Problem 1: Medication related Care Coordination
• Care delivery process & patient sentiment
• Using unstructured data (text) analysis to uncover patient
sentiment as it related to pain medication management
• Text analysis reveals underlying care process
• Care delivery process innovation of developing a
“discharge triage” to facilitate care coordination between
hospital and home

Patient Pain-Medication Management

Patient Comments
Communication
(Physician, Nurse,
Administration/St
aff)
I had poor pain control immediately post-op, despite the fact
that I repeatedly told the nurses that I had my pain meds
(prescribed by my doctor of 8 1/2 yrs.) with me. I was in
severe pain for a day and a 1/2.
Treatment
Protocol
…..Two different nurses tried to give me a pain med I was
allergic too.
Personnel (Nurse) The only bad experience I had was when trying to get my pain
medication administered.
Care Process
(transition)
I felt that I was sent home w/improper pain management
medications.
Was sent home w/weak pain meds (4 day supply). I was still in
bad pain 8 days later.

Problem 2: Clinical Decision Support for Kidney
Allocation in the context of Constrained Supply

Predicting the outcome for a
hypothetical patient • The patient is 62 years old with a BMI of 20 (lower due to
illness)
• The recipient is diabetic and currently treatment for
hypertension. The recipient is also hepatitis-C positive
with a creatinine of 4, serum albumin of 1.8, and MELF of
40 reflecting liver disease
• The donor is a 35 year old diseased individual who had a
BMI of 40 (assuming a diseased-donor kidney
transplantation)
Predicting the outcome for a
hypothetical patient
SKLT Scenario (kaltyn=0)
Predicting the outcome for a
hypothetical patient
KALT Scenario (kaltyn=1)
Results
• This study developed a NN model to predict the outcomes
in dual organ (Kidney-Liver) transplant patients
• The model predicted outcome for a hypothetical patient
found that the recipient would have a lower likelihood of
death with KALT while having a higher likelihood of being
alive with a successful transplantation with SKLT
• Appropriate predictive models like those developed in this
study may be used to create individual/clinical decision
support solutions, to help physicians addressing the organ
allocation problem in an environment of significantly
constrained supply
Problem 3: Improving COPD Readmission
Prediction • High levels of avoidable hospital readmissions of patients
with Chronic Obstructive Pulmonary Disease (COPD) is a
significant challenge
• Patient data include significant amount of unstructured
data, such as physician’s notes and patient discharge
summaries
• Accuracy of models to predict the risk of readmission can
be improved using such data by developing a natural
language processing based approach to extract such
information from patient records
• But this is not a simple task due to the ambiguity and
variety of language used in the description and evaluation
of any specific patient condition

NLP Extraction Results (N=1695 over 18 months)
Results
• This study developed a component-based domain-
independent text analysis system for processing of the
natural language known as Domain-independent Natural
Language Processing System (DINLP)
• It was effectively applied to Chronic Obstructive
Pulmonary Disease (COPD) patient data in the context of
hospital readmission
• Continuing research in this domain extends to integrating
DINLP with other machine learning modeling approaches
Conclusion
• Advanced data analytics provides opportunities for
innovations in patient care
• These methods can be applied to other complex services
• I would like to thank my co-authors in the various studies
