Behavioural patterns of electrolyte replacement. Majority of lab values for potassium, magnesium, and phosphate were reported in the morning with replacement orders being placed in the morning (majority) and afternoon (a significant minority) (A). The increased dose of electrolytes resulted only in a modest increase in post-repletion values (B). Small yet significant number of providers repleted electrolyte above the reference levels (C). The replacement timelines revealed significant overlap between placement of the order for replacement and ordering follow-up lab (D).
