A Clean You Can Trust: Using an Evidence-Based Bundle to Transform Point-of-Use Treatment for Reusable Medical Devices at a Military Treatment Facility

Introduction: Throughout surgical and invasive procedures, reusable instruments and flexible endoscopes become soiled with organic and inorganic materials. When these substances are permitted to dry, a matrix of microbial cells, called biofilm, forms on the surface of devices, irreversibly binding and subsequently impeding the disinfection and sterilization process. To prevent biofilm formation from occurring, devices must be continuously flushed and wiped with water throughout the procedure and at the end of the case. This process, known as point-of-use treatment (POUT), is the critical first step in the decontamination of medical devices. Poor compliance with POUT can increase patient morbidity and mortality and result in failing hospital accreditation. Materials and Methods: An interdisciplinary team used the Plan-Do-Study-Act (PDSA) to develop and implement an audit assessing 29 evidence-based criteria for POUT treatment. Each PDSA cycle supported evidence-based opportunities addressing feedback, workflow analysis, policy development, competency assessment creation, training module development, and infection prevention grand rounds. Four audits were performed over ten months to achieve improved organizational POUT compliance. Results: Implementing recurrent PDSA cycles that included audits with feedback led to an evidence-based bundle of policies, competencies, and training for 34 different clinical areas. These interventions resulted in a 26% compliance increase (66% to 92%). Program-specific improvements included flexible endoscopes (+4%) and reusable instruments (+20%). Conclusions: Multimodal evidence-based initiatives to improve compliance with workflow processes is a translatable POUT evidence-based practice project for similar Defense Health Agengy facilities. Workflow processes can be vetted and distributed using interdisciplinary teams to ensure viability, sustainability, and conformity with organizational requirements, resulting in a more ready force.
