Mobile computers (MCs) at the bedside increased physician use of clinical practice guidelines (CPGs) and decision support tools (DSTs) without negatively impacting patient communication. This technology shows promise for improving care standards.

Area of Science:

  • Medical Informatics
  • Clinical Decision Support
  • Emergency Medicine

Background:

  • Clinical practice guidelines (CPGs) improve care but have low utilization.
  • Physician access to information at the point of care is crucial for guideline implementation.
  • Mobile computer (MC) technology offers potential for bedside access to clinical information.

Purpose of the Study:

  • To evaluate the impact of wirelessly networked mobile computers (MCs) on physician use of CPGs and decision support tools (DSTs) at the bedside.
  • To compare physician satisfaction and work patterns when using MCs versus standard desktop computers (DCs).

Main Methods:

  • A randomized controlled trial with a matched-pair design was conducted.
  • Ten emergency physicians completed five shifts using MCs and five shifts using DCs.

  • Data collected included end-of-shift questionnaires and CPG/DST usage logs.

    • Main Results:

    • Physicians rated MCs as convenient and nearly as fast as DCs.
    • MCs led to increased use of DSTs (p=0.03) and electronic CPGs (eCPG uses/shift, 3.6 vs. 2.0; p=0.033).
    • Efficiency was rated lower with MCs (p=0.02), but doctor-patient communication was unaffected (p=0.51).

    Conclusions:

    • Wireless MC technology facilitates bedside access to clinical information.
    • This technology enhances the utilization of CPGs and DSTs by physicians.
    • Further development of MC portability is needed to overcome limitations.
