Clinical risk factors associated with 30-day hospital readmission in survivors of septic shock.

Independent Variable *	Adjusted Odds Ratio (95% CI)	p-value
Oncology	3.02 (1.60 – 5.68)	0.001
Recent hospitalization	2.26 (1.19 – 4.29)	0.01
Length of stay, > 4 days	2.18 (1.02 – 4.64)	0.04
Initial lactate levels (mmol/L)	0.89 (0.78 – 1.01)	0.07
PICC at discharge	1.68 (0.66 – 4.25)	0.27

Definition of abbreviation: CI=confidence interval; PICC=peripherally-inserted central catheter.

^*An adjusted odds ratio of greater than 1 represents an increased risk of 30-day hospital readmission. The potential confounder, year of admission, was neither associated with the dependent variable nor did its inclusion alter the odds ratios of any of the candidate risk factors significantly. Conversely, a recent hospitalization attenuated the association between length of stay and 30-day readmission significantly.
