Corrigendum to "The Impact of Payment Reform on Pediatric Craniofacial Fracture Care in Maryland"

Our study, “The Impact of Payment Reform on Pediatric Craniofacial Fracture Care in Maryland,” published in 2021 (Vol. 14(4), pages 308–316, https://doi.org/10.1177/1943387520983634) in the journal Craniomaxillofacial Trauma & Re- construction, is an analysis of the HCUP Kid Inpatient Database (KID), a restricted-access, publicly available dataset that is maintained by the Agency for Healthcare Research and Quality (AHRQ).

One of the provisions of the Data Use Agreement (DUA) is that no data observation involving less than or equal to 10 observations is to be published. It has come to our attention that the original version of our manuscript contained tabulated cells that contravene the above provision. To remedy this, we hereby provide an amended
