Abstract
To determine whether gender is associated with the use of ancillary services in hospitalized patients. A retrospective study of laboratory and radiology tests ordered for medical and surgical inpatients over 16-month and 20-month periods, respectively. Obstetric patients were excluded. Number of clinical laboratory and radiology tests per admission, their associated charges, and total charges per admission were measured. In crude analyses, women had 16.5% fewer clinical laboratory tests (p < .0001) with 18.8% lower associated charges (p < .0001) and 24.4% fewer radiology tests (p < .0001) with 15.6% lower associated charges (p < .0001) than men. Total changes for the admission were lower for women in both the clinical laboratory study period ($16,178 vs $18,912, p < .0001) and the radiology study period ($14,621 vs $18,182, p < .0001). When adjusted for age, race, insurance status, service, diagnosis-related-group weight, and length of stay, these differences were smaller but persisted: women had 3.7% fewer laboratory tests performed (p < .001) with 4.8% lower associated charges (p < .001). In similarly adjusted analyses for radiology studies, women received 10.4% fewer radiology examinations (p < .001), with 4.1% lower associated charges (p < .01). There were no significant differences in the adjusted total charges in the laboratory group ($17,450 vs $17,655, p = .20) and only a marginally significant difference in the radiology group ($16,278 vs $16,498, p = .05). When we compared ancillary utilization within the five largest diagnosis-related groups, these differences persisted. Men receive more ancillary services than women, even after adjusting for potential confounders.
