Abstract

Introduction Avoiding low value medical practices is an important focus in current healthcare utilisation. Despite advantages of point-of-care ultrasound (POCUS) over chest X-ray including improved workflow and timeliness of results, POCUS-guided central venous catheter (CVC) position confirmation has slow rate of adoption. This demonstrates a gap that is ripe for the development of an intervention.

Methods The intervention is a deimplementation programme called DRAUP (deimplementation of routine chest radiographs after adoption of ultrasound-guided insertion and confirmation of central venous catheter protocol) that will be created to address one unnecessary imaging modality in the acute care environment. We propose a three-phase approach to changing low-value practices. In phase 1, we will be guided by the Consolidated Framework for Implementation Research framework to explore barriers and facilitators of POCUS for CVC confirmation in a single centre, large tertiary, academic hospital via focus groups. The qualitative methods will inform the development and adaptation of strategies that address identified determinants of change. In phase 2, the multifaceted strategies will be conceptualised using Morgan’s framework for understanding and reducing medical overuse. In phase 3, we will locally implement these strategies and assess them using Proctor’s outcomes (adoption, deadoption, fidelity and penetration) in an observational study to demonstrate proof of concept, gaining valuable insights on the programme. Secondary outcomes will include POCUS-guided CVC confirmation efficacy measured by time and effectiveness measured by sensitivity and specificity of POCUS confirmation after CVC insertion.

With limited data available to inform interventions that use concurrent implementation and deimplementation strategies to substitute chest X-ray for POCUS using the DRAUP programme, we propose that this primary implementation and secondary effectiveness pilot study will provide novel data that will expand the knowledge of implementation approaches to replacing low value or unnecessary care in acute care environments.

Ethics and dissemination Approval of the study by the Human Research Protection Office has been obtained.
