Background/Introduction
Mobilization of critically ill patients in the intensive care unit (ICU) is associated with improved function at hospital discharge and reduced duration of mechanical ventilation (MV). Few studies, however, focus on physical therapy (PT) in patients on prolonged mechanical ventilation (PMV) despite their high risk of immobility and poor outcomes.
Objective/Aims
To identify factors associated with the receipt of PT consultation among patients requiring PMV. We hypothesized that key factors including age, severity of illness and presence of a tracheostomy are associated with PT consultation.
Methods
Retrospective cohort study of adults on MV for ≥14 days for acute respiratory failure at an academic medical center. Primary outcome was PT consultation by day 14 of MV. We examined associations between the following key predictors, chosen a priori, and PT consultation: age, tracheostomy, illness severity, oxygenation status, shock, hemodialysis and medical service using multivariable logistic regression. Wilcoxon rank sum testing was used to test relationship between sedation and PT.
Results
We identified 175 patients requiring PMV at our institution. Most were middle-aged (mean 49.7, SD 18.5) men (65%) with high illness severity (mean APACHE III 86, SD 40). Less than half of all patients requiring PMV (78/175, 45%) received PT consultation in the ICU and most failed to progress with therapy beyond range of motion exercises (86%). Failure to progress was associated with level of sedation (med Ramsay score 4.5 [IQR 3–6] v 3.5 [IQR 3–5], p=0.01). Presence of a tracheostomy and pre-hospital non-ambulatory status were associated with receipt of PT by day 14 of MV (OR 6.94 and 3.42 respectively, p=≤0.05).
Conclusions
In our study, we found that PT for PMV patients occurs infrequently and is generally of low intensity. Level of sedation, presence of a tracheostomy and pre-hospital non-ambulatory status were associated with receipt of PT consultation by day 14 of MV.
