Purpose: The aims of this study were to describe health care costs and char
ges for patients with sickle cell disease (SCD) and identify predictors of
high use.
Patients and Methods: Patients with SCD were identified by International Cl
assification of Diseases, 9th revision, Clinical Modification (ICD-9-CM) co
des from a university hospital's administrative databases from January 1, 1
996, to September 30, 1997. Clinical and administrative data were gathered
on each patient for all hospital admissions and ambulatory clinic visits. L
ogistic regression models were used to determine predictors of high health
care use.
Results: A total of 947 patients with SCD were identified, 73% of whom resi
ded within three South Carolina counties. On average, there were 0.9 admiss
ions per patient per year and 8.0 outpatient visits per patient per year. M
ean inpatient hospital charges, physician charges, and direct hospital cost
s per admission were $7290, $1589, and $5405, respectively, and the average
length of stay was 4.5 days. Mean hospital charges, physician charges, and
direct hospital costs per outpatient visit were $305, $169, and $688, resp
ectively. Forty percent of the inpatient hospital charges were accounted fo
r by only 4.2% of the patients. Residing in a distant county and being admi
tted with a diagnosis of painful respiration were found to be predictors of
excessive charges and expenses beyond expected reimbursements.
Conclusions: Patients with SCD are frequent users of health care services.
Charges and costs are distributed disproportionately across these patients.
Predictors of excessive hospital charges include living geographically dis
tant from the hospital and being admitted with a diagnosis of painful respi
ration.
