If we look at this, this is the total number of people who have pharmacy claim and you can see that about two-thirds of them get a narcotic. What is kind of interesting is that in the orthopedic literature, they’ve looked at how many orthopedic surgeons prescribe narcotics for their patients with various spinal problems. And about 3% of orthopedic patients get narcotics. So I guess that means you go to your primary care physician for the narcotic and not to the orthopedic surgeon. This is obviously a major cost. And the Health Plan is interested to see if they can cut down on the use of narcotics and thereby the amount of money spent of treatment of back pain. This just gives you some sort of local frame work for what happens and how much money we’ve spent on LBP patients.
