EHR Design Talk with Dr. Rick 12/3/12

The Snapshot-in-Time Design

There are two basic EHR designs for presenting the patient information that accumulates over time (see my last post).

By far, the most common EHR design solution is to display a summary screen of the patient’s current health information, organized by category (Problem List, Past Medical History, Medications, and so forth). Past information is available in date-sorted lists or indicated by start and stop dates.

The other design solution is to display a series of snapshots that capture the state of the patient’s health at successive points in time. While this design was at the core of paper-based charting (see Why T-Sheets Work), it is an uncommon EHR design.

In my opinion, the snapshot-in-time design has three advantages:

The following EHR screen mockups display a patient’s story as snapshots in time. While these illustrations are for an ambulatory EHR, the design works equally well for hospital-based systems.

To see the mockups, click on the PowerPoint link below. Once PowerPoint is open, expand the view by clicking on the full screen button in the lower right corner (indicated by arrow).
