Lose the Whoosh: An Evidence-Based Project to Improve NG Tube Placement Verification in Infants and Children in the Hospital Setting

Purpose: The purpose of this EBP project was to align NG and OG tube placement and verification practices with evidence-based recommendations for children.

Practice Change: An evidence-based NG/OG Tube Placement Algorithm was developed. The algorithm provided an individualized approach based on patient condition as well as a tiered approach that incorporated radiographs, tube measurement and marking, and pH testing.

Methods: A systematic appraisal of literature identified 40 studies supporting the development of the practice change. A 9-item questionnaire was administered to nurses across five pediatric units to assess current tube verification practices. Education was provided in participating units through a Competency Fair. Post-implementation evaluation included re-administering the practice survey and conducting a chart audit of NG/OG events occurring in the year following the practice change.

Results: Seventy-one nurses completed the pre-implementation survey; 64 nurses completed the post-implementation survey. Strategies for checking NG/OG placement varied across units prior to implementation; however, auscultation was the most likely to be used strategy and assessing pH was the least likely to be used strategy across units. Post-implementation, aspiration and checking pH were the most frequently endorsed assessment strategy, and auscultation was the least endorsed strategy. The post-implementation chart audit revealed that 73% of NG/OG tubes were checked for placement on insertion with radiograph or aspirate pH.

Conclusions: Implementation of an NG/OG Tube Placement Algorithm standardized NG/OG care across five pediatric units. Additional efforts are underway to further improve adherence to protocol in order to ensure safe, evidence-based practice for children with NG/OG tubes.
