To our knowledge, this is the first report examining national use and utilization rates of on-station VHA chiropractic care by patient sex. This is consistent with prior work assessing the ongoing expansion of VHA chiropractic clinics nationally [12, 13]. We found utilization of VHA chiropractic care was slightly higher for females compared to males. Additionally, VHA’s implementation of chiropractic care has not reached full market penetration, thus at present veterans may be facing barriers to accessing VHA chiropractic care . Future observational database studies and qualitative work assessing stakeholder perceptions may help identify facilitators and barriers to accessing and using VHA chiropractic care.
