Accuracy and Interrater Agreement of Registered Nurses' Assignment of Apgar Scores to Standardized Clinical Vignettes

The purpose of our study was to test whether registered nurses assign the correct Apgar score when provided all pertinent data, whether they assign an Apgar score even if all pertinent data are not provided, and to evaluate the Apgar score's interrater agreement. We conducted a REDCap survey and provided nurses with color photograph/vignette combinations of neonates, some of which lacked pertinent data points needed to correctly assign Apgar scores. Over 90% of study participants assigned Apgar scores even if data points for heart rate or respiratory effort were omitted. Participants' correct assignment of the component score for respiratory effort was affected by the description of the respiratory effort and whether neonatal heart rate was known. Interrater agreement was generally low to moderate. Our findings are consistent with earlier findings and support the conclusion that the Apgar score requires significant revision or needs to be retired and replaced.
