Investigation into Health Inequalities in Re-admission Rates

Leads: Dr Claire Lawson, Prof Kamlesh Khunti (ARC EM), Dr Katharine Reeves, Dr Hannah Crothers, Ms Sandra Remsing (Meths)

Public Contributors linked to the ARC WM Research Methods theme will work with the project leads to maximise impact of this study.

Dates: February 2020 – ongoing


Admissions for heart failure (HF) constitute a high proportion of all hospital admissions. In addition, patients with heart failure tend to have a high re-admission rate. The biggest risk of mortality is usually associated with the first admission.

Policy and Practice Partners:

None, but see below.

Co-Funding Partners:


Aims and Objectives:

To investigate whether these costly and prevalent outcomes for heart failure patients differ by group factors such as sex, ethnicity and deprivation, and also to characterise trends in these outcomes over a twenty year period. Further, we aim to identify the independent predictors of 30-day readmissions in different HF population groups.


This study analyses data from the inpatient tables of the Hospital Episode Statistics database. All emergency admissions of adult patients with a primary diagnosis of heart failure since 2001 were identified, with the first such admission being taken as the index admission. Information on co-morbidities (such as diabetes, asthma, depression, etc.) and cardiac interventions (such as coronary artery bypass grafting, pacemaker insertion, etc.) were extracted.

Implications for Implementation:

Further evidence of different outcomes by ethnic group requiring systemic action across the health services.
