Association between blood phosphorus level and clinical outcomes in critically ill patients: A systematic review and meta-analysis.

Clinical takeawayIn critically ill patients, phosphorus derangements are prognostic markers of illness severity rather than treatment targets, so continue routine monitoring and repletion of symptomatic hypophosphatemia but do not treat the number expecting a mortality benefit.
What it foundHyperphosphatemia was associated with increased ICU mortality (RR: 1.21) and hospital mortality (RR: 2.10), while hypophosphatemia was linked to prolonged ICU stay (+1.53 days) and mechanical ventilation duration (+1.54 days).
ContextConfirms prior concerns about phosphate abnormalities in ICU patients but refines understanding by quantifying associations with specific outcomes. Current practice lacks standardized phosphate monitoring protocols in this setting.
No standard claimed for this paper

Every paper is compared to the standard governing its question. This one is not: either no standard in the corpus matches it, or the comparison did not hold up on review and was withdrawn rather than published unverified. Both are logged.
