AIMS: With advancement in technology, the number of percutaneous coronary interventions performed are rising. The goal of this study was to evaluate nationwide trend over a long period of time in the utilisation of percutaneous coronary intervention (PCI) using a large database. METHODS AND RESULTS: The Nationwide Inpatient Sample (NIS) database was utilised to calculate the age-adjusted rate for PCI from 1988 to 2004. Specific ICD-9-CM codes for all PCIs were used to compile the data. The NIS database contained 1,747,736 patients who had PCI performed from 1988 to 2004. The mean age for these patients was 63.75+/-11.07 years old. From 1988, the age-adjusted rate for all PCI gradually increased to more than three times until 2001 (80.3 per 100,000 [95%CI=71.86-88.92] in 1988 and 244 per 100,000 [95%CI=221.31-266.39, p<0.01] in 2001), but remained relatively unchanged (slight decline in the last few years of the study) until the end of the study (232.17 per 100,000 95%CI=211.69-252.66) in 2004. These trends were similar across ethnicity, gender and comorbid conditions. CONCLUSIONS: The utilisation of PCI has dramatically increased from 1988 to 2001, but remained steady thereafter. The availability of drug eluting stents in the USA after 2001 may have contributed to this trend.
