AMP Step Wedge Trial

Annually, more than 35 million patients are hospitalized in the United States. Many of these will experience hospital-acquired loss of physical functioning due to a lack of mobility during their in-patient stay. Such loss includes difficulties performing basic activities, such as rising from a chair, toileting, or ambulating. This loss of function may increase hospital length of stay (LOS), nursing home placement, and decrease mobility and participation in community activities even years after hospitalization. Prevention of this hospital-acquired functional loss is critical. Even the sickest hospitalized patients (e.g., those in the intensive care unit \[ICU\]), can safely and feasibly benefit from early mobilization. In the non-ICU setting there is evidence that patient mobilization reduces LOS and hospital costs, while improving patient satisfaction and physical and psychological outcomes. The overall objective of this proposed project is to evaluate the implementation and impact of a transdisciplinary and multifaceted mobility program (Johns Hopkins Activity and Mobility Promotion - AMP) on clinical outcomes among hospitalized adults. In addition to clinical outcomes, we will identify barriers and facilitators to high-performance program adoption. Results of this project will provide critical new insights on the effectiveness of AMP and inform dissemination and implementation nationwide.
