• Medicare Advantage Part D plan• Why?

• More unit cost -> more opportunity• We think chronic disease management represents the

biggest opportunity to reduce cost of care by improving outcomes

• 7K enrollees in New Jersey (OPEN ENROLLMENT)• Clinical operations and customer service are in-house

• More on that later

Clover is a health insurance company

Our goal is to organize and leverage data to fix our healthcare system.

Clover is trying to improve health outcomes for our member population. We are using the tools of data science and modern web development to prioritize, assess and iterate upon our interventions.

Why did Clover build the data science function first?

Clinical Outcomes? So What?

There’s measuring clinical outcomes and then there is optimizing them.

To see what I mean let us imagine two campaigns around nurse visits.

Page 15: Building a Data Warehouse at Clover

Two Campaigns

Campaign Discharged Members

Clinical Effectiveness Coverage Control

Readmission Rate

Covered PopReadmissions

Uncovered Pop

Readmissions

A 100 .15 .4 .4 10 24

B 100 .2 .2 .4 4 32

Total readmissions in campaign A - 34Total readmissions in B – 36

So A is more effective at preventing readmissions, even though the intervention from B is the more clinically effective campaign

Things that can be affected… sometimes…maybe

Page 18: Building a Data Warehouse at Clover

So even when you know the outcomes

. . .you still can push to the optimal result by pushing up the processes that lead to the outcomes. If you want to talk about outcomes where the targeting is less obvious than a hospital discharge, then predictive modeling is more important.

What do you want to optimize outcomes then?• Flexible clinical operations team• Data warehouse full of joinable outcome and process

data• Apps that gather information as they enable operations• Speed – data speed and decision speed

Which brings us back to thisThis part is hard

This part is critical

Page 21: Building a Data Warehouse at Clover

Difficulties we faced, part I • Assembling catalogue of necessary

data

• Adding joinable keys into separate data sources

• Pinning down when membership starts and stops

• Parsing unstructured data

• Transforming hard to scrape-data (PDFs, invoices, one actual photograph of a series of data points)

• Interpreting claim duplications –

different for different files and different use cases

• Reconciling multiple sources of truth

• Understanding claim semantics

• PROVIDER DATA

• Interpreting part d accounting rules

• Counting hospital visits

• Automating all of the above

• Making sure that the automation doesn’t break any of the above

Difficulties we faced, part II A stylized representation of our call logs at one point.

Page 23: Building a Data Warehouse at Clover

An example – provider dataTo someone who has thought about it for a few minutes, provider data seems easy.

You want one row per provider with at least address, an identifier, name, specialty, and whether they are in network.

What happened?1. Our provider data migrated from Access to a more custom 🙀

physician data management solution.2. UI in new solution made it hard to validate data.3. Most accurate data ended up going onto paper. All sorts of horrible

consequences follow when the source of truth is paper 🙀🙀🙀

Page 24: Building a Data Warehouse at Clover

An example – provider data

What did we do?We took control of the data validation process. The object was to get provider data into a good state and be able to maintain and update it.

But provider data is bad because it is complex. You need to reconcile multiple sources of truth and update based on occasionally provisional data.

SIMPLIFIED WORKFLOW!!!

What have we built out of this?

• We can run all of the things you have to do – star ratings, finance, customer service, claim forensics out of our data warehouse.

• It can all be joined on a unique of a member, so everything can be related to everything else.

• We can run lots of things in SQL and Python cutting down on less automatable solutions like Excel and access.

• Speed and flexibility to answer any ad-hoc question quickly!

A working data warehouse!
