Purpose: To anticipate the clinical challenges and financial risks facing p
hysicians and managed care organizations who care for children with chronic
illnesses, such as sickle cell anemia (SCA), under capitated managed care
arrangements.
Patients and Methods: A cross-sectional study based on claims data from the
Washington State Medicaid Program (WSMP) and the Federal Employees Health
Benefits Program (FEP). Expenditure patterns were compared for children 18
years of age or younger for whom a claim with a diagnosis of SCA was submit
ted and paid in the State of Washington during fiscal year 1993 (FY1993) or
by the FEP during FY1992 to expenditure patterns for all children.
Results: Children with SCA had mean expenditures 8.8 times the mean expendi
tures for all children in WSMP. There was wide variation in the annual expe
nditures among children with SCA; the most expensive 10% of children accoun
ted for 56% of total expenditures. Ninety-seven percent of the expenditures
were concentrated in four broad categories: 72% for inpatient care, 11% fo
r outpatient care, 11% for physician payments, and 3% for prescription drug
s. Examination of expenditure and utilization patterns for children with si
ckle cell anemia enrolled in the FEP yielded similar results.
Conclusions: Unless managed care organizations and capitated pediatricians
receive payment rates that reflect the higher expected expenditures of cari
ng for these children, access to and quality of care may suffer. Analyses o
f practice guidelines and utilization patterns suggest that newborn screeni
ng, regular access to specialty facilities, and comprehensive education pro
grams are critical areas that are vulnerable to reductions under capitation
