Scoring system used to assess risk of kidney disease, and prevalence of each variable in the included cohort

Variable Points attributed Prevalence in included cohort (n, %)
History of kidney disease 1 6 (0.9)
Presence of oliguria (patient reported) 4 217 (33.1)
Infection with fever (≥38°C or ≤6°C) 1 348 (53.1)
Hypotension (<90/60) or shock (presence of hypotension with signs of decreased organ perfusion, such as altered metal status, oliguria or heart failure) 2 82 (12.5)
Pregnancy with hypertension (>140/90 and receiving treatment) or seizures 2 7 (1.1)
Swelling (entire body) 2 25 (3.8)
Decreased appetite 1 463 (70.7)
HIV 1 333 (50.8)
Coma or confusion 2 36 (5.5)
Anaemia (haemoglobin <90 g/L) or pallor 1 121 (18.5)

Score 0–2: low risk; 3–6=moderate risk; >6=high risk. Moderate and high risk were deemed at increased risk of kidney disease and enrolled. Maximum points=17.
