Use of the cardiac-catheterization laboratory in a defined population
Insights
Cardiac catheterization laboratory use significantly increased from 1973 to 1977, driven by coronary arteriography. A population of 230,000 is needed for optimal laboratory utilization.
Area of Science:
- Cardiovascular Medicine
- Medical Economics
Background:
- Cardiac catheterization laboratory utilization trends are crucial for resource planning.
- Understanding regional variations in diagnostic procedure use is essential.
Purpose of the Study:
- To analyze trends in cardiac catheterization laboratory use from 1973 to 1977.
- To determine the population base required for efficient laboratory operation.
Main Methods:
- Retrospective analysis of cardiac catheterization laboratory visits.
- Evaluation of procedures including coronary arteriography and left ventriculography.
- Population-based rate calculation per 10,000 individuals.
Main Results:
- Total catheterization laboratory visits increased from 4.3 to 11.5 per 10,000 population.
- Coronary arteriography rates more than quadrupled during the study period.
- Cardiac catheterization rates remained relatively stable.
- An estimated population of 230,000 is needed for 300 adult examinations annually.
Conclusions:
- Significant growth in cardiac catheterization laboratory procedures, particularly coronary arteriography, was observed.
- Substantial population support is necessary to maintain recommended procedural volumes.
Abstract:
We evaluated trends in the use of the cardiac-catheterization laboratory from 1973 through 1977 in a well-circumscribed population in southeastern Minnesota. A total of 346 patients (248 male and 98 female patients) underwent coronary arteriography, left ventriculography, or cardiac catheterization, and there were 369 visits to the catheterization laboratory. The total number of catheterization-laboratory visits per 10,000 population increased from 4.3 in 1973 to 11.5 in 1977. According to individual category, the rates for coronary arteriography increased more than fourfold during the five-year period, whereas the rates for cardiac catheterization period, whereas the rates for cardiac catheterization showed no substantial change. On the basis of the 1977 rate for all visits to the catheterization laboratory and under conditions similar to those in this community, a population of approximately 230,000 would be required to ensure use of a catheterization laboratory at the suggested minimum level of 300 adult examinations per year.
