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

Aims Design Methods Results Conclusions Reporting Method Relevance to Clinical Practice Trial registration Establishing a nomogram to estimate the probability of oral mucosal membrane pressure injury of endotracheal tube‐intubated hospitalized patients in intensive care unit.Multicentre prospective cohort study.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.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.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.The study followed TRIPOD guidelines.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.The study has been registered with the Chinese Clinical Trial Registry (http://www.chictr.org.cn) under registration number ChiCTR2200056615.
