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

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

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.

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.

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.

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.
