Solid-organ transplantation has emerged as one of the most significant medi
cal advances in the management of end-stage organ disease to date. However,
a long term successful outcome after transplantation relies heavily upon t
he extended, if not lifelong, intake of immunosuppressive medication. Nonco
mpliance with the medication regimen may have devastating effects on the gr
aft and the patient. Furthermore, the effects of noncompliance place an add
itional burden on the medical resources available and the already scarce or
gan supply. The magnitude of post-transplant noncompliance and factors asso
ciated with noncompliance with various immunosuppressant drugs are reviewed
. Patient, physician, social and family relationships interact in a complex
manner in the post-transplant scenario and problems here could underlie no
ncompliance. The paper also includes a review of the methods of evaluating
and monitoring noncompliance. Preventive and remedial measures that may hel
p the transplant team to effectively manage this problem are suggested. The
multidisciplinary nature of post-transplant patient management and the nee
d for a cohesive approach toward the patient is emphasised. With the identi
fication of patients at higher risk for noncompliance, close monitoring and
early intervention, it may be possible to effectively control the effects
of noncompliance until newer strategies are developed which permit immunosu
ppression-free transplantation.
