Patient adherence is vital to the success of durable mechanical circulatory support (MCS), and the pre-MCS assessment of adherence by the multidisciplinary advanced heart failure team is a critical component of the evaluation. We assessed the impact of a high-risk psychosocial assessment before durable MCS implantations on post-MCS outcomes. Between January 2010 and April 2018, 319 patients underwent durable MCS at our center. We excluded those who died or were transplanted before discharge. The remaining 203 patients were grouped by pre-MCS psychosocial assessment: high-risk (26; 12.8%) versus acceptable risk (177; 87.2%). We compared clinical characteristics, nonadherence, and outcomes between groups. High-risk patients were younger (48 vs. 56; p = 0.006) and more often on extracorporeal membrane oxygenation at durable MCS placement (26.9% vs. 9.0%; p = 0.007). These patients had a higher incidence of post-MCS nonadherence including missed clinic appointments, incorrect medication administration, and use of alcohol and illicit drugs. After a mean follow-up of 15.3 months, 100% of high-risk patients had unplanned hospitalizations compared with 76.8% of acceptable-risk patients. Per year, high-risk patients had a median of 2.9 hospitalizations per year vs. 1.2 hospitalizations per year in acceptable-risk patients. While not significant, there were more driveline infections over the follow-up period in high-risk patients (27% vs. 14.7%), deaths (27% vs. 18%), and fewer heart transplants (53.8% vs. 63.8%).The pre-MCS psychosocial assessment is associated with post-MCS evidence of nonadherence and unplanned hospitalizations. Attention to pre-MCS assessment of psychosocial risk factors is essential to optimize durable MCS outcomes.
