Barriers and Challenges to the Successful Implementation of an Intensive Care Unit Mobility Program: Understanding Systems and Human Factors in Search for Practical Solutions.

ICU-acquired weakness is a common problem and carries significant morbidity. Despite evidence that early mobility can mitigate this, implementation outside of the research setting is lagging. Understanding barriers at the systems as well as individual level is a crucial step in successful implementation of an ICU mobility program. This includes taking inventory of waste, overburden and inconsistencies in the work environment. Appreciating regulative, normative as well as cultural forces at work is critical. Finally, key personnel, which include organizational leaders, innovation champions and end users of the proposed change need to be accounted for at each step during program implementation.
