METHODS: Descriptive study of patients admitted to the Ventilator Weaning Program. VOD was queried for selected admission characteristics and outcomes of patients discharged 10/1/2014-12/31/2015. Outcomes (weaned, ventilator-dependent, died) were scored at discharge; weaned defined as patient free of invasive mechanical ventilation for at least one full calendar day prior to day of discharge. Etiology of ventilator dependency (diagnosis leading to initial ICU admission) was determined as per methodology in previous report with six classifications: acute lung disease, chronic lung disease, post-operative, cardiac disease, neurologic disease, and other. Percent of patients in those six categories were compared to historical data from 1988-1991 cohort. Admission characteristics and weaning outcomes for patients in the most recent cohort are reported across the categories.
