Detailed Description:
Over the last few years the chance of dying from a heart attack in England and Wales has reduced dramatically. Even so, there remain huge differences in mortality between hospitals. For example, up to a third of patients with a heart attack who attend hospitals in England are more likely to die than would be expected. That is, the type of treatment and the risk of death depends upon where a patient lives and which hospital they attend. In part, the variation in death may be due to the services available at the hospital or to factors such as socioeconomic deprivation. It may also relate to other factors such as depression, cardiac rehabilitation and whether patients take their medication after discharge from hospital. Using powerful statistical approaches that include measures of quality of life, we propose to examine data about heart attacks in England and investigate the 'postcode lottery of care'. Our aim, using regional data about heart attacks is to identify and measure the effects of hospital care. This research will identify hospital qualities that promote improved patient care. In doing so, best practice will be highlighted and healthcare policy changed so that all patients will have an equal chance of surviving a heart attack.

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Consented patients with acute coronary syndrome were recruited from acute Trusts in England. These hospitals have been selected because of their diverse population demographics, different acute coronary syndrome care pathways and established track record for good data collection. Specifically these hospitals represent both teaching hospitals and community hospitals - but more importantly include a wide range of patient types. Mortality tracked through the UK statistics authority, and primary and secondary endpoints tracked locally and transferred through the secure NHS net to a central database.

Inclusion Criteria:

  • Age > 18 years
  • Both sexes
  • Acute admission to the acute Trust with suspected acute coronary syndrome

Exclusion Criteria:

  • Patients at a terminal stage of any illness
  • Those in whom follow up would be inappropriate or impractical
