In the intensive care unit (ICU), extubation failure has been associated with greater resource utilization and worsened clinical outcomes. Most recently, nighttime extubation (NTE) has been reported as a risk factor for increased ICU and hospital mortality. We hypothesized that, in a large, urban, university-affiliated hospital with multidisciplinary assessment for extubation, rigorously protocolized extubation algorithms, and expert airway managers available at all times of day for assessment of high-risk extubations, NTE would not confer additional risk of adverse clinical outcomes.
This was a retrospective cohort study of mechanically ventilated adults at a single university-affiliated hospital. NTE was defined as occurring between 7:00 PM and 6:59 AM the following day. All data were extracted from the institution's electronic medical record. Multi-vari-able regression analyses were used to assess associations between NTE and reintubation, ICU and hospital length of stay (LOS), and mortality with adjustments for demographic and clinical covariates defined a priori. Palliative, unplanned, and routine postoperative extubations were excluded in sensitivity analyses.
Of 2241 patients, 204 of 2241 (9.1%) underwent NTE. The rates of reintubation (NTE 6.9% versus daytime extubation [DTE] 12.4%; adjusted odds ratio [95% confidence interval {CI}], 0.78 [0.43-1.41]; P = .41) and in-hospital mortality (NTE 3.4% versus DTE 5.9%; adjusted odds ratio [95% CI], 0.72 [0.28-1.84]; P = .49) were not found to differ. NTE, compared to DTE, was associated with shorter duration of mechanical ventilation (median [interquartile range], 1 [0-1] days vs 2 [1-4] days; adjusted ratio of geometric means [RGMs] [95% CI], 0.64 [0.54-0.70]; P < .001), ICU (2 [1-5] days vs 4 [2-10] days; adjusted RGMs [95% CI], 0.65 [0.57-0.75]; P < .001), and hospital LOS (6 [3-18] days vs 13 [6-25] days; adjusted RGMs [95% CI], 0.64 [0.56-0.74]; P < .001). These results were unchanged in sensitivity analyses.
Patients who underwent NTE were not at increased risk of reintubation or in-hospital mortality. In addition, NTE was associated with a shortened duration of mechanical ventilation and hospital LOS. In health care systems with similar critical care delivery models, NTE may coincide with reduced resource utilization in appropriately selected patients.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 22. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 29 March 2023.
All research outputs
#2,172,743
of 34,546,575 outputs
Outputs from Anesthesia and analgesia
#520
of 11,030 outputs
Outputs of similar age
#36,330
of 393,627 outputs
Outputs of similar age from Anesthesia and analgesia
#12
of 116 outputs
Altmetric has tracked 34,546,575 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 93rd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 11,030 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.8. This one has done particularly well, scoring higher than 95% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 393,627 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 90% of its contemporaries.
We're also able to compare this research output to 116 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 89% of its contemporaries.
