Hypophosphataemia is a common treatable problem in ICU, and is indicative of many pathophysiological processes that occur in critical illness. This audit's objective was to quantify the incidence, severity and timing of hypophosphataemia in the ICU. Namely, the incidence of hypophosphataemia on ICU admission and the incidence that develops following admission.
A retrospective audit of data entered into the computerised medical record database (CareVue) from all admissions between 27 April 2006 and 7 July 2008. The time, date and value of all serum phosphate concentrations were analysed. Abnormal phosphate concentrations were categorised as following: critically low (< 0.3 mmol/l), low (< 0.7 mmol/l), high (>1.5 mmol/l).
Phosphate concentrations in ICU admissions (n = 689)
Hypophosphataemia is common in ICU admissions. Most commonly it develops subsequent to admission to the ICU and reaches critical concentrations in 5% of ICU admissions. The timing of this fall in phosphate may indicate specific pathophysiological processes and merits further investigation.
