Guideline directed use of pharmacologic Venous thromboembolism (VTE) prophylaxis emphasizes
mobility evaluation. Mobility is a key component of risk stratification. Poor mobility
evaluation by providers may be a significant barrier to appropriate use of VTE prophylaxis.
The investigators aim is to propose to determine whether level of mobility during
hospitalization is being used to influence use and duration of VTE prophylaxis among
medically ill hospitalized elders. To achieve this aim, the investigator will collect
prospective observational data to objectively measure inpatient mobility using patient
mounted accelerometers during patient hospital stays.
The investigator's goal is to improve the appropriateness of use of VTE prophylaxis among
those in which the risks of harm may outweigh the benefit. Results from this study will
provide important insights about use of risk assessment, and the relationship between patient
mobility and VTE prophylaxis. These results are critical to understanding how to take the
next steps toward improving the appropriate use and safety of anticoagulants in hospitalized
older adults. Information from this study could be used in future proposals to study
interventions to ultimately improve hospital practice in the care of older adults.
