Background: Quality indicators (QIs) have been developed to improve and standardize care quality in percutaneous coronary intervention (PCI). In Japan, consecutive PCI procedures are registered in a nationwide database (the Japanese Percutaneous Coronary Intervention registry), which introduces a benchmarking system for comparing individual institutional performance against the national average. Objectives: The aim of this study was to assess the impact of the benchmarking system implementation on QI improvement at the hospital level. Methods: A total of 734,264 PCIs were conducted at 1,194 institutions between January 2019 and December 2021. In January 2018, a web-based benchmarking system encompassing 7 QIs for PCI at the institutional level, including door-to-balloon time and rate of transradial intervention, was introduced. The process by which institutions tracked their QIs was centrally monitored. Results: During the 3-year study period, the benchmarking system was reviewed at least once at 742 institutions (62.1%) (median 4 times; Q1-Q3: 2-7 times). The institutions that reviewed their records had higher PCI volumes. Among these institutions, although door-to-balloon time was not directly associated, the proportion of transradial intervention increased by 2.3% in the system review group during the initial year compared with 0.7% in their counterparts. However, in the subsequent year, the association between system reviews and QI improvement was attenuated. Conclusions: The implementation of a benchmarking system, reviewed by participating institutions in Japan, was partially associated with improved QIs during the first year; however, this improvement was attenuated in the subsequent year, highlighting the need for further efforts to develop effective and sustainable interventions to enhance care quality in PCI.
