The Times bemoans:
But
now that the center has gotten started, many researchers and economists
are disturbed that it is not using randomized clinical trials, the
rigorous method that is widely considered the gold standard in medical
and social science research. Such trials have long been required to
prove the efficacy of medicines, and similarly designed studies have
guided efforts to reform welfare-to-work, education and criminal justice
programs. But
they have rarely been used to guide health care policy — and experts
say the center is now squandering a crucial opportunity to develop the
evidence needed to retool the nation’s troubled health care system in a
period of rapid and fundamental change.
