Mobile Home Screens

Mobile Home Screens

Better Home Screen?

Definitely without iPhone’ish glossy icons,
wasting potentially useful space around.
Want it or not, but glossy must stay in the past.
Near future is flat.

With aligned multi-sized widgets like Winphone.
With variety of widgets like Android.
But much more aesthetic than they are today!

With more information embedded into the icon-sized area,
like Facebook Home, three faces into small context area.
Ideally the home screen can delivery useful information in five-six different contexts even without any clicks on them.

Smaller widgets will remain and prevail,
because they are sized to our finger…

Mobile EMR, Part IV

This is continuation of Mobile EMR, Part III.

It happened to be possible to fit more information to the single pager! We’ve extended EKG slightly, reworked LABs results, reworked measurements (charts) and inserted a genogram. Probably the genogram brings majority of new information in comparison to other updates.

v4 of mEMR concept

Right now the concept of mobile EMR looks this way…

New ‘All Data’ charts

Initially the charts of measured values have been from dots. Recent analysis and reviews tended to connect the dots, but things are not so straightforward… There could be kind of sparkline for the current period (7-10 days). Applicability of sparkline technique to represent data from the entire last year is suspicious. Furthermore, if more data is available from the past, then it will be a mess rather than a visualization, because there is so narrow space allocated for old data. Sure, the section of the chart could be wider, but does it worth it?

What is most informative from the past periods? Anomalies, such as low and high values, especially in comparison with current values. Hence we’ve left old data as dots, previous year data as dots, and made current short period as line chart. We’ve added min/max points to ease the analysis of the data for MD.

Genogram

Having genogram on the default screen seems very useful. User testing needed to test the concept on real genograms, to check the sizes of genograms used most frequently. Anyhow, it is always possible to show part of the genogram as expanded diagram, while keep some parts collapsed. The genogram could be interactive. When MD clicks on it, she gets to the new screen totally devoted to the genogram with all detailed attributes present. Editing could be possible too. While default screen should represent such view onto the genogram that relates to the current or potential diagnosis the patient has.

In the future the space allocated for the genogram could be increased, based on the speed of evolution of genetic-based treatments. May be visualization of personal genotyping will be put onto the home screen very soon. There are companies providing such service and keeping such data (e.g. 23andme). Eventually all electronic data will be integrated, hence MDs will be able to see patients genotyped data from EMR app on the tablet.

DNA Sequence

This is mid term future. DNA sequencing is still a long process today. But we’ve got the technology how to deliver DNA sequence information onto the tablet. The technology is similar to BigImage(tm). Predefined levels of information deliver could be defined, such as genes, exoms and finally entire genotype. For sure additional layers overlays will be needed to simplify visual perception and navigation thru the genetic information. So technology should be advanced with that respect.

Mobile EMR, Part II

On 27th of August I’ve published Mobile EMR, Part I. This post is a continuation.

The main output from initial implementation was feedback from users. They just needed even more information. We initially considered mEMR and All Information vs. Big Data. But it happened that some important information was missing from the concept relied on Powsner/Tufte research. Hence we have added more information and now ready to show the results of our research.

First of all, data is still slightly out of sync, so please be tolerant. It is mechanical piece of work and will be resolved as soon as we integrate with hospital’s backend. The charts on the default screen will show the data most suitable for the each diagnosis. This will be covered in Part III when we are ready with data.

Second, quick introduction for redesign of the initial concept. Vital Signs had to go together, because they deliver synergetically more information when seen relatively to each other. Vital Signs are required for all diagnosis. Hence we have designed a special kind of chart for vital signs and hosted it on top of the iPad. Medications happened to be extremely important, so that physician instantly see what meds are used right now, reaction of vital signs, diagnosis and allergy, and significant events. All other charts are specific to the diagnosis and physician should be able to drag’n’drop them as she needs. It is obvious that diabetes is cured differently than Alzheimer. Only one chart has its dedicated place there – EKG. Partially, EKG is connected to the vital signs, but historically (and technically too) the EKG chart is complemently different and should be rendered separately. Below is a snapshot of the new default screen:

Default Screen (with Notes)

Most important notes are filtered as Significant Events and could be viewed exclusively. Actually default screen can start with Significant Events. We just don’t have much data for today’s demo. Below is a screenshot with Significant Events for the same patient.

Default Screen (with Significant Events)

Charts are configurable like apps on iPad. You tap and hold the one, then move to the desired place and release it. All other charts are ordered automatically around it. This is very useful for the physician to work as she prefers. It’s a good opportunity to configure the sets according to diagnosis. Actually we embedded pre-sets, because it is obvious that hypertension disease is cured differently than cut wound. Screenshot below shows some basic charts, but we are working on its usability. More about that in Part III some time.

Charts Configuration

According to Inverted Pyramid , default screen is a cap of the information mountain. When many are hyping around Big Data, we move forward with All Information. Data is a low-level atoms. Users need information from the data. Our mEMR default screen delivers much information. It can deliver all information. It is up to MD to configure the charts that are most informative in her context. MD can dig for additional information on demand. Labs are available on separate view, groupped into the panels. Images (x-rays) are available on separate view too. MD can click onto the tab IMAGERY and switch to the view with image thumbnails, which correspond to MRIs, radiology/x-ray and other types of medical imagery. Clicking on any thumbnail leads to the image zoomed to the entire iPad screen estate. The image becomes zoomable and draggable. We use our BigImage(tm) IP to empower image delivery of any size to any front end. The interaction with the image is according to Apple HIG standard.

Imagery (empowered by BigImage)

I don’t put here a snapshot of the scan. because it looks like standard full screen picture. Additional description and demo of the BigImage(tm) technology is available at SoftServe site http://bigimage.softserveinc.com. If new labs or new PACS are available, then they are pushed to the home screen as red notifications on the tab label (like on MEASUREMENTS tab above) so that physician can notice and click to see them. It is common scenario if some complicated lab required, e.g. tissue research for cancer.

Labs are shown in tabular form. This was confirmed by user testing. We have grouped the labs by the corresponding panels (logical sets of measurements). It is possible to order labs by date in ascending (chronological) and descending (most recent result is first) orders. Snapshot below shows labs in chronological order. Physician can swipe the table to the left (and then right) to see older results.

Labs

Editing is possible via long tap of the widget, until corresponding widget goes into the edit mode. Quick single click will return the widget to preview mode. MD can edit (edit existing, delete existing and assign new) medications, enter significant sign, notes. Audit is automatic, according to HIPAA, time and identity is captured and stored together with edited data.
