PURPOSE: To provide an evidence-based approach to the formulation of
clinical policy with respect to allogeneic bone marrow transplantation
(BMT) that involves perceived trade offs between two major factors: costs
and consequences. The report also highlights key informational
deficiencies. PATIENTS AND METHODS: Adults with acute myeloid leukemia
(AML) in second complete remission (2CR) and those with acute lymphoblastic
leukemia (ALL) in first complete remission (1CR) were assigned to BMT or
control groups solely on the availability of a suitable donor. All
hospital-borne costs were estimated, based on services used according to
manual chart review, in four categories: diagnostic and therapeutic costs,
professional fees, drug costs, and ward costs. Incremental costs and
incremental life-years were calculated, and the quotient determined a cost
per life-year gained by BMT for AML (2CR) and ALL (1CR). RESULTS: The
incremental cost (in 1992 Canadian dollars) per life-year gained by BMT
(cost-effectiveness) for AML (2CR) was $29,200; and for ALL (1CR) it was
minus $29,200. CONCLUSION: For AML (2CR), allogeneic BMT creates better
outcomes than standard treatment, but is more costly. For ALL (1CR), both
the costs and outcomes are similar for BMT and standard therapy. Quality
adjustments made to life-years gained did not change these conclusions.
