BACKGROUND: Renal replacement therapies which consist of renal transplantation
and dialysis are the only treatment options for patients with terminal renal
failure. These therapies have changed the outcome from being fatal to being a
chronic disease. Kidney transplantation involves the use of immunosuppressive
agents to prevent rejection. Currently, several immunosuppressive agents have
shown efficacy, safety, and different costs.
OBJECTIVE: The aim was to evaluate the cost-effectiveness of early conversion
from tacrolimus to mammalian target of rapamycin inhibitors sirolimus or
everolimus versus continuous treatment with tacrolimus among renal transplantat
patients in Colombia.
METHODS: We performed systematic literature review to extract data for clinical
effectiveness and safety of tacrolimus replacement schemes for immunosuppressive
therapy in renal transplantation in adults. A Markov model in TreeAge was
developed, simulating the patient's natural history with renal transplantation.
The perspective of the Colombian Health System was used, including only direct
costs. The cost-effectiveness ratio and incremental cost-effectiveness ratio were
estimated. Deterministic and probabilistic sensitivity analyses were performed. A
5% discount rate was applied in costs and health results.
RESULTS: Results for the replacement of tacrolimus to sirolimus are provided. The
cost per year of additional life gained for sirolimus was Col$2,441,171.43; the
cost for avoided loss was Col$4,014,152.84. The acceptability curve shows that a
strategy with sirolimus is the most cost-effective one.
CONCLUSIONS: This study suggested that the sirolimus strategy is cost-effective
in Colombia for patients with renal transplantation using as threshold less than
three times the gross domestic product (GDP) per capita of Colombia per life of
years gained.

Abstract
BACKGROUND
Renal replacement therapies which consist of renal transplantation and dialysis are the only treatment options for patients with terminal renal failure. These therapies have changed the outcome from being fatal to being a chronic disease. Kidney transplantation involves the use of immunosuppressive agents to prevent rejection. Currently, several immunosuppressive agents have shown efficacy, safety, and different costs.OBJECTIVE

We performed systematic literature review to extract data for clinical effectiveness and safety of tacrolimus replacement schemes for immunosuppressive therapy in renal transplantation in adults. A Markov model in TreeAge was developed, simulating the patient's natural history with renal transplantation. The perspective of the Colombian Health System was used, including only direct costs. The cost-effectiveness ratio and incremental cost-effectiveness ratio were estimated. Deterministic and probabilistic sensitivity analyses were performed.

This study suggested that the sirolimus strategy is cost-effective in Colombia for patients with renal transplantation using as threshold less than three times the gross domestic product (GDP) per capita of Colombia per life of years gained.Links
