To determine the extent to which opioid prescribing rates vary across US congressional districts.Methods
In an observational cross-sectional framework using secondary data, we constructed 2016 congressional district-level opioid prescribing rate estimates using a population-weighted methodology.Results
High prescribing rate districts were concentrated in the South, Appalachia, and the rural West. Low-rate districts were concentrated in urban centers.Conclusions
In the midst of an opioid overdose crisis, we identified congressional districts of particular concern for opioid prescription saturation.Public Health Implications
The congressional district geography represents a policy-relevant boundary and a politically important level at which to monitor the crisis and determine program funding. Furthermore, in the context of the opioid crisis, knowing how congressional districts rank across the country and in states is useful in the creation of policies targeted to areas in need.
