Xu J, Chen J, Cai H, Zheng X. Effect of timing of intubation on clinical outcomes of patients with septic shock: a retrospective cohort study. Sci Rep 2024; 14:22128. [PMID: 39333262 PMCID: PMC11436761 DOI: 10.1038/s41598-024-73461-1] [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: 07/12/2024] [Accepted: 09/17/2024] [Indexed: 09/29/2024] Open
Abstract
Evidence-based data regarding the timing of the application of invasive mechanical ventilation among adults with septic shock is insufficient. The guidelines fail to provide clear advice about the optimal time to initiate this support. Consequently, we aimed to investigate whether early intubation could improve survival rates in septic shock patients. We conducted a retrospective analysis of the MIMIC-IV database to evaluate the effectiveness of early intubation on mortality in a cohort of septic shock patients. Adults diagnosed with septic shock, according to the Sepsis-3 definition, were included. They were categorized into an early intubation group (first 8 h after vasopressor initiation) and a non-early intubation group (unexposed). A propensity score matching (PSM) analysis was used to balance the baseline characteristics between the two groups. The primary outcomes were 30-day and 90-day all-cause mortality rates. In addition, we employed the restricted cubic spline to analyze the potential non-linear relationship between the timing of intubation and 30-day or 90-day all-cause mortality. A total of 6864 adult patients, of whom 2048 were intubated in the first 8 h, were evaluated in the final cohort. Following a 1:1 PSM procedure, 2786 patients were successfully paired. At 30 days, 288 of 1393 patients (20.7%) in the early intubation group and 381 of 1393 patients (27.4%) in the non-early intubation group had died (hazard ratio [HR] 0.717; 95% confidence interval [CI] 0.616-0.836; p < 0.001). Similarly, the results also showed that early intubation was associated with a lower 90 day all-cause mortality rate (HR 0.761; 95% CI 0.663-0.874; p < 0.001). Furthermore, ICU and hospital lengths of stay were significantly different between the groups (3.6 [1.9, 7.1] vs. 2.3 [1.3, 4.3]; p < 0.001 and 8.9 [5.4, 15.1] vs. 7.2 [4.5, 12.0]; p < 0.001). In the subgroup analysis, we further confirmed the robustness of our findings. Additionally, we found that the timing of intubation is inversely U-shaped correlated to the 30 day all-cause mortality rate. Among adult patients with septic shock, the early initiation of invasive mechanical ventilation could improve clinical outcomes. The timing of intubation demonstrated an inverse U-shaped association with the 30 day all-cause mortality rate, with the peak risk of death occurring at 50.5 h after septic shock.

Options and opportunities for evidence-informed decision making in the intensive care unit. THE LANCET. RESPIRATORY MEDICINE 2024; 12:642-654. [PMID: 38801827 DOI: 10.1016/s2213-2600(24)00118-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 03/08/2024] [Accepted: 04/05/2024] [Indexed: 05/29/2024]
Abstract
The optimal timing of intubation in acute hypoxaemic respiratory failure is uncertain and became a point of controversy during the COVID-19 pandemic. Invasive mechanical ventilation is a potentially life-saving intervention but carries substantial risks, including injury to the lungs and diaphragm, pneumonia, intensive care unit-acquired muscle weakness, and haemodynamic impairment. In deciding when to intubate, clinicians must balance premature exposure to the risks of ventilation with the potential harms of unassisted breathing, including disease progression and worsening multiorgan failure. Currently, the optimal timing of intubation is unclear. In this Personal View, we examine a range of parameters that could serve as triggers to initiate invasive mechanical ventilation. The utility of a parameter (eg, the ratio of arterial oxygen tension to fraction of inspired oxygen) to predict the likelihood of a patient undergoing intubation does not necessarily mean that basing the timing of intubation on that parameter will improve therapeutic outcomes. We examine options for clinical investigation to make progress on establishing the optimal timing of intubation.

Association between Patient Race and Ethnicity and Use of Invasive Ventilation in the United States. Ann Am Thorac Soc 2024; 21:287-295. [PMID: 38029405 DOI: 10.1513/annalsats.202305-485oc] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Accepted: 11/28/2023] [Indexed: 12/01/2023] Open
Abstract
Rationale: Outcomes for people with respiratory failure in the United States vary by patient race and ethnicity. Invasive ventilation is an important treatment initiated based on expert opinion. It is unknown whether the use of invasive ventilation varies by patient race and ethnicity. Objectives: To measure 1) the association between patient race and ethnicity and the use of invasive ventilation; and 2) the change in 28-day mortality mediated by any association. Methods: We performed a multicenter cohort study of nonintubated adults receiving oxygen within 24 hours of intensive care admission using the Medical Information Mart for Intensive Care IV (MIMIC-IV, 2008-2019) and Phillips eICU (eICU, 2014-2015) databases from the United States. We modeled the association between patient race and ethnicity (Asian, Black, Hispanic, White) and invasive ventilation rate using a Bayesian multistate model that adjusted for baseline and time-varying covariates, calculated hazard ratios (HRs), and estimated 28-day hospital mortality changes mediated by differential invasive ventilation use. We reported posterior means and 95% credible intervals (CrIs). Results: We studied 38,258 patients, 52% (20,032) from MIMIC-IV and 48% (18,226) from eICU: 2% Asian (892), 11% Black (4,289), 5% Hispanic (1,964), and 81% White (31,113). Invasive ventilation occurred in 9.2% (3,511), and 7.5% (2,869) died. The adjusted rate of invasive ventilation was lower in Asian (HR, 0.82; CrI, 0.70-0.95), Black (HR, 0.78; CrI, 0.71-0.86), and Hispanic (HR, 0.70; CrI, 0.61-0.79) patients compared with White patients. For the average patient, lower rates of invasive ventilation did not mediate differences in 28-day mortality. For a patient on high-flow nasal cannula with inspired oxygen fraction of 1.0, the odds ratios for mortality if invasive ventilation rates were equal to the rate for White patients were 0.97 (CrI, 0.91-1.03) for Asian patients, 0.96 (CrI, 0.91-1.03) for Black patients, and 0.94 (CrI, 0.89-1.01) for Hispanic patients. Conclusions: Asian, Black, and Hispanic patients had lower rates of invasive ventilation than White patients. These decreases did not mediate harm for the average patient, but we could not rule out harm for patients with more severe hypoxemia.
