Oregon is debating whether or not to include steroid injections for back pain in their Medicaid coverage. There is a debate among doctors about whether or not steroid injections are useful in treating back pain. Most of the evidence for the effectiveness of the injections is anecdotal and not a result of clinical trials. The argument against clinical trials is that this type of research would require people to volunteer knowing that there was a chance that they would receive a placebo, and there is concern that no one would want to volunteer to receive a shot in the back that might contain only saline or sugar water. It is hoped that steroid injections will replace the need for opioids for some people. A decision has yet to be made.
