Abstract

Background: Appropriate collection of quality of life measurements for left ventricular assist device (LVAD) patients is challenging. Patient-Reported Outcomes Measurement Information System (PROMIS) is a popular tool that has been validated across multiple disciplines, but its applicability to the LVAD population remains unknown.

Methods: This single-center, retrospective review included LVAD patients who completed a PROMIS assessment and Kansas City Cardiomyopathy Questionnaire (KCCQ-12) survey at clinical encounters postoperatively. Patients completed computer adaptive PROMIS assessments for physical function, pain interference, and depression. All PROMIS domains are designed to follow a normal distribution (mean T-score 50, SD 10) in the general population. Assessments were aggregated over time and correlation between the KCCQ-12 summary score and each PROMIS domain was assessed individually.

Results: A total of 178 LVAD patients were included in the study. The median time between LVAD implantation and PRO collection was 16.5 [interquartile range, 7.9-37.8] months. Patients typically had worse physical function (T-score 38.8 [33.6-44.2]) but comparable pain (51.1 [38.7-59.2]) and depression (49.9 [41.7-57.5]) as the general population. The KCCQ-12 was more strongly correlated to PROMIS physical function (Spearman's ρ = 0.746) than pain (ρ = -0.539) or depression (ρ = -0.591).

Conclusions: PROMIS provides a robust quality of life data collection system that can be implemented in a clinical setting without imposing a significant burden. Using this more holistic system may allow for better patient-centered care in order to address quality of life limitations imposed by LVAD support that are not directly related to heart failure symptoms.
