Under 75 mortality rate from all cardiovascular diseases - ICP Outcomes Framework - Resident Locality

This dataset presents the under-75 mortality rate from all cardiovascular diseases in England. It captures the rate of deaths attributed to circulatory diseases (ICD-10 codes I00–I99) among individuals aged under 75, using directly age-standardised rates per 100,000 population. The data is aggregated into quinary age bands and is available for both single years and three-year rolling averages, providing a comprehensive view of premature cardiovascular mortality trends.

Rationale

Cardiovascular diseases remain a leading cause of premature mortality in England. Monitoring under-75 mortality rates helps identify health inequalities, assess the effectiveness of public health interventions, and guide resource allocation. This indicator supports efforts to reduce preventable deaths and improve cardiovascular health outcomes.

Numerator

The numerator is the number of deaths from all circulatory diseases (ICD-10 codes I00 to I99) registered in the respective calendar years, among individuals aged under 75. These figures are aggregated into quinary age bands (e.g., 0–4, 5–9, ..., 70–74) and sourced from the national Death Register.

Denominator

The denominator is the population of individuals aged under 75, also aggregated into quinary age bands. For single-year rates, the population estimate for that year is used. For three-year rolling averages, the denominator is the sum of the populations over the three years. Population data is sourced from the 2021 Census.

Caveats

Data may not align exactly with published Office for National Statistics (ONS) figures due to differences in postcode lookup versions and the application of comparability ratios in the Office for Health Improvement and Disparities (OHID) data. Users should consider these factors when comparing with other sources.

Localities Explained

This dataset contains data based on either the resident locality or registered locality of the patient, a distinction is made between resident locality and registered locality populations:

• Resident Locality refers to individuals who live within the defined geographic boundaries of the locality. These boundaries are aligned with official administrative areas such as wards and Lower Layer Super Output Areas (LSOAs).
• Registered Locality refers to individuals who are registered with GP practices that are assigned to a locality based on the Primary Care Network (PCN) they belong to. These assignments are approximate—PCNs are mapped to a locality based on the location of most of their GP surgeries. As a result, locality-registered patients may live outside the locality, sometimes even in different towns or cities.

This distinction is important because some health indicators are only available at GP practice level, without information on where patients actually reside. In such cases, data is attributed to the locality based on GP registration, not residential address.
