Key result
A computerized audiovisual analogue scale was as reliable as a paper linear analogue scale for assessing postoperative pain and preoperative anxiety, demonstrating a strong correlation.
Why the study?
Does a computerised audiovisual analogue scale correlate with a linear analogue scale on paper for grading pain and anxiety?
Does a computerised audiovisual analogue scale correlate with a linear analogue scale on paper for grading pain and anxiety?
A computerized audiovisual analogue scale is as reliable as a conventional paper linear analogue scale for assessing pain and anxiety.
Supports digital alternatives for perioperative pain/anxiety assessment; leaves open workflow integration and outcome impact.
Comparison of a linear analogue scale on paper and a computerised audiovisual analogue scale presented on a visual display unit is described. Pain was assessed postoperatively in 109 patients and anxiety pre-operatively in 146 patients. Results show a strong correlation between gradings obtained using the two methods, indicating the computerised method is as reliable as the conventional one.
