THE COST OF ADULT LIVER TRANSPLANTATION IN A REFERRAL CENTER IN SOUTHERN BRAZIL.

BACKGROUND

Liver transplantation (LTx) is the primary and definitive treatment of acute or chronic cases of advanced or end-stage liver disease. Few studies have assessed the actual cost of LTx categorized by hospital unit.

OBJECTIVE

To evaluate the cost of LTx categorized by unit specialty within a referral center in southern Brazil.

METHODS

We retrospectively reviewed the medical records of 109 patients undergoing LTx between April 2013 and December 2014. Data were collected on demographic characteristics, etiology of liver disease, and severity of liver disease according to the Child-Turcotte-Pugh (CTP) and Model for End-stage Liver Disease (MELD) scores at the time of LTx. The hospital bill was transformed into cost using the full absorption costing method, and the costs were grouped into five categories: Immediate Pretransplant Kit; Specialized Units; Surgical Unit; Intensive Care Unit; and Inpatient Unit.

RESULTS

The mean total LTx cost was US$ 17,367. Surgical Unit, Specialized Units, and Intensive Care Unit accounted for 31.9%, 26.4% and 25.3% of the costs, respectively. Multivariate analysis showed that total LTx cost was significantly associated with CTP class C (P=0.001) and occurrence of complications (P=0.002). The following complications contributed to significantly increase the total LTx cost: septic shock (P=0.006), massive blood transfusion (P=0.007), and acute renal failure associated with renal replacement therapy (dialysis) (P=0.005).

CONCLUSION

Our results demonstrated that the total cost of LTx is closely related to liver disease severity scores and the development of complications.
