Introduction
Pain in the critically ill affects nearly 50% of patients. In patients unable to self-report pain, behavioural scales are used. The aim of this study was to validate the Polish version of the Critical Care Pain Observation Tool (CPOT).

Material and methods
The prospective observational cohort study included patients observed during non-nociceptive and nociceptive procedures, at rest, during the intervention, and 15 min after each intervention. Assessments included self-report by patients and CPOT assessment carried out by two blinded observers.

Results
A total of 71 patients were included in the study (mean age: 66 years), predominantly males (50/71, 70%), mean APACHE II score 26.04 ±10.56. Results showed an excellent inter-rater correlation (ICC) between raters (ICC scores > 0.97). Self-report NRS (numeric rating scale) scores were available from 58/71 patients (82%). Patients’ self-reported pain and CPOT showed a very strong correlation (Spearman’s R > 0.85, p < 0.0001). The CPOT has high diagnostic value for detection of presence of patients’ self-reported pain (ROC AUC = 0.938 for rater A and 0.951 for rater B, p < 0.0001). CPOT score ≥ 2 is an optimal cut-off to detect pain during a nociceptive procedure. A significantly higher mean CPOT score during a nociceptive procedure as compared to a non-nociceptive procedure or at rest was found (p < 0.0001).

Conclusions
This study shows that the Polish version of the CPOT can be used to assess pain in critically ill patients with no hypnotic, opioid-based analgo-sedation. Polish CPOT scores correlated well with patients’ self-reported presence of pain and showed excellent inter-rater reliability. This makes the Polish version of the CPOT a reliable pain assessment tool.
