Research on the nocebo effect has shown that some words can hurt. Pain is defined as 'unpleasant' and 'associated with actual or potential tissue damage'. So, a sensation described as 'pain' may function as a negative suggestion or nocebo communication. This can lead to pain being experienced or exacerbated where it would not have been otherwise. The nocebo effect has also been implicated as adversely affecting the pain experience during the assessment of pain postoperatively. Words that avoid this potential nocebo effect such as 'comfort' may represent a more satisfactory alternative. We therefore aimed to determine whether 'comfort' and 'pain' scores correlate when assessing patients postoperatively at the same timepoint. Patients were questioned before routine post-anaesthesia rounds to rate their pain and comfort levels, with the sequence of questions randomised. Patients were asked to rate pain and comfort on a 0-10 verbal numerical rating scale, where 0 represents 'no pain' or 'no comfort' and 10 'worst pain' or 'most comfort' imaginable, respectively. To provide a clinically relevant correlation of approximately 0.7 between pain and inverted comfort scores, a sample size of 100 would provide adequate precision (95% confidence interval (CI) 0.58-0.79). A P-value of <0.05 was considered significant. We recruited 100 patients. A positive correlation of 0.62 was found between pain and inverted comfort scores (95% CI 0.47-0.72; P<0.0001). The question sequence of asking about pain or comfort did not affect either score. Comfort and pain scores are moderately correlated. This finding represents a first step in validating comfort scores and suggests that they could be considered a suitable alternative to pain scores when assessing patients postoperatively. As comfort is not an exact antonym to pain, caution is required when using these measures interchangeably. [ABSTRACT FROM AUTHOR] |
