Wash. Rev. Code § 70.225.030
To the extent that funding is provided for such purpose through federal or private grants, or is appropriated by the legislature, the health care authority shall study the feasibility of enhancing the prescription monitoring program established in RCW 70.225.020 in order to improve the quality of state purchased health services by reducing legend drug abuse, reducing duplicative and overprescribing of legend drugs, and improving legend drug prescribing practices. The study shall address the steps necessary to expand the program to allow those who prescribe or dispense prescription drugs to perform a web-based inquiry and obtain real time information regarding the legend drug utilization history of persons for whom they are providing medical or pharmaceutical care when such persons are receiving health services through state purchased health care programs.
