Trends in primary prescribing outcomes, comparing early PDMP registrants and matched non-registrants. Data are means per prescriber.^a

^a Data are based on GEE models adjusted for urban or rural location of the prescriber. Error bars are 95% confidence intervals. T0 through T16 represent 2-month time intervals beginning with October and November, 2011. Inappropriate opioid prescriptions are those where a second prescription with the same drug name, from a different prescriber, was filled within 7 days of a first prescription that contained ≥30 pills. A “multiple provider episode” refers to a patient with ≥ 3 opioid prescribers in the 2 month interval
