HES and NICOR Data Linkage for Cardiac Failure Population Analysis

King's College London80,000 enrolled

Overview

This study is a population-based, patient-level analysis of heart failure in England over a 5-year period using a dataset created by linking HES and NICOR databases. Our analyses will look into the re-occurrence of hospitalisation after the initial diagnosis of heart failure, the influence of population factors on risk of re-hospitalisation, and the resultant cost implications in an NHS environment.

Data from the National Heart Failure Audit (NICOR) and Hospital Episodes Statistics (NHS Digital) will be linked, by NHS Digital, using fields that are recorded in both databases (for example, NHS number). We will receive de-anonymised data that has been pseudo-anonymised, allowing for patient-level analyses but without identifying individual patients.
