BACKGROUNDAvoiding low value medical practices is an important focus in current healthcare utilization. Despite advantages of point of care ultrasound (POCUS) over chest x-ray (CXR), including improved workflow and timeliness of results, POCUS-guided central venous catheter (CVC) position confirmation and exclusion of pneumothorax (PCEP) has had slow rate of adoption. This demonstrates a gap that is ripe for the development and application of de-implementation strategies that support

Guided by the Consolidated Framework for Implementation Research constructs, we will explore barriers and facilitators of POCUS for CVC PCEP in a single center, large tertiary, academic hospital via focus groups. The focus groups will inform the development and testing of strategies that address identified determinants of implementation and de-implementation.Operational use of the de-implementation strategies will be conceptualized using Morgan's framework for understanding and reducing medical overuse. We will locally implement these strategies and assess them using Proctor's outcomes (adoption, de-adoption, fidelity and penetration) in an observational study to demonstrate proof of concept, gaining valuable insights on our selected implementation and de-implementation strategies. Secondary outcomes will include POCUS-guided CVC PCEP efficacy measured by time and effectiveness measured by sensitivity and specificity of POCUS detection.DISCUSSIONWith limited data available to inform interventions that use concurrent implementation and de-implementation strategies to substitute CXR for POCUS using DRAUP, we propose that this primary implementation and secondary effectiveness pilot study will provide novel data that would expand the knowledge of replacing low value or unnecessary care in critically ill patients.
