  Minimum Data Set




Acute hospitalization, particularly for older adults, can have profound and persistent consequences on physical function. 1,2 Many studies have reported declines in physical function during and after an acute hospital stay with functional deficits persisting at least a year following hospitalization. 3–5 Sustained deficits in physical function are an important risk factor for several adverse post-hospitalization outcomes.

Inconsistent assessment of physical function has hampered our ability to learn what interventions ought to be implemented to maximize physical function across the continuum of care settings.

Our long-term goals

  1. Define a process for consistent physical function data collection beginning in the acute hospital and following patients as they proceed to post-acute care settings and return to community living
  2. Create a place for those data to be shared and used for understanding and improving long-term changes in physical function.

Our team, with representatives from University of Utah Health, Johns Hopkins Medicine, and the Cleveland Clinic received pilot funding to help define a standard data tool kit for longitudinal tracking of physical function from acute care hospitalization through post-acute care settings and into the community. Defining the tool kit involved facilitating consensus from key stakeholders including rehabilitation therapists, case managers, discharge planners, registered nurses, administrators, patients and a core group of experts.

The purpose of this website is to share the current tool kit with other interested health systems and individuals and to provide a mechanism for discussion and input. This tool kit represents a first step in standardizing a minimum set of data to collect in the inpatient and home health settings only. We anticipate including other care settings in the future.
