Model-adjusted probability of a delirium event according to major surgical oncology procedures (MSOPs). Predicted probabilities are derived from multivariable logistic regression models that adjusted for patient demographics (i.e., gender, race/ethnicity, Charlson comorbidity index and insurance status), and hospital characteristics (i.e., hospital size, location, length of stay, teaching status, region, and hospital MSOP volume), as well as for patients neurologic disorder (dementia, alcohol induced mental disorder, mood disorder, non-organic disorder, anxiety disorder, alcohol dependence, schizophrenia disorder, drug dependence syndrome, non-dependent drug use, and drug-induced disorder).
