Cardiac-catheterization and cardiac-surgical facilities: use, trends, and future requirements
Insights
Cardiac catheterization and surgery rates are leveling off, but regional disparities persist. Many hospitals perform too few procedures for optimal results, suggesting a need to control cardiac center growth and evaluate service use.
Area of Science:
- Cardiovascular Medicine
- Health Services Research
Background:
- Cardiac catheterization and surgery are crucial diagnostic and therapeutic procedures.
- Understanding trends in utilization and regional variations is essential for healthcare planning.
Purpose of the Study:
- To evaluate trends in cardiac catheterizations and cardiac operations in Olmsted County, Minnesota, from 1973-1980.
- To compare regional trends with nationwide data and assess procedural volumes in hospitals.
Main Methods:
- Analysis of cardiac catheterization and operation data from Olmsted County, Minnesota.
- Comparison of regional data with national trends using multiple data sources.
- Evaluation of hospital procedural volumes against recommended minimums.
Main Results:
- Cardiac catheterization and coronary artery bypass graft (CABG) operation rates increased in Olmsted County but appeared to level off overall.
- Nationwide trends showed similar patterns, but significant regional differences in procedure rates were observed.
- In 1980, a substantial percentage of hospitals performed below recommended minimums for cardiac catheterization and open-heart surgery.
Conclusions:
- Further expansion of cardiac centers should be discouraged.
- Continuous evaluation of cardiac services is necessary to maintain quality of care and control costs.
- Addressing regional disparities and ensuring adequate procedural volumes are critical for optimal patient outcomes.
Abstract:
Cardiac catheterizations and cardiac operations were evaluated in the population of Olmsted County, Minnesota, from 1973 through 1980, and trends in this region were compared with nationwide trends based on data from several sources. The rates of coronary arteriography and coronary-artery bypass operations in Olmsted county have increased over time, but overall, the rates of catheterization and operation appeared to be leveling off. For the country as a whole, the data appear to show similar trends, but there are wide differences among regions in the rates of operation and catheterization. In 1980 40 per cent of hospitals with cardiac-catheterization laboratories and 55 per cent of those with facilities for open-heart surgery were doing fewer than the suggested minimum numbers of these procedures necessary to achieve optimum results. The data support the view that further growth in the number of cardiac centers should be avoided. We believe there is a need for continued evaluation of the use of cardiac services if quality is to be protected and costs controlled.
