Background. The burgeoning influence of managed care in transplantation, co
upled with a shrinking health-care dollar, has placed most transplant progr
ams under intense pressure to cut costs. We under-took a retrospective cost
-identification analysis to determine what clinical variables influenced fi
nancial outcomes after orthotopic cadaver liver transplants (OLTx).
Methods. Fifty patients receiving 53 transplants between April 1995 and Nov
ember 1996 were reviewed. Clinical data were obtained from our institution'
s transplant database, and total costs (not charges) for the transplant adm
ission and the 6 months after transplant were obtained with use of an activ
ity-based cost accounting system (HBOC Trendstar, Atlanta, Ga).
Results. The average total cost of second transplants (n = 5) was $97,262 g
reater than for first transplants (n = 48, P < .05). Patients transplanted
initially as United Network for Organ Sharing (UNOS) status 2 (n = 20) incu
rred average costs that were $51,762 higher than for patients transplanted
as UNOS status 3 (n = 28, P = .008). Patients with a major bacterial or fun
gal infection (n = 28) incurred average costs $46,282 higher than recipient
s who were infection free (n = 22, P = .02). Multivariate analysis demonstr
ated that only length of stay, retransplantation, and postoperative dialysi
s were significantly and independently correlated with costs (r(2) = .605).
When the model was repeated with preoperative variables alone, only UNOS s
tatus was significantly correlated with 6-month total costs (P = .006, r(2)
= .16).
Conclusions. Length of stay is the most important determinant of costs afte
r OLTx. Rational strategies to design cost-effective protocols after OLTx w
ill require further studies to truly define the cost of various morbidities
and outcomes after OLTx.
