Objectives: We explored the potential impact of abortion bans in neighboring states on Michigan's abortion volume.
Study design: Using ArcGIS mapping software, we determined which counties in neighboring states had their closest out-of-state abortion clinic in Michigan. We estimated the change in abortions in Michigan occurring from neighboring states' residents, assuming complete bans in those states.
Results: Complete bans in neighboring states could increase abortion volume in Michigan by approximately 5928 out-of-state patients annually (21% increase).
Conclusions: Complete bans in neighboring states may markedly increase abortions occurring in Michigan, which may strain Michigan facilities' capacity to provide abortion care.
