Patient-Reported Outcomes Measurement Information System (PROMIS) in Left Ventricular Assist Devices

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 post-operatively. 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 rho = 0.746) than pain (rho = -0.539) or depression (rho = -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.

Automated summary

Collecting quality of life measurements for LVAD patients can be challenging. This study found that PROMIS is a robust data collection system that can be implemented in a clinical setting, allowing for better patient-centered care and addressing quality of life limitations imposed by LVAD support.
