in ICU (odds ratio 0.80 [95% CI 0.72-0.89], P < .001), renal failure (odds ratio 0.40 [95% CI 0.22-0.73], P = .003), and expiratory muscle weakness (odds ratio 0.35 [95% CI 0.19-0.62], P < .001) were independently associated with home discharge. CONCLUSIONS Most subjects with COVID-19 transferred to SWCs were weaned, achieved decannulation, and were discharged to home. Age, high-comorbidity burden, prolonged mechanical ventilation in ICU, renal failure at admission, and expiratory muscle weakness were inversely associated with home discharge.

Automatic tube compensation for liberation from prolonged mechanical ventilation in tracheostomized patients: A retrospective analysis. J Formos Med Assoc 2023; 122:1132-1140. [PMID: 37169656 DOI: 10.1016/j.jfma.2023.04.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Revised: 04/01/2023] [Accepted: 04/23/2023] [Indexed: 05/13/2023] Open
Abstract
BACKGROUND To analyze the predictability of an automatic tube compensation (ATC) screening test compared with the conventional direct liberation test performed before continuous oxygen support for MV liberation. METHODS This retrospective study analyzed tracheostomized patients with prolonged MV in a weaning unit of a medical center in Taiwan. In March 2020, a four-day ATC test to screen patient eligibility for ventilator liberation was implemented, intended to replace the direct liberation test. We compared the predictive accuracy of these two screening methods on the relevant outcomes in the two years before and one year after the implementation of this policy. RESULTS Of the 403 cases, 246 (61%) and 157 (39%) received direct liberation and ATC screening tests, respectively. These two groups had similar outcomes: successful weaning upon leaving the Respiratory Care Center (RCC), success on day 100 of MV, success at hospital discharge, and in-hospital survival. Receiver operating characteristic curve analysis showed that the ATC screening test had better predictive ability than the direct liberation test for RCC weaning, discharge weaning, 100-day weaning, and in-hospital survival. CONCLUSION This closed-circuit ATC screening test before ventilator liberation is a feasible and valuable method for screening PMV patients undergoing ventilator liberation in the pandemic era. Its predictability for a comparison with the open-circuit oxygen test requires further investigation.
