Fresenius Chairside – world’s largest healthcare deployment
up to 100k Tx/day
8 Timezones

6.
FOR INTERNAL PURPOSES ONLY.
Chairside application – goal of moving 70 million patient treatment documents
from Oracle to MongoDB
via the Treatment Sheet App for CS 2x and 1x treatments
minimizing the Operational DB to handle 60 days of data only in Oracle DB
Current Challenges Desired Outcomes
Large anticipated growth from 2015-
2020
 Easily scalable applications
Long dev cycles  Fast, iterative dev cycles
Can’t incorporate diverse data, new
sources coming in from acquisitions
 Easy to incorporate any data
High DB spend  Lower TCO
Must meet PHI requirements for
HIPPA
 Compliance
Single View - 1st MongoDB project at Fresenius 2013-2014

7.
FOR INTERNAL PURPOSES ONLY.
Ideal when reads >> writes – retrieve entire document
with one read, no joins
Agility and flexibility
Data model supports business change
Rapidly iterate to meet new requirements
Intuitive, natural data representation
Eliminates ORM layer
Developers are more productive
Reduces the need for joins, disk seeks
Programming is more simple
Performance delivered at scale

Single View - MongoDB as perfect companion to a Document Model App

Single View – began with ‘Create a searchable treatment record archive’
• Opportunity
• Evaluation

Patient Portal – goal of supporting 20,000 home patients
Making self treatment and self charting at home a possibility With Zero downtime
Current Challenges Desired Outcomes
Several data sources and systems are
involved in the home or in clinic
dialysis

Use an event driven architecture to
create a real time synchronization of all
workflows involved in home or in clinic
treatment
Systems have downtime at night or on
weekends
 Provide a zero downtime environment
No current write capability into some
systems, or slower, batch mode
capability into some other systems

Allow patients/clinicians to write and read
data from systems in real time
Single View leads the way to the Operational Data Store 2015-2017
Care Coordination – goal of supporting 40,000 clinicians coordinate care for
300,000 patients
Making self treatment and self charting at home a possibility With Zero downtime
