Different scales can be used for patients to self\u2010report their pain, but research determining cut points between mild, moderate and severe pain has been limited to studies with &lt;\u20091500 patients. We examined 13,017 simultaneous acute postoperative pain ratings from 913 patients taken at rest and on activity, between 4\u2009h and 48\u2009h following surgery using both a verbal rating scale (no, mild, moderate or severe pain) and 0\u2013100\u2009mm visual analogue scale. We determined the best cut points on the visual analogue scale between mild and moderate pain as 35\u2009mm, and moderate and severe pain as 80\u2009mm. These remained consistent for pain at rest and on activity, and over time. We also explored the presence of category disagreements, defined as patients verbally describing no or mild pain scored above the mild\/moderate cut point on the visual analogue scale, and patients verbally describing moderate or severe pain scored below the mild\/moderate cut point on the visual analogue scale. Using 30 and 60\u2009mm cut points, 1533 observations (12%) showed a category disagreement and using 35 and 80\u2009mm cut points, 1632 (13%) showed a category disagreement. Around 1 in 8 simultaneous pain scores implausibly disagreed, possibly resulting in incorrect pain reporting. The reasons are not known but low rates of literacy and numeracy may be contributing factors. Understanding these disagreements between pain scales is important for pain research and medical practice.<\/jats:p>","DOI":"10.1111\/anae.16186","type":"journal-article","created":{"date-parts":[[2023,12,7]],"date-time":"2023-12-07T18:11:54Z","timestamp":1701972714000},"page":"139-146","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Comparing pain intensity rating scales in acute postoperative pain: boundary values and category disagreements"],"prefix":"10.1111","volume":"79","author":[{"given":"R.
