Unweighted sample of n=362,785 discharges.
Unweighted sample of n=56,901 discharges.
Variable signficantly interacted with race to predict ECT availability; see Table 3 for white versus black odds ratios of interaction contrasts from the model. Results based on HCUP-NIS weighted sampling of a total of 419,686 discharges of inpatients aged ≥18 with a principal ICD-9-CM diagnosis 296.3x, representing a weighted total of 2,933,646 discharges. ECT availability defined as treatment in a hospital where at least one inpatient received ECT during the calendar year. See text for variable definitions.
