The 90-day clock, as you put it, is very problematic. There have been a number of studies. For example, a Manitoba study actually found that after 90 days of being diagnosed with a major physical impairment, patients reach a peak in their suicidal ideation. They continue to be suicidal, although it wanes, as much as a year later, and thereafter it's still greater than their match cohort, so 90 days is certainly not an opportune waiting time.
The other thing is that we know that it takes a great deal of time for these people to be able to avail themselves of expertise. Patients who are highly at risk, for example those with chronic pain, may have to wait six months or more, depending on what part of the country they happen to live in, in order to get access to care. My specialty is psychiatry. Again, the waiting list for good psychiatric care is in the neighbourhood of months, up to a year, depending on what part of the country you're in.
The 90 days is problematic for all those reasons, which in large measure are data-driven and data-informed.
