BACKGROUND Dysphagia following extubation is common in intensive care unit (ICU) patients. Diagnosing postextubation dysphagia allows identification of patients who are at highest risk for aspiration and its associated adverse outcomes. Older adults an increased complications due to multiple comorbidities, a higher baseline dysphagia, pneumonia. OBJECTIVES We aimed investigate the association between 1‐year mortality older Secondary outcomes included ICU hospital lengths stay, readmission,...

Early mobility interventions in the intensive care unit can improve patients' outcomes, yet they are not routinely implemented many units. In an effort to identify opportunities implement and sustain evidence-based practice, prior work has demonstrated that understanding decision-making process of health professionals is critical for identifying program implementation. Nurses often responsible mobilizing patients, but how overcome barriers make decisions mobilize patients understood.To...
