Receipt of buprenorphine and naltrexone for opioid use disorder by race and ethnicity and insurance type

About The Study: In this cohort study of opioid-related index health care events, race and ethnicity–based and insurance-based disparities in access to medications for opioid use disorder persisted despite efforts to expand treatment availability. These findings underscore the need for targeted interventions, including culturally tailored care, expanded access points, and policy reforms to address structural barriers and reduce inequities contributing to the overdose crisis.

Study challenges climate change's link to our wild winter jet stream

Dartmouth College
Peer-Reviewed Publication

A Dartmouth study uses machine learning to reexamine whether climate change is causing large waves in the polar jet stream that have brought Arctic-like temperatures and storms to temperate regions of the United States in recent years. The researchers constructed a timeline of the jet stream's wintertime variability since 1901 and found it's in the latest of several “wavy” periods from the past 125 years, most of which predate significant effects of climate change. The authors report that climate change is likely not amplifying extreme winter weather by making the jet stream wavier, but through more direct links such as a warmer atmosphere that retains more moisture.

Can targeted payment adjustments help solve the infectious disease physician shortage?

Harvard Pilgrim Health Care Institute
Peer-Reviewed Publication

A new analysis by researchers from the Harvard Pilgrim Health Care Institute examines the first Centers for Medicare and Medicaid Services (CMS) add-on code targeting a single physician specialty: infectious disease (ID). The measure is a significant departure from the agency’s past strategies, with the potential to combat the growing shortage of ID physicians and broader implications for physician reimbursement and healthcare delivery, according to the authors.
