Implementation of an accelerated discharge process following percutaneous coronary intervention for patients with non-ST elevation acute coronary syndromes

Historically, patients with non-ST elevation acute coronary syndrome (NSTE-ACS) are monitored as inpatients following successful percutaneous coronary intervention (PCI), but accumulating evidence demonstrates that accelerated discharge is safe, reduces cost, and enhances patient satisfaction. This quality improvement project examined the impact of implementing a post-PCI streamlined discharge process for NSTE-ACS patients on length of stay (LOS), major adverse cardiovascular events, and provider utilization at a university-affiliated hospital system.

Clinical characteristics, the timing of admission, PCI, and discharge data were collected prospectively from patients presenting to the catheterization laboratory for intervention for NSTE-ACS during 90-day historical control and implementation periods. The knowledge to action implementation model was employed to establish a peer-coaching based educational tool for educating interventional cardiologists and inpatient clinicians regarding patients with low-risk characteristics suitable for same-day discharge (SDD) following PCI. Patient characteristics were similar between the historical and implementation periods. Although total hospital LOS did not decrease (51 ± 24 vs. 41 ± 18 h; P = 0.14), the discharge process reduced LOS after PCI among low-risk patients (22 ± 6 vs. 17 ± 8 h; P = 0.003). Complication and readmission rates were unchanged by SDD. Provider utilization of the discharge process increased four-fold during the implementation period (8% vs. 32%; P = 0.02).

Implementation of an accelerated discharge process following PCI for low-risk NSTE-ACS patients reduced post-PCI LOS without increasing readmissions or complications. Increased utilization of the process throughout the implementation period may be attributed to peer coaching.
