Addressing the functional needs of left ventricular assist device candidates: Development and feasibility of an...

Everyday living with a left ventricular assist device (LVAD) is complex, particularly for people with physical or cognitive impairments or limited social supports. There is a need for standardized pre-operative functional evaluations.

Our objectives were to describe a pre-operative occupational therapy (OT) evaluation for LVAD candidates, assess its feasibility in routine care, and characterize functional needs.

We retrospectively reviewed electronic medical records of pre-operative OT consultations for LVAD candidates over four years (n = 209). Occupational profile, vision, and sensation were operationalized from documentation narratives. Daily functioning was measured with Activity Measure for Post-Acute Care, grip strength with dynamometer, cognition with Montreal Cognitive Assessment and Allen Cognitive Level Screen-5, and LVAD self-management with a performance-based ordinal scale.

89.5 % of consultations were completed, averaging 61.2 min (n = 187): 79.1 % (148/187) inpatient and 20.9 % (39/187) outpatient. Patients completed 87.7 % (164/187) to 100.0 % (187/187) of evaluation components. 21.9 % (41/187) of candidates lived alone. 6.4 % (12/187) and 7.0 % (13/185) had visual and sensory dysfunction. 57.4 % were independent with daily activities (104/181). 17.7 % (32/181) had impaired grip strength. 69.3 % (124/179) had impaired cognition, 29.7 % (51/172) with impaired functional cognition for everyday activities. 88.4 % (145/164) required physical or cueing assistance while practicing LVAD batteries management. OTs interpreted that 20.9 % (39/187) would likely require 24/7 post-operative support with LVAD self-care.

Pre-operative OT evaluations were feasible and emphasized complex functional needs. Assessing LVAD self-care abilities may inform candidacy and facilitate early interventions to optimize functioning. OT should be consulted within interprofessional teams for all LVAD candidates.
