BACKGROUND: Early mobilisation (EM) of critically ill patients in intensive care units (ICUs) has gained significant attention because of its potential to improve patient outcomes. Despite the recognised benefits of EM, implementation remains inconsistent. OBJECTIVES: To describe the knowledge, attitudes and practices of healthcare professionals regarding EM of critically ill patients in Windhoek. METHOD: A descriptive, cross-sectional design using a self-administered survey was conducted in Windhoek, Namibia, targeting nurses, doctors and physiotherapists working in private ICUs. RESULTS: A total of 174 surveys were distributed, with a response rate of 24.1% ( CONCLUSION: Our study revealed knowledge gaps, conservative mobility practices and numerous barriers to EM implementation at the patient, provider and institutional levels. CLINICAL IMPLICATIONS: The findings highlight the need for targeted education, training programmes, standardised mobility protocols and the establishment of a dedicated mobility champion to promote EM in Windhoek ICUs.
