Physician-approved protocols increase naloxone dispensing rates

To measure the impact of the implementation of a law that allows pharmacists to provide naloxone under a physician-approved protocol on naloxone dispensing rates in an all-payer population across the United States.

Prescription claims from a national grocery chain for 31 states and Area Heath Resource File were used for this retrospective study. The study sample included all patients who filled at least one naloxone prescription during the study period from July 16, 2014 to January 16, 2017. A stepwise autoregression was performed for 30 consecutive months to evaluate the change in naloxone prescription dispensing rate. The primary independent variable was "implementation of the physician-approved protocol." The primary outcome measure was the rate of naloxone prescriptions dispensed per month per state. Secondary outcome measures were naloxone dispensing rates by each payer.

Number of patients who received naloxone prescriptions in the states with physician-approved protocol was 423% higher compared to states without the protocol. The overall model showed that the naloxone dispensing rate was 6 times higher in the states with a physician-approved protocol. In the payer-based models, comparing states with and without protocol, the dispensing rate was highest for Medicare (9.0 times) followed by Private (4.6 times), Medicaid (3.2 times), and Cash (3.1 times). The number of prescriptions dispensed in the low-employment states with the protocol was 17.59 times higher compared to states without the protocol.

Implementation of physician-approved protocol was strongly associated with an increase in naloxone dispensing rates, especially in the low-employment states.
