Perceived barriers to mobility in the intensive care units of Singapore: The Patient Mobilisation Attitudes and Beliefs Survey for the intensive care units
Purpose: Prolonged bed rest and immobility in the intensive care units (ICU) increase the risk of ICU-acquired weakness (ICUAW) and other complications. Mobilisation has been shown to improve patient outcomes but may be limited by the perceived barriers of healthcare professionals to mobilisation. The Patient Mobilisation Attitudes and Beliefs Survey for the ICU (PMABS-ICU) was adapted to assess perceived barriers to mobility in the Singapore context (PMABS-ICU-SG).
Methods: The 26-item PMABS-ICU-SG was disseminated to doctors, nurses, physiotherapists, and respiratory therapists working in ICU of various hospitals across Singapore. Overall and subscale (knowledge, attitude, and behaviour) scores were obtained and compared with the clinical roles, years of work experience, and type of ICU of the survey respondents.
Results: A total of 86 responses were received. Of these, 37.2% (32/86) were physiotherapists, 27.9% (24/86) were respiratory therapists, 24.4% (21/86) were nurses and 10.5% (9/86) were doctors. Physiotherapists had significantly lower mean barrier scores in overall and all subscales compared to nurses (p < 0.001), respiratory therapists (p < 0.001), and doctors (p = 0.001). A poor correlation (r = 0.079, p < 0.05) was found between years of experience and the overall barrier score. There was no statistically significant difference in the overall barriers score between types of ICU (χ2(2) = 4.720, p = 0.317).
Conclusion: In Singapore, physiotherapists had significantly lower perceived barriers to mobilisation compared to the other three professions. Years of experience and type of ICU had no significance in relation to barriers to mobilisation.
