Outcomes of acute inpatient rehabilitation of patients with left ventricular assist devices.

OBJECTIVE

To investigate the benefits of comprehensive inpatient rehabilitation for patients after left ventricular assist device (LVAD) implantation.

DESIGN

A retrospective cohort study.

SETTING

An urban academic inpatient rehabilitation hospital.

PATIENTS: This study included 58 patients admitted to inpatient rehabilitation after LVAD implantation between 2009 and 2012.

METHODS

Chart review of demographic, clinical, and functional data for patients admitted to inpatient rehabilitation after LVAD implantation was performed.

MAIN OUTCOME MEASUREMENTS: Length of stay, admission and discharge Functional Independence Measure (FIM), and FIM efficiency.

RESULTS

The study included 47 male and 11 female patients ages 21.8-84.1 years (mean [standard deviation {SD}], 64.2 ± 11.2 years). The mean (SD) length of time between LVAD implantation and admission to rehabilitation was 27.0 ± 15.3 days. Twenty-one patients (36%) required transfer to an acute care hospital. Ten patients returned after transfer and completed inpatient rehabilitation. For the 47 total patients who completed inpatient rehabilitation, the mean (SD) length of stay was 20.3 ± 10.8 days (range, 7-50 days). Mean (SD) admission and discharge FIM scores were 68.4 ± 13.6 and 91.7 ± 11.8, respectively, with a mean (SD) difference between admission and discharge FIM scores of 23.4 ± 11.2. The mean (SD) FIM efficiency was 1.33 ± 0.65. Complications during rehabilitation included anemia that required transfusion, respiratory distress, epistaxis, gout flare, automated implantable cardioverter defibrillator firing, and gastrointestinal bleeding.

CONCLUSIONS

Patients with LVADs demonstrate functional gains in inpatient rehabilitation. However, there is a high incidence of complications in this population, which often requires transfer to an acute care setting.
