Early Mobilization in People With Acute Cardiovascular Disease

Abstract

Background: Early mobilization (EM) is recommended in critical care units. However, there is little known about EM in people with acute cardiovascular disease.

Methods: Consecutive admissions to a tertiary-care cardiovascular intensive care unit (CICU) before and after implementation of an EM program were reviewed. The Level of Function (LOF) Mobility Scale, which ranges from 0 (bed immobile) to 5 (able to walk >20 m), was used to measure and guide mobility. The primary outcome was discharge home.

Results: There were 1489 patients included in the analysis (preintervention, N = 637; intervention, N = 852). There were no differences in age, sex, or admission for ischemic heart disease (age 68.1 ± 16.1 years; 39.3% female). In the intervention cohort, one-quarter (N = 222; 26.1%) had at least mildly impaired prehospital functional status. The LOF was 4.6 ± 0.7 prehospital, 3.2 ± 1.4 on admission, and 4.2 ± 0.9 on CICU discharge. Half of patients (51.6%) increased their LOF by ≥1 during CICU admission. Nearly all mobility opportunities had a mobility activity (97.0%). The adverse event rate was 0.3% with no life-threatening events, falls, line dislodgements, or health care personnel injuries. The intervention group, compared with the preintervention group, was more likely to be discharged home (83.9% vs 78.3%, P < 0.007) and had a lower rate of in-hospital death (4.2% vs 6.8%; P = 0.04). When adjusted for age, sex, and comorbid illness, admission LOF was a predictor of discharge to health care facility (odds ratio = 0.72; P < 0.001).

Conclusions: EM is safe and feasible in the CICU and effective at increasing discharge home.
