Key takeaways:
- A better proportion of extended mechanical air flow sufferers discharged alive achieved profitable vs. unsuccessful weaning.
- The efficiently weaned group had considerably extra days spent at residence.
Sufferers receiving extended mechanical air flow discharged from the ICU had higher outcomes associated to 6-month mortality and care at residence if that they had been efficiently weaned from air flow, in keeping with information printed in CHEST.

“The choice to proceed with extended mechanical air flow is made throughout ICU care,” Nicolas Paul, MD, of the division of anesthesiology and intensive care drugs at Charité – Universitätsmedizin Berlin, instructed Healio.
Knowledge have been derived from Paul N, et al. CHEST. 2025;doi:10.1016/j.chest.2025.01.018.
However understanding long-term care trajectories, weaning probabilities, survival likelihood and high quality of life is important for well-informed selections, he continued.
“We hope that our research equips well being care employees, sufferers and caregivers with higher information of the long-term views of extended mechanical air flow,” Paul stated. “Subsequently, our findings could contribute to higher remedy selections that align with affected person preferences.”
In a secondary evaluation of the Enhanced Restoration After Intensive Care (ERIC) trial, Paul and colleagues assessed 90 sufferers handled in three ICUs and receiving invasive extended mechanical air flow (PMV) to uncover how mortality, care place transitions, readmissions and health-related high quality of life differ in sufferers who achieved profitable weaning inside 6 months of ICU discharge vs. sufferers who didn’t obtain weaning.
“Mechanical air flow is frequent amongst ICU sufferers,” Paul instructed Healio. “For many sufferers, mechanical air flow may be discontinued, however some require air flow for prolonged intervals. Whereas some sufferers may be weaned earlier than ICU discharge, others depart the ICU with mechanical air flow. Surprisingly, we all know little or no about their care trajectories after ICU discharge, notably in Europe.”
The research outlined invasive PMV as receipt of invasive mechanical air flow for a minimum of 21 days by way of endotracheal tube/tracheostomy or a minimum of 4 days by way of tracheostomy.
On this inhabitants, 21 sufferers died within the ICU and 69 sufferers have been discharged alive. Notably, 20 of the sufferers discharged alive died inside 6 months, in keeping with the research.
Researchers discovered {that a} greater proportion of sufferers discharged alive achieved profitable vs. unsuccessful weaning (75%; n = 52 vs. 25%; n = 17). Between the 2 teams, the unsuccessfully weaned group had a considerably larger proportion of sufferers who died inside 6 months (65% vs. 17%; P < .001).
When it comes to care place transitions, the median variety of transitions inside 6 months contemplating each units of sufferers was three. When divided by weaning success, the research reported that sufferers who have been efficiently vs. unsuccessfully weaned had a considerably greater median variety of transitions (4 vs. 2; P = .004).
“Initially, we discovered it stunning that sufferers who have been efficiently weaned underwent extra care place transitions than unsuccessfully weaned sufferers,” Paul instructed Healio. “We then understood that the variety of care place transitions could also be an indicator of sufferers advancing of their restoration course of.”
After 6 months, the most typical care place within the efficiently weaned group was residence (50%), adopted by nursing properties (19%). In distinction, solely 12% of sufferers within the unsuccessfully weaned group have been residence or in a nursing residence after 6 months, with researchers noting that the majority of those sufferers (65%) had died by this level.
The research additionally evaluated the proportion of days after discharge spent in numerous care areas and located considerably extra days spent at residence within the efficiently vs. unsuccessfully weaned group (39% vs. 23%), in addition to at rehabilitation (21% vs. 10%). The areas through which unsuccessfully weaned sufferers spent considerably extra days included weaning facilities (26% vs. 15%) and nursing properties (29% vs. 13%).
Of the 25 survivors (36%) who had readmission a minimum of as soon as inside 3 months, considerably extra of those sufferers belonged to the efficiently vs. unsuccessfully weaned group (44% vs. 12%; P = .016). Notably, the proportion of survivors with readmission a minimum of as soon as inside 6 months (n = 32; 46%) didn’t considerably differ between the 2 teams, in keeping with the research.
Researchers additional noticed considerably worse median EuroQol-5 Dimensions-5 Ranges (EQ-5D-5L) index values in unsuccessfully vs. efficiently weaned sufferers at each 3 months (0 vs. 0.41) and 6 months (0 vs. 0.37).
One other measure of health-related high quality of life was quality-adjusted life days, in keeping with the research.
“High quality-adjusted life days have been calculated by multiplying the EQ-5D-5L index worth on the first follow-up with the times alive inside 3 months after discharge and the EQ-5D-5L index worth on the second follow-up with the times alive between 3 and 6 months after discharge,” Paul and colleagues wrote.
Much like above, the median variety of quality-adjusted life days inside 6 months was zero amongst sufferers unsuccessfully weaned, and this was considerably decrease in contrast with the median variety of 73.1 quality-adjusted life days amongst these efficiently weaned (P = .002).
“We analyzed information from a potential, large-scale, cluster-randomized ICU trial; nonetheless, our research had a restricted pattern dimension,” Paul instructed Healio. “Our research emphasizes the significance of weaning success in a affected person’s care trajectory. Thus, future research with potential research designs must be powered to establish determinants of weaning success.”

Perspective
The outcomes of this research affirm earlier findings that PMV is related to vital mortality, discount in high quality of life and decrease probabilities of returning residence. Although not stunning, these findings underscore the significance of early ventilator liberation, and extra importantly, stopping initiation of invasive mechanical air flow (IMV) every time doable.
On this research, the authors used the clinically accepted definition of PMV, together with sufferers who had been endotracheally intubated/tracheostomy on IMV for larger than or equal to 21 days. At this period, vital common deconditioning happens, usually associated to immobility together with ventilator-induced diaphragmatic dysfunction (VIDD), each negatively impacting weaning success. These sufferers are additionally in danger for growing ventilator-associated problems resembling pneumonia, in addition to immobility-associated problems resembling venous thromboembolism and strain ulcers. Whereas these weren’t reported on this research, they could have been a consider affected person consequence.
Sufferers who require IMV usually stay within the acute care setting, since many long-term care and rehabilitation services are usually not able to caring for ventilated sufferers. For individuals who transition to those services, the bulk did not wean and continued to expertise poor high quality of life. On this research the provision of ventilator weaning services was a novel useful resource not obtainable in lots of nations.
In my expertise, IMV is initiated in sufferers presenting emergently with acute respiratory failure, usually with little or no time to debate potential problems or medical trajectory with the affected person or household. As soon as initiated, the objective must be to liberate the affected person from IMV as rapidly as doable. Most often, this may be achieved, however for some sufferers with extreme traumatic mind damage, acute respiratory misery syndrome and underlying continual pulmonary illness, I anticipated an extended course of IMV. Beneath this circumstance, our focus was to work towards ventilator liberation whereas stopping problems. In some circumstances, efficiency of early tracheostomy was useful in earlier weaning.
This research underscores the significance of stopping PMV via implementation of evidence-based methods for ventilator liberation and limiting initiation of IMV in circumstances the place it is probably not useful. Implementation of the ABCDEF, or A-F, bundle together with early and sustained mobility is crucial to stop generalized affected person deconditioning, VIDD, infectious and immobility-associated problems. Most often, clinicians don’t “resolve” to provoke a course of PMV. Moderately, it’s the results of a protracted sickness/complication. Nevertheless, for these sufferers the place PMV could also be anticipated resulting from underlying continual illness, the affected person, their surrogate and household must be supplied with practical outcomes to permit knowledgeable selections about initiation of IMV.
From this necessary analysis, additional research ought to concentrate on figuring out patient-specific components that lead to PMV, in addition to patient-ventilator interactions that will contribute to PMV. The ability of AI could also be useful in evaluating giant datasets to seek out these patterns. AI-based methods might extra quickly establish modifications in affected person pulmonary mechanics to assist stop ventilator-induced lung damage, as nicely establish and resolve patient-ventilator dyssynchrony. Moreover, ongoing analysis of air flow and physiologic parameters by AI methods could higher acknowledge affected person readiness for ventilator liberation.
