Ma. Dew et al., Early post-transplant medical compliance and mental health predict physical morbidity and mortality one to three years after heart transplantation, J HEART LUN, 18(6), 1999, pp. 549-562
Background: Poor medical compliance has been held responsible for a large p
roportion of deaths occurring subsequent to initial postoperative recovery.
However, beyond clinical reports, there has been little empirical examinat
ion of this issue, or of the extent to which major psychiatric disorder and
failure to adjust to the transplant predict long-term physical morbidity a
nd mortality. We prospectively examined whether a full range of compliance
behaviors and psychiatric outcomes during the first year posttransplant pre
dicted subsequent mortality and physical morbidity through 3 years posttran
splant.
Methods: A total of 145 heart recipients who had received detailed complian
ce and mental health assessments during the first year post-transplant were
followed up at 3 years post-transplant. Interview data and corroborative i
nformation from family members were used to determine compliance in multipl
e domains, psychiatric diagnoses, and psychiatric symptomatology during the
first year post-surgery. Medical record reviews were performed to abstract
data on acute graft rejection episodes, incident cardiac allograft disease
(CAD) and mortality from 1 to 3 years posttransplant.
Results: After controlling for known transplant-related predictors of outco
me, multivariate analyses yielded the following significant (p < 0.05) resu
lts: (a) risk of acute graft rejection was 4.17 times greater among recipie
nts who were not compliant with medications; (b) risk of incident CAD was e
levated by persistent depression (Odds Ratio, OR = 4.67), persistent anger-
hostility (OR = 8.00), medication noncompliance (OR = 6.91), and obesity (O
R = 9.92); and (c) risk of mortality was increased if recipients met criter
ia for Post-Traumatic Stress Disorder related to the transplant (OR = 13.74
).
Conclusions: The findings, plus data we have previously reported that showe
d which patients are most likely to have compliance and psychiatric problem
s early posttransplant, suggest that interventions focused on maximizing pa
tients' psychosocial status in these areas may further improve long-term ph
ysical health outcomes in this population.
