Out of the Fire, Into the Fog: Association Between Early Mechanical Ventilation and Delirium in Hospitalized Burn Patients.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction Delirium is a common and clinically significant complication among hospitalized burn patients, associated with increased morbidity, mortality, and healthcare utilization. While multiple factors contribute to delirium risk, mechanical ventilation has been associated with delirium, although this relationship may reflect underlying illness severity and ICU-level treatment exposure. However, large-scale, multicenter administrative analyses comparing coded outcomes between mechanically ventilated and non-ventilated burn patients remain limited. Methods A retrospective cohort study was conducted using the TriNetX (TriNetX, LLC, Cambridge, Massachusetts, United States) database to identify adult hospitalized burn patients with International Classification of Diseases (ICD)-coded burns involving ≥20% total body surface area. Patients were stratified into two cohorts based on receipt of mechanical ventilation within five days of the index burn event. Exclusion criteria included age <18 years and diagnoses of dementia, Alzheimer's disease, substance use disorders, or other conditions associated with baseline cognitive impairment. Cohorts were propensity score matched for age, sex, race, ethnicity, ICD-coded burn extent history, hypertension, diabetes, ischemic heart disease, sepsis, inhalation injury, and respiratory disorders. Outcomes assessed within 30 days included administratively documented delirium, disorientation, mortality, anxiety disorders, depressive disorders, and acute stress-related disorders. Results There were 1,541 patients in each cohort after matching. Ventilated patients had higher rates of administratively documented delirium (risk ratio (RR): 2.16, 95% CI: 1.51-3.09, p<0.0001), mortality (RR: 5.06, 95% CI: 4.23-6.05, p<0.0001), anxiety disorders (RR: 1.88, 95% CI: 1.58-2.21, p<0.0001), disorientation (RR: 3.39, 95% CI: 2.27-5.06, p<0.0001), and acute stress-related disorders (RR: 1.77, 95% CI: 1.40-2.22, p<0.0001). Depressive disorders were not significantly different between cohorts (RR: 1.42, 95% CI: 0.85-2.39, p=0.19). Discussion Early mechanical ventilation was associated with higher rates of administratively documented delirium, mortality, anxiety disorders, disorientation, and acute stress-related disorders among adult hospitalized burn patients. However, these findings likely reflect both ICU-level treatment exposure and substantial residual confounding by underlying illness severity. Early mechanical ventilation may identify a high-risk subgroup that warrants structured neurocognitive monitoring, psychological screening, sedation-conscious care, and post-extubation support. Given the observational design and reliance on administrative coding, these findings should be interpreted as hypothesis-generating.
