This database contains information on patients with an estimated glomerular filtration rate (GFR) a$?75 ml/min per 1.73 m.sup.2 as calculated by the Schwartz formula, who were treated on or after 1 January 1994. Thus this report reflects 2 years of data entry. Analysis of the data revealed that nearly two-thirds of patients registered had a structural anomaly. On average, patients were 1.5 standard deviations below age- and sex-specific norms for height, and 0.6 standard deviations below weight norms. Mean serum creatinine for the entire group was 2.4 mg/dl and 68% of patients had a baseline GFR of at least 25 ml/min per 1.73 m.sup.2. The mean hematocrit for all children at registration was 33.3+-6.3%, and did not vary among age groups. Overall, 30.9% of patients had a hematocrit &lt 30%. Only 12.8% of patients were receving Epoetin therapy. Although still in infancy, the Chronic Renal Insufficiency Arm of the NAPRTCS database in providing important insights into this disorder.
