Chapter 8: Clinical Decision Support
Robert Hoyt MD
Harold Lehmann MD PhD
After reviewing these slides, the viewer should be able to:
Define electronic clinical decision support (CDS)
Enumerate the goals and potential benefits of CDS
Discuss the government and private organizations supporting CDS
Discuss CDS taxonomy, functionality and interoperability
List the challenges associated with CDS
Enumerate CDS implementation steps and lessons learned
Learning Objectives
Definition: “Clinical decision support (CDS) provides clinicians, staff, patients or other individuals with knowledge and person-specific information, intelligently filtered or presented at appropriate times, to enhance health and health care.” (ONC)
Keep in mind that any resource that aids in decision making should be considered CDS. We will only consider electronic CDS.
We define clinical decision support systems (CDSSs) as the technology that supports CDS
Introduction
Early on, CDS was thought of only in terms of reminders and alerts. Now we must include diagnostic help, cost reminders, calculators, etc.
In spite of the fact that we can use the Internet’s potent search engines to answer questions, many organizations promote CDS as a major strategy to improve patient safety
Most CDS strategies involve the 5 rights (next slide)
Introduction
The right information (what): should be based on the highest level of evidence possible and adequately referenced.
To the right person (who): the person who is making the clinical decision, the physician, the patient or some other team member
In the right format (how): should the information appear as part of an alert, reminder, infobutton or order set?
Through the right channel (where): should the information be available as an EHR alert, a text message, email alert, etc.?
At the right time (when) : new information, particularly in the format of an alert should appear early in the order entry process so clinicians are aware of an issue before they complete the task
Five Rights of CDS
As early as the 1950s scientists predicted computers would aid medical decision making
CDS programs appeared in the 1970s and were standalone programs that eventually became inactive
De Dombal’s system for acute abdominal pain: used Bayes theorem to suggest differential diagnoses
Internist-1: CDS program that used IF-THEN statements to predict diagnoses
Mycin: rule-based system to suggest diagnosis and treatment of infections
Historical perspective
DxPlain: 1984 program that used clinical findings to list possible diagnoses. Now a commercial product
QMR: began as Internist-1 for diagnoses and ended in 2001
HELP: began in the 1980s at the University of Utah that includes diagnostic advice, references and clinical practice guidelines
Iliad: diagnostic program, also developed by the University of Utah in the 1980s
Historical perspective
Isabel: commercial differential diagnosis tool wit.

MULTI-CRITERIA DECISION SUPPORT GUIDED BY CASE-BASED REASONINGcsandit
Many systems based on knowledge, especially expert systems for medical decision support have
been developed. Only systems are based on production rules, and cannot learn and evolve only
by updating them. In addition, taking into account several criteria induces an exorbitant number
of rules to be injected into the system. It becomes difficult to translate medical knowledge or a
support decision as a simple rule. Moreover, reasoning based on generic cases became classic
and can even reduce the range of possible solutions. To remedy that, we propose an approach
based on using a multi-criteria decision guided by a case-based reasoning (CBR) approach.
HEALTH PREDICTION ANALYSIS USING DATA MININGAshish Salve
Data mining techniques are used for a variety of applications. In healthcare industry, datamining plays an important
role in predicting diseases. For detecting a disease number of tests should be required from the patient. But using data
mining technique the number of tests can be reduced. This reduced test plays an important role in time and performance.
This report analyses data mining techniques which can be used for predicting different types of diseases. This report reviewed
the research papers which mainly concentrate on predicting various disease

INTEGRATING MACHINE LEARNING IN CLINICAL DECISION SUPPORT SYSTEMShiij
This review article examines the role of machine learning (ML) in enhancing Clinical Decision Support
Systems (CDSSs) within the modern healthcare landscape. Focusing on the integration of various ML
algorithms, such as regression, random forest, and neural networks, the review aims to showcase their
potential in advancing patient care. A rapid review methodology was utilized, involving a survey of recent
articles from PubMed and Google Scholar on ML applications in healthcare. Key findings include the
demonstration of ML's predictive power in patient outcomes, its ability to augment clinician knowledge,
and the effectiveness of ensemble algorithmic approaches. The review highlights specific applications of
diverse ML models, including moment kernel machines in predicting surgical outcomes, k-means clustering
in simplifying disease phenotypes, and extreme gradient boosting in estimating injury risk. Emphasizing
the potential of ML to tackle current healthcare challenges, the article highlights the critical role of ML in
evolving CDSSs for improved clinical decision-making and patient care. This comprehensive review also
addresses the challenges and limitations of integrating ML into healthcare systems, advocating for a
collaborative approach to refine these systems for safety, efficacy, and equity.

The purpose of this presentation is to describe step by step the transition of a SAS Programmer into a Clinical Statistical Programmer. It can be used as guidelines for SAS Programmers who wants to put their programming and technical expertise into industries.
A SAS Programmer is someone who uses SAS software for different scenarios. The person who uses it for different purposes is known as a SAS Programmer.
On the other hand, a Clinical Statistical Programmer performs all the procedures to generate future outputs and makes advanced and real-world developments to face further challenges. A primary role of Clinical Statistical Programmers is to use their technical and programming skills in order to enable clinical trial statisticians to perform their statistical analysis duties more efficiently.
This presentation will briefly discuss about the smooth transition that a SAS Programmer needs to go through in order to become a Clinical Statistical Programmer.

1. Jesus was both a person of his times and a figure whose teachings have obviously transcended his specific context. How did Jesus’s life and teachings better fit the first century? How do Jesus’s life and teachings seem to apply today? Which do you think better characterizes Jesus’s actual life and teachings? Is it more convincing to you that the first century Jesus resists our expectations, or that he anticipates them?
2. Jesus and the early Christians were a part of the larger Jewish context. At the same time, they also brought a number of innovations and new combinations. Compare Jesus’s life and message to that of the Pharisees, Essenes, followers of John the Baptist, Sadducees, priests, and/or the temple. How did Jesus and the early Christians fit with these other Jewish groups? How did they challenge them? Is it more convincing to you that Jesus and the early Christians were part of first century Judaism, or that they pushed to create a new religion?
3. Jesus avoided political attention for most of his life and work. Whatever he taught, he taught it skillfully and carefully enough that political figures allowed him to continue when many others were crucified. And yet, at the end, he too was crucified, but alone. Describe both the ways in which the historical Jesus avoided political confrontation and the ways in which he touched on politically sensitive ideas. Which gives us a better portrait of Jesus—the one who was politically cautious, or the rebel?

Chinese HistoryBased on the lecture on Chinese History and Marxi.docxspoonerneddy
Chinese History
Based on the lecture on Chinese History and Marxist Historiography that we can observe that women’s values for love and marriage have changed dramatically. China entered different periods from the feudal system to the opening of China. In the feudal period, people attached importance to family ethics took the land as the main interest and lived a life according to family rules. However, after China entered the capitalist era, capitalism encouraged people to pursue money and material life.
Marriage and love are very important to a woman. However, at different times, a woman has a completely different way of life. For example, Yulian lived in a feudal period dominated by family so she put her husband's family first. In my opinion, Yulian sacrificed her love and happiness for putting family first, which is a great thing but not worth it. However, Jia Jia from the beginning of the gold digger because of a series of events and become a brave pursuit of their own love and life woman is very worthy of praise.
With the passage of time, people's concept has changed gradually, from the old conservative value of family to the priority of their own ideas, from the pursuit of land as the interest standard to the pursuit of money and material life as the most important goal, which is an important symbol of the changing times.
Jia Jia and Julian have something in common. They all focus on who can give them a stable and good life. However, the difference is that Yulian follows the traditional idea of giving priority to her family but Jia Jia is based on their own ideas to live out their own life.
Marxist Historiography
1. Marxist Historiography has five different stages. The first stage is Primitive Communism, People at this stage use hunting as raw meat, which is the most important asset. The second stage is Oriental Slavery, the agricultural development began, and people willing to fight elsewhere and take slaves to cultivate for themselves. The most valuable is the slave. The third stage is Feudalism, serfs or peasants serve for their king and pay the rent or tax. Capitalism is the four-stage, the most important asset is money. The five-stage is Communism, for this stage that no more private ownership and it will be a world of peace and no war.
2. Base on Marxist Historiography lecture, the era of Yulian's life is very important to the family. She listens to her family's arrangements to get married and takes care of her husband's family after marriage. So I think Yulian is in the third stage of the Marxism Feudalism stage because people at this stage serve the king, they obedient and obey the rules. Yulian's life all follow her husband’s family and obey her family. Jia Jia emphasized that she has money from the beginning of the film. Anything she wants that she just use money to get it. All Jia Jia thinks that she can buy it with money. Therefore, Jia Jia is the fourth stage Capitalism stage in Marxism.
3. On the stage of Yulian so be .

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Harold Lehmann MD PhD
After reviewing these slides, the viewer should be able to:
Define electronic clinical decision support (CDS)
Enumerate the goals and potential benefits of CDS
Discuss the government and private organizations supporting
CDS
Discuss CDS taxonomy, functionality and interoperability
List the challenges associated with CDS
Enumerate CDS implementation steps and lessons learned
Learning Objectives
2. Definition: “Clinical decision support (CDS) provides
clinicians, staff, patients or other individuals with knowledge
and person-specific information, intelligently filtered or
presented at appropriate times, to enhance health and health
care.” (ONC)
Keep in mind that any resource that aids in decision making
should be considered CDS. We will only consider electronic
CDS.
We define clinical decision support systems (CDSSs) as the
technology that supports CDS
Introduction
Early on, CDS was thought of only in terms of reminders and
alerts. Now we must include diagnostic help, cost reminders,
calculators, etc.
In spite of the fact that we can use the Internet’s potent search
engines to answer questions, many organizations promote CDS
as a major strategy to improve patient safety
Most CDS strategies involve the 5 rights (next slide)
Introduction
3. The right information (what): should be based on the highest
level of evidence possible and adequately referenced.
To the right person (who): the person who is making the clinical
decision, the physician, the patient or some other team member
In the right format (how): should the information appear as part
of an alert, reminder, infobutton or order set?
Through the right channel (where): should the information be
available as an EHR alert, a text message, email alert, etc.?
At the right time (when) : new information, particularly in the
format of an alert should appear early in the order entry process
so clinicians are aware of an issue before they complete the task
Five Rights of CDS
As early as the 1950s scientists predicted computers would aid
medical decision making
CDS programs appeared in the 1970s and were standalone
programs that eventually became inactive
De Dombal’s system for acute abdominal pain: used Bayes
4. theorem to suggest differential diagnoses
Internist-1: CDS program that used IF-THEN statements to
predict diagnoses
Mycin: rule-based system to suggest diagnosis and treatment of
infections
Historical perspective
DxPlain: 1984 program that used clinical findings to list
possible diagnoses. Now a commercial product
QMR: began as Internist-1 for diagnoses and ended in 2001
HELP: began in the 1980s at the University of Utah that
includes diagnostic advice, references and clinical practice
guidelines
Iliad: diagnostic program, also developed by the University of
Utah in the 1980s
Historical perspective
Isabel: commercial differential diagnosis tool with information
5. inputted as free text for from the EHR. Inference engine uses
natural language processing and supported by 100,000
documents
SimulConsult: diagnostic program based on Bayes probabilities.
Predictions can also include clinical and genetic information
SnapDx: free mobile app that performs diagnostic CDS for
clinicians. It is based on positive and negative likelihood ratios
from medical literature. App covers about 50 common medical
scenarios

HIMSS: Their EMR Adoption Model rates EMRs from 0-7. Full
use of CDS qualifies as level 6
CMS: Meaningful Use, Stage 1 and 2 includes CDS measures
Supporting Organizations
8. Two phases of CDS: knowledge use and knowledge management
Knowledge Use. Involves these sequential steps:
Triggers are an event, such as an order for a medication >>
Input data refers to information within, for example the EHR,
that might include patient allergies >>
Interventions are the CDS actions such as displayed alerts >>
Action steps might be overriding the alert or canceling an order
for a drug to which the patient is allergic
CDS Methodology
Knowledge management involves:
Knowledge acquisition: acquire expert internal (EHR data) or
external data (e.g. Apache scores) for CDS
Knowledge representation. Use expert information, integrate it
with an inference engine and communicate it to the end user,
e.g. an alert (next slide)
Knowledge management (to follow)
CDS Methodology
9. Knowledge representation:
Configuration: knowledge is represented by choices made by the
institution
Table-based: rules are stored in tables, such that if a current
drug on a patient is in one row and an order for a second
inappropriate drug is stored in the same row, an alert is
triggered for the clinician
Rules based: knowledge base has IF-THEN statements; if the
patient is allergic to sulfa and sulfa is order then an alert is
triggered. Earlier CDS programs, such as Mycin, were rule
based
CDS Methodology
Knowledge representation (Cont.)
Bayesian networks: based on Bayes Theorem of conditional
probabilities it predicts future (posterior) probability based on
pre-test probability or prevalence. In spite of assuming that the
findings are supposed to be independent (such as signs and
symptoms), the Bayesian approach works very well and is
commonly employed in medicine. Formula is included below
CDS Methodology
10. The previous knowledge representation methods were based on
known data so they would be labelled “knowledge based CDS”.
If CDS is based on data mining-related techniques it would be
referred to as “non-knowledge based CDS”
Data mining (machine learning) algorithms have to be
developed and validated ahead of actual implementation. This
approach is divided into supervised and unsupervised learning
(next slide)
CDS Methodology
Supervised learning: assumes the user knows the categories of
data that exist, such as gender, diagnoses, age, etc. If the target
(outcome or dependent variable) is categorical (nominal, such
as lived or died) the approach will be called a classification
model. If the target is numerical (such as size of tumor, income,
etc.) the this is a regression model (see chapter on Introduction
11. to Data Science)
CDS Methodology
Supervised learning:
Neural networks: configured like a human neuron. The model is
trained until the desired target output is close to the desired
target. This is not intuitive and requires great expertise. See
figure to the right
CDS Methodology
Supervised learning:
Logistic regression: in spite of the name regression it is most
commonly used where the desired output/target is binary
(cancer recurrence, no cancer recurrence). Multiple predictors
are inputted, such as age, gender, family history, etc. and odds
ratios are generated. This is the gold standard for much of
predictive analytics
12. CDS Methodology
Decision trees: can perform classification or regression and are
the easiest to understand and visualize. Trees are used by both
statisticians and machine learning programs. Below is a contact
lens decision tree
CDS Methodology
Unsupervised learning: means data is analyzed without first
knowing the classes of data to look for new patterns of interest.
This has been hugely important in looking at genetic data sets.
Cluster analysis is one of the most common ways to analyze
large data sets for undiscovered trends. It is also more complex,
requiring more expertise
Association algorithms look for relationships of interest
CDS Methodology
13. Knowledge maintenance: means there is a need to constantly
update expert evidence based information. This task is difficult
and may fall to a CDS committee or technology vendor
CDS Methodology
CDS developers have struggled for a long time with how to
share knowledge representation with others or how to modify
rules locally. Standards were developed to try to overcome
these obstacles:
Arden syntax: represented by medical logic modules (MLMs)
that encode decision information. Ironically, the information
can’t be shared because institution specific coding resides
within curly braces { } in the MLM. This approach was doomed
and is known as the “curly brace problem”
CDS Standards
14. GELLO: can query EHRs for data to create decision criteria.
Part of HL7 v. 3
GEM: permits clinical practice guidelines to be shared in an
XML format, as an ASTM standard
GLIF: enables sharable and computable guidelines
CQL: draft HL7 standard to be used in XML format for
electronic clinical quality measures (eCQMs)
Infobuttons: can be placed in workflow where decisions are
made with recommendations
CDS Standards
Fast Healthcare Interoperability Resources (FHIR): developed
by HL7 there is great hope that this standard will solve many
interoperability issues.
It is a RESTful API (like Google uses) that uses either JSON or
XML for data representation
It is data and not document centric; so a clinician could place a
15. http request to retrieve just a lab value from EHR B, instead of
e.g. a CCDA. EHR can also request decision support from
software on a CDS server
Approximately, 95 resources have been developed to handle the
most common clinical data issues
CDS Standards
CDSSs can be classified in multiple ways:
Knowledge and non-knowledge based systems
Internal or external to the EHR
Activation before, during or after a patient encounter
Activated automatically or on demand
Alerts can be interruptive or non-interruptive
The next slides show a taxonomy based on CDS goals and
benefits mentioned earlier
CDS Functionality
CDS Functionality
16. CDS Functionality
(Function and Examples cont.)
Ordering facilitators:
Order sets are EHR templated commercial or home grown orders
that are modified to follow national practice guidelines. For
example, a patient with a suspected heart attack has orders that
automatically include aspirin, oxygen, EKG, etc.
Therapeutic support include commercial products such as
TheradocⓇ and calculators for a variety of medical conditions
CDS Functionality
17. Order facilitators (cont.)
Smart forms are templated forms, generally used for specific
conditions such as diabetes. They can include simple check the
boxes with evidence based recommendations
Alerts and reminders are the classic CDS output that usually
reminds clinicians about drug allergies, drug to drug
interactions and preventive medicine reminders. This is
discussed in more detail in the chapter on EHRs and the chapter
on patient safety
CDS Functionality
Relevant information displays
Infobuttons, hyperlinks, mouse overs: common methods to
connect to evidence based information
Diagnostic support: most diagnostic support is external and not
integrated with the EHR; such as SimulConsult
Dashboards: can also be patient, and not population level, so
they can summarize a patient’s status and thereby summarize
and inform the clinician about multiple patient aspects
CDS Functionality
18. Currently, there is no single method for CDS knowledge can be
universally shared. The approach has been to either use
standards to share the knowledge or use CDS on a shared
external server
Socratic Grid and OpenCDS are open source web services
platforms that support CDS
The FHIR standard appears to have the greatest chance for
success, but it is still early in the CDS game to know
CDS Sharing
CDS Implementation steps
19. CDS Implementation steps (cont.)
CDS Implementation steps (cont.)
General: exploding medical information that is complicated and
evolving. Tough to write rules
Organizational support: CDS must be supported by leadership,
IT and clinical staff. Currently, only large healthcare
organizations can create robust CDSSs
Lack of a clear business case: evidence shows CDS helps
improve processes but it is unclear if it affects behavior and
20. patient outcomes. Therefore, there may not be a strong business
case to invest in CDSSs
CDS Challenges
37
Unintended consequences: alert fatigue
Medico-legal: adhering to or defying alerts has legal
implications. Product liability for EHR vendors
Clinical: must fit clinician workflow and fit the 5 Rights
Technical: complex CDS requires an expert IT team
Lack of interoperability: must be solved for CDS to succeed
Long term CDS benefits: requires long term commitment and
proof of benefit to be durable
CDS Challenges
38
Lessons Learned
21. Lesson Learned (cont.)
This table came from multiple references found in the textbook
The future of Meaningful Use is unclear so there is no obvious
CDS business case for clinicians, hospitals and vendors
If the FHIR standard makes interoperability easier we may see
new CDS innovations and improved adoption
Future Trends
22. CDS could potentially assist with clinical decision making in
multiple areas
While there is widespread support for CDS, there are a
multitude of challenges
CDS is primarily achieved by larger healthcare systems
The evidence so far suggests that CDS improves patient
processes and to a lesser degree clinical outcomes

Patient Intake
• 44-year-old woman with a chief complaint of anxiety
Psychiatric History
• The patient had onset of anxiety and depression at about age
15, which
she began self-medicating with alcohol
• After graduating from high school, she began college and was
about to
leave for study abroad when she experienced a panic attack for
which
she was treated in the emergency room
• She was then hospitalized and treated for alcohol abuse at age
18,
and has remained sober ever since, although she does admit to
some
possible alprazolam (Xanax) abuse in 1999 as well as one
overdose
25. • Details of medication history unclear from available
information and
from patient’s memory, but has received numerous psychotropic
drugs
including antidepressants, antipsychotics, and mood stabilizers,
all
with poor results
• She was much better for several years following her ECT
treatment, but
had severe memory impairment
• She had a recurrence of her depression one year ago severe
enough
to become totally disabled, necessitating resignation from a job
as an
offi ce worker that she had enjoyed
• She continues to be disabled from depression and has a great
deal
of anxiety, subjectively more disturbed by her anxiety than by
her
depression
Social and Personal History
• Married since 1996 (second marriage); no children from either
marriage
• Non smoker
• Husband an architect, supportive
• Little contact with her family of origin
• Few friends or outside interests
Medical History
• Narcolepsy
27. 49
PATIENT FILE
• Gabapentin (Neurontin) 300 mg in the morning, 600 mg at
noon,
and 900 mg at night; occasional 100 mg as needed for
breakthrough
anxiety (experiences intolerable return of anxiety at much lower
doses)
• Pramipexole (Mirapex) 1 mg/night for restless legs syndrome
(unclear
whether helpful)
• Methylphenidate extended-release (Concerta) 54 mg/day for
daytime
sleepiness (thinks it is helpful)
• Sodium oxybate (Xyrem) 9 mg in one dose at night for
narcolepsy and
daytime sleepiness (not taken in recommended split dose)
• DDAVP (the peptide Desmopressin) 0.4 mg/night for
bedwetting
Based on just what you have been told so far about this
patient’s history
and current symptoms, would you consider her to fall within the
bipolar
spectrum?
• Yes
• No
Would you continue her “mood stabilizing” medications?
• Yes, continue both ziprasidone (Geodon) and lamotrigine
28. (Lamictal)
• Continue ziprasidone but discontinue lamotrigine
• Continue lamotrigine (Lamictal) but discontinue ziprasidone
(Geodon)
• No, discontinue both ziprasidone (Geodon) and lamotrigine
(Lamictal)
Attending Physician’s Mental Notes: Initial Psychiatric
Evaluation
• Nothing unexpected on mental status examination which
showed
depression and anxiety
• Because she has had numerous recurrences, this makes her
illness
appear to be somewhat unstable; however, she has not shown
any
overt signs of bipolarity
• The best diagnosis for this patient may be severe generalized
anxiety
with major depressive recurrent unipolar disorder
• Nevertheless, tactics that are useful for bipolar mood disorders
may
be useful in this patient
• Continuing ziprasidone (Geodon) and lamotrigine (Lamictal)
may help
mitigate the risk of a future relapse
• Thus, these medications were continued at the time of the
initial
evaluation
30. – During the past year she has also complained of restless legs
worse in the evening when trying to fall asleep
– Because of her diagnosis of narcolepsy, she was prescribed
methyphenidate extended release (Concerta) which helps a bit
for
her daytime sleepiness, but because she was still sleepy, sodium
oxybate (Xyrem) was added without further improvement of
daytime alertness although she gets to sleep right away and also
sleeps well through the night now
– In fact, she sleeps too well through the night now, and has
bed wetting, for which she has been prescribed DDAVP
(Desmopressin), but it is not very helpful
– Because of her diagnosis of restless legs syndrome, she is
prescribed pramipexole (Mirapex), with equivocal results
Based on what you know so far about this patient’s history,
current.
symptoms, and treatment responses, are you convinced her
daytime
sleepiness and nighttime restlessness are adequately diagnosed
and
treated?
• Yes
• No
Would you continue her 4 sleep disorder medications?
• Yes, continue all 4 (methylphenidate (Concerta), sodium
oxybate
(Xyrem), DDAVP (Desmopressin) and pramipexole (Mirapex))
• No, stop one or more of these
Downloaded from http://stahlonline.cambridge.org
32. • It is even possible that her sleep disorder treatments are
interfering
with her treatments for depression and anxiety
• Thus, her sodium oxybate (Xyrem) was tapered, and then her
DDAVP
(Desmopressin) discontinued, and her pramipexole (Mirapex)
was
also tapered over the next month following her initial
assessment
Case Outcome: First and Second Interim Followup Visits,
Weeks 2 and 4
• The patient experienced some initial insomnia and restless
sleep
as sodium oxybate (Xyrem) was withdrawn, but this resolved in
several days, as did her incontinence; her daytime sleepiness
actually
improved somewhat but she continued to have problems falling
asleep
some nights
• Next, her pramipexole (Mirapex) was tapered without
worsening of
restless legs, or of insomnia, or mood
• Finally, her daytime gabapentin (Neurontin) was tapered to
half
dose with improvement in daytime sleepiness, but this was only
intermittently tolerated, because of re-emergence of anxiety;
however,
higher gabapentin (Neurontin) doses caused daytime sleepiness
• She continued to have depression; also, her anxiety continued
34. she
sustained, but may benefi t from another alternative treatment
strategy
• Vagal nerve stimulation (VNS) (approved for treatment-
resistant
depression and available at the time of this evaluation)
– VNS involves surgical implant of a stimulation device in the
upper
left side of the chest (intended as a permanent implant, though
it
can be removed)
– The pulse generator can be programmed to deliver electrical
impulses to the vagus nerve at various durations, frequencies,
and
currents
– Stimulation typically lasts 30 seconds and occurs every fi ve
minutes
– After an initial wave of enthusiasm for this treatment, use of
VNS
for depression has waned due to disappointing results, high
costs and some complications, include the hassle of having the
stimulator and electrode removed
• Transcranial magnetic stimulation (TMS) (approved for
treatment-
resistant depression)
– Generally done on an outpatient basis
– Electromagnetic coil is placed against the scalp near the
forehead
36. – Stimulation is generally constant but can be temporarily
turned off
by holding a magnetic device over the area of the chest where
the
neurostimulator is located
– DBS is an experimental procedure available at only a few
medical
centers with research protocols that may cover some or all of
the
costs
– Risks and benefi ts of DBS remain unknown in treatment
resistant
depression, so DBS is reserved for patients who have failed
many
treatments, such as this patient
• After discussion of these options, the patient asked to defer
action on
them so she could research VNS, TMS and DBS, and in the
meantime,
she asked to try some other medications
Would you continue her methylphenidate extended release
(Concerta)
for daytime sleepiness?
• Yes
• No

PATIENT FILE
Attending Physician’s Mental Notes: Second Interim Followup,
Week 4, Continued
• Lithium
– Could help to boost her mood and mitigate risk of future
relapse
– If added it may not be necessary to give her a full dose as
she is
already on other mood stabilizing medications
• MAOI
– May help boost mood, as this has been effective for patients
with
anxious depression
– However, this could also be activating for some patients and
cause
problems with sleep and anxiety
– If added, an MAOI would require discontinuation of
bupropion
– Transdermal selegiline (Emsam) does not require dietary
restriction
and may be a preferable formulation
• Mirtazapine (Remeron)
– May boost mood and also potentially treat anxiety
• Quetiapine (Seroquel)
– May boost mood (approved for depressed phase of bipolar
disorder
39. and as adjunct for unipolar depression)
– May also be helpful for anxiety (anecdotal reports as adjunct)
– If added, it may require careful dosing to avoid daytime
sedation
• Aripiprazole (Abilify)
– May boost mood (approved as adjunct for unipolar
depression)
– Can be activating and cause problems with anxiety
• The patient was encouraged to switch from bupropion
(Wellbutrin)
to mirtazapine (Remeron), but instead opted for aripiprazole
(Abilify)
augmentation of her current medications (bupropion,
lamotrigine,
gabapentin, methylphenidate), while discontinuing ziprasidone.
Case Outcome: Multiple Interim Followups to Week 24
• Aripiprazole (Abilify) titration from 2 mg to 5 mg while
ziprasidone
(Geodon) was discontinued showed no real changes good or bad
for
the fi rst month (week 12)
• Aripiprazole was then increased to 10 mg, with slight
improvement
(week 16)
• After a second month at 10 mg of aripiprazole, no further
improvement in depression and anxiety and overall results not
satisfactory (week 20)
• The patient was switched from aripiprazole to quetiapine
(Seroquel),
which was not associated with improvement of mood or anxiety,

responsive
to the 8 medications she was taking on initial referral
(bupropion,
lamotrigine, ziprasidone, gabapentin, sodium oxybate, DDAVP,
methylphenidate and pramipexole)
• It seems possible that her sleep symptoms are more related to
her
anxious depression rather than to additional diagnoses of
narcolepsy
and restless legs syndrome and, in any event, her treatments for
these
sleep disorders did not improve her symptoms; discontinuation
of
several sleep medications (sodium oxybate, pramipaxole and
DDAVP)
if anything improved her symptoms; other clinicians may have
opted
to continue these medications
• Following simplifi cation of her medication regimen from 8
medications
to 5, she failed to respond to augmentation with aripiprazole or
with
quetiapine
• Possibly because of her prior response to ECT (and a fi rst

International Classifi cation Of Sleep Disorders
Diagnostic Criteria Of Narcolepsy
• Patient complains of excessive sleepiness or sudden muscle
weakness
• Recurrent daytime naps or lapses into sleep almost daily for at
least 3 months
• Possible sleep-onset REM (rapid eye movement) periods,
hypnagogic hallucinations, and sleep paralysis
• With cataplexy
• Sudden bilateral loss of postural muscle tone in association
with intense emotion
• Hypersomnia not better explained by another disorder
• Should be confi rmed by PSG (polysomnogram) followed by
MSLT (multiple sleep latency test, see below) which should
show
a mean sleep latency of 8 minutes and two more sleep-onset
REM periods (SOREMPs) following normal sleep
• May be confi rmed by orexin levels in the cerebrospinal fl uid
(CSF) <110 pg/ml or, 1/3 of mean normal control levels
Narcolepsy is estimated to occur in 0.03–0.16% of the general
population,
with its development mostly beginning in the teens. Narcoleptic
sleep
attacks usually occur for 10–20 minutes and, on awakening, the

Multiple Sleep Latency Test (MSLT)
• Dark comfortable room at an ambient temperature
• Smoking, stimulants and vigorous physical activity avoided
during the day, only light breakfast and lunch given
• Instructions are to
– “Lie quietly in comfy position, keep eyes closed, try to fall
asleep”
• Five nap opportunities as 2 hour intervals – initial nap
opportunity 1.5–3 hours after termination of usual sleep
• Between naps patient out of bed and awake
• Sleep onset determined by time from “lights out” to fi rst
epoch of
any sleep stage
• To assess occurrence of REM sleep the test continues for 15
minutes from fi rst sleep epoch
• Session terminated if sleep does not occur after 20 minutes
The Multiple Sleep Latency Test is carried out in sleep
laboratories often
after a night of PSG and a week fi lling in a sleep diary.

Cardinal diagnostic features of RLS (restless legs
syndrome)
1 Urge to move limbs usually associated with paresthesias or
dysesthesias
2 Symptoms start or become worse with rest
3 At least partial relief with physical activity
4 Worsening of symptoms in the evening or at night
Patients with RLS experience an urge to move their legs to rid
themselves
of unpleasant sensations (prickling, tingling, burning or
tickling;
numbness; “pins and needles’’ or cramp-like sensations). This
movement
typically relieves the sensations, which can occur at any time
but are
most disruptive when one is trying to fall asleep.

Chapter 7: Healthcare Data Analytics
Bill Hersh MD
53. After reviewing this presentation, viewers should be able to:
Discuss the difference between descriptive, predictive and
prescriptive analytics
Describe the characteristics of “Big Data”
Enumerate the necessary skills for a worker in the data analytics
field
List the limitations of healthcare data analytics
Discuss the critical role electronic health records play in
healthcare data analytics
Learning Objectives
One of the promises of the growing clinical data in electronic
54. health record (EHR) systems is secondary use (or re-use) of the
data for other purposes, such as quality improvement and
clinical research
Interest in healthcare data has grown exponentially due to EHR
incentives after the HITECH Act and the addition of genomic
information that will eventually be integrated with EHRs
Introduction
The term analytics is achieving wide use both in and out of
healthcare. A leader in the field defines analytics as “the
extensive use of data, statistical and quantitative analysis,
explanatory and predictive models, and fact-based management
to drive decisions and actions”
IBM defines analytics as “the systematic use of data and related
business insights developed through applied analytical
disciplines to drive fact-based decision making for planning,
management, measurement and learning
Introduction
55. Descriptive – standard types of reporting that describe current
situations and problems (how many uninsured patients do we
have with type 2 diabetes?)
Predictive – simulation and modeling techniques that identify
trends and portend outcomes of actions taken (can we predict
who will be readmitted for heart failure in the next 30 days?)
Prescriptive – optimizing clinical, financial, and other outcomes
(of those patients identified as high risk for readmission for
heart failure is it more cost effective to case manage in the
hospital or at home?)
Different Types of Analytics
Increasing functionality and value
Machine learning is the area of computer science that aims to
build systems and algorithms that learn from data
Data mining is defined as the processing and modeling of large
amounts of data to discover previously unknown patterns or
relationships
Text mining, a sub-area, applies data mining techniques to
mostly unstructured textual data
Analytics Concepts
56. Provenance, which is where the data originated and how
trustworthy it is for large-scale processing and analysis
Business intelligence, which in healthcare refers to the
“processes and technologies used to obtain timely, valuable
insights into business and clinical data”
Learning health system, where data can be used for continuous
learning to allow the healthcare system to better carry out
disease surveillance and response, targeting of healthcare
services, improving decision-making, managing misinformation,
reducing harm, avoiding costly errors, and advancing clinical
research
Analytics Concepts
Another related term is big data, which describes large and
ever-increasing volumes of data that adhere to the following
attributes:
Volume – ever-increasing amounts
Velocity – quickly generated
Variety – many different types
Veracity – from trustable sources
While big data is considered a buzz word by some, we are
57. having to deal with terabytes and petabytes of information
today. With the addition of genomics big data will escalate
Big Data
Healthcare organizations are generating an ever-increasing
amount of data. In all healthcare organizations, clinical data
takes a variety of forms, from structured (e.g., images, lab
results, etc.) to unstructured (e.g., textual notes including
clinical narratives, reports, and other types of documents)
For example, it was estimated by Kaiser-Permanente in 2013
that its current data store for its 9+ million members exceeds 30
petabytes (petabyte = 1024 terabytes) of data
Big Data
Another example is CancerLinQ that will provide a
comprehensive system for clinicians and researchers consisting
of EHR data collection, application of clinical decision support,
58. data mining and visualization, and quality feedback
Lastly, IBM’s Watson is now focusing on healthcare,
specifically Oncology so that massive amounts of cancer
information/research can be analyzed and applied to individual
patient decision making
Big Data
The Analytics Big Data Pipeline
According to Kumar et al
One begins with multiple data sources, that are extracted and
cleansed and normalized
Statistical processing prepares the data for output
Finally, the data helps generate descriptive, predictive and
prescriptive analytics
Accountable care organizations (ACOs) provide incentives to
deliver high-quality care in cost-efficient ways that will require
59. a robust IT architecture, health information exchange (HIE)
plus analytics. This approach would be used to predict and
quickly act on excess costs
As one pundit put it: ACOs = HIE + Analytics
Big Data
Big Data will Drive ACOs
Data generated in the routine care of patients may be limited in
its use for analytical purposes. For example, data may be
inaccurate or incomplete. It may be transformed in ways that
undermine its meaning (e.g., coding for billing priorities)
It may exhibit the well-known statistical phenomenon of
censoring, i.e., the first instance of disease in record may not be
when it was first manifested (left censoring) or the data source
may not cover a sufficiently long time interval (right censoring)
Challenges to Data Analytics
Data may also incompletely adhere to well-known standards,
60. which makes combining it from different sources more difficult
Clinical data mostly allows observational and not experimental
studies, thus raising issues of cause-and-effect of findings
discovered
Research questions asked of the data tend to be driven by what
can be answered, as opposed to prospective hypotheses
Challenges to Data Analytics
Data are not always as objective as one might like, and
“bigger” is not necessarily better
There are ethical concerns over how the data of individuals is
used, the means by which it is collected, and the possible divide
between those who have access to data and those who do not
Who owns the data and who can use it?
Challenges to Data Analytics
There is an emerging base of research that demonstrates how
61. data from operational clinical systems can be used to identify
critical situations or patients whose costs are outliers
There is less research, however, demonstrating how this data
can be put to use to actually improve clinical outcomes or
reduce costs. Studies using EHR data for clinical prediction
have been proliferating
Research and Application of Analytics
One common area of focus has been the use of data analytics to
identify patients at risk for hospital readmission within 30 days
of discharge. The importance of this factor comes from the US
Centers for Medicare and Medicaid Services (CMS)
Readmissions Reduction Program that penalizes hospitals for
excessive numbers of readmissions
This has led to research using EHR data to predict hospital
readmissions. Thus far, the results are mixed and several
examples of trials are included in the textbook chapter
Research and Application of Analytics
62. Research and Application of Analytics
Scenarios for EHR Data Analysis
Predicting 30-day risk of readmission and death among HIV-
infected inpatients
Identification of children with asthma
Risk-adjusting hospital mortality rates
Detecting postoperative complications
Measuring processes of care
Determining five-year life expectancy
Detecting potential delays in cancer diagnosis
Identifying patients with cirrhosis at high risk for readmission
Predicting out of intensive care unit cardiopulmonary arrest or
death
Identifying patients who might be eligible for participation in
clinical studies
Determining eligibility for clinical trials

Identifying Patients for Research Using EHR Data
63. Virtual Data Warehouse (VDW) Project was able to demonstrate
a link between childhood obesity and hyperglycemia in
pregnancy
United Kingdom General Practice Research Database
(UKGPRD), a repository of longitudinal records of general
practitioners, was able to demonstrate the ability to replicate the
findings of the Women’s Health Initiative and RCTs of other
cardiovascular diseases
Research and Application of Analytics
Use EHR Data to Replicate Randomized Controlled Trials
Other data repositories have helped to predict a variety of
cancers, risk for venous thromboembolism (blood clots) and
even rare medical disorders
Note the info box in the next slide that discusses data analytics
by the Veterans Health Administration (VHA)
Research and Application of Analytics
Use EHR Data to Replicate Randomized Controlled Trials
64. Case Study: Veterans Health Administration (VHA)
The VHA is a large healthcare system with a long track record
of EHR use (VistA). In 2013, the VHA had 30 million unique
electronic patient records with 2 billion clinical notes (100,000
notes added daily). They also have had a corporate data
warehouse (CDW) of structured data which allows them to
analyze clinical and administrative data for patients at risk of
hospital admission (from falls, coronary disease, PTSD, etc.).
Analytics are run once weekly on all primary care patients
looking for “at risk” patients who would likely require more
coordinated care using care managers, home health and
telehealth. In 2012, VHA researchers reported in the American
Journal of Cardiology on the use of predictive analytics on heart
failure patients. Specifically, using six categories of risk
factors derived from the EHR they could successfully predict
which patients were at risk of hospitalization and death.
According to Dr. Stephen Fihn, Director of Analytics and
Business Intelligence for the VHA, the VHA is embarking on a
24-month pilot project to expand the use of healthcare data
analytics. They will use natural language processing and
machine learning to analyze patient records to aid in diagnosis,
identify dangerous drug-drug interactions and optimally design
treatment strategies.
65. Research and Application of Analytics
Using Genomic Information and EHRs
Researchers have carried out genome-wide association studies
(GWAS) that associate specific findings from the EHR (the
“phenotype”) with the growing amount of genomic and related
data (the “genotype”) in the Electronic Medical Records and
Genomics (eMERGE) Network
eMERGE has demonstrated the ability to identify genomic
variants associated with atrioventricular conduction
abnormalities, red blood cell traits, white blood cell count
abnormalities, and thyroid disorders
More recent work has “inverted” the paradigm to carry out
phenome-wide association studies (PheWAS) that associated
multiple phenotypes with varying genotypes
66. Genome-wide and phenome-wide association studies are also
discussed in the chapter on bioinformatics
Research and Application of Analytics
Using Genomic Information and EHRs
There has been little focus on the human experts who will carry
out analytics, to say nothing of those who will support their
efforts in building systems to capture data, put it into usable
form, and apply the results of analysis
Where will these workers come from and what will be the
education of those who work in this emerging area, that some
call data science?
We do know that data analytics experts are in high demand
Role of Informaticians in Analytics
From basic biomedical scientists to clinicians and public health
workers, those who are researchers and practitioners are
drowning in data, needing tools and techniques to allow its use
67. in meaningful and actionable ways
Dr. Hersh believes that a strong background in Health
Informatics or Biomedical Informatics is the best preparation
for the healthcare data analytics field
Role of Informaticians in Analytics
Data science is more than statistics or computer science applied
in a specific subject domain. It requires an understanding of
data, its varying types, and how to manipulate and leverage it
The field requires skills in machine learning, a strong
foundation in statistics (especially Bayesian), computer science
(representation and manipulation of data), and knowledge of
correlation and causation (modeling)
Role of Informaticians in Analytics
A report by McKinsey consulting states that there will soon be a
need in the US for 140,000-190,000 individuals who have “deep
68. analytical talent” and an additional 1.5 million “data-savvy
managers needed to take full advantage of big data”
An analysis by SAS estimated that by 2018, there will be over
6400 organizations that will hire 100 or more analytics staff
Another report found that data scientists currently comprise less
than 1% of all big data positions, with more common job roles
consisting of developers (42% of advertised positions),
architects (10%), analysts (8%) and administrators (6%)
The Need for Data Analytics Experts
The technical skills most commonly required for big data
positions as a whole were NoSQL, Oracle, Java and SQL
PriceWaterhouseCoopers noted that healthcare organizations
need to acquire talent in systems and data integration, data
statistics and analytics, technology and architecture support,
and clinical informatics
Business knowledge is also useful
The Need for Data Analytics Experts
69. Programming - especially with data-oriented tools, such as SQL
and statistical programming languages
Statistics - working knowledge to apply tools and techniques
Domain knowledge - depending on one's area of work,
bioscience or health care
Communication - being able to understand needs of people and
organizations and articulate results back to them
The Need for Data Analytics Experts
What Skill Sets Should Universities Train For?
Healthcare data has proliferated greatly, in large part due to the
accelerated adoption of EHRs
Analytic platforms will examine data from multiple sources,
such as clinical records, genomic data, financial systems, and
administrative systems
Analytics is necessary to transform data to information and
knowledge
Accountable care organizations and other new models of
healthcare delivery will rely heavily on analytics to analyze
financial and clinical data
There is a great demand for skilled data analysts in healthcare;
expertise in informatics will be important for such individuals
Conclusions
