I have the master patient index (MPI) list of AKI-episodes by patients and Laboratory, with a start-date end-date and peak-stage (peak within 30days form AKI-episode start).

Just to clarify how we define an episode:

Consecutive alerts from one person are considered part of the same AKI-episode if there are less that 30days between consecutive alerts.

For example:

Alerts on 1^stFeb, 5^thFeb 19^thFeb 25^thApril 1^stMay and then nothing else will be reduced to

2 episodes: 1-19Feb (start-end) & 25April-1stMay (start-end)

For the pilot:

I’ll select people with AKI-episodes with start/end date between Jan-Feb 2018 from Addenbrooke’s and Leicester laboratories.

Of those people, I’ll keep those that had an hospitalisation during the duration of AKI-episode (this will mean I keep both hospital acquired AKI and community-acquired AKI which result in hospitalisation), if admission date in the first week 2 weeks of February

Then I’ll check the aki-stage of all alerts that were issued during the first 1-2 weeks of the hospital-admission, and keep if AKI-2 or AKI-3 present

So, for example, a person that has an AKI-2 in the community, then goes into hospital after a couple of days but gets only alerts stage-1 during his hospital admission (based on what we hold in the MPI), will not be included in the list of patients

The dataset the UKRR will provide should have:

Date of start and end of AKI episode
Admission and discharge date for the hospitalisation associated to the AKI episode
Hospital of admission (procode-3)
Date and stage of peak AKI during the hospital-stay
ID of patient (name, surname, nhsno, date of birth)
