The British Cardiovascular Intervention Society was founded in 1988 and represents cardiologists and allied health care professionals with an interest in interventional cardiovascular procedures in all countries of the United Kingdom. The Society promotes education, training and research in cardiovascular intervention and develops and upholds clinical and professional standards to try to ensure that all patients being treated by PCI get the best possible care (www.bcis.org.uk). We have therefore collected data about the way in which PCI is performed, and outcomes for patients following PCI, for many years. The data are publicly available on the Society’s web site and have focused on the performance of individual PCI centres. In recent years BCIS have collaborated with the National Institute of Cardiovascular Outcomes Research (NICOR) to collect and analyse these data.
While the main focus has been on the practice of PCI in different hospitals, in recent years we have also presented analyses of the practice of individual PCI consultant operators. In reading these analyses it is important to understand how they were generated so that their strengths and limitations can be recognised and the information seen in context.
These data have been provided by each centre and their PCI consultant operators. It is not possible for BCIS or NICOR to validate these data; their accuracy therefore rests with the PCI operators and the data collection personnel in the hospital where the PCI was performed.
For each PCI procedure over 100 data items are recorded. These include:
a) Information about the patient such as their age, sex and other conditions that they might be suffering from such as diabetes and hypertension.
b) The reason a patient needs to be treated by PCI. For example this might be for symptoms of stable angina or because they have presented to a hospital with sudden onset of chest pain due to a heart attack.
c) The way the PCI was performed, including the techniques employed and the equipment, stents and medications used.
d) How the patient got on after the PCI and whether there were any adverse events before they were discharged home.
