What is your approach to electrolyte repletion for patients hospitalized with cardiac and non-cardiac conditions?

My approach to electrolyte monitoring and repletion emphasizes a patient-specific risk assessment rather than adherence to arbitrary numeric thresholds. The routine, reflexive repletion of potassium, magnesium, and phosphorus in unselected medical inpatients is an overused practice with limited supp...

Other than cardiac, the other conditions I pay att...
