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

Abstract

Aim: 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.

Study design: 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.

Results: 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.

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

Implications for clinical practice: 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.
