This section sets out how this indicator is constructed.
This indicator measures the counts and crude rates per 100,000 discharges of different primary diagnoses reported in the emergency admission episode following a discharge that involved a specified diagnosis or procedure. Figures are reported at a national level.
The indicator is presented for the same breakdowns as the associated emergency readmissions indicators:
- For emergency readmissions within 30 days of discharge from hospital by diagnosis (I02041) the diagnosis at the original discharge is matched to the diagnosis at emergency readmission. Diagnoses at discharge are presented separately for fractured proximal femur and stroke.
- For emergency readmissions within 30 days of discharge from hospital by procedure (I02042) the primary operation before the original discharge is matched to the diagnosis at emergency readmission. Operation prior to discharge are presented separately for either hip replacement surgery or hysterectomy.
Fields and Filters
Please refer to the related indicator specifications for filters on the source dataset as this indicator uses the dataset created in the production of the associated emergency readmissions indicator.
Numerator (count of each event)
The following fields and values are used for the numerator:
The original discharge spell where the reference diagnosis or procedure took place:
DISDATE (date of discharge)
The date of discharge of the original attendance in hospital where the primary diagnosis or procedure occurred is within the financial year being reported, 1st April to 31st March inclusive. Note: the three-year pooled results are not used.
PROCODET (Hospital Provider Code)
Valid value. Used to aggregate counts to national level.
SEX (sex of patient)
Equals 1 (male) or 2 (female). Note: values are used to filter into the reporting groups: male only, female only and persons (male and female).
The emergency readmission spell has:
DIAG_4_01 (primary diagnosis)
Is a valid ICD-10 code.
If the code is invalid or there is no emergency readmission then the count is categorised as “Total Discharges, with no emergency readmission”.
The total numerator values (as calculated above) are summed for each breakdown of reporting (or discharge) year, original diagnosis or procedure and sex group.
