“…one patient's '8' might be another patient's '3' on a 1 -10 scale, suggesting that the scores on these tools are relative only to the sufferer and are not comparable across people (Ho, et al, 1996). One study also revealed that over 50% of nurses were concerned that such tools were subjective, inaccurate, and subject to problems of under-and over-treatment (Simons & MacDonald, 2004), a concern that is supported by empirical evidence that pain is often underestimated on the basis of these measures, especially at high levels (Sjötröm, Haljamäe, Dahlgren, & Lindström, 1997). This has obvious implications for treatment as if pain is underestimated then patients are likely to receive inadequate treatment and pain relief.…”
