Insights
Regional differences in invasive coronary procedures are significant in Norway. Incidence rates for percutaneous interventions in Vestfold were similar to the national average in 2001 but 30% lower in 2003, highlighting the need for localized planning.
Area of Science:
- Cardiovascular medicine
- Interventional cardiology
- Public health
Context:
- Limited data exists on regional variations in acute and elective invasive coronary procedures in Norway.
- Understanding these differences is crucial for planning new cardiac catheterization laboratories.
- This study focuses on the county of Vestfold and its referral patterns to a major hospital in Oslo.
Purpose:
- To investigate the incidence of acute and elective invasive coronary procedures in the county of Vestfold, Norway.
- To compare local procedure rates with national averages.
- To inform the planning of peripheral catheterization laboratory capacity based on regional needs.
Summary:
- A prospective study included 760 patients referred for coronary angiography from Vestfold (2002-2003).
- Of 746 undergoing angiography, 19% were acute referrals. Percutaneous coronary interventions (PCI) were performed on 295 patients (31% acute), and coronary artery bypass grafting (CABG) on 123.
- Incidence rates for PCI in Vestfold were comparable to the 2001 national average but 30% lower than the 2003 national average.
Impact:
- The findings reveal significant regional disparities in the utilization of invasive coronary procedures.
- Accurate population basis calculations are essential for optimal peripheral catheterization laboratory planning.
- This study underscores the importance of local incidence data for healthcare resource allocation in interventional cardiology.
Background:
Little is known about regional differences in the incidence of acute and elective invasive coronary procedures in Norway. Such information is important in the planning of new invasive centres.
Materials And Methods:
In this prospective study all patients referred to coronary angiography at the Rikshospitalet University Hospital in Oslo (100 km remote) from the county of Vestfold (218,000 inhabitants) from 1 December 2002 to 30 November 2003 were included. Referrals were categorised as acute or elective. Based upon the discharge summaries from Oslo, all coronary angiographies, percutaneous interventions and coronary artery bypass grafts were registered.
Results:
A total of 760 patients were referred, of whom 746 (98 %) underwent coronary angiography (19 % acutely). They were treated as follows: percutaneous coronary intervention, n = 295 (31 % acutely); coronary artery bypass grafting, n = 123 and conservative treatment, n = 342.
Interpretation:
Based upon these results, the incidence figures for 100,000 inhabitants per year in 2003 were similar to the nation-wide average for percutaneous interventions per year in Norway in 2001 and approximately 30 % below that average for 2003. Therefore, in the planning of an optimal peripheral catheterisation laboratory, the population basis has to be calculated from the local incidence of procedures, since there are obviously significant regional differences in the use of such procedures.
