The cost of hospitalization in Crohn's disease.
OBJECTIVE
The aim of this study was to evaluate the demographics, resource use, and costs associated with hospitalization of Crohn's disease patients.


METHODS
All patients hospitalized at our institution from 7/1/96 to 6/30/97 with a primary diagnosis of "Crohn's Disease" were analyzed using a computerized database. Data are presented "per hospitalization."


RESULTS
A total of 175 hospitalizations (147 patients) were identified. Mean patient age was 36.5 yr; 61% were female; 82% Caucasian. Payer mix was most commonly contracted (57%), commercial (21%), or Medicare (13%). 57% of hospitalizations had a primary surgical procedure; the remainder were medical. Average length of stay was 8.7 days (surgical, 9.6 days; medical, 7.5 days). The average cost of hospitalization, excluding physician fees, was $12,528 (surgical, $14,409; medical, $10,020), whereas average charges were $35,378 (surgical, $46,354; medical, $20,744), including physician fees, which averaged $7,249 (surgical, $11,217; medical, $1,959). Mean reimbursements were $21,968 (surgical, $28,946; medical, $12,666) with average weighted reimbursement rates of 60.17% of hospital charges, 69.57% of physician fees. The distribution of costs across subcategories was: Surgery (39.6%), Pharmacy (18.6%), Laboratory (3.8%), Radiology (2.1%), Pathology (0.8%), Endoscopy (0.3%), and Other Hospital Costs (34.9%). Of the hospitalizations, 87% included treatment with steroids, 23% with immunomodulators, and 14% with aminosalicylates; 27% included the administration of total parenteral nutrition, which accounted for 63% of the total pharmacy costs.


CONCLUSIONS
Surgery accounts for the majority of hospitalizations, nearly 40% of their total costs, and 75% of overall charges and reimbursements. Therapy that decreases the number of surgical hospitalizations should substantially reduce inpatient Crohn's disease costs, as well as overall costs.
