The Pew Charitable Trusts sent a letter Sept. 6 to U.S. Senate leaders Mitch McConnell (R-KY) and Chuck Schumer (D-NY) encouraging the Senate to pass the Opioid Crisis Response Act of 2018, which could improve access to high-quality substance use disorder treatment. Pew is asking the Senate to prioritize proposals that would increase the availability of comprehensive and evidence-based treatment for opioid use disorder, enhance care for vulnerable populations, and evaluate innovative payment models that support provider engagement and improve the quality of care.
