Epidemiology of Tracheostomized Adult Patients Admitted to Specialized Weaning Centers After Acute COVID-19.

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.

[Long-term follow-up of tracheostomized patients post severe acquired brain injury]. / Seguimiento a largo plazo de pacientes traqueostomizados post injuria cerebral adquirida grave.

INTRODUCTION: About 50% of patients hospitalized for severe acquired brain injury require tracheostomy, and many of them need long-term care. The main objective of this study was to describe the evolution of patients with severe acquired brain injury (sABI) tracheotomized who entered rehabilitation. Secondarily, mortality related to the success or failure of decannulation and survival at 12 months of discharge were studied. METHODS: A single-center prospective observational quantitative study. Users over 18 years of age were recruited prospectively and consecutively, tracheostomized after sABI, and admitted to a rehabilitation center between April 2018 and March 2020. RESULTS: Fifty patients were included for analysis. The stay in the center was 203 (RIQ 93-320) days. At discharge to the institution, 32 (64%) patients managed to be successfully decannulated. The median number of days from admission to the center to decannulation was 49 (12-172). No decannulation failure was observed. Mortality at 12 months follow-up was 32%, five (16%) of the 32 patients who managed to be decannulated, and 11 (61%) of 18 who failed to achieve decannulation died within 12 months of follow-up. The relationship between decannulation success and mortality at 12 months of follow-up was statistically significant (p= 0.002). DISCUSSION: Addressing the decannulation process early and properly guided is relevant as it may impact long-term survival.

Introducción: Alrededor del 50% de los pacientes hospitalizados por injuria cerebral adquirida grave requieren traqueostomía y cuidados a largo plazo. El objetivo principal de este estudio fue describir la evolución de enfermos con injuria cerebral adquirida grave (ICAg) traqueostomizados que ingresaron a rehabilitación. Secundariamente se estudió el fracaso de la decanulación y la supervivencia a los 12 meses del alta. Métodos: estudio cuantitativo observacional prospectivo de centro único. Se incorporó al estudio, de forma prospectiva y consecutiva, usuarios mayores de 18 años, traqueostomizados posterior a ICAg ingresados a un centro de rehabilitación entre abril de 2018 y marzo de 2020. Resultados: se incluyeron para el análisis 50 pacientes. La estancia en el centro fue de 203 (RIQ 93-320) días. Al alta de la institución, 32 (64%) pacientes pudieron ser decanulados exitosamente. El tiempo transcurrido desde el ingreso al centro hasta la decanulación fue de 49 (12-172) días. No se observó fracaso de la decanulación. La mortalidad a los 12 meses de seguimiento fue de 32%, cinco (16%) de los 32 pacientes que pudieron ser decanulados y 11 (61%) de los 18 que no lograron la decanulación fallecieron dentro de los 12 meses de seguimiento. La relación entre la decanulación y la mortalidad a los 12 meses de seguimiento resultó estadísticamente significativa (p = 0.002). Discusión: La supervivencia global fue relativamente elevada, el proceso de decanulación resulta relevante ya que puede tener impacto en la supervivencia a largo plazo.
