The tool contains 11 content categories reflecting topics of patient presentation, assessment, and professional environment and 11 language form categories representing information-seeking, information-giving, and information-verifying behaviors. The Handoff Communication Assessment showed good interrater reliability for content (κ=0.71) and language form (κ=0.84). We analyzed 742 utterances, which provided the following preliminary findings: emergency physicians talked more during handoffs (67.7% of all utterances) compared with hospitalists (32.3% of all utterances). Content focused on patient presentation (43.6%), professional environment (36%), and assessment (20.3%).
