To examine the distribution of interventional cardiac catheterization laboratories, their case load, the time trends, and the regional variation of percutaneous transluminal cutaneous angioplasty (PTCA) utilization in Italy.
Analysis of data was provided by the annual reports of the Italian Group of Studies and Interventional Cardiology over the period from 1983 to 1996.
The number of PTCA facilities and their use steadily increased, mainly in the North. In 1996 the utilization rate was 34 per 100,000 population, but only 60% of labs performed 200 or more procedures.
Dramatic time trends and regional variations often took place without an epidemiology and technology assessment-based planning process.
研究意大利介入性心导管实验室的分布、病例数量、时间趋势以及经皮腔内冠状动脉成形术（PTCA）使用情况的地区差异。
分析意大利介入性心脏病学研究组1983年至1996年期间的年度报告所提供的数据。
PTCA设施的数量及其使用量稳步增加，主要集中在北部地区。1996年，其使用率为每10万人34例，但只有60%的实验室开展了200例或更多手术。
在缺乏基于流行病学和技术评估的规划过程的情况下，经常会出现显著的时间趋势和地区差异。
