Use of Inpatient Imaging Services by Persons Without Health Insurance

Distribution of procedures across modalities. Four procedure code variables were used in calculations. Modality bars are arranged from the bottom up in ascending order of mean relative value units. Results were weighted to be representative of the entire inpatient population that received imaging services.

Odds ratio of being uninsured for persons using a given modality. Height of bar represents the odds that a person using a particular modality is uninsured rather than insured. Odds ratios were computed from logistic regression. Modalities are sorted in order from lowest to highest mean relative value units.
