Methadone-involved overdose deaths in urban and rural communities before and after the public health emergency flexibilities for methadone take-home doses.

BACKGROUND

To mitigate COVID-19 exposure risks in methadone clinics, the Substance Abuse and Mental Health Services Administration (SAMHSA) issued a temporary modification of regulations in March 2020 to permit extended take-home methadone doses: up to 28 days of take-home methadone for stable patients and 14 days for those less stable. This study examined the association between the policy change and fatal methadone overdoses across the urban-rural continuum.

METHODS

This interrupted time series analysis used the U.S. National Vital Statistics System (NVSS) 2018-2022 mortality data to examine monthly trends in methadone-involved overdose deaths before and after the policy change allowing more take-home methadone doses. Deaths were stratified into six urban-rural categories and by co-involvement of fentanyl.

RESULTS

Prior to the policy change, trends in methadone-involved overdose deaths were either flat or declining across all urbanization categories. Following the policy change, deaths decreased significantly in Large Central Metro areas but increased in rural Micropolitan counties. No trend changes occurred in the other urban or rural categories. When stratified by fentanyl co-involvement, Large Central Metro areas experienced a decrease in methadone deaths with fentanyl, though not statistically significant, and a significant decrease without fentanyl. In rural Micropolitan counties, methadone deaths saw an increase with fentanyl co-involvement that did not reach significance, and a significant increase without fentanyl. Noncore counties saw a significant increase in deaths involving both methadone and fentanyl, with no notable change observed without fentanyl.

CONCLUSIONS

Results suggest the need to expand methadone access and treatment supports in underserved rural communities, recognizing that factors beyond the policy change may have contributed to the reported associations.
