Impact of kidney disease on pediatric SLE hospitalizations^*

		SLE + KI
	SLE – KI	AKF	ESKD	Kidney transplant	No kidney failure
No. of discharges	3,197	433	1,180	111	2,469
Total charges, million $	89.3	42.5	67.2	7.0	60.9
Length of stay, mean ± SEM days	5.5 ± 0.3	13.8 ± 1.2	9.5 ± 0.8	6.8 ± 0.6	4.7 ± 0.3
No. of dialysis events	0	83	701	34	0
Charge/discharge, mean ± SEM thousand $	28.5 ± 1.6	100.0 ± 9.8†	58.2 ± 4.3†	63.7 ± 8.1†	25.0 ± 1.6

^*SLE = systemic lupus erythematosus; SLE – KI = SLE without kidney involvement; SLE + KI = SLE with kidney involvement; AKF = acute kidney failure; ESKD = end-stage kidney disease.

^†P< 0.0001 for comparison of mean charge/discharge for each SLE + KI subgroup with SLE – KI.
