ClinicalVis is a medical record visualization that attempts to improve upon the baseline table-based medical record visualizations.

See the paper that describes and evaluates the visualization on arxiv.

This project contains two Polymer elements:

• clinical-vis: The updated medical record visualization
• clinical-table: A baseline table-based medical record visualization

First, make sure you have the Polymer CLI installed. Then run polymer serve to serve your element locally.

From this top-level clinical-vis directory:

$ polymer install
$ polymer serve

Then navigate to:

• http://localhost:8081/components/clinical-vis/demo/index.html for a demo of the clinical-vis visualization
• http://localhost:8081/components/clinical-vis/demo/table-index.html for a demo of the baseline clinical-table visualization

Each of the elements exposes a single bound parameter, 'json', which should be set to a JSON object containing the patient record to visualize. This is the expected format of the JSON object:

Top level key-value pairs:

• 'diagnosis': (string) Admitting diagnosis
• 'dob': (string) Date of birth (YYYY-MM-DD)
• 'ethnicity': (string) Ethnicity
• 'gender': (string) Gender
• 'icu_type': (string) ICU type
• 'notes': (array) List of notes in the medical record, see below.
• 'events': (array) List of events in the medical record, see below.

Each note in the 'notes' field is an object with the following key-value pairs:

• 'timestamp': (string) Number of seconds since UNIX epoch when the note was taken
• 'category': (string) Category of the note, such as "Nursing" or "Radiology"
• 'note': (string) Text of the note.

Each event in the 'events' field is an object describing a measured or observed value with the following key-value pairs:

• 'timestamp': (string) Number of seconds since UNIX epoch when the event was recorded
• 'key': (string) Name of the event, such as 'Temperature' or 'Heart Rate'
• 'category': (string) The category of the event, such as 'Vitals' or 'Labs'
• 'value_string': (string) If the event data is a string, such as the the value 'Clear' for the category 'Lung Sounds', then this field holds the value.
• 'value_num': (number) If the event data is a number, such as the the value 165 for the category 'Platelets', then this field holds the value.
