Health care cost and utilization project analysis of comorbid illness and complications for patients undergoing hysterectomy for endometrial carcinoma.
OBJECTIVE
The objective was to study the association of race, comorbid illness, and lymph node dissection (LND) with complications in patients undergoing hysterectomy for endometrial carcinoma.


METHODS
The Health Care Cost Utilization Project analysis studied women undergoing hysterectomy for endometrial carcinoma in 1996. Chi-square and Student t tests were used to determine differences in means or proportions. Linear, stepwise, and three-stage regression analyses were used to build predictive models for charges and lengths of stay (LOS).


RESULTS
The mean age of the 5730 patients was 64.5 (standard deviation, 12.37); 72% of the patients were white, 5% were African American, and 23% were classified as "other." Ninety percent underwent total abdominal hysterectomy, 5% total vaginal hysterectomy (TVH), 4% radical abdominal hysterectomy, and 1% TVH/laparoscopy. Thirty-eight percent also underwent LND. Lymph node dissection was performed more frequently at teaching hospitals (P = 0.0000) and was associated with more complications. Comorbid illness (i.e., diabetes, heart disease) was documented in 51% of admissions, and > or = 1 comorbidity was documented in 21.5%. African Americans were more likely to have one or more comorbid illnesses, underwent more LNDs (P = 0.02), suffered more complications (P = 0.0001), and were more likely to die in the hospital compared with whites or others (P = 0.000). Although LND, complications, and longer LOS were more likely to occur in teaching hospitals (P = 0.0005), total charges and inpatient death were not higher in teaching hospitals.


CONCLUSIONS
The higher frequency of comorbid illness, complications, LND, and inpatient death in African Americans reflects severity of medical illness and cancer in these patients. Teaching hospital admission was associated with more complications and longer LOS, but not a higher death rate.
