'Errors' and omissions in paper-based early warning scores: the association with changes in vital signs--a database analysis.

Clifton DA, Clifton L, Sandu DM, Smith GB, Tarassenko L, Vollam SA, Watkinson PJ - BMJ Open (2015)

Bottom Line: To understand factors associated with errors using an established paper-based early warning score (EWS) system.We investigated the types of error, where they are most likely to occur, and whether 'errors' can predict subsequent changes in patient vital signs.Work is urgently needed to understand how best to capture this information.

Early warning score (EWS) system used by clinical staff throughout the study, including heart rate (HR, measured in bpm), breathing rate (BR, measured in respirations per minute), temperature (Temp, measure in degrees Celsius), systolic blood pressure (SBP, measured in mm HG), and SpO2 (%).

BMJOPEN2014007376F1: Early warning score (EWS) system used by clinical staff throughout the study, including heart rate (HR, measured in bpm), breathing rate (BR, measured in respirations per minute), temperature (Temp, measure in degrees Celsius), systolic blood pressure (SBP, measured in mm HG), and SpO2 (%).

Mentions: The EWS used in the ward throughout the study has been in standard practice for more than a year before the study began (figure 1) (note: the escalation protocol is provided in online supplementary appendix B). An observation set was deemed to have ‘alerted’ if any single vital sign was assigned a weight of 3, or if the aggregate score was 4 or more.
