1 AKI in Acute Dialysis Units outside ICU across Finland Mikko Haapio, MD Consulting Nephrologist Helsinki University Central Hospital Department of Nephrology

2 FINNAKI-Nephro In conjunction with the main FINNAKI Study First Finnish study to explore acute RRT outside ICUs aims: - Incidence - Characteristics of patients and therapy - Prognosis relating to - RRT modalities - Duration of RRT - Diagnoses - AKI biomarkers

3 FINNAKI-Nephro Inclusion Patients treated in nephrological units, outside ICUs - Acute renal replacement therapy started, or - Indication for acute RRT existed, but a conservative approach was chosen (e.g. high age, multiple comorbidity, etc.)

4 FINNAKI in Nephrological Units (outside ICUs) - 17 (14) centres - 11 with patient recruitment Patient recruitment

5 Centres with patient recruitment patient-% of all Helsinki University Hospital Tampere University Hospital Oulu University Hospital Jyväskylä Central Hospital Kuopio University Hospital Turku University Hospital Pori Cental Hospital Lappeenranta Central Hospital Joensuu Central Hospital Kokkola Central Hospital Vaasa Central Hospital

6 AKI Non-AKI Number of patients Helsinki University Hospital Oulu University Hospital Jyväskylä Central Hospital Tampere University Hospital Kuopio University Hospital Turku University Hospital Pori Cental Hospital Lappeenranta Central Hospital Joensuu Central Hospital Kokkola Central Hospital Vaasa Central Hospital

7 Basic characteristics All patients (n=137) Patients with AKI (n=93) Gender, males n (%) 77 (56) 52 (56) Age, males, median (IQR) 66 (49-77) 64 (49-74) Age, females, median (IQR) 66 (55-77) 68 (59-77) Plasma crea within recent year, median (IQR), µmol/l Plasma crea within recent year, mean (SEM), µmol/l 130 (88-215) 129 (89-205) 181 (14.7) 180 (17.3) Chronic kidney disease, n (%) 75 (55) 56 (60)

8 RIFLE Urine, % of AKI patients All AKI patients AKI patients on RRT 0 Risk Injury Failure

9 Comorbidities, % of AKI patients Hypertension Heart failure Atherosclerotic disease Type 2 diabetes Type 1 diabetes Connective tissue disease Kidney transplant Non-metastatic cancer COPD Chronic liver disease Transplant other than kidney

10 Infection suspected Infection diagnosed Predisposing factors, Hypovolemia % of AKI patients Rhabdomyolysis Hypotension Operation within 1wk Infection in 71%! IV contrast media Cardiogenic shock Resuscitation Acute liver failure Renal artery obstruction Urine flow obstruction Intoxication Massive blood transfusion

11 Predisposing drugs, % of AKI patients Diuretic ACEi or ARB NSAID Nephrotoxic antibiotic Colloid

12 RRT decision, all patients (n=137)

13 First RRT modality, all patients treated (n=107)

14 RRT decisions, patients with AKI (n=93)

15 First RRT modality, AKI patients treated (n=71)

16 Alive at hospital discharge or day 28 all patients (data for 129 of 137) All Males Females n %

17 Alive at hospital discharge or day 28 all AKI patients (n=93) All Males Females n %

18 Alive at hospital discharge or day 28 AKI patients with RRT (n=71) All Males Females n %

19 Alive on day 90 all patients (data for 129 of 137) All Males Females n %

20 Alive on day 90 all AKI patients (n=93) All Males Females n %

21 Alive on day 90 AKI patients with RRT (n=71) All Males Females n %

22 Dialysis dependence and outcome AKI patients with RRT (n=71)

23 Conclusions Acute renal replacement therapy unevenly given across Finland - Local resources and hospital procedures Of acute patients in Finnish Nephrological Units: - About two thirds have AKI % of AKI patients do not enter RRT - Mortality of AKI patients on RRT: - hospital 14% - 90-day 25%

27 Patients with acute congestive heart failure (sub)acutely progressing to dialysis-dependent renal failure survival from RRT start: 95 days (median) to 444 days (mean) Patients > 60 years with acute renal failure RRT for 40%, 26% outside ICUs, 3-year follow-up crea > 124/115 males/females mortality 59% (hospital-acquired ARF) Lindner G ym.

28 n No renal replacement therapy Elderly - AKI 66 ± 12 yrs After hospital discharge: - All: 17,4% died - AKI: 29,8% AKI - Non-AKI: 16,1% Adjusted mortality risk increased according to worsening AKIN stage Lafrance JP, Miller DR, JASN 2010.
