Topics
•Communication in ICU
•ABCDE Protocol
•ICU Data Collection
•Infection Control in ICU
ICU:
“The Ineffective
Communication Unit”
•One day cross-sectional study of ICU clinicians
•Conflicts perceived by 72% of respondents
•Physician-nurse conflict most common at 32%.
•Most common conflict causing behaviors
– Personal animosity
– Mistrust
– Communication gaps
Azoulay AJRCCM 2009
Interdisciplinary Communication in ICU
•Bad Communication associated with:
– Job dissatisfaction
– Burnout
– Misperception of patient care goals
– Medical errors
•Tools to improve interdisciplinary communication in
ICU
– Creating safe atmosphere to speak up
– Willingness to listen
– Leveling Hierarchy (Interdisciplinary rounds)
Role of the MICU Fellow in Promoting
Good ICU Communication
•At center of daily activities of ICU
•Can foster good communication between
disciplines
•Often aware conflicts first.
•Set an example for the residents

A Multidisciplinary Approach to the
Mechanically Ventilated Patient:
The ABCDE Bundle
Changing Paradigm of ICU Care
When I was resident
Now
Why an Integrated approach?
We Need Coordinated Care
• Many tasks and demands on critical care staff
• About aligning the people, processes, and
technology already existing in ICUs
• ABCDE bundle is interdisciplinary, and designed to:
•Improve collaboration among clinical team members
•Standardize care processes
•Break the cycle of oversedation and prolonged
ventilation
What are the components of the
ABCDE Bundle?
AB
Awakening and Breathing Coordination
C
Choice of Analgesics and Sedatives
D
Delirium Identification and Management
E
Early Exercise and Mobility
Daily Awakening Trials
Why Is Interruption of Sedation Effective?
•Less accumulation of sedative drug and
metabolites
•Less sedative medication used overall
•Opportunity for more effective weaning from
mechanical ventilation
Sessler CN. Crit Care Med 2004
Kress et al. NEJM. 2000
Results
•Shorter duration of
mechanical ventilation
•Shorter ICU LOS
•Fewer tests for altered
mental status
Kress et al. N Engl J Med 2000; 342:1471-7
“SAT + SBT” Was Superior to
Conventional Sedation + SBT
Extubated faster
Discharged from ICU sooner

•Anxiety
•Pain
•Patient-ventilator
dyssynchrony
•Agitation
– Self-removal of
tubes/catheters
•Care provider assault
•Myocardial ischemia
•Family dissatisfaction
Excessive sedation
•Prolonged mechanical
ventilation, ICU LOS
– Tracheostomy
– DVT, VAP
•Additional testing
•Added cost
•Inability to communicate
•Cannot evaluate for
delirium
C
Choice of
Analgesics and Sedatives
The Ideal ICU Sedative
•Rapid onset of action and rapidly cleared.
•Predictable dose response
•Easy to administer
•Minimal drug accumulation
•Few adverse effects
•Minimal drug interaction
•Cheap

Pulls or removes tube(s) or catheters; aggressive
+2
Frequent non-purposeful movement, fights ventilator
+1
Anxious, apprehensive, but not aggressive
0
Alert and calm
-1
Awakens to voice (eye opening/contact) >10 sec
-2
Light sedation, briefly awakens to voice (eye opening/contact) <10 sec
-3
Moderate sedation, movement or eye opening. No eye contact
-4
Deep sedation, no response to voice, but movement or eye opening to physical stimulation

Diagnosis is Key !!
Confusion Assessment Method for the ICU (CAM-ICU)
Feature 1: Acute change or
fluctuating course of mental status
And
Feature 2: Inattention
And
Feature 3: Altered level of
consciousness

Diagnosing Delirium in Patient on
Mechanical Ventilation
Letter A test
• “SAVEAHAART”
•Say above 10 Letters
& instruct patient to
squeeze hand every
time you say letter
“A”
•Inattention PRESENT if
> 2 errors

Exercise and Mobility
E
Early Progressive
Exercise and Mobility
Early progressive mobility programs
result in:
 Better patient outcomes
 Shorter hospital stays
 Decreased development of
hospital acquired complications
The level of exercise and mobility is
individualized and incrementally
progressed
E
Immobility not beneficial
and associated with harm
– Myopathy/neuropathy
– Delayed weaning from
ventilator
– Delirium
– Infections
– Pressure ulcers
Early Exercise in the ICU
•Early exercise = progressive mobility
•Study design: paired SAT/SBT protocol with PT/OT from earliest
days of mechanical ventilation
Wake Up, Breathe, and Move

Early Progressive Exercise and Mobility
•All patients are candidates for mobilization if:
– No clinical contraindications to physical activity
– Pass a safety screen for participation
• Patients initially not eligible mobilization or who
have had interruptions in exercise will continually
reassessed for participation
• The level of exercise and mobility is individualized
and incrementally progressed
ICU Data Collection
Just Count Something
“No matter what you ultimately do in
medicine a doctor should be a scientist in his
or her world.
In the simplest terms, this means that we
should count something…It doesn’t really
matter what you count.
You don’t need a research grant. The only
requirement is that what you count should be
interesting to you.”
Atul Gawande
ICU Database
• Let’s us look above the daily grind.
• Illuminates random experiences.
• Concrete uses:
• Measuring utilization
• Measuring performance
• Platform for clinical research
MICU Database
MICU Database
•95% of data entered by nursing/clerical staff
•Fellows responsible for:
– Primary MICU diagnosis
– Select comorbidities (yes or no)
– APACHE scores
•Coming to Methodist
•Regular feedback of data
Infection Control
ICU Infection Control
•Key Performance Measure for ICU
•Hospital Compensation from Payors at Risk
•Intensivist’s Bonuses at Risk!!!
Infections with Surveillance Programs
1. Central Line Associated Bloodstream Infections (CLASBI)
2. Ventilator-Associated Pneumonia (VAP)
3. Catheter-Associated Urinary Tract Infection (CAUTI)
4. Clostridium Difficile Colitis
Reducing ICU-Acquired Infections
•CLASBI
– Insertion bundle
– Avoid femoral site
– No blood draws through catheter
– Good catheter maintenance
– Remove when not needed
•VAP
– Shorten duration of mechanical ventilation: Daily SAT/SBT
– VAP Bundle
•CAUTI:
– Don’t place foley if not necessary
– Get Foley’s out when not needed
•Clostridium Difficile: Limit unnecessary antibiotics
Be Careful Out There
