Condition Intervention
Desaturation Bradycardia Tachycardia Hypertension Hypotension Other: Rapid Response Team (NTX wireless monitoring system)

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Validation of the NTX Wireless Patient Monitoring System in Combination With Novel Computer Interface to Generate Proactive Medical Responses to Patient Specific Events

Further study details as provided by Dan France, Vanderbilt University:

Primary Outcome Measures:
  • To determine if the NTX wireless monitoring system in combination with a novel computer interface will provide early detection of potentially life threatening changes in patient's vital signs [ Time Frame: an interim analysis will be performed after 400 patients have been placed on the study, again after 800 have been places on the study ]

Enrollment: 1303
Study Start Date: March 2008
Study Completion Date: January 2010
Primary Completion Date: January 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Other: Rapid Response Team (NTX wireless monitoring system)
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:
1200 patients will have wireless monitors attached to their arm. They will be randomized to have their vital signs filtered through software that generates alerts, or software that does not generate alerts. Low and high limit alarms will be set according to published guidelines and adjusted at will by the response team. If appropriate the Vanderbilt University Medical Center Rapid Response team will be initiated per Institutional Policy
