Criteria used by reviewers to determine the requirement for dialysis (one or more required)

1.	Evolving hyperkalaemia (K greater than 5.5 mmol/L) and renal impairment.*
2.	Evolving acidosis (pH < 7.35, HCO3 < 15) and renal impairment.*
3.	Fluid overload not manageable by conservative measures and evolving renal impairment. *
4.	Uncontrolled seizures in the setting of renal impairment*
5.	Pericarditis in the setting of renal impairment*
6.	Dialysis initiated appropriately by treating physicians before above criteria were met (eg. significantly worsening renal impairment despite conservative measures)

* Renal impairment: BUN greater than 30 mmol/L or plasma creatinine > 200 μmol/L.
