Treatment (Encounter)

UKRR: This is required for V4 & V5 of the UKRR Dataset.

The Treatment entries should be similar to what was sent in the TXT entries in the quarterly files.

Basically they’re meant to represent a period of time that a patient was under the care of a hospital for the purpose of receiving a particular type of care. It is possible for treatment records to overlap if a patient has multiple treatments (such as post-transplant dialysis). A treatment record should exist for any period of time where they would be considered a patient (so for example code 900 record for pre-RRT CKD and a code 94 record for post-RRT Conservative care).

They’re not meant to represent individual out-patient spells with the possible exception of someone having a transplant procedure.

So for example –

• FromTime – 01/01/2000

• ToTime – 01/01/2001

• AdmitReasonCode = 900 (CKD)

• HealthCareFacilityCode = REE01  

• FromTime = 01/01/2001

• ToTime = 01/01/2002

• AdmitReasonCode = 1 (HD)

• HealthCareFacilityCode = REE01

• FromTime = 01/01/2002

• AdmitReasonCode = 29 (TX)

• HealthCareFacilityCode = REE01

AdmitReasonCode is Modality, HealthCareFacilityCode is Treatment Centre. If the patient has Transferred-In from another Renal Unit AdmissionSource should be populated, ideally with the code of the unit or 995/ABROAD if unknown.

Where possible/applicable DischargeReasonCode should be populated with one of these Modalities ( resources/schema/ukrdc/Types/CF_RR7_Discharge.xsd at master · renalreg/resources ) .

Where the code indicates that the patient has “Transferred Out” then DischargeLocationCode should be populated, again ideally with the code of the Unit they are going to or 995/ABROAD if unknown.

A possible idea for the future is that DischargeReasonCode may also be used to record things such as the reason a patient changes from HD to PD etc. that we tried to capture in V4 but that will be something for beyond V5.

PAT33 - First Seen Date

This will be derived in the UKRDC UKRR Extract by looking for a Treatment entry with a Modality of 101 (“First assessment in Kidney Service”). This could be recorded with the other Treatment entries in the Renal System or just be how a “First Seen” date recorded on an RRT record is supplied. a ToTime should be supplied even if it is just the same vaue as the FromTime.

If a 101 modality is not found the value will be taken from the start date of the earliest other Treatment entry.
