Rapid Analysis

  1. Information on this section will be posted by April 9th.

Optional Rapid Analysis

Make a narrated Power Point slides regarding what you have learned about the evidence on impact of EHR on efficiency and quality of care. Video

Please do not provide opinions but review the evidence presented to you in the above readings.  Prepare your slides as if you are reporting to the CEO of a hospital or clinic thinking through whether they should purchase an EHR.

  1. Be brief:  Do not exceed 10 slides or 10 minutes of narration.
  2. Cite your work in smaller font on each slide so I can trace your arguments to its source.  Do not present opinions but data.
  3. Be clear.  Do not extrapolate from studies done in a clinic to studies in hospitals and vice versa.
  4. Be organized.  Give an overview of what you are going to talk about, present your points and make a summary at the end. 
  5. Be visual.  Use charts and graphs from your reading and cite your work.

This work can be accomplished with help from a colleague.  Please do not work with the same colleague that you have worked in a previous project.  Once done, post your work on a public web and send the URL to the instructor or provide your work on a compact disk to the instructor.
