Patients with kidney dysfunction or serum potassium abnormalities were excluded. We evaluated the association of the potassium concentration in the total infused solutions in the first 2 days of hospitalization with 28-day in-hospital mortality using multivariable regression analysis with a cubic spline model.

The quartile cut-points for potassium concentration were 7.7, 11.4, and 16.1 mmol\/L. Within the range of approximately 10 to 40 mmol\/L, potassium concentration was not associated with occurrence of hyperkalemia or death. Lower potassium concentrations were associated with higher 28-day in-hospital mortality; the odds ratio for patients receiving 8 mmol\/L was 1.69 (95% CI, 1.03 to 2.78; reference: 20 mmol\/L), and the
