Decannulation/Weaning Potential and Success in Home Intensive Care

Abstract

<b><i>Background:</i></b> The number of patients receiving home long-term ventilation has risen considerably in recent decades owing to medical advancements. Experts believe that the potential for ventilator weaning or tracheostoma removal is currently insufficiently exploited. <b><i>Objective:</i></b> The objective of this study was to investigate the characteristics, prognosis, and decannulation/weaning potential of patients under home intensive care. <b><i>Methods:</i></b> In this retrospective analysis of 607 patients on home intensive care, decannulation/weaning status and survival were documented for a 2-year period after initial assessment. At the time of hospital discharge, when clinicians had deemed the weaning process concluded, an independent expert noninvasively assessed the long-term decannulation/weaning. Comparative analyses based on specific criteria, such as ventilation and decannulation/weaning status, age, and underlying diseases, were performed. Potential predictors of survival were identified via multivariable logistic regression. <b><i>Results:</i></b> Eighteen percent of patients were decannulated/weaned within 2 years after hospital discharge and had better mean survival than patients not decannulated/weaned (552 vs. 420 days, <i>p</i> &#x3c; 0.001). More than half of these patients were identified to have decannulation/weaning potential based on the assessment of the independent expert. Patients with neuromuscular and neurological diseases had the best survival (546 and 501 days), patients with postsurgical conditions and cardiological diseases the worst (346 and 323 days). Underlying disease and decannulation/weaning status were significant predictors of 2-year survival. <b><i>Conclusion:</i></b> Successful decannulation/weaning of patients on long-term home intensive care is associated with better survival. Even in the absence of decannulation/weaning potential at the time of hospital discharge, patients may develop decannulation/weaning potential over time, which should therefore be assessed repeatedly.
