Early Mobilization in People With Acute Cardiovascular Disease.

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.

Level of function mobility scale for nurse-driven early mobilisation in people with acute cardiovascular disease.

BACKGROUND: There are currently no validated tools that are reliable and easy to use for nurses to assess mobility in people with acute cardiovascular disease in the Cardiovascular Intensive Care Unit (CICU). METHODS: A multidisciplinary team at an academic tertiary care centre developed the Level of Function (LOF) Mobility Scale for use in a nurse-driven early progressive mobilisation in the CICU. To determine inter-rater reliability, the prehospital and admission LOF were assessed independently by two CICU nurses. Pairwise comparisons between raters were evaluated using Cohen's kappa statistic. To determine convergence validity, the LOF and Activity Measure for Post-Acute Care 6-Clicks score upon admission were compared with Spearman's correlation. To determine feasibility, a 9-item mobility scale questionnaire was distributed to CICU nurses with and without experience using the LOF Mobility Scale. The STROBE reporting guidelines were used. RESULTS: The LOF Mobility Scale had good inter-rater reliability for assessment of LOF prior to hospitalisation (N = 131, kappa = 0.66, p < .001) and at the time of CICU admission (N = 131, kappa = 0.71, p < .001). There was a moderate correlation (N = 79 observations; correlation coefficient = 0.525; p < .01) between the bedside nurses LOF and the 6-Clicks score. All nurses surveyed (N = 54; 100%) thought that the LOF Mobility Scale was clear and unambiguous, the LOFs were well-defined and the scale was an appropriate length. Nearly all of the nurses with experience using the scale (N = 22/24; 92%) felt that the scale took less than one minute to complete, compared with about half (N = 14/30; 47%) in the group of nurses without experience using the scale. CONCLUSION: The LOF Mobility Scale is reliable and feasible for mobility assessment in a nurse-driven early progressive mobilisation programme in patients with acute cardiovascular disease in the CICU. RELEVANCE TO CLINICAL PRACTICE: A nurse-driven EM programme can be implemented in the CICU.
