Prognosis and serum creatinine levels in acute renal failure at the time of nephrology consultation: an observational cohort study

Table 2 Odds Ratios (ORs) and (95% confidence intervals) for in-hospital mortality; according to the increased percentage of creatinine with respect to basal creatinine*

	GROUPS OF % CREATININE INCREASE
	< 101% increment	≥ 101% increment	p value

n	323	323
Incidence of in-hospital mortality, n (%)	73 (22.6)	115 (35.6)
Odds Ratios
Crude OR (95% CI)	1.00 (Ref.)	1.89 (1.34–2.68)	< 0,001
Age- and sex-adjusted OR (95% CI)	1.00 (Ref.)	1.91 (1.35–2.70)	< 0,001
Multivariate-adjusted OR^† (95% CI)	1.00 (Ref.)	1.81 (1.08–3.03)	0.024
Additionally adjusted for Oncology patients	1.00 (Ref.)	1.85 (1.09–3.14)	0.023

* Creatinine change (%) = [(creatinine at nephrology consultation - Basal creatinine)/Basal creatinine] × 100
^†Adjusted for age, sex, Liano scoring, Karnofsky scoring, prior food intake, chronic renal failure, diabetes, treatment of acute renal failure, causes of acute renal failure, community-acquired acute renal failure, basal hemoglobin, basal serum albumin, and RIFLE classes.
