Key result
Five years after coronary artery bypass graft surgery, patients reported significantly higher mental health quality of life scores compared to their spouses' proxy assessments (54.8 vs 47.7, p<0.001).
Why the study?
Can spouses accurately report the physical and mental health-related quality of life of patients five years after CABG surgery?
Cross-Sectional (n=56)
No
Can spouses accurately report the physical and mental health-related quality of life of patients five years after CABG surgery?
Spouses can accurately assess the physical quality of life of CABG patients five years post-surgery, but they significantly underestimate the patients' mental health.

Spouses underestimate mental health QoL post-CABG; leaves open proxy reliability for clinical assessments and long-term observational research.
Health-related quality of life (HRQoL) was examined in patients' and their respective spouses' perspectives five years after cardiac bypass surgery. Participants completed the Short-Form 36 (SF-36) which consists of eight domains and two component summary scores measuring physical and mental HRQoL (PCS and MCS respectively). Paired t tests were used to compare couples responses (n=56 pairs) with spouses recording higher (i.e. better scores) in the physical-related domains although differences were not significant. Statistically significant results were found between patients and spouses in emotional role, mental health, social functioning, energy/vitality and general health perceptions (p< 0.001). The PCS were very similar for both the patient and spouses sample (45.9 v. 45.8 respectively, p = .829) and the MCS was significantly higher in the patients compared to the spouses (54.8 v. 47.7, p < .001). The results demonstrated that spouses could accurately report the physical aspects of HRQoL but not the mental health of their partner.

Geraldine Lee (2008) conducted a cross-sectional in Coronary Artery Bypass Graft Surgery (CABGS) (n=56). Patient self-report vs. Spouse proxy report was evaluated on Mental Component Summary (MCS) score on the SF-36 (p=<0.001). Five years after coronary artery bypass graft surgery, patients reported significantly higher mental health quality of life scores compared to their spouses' proxy assessments (54.8 vs 47.7, p<0.001).
