BAD MEDICINE Arnold S. Relman says our current health care system is in critical condition ("The Health of Nations," March 7). Unfortunately, his article failed in both its diagnosis and its prescription. He critiques the deficiencies in our system but proposes a utopian solution that could never exist. Although his model has been attempted and is currently in place in Canada, he neglects to examine its real world results. In Canada, my home country, patients must wait months for procedures that are available in days in the United States, thanks to Canada's single-payer system.
