Validity of the current risk assessment scale for pressure ulcers in intensive care (EVARUCI) and the Norton-MI scale in critically ill patients

摘要

Abstract Objective The objective of this study was to evaluate the validity of risk detection scales EVARUCI and Norton-MI (modified by INSALUD) to detect critical adult patients with the risk of developing pressure ulcers (PU) in an intensive care unit (ICU). Design The authors have conducted a descriptive, prospective study at the ICU in their hospital from 2008 to 2014. The evaluations of both scales were registered daily by nurses from the unit. Patients Adult patients admitted into the ICU. Main outcomes measure The study measured the sensitivity, specificity, positive predictive values (PPV) and negative predictive values (NPV) of each of the scores for both scales and areas under curve (AUC) of receiver operating characteristics (ROC). Main results The authors have evaluated a total of 2534 patients. For the cut-off point recommended by the authors in the scale Norton-MI (PC 14), a sensitivity of 94,05% (93,28–94,82) was obtained, specificity of 40,47% (39,72–41,22), VPP 26,22% and VPN 96,80%. For EVARUCI (CP 10) a sensitivity of 80,43% (79,15–81,72), specificity 64,41 (63,68–65,14), VPP 33,71% and VPN of 93,60%. The ABC-COR was 0,774 with a 95% CI of 0,766 to 0,781 for the scale of Norton-MI and 0.756 with a 95% CI of 0,749 to 0,764 for EVARUCI. Conclusion Both scales are valid to help predict the risk of developing PU in critical patients. The sensitivity and ABC-COR are very similar for EVARUCI and Norton-Mi.
