We are doing a study to assess the impact of including patients in making decision regarding their own medical care in the emergency department. We will randomly assign them to either receive a decision aid or usual care. In doing this, we aim to increase patient satisfaction and safely decrease medical cost.

Further study details as provided by Mayo Clinic:

Primary Outcome Measures:
  • Patient knowledge [ Time Frame: Immediately after patient visit ] [ Designated as safety issue: No ]
    Patient knowledge regarding their short-term risk for an ACS and the risks of radiation exposure.

Secondary Outcome Measures:
  • Quality of decision making process [ Time Frame: Immediately after patient visit ] [ Designated as safety issue: No ]
    Quality of the decision making process for the patient and clinician

  • Satisfaction with decision aid [ Time Frame: Immediately after patient visit ] [ Designated as safety issue: No ]
    Patient and clinician acceptability and satisfaction with the decision aid

  • Proportion of patients who decided to undergo observation unit admission and urgent cardiac stress testing [ Time Frame: During the initial ED visit ] [ Designated as safety issue: No ]
    Proportion of patients who decided to undergo observation unit admission and urgent cardiac stress testing

  • Delayed or missed ACS [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
    Rate of delayed or missed ACS

  • Economic costs and healthcare utilization [ Time Frame: 30 days ] [ Designated as safety issue: No ]
    Economic costs and healthcare utilization
