Outcomes of an expedited same-day discharge protocol following cardiac implantable electronic device (CIED) implantation.

Abstract

With increasing constraints on healthcare resources, greater attention is being focused on improved resource utilization. Prior studies have demonstrated safety of same-day discharge following CIED implantation but arelimited by vague protocols with long observation periods. In this study, we evaluate the safety of an expedited 2hour same-day discharge protocol following CIED implantation. Patients undergoing CIED implantation at three centers between 2015 and 2021 were included. Procedural, demographic, and adverse event data were abstracted from the electronic health record. Patients were divided into same-day discharge (SDD) and delayed discharge (DD) cohorts. The primary outcome was complications including lead malfunction requiring revision, pneumothorax, hemothorax, lead dislodgement, lead perforation with tamponade, and mortality within 30days of procedure. Outcomes were compared between the two cohorts using the χ2 test. A total of 4543 CIED implantation procedures were included with 1557 patients (34%) in the SDD cohort. SDD patients were comparatively younger, were more likely to be male, and had fewer comorbidities than DD patients. Among SDD patients, the mean time to post-operative chest X-ray was 2.6h. SDD had lower rates of complications (1.3% vs 2.1%, p = 0.0487) and acute care utilization post-discharge (9.6% vs 14.0%, p < 0.0001). There was no difference in the 90-day infection rate between the cohorts. An expedited 2hour same-day discharge protocol is safe and effective with low rates of complications, infection, and post-operative acute care utilization.
