It is crucial to elucidate the rates and causes of unplanned readmissions following percutaneous coronary interventions (PCI), in order to improve healthcare services in the field. Kwok et al. conducted a retrospective study on patients in the US Nationwide Readmission Database who underwent PCI. The primary aim of this study was to assess rates and causes of unplanned readmissions between 0 to 7, 8 to 30, 31 to 90 and 91 to 180 days after discharge following PCI.
Approximately 25% of the 2,412,000 included patients were readmitted within 6 months after PCI, with the majority of readmissions occurring within 30 days. The peak rate of unplanned readmissions occurred at 7 days post-discharge. Non-cardiac causes were the most common causes of readmission for all time points. In particular, unspecific chest pain was the most common cause of non-cardiac readmissions early on after discharge (22.7%), while gastrointestinal causes (11.9%) and infections (12.9%) were predominant at later time points (91 to 180 days). Among cardiac causes, AMI (acute myocardial infarction) was more prevalent between 0 to 7 days (27.9%), while readmissions due to heart failure peaked between 8 and 30 days after discharge (26.3%).
Future strategies aimed at reducing readmissions after PCI should consider the distribution of causes over time.
