Feasibility and safety of Post-Urgent PCI Same-DaY discharge (PUSDY Trial) in China: protocol for a multicentre randomised controlled trial

Abstract

Introduction In the Chinese healthcare system, where there is overcrowding in hospitals, especially in tertiary care centres, adoption of same-day discharge (SDD) post-percutaneous coronary intervention (PCI) could potentially lead to significant savings of healthcare resources and costs. This study is a non-inferiority trial examining whether post-PCI SDD is feasible in China. The primary hypothesis is that patient outcomes in post-urgent PCI SDD patients are non-inferior to regular discharge patients.Methods and analysis Post-Urgent PCI Same-DaY is an investigator-initiated multicentre randomised unblinded clinical non-inferiority trial, with 1:1 centralised randomisation to the SDD or usual care (UC) group. Based on sample size calculations, 1296 patients from at least three hospitals, with mild to moderate myocardial infarction, will be included, and acute coronary syndrome patients will be excluded. All patients will receive UC while patients assigned to the SDD group will be discharged on the same day or within 12 hours post-PCI. The primary outcome is major adverse cardiovascular and cerebrovascular events 30 days after discharge. The secondary outcomes are all-cause mortality, bleeding and access site complications. The outcome rates will be compared between groups with the absolute risk difference with a 95% CI.Ethics and dissemination The study protocol V.2.0 has been approved on 21 January 2022 by the Ethics Committee of Beijing Anzhen Hospital, Capital Medical University (approval number: 2021 KLSD No. 23). The outcomes of this study will be disseminated through a peer-reviewed journal and presented at international conferences.Trial registration number ChiCTR 2200057065; China Clinical Trial Registration.
