Abstract:
ob<x>jective: To explore the conversion relationship between subjective and ob<x>jective pain assessment tool scores in critical ill adults. Methods: The convenience sampling method was used to select 115 critically ill adults admitted to the ICU of a large general hospital from March 2021 to October 2021.Numerical Rating Scale (NRS), Critical-care Observation Pain Tool (CPOT) and Behavioral Pain Scale-China (BPS-C) were used to assess patients’ pain at rest ( 70) and during painful procedure (85), the correlation and conversion relationship between NRS and CPOT as well as NRS and BPS-C were analyzed. Results: Regardless of the status of patients, CPOT scores were significantly correlated with NRS scores (rrest=0.500-0.789, P<0.05) (rprocedure=0.482-0.922, P<0.05), so the linear regression equation between CPOT and NRS can be established: CPOTrest=0.122+0.442×NRS(R2=0.452), CPOToperation=0.932+0.486×NRS(R2=0.554). Regardless of the status of patients, BPS scores were also significantly correlated with NRS scores (rrest=0.478-0.814, P<0.05) (rprocedure=0.440-0.983, P<0.05), so the linear regression equation between BPS and NRS can be established: BPSrest=2.774+0.415×NRS(R2=0.420), BPSprocedure=3.288+0.519×NRS(R2=0.501). Conclusion:The linear regression equation can be used to convert the scores between NRS and CPOT as well as NRS and BPS, so that the pain assessment scores of critical ill adults can be standardized under the same scale. The regression equation established by NRS and CPOT has a better fit, and CPOT is more suitable for pain assessment in critically ill adults
