New pub @NEJM: after elimination of the waiver requirement to prescribe buprenorphine, the # of prescribers increased, but the # of patients changed little. @UM_IHPI @UMchear @contirena1 @MarkBicket @PoojaLagisetty @thuynguyen_dieu @Amy_Bohnert @NIDAnews

New pub @NEJM: leucovorin Rx to children increased after federal officials suggested it was effective for autism in a national press conference. No large randomized trials have evaluated leucovorin's effectiveness and safety for children with autism.

Results of this study suggest that patients who switch to a HDHP may experience heightened barriers to buprenorphine use.

New pub: 90% of dental opioid Rx in youth are for tooth extraction, even though non-opioids are equally effective. As dentists write 42% of opioid Rx to youth, ~1/3 of youth opioid Rx may be for tooth extraction. @drchadb @UM_IHPI @UMchear

US dental opioid rx ⬇️27.1% from '21–'24 but was 24× the country with the lowest rate. This comparison suggests there are opportunities to reduce opioid rx by US dentists.

New pub @JAMANetworkOpen: opioid prescribing by U.S. dentists is declining but remains high by international standards. In 2024, the U.S. dental opioid dispensing rate was 24x higher than the Netherlands.

North Carolina’s Medicaid expansion under the Affordable Care Act slowed the decline in buprenorphine dispensing that occurred during Medicaid unwinding.

For Medicare surgical patients, mandates to check the prescription drug monitoring program database did not reduce opioid prescribing or adverse events.

This analysis of a nationally representative survey of child health revealed that food insecurity is more common in children with any of 7 chronic conditions compared with children without these chronic conditions. ja.ma/4nQxb7o
ALT Line graph showing prevalence (%) vs survey year(2019-2023) for 'No chronic condition' and 'Any chronic condition'. 'No chronic condition' starts at 10%, dips to 6% in 2021, then rises to 11% in 2023. 'Any chronic condition' starts at 16%, dips to 9% in 2021, then rises to 16% in 2023.

From 2019–2023, U.S. children with chronic conditions were consistently more likely to experience food insecurity than peers without such conditions.

Routine childhood & teen immunizations are ⬇️ in MI, with slower HPV vax gains—especially in lower-income, high-uninsurance counties. Targeted efforts may be needed.

New pub @AAPJournals: child/teen vaccination declined from 2017-2023 in Michigan; HPV vax increased less than expected. Declines were more pronounced in low-income and high-uninsurance counties. Progress towards increasing immunizations is stalling. @UMchear @UM_IHPI @MottDocs

A $10 increase in buprenorphine cost-sharing was estimated to have no effect on prescription abandonment for commercially insured patients and a slight increase for #Medicare-insured patients. ja.ma/3ItG4Es @contirena1 @poojalagisetty @kaopingchua
Kao-Ping Chua retweeted
New pub @JAMAHealthForum: we estimated the association between cost-sharing and buprenorphine dispensing by exploiting the abrupt increase in cost-sharing at the beginning of the calendar year, when deductibles reset in private and Medicare plans @kaopingchua @contirena1

New @AAPJournals: using national data, we show that the Adderall shortage caused some children using this drug to switch to other stimulants. Other children stopped using stimulants altogether, especially Medicaid patients. @UM_IHPI @UMchear @contirena1
