Aims Electroconvulsive Therapy (ECT) is a well-established and effective treatment in mood disorders but the use of ECT in Texas is much lower than the general average among the United States. Our goal is to explore the geographical accessibility of Electroconvulsive Services in Texas. Methods 22 ECT Centers in Texas listed in State's 2016 annual ECT report were enrolled and georeferenced. We used Esri's StreetMap Premium Network release 1 network dataset to generate 1-hour drive time service areas for these ECTs. We estimated populations within these service areas based on US Census Tract level population-weighted centroids; generated from the 2015, American Community Survey (ACS) estimates at the US Census Block Group level. Results About 75% (19,851,802 of 26,538,614) of Texas total population is within a 1-hour drive time to any ECT Services location. When focusing on population below the poverty level from 2015 Block Group level ACS data: 68% (3,046,141 of 4,472,451) are within a 1-hour drive time. Conclusions ECT services are geographically accessible in Texas. Other barriers may contribute to lower use of ECT.
