Hi
I am just working through the test system for Telepath for AKI. Several points so far:

1. Paediatrics- the test seems to have a different definition to what I would interpret from the algorithm. The test below passed the test as defined but the AKI score was 3 for a rise of just over 50%
(note that  a single result of creat 315 (ULN 55)  with no previous did not raise a warning)
Has the algoritm been altered?

"Telepath: Patient 21  (paediatric)	We have made the following assumptions: patient age 17, upper end of reference range for serum creatinine 100µmol/l							
							
AKI AKI Warning Stage 3; 	High creatinine >3x upper limit of reference range with >50% increase from median over days 8-364							
Date	Date and Time	Creatinine (µmol/l)
01/06/2014	10:00:00	315								
30/03/2014	11:00:00	208"

2. A rise in creatinine which proves to be chronic produces an AKI score initally but this stays on subsequent results until the median moves up. On the test patients in the algorithms this seems to last 3 months plus. Not  ideal but may be a necessary evil. Does the group have any handle on what proportion of daily alerts are actually 'hangers on'?
