Quantifying Patient-Level Factors Associated With Mobilisation in Intensive Care: A Prospective Study

To quantify how specific patient-level characteristics influence the actual amount of mobilisation received during ICU care, thereby identifying key predictors to support individualised mobilisation strategies.

A prospective observational study was conducted in four tertiary hospitals among a convenience sample of 141 critically ill patients from July to November 2023. Data on mobilisation and patient characteristics were collected using standardised data collection tools, including a mobilisation log and a demographic information sheet. Data were analysed using non-parametric tests, Spearman correlation analysis, and multivariate regression to examine associations between early mobilisation and patient-related factors.

Males and surgical patients engaged in more activity (p < 0.001). Muscle strength (r = 0.568, p < 0.001) and haemoglobin levels (r = 0.207, p = 0.014) were positively associated with mobilisation, while higher disease severity (r = -0.321, p < 0.001) and greater pain (r = -0.284, p < 0.001) were linked to reduced activity. Muscle strength, disease severity, surgical status, and sex were independent predictors, explaining 32.5% of the variance.

Early mobilisation in the ICU is influenced by various patient-related factors. Protocols should be tailored to individual patient profiles to enhance outcomes.

This study provides guidance for ICU clinicians to develop targeted mobilisation strategies that consider patients' specific clinical profiles. Tailored approaches may help optimise early mobilisation practices and patient outcomes.
