Insights
Cardiac catheterisation and percutaneous coronary intervention (PCI) rates increased in Ireland from 2004-2011. However, age-adjusted PCI trends showed a non-significant decrease, highlighting divergent temporal patterns in cardiovascular interventions.
Area of Science:
- Cardiovascular medicine
- Public health
- Health services research
Background:
- Cardiac catheterisation and percutaneous coronary intervention (PCI) are key procedures for diagnosing and treating coronary heart disease.
- Understanding temporal trends in these interventions is crucial for healthcare planning and resource allocation.
Purpose of the Study:
- To analyze temporal trends in crude and age-standardized rates of cardiac catheterisation and PCI in Ireland between 2004 and 2011.
- To compare Ireland's PCI trends with international benchmarks.
Main Methods:
- Utilized two data sources: hospital surveys for procedure volumes and anonymized Hospital In-Patient Enquiry (HIPE) data.
- Calculated age-standardized rates to account for population demographic changes over time.
Main Results:
- Crude rates of angiography and PCI increased significantly from 2004 to 2011.
- Age-standardized PCI rates exhibited a non-significant decrease.
- The ratio of PCI to angiography decreased, with a majority of PCIs performed for stable coronary heart disease.
Conclusions:
- While overall angiography and PCI use has risen, crude and age-adjusted PCI trends diverge.
- Ireland shows a higher proportion of PCI for stable coronary heart disease compared to the USA and UK.
- Limited systematic surveillance of cardiological interventions in Europe hinders benchmarking Ireland's progress.
Background/Objectives:
To study temporal trends in crude and age standardised rates of cardiac catheterisation and percutaneous coronary intervention (PCI) in Ireland, 2004-2011.
Methods:
Two data sources were used: a) a survey of publicly and privately funded hospitals with cardiac catheter laboratories to obtain the annual number of procedures performed and b) anonymised data from the Hospital In-Patient Enquiry (HIPE) for angiography and PCI in acute publicly funded hospitals; age standardised rates were calculated to study trends over time.
Results:
From 2004 to 2011 the crude rate of angiography and PCI increased by 47.8% and 35.9% respectively, with rates of 6689 and 1825 per million population in 2011. Following age standardisation, however, PCI activity showed a non-significant decrease over time. The PCI to angiography ratio decreased from 30% to 27% and PCI was performed predominantly for stable coronary heart disease (54%) in 2011.
Conclusion:
Angiography and PCI rates have increased in Ireland but PCI crude and age adjusted rates show divergent trends. While Ireland differs from USA and UK, with a higher proportion of PCI being performed for stable CHD in recent years, little systematic surveillance of cardiological interventions within Europe is available to benchmark improvements in Ireland.
