Quality and Outcomes Framework Indicators: Stroke/transient ischemic attack prevalence (QOF_4_10)
Place-based Longitudinal Data Resource
Summary
This indicator measures the percentage of registered patients recorded in QOF as having stroke. Annual LSOA-level estimates are provided for 2005-2024 in England.
Technical description
QOF achievement records with areaid_id values STIA001, STROKE 1 were used to identify GP practice-year prevalence estimates for stroke. Practice-year records with non-positive denominators or computed prevalences above 30% were excluded. GP practice prevalences were linked to annual patient counts by GP practice, LSOA and year, and weighted averages were calculated using the number of registered patients as weights.
