“Welcome. Table for one?”
A modern data ecosystem should leverage the core similarities
between - Disease registries
- Observational studies - Population health analysis

Precision Medicine and Population Health
• Registries and observational data are the current workhorses of population health, patient-centered, and translational research
• Population Health Management plans have the potential to facilitate even broader & better integrated research
• None of these 3 approaches is currently where they should be https://cancercontrol.cancer.gov/research-emphasis/precision-medicine.html

Two Primary Use Cases for Epidemiologists
Data Exploration • How many …
– Of a type of cancer? – Biospecimens? – Cancers with biospecimens? – Responded to the questions
about …?
• Goal: inform feasibility – Exemplifies many disease-
registry use cases – Patient matching for trials
Data Analysis • Enable statistical analyses
– Cohort selection – Include/exclude criteria &
follow-up time – Choose covariates – Univariate & multivariate
• Goal: discover & publish – Analytic methods for disease
endpoints are similar to methods for population-health endpoints, e.g., cost

Strengths of CTS DW Environment
Data Exploration • Provide value by …
– Replacing code with clicks – Displaying related results
right away, instead of requiring users to ask for the same data every time
• Goal: enable better, faster, deeper decision-making about feasibility
Data Analysis • Enable statistical analyses
– Cohort selection – Include/exclude criteria &
follow-up time – Choose covariates – Univariate & multivariate
• Goal: discover & publish – Analytic methods for disease
endpoints are similar to methods for population-health endpoints, e.g., cost

Data Analysis: Add Structure and Process
• Before: “Email the PI …” – Email is not a process
• Instead, standardize the way users define & request data
Framework • Timeline, type of analysis, number of outcomes
Cancer • Codes/site, Incident/prevalent/fatal, Dx date, censoring
Mortality • Cause of death; previous diagnoses
Hospitalization • ICD code(s), Incident/prevalent, 1st/2nd, Dx date
Survey data • Which survey / sections / questions

What We Do With that Information
• Epidemiology lives in a desktop SAS world …
Insert choices into SAS PROC SQL template
Identifies data to call from DM
Give users shared workspace: • Tableau workbook • 1-line SAS include code template

Not So Fast …
It only takes 10 minutes of direct observation of a nurse in a hospital to understand care-delivery processes are not standardized and are dependent on individuals, not systems. This lack of reproducibility leads to errors. Since every caregiver does it his or her own way, it’s difficult to improve anything. Stable systems that are reproducible are required to deliver consistently high quality. Industrial companies figured this out 50 years ago. What that nurse and doctor do and how they do it are still what will determine successful outcomes of care. Every nurse and doctor does not get to do it his or her own way. Standards are established about how the work is performed, and those standards are followed by all until a better way is determined collectively by the team.

A Counterclockwise CTS Journey, From the Bottom Up

Where is the Boundary Between Exploration & Analysis?
Open-Ended Exploration
Traditional Analysis
Increasing #s of queries & slice-and-dice strain exploration & visualization tools
Example 1: calculate power
• All-cause mortality endpoint • Multiple questionnaire variables • Within Tableau, connect 26,000 deaths to
all 5122 questionnaire variables to enable picklist that updates distributions
Example 2: focused analytic subgroup
• Identify all participants who completed Q5 & donated blood & were cancer-free & donated blood +/- 1 year of Q5 and answered specific questions in Q5
• Ask user to request analytic data

Next Steps for the CTS
• 5-year project funded by U01-CA199277, Sep. 2015 to Aug. 2020 – Continue to build library of analytic & exploration tools
• Every new project helps to fill the shelves with reusable templates – Build out domain-specific visualizations to drive insights
• Cancers, hospitalizations, questionnaire, biospecimens
• Ultimate goals: – Deliver analytic results at the time users define their data requests
• A priori defined analysis plan should be a script that runs at selection – Utilize the Calif. Teachers Study to develop, test, & harden
observational data in the NCI Data Commons and Data Ecosystem • All CTS data should be publicly available for individual-level analysis • Need to address data processes, but lots of lessons learned to date
![Page 34: NEXT-GENERATION DISEASE REGISTRIES AND POPULATION … CI4CC April 2018.pdf · NEXT-GENERATION DISEASE REGISTRIES AND POPULATION HEALTH INFORMATICS INITIATIVES, WITH A FOCUS ON REAL-WORLD](https://reader034.vdocuments.us/reader034/viewer/2022042316/5f0473917e708231d40e089a/html5/thumbnails/34.jpg)

• Observational data and disease registries are likely to be rate-limiting steps in achieving a fully integrated Cancer Data Ecosystem – Less big data means less recognition of need for & urgency to change – More process problems means a bigger workflow challenge
• And greater need to accelerate adoption of automated analytics
• Leveraging the pipelines and analytic workflows from the NCI GDC and genomics clouds could accelerate the integration of registry, observational study, and population-based data
• Essential to bend the cost curve – Less data management and analysis, and more results interpretation
