  1. Quality of life is measured with the EuroQol (EQ-5D) index and with the visual analogue scale (VAS) score. AKI; Acute kidney injury, IQR; interquartile range (25th to 75th percentiles), RIFLE, Risk, Injury, Failure -classification; SAPS, Simplified Acute Physiology Score; SMR, standardised mortality ratio. Treatment restrictions include: 1) no resuscitation, 2) no increase in the intensity of treatment, 3) treatment withdrawal.
