Doctors would be required to check up on most patients before prescribing opioid painkillers under a legislative proposal that will get a warm reception at a Capitol rally on Tuesday. From there, it may face a tougher reception from physicians who view it as overkill and a crimp on their ever-shrinking amount of time to treat patients.

But national research suggests that requiring physicians to check state registries of patients’ drug histories can help curb the painkiller epidemic by identifying patients who are abusing opioids and “shopping” among doctors for prescriptions.
