In 2001, 1176 US hospitals were capable of performing primary percutaneous coronary intervention (PCI), and 79% of the population lived within 60-minute ground transport of these hospitals. We compared these estimates with data from 2006 to explore how hospital PCI capability and population access have changed over time.
We estimated the proportion of the population 18 years of age or older, living in 2006 within a 60-minute drive of a PCI-capable hospital, and we compared our estimate with a previously published report on 2001 data. Over the 5-year period, the number of PCI-capable hospitals grew from 1176 to 1695 hospitals, a relative increase of 44%; access to the procedure grew from 79.0% to 79.9% of the population, a relative increase of 1%.
Our data indicate a large increase in the number of hospitals capable of performing PCI from 2001 to 2006, but this increase was not associated with an appreciable change in the proportion of the population with access to the procedure. In the future, more attention is needed on changes in PCI capacity over time and on the effects of these changes on outcomes of interest such as service utilization, expenditures, patient outcomes, and population health.
2001年，美国有1176家医院能够开展直接经皮冠状动脉介入治疗（PCI），79%的人口居住在距这些医院地面交通60分钟可达的范围内。我们将这些估计数据与2006年的数据进行比较，以探讨医院PCI能力和民众可及性随时间的变化情况。
我们估算了2006年居住在距具备PCI能力医院驾车60分钟范围内的18岁及以上人口比例，并将我们的估算结果与之前发表的关于2001年数据的报告进行比较。在这5年期间，具备PCI能力的医院数量从1176家增至1695家，相对增长了44%；该治疗的可及性从占人口的79.0%增至79.9%，相对增长了1%。
我们的数据表明，2001年至2006年期间能够开展PCI的医院数量大幅增加，但这一增加与接受该治疗的人口比例的显著变化并无关联。未来，需要更加关注PCI能力随时间的变化以及这些变化对诸如服务利用、支出、患者结局和人群健康等相关结局的影响。
