Development of a Mobile Monitoring and Communications Solution for Anesthesia Team Members Matthias Görges1, PhD and J Mark Ansermino2, MBBCh, FFA (SA), FRCPC Departments of 1Electrical & Computer Engineering and 2Anesthesiology, Pharmacology & Therapeutics, The University of British Columbia, Vancouver, BC, Canada

»Setting: BC Children’s Hospital uses a central

monitoring station for its operating rooms (ORs). This station integrates vital signs and alarms from eight ORs and multiple remote locations.

»Problem: Currently, anesthesia team members

use one-way numeric pagers to exchange messages. This has three drawbacks: »1) Monitoring data is available only in an office separate to the ORs. »2) The paging system only transmits a callback number but nothing on priority or patient. »3) The distance of the phone from the anesthesia workstation makes paging cumbersome.

»Solution: To improve information exchange, and

simplify communication between anesthesia team members, a monitoring and messaging application using a wireless mobile device is proposed.

Method »A work domain analysis (WDA) [1] of the

anesthesia assistant environment identified three main functions of the mobile device [2]: »Vital signs display »Room subscription/authentication »Messaging

»Based on the hierarchical model obtained through the WDA, paper prototypes were developed using a participatory rapid prototyping process [3].

Results

»The proposed mobile application will improve

patient safety by facilitating information exchange and communication between anesthesia team members. »Location independent access to information will also improve situational awareness [4].

»Future work: Implementation of the user

interface on a mobile device such as a smart phone. Development of a server component for information gathering, message exchange, and alert/reminder generation.
