Groups/Cohorts Assigned Interventions
patients hospitalized for longer than 24 hours and are located on the 4th, 5th, and 6th floors of the Vanderbilt University Medical Center Round Wing
Other: Rapid Response Team
If the subject is experiencing a life threatening change in their vital signs, the Rapid Response Team will be initiated per VUMC protocol.
Other Name: - attending nurse action per VUMC protocol

Detailed Description:

Approximately 150 patients will have wireless monitors attached to their arm. They will have their vital signs filtered through software that generates alerts and records data. The alert engine will produce pager and application based pop-up alerts which will be sent to the research nurse. Low and high limit alarms will be set according to the published guidelines (Hillman, K. et. Al., Resuscitation 48(2): 105-10, 2001) and adjusted at will by the response team.

During this portion of the study, the following research related procedures will be performed:

  • begin continuous vital signs monitoring (BP - 1x per hour, 3 lead ECG -continuous, HR - continuous, SpO2 - continuous)
  • PI or Co-PI will review each alert that's generated. The clinical significance will be determined and recorded in the study database
  • Record patient's signs and symptoms daily
  • Assess concomitant
  • Assess AE's, SAEs

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
