Influenza immunization rate gap (by deprivation band)
Health Equity
How this indicator is defined
Methodology version v1.0
Percentage-point difference in influenza-immunization coverage between patients in the most-advantaged deprivation band (equity stratum 1) and the least-advantaged band (equity stratum 5). A smaller gap reflects more equitable care.
Equity gap (percentage points)
The Influenza immunization rate for the most-advantaged deprivation band (equity stratum 1) minus the rate for the least-advantaged band (stratum 5), in percentage points. A smaller gap reflects more equitable care. The gap is not computable when either band has no eligible patients.

Derived from
What this indicator measures— Name, alignment, goal, rationale.
- Indicator nameField 1 — Indicator name
- Influenza immunization rate gap (by deprivation band)
- AlignmentField 2 — Alignment
- Health-equity measurement: stratified-coverage disparity
- NACI / health-equity reporting
- Illustrative synthetic-demo definition pending clinical review
- Strategic goalField 3 — Strategic goal
- Reduce inequity in influenza-immunization coverage across the rostered population by closing the gap between the most- and least-advantaged patient groups.
- RationaleField 5 — Rationale
- Stratifying an existing quality measure by a deprivation band surfaces inequities that the panel-wide average hides. Closing the gap is a recognised health-equity goal; the band is an opaque 1–5 quintile (no raw demographics), PHI-safe by the same reasoning as year-only DOB.
How it's computed— Scoring method, numerator, denominator, inclusions, exclusions.
- NumeratorField 6 — Numerator
- Most-advantaged band influenza-immunization coverage minus least-advantaged band influenza-immunization coverage (percentage points).
- DenominatorField 7 — Denominator

- Active as of reporting-period end: yes
- ExclusionsField 9 — Exclusions
- Patients with no assigned equity stratum (unstratified).
