C-21 | The use of intravascular ultrasound (IVUS) during percutaneous coronary intervention does not reduce all cause in-hospital mortality but doubles the cost with higher utilization in privately insured patients

The effect of using intravascular ultrasound (IVUS) during percutaneous coronary intervention (PCI) on short-term mortality is not well established. The goal of this study was to evaluate any association between the use of IVUS during PCI on mortality vs no ICUC in a large inpatient database. We used the National Inpatient Sample (NIS) database for available ICD-10 codes from 2016-2020 for IVUS and PCIs. A total of 10, 059, 56 PCIs were performed. 206, 910 underwent IVUS-guided PCI vs 9, 852, 359 without IVUS use. Mortality did not differ between the two groups with 2. 52% mortality in the IVUS arm vs 2. 59% in no IVUS cohort, p=0. 4. The mean age of patients with ICUS use was 65. 5 vs 70. 1 years without IVUS. Total in-hospital cost in the IVUS group was double that without IVUS (141, 920 vs 71, 568). Furthermore, IVUS utilization was significantly higher in patients with private HMO patients (28. 3% vs 17. 2%). In-patient all-cause mortality using IVUS during PCI was similar to those patients without IVUS utilization but doubled the cost with higher utilization in privately insured patients
