I thought you would be interested in my results. DBS generated 4.05 QALYs over a six year periodat a cost of C$83,462 or C$20,607 per QALY. While those are interesting statistics, even more interesting is to cost of doing nothing but carrying on drug therapy - $148,551 or C$65,000 more than DBS. Each QALY generates positive cash flow of $16,000. More to come. Cheers, Bill
