The potential impact of neighboring states' bans on abortion volume in a haven state.

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.
