SAIL Databank (Wales)

[&quot;Public Health Wales NHS Trust&quot;]

Encrypted Anonymised Linking Field (ALF). This field is derived from by double encryption after splitting demographic information and clinical information; the first encryption occurs in NHS Wales Informatics Service (NWIS), and the second in SAIL. If the NHS number is not supplied in the data extract, then matching methods are applied; please refer to ALF_MTCH_PCT.

ALF_E

Encrypted Unique Cervical Screening Wales ID reference number, joined with Encrypted Anonymised Linking Field (ALF), to give demographic information for Cervical Screening individuals and tests/results by anonymised individual, as well as geographic data down to the LSOA level.

CSW_ALF

Anonymised Linked Field Match Percentage. This number is a match % score from probabalistic matching, when joining together anonymised data. This linkage process consists of matching against the Welsh Demographic Service by NHS number, where a valid number exists, and where there is no valid number then matching is attempted using first name, surname, date of birth, and postcode. This is an artificial score with no real-world meaning; i.e. a match of .99 does not mean there is a 99% chance the match is correct. This number is assigned when deriving the Encrypted Anonymised Linking Field.

ALF_MTCH_PCT

Anonymised Linked Field Status Code. This is assigned when deriving the Encrypted Anonymised Linking Field.

ALF_STS_CD

Date when the data made available i.e. date of loading into database.
