Objective. Over the last 2 decades, for-profit dialysis units have become t
he most common providers of renal replacement therapy for adults with end s
tage renal disease (ESRD) and have had an increasing role in the dialysis o
f children. We undertook a study to determine whether dialysis facility pro
fit status influences the choice of dialysis therapy in the pediatric popul
ation.
Design. Cross-sectional study of national data from the Health Care Financi
ng Administration.
Setting. Free-standing and hospital-based outpatient dialysis facilities in
the United States.
Patients. A total of 1568 children and adolescents (less than or equal to 1
9 years of age) eligible for US Medicare ESRD benefits in 1994.
Outcome Measures. The association between dialysis modality choice and the
profit status of the facility. Crude associations were estimated by the OR
of a patient being treated with peritoneal dialysis (PD) versus hemodialysi
s at nonprofit versus for-profit facilities. Adjusted associations were est
imated using logistic regression analysis.
Results. In bivariate analysis, children with ESRD dialyzed at nonprofit fa
cilities were nearly three times as likely as those at for-profit facilitie
s to be on PD (OR: 2.9; 95% CI: 2.3,3.6). In multivariate analysis, after c
ontrolling for patient age, sex, race, cause and duration of ESRD, free-sta
nding versus hospital-based facility, and the pediatric expertise of the fa
cility, patients at nonprofit facilities were more than twice as likely as
those dialyzed at for-profit facilities to be on PD (OR: 2.3; 95% CI: 1.6,3
.4). After taking into account the clustering of patients within facilities
, the association between nonprofit status and the use of PD persisted (OR:
2.2; 95% CI: 1.5,3.2).
Conclusions. Children with ESRD treated at nonprofit facilities are more li
kely to receive PD than are those treated at for-profit facilities even aft
er controlling for other patient and facility characteristics. This finding
suggests that clinical decision making for pediatrics may be influenced by
the ownership of the health care facility in which the patient is treated.
