Admission hyperphosphatemia as a predictor of severity and mortality in acute pancreatitis: A 1000-patient cohort study

Table 2 Clinical outcomes according to admission serum phosphate levels

Clinical outcome	Hypophosphatemia (< 2.5 mg/dL, n = 150)	Normophosphatemia (2.5-4.5 mg/dL, n = 750)	Hyperphosphatemia (> 4.5 mg/dL, n = 100)	P value
Severe acute pancreatitis	60 (40)	150 (20)	60 (60)	< 0.001
Pancreatic necrosis	30 (20)	75 (10)	50 (50)	< 0.001
ICU requirement	45 (30)	113 (15)	70 (70)	< 0.001
Length of hospital stay, median (days)	10	7	14	< 0.001
30-day mortality	8 (5)	23 (3)	25 (25)	< 0.001

Outcomes are presented as n (%), except for length of stay, which is shown as median days. ICU: Intensive care unit.
