Development and validation of a nomogram for oral mucosal membrane pressure injuries in ICU patients: A prospective cohort study

Abstract Aims Establishing a nomogram to estimate the probability of oral mucosal membrane pressure injury of endotracheal tube‐intubated hospitalized patients in intensive care unit. Design Multicentre prospective cohort study. Methods Using Lasso regression and COX regression, variable selection was performed on demographic, clinical and laboratory data of 1037 ICU endotracheal tube‐intubated hospitalized patients from West China Hospital, to construct a nomogram. External validation was conducted on 484 ICU endotracheal tube‐intubated patients from People's Hospital of Zhongjiang County. Results Among 38 potential predictors, five variables emerged as independent predictors, integrated into the nomogram: administration of antibiotics, nutritional therapy duration, agitation, hypotension and albumin levels. Conclusions We established a nomogram based on the hospital characteristics of ICU endotracheal tube‐intubated patients, aiding in the prediction of the occurrence of oral mucosal membrane pressure injury. Reporting Method The study followed TRIPOD guidelines. Relevance to Clinical Practice The nomogram we developed can assist clinical worker in better identifying at‐risk patients and risk factors. It enables the implementation of evidence‐based nursing interventions in care to prevent the development of oral mucosal membrane pressure injury. Trial registration The study has been registered with the Chinese Clinical Trial Registry ( http://www.chictr.org.cn ) under registration number ChiCTR2200056615.
