PURPOSE: Over the past decade there has been increased attention to the early mobilization of hospitalized patients, including patients with acute respiratory distress or illness. However, there is little evidence to suggest the benefit or feasibility of physical therapy managed mobility with patients who require noninvasive ventilation (NIV). There are a few reported studies which have shown the effectiveness of NIV in exercise training during pulmonary rehabilitation, and the use of bi-level positive airway pressure (BiPAP) on patients who have chronic obstructive pulmonary disease (COPD). At Christiana Care Health System the standard of care since 2012 has been for the physical therapy therapists to mobilize patients with high oxygen requirements using NIV. The purpose of this study is to examine the benefits of early mobilization using noninvasive ventilation.

METHODS: To qualify for the NIV progam patients had to be: > 18years, ambulatory at baseline, and with documentation of desaturation (<88%) during routine physical therapy requiring 100% oxygen. Patients admitted to the Christiana Hospital on the pulmonary stepdown and medical intensive care unit (MICU) from 2012 to 2014, who were clinically eligible for NIV treatment and participated in routine physical therapy with close respiratory monitoring were included in the analysis. The control group consisted of successive patients with similar entry criteria and admitted between 2011 and 2012. Wilcoxon-rank sum test was used to compare change in ambulation distance from first to last trial and maximum ambulation distance between patients in the NIV program and controls. Linear regression was used to adjust for potential confounders. Because of the skewed distributions, all variables were transformed using a Box-Cox transformation

RESULTS: The final dataset included 17 patients in the NIVprogram and 64 historic controls. The median ages for the NIV and control groups were 70.0 and 72.5 years, respectively. A total of 71% of the NIV patients and 91% of the controls were white and 29% of the NIV and 69% of the controls were female. The median change in ambulation distance from first trial to last trial was 125 ft in the intervention group as compared to 0 ft in the control (p<0.001) and remained significant after adjusting for first ambulation distance, age, gender and race. The median maximum ambulation throughout all sessions in the intervention group was 300 ft as compared to 65 ft in the control group (p<0.001) and remained significant after adjusting for confounders. Ten out of 17 (59%) patients in the intervention group were discharged home compared to 50% of the control group (p=0.5). No adverse events occurred.

CONCLUSIONS: There was a significant change in ambulation distance from first to last sessions in patients who used NIV. Additionally the maximum ambulation distance was significantly higher in patients who used NIV

CLINICAL IMPLICATIONS: The use of NIV in routine physical therapy with patients who have high oxygen requirements appears to be safe and effective. Further research is needed to confirm the efficacy of NIV in routine early mobilization. As well as the effect on length of stay, long term functional outcome, and discharge disposition.
