Same Day Versus Next Day Discharge: Ambulatory Closure Device Percutaneous Intervention

Overview

This is a multi-center trial that will evaluate the safety, feasibility, and cost effectiveness of discharging patients, who have had successful percutaneous coronary intervention (PCI) and deployment of the AngiomaxTM closure device, 6 hours after against 24 hours after the procedure. Patients will be randomized in a 3 (test): 1 (control) fashion and will have a study population of 600 patients over 6 investigational sites all within the United States. Patients \<65 years old will be chosen in order to stay within the low risk group and will be followed up after 24 hours, 7 days, and 30 days via phone or office visit. The primary endpoint will be a composite of major adverse cardiac and cerebral events, and the incidence of major bleeding or vascular complications. Data acquired from the study, such as blinded financial information and patient satisfaction surveys, will be used in order to evaluate cost analysis and safety of the procedure.

Closure devices are a relatively new method for sealing the femoral arterial puncture following procedures including percutaneous intervention (PCI). Because the risk of severe complications (e.g., bleeding, myocardial infarction, stroke, and mortality) associated with PCI when closure devices are very low, many patients undergoing PCI may be considered eligible for a same day hospital discharge. As the practice of ambulatory PCI is becoming more common, it is important to evaluate the readiness of patients under-going PCI for same-day discharge and anxiety and coping abilities of patients post-discharge. Our hypothesis is that same day discharge of patients who have undergone a PCI procedure with closure using a vascular closure device is safe, patients will be comfortable with a same day discharge and this process will be more cost efficient than the current standard of staying in the hospital overnight. The current pilot study is a multi-center, randomized parallel arm, controlled trial of low-risk patients undergoing an elective PCI procedure. Overall, 600 patients will be enrolled. After providing informed consent, participants will be randomized to leave the hospital on the same day as the PCI procedure or stay overnight in a 1:1 ratio. Data collection includes a self-administered questionnaire at hospital discharge, telephone interviews at 7-days and 30-days post-hospital discharge, and chart abstraction. The primary outcome for this study is differences across randomization arm in patient satisfaction scores on the validated 10-item Post-discharge coping difficulty scale assessed 7 days post-discharge. Secondary outcomes will include differences across randomization group for symptoms of anxiety, readiness for hospital discharge, patient satisfaction with the timing of their discharge, post-procedure pain and soreness, and cost-savings. While a data safety monitoring board will track all adverse events (i.e., myocardial infarction, hematoma, hospitalizations, and mortality), we anticipate too few events to occur to make meaningful inferences beyond that PCI is safe regardless of the timing of hospital discharge. The data from this pilot study will determine the comfort patients experience after undergoing PCI with an ambulatory (i.e, same-day) hospital discharge. Furthermore, this pilot study will provide the foundation for a large scale non-inferiority study of same-day discharge on outcomes including myocardial infarction, bleeding, and mortality. Such data will indicate the overall feasibility of early ambulatory PCI and has the potential to radically alter health care delivery following PCI.
