Neonatal abstinence syndrome (NAS) is a condition where a baby is exposed to addictive drugs (like opioids) while in the mother’s womb and has become dependent on the drug. The baby can experience withdrawal symptoms shortly after birth.

In 2020 in Simcoe Muskoka, there were 47 infants that were admitted to hospital for NAS for a rate of 9.0 (6.6, 12.0) admissions per 1,000 live hospital births. This was significantly higher than the Ontario NAS rate of 6.0 (5.6, 6.4) admissions per 1,000 live hospital births.

The NAS rates increased significantly in Simcoe Muskoka from 2003 to 2013, but the rates had leveled from 2013 to 2019 before dropping substantially in 2020. It is unclear what the impact of the pandemic was on the local NAS rates. The provincial NAS rates have been steadily increasing over the 18-year time period from 2003 to 2020.
