The flu isn’t “just flu.” New Ontario research links flu activity to higher risk of invasive pneumococcal disease, and shows RSV’s link appears strongest when flu is also circulating. Another reminder why prevention and vaccination is important. vist.ly/4r8ri

New ODPRN study finds Ontario’s biosimilar policy achieved high biosimilar uptake and substantial cost savings, with most savings attributed to non-insulin biosimilars.

Domperidone Shows No Mental Health Risks Postpartum Postpartum use of domperidone to increase milk production in breastfeeding is not correlated with increased mental health-related emergency department visits.

ODPRN's recent study on domperidone use and postpartum mental health was highlighted in MedBrief.

New #ICESOntario data show progress, but gaps remain in vaccine coverage for newcomer children in Ontario. Linking immunization and immigration data helps identify under-immunized groups and close immunity gaps.

Every child deserves equal protection.

Recent study shows that 60% of patients who began take-home methadone during the first month of COVID-19 returned to daily supervised dosing within six months, highlighting the need to better understand how prescriber and clinic factors influence take-home decisions.

#NAAW

This alignment suggests that public health efforts are concentrated in regions experiencing elevated rates of opioid-related harms.

Given the widespread nature of harms, ongoing efforts are needed to clearly understand specific community-based needs for harm reduction services and supplies.

A recent ODPRN study analyzing provincial harm reduction supply distribution revealed that public health units with the highest rates of opioid-related mortality also had among the highest distribution levels of harm reduction supplies.

The EMS opioid response dashboard has been updated on the Ontario Opioid Indicator Tool with new Q2 2025 data.

Overall, the rate of suspected opioid toxicities treated by EMS in Ontario increased in Q2 2025 compared to Q1, although trends differed across regions.

This evidence reinforces that hospitals and community care need strong, seamless pathways so that people can be connected to OAT quickly and continue receiving support where they live.

During #NAAW, we’re highlighting the importance of creating integrated pathways that reduce preventable harms.

New research highlights: Starting OAT after a hospital-treated opioid toxicity significantly lowers the risk of a repeat overdose.
