Version 3 introduced a mechanism whereby General Practice and NHS Trusts can “add” patients and Version 4 allowed General Practice to “subtract” individuals from the SPL. This is independent of disease coded data picked up by the algorithm and, for example, supports professional and clinical judgement by a GP or by a speciality consultant in a NHS Trust.
The mechanism for the additions and subtractions for hospitals, is by marking an individual record as either addition or subtraction in the appropriate field of the SPL Trust data collection template submitted via the Strategic Data Collection Service (SDCS) solution.
Additions and subtractions to the SPL from General Practice is managed through the use of the appropriate SNOMED CT Code as entered into the patients record, as follows:
|1300591000000101||Low risk category for developing complication from COVID-19 infection (finding)|
|1300571000000100||Moderate risk category for developing complication from COVID-19 infection (finding)|
|1300561000000107||High risk category for developing complication from COVID-19 infection (finding)|
The most recent code (determined by date of event where risk code is applied) will be used to determine a patient’s entry to, or removal from, the SPL.
Therefore, the methodology now follows the process below:
- Data sources: GP clinical, hospital commissioning, primary care (dispensed medicines), maternity
- Baseline SPL (algorithm only)
- Additions and subtractions
- Composite SPL
