Background/aim: Invasive mechanical ventilation (IMV) is a fundamental intervention for patients with respiratory failure in intensive care units (ICUs). This nationwide, multicenter point-prevalence study aimed to describe current mechanical ventilation mode preferences (conventional, adaptive, and biphasic) in Turkish ICUs and to report associated clinical outcomes descriptively, without assessing causal relationships. Materials and methods: A nationwide, multicenter point-prevalence study was conducted on 17 April 2024 and included adult patients (>= 18 years) who had been receiving IMV for more than 24 h. Data on patient demographics, ventilation mode distribution, ventilatory parameters, and descriptive clinical outcomes on day 28 (weaning status, tracheostomy, and mortality) were recorded without comparative outcome analysis. Results: A total of 426 patients were included. Conventional modes were used in 84.5% of patients, adaptive modes in 10.6%, and biphasic modes in 4.9%. Synchronized intermittent mandatory ventilation (SIMV) was the most commonly used conventional mode. The primary indication for IMV was acute respiratory failure (61%), with pneumonia being the leading cause. Among the 350 orotracheally intubated patients, 25.6% were in the weaning phase on the study day. A total of 59 (16.9%) patients were extubated, 150 (42.9%) underwent tracheostomy, and 64 (18.2%) remained intubated on day 28. Overall, 185 (43.4%) patients died during their ICU stay, 152 (35.7%) remained in the ICU, and 89 (20.9%) were successfully discharged from the ICU. Conclusion: Conventional ventilation modes, particularly SIMV, were more commonly used in Turkish intensive care units (ICUs), whereas adaptive modes were less frequently applied. These patterns may reflect factors such as clinician familiarity, institutional practices, and equipment availability rather than definitive preferences. Although the impact of ventilation modes on clinical outcomes was not comparatively evaluated in this study, the choice of ventilation mode may still influence patient outcomes. Therefore, further prospective and comparative studies are warranted to better elucidate this relationship.

Objective: Vaccination against severe acute respiratory syndrome coronavirus-2 (SARS-2) prevents the development of serious diseases has been shown in many studies. However, the effect of vaccination on outcomes in COVID-19 patients requiring intensive care is not clear.Methods: This is a retrospective multicenter study conducted in 17 intensive care unit (ICU) in Turkey between January 1, 2021, and December 31, 2021. Patients aged 18 years and older who were diagnosed with COVID-19 and followed in ICU were included in the study. Patients who have never been vaccinated and patients who have been vaccinated with a single dose were considered unvaccinated. Logistic regression models were fit for the two outcomes (28-day mortality and in-hospital mortality).Results: A total of 2968 patients were included final analysis. The most of patients followed in the ICU during the study period were unvaccinated (58.5%). Vaccinated patients were older, had higher Charlson comorbidity index (CCI), and had higher APACHE-2 scores than unvaccinated patients. Risk for 28-day mortality and in-hospital mortality was similar in across the year both vaccinated and unvaccinated patients. However, risk for in-hospital mortality and 28-day mortality was higher in the unvaccinated patients in quarter 4 adjusted for gender and CCI (OR: 1.45, 95% CI: 1.06-1.99 and OR: 1.42, 95% CI: 1.03-1.96, respectively) compared to the vaccinated group.Conclusion: Despite effective vaccination, fully vaccinated patients may be admitted to ICU because of disease severity. Unvaccinated patients were younger and had fewer comorbid conditions. Unvaccinated patients have an increased risk of 28-day mortality when adjusted for gender and CCI.
