Hippo’s HPV indicator identifies and recalls patients aged 18–24 years who are eligible for HPV vaccination but have not yet received it.
It aligns with NHS vaccination guidance and supports proactive recall for both females and eligible males born on or after 1 September 2006.
📋 The Eligible Population
Cohort | Eligibility | Definition |
HPV_18TO24_CATCHUP | Patients aged 18–24 years during the service year | - Females: All aged 18–24 |
✅ In short: this indicator includes all females aged 18–24 and eligible males born after 1 September 2006.
🩺 The Indicator
🎯 HPV_18TO24_CATCHUP — HPV Catch-up Vaccination
Measures:
% of patients aged 18–24 years who received at least one HPV vaccination before their 25th birthday.
Counts as complete if:
HPV vaccination (or “HPV given by other provider”) recorded, and
Vaccination date is before the 25th birthday.
Exclusions:
HPV vaccine declined (coded decline).
HPV vaccine contraindicated (coded contraindication).
⚙️ Hippo Eligible Rule
Trigger | Description |
Eligibility date: | Patients become eligible on their 18th birthday and remain eligible until the day before their 25th birthday. |
✅ In short: recall begins when a patient turns 18 and continues until they reach 25.
⚠️ Common Pitfalls
Vaccine recorded after 25th birthday (excluded).
Decline or contraindication entered in free text instead of coded.
Males born before 1 September 2006 incorrectly included.
Missing “HPV given by other provider” codes for school/community vaccinations.
🧩 Putting It All Together
Indicator | Focus | Who It Applies To | What It Measures | What to Do |
HPV_18TO24_CATCHUP | HPV vaccination (catch-up) | Females 18–24; males 18–24 born ≥1 Sept 2006 | % vaccinated before 25th birthday | Record HPV vaccination (or valid decline/contraindication) |
🌟 Why This Matters
Following this indicator helps practices:
Identify patients who missed HPV vaccination in school programmes.
Ensure equitable HPV protection across genders.
Support national HPV vaccination targets and proactive recall.
✅ In short: HPV_18TO24_CATCHUP helps you ensure every eligible 18–24-year-old is protected — or appropriately coded — before turning 25.
