ICU sedation, delirium & recovery
Factors associated with oropharyngeal dysphagia 3 months after intensive care unit (ICU) discharge in patients undergoing invasive mechanical ventilation: A post-hoc analysis of a Brazilian multicenter prospective cohort study
Authors' conclusion
OD 3 months after ICU discharge is a common condition among ICU survivors who required IMV. Educational level, severity of illness at ICU admission, ARDS diagnosis at ICU admission, and length of mechanical ventilation are key associated variables.
Study context
- Population
- Adult ICU survivors (age > 18 years) with ICU stay ≥72 h who needed invasive mechanical ventilation, Brazil
- Participants
- 360 survivors
- Primary endpoint
- Incidence of oropharyngeal dysphagia (Functional Oral Intake Scale, structured telephone interviews)
- Follow-up
- 3 months after ICU discharge
Methodological details10 ICUs
- 10 ICUs
Primary result
As reported in the abstract
Incidence of oropharyngeal dysphagia
- Incidence of oropharyngeal dysphagia (OD)
- 24.17%
- Educational attainment, aRR per 1 year increase
- 0.95 (95% CI 0.92-0.99)
- Risk of death at ICU admission, aRR per 1% increase
- 1.99 (95% CI 1.06-3.77)
- ARDS diagnosis at ICU admission, aRR
- 0.21 (95% CI 0.06-0.71)
- Length of mechanical ventilation, aRR per 1 day increase
- 1.02 (95% CI 1.01-1.03)
Secondary outcomes
Physical and mental quality of life (Short Form Health Survey version 2)
- Patients with OD reported significantly worse physical and mental quality-of-life scores
Rehospitalization
- Did not differ significantly between patients with and without OD
