3. Poll: Getting to know you
1. What do you do?
2. Are you using a data-driven approach to
reducing readmissions today?

4. Why we are here today – Reducing Hospital Readmissions
TheProblem
Patient care requires
innovative methods
to address the
complexity for
improving
outcomes
Readmission rates
exceed 17% and
most of these are
avoidable
Medicare spends
$17B for avoidable
readmissions
CurrentSituation
Hospitals have started
to use analytics such
as the LACE index to
decrease readmission
rates
The Readmission
Reduction Program
(HRRP) reduces
payments up to 3%
for hospitals with
excess readmissions
for specific diagnoses
NeedforReal-timeInsight
Most analytic tools
are not specific and
do not leverage the
wealth of data stored
in EMRs, including
text, numeric, and
image data.
Predictive risk scoring
need to be
explainable to all
healthcare
professionals

5. Methods for Understanding Readmission Risk
Difficulty of Implementation
Precision
Intuition
• Health care professionals are experts
who understand emergent
phenomena
• Like all humans, prone to blind spots
Analytic
Approach
• Rules based
approaches provide
recommendations
on data
• They do not provide
actionable insights
Machine
Learning
• Can learn from highly complex data
and self organize to understand risk
• Provides real-time feedback to
healthcare professionals
• Analyzes the efficacy of proactive
measures

6. Precise, Data Driven Healthcare Requires Machine Learning
• Data Quality Analysis
• Precision Medicine
• Radiology Image Analysis
• Fraud, Waste, and Abuse
• Connected Devices
• Clinical Decision Support

13. Poll: Data Science at your workplace
1. Does your team have data scientists or
software developers?
2. Are you using Machine Learning in
production today?

14. Readmission Scoring: Machine Learning Process
Supervised Machine Learning workflow:
Historical
Data
• Split train/test
datasets
• Readmissions&
non-
readmissions
Train ML
Model
• Use the
medical history
of patients
• Use interaction
of patients
Deploy
• Predict
likelihood to
be readmitted
to hospital
