Abstract

Objectives

We evaluated the reliability of the Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) in heart transplant (HT) recipients and explored its usefulness in predicting post-transplant outcomes.

Background

Pre-transplant psychosocial and behavioral risk is associated with post-transplant clinical outcomes. SIPAT is a risk assessment tool created for pre-transplant psychosocial evaluation.

Methods

Via retrospective chart review, three examiners applied the SIPAT to 51 adult HT recipients. Examiners blinded to SIPAT scores extracted data and interviewed clinicians for one-year post-transplant outcomes. Analysis included Intra-class correlation coefficient (ICC), Pearson's correlation coefficient and Chi-square.

Results

SIPAT demonstrated strong inter-rater reliability (ICC = 0.89, 95% CI = 0.76–0.96). Compared to those with SIPAT ratings of “Excellent/Good”, the “Minimally Acceptable Candidate/High Risk” group was more likely to miss clinic visits (p = 0.004).

Conclusions

The SIPAT tool had strong IRR. Less favorable SIPAT ratings were associated with nonadherence to clinic visits. Further study is warranted to determine association of SIPAT ratings to clinical outcomes.
