Design outcomes

Primary

Measure	Time frame
Difference in incidence of hyperkalemia above 5.5 mmol/l when comparing potassium levels from point-of-care whole blood testing and serum measurements from the LMU Hospital's central laboratory.	—

Secondary

Measure	Time frame
Incidence of hyperkalemia above 6.0 mmol/l when comparing potassium levels from point-of-care whole blood testing and serum measurements from the LMU Clinic's central laboratory. Influence of factors e.g. diabetes mellitus, GFR, metabolic acidosis, and concomitant medication are taken into account in the evaluation.	—
