Abbreviations: LOS = length of stay, ICU–intensive care unit, sCA-I = Suspected community acquired infection, CA-AKI = Community acquired acute kidney injury, OR = Odds Ratio, CI = 95% Confidence interval. All AKI stages were grouped together for LOS and ICU admissions. Length of stay data was available for 61,096 of attendances (99.4%). All OR were adjusted for age and sex. Referent group was no sCA-I and no CA-AKI
