ARTICLE HIGHLIGHTS
Research background

Intensive care unit-acquired weakness (ICU-AW) is a common complication that significantly impacts the patient's recovery process, even leading to adverse outcomes. Currently, there is a lack of effective preventive measures.

Research motivation

Provide meaningful insights for the prevention of ICU-AW.

Research objectives

Identify the main risk factors for ICU-AW.

Research methods

Utilizing iterative machine learning techniques, a multilayer perceptron neural network model was developed, and its predictive performance for ICU-AW was assessed using the receiver operating characteristic curve, and analyzed the importance of independent variables in models.

Research results

The most influential factors contributing to ICU-AW were identified as the length of ICU stay (100.0%) and the duration of mechanical ventilation (54.9%). The neural network model predicted ICU-AW with an area under the curve of 0.941, sensitivity of 92.2%, and specificity of 82.7%.

Research conclusions

The main factors influencing ICU-AW are the length of ICU stay and the duration of mechanical ventilation.

Research perspectives

A primary preventive strategy, when feasible, involves minimizing both ICU stay and mechanical ventilation duration. Future research needs to clarify the mechanism of ICU-AW occurrence and refine prevention strategies.
