  1. The influence of multiple patient and hospital factors on the likelihood of any imaging exam being ordered during United States Emergency Department encounters is shown with adjusted odds ratios from the logistic regression model. Model variables include patient race/ethnicity, age, gender, insurance payor, number of co-morbid conditions, hospital region and setting, and survey year
  2. a Data only available from 2012 to 2016
  3. b Urban hospitals are designated as in a Metropolitan Statistical Area (MSA) by the NHAMCS survey
